Description

Technical Field

[0001] This disclosure relates to the field of electrical technology, and in particular to an air conditioner. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, air conditioners have gradually become an indispensable household appliance. Air conditioners can deliver temperature-regulating gas to provide users with a comfortable environment.

[0003] In related technologies, air conditioners typically use a fan located inside the unit to deliver temperature-regulating gas during operation. To meet the airflow requirements of the air conditioner, the fan power is usually increased to improve the airflow. However, this increases the noise generated by the fan during operation, resulting in increased noise levels in the air conditioner and affecting the user experience. Utility Model Content

[0004] In view of this, the present disclosure provides an air conditioner that solves the technical problem of excessive noise generated during the operation of the air conditioner.

[0005] Specifically, this disclosure is achieved through the following technical solution.

[0006] According to a first aspect of the present disclosure, an air conditioner is provided, comprising a housing assembly, a heat exchange assembly, and a cross-flow fan. The housing assembly has a heat exchange chamber and an air inlet and an air outlet communicating with the heat exchange chamber. The heat exchange assembly is disposed within the heat exchange chamber and located between the air inlet and the air outlet. The heat exchange assembly includes multiple heat exchange elements. The cross-flow fan includes a cross-flow impeller disposed within the heat exchange chamber, located between the heat exchange assembly and the air outlet, and the multiple heat exchange elements are sequentially bent and connected to partially surround the cross-flow impeller. The diameter of the cross-flow impeller is D, wherein 112mm ≤ D ≤ 130mm.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] When this air conditioner is operating, the heat exchange components within the heat exchange chamber exchange heat. Positioning these components between the air inlet and outlet allows for heat exchange with the incoming air, and the temperature-regulating gas is then output through the outlet. A cross-flow fan creates a controlled airflow of the temperature-regulating gas within the heat exchange chamber. A cross-flow impeller, located between the heat exchange components and the outlet, further enhances airflow between the heat exchange chamber and the outlet, increasing the rate at which the temperature-regulating gas is delivered to the outlet. The heat exchange components consist of multiple heat exchange elements, which are sequentially bent and connected to partially surround the cross-flow impeller. This design improves heat exchange with the incoming air and facilitates the delivery of the exchanged gas to the outlet via the cross-flow impeller. Furthermore, it optimizes the internal structure of the air conditioner, resulting in a more compact design. This optimized internal structure allows for a larger internal space, enabling the cross-flow impeller diameter (D) to be designed to be 112mm ≤ D ≤ 130mm. By designing the diameter of the cross-flow fan impeller to be 112mm≤D≤130mm, a larger diameter is achieved, thereby increasing airflow while maintaining the overall size of the air conditioner. Furthermore, a larger cross-flow fan can operate at a lower speed to achieve the target airflow, which helps reduce noise.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0031] With the development of society and the economy and the improvement of people's living standards, air conditioners have gradually become an indispensable household appliance. Air conditioners can deliver temperature-regulating gas to provide users with a comfortable environment.

[0032] In related technologies, air conditioners typically use a fan located inside the unit to deliver temperature-regulating gas during operation. To meet the airflow requirements of the air conditioner, the fan power is usually increased to improve the airflow. However, this increases the noise generated by the fan during operation, resulting in increased noise levels in the air conditioner and affecting the user experience.

[0033] As a household appliance, air conditioners are becoming increasingly popular due to their ability to provide a comfortable environment. However, with a wide variety of types and brands available, consumers have many choices. Therefore, how to win over consumers and enhance product competitiveness has become a growing concern for air conditioner manufacturers.

[0034] Based on this, the present disclosure provides an air conditioner that solves the technical problem of excessive noise generated during the operation of the air conditioner.

[0035] like Figure 1 As shown, an air conditioner 100 is provided, which is capable of providing temperature-regulating gas.

[0036] It should be noted that the air conditioner 100 can provide temperature-regulating gas, including providing cold air to cool the room and providing hot air to heat the room, etc.

[0037] It should be noted that there are many types of air conditioners, including wall-mounted units, floor-standing units, and ducted units, etc.

[0038] like Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, the air conditioner 100 includes a housing assembly 110, a heat exchange assembly 120, and a cross-flow fan 130. The housing assembly 110 has a heat exchange chamber 111 and an air inlet 112 and an air outlet 113 communicating with the heat exchange chamber 111. The heat exchange assembly 120 is disposed within the heat exchange chamber 111 and is located between the air inlet 112 and the air outlet 113. The heat exchange assembly 120 includes multiple heat exchange elements. The cross-flow fan 130 includes a cross-flow impeller 131 disposed within the heat exchange chamber 111. The cross-flow impeller 131 is located between the heat exchange assembly 120 and the air outlet 113, and the multiple heat exchange elements are sequentially bent and connected to partially surround the cross-flow impeller 131. The diameter of the cross-flow impeller 131 is D, where 112mm ≤ D ≤ 130mm.

[0039] Thus, when the air conditioner 100 is working, the heat exchange component 120 in the heat exchange chamber 111 can exchange heat. By placing the heat exchange component 120 between the air inlet 112 and the air outlet 113, the heat exchange component 120 can exchange heat with the air entering through the air inlet 112 and output temperature-regulating gas through the air outlet 113. The cross-flow fan 130 enables the temperature-regulating gas in the heat exchange chamber 111 to form an airflow with a certain velocity. Utilizing the cross-flow fan wheel 131 located in the heat exchange chamber 111 between the heat exchange component 120 and the air outlet 113, airflow is formed between the heat exchange chamber 111 and the air outlet 113, thereby increasing the rate at which the temperature-regulating gas is delivered to the air outlet 113. The heat exchange assembly 120 includes multiple heat exchange elements, which are sequentially bent and connected to partially surround the cross-flow fan 131. This allows for better heat exchange of the gas entering through the air inlet 112, and the heat-exchanged gas is then transported to the air outlet 113 via the cross-flow fan 131. Furthermore, it optimizes the internal structure of the air conditioner 100, making it more compact. By optimizing the internal structure, the internal space is increased, allowing the diameter D of the cross-flow fan 131 to be designed to be 112mm ≤ D ≤ 130mm. By designing the diameter of the cross-flow fan 131 to be 112mm ≤ D ≤ 130mm, a larger diameter is achieved, thus increasing airflow while maintaining the overall size of the air conditioner 100. Moreover, at the target airflow rate, a larger cross-flow fan 130 can operate at a lower speed, which helps reduce noise.

[0040] In some embodiments, 116mm ≤ D ≤ 128mm.

[0041] In some embodiments, 116mm ≤ D ≤ 125mm.

[0042] In some embodiments, 116mm ≤ D ≤ 122mm.

[0043] In other embodiments, 112mm ≤ D ≤ 120mm.

[0044] In other embodiments, 122mm ≤ D ≤ 125mm.

[0045] It should be noted that the diameter D of the cross-flow impeller 131 can be implemented in various ways, including D values ​​of 112mm, 113mm, 114mm, 115mm, 116mm, 117mm, 118mm, 119mm, 120mm, 121mm, 122mm, 123mm, 124mm, 125mm, 126mm, 127mm, 128mm, 129mm, and 130mm, etc. The specific setting can be determined according to actual needs, and will not be elaborated further here.

[0046] It should be noted that the size of the air conditioner 100 can be implemented in various ways, including 1 horsepower, 1.5 horsepower, and 2 horsepower, etc.

[0047] In the prior art, the fan blades of a conventional air conditioner 100 typically have a diameter of 90mm-108mm. However, the cross-flow fan 131 of the air conditioner 100 of this application has a diameter of 112mm≤D≤130mm. This means that compared to the prior art air conditioner 100 with a large fan diameter, this application is advantageous in increasing air volume and reducing noise during operation.

[0048] like Figure 2 as well as Figure 3 As shown, in some embodiments, the plurality of heat exchangers includes a first heat exchanger 121, which extends along the height direction of the housing assembly 110. The shortest distance from the outer contour of the cross-flow impeller 131 to the first heat exchanger 121 is L, where L < 0.5D. Thus, by extending the first heat exchanger 121 along the height direction of the housing assembly 110, the first heat exchanger 121 is disposed within the heat exchange chamber 111. By designing the shortest distance L from the outer contour of the cross-flow fan 131 to the first heat exchanger 121 to be less than 0.5D, that is, the shortest distance from the outer contour of the cross-flow fan 131 to the first heat exchanger 121 to be less than the radius of the cross-flow fan 131, the distance between the first heat exchanger 121 and the outer contour of the cross-flow fan 131 can be reduced, making the internal structure of the air conditioner 100 more compact and giving it more internal space. This ensures that the size of the cross-flow fan 131 can be increased without changing the overall size of the air conditioner 100, thereby increasing the air volume of the air conditioner 100. Furthermore, when meeting the target air volume, the cross-flow fan 130 can have a lower rotation speed, which is beneficial for reducing noise.

[0049] It should be noted that the shortest distance from the outer contour of the cross-flow impeller 131 to the first heat exchanger 121 is Figure 3 As shown in the figure, the shortest distance is the distance from the outer contour of the cross-flow impeller 131 to the end point of the first heat exchanger 121 that is closest to it, perpendicular to the first heat exchanger 121.

[0050] It should be noted that the height direction of the housing assembly 110 is... Figure 3 The X direction is shown.

[0051] It should be noted that the heat exchange component 120 can be implemented in various ways, including as an evaporator, etc.

[0052] like Figure 2 as well as Figure 3As shown, in some embodiments, 0.09D ≤ L ≤ 0.16D. Thus, by designing the shortest distance L from the outer contour of the cross-flow fan 131 to the first heat exchanger 121 to be 0.09D ≤ L ≤ 0.16D, the distance between the first heat exchanger 121 and the cross-flow fan 131 can be further reduced, thereby increasing the internal space of the air conditioner 100. While ensuring the normal operation of the cross-flow fan 130, the internal space of the air conditioner 100 can be further increased without increasing the overall size of the air conditioner 100. This allows for ensuring the airflow of the entire unit and reducing the noise during operation by increasing the size of the cross-flow fan 130, thereby improving the user experience and comfort of the air conditioner 100.

[0053] Combining 112mm≤D≤130mm, we can obtain that the dimensional range of 0.09D≤L≤0.16D is 10mm≤L≤21mm. In the prior art, the shortest distance from the outer contour of the fan blades to the evaporator in a conventional air conditioner 100 is more than 22mm. The air conditioner 100 of this application reduces the shortest distance from the outer contour of the cross-flow fan 131 to the first heat exchange element 121, thereby allowing the air conditioner 100 to have a larger internal space, which is beneficial for designing a larger diameter cross-flow fan 131.

[0054] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.10D≤L≤0.15D.

[0055] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.12D≤L≤0.14D.

[0056] It should be noted that there are multiple ways to implement L, including L being 0.09D, 0.10D, 0.11D, 0.12D, 0.13D, 0.14D, 0.15D, and 0.16D, etc. The specific setting can be made according to actual needs, and will not be elaborated further here.

[0057] like Figure 2 as well as Figure 3As shown, in some embodiments, the multiple heat exchangers include a first heat exchanger 121, which extends along the height direction of the housing assembly 110. The housing assembly 110 includes a sidewall 114, which is parallel to the first heat exchanger 121. The distance from the first heat exchanger 121 to the sidewall 114 is K, where K < 0.5D. Thus, by designing the distance K from the first heat exchanger 121 to the sidewall 114 to be less than 0.5D, that is, the distance from the first heat exchanger 121 to the sidewall 114 is less than the radius of the cross-flow fan 131, the distance between the first heat exchanger 121 and the sidewall 114 can be reduced, making the internal structure of the air conditioner 100 more compact and providing more internal space. This ensures that the size of the cross-flow fan 131 can be increased without changing the overall size of the air conditioner 100, thereby increasing the air volume of the air conditioner 100. Furthermore, when meeting the target air volume, the cross-flow fan 130 can have a lower rotation speed, which helps to reduce noise.

[0058] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.12D ≤ K ≤ 0.20D. Thus, by designing the distance K from the first heat exchanger 121 to the side wall 114 to be 0.12D ≤ K ≤ 0.20D, the distance between the first heat exchanger 121 and the side wall 114 can be further reduced, making the internal structure of the air conditioner 100 more compact and further increasing the internal space of the air conditioner 100. While ensuring the normal operation of the cross-flow fan 130, the internal space of the air conditioner 100 can be further increased without increasing the overall size of the air conditioner 100. This allows for ensuring the airflow of the entire unit and reducing the noise during operation by increasing the size of the cross-flow fan 130, thereby improving the user experience and comfort of the air conditioner 100.

[0059] Combining 112mm≤D≤130mm, we can obtain that the dimensional range of 0.12D≤K≤0.20D is 13mm≤K≤26mm. In the prior art, the distance from the evaporator to the side wall 114 of a conventional air conditioner 100 is more than 27mm. The air conditioner 100 of this application reduces the distance from the evaporator to the side wall 114, thereby allowing the air conditioner 100 to have a larger internal space, which is beneficial for designing a larger diameter cross-flow fan impeller 131.

[0060] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.14D≤K≤0.20D.

[0061] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.14D≤K≤0.18D.

[0062] It should be noted that there are multiple ways to implement K, including K being 0.12D, 0.13D, 0.14D, 0.15D, 0.16D, 0.17D, 0.18D, 0.19D, and 0.20D, etc. The specific setting can be made according to actual needs, and will not be elaborated further here.

[0063] like Figure 2 as well as Figure 3 As shown, in some embodiments, the shortest distance L from the outer contour of the cross-flow fan 131 to the first heat exchanger 121 and the distance K from the first heat exchanger 121 to the side wall 114 satisfy: L < K. Thus, by designing the distance from the first heat exchanger 121 to the side wall 114 to be greater than the shortest distance from the outer contour of the cross-flow fan 131 to the first heat exchanger 121, the distance from the first heat exchanger 121 to the side wall 114 at the air inlet position can be made larger, ensuring a more sufficient airflow into the first heat exchanger 121, thereby increasing the airflow in the air-conditioned room.

[0064] like Figure 2 as well as Figure 3 As shown, in some embodiments, along the height direction of the housing assembly 110, the outer contour of the cross-flow impeller 131 includes an upper endpoint 1311 at the top and a lower endpoint 1312 at the bottom, and the first heat exchanger 121 includes an upper edge 1211 at the top and a lower edge 1212 at the bottom. The upper edge 1211 is not lower than the upper endpoint 1311 along the height direction of the housing assembly 110. Thus, by designing the upper edge 1211 of the first heat exchanger 121 to be not lower than the upper endpoint 1311 of the top of the outer contour of the cross-flow impeller 131, the upper edge 1211 of the first heat exchanger 121 can be higher than or parallel to the upper endpoint 1311 of the cross-flow impeller 131 along the height direction of the housing assembly 110, which is beneficial to improving the heat exchange effect of the first heat exchanger 121 on the incoming air.

[0065] like Figure 2 as well as Figure 3 As shown, in some embodiments, the lower edge 1212 is not higher than the lower end point 1312 along the height direction of the housing assembly 110. Thus, by designing the lower edge 1212 of the first heat exchanger 121 at the bottom to be not lower than the lower end point 1312 of the bottom of the outer contour of the cross-flow impeller 131, it is possible that the lower edge 1212 of the first heat exchanger 121 is lower than or parallel to the lower end point 1312 of the cross-flow impeller 131 in the height direction of the housing assembly 110, which is beneficial to improving the heat exchange effect of the first heat exchanger 121 on the incoming air.

[0066] It should be noted that, along the height direction of the housing assembly 110, the positional relationship between the first heat exchanger 121 and the cross-flow fan 131 can be that the upper edge 1211 is not lower than the upper end point 1311 and the lower edge 1212 is not higher than the lower end point 1312, or the upper edge 1211 is not lower than the upper end point 1311 and the lower edge 1212 is not higher than the lower end point 1312.

[0067] like Figure 2 as well as Figure 3 As shown, in some embodiments, along the height direction of the housing assembly 110, the upper edge 1211 is not lower than the upper end point 1311, while the lower edge 1212 is not higher than the lower end point 1312. This allows the height dimension of the first heat exchanger 121 to be larger than the diameter of the cross-flow fan 131 along the height direction of the housing assembly 110, which is beneficial for the first heat exchanger 121 to surround the cross-flow fan 131, thereby further improving the heat exchange effect of the first heat exchanger 121.

[0068] like Figure 2 as well as Figure 3 As shown, in some embodiments, the height dimension of the first heat exchanger 121 along the height direction of the housing assembly 110 is S, where 0.85D≤S≤1.1D. Thus, by designing the height dimension S of the first heat exchanger along the height direction of the housing assembly 110 to be 0.85D≤S≤1.1D, the size of the first heat exchanger 121 can be adapted to the size of the cross-flow fan 131, which is beneficial to improving the efficiency of heat exchange using the first heat exchanger 121 and increasing the airflow rate. Furthermore, while satisfying the above effects, the size of the first heat exchanger 121 can be controlled, preventing the first heat exchanger 121 from being too large and occupying excessive internal space in the air conditioner 100.

[0069] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.9D≤S≤1.05D.

[0070] like Figure 2 as well as Figure 3 As shown, in some embodiments, 0.95D≤S≤1.0D.

[0071] It should be noted that the height dimension S of the first heat exchanger 121 can be implemented in various ways, including S being 0.85D, 0.86D, 0.87D, 0.88D, 0.89D, 0.90D, 0.91D, 0.92D, 0.93D, 0.94D, 0.95D, 0.96D, 0.97D, 0.98D, 0.99D, 1.0D, 1.01D, 1.02D, 1.03D, 1.04D, 1.05D, 1.06D, 1.07D, 1.08D, 1.09D, and 1.1D, etc. The specific setting can be determined according to actual needs, and will not be elaborated further here.

[0072] like Figure 2 as well as Figure 3 As shown, in some embodiments, the multiple heat exchange components include a first heat exchange component 121, a second heat exchange component 122, and a third heat exchange component 123. The first heat exchange component 121 is connected to the housing assembly 110, and the third heat exchange component 123 is connected to the housing assembly 110. One end of the second heat exchange component 122 is bent and connected to the first heat exchange component 121, and the other end is bent and connected to the third heat exchange component 123. In this way, by sequentially bending and connecting the first heat exchange component 121, the second heat exchange component 122, and the third heat exchange component 123 and placing them in the heat exchange cavity 111 to surround part of the cross-flow impeller 131, the heat exchange efficiency and heat exchange effect of the heat exchange assembly 120 can be improved.

[0073] like Figure 2 as well as Figure 3 As shown, in some embodiments, the air inlet 112 and the air outlet 113 are spaced apart along the height direction of the housing assembly 110. In this way, by spaced apart the air inlet 112 and the air outlet 113 along the height direction of the housing assembly 110, the air conditioner 100 can draw in and exit air vertically along the height direction of the housing assembly 110, which helps to improve the air intake and exhaust effect of the air conditioner 100.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
