Abstract

PURPOSE:To decrease the attachment of oil and dust onto a heat exchanger, and to prevent the lowering of the efficiency of heat exchange by forming a blowoff port for air by a fluid element in which the direction of blowoff of air can be varied between the horizontal direction and the direction approximately vertical to the horizontal direction. CONSTITUTION:When air cooling operation, the heat exchanger 13 at the indoor side functions as an evaporator, and air sucked from a suction port by means of a blower 14 is cooled by means of the heat exchanger 13 at the indoor side, and blown out into a room from the blowoff port through a duct 16 and air-cools the kitchen. Since a valve 29 is closed in the fluid element 22 forming the blowoff port 7 at that time, upper controlling space 25 shows negative pressure, and an air current blown off from a gate 27 is blown off to an approximately vertical upper section from the blowoff port. When heating, on the other hand, the heat exchanger 13 at the indoor side serves as a condenser, and air heated is blown off from the blowoff port. In this case, the valve 29 is opened, and a hot air blown off from the gate 27 goes straight on as it is.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner suitable for air conditioning in a kitchen. .

Conventionally, general household air conditioners have been available in floor-standing types, wall-mounted types, window-mounted types, etc., but none of these types were suitable for installation in the kitchen. In other words, in the kitchen, various things are boiled, so the air conditioner inhales smoke and oil.
Not only the air filter but also the heat exchanger were covered with oil and dirt, which caused problems such as a foul odor when used for a long period of time. In order to solve these problems, it is necessary to install the air conditioner in a location relatively far away from the gas stove, etc., but in general, kitchens have various furniture, storage shelves, cupboards, etc., and it is necessary to install the air conditioner in a location that is suitable for installation. It was often difficult to find.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner suitable for air conditioning in a kitchen, which does not take up much space for installation and does not allow much oil or dust to adhere to a heat exchanger.

A kitchen air conditioner according to an embodiment of the present invention F3J1- will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a sink installed in the kitchen, and a top plate 4 on which a cooking surface 2 and a water tank 3 are formed of stainless steel is provided on the top surface. 6ij A plurality of opening/closing doors are provided in front of the sink 1. This is an underframe provided at the bottom of the sink 1. A blowout lower is provided on the lower side of the underframe 6 to blow out conditioned air, and an inlet on the other front side of the underframe 6 is provided to suck indoor air. 8 is provided. Note that this embodiment has been described considering the case where a gas stove stand is installed on the right side of the sink 1. However, if the gas stove stand is installed on the left side of the sink 1, the positions of the blower lower and the suction port 8 may be changed. Refers to something that can be reversed left and right. Reference numeral 9 denotes a partition plate that partitions a left side portion of the inside of the sink 1, and a space 10 partitioned by the partition plate 9 is further formed with a ventilation passage by partition walls 11 and 12. 130'i This is an indoor heat exchanger that forms part of a human pump type and separate type refrigeration cycle (not shown), and is housed in a part of the ventilation passage.

131L collects the dew water generated in the indoor heat exchanger 13 and guides the dew water into the drainage hose of the sink via a hose or the like. 14 sucks indoor air from the suction port 8;
This blower exchanges heat with an indoor heat exchanger 13 through a ventilation passage, and sends air that has been conditioned, such as cooling or heating, into a duct 16 through an opening 16 formed in a partition plate 9. The blower 14ij consists of a multi-blade centrifugal fan 17, a fan motor 18 for fully rotating the fan, and a fan guider 19 surrounding the multi-blade centrifugal fan 17. 2o is duct 16
This is a heat insulating material provided around the outer periphery of the This duct 16 has one end communicating with the opening 16, is disposed below the bottom plate 21 of the article storage space of the sink 1, and has the other end communicating with the blowing lower. Therefore, the article storage space of the sink 1 is not reduced by the duct 16. Next, the detailed structure of the blowout lower will be explained with reference to FIG. 4. The blowout lower includes a fluid element 22 and a left-right direction changing blade 23 provided in front of the fluid element 22. It consists of a frame body that rotatably supports this wind direction changing blade 23. The fluid element 22 includes an air outlet section 24 whose upper wall is largely curved to produce a large Coanda effect upward, upper and lower control spaces 25 and 26 located at the rear of the air outlet section 24, and further located at the rear of the air outlet section 24. A connecting part 28 to the duct 16, and a valve 29 for opening and closing communication between the upper control space 26 and the atmosphere are provided. The lower control space 26 is always in communication with the atmosphere via the hole 3o.

Next, the electric circuit of this embodiment will be explained with reference to FIG. 31 is a power source. 32 is a main switch, to which the fan motor 18 on the indoor side is connected in series. It is a 33-piece cooling/heating switch, and has a cooling side contact a and a warm side contact I. A thermostat 34 detects the indoor temperature and opens and closes contacts, and is connected in series with an outdoor fan motor 36 and a compressor motor 36 of the refrigeration cycle. 37ij is a coil of the valve 29, and is connected to the cold side contact B of the cold/heat changeover switch 33.

38 is a four-way valve that switches the refrigeration cycle from the cooling cycle to the heating cycle.

Next, the operation of the above configuration will be explained.

First, to explain the cooling operation, the heating/cooling converter switch 33 is closed to the cooling side contact a side, and the main switch 32 is closed. Accordingly, the compressor motor 36° and the outdoor fan motor 35. The fan motor 18 and coil 37 on the indoor side operate, and the valve 29 closes.

6 - In other words, the indoor heat exchanger 13 works as an evaporator, and the air sucked in from the suction port 8 by the blower 14 is cooled by the indoor heat exchanger 13 and then sent to the blowout lower via the duct 16. It is blown into the room and cools the kitchen. At this time,
In the fluid element 22 forming the blow-off lower, the valve 29 is closed, so the upper control space 26 exhibits negative pressure. Therefore, the airflow blown out from the barrier 27 flows along the earthen wall of the blowout port 24 of the fluid element 22, and is blown out almost vertically upward from the blowout lower, effectively cooling the inside of the kitchen. What's more, since this blower lower is installed near the gas stove stand, it can directly send cold air to people who are cooking over a fire in the summer, providing a local cooling effect.

Next, when heating is explained, the cooling/heating selector switch 33
By closing the heating side contact, the four-way valve 3B is activated and the refrigeration cycle is switched to the heating cycle. Therefore, the indoor heat exchanger 13ij functions as a condenser, and hot air heated here is blown out from the blower 7. In this case, since the coil 37 is not energized, the valve 29 is open and the fluid element 2
Both the upper and lower control spaces 25 and 26 of No. 2 are at atmospheric pressure. Therefore, the warm air blown from the barrier 27 travels straight and is blown out horizontally from the blow-off lower, effectively heating the inside of the kitchen.

In addition, in both cases of cooling and heating, since the suction port 8 is formed on the side far away from the gas stove stand, it is unlikely that oil or smoke will be sucked in from the suction port 8, and therefore the air filter will not become dirty or dirty. The amount of dirt on the indoor heat exchanger 13 due to oil and dust can be extremely reduced, making it suitable for use as a kitchen air conditioner.

As is clear from the description of the embodiments above, the kitchen air conditioner of the present invention is provided with a conditioned air outlet on the front side of the frame provided at the bottom of the sink, and on the other side of the front side of the frame. A suction port for sucking indoor air is provided, and an indoor heat exchanger forming a part of a refrigeration cycle is provided in the sink, and the air sucked from the suction port and heat-exchanged with the indoor heat exchanger is transferred to the air outlet. The air blower is characterized in that the air outlet is formed by a fluid element that can change the air blowing direction between a horizontal direction and a substantially vertical direction, so that the gas stove stand By placing the heater on the outlet side of the sink, smoke and oil from boiling will not be sucked in through the inlet, and oil and dust will not adhere to the air filter installed at the inlet or the indoor heat exchanger. In addition to preventing a decrease in the heat exchange efficiency of the indoor heat exchanger, it is also possible to suppress the blowing of bad odors to a large extent.Furthermore, it is possible to direct the cold air almost vertically upward from the outlet near the gas stove stand. It can blow out air, effectively cooling the kitchen, and is perfect for people who use fire near the gas stove? It blows cold air in a circular manner, making it easier to work, and when used as an air conditioner that can cool and heat, it can also blow hot air horizontally to effectively heat the kitchen. It has the effect of
