Kitchen air conditioning system

Abstract

A kitchen air conditioning system includes an air conditioning component comprising a compressor, a first heat exchanger, and a second heat exchanger. A fume extraction component has an exhaust duct and an air outlet duct. The air outlet of the exhaust duct is in fluid communication with the interior of the kitchen. The first heat exchanger is located within the exhaust duct, and the second heat exchanger is located within the air outlet duct. This kitchen air conditioning system integrates the first heat exchanger of the air conditioning component into the exhaust duct, and the second heat exchanger into the air outlet duct. The system has a compact structure, organically combining the air conditioning component and the fume extraction component, resulting in a high degree of integration. The fumes discharged from the exhaust duct can also remove heat or cold from the first heat exchanger, improving its heat exchange efficiency and thus enhancing the air conditioning energy efficiency. During cooling, a single fan system is used, saving material costs and space. During heating, in addition to sharing a fan, it can also fully absorb waste heat generated by the stove, achieving energy-saving effects.

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

[0083] The present invention is further described in detail below with reference to the accompanying drawings.

[0084] Embodiment 1:

[0085] like Figures 1 to 4As 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.

[0086] The oil fume extraction assembly has a housing 20, and the compressor is arranged adjacent to the oil fume extraction assembly, for example, it can be integrated on the oil fume extraction assembly, can be installed inside the housing 20 or located outside the housing and installed on the housing 20, and a fan rack (not shown) is also arranged inside the housing 20, and an installation cavity is formed between the housing and the fan rack, and the compressor can be installed in the installation cavity. In addition, the compressor can also be installed at various locations in the kitchen, for example, the compressor can be installed on the ceiling.

[0087] A smoke exhaust passage 21 and an air outlet passage 22 are isolated from each other inside the housing 20. In this embodiment, the smoke exhaust passage 21 has a transverse smoke exhaust section, and the air outlet passage 22 has a transverse air outlet section, and the transverse air outlet section is located above the transverse smoke exhaust section. A first fan 26 for exhausting oil smoke is installed at the lower part of the housing 20, and the first fan 26 is located below the smoke exhaust passage 21 and the air outlet passage 22, and the air outlet of the first fan 26 is fluidly connected to the smoke exhaust passage 21.

[0088] The smoke exhaust channel 21 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 shell 20, and the first smoke exhaust channel 211 is located below the second smoke exhaust channel 212. A 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 outlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 share the same smoke exhaust pipe 5. A second air duct switching valve is installed at the outlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212. In this embodiment, the second air duct switching valve is a one-way check valve 61, which can prevent oil smoke from flowing back into the first smoke exhaust channel 211.

[0089] The first heat exchanger 12 of this embodiment is arranged in the first smoke exhaust channel 211, and a fume purification device 4 is also installed in the first smoke exhaust channel 211. The fume purification device 4 is arranged upstream of the first heat exchanger 12 along the path of the fume flow. The fume purification device 4 can generally adopt various electrostatic purification devices in the prior art to prevent the fume from polluting the first heat exchanger 12. Figure 1 The middle arrow A indicates the right direction, and the oil fume purification device 4 is located on the left side of the first heat exchanger 12 .

[0090] The casing 20 is provided with an air inlet 23 and an air outlet 24 of the air outlet channel 22, and a second heat exchanger 13 is installed in the air outlet channel 22. The air inlet 23 can be in fluid communication with the interior of the kitchen, and can also be in fluid communication with the exterior of the kitchen. The air outlet 24 is provided at the top of the casing 20 and is externally connected to an air outlet duct 25. The left and right positions of the air outlet duct 25 and the smoke exhaust duct 5 are not limited. The air outlet of the air outlet duct 25 is in fluid communication with the interior of the kitchen. Usually, the air outlet of the air outlet duct 25 can be provided on the kitchen ceiling, so that cold air or warm air can be supplied to the kitchen through the air outlet on the ceiling. The second fan 27 can be installed in the air outlet channel 22, and the second heat exchanger 13 is provided downstream of the second fan 27 along the direction of air flow. Figure 1 As shown, the second fan 27 installed in the air outlet channel 22 is a centrifugal fan; the second fan 27 can also be installed in the air outlet pipe 25, such as Figures 2 to 4 As shown, the second fan 27 installed in the air outlet pipe 25 is a cross-flow fan.

[0091] The system works as follows:

[0092] When both the range hood and the air conditioning system are turned on, the first air duct switching valve 3 swings left, the one-way check valve 61 opens, the first smoke exhaust channel 211 opens and the second smoke exhaust channel 212 closes, 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, while taking away the heat or cold of the first heat exchanger 12. When only the range hood is turned on, the first air duct switching valve 3 swings right, the one-way check valve 61 closes, the first smoke exhaust channel 211 closes and the second smoke exhaust channel 212 opens, and the oil smoke is discharged through the second smoke exhaust channel 212.

[0093] like Figure 5 As shown, the second air duct switching valve 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.

[0094] like Figure 6 As shown, the second air duct switching valve 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. Springs 66 are installed on both the third valve plate 64 and the fourth valve plate 65.

[0095] Here’s how it works:

[0096] 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 smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed. The first smoke exhaust channel 211 is used for heat dissipation and oil smoke exhaust of the air conditioning system. When the compressor is turned on, the oil smoke flows into the smoke 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 air outlet pipe through the air outlet 24. When the air conditioning system is not 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 smoke exhaust channel 212 is opened and the first smoke exhaust channel 211 is closed, and the oil smoke is discharged through the second smoke exhaust channel 212 and the smoke exhaust pipe 5.

In the air outlet channel 22, the positions of the second fan 27 and the second heat exchanger 13 can be interchanged left and right.

[0099] The distribution of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 of this embodiment is not limited. Figure 7 As shown, the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are arranged horizontally, and the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are arranged up and down with respect to each other, and which channel is on the top and which channel is on the bottom is not specifically limited. Figures 8 to 11 As shown, the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are arranged vertically, and the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are distributed up and down with respect to each other, and there is no specific limitation on which channel is on the top and which channel is on the bottom.

[0100] In this embodiment, the first fan 26 and the second fan 27 are both centrifugal fans. The first fan 26 can be vertically distributed or horizontally distributed, and the second fan 27 is usually vertically distributed. Fig. 9 As shown, the first fan 26 and the second fan 27 of this embodiment are both arranged horizontally and share a fan motor 28, and a clutch 29 is installed on the motor shaft of the fan motor 28, and the first fan 26 and the second fan 27 are coupled to each other through the clutch 29. When the range hood and the air conditioning system are both turned on, the first fan 26 and the second fan 27 rotate synchronously, and when only the range hood is turned on, the first fan 26 and the second fan 27 are disengaged, and only the first fan 26 needs to be turned on.

[0101] The first air duct switching valve 3 can be opened in a variety of ways, such as Fig.11 As shown, the opening is performed by an external driver 31 .

[0102] The working principle of this embodiment is the same as that of the first embodiment, and will not be described in detail here.
