TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hot water injection type mist sauna device installed in, for example, a bathroom of a general household, and more particularly to a device capable of accurately controlling the temperature in a bathroom.
[0002]
[Prior art]
For example, a mist sensor device is installed in a unit bathroom in an apartment house or the like, and the bathroom is also used as a sauna room.
[0003]
Conventionally, in this type of mist sauna apparatus, for example, a spout hot water pipe connected to a hot water supply piping system of a bathroom is provided in an upper portion of an exterior body of a unit body, and hot water is heated from a hot water spout nozzle provided in the spout hot water pipe. While injecting the heat toward the exchanger, a fan unit is provided in the lower part of the outer body, and the fan unit draws air in the bathroom from the air inlet provided in the upper part of the outer body, and simultaneously blows air in the lower part of the outer body. There is one having a configuration in which heated air that has been heat-exchanged by a heat exchanger is blown out from an outlet.
[0004]
In addition, a remote controller installed on the wall surface of the bathroom near the air inlet inside the exterior body of the unit body or near the air intake outside the exterior body, or a remote controller installed on the wall surface of the bathroom has a temperature for measuring the temperature inside the bathroom. A thermistor as a detection device is installed, and by detecting the bath room temperature by the thermistor, the injection of the hot water from the hot water jet nozzle is controlled to control the temperature in the bathroom.
[0005]
[Problems to be solved by the invention]
However, in the mist sauna apparatus having the above-described conventional structure, when the fan unit is stopped or the injection of the hot water from the hot water jet nozzle is stopped, the hot air is generated by the fan unit or the hot water jet nozzle. The air suction function due to the negative pressure effect is also stopped, so that the air in the bathroom does not hit the thermistor during operation of the device, so that accurate temperature measurement by the thermistor cannot be performed, and the fluctuation of the bath room temperature during temperature control is large. Therefore, not only is the timing of restarting heating unknown, but also the work and wiring for the thermistor are troublesome.
[0006]
In addition, since the fan unit is incorporated in the exterior body, the entire apparatus becomes expensive and maintenance cannot be performed easily.
[0007]
Conventionally, at the same time that hot water is jetted from a hot water jet nozzle provided in a hot water pipe, air in the bathroom is taken in from a suction port provided at an upper portion of an exterior body by a negative pressure effect by the injection of the hot water, 2. Description of the Related Art There is known a hot-water injection type mist sauna device having a configuration in which heated air that has been heat-exchanged by injecting heated water is blown out from a blowout port provided in a lower portion of an exterior body.
[0008]
Such a hot water injection type mist sauna device does not require a fan unit to be incorporated in the exterior body, so that the cost and maintenance of the entire device can be reduced and the hot water injection nozzle is used for heating and suction. When the injection of hot water from the hot-water jet nozzle is temporarily stopped during temperature control during operation of the device, the suction function also stops, and However, there has been a problem that it is impossible to accurately measure the temperature of the air in the bathroom by the thermistor, and it is not possible to grasp the heating restart timing at the time of controlling the bathroom temperature.
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to provide a mist sauna apparatus which can accurately measure the temperature in a bathroom while the apparatus is operating, and can easily grasp the timing of restarting heating when controlling the temperature of the bathroom. is there.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a hot water jet nozzle provided in a hot water pipe connected to a hot water supply pipe system in a bathroom, and simultaneously jets hot water from the hot water jet nozzle. A temperature detecting device for detecting the temperature in the bathroom near the hot water jet nozzle is provided while the air in the bathroom is taken in from the air inlet and the heated air is discharged from the outlet by the negative pressure effect of Then, in a mist sauna device that controls the temperature in the bathroom by a temperature measurement value by the temperature detection device, the initial heating in which the bathroom is heated to a set temperature by injecting hot water from the hot water jet nozzle, The time from the constant temperature below the set temperature to the set temperature until the heating is resumed is stored, and when the temperature in the bath reaches the set temperature, the heating from the hot water jet nozzle is performed. After temporarily stopping the injection of hot water, is characterized in that performs control to repeat the ON · OFF of ejection of heating hot water from the hot water jet nozzle for each time heating to resume that the storage.
[0011]
Further, in the mist sauna device described above, at the time of initial heating in which the bathroom is heated to a set temperature by injecting hot water from the hot water jet nozzle, when the bathroom reaches the set temperature, The injection of the hot water from the hot water jet nozzle is stopped, and thereafter, the injection of the hot water from the hot water jet nozzle is repeated at regular intervals until the heating is resumed. The injection time is controlled so that the injection of the hot water from the hot water jet nozzle is stopped when the temperature in the bathroom reaches a set temperature.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the overall configuration of a bathroom in which a hot water injection type mist sauna device according to the present invention is installed. Is a unit body of the mist sauna device.
[0013]
As shown in FIGS. 2 and 3, the unit main body 1 is connected via an electromagnetic valve 3 to an exterior body 2 and a hot water supply pipe system for hot water H / W disposed at an upper portion inside the exterior body 2. And a plurality of hot-water jet nozzles 5 connected to the hot-water pipe 4.
[0014]
At the same time as the hot water H / W is injected from the hot water supply piping system from the hot water jet nozzles 5 during the operation of the apparatus, the exterior body is formed by the negative pressure effect of the injection of the hot water H / W. 2, air A in the bathroom is taken in from an air inlet 21 provided in an upper part of the outer body 2, and a heated air B heat-exchanged by hot water H / W is provided in a lower part of the exterior body 2. The air is blown out from the outlet 22 into the bathroom.
[0015]
In the figure, reference numeral 6 denotes a thermistor as a temperature detecting device installed at a position near the air inlet 21 in the exterior body 2 and at a position where the hot water H ・ W jetted from each of the hot water jet nozzles 5 does not directly hit. The thermistor 6 detects the temperature of the air A in the bathroom that is sucked in by the negative pressure effect of the injection of the hot water H · W injected from each of the hot water jet nozzles 5 during operation of the apparatus, as described later. The temperature in the bathroom is controlled by the measured temperature value.
[0016]
FIGS. 4 and 5 show an embodiment of a temperature control state in the mist sauna apparatus according to the present invention, in which the hot-water H.W injection from each hot-water jet nozzle 5 is stopped during the operation of the apparatus so that the bathroom is in the bathroom. When the heating is stopped, the inhalation of the air A in the bathroom stops, so that the thermistor 6 cannot detect the correct room temperature.
[0017]
On the other hand, as shown in FIG. 4, the temperature rise rate α (° C./min) immediately before the stop of the heating and the temperature decrease rate β (° C./min) at the time of the stop are almost inversely proportional. If the set temperature difference between the ON point of the operation switch and the OFF point when the heating operation is stopped is constant, the temperature rise rate α and the time T (minutes) until the restart of the heating are substantially proportional to each other as shown in FIG. Become.
[0018]
That is, when the temperature of the air A in the bathroom (outside air temperature) is high and the temperature rise rate α is high, heating is restarted after a while, and the temperature of the air A in the bathroom (outside air temperature) is low and the temperature rises. When the rate α is low, if the temperature is controlled so as to immediately restart the heating, the temperature can be set to almost the same ON point at any temperature of the air A (outside air temperature), and the ON point drops too much and the bath gets cold during bathing. It can also prevent things.
[0019]
Thereby, at the time of initial heating in which the hot water H · W is jetted from each hot water jet nozzle 5 to heat the bathroom to the set temperature, the heating from the constant temperature below the set temperature to the set temperature until the bathroom is restarted. In addition to storing the time T, when the temperature in the bathroom reaches the set temperature, the injection of the hot water H / W from each hot water jet nozzle 5 is temporarily stopped, and then the stored time T until the resumption of heating is stored. By performing such control as to repeat the ON / OFF of the injection of the hot water H / W from the hot water jet nozzle, even if the hot water H / W is not jetted from each of the hot water jet nozzles 5, heating is performed. Since the timing of resuming heating can be predicted from the temperature rising speed of the hot water H / W at the time, the fluctuation of the bath room temperature during the temperature control is small, and the temperature control in the bathroom can be performed accurately.
[0020]
6 and 7 show another embodiment of the temperature control state in the mist sauna apparatus according to the present invention, in which the hot water H · W injected from each of the hot water jet nozzles 5 in the bathroom is used. During the stop of the heating, the temperature measurement by the thermistor 6 becomes inaccurate, so that the temperature is measured while performing the injection of the hot water H · W from each hot water jet nozzle 5 at every predetermined time t until the heating is resumed, The temperature of the bath room temperature is controlled by stopping after heating to a predetermined set temperature (OFF point). In this case, as shown in FIG. ) when is low, injection time t ₀ becomes longer, as shown in FIG. 7, when the temperature (outside air temperature) is higher in the air a in the bathroom, the injection time t ₀ becomes short.
[0021]
That is, when the temperature in the bathroom reaches the set temperature, the injection of the hot water H · W from each hot water jet nozzle 5 is stopped, and then each hot water jet nozzle at regular time intervals t until heating is resumed. with repeated oN · OFF of ejection of heating hot water H · W from 5, when the temperature in the bathroom injection time t ₀ of the heating hot water H · W per the predetermined time t has reached the set temperature, each By controlling the injection of the hot water H · W from the hot water jet nozzle 5 to be stopped, it is possible to accurately control the inside of the bathroom while the hot water H · W is being injected at regular time intervals t until the heating is resumed. Since the temperature can be measured, the temperature of the bath room can be accurately controlled.
[0022]
【The invention's effect】
As is apparent from the above description, the present invention raises the temperature of the bathroom from a constant temperature equal to or lower than the set temperature to the set temperature during the initial heating in which the bathroom is heated to the set temperature by injecting the hot water from the hot water jet nozzle. When the temperature in the bathroom reaches the set temperature, the injection of the hot water from the hot water ejection nozzle is temporarily stopped, and then the stored time until the restart of heating is read from the hot water injection nozzle. Since the control for repeating the ON / OFF of the injection of the hot water is performed, the timing of the resumption of the heating can be easily predicted from the temperature rising speed of the hot water during the heating. Fluctuations can be reduced, and thereby temperature control in the bathroom can be performed accurately.
[0023]
Further, in claim 2, when the temperature in the bathroom reaches the set temperature, the injection of the hot water from the hot water jet nozzle is stopped, and thereafter, the injection of the hot water from the hot water jet nozzle at regular intervals until the heating is resumed. While repeating the above, at the time when the interior of the bathroom reaches the set temperature, the injection time of the hot water every fixed time until the resumption of the heating is controlled so as to stop the injection of the hot water from the hot water jet nozzle. Therefore, it is possible to accurately measure the temperature in the bathroom while the hot water is being sprayed at regular intervals until the heating is restarted.
[0024]
In addition, since there is no need to install a separate temperature detecting device or a fan unit on the bathroom side as before, the installation and wiring can be performed easily, and the cost of the entire apparatus can be reduced and maintenance can be reduced. Improvement can be achieved.
