Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, there are two forms. One is the split type of internal and external units, that is, the external unit is located outdoors and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the kitchen air conditioner with split internal and external units needs to be connected through pipes, and a hole needs to be opened on the wall, which destroys the decoration. An external unit needs to be hung outdoors, which is difficult to install and the structure is not compact enough. The other is an integrated structure of the internal and external units. Although it can install the evaporator and condenser of the air conditioner indoors, it is necessary to destroy a larger area of ​​the wall to install the heat exhaust pipe of the condenser, which not only increases the difficulty of installation, but also affects the beauty of the room. The integrated internal and external units usually include mobile air conditioners and window units. When the mobile air conditioner is used, it is necessary to manually connect the heat dissipation hose and put the hose outside the window, which is inconvenient to use; the window unit needs to open a square hole with a large area on the wall to put the machine in, and can be moved out when not in use, leaving a square hole on the wall. Although it can be blocked with other things, it is troublesome and destroys the decoration.

[0004] In addition, due to the limited space in the kitchen, the size of the kitchen air conditioner cannot be too large. Therefore, there is a big problem in the heat dissipation of the kitchen air conditioner. If the heat cannot be dissipated in time during the use of the kitchen air conditioner, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently of each other and the two cannot be linked. The heat generated by the kitchen air conditioner cannot be discharged to the outside through the fan of the range hood. Therefore, how to discharge the heat generated by the kitchen air conditioner through the range hood has become a problem that people need to solve urgently.

[0005] Although there are products such as air-conditioning hoods, which add air-conditioning components to the range hood platform, and can realize all the functions of the range hood and the functions of the air conditioner at the same time, these air-conditioning hoods often simply merge the functions of the traditional air-conditioning indoor unit and the traditional range hood, and the air-conditioning outdoor unit still needs to be installed separately outdoors. This type of air-conditioning range hood is not integrated enough, and the installation is cumbersome. In addition, the pipes and lines connecting the indoor and outdoor units of the air-conditioning will also damage the wall. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a kitchen air conditioning system with a compact structure and capable of discharging air from the front side of the range hood casing in view of the above-mentioned existing technical status.

The two ends of the four-way valve 15 are connected to the compressor 11, and the other two ends of the four-way valve 15 are respectively connected to the first heat exchanger 12 and the second heat exchanger 13. A throttling component 16 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. A refrigerant flows through the cold channel 4. Common refrigerants can be water, ethylene glycol or propylene glycol, etc. By switching the four-way valve 15, the system can switch between cooling mode and heating mode. In cooling mode, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator. In heating mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. The specific working principle of the air conditioning assembly 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0034] The oil fume suction component has a housing 20, and the compressor 11 is arranged in the housing or adjacent to the housing. The first fan 25 is installed in the housing 20. A smoke exhaust channel 21 is provided at the rear end of the fan air outlet, that is, the smoke exhaust channel 21 is provided downstream of the first fan 25 along the path of the oil fume flow. The smoke exhaust channel 21 of this embodiment includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212, and the oil fume suction component includes the first fan 25. The rear end of the air outlet of the first fan 25 is provided with a first air duct switching valve 3 for switching one of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 to be connected to the air outlet of the first fan 25. The first smoke exhaust port 213 of the first smoke exhaust channel 211 and the second smoke exhaust port 214 of the second smoke exhaust channel 212 are independent of each other, and can be connected to the corresponding smoke exhaust pipe (not shown in the figure) respectively. The first heat exchanger 12 of this embodiment is arranged in the first smoke exhaust channel 211, and an oil fume purification device 4 is also installed in the first smoke exhaust channel 211. The oil fume purification device 4 is arranged upstream of the first heat exchanger 12 along the path of the oil fume flow. The oil fume purification device 4 can generally adopt various electrostatic purification devices in the prior art to prevent the oil fume from polluting the first heat exchanger 12.

[0035] An air outlet passage 22 is also provided in the housing 20, and the air outlet passage 22 is isolated from the smoke exhaust passage 21. The second heat exchanger 13 and the second fan 26 are installed in the air outlet passage 22, and the second fan 26 and the second heat exchanger 13 are distributed on the left and right sides. Figure 1 The direction indicated by the middle arrow A is left. In this embodiment, the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are distributed vertically. The first smoke exhaust channel 211 is located on the left side of the second smoke exhaust channel 212, the air outlet channel 22 is located on the right side of the second smoke exhaust channel 212, and the second fan 26 is located above the first fan 25.

[0036] The air inlet 23 and the air outlet 24 of the air outlet channel 22 are both arranged on the housing 20. The air inlet 23 can be connected to the kitchen room or the outside of the kitchen, and the air outlet 24 is in a vertical strip shape and is arranged at the center or approximately the center of the front side of the housing 20, so that the air outlet 24 is directly connected to the kitchen room.

[0037] The working principle of the kitchen air conditioning system is as follows:

[0038] Taking the cooling mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator.

[0039] When both the range hood and the air conditioner are turned on, the first exhaust channel 211 is opened and the second exhaust channel 212 is closed by switching the first air duct switching valve 3. At this time, the oil smoke is discharged through the first exhaust channel 211, and the oil smoke airflow sweeping over the surface of the first heat exchanger 12 can cool and dissipate the heat of the first heat exchanger 12, thereby reducing the temperature of the coolant flowing through the first heat exchanger 12, thereby improving the heat exchange effect of the first heat exchanger 12, and further improving the energy efficiency of the air conditioner. At the same time, under the action of the second fan 26, the cold air is blown directly into the kitchen from the air outlet 24.

[0040] In the range hood only on mode, the second smoke exhaust channel 212 is opened by switching the first air duct switching valve 3, and the first smoke exhaust channel 211 is closed. At this time, the oil smoke sucked by the first fan 25 is discharged through the second smoke exhaust channel 212.

[0041] In the heating mode, the air duct switching method is the same as the cooling mode, except that the air outlet 24 delivers warm air to the kitchen, and the cold air of the first heat exchanger 12 is discharged along with the oil smoke.

[0042] When the system is cooling, the fume extraction component and the air conditioning component share a fan system, which can save material costs and space; when heating, in addition to sharing the fan, it can also fully absorb the waste heat generated by the stove to achieve energy-saving effects.
