Description

  The present invention relates to a building having a space between indoors.

When an air conditioner as an air conditioner is provided in a building such as a house, the temperature and humidity of the indoor space are adjusted by operating the air conditioner. However, it is thought that the energy saving effect is low in the air conditioning by the air conditioner. Therefore, for example, in Patent Document 1, a garden capable of storing water is provided adjacent to a building, and the garden space and the indoor space are communicated with each other by an opening such as a window formed on the outer wall. Is disclosed. In this configuration, the temperature of the garden air decreases due to the heat of vaporization of water, and when the air flows as cool air from the opening to the indoor space, the temperature of the indoor space decreases. In this case, since the so-called hammering effect can be obtained, energy saving can be achieved.
JP 2007-162388 A

  However, in the configuration disclosed in Patent Document 1, if the opening of a window or the like is closed by a sash door or the like, the garden air does not flow into the indoor space, and thus the temperature of the indoor space cannot be adjusted. . Furthermore, since the temperature of the garden air is highly dependent on the outdoor environment such as the outside air temperature and the strength of the wind, it is considered difficult to adjust the indoor temperature appropriately. Therefore, there is room for improvement with respect to a configuration in which the indoor space is air-conditioned by vaporization of water.

  The main object of the present invention is to suitably air-condition indoor spaces by vaporizing water in buildings with dirt.

  In order to solve the above-mentioned problem, a first invention is a building having a soil space indoors, is provided below the soil floor surface and is opened upward from the soil floor surface, and further has water. A water retention unit that accumulates or flows and a water supply device that supplies water to the water retention unit are provided.

  According to the first invention, when water is present in the water retaining portion, the temperature and humidity of the air near the soil floor changes as the water vaporizes, and the air spreads in the indoor space. As a result, the temperature and humidity of the indoor space change. In other words, the indoor space is air-conditioned by the water in the water retention unit. In this case, for example, the energy saving effect can be enhanced as compared with the case where air conditioning of an indoor space is performed by an air conditioner. Moreover, unlike the case where cool air is taken into the indoor space by, for example, watering the outdoor ground, it is not necessary to open the opening that leads to the outdoor space, and it depends on the temperature and humidity of the outside air when air conditioning the indoor space. There is no end to it. As a result, the indoor space can be suitably air-conditioned by vaporizing water.

  It is preferable that the soil is provided adjacent to a living room space such as a living room, and an entrance such as a sweep window is provided on the outer wall that partitions the soil and the outside. In this case, since the resident can use the soil between the living room space and the outside, articles can be easily put in and out of the living room space from the outside. Moreover, since the air in the vicinity of the soil is more likely to reach the living room space compared to the configuration in which the water retaining portion is formed between the soils such as the entrance, the air conditioning of the living room space can be performed efficiently. As a result, the air conditioning efficiency of the indoor space can be improved while improving the usability of the soil.

  In 2nd invention, the said water retention part is a groove part formed in the said soil floor surface.

  According to the second aspect of the invention, since the water retaining part is formed by the groove part, substantially the entire water retaining part is opened upward. In this case, even if foreign matter such as stones or dust enters the groove portion, it is easy to remove the foreign matter from the open side of the groove portion, so that the maintenance work for the water retention portion is facilitated. On the other hand, for example, in a configuration in which the water retention part is partially opened upward like a water pipe having a plurality of holes on the peripheral surface, foreign substances clogged in the water retention part may be found or removed. It becomes difficult. Therefore, it is suitable for the air-conditioning system which air-conditions with the water of a water retention part to form a water retention part in a groove part.

  Moreover, it is preferable to provide the control means which controls the said air blower according to the environment of indoor space. In this case, the air blower can be operated when an air flow is required in the indoor space, and the operation of the air blower can be stopped when the air flow is not necessary. For example, the blower is operated when there is no person between the soils, and the blower is not operated when there is a person between the soils. Thereby, it can avoid giving a resident discomfort with a wind, air-conditioning the indoor space as a whole and efficiently.

  According to a seventh aspect of the present invention, the air passage includes a ventilation path that communicates a space near the dirt floor in the indoor space and an outdoor space, and an opening and closing device that opens and closes the ventilation path.

  According to the seventh aspect of the present invention, when the air passage is open and the outside air flows into the indoor space through the air passage, the air whose temperature and humidity are changed by the water in the water retaining portion in the vicinity of the soil floor surface is converted into the indoor space. It is possible to spread over a wide area. In other words, the indoor space can be air-conditioned as a whole and efficiently by the water in the water retention unit. In addition, in this case, the energy saving effect can be enhanced as compared with the configuration in which the air is forcibly sent by a blower or the like.

  In addition, as the ventilation path that communicates the dirt space near the dirt floor between the soil and the outdoor space, a vent formed in the outer wall that partitions the dirt and the outdoors, a ventilation duct that communicates from the vicinity of the dirt floor to the outdoors, etc. Is mentioned.

  Moreover, it is preferable to provide a control means for controlling the switchgear according to the environment of the indoor space. In this case, the air passage can be opened when the air flow is required in the indoor space, and the air passage can be closed when the air flow is not required. For example, the air passage is opened when there is no person between the soil, and the air passage is closed when there is a person between the soil. Thereby, it is possible to avoid discomforting the resident due to the outside air while air-conditioning the indoor space as a whole and efficiently.

  Furthermore, an outside air temperature detecting means for detecting the temperature of the outside air and an outside air humidity detecting means for detecting the humidity of the outside air are provided, and the control means opens and closes the open / close based on the detection results of the outside air temperature detecting means and the outside air humidity detecting means. It is preferable to control the apparatus. In this case, when the outside air has a temperature or humidity that is not suitable for air conditioning the indoor space, the outside air does not flow into the indoor space by closing the air passage. For example, when the difference between the target temperature of the indoor space and the temperature of the outside air is larger than a predetermined value, the ventilation path is closed. In this case, since the temperature of the indoor space can be adjusted without depending on the temperature of the outside air, the efficiency of temperature adjustment can be increased.

The earth 12 is disposed between the living room 11 and the outer wall 14 and is adjacent to the garden 15 with the outer wall 14 in between. In addition, the living room 11 is separated from other indoor spaces such as a corridor by an inner wall 17.

  In the living room 11, a floor joist 21 disposed on a floor beam or the like is provided, and a floor base material 22 is provided on the floor joist 21. The floor joists 21 are long materials arranged so as to extend in the horizontal direction, and a plurality of the floor joists 21 are arranged side by side at a predetermined interval. The floor base material 22 is a floor panel material formed of, for example, plywood or particle board, and is disposed so as to extend in the horizontal direction. A floor finishing material 23 such as flooring is provided on the floor base material 22 so as to overlap, and a living floor 25 is formed by the upper surface of the floor finishing material 23.

  The interstices 12 are formed in a substantially rectangular shape in plan view by the concrete layer 27 and are arranged so as to extend along the living room 11. The upper surface of the concrete layer 27 is exposed, and the soil floor surface 28 is formed by the upper surface. The level of the dirt floor 28 is equal to the ground level GL of the ground outdoors, and is about 30 cm lower than the floor level FL of the living floor 25 in the living room 11, for example.

  A stepped portion 31 is formed at the boundary between the living room 11 and the soil 12, and the height of the stepped portion 31 corresponds to a level difference between the ground level GL and the floor level FL. The step portion 31 is provided with a kick plate 32 so as to stand up from the dirt floor surface 28, and the kick plate 32 connects the dirt floor surface 28 and the living floor surface 25. This prevents articles such as shoes from entering the floor of the living room 11.

  An entrance / exit 34 such as a sweep window is formed in a portion of the outer wall 14 between the soil 12 and the garden 15. The entrance / exit 34 is disposed on the opposite side of the living room 11 with the dirt 12 interposed therebetween, and the entrance / exit 34 is provided with a pair of sliding sash doors 35. The sash door 35 slides to open and close the entrance 34 and has a sash frame 36 and a glass plate 37 fitted in the sash frame 36.

The purification device 44 has a water supply section such as a pump and a switching section such as a valve for switching the water supply destination to the circulation pipe 46 or the drain pipe 47, and the discharge groove is driven by driving the water supply section and the switching section. The water from 43 is sent to the water supply device 42 as purified water, or flows into the drain pipe 47 as drainage. In addition, when the water from the discharge groove 43 flows as drainage into the drainpipe 47, the drainage may be configured to flow through the drainpipe 47 without passing through the purification device 44.

  In addition to the circulation pipe 46, a water pipe 48 is connected to the water supply device 42. The water supply device 42 has a water supply unit such as a pump, an adjustment unit such as a valve that adjusts the amount of water supplied from the water supply unit, and a switching unit such as a valve that switches the water supply source to the circulation pipe 46 or the water pipe 48. The tap water or purified water is supplied to the water supply groove 41 by driving the water supply unit, the adjustment unit, and the switching unit. That is, tap water or purified water is supplied to the groove 39. When purified water is supplied to the groove 39, the drainage in the soil 12 is reused, and water saving is realized.

  The water supply device 42 has a heater portion 49 as a heating device. The heater unit 49 includes an electric heater or the like, and can heat tap water or purified water. That is, it is possible to supply not only water but also hot water to the water supply groove 41.

  The water supply groove 41 and the discharge groove 43 are respectively arranged so as to extend orthogonally to the groove portion 39, and are opened upward and curved in an arcuate shape downward from the soil floor 28 in the cross section, like the groove portion 39. Recessed to do. Further, the water supply groove 41 and the discharge groove 43 have a width of about 5 mm, for example, and a depth of about 10 mm. The water supply groove 41 is gently inclined so that the bottom surface of the end portion on the opposite side is deeper than the bottom surface of the end portion on the water supply device 42 side. Further, the water supply groove 41 is connected to the end portion of each groove portion 39 having a shallow bottom surface, and the bottom surface of the water supply groove 41 is shallower than the bottom surface of the groove portion 39 at the connection portion. Therefore, water can easily flow from the water supply device 42 to the groove 39.

  The discharge groove 43 is gently inclined so that the bottom surface of the end portion on the purification device 44 side is deeper than the bottom surface of the opposite end portion. Further, the discharge groove 43 is connected to the deeper end portion of each groove portion 39, and the bottom surface of the discharge groove 43 is deeper than the bottom surface of the groove portion 39 at the connection portion. Therefore, water can easily flow from the groove 39 to the purification device 44.

  In addition, the groove part 39, the water supply groove | channel 41, and the discharge groove | channel 43 are formed by cutting only the surface vicinity of the concrete layer 27 with the cutter apparatus which can cut | disconnect the concrete layer 27. FIG. That is, the cut is made in the concrete layer 27 by the cutter device.

  Returning to the description of FIG. 1, an air passage capable of taking outside air into the indoor space is formed in the soil 12. A sash door vent 61 and an outer wall vent 62 are provided as vent paths, and the vents 61 and 62 communicate the indoor space and the outdoor space, respectively. The sash door vent 61 is disposed at the lower part of the sash door 35 and is formed in a horizontally long, substantially rectangular shape so as to extend along the dirt floor 28. Note that the sash door vent 61 is disposed below the sash door 35 by being disposed below the glass plate 37 inside the sash frame 36. The outer wall vent 62 is disposed in a portion of the outer wall 14 that is orthogonal to the portion where the doorway 34 is disposed, and is formed in a horizontally long, substantially rectangular shape so as to extend along the dirt floor 28.

  The sash door vent 61 is fitted in the sash door vent 61. The sash door vent louver 65 is formed in substantially the same size and shape as the sash door vent 61. Similarly, the outer wall vent 62 is fitted with an outer wall vent 66. The outer wall vent louver 66 is formed in substantially the same size and shape as the outer wall vent 62. Each vent louver 65, 66 is configured to be able to close each vent 61, 62 as an opening / closing device.

  Each vent louver 65, 66 will be described. Since each vent gallery 65, 66 has the same configuration, the sash door vent 65 will be described here with reference to FIGS. FIG. 3 is a front view showing the configuration of the sash door 35, and FIG. 4 is a schematic longitudinal sectional view of the sash door 35. 4A is a diagram when the slat 72 is in the closed state, and FIG. 4B is a diagram when the slat 72 is in the open state.

  As shown in FIG. 3, the sash door vent louver 65 has a louver frame 71 formed in a substantially rectangular shape, and a plurality of slats 72 are provided inside the louver frame 71. Each slat 72 is formed in the shape of a horizontally long plate, and these slats 72 are arranged vertically. Each slat 72 is rotatably supported by a support portion 73, and shifts to an open state or a closed state by rotating. The rotation shaft of each slat 72 extends in the horizontal direction. The sash door vent gallery 65 is provided with a sash drive unit 75 constituted by a motor or the like. When the sash drive unit 75 is driven, the support unit 73 operates to rotate each slat 72. Let

  As shown in FIG. 4A, the slats 72 stand up in the vertical direction when in the closed state, and there is no gap between the slats 72 adjacent in the vertical direction. Even if there is a gap, the gap is extremely small. In this case, the sash door vent 61 is closed when the sash door vent louver 65 is closed, and the flow of outside air to the dirt 12 is restricted. Moreover, the slat 72 shifts to an open state by rotating. As shown in FIG. 4B, when the slat 72 is in an open state, the slat 72 is inclined downward toward the soil 12 side, and a gap is formed between the slats 72 adjacent in the vertical direction. In this case, the sash door vent 61 is opened when the sash door vent louver 65 is in an open state, and the outside air can flow into the dirt 12 side.

  The outer wall vent louver 66 has the same configuration as the sash door vent louver 65, but has an outer wall drive unit 79 (see FIG. 5) instead of the sash drive unit 75, and the outer wall drive When the part 79 is driven, the state is switched between the open state and the closed state. When the outer wall vent 66 is in the open state, the outside air can flow into the soil 12 side from the outer wall vent 62, and when it is in the closed state, the flow of outside air from the outer wall vent 62 is restricted.

  Returning to the description of FIG. 1, a blower 53 that sends out air toward the dirt floor 28 is provided below the floor of the living room 11. The blower 53 includes a fan, and sends out air by the rotation of the fan accompanying the drive of the drive unit. The blower 53 is disposed close to the kick plate 32, and a blower port 54 for sending air to the soil 12 is formed in a portion of the kick plate 32 facing the blower 53. A blower louver 55 is fitted in the blower opening 54. The blowing gallery 55 has a plurality of fins, and each fin is inclined downward toward the dirt floor 28. In this case, the blown louver 55 directs the direction of the wind sent out from the blower 53 toward the dirt floor 28 and restricts articles and the like from entering the floor of the living room 11 through the blower port 54.

  On the inner wall 17 that partitions the living room 11 from other building spaces such as a corridor, an indoor side air vent 82 that connects the living room 11 and the other building space is formed. The indoor side air vent 82 is formed in a horizontally long and substantially rectangular shape, and is disposed on the upper portion of the inner wall 17 so as to extend along the ceiling of the living room 11. An opening / closing body 83 that opens and closes the indoor side air vent 82 is pivotally supported on the inner wall 17 so as to be rotatable. In the present embodiment, the opening / closing body 83 is held in an open state, and ventilation through the indoor side air vent 82 is always performed.

  In the soil 12 of the present embodiment, an air conditioning system is constructed that air-conditions the soil 12 and the living room 11 by flowing water through the groove 39. Here, an electrical configuration related to the air conditioning system will be described with reference to FIG.

  As shown in FIG. 5, the air conditioning system includes a home server 85 as control means. The home server 85 includes a microcomputer including a CPU, various memories, and the like, and includes an operation unit 86 and a storage unit 87 operated by a person. The operation unit 86 includes an input unit such as operation buttons and a display unit such as a display. A person operates the input unit while viewing the screen displayed on the display unit, thereby setting the target temperature and target humidity of the living room 11. It can be set appropriately. The target temperature and target humidity are stored in the storage unit 87 as information related to the air conditioning of the living room 11.

  The home server 85 detects an indoor temperature sensor 91 that detects the temperature of the living room 11, an indoor humidity sensor 92 that detects the humidity of the living room 11, an outdoor air temperature sensor 93 that detects the outdoor temperature, and an outdoor humidity. An outside air humidity sensor 94 and an anemometer 95 that detects an outdoor wind speed are connected, and these sensors 91 to 95 output detection signals to the home server 85. The indoor temperature sensor 91 and the indoor humidity sensor 92 are installed, for example, on the wall surface of the living room 11, and the outside air temperature sensor 93, the outside air humidity sensor 94, and the anemometer 95 are respectively installed on the outdoor side surface of the outer wall 14, for example.

  The home server 85 is connected to a water supply device 42, a purification device 44, a blower device 53, a sash drive unit 75 for the sash door vent gallery 65, and an outer wall drive unit 79 for the outer wall vent gallery 66. The home server 85 controls the operation of the devices 42, 44, 53 and the drive units 75, 79 by outputting a command signal. In particular, for the water supply device 42, information about the amount of water supplied to the groove 39 is stored in the storage unit 87, and the home server 85 adjusts the amount of water supplied from the water supply device 42 based on the water amount information.

  Next, control processing of the air conditioning system executed by the home server 85 will be described with reference to the flowchart of FIG. The home server 85 repeats this control process at a predetermined time period.

  In FIG. 6, in step S101, detection signals from the indoor temperature sensor 91, the indoor humidity sensor 92, the outside air temperature sensor 93, the outside air humidity sensor 94, and the anemometer 95 are acquired. In step S102, it is determined whether or not the living room 11 is to be air-conditioned. In this case, the target temperature and the target humidity are acquired from the storage unit 87, and the actual temperature and the actual humidity of the living room 11 are acquired based on the detection signals of the indoor temperature sensor 91 and the indoor humidity sensor 92. It is determined whether or not there is a difference between the actual temperature and the actual humidity. If either one is different, the living room 11 is air-conditioned and the process proceeds to step S103. Moreover, when all are the same, this control process is complete | finished as it is not performing air conditioning of the living room 11.

  In step S103, operation control of the water supply apparatus 42 is performed. Here, when the actual temperature is higher than the target temperature, water is supplied from the water supply device 42 to the water supply groove 41, and water is allowed to flow through the groove portion 39. In this case, the air near the soil floor 28 is cooled by the heat of vaporization of the water flowing through the groove 39. Further, when the actual temperature is lower than the target temperature, the heater unit 49 is driven to heat the water, hot water is supplied from the water supply device 42 to the water supply groove 41, and the hot water is caused to flow into the groove 39. In this case, the air in the vicinity of the dirt floor 28 is warmed by the hot air flowing through the groove 39. Further, when the actual humidity is lower than the target humidity, water or hot water is poured into the groove 39 according to the actual temperature at that time. In this case, moisture is added to the air in the vicinity of the dirt floor 28 by water or water flowing through the groove 39 being vaporized. In short, the temperature of the air near the dirt floor 28 is adjusted and the humidity is adjusted. In addition, when hot water is poured into the groove part 39, the vaporization of hot water is promoted and humidification is performed more efficiently than when water is passed through the groove part 39.

  In addition, when performing operation control of the water supply apparatus 42, water amount information is acquired from the memory | storage part 87, and the water supply amount from the water supply apparatus 42 is adjusted so that water and hot water may not overflow from the groove part 39. FIG. For example, as shown in FIG. 1, the amount of water supply is adjusted so that an amount of water smaller than half of the volume of the groove 39 flows in the groove 39. That is, the water supply amount is adjusted so that the water surface is lower than the dirt floor 28 by a predetermined height. Moreover, since the surface of the flowing water is likely to bend along the curved bottom surface due to the surface tension, the surface area of the water is increased compared to the case where the surface is not bent, and the vaporization of water and hot water is promoted.

  In step S104, it is determined whether or not outside air is taken into the soil 12 or the living room 11. For example, the actual temperature of the outside air is acquired based on the detection signal of the outside air temperature sensor 93, and it is determined that the outside air is taken in when the difference between the actual temperature and the target temperature is smaller than the difference between the actual temperature and the target temperature of the living room 11. . This is because the temperature of the living room 11 can be adjusted efficiently when outside air is taken in, and the living room 11 and the soil 12 can be ventilated. Further, the actual humidity of the outside air is acquired based on the detection signal of the outside air humidity sensor 94, and it is determined that the outside air is taken in when the actual humidity is lower than both the target humidity and the actual humidity of the living room 11. This is because it is difficult to reduce the humidity of the living room 11 by flowing water or hot water through the groove 39. Furthermore, even if it is determined that the outside air is taken in by the above determination, the actual outdoor wind speed is acquired based on the detection signal of the anemometer 95, and the outside air taking-in determination is permitted when the actual wind speed is equal to or lower than the predetermined wind speed. Thereby, it can avoid that a strong wind blows into the dirt 12 or the living room 11.

  In step S105, operation control of the sash drive unit 75 of the sash door vent gallery 65 and the outer wall drive unit 79 of the outer wall vent gallery 66 is performed. Specifically, the outside air is taken into the soil 12 from the sash door vent 61 and the outer wall vent 62 by shifting the slats 72 of the sash door vent louver 65 and the outer wall vent louver 66 to the open state. In this case, outside air flows into the vicinity of the soil floor 28, and the air in the living room 11 and the soil 12 flows out of the indoor vent 82 into another building space, so that the temperature existing in the vicinity of the soil floor 28 is adjusted. The air whose humidity has been adjusted can easily reach the entire space of the soil 12 and the living room 11. As a result, a cooling effect, a heating effect, and a humidifying effect are imparted to the earth 12 and the living room 11 as a whole.

  In step S106, it is determined whether or not the wind is forcibly sent to the dirt floor 28. For example, the case where the actual temperature and humidity of the living room 11 do not change even though the slats 72 of the sash door vent 65 and the outer wall vent 66 are moved to the open state, or because the outdoor is a strong wind. When each slat 72 cannot be shifted to the open state, it is determined that air is blown. When it determines with performing ventilation, it progresses to step S107 and operation control of the air blower 53 is performed. In this case, air is blown out from the blower 53 toward the dirt floor 28, so that the temperature-adjusted or humidity-adjusted air existing in the vicinity of the dirt floor 28 is forcibly applied to the space in the dirt 12 or the living room 11. Can be spread throughout.

  In addition, as long as the sash door vent 65 and the outer wall vent 66 can adjust the opening of the slat 72, the opening of the slat 72 may be adjusted in accordance with the actual outdoor wind speed. In this case, by reducing the opening of the slat 72 even if the actual outdoor wind speed is higher than the predetermined wind speed, the outside air is passed through the soil 12 and the living room 11 so that strong wind is not blown into the sash door vent 61 and the outer wall vent 62. Can be captured. Further, if the anemometer 95 detects the wind direction, outside air may be taken from one of the sash door vent 61 and the outer wall vent 62 in accordance with the detected wind direction.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In this air conditioning system, the temperature and humidity of the living room 11 and the soil 12 can be adjusted by flowing water into the groove 39 of the soil 12. In this case, an energy saving effect can be obtained as compared with the configuration in which the living room 11 and the soil 12 are air-conditioned by the air conditioner. Further, in this case, since it is possible to obtain the effect of hammering water in the earth 12, it is not always necessary to take in the outside air when the hammering effect is obtained, unlike the case where the hammering is performed outdoors. Therefore, the convenience of this air conditioning system can be improved.

  By blowing air from the blower 53 and taking in outside air from the sash door vent 61 and the outer wall vent 62, the air in the vicinity of the dirt floor 28 is easily distributed to the living room 11 and the earth floor 12, and the living room 11 and the earth 12 The entire space can be suitably air-conditioned. In this case, since the wind hits the water and hot water flowing through the groove 39, the amount of water and hot water vaporized increases, and the temperature and humidity of the air can be adjusted efficiently near the dirt floor 28. it can. As a result, the living room 11 and the soil 12 can be efficiently air-conditioned.

  By shifting the sash door vent louver 65 and the outer wall vent louver 66 to the open state, not only temperature adjustment and humidity adjustment but also ventilation are performed for the living room 11 and the soil gap 12. In this case, air conditioning and ventilation in the building space can be performed together.

  Since the groove 39 is sufficiently thinner than the size of a person's foot, it is possible to avoid the foot of a person walking on the dirt floor 28 from entering the groove 39. In addition, since the water surface in the groove 39 is lower than the interstitial floor surface 28 by a predetermined height, the interstitial floor surface 28 can be held in a dry state. Therefore, it is possible to avoid that a person's feet riding on the dirt floor surface 28 get wet or an article placed on the dirt floor surface 28 gets wet. As a result, even if water flows in the groove 39, it is not necessary for a person to walk across the groove 39 or place an article on the floor 28 so as not to be placed on the groove 39. You can avoid getting worse.

  Since the groove part 39 is provided in the soil 12 adjacent to the living room 11 as a living room space, the living room 11 having a long residence time can be suitably air-conditioned. In addition, since the frequency used when people enter and leave the building 10 is lower than that of the entrance and the doorway, dirt, dirt, etc. in the groove portion 39 compared to the structure in which the groove portion 39 is provided between the soil such as the entrance and the doorway. Is less likely to get foreign material. Therefore, the maintenance work can be facilitated. In addition, since footwear such as shoes is rarely placed on the dirt floor 28, the water in the groove 39 is more easily vaporized than the entrance where many footwear is supposed to be placed, and air conditioning can be performed efficiently.

  Since the water easily flows through the groove portion 39 by inclining the bottom surfaces of the groove portion 39, the water supply groove 41, and the discharge groove 43, the soil 12 is kept hygienic as compared with the configuration in which water is stored in the groove portion 39. Can do. This is because in the groove portion 39, it is more likely that the propagation of bacteria and the like is promoted when water is accumulated than when water is flowing.

  As a result of the above, the air-conditioning of the indoor space such as the living room 11 and the soil space 12 can be suitably performed by vaporization of the water flowing in the groove 39.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) In the dirt 12, a temporary floor may be provided above the dirt floor 28. For example, as shown in FIG. 7, the temporary floor portion 101 is configured to be detachably installed in the earth 12. The temporary floor portion 101 includes a floor plate 102 that extends in the horizontal direction and a leg portion 103 that supports the floor plate 102. The floor plate 102 is formed in a substantially rectangular shape in plan view, and a temporary floor surface 105 is formed by the upper surface thereof. The floor plate 102 is formed with a plurality of slits 107 penetrating the floor plate 102 in the vertical direction. Each slit 107 extends in the longitudinal direction of the floor plate 102 and is arranged in the short direction of the floor plate 102. In addition, the floor board 102 may be formed of “sunoko”.

  The length of the floor plate 102 in the short direction is substantially the same as the length in the short direction of the earth 12, and the longitudinal direction thereof is shorter than the length of the earth 12. That is, the floor board 102 partially covers the dirt floor 28. In the temporary floor portion 101, the floor plate 102 may be formed in the same shape and size as the dirt floor 28. That is, the floor board 102 may cover the entire dirt floor 28.

  The leg portions 103 support the floor plate 102 so that the temporary floor surface 105 has the same height as the living floor surface 25, and are disposed at both ends of the floor plate 102 in the short direction, along the longitudinal direction of the floor plate 102. It extends.

  When the temporary floor 101 is installed in the soil 12, a person can use the installation part of the temporary floor 101 in the soil 12 as if it is a part of the living room 11. That is, the earth 12 can be used as if the living room 11 is wide. Further, in this case, the air in the vicinity of the dirt floor 28 flows out above the temporary floor 105 through the slit 107, so that the temperature and humidity of the living room 11 and the dirt 12 are adjusted by the water in the groove 39. The living room 11 and the earth 12 can be air-conditioned by the water in the groove 39 while improving the convenience of the earth 12.

  Further, as a configuration in which the temporary floor surface 105 is provided above the dirt floor surface 28, as shown in FIG. 8A, the floor plate 102 is pivotally supported with respect to the indoor side surface of the outer wall 14. Is mentioned. In this configuration, the rotation axis of the floor board 102 extends in the horizontal direction along the longitudinal direction of the earth 12 and a stopper for holding the floor board 102 in a horizontal state and a vertical state is provided. When the floor board 102 is held in a horizontal state, the temporary floor surface 105 of the floor board 102 is on the same plane as the living floor 25. On the other hand, when the floor board 102 is held in a vertical state, the floor board 102 is stored in a state of standing along the indoor side surface of the outer wall 14. Therefore, a person can install and remove the temporary floor 105 by a simple operation of simply rotating the floor board 102. In addition, when the temporary floor 105 is removed, the floor board 102 can be stored in the earth 12, so that it is not necessary to carry the floor board 102 from the earth 12 to another place. That is, the usability of the floor 101 can be improved.

  Furthermore, as a configuration in which the temporary floor surface 105 is provided above the dirt floor 28, the floor plate 102 is installed so as to slide in the horizontal direction as shown in FIG. A configuration that appears above and below the surface 28 is exemplified. In this configuration, the floor board 102 is stored under the floor of the living room 11, and the floor board 102 appears above the inter-soil floor 28 by sliding to the inter-soil 12 side. In this case, since it is not necessary to secure a storage space for the floor board 102 in the soil 12, the entire soil 12 can be used effectively when the temporary floor surface 105 is removed. Incidentally, in this case, the level of the temporary floor surface 105 is lower than that of the living floor surface 25 by the joists 21, the floor base material 22, and the floor finishing material 23 (all not shown).

  As shown in FIG. 7, the outer wall vent 62 may not be provided in the outer wall 14, and the air outlet 54 may not be provided in the step portion 31. Further, as shown in FIG. 8, the entrance / exit 34 may not be provided in the outer wall 14.

  (2) The groove 39 may be provided outdoors. For example, as shown in FIG. 9, the concrete layer 27 is formed in the garden 15 in addition to the soil 12, and the groove 39 is provided in the concrete layer 27 in both the soil 12 and the garden 15. In this configuration, the water supply groove 41 and the discharge groove 43 (not shown) are formed so as to extend from the soil space 12 to the garden 15, and water is supplied from the water supply device 42 (not shown), so that the groove portion 39 of the soil space 12. Not only does the water flow into the groove 39 of the garden 15. In this case, since the water spray effect can be obtained in the garden 15, the doorway 34 is opened or the sash door vent louver 65 of the sash door 35 is moved to the open state, thereby flowing through the groove 39 of the garden 15. Outside air whose temperature and humidity have been adjusted with water is taken into the soil 12. Thereby, compared with the structure by which the groove part 39 is provided only in the soil 12 adjacent to the living room 11, the air conditioning by the water of the groove part 39 can be performed efficiently.

  In addition, the groove part 39 may be formed in the soil which is not adjacent to the living room 11 or the garden 15, such as an entrance and a doorway.

  (3) The groove 39 may not be formed linearly. For example, as shown to Fig.10 (a), it is set as the structure which made the groove part 39 meander so that it might extend in the longitudinal direction of the dirt 12. In this case, since it becomes possible to lengthen the groove part 39 compared with the structure by which the groove part 39 is formed in linear form, the surface area of water is enlarged in one groove part 39, and vaporization of water is further promoted. be able to. That is, the air conditioning of the building space can be performed efficiently. Further, the groove portion 39 may not have a uniform width.

  (4) In the dirt 12, the dirt floor 28 may be formed of a dirt floor finish. For example, as shown in FIG. 10 (b), a plurality of tiles 111 are provided on the concrete layer 27 as the floor finishing material. In this configuration, a gap (joint) is formed between adjacent tiles 111, and a groove 39 is formed by the gap. The gaps between the tiles 111 are uniform, and the groove 39 extends over the entire dirt floor 28 so as to extend in the vertical and horizontal directions. That is, the groove 39 is formed in a lattice shape. In this case, since the groove portion 39 extends so as to intersect in two directions, the groove portion 39 can be made longer than the configuration in which the groove portion 39 is formed to extend in one direction. Therefore, the surface area of the water flowing through the groove 39 on the dirt floor 28 can be increased, and the vaporization of the water can be further promoted. That is, the air conditioning of the building space can be performed more efficiently.

  Moreover, as shown in FIG.10 (c), the water absorbing materials 112, such as sponge with high water absorption, may be provided in the groove part 39 formed between the tiles 111. FIG. In this case, even when water is not supplied from the water supply device 42 to the groove 39, it is possible to retain water in the groove 39 by the water absorbing material 112. It can be performed.

  Furthermore, as shown in FIG. 10D, the tile 111 may be provided on a water retention layer 115 as a water retention portion having high water retention. In this case, similarly to the configuration in which the water absorbing material 112 is provided in the groove portion 39, even when water is not supplied from the water supply device 42 to the groove portion 39, the water inside the building is retained by the water retaining layer 115. Air conditioning can be performed. Examples of the water retention layer 115 include concrete layers and clay layers with high water retention.

  (5) It is good also as a structure by which water is stored by the groove part 39 as a water retention part. For example, when the water supply device 42 supplies water to the groove portion 39 and the purification device 44 does not discharge water to the circulation pipe 46 and the drain pipe 47, the water is stored in the groove portion 39 so as not to overflow. Water supply from the water supply device 42 is stopped. In this case, even if the water supply device 42 and the purification device 44 are not always driven, the air in the building space is air-conditioned by the water in the groove 39, so that further energy saving can be achieved.

  (6) The groove part 39 does not have to be recessed so as to be curved downwardly from the dirt floor 28 in the cross section. For example, as shown to Fig.11 (a), it is set as the structure where the groove part 39 is dented so that a groove width may become small continuously toward the downward direction from the dirt floor 28 in a cross section. That is, the groove 39 is recessed in a substantially V shape in the cross section. In this configuration, the size of the water surface changes depending on the amount of water flowing through the groove 39. Specifically, the size of the water surface when the water depth in the groove portion 39 is H1 is approximately half that of the water surface when the water depth is H2, which is approximately twice the water depth H1. . Here, when the amount of water flowing through the groove 39 increases, the amount of water vaporization increases. Therefore, by adjusting the amount of water supplied from the water supply device 42, the temperature and humidity of the space in the building can be finely adjusted.

  Moreover, as shown in FIG.11 (b), the groove part 39 is taken as the structure dented below in the substantially rectangular shape in the cross section. In this configuration, even if the water depth changes from H2 to H1, the size of the water surface does not change, so that the amount of water vaporization can be kept constant. Therefore, the shape of the groove 39 is preferably applied to a configuration in which air is stored in the groove 39 to store the water in the building. This is because even if the amount of water stored in the groove 39 decreases due to vaporization or the like, a certain air conditioning capability can be exhibited.

  (7) The water retaining part may have a configuration in which the area where water exists is not opened upward like the groove part 39 but the area where water exists is partially opened upward. For example, a pipe or a water tank as a water retaining part is buried in the soil 12 and the internal space of the buried pipe or the buried tank is opened upward (to the soil space side) through the opening. Even in this case, the water in the buried piping or the buried tank is vaporized, so that the air in the vicinity of the dirt floor 28 is temperature-adjusted and humidity-adjusted, so that the space in the building can be air-conditioned.

  (8) Domestic wastewater may be supplied to the groove 39. For example, a drain pipe of an air conditioner is connected to the purification device 44 and drainage water is supplied to the purification device 44. According to this configuration, drainage from the air conditioner is effectively used, and water saving can be realized. Similarly to the domestic wastewater, rainwater and domestic wastewater may be supplied to the groove 39.

  (9) The water supply device 42 may not be configured to heat water. For example, a solar water heater that can store water and that heats the stored water by sunlight is provided, and water heated by the solar water heater is supplied to the water supply device 42 as hot water. The configuration is as follows. In this configuration, a light receiving panel is installed on the roof of the building 10 in the solar water heater, and the heat receiving pipe with a high heat transfer property is built in the light receiving panel. In this case, the sunlight in the light receiving panel is heated to heat the water in the heat transfer pipe, so that hot water can be supplied to the groove 39 without driving the heater portion 49 of the water supply device 42. Yes. Therefore, the energy saving effect can be further enhanced when heating or humidifying the space in the building. Further, the hot water discharged from the kitchen or bath in the domestic wastewater may be supplied to the groove 39 after being purified by the purification device 44.

  In addition, a heater device that heats the water flowing through the groove 39 may be embedded in the soil 12. In this case, the indoor space can be efficiently heated and humidified by the hot water present in the groove 39.

  (10) The ventilation path capable of taking outside air into the living room 11 and the soil space 12 may be formed by a ventilation duct that connects the indoor space and the outdoor space. In this case, the position where the outside air flows can be adjusted by arbitrarily setting the position of the end of the ventilation duct in the indoor space. Thereby, it becomes easier to spread the air in the vicinity of the dirt floor 28 to the entire indoor space.

  (11) For example, an air conditioner may be provided as an air conditioner in the living room 11 or the earth 12. Even in this case, by supplying water to the groove 39 in addition to the operation of the air conditioner, energy saving can be achieved as compared with the case where the air conditioner is only air-conditioned.

  (12) The blower 53 may be installed so as to send out air toward the direction or place where air convection occurs in the living room 11 or the soil 12. Even in this case, the air in the vicinity of the soil floor 28 easily reaches the living room 11 and the soil space 12 due to air convection, so that the entire space of the living room 11 and the soil space 12 can be suitably air-conditioned. Further, when the vent louvers 65 and 66 are in an open state so that air convection is generated by the outside air flowing from the sash door vent louver 65 or the outer wall vent louver 66, the respective slats 72 are placed between the soil 12 It is good also as a structure which becomes the upward slope to the side. Furthermore, a discharge device for discharging the air in the vicinity of the dirt floor 28 to the outside or other building space may be provided.

  (13) A human sensor as a human detection means for detecting the presence of a person may be provided in the dirt 12 or the living room 11 as an indoor space. In this case, for example, the human sensor is electrically connected to the home server 85, and the home server 85 operates the blower 53 when no person is detected in the living room 11 or the earth 12, so that the living room 11 or the earth When a person is detected at 12, the operation of the blower 53 is stopped. According to this configuration, it is possible to avoid giving an unpleasant sensation to the occupant due to the wind while air-conditioning the indoor space as a whole.

  (14) In the air conditioning system, a floor surface temperature sensor for detecting the temperature of the dirt floor 28 may be provided. In this configuration, the floor surface temperature sensor is electrically connected to the home server 85, and the home server 85 performs control processing of the air conditioning system based on the detection result of the floor surface temperature sensor. In this case, since the operation control of the water supply device 42 and the like is broken in accordance with the temperature of the dirt floor 28, the accuracy can be improved during air conditioning of the space in the building.

  (15) The interstices 12 may be formed not by the concrete layer 27 but by stone or brick. Further, a fine aggregate such as gravel having a relatively large particle size may be formed of a “brush” -shaped fine bone layer in which a fine aggregate such as gravel is consolidated with a resin adhesive or the like. In the fine bone layer, water flows through the gaps between the fine aggregates below the dirt floor 28, and the gaps are opened upward, so that the fine bones can be formed even if the grooves 39 are not formed. By supplying water to the layers, the space in the building can be air-conditioned with the water.
