Description

Technical Field

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

[0002] The kitchen is the primary place where people cook, and the quality of the kitchen air environment directly impacts the cooking experience. Kitchens are hot in the summer and cold in the winter, creating a need for both cooling and heating. To address this, various kitchen air conditioners have been invented to cool the kitchen air in the summer and provide warm air in the winter, enhancing cooking comfort. Existing kitchen air conditioners are essentially the same as standard air conditioners and generally come in two types. One type has a split indoor and outdoor unit, with the outdoor unit located outdoors and the indoor unit indoors, each unit having a motor and fan. This type requires piping to connect the indoor and outdoor units, requiring a hole in the wall and disrupting the interior design. The outdoor unit also needs to be mounted outdoors, making installation difficult and the structure less compact. Another type has an integrated indoor and outdoor unit. While this allows both the evaporator and condenser to be installed indoors, it requires destroying a larger area of ​​wall to install the condenser's heat exhaust pipe, increasing installation complexity and affecting the aesthetics 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; a window unit requires a square, large hole to be opened on the wall to place the unit in. It 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 both troublesome and damages the decoration.

[0003] Furthermore, due to limited kitchen space, kitchen air conditioners cannot be too large. Consequently, heat dissipation from kitchen air conditioners presents significant challenges. If heat cannot be dissipated promptly during use, the air conditioner's energy efficiency will be significantly reduced. However, existing kitchen air conditioners and range hoods operate independently, preventing them from being linked. Heat generated by the kitchen air conditioner cannot be discharged outdoors through the range hood's fan. Therefore, how to dissipate this heat through the range hood has become a pressing issue. While some existing air conditioner hoods incorporate air conditioning components into the range hood platform, achieving both the functions of a range hood and an air conditioner, these hoods often simply combine the functions of a traditional air conditioner's indoor unit with those of a traditional range hood, while the outdoor unit still needs to be installed separately outdoors. This approach to range hoods lacks integration and is cumbersome to install. Furthermore, the piping and wiring connecting the indoor and outdoor units can damage the wall. In summary, further improvements are needed to existing kitchen air conditioning systems. Summary of the Invention

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component and a range hood 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 via a refrigerant pipeline 14. A four-way valve (not shown) is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. 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 glycerol. 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 serves as a condenser and the second heat exchanger 13 serves as an evaporator. In heating mode, the first heat exchanger 12 serves as an evaporator and the second heat exchanger 13 serves as a condenser. The specific operating principle of the air conditioning component 1 is the same as that of existing air conditioners and will not be described in detail here.

[0028] This kitchen air conditioning system includes a housing 3, with air conditioning components and a range hood assembly integrally integrated within the housing 3. The range hood assembly utilizes a range hood, which includes a first fan 25 installed within the housing 3. A smoke exhaust passage 21 is formed within the housing 3, downstream of the air outlet of the first fan 25. The first fan 25 is located below the smoke exhaust passage 21. An air outlet passage 22 is provided at the top of the housing 3, positioned above and isolated from the smoke exhaust passage 21. In this embodiment, the smoke exhaust passage 21 includes a transverse smoke exhaust section, and the air outlet passage 22 includes a transverse air outlet section, both of which are located above the transverse smoke exhaust section.

[0029] 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 arranged substantially horizontally along the housing 3, with the first smoke exhaust channel 211 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 25. 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, and the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be selectively opened through the linkage of the first air duct switching valve 41 and the second air duct switching valve 42. The first air duct switching valve 41 and the second air duct switching valve 42 can also be independently opened valve plates.

[0030] The first heat exchanger 12 of this embodiment is arranged in the first exhaust channel 211, and an oil fume purification device 5 is also installed in the first exhaust channel 211. The oil fume purification device 5 is arranged upstream of the first heat exchanger 12 along the path of oil fume flow. The oil fume purification device 5 can generally adopt various electrostatic purification devices in the prior art to prevent oil fume from contaminating 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 .

[0031] In the embodiment, the compressor 11 is installed inside the casing 3 . In addition, the compressor 11 can also be installed at various locations in the kitchen. For example, the compressor can be installed on the kitchen ceiling 9 .

[0032] In this embodiment, the air inlet 23 and air outlet 24 of the air outlet duct 22 are both located on the housing 3. The air inlet 23 can be fluidly connected to the kitchen interior or to the outside of the kitchen via the air inlet duct 8. A second fan 26 is installed within the air outlet duct 22 and is located downstream of the second heat exchanger 13 along the air flow path. An air supply vent 91 is formed in the kitchen ceiling 9, and the air outlet 24 of the air outlet duct 22 is connected to the air supply vent 91 via the air outlet duct 7.

[0033] The system works as follows:

[0034] When both the range hood and the air conditioner are turned on, Figure 1As shown, the first air duct switching valve 41 swings left, and the second air duct switching valve 42 swings upward, opening the first smoke exhaust duct 211 and closing the second smoke exhaust duct 212. The cooking fumes pass through the cooking fume purification device 5 and the first heat exchanger 12 and are then discharged from the first smoke exhaust duct 211, carrying away the heat or cooling energy of the first heat exchanger 12. Simultaneously, fresh outdoor air enters the air outlet 22, undergoes heat exchange in the second heat exchanger 13, and is then delivered into the kitchen from the air supply vent 91 on the kitchen ceiling 9. During cooling mode, the first heat exchanger 12 acts as a condenser and the second heat exchanger 13 acts as an evaporator, delivering cold air to the kitchen. During heating mode, the first heat exchanger 12 acts as an evaporator and the second heat exchanger 13 acts as a condenser, delivering warm air to the kitchen.

[0035] 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.

[0036] Example 2:

[0037] 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. The first air outlet 213 and the second air outlet 214 converge 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 equipped with an air duct switching valve. Within the air outlet channel 22, along the air flow path, the second fan 26 is located upstream of the second heat exchanger 13. The remaining structure and operating principle of this embodiment can be referred to in Example 1 and will not be described in detail here.

[0038] In addition, the "fluid communication" 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, conduit, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
