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 also products such as air-conditioning hoods, which add air-conditioning components on the basis of the range hood platform, which can realize all the functions of the range hood and the functions of the air conditioner at the same time. However, these air-conditioning hoods often simply merge the functions of the indoor unit of the traditional air conditioner with the traditional range hood, and the outdoor unit of the air conditioner still needs to be installed separately outdoors. The integration of this type of air-conditioning range hood is not enough, and the installation is relatively cumbersome. Moreover, the pipe and line connection between the indoor and outdoor units of the air conditioner will also damage the wall. Moreover, the air conditioning component and the range hood component of the existing air-conditioning hood are not organically combined. For example, its exhaust channel is not much different from the exhaust channel of the existing range hood, and the exhaust channel has not been improved due to the combination of the range hood component and the air conditioning component. Summary of the invention

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component and a fume extraction component. The air conditioning component includes a compressor 11, a first heat exchanger 12 and a second heat exchanger 13. The compressor 11, the first heat exchanger 12 and the second heat exchanger 13 are connected through a refrigerant pipeline 14. A four-way valve 15 is installed on the refrigerant pipeline 14. 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. The specific working principle of the air conditioning component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0027] by Figure 1 The direction indicated by the middle arrow A is right. The oil fume suction component has a housing 20. The housing 20 is provided with a mutually isolated exhaust channel 21, an air outlet channel 22 and a compressor installation chamber 28. The air outlet channel 22 is located on the right side of the exhaust channel 21, and the compressor installation chamber 28 is located on the right side of the air outlet channel 22. The first heat exchanger 12 is installed in the exhaust channel 21, the second heat exchanger 13 is installed in the air outlet channel 22, and the compressor 11 is installed in the compressor installation chamber 28. An oil fume suction fan 25 is installed at the lower part of the housing 20. The oil fume suction fan 25 of this embodiment adopts a horizontally arranged centrifugal fan. The so-called horizontal arrangement means that the motor shaft of the fan is arranged vertically. In addition, along the flow direction of the oil fume, the exhaust channel 21 is arranged downstream of the oil fume suction fan 25.

[0028] The smoke exhaust channel 21 of this embodiment includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212. Both the first smoke exhaust channel 211 and the second smoke exhaust channel 212 have at least a transverse smoke exhaust section. The transverse smoke exhaust section of the first smoke exhaust channel 211 is located below the transverse smoke exhaust section of the second smoke exhaust channel 212. The oil fume suction fan 25 is located below the first smoke exhaust channel 211. The first heat exchanger 12 is installed in the first smoke exhaust channel 211. In order to prevent the oil fume from polluting the first heat exchanger 12, an oil fume purification device 6 is also installed in the first smoke exhaust channel 211, and the oil fume purification device 6 is arranged upstream of the first heat exchanger 12 along the oil fume flow direction. The oil fume purification device 6 can generally adopt various electrostatic purification devices in the prior art.

[0029] In this embodiment, the entrances of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are arranged adjacent to each other and a first valve plate 3 is arranged at the entrance, so that the two entrances can be opened selectively. The exits of the first smoke exhaust channel 211 and the second smoke exhaust channel 21 are arranged adjacent to each other and a second valve plate 4 is arranged at the exit. The exit of the second smoke exhaust channel 212 is always in an open state. The second valve plate 4 is used to open or close the exit of the first smoke exhaust channel 211, and the first valve plate 3 and the second valve plate 4 can be linked under the drive of the linkage mechanism 5 so that one of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 is in an open state, while the other is in a closed state. In this embodiment, the exit of the first smoke exhaust channel 211 and the exit of the second smoke exhaust channel 212 are both connected to the smoke exhaust pipe 7.

[0030] The linkage mechanism 5 of this embodiment is installed in the second smoke exhaust passage 212, and the linkage mechanism 5 specifically includes a motor 51, a lower connecting rod 52, an upper connecting rod 53, a slider 54, a guide groove 55, a first valve stem 56, and a second valve stem 57. Among them, the lower end of the lower connecting rod 52 is installed on the output shaft of the motor 51, the upper end of the lower connecting rod 52 is rotatably connected to the lower end of the upper connecting rod 53, the slider 54 is installed on the upper end of the upper connecting rod 53, the guide groove 55 is horizontally arranged, the slider 54 is arranged in the guide groove 55, the first valve stem 56 is horizontally arranged, the first valve plate 3 is vertically arranged, the first end of the first valve stem 56 is connected and fixed to the top of the first valve plate 3, the second end of the first valve stem 56 is fixed to the first end of the guide groove 55, the first end of the second valve stem 57 is fixed to the second end of the guide groove 55, the second valve plate 4 is horizontally arranged and installed at the second end of the second valve stem 57, and the outlet of the first smoke exhaust passage 211 is vertically upward and located below the second valve plate 4.

[0031] like Figure 2 As shown, when the lower connecting rod 52 and the upper connecting rod 53 are both in the vertical position, the first valve plate 3 moves upward to open the entrance of the first smoke exhaust channel 211 and close the entrance of the second smoke exhaust channel 212, and the second valve plate 4 moves upward to open the outlet of the first smoke exhaust channel 211. At this time, the first smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed.

[0032] like Figure 4 As shown, the motor 51 drives the lower connecting rod 52 to swing right, and then drives the upper connecting rod 53 to swing and move closer to the lower connecting rod 52. Then, the first valve stem 26 drives the first valve plate 3 to move downward to close the entrance of the first smoke exhaust channel 21 and open the entrance of the second smoke exhaust channel 212. The second valve plate 27 drives the second valve plate 4 to move downward to close the outlet of the first smoke exhaust channel 211. At this time, the first smoke exhaust channel 211 is closed and the second smoke exhaust channel 212 is opened.

[0033] In addition, a first limit block 58 is installed at the first end of the first valve stem 56, and a second limit block 59 is installed at the lower edge of the entrance of the second smoke exhaust channel 212. When the first valve plate 3 is lowered to close the entrance of the first smoke exhaust channel 211, the first limit block 58 is lowered to a position where it collides with the second limit block 59 and completely opens the entrance of the second smoke exhaust channel 212.

[0034] The housing 20 is provided with an air inlet 23 and an air outlet 24 of the air outlet channel 22. An air outlet fan 26 is installed in the air outlet channel 22. The air inlet 23 is fluidly connected to the outside of the kitchen or to the outside of the kitchen. The air outlet 24 of the air outlet channel 22 is arranged at the top of the housing 20 and is externally connected to an upper air outlet pipe 27. The air outlet of the upper air outlet pipe 27 is fluidly connected to the inside of the kitchen, and finally air is supplied to the inside of the kitchen from the air outlet of the upper air outlet pipe 27. In addition, the air outlet 24 of the air outlet channel 22 can also be directly connected to the inside of the kitchen, for example, the air outlet 24 can be arranged on the front of the housing 20.

[0035] The working process of the kitchen air conditioning system is as follows:

[0036] like Figure 1 and Figure 2 As shown, when the range hood and the air conditioner are both turned on, the first smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed.

[0037] When the air conditioner is cooling, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator. The oil smoke is discharged into the exhaust pipe 7 through the first exhaust channel 211, and the oil smoke airflow passes over the surface of the first heat exchanger 12 to cool and dissipate the heat of the first heat exchanger 12, thereby reducing the temperature of the refrigerant flowing through the first heat exchanger 12, thereby improving the heat exchange effect of the first heat exchanger 12, and then improving the energy efficiency of the air conditioner. At the same time, under the action of the air outlet fan 26, the cold air comes out of the air outlet 24 and enters the upper air outlet duct 27, and is then transported to the kitchen.

[0038] When the air conditioner is heating, the first heat exchanger 12 is an evaporator, and the second heat exchanger 13 is a condenser. The upper air outlet duct 27 sends warm air to the kitchen, and the cold energy of the first heat exchanger 12 is discharged into the exhaust pipe 7 along with the oil smoke.

[0039] like Figure 3 and Figure 4 As shown, when only the range hood is turned on, the first smoke exhaust channel 211 is closed, and the smoke sucked in by the range hood fan 25 is discharged into the smoke exhaust pipe 7 through the second smoke exhaust channel 212.

[0040] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
