Hereinafter, a plurality of embodiments will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the site | part substantially common in each embodiment, and the detailed description is abbreviate | omitted.
(First embodiment)
Hereinafter, the dryer according to the first embodiment will be described with reference to FIGS. 1 and 2. In the present embodiment, a so-called drum type laundry dryer is assumed as the dryer.

  As shown in FIG. 1 (A), a washing / drying machine 1 has a bottomed cylindrical water tank 3 having an opening on the right side in the drawing, that is, the front side of the washing / drying machine 1, and a housing 2 constituting the outer shell. A rotating tank 4 is provided. The rotating tub 4 is rotationally driven around the rotating shaft Lc by a motor 5 as a driving means while being accommodated in the water tub 3. In the case of the present embodiment, the rotation axis Lc is an inclined type inclined from the installation surface.

  This washing / drying machine 1 has a selection course such as a washing operation, a rinsing operation, and a drying operation from an operation panel (not shown), the type of laundry such as a blanket and cotton, the amount of the laundry that can estimate the weight or weight of the laundry, Various information for operating the washing / drying machine 1 such as a required time in each operation is set. Then, a washing operation such as a washing operation is performed based on the set information. In addition to the information received from the operation panel, for example, a temperature sensor that detects the temperature of air flowing through the circulation path, a humidity sensor that detects humidity, a weight sensor that detects the weight of the loaded laundry, the rotating tub 4, A configuration may be employed in which a vibration sensor that detects vibrations of the washing / drying machine 1 and an outside air temperature sensor that detects the outside air temperature are provided, and the washing / drying machine 1 is controlled based on information acquired from these sensors.

  In the water tank 3, a supply port 3 a for supplying air into the water tank 3 is formed on the side facing the bottom 4 c of the rotating tank 4, that is, on the back side of the rotating tank 4. The water tank 3 is formed with an exhaust port 3b for exhausting the air in the water tank 3 at the top. In the case of this embodiment, the supply port 3a and the exhaust port 3b are formed in the water tank 3 so as to be positioned above the upper limit line W in which water is stored during the washing operation and the rinsing operation.

  The supply port 3a is connected via a piping member 7 to a circulation part 6 having heating means such as a heater, heating and dehumidifying means such as a heat pump, and air blowing means such as a fan for circulating air. Further, the exhaust port is connected to the circulation portion 6 via a piping member 7. When the circulation unit 6 is driven by the control unit 8, the air heated and dehumidified in the circulation unit 6, that is, the air for drying the laundry is indicated by an arrow Y1 in FIG. To the water tank 3.

  More specifically, the air heated, dehumidified and blown by the circulation unit 6 is supplied into the water tank 3 from the supply port 3a, and after taking in moisture from laundry such as clothes in the rotating tank 4, It exhausts from the exhaust port 3b. And after heating and dehumidifying again in the circulation part 6, it is supplied to the water tank 3. That is, the air circulates in the circulation path formed including the water tank 3 and the rotating tank 4 in the housing 2. For this reason, in this embodiment, air is not directly supplied into the rotary tub 4 from the supply port. Note that a filter (not shown) for removing lint such as lint is not provided in this circulation path. In the case of the heater type, a mechanism for bringing the air and the water flow into contact with each other is provided in order to remove moisture in the air.

  The rotating tub 4 has a plurality of holes 4 a communicating with the inside of the rotating tub 4 in the cylindrical portion. Via this hole 4a, water used during washing and rinsing operations and air used during drying operations are supplied and discharged. Moreover, the rotating tank 4 is provided with a plurality of baffles 4b on the inner surface side thereof. The laundry stored in the rotating tub 4 is stirred by the baffle 4b.

  The rotating tub 4 is rotationally driven while being supported by a drum support 4d as a supporting member provided on the back side of the bottom portion 4c. As shown in FIG. 1B, the rotating tub 4 is surrounded by a drum support 4d and an edge of the bottom 4c at the bottom portion 4c, and, for example, six holes 4e communicating with the rotating tub 4 are formed. . The hole 4e is covered with a mesh member 4f to prevent the clothing from entering. For this reason, when the rotating tub 4 rotates, the air supplied toward the rotating tub 4 from the supply port 3a is finally blocked through the hole 4e while being partially blocked by the air flow created by the rotating drum support 4d. Therefore, it is supplied into the rotary tank 4.

  By the way, the water | moisture content which comes out of the laundry at the time of drying operation is contained in the air which circulates through a circulation path, and is exhausted from the rotating tank 4 and the water tank 3. Therefore, in order to remove moisture more efficiently, that is, in order to improve drying efficiency, it is desirable that the air is exhausted in a state containing more moisture. Therefore, in the present embodiment, the drying efficiency is improved by paying attention to the rotation direction of the rotating tub 4.

  In the case of the washing / drying machine 1, as shown in FIG. 1A, the supply port 3 a is provided on the back side of the rotating tub 4, and the exhaust port 3 b is positioned on the front side of the cylindrical portion of the rotating tub 4. Is provided. Further, as shown in FIG. 2A, the supply port 3a is located slightly to the left of the axis C of the rotation axis Lc in the front view when the rotation axis Lc of the rotating tub 4 is viewed from the front side. The exhaust port 3b is located slightly to the left in the drawing with respect to the axis C of the rotation axis Lc.

  Now, in order to contain more moisture in the air, it is only necessary to make the path when the air flows from the supply port 3a to the exhaust port 3b longer. In this case, the laundry accommodated in the rotating tub 4 is agitated according to the rotation and moves in the rotating tub 4. And the air in the rotating tub 4 is also stirred by the laundry and the baffle 4b. Therefore, an air flow toward the rotation direction of the rotary tank 4 is formed in the rotary tank 4. In particular, in the case of a structure in which air is supplied into the water tank 3 as in the present embodiment, in other words, a structure in which air is not directly supplied into the rotating tank 4, the air flow in the rotating tank 4 is in the rotational direction. Will match.

At this time, it can be determined as follows which rotation direction the rotation tank 4 is rotationally driven.
First, as shown in FIG. 2A, first, a first imaginary line L1 that is a virtual line connecting the rotation axis Lc of the rotating tub 4 and the supply port 3a, and the rotation axis Lc and the exhaust port 3b are connected. A second virtual line L2 that is a virtual line to be connected is set. In the present embodiment, the first virtual line L1 is set as a line that generally passes through the center of the supply port 3a, and the second virtual line L2 is set as a line that passes through the center of the exhaust port 3b. At this time, when the first imaginary line L1 is rotated around the rotation axis Lc to the second imaginary line L2, two rotation directions, clockwise and counterclockwise, are assumed.

At this time, the rotation angle when rotating the first virtual line L1 clockwise to the second virtual line L2 is θ1, and the rotation angle when rotating counterclockwise is θ2. Each rotation angle is the minimum value when the target virtual line is rotated in the respective rotation direction, that is, in the case of rotating the first virtual line L1 in less than one rotation in this embodiment, the rotation axis. This is the rotation angle when first overlapping the second imaginary line L2 when viewed from the Lc direction. In the washing / drying machine 1, the ratio of rotating the rotating tub 4 in the rotation direction of θ1 and θ2 in the rotation direction of the larger rotation angle (counterclockwise in the case of FIG. 2A) is small. The rotation rate is set to be larger than the rate of rotationally driving the rotary tub in the direction of rotation on the side (clockwise in the case of FIG. 2A).

  At this time, when the rotating tub 4 is driven to rotate clockwise (clockwise) indicated by an arrow R1 in FIG. 2 (A), as indicated by an arrow Y2 in FIGS. 2 (B) and (C), An air flow having a relatively short path length from the supply port 3a to the exhaust port 3b is formed.

  On the other hand, when the rotary tub 4 is rotated counterclockwise (counterclockwise) indicated by the arrow R2 in FIG. 2A, it is indicated by the arrow Y3 in FIGS. 2B and 2C. Thus, an air flow having a relatively long path length from the supply port 3a to the exhaust port 3b is formed. That is, the drying air stays in the rotary tank 4 for a longer time.

  That is, in the case of the washer / dryer 1 having the configuration shown in FIG. 1, when the air is circulated by the circulation unit 6, that is, when the drying operation is executed in the present embodiment, the rotating tub 4 is rotated counterclockwise (leftward). By rotating the rotation around the air, the path length of the air from the supply port 3a to the exhaust port 3b can be relatively increased, and the contact time between the laundry and the air can be increased. Therefore, more water can be included in the air.

  However, during the drying operation, in order to prevent tangling of the laundry, it is necessary to rotate the rotating tub 4 not only in one direction but also in the reverse direction. Therefore, in the present embodiment, the rate at which the rotating tub 4 is rotated counterclockwise during the drying operation is set larger than the rate at which the rotating tub 4 is rotated clockwise. This ratio may be set according to the type of laundry, but in the case of this embodiment, for example, the rotating tub 4 is driven to rotate 90 seconds counterclockwise, and then rotated clockwise for 30 seconds. By rotating the counterclockwise rotation time relatively long, such as driving again and then rotating counterclockwise for 90 seconds, the rate of rotating the rotating tank 4 counterclockwise is rotated clockwise. It is larger than the driving rate.

According to the washing / drying machine 1 of 1st Embodiment demonstrated above, there can exist the following effects.
When the laundry dryer 1 as a dryer circulates air by the circulation unit 6, it is a virtual connection between the rotation axis Lc of the rotating tub 4 and the supply port 3a when viewed from the direction of the rotation axis Lc of the rotating tub 4. Two rotation directions assumed when the first imaginary line L1 which is a straight line is rotated to the second imaginary line L2 which is a imaginary line connecting the rotation axis Lc and the exhaust port 3b (FIG. 2A). Of the rotation direction of the rotating tub 4 in the rotation direction on the side with the larger rotation angle (θ2 side) in the rotation direction on the side with the smaller rotation angle (θ1 side). The tank 4 is set to be larger than the rate of rotationally driving the tank 4.

  When the rotating tub 4 is rotationally driven in the rotation direction on the side with the larger rotation angle (θ2 side), the path length through which the drying air flows is set in the rotation direction on the side with the smaller rotation angle (θ1 side). Is relatively longer than when the is driven to rotate. Therefore, when the rotary tub 4 is rotationally driven in the rotation direction on the side with the larger rotation angle (θ2 side), the contact time between the laundry and the air becomes longer, and more moisture is contained in the air and exhausted. The Thereby, laundry, such as clothing, can be dried more efficiently, and drying efficiency can be improved.

Moreover, since it controls so that the ratio which rotationally drives the rotation tank 4 is enlarged, naturally the rotation tank 4 is rotationally driven also to a reverse direction. Thereby, compared with the case where it rotationally drives only to one direction, the tangle of a laundry can be suppressed.
Therefore, tangling of the laundry can be prevented and drying efficiency can be improved.

  In the case of the washing / drying machine 1, the washing tub 1 is provided with a water tank 3 for storing water, and the rotating tub 4 has a bottomed cylindrical shape having an opening for taking in and out the laundry, and at least a cylindrical portion communicates with the inside of the rotating tub 4. Are arranged in the water tank 3 in a state where the holes 4a are formed. And the supply port 3a is located in the bottom part 4c side of the rotation tank 4, and is formed in the water tank 3. FIG. That is, the air supplied from the supply port 3a may be somewhat hindered from flowing directly into the rotating tub 4. Therefore, drying efficiency can be improved by forming the path | route which can make a water | moisture content more contained in the rotation tank 4 as mentioned above.

(Second Embodiment)
Hereinafter, the dryer according to the second embodiment will be described with reference to FIGS. 3 to 6. In the second embodiment, several specific examples in which the positional relationship between the supply port and the exhaust port and the direction of the rotation axis Lc are different from the first embodiment will be described. In the second embodiment, illustration of the piping member 7 and the like is omitted.

<Specific example 1>
In the case of the washer / dryer 10 of the first specific example, as shown in FIG. 3A, both the supply port 3 a and the exhaust port 3 b are provided on the bottom of the water tank 3, that is, on the back side of the rotary tank 4. The supply port 3a is located below the axis C of the rotation axis Lc in the front view as viewed from the direction of the rotation axis Lc, and the exhaust port 3b is located above the axis C of the rotation axis. Is located.

  Thus, even if the positional relationship between the supply port 3a and the exhaust port 3b is different from that in the first embodiment, the first virtual line that is a virtual line connecting the rotation axis Lc of the rotating tub 4 and the supply port 3a. Of the two rotation directions assumed when the line L1 is rotated to the second virtual line L2, which is a virtual line connecting the rotation axis Lc and the exhaust port 3b, the side with the larger rotation angle, that is, FIG. ), The ratio of rotationally driving the rotating tub 4 in the clockwise direction of rotation indicated by the arrow R3 is larger than the ratio of rotationally driving the rotating tub 4 in the direction of small rotation angle, that is, counterclockwise. By doing so, similarly to the first embodiment, it is possible to form an air flow that allows more water to be contained in the air. Therefore, laundry such as clothes can be efficiently dried, and drying efficiency can be improved.

<Specific example 2>
In the case of the washing / drying machine 20 of the specific example 2, as shown in FIG. 3B, both the supply port 3a and the exhaust port 3b are provided at positions facing the cylindrical portion of the water tank 3, that is, the cylindrical portion of the rotating tub 4. ing. And the supply port 3a and the exhaust port 3b are located above the axial center C of the rotating shaft Lc in the front view seen from the rotating shaft Lc direction similarly to 1st Embodiment. However, in the specific example 2, the supply port 3a is located above the exhaust port 3b.

  Even in such a positional relationship, a virtual line connecting the rotation axis Lc and the exhaust port 3b is connected to the first virtual line L1 that is a virtual line connecting the rotation axis Lc of the rotating tank 4 and the supply port 3a. Of the two rotation directions assumed when rotating to the second imaginary line L2, which is a line, in the case of the rotation angle side, that is, in the case of FIG. 3B, in the counterclockwise rotation direction indicated by the arrow R4. By making the rate of rotationally driving the rotating tub 4 larger than the rate of rotationally driving the rotating tub 4 in the direction of the smaller rotation angle, that is, in the clockwise rotation direction, as in the first embodiment, more moisture can be obtained. An air flow that can be included in the air can be formed. Therefore, laundry such as clothes can be efficiently dried, and drying efficiency can be improved.

<Specific example 3>
In the case of the washing / drying machine 30 of the specific example 3, as illustrated in FIG. 4, the rotation axis Lc is horizontal with the installation surface. That is, in the washing / drying machine 30, the rotating tub 4 is rotationally driven in a direction parallel to the installation surface, unlike the first embodiment. The supply port 3a and the exhaust port 3b are both in the same positional relationship as in the first embodiment.

  Even in the washing / drying machine 30 in which the rotation axis Lc is parallel to the installation surface, the ratio of rotationally driving the rotary tub 4 in the rotation direction on the side where the rotation angle is large, as in the first embodiment, By making it larger than the ratio of rotationally driving the rotary tub 4 in the rotational direction with the smaller rotation angle, it is possible to form an air flow that allows more moisture to be included in the air. Therefore, laundry such as clothes can be efficiently dried, and drying efficiency can be improved.

<Specific Example 4>
In the case of the washing / drying machine 40 of the specific example 4, as shown in FIG. 5, the supply port 3a is formed on the rotating shaft Lc.

  In this case, since the air supplied from the supply port 3a is assumed to be relatively warmer than the air containing moisture exhausted from the exhaust port 3b, it is assumed that the air flows vertically upward. Therefore, assuming the third imaginary line L3, which is a virtual line extending vertically upward from the rotation axis Lc of the rotating tub 4 when viewed from the direction of the rotating axis Lc of the rotating tub 4, the third imaginary line L3 is rotated. Of the two rotation directions assumed when rotating to the second imaginary line L2 around the axis Lc, the ratio of rotationally driving the rotary tub 4 in the rotation direction on the side with the larger rotation angle (θ4 side in FIG. 5) The rotation rate of the rotary tub 4 is set to be larger than the rate of rotationally driving the rotary tub 4 in the rotation direction on the side where the rotation angle is small (θ3 side in FIG. 5). Thereby, the flow of the air which can make more water | moisture content in air can be formed in the rotating tank 4, and a drying efficiency can be improved.

  In addition, when the exhaust port 3b is located on the rotation axis Lc, among the two rotation directions assumed when rotating the third virtual line L3 to the first virtual line L1 around the rotation axis Lc, By making the ratio of rotationally driving the rotary tub 4 in the rotational direction with the larger rotation angle larger than the ratio of rotationally driving the rotary tub 4 in the rotational direction with the smaller rotational angle, more moisture is transferred to the air. The flow of air that can be included can be formed in the rotating tub 4, and the drying efficiency can be improved.

<Specific Example 5>
In the case of the washer / dryer 50 of Example 5, as shown in FIG. 6, both the supply port 3a and the exhaust port 3b are located on a straight line passing through the axis C of the rotation axis Lc when viewed from the rotation axis Lc. Is formed. That is, the supply port 3a and the exhaust port 3b have a point-symmetrical positional relationship with the axis C as the center. In this case, since the first imaginary line L1 and the second imaginary line L2 are substantially in a straight line, the rotation angle is substantially equal regardless of which direction the rotary tub 4 is rotationally driven.

  Therefore, in the case of such a configuration, a third virtual line L3 that is a virtual line extending vertically upward from the rotation axis Lc of the rotating tub 4 in a state viewed from the direction of the rotating axis Lc of the rotating tub 4 is assumed. Of the two rotation directions assumed when the first imaginary line L1 is rotated about the rotation axis Lc to the third imaginary line L3, the arrow R7 indicates that the rotation angle is larger, that is, the configuration shown in FIG. The rotation rate of the rotating tub 4 in the counterclockwise rotation direction in which the rotation angle shown is θ6 is the clockwise rotation in which the rotation angle indicated by the arrow R6 is θ5 if the rotation angle is smaller, that is, in the configuration of FIG. It is made larger than the ratio which rotationally drives the rotating tub 4 in the rotation direction.

  As a result, the drying air that tends to go vertically upward forms a flow in the rotating tub 4 in a direction in which the path length to the exhaust port 3b becomes longer, that is, in a direction in which the contact time between the laundry and the air becomes longer. Is done. Therefore, more moisture is contained in the air and exhausted, and laundry such as clothes can be efficiently dried.

  Although FIG. 6 shows an example in which the supply port 3a and the exhaust port 3b are formed in point-symmetric positions, the supply port 3a and the exhaust port 3b are in the same direction, that is, from the axis C to the supply port 3a. The same applies to the case where the exhaust port 3b is formed on the extension of the above, and the case where the supply port 3a is formed on the extension line from the axis C to the exhaust port 3b. In this case, the supply port 3a and the exhaust port 3b are formed so as to be shifted in the direction of the rotation axis Lc, that is, in the front-rear direction of the washing / drying machine 50, but when viewed from the direction of the rotation axis Lc, the two match. It seems to be formed in the direction.

(Other embodiments)
The present invention is not limited to the one exemplified in the above-described embodiment, and can be arbitrarily modified or expanded without departing from the scope thereof.

  In each embodiment, the ratio at which the rotating tank 4 is rotationally driven is fixedly set. However, when the drying operation is performed, the rotating tank 4 is rotated in the rotation direction with the larger rotation angle as the drying operation proceeds. The driving ratio may be increased. In the initial stage of the drying operation, the laundry contains a lot of moisture, while the moisture contained in the laundry decreases as the drying operation proceeds. For this reason, when operating at the same rate, the amount of water contained and discharged per unit time is relatively large at the beginning of the drying operation, and decreases relatively as the drying operation proceeds. It is assumed that Therefore, when the drying operation has progressed, the rate of rotationally driving the rotating tub 4 in the rotational direction with the larger rotation angle than the initial stage of the drying operation is increased so that more moisture can be discharged. Thereby, in a state where the drying operation proceeds and the amount of moisture contained in the laundry is reduced, the time during which the laundry is exposed to the air is controlled to be longer, and moisture is easily contained in the air. Therefore, drying efficiency can be improved.

  Moreover, when performing dry operation, you may determine the kind of laundry and change the ratio which rotationally drives the rotation tank 4 to the rotation direction of a rotation angle side according to the determined kind of laundry. For example, it is considered that fibers such as cotton and hemp are more likely to contain moisture than chemical fibers such as polyester. Moreover, even if it is the same fiber, it is possible that the amount of moisture contained in thick clothing and thin clothing is different. Therefore, as described in the first embodiment, based on the settings input from the operation panel and the information detected by various sensors, for example, the information on the amount of clothes, the quality of the clothes, the outside temperature, etc., the rotating tub 4 You may change the ratio which rotates. Even with such a configuration, moisture can be easily contained in the air, and drying efficiency can be improved.

  In addition, not only increasing the rate of rotating the rotating tub 4 in the rotational direction on the side with the larger rotation angle, but also determining that the clothes are likely to get tangled, the rotating tub in the direction of rotation with the larger rotation angle. You may make the ratio which rotationally drives 4 approach the ratio which rotationally drives the rotation tank 4 in the rotation direction of the side with a small rotation angle.

In each embodiment, although the laundry dryer provided with the washing function was illustrated as a dryer, what was not provided with the washing function may be used.
In each embodiment, air for drying is assumed. For example, when a sterilization means for including a sterilizing agent or a picometer-sized sterilizing ion in the air is provided in the circulation path, the sterilizing air is circulated. In addition, the ratio of rotationally driving the rotating tub 4 in the rotational direction on the side with the larger rotational angle may be close to the ratio of rotationally driving the rotational tub 4 in the rotational direction on the side with the smaller rotational angle. Disinfectants, disinfecting ions, etc. are contained in the air and exhibit a disinfecting action when in contact with the laundry, but by increasing the rate at which the rotating tub 4 is rotationally driven in the rotation direction on the side with the larger rotation angle It is considered that the contact time between the air and the laundry becomes longer and the sterilization effect can be enhanced. Of course, the present invention can also be applied to the case where only the sterilization operation is performed without the washing operation and the drying operation.

  Each embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
