[0002] With the progress of technology and the improvement of people's living standards, air conditioning equipment has been widely used in modern society. The air conditioning equipment mainly realizes the functions of refrigeration or heating through two key components, namely an evaporator and a condenser. The evaporator is responsible for absorbing the heat in the room and converting it into the latent heat of the refrigerant, thereby reducing the indoor temperature; while the condenser is responsible for releasing the heat in the refrigerant to the outside and restoring it to a liquid state to maintain the refrigeration cycle.

[0062] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0063] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0064] In addition, if the descriptions such as "first" and "second" are involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or", "or / and" or "and / or" appear throughout the text, their meanings include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0065] In the related art, an air conditioner is provided with an air inlet or an air outlet at the end wall surface. At this time, the installation position of the heat exchanger inside the air conditioner is restricted by the installation position of the air inlet or the air outlet, which will further cause an increase in the external dimensions of the air conditioner and an increase in the difficulty of the internal cavity layout of the air conditioner.

[0066] In view of this, referring to Figures 1-7 , an air conditioner 10 is provided in the embodiments of the present utility model. The air conditioner 10 can be of any suitable type. Exemplarily, the air conditioner 10 can be a kitchen air conditioner, and the kitchen air conditioner can be of a top-mounted installation form, that is, the kitchen air conditioner can be installed on the ceiling of the kitchen top and is installed in an embedded or ceiling-mounted manner. The air conditioner 10 includes a housing assembly 100 and a heat exchange assembly 200.

[0067] Referring to Figures 1-3 , the housing assembly 100 defines an accommodation chamber. One side of the housing assembly 100 is recessed towards the accommodation chamber to form a concave cavity 140 with an opening facing outwards. According to requirements, the concave cavity 140 can have any suitable cross-sectional shape. For example, the concave cavity 140 can be in the shape of a rectangular body, a spherical body, a trapezoidal body, or any regular or irregular cavity shape. The accommodation chamber includes a first chamber 111 on one side of the concave cavity 140 and a second chamber 127 on the other side of the concave cavity 140. The housing assembly 100 includes a first plate body 115 located between the first chamber 111 and the concave cavity 140 and a second plate body 124 located between the second chamber 127 and the concave cavity 140. It can be understood that the first plate body 115 can partition the first chamber 111, and the second plate body 124 can partition the second chamber 127.

[0068] Referring to Figures 1-3, the heat exchange component 200 includes a first heat exchanger 210 and a second heat exchanger 220 that communicate with each other. The first heat exchanger 210 is disposed in the first chamber 111, and the second heat exchanger 220 is disposed in the second chamber 127. Among them, both the first heat exchanger 210 and the second heat exchanger 220 are used for heat exchange. For the convenience of description, the heat exchangers described in the present utility model are all represented as the first heat exchanger 210 and / or the second heat exchanger 220. Specifically, the heat exchanger in the present utility model may be an evaporator.

[0069] Particularly, the first plate body 115 is provided with a first air guide port 112 that communicates the concave cavity 140 with the first chamber 111; and / or, the second plate body 124 is provided with a second air guide port 121 that communicates the concave cavity 140 with the second chamber 127. It can be understood that the first air guide port 112 can be used for the air flow between the concave cavity 140 (and the external environment communicated with the concave cavity 140) and the first chamber 111, and the second air guide port 121 can be used for the air flow between the concave cavity 140 (and the external environment communicated with the concave cavity 140) and the second chamber 127. Based on the above air guide ports, on the one hand, when the first plate body 115 is provided with the first air guide port 112, only a part of the first chamber 111 and the concave cavity 140 can be communicated by the first air guide port 112, and the parts outside the first air guide port 112 are all separated by the first plate body 115. The same can be set when the second plate body 124 is provided with the second air guide port 121; on the other hand, when the first plate body 115 is provided with the first air guide port 112 and the second plate body 124 is not provided with the second air guide port 121, the concave cavity 140 and the second chamber 127 can be separated by the second plate body 124. When the second plate body 124 is provided with the second air guide port 121 and the first plate body 115 is not provided with the first air guide port 112, the concave cavity 140 and the first chamber 111 can be separated by the first plate body 115. For the convenience of description, the air guide ports described in the present utility model are all represented as the first air guide port 112 and / or the second air guide port 121.

[0070] Combining the setting of the air guide port with the setting of the housing assembly 100 and the heat exchange component 200, see Figures 1-3It can be understood that since the first chamber 111 and the second chamber 127 are respectively provided on both sides of the concave cavity 140, and the first heat exchanger 210 and the second heat exchanger 220 are respectively arranged in the first chamber 111 and the second chamber 127, the arrangement of the concave cavity 140 enables the air flow in the external environment (the external environment in the present invention all refers to the area outside the air conditioner 10) to be introduced from the concave cavity 140 and then further introduced into the first chamber 111 and / or the second chamber 127. Thus, on the one hand, the first heat exchanger 210 and the second heat exchanger 220 can be arranged according to the position of the groove 132 and do not have to be arranged close to the end wall surface of the housing assembly 100. In other words, the arrangement positions of the first heat exchanger 210 and the second heat exchanger 220 are not restricted by the air inlet and outlet of the air conditioner 10, making the internal space layout of the housing assembly 100 more flexible and conducive to reducing the overall size of the air conditioner 10. On the other hand, since the concave cavity 140 is located between the first chamber 111 and the second chamber 127, and a first plate body 115 is provided between the concave cavity 140 and the first chamber 111, and a second plate body 124 is provided between the concave cavity 140 and the second chamber 127, the above arrangement can play a certain role in separating the first chamber 111 and the second chamber 127. Taking the embodiment where the first plate body 115 is provided with the first air guide opening 112 as an example, based on the separating effect of the above arrangement, when it is necessary to introduce the air flow from the concave cavity 140 into the first chamber 111, the second chamber 127 can be prevented from affecting the above air supply effect, thereby making the air supply effect better.

[0071] It can be seen that the air conditioner 10 of the present invention includes a housing assembly 100 and a heat exchange assembly 200. The housing is provided with a concave cavity 140, and the first chamber 111 and the second chamber 127 are respectively provided on both sides of the concave cavity 140. The first heat exchanger 210 and the second heat exchanger 220 are respectively arranged in the first chamber 111 and the second chamber 127. Thus, the first plate body 115 is provided with a first air guide opening 112 communicating the concave cavity 140 with the first chamber 111; and / or, the second plate body 124 is provided with a second air guide opening 121 communicating the concave cavity 140 with the second chamber 127. Compared with the related art in which the air inlet or outlet is arranged at the end wall surface and the heat exchanger is correspondingly arranged at the position of the air inlet or outlet, the solution of the present invention can, on the one hand, enable the first heat exchanger 210 and the second heat exchanger 220 to be arranged according to the position of the groove 132 and do not have to be arranged close to the end wall surface of the housing assembly 100, and on the other hand, can play a certain role in separating the first chamber 111 and the second chamber 127 to avoid the connected first chamber 111 and the second chamber 127 from affecting the air flow. Therefore, the solution of the present invention can make the internal space layout of the air conditioner 10 more flexible and the air supply effect better.

[0072] Referring to the figures, for ease of description, the following will take the embodiment in which the first plate body 115 is provided with a first air guide opening 112 and the second plate body 124 is provided with a second air guide opening 121 as an example. Different embodiments can be combined with different technical solutions.

[0073] For the specific structure of the housing assembly 100, refer to Figures 1-3 , in some embodiments, the housing assembly 100 includes a base 130, a first housing 110, and a second housing 120. The first housing 110 and the second housing 120 are connected to the same side of the base 130. Among them, the connection between the first housing 110 and the second housing 120 and the base 130 can be a detachable connection (specifically, it can be a snap connection), or it can be a non-detachable connection (specifically, it can be an integrally formed connection). Based on this, in some embodiments, the first housing 110 and the base 130 jointly define a first chamber 111, and the second housing 120 and the base 130 jointly define a second chamber 127, that is, the first housing 110 and the second housing 120 can both be connected to the base 130 and are shells extending in a ring shape (the shape is not limited). In addition, the side plate of the first housing 110 facing the second housing 120 is the first plate body 115, the side plate of the second housing 120 facing the first housing 110 is the second plate body 124, and the first housing 110 and the second housing 120 can be arranged at intervals and the gap between them is the concave cavity 140. In other embodiments, the first housing 110 can also be integrally connected to the second housing 120, and the two are partially spaced apart to define the concave cavity 140. In other words, the first housing 110 and the second housing 120 can be two parts of the same housing connected together.

[0074] Refer to Figures 1-3 , for ease of description, the following defines the direction from the first plate body 115 to the second plate body 124 as the first direction X, the direction from the first housing 110 to the base 130 as the second direction Y, and the third direction Z is perpendicular to the first direction X and the second direction Y.

[0075] Based on the housing assembly 100 described in the above embodiments. Refer to Figures 1-3In some embodiments, the first heat exchanger 210 includes a first heat exchange portion 211, which is disposed on one side of the first chamber 111 near the first plate 115. When viewed along the first direction X, the first heat exchange portion 211 at least partially overlaps with the first air guide port 112. In other words, along the first direction X, the projection of the first heat exchange portion 211 on a projection plane perpendicular to the first direction X and the projection of the opening edge of the first air guide port 112 on the projection plane at least partially overlap. It can be understood that the first heat exchange portion 211 is a portion of the first heat exchanger 210 for receiving the airflow introduced by the concave cavity 140 and / or for introducing the airflow in the first chamber 111 into the concave cavity 140, and thus, the first heat exchange portion 211 can be an opening. Therefore, the above arrangement can ensure that the first heat exchange portion 211 is directly opposite to the first air guide port 112 along the opening direction of the first air guide port 112, so that the air supply can be smoother.

[0076] Further, other plates of the first housing 110 may also be configured. Figures 4-7 In some embodiments, the first shell 110 further includes a third plate 116 located on one side of the third direction Z, and the third plate 116 is provided with a third air guide port 113 connected to the first chamber 111. Therefore, in addition to the air intake from the first air guide port 112 along the first direction X, the air intake from the third air guide port 113 along the third direction Z can also be provided to the first chamber 111, so that the air intake direction of the first chamber 111 can have more options, or the air intake volume can be larger, which is beneficial to improve the air guiding effect. Based on this, in some embodiments, the first heat exchanger 210 includes a second heat exchange part 212, and the second heat exchange part 212 is located on one side of the first chamber 111 close to the third plate 116. When viewed along the third direction Z, the third air guide port 113 at least partially overlaps with the second heat exchange part 212. Similarly, on the other hand, see Figures 4-7 In some embodiments, the first shell 110 also includes a fourth plate 117 located on the side away from the second shell 120, and the fourth plate 117 is provided with a fourth air duct 114 connected to the first chamber 111. The first heat exchanger 210 includes a third heat exchange part 213, and the third heat exchange part 213 is located on a side of the first chamber 111 close to the fourth plate 117. When observed along the first direction X, the third heat exchange part 213 at least partially overlaps with the fourth air duct 114.

[0077] Regarding the above two aspects of the settings, it can be understood that the second heat exchange part 212 is the part of the first heat exchanger 210 for receiving the air flow introduced by the third air guide opening 113 and / or for discharging the air flow in the first chamber 111 from the third air guide opening 113, and the third heat exchange part 213 is the part of the first heat exchanger 210 for receiving the air flow introduced by the fourth air guide opening 114 and / or for discharging the air flow in the first chamber 111 from the third air guide opening 113. The difference between the second heat exchange part 212 (or the third air guide opening 113) and the third heat exchange part 213 (or the fourth air guide opening 114) can lie in the different installation positions. Therefore, the specific form and installation of the second heat exchange part 212 can refer to the first heat exchange part 211 of the above embodiments. Thus, the above settings can ensure that the second heat exchange part 212 faces the third air guide opening 113 along the opening direction of the third air guide opening 113, and the third heat exchange part 213 faces the fourth air guide opening 114 along the opening direction of the fourth air guide opening 114, thereby making the air supply smoother.

[0078] To provide power for the air supply of the air conditioner 10, refer to Figures 4-7 , in some embodiments, the air conditioner 10 further includes a first air supply assembly 300 disposed in the first chamber 111. Based on this, for the setting of the introduced gas, in some embodiments, the first air supply assembly 300 is configured to generate the power for making the outside air be introduced into the first chamber 111 from the first air guide opening 112. In addition, according to requirements, the air flow can also be introduced into the first chamber 111 by using the openings formed on other plates of the housing assembly 100. On the other hand, for the setting of the discharged gas, in some embodiments, the base 130 is provided with a fifth air guide opening 131 communicating with the first chamber 111, and the first air supply assembly 300 is configured to generate the power for making the air in the first chamber 111 be discharged from the first chamber 111 through the fifth air guide opening 131. In addition, according to requirements, the air flow in the first chamber 111 can also be discharged by using the openings formed on other plates of the housing assembly 100. It should be noted that due to the above functions, the first air supply assembly 300 can adopt any suitable form for air supply, and no limitation is made here.

[0079] Regarding the specific layout of the first heat exchanger 210, refer to Figures 4-7, in some embodiments, the first heat exchanger 210 includes a first heat exchange part 211, a second heat exchange part 212, and a third heat exchange part 213. The first heat exchange part 211 is disposed on one side of the first chamber 111 close to the first plate body 115, the third heat exchange part 213 is disposed on one side of the first chamber 111 far from the first plate body 115, the second heat exchange part 212 is disposed between the first heat exchange part 211 and the third heat exchange part 213, and the second heat exchange part 212 is respectively communicated with the same side of the first heat exchange part 211 and the third heat exchange part 213 along the third direction Z. In addition, the first heat exchange part 211, the second heat exchange part 212, and the third heat exchange part 213 can be communicated with each other. It can be seen that the first heat exchange part 211 and the third heat exchange part 213 are respectively located on both sides of the first chamber 111 along the first direction X, and the second heat exchange part 212 is located on one side of the first chamber 111 along the third direction Z. Thus, the first heat exchange part 211, the second heat exchange part 212, and the third heat exchange part 213 can jointly form a "U" - shaped structure, and the three can be respectively close to the air guide openings of the plate bodies they face, so that the structure of the first heat exchanger 210 can be relatively compact, and it does not occupy too much space in the first chamber 111, and a large heat exchange area can be realized in a limited space.

[0080] Further, referring to Figures 4-7 , in some embodiments, the air conditioner 10 further includes an electric control box 500, and the electric control box 500 is disposed in the first chamber 111 and on the side of the first chamber 111 opposite to the second heat exchange part 212. It can be understood that in combination with the first heat exchanger 210 having a "U" - shaped structure in the above - mentioned embodiment, at this time, the electric control box 500 can be disposed on the side not covered by the first heat exchanger 210, that is, the side where the notch of the "U" - shaped structure is located. With the above - mentioned arrangement, the layout of the first chamber 111 can be made more compact, and the interference between the first heat exchanger 210 and the electric control box 500 can be avoided.

[0081] In addition, referring to Figure 3, in some embodiments, the dimension of the first housing 110 along the third direction Z is greater than the dimension of the first housing 110 along the first direction X. It can be understood that the above setting makes the first housing 110 in a strip structure with a larger size at one end and a smaller size at the other end, which is more conducive to the internal space layout of the first chamber 111. Specifically, in some embodiments, the above setting is beneficial to arranging the fan (especially when there are multiple fans, they can be arranged oppositely along the third direction Z), and makes the air outlet long and narrow, with better air outlet uniformity. More specifically, the first housing 110 can be in a rectangular shape. Combining with the position arrangement of the first heat exchange part 211, the second heat exchange part 212 and the third heat exchange part 213 in the above embodiments, when observing along the second direction Y, the length dimensions of the first heat exchange part 211 and the third heat exchange part 213 are longer, and the length dimension of the second heat exchange part 212 is shorter. Generally speaking, the above setting can maximize the total length of the first heat exchange part 211, the second heat exchange part 212 and the third heat exchange part 213, that is, can maximize the heat exchange area of the first heat exchanger 210, making the heat exchange effect better. The overall shape of the first heat exchanger 210 is a long "U" - shaped structure with a longer size, which makes its overall height increase by 12% compared with the short "U" - shaped structure, and the total air inlet area increases by 12%. At the same time, it also makes the air suction at the position where the first heat exchanger 210 is located uniform, and significantly improves the fan performance.

[0082] In some embodiments, various types of fans can be used in the first air supply assembly 300 and the second air supply assembly 400, such as axial - flow fans, cross - flow fans, etc. Different fan types are suitable for different working environments according to their characteristics. Axial - flow fans are suitable for larger air volumes, while cross - flow fans are more suitable for smaller spaces and have lower noise.

[0083] Based on the first heat exchange part 211, the second heat exchange part 212 and the third heat exchange part 213 defined in the above embodiments, corresponding settings can also be made for the air supply assembly. See Figures 4-7, in some embodiments, the first air supply component 300 is disposed in the first chamber 111 and between the first heat exchange part 211 and the third heat exchange part 213. The first air supply component 300 includes a first motor 310, a first fan blade and a second fan blade. The first motor 310 includes a rotating shaft, one end of the rotating shaft is connected to the first fan blade, and the other end is connected to the second fan blade to drive the first fan blade and the second fan blade to rotate simultaneously. The first air supply component 300 is located between the electric control box 500 and the second heat exchange part 212, the first fan blade is arranged close to the second heat exchange part 212, and the second fan blade is arranged close to the electric control box 500. It can be understood that the first air supply component 300 includes the first fan blade and the second fan blade arranged oppositely along the third direction Z. The first motor 310 can drive both of them simultaneously, and the first fan blade and the second fan blade are respectively responsible for driving the air flow around the second heat exchange part 212 and the air flow around the electric control box 500, so that the air supply effect of the first air supply component 300 is better and acts uniformly on both sides of the first chamber 111 along the third direction Z.

[0084] Regarding the structure of the air supply component, more specifically, in some embodiments, the first air supply component 300 includes a fan blade and a guide cover. The fan blade is disposed in the first chamber 111, and the guide cover is disposed around the fan blade to guide the air flow through the first heat exchanger 210. The fan blade rotates to generate an air flow, and after being guided by the guide cover, the air flow exchanges heat with the first heat exchanger 210, improving the heat exchange efficiency. The setting of the guide cover makes the air flow more concentrated, effectively improves the air flow distribution, ensures that the air flow passes through the first heat exchanger 210 evenly, and enhances the heat exchange effect; the second air supply component 400 also includes a fan blade and a guide cover. The fan blade is disposed in the second chamber 127, and the guide cover is disposed around the fan blade to guide the air flow through the second heat exchanger 220. The fan blade rotates to generate an air flow, and after being guided by the guide cover, the air flow exchanges heat with the second heat exchanger 220, improving the heat exchange efficiency. The setting of the guide cover makes the air flow more concentrated, effectively improves the air flow distribution, ensures that the air flow passes through the second heat exchanger 220 evenly, and enhances the heat exchange effect.

[0085] Further, referring to Figures 4-7 , in some embodiments, the second heat exchanger 220 is disposed on the side of the second chamber 127 away from the first housing 110. The above setting can extend the air flow path corresponding to the second heat exchanger 220 to make the air supply effect better and is more convenient for the spatial layout in the second chamber 127.

[0086] Further, referring to Figures 4-7 , in some embodiments, the air conditioner 10 further includes a second air supply component 400 disposed in the second chamber 127. The second air supply component 400 is located on the side of the second heat exchanger 220 close to the first housing 110. The above setting can extend the air flow path corresponding to the second heat exchanger 220 to make the air supply effect better.

[0087] It should be noted that the relevant settings of the first housing 110 (including the settings and layouts of various components inside the first chamber 111) in the above embodiments can be applied to the second housing 120 in the same way and have similar effects, which will not be elaborated here.

[0088] For the setting of introducing gas into the second chamber 127, refer to Figures 4-7 , in some embodiments, the second housing 120 includes a fifth plate body 125 located on the side facing away from the first housing 110. The fifth plate body 125 is provided with a sixth air guide opening 122. The air conditioner 10 further includes a second air supply assembly 400 disposed in the second chamber 127. The second air supply assembly 400 is configured to generate a power for introducing outside air into the second chamber 127 through the sixth air guide opening 122. On the other hand, for the setting of discharging gas from the second chamber 127, refer to Figures 4-7 , in some embodiments, the second housing 120 includes a sixth plate body 126 located on one side along the third direction Z. The sixth plate body 126 is provided with a seventh air guide opening 123. The air conditioner 10 further includes a second air supply assembly 400 disposed in the second chamber 127. The second air supply assembly 400 is configured to generate a power for discharging the air in the second chamber 127 out of the second chamber 127 through the seventh air guide opening 123. Combining the above two aspects of settings, the air in the second chamber 127 can be introduced into the second chamber 127 through the sixth air guide opening 122 on the side of the second housing 120 along the first direction X and discharged through the seventh air guide opening 123 on the side of the second housing 120 along the third direction Z along an "L" - shaped trajectory, so as to make the air supply effect better.

[0089] In order to make the first heat exchanger 210 and the second heat exchanger 220 cooperate better, refer to Figures 4-7 , in some embodiments, the side of the base 130 facing the gap is provided with a groove 132 that is in communication with the first chamber 111, the gap, and the second chamber 127. Based on this, in some embodiments, the heat exchange assembly 200 further includes an intermediate pipeline 230. The intermediate pipeline 230 is disposed in the groove 132, and one end extends into the first chamber 111 and is connected to the first heat exchanger 210, and the other end extends into the second chamber 127 and is connected to the second heat exchanger 220. It can be understood that the intermediate pipeline 230 can connect the first heat exchanger 210 and the second heat exchanger 220, so that the refrigerant can flow between the two heat exchangers. Therefore, the design of the intermediate pipeline 230 should consider the reliability of its connection and the smoothness of fluid flow. The pipeline material can be selected as corrosion - resistant and pressure - resistant materials, such as copper pipes or stainless steel pipes, etc., to ensure the stability of long - term operation. The connection between the intermediate pipeline 230 and the heat exchanger should be well - sealed to prevent refrigerant leakage.

[0090] For the intermediate pipeline 230 and the groove 132 arranged as described above, more specifically, in some embodiments, part or all of the intermediate pipeline 230 is placed in the groove 132 to facilitate the layout and maintenance of the pipeline. The design of the groove 132 can effectively hide the intermediate pipeline 230, prevent the pipeline from being exposed outside, and thus improve the aesthetics and safety of the air conditioner 10.

[0091] It can be understood that, in some embodiments, the cross-sectional shape of the groove 132 can be rectangular, circular, oval, etc., and is selected according to the actual size and shape of the intermediate pipeline 230. The depth and width of the groove 132 need to match the intermediate pipeline 230 to ensure that the pipeline can be stably installed in the groove 132 and prevent the pipeline from loosening or falling off due to vibration or other reasons.

[0092] A sealing strip can be provided at the edge of the groove 132 to play a sealing role when the intermediate pipeline 230 is installed in the groove 132, and prevent condensed water or other substances from entering the groove 132 and affecting the working performance of the intermediate pipeline 230. The sealing strip can be made of rubber or silicone material and has good elasticity and durability.

[0093] Supporting members can be provided inside the groove 132 to increase the structural strength of the groove 132 and prevent the groove 132 from deforming due to the weight of the intermediate pipeline 230. The supporting members can be metal sheets or plastic sheets, and their shapes and sizes need to be adapted to the groove 132. By providing the supporting members, the pressure of the intermediate pipeline 230 on the groove 132 can be effectively dispersed, and the service life of the groove 132 can be extended.

[0094] A cover plate can be provided at the opening of the groove 132. The cover plate can be fixed to the groove 132 by means of buckles or screws, etc., to facilitate opening the cover plate for inspection and maintenance of the intermediate pipeline 230 when needed. The material of the cover plate can be selected to be the same as that of the plastic layer to maintain the consistency of the appearance of the air conditioner 10.

[0095] Through the design of the above embodiments, the groove 132 can not only effectively hide the intermediate pipeline 230 and improve the aesthetics of the air conditioner 10, but also ensure the stability and reliability of the intermediate pipeline 230 through structures such as sealing strips and supporting members. At the same time, it facilitates the maintenance and replacement of the pipeline, and improves the practicality and user experience of the air conditioner 10.

[0096] In some embodiments, the air conditioner 10 satisfies at least one of the following conditions;

[0097] a), Along the first direction X, the width dimension A1 of the first housing 110 satisfies: 260 mm ≤ A1 ≤ 300 mm, for example, A1 is 260 mm, 270 mm, 280 mm, 290 mm, 300 mm, etc.;

[0098] b), along the first direction X, the width dimension A2 of the second housing 120 satisfies: 260 mm ≤ A2 ≤ 300 mm, for example, A2 is 260 mm, 270 mm, 280 mm, 290 mm, 300 mm, etc.;

[0099] c), along the second direction Y, the height dimension B1 of the base 130 satisfies: 20 mm ≤ B1 ≤ 80 mm, for example, B1 is 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc., for example, B1 is 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc.;

[0100] d), along the third direction Z, the length dimension C1 of the first housing 110 satisfies: 500 mm ≤ C1 ≤ 600 mm, for example, C1 is 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, 600 mm, etc.;

[0101] e), along the third direction Z, the length dimension C2 of the second housing 120 satisfies: 500 mm ≤ C2 ≤ 600 mm, for example, C2 is 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, 600 mm, etc.;

[0102] e), along the first direction X, the spacing L between the first housing 110 and the second housing 120 satisfies: 20 mm ≤ L ≤ 50 mm. For example, L is 20 mm, 30 mm, 40 mm, 50 mm, etc.

[0103] The width dimension A1 of the first housing 110 is between 260 mm and 300 mm, and the width dimension A2 of the second housing 120 is also between 260 mm and 300 mm. Such a dimension design enables the first housing 110 and the second housing 120 to provide sufficient space to accommodate the heat exchange component 200 and other internal components, while ensuring that the overall volume of the air conditioner 10 is moderate, facilitating installation and maintenance.

[0104] The height dimension B1 of the base 130 is between 20 mm and 80 mm. Such a height design ensures the structural stability of the base 130, and at the same time provides sufficient support for the first housing 110 and the second housing 120, enabling the entire air conditioner 10 to be firmly installed in the required position.

[0105] The length dimension C1 of the first housing 110 is between 500 mm and 600 mm, and the length dimension C2 of the second housing 120 is also between 500 mm and 600 mm. Such a length design ensures that there is sufficient space inside the first housing 110 and the second housing 120 to place the heat exchanger and other components, and at the same time makes the overall shape of the air conditioner 10 more coordinated, facilitating installation in various environments.

[0106] The distance L between the first housing 110 and the second housing 120 is between 20 mm and 50 mm. Such a length design can, to a certain extent, avoid the mutual interference between the gas at the first chamber 111 and the gas at the second chamber 127 while ensuring the air supply effect.

[0107] It can be understood that in some embodiments, the selection of the width dimensions A1 and A2 of the first housing 110 and the second housing 120 should not only consider the layout requirements of the internal components, but also the overall design and aesthetics of the air conditioner 10. For example, if the width dimensions of the first housing 110 and the second housing 120 are designed too wide, it may occupy too much space resources, and if too narrow, it may affect the layout and heat dissipation effect of the internal components. Therefore, selecting a width dimension between 260 mm and 300 mm is a relatively ideal balance point.

[0108] In addition to meeting the structural stability, the height dimension B1 of the base 130 should also consider the aesthetics of the air conditioner 10 after installation. Too high or too low a height of the base 130 may make the air conditioner 10 look less coordinated. Therefore, selecting a height dimension between 20 mm and 80 mm can ensure the structural stability of the base 130 while also making the overall air conditioner 10 look more beautiful.

[0109] The selection of the length dimensions C1 and C2 of the first housing 110 and the second housing 120 needs to comprehensively consider factors such as the performance requirements of the air conditioner 10, the layout of the internal components, and the appearance design. Too short a length dimension may not meet the layout requirements of all components, while too long may cause the air conditioner 10 to occupy too much space. Selecting a length dimension between 500 mm and 600 mm can ensure sufficient internal space without making the air conditioner 10 look too bulky.

[0110] Through the design of the above dimensions, not only is the reasonable layout of the internal components of the air conditioner 10 ensured, but also the structural stability and appearance aesthetics of the air conditioner 10 are ensured, improving the user experience. Especially when the air conditioner 10 is a kitchen air conditioner and the kitchen air conditioner is suspended, the design of the above dimensions can achieve better results.

[0111] It should be noted that the air conditioner 10 in any of the above embodiments is suitable for installation on the ceiling.

[0112] An embodiment of the third aspect of the present utility model provides an air conditioner 10 assembly, which includes the air conditioner 10 of any of the foregoing embodiments. The air conditioner 10 assembly further includes a connecting member, one end of the connecting member is connected to the air conditioner 10, and the other end is adapted to be connected to the ceiling to suspend the air conditioner 10. Specifically, the air conditioner 10 can be suspended from the ceiling, and it can abut against the ceiling or be arranged at an interval from the ceiling. In one embodiment, the air conditioner 10 assembly can be used in an indoor space with a suspended ceiling. The suspended ceiling boards are connected under the ceiling of the room. After the air conditioner 10 is suspended from the ceiling, the first housing 110 and the second housing 120 are basically located in the compartment between the suspended ceiling board and the ceiling. The base 130 of the air conditioner 10 is basically flush with the position of the suspended ceiling board, or slightly above the suspended ceiling board, or slightly below the suspended ceiling board. In a further embodiment, the air conditioner 10 assembly can be suspended from the kitchen ceiling. Since hot air rises during cooking in the kitchen, the heat at the position of the air conditioner 10 is relatively high, and it is more necessary to insulate the first heat exchanger 210 and the second heat exchanger 220, thereby improving the refrigeration efficiency of the air conditioner 10.

[0113] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the application concept of the present utility model, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present utility model.
