Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a kitchen air conditioning device. Background Technology

[0002] The kitchen is the hottest and most smoky area in the home, especially during cooking, where high temperatures and fumes can severely impact user comfort. Therefore, installing dedicated air conditioning units in the kitchen has become an urgent need to improve the quality of modern home life. Unlike air conditioners used in ordinary rooms, kitchen air conditioners, in addition to needing strong cooling capacity, usually need to be embedded in cabinets or integrated into the system. Therefore, their dimensions, especially thickness and volume, have very stringent requirements.

[0003] To achieve a compact structure, existing kitchen air conditioners or similar small air conditioning units typically have an internal layout simply divided into two main functional areas: an evaporator side for absorbing indoor heat and blowing out cool air, and a condenser side for dissipating heat to the outside. This two-chamber layout separates the cold and hot sides with a partition to prevent crosstalk between hot and cold air and ensure basic cooling functionality.

[0004] However, in this common two-chamber design, the compressor is usually placed in the condenser side chamber, sharing the same space with heat dissipation components such as the condenser and condenser fan. To insulate and reduce noise from the compressor, additional insulation materials such as sound insulation cotton, heat insulation boards, or partitions are often required. These additional insulation materials occupy the already limited internal space within the casing, directly increasing the complexity of the structure and the overall physical size of the machine, making it difficult to reduce the size or make it thinner.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] In view of the problems pointed out in the background art, this application provides a kitchen air conditioning device that, through an integrated structural design, achieves excellent heat insulation and noise reduction for the compressor while meeting the stringent miniaturization design requirements of kitchen air conditioners without increasing or even reducing the number of parts.

[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This application provides a kitchen air conditioning device, including: a housing; a refrigeration system disposed within the housing, including a compressor, a condenser, a throttling device, and an evaporator connected in sequence by refrigeration pipes; a condensing fan for driving airflow through the condenser; and an evaporating fan for driving airflow through the evaporator to form a cooling airflow. The interior of the housing is divided into a compressor cavity for accommodating the compressor, an evaporating side cavity for accommodating the evaporator and the evaporating fan, and a condensing side cavity for accommodating the condenser and the condensing fan. The compressor cavity is disposed between the evaporating side cavity and the condensing side cavity. The housing is provided with: a first partition, one end of which is connected to the end of the evaporator and the other end of which is connected to the housing, to separate the compressor cavity and the evaporating side cavity; a second partition, one end of which is connected to the end of the evaporator and the other end of which is connected to the end of the condenser; and an outwardly extending partition portion on the outer shell of the condensing fan, the partition portion, the second partition, and a portion of the condensing fan outer shell together forming a separation structure for separating the compressor cavity and the condensing side cavity.

[0008] In some embodiments of this application, the first partition and a portion of the housing together define the evaporator-side return air duct; the partition structure and a portion of the housing together define the condenser-side return air duct. By combining the functions of the chamber partition and the duct wall into one, an additional dedicated duct plate is eliminated, achieving a higher degree of structural integration, further compressing the internal space, and making the layout more compact.

[0009] In some embodiments of this application, a water collection tray is further included on the lower side of the evaporator. One end of the water collection tray is connected to the second partition plate, and together with the partition structure, it separates the compressor cavity from the condenser side cavity. The water collection tray, while collecting water, also serves as a partition structure at the bottom of the equipment, enhancing the cavity's sealing performance and eliminating the need for a potential bottom partition plate, thus optimizing space utilization.

[0010] In some embodiments of this application, an electrical control box is also included, which is fixedly disposed within the condenser-side cavity and located above the condenser. By placing the electrical control box in the unused space above the condenser, the vertical utilization rate of the internal space is improved, and the existing heat dissipation airflow is used for heat dissipation, avoiding the need for a separate cooling fan or a larger heat dissipation space, which is beneficial for miniaturization.

[0011] In some embodiments of this application, a fixing bracket is also included. The outer surface of the housing has a groove, and the fixing bracket is embedded and fixed within the groove so that it does not protrude from the outer surface contour of the housing. The fixing bracket employs a concealed installation structure, ensuring that the installation components are not exposed after the device is installed in a cabinet, guaranteeing a flat and snug fit with the cabinet, and also reducing the space occupied by the entire machine after installation.

[0012] In some embodiments of this application, the evaporator fan and condenser fan are centrifugal fans; in the evaporator-side cavity, the evaporator fan is located on the air outlet side of the evaporator; in the condenser-side cavity, the condenser fan is located on the air outlet side of the condenser. Using a centrifugal fan with a flatter structure can effectively utilize the internal space of the equipment; at the same time, its high air pressure characteristics are also suitable for the internal environment with high wind resistance in a compact layout.

[0013] In some embodiments of this application, the first partition includes a first section and a second section bent and connected at a preset angle; one end of the first section is connected to the end of the evaporator; the second section is disposed adjacent to the air inlet of the evaporator fan. The first partition is generally V-shaped, which can efficiently converge and collect the airflow flowing across the entire width of the evaporator and smoothly guide it to the air inlet of the evaporator fan, thus optimizing the airflow and reducing wind resistance and noise.

[0014] In some embodiments of this application, a heat-insulating and sound-absorbing layer is provided on at least one surface of the first partition and / or the second partition. By adding a heat-insulating and sound-absorbing layer to the partition, the sound insulation capability of the compressor and the heat insulation capability of the hot and cold cavities are improved, further enhancing the overall quietness and cooling efficiency of the machine.

[0015] In some embodiments of this application, a third baffle plate has one end connected to the end of the evaporator away from the second baffle plate, and the other end connected to the side plate of the casing; a fourth baffle plate has one end connected to the end of the condenser away from the second baffle plate, and the other end connected to the side plate of the casing. By adding the third and fourth baffle plates, airflow short-circuiting or leakage can be effectively prevented, ensuring that all return airflow can pass through the heat exchanger, thus improving the overall efficiency of the unit.

[0016] In some embodiments of this application, a panel assembly is provided on the front side of the housing, the panel assembly having an evaporator-side return air inlet, a condenser-side return air inlet, and an evaporator-side air outlet; a filter device is provided inside the panel assembly, and the filter device is detachably connected to the panel assembly. The return air inlet and the cold air outlet are located on the front side of the air conditioner, facilitating embedded installation, and the air conditioner integrates a filtration function to ensure clean indoor air.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: In the kitchen air conditioning equipment described in the above embodiments, the outer casing of the condenser fan and the partition extending from it are used as part of the partition structure separating the compressor cavity and the condenser side cavity. This eliminates the need for a separate partition, which not only reduces the number of parts and simplifies the assembly process, but more importantly, it maximizes the use of internal space, making the layout of the entire equipment more compact.

[0018] Secondly, through the composite partition structure consisting of the first partition, the second partition, and the condenser fan housing, the internal space is divided into three relatively independent cavities. The compressor can be independently enclosed in the compressor cavity, and the surrounding partitions and component housings form a barrier, thereby achieving heat insulation and sound insulation for the compressor. There is no need to add additional isolation components to the compressor, further saving internal space and further reducing the overall size of the machine.

[0028] like Figures 1-10 As shown, one embodiment of this application provides a kitchen air conditioning device. Through an integrated structural design, it achieves excellent heat insulation and noise reduction for the compressor without increasing or even reducing the number of parts, while also meeting the stringent miniaturization design requirements of kitchen air conditioners.

[0029] See Figures 1-3 The kitchen air conditioning equipment mainly includes a casing 10 and a refrigeration system located inside the casing 10.

[0030] The housing 10 provides structural support and protection for the internal components of the entire air conditioner. The housing 10 consists of a top plate 11, a bottom plate 12, a side plate 13, and a back plate 14.

[0031] The refrigeration system is the core of the air conditioning cooling function, and mainly includes a compressor 23, a condenser 22, a throttling device and an evaporator 21 connected in sequence by refrigeration pipes.

[0032] Compressor 23 is the power core of the refrigeration system, responsible for compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant.

[0033] The condenser 22 is a heat exchanger where the high-temperature, high-pressure gaseous refrigerant releases heat to the surrounding environment and condenses itself into a high-pressure, medium-temperature liquid refrigerant.

[0034] Throttling devices, such as capillary tubes or expansion valves, are responsible for throttling and reducing the pressure of high-pressure liquid refrigerant, turning it into a low-temperature, low-pressure liquid refrigerant, in preparation for subsequent evaporation and heat absorption.

[0035] Evaporator 21 is another heat exchanger where low-temperature, low-pressure liquid refrigerant evaporates, absorbs heat from the surrounding environment (such as kitchen air that needs to be cooled), and becomes low-temperature, low-pressure gaseous refrigerant, which is then drawn back into compressor 23 to complete a refrigeration cycle.

[0036] The casing 10 is equipped with an evaporator-side return air inlet a and an evaporator-side outlet c. Indoor air is driven by the evaporator fan 40, drawn in from the evaporator-side return air inlet a, flows over the surface of the evaporator 21, is cooled down, and then blown out from the evaporator-side outlet c to provide cool air for the kitchen.

[0037] The casing 10 is also equipped with a condenser-side return air inlet b. Air is driven by the condenser fan 50 and drawn in from the condenser-side return air inlet b. It flows over the surface of the condenser 22, carrying away the heat released by the refrigerant and forming a high-temperature heat dissipation airflow, which is blown out from the condenser-side outlet d.

[0038] The core technical solution of this application lies in the division and partitioning method of the internal space of the casing 10.

[0039] like Figure 4 As shown, the interior of the housing 10 is divided into three independent cavities: compressor cavity B, evaporator cavity A, and condenser cavity C.

[0040] Compressor cavity B is located in the middle and is used to house compressor 23 in the refrigeration system, such as Figure 4 Yellow area.

[0041] The evaporator-side cavity A is located on one side, for example, the left side, and it houses the evaporator 21 and the evaporation fan 40. Figure 4 Blue area.

[0042] The condenser-side cavity C is located on the other side, for example, the right side, and it houses the condenser 22 and the condenser fan 50. (Example) Figure 4 Red area.

[0043] To achieve effective separation of these three cavities, a partition system is installed inside the housing 10 for separation.

[0044] like Figure 3 As shown, the partition system includes a first partition 31 and a second partition 32.

[0045] The first partition 31 is used to separate the compressor cavity B and the evaporator side cavity A.

[0046] One end edge of the first partition 31 is connected to the end of the evaporator 21, for example, to the rear edge of one side end plate of the evaporator 21; the other end can be connected to the back plate or side plate of the housing 10, thereby forming an airtight physical barrier that separates the compressor cavity B and the evaporator side cavity A.

[0047] One end of the second partition 32 is connected to the end of the evaporator 21, for example, to the front edge of one side end plate of the evaporator 21; the other end is connected to the end of the condenser 22, for example, to the front edge of one side end plate of the condenser 22.

[0048] See Figure 3 and Figure 5 The condenser fan 50 has an outwardly extending partition 52 integrally formed or additionally connected to its outer casing 51, the partition 52 pointing towards the end of the second partition 32 or the condenser 22.

[0049] The second partition 32, a portion of the housing 51 of the condenser fan 50, and the partition 52 together form a separation structure that effectively separates the compressor cavity B and the condenser side cavity C.

[0050] The aforementioned kitchen air conditioning equipment uses the outer casing 51 of the condenser fan 50 and the partition 52 extending therefrom as part of the separation structure separating the compressor cavity B and the condenser side cavity C. This eliminates the need for a separate partition, reducing the number of parts and simplifying the assembly process. More importantly, it maximizes the use of internal space, making the layout of the entire equipment more compact and enabling the miniaturization and thinning of the kitchen air conditioning equipment.

[0051] Secondly, through the composite partition structure consisting of the first partition 31, the second partition 32, and the outer shell 51 of the condenser fan 50, the internal space is divided into three relatively independent cavities. The compressor 23 can be independently enclosed in the compressor cavity B. The surrounding partitions and the outer shell 51 of the components form a barrier, thereby achieving heat insulation and sound insulation for the compressor 23. There is no need to add additional isolation components to the compressor 23, further saving internal space and further reducing the size of the whole machine.

[0052] In some embodiments, the airflow organization within the device is further simplified and integrated to maximize the use of internal space.

[0053] Specifically, in these embodiments, it is no longer necessary to set up additional, separate partitions specifically for forming the duct wall.

[0054] In the evaporator-side cavity 12, the first partition 31 itself, in addition to serving the function of separating the compressor cavity B and the evaporator-side cavity A, is also given a second function. One surface of the first partition 31 directly serves as the boundary of the evaporator-side return airflow, and together with part of the casing 10 (e.g., top plate, bottom plate or side plate), defines a complete evaporator-side return air duct.

[0055] Similarly, in the condenser side cavity C, the partition structure also serves to limit the condenser side return air duct, and together with part of the casing 10, it forms the condenser side return air duct.

[0056] By combining the functions of the chamber partition and the air duct wall into one, a high degree of structural integration is achieved. This not only further reduces the number of parts and assembly steps, but more importantly, it allows for a more compact internal layout of the entire device.

[0057] In some embodiments, the kitchen air conditioning unit also includes a water tray 60 located below the evaporator 21.

[0058] The drip tray 60 is used to collect the condensate produced by the evaporator 21 during operation due to the condensation of water vapor in the air, and to discharge it through the drain pipe.

[0059] like Figure 3 As shown, the end of the water receiving tray 60 near the condenser 22 is airtightly connected to the second partition plate 32 by screws or other means.

[0060] Because the water tray 60 has a certain depth and sidewalls, it forms a partition itself when connected to the second partition 32. This partition is located below the second partition 32 and works together with the second partition 32 and the partition structure to more completely separate the compressor cavity B from the condenser cavity C.

[0061] The water tray 60 serves as a partition structure at the bottom of the equipment while collecting water, enhancing the sealing of the cavity and eliminating the need for a potential bottom partition, thus further optimizing space utilization.

[0062] In some embodiments, such as Figure 2 As shown, the air conditioning equipment also includes an electrical control box 70, which contains electronic components such as circuit boards, relays, and sensor interfaces for controlling the operation of the equipment.

[0063] The control box 70 is fixedly installed inside the condenser side cavity C, and its position is preferably above the condenser 22.

[0064] The electrical control box 70 is positioned above the condenser 22. On the one hand, the space above the condenser 22 is usually quite open, so placing the electrical control box 70 in this space will not interfere with other large components.

[0065] On the other hand, the airflow driven by the condenser fan 50 flows through the entire condenser side cavity C, and the electrical control box 70 placed here can be naturally convectively cooled by the flowing air, which helps the electronic components inside the box to maintain a suitable operating temperature and improves the reliability of the electrical control system.

[0066] In some embodiments, such as Figure 8 As shown, the kitchen air conditioning unit also includes at least one mounting bracket 110. The mounting bracket 110 is used to fix the unit to a cabinet or wall.

[0067] On the outer surface of the housing 10, such as the back, bottom or top, a groove 15 is integrally formed by stamping.

[0068] The shape and size of the fixing bracket 110 match the groove 15.

[0069] like Figure 8 As shown, the fixed bracket 110 is an L-shaped bracket, and the groove 15 is correspondingly opened on the back and bottom surfaces of the housing 10.

[0070] During installation, the installer first fixes the mounting bracket 110 to the inner wall of the cabinet or wall surface, then pushes the kitchen air conditioner into the cabinet or hangs it on the wall, so that the groove 15 on the housing 10 is aligned and embedded with the mounting bracket 110. Finally, the mounting bracket 110 is fixed to the housing 10 from the bottom of the equipment using screws or other fasteners.

[0071] Since the entire mounting bracket 110 is embedded inside the groove 15, its highest point will not protrude from the outer surface contour of the housing 10. This allows the surface of the housing 10 to fit smoothly against the inner wall of the cabinet or wall, achieving a concealed installation effect. This not only enhances the overall aesthetics of the kitchen but also further reduces the space occupied by the entire unit.

[0072] In some embodiments, both the evaporator fan 40 and the condenser fan 50 are centrifugal fans.

[0073] Compared to common axial fans, centrifugal fans have a flatter structure, which effectively utilizes the internal space of the equipment and is more conducive to the miniaturization of the entire unit. At the same time, they can generate higher air pressure within a smaller volume, ensuring sufficient airflow through the heat exchanger.

[0074] In some embodiments, in the evaporation side cavity A, the evaporation fan 40 is located on the air outlet side of the evaporator 21.

[0075] This means that the air first flows through the evaporator 21, is cooled, and then is drawn in and sent out by the evaporator fan 40.

[0076] Compared to a blower-type layout, this exhaust-type layout allows the airflow to be more evenly distributed across the entire windward surface of the evaporator 21 when it enters, avoiding areas of concentrated airflow and thus improving heat exchange efficiency.

[0077] Similarly, in the condenser side cavity C, the condenser fan 50 is located on the air outlet side of the condenser 22, which also achieves the same effect.

[0078] In other embodiments, depending on the specific duct design and airflow and pressure requirements, the evaporator fan 40 or the condenser fan 50 may also be an axial flow fan or a mixed flow fan.

[0079] In some embodiments, see Figure 6 The first partition 31 has a specific structure and also serves to guide the return airflow.

[0080] For example, along Figure 6 As shown in the diagram, the evaporator-side chamber A, compressor chamber B, and condenser-side chamber C are arranged sequentially from left to right. The evaporator 21 is arranged along the left-right direction, located in front of the evaporator-side chamber A, and has a relatively large length to provide sufficient heat exchange area. The evaporator fan 40 (preferably a centrifugal fan) is arranged close to the left side plate of the casing 10, with its volute air inlet facing to the right (i.e., towards the interior of the casing 10).

[0081] In order to efficiently deliver the airflow from the large evaporator 21 to the fan inlet on its side, which has a much smaller opening area, the first partition 31 is designed as a one-piece bent structure.

[0082] Specifically, the first partition 31 includes a first section 311 and a second section 312 that are bent and connected at a preset angle, forming a V-shaped structure.

[0083] One end of the first section 311 is connected to the end plate of the evaporator 21 by means of screws, clips or welding; while the second section 312 is located near the air inlet of the evaporator fan 40.

[0084] The first section 311 and the second section 312, which are bent and connected, together form a guide channel for converging the airflow from the evaporator 21 and guiding it to the air inlet of the evaporator fan 40.

[0085] Specifically, the wide airflow flowing out of the entire length of the evaporator 21 is converged and guided by the inclined first section 311 when it flows towards the evaporator fan 40, and then smoothly transitions to the air inlet area aligned with the second section 312. This avoids the airflow from being chaotic and turbulent in the inlet cavity of the fan, reduces aerodynamic noise, and minimizes wind resistance loss.

[0086] In some embodiments, the connection between the first segment 311 and the second segment 312 is a smoothly transitioning arc to further reduce wind resistance.

[0087] In some embodiments, to further optimize airflow organization and prevent air leakage, such as Figure 7 As shown, a third partition 33 and a fourth partition 34 are also added inside the housing 10.

[0088] The third partition 33 is located on the outside of the evaporation side cavity A. One end of it is connected to the end of the evaporator 21 away from the second partition 32 (i.e., the left end), and the other end is connected to the side wall of the housing 10.

[0089] In this way, the third partition 33, the first partition 31, and part of the casing 10 (such as the top cover and the bottom plate) together define a clearly defined evaporator-side return air duct.

[0090] All air entering from the evaporator-side return air inlet is forcibly guided through this air duct and eventually passes through the evaporator 21, eliminating the possibility of some airflow short-circuiting from the side of the evaporator 21 to the evaporator fan 40.

[0091] Similarly, the fourth partition 34 is located on the outside of the condenser side cavity C. One end of it is connected to the end of the condenser 22 away from the second partition 32 (i.e., the right end), and the other end is connected to the side wall of the housing 10.

[0092] The fourth partition 34, together with the partition structure and part of the casing 10, defines the return air duct on the condenser side, thus preventing airflow short-circuiting.

[0093] In some embodiments, a heat-insulating and sound-absorbing layer is provided on at least one surface of the first partition and / or the second partition.

[0094] In some embodiments, please refer to Figure 1 and Figure 2 The front side of the housing 10 is provided with a panel assembly 80, which is the appearance part of the device and the human-machine interface.

[0095] The panel assembly 80 has grilles or openings for air circulation, specifically including an evaporator-side return air inlet a, a condenser-side return air inlet b, and an evaporator-side outlet air inlet c.

[0096] Evaporator-side return air vent a is used to draw in air from the kitchen for cooling. Condenser-side return air vent b is used to draw in air to dissipate heat from the condenser 22.

[0097] The evaporator-side air outlet c is used to deliver the cooled air. The evaporator-side air outlet c is located on the lower side of the panel assembly 80 and is opened along the length of the housing. The volute air outlet of the evaporator fan 40 can extend along the length of the housing to form an air outlet duct that communicates with the evaporator-side air outlet.

[0098] In some embodiments, an air guide assembly 120 is provided at the evaporator-side air outlet to control the air outlet direction.

[0099] Inside the panel assembly 80, a filter device 90 is also provided.

[0100] All air drawn in through the return air vent must first pass through the filter 90 to remove pollutants such as dust and fumes.

[0101] In some embodiments, the structure of the panel assembly 80 and the filter device 90 has been optimized in more specific ways.

[0102] The panel assembly 80 includes a panel cover 81 that serves as the main frame, and a detachably connected grille panel 82.

[0103] The panel cover 81 can be fixed to the sheet metal housing 51 by screws or other fasteners, and the display panel can be fixed on it.

[0104] The grille panel 82 integrates the return air inlet on the evaporator side and the return air inlet on the condenser side.

[0105] The grille panel 82 can be fixed to the panel cover 81 by means of a snap or magnetic structure.

[0106] For example, such as Figure 10 As shown, a buckle 822 can be provided at the lower edge of the grille panel 82, and a barb 823 can be provided at the upper edge. The grille panel 82 can be opened from the bottom and then rotated upward to be easily removed.

[0107] In some embodiments, the filtration device 90 is a multi-layer composite type, including at least a pre-filter 91 and a high-efficiency filter, such as a HEPA oil filter 92.

[0108] The pre-filter 91 is mainly used to filter larger diameter particles in the air, such as dust, hair, and catkins. The pre-filter 91 is detachably connected to the grille panel 82. After removing the grille panel 82, the user can easily remove the pre-filter 91 for washing and cleaning.

[0109] like Figure 10As shown, the primary filter 91 can be fixed and limited by its own elastic deformation through the limiting slot 821 provided on the grid panel 82.

[0110] HEPA grease filter 92 is a more efficient filter material with a special oleophobic coating. It not only filters fine particulate matter such as PM, but also effectively adsorbs and intercepts oil fumes generated during cooking. This HEPA grease filter is detachably connected to the panel cover 81. After cleaning the pre-filter 91, the user can further remove the HEPA grease filter 92 for replacement or professional cleaning.

[0111] Similarly, as Figure 9 As shown, the HEPA filter 92 can also be fixed and limited by the limiting protrusions 811 on the panel cover 81 using its own elastic deformation.

[0112] This dual, detachable filtration system design greatly facilitates daily maintenance for users in kitchens with heavy oil fumes, ensuring the long-term healthy and efficient operation of the air conditioner.

[0113] In other embodiments, the filter device 90 may also include an activated carbon filter to adsorb odors.
