Embodiment 1
Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 8.

(System overview)
FIG. 1 is an explanatory view showing an appearance of a pet air conditioning system according to a first embodiment of the present invention. As illustrated in (a) and (b) of FIG. 1, the pet air conditioning system 1 includes a portable air conditioner 10 and an air duct 20 capable of transmitting a wind conditioned by at least the portable air conditioner 10 (air passage And a mat portion 30 provided with a breathable pet seat 31.

  The portable air conditioner 10 incorporates an air conditioning unit 40 that switches between cooling operation and heating operation in a housing, and is configured to be lightweight and compact so that the user can easily carry it. The portable air conditioner 10 takes in the outside air, and sends out the air adjusted to the set temperature by the air conditioning unit 40 from the air duct 20 to the inside of the mat unit 30.

  The mat portion 30 includes the pet seat surface 31 on which the pet sits and reclines, and the ridge portion 32 which protrudes around the pet seat surface 31 and serves as a pet pillow. The ridges 32 may or may not be present. The pet seat 31 has such a breathability that a gentle and slightly felt air flow 50 is generated on the pet seat 31 by cold air or warm air fed into the mat portion 30. Moreover, as shown to (a) of FIG. 1, several ventilation openings 33, such as slit shape or circular shape, may be formed in the inner surface of the protruding part 32. As shown in FIG. Furthermore, the cover 60 (cover part) which accommodates the whole of the mat | matte part 30 may be provided.

  As described above, the mat unit 30 and the portable air conditioner 10 are independent of each other, and the temperature of the mat unit 30 is adjusted by the air-conditioned wind. Therefore, since it is not necessary to provide the mat portion 30 with an electronic component, an electrical trouble does not occur in the mat portion 30. Therefore, the pet air conditioning system 1 can be provided with high safety and reliability. Furthermore, since the pet seat 31 can partially cool or warm the body's thermoregulatory site (abdomen, meat ball, etc.) of the pet, the energy cost can be kept low compared to a mode in which the pet's entire living room is thermostated. be able to.

  Further, since the mat portion 30 is independent, the mat portion 30 can be replaced with another mat portion. For example, when replacing a pet, only the mat portion 30 can be changed according to the size of the pet. Furthermore, when the mat unit 30 can not withstand use, it can be easily replaced with a new mat unit. Therefore, the fact that the mat portion 30 can be replaced is advantageous in cost because it is not necessary to newly adjust the pet air conditioning system 1.

  Furthermore, since the mat unit 30 is separated from the portable air conditioner 10, the noise generated by the compressor or the fan of the portable air conditioner 10 is reduced in the mat unit 30 and sounds like a pet. Therefore, the comfort of the mat portion 30 is not disturbed by the noise.

(Supplementary to the composition of the mat part)
(A) of FIG. 2 is explanatory drawing which shows the other form of a mat | matte part, FIG. 2: (b) is explanatory drawing which shows the further another form of a mat | matte part. As shown to (a) of FIG. 2, the mat | matte part 30A is equipped with the base part 70 provided with cushioning property and air permeability, and the cover 60A (cover part) which accommodates the base part 70. As shown in FIG. The base portion 70 is formed, for example, by intertwining resilient resin fibers, and the shape thereof is, for example, a flat cylindrical shape, an elliptical cylindrical shape, a rectangular solid shape, or the like. Air tightness is given to the side and bottom of the base portion 70. For example, the side surfaces and the bottom surface of the base portion 70 are covered with an airtight film. At a part of the side surface of the base portion 70, a vent 71 (connection port) for opening the air-conditioned wind into the interior of the base portion 70 is opened. Since the upper surface of the base portion 70 has sufficient air permeability, the wind sent into the inside of the base portion 70 through the air vent 71 gently flows upward from the upper surface.

  The cover 60A has a shape corresponding to the shape of the base portion 70, and has a volume capable of accommodating the base portion 70. The side or bottom of the cover 60A is opened and closed by a bonding member such as a chuck. On the side surface of the cover 60A, a vent 61 (connection port) communicating with the vent 70 of the base portion 70 by aligning and facing is formed. The air vent 61 has a structure to which the air duct 20 is connected.

  Instead of the mat portion 30A, a mat portion 30B shown in (b) of FIG. 2 can be employed. The mat portion 30B is provided with a cover 60B (cover portion) in addition to the base portion 70. The main difference between the cover 60B and the cover 60A is that a plurality of vent holes 61 are formed on the side surface of the cover 60B. In addition, the point by which the protruding part 32B which serves as a pet's pillow is provided in a part of upper surface of the cover 60B is also a secondary difference. According to the above main differences, the vent 61 connected to the air duct 20 can be selected, and the orientation of the mat portion 30B with respect to the air duct 20 can be changed variously. Therefore, the user can select the vent hole 61 in which the direction of the mat portion 30B is optimal according to the situation of the place where the mat portion 30B is to be placed.

  The air vent 61 not connected to the air duct 20 is closed by a cap or the like so that the air does not leak out.

  For example, cotton can be adopted as the material of the above covers 60, 60A, 60B, and a toweling with cushioning properties can be adopted as the state of the fabric. In addition, the fabric may be a brushed fabric so that pet's nails and the like do not get caught on the fabric. In any event, it is preferable to employ a material suitable to create a gentle, slightly felt airflow 50. In the mat portions 30A, 30B, since the base portion 70 and the covers 60A, 60B can be separated, the covers 60A, 60B can be removed from the mat portions 30A, 30B and washed. Also, the base 70 taken out of the mats 30A, 30B can be dried or disinfected in sunlight.

(External configuration of air conditioner)
FIG. 3 is a perspective view showing the appearance of a pet air conditioning system 1A provided with the portable air conditioner 10A, the portable air conditioner 10A corresponding to the air duct 20 and the mat portion 30, the air duct 20A and the mat portion 30A. is there. As shown in FIG. 3, the portable air conditioner 10A includes a case 11 (housing), an air outlet 12 is formed on the front of the case 11, and an air duct 20A is connected to the air outlet 12. . The air outlet 12 sends cold air during cooling operation and sends hot air during heating operation.

  Further, an exhaust port 13 is formed on the top surface of the case 11. The exhaust port 13 exhausts warm air during cooling operation and exhausts cold air during heating operation. The exhaust port 13 may or may not be separated by partitioning into an exhaust port (warm exhaust port) for the warm air and an exhaust port (cold exhaust port) for the cold air. When not separated, one end side of the exhaust port 13 in the longitudinal direction mainly discharges the warm air, and the other end side mainly discharges the cold air.

  In addition, the exhaust port 13 may be always open, or the lid 14 having a half size of the opening area of the exhaust port 13 may be provided. The lid 14 may be a lid that slides in the longitudinal direction along the top surface. In this case, the lid 14 closes the hot exhaust port during the heating operation and slides to a position where the cold exhaust port is opened, and slides during the cooling operation to the position where the hot exhaust port is opened and the cold exhaust port is closed. As a result, the opening area of the exhaust port 13 can be reduced, and dust and safety considerations can be enhanced. Furthermore, a mesh covering the exhaust port 13 may be attached. Preferably, the mesh has a roughness that does not impede ventilation.

  A first suction port 15 serving as an outside air suction port of an evaporator 41 (FIG. 4), which will be described later, is formed on one of two side surfaces facing each other across the front of the case 11 in which the air blowing port 12 is formed. Moreover, the 2nd suction port 16 used as the open air suction port of the condenser 45 (FIG. 4) mentioned later is formed in the other of the said two side surfaces.

  Below the air outlet 12, a drain tank 17 for storing drain water generated during cooling operation is detachably fitted to the portable air conditioner 10A. However, a more preferable embodiment in which the drain tank 17 is not provided in the portable air conditioner 10A but provided below the mat portion 30A will be described later.

(Internal configuration of air conditioner)
FIG. 4 is a perspective view showing the portable air conditioner 10A with the case 11 and the drain tank 17 removed. FIG. 5 is a perspective view showing the portable air conditioner 10A with the case 11 and the four-way valve 48 removed. FIG. 6 is a perspective view showing a state in which the evaporator 41 and the condenser 45 are further removed from the state of FIG.

  The air conditioning unit 40 is accommodated in the case 11. The air conditioning unit 40 includes an evaporation unit 40A and a condensation unit 40B. However, the roles of the evaporation unit 40A and the condensation unit 40B are switched according to the cooling operation and the heating operation by the operation of the four-way valve 48. FIG. 4 shows the evaporator 40A and the condenser 40B that play a role in the cooling operation mode. Therefore, in the heating operation mode, the evaporating unit 40A is changed to the condensing unit 40A, and the condensing unit 40B is changed to the evaporating unit 40B. In the following, the operation of the air conditioning unit 40 during the cooling operation will be mainly described, and the operation of the air conditioning unit 40 during the heating operation will be described later in Embodiment 4 and later.

  As shown in FIG. 5, a compressor 49 is provided below the air conditioning unit 40. The compressor 49 causes the refrigerant vaporized by the evaporation unit 40A in the cooling operation mode or the evaporation unit 40B in the heating operation mode to transition from the low temperature low pressure state to the high temperature high pressure state.

  The evaporator 40A includes an evaporator 41, a first fan casing 42, and a sirocco fan 43 (first fan). The sirocco fan 43 sucks outside air from the first suction port 15 through the evaporator 41 and sends cold air to the air blowing port 12 during cooling operation. The cold air is guided to the air outlet 12 by the first fan casing 42. Therefore, as also shown in FIG. 6, the first fan casing 42 is formed in a cylindrical shape so that a moldable member surrounds the outer periphery of the sirocco fan 43. The one end portion and the other end portion of the cylindrical strip-shaped member are in close proximity to each other at a predetermined interval, and extend toward the air outlet 12 so that the first outlet E of the air flow (first (Air flow outlet) is formed.

  The condensing part 40B is also comprised including the said condenser 45, the 2nd fan casing 46, and the sirocco fan 47 (2nd fan) similarly to the evaporation part 40A. The sirocco fan 47 sucks outside air from the second suction port 16 through the condenser 45 and sends warm air to the exhaust port 13 during cooling operation. The warm air is guided to the exhaust port 13 by the second fan casing 46. Therefore, as shown also in FIG. 6, the second fan casing 46 is formed in a cylindrical shape so that a moldable member surrounds the outer periphery of the sirocco fan 47. The one end portion and the other end portion of the belt-like member formed in a cylindrical shape are in a state in which they approach each other at a predetermined interval, and form a second outlet F of the air flow (a second air flow outlet).

  The air outlet 12 is formed on the front of the case 11, and the air outlet 13 is formed on the top surface of the case 11. Therefore, the first outlet E of the evaporator 40A and the second outlet F of the condenser 40B are provided. The direction of discharge of each air flow is 90 degrees different. The sirocco fans 43 and 47 have the same rotation axis, obtain driving force from the same motor, and simultaneously rotate.

(Configuration of switch)
A switch group is disposed on the top surface or the back surface of the case 11. The switch group includes a changeover switch capable of switching and selecting the operation mode (cooling operation, heating operation, dehumidifying operation, blowing operation, etc.) of the portable type air conditioner 10A, and a power on / off switch. Each switch is locked by a long press of the user. This is to prevent a pet or infant from inadvertently touching the switch to cause a malfunction. You may attach the cover which covers a switch group so that a pet or a baby etc. may not touch a switch carelessly.

(Charged particle generator)
The pet air conditioning system 1 may be provided with a generator of charged particles having at least one of a sterilizing action and a deodorizing action. As such a generator, for example, a generator that generates cluster ions in which water molecules in the air are gathered around each of positive ions and negative ions can be mentioned. Briefly explaining the method of generating cluster ions, positive and negative voltages are applied to the discharge electrode to ionize water molecules and oxygen molecules in the air to form positive ions of hydrogen and negative ions of oxygen. As a result, water molecules in the air gather around the ions to form stable cluster ions <H ⁺ (H ₂ O) _n and O 2 ⁻ (H ₂ O) _n > with a long lifetime. Such cluster ions (charged particles) generate OH radicals when attached to bacteria, viruses, odorous substances and the like, and exert a bactericidal action and a deodorizing action.

  Therefore, by providing the generator for charged particles in the pet air conditioning system 1, the effect of suppressing ammonia odor or body odor derived from the pet, for example, the reduction effect of canine valvovirus or other suspended bacteria etc. which dogs are easily infected etc. Is obtained. As a result, it is possible to create a comfortable space for the pet and the owner.

  An air flow is necessary to widely distribute the charged particles. Therefore, a site where the charged particles can be transported by air flow is suitable as the installation site of the generator. For example, at least one of the areas C3 and C4 shown in FIG. 4 is suitable as an installation site of the generator. The area C3 is located in the second fan casing 46 which forms a flow passage leading to the exhaust port 13, and the charged particles are discharged from the exhaust port 13 to the outside of the portable air conditioner 10 together with the exhaust. The area C4 is located in the first fan casing 42 which forms a flow passage leading to the air outlet 12, and charged particles are fed from the air outlet 12 through the air duct 20A into the mat portion 30A. The charged particles fed into the mat portion 30A spread in the mat portion 30A to exert the bactericidal action and the deodorizing action, and also diffuse from the upper surface of the mat portion 30A to act on the pet, so the bactericidal action on the pet And deodorizing effect.

  Furthermore, the generator can be provided in the area C2 shown in FIG. The area C2 is located in the path of the air flow in the mat portion 30A. However, the area C2 is not the best position because it leads to the provision of the electronic parts and the electrical wiring in the mat portion 30A.

(Pet detection sensor)
The pet is not always resting on the mat portion 30A all the time, and repeats moving away from the mat portion 30A and moving around and returning again to the mat portion 30A. Then, the cost performance can be improved by changing the operation performance of the air conditioning unit 40 depending on whether or not the pet is on the mat unit 30A.

  Therefore, the pet air conditioning system 1 may be provided with a pet detection sensor. As the installation site of the pet detection sensor, at least one of the areas C1 and C2 shown in FIG. 3 can be mentioned. The area C1 is located on the side of the portable air conditioner 10A facing the mat portion 30A, and a pet detection sensor provided on the area C1 is preferably a sensor capable of detecting a pet from a distant place. As such a sensor, for example, an infrared sensor, an ultrasonic sensor or a camera can be adopted. The area C2 is located on the upper surface of the mat portion 30A, unlike the position where the generator is provided. Since the area C2 is a part in contact with or close to a pet, a pressure sensor or a temperature sensor can be adopted as a pet detection sensor provided there. The pressure sensor detects the weight of the pet applied to the mat portion 30A. The temperature sensor may be provided at one position in the central portion of the mat portion 30A, or may be provided at two positions in the central portion and the peripheral portion of the mat portion 30A. When temperature sensors are provided at two locations, it is possible to more accurately detect that the pet is on the mat portion 30A when there is a temperature difference between the two temperature sensors (temperature at the central portion> temperature at the peripheral portion). .

(Operation control based on pet detection)
Next, control for changing the driving performance of the air conditioning unit 40 will be described based on the output of the pet detection sensor.

  FIG. 7 is a block diagram showing the configuration of a control system 80 that executes such control. The control system 80 includes a sensor 81 (first sensor), a control unit 82, a timer 83 (timer unit), a memory 84, and the air conditioning unit 40. The sensor 81 is a pet detection sensor as described above. The control unit 82 is configured of, for example, a CPU that organically controls the control system 80 in accordance with a program stored in the memory 84. The timer 83 counts in response to an instruction of the control unit 82, and outputs the result to the control unit 82.

  FIG. 8 is a flowchart showing a procedure of processing in which the control unit 82 changes the operation performance of the air conditioning unit 40 based on the output of the sensor 81. When the power supply of the portable air conditioner 10A is turned on (step 1; abbreviated as S1 below), the control unit 82 starts the operation of the air conditioning unit 40 (S2). The operation mode such as the cooling operation or the heating operation is already designated in S1.

  The control unit 82 causes the timer 83 to start timing at the same time as starting the operation of the air conditioning unit 40, and when the predetermined time t1 has elapsed (S3), the control unit 82 has the sensor 81 detect a pet on the mat unit 30A. It is determined whether the detection result of being present is output (S4). If the determination result in S4 is NO, the control unit 82 recognizes that the absence time of the pet is long to some extent, and the air conditioning unit 40 is switched from the normal operation mode to the energy saving operation mode in which the energy consumption decreases. It instructs switching (S5).

  The timing of the timer 83 started from S3 is continued after the execution of S5. Then, when the absence time of the pet is a long time, that is, when the predetermined time t2 (> t1) is reached (S6), the control unit 82 detects the detection result that the pet is on the mat portion 30A. It is determined whether it is output (S7). If the determination result of S7 is NO, the control unit 82 turns off the portable air conditioner 10A (S8). In this case, since the control by the control unit 82 ends, the pet air conditioning system 1A does not operate unless the user turns on the portable air conditioner 10A at S1. Therefore, the pet air conditioning system 1A may be activated when the pet returns to the mat unit 30A again after being absent for a long time. For that purpose, the control unit 82 may instruct the air conditioning unit 40 to start operation at S8 and return the process to S2.

  On the other hand, if the determination result in S4 is YES, that is, the pet continues to stay in the mat portion 30A or is absent for a short time, and the pet returns to the mat portion 30A when the predetermined time t1 elapses. In this case, the control unit 82 returns the process to S3 and continues the normal operation mode being executed by the air conditioning unit 40 as it is. Then, the control unit 82 repeats the determination of the detection result by the sensor 81 (the process of S4) in a cycle of a predetermined time t1. When the determination result in S7 is YES, the pet is absent from the mat unit 30A when the predetermined time t1 elapses, and returns again to the mat unit 30A when the predetermined time t2 elapses. Therefore, the control unit 82 cancels the energy saving operation mode and returns to the normal operation mode (S9), returns the process to S3 and continues to execute the process from S4.

Second Embodiment
Embodiment 2 of the present invention will be described with reference to FIGS. 9 to 11. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

(Treatment of drain water)
In the cooling operation mode, the refrigerant decompressed by the expansion valve to a low temperature cools the evaporator, so the water vapor in the air condenses in the evaporator and water droplets are generated. As the cooling operation continues, water droplets continue to be generated and become drain water, so it is necessary to treat drain water. Although the portable air conditioner 10A shown in FIG. 3 includes the drain tank 17 for temporarily storing drain water, it is preferable not to include the drain tank 17 in order to miniaturize the portable air conditioner 10A.

  FIG. 9 is a perspective view showing a pet air conditioning system 1B in which a method of providing a drain tank is devised. The pet air conditioning system 1B includes a portable air conditioner 10B, which is smaller than the portable air conditioner 10A by omitting the drain tank, and a mat unit 30A placed on the drain tank 90 (water storage container). . That is, the drain tank 90 is disposed in contact with the bottom surface of the mat portion 30A.

  A water receiving pipe 91 and a drain pipe 92 are provided on the side surfaces of the drain tank 90, respectively. The water receiving pipe 91 receives drain water generated by the portable air conditioner 10B and guides the drain water into the drain tank 90. The drain pipe 92 is used to drain drain water stored in the drain tank 90. The drainage pipe 92 is provided with an opening and closing member such as a cock that can open the drainage pipe 92 at the time of drainage and can usually close the drainage pipe 92. It is preferable that the water receiving pipe 91 also be provided with an open / close member such as a faucet that can close the water receiving pipe 91 at the time of drainage and normally can open the water receiving pipe 91. Further, the water receiving pipe 91 and the drainage portion of the portable air conditioner 10B are connected via a drain hose 93. A one-shot coupler or the like can be employed as a connecting device between the water receiving pipe 91 and the drain hose 93.

  With the above configuration, drain water generated by the portable air conditioner 10B during the cooling operation is stored in the drain tank 90 from the portable air conditioner 10B through the drain hose 93. Since the drain tank 90 is disposed in contact with the bottom of the mat portion 30A, the installation space of the mat portion 30A is the installation space of the drain tank 90. Therefore, the portable air conditioner 10B can be miniaturized, and the space saving of the pet air conditioning system 1B can also be realized.

  Further, by changing the height of the drain tank 90, the capacity of the drain tank 90 can be increased or decreased without changing the installation space of the pet air conditioning system 1B. When the height of the drain tank 90 is increased to increase the capacity, the continuous operation time of the cooling can be lengthened.

  Furthermore, since the cold drain water generated during the cooling operation is stored immediately below the mat portion 30A, the drain tank 90 acts as a cooling source for the mat portion. As a result, the energy cost of the cooling operation can be saved.

  In the conventional machine in which the Peltier element is provided in the mat portion, there is a possibility that the pet hair and the like may be clogged as foreign matter in the passage where the condensation water generated in the Peltier element is stored in the container, and the condensation water may overflow. However, in the present embodiment, drain water is stored in the drain tank 90 from the portable air conditioner 10B through the drain hose 93, so there is no risk that body hair of a pet relaxing on the mat portion 30A will be mixed as foreign matter.

(Modified example 1 of drain tank)
FIG. 10 is an explanatory view showing a configuration of a drain tank 90-1 replacing the drain tank 90. As shown in FIG. As shown in (a) and (b) of FIG. 10, the drain tank 90 has a structure divided into two layers of an upper layer portion 90A and a lower layer portion 90B. The upper layer portion 90A and the lower layer portion 90B are divided by a partition 94. An overflow pipe 95 (communication structure) is provided in a part of the peripheral portion of the partition 94, and the upper layer portion 90A and the lower layer portion 90B communicate with each other in the overflow pipe 95. The overflow pipe 95 rises from the surface of the partition 94, and the height thereof is set to less than the height of the upper layer portion 90A. The water receiving pipe 91 is attached to the side wall of the upper layer portion 90A, and the drainage pipe 92 is attached to the side wall of the lower layer portion 90B.

  In the above configuration, drain water flowing from the water receiving pipe 91 is first stored in the upper layer portion 90A. When the upper layer portion 90A is full of drain water, drain water overflows in the overflow pipe 95 and is stored in the lower layer portion 90B, as shown by arrows in (a) and (b) of FIG. When the lower layer portion 90B is also full, the operation of the portable air conditioner 10B is turned off, and drain water stored in the drain tank 90 is drained from the drain pipe 92 or both the water receiving pipe 91 and the drain pipe 92 Do.

  According to the above configuration, since the cold drain water is stored in the upper layer portion 90A close to the bottom surface of the mat portion 30A, the drain tank 90-1 is more effective than the drain tank 90 in the function as the cooling source for the mat portion 30A. It will strengthen. Further, since the drain water stored in the upper layer 90A overflows to the lower layer 90B, the drain water of the upper layer 90A is always replaced with cold drain water. Therefore, the effect of keeping the bottom surface of the mat portion 30A at a low temperature is enhanced. From this point of view, it is preferable that the height of the overflow pipe 95 be as close as possible to the height of the upper layer portion 90A because the water surface when the upper layer portion 90A is full is closer to the bottom surface of the mat portion 30A. In addition, setting the capacity of the upper layer 90A smaller than the capacity of the lower layer 90B accelerates the filling of the upper layer 90A and also accelerates the time for drain water in the upper layer 90A to be replaced with new drain water. This is preferable because it enhances the cooling effect on

  The reason why it is preferable to provide the overflow pipe 95 in the peripheral portion rather than the central portion of the partition 94 is because the peripheral portion is less likely to bear the weight of the pet than the central portion. When the overflow pipe 95 is provided at the central portion of the partition 94, the upper surface of the drain tank 90-1 may be pushed down by the weight of the pet, and the upper end of the overflow pipe 95 may be blocked by the upper surface of the drain tank 90-1. In this case, since the overflow is prevented, an erroneous detection occurs that the drain tank 90-1 becomes full of water although the upper part 90A is only full of water. Therefore, when the overflow pipe 95 is provided on the peripheral edge of the partition 94, the occurrence of such erroneous detection can be easily prevented.

(Modified example 2 of drain tank)
FIG. 11 is an explanatory view showing a modification of the mat portion and the drain tank. First, with reference to (c) of Drawing 11, other modifications of a drain tank are explained. The drain tank 90-2 includes a main tank 96 (main capacity portion) and a sub tank 97 (sub capacity portion). Although the main tank 96 and the sub tank 97 are integrated, they are not in communication but separated. A flow passage 98 (passage portion) is formed on the upper surface of the sub tank 97. The flow path 98 communicates with the water receiving pipe 91 and also communicates with the main tank 96. On the other hand, an opening 97a is formed on the upper surface of the sub tank 97, and an opening and closing mechanism 99 such as a pivoting or sliding lid for opening and closing the communication between the sub tank 97 and the flow path 98 is provided in the opening 97a. . The open / close mechanism 99 is opened only when drain water is drained from the drain tank 90-2, and brings the sub tank 97 and the flow path 98 into communication. That is, during the cooling operation, the open / close mechanism 99 is in the closed state.

  According to the above configuration, drain water generated in the portable air conditioner 10B during the cooling operation flows into the flow path 98 and then flows from the flow path 98 into the main tank 96. The opening 97 a is closed by the opening / closing mechanism 99 at least during the cooling operation, so drain water does not flow into the sub tank 97 during the cooling operation. When the main tank 96 is eventually filled with drain water and the opening / closing mechanism 99 closing the opening 97a is opened, a relatively small amount of drain water stored in the drain hose 93 shown in FIG. Into the sub tank 97 (cavity portion). By doing this, when drain water is drained from the drain tank 90-2, drain water stored in the middle route between the portable air conditioner 10B and the drain tank 90-2 is around the portable air conditioner 10B. It is possible to avoid the trouble of spilling out.

  As the opening and closing mechanism 99, a lid attached with rubber packing can be adopted. When the lid is pivotable, a pivot shaft attached with a manual lever is provided on the upper surface of the sub tank 97, and the user swings the lid up and down around the pivot shaft by rotating the manual lever. Can be opened and closed.

(Modified example of mat part)
Next, with reference to FIG. 11, a mat portion 30B replacing the mat portion 30A will be described. (A)-(c) of FIG. 11 has shown the mat | matte part 30B which represented typically the cross-sectional structure of the inside of a base part. The mat portion 30B has a cushion member 34 inside, and further includes an annular air duct 35 shown in (d) of FIG. 11 so as to surround the cushion member 34. The outer surface of the mat portion 30B is covered with a breathable cover 36 (cover portion) as already described in the first embodiment. The cushion member 34 may be, for example, an assembly of a flexible and elastic hollow resin thin tube.

  A plurality of holes 37 aligned along the entire circumference are formed on the inner annular side surface of the air duct 35. Further, a connecting pipe 38 connected to the air blowing duct 20 or 20A is provided in a protruding manner on a part of the outer side annular surface of the air duct 35.

  According to the above configuration, the wind having passed through the air blowing duct 20 or 20A is fed into the air flow pipe 35 from the connection pipe 38, and as shown by the arrows in (b) and (d) of FIG. And blows out from the plurality of holes 37 toward the center of the mat portion 30B. A void is randomly present in the entire cushion member 34, and only the upper surface of the mat portion 30B is breathable. For this reason, the air flow blown out of the plurality of holes 37 gently rises through the air gap of the cushion member 34 and through the cover 36 on the upper surface of the mat portion 30B.

Third Embodiment
A third embodiment of the present invention will be described with reference to FIG. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

(Drain water full detection)
As described in the second embodiment, drain water generated by continuation of the cooling operation is stored in the drain tank, but the drain tank becomes full of water as time passes. It is preferable to automatically detect this full state and notify the user that the drain water disposal time has come. Furthermore, as described above, it is preferable not to provide the mat portion with an electronic component such as a sensor for detecting a full state of the drain tank, but to provide the portable air conditioner in order to avoid the occurrence of electrical troubles.

(Configuration of full water detection)
FIG. 12 is an explanatory view showing a pet air conditioning system 1C in which a configuration for full water detection is devised. The pet air conditioning system 1C includes a portable air conditioner 10C and a drain tank 90 (90-1, 90-2). The portable air conditioner 10C and the drain tank 90 are connected by the drain hose 93. Under the evaporation unit 40A built in the portable air conditioner 10C, a tray-like water receiving unit 110 that receives drain water generated by the evaporator 41, for example, is provided. A drainage port is formed at the bottom of the water receiving portion 110, so the drainage port and the drain tank 90 are connected via the drain hose 93. Furthermore, in the vicinity of the water receiving unit 110, a sensor 111 (second sensor) that detects the full water of the water receiving unit 110 is provided.

  As the sensor 111, for example, a water gauge that is attached to the inner wall of the water receiving unit 110 and detects the water level of drain water stored in the water receiving unit 110 can be employed. An output signal when the sensor 111 detects full water is sent to, for example, the control unit 82 described in FIG. 7. In response to this, the control unit 82 causes the notification unit provided in the air conditioning unit 40 to execute a notification operation (sound, sound, light, image, or the like).

  According to the above configuration, when the drain tank 90 is full of water, the drain water not contained in the drain tank 90 is stored in the drain hose 93, and finally stored in the water receiving unit 110. That is, for a while after the drain tank 90 is full of water, the water receiving unit 110 becomes full of water. The fullness of water in the water receiving unit 110 is detected by the sensor 111 and notified to the user. In this way, the portable air conditioner 10C can detect that the drain tank 90 is full.

  In addition, even when the drain hose 93 is blocked due to contamination, bending or the like, the sensor 111 can detect that the water receiving portion 110 is full. Therefore, it is possible to prevent the occurrence of the trouble that the drain water overflows into the portable air conditioner 10C due to the blockage of the drain hose 93. Furthermore, since the capacity of the water receiving unit 110 may be extremely small compared to the capacity of the drain tank 90, the portable air conditioner 10C can be miniaturized as in the portable air conditioner 10B.

Embodiment 4
The fourth embodiment of the present invention will be described with reference to FIGS. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

  In the portable air conditioner 10A of the first embodiment, the four-way valve 48 switches the refrigerant circuit (heat pump circuit) in the cooling operation mode and the refrigerant circuit (heat pump circuit) in the heating operation mode. However, if the four-way valve 48 can be omitted, the number of parts can be reduced, and there is no need to design a complicated heat pump circuit, so that downsizing and cost reduction of the portable air conditioner 10A can be realized. it can.

  FIG. 13 is an explanatory view showing a configuration example of a portable air conditioner which realizes the omission of the four-way valve 48. As shown in FIG. As shown in FIG. 5, the portable air conditioner according to the present embodiment does not include the four-way valve 48, and includes the first fan casing 42 and the second fan casing 46 described above. However, as shown in FIG. 13, each of the fan casings 42 and 46 can be integrally rotated about the rotation axis 44 of the sirocco fans 43 and 47 by a predetermined angle (for example, 90 degrees). The second state after rotation can be taken.

  The first state corresponds to the cooling operation mode, and the second state corresponds to the heating operation mode. Each fan casing 42 and 46 automatically takes the first state when the user instructs the portable air conditioner to perform the cooling operation, and automatically takes the second state when the heating operation is instructed.

  FIG. 14 is a perspective view schematically showing the configuration of the case 11D of the portable air conditioner. As shown in (a) and (b) of FIG. 14, an air outlet 18L (first air outlet) for delivering cold air corresponding to the first state is provided on one side surface of the case 11D. In addition, a blower 18R (a second blower for delivering warm air corresponding to the above-described second state to a position different from the blower 18L in the direction of the blowing air, for example, the other side located opposite to the one side Mouth) is provided. In addition, an exhaust port 19 is provided at a position where the direction of the blowing air is different from the air blowing ports 18L and 18R, for example, the top surface of the case 11D.

  In the above configuration, in the first state (cooling operation mode), cold air is sent from the air outlet 18L, and the mat portion 30 is connected to the air outlet 20L via the air duct 20 ((a) in FIG. 14). Can be sent. That is, as shown in FIG. 5 and FIG. 13, the air cooled by the evaporator 41 is sent as cold air from the first outlet E of the first fan casing 42 by the sirocco fan 43 and is aligned with the first outlet E It is sent out from the blowout port 18L. Thereby, the mat portion 30 is cooled.

  Also, at the same time, the air warmed by the condenser 45 is delivered as hot air from the second outlet F of the second fan casing 46 by the sirocco fan 47, and the outlet 19 aligned with the second outlet F Discharged from

  On the other hand, in the second state (heating operation mode), the fan casing 20 is rotated integrally by a predetermined angle to send warm air from the air outlet 18R, and the air duct 20 replaced with the air outlet 18R. It can be fed into the mat unit 30 via ((b) in FIG. 14). That is, as shown in FIG. 13, the air warmed by the condenser 45 is sent as warm air from the second outlet F of the second fan casing 46 by the sirocco fan 47. At this time, since the second outlet F is rotated by a predetermined angle from the first state, the second outlet F is delivered from the air outlet 18R aligned with the second outlet F. Thereby, the mat unit 30 is warmed.

  At the same time, the cold air passing through the evaporator 41 is delivered by the sirocco fan 43 as a cold air from the first outlet E of the first fan casing 42. At this time, since the first outlet E is also rotated from the first state by the same predetermined angle, it is discharged from the exhaust port 19 aligned with the first outlet E.

  Since the blower 18L and the blower 18R have different blower directions (for example, 180 degrees), the user is directed to the portable air conditioner and the mat portion in the cooling operation mode and the heating operation mode. It will change.

Fifth Embodiment
Embodiment 5 of the present invention will be described with reference to FIGS. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

The air duct 22E and the exhaust duct 23E are opposed in the diameter direction of the duct switching valve 100. The air duct 22E and the exhaust duct 23E do not move even if the duct switching valve 100 rotates. Further, in the blower duct 22E, a blower port 12E for blowing out cold air or warm air to the outside along a diameter direction (substantially horizontal direction) of the duct switching valve 100 is formed. In accordance with the air outlet 12E, an air outlet (not shown) is also formed in the case 11E. Furthermore, an exhaust port 13E is formed on the flat top surface of the case 11E in accordance with the exhaust duct 23E.

  The air duct 22E and the exhaust duct 23E are shared by both the cooling operation and the heating operation, and their roles are not switched depending on the operation mode. Therefore, in the portable air conditioner 10E, as in the fourth embodiment, it does not take time and effort to replace the air duct according to the operation mode or change the direction of the portable air conditioner and the mat portion.

And are formed. The first ventilation passage 102 and the second ventilation passage 103 are formed to sandwich the exhaust passage 101.

  More specifically, the first air passage 102 and the second air passage 103 are formed at a predetermined distance from each other on the circular upper surface when the duct switching valve 100 is viewed in a plan view, and at a position near the outer periphery. ing. The exhaust passage 101 is provided with an exhaust port 101a formed on the outer periphery of the lower surface. That is, the exhaust port 101 a is opened at a position between the opening of the first air passage 102 and the opening of the second air passage 103 in the lower surface. Further, the exhaust passage 101 is provided with an exhaust outlet 101b opened on the upper surface at a position diagonally opposed to the exhaust receiving port 101a across the center of the cylindrical shape. Furthermore, the exhaust passage 101 is provided with an inclined passage 101c that obliquely connects the exhaust receiving port 101a and the exhaust outlet 101b.

  According to the above configuration, cold air or warm air exhausted through the exhaust passage 101 is discharged at a position away from the first air passage 102 and the second air passage 103 on the upper surface of the duct switching valve 100. become. From the viewpoint of achieving this object, the configuration of the exhaust passage 101 is not limited to the configuration shown in FIG. That is, how is the layout of the air duct 22E and the exhaust duct 23E described above in the case 11E based on the inclination angle with respect to the lower surface or upper surface of the inclined path 101c, the length of the inclined path 101c and the position of the exhaust outlet 101b in the upper surface? It should be decided according to Therefore, the ramp 101c may be linear or curved.

  The opening angle (center angle; θ shown in FIG. 18) formed by the center of the exhaust port 101a and the center of the opening of the first ventilation path 102 with respect to the center of the lower surface of the air duct 22E The opening angle (center angle; θ shown in FIG. 18) formed by the center and the center of the opening of the second air passage 103 is preferably equal to the switching between the cold air passage and the warm air passage. This point will be described in detail later.

(Description of the figure showing switching of air flow path)
With reference to FIGS. 17 to 19, the switching mechanism of the air flow path, that is, the switching of the cool air path for sending cold air to the mat unit 30 and the warm air path for sending warm air to the mat unit 30 will be described. FIG. 17 is an explanatory view including a partial perspective view showing formation of a cold air passage and a warm air passage, wherein (a) shows the formation of a cold air passage in the cooling operation mode, and (b) shows the warm air flow in the heating operation mode It shows the formation of a passage. FIG. 18 is an explanatory view showing the formation of a cold air passage in the cooling operation mode, and (a) is a schematic plan view showing the positional relationship between the duct switching valve and the air duct 22E and the exhaust duct 23E. These are arrow sectional drawing which follows the BB 'line shown to (a). FIG. 19 is an explanatory view showing formation of a warm air path in the heating operation mode, and (a) is a schematic plan view showing the positional relationship between the duct switching valve and the air duct 22E and the exhaust duct 23E (b ) Is an arrow sectional view taken along the line CC ′ shown in (a).

(Outline of air flow path switching operation)
As shown in (a) and (b) of FIG. 17, the duct switching valve 100 is rotated about its central axis into a position relative to the evaporation portion and the condensation portion disposed on the lower side, Switching between the first rotational position and the second rotational position. The first rotational position is selected for the cooling mode of operation, and the second rotational position is selected for the heating mode of operation.

  More specifically, as shown in FIG. 17A, at the first rotation position, the first air passage 102 is positioned directly above the first fan casing 42E of the evaporation section, and the second fan of the condensation section is positioned. The exhaust passage 101 is aligned directly above the casing 46E and the duct 21E. Further, as shown in FIG. 17B, at the second rotational position, the exhaust passage 101 is positioned immediately above the first fan casing 42E of the evaporation section, and the second fan casing 46E and the duct 21E of the condensation section are The second air passage 103 is positioned immediately above.

  Thus, the cold air passage in the cooling operation mode and the front half of the hot air exhaust passage (hereinafter referred to as a warm exhaust passage) are formed, and the warm air passage and the cold air exhaust passage in the heating operation mode (hereinafter, The first half of the cold exhaust path is formed.

(Formation of air flow path in cooling operation mode)
First, the configurations of the air duct 22E and the exhaust duct 23E described with reference to FIG. 15 will be supplemented. As shown in (a) of FIG. 18, the housing constituting the air duct 22E has a lateral width wider than the distance between the opening of the first air passage 102 and the exhaust port 101a on the lower surface of the duct switching valve 100. There is. And when it sees from the front in the state which stood up the ventilation duct 22E, the horizontal width of the ventilation opening 12E opened to the front of the ventilation duct 22E is narrower than the horizontal width of the said housing. The angle (central angle) between the center of the opening of the first ventilation passage 102 on the lower surface and the center of the exhaust port 101 a with respect to the center of the lower surface of the duct switching valve 100 is θ.

  The width of the housing of the exhaust duct 23E is wide enough to cover the range of the angle θ because the exhaust outlet 101b opened on the upper surface of the duct switching valve rotates in the range of the angle θ. As a result, the width of the housing of air duct 22E and the width of the housing of exhaust duct 23E may be set equal.

  When the duct switching valve 100 is in the first rotational position in the cooling operation mode as shown in (a) of FIG. 18, as shown in (b) of FIG. And the exhaust duct 23E is located above the exhaust outlet 101b. As a result, a cold air flow path is formed such that the first fan casing 42E of the evaporation portion → the first air flow path 102 → the air flow duct 22E → the air flow port 12E. On the other hand, a warm exhaust path is formed as the second fan casing 46E of the condensation portion → duct 21E → exhaust path 101 → exhaust duct 23E → exhaust port 13E.

(Formation of air flow path in heating operation mode)
As shown in FIG. 19A, in the heating operation mode, when the duct switching valve 100 is viewed from above, the second rotation in which the duct switching valve 100 rotates counterclockwise from the first rotation position by the angle θ Be in position. When the duct switching valve 100 is in the second rotation position, as shown in FIG. 19B, the air duct 22E is located on the second air passage 103, and the exhaust duct 23E is located on the exhaust outlet 101b. . As a result, a warm air passage is formed as the second fan casing 46E of the condensing portion → the duct 21E → the second air passage 103 → the air duct 22E → the air outlet 12E. On the other hand, there is formed a cold exhaust path such as the first fan casing 42E of the evaporation section → exhaust path 101 → exhaust duct 23E → exhaust port 13E.

And a mat portion (30, 30A or 30B) connected to the passage (the air duct 20 or 20A) and provided with the air-permeable pet seat (31).

  According to the above configuration, the mat unit on which the pet rests and the portable air conditioner are independent of each other, and the temperature of the mat unit is adjusted by the air conditioned by the portable air conditioner. Therefore, it is not necessary to provide an electronic component in the mat portion. As a result, since generation | occurrence | production of the electrical trouble which may occur in the structure which provided the electronic component in the mat | mat part can be avoided, the highly reliable pet air conditioning system can be provided.

  Furthermore, by adjusting the temperature of the pet seat, the pet seat can partially cool or heat the pet's thermoregulatory site (abdomen, meat balls, etc.), making it comfortable for the pet to rest on the mat Can be given. Moreover, in this form, energy cost can be held down compared with the form which temperature-controls the whole pet room.

  In the portable air conditioner, a heat pump circuit including a condenser, an evaporator, and a fan is integrally configured, and can be carried by a user.

  The pet air conditioning system according to aspect 2 of the present invention is characterized in that, in the above aspect 1, the mat portion is attachable to and detachable from the air flow path of the portable air conditioner.

In addition, since the mat units of different sizes can be attached to the portable air conditioner, it is sufficient to change only the mat units according to the size of the pet when replacing a pet. Furthermore, when the mat portion can not withstand use, it can be easily replaced with a new mat portion. Therefore, the fact that the mat portion can be replaced is advantageous in cost because it is not necessary to newly adjust the entire pet air conditioning system.

  The pet air conditioning system according to aspect 3 of the present invention is characterized in that in the above aspect 1 or 2, a generator of charged particles having at least one of a sterilizing action and a deodorizing action is provided at least in the air passage. .

  According to the above configuration, the charged particles having the bactericidal action and / or the deodorizing action are delivered from the generator at least through the air duct to the mat portion by the conditioned wind. As a result, it is possible to exert an effect in removing odors derived from pets attached to the mat portion, or germs or viruses tending to propagate in the mat portion and the periphery thereof. As a result, it is possible to provide a pet air conditioning system suitable for keeping a pet in the residence area of the owner (user).

  The pet air conditioning system according to aspect 4 of the present invention is the pet air conditioner according to any one of aspects 1 to 3, further comprising: a first sensor 81 for detecting whether or not a pet is present in the mat portion; According to the timer unit (83) for measuring the absence time of the vehicle, and the operation mode of the portable air conditioner according to the absence time measured by the timer unit, from the operation mode including the normal mode, the energy saving mode and the operation off And a control unit (82) to select.

  According to the above configuration, the operation mode is selected in accordance with the condition of whether or not a pet is present in the mat unit, or how long it has not been present. Therefore, it is possible to reduce the waste of energy required for operating the pet air conditioning system and to optimize the energy cost. For example, the control unit selects the normal mode according to the output of the first sensor indicating that the pet unit is present in the mat unit, and the first sensor and the timer unit indicate that the pet unit is not present in the mat unit for a short time Then, the energy saving mode can be selected. Further, the control unit can select the operation off in the situation where the first sensor and the timer unit indicate that the pet is not present in the mat for a long time.

  In the pet air conditioning system according to aspect 5 of the present invention, in any of the above aspects 1 to 4, the mat portion has a cushioning and breathable base portion (70), and the base portion is removable. A cover portion (cover 36, 60, 60A or 60B) that accommodates and is breathable is provided, and airtightness is imparted to the surface of the base portion except the upper surface corresponding to the pet seat surface. It is characterized by

  According to the above configuration, since the mat portion can be divided into the base portion and the cover portion, the user cleans the base portion and the cover portion according to the respective materials of the base portion and the cover portion. May be given (washing, bleaching or sun-drying etc).

  Further, the upper surface of the base portion corresponding to the pet seat surface has air permeability, and the surface other than the upper surface has air tightness, so the wind fed into the mat portion makes the pet seat surface efficient. Can be chilled or warmed. As a result, the pet seat surface can easily reach the optimum temperature in a short time.

  In the pet air conditioning system according to aspect 6 of the present invention, in any of the above aspects 1 to 5, the mat portion is provided with a connection port (61) connected to the air flow path, and the connection port These are characterized in that they are provided at a plurality of places so that the direction of the mat portion with respect to the air blowing path can be changed.

  The pet air conditioning system according to aspect 7 of the present invention is the water storage container (90, 90-1 or any of the above aspects 1 to 6) that receives and stores drain water generated during cooling operation by the portable air conditioner 90-2), wherein the water storage container is disposed in contact with the bottom surface of the mat portion.

  According to the above configuration, drain water generated during cooling operation is sent from the portable air conditioner to the water storage container and stored in the water storage container. Since the water storage container is disposed in contact with the bottom surface of the mat portion, it is not necessary to provide the water storage container in the portable air conditioner, and it can also serve as the installation space of the water storage container and the installation space of the mat portion. This contributes to downsizing of the portable air conditioner and space saving of the pet air conditioning system.

  Moreover, since the installation space of the mat portion can be used as the installation space of the water storage container, it is easy to determine the height of the water storage container so as to increase the capacity of the water storage container. If the capacity of the water storage container is increased, the continuous operation time of the cooling can be extended.

  Furthermore, since the cold drain water generated during the cooling operation is stored immediately below the mat portion, the water storage container acts as a cooling source for the mat portion. As a result, the energy cost of the cooling operation can be saved.

  In the pet air conditioning system according to aspect 8 of the present invention, in the above aspect 7, the water storage container (90-1) has a two-layer structure of an upper layer (90A) and a lower layer (90B), and the drain water The upper layer and the lower layer are provided with a communication structure (overflow pipe 95) in which drain water stored in the upper layer overflows to the lower layer.

  According to the above configuration, the upper layer of the water storage container is closer to the bottom surface of the mat portion than the lower layer. Since cold drain water is stored in such upper layer, the function of the water storage container as the above-mentioned cooling source for the mat portion can be strengthened. Also, because drain water stored in the upper layer overflows to the lower layer, drain water in the upper layer is always replaced with cold drain water. For this reason, the effect of keeping the bottom surface of the mat portion at a low temperature is enhanced.

  The pet air conditioning system according to aspect 9 of the present invention is the pet air conditioning system according to aspect 7, wherein the water storage container (90-2) has a relatively small capacity to the main capacity portion (main tank 96) having a relatively large capacity. The sub-volume portion is separated into a volume portion (sub-tank 97), and the sub-volume portion is provided with a passage portion (flow path 98) to which the drain water is sent and in communication with the main volume portion, and an opening portion (97a And an opening / closing mechanism (99) for opening / closing the opening, wherein the opening is closed by the opening / closing mechanism at least during the cooling operation.

  According to the above configuration, drain water generated in the portable type air conditioner during the cooling operation is sent to the passage portion of the sub-capacity portion, and then flows from the passage portion to the main capacity portion. Since the opening is closed by the opening / closing mechanism at least during the cooling operation, drain water does not flow into the sub-volume portion during the cooling operation.

  When the main capacity section is filled with drain water, it is necessary to discard the drain water. In this case, a relatively small amount of drain water stored in the water channel on the way between the portable air conditioner and the water storage container can be poured into the sub-volume portion by opening the opening / closing mechanism that closed the opening. . By doing this, when separating the water storage container from the portable air conditioner in order to discard drain water from the water storage container, drain water stored in the waterway between the portable air conditioner and the water storage container is spilled It is possible to avoid problems that occur.

  The pet air conditioning system according to aspect 10 of the present invention is the petty water receiving system according to any one of aspects 7 to 9, wherein the drain water generated in the evaporation unit (40A) built in the portable air conditioner (10A) is received. A portion (110) is provided in the portable type air conditioner, and the outlet of the water receiving portion and the drain water receiving port in the water storage container are connected via a pipe (drain hose 93), the water receiving portion In the vicinity of the unit, a second sensor (sensor 111) for detecting the fullness of the water receiving unit is provided.

  According to the above configuration, since the electronic component including the second sensor and the electrical wiring is provided in the portable air conditioner, it is not necessary to provide the mat component with the electronic component. Therefore, it is possible to prevent a failure of the system caused by the pet scratching or scratching the electronic component, or the occurrence of an accident such as an electric shock or a short circuit.

  Further, even when the pipe connecting the water receiving portion and the water storage container is blocked due to foreign matter mixing, bending or the like, the second sensor can detect that the water receiving portion is full. Therefore, it is possible to prevent in advance the occurrence of the trouble that the drain water overflows into the portable air conditioner due to the blockage of the pipe.

In the pet air conditioning system according to aspect 11 of the present invention, in any one of aspects 1 to 4, the portable air conditioner is

(4) An exhaust port (19) provided in the housing at a position where the direction of the air flow is further different from the first air outlet and the second air outlet,
(5) A first fan casing (a first fan casing (the first outlet E) that encloses the periphery of the first fan (sirocco fan 43) provided in the evaporation section and from which the air flow sent out by the first fan blows 42) and
(6) A second fan casing (a second fan casing (a second outlet F) that encloses the periphery of a second fan (sirocco fan 47) provided in the condensing section and from which the air flow sent out by the second fan blows out (second outlet F) 46) and,
(7) At the time of cooling operation, the first air flow outlet communicates with the first air outlet, and the second air flow outlet communicates with the air outlet,
(8) At the time of heating operation, the first air flow outlet communicates with the exhaust port by rotating the first fan casing and the second fan casing integrally by a predetermined angle from the position at the time of the cooling operation. The air flow outlet is in communication with the second air outlet.

  According to said structure, the exhaust port provided in the housing | casing is shared so that it may play the same role called exhaust_gas | exhaustion at the time of cooling operation and heating operation. Then, when the first fan casing and the second fan casing are at the position at the time of cooling operation, cold air is sent out to the air flow path through the first air flow outlet and the first air outlet, and hot air is exhausted from the air outlet. Do. On the other hand, at the time of heating operation, the first fan casing and the second fan casing integrally rotate by a predetermined angle from the position at the time of cooling operation, whereby the warm air is blown through the second air flow outlet and the second air outlet. The air is sent out to the road, and the cold air is exhausted from the exhaust port.

  This eliminates the need for the four-way valve to switch between the cooling operation and the heating operation. Therefore, since the four-way valve is not required, the cost of the portable air conditioner can be reduced, and the space necessary for the four-way valve and the piping around it can be omitted, so the portable air conditioner can be miniaturized. it can.

It is characterized in that an air flow path switching portion (duct switching valve 100, air flow path switching portion 200 or duct switching device 300) for communicating the portion with the air blowing port is provided.

  According to the above configuration, the air outlet and the air outlet provided in the housing are shared so as to play the same role in both the cooling operation and the heating operation. Then, the air flow path switching unit sends cold air from the air blowing port to the air blowing path during cooling operation and exhausts warm air from the air discharging port during cooling operation so as to share the air outlet and the air outlet, while heating operation Hot air is sent from the air outlet to the air passage, and cold air is exhausted from the air outlet.

  As a result, only one air outlet and one air outlet may be provided in the housing, and the air conditioned during the cooling operation and the heating operation blows out from the same air outlet, so the configuration of the pet air conditioning system is simplified. It is easy to use.

  Also, in order to switch between the cooling operation and the heating operation, the four-way valve is not required. Therefore, since the four-way valve is not required, the cost of the portable air conditioner can be reduced, and the space necessary for the four-way valve and the piping around it can be omitted, so the portable air conditioner can be miniaturized. it can.
