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

[0009] In order to realize air duct switching, a first fan is arranged in the casing, and a first air duct switching valve for switching one of the first smoke exhaust channel and the second smoke exhaust channel to be connected to the first fan outlet is installed at the rear end of the first fan outlet.

[0010] Preferably, the first smoke exhaust channel is arranged below the second smoke exhaust channel.

[0011] The technical solution adopted by the present invention to solve the second technical problem is: in the kitchen air conditioning system, the first heat exchanger is arranged in the first smoke exhaust channel. In this way, when the system is cooling, the oil fume suction component and the air conditioning component share a fan system, which can save material cost and space; when heating, in addition to sharing the fan, the waste heat generated by the stove can be fully absorbed to achieve energy saving effect.

[0012] In order to prevent the oil smoke from contaminating the first heat exchanger, an oil smoke purification device is installed in the first smoke exhaust channel, and the oil smoke purification device is arranged upstream of the first heat exchanger along the path of the oil smoke flow.

[0013] The smoke exhaust channel and the air outlet channel may have multiple positional relationships, the air outlet channel at least has a transverse air outlet section, the smoke exhaust channel at least has a transverse smoke exhaust section, and the transverse air outlet section is located above the transverse smoke exhaust section.

[0014] In order to enable the smoke exhaust channel to be switched at the smoke duct outlet, the first smoke exhaust channel and the second smoke exhaust channel are both connected to the smoke exhaust pipe, and a second air duct switching valve is installed at the outlet of the first smoke exhaust channel and the outlet of the second smoke exhaust channel to switch one of the first smoke exhaust channel and the second smoke exhaust channel to be connected to the smoke exhaust pipe.

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1 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. 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.

[0033] The oil fume suction assembly has a housing 20, and the compressor 11 can be arranged adjacent to or inside the housing 20. The housing 20 is provided with a smoke exhaust passage 21 and an air outlet passage 22 that are isolated from each other. Figure 1 The arrow A in the middle indicates the right direction, and the smoke exhaust channel 21 and the air outlet channel 22 are both arranged horizontally from left to right, and the air outlet channel 22 is located above the smoke exhaust channel 21. A first fan 26 for exhausting oil smoke is installed at the lower part of the housing, and the first fan 26 is located below the smoke exhaust channel 21 and the air outlet channel 22, and the air outlet of the first fan 26 is fluidly connected to the smoke exhaust channel 21.

[0034] The smoke exhaust passage 21 specifically includes a first smoke exhaust passage 211 and a second smoke exhaust passage 212 . The first smoke exhaust passage 211 and the second smoke exhaust passage 212 are substantially arranged transversely along the housing 20 , and the first smoke exhaust passage 211 is located below the second smoke exhaust passage 212 .

[0035] The first air duct switching valve 3 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 3, 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 second air duct switching valve is installed at the outlet of the first smoke exhaust channel 211 and the second smoke exhaust channel 212. The second air duct switching valve of this embodiment is a one-way valve 61. The first smoke exhaust channel 211 and the second smoke exhaust channel 212 share the same smoke exhaust pipe 5 for smoke exhaust. By switching the one-way valve 61, one of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be connected to the smoke exhaust pipe 5.

[0036] 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.

[0037] The housing 20 is provided with an air inlet 23 and an air outlet 24 of the air outlet channel 22, and the second heat exchanger 13 and the second fan 27 are installed in the air outlet channel 22. The air inlet 23 can be in fluid communication with the inside of the kitchen, and can also be in fluid communication with the outside of the kitchen. The air outlet 24 is arranged at the top of the housing 20 and is externally connected to an upper air outlet pipe 25, and the air outlet of the upper air outlet pipe 25 is in fluid communication with the inside of the kitchen. Usually, the air outlet of the upper air outlet pipe 25 can be arranged on the kitchen ceiling, so that cold air or warm air can be sent to the kitchen through the air outlet on the ceiling. In this embodiment, the upper air outlet pipe 25 is located on the left side of the smoke exhaust pipe 5.

[0038] The working principle of the kitchen air conditioning system is as follows:

[0039] Taking the cooling mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator.

[0040] The range hood and the air conditioner are both turned on. By switching the first air duct switching valve 3 and the one-way valve 61, the first air duct switching valve 3 is swung to the left, the one-way valve 61 is vertical, the first smoke exhaust channel 211 is opened, and the second smoke exhaust channel 212 is closed. At this time, the oil smoke enters the smoke exhaust pipe 5 through the first smoke exhaust channel 211 and is discharged outward, 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 coolant 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 second fan 27, the cold air is directly sent into the kitchen from the air outlet 24.

[0041] Only the range hood is turned on, and the first air duct switching valve 3 and the one-way valve 61 are switched so that the first air duct switching valve is vertical and the one-way valve 61 is horizontal, that is, the second smoke exhaust channel 212 is opened and the first smoke exhaust channel 211 is closed. At this time, the oil smoke sucked by the first fan 26 enters the smoke exhaust pipe 5 through the second smoke exhaust channel 212 and is exhausted to the outside, and because the second air duct switching valve adopts the one-way valve 61, the oil smoke exhausted from the second smoke exhaust channel 212 can be prevented from entering the first smoke exhaust channel 211, so as to avoid contaminating the oil smoke purification device 4 and the first heat exchanger 12.

[0042] In the heating mode, the air duct switching method is the same as the cooling mode, the difference is that the air outlet 24 blows warm air into the kitchen, and the cold air of the first heat exchanger 12 is discharged with the oil smoke.

[0043] 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.

[0044] Embodiment 2:

[0045] like Figure 2 As shown, the smoke outlet duct 22 of this embodiment is located on the right side of the smoke exhaust channel 21, the upper air outlet pipe 25 is located on the right side of the smoke exhaust pipe 5, and the remaining structures are the same as those in the first embodiment and will not be described in detail here.

[0046] Embodiment three:

[0047] like Figure 3 and Figure 4 As shown, in this embodiment, the second fan 27 is installed in the upper air outlet duct 25, and the second fan is a cross-flow fan, and the positions of the upper air outlet duct 25 and the smoke exhaust pipe 5 can be interchanged left and right. Figure 5 As shown, the air outlet of the upper air outlet pipe 25 is a U-shaped air outlet 251. The remaining structure and working principle of this embodiment can refer to the first embodiment, and will not be described in detail here.

[0048] Embodiment 4:

[0049] like Figure 6 As shown, the second air duct switching valve of this embodiment includes a first valve plate 62 and a second valve plate 63. The first valve plate 62 is installed at the outlet of the first smoke exhaust channel 211, and the second valve plate 63 is installed at the outlet of the second smoke exhaust channel 212. When the air conditioning system is turned on, the first air duct switching valve 3 swings left, the first valve plate 62 rotates to vertical, the second valve plate 63 rotates to horizontal, 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 4 and the first heat exchanger 12 and is discharged from the first smoke exhaust channel 211 to the smoke exhaust pipe 5, and finally discharged to the outside, while taking away the heat or cold of the first heat exchanger 12. When the air conditioning system is not turned on, the first air duct switching valve 3 is in a vertical position, the first valve plate 62 rotates to horizontal, the second valve plate 63 rotates to vertical, the first smoke exhaust channel 211 is closed and the second smoke exhaust channel 212 is opened, and the oil smoke is discharged to the outside through the second smoke exhaust channel 212 and the smoke exhaust pipe 5.

[0050] Embodiment five:

[0051] like Figure 7 As shown, the second air duct switching valve of this embodiment includes a third valve plate 64 and a fourth valve plate 65. The third valve plate 64 is installed at the outlet of the first smoke exhaust channel 211, and the fourth valve plate 65 is installed at the outlet of the second smoke exhaust channel 212. A spring 66 is installed on both the third valve plate 64 and the fourth valve plate 65. The working principle is as follows:

[0052] When the air conditioning system is turned on, the first air duct switching valve 3 swings to the left, the third valve plate 64 is vertical, the fourth valve plate 65 is vertical, the first exhaust channel 211 is opened and the second exhaust channel 212 is closed. The first exhaust channel 211 is used for heat dissipation and exhaust of oil smoke by the air conditioning system. When the compressor is turned on, the oil smoke flows into the exhaust pipe 5 through the oil smoke purification device 4 and the first heat exchanger 12. At this time, the second fan 27 is turned on, and the cold air or warm air flows into the kitchen through the air outlet panel of the upper air outlet pipe through the air outlet 24. When the air conditioning system is turned on, the first air duct switching valve 3 is vertical, the third valve plate 64 swings to the left, the fourth valve plate 65 is horizontal, the second exhaust channel 212 is opened and the first exhaust channel 211 is closed, and the oil smoke is discharged through the second exhaust channel 212 and the exhaust pipe 5.

[0053] 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.
