Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and more particularly to a kitchen air conditioner. Background Technology

[0002] A kitchen air conditioner is an air conditioning device specifically designed for the kitchen environment. Kitchens generate a large amount of heat, fumes, and steam during cooking, making it difficult for ordinary air conditioners to adapt to this unique environment. Kitchen air conditioners typically feature high-temperature resistance, oil stain resistance, and high airflow, effectively lowering the kitchen temperature, improving the cooking environment, and allowing chefs and cooks to work comfortably in hot weather. They also help maintain suitable temperatures for food and equipment in the kitchen, extending their lifespan. Therefore, they are one of the important home appliances for improving comfort and work efficiency in modern kitchens.

[0003] Currently available professional kitchen air conditioners have several drawbacks, including numerous installation requirements, extensive drilling, and significant damage to existing kitchen renovations. Installation necessitates large-scale demolition or adjustment of the ceiling and corresponding joists, as well as drilling into the walls, making the process complex and costly. Furthermore, some models are wider and larger than standard range hoods, requiring the removal of the existing range hood for replacement. This results in lower cooling capacity and a very high price, necessitating the purchase of the range hood along with the air conditioner.

[0004] In summary, existing kitchen air conditioners suffer from multiple drawbacks, including high price, difficult installation, and large size. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a kitchen air conditioner that can be integrated into the decorative cover on top of the kitchen range hood, without occupying additional space. This design avoids large-scale demolition or alteration of existing kitchen decorations, reduces wall drilling, and lowers the complexity and cost of the installation process. The cooling pipes deliver air from the roof, which can be installed on the ceiling of the kitchen, and based on the principle of cold air sinking, the cool air can be delivered directly above the user's head, improving user comfort.

[0007] To achieve the above objectives, this utility model provides a kitchen air conditioner, which is installed on the upper part of a kitchen range hood, wherein the areas located on the upper part of the kitchen range hood and on both sides of the exhaust pipe are respectively the first area and the second area.

[0008] The kitchen air conditioner includes:

[0009] A first heat exchanger is located in the first region;

[0010] A first fan is located in the first area and is used to drive air toward the first heat exchanger.

[0011] A second heat exchanger is located in the second region; the second heat exchanger and the first heat exchanger are connected by a refrigerant pipeline;

[0012] The second fan is located in the second area and is used to drive air toward the second heat exchanger.

[0013] A compressor for supplying refrigerant to the first heat exchanger and the second heat exchanger;

[0014] A heat exhaust pipe that connects the second region to the flue pipe;

[0015] A cooling duct, one end of which is connected to the first area, and the other end of which extends to the roof and supplies air from top to bottom.

[0016] In this technical solution, the compressor delivers refrigerant to the second heat exchanger. A second fan blows indoor air towards the second heat exchanger to cool the refrigerant. The hot air, after heat exchange with the second heat exchanger, is directly transported outdoors through the exhaust pipe. The cooled refrigerant is then delivered to the first zone, where a first fan blows hot indoor air towards the first heat exchanger. The air is cooled by the first heat exchanger and then transported to the roof through a cooling pipe for top-down cooling. This design allows the kitchen air conditioner to be integrated into the decorative cover above the kitchen range hood, without occupying extra space. Furthermore, this design avoids large-scale demolition or alteration of existing kitchen renovations, reduces wall drilling, and lowers the complexity and cost of installation. The cooling pipes, supplying air from the roof, can be installed on the kitchen ceiling, and based on the principle of cold air sinking, the cool air is delivered directly above the user's head, improving user comfort.

[0017] In some embodiments of this application, a third region communicating with the interior is located below the second region;

[0018] The compressor is located within the third area;

[0019] The third region is connected to the second region via a connecting channel;

[0020] A third fan is also provided in the third area, which is used to transport airflow to the second area through the connecting channel; the second heat exchanger is located in the third area.

[0021] In this technical solution, air enters the third zone under the action of the third fan to exchange heat with the second heat exchanger, thereby cooling the refrigerant. Air then enters the second zone through a connecting channel, where it further exchanges heat with the second heat exchanger to cool the refrigerant. The hot air is then discharged through the exhaust pipe under secondary pressurization by the second fan. This ensures that the air is pressurized and discharged, preventing the fumes drawn in by the range hood from flowing back into the second zone.

[0022] In some embodiments of this application, it further includes:

[0023] A first housing, the interior of which is a first region;

[0024] The second housing, the interior of which is the second region;

[0025] The third housing, the interior of which is the third region.

[0026] The technical solution provides independent protective spaces for each component of the kitchen air conditioner. Users do not need to plan and set up the first, second, and third zones themselves. During installation, the first, second, and third housings are simply installed. This modular design makes installation and maintenance of each part more convenient, and also facilitates flexible installation and fixing on top of the kitchen range hood, enhancing the product's versatility and adaptability.

[0027] In some embodiments of this application, the first housing is provided with a return air vent for communicating with the indoor area and the first region;

[0028] The third housing has an air inlet for connecting the interior with the first area.

[0029] In this technical solution, a return air vent is provided on the first casing to allow indoor air to flow smoothly into the first zone, providing sufficient air for heat exchange with the first heat exchanger. An air inlet on the third casing further ensures the inflow of indoor air, improving the cooling efficiency of the air conditioner. This design ensures effective air circulation, enhancing the cooling capacity and comfort of the kitchen air conditioner.

[0030] In some embodiments of this application, a cover plate is provided on the outside of the third housing, the cover plate being used to close or open the air inlet.

[0031] In the technical solution, when the kitchen air conditioner is not in use, the air inlet is sealed with a cover plate to prevent oil fumes from entering the third and second zones, thus avoiding damage to the compressor, second fan, third fan, and second heat exchanger caused by oil stains, and improving the service life of the kitchen air conditioner.

[0032] In some embodiments of this application, a T-junction is also included, which is used to connect the exhaust pipe, the common flue, and the heat exhaust pipe.

[0033] In the technical solution, the design of the three-way pipe allows the exhaust pipe and the air conditioning heat exhaust pipe to share a common flue, reducing the occupation of kitchen space, lowering the installation difficulty and cost, and also avoiding excessive alteration to the kitchen building walls, which complies with the relevant regulations of the property management.

[0034] In some embodiments of this application, the tee pipe includes a main pipe and a branch pipe; the two ends of the main pipe are respectively connected to a common flue and an exhaust pipe; the branch pipe connects the heat exhaust pipe to the main pipe;

[0035] The branch pipe is inclined from the side facing the exhaust pipe toward the direction away from the main pipe;

[0036] The minimum angle between the branch pipe and the main pipe is 30°.

[0037] In the technical solution, the design of the main and branch pipes of the tee pipe, as well as the inclination angle of the branch pipe and the minimum angle between it and the main pipe, ensures effective connection and smooth heat dissipation between the air conditioner heat exhaust pipe and the exhaust pipe. This structure can ensure the air volume performance of both when the air conditioner and the range hood are working simultaneously, avoid mutual interference, improve the efficiency of the entire kitchen ventilation system, and also ensure the normal operation and heat dissipation efficiency of the kitchen air conditioner.

[0038] In some embodiments of this application, a first check valve is provided at the end of the main pipe near the exhaust pipe; and a second check valve is provided on the branch pipe.

[0039] In this technical solution, the first check valve effectively prevents the backflow of cooking fumes into the air conditioner when the range hood is operating alone. The second check valve effectively prevents hot air from flowing into the room via the hydraulic press when the kitchen air conditioner is used alone. The installation of these two check valves ensures the normal operation of the air conditioner under different working conditions, prevents cooking fumes from polluting and damaging the air conditioner components, extends the lifespan of the air conditioner, and also improves the air quality in the kitchen.

[0040] In some embodiments of this application, a first check valve is provided on the flue pipe; and a second check valve is provided on the heat exhaust pipe.

[0041] In this technical solution, the first check valve effectively prevents the backflow of cooking fumes into the air conditioner when the range hood is operating alone.

[0068] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0069] In this application, the kitchen air conditioner includes a first heat exchanger and an indoor fan. It comprises a first heat exchanger, an indoor fan, a second heat exchanger, an outdoor fan, and a compressor. The compressor circulates refrigerant within the first and second heat exchangers. Under the action of the indoor fan, indoor air enters the casing and exchanges heat with the first heat exchanger before being output to the room. The refrigerant that has undergone heat exchange in the first heat exchanger flows into the outdoor unit, where the outdoor fan exchanges the heat from the refrigerant with the second heat exchanger, thus achieving circulation.

[0070] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0071] Please refer to all the accompanying drawings. In one illustrative embodiment of the kitchen air conditioner of this utility model, the kitchen air conditioner is used to be installed on the upper part of the kitchen range hood 100. The areas located on the upper part of the kitchen range hood 100 and on both sides of the exhaust pipe are respectively the first area and the second area.

[0072] Furthermore, the side of the kitchen range hood 100 that is attached to the wall is the rear side, and the side facing the user is the front side. The remaining two sides in the width direction of the kitchen range hood 100 are the left and right sides, respectively. The first area and the second area of ​​this application are located on the left and right sides of the kitchen range hood 100, respectively.

[0073] In some embodiments, the kitchen air conditioner includes a first heat exchanger 200 and a first fan 300. The first heat exchanger 200 is located in a first area; the first fan 300 is located in the first area and is used to drive air towards the first heat exchanger 200. The first heat exchanger 200, as a key component for heat exchange between the refrigerant and the air, absorbs heat from the air through the evaporation process of the refrigerant, thereby lowering the air temperature. The first fan 300 is responsible for continuously blowing hot air from the kitchen towards the first heat exchanger 200, ensuring sufficient contact and efficient heat exchange between the air and the heat exchanger.

[0074] In some embodiments, the kitchen air conditioner includes a second heat exchanger 400 and a second fan 500, the second heat exchanger 400 being located in a second area; the second heat exchanger 400 and the first heat exchanger 200 are connected by a refrigerant pipeline. The second fan 500 is located in the second area and is used to drive air toward the second heat exchanger 400.

[0075] In some embodiments, the kitchen air conditioner includes a compressor 600 for supplying coolness to a first heat exchanger 200 and a second heat exchanger 400.

[0076] In some embodiments, the kitchen air conditioner includes a heat exhaust pipe 800 that connects the second area to the exhaust pipe. The heat generated during condensation in the second heat exchanger 400 provides an efficient exhaust path. Through the heat exhaust pipe 800, hot air can be directly guided to the exhaust pipe and then discharged outdoors, ensuring continuous and stable operation of the kitchen air conditioner during cooling and preventing decreased cooling efficiency or overheating damage due to heat accumulation. Furthermore, the heat exhaust pipe 800 allows the kitchen air conditioner to fully utilize the existing kitchen exhaust system, reducing additional space occupation and lowering installation difficulty and cost.

[0077] In some embodiments, the kitchen air conditioner includes a cooling duct 900, one end of which is connected to a first area and the other end which extends to the roof and supplies air from top to bottom.

[0078] Through the above scheme, compressor 600 delivers refrigerant to the second heat exchanger 400, and the second fan 500 blows indoor air towards the second heat exchanger 400 to cool the refrigerant inside. The hot air after heat exchange with the second heat exchanger 400 is directly delivered to the outside through the heat exhaust pipe 800. The refrigerant cooled by the second heat exchanger 400 is then delivered to the first zone, where the first fan 300 blows the hot indoor air towards the first heat exchanger 200. The air is cooled by the first heat exchanger 200 and then delivered to the roof through the cold air pipe 900 for cooling from top to bottom. This design allows the kitchen air conditioner to be integrated into the decorative cover on top of the kitchen range hood 100, without occupying extra space. Furthermore, this design avoids large-scale demolition or adjustment of existing kitchen decorations, reduces wall drilling, and lowers the complexity and cost of the installation process. The cooling pipes deliver air from the roof and can be installed on the ceiling of a home kitchen. Based on the principle that cold air sinks, the cold air can be delivered directly to the user's head, improving the user's comfort.

[0079] In some embodiments, a third zone communicating with the interior is located below the second zone; the compressor 600 is disposed within the third zone; the third zone and the second zone are connected via a connecting channel; a third fan 700 is also disposed within the third zone, which is used to deliver airflow to the second zone through the connecting channel; a second heat exchanger 400 is partially located within the third zone. Under the action of the third fan 700, air enters the third zone and exchanges heat with the second heat exchanger 400 to cool the refrigerant. Air enters the second zone through the connecting channel and exchanges heat with the second heat exchanger 400 to further cool the refrigerant. The hot air is then discharged through the exhaust pipe 800 under secondary pressurization by the second fan 500. This ensures that the air is pressurized and discharged, preventing the fumes sucked up by the range hood 100 from flowing back into the second zone.

[0080] In this application, the third zone is located below the second zone to facilitate the upward flow of hot air, thereby facilitating the entry and exhaust of hot air into the common flue.

[0081] In another embodiment, the third region may be positioned above the second region.

[0082] In some embodiments, the kitchen air conditioner further includes a first housing 101, the interior of which is a first region. The first housing 101 is disposed on one side of the exhaust pipe of the kitchen range hood 100 in the width direction. The first housing 101 is directly installed inside the decorative cover on top of the range hood 100. This provides an independent installation space for the first heat exchanger 200 and the first fan 300, ensuring their stable operation on top of the range hood 100. This layout of the first housing 101 allows the kitchen air conditioner to make full use of the unused space on top of the range hood 100, avoiding space occupation in other areas of the kitchen and optimizing the utilization efficiency of kitchen space.

[0083] In some embodiments, the kitchen air conditioner further includes a second housing 102, the interior of which is a second region; the second housing 102 is located on the side of the kitchen range hood 100 away from the first housing 101 in the width direction of the exhaust pipe. The first housing 101 is directly installed inside the decorative cover on the top of the range hood 100. This allows the kitchen air conditioner to make full use of the unused space on both sides of the top of the range hood 100, achieving efficient space utilization. The second housing 102 also provides independent installation space for the second heat exchanger 400 and the second fan 500.

[0084] In some embodiments, the kitchen air conditioner further includes a third housing 103, the interior of which is a third area. The third housing 103 is installed inside a decorative cover on top of the range hood 100, and the second housing 102 is disposed above the third housing 103. The kitchen air conditioner can make better use of the space above the range hood 100, avoiding encroachment on other areas of the kitchen, thereby improving space utilization.

[0085] The aforementioned first housing 101, second housing 102, and third housing 103 provide independent protective spaces for each component of the kitchen air conditioner. Users do not need to plan and set up the first, second, and third zones themselves. During installation, the first housing 101, second housing 102, and third housing 103 can be directly installed. This modular design makes the installation and maintenance of each part more convenient, and also facilitates flexible installation and fixing on the upper part of the kitchen range hood 100, enhancing the product's versatility and adaptability.

[0086] In some embodiments, the second housing 102 and the third housing 103 can be integrally formed, i.e., a box, with a partition provided inside the box to divide the internal space of the box into an upper and lower second region and a third region.

[0087] In some embodiments, the first heat exchanger 200 is vertically arranged, which effectively increases the contact area with air and improves heat exchange efficiency. When the kitchen air conditioner is running, the first fan 300 blows hot indoor air toward the vertically arranged first heat exchanger 200, allowing the air to come into more full contact with the heat exchanger surface, so that heat is absorbed by the heat exchanger more quickly, thereby achieving more efficient cooling.

[0088] In some embodiments, the second heat exchanger 400 is vertically arranged, which effectively increases the contact area with air and improves heat exchange efficiency. When the kitchen air conditioner is running, the second fan 500 blows hot indoor air toward the vertically arranged second heat exchanger 400, allowing the air to make more full contact with the heat exchanger surface, so that heat is absorbed by the heat exchanger more quickly, thereby achieving more efficient cooling.

[0089] In some embodiments, the first housing 101 has a return air vent for communicating with the first area; the third housing 103 has an air inlet for communicating with the first area. The return air vent on the first housing 101 allows indoor air to smoothly enter the first area, providing sufficient air for heat exchange with the first heat exchanger 200. The air inlet on the third housing 103 further ensures the inflow of indoor air, improving the cooling efficiency of the air conditioner. This design ensures effective air circulation, enhancing the cooling capacity and comfort of the kitchen air conditioner.

[0090] In some embodiments, the return air vent is located on the side of the first housing 101 closest to the front of the kitchen range hood 100. This can also be understood as the return air vent being located on the side of the first housing 101 facing the user. Since the heat generated during kitchen cooking is mainly concentrated on the countertop and surrounding area, where the user is typically located, placing the return air vent on the user-facing side allows for more direct intake of warm air from the user's surroundings, achieving faster cooling. This layout not only improves the cooling efficiency of the air conditioner but also allows for more precise temperature regulation of the user's area, enhancing user comfort.

[0091] In some embodiments, a baffle is provided on the outside of the first housing 101, and the baffle is used to close or open the return air vent. When the kitchen air conditioner is not in use, closing the return air vent with the baffle can prevent oil fumes from entering the first area, prevent oil stains from covering and damaging the first fan 300 and the first heat exchanger 200, and improve the service life of the kitchen air conditioner.

[0092] Specifically, the baffle can be hinged to the first housing 101; it can also slide on the first housing 101; or it can be detachably connected to the first housing 101.

[0093] In some embodiments, a cover plate is provided on the outside of the third housing 103, which is used to close or open the air inlet. When the kitchen air conditioner is not in use, closing the air inlet with the cover plate can prevent oil fumes from entering the third and second areas, and prevent oil stains from covering and damaging the compressor 600, the second fan 500, the third fan 700, and the second heat exchanger 400, thereby improving the service life of the kitchen air conditioner.

[0094] Specifically, the cover plate can be hinged to the second housing 102; it can also slide on the second housing 102; or it can be detachably connected to the second housing 102.

[0095] In some embodiments, a tee pipe 110 is also included, which is used to connect the exhaust pipe, the common flue, and the heat dissipation pipe 800. The design of the tee pipe 110 allows the exhaust pipe and the air conditioning heat dissipation pipe 800 to share the common flue, reducing the space occupied in the kitchen, lowering the installation difficulty and cost, and also avoiding excessive alterations to the kitchen building walls, thus complying with the relevant regulations of the property management.

[0096] In some embodiments, the tee pipe 110 includes a main pipe 111 and a branch pipe 112; the two ends of the main pipe 111 are respectively connected to a common flue and an exhaust pipe; the branch pipe 112 connects the heat exhaust pipe 800 to the main pipe 111; the branch pipe 112 is inclined from the side facing the exhaust pipe toward the direction away from the main pipe 111.

[0097] In some embodiments, the minimum included angle between the branch pipe 112 and the main pipe 111 is less than 90°. This design helps optimize the airflow path and improve heat dissipation efficiency. When the included angle between the branch pipe 112 and the main pipe 111 is less than 90°, the airflow within the branch pipe 112 and the main pipe 111 is smoother, reducing eddies and resistance caused by excessive angles.

[0098] In some embodiments, the minimum included angle between branch pipe 112 and main pipe 111 is 30°. The design of the main pipe 111 and branch pipe 112 of the tee pipe 110, as well as the inclination angle of branch pipe 112 and the minimum included angle between it and the main pipe 111, ensures effective connection and smooth heat dissipation between the air conditioning heat exhaust pipe 800 and the exhaust pipe. This structure, when the air conditioner and the range hood 100 are working simultaneously, can maximize the exhaust performance of both, avoid mutual interference, improve the efficiency of the entire kitchen ventilation system, and also ensure the normal operation and heat dissipation efficiency of the kitchen air conditioner.

[0099] In some embodiments, a first check valve is provided at the end of the main pipe 111 near the exhaust pipe;

[0100] In some embodiments, a first check valve is provided on the exhaust pipe. This first check valve effectively prevents the backflow of cooking fumes into the air conditioner when the range hood 100 is operating alone. The first check valve ensures the normal operation of the air conditioner under different operating conditions, avoids contamination and damage to the air conditioner components from cooking fumes, extends the service life of the air conditioner, and also improves the air quality in the kitchen.

[0101] In some embodiments, a second check valve is provided on the branch pipe 112.

[0102] In some embodiments, a second check valve is provided on the heat exhaust pipe 800. This second check valve effectively prevents hot air from flowing into the room through the hydraulic press when the kitchen air conditioner is used alone. The second check valve ensures the normal operation of the air conditioner under different working conditions, prevents oil fumes from polluting and damaging the air conditioner components, extends the service life of the air conditioner, and also improves the air quality in the kitchen.

[0103] Furthermore, this application also provides a kitchen air conditioner, which differs from the above-mentioned solution in that the compressor 600 is located in the second zone. In this solution, the compressor 600, the second heat exchanger 400, and the second fan 500 are all located in the second zone, without a separate third zone, which can further reduce the space occupied. This solution can be used when the space above the kitchen range hood 100 is limited.

[0104] In some embodiments, a third fan 700 may also be provided in the second area. Both the third fan 700 and the second fan 500 blow airflow toward the second heat exchanger 400 and pressurize it before delivering it to the heat exhaust pipe 800, thereby achieving the discharge of hot air.

[0105] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
