In addition, the combrezzar 1, evaporator 2, condenser 4, blower fan 3, exhaust fan 5, cabillary 13, accumulator 16 that make up the refrigeration cycle, and the damper 9 that controls the airflow when cooling the human body or drying dishes. Servo motor to operate (not shown) and electric heater 1 to operate when drying dishes
Start from 0. The condenser 4 and the exhaust fan 5 are installed in the uppermost exhaust heat treatment section 21 of the hanging cabinet 100, and the cooling unit 23 separated from the evaporator 2 and the ventilation fan 3 is installed in the hanging cabinet 10.
It is installed at the bottom of 0. Compressor 1, accumulator 1G, capillary 13
is arranged at the rear back side of the storage 20 between the exhaust heat processing section 21 and the cooling unit 23 which are arranged above and below the hanging cabinet 100, and the condenser 4 and the evaporator 2 are connected by a refrigerant pipe. The cooling unit 23 has a structure in which a suction port 8 is opened at the bottom of the back of the hanging cabinet 100 and sucks in air, and an evaporator 2, a blower fan 3, and a damper 9 are sequentially arranged on the downstream side thereof. In addition, the air outlet 6 serves as an opening for blowing air to the human body.
00, an air blowing port 17 is installed on the lower surface of the downstream side of the blowing fan 3 as an opening for blowing air into the dish drying cabinet 30. Further, the electric heater 10 is installed in a dish drying cabinet 30 having a door 30a below the air outlet 17. Evaporator 2
A drain pan l5 for storing condensed water is installed at the bottom of the drain pan 15, and a drain hose l4 is connected from the opening on the bottom of the drain pan 15.
Condensed water is disposed of in the kitchen drain pipe or drain tank (not shown). Further, on the front of the hanging cabinet 10.0, there is a suction port 7 equipped with a filter for sucking air for cooling the human body, a suction port 11 for sucking air for exhaust heat treatment, and a suction port on the door 2Oa of the storage 20. An opening 11a is provided, and an outlet 6 for discharging cold air and an outlet 12 for discharging waste heat are opened at the top. Note that the air introduced from the suction port 11a passes through the suction port 1lb opened in the partition plate in the storage 20, and is led to the condenser 4. Further, the damper 9 has a structure in which it is rotated around a rotating shaft installed in the horizontal direction. In addition, the air outlet 6 has a louver (not shown) that allows you to freely change the direction of airflow.
is installed. When cooling the human body or drying dishes, the refrigeration cycle is activated by the compressor 1, etc., and the evaporator 2 absorbs heat.
Heat is radiated by the capacitor 4. When cooling the human body, a servo motor (not shown) is used to cool the damper 9.
is located at the position indicated by the broken line in FIG. 1, and opens the opening to the air outlet 6 and closes the opening to the dish drying cabinet 30. The air sucked in from the suction port 7 passes through the dish drying cabinet 30, then enters the cooling unit 23 from the suction port 8, and after being cooled by the evaporator 2, the air is sent from the blower fan 3 through the air outlet 6 to the upper body of the human body in the kitchen. emitted in the direction. At this time, the air in the kitchen that is sucked in through the suction ports 11 and lla at the front of the hanging cabinet 100 is heat-absorbed by the condenser 4 of the exhaust heat treatment section 21, and the exhaust fan 5 directs the air from the air outlet 12 toward the ceiling in the kitchen. is released. By the above-described operation, cold air is locally sent to the upper body of the worker (cook), and it is possible to prevent the operator from getting hot due to the heat from the gas range 41 and the like. On the other hand, the warm air generated by the exhaust heat is emitted near the ceiling and remains above the worker's head, so that it does not directly cause discomfort to the worker. Further, by operating the ventilation fan 40 installed above the gas range 4■, the warm air accumulated near the ceiling is discharged from the kitchen to the outdoors, and there is no problem of the warm air filling the kitchen. When drying dishes, the damper 9 is rotated to the position shown by the solid line in FIG. 1, closing the opening to the air outlet 6 and opening the opening to the dish drying cabinet 30. Then, the air in the dish drying cabinet 30 enters the cooling unit 23 from the above-mentioned suction port 8, is cooled and dehumidified by the evaporator 2, so the amount of moisture in the air decreases, and is also reheated by the electric heater 10. As a result, the relative humidity decreases significantly. Therefore, the evaporation of moisture adhering to the surface of the tableware is promoted by the reduction in the relative humidity of the air and heating, and effective drying is performed by the airflow hitting the tableware. Moisture that evaporates into the air adheres to the evaporator 2 and is then drained by the drain hose 14, which causes the problem of air filled with steam being released into the kitchen, like in conventional dish dryers that use only electric heaters. There isn't. Furthermore, since a dehumidification function has been added, it can provide a dish drying function in a short time and at low running costs. Moreover, by controlling the air volume of the blower fan 3 to a low level, dehumidification is further promoted and effective drying is performed. The air conditioning system, such as the operation of the refrigeration cycle when drying dishes, is basically the same as when cooling the human body, so there is no need to construct a complicated control system. Then, the exhaust heat from the exhaust heat processing section 21 is used in the same way as when cooling the human body.
It is discharged from the air outlet l2 near the kitchen ceiling,
Since the work of drying dishes is done at the end of the kitchen work after the meal is finished, workers are usually not near the dish drying cabinet, and warm air accumulates above the workers' heads, which has a negative impact on comfort. Nor. In addition, the usage times for the body cooling are different during cooking and the dish dryer is used after meals, so there are few opportunities to use them at the same time.
There are no problems with integration. Moreover, unlike human body cooling, which is used for a limited period of time, dish dryers are used throughout the year, so the operating rate of the air conditioner is greatly improved, and the built-in part of the air conditioner reduces the storage space (dead space). It rarely leads to Furthermore, since the exhaust heat processing section 21 and the cooling unit 23 are arranged vertically and are divided, it is possible to eliminate the problem of exhaust heat leaking to the cooling unit 23 and reducing its capacity. Furthermore, since the exhaust heat is released into the kitchen, there is no need for piping or exhaust duct work to the outside wall, as is the case with general indoor air conditioners. FIG. 3 shows an embodiment of an electric circuit related to the air conditioner of the present invention. The supply of electricity to the compressor 1, blower fan 3, C fan 5, servo motor 25, and electric heater 10 is controlled by operating relays RYI to RY6 in response to signals from a control unit (operation switch unit) 28 that has a built-in computer. be done. When cooling the human body, the relays of the compressor 1, blower fan 3, and exhaust fan 5 are connected. At this time, the air volume switching relay RY6 of the ventilation fan 3 can be switched freely by an air volume switching switch (not shown) of the control unit 28. When drying dishes, compressor 1, blower fan 3 (low air volume), exhaust fan 5, electric heater 10, servo motor 25
is energized. As shown in FIG. 4, when there is sufficient clearance between the top surface of the hanging cabinet 100 and the ceiling, the suction port 1 of the exhaust heat treatment section 21
A method may also be adopted in which a hole is provided on the upper surface of the hanging cabinet 100 and the exhaust heat is blown out forward from the air outlet 12. It should be noted that other structural functions are the same as those in the embodiment shown in FIG. 1, so the same reference numerals are given and the explanation thereof will be omitted. As shown in FIG. 5, the exhaust heat treatment section 21 and the compressor chamber 22 may be installed in the wall cabinet 100 above the gas range 41, which is used less frequently. in this case,
As shown in FIG. 6, at the same time as the exhaust work of ventilation [40], a ventilation port 19 communicating with the outside air may be opened in the outer wall, and exhaust heat treatment may be performed in which outside air is taken in and released to the outside air. In the embodiments shown in FIGS. 5 and 6, other structural actions are the same as those in the embodiments shown in FIGS. do. Further, as shown in FIG. 7, the suction port 11 in which the condenser 4 of the exhaust heat treatment section 21 is built and the outlet 12 in which the exhaust fan 5 is built in may be arranged on the left and right sides.

【Effect of the invention】

The present invention incorporates the cooling unit and exhaust heat processing section of an air conditioner in a hanging cabinet, adds a dish drying cabinet to the hanging cabinet, and switches the damper arranged in the cold air passage in the air conditioner. By changing the flow direction of the airflow in the cooling unit of the air conditioner and switching the air flow paths for cooling and drying dishes, the air conditioner can be installed with a minimum amount of storage space in the hanging cupboard. At the same time, the addition of a functional storage space called a dish dryer has the effect of dramatically improving the operating rate of the air conditioner.
