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 demand 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. 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 holes need 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 that the internal and external units are integrated structures. Although the evaporator and condenser of the air conditioner can be installed indoors, a larger area of ​​the wall needs to be destroyed to install the heat exhaust pipe of the condenser, which not only increases the difficulty of installation, but also affects the beauty of the interior. Integrated indoor and outdoor units usually include mobile air conditioners and window units. When using a mobile air conditioner, you need to manually connect the heat dissipation hose and place the hose outside the window, which is inconvenient to use. For a window unit, you need to open a square, large hole in the wall to put the machine in. When not in use, you can move it out, leaving a square hole in the wall. Although it can be blocked with other things, it is troublesome and damages the decoration.

[0003] In addition, due to the limited space in the kitchen, the size of the kitchen air conditioner cannot be too large. Therefore, there are major problems in the heat dissipation of the kitchen air conditioner. If the kitchen air conditioner cannot dissipate heat in time during use, 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. Although, there are also products such as air conditioner hoods, that is, air conditioner components are added on the basis of the range hood platform, which can realize all the functions of the range hood and the function of the air conditioner at the same time. However, these air conditioner hoods often simply merge 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. This type of air conditioner hood is not integrated 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. In summary, further improvements need to be made to the existing kitchen air conditioning system. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system with a compact structure and capable of directly discharging air from a machine body in view of the above-mentioned existing technical status.

[0014] Further preferably, the first air duct switching valve and the second air duct switching valve are linked valve plates, and the first smoke exhaust channel and the second smoke exhaust channel can be selectively opened through the linkage of the first air duct switching valve and the second air duct switching valve.

[0015] As another preferred solution, the outlet of the first smoke exhaust channel constitutes an independent first air outlet, the outlet of the second smoke exhaust channel constitutes an independent second air outlet, and the first air outlet and the second air outlet merge into the second smoke exhaust pipe.

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figures 1 to 3 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 (not shown in the figure) is installed on the refrigerant pipeline 14. A throttling device 15 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. A refrigerant flows through the refrigerant pipeline 14. Common refrigerants can be water, ethylene glycol or propylene glycol, etc. By switching the four-way valve 15, the system can switch between the cooling mode and the heating mode. In the cooling mode, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator. In the 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 component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0032] The air conditioning component and the range hood component are integrated on the machine body 3. In this embodiment, the machine body 3 adopts a range hood, which includes a first fan 26. The first fan 26 is installed inside the machine body 3. A smoke exhaust channel 21 is formed inside the machine body 3 and downstream of the air outlet of the first fan 26. The first fan 26 is located below the smoke exhaust channel 21. An air outlet channel 22 is provided at the top of the machine body 3, that is, the air outlet channel 22 is located above the smoke exhaust channel 21, and the air outlet channel 22 is isolated from the smoke exhaust channel 21. In this embodiment, the smoke exhaust channel 21 has a transverse smoke exhaust section, and the air outlet channel 22 has a transverse air outlet section, and the transverse air outlet section is located above the transverse smoke exhaust section.

[0033] The smoke exhaust channel 21 of this embodiment specifically includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212. The first smoke exhaust channel 211 and the second smoke exhaust channel 212 are basically arranged horizontally along the body 3, and the first smoke exhaust channel 211 is located below the second smoke exhaust channel 212. A first air duct switching valve 41 is installed at the entrance of the first smoke exhaust channel 211 and the second smoke exhaust channel 212. By switching the first air duct switching valve 41, one of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be connected to the air outlet of the first fan 26. The outlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 share the first smoke exhaust pipe 61. A second air duct switching valve 42 is installed at the outlet of the first smoke exhaust channel 211 and the second smoke exhaust channel 212. By switching the second air duct switching valve 42, one of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be connected to the first smoke exhaust pipe 61. In this embodiment, the first air duct switching valve 41 and the second air duct switching valve 42 can be linked valve plates, through the linkage of the first air duct switching valve 41 and the second air duct switching valve 42, the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be selectively opened. The first air duct switching valve 41 and the second air duct switching valve 42 can also be independently opened valve plates.

[0034] The first heat exchanger 12 of this embodiment is arranged in the first smoke exhaust channel 211, and a fume purification device 5 is also installed in the first smoke exhaust channel 211. The fume purification device 5 is arranged upstream of the first heat exchanger 12 along the path of the fume flow. The fume purification device 5 can generally adopt various electrostatic purification devices in the prior art to prevent the fume from polluting the first heat exchanger 12. Figure 2 The middle arrow A indicates the right direction, and the oil fume purification device 5 is located on the left side of the first heat exchanger 12 .

[0035] In the embodiment, the compressor 11 is installed inside the machine body 3. In addition, the compressor 11 can also be installed at various locations in the kitchen.

[0036] The second heat exchanger 13 of this embodiment is arranged in the air outlet channel 22, and the air inlet 24 and the air outlet 23 of the air outlet channel 22 are both arranged on the machine body 3, the air inlet 24 is in fluid communication with the outside through the air inlet pipe 7, and the air outlet 23 is arranged on the front of the machine body 3 and directly communicates with the kitchen room. A second fan 27 is installed in the air outlet channel 22, and the second fan 27 is located upstream of the second heat exchanger 13 along the air flow path.

[0037] like Figure 4 As shown, the air outlet duct 22 has a return air outlet 25 in addition to the outdoor fresh air inlet. The return air outlet 25 is fluidly connected to the kitchen interior, so that the indoor return air mixes with the outdoor fresh air and enters the air outlet duct 22.

[0038] The system works as follows:

[0039] When both the range hood and air conditioner are turned on, Figure 1 As shown, the first air duct switching valve 41 swings to the left, the second air duct switching valve 42 swings upward, the first smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed, and the oil smoke passes through the oil smoke purification device 5 and the first heat exchanger 12 and is discharged from the first smoke exhaust channel 211, taking away the heat or cold of the first heat exchanger 12. At the same time, after the outdoor fresh air enters the air outlet channel 22, it is sent into the kitchen from the air outlet 23 of the air outlet channel 22 after heat exchange in the second heat exchanger 13. When the air conditioner is cooling, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator, and cold air is sent to the kitchen; when the air conditioner is heating, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser, and warm air is sent to the kitchen.

[0040] When only the range hood is on, Figure 2 As shown, the first air duct switching valve 41 swings right, the second air duct switching valve 42 swings downward, the first smoke exhaust channel 211 is closed and the second smoke exhaust channel 212 is opened, and the oil smoke is discharged through the second smoke exhaust channel 212.

[0041] Embodiment 2:

[0042] like Figures 3 to 5 As shown, the first smoke exhaust channel 211 of this embodiment constitutes an independent first air outlet 213, and the outlet of the second smoke exhaust channel 212 constitutes an independent second air outlet 214, and the first air outlet 213 and the second air outlet 214 merge into the second smoke exhaust pipe 62. The air inlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are switched by the air duct switching valve 4, and the air outlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 do not need to be installed with an air duct switching valve. The remaining structure and working principle of this embodiment can refer to the first embodiment, and will not be described in detail here.

[0043] In addition, the "fluid connection" referred to in the present invention refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), 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 that allows fluid to flow through, or a combination of the above.
