Description

Technical Field

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

[0002] Typical air conditioning systems consist of an indoor unit and an outdoor unit, connected by ductwork to allow refrigerant to circulate. However, with the increasing number of high-rise apartments in recent years, it is often difficult for residents on higher floors to install outdoor units. Therefore, the potential demand for integrated air conditioning systems that do not require an outdoor unit is increasing significantly.

[0003] In recent years, due to the intensification of abnormal climate worldwide, the number of cities experiencing extremely hot summers has been increasing. Living in rooms without air conditioning is not only uncomfortable but can also lead to heatstroke and other health problems, even posing a fatal risk in severe cases. Especially in kitchens, where open flames are used for cooking, the temperature rises more easily, thus creating a growing demand for integrated air conditioning systems that do not require outdoor units.

[0004] Furthermore, the space available for installing air conditioning equipment in the kitchen is very limited, and the suitable installation location varies from household to household. Existing kitchen air conditioning equipment cannot achieve a high degree of installation flexibility. 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. Furthermore, it features a first air outlet and a second air outlet located on different side walls. This multi-directional air outlet structure allows the air conditioner to select the optimal exhaust path based on the actual kitchen layout, and enables the corresponding first or second air outlet to connect with the exhaust vent on the wall according to installation requirements. This effectively avoids installation obstacles caused by space limitations and improves the user experience.

[0007] To achieve the above objectives, this utility model provides a kitchen air conditioner, comprising: The housing includes an indoor area and an outdoor area; the housing has an indoor air outlet for communicating with the indoor area. An indoor heat exchanger is disposed in the indoor area; Indoor fan; the indoor fan is installed in the indoor area, and the indoor fan is used to blow the airflow after heat exchange by the indoor heat exchanger into the room through the indoor air outlet. An outdoor heat exchanger is installed in the outdoor area; An outdoor fan, wherein the outdoor fan is installed in the outdoor area; The first air outlet is located on one side of the housing and communicates with the outdoor area; The second air outlet is located on one side of the housing and communicates with the outdoor area; The first air outlet and the second air outlet are located on different side walls of the housing.

[0008] This technical solution achieves a compact air conditioner by integrating the indoor and outdoor zones into a single housing. Traditional kitchen air conditioners are limited by their installation location due to the need to connect to an outdoor unit, making them particularly difficult to implement in high-rise apartments. This solution, however, only requires a single exhaust vent on the wall, significantly reducing installation difficulty and cost. Furthermore, the multi-directional airflow structure, with first and second air outlets located on different side walls, allows the air conditioner to select the optimal exhaust path based on the kitchen's layout. It also allows the corresponding first or second air outlet to connect to the wall-mounted exhaust vent, effectively avoiding installation obstacles caused by space constraints and enhancing the user experience.

[0009] In some embodiments of this application, the two sides of the housing in the width direction are the front side and the rear side, respectively, the indoor area is close to the front side of the housing, and the outdoor area is close to the rear side of the housing; The indoor air outlet is located on the front side of the housing; The first air outlet is located on the rear side of the housing.

[0010] This technical solution ensures that the front indoor air outlet can deliver air normally into the room, while the rear outlet delivers air outdoors, conforming to air conditioning installation habits and those of most kitchen air conditioners. This design is suitable for wall mounting, minimizing space occupation and meeting the modern kitchen's demand for "invisible installation" and "aesthetic integration" of appliances, offering both practicality and aesthetics.

[0011] In some embodiments of this application, there are multiple second air outlets, and each second air outlet is located on a different side wall of the housing.

[0012] In this technical solution, multiple secondary air outlets further expand the air conditioner's installation adaptability. Users can select the most suitable outlet based on the actual location of the exhaust vents in the kitchen, eliminating the need to adjust the installation location or make additional modifications due to incompatible exhaust paths. This design is particularly suitable for complex scenarios such as corner installations and ceiling installations, significantly improving the product's versatility and installation flexibility. Simultaneously, the multi-outlet structure facilitates flexible adjustments to the exhaust path during later maintenance or modifications, extending the product's lifespan and enhancing user satisfaction.

[0013] In some embodiments of this application, a cover plate is also included, the cover plate being disposed at the first air outlet and each of the second air outlets; The cover plate can open or close the corresponding first air outlet or second air outlet.

[0014] In this technical solution, during installation, only the air outlet corresponding to the exhaust vent is opened, while the other outlets remain closed. This ensures that all exhaust gas is discharged through a designated path, preventing airflow leakage and energy loss. This structure not only improves the system's exhaust efficiency but also effectively prevents dust, insects, and other foreign objects from entering the unit through unused outlets, ensuring the cleanliness and long-term stable operation of internal components. Furthermore, the cover design enhances the product's integrated appearance, meeting the modern home appliance design requirements of combining aesthetics and functionality.

[0015] In some embodiments of this application, an air guide is further included, one end of which is disposed at the first air outlet or the second air outlet, and the other end of which is used to connect to the exhaust port.

[0016] In this technical solution, the air guide component can be adjusted or replaced according to actual installation needs, adapting to various installation methods such as direct connection, elbow connection, or duct extension. This design is particularly suitable for scenarios where the exhaust vent and the air conditioning outlet are not perfectly aligned, achieving smooth deflection and connection through the air guide component, avoiding increased installation stress or duct resistance caused by forced alignment. Furthermore, the air guide component is also available as a standard accessory in various specifications to meet personalized installation needs, improving product adaptability and installation convenience.

[0017] In some embodiments of this application, the outdoor heat exchanger includes at least one bent portion. The outdoor fan is a centrifugal fan, and the windward side of the outdoor fan faces the bend.

[0018] In this technical solution, the bent heat exchanger increases the heat dissipation area and improves heat dissipation efficiency; while the centrifugal fan has high static pressure characteristics, enabling it to maintain a stable airflow in high-resistance environments and overcome the ventilation resistance caused by small-diameter exhaust, thick heat exchangers, and fine filters. This structure ensures that sufficient exhaust airflow and cooling performance can be maintained even in a compact body, making it suitable for scenarios with limited space and high heat dissipation requirements, such as kitchens.

[0019] In some embodiments of this application, the first air outlet or the second air outlet is used to correspond to and communicate with the exhaust outlet; The outlet side of the outdoor fan is designed to correspond to the exhaust vent.

[0020] In this technical solution, the outlet side of the outdoor fan is connected to the exhaust vent, ensuring that hot air is directly and efficiently discharged outdoors, reducing energy loss and noise caused by internal duct bends. This design optimizes the airflow path, improves the overall heat exchange efficiency and energy efficiency, and reduces the risk of high system pressure caused by obstructed airflow, enhancing the reliability and stability of the product during long-term operation.

[0021] In some embodiments of this application, a compressor is provided inside the housing, and the compressor is connected to the indoor heat exchanger and the outdoor heat exchanger through heat exchange pipelines; An expansion valve is installed on the heat exchange pipeline.

[0022] In this technical solution, the expansion valve can dynamically adjust its opening according to the system pressure, effectively reducing condenser pressure under high-pressure conditions and preventing system overload and component damage. This design is particularly suitable for high-pressure conditions in kitchen air conditioners due to space constraints, improving the system's adaptability and operational safety in harsh environments, while also balancing manufacturing costs and performance.

[0023] In some embodiments of this application, the indoor fan is a centrifugal fan; The outdoor heat exchanger and / or the indoor heat exchanger comprises at least three rows of heat transfer tubes.

[0024] This technical solution achieves higher heat exchange efficiency within a limited space. A centrifugal fan provides stable indoor airflow, while three rows of heat transfer tubes significantly increase the heat exchange area, improving cooling speed and energy efficiency ratio. This structure is particularly suitable for usage scenarios like kitchens, where temperature fluctuations are large and heat loads are high, ensuring that the air conditioner maintains strong cooling capacity even in high-temperature environments, meeting users' dual needs for rapid cooling and long-term stable operation.

[0025] In addition, this application also provides a kitchen air conditioner, which includes: The housing includes an indoor area and an outdoor area; the housing has an indoor air outlet for communicating with the indoor area. An indoor heat exchanger is disposed in the indoor area; Indoor fan; the indoor fan is installed in the indoor area, and the indoor fan is used to blow the airflow after heat exchange by the indoor heat exchanger into the room through the indoor air outlet. An outdoor heat exchanger is installed in the outdoor area; An outdoor fan, wherein the outdoor fan is installed in the outdoor area; The first air outlet is located on one side of the housing and communicates with the outdoor area; the first air outlet is located on one side of the housing in the width direction. The second air outlet is located on one side and / or the top wall of the housing along its length.

[0026] This technical solution achieves a compact air conditioner by integrating the indoor and outdoor zones into a single housing. Traditional kitchen air conditioners are limited by their installation location due to the need to connect to an outdoor unit, making them particularly difficult to implement in high-rise apartments. This solution, however, only requires a single exhaust vent on the wall, significantly reducing installation difficulty and cost. Furthermore, the multi-directional airflow structure, with first and second air outlets located on different side walls, allows the air conditioner to select the optimal exhaust path based on the kitchen's layout. It also allows the corresponding first or second air outlet to connect to the wall-mounted exhaust vent, effectively avoiding installation obstacles caused by space constraints and enhancing the user experience.

[0031] 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. In this application, the kitchen air conditioner includes a casing, within which are housed a compressor, an outdoor heat exchanger, an outdoor fan, a pressure relief component, an indoor heat exchanger, and an indoor fan. The compressor compresses refrigerant into high-temperature refrigerant and delivers it to the outdoor heat exchanger. The outdoor fan blows air across the outdoor heat exchanger to exchange heat, and the high-temperature air is then discharged outdoors, cooling the high-temperature refrigerant within the outdoor heat exchanger. The cooled refrigerant is then depressurized through the pressure relief component, becoming a low-temperature, low-pressure refrigerant. This low-temperature refrigerant enters the indoor heat exchanger, where it is further cooled by airflow from the indoor fan. The cooled air then enters the room to further cool the interior. Finally, the refrigerant that has passed through the indoor heat exchanger returns to the compressor, completing the cycle.

[0032] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings. Please refer to all the accompanying drawings. In one illustrative embodiment of the kitchen air conditioner of this utility model, the kitchen air conditioner includes a housing 100 for installation indoors. The kitchen air conditioner is an integrated air conditioner, therefore it has only one housing 100, which houses all structural components.

[0033] In some embodiments, the housing 100 includes an indoor zone 101 and an outdoor zone 102; the housing 100 has an indoor air outlet for communicating with the indoor zone 101. In the prior art, air conditioners include an outdoor unit and an indoor unit, which are connected by pipelines. In this application, however, the entire structure can be housed within a single housing 100, resulting in a compact structure, higher integration, and lower cost. Dividing the interior into indoor zone 101 and outdoor zone 102 allows for the separation of structures that would otherwise be located inside the outdoor and indoor units, preventing interference between them.

[0034] In some embodiments, the kitchen air conditioner further includes an indoor heat exchanger 200, which is disposed in the indoor zone 101; the indoor heat exchanger 200 is used to exchange heat with the indoor air.

[0035] In some embodiments, the kitchen air conditioner further includes an indoor fan 300; the indoor fan 300 is disposed in the indoor zone 101, and the indoor fan 300 is used to blow the airflow after heat exchange by the indoor heat exchanger 200 into the room through the indoor air outlet, thereby achieving the regulation of the indoor temperature.

[0036] In some embodiments, the kitchen air conditioner further includes an outdoor heat exchanger 400, which is disposed in the outdoor zone 102. The outdoor heat exchanger 400 is used for heat exchange between the refrigerant and the outdoor air, thereby reducing the temperature of the refrigerant and facilitating the subsequent cooling of the indoor air by the low-temperature refrigerant when it passes through the indoor heat exchanger 200.

[0037] In some embodiments, the kitchen air conditioner further includes an outdoor fan 500, which is located in the outdoor zone 102. The outdoor fan 500 is used to drive air to blow over the outdoor heat exchanger 400, thereby improving the heat exchange efficiency between the outdoor heat exchanger 400 and the air.

[0038] In some embodiments, the kitchen air conditioner further includes a first air outlet 700, which is located on one side of the housing 100 and communicates with the outdoor area 102. The high-temperature air after heat exchange in the outdoor heat exchanger 400 can be output through the first air outlet 700, thereby preventing the high-temperature air from entering the room and affecting indoor cooling.

[0039] In some embodiments, the kitchen air conditioner further includes a second air outlet 800, which is located on one side of the housing 100 and communicates with the outdoor area 102. The high-temperature air after heat exchange by the outdoor heat exchanger 400 can be output through the second air outlet 800, thereby preventing the high-temperature air from entering the room and affecting the indoor cooling.

[0040] In some embodiments, the first air outlet 700 and the second air outlet 800 are located on different side walls of the housing 100. During installation, the orientation of the housing 100 can be adjusted according to the site conditions to adapt to the installation requirements of different scenarios.

[0041] In existing technology, the housing 100 only has one air outlet. During installation, the existing exhaust vent on the wall may not align with the air outlet, making installation impossible. The only solution is to fill the existing exhaust vent and create a new one, or connect the air outlet and exhaust vent with a duct. This is inconvenient and may even prevent installation altogether.

[0042] Therefore, this application achieves a compact air conditioner by integrating the indoor zone 101 and the outdoor zone 102 into the same housing 100, as described above. Furthermore, traditional kitchen air conditioners are limited by their installation location due to the need to connect to an outdoor unit, making them particularly difficult to implement in high-rise apartments; while this solution only requires a single exhaust vent on the wall to complete the exhaust connection, greatly reducing installation difficulty and cost. In addition, a first air outlet 700 and a second air outlet 800 located on different side walls are provided. This multi-directional air outlet structure allows the air conditioner to select the optimal exhaust path according to the actual layout of the kitchen, and enables the corresponding first air outlet 700 or second air outlet 800 to connect to the exhaust vent on the wall according to installation requirements. This effectively avoids installation obstacles caused by space limitations and improves the user experience.

[0043] In some embodiments, the outdoor zone 102 and the indoor zone 101 within the housing 100 are separated by a partition. Firstly, this allows for quick differentiation between the outdoor zone 102 and the indoor zone 101, facilitating rapid installation during production and preventing installation errors. Secondly, it isolates airflow, preventing airflow from the outdoor heat exchanger 400 from entering the indoor zone 101 and subsequently the room, thus ensuring heat exchange efficiency.

[0044] In some embodiments, the partition is made of thermal insulation material. Because the indoor heat exchanger 200 and the outdoor heat exchanger 400 have different temperatures, the indoor zone 101 and the outdoor zone 102 also have different temperatures. Using thermal insulation material for the partition can better isolate the temperature and prevent the high temperature of the outdoor zone 102 from affecting the low temperature of the indoor zone 101, thus ensuring the cooling effect of the air conditioner on the indoor space.

[0045] In some embodiments, a compressor 600 is disposed within the housing 100, and the compressor 600 is connected to the indoor heat exchanger 200 and the outdoor heat exchanger 400 via heat exchange pipelines. The compressor 600, the indoor heat exchanger 200, and the outdoor heat exchanger 400 form a complete circuit through the heat exchange pipelines.

[0046] In some embodiments, the kitchen air conditioner further includes a pressure relief component, which is disposed in the heat exchange pipeline and located in a section between the indoor heat exchanger 200 and the outdoor heat exchanger 400. The compressor 600 compresses the refrigerant into high-temperature refrigerant and delivers it to the outdoor heat exchanger 400. The outdoor fan 500 blows airflow across the outdoor heat exchanger 400 to achieve heat exchange. The high-temperature air after heat exchange is output outdoors, at which point the high-temperature refrigerant in the outdoor heat exchanger 400 is cooled. The cooled refrigerant is depressurized through the pressure relief component, becoming a low-temperature, low-pressure refrigerant. This low-temperature refrigerant enters the indoor heat exchanger 200, where it is blown by the indoor fan 300 for heat exchange. The cooled air then enters the room to cool the indoor environment. The refrigerant that has passed through the indoor heat exchanger 200 returns to the compressor 600 to complete the cycle.

[0047] In some embodiments, the pressure relief component can be a pressure relief valve, which can adjust its opening degree. Therefore, adjusting the opening degree of the pressure relief valve can regulate the flow of refrigerant, thereby regulating the temperature of the kitchen air conditioner.

[0048] In some embodiments, the pressure relief element can be a capillary tube. Capillary tubes have a simple structure and lower cost, and utilize their inherent throttling and pressure reduction characteristics to stably convert the high-pressure liquid refrigerant in the outdoor heat exchanger 400 into low-pressure mist refrigerant.

[0049] In some embodiments, an expansion valve is installed on the heat exchange pipeline. The expansion valve can dynamically adjust its opening according to the system pressure, effectively reducing the condenser pressure under high-pressure conditions and preventing system overload and component damage. This design is particularly suitable for high-pressure conditions in kitchen air conditioners due to space constraints, improving the system's adaptability and operational safety in harsh environments, while also balancing manufacturing costs and performance.

[0050] It is understandable that the aforementioned expansion valve and pressure relief valve can be a single unit.

[0051] In some embodiments, the two sides of the housing 100 in the width direction are the front and rear sides, respectively. The indoor area 101 is close to the front side of the housing 100, and the outdoor area 102 is close to the rear side of the housing 100. The indoor air outlet is located on the front side of the housing 100, and the first air outlet 700 is located on the rear side of the housing 100. This design ensures that the indoor air outlet on the front side can normally supply air into the room, and the air outlet on the rear side can supply air to the outside, which conforms to the installation habits of air conditioners and most kitchen air conditioners. This form is suitable for wall installation, minimizing space occupation, meeting the modern kitchen's demand for "invisible installation" and "aesthetic integration" of home appliances, and has good practicality and aesthetics.

[0052] In some embodiments, the housing 100 has a rectangular structure. The front and rear sides of the housing 100 are the two vertical sides along the width direction, respectively. The second air outlet 800 is located at the top of the housing 100. When the air conditioner needs to be installed under a cabinet or in a corner where lateral space is limited, the top air outlet can be easily connected directly to the pre-installed exhaust duct or upward-extending exhaust path in the ceiling, effectively avoiding installation failures caused by the inability to connect lateral pipes. This design achieves upward guidance of the exhaust path, which is particularly suitable for the ceiling decoration style commonly found in modern kitchens, allowing the air conditioner to be perfectly integrated into the overall cabinet system, maintaining the visual neatness and unity of the kitchen. At the same time, the top air outlet structure helps to utilize the principle of natural rising of hot air, which to a certain extent promotes exhaust efficiency, reduces the energy consumption of the outdoor fan 500, and achieves a unity of functionality and aesthetics.

[0053] In some embodiments, the second air outlet 800 is located at one end of the length of the housing 100. This significantly enhances the adaptability of the kitchen air conditioner in narrow or non-standard spaces. When the kitchen layout causes the air conditioner to be flush against the wall or cabinet, making it impossible to connect pipes to the rear (first air outlet 700) and top, the second air outlet 800 located at the end of the length of the housing 100 provides a lateral exhaust channel. This allows the air conditioner to be flexibly embedded in special locations such as corners and cabinet ends, achieving wall-mounted installation without affecting the exhaust function. This design effectively solves the layout limitations caused by a single installation location. Users can choose the most convenient connection scheme according to the specific location of the exhaust outlet, greatly reducing installation difficulty and modification costs, and improving the product's versatility in complex home environments and user satisfaction.

[0054] In some embodiments, there are multiple second air outlets 800, each located on a different side wall of the housing 100. Multiple second air outlets 800 further expand the air conditioner's installation adaptability. Users can select the most suitable outlet for connection based on the actual location of the exhaust vents in the kitchen, eliminating the need to adjust the installation location or make additional modifications due to incompatible exhaust paths. This design is particularly suitable for complex scenarios such as corner installations and ceiling installations, significantly improving the product's versatility and installation freedom. Simultaneously, the multi-outlet structure facilitates flexible adjustment of the exhaust path during later maintenance or modifications, extending product lifespan and enhancing user satisfaction.

[0055] In some embodiments, there may be two second air outlets 800, which are respectively located at the top of the housing 100 or at any end of the length of the housing 100. Users can flexibly choose to connect to either the top or side outlet, depending on the limitations of existing ventilation conditions such as ceiling pipes and side wall openings in the kitchen, effectively avoiding installation problems or additional modifications caused by conflicting installation locations. This design allows the air conditioner to seamlessly adapt to various complex installation scenarios such as corners, above and below cabinets, and narrow passageways.

[0056] In some embodiments, there may be two second air outlets 800, which are respectively disposed at both ends of the housing 100 along its length. When one end of the air conditioner cannot be connected to the exhaust system due to being close to a wall, cabinet or duct, the air outlet at the other end can be directly connected to the exhaust system.

[0057] In some embodiments, there may be three second air outlets 800, which are respectively disposed at the top of the housing 100 and at both ends in the length direction. This maximizes the variety of installation possibilities for the housing 100.

[0058] Understandably, due to the structure and installation limitations of the housing 100, there will be no air outlet at the bottom of the housing 100. Firstly, the bottom of the housing 100 typically faces the room and the user, and it will not be used to conform to the wall. Secondly, kitchen air conditioners are most likely to be installed above the range hood, therefore the bottom of the housing 100 is used to conform to the range hood, making it impossible to install an air outlet.

[0059] In some embodiments, a cover plate is also included, disposed at the first air outlet 700 and each of the second air outlets 800; the cover plate can open or close the corresponding first air outlet 700 or second air outlet 800. During installation, only the air outlet corresponding to the exhaust hole is opened, while the other air outlets remain closed, ensuring that all exhaust is concentrated and discharged through a designated path, avoiding airflow leakage and energy loss. This structure not only improves the exhaust efficiency of the system but also effectively prevents dust, insects, and other foreign objects from entering the machine through unused air outlets, ensuring the cleanliness and long-term stable operation of internal components. In addition, the cover plate design enhances the integrated appearance of the product, meeting the design requirements of modern home appliances that combine aesthetics and functionality.

[0060] In some embodiments, the number of covers is the sum of the number of first air outlets 700 and second air outlets 800. The covers are pre-fabricated onto the housing 100 at the factory. During installation, the user or worker can remove the corresponding cover as needed.

[0061] In some embodiments, an air guide component is also included, with one end of the air guide component disposed at the first air outlet 700 or the second air outlet 800, and the other end of the air guide component used to connect to the exhaust outlet. The air guide component can be adjusted or replaced according to actual installation requirements, adapting to various installation methods such as direct connection, elbow connection, or duct extension. This design is particularly suitable for scenarios where the exhaust vent and the air conditioning outlet are not perfectly aligned, achieving smooth deflection and connection through the air guide component, avoiding increased installation stress or duct resistance caused by forced alignment. In addition, the air guide component can also be provided as a standard accessory in various specifications to meet personalized installation needs, improving product adaptability and installation convenience.

[0062] In some embodiments, the air guide can be a bend, with one end connected to and communicating with a first air outlet 700 or a second air outlet 800, and the other end connected to and communicating with an exhaust vent on the wall. The bend enables a non-linear connection between the air conditioner's air outlet and the wall exhaust vent, greatly improving the installation's tolerance and adaptability. When the air conditioner's air outlet and the wall's pre-reserved exhaust vent are misaligned laterally or longitudinally due to installation location limitations, the bend can bridge the two misaligned interfaces through its bending angle, forming a smooth and sealed exhaust channel.

[0063] In some embodiments, the air guide can be a flexible hose. Due to its ability to bend and extend freely, the flexible hose can easily overcome and compensate for complex spatial deviations between the air outlet and the exhaust outlet, achieving smooth and sealed connection regardless of lateral misalignment, longitudinal drop, or angular tilt.

[0064] In some embodiments, the outdoor heat exchanger 400 includes at least one bend, and the outdoor fan 500 uses a centrifugal fan with its windward side facing the bend. The bend-type heat exchanger increases the heat dissipation area and improves heat dissipation efficiency; while the centrifugal fan has high static pressure characteristics, enabling it to maintain a stable airflow in high-resistance environments and overcome the ventilation resistance caused by small-diameter exhaust, thick heat exchangers, and fine filters. This structure ensures sufficient exhaust airflow and cooling performance even in a compact design, making it suitable for space-constrained environments such as kitchens where high heat dissipation requirements are necessary.

[0065] In some embodiments, the first air outlet 700 or the second air outlet 800 is used to correspond to and connect with the exhaust outlet; the air outlet side of the outdoor fan 500 is used to correspond to the exhaust outlet. The air outlet side of the outdoor fan 500 is connected to the exhaust outlet to ensure that hot air is directly and efficiently discharged outdoors, reducing energy loss and noise caused by internal duct bends. This design optimizes the airflow path, improves the overall heat exchange efficiency and energy efficiency level of the unit, while reducing the risk of high system pressure caused by obstructed airflow, and enhancing the reliability and stability of the product during long-term operation.

[0066] In some embodiments, the position of the outdoor fan 500 can be adjusted. For example, when the first air outlet 700 corresponds to the exhaust outlet, the position of the outdoor fan 500 can be adjusted so that the air outlet of the outdoor fan 500 faces the first air outlet 700.

[0067] In some embodiments, the indoor fan 300 is a centrifugal fan; the outdoor heat exchanger 400 and / or the indoor heat exchanger 200 include at least three rows of heat transfer tubes. Higher heat exchange efficiency is achieved within a limited space. The centrifugal fan provides stable indoor airflow, while the three rows of heat transfer tubes significantly increase the heat exchange area, improving cooling speed and energy efficiency ratio. This structure is particularly suitable for usage scenarios such as kitchens with large temperature fluctuations and high heat loads, ensuring that the air conditioner maintains strong cooling capacity even in high-temperature environments, meeting users' dual needs for rapid cooling and long-term stable operation.

[0068] In addition, this application also provides a kitchen air conditioner, which includes, but is not limited to, the aforementioned housing 100, indoor heat exchanger 200, indoor fan 300, outdoor heat exchanger 400, and outdoor fan 500. The main difference lies in: The first air outlet 700 is located on one side of the housing 100 and communicates with the outdoor area 102; the first air outlet 700 is located on one side of the housing 100 in the width direction. The second air outlet 800 is located on one side and / or the top wall of the housing 100 along its length.

[0069] By integrating the indoor zone 101 and the outdoor zone 102 into the same housing 100, the air conditioner achieves a compact design. Furthermore, traditional kitchen air conditioners are limited by installation location due to the need to connect to an outdoor unit, making them particularly difficult to implement in high-rise apartments; while this solution only requires a single exhaust vent on the wall to complete the exhaust connection, greatly reducing installation difficulty and cost. In addition, the design includes a first air outlet 700 and a second air outlet 800 located on different side walls. This multi-directional airflow structure allows the air conditioner to select the optimal exhaust path based on the actual kitchen layout, and the corresponding first air outlet 700 or second air outlet 800 can be connected to the exhaust vent on the wall according to installation requirements. This effectively avoids installation obstacles caused by space limitations and improves the user experience.

[0070] 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.
