[001] This application claims priority to the Patent Application Chinese Patent No. 202110636362.X, entitled “AIR CONDITIONER,” filed with the China National Intellectual Property Administration on June 8, 2021, the full content of which is incorporated herein by reference. FIELD
[002] The present invention relates to the field of air conditioning technologies and, more specifically, to an air conditioner. BACKGROUND
[003] Electrical controls, such as a motor drive module, will generate heat during use. In the related technique, a heat dissipation member is placed in an electrical control box. However, the heat dissipation member has a low heat dissipation efficiency, which fails to effectively meet the heat dissipation demand of the electrical controls and the interior of the electrical control box, easily resulting in damage to the electrical controls. SUMMARY
[004] The present invention aims to solve at least one of the problems of the art in the related art.
[005] With this aim, the present invention provides an air conditioning device.
[006] According to embodiments of this invention, an air conditioner is provided. The air conditioner includes: a housing with a fan cavity and a heat exchange cavity communicating with each other; an electrical control box disposed in the housing and communicating with the heat exchange cavity and the fan cavity; an electrical control disposed in the electrical control box; and an assembly. Petition 870230097790, dated 06 / 11 / 2023, page 19 / 61 2 / 35 of the fan is arranged in the fan cavity. The fan assembly is configured to supply air to the heat exchange cavity and dissipate heat from the electrical control box.
[007] The air conditioner according to the embodiments of the present invention includes the housing, the electrical control box, the electrical control, and the fan assembly. In one direction of air supply of the air conditioner, the housing has the fan cavity and the heat exchange cavity communicating with each other. The electrical control box is disposed in the housing and is in communication with the heat exchange cavity and the fan cavity. The electrical control is disposed in the electrical control panel and the electrical control box and can ensure that the entire air conditioner is operated under control. The fan assembly is positioned in the fan cavity and is configured to supply air to the heat exchange cavity during operation.
[008] In an exemplary embodiment, the fan assembly may supply air to the heat exchange cavity during operation, which increases the pressure in the heat exchanger cavity to be greater than the pressure in the electrical control box and the pressure in the fan cavity. Therefore, during air conditioner operation, due to a pressure difference between the heat exchange cavity and the electrical control box, an airflow in the heat exchange cavity at least partially flows into the electrical control box, and returns to the fan cavity after passing through the electrical control box. During air conditioner use, the electrical control will generate heat, and thus the temperature inside the electrical control box will increase. The high temperature will easily result in damage to the electrical control and affect the service life of the electrical control.Therefore, the airflow passing through the electrical control box can effectively dissipate heat from the control box. Petition 870230097790, dated 06 / 11 / 2023, page 20 / 61 3 / 35 electrical and electrical control within the electrical control box, which can ensure proper temperature in the electrical control box and a reduction in the temperature of the electrical control. In this way, the safe use of the electrical control box can be guaranteed.
[009] Furthermore, during the operation of the air conditioner according to the present invention, the air in the heat exchange cavity flows into the electrical control box, while the fan assembly can continuously supply air to the heat exchange cavity during its operation. As a result, the pressure in the heat exchange cavity is increased in order to be greater than the pressure in the electrical control box and the pressure in the fan cavity. Therefore, in the present invention, the volume of air entering the electrical control box can be significantly increased to enhance the thermal dissipation effect in the electrical control box and the electrical control in the electrical control box. Therefore, the present invention has a better thermal dissipation effect compared to a solution in the related art where the electrical control box is cooled by using air from an external environment.Furthermore, since an airflow driven by the fan assembly has a relatively low temperature, the airflow in the heat exchange cavity can cool the electrical control in the electrical control box to some extent as it passes through the electrical control box, which further reduces the temperature of the electrical control, ensuring the service life of the electrical control.
[0010] Therefore, in the present invention, a circulating flow path can be formed within the air conditioner, allowing an airflow in the fan cavity to flow into the heat exchange cavity and, at least partially, flow into the electrical control box and then back into the fan cavity through the electrical control box. Therefore, efficient heat dissipation from the electrical control box is achieved. Petition 870230097790, dated 06 / 11 / 2023, page 21 / 61 4 / 35 through partial airflow can be achieved, ensuring a longer service life for each of the electrical control boxes and the electrical control unit.

[0012] In the above-mentioned solutions, the electrical control box has a first heat dissipation hole communicating with the heat exchange cavity and a second heat dissipation hole communicating with the fan cavity. After flowing into the heat exchange cavity, an airflow in the fan cavity at least partially flows into the electrical control box through the first heat dissipation hole and flows back into the fan cavity through the second heat dissipation hole.
[0013] In some possible implementations, the air conditioner additionally includes an air duct for heat dissipation, connecting the heat exchange cavity and the electrical control box.
[0014] In some possible implementations, the air conditioning unit additionally includes a mounting beam and a support member. The mounting beam is located at a connection between the fan cavity and the heat exchange cavity. The support member is located in the heat exchange cavity. The air duct for heat dissipation is located between the mounting beam and the support member.
[0015] In some possible implementations, the electrical control box is located on a lateral side of the fan cavity. The air duct for heat dissipation is arranged transversely to the air supply direction of the fan mount.
[0016] In some possible implementations, a gap is formed between an inlet end of the air duct for heat dissipation and an outlet end of the fan cavity. The support member has an arc-shaped conductor surface located at the end. Petition 870230097790, dated 06 / 11 / 2023, page 22 / 61 5 / 35 of the thermal dissipation duct inlet.
[0017] In some possible implementations, the air conditioner additionally includes a heat exchanger disposed in the heat exchange cavity. The heat dissipation air duct has an inlet end located on one side of the heat exchanger facing the fan mount. After flowing into the heat exchange cavity, an airflow in the fan cavity at least partially flows into the heat dissipation air duct to exchange heat with the heat exchanger.
[0018] In some possible implementations, the housing additionally includes a piping cavity isolated from the heat exchange cavity by the support member. The heat dissipation air duct is located between the piping cavity and the electrical control box.
[0019] In any of the above implementations, the air conditioner additionally includes an air duct hood disposed in the fan cavity. The air duct hood is configured to direct the airflow toward the heat exchange cavity.
[0020] In any of the above implementations, the air duct hood has an air supply outlet positioned toward the heat exchange cavity.

[0021] In any of the above implementations, the air duct hood has an air intake arranged to face a return air intake from the fan cavity. The electrical control box is located on a side of the air duct hood and in communication with the fan cavity.
[0022] In any of the above implementations, the fan cavity has an air return inlet. The heat exchange cavity Petition 870230097790, dated 06 / 11 / 2023, page 23 / 61 6 / 35 has an air outlet. The air passages are located between the return air inlet and the air outlet. The electrical control box is arranged on one side of the air passages and is in communication with some of the air passages in the heat exchange cavity.

DETAILED DESCRIPTION OF THE MODALITIES
[0033] To clarify and explain the objectives, features, and advantages mentioned above of the present invention, the present invention will be further described in detail below, in combination with the accompanying drawings and specific embodiments. It is worth noting that the embodiments of the present invention and the features in the embodiments can be combined with each other without any conflict.
[0034] In the following description, many specific details are provided to facilitate a complete understanding of the present invention. However, the present invention can additionally be implemented in other ways different from those described in the present invention. Therefore, the scope of the present invention is not limited by the specific embodiments described below.
[0035] An air conditioner according to some embodiments of the present invention will be described below with reference to Figure 1 through Figure 5. The dashed arrows in Figure 1 and Figure 2 represent the direction of Petition 870230097790, dated 06 / 11 / 2023, page 25 / 61 8 / 35 airflow.
[0036] As illustrated in Figure 1, Figure 2 and Figure 3, according to a first embodiment of the present invention, an air conditioner is provided. The air conditioner includes a housing 102, an electrical control box 108, an electrical control 110 and a fan assembly 112.
[0037] As illustrated in Figure 1 and Figure 2, in the air supply direction of the air conditioner, housing 102 has a fan cavity 104 and a heat exchange cavity 114 communicating with each other. The electrical control box 108 is located in housing 102. The electrical control box 108 is in communication with a heat exchange cavity 106. The electrical control 110 is located in the electrical control box 108 and can ensure that the entire air conditioner is operated under control. The fan assembly 112 is located in the fan cavity 104 and can supply air to the heat exchange cavity 106 during operation.
[0038] In a further embodiment, as illustrated in Figure 1 and Figure 2, the fan assembly 112 is configured to supply air to the heat exchange cavity 106 during operation, which increases the pressure in the heat exchange cavity 106 so that it is greater than the pressure in the electrical control box 108. As a result, during the operation of the air conditioner, due to a pressure difference between the heat exchange cavity 106 and the electrical control box 108, an airflow in the heat exchange cavity 106 at least partially flows into the electrical control box 108 and then flows back into the fan cavity 104 after passing through the electrical control box 108.
[0039] During the use of the air conditioner, the electrical control 110 will generate heat, and thus the temperature in the electrical control box 108 will rise. The high temperature will easily result in damage to the electrical control. Petition 870230097790, dated 06 / 11 / 2023, page 26 / 61 9 / 35 110 and will affect the service life of the electrical control 110. Therefore, the airflow passing through the electrical control box 108 can effectively dissipate heat from the electrical control box 108 and the electrical control 110 into the electrical control box 108, which can ensure a suitable temperature in the electrical control box 108 and a temperature reduction of the electrical control 110. Therefore, it is possible to ensure the safe use of the electrical control box 108 and the electrical control 110.
[0040] Furthermore, during the operation of the air conditioner according to the embodiments of the present invention, the air in the heat exchange cavity 106 flows into the electrical control box 108, while the fan assembly 112 can continuously supply air to the heat exchange cavity 106 during its operation. In this way, the pressure in the heat exchange cavity 106 is greater than the pressure in the electrical control box 108 and the pressure in the fan cavity 104. Therefore, in this embodiment, it is possible to significantly increase the volume of air flowing into the electrical control box 108 to improve the heat dissipation effect in the electrical control box 108 and in the electrical control 110 in the electrical control box 108. When compared with a solution in the art where the electrical control box is cooled by using air from an external environment in the related art, the heat dissipation effect is better in the present invention.
[0041] Furthermore, since an airflow driven by the fan assembly 112 has a relatively low temperature, the airflow in the heat exchange cavity 106 can cool the electrical control 110 in the electrical control box 108 to some extent as it enters the electrical control box 108, which further reduces the temperature of the electrical control 110, ensuring the service life of the electrical control 110.
[0042] Therefore, with the air conditioner according to the modality, a circulating flow path can be formed within the Petition 870230097790, dated 06 / 11 / 2023, page 27 / 61 10 / 35 air conditioner to allow an airflow in the fan cavity 104 to flow into the heat exchange cavity 106 to at least partially flow into the electrical control box 108 and then flow back to the fan cavity 104 through the electrical control box 108, and thus this part of the airflow can ensure that the electrical control box 108 is in communication with the heat exchange cavity 106. During operation, the pressure in the heat exchange cavity 106 is greater than the pressure in the electrical control box 108 and the pressure in the fan cavity 104, which allows the airflow in the heat exchange cavity 106 to flow continuously through the electrical control box 108. Therefore, effective heat dissipation from the electrical control box 108 and the electrical control 110 can be achieved.
[0043] According to a second embodiment of the present invention, an air conditioner is provided.
[0044] Furthermore, based on the first embodiment, the electrical control box 108 has a first heat dissipation hole 120 and a second heat dissipation hole 124, as illustrated in Figure 4 and Figure 5. The first heat dissipation hole 120 is in communication with the heat exchange cavity 106, which ensures that the airflow in the heat exchange cavity 106 can flow to the electrical control box 108. The second heat dissipation hole 124 is in communication with the fan cavity 104, which ensures that the airflow in the electrical control box 108 can flow to the fan cavity 104. In this way, a circulating flow path can be formed between the fan cavity 104, the heat exchange cavity 106, and an electrical control cavity to continuously dissipate heat from the electrical control box 108 and the electrical control 110 into the electrical control box 108 during operation. of the air conditioner.
[0045] In an additional mode, during the operation of Petition 870230097790, dated 06 / 11 / 2023, p. 28 / 61 In an 11 / 35 air conditioner, the fan assembly 112 continuously supplies air to the heat exchange cavity 106, and thus the pressure in the heat exchange cavity 106 is greater than the pressure in the electrical control box 108. In this case, the airflow in the fan cavity 104 flows continuously into the electrical control box 108 through the first heat dissipation hole 120. From there, the airflow in the electrical control box 108 at least partially flows continuously back to the fan cavity 104 through the second heat dissipation hole 124 to participate again in the air supply. The airflow flowing back to the fan cavity 104 through the second heat dissipation hole 124 can remove heat from the electrical control box 108, which in turn achieves effective heat dissipation of the electrical control box 108 and the electrical control 110 in the electrical control box 108.
[0046] Furthermore, the air conditioner according to the second embodiment has all the advantageous effects of the air conditioner described in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation to efficiently dissipate heat from the electrical control box 108 and the electrical control 110.
[0047] According to a third embodiment of the present invention, an air conditioner is provided.
[0048] Furthermore, based on the first embodiment, the air conditioner additionally includes a heat dissipation air duct 114, as illustrated in Figure 2. The heat exchange cavity 106 is in communication with the electrical control box 108 through the heat dissipation air duct 114. That is, during the operation of the fan assembly, the air in the heat exchange cavity 106 can be directed to the heat dissipation air duct 114 with the pressure difference and flow to the electrical control box 108 through the heat dissipation air duct 114. Petition 870230097790, dated 06 / 11 / 2023, page 29 / 61 12 / 35 performing efficient heat dissipation of the electrical control box 108 and the electrical control box 108.
[0049] In a further embodiment, due to the aforementioned heat dissipation air duct 114, the communication between the heat exchange cavity 106 and the electrical control box 108 can be greatly improved, and the volume of air flowing to the electrical control box 108 per unit of time can be guaranteed during the operation of the air conditioner, ensuring the heat dissipation effect in the electrical control box 108 and in the electrical control 110 in the electrical control box 108.
[0050] Furthermore, due to the aforementioned heat dissipation air duct 114, a requirement for a relative position between the heat exchange cavity 106 and the electrical control box 108 is lower, allowing for a more flexible mounting of the electrical control box 108. Mounting the electrical control box 108 is feasible provided that the electrical control box 108 can be arranged in a connection between the electrical control box 108 and the heat dissipation air duct 114.
[0051] Furthermore, an inlet end of the heat dissipation air duct 114 is located at a connection between the fan cavity 104 and the heat exchange cavity 106, to ensure that the inlet end of the heat dissipation air duct 114 is at a distance from a heat exchanger 144 in the heat exchange cavity 106. As a result, it is possible to ensure low humidity of the air flowing to the electrical control box 108. Thus, a buildup of humidity in the electrical control box 108 can be avoided to ensure dry air in the electrical control box 108. Therefore, the service life of each of the electrical control boxes 108 and the electrical control 110 can be guaranteed.
[0052] In addition, in this embodiment, as illustrated in Figure 1 and Figure 2, the air conditioner further includes a mounting beam 116 and a support member 118. The mounting beam 116 is Petition 870230097790, dated 06 / 11 / 2023, pp. 30 / 61 13 / 35 is arranged in a central part of the housing 102 and is located at a connection between the fan cavity 104 and the heat exchange cavity 106. The mounting beam 116 can be used as a crossbeam. The support member 118 is arranged in the heat exchange housing 106, and can rest against the inside of the housing 102 to ensure the resistance and hardness of the housing 102 itself, preventing dents in the housing 102 due to shock during transport and use of the air conditioner.
[0053] In an additional embodiment, as illustrated in Figure 2, it is possible to ensure that there is a predetermined space between the mounting beam 116 and the support member 118. The space between the mounting beam 116 and the support member 118 can be directly formed as the heat dissipation air duct 114. In this way, on the one hand, the inlet end of the heat dissipation air duct 114 can be ensured to be in communication with the connection between the fan cavity 104 and the heat exchange cavity 106. On the other hand, it is possible to omit an additional design of the structure of the heat dissipation air duct 114 to significantly simplify the structure of the heat dissipation air duct 114 and the entire air conditioner, while decreasing the weight of the air conditioner.
[0054] Therefore, in this embodiment, the relative position between the mounting beam 116 and the support member 118 is appropriately designed. In this way, the heat dissipation air duct 114 can be formed directly through the space between the mounting beam 116 and the support member 118, which is conducive to simplifying the structure of the air conditioner while facilitating the design, manufacture and assembly of the heat exchanger 144. Additionally, it is possible to contribute to the cost reduction of the heat exchanger 144. Furthermore, the mounting beam 116 has a communication opening configured to be in communication with the heat dissipation air duct 114 and the heat exchange cavity 106. Petition 870230097790, dated 06 / 11 / 2023, page 31 / 61 14 / 35
[0055] In an additional embodiment, support member 118 can be produced from support foam to further reduce the weight of the air conditioner.
[0056] Furthermore, the mounting beam 116 has a communication opening configured to communicate with the heat dissipation air duct 114 and the heat exchange cavity 106. In a further embodiment, as illustrated in Figure 4, the mounting beam 116 can be provided with a plurality of flanges to allow communication openings to be formed in the flanges. Furthermore, one or more communication openings can be formed and are designed based on the air volume required for actual heat dissipation of the electrical control box 108. Additionally, the shape of the communication opening can be designed as desired, being circular, oval, triangular, rectangular, or other irregular shapes. Furthermore, the aforementioned contents are understandable by persons skilled in the art.
[0057] Furthermore, the air conditioner according to the embodiment has all the advantageous effects of the air conditioner according to the first embodiment 1, and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation, efficiently dissipating heat from the electrical control box 108 and the electrical control 110.
[0058] According to a fourth embodiment of the present invention, an air conditioner is provided.
[0059] Additionally, based on the third embodiment, as illustrated in Figure 1 and Figure 2, in the air supply direction of the air conditioner, the electrical control box 108 is located on a lateral side of the fan cavity 104, and the heat dissipation air duct 114 is arranged transversely with respect to the direction of Petition 870230097790, dated 06 / 11 / 2023, pp. 32 / 61 15 / 35 air supply of the fan assembly 112. Thus, in this embodiment, by reasonably arranging the relative positions of the electrical control box 108 and the fan cavity 104, it is possible to ensure that the electrical control box 108 does not exert any influence on the air supply of the fan assembly 112 in the fan cavity 104, while ensuring that no interference occurs between the electrical control box 108 and the fan cavity 104.
[0060] Furthermore, the heat dissipation air duct 114 is arranged transversely to the direction of the air supply from the fan assembly 112 and extends towards the electrical control box 108. As a result, it is possible to ensure that the airflow in the heat exchange cavity 106 can enter the electrical control box 108 to dissipate heat from the electrical control box 108 and from the electrical control 110 in the electrical control box 108.
[0061] In this solution of the technique, a gap is formed between the inlet end of the heat dissipation air duct 114 and the outlet end of the fan cavity 104, to ensure a temporary storage space between the inlet end of the heat dissipation air duct 114 and the outlet end of the fan cavity 104. Furthermore, in this embodiment, a support member structure 118 is optimized to allow the mounting beam 116 to have an arc-shaped conductor surface 122 located at the inlet end of the heat dissipation duct 114.
[0062] In an additional embodiment, as illustrated in Figure 1 and Figure 2, due to the arc-shaped surface of the conductor 122, it is possible to prevent the support member 118 from forming a point at the inlet end of the heat dissipation air duct 114 and to reduce the air resistance of the support member 118 at the inlet end of the heat dissipation air duct 114, providing a good effect of Petition 870230097790, dated 06 / 11 / 2023, pp. 33 / 61 16 / 35 conduction at the inlet end of the heat dissipation air duct 114 by the surface of the arc-shaped conductor 122. That is, during the operation of the air conditioner, the air in the heat exchange cavity 106 is in contact with the surface of the arc-shaped conductor 122 at the inlet end of the heat dissipation air duct 114, and flows smoothly into the heat dissipation air duct under the conduction of the surface of the arc-shaped conductor 122. Therefore, the volume of air entering the heat dissipation duct 114 per unit time can be increased to improve the heat dissipation effect in the electrical control box 108. Therefore, efficient heat dissipation of the electrical control box 108 and the electrical control 110 can be achieved.
[0063] Furthermore, the air conditioner according to this embodiment has all the advantageous effects of the air conditioner described in the first embodiment and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation, efficiently dissipating heat from the electrical control box 108 and the electrical control 110.
[0064] According to a fifth embodiment of the present invention, an air conditioner is provided.
[0065] In addition, based on the first embodiment, the air conditioner additionally includes a heat exchanger 144. The heat exchanger 144 is disposed in the fan cavity 104 and may be in contact with the airflow in the heat exchange cavity 106 to exchange heat with the airflow during the operation of the air conditioner, realizing a cooling and a heating capacity of the air conditioner.
[0066] In a further embodiment, as illustrated in Figure 1 and Figure 2, a connection between the electrical control box 108 and the fan cavity 104 is located on one side of the heat exchanger 144 facing Petition 870230097790, dated 06 / 11 / 2023, pages 34 / 61 17 / 35 for the fan cavity 104. This means that the inlet end of the heat dissipation air duct 114 is guaranteed to be located on the side of the heat exchanger 144 facing the fan cavity 104. During the operation of the air conditioner, since the air located on the side of the heat exchanger 144 facing the fan cavity 104 has not yet come into contact with the heat exchanger 144 to exchange heat with the heat exchanger 144, this air has a low water vapor content. Therefore, when this air flows to the electrical control box 108, it is possible to prevent the accumulation of moisture in the electrical control box 108 to ensure that the air in the electrical control box 108 is dry, which, in turn, ensures the service life of each of the electrical control boxes 108 and the electrical control 110.
[0067] In an exemplary embodiment, as illustrated in Figure 1 and Figure 2, the heat exchanger 144 is arranged obliquely in the heat exchanger 144. Furthermore, it is ensured that the side of the heat exchanger 144 facing the fan cavity 104 is positioned at a higher level. In this way, it is possible to ensure a sufficient distance between the inlet end of the heat dissipation air duct 114 and the heat exchanger 144. That is, sufficient distance is ensured between the inlet end of the heat dissipation air duct 114 and the heat exchanger 144, which can ensure low humidity of the air flowing to the electrical control box 108. Therefore, it is possible to ensure that the electrical control box 108 and the electrical control 110 are free from damage, such as corrosion due to humidification.
[0068] In addition, in this embodiment, the housing 102 additionally has a pipe cavity 152. A final portion of a heat exchanger cooling pipe is located in the pipe cavity 152 and may be in communication with an external pipe in a cooling cavity to ensure the intake and exhaust of a refrigerant. Petition 870230097790, dated 06 / 11 / 2023, pp. 35 / 61 18 / 35 Furthermore, the pipe cavity 152 is isolated from the heat exchange cavity 106 by the support member 118. The sealing of the pipe cavity 152 is ensured by the support member 118. The heat dissipation air duct 114 is located between the pipe cavity 152 and the electrical control box 108. Thus, by isolating the pipe cavity 152 from the heat exchange cavity 106 by the support member 118, it is possible to ensure the sealing of the pipe cavity 152, which in turn prevents the generation of condensation in the pipe cavity 152. Additionally, since the heat dissipation air duct 114 is located between the pipe cavity 152 and the electrical control box 108, it is possible to ensure that the heat dissipation air duct 114 is isolated from the pipe cavity 152 by the support member 118, while the airflow in the heat dissipation air duct 114 can be prevented from entering the pipe cavity 152.As a result, the generation of condensation in the cavity of pipe 152 can be avoided.
[0069] Furthermore, the air conditioner according to the embodiment has all the advantageous effects of the air conditioner described in the first embodiment and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation, efficiently dissipating heat from the electrical control box 108 and the electrical control 110.
[0070] According to a sixth embodiment of the present invention, an air conditioner is provided.
[0071] In addition, based on the first embodiment, the air conditioner further includes an air duct hood 126, as illustrated in Figure 1 and Figure 2. The air duct hood 126 is disposed in the fan cavity 104 and can provide good air direction during the operation of the fan assembly 112, to direct an airflow generated by the fan assembly 112 to the Petition 870230097790, dated 06 / 11 / 2023, pp. 36 / 61 19 / 35 heat exchange cavity 106.
[0072] Additionally, in the embodiment as illustrated in Figure 2, the air duct hood 126 has an air supply outlet 128. The air supply outlet 128 is designed to face the heat exchange cavity 106. Furthermore, a side wall 130 of the air duct hood 126 has an inclined duct surface 132 located at the air supply outlet 128. As a result, the air supply outlet 128 has an enlarged shape. In addition, the inclined duct surface 132 extends towards the connection between the heat exchange cavity 106 and the electrical control box 108.
[0073] Thus, during the operation of the air conditioner, as illustrated in Figure 2, the airflow generated by the fan assembly 112 can be diffused as it flows from the air supply outlet 128, allowing the airflow to flow at least partially towards the connection between the heat exchange cavity 106 and the electrical control box 108. This means that it is possible to allow the airflow to flow at least partially towards the inlet end of the heat dissipation air duct 114, which is conducive to increasing the volume of air flowing to the electrical control box 108 per unit time, which in turn improves the heat dissipation effect in the electrical control box 108.
[0074] It should be especially noted that the operation of the fan assembly 112 can supply air to the heat exchange cavity 106. An accumulation of air in the heat exchange cavity 106 will result in a high pressure in the heat exchange cavity 106. In this case, the air in the heat exchange cavity 106 can flow to the electrical control box 108. In this embodiment, by arranging the inclined surface of the conductor 132 based on this, the airflow supplied by the fan assembly 112 can flow directly towards the connection between the heat exchange cavity 106 and the electrical control box 108, which further improves the effect of Petition 870230097790, dated 06 / 11 / 2023, pp. 37 / 61 20 / 35 thermal dissipation in the electrical control box 108.
[0075] Furthermore, in this embodiment, as illustrated in Figure 2, the air duct hood 126 has an air inlet 134. The air inlet 134 and the air supply outlet 128 are opposite each other. The air inlet 134 is arranged towards an air return inlet 136 of the housing 102, and can be configured to draw air from an external environment. Additionally, the electrical control box 108 is arranged on a lateral side of the air duct hood 126. The heat dissipation air duct 114 is arranged transversely. In this way, the airflow generated by the fan assembly 112 can be at least partially directed directly to the connection between the heat exchange cavity 106 and the electrical control box 108.
[0076] Furthermore, the air conditioner according to the embodiment has all the advantageous effects of the air conditioner described in the first embodiment and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation, efficiently dissipating heat from the electrical control box 108 and the electrical control 110.
[0077] According to a seventh embodiment of the present invention, an air conditioner is provided.
[0078] Additionally, based on the first embodiment, the fan cavity 104 has a return air inlet 136, and the heat exchange cavity 106 has an air outlet 138, as illustrated in Figure 1 and Figure 2. The air passages (not shown) of the air conditioner are located between the return air inlet 136 and the air outlet 138. During the operation of the air conditioner, outside air can flow into the air passages through the return air inlet 136. The airflow is driven by the fan assembly 112 into the heat exchange compartment 106 and is discharged through the air outlet 138. In one embodiment Petition 870230097790, dated 06 / 11 / 2023, pp. 38 / 61 21 / 35 additionally, the electrical control box 108 is placed on one side of the air passages. Furthermore, the electrical control box 108 is in communication with some of the air passages located in the heat exchange cavity 106. In this way, it is possible to ensure that the air in the air passages can be moved by the pressure difference to flow into the electrical control box 108, thus cooling the electrical control box 108.
[0079] Furthermore, in this embodiment, as illustrated in Figure 1 and Figure 2, the fan assembly 112 includes a fan impeller 140 and an actuator 142 connected to each other. The fan impeller 140 and the fan assembly 112 are both positioned in the fan cavity 104. Additionally, it is ensured that the fan impeller 140 is disposed in the air duct and the actuator 142 is disposed between the fan impeller 140 and the electrical control box 108. Thus, during an operation of the fan assembly 112, the actuator 142 drives the fan impeller 140 to rotate in the air duct, to allow the fan impeller 140 to supply air to the heat exchange cavity 106.In this case, the pressure in the heat exchange cavity 106 is higher, while the pressure in the electrical control box 108 is lower, which in turn allows the airflow in the heat exchange cavity 106 to be driven by the pressure difference to flow into the electrical control box 108, thus achieving efficient heat dissipation from the electrical control box 108.
[0080] In some embodiments, the actuator 142 is a motor, and the electrical control box 108 includes a motor drive module. The motor drive module is electrically connected to the motor and is configured to control the motor's operation.
[0081] Furthermore, in a case where the electrical control box 108 is in communication with the fan cavity 104, the electrical control box 108 is in communication with a position where the Petition 870230097790, dated 06 / 11 / 2023, pages 39 / 61 22 / 35 actuator 142 is located and is in communication with the exterior of the air passages (since some of the air passages are located in the hood of the air duct 126). In this case, the pressure at a position where actuator 142 is located is low, which in turn ensures that air in the electrical control box 108 can flow into the fan cavity 104.
[0082] Furthermore, the air conditioner according to the embodiment has all the advantageous effects of the air conditioner described in the first embodiment and can ensure that the airflow in the heat exchange cavity 106 flows continuously into the electrical control box 108 during operation, efficiently dissipating heat from the electrical control box 108 and the electrical control 110.
[0083] According to an eighth embodiment of this invention, an air conditioner is provided.
[0084] In addition, based on the first embodiment, the air conditioner additionally includes a filter 146, as illustrated in Figure 2. The filter 146 is located in the air return inlet 136 of the fan cavity 104 and is connected to the housing 102. In this way, during the operation of the air conditioner, the filter 146 can provide good filtration against foreign materials mixed in the air, which, in turn, ensures the cleanliness of the air flowing to the housing 102 and additionally ensures the cleanliness of the air flowing to the electrical control box 108.
[0085] In a further embodiment, the electrical control 110 in the electrical control box 108 is generally a precision element with a high price.In this embodiment, in the case where the heat from the electrical control box 108 and the electrical control 110 is dissipated by means of the air in the heat exchange cavity 106, by placing the filter 146 in the return air inlet 136 of the air conditioner, it is possible to effectively reduce or prevent dust from entering the electrical control box 108, which can ensure the cleanliness of the electrical control box 108 and the service life of the electrical control 110. Petition 870230097790, dated 06 / 11 / 2023, pp. 40 / 61 23 / 35
[0086] In an additional embodiment, filter 146 may be a mesh filter. Furthermore, filter 146 is removablely mounted on the return air inlet 136 to facilitate replacement, maintenance and cleaning by the user.
[0087] In any of the above embodiments, in the case where the electrical control box 108 is in communication with the heat exchange cavity 106, the electrical control box 108 may also be in communication with the fan cavity 104 or with the external environment, or with both, the fan cavity 104 and the external environment. Additionally, the description of the communications of the electrical control box 108 will be provided below, respectively.
[0088] In a communication, as illustrated in Figure 5, the electrical control box 108 is in communication with the fan cavity 104 and the heat exchange cavity 106. In this way, the fan assembly 112 can supply air to the heat exchange cavity 106 during its operation, which increases the pressure in the heat exchange cavity 106 to be higher than the pressure in the electrical control box 108 and the pressure in the fan cavity 104. In this case, with the activation of the pressure difference, the air in the heat exchange cavity 106 flows into the electrical control box 108, and then the air in the electrical control box 108 can flow into the fan cavity 104, forming a heat dissipation flow path. In this way, the airflow flowing into the electrical control box 108 can effectively dissipate heat from the electrical control box 108 and the electrical control 110 inside the electrical control box 108.Furthermore, when air in the electrical control box 108 flows into the fan cavity 104, the air can also carry heat from the electrical control box 108 to the fan cavity 104, which will further dissipate heat from the electrical control box 108. Therefore, the heat dissipation effect in the electrical control box 108 can be significantly improved. Petition 870230097790, dated 06 / 11 / 2023, pages 41 / 61 24 / 35
[0089] Furthermore, as illustrated in Figure 5, in the case where the electrical control box 108 is in communication with the fan cavity 104 and the heat exchange cavity 106, the electrical control box 108 has a first heat dissipation hole 120 and a second heat dissipation hole 124. The electrical control box 108 is in communication with the heat exchange cavity 106 through the first heat dissipation hole 120. Additionally, the electrical control box 108 is in communication with the fan cavity 104 through the second heat dissipation hole 124. Furthermore, the air flowing to the fan cavity 104 can be blown towards the heat exchange cavity 106 again. This air can be blown after a heat exchange, or it can further cool the electrical control box 108.
[0090] In another communication, the electrical control box 108 is in communication with the heat exchange cavity 106 and the external environment. In this way, the fan assembly 112 can supply air to the heat exchange cavity 106 during its operation, which increases the pressure in the heat exchange cavity 106 to be greater than the pressure in the electrical control box 108 and the pressure in the external environment. In this case, with the activation of the pressure difference, the air in the heat exchange cavity 106 flows into the electrical control box 108, and then the air in the electrical control box 108 can flow to the external environment, forming an airflow path. In this way, the airflow flowing into the electrical control box 108 can effectively dissipate heat from the electrical control box 108 and the electrical control 110 inside the electrical control box 108.Furthermore, when air flows from the electrical control box 108 to the outside environment, it can also carry heat away from the electrical control box 108, further improving its heat dissipation. Therefore, the heat dissipation effect on the electrical control box 108 can be significant. Petition 870230097790, dated 06 / 11 / 2023, pages 42 / 61 25 / 35 improved.
[0091] Furthermore, in the case where the electrical control box 108 is in communication with the heat exchange cavity 106 and the external environment, the electrical control box 108 has a first heat dissipation hole 120 and a third heat dissipation hole. The electrical control box 108 is in communication with the heat exchange cavity 106 through the first heat dissipation hole 120. In addition, the electrical control box 108 is in communication with the external environment through the third heat dissipation hole. Furthermore, this air no longer participates in the heat dissipation of the electrical control box 108.
[0092] In another additional communication, the electrical control box 108 is in communication with the heat exchange cavity 106, the fan cavity 104, and the external environment. In this way, the fan assembly 112 can supply air to the heat exchange cavity 106 during its operation, which increases the pressure in the heat exchange cavity 106 to be greater than the combined pressure in the electrical control box 108, the pressure in the fan cavity 104, and the pressure in the external environment. In this case, with the activation of the pressure difference, the air in the heat exchange cavity 106 flows into the electrical control box 108, and then the air in the electrical control box 108 can flow into the fan cavity 104 and to the external environment, forming two branches.In this way, the airflow flowing into the electrical control box 108 can effectively dissipate heat from the electrical control box 108 and the electrical control 110 inside the electrical control box 108. Furthermore, when air in the electrical control box 108 flows into the fan cavity 104 and the external environment, the air can also carry heat from the electrical control box 108 to the external environment, further dissipating heat from the electrical control box 108. Therefore, the thermal dissipation effect in the electrical control box 108 can be significantly improved. Petition 870230097790, dated 06 / 11 / 2023, pp. 43 / 61 26 / 35
[0093] Furthermore, the electrical control box 108 has the first heat dissipation hole 120, the second heat dissipation hole 124, and the third heat dissipation hole. The electrical control box 108 is in communication with the heat exchange cavity 106 through the first heat dissipation hole 120. Additionally, the electrical control box 108 is in communication with the fan cavity 104 through the second heat dissipation hole 124. Additionally, the electrical control box 108 is in communication with the external environment through the third heat dissipation hole. Furthermore, this air no longer participates in the heat dissipation of the electrical control box 108. Furthermore, the air flowing to the fan cavity 104 can be blown towards the heat exchange cavity 106 again. This air can be blown after a heat exchange, or it can further cool the electrical control box 108.Some of the air flowing to the outside environment no longer participates in the heat dissipation of the electrical control box 108.
[0094] In an exemplary embodiment, when the electrical control box 108 is in communication with the fan cavity 104, since the fan assembly 112 is disposed in the fan cavity 104, the fan assembly 112 can additionally decrease the pressure in the fan cavity 104 during its operation. In this way, the pressure in the fan cavity 104 increases the pressure in the electrical control box 108, which additionally drives the circulation of air in the electrical control box 108 to the fan cavity 104, further improving the heat dissipation efficiency of the electrical control box 108.
[0095] In an exemplary embodiment, as illustrated in Figure 5, the electrical control box 108 may be provided with a plurality of flanges, and the first heat dissipation hole 120 is formed in the flanges. Furthermore, one or more of the first heat dissipation holes 120 may Petition 870230097790, dated 06 / 11 / 2023, pages 44 / 61 27 / 35 can be formed and can be designed based on the volume of air required for the actual heat dissipation of the electrical control box 108. More heat dissipation holes 120 can be designed when a larger volume of air is needed to dissipate heat from the electrical control box 108. Furthermore, the shape of the first heat dissipation hole 120 can be designed as desired. The first heat dissipation hole 120 can be circular, oval, triangular, rectangular, or other irregular shapes. Additionally, the aforementioned revelations are understandable to persons skilled in the art.
[0096] In an exemplary embodiment, the electrical control box 108 may be provided with a plurality of flanges, and the second heat dissipation hole 124 is formed in the flanges.

More third heat dissipation holes may be designed when a larger volume of air is required for Petition 870230097790, dated 06 / 11 / 2023, pp. 45 / 61 28 / 35 dissipate the heat from the electrical control box 108. Furthermore, the shape of the third heat dissipation hole can be designed as desired. The third heat dissipation hole can be circular, oval, triangular, rectangular, or other irregular shapes. Additionally, the aforementioned disclosures are understandable by persons skilled in the art.
[0098] In any of the above embodiments, the electrical control 110 includes the motor drive module and is configured to drive an air conditioner motor to operate. In an exemplary embodiment, the motor drive module generates heat during the motor drive operation. If the motor drive module is designed together with the motor, the costs of the entire motor will be high. Therefore, in the present invention, the motor drive module is disposed in the electrical control box 108 and the heat is dissipated through the airflow in the heat exchange cavity 106.In this way, the heat dissipation requirements of each of the motor drive modules and the 108 electrical control box can be met, while reducing the costs of the motor and the air conditioner.
[0099] In either of the above embodiments, as illustrated in Figure 3, the electrical control box 108 includes a box body 148 and a cover body 150. The box body 148 and the housing 102 may be integrally formed. The cover body 150 is arranged so as to cover the box body 148.
[00100] According to a first embodiment of the present invention, an air conditioner is provided. The air conditioner includes a housing 102, an electrical control box 108, an electrical control 110, and a fan assembly 112. The fan assembly 112 is configured to supply air to the heat exchange cavity 106 during its operation, which increases the pressure in the heat exchange cavity 106 to be greater than the pressure in the electrical control box 108. Therefore, during the Petition 870230097790, dated 06 / 11 / 2023, pp. 46 / 61 29 / 35 operation of the air conditioner, due to a pressure difference between the heat exchange cavity 106 and the electrical control box 108, an airflow in the heat exchange cavity 106 flows at least partially to the electrical control box 108 and returns to the fan cavity 104 after flowing through the electrical control box 108. The airflow passing through the electrical control box 108 can effectively dissipate heat from the electrical control box 108 and the electrical control 110 into the electrical control box 108, therefore, it is possible to ensure an adequate temperature in the electrical control box 108 and a temperature reduction of the electrical control 110, to ensure the safe use of the electrical control box 108 and the electrical control 110.
[00101] Furthermore, in this embodiment, the electrical control box 108 has a first heat dissipation hole 120 and a second heat dissipation hole 124. The first heat dissipation hole 120 is in communication with the heat exchange cavity 106, which ensures that the airflow in the heat exchange cavity 106 can flow to the electrical control box 108. The second heat dissipation hole 124 is in communication with the fan cavity 104, which ensures that the airflow in the electrical control box 108 can flow to the fan cavity 104.
[00102] In addition, in the embodiments, the air conditioner further includes a heat dissipation air duct 114. The heat exchange cavity 106 is in communication with the electrical control box 108 through the heat dissipation air duct 114. In a further embodiment, one end of the inlet of the heat dissipation air duct 114 is located at a connection between the fan cavity 104 and the heat exchange cavity 106. In this way, it is possible to ensure that the inlet end of the heat dissipation air duct 114 is at a distance from the heat exchanger 144 in the heat exchange compartment 106. In addition, the air conditioner further includes a beam of Petition 870230097790, dated 06 / 11 / 2023, pp. 47 / 61 30 / 35 mounting 116 and a support member 118. There is a predetermined spacing between the mounting beam 116 and the support member 118. The space between the mounting beam 116 and the support member 118 is directly formed as the heat dissipation air duct 114. Furthermore, in the air supply direction of the air conditioner, the electrical control box 108 is located on a lateral side of the fan cavity 104. The heat dissipation air duct 114 is arranged transversely to the air supply direction of the fan mounting 112. Additionally, a gap is formed between the inlet end of the heat dissipation air duct 114 and the outlet end of the fan cavity 104. The mounting beam 116 has an arc-shaped conductor surface 122 located at the inlet end of the heat dissipation air duct 114.
[00103] In addition, in this embodiment, the air conditioner additionally includes a heat exchanger 144. The heat exchanger 144 is positioned in the fan cavity 104. The connection between the electrical control box 108 and the fan cavity 104 is located on one side of the heat exchanger 144 facing the fan cavity 104. During the operation of the air conditioner, the air located on the side of the heat exchanger 144 facing the fan cavity 104 has not yet come into contact with the heat exchanger 144 to exchange heat with the heat exchanger 144. When this airflow flows into the electrical control box 108, it is possible to prevent the accumulation of moisture in the electrical control box 108 to ensure that the air in the electrical control box 108 is dry, which, in turn, ensures the service life of each of the electrical control boxes 108 and the electrical control 110.In addition, housing 102 has an additional piping cavity 152. A final portion of a heat exchanger refrigerant pipe is located in the piping cavity 152 and may be in communication with an external pipe. Petition 870230097790, dated 06 / 11 / 2023, pp. 48 / 61 31 / 35 refrigerant cavity to ensure refrigerant intake and exhaust. Furthermore, the pipe cavity 152 is isolated from the heat exchange cavity 106 by the support member 118.
[00104] Additionally, in this embodiment, the air conditioner also includes an air duct hood 126. The air duct hood 126 has an air supply outlet 128. A side wall 130 of the air duct hood 126 has an inclined duct surface 132 located at the air supply outlet 128. As a result, the air supply outlet 128 has an enlarged shape. Furthermore, the air duct hood 126 has an air inlet 134. The air inlet 134 and the air supply outlet 128 are opposite each other. The air inlet 134 faces the air return inlet 136 of the housing 102. The electrical control box 108 is positioned on a side of the air duct hood 126. The heat dissipation air duct 114 is arranged transversely. In addition, the fan cavity 104 has an air return inlet 136, and the heat exchange cavity 106 has an air outlet 138.The air passages of the air conditioner are located between the return air inlet 136 and the air outlet 138. The electrical control box 108 is arranged on one side of the air passages. Furthermore, the fan assembly 112 includes a fan impeller 140 and an actuator 142 connected to each other.
[00105] Additionally, in this embodiment, the air conditioner also includes a filter 146. The filter 146 is located in the air return inlet 136 of the fan cavity 104 and is connected to the housing 102. The filter 146 can provide good filtration for foreign material mixed in the air, which ensures the cleanliness of the air flowing into the housing 102 and, additionally, ensures the cleanliness of the air flowing into the electrical control box 108.
[00106] In an exemplary embodiment, electrical controls, Petition 870230097790, dated 06 / 11 / 2023, pp. 49 / 61 32 / 35, such as the motor drive module, will generate heat during use. In the related technique, heat dissipation members, such as an aluminum member, are arranged in the electrical control box. However, the heat dissipation efficiency is low, which does not effectively solve the heat dissipation demand of each of the electrical control units and the electrical control box, easily resulting in damage to the electrical controls. The air conditioner, according to the embodiments of this invention, can effectively solve the heat dissipation demand of the electrical control 110, such as the motor drive module, and can provide protection against dust and humidity inside the electrical control box 108.
[00107] With the air conditioner according to the embodiments of the present invention, as illustrated in Figure 1, Figure 2 and Figure 3, the heat dissipation air duct 114 is formed between the support member 118 and the mounting beam 116. The heat dissipation duct 114 is configured to connect the heat exchange cavity 106 and the electrical control box 108. During the operation of the air conditioner, since the fan assembly 112 continuously supplies air to the heat exchange cavity 106, the air pressure in the heat exchange cavity 106 is relatively high, while the air pressure in each fan cavity 104, where the fan assembly 112 is located, the interior of the electrical control box 108 and the external environment is relatively low. Therefore, the air in the heat exchange cavity 106 will flow into the fan cavity 104 to improve the heat dissipation of the electrical control box 108 and the electrical control 110.
[00108] Furthermore, as illustrated in Figure 5, the first heat dissipation hole 120 can be formed on one side of the electrical control box 108 facing the heat exchange cavity 106 to ensure that the airflow in the heat exchange cavity 106 flows into the box. Petition 870230097790, dated 06 / 11 / 2023, pages 50 / 61 33 / 35 electrical control 108 through the first heat dissipation hole 120. The second heat dissipation hole 124 can be formed on one side of the electrical control box 108 facing the fan cavity 104, to ensure that the airflow in the electrical control box 108 returns to the fan cavity 104 through the second heat dissipation hole 124 and removes the heat in the electrical control box 108. In this way, the heat dissipation effect in the electrical control box 108 and the electrical control 110 can be further enhanced.
[00109] In addition, a third heat dissipation hole can be additionally formed in the electrical control box 108 to ensure that the airflow in the electrical control box 108 flows to the external environment through the third heat dissipation hole. In this case, the air in the electrical control box 108 can additionally flow to the external environment and remove the heat in the electrical control box 108. Therefore, the heat dissipation effect in the electrical control box 108 and the electrical control 110 can be further enhanced.
[00110] Furthermore, as illustrated in Figure 2, filter 146 is located at the air return inlet 136 of the fan cavity 104. In this way, the air flowing into the air conditioner has a low content of foreign materials, which ensures the cleanliness of the air flowing into the housing 102 and, additionally, ensures the cleanliness of the air flowing into the electrical control box 108.
[00111] Furthermore, as illustrated in Figure 1 and Figure 2, the heat exchanger 144 is located in the fan cavity 104. Additionally, the inlet end of the heat dissipation air duct 114 is located on the side of the heat exchanger 144 facing the fan cavity 104. Therefore, the air flowing in the heat dissipation duct 114 and the electrical control box 108 do not exchange heat with the heat exchanger 144. Consequently, the water vapor content in this air is low, which may Petition 870230097790, dated 06 / 11 / 2023, pages 51 / 61 34 / 35 prevent the accumulation of moisture in the electrical control box 108. As a result, it is possible to ensure that the air in the electrical control box 108 is dry, further guaranteeing the service life of each of the electrical control boxes 108 and the electrical control 110.
