Description

Technical Field

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

[0002] Kitchen air conditioners are a new type of kitchen air conditioner specifically designed for cooling the kitchen. They have a compact structure, and in order to improve heat exchange performance while placing the evaporator in a very narrow internal space, the evaporator generally adopts a V-shaped structure.

[0003] The evaporator described above includes two heat exchange components arranged at an angle. The refrigerant flow direction in these components directly affects the cooling effect on the gas. To facilitate piping installation, the liquid inlet and outlet of the evaporator are typically located at the top. To prevent liquid slugging in the compressor, the refrigerant near the outlet needs to be completely vaporized. During evaporator installation, the air inlet of the heat exchange components is also located at the top, close to the liquid outlet. This area has a large airflow. Since the fully vaporized refrigerant no longer has the ability to cool the gas, some gas enters the fan uncooled, resulting in poor overall cooling performance.

[0004] Therefore, there is an urgent need to research a kitchen air conditioner to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a kitchen air conditioner to solve the problem in the prior art where the refrigerant inside the heat exchange component has completely vaporized and has no cooling capacity in areas with large air volume, resulting in poor overall cooling effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Kitchen air conditioner, including:

[0008] The casing is equipped with an air inlet;

[0009] The evaporator includes two heat exchange components arranged in a V-shape. An air inlet is formed at the maximum distance between the two heat exchange components, and an air outlet is formed at the minimum distance between them. The air inlet is sealed and connected to the air outlet. Airflow enters between the two heat exchange components from the air inlet, part of which flows out through the heat exchange components on both sides, and part of which flows out through the air outlet. The flow rate of gas out of the air outlet is the minimum.

[0010] A fan is disposed inside the housing and located at the end of the evaporator away from the air inlet;

[0011] The refrigerant inlet and refrigerant outlet of the heat exchange component are arranged at intervals, and the distance between the refrigerant outlet and the air outlet of the heat exchange component is closer than that between the refrigerant inlet and the air outlet.

[0012] As an optional technical solution for kitchen air conditioning, the heat exchange component includes several pipes arranged at intervals. The refrigerant inlet of the heat exchange component is located in one of the pipes, and the refrigerant outlet of the heat exchange component is located in another pipe. The several pipes are connected end to end in sequence. The pipe with the refrigerant outlet of the heat exchange component is located at the air outlet.

[0013] As an optional technical solution for kitchen air conditioning, the heat exchange component also includes two fixing members, which are arranged at intervals along the extension direction of the pipeline. One end of all pipelines is fixed to one of the fixing members, and the other end is fixed to the other fixing member.

[0014] As an optional technical solution for kitchen air conditioning, several pipes in the same heat exchange component form at least three pipe groups. Several pipes in each pipe group are arranged at intervals along the length of the fixing component, and several pipe groups are arranged at intervals along the width of the fixing component. The pipe with the refrigerant outlet of the heat exchange component is located in the outermost pipe group.

[0015] As an optional technical solution for kitchen air conditioning, the refrigerant inlet pipe with heat exchange components is located in the outermost pipe group and is located at the position closest to the air inlet. Along the refrigerant flow direction, the pipes in each pipe group are connected in sequence, and the pipe groups are connected in sequence from the outside to the inside.

[0016] As an optional technical solution for kitchen air conditioning, the inner diameter of the pipes in different pipe groups increases sequentially from the outer to the inner side of the two heat exchange components; and / or,

[0017] The pipeline has a variable diameter structure, with the inner diameter of the same pipeline gradually increasing along the refrigerant flow direction.

[0018] As an optional technical solution for kitchen air conditioning, the evaporator also includes two sealing components, both of which are disposed between the two heat exchange components and form a ventilation channel with the two heat exchange components. The two ends of the ventilation channel form the air inlet and air outlet, respectively.

[0019] As an optional technical solution for kitchen air conditioning, the kitchen air conditioning also includes a sealing gasket, which is sandwiched between the housing and the evaporator and surrounds the outer periphery of the air inlet.

[0020] As an optional technical solution for kitchen air conditioning, the heat exchange component includes several pipes arranged at intervals, and the evaporator also includes several fins. The several fins are arranged at intervals along the extension direction of the pipes, and part of them are located in the air outlet.

[0021] As an optional technical solution for kitchen air conditioning, the included angle between the two sets of heat exchange components ranges from 30° to 50°.

[0022] This utility model has at least the following beneficial effects:

[0023] This utility model provides a kitchen air conditioner, which includes a casing, an evaporator, and a fan. The casing has an air inlet; the evaporator includes two heat exchange components arranged in a V-shape, with the air inlet formed at the maximum distance between the two components and the air outlet formed at the minimum distance between them; the air inlet and the evaporator are sealed together, and airflow enters between the two heat exchange components from the air inlet, partially passing through the heat exchange components on both sides and exiting through the air outlet; the fan is located inside the casing at the end of the evaporator furthest from the air inlet; the refrigerant inlet and refrigerant outlet of the heat exchange components are arranged alternately, with the refrigerant outlet of the heat exchange components being closer to the air outlet than the refrigerant inlet. The above configuration ensures that after the gas enters the housing through the air inlet, it enters the area between the two heat exchange components. Most of the gas then passes through the two heat exchange components and flows towards the fan, while a small portion flows towards the fan through the air outlet. This results in a smaller airflow at the air outlet, and the refrigerant outlet of the heat exchange component is close to the air outlet. This ensures that the refrigerant has undergone sufficient heat exchange and converted into a gaseous state before flowing out of the heat exchange components, while also preventing a large amount of gas from directly entering the fan without undergoing heat exchange, thus improving the overall heat exchange efficiency.

[0037] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0038] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0040] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0041] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0042] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0043] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0044] like Figures 1 to 6As shown, this embodiment provides a kitchen air conditioner, which includes a housing 100, an evaporator 200, and an evaporator 200. The housing 100 is provided with an air inlet 110; the evaporator 200 includes two heat exchange components 210 arranged in a V-shape, with the air inlet 201 formed at the maximum distance between the two heat exchange components 210 and the air outlet 202 formed at the minimum distance between them; the air inlet 201 is sealed and connected to the air inlet 110, and the airflow enters between the two heat exchange components 210 from the air inlet 201, part of which flows out through the heat exchange components 210 on both sides, and part of which flows out through the air outlet 202; the fan 300 is located inside the housing 100 and at the end of the evaporator 200 away from the air inlet 110; the refrigerant inlet 2111 and refrigerant outlet 2112 of the heat exchange components 210 are arranged at intervals, and the distance between the refrigerant outlet 2112 and the air outlet 202 is closer than that between the refrigerant inlet 2111 and the air outlet 202. Specifically, the gas flow rate through the heat exchange component 210 is greater than the gas flow rate at the outlet 202. The gas flow rate is minimum at the outlet 202.

[0045] The above configuration ensures that after the gas enters the housing 100 through the air inlet 110, it enters the area between the two heat exchange components 210 through the air inlet 201. Then, most of the gas passes through the two heat exchange components and flows to the fan 300, while a small portion of the gas flows to the fan 300 through the air outlet 202. This results in a smaller airflow at the air outlet 202, and the refrigerant outlet 2112 of the heat exchange component 210 is close to the air outlet 202. This ensures that the refrigerant has undergone sufficient heat exchange and converted into a gaseous state when it flows out of the heat exchange component 210, while also preventing a large amount of gas from directly entering the fan 300 without undergoing heat exchange, thus improving the overall heat exchange efficiency.

[0046] The kitchen air conditioner also includes a drip tray, which is located below the air outlet 202 and between the air outlet 202 and the fan 300. The drip tray is used to receive condensate produced by the evaporator 200. At the same time, the drip tray will interfere with the airflow to a certain extent, further reducing the gas flow rate from the air outlet 202.

[0047] The heat exchange assembly 210 includes several spaced-apart pipes 211. The refrigerant inlet 2111 of the heat exchange assembly 210 is located in one of the pipes 211, and the refrigerant outlet 2112 of the heat exchange assembly 210 is located in another pipe 211. The pipes 211 are connected end-to-end in sequence. The pipe 211 with the refrigerant outlet 2112 is located at the air outlet 202. This arrangement extends the flow path of the refrigerant, thereby increasing the contact area with the gas and improving the heat exchange effect. Simultaneously, the location of the pipe 211 with the refrigerant outlet 2112 at the air outlet 202 results in a smaller airflow through this pipe 211, ensuring complete vaporization of the internal refrigerant while minimizing gas waste and improving the overall cooling effect. The pipe 211 with the refrigerant outlet 2112 is designed as a superheater pipe. It should be noted that excessive gas flow through the superheater pipe would lead to waste and affect the cooling effect.

[0048] The heat exchange assembly 210 also includes two fixing members 212, which are arranged at intervals along the extension direction of the pipe 211. One end of each pipe 211 is fixed to one of the fixing members 212, and the other end is fixed to the other fixing member 212. This arrangement effectively fixes the pipe 211, preventing sloshing during gas flow. The fixing members 212 are screwed to the housing 100 to improve the stability of the connection between the evaporator 200 and the housing 100.

[0049] In some embodiments, a plurality of pipes 211 in the same heat exchange component 210 form at least three pipe groups 214. The plurality of pipes 211 in each pipe group 214 are spaced apart along the length of the fixing member 212, and the plurality of pipe groups 214 are spaced apart along the width of the fixing member 212. The pipe 211 with the refrigerant outlet 2112 of the heat exchange component 210 is located in the outermost pipe group 214. This arrangement places the pipe 211 with the refrigerant outlet 2112 at the position furthest from the air inlet 110 and with the smallest airflow, ensuring complete vaporization of the internal refrigerant while improving the overall cooling effect. The ultimate goal of this embodiment is to place the pipe 211 with the refrigerant outlet 2112 of the heat exchange component 210 at the position with the smallest airflow, thereby avoiding airflow waste and improving the cooling effect. In other embodiments, the specific location with the minimum air volume can be determined by simulation based on the arrangement structure of the heat exchange components 210, the relative positional relationship between the heat exchange components 210 and the air inlet 110, and the relative positional relationship between the heat exchange components 210 and the fan 300. The simulation method is well known to those skilled in the art, so it will not be described in detail here.

[0050] Among them, along the refrigerant flow direction, there are two pipes 211 upstream of the pipe 211 with refrigerant outlet 2112 and the pipe 211 with refrigerant outlet 2112. All three pipes 211 are located at the lower end of the heat exchange assembly 210, with the pipe 211 with refrigerant outlet 2112 located on the outermost side. It should be noted that the two heat exchange assemblies 210 are arranged in a V-shape to form a V-groove, with the part near the middle of the V-groove being the inner part and the part near the edge of the V-groove being the outer part.

[0051] The refrigerant inlet 2111 of the heat exchange assembly 210 is located in the outermost pipe group 214 and is positioned closest to the air inlet 110. Along the refrigerant flow direction, the pipes 211 in each pipe group 214 are sequentially connected, and the pipe groups 214 are connected sequentially from the outside to the inside. This arrangement ensures that the refrigerant temperature in the outermost pipe group 211 is the lowest. When the gas flows through several pipe groups 214 and finally reaches the outermost pipe group 214, its temperature is relatively low, thus being closer to the temperature of the refrigerant in the outermost pipe group 211, which facilitates improved heat exchange efficiency.

[0052] In some embodiments, the inner diameter of the pipes 211 in different pipe groups 214 increases sequentially from the outer to the inner side of the two heat exchange components 210. The pipes 211 are straight tubes, and all pipes 211 in the same pipe group 214 have the same inner diameter. In other embodiments, the pipes 211 are straight tubes, and the inner diameter of all pipes 211 in the same pipe group 214 increases sequentially along the refrigerant flow direction. This arrangement facilitates the adaptation that the pressure in the pipes 211 does not change significantly during gas vaporization, and helps to reduce the flow velocity, thereby improving heat exchange efficiency. Furthermore, the straight tubes 211 are easy to manufacture and have low cost.

[0053] Pipe 211 has a variable diameter structure, with the inner diameter of the same pipe 211 gradually increasing along the refrigerant flow direction. This design can further improve the coordinated change of the inner diameter of pipe 211 and the internal air pressure, ensuring controllable refrigerant flow velocity and improving heat exchange efficiency.

[0054] Multiple pipes 211 in adjacent pipe groups 214 are staggered along the gas flow direction so that the gas flow path when passing through the heat exchange component 210 is S-shaped.

[0055] To further improve heat exchange efficiency, in some embodiments, the evaporator 200 further includes a plurality of fins 213, which are spaced apart along the extension direction of the pipe 211 and partially located within the air outlet 202. This arrangement allows gas to pass through the heat exchange assembly 210 through the gap between two adjacent fins 213, thereby enabling uniform heat exchange of the gas.

[0056] The evaporator 200 also includes two sealing elements 220, which are disposed between the two heat exchange components 210 and form a ventilation channel with the two heat exchange components 210. The two ends of the ventilation channel form an air inlet 201 and an air outlet 202, respectively. In other words, a V-shaped groove is formed between the two heat exchange components 210, and the two sealing elements 220 are respectively sealed at both ends of the V-shaped groove, so that the gas can only flow out through the heat exchange components 210 and avoids flowing out from the openings at both ends of the V-shaped groove, thereby improving the heat exchange efficiency. At the same time, it also avoids setting a sealing structure on the shell 100, thereby improving the adaptability of the evaporator 200 to different structures of the shell 100.

[0057] Furthermore, the kitchen air conditioner also includes a sealing gasket sandwiched between the housing 100 and the evaporator 200, and surrounding the outer periphery of the air inlet 110. This arrangement ensures that gas entering the housing 100 can only enter the area between the two heat exchange components 210 through the air inlet 201, preventing it from bypassing the evaporator 200 and flowing towards the fan 300. The sealing gasket can be made of rubber or silicone. When there is a pre-tightening force between the evaporator 200 and the housing 100, the sealing gasket is compressed and undergoes elastic deformation, thereby maintaining a good sealing effect.

[0058] The included angle α between the two sets of heat exchange components 210 ranges from 30° to 50°. This arrangement helps to increase the contact area between the gas and the two heat exchange components 210, thereby improving the heat exchange efficiency; at the same time, this arrangement can accommodate a larger air inlet 110, thereby meeting the cooling demand for higher power.

[0059] Combination Figure 6 As shown, in other embodiments, the evaporator 200 further includes two through pipes 230, and the heat exchange assembly 210 has three tube groups 214. One through pipe 230 is connected between the outlet of the first tube group 214 in the first heat exchange assembly 210 and the inlet of the second tube group 214 in the second heat exchange assembly 210, and the second tube group 214 in the second heat exchange assembly 210 communicates with the third tube group 214. The other through pipe 230 is connected between the outlet of the first tube group 214 in the second heat exchange assembly 210 and the inlet of the second tube group 214 in the first heat exchange assembly 210. The second tube group 214 in the first heat exchange assembly 210 communicates with the third tube group 214.

[0060] The evaporator 200 also includes a siphon tube 240, which connects the two through tubes 230, and the inner diameter of the siphon tube 240 is smaller than the inner diameter of the through tubes 230. The inner diameter of the siphon tube 240 is 1.5 mm to 2.5 mm; preferably 2 mm.

[0061] The main inlet pipe 410 is connected to two branch inlet pipes 420 via a tee pipe. The two branch inlet pipes 420 are respectively connected to the two refrigerant inlets 2111 of the two heat exchange components 210. The main outlet pipe 440 is connected to two branch outlet pipes 430 via a tee pipe. The two branch outlet pipes 430 are respectively connected to the refrigerant outlets 2112 of the two heat exchange components 210 to ensure that the flow rate of refrigerant entering each heat exchange component 210 is the same.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
