Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] Electric components such as motor drive modules generate heat during use. In the related art, a heat sink is set in the electric control box, but the heat dissipation efficiency of the heat sink is not high and it cannot effectively solve the heat dissipation problem of the electric components and the electric control box, which makes the electric components very easy to be damaged. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, the present invention provides an air conditioner.

[0005] The present invention provides an air conditioner, comprising: a shell, the shell comprising a fan cavity and a heat exchange cavity connected to each other; an electric control box, arranged in the shell and connected to the heat exchange cavity and the fan cavity; an electric control component, arranged in the electric control box; a fan assembly, arranged in the fan cavity, and the fan assembly can be used to supply air to the heat exchange cavity and dissipate heat for the electric control box.

[0006] The air conditioner proposed by the present invention comprises a housing, an electric control box, an electric control unit and a fan assembly. Along the air supply direction of the air conditioner, the housing comprises a fan cavity and a heat exchanger that are connected; the electric control box is arranged in the housing and is connected to the heat exchange cavity and the fan cavity. The electric control unit is arranged in the electric control and the electric control box and can ensure the control operation of the entire air conditioner. The fan assembly is arranged in the fan cavity and can supply air to the heat exchange cavity during operation.

[0007] In particular, the fan assembly can supply air to the heat exchange cavity during operation, which increases the pressure in the heat exchange cavity and makes it higher than the pressure in the electric control box and the fan cavity. Therefore, during the operation of the air conditioner, due to a certain pressure difference between the heat exchange cavity and the electric control box, at least part of the gas in the heat exchange cavity enters the electric control box and returns to the fan cavity after passing through the electric control box. During the use of the air conditioner, the electric control components will generate heat, and the temperature inside the electric control box will rise. High temperature will easily cause damage to the electric control components and affect the service life of the electric control components. Therefore, the airflow flowing through the electric control box can effectively dissipate the heat of the electric control box and the electric control components in the electric control box, thereby ensuring that the temperature in the electric control box is appropriate, and ensuring that the temperature of the electric control components is reduced, ensuring the safety of the use of the electric control box and the electric control components.

[0008] Furthermore, during the operation of the air conditioner proposed by the present invention, the gas in the heat exchange chamber enters the electric control box, and the fan assembly can continuously supply air to the heat exchange chamber during operation, which makes the pressure in the heat exchange chamber greater than the pressure in the electric control box and the fan chamber. Therefore, the present invention can significantly increase the amount of gas entering the electric control box to improve the heat dissipation effect of the electric control box and the electric components inside the electric control box, especially compared with the technical solution of using the air from the external environment to cool the electric control box in the related art, the heat dissipation effect of the present invention is more obvious. Moreover, the temperature of the airflow driven by the fan assembly is relatively low, which makes the airflow in the heat exchange chamber cool the electric components in the electric control box to a certain extent when it flows through the electric control box, further reducing the temperature of the electric components and ensuring the service life of the electric components.

[0009] Therefore, the present invention can form a circulating flow path inside the air conditioner, so that after the airflow in the fan cavity enters the heat exchange cavity, at least part of the airflow enters the electrical control box and returns to the fan cavity through the electrical control box, thereby achieving efficient heat dissipation of the electrical control box and ensuring the service life of the electrical control box and electrical components.

[0017] In some possible technical solutions, the shell further includes a pipeline cavity, and the pipeline cavity is isolated from the heat exchange cavity by a support member; and the heat dissipation duct is located between the pipeline cavity and the electric control box.

DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0035] Refer to the following Figures 1 to 5 The air conditioner provided according to some embodiments of the present invention is described. Figure 1 and Figure 2 The dashed arrows indicate the direction of airflow.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the first embodiment of the present invention provides an air conditioner, including: a housing 102 , an electric control box 108 , an electric control unit 110 and a fan assembly 112 .

[0037] Among them, Figure 1 and Figure 2 As shown, along the air supply direction of the air conditioner, the housing 102 includes a fan chamber 104 and a heat exchanger 144 that are connected; the electric control box 108 is arranged in the housing 102, and the electric control box 108 is connected to the heat exchange chamber 106. The electric control unit 110 is arranged in the electric control and the electric control box 108, and can ensure the control operation of the entire air conditioner. The fan assembly 112 is arranged in the fan chamber 104, and can supply air to the heat exchange chamber 106 during operation.

[0038] In particular, if Figure 1 and Figure 2 As shown, the fan assembly 112 can supply air to the heat exchange chamber 106 during operation, which increases the pressure in the heat exchange chamber 106 and makes it higher than the pressure in the electric control box 108. Therefore, during the operation of the air conditioner, due to a certain pressure difference between the heat exchange chamber 106 and the electric control box 108, at least part of the gas in the heat exchange chamber 106 enters the electric control box 108, and returns to the fan chamber 104 after passing through the electric control box 108.

[0039] During the use of the air conditioner, the electric control unit 110 generates heat, and the temperature inside the electric control box 108 increases. The high temperature may easily damage the electric control unit 110 and affect the service life of the electric control unit 110. Therefore, the airflow flowing through the electric control box 108 can effectively dissipate the heat of the electric control box 108 and the electric control unit 110 inside the electric control box 108, thereby ensuring that the temperature inside the electric control box 108 is appropriate, and the temperature of the electric control unit 110 is reduced, thereby ensuring the safety of the use of the electric control box 108 and the electric control unit 110.

[0040] Furthermore, during the operation of the air conditioner proposed in this embodiment, the gas in the heat exchange chamber 106 enters the electric control box 108, and the fan assembly 112 can continuously supply air to the heat exchange chamber 106 during operation, which makes the pressure in the heat exchange chamber 106 greater than the pressure of the electric control box 108 and the fan chamber 104. Therefore, this embodiment can significantly increase the amount of gas entering the electric control box 108, so as to improve the heat dissipation effect of the electric control box 108 and the electric components 110 inside the electric control box 108, especially compared with the technical solution of using the air of the external environment to cool the electric control box in the related art, the heat dissipation effect of the present invention is more obvious.

[0041] Moreover, the temperature of the airflow driven by the fan assembly 112 is relatively low, so that the airflow in the heat exchange chamber 106 cools down the electrical control component 110 in the electrical control box 108 to a certain extent when entering the electrical control box 108, further reducing the temperature of the electrical control component 110 and ensuring the service life of the electrical control component 110.

[0042] Therefore, the air conditioner proposed in this embodiment can form a circulating flow path inside the air conditioner, so that after the airflow in the fan cavity 104 enters the heat exchange cavity 106, at least part of the airflow enters the electrical control box 108, and returns to the fan cavity 104 through the electrical control box 108, and then the electrical control box 108 is connected to the heat exchange cavity 106 through this part of the airflow; during operation, the pressure in the heat exchange cavity 106 is higher than the pressure in the electrical control box 108 and the fan cavity 104, so that the airflow in the heat exchange cavity 106 continuously flows through the electrical control box 108, thereby realizing effective heat dissipation of the electrical control box 108 and the electrical control component 110.

[0043] The second embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0044] like Figure 4 and Figure 5 As shown, the electric control box 108 is provided with a first heat dissipation hole 120 and a second heat dissipation hole 124. The first heat dissipation hole 120 is connected to the heat exchange cavity 106 to ensure that the airflow in the heat exchange cavity 106 can enter the electric control box 108; the second heat dissipation hole 124 is connected to the fan cavity 104 to ensure that the airflow in the electric control box 108 can enter the fan cavity 104. In this way, a circulation flow path can be formed between the fan cavity 104, the heat exchange cavity 106 and the electric control cavity to continuously dissipate heat for the electric control box 108 and the electric components 110 in the electric control box 108 during the operation of the air conditioner.

[0045] Specifically, during the operation of the air conditioner, the fan assembly 112 continuously supplies air to the heat exchange chamber 106, and the pressure of the heat exchange chamber 106 is greater than the pressure in the electric control box 108; at this time, the airflow in the fan chamber 104 continuously enters the electric control box 108 through the first heat dissipation hole 120; then, at least part of the airflow in the electric control box 108 continuously flows back to the fan chamber 104 through the second heat dissipation hole 124 to participate in air supply again. Among them, the airflow flowing back to the fan chamber 104 from the second heat dissipation hole 124 can take away the heat in the electric control box 108, thereby achieving effective heat dissipation of the electric control box 108 and the electric components 110 inside the electric control box 108.

[0046] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0047] The third embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0048] like Figure 2 As shown, the air conditioner further includes a heat dissipation duct 114, and the heat exchange chamber 106 and the electric control box 108 are connected through the heat dissipation duct 114. That is, during the operation of the fan assembly, the air in the heat exchange chamber 106 can enter the heat dissipation duct 114 driven by the pressure difference, and enter the electric control box 108 through the heat dissipation duct 114, thereby achieving efficient heat dissipation of the electric control box 108 and the electric control box 108.

[0049] In particular, due to the use of the above-mentioned heat dissipation duct 114, the connectivity between the heat exchange chamber 106 and the electrical control box 108 can be greatly improved, and the amount of gas entering the electrical control box 108 per unit time during the operation of the air conditioner can be guaranteed, thereby ensuring the heat dissipation effect of the electrical control box 108 and the electrical components 110 in the electrical control box 108.

[0050] Furthermore, due to the use of the heat dissipation duct 114, the requirements for the relative position between the heat exchange chamber 106 and the electric control box 108 are reduced, making the installation of the electric control box 108 more flexible, as long as it can be set at a position where the heat dissipation duct 114 can be connected.

[0051] In addition, the inlet end of the heat dissipation duct 114 is located at the connecting point of the fan cavity 104 and the heat exchange cavity 106, ensuring that the inlet end of the heat dissipation duct 114 is at a certain distance from the heat exchanger 144 in the heat exchange cavity 106, ensuring that the humidity of the air entering the electric control box 108 is low, avoiding the accumulation of moisture inside the electric control box 108, ensuring that the air inside the electric control box 108 is relatively dry, and further ensuring the service life of the electric control box 108 and the electric control component 110.

[0052] In this embodiment, further, Figure 1 and Figure 2 As shown, the air conditioner further includes a mounting beam 116 and a support member 118. The mounting beam 116 is disposed in the middle of the housing 102 and is located at the connection between the fan chamber 104 and the heat exchange chamber 106. The mounting beam 116 can be used as a cross beam. The support member 118 is disposed in the heat exchange chamber 106 and can abut against the inside of the housing 102 to ensure the strength and hardness of the housing 102 itself and to prevent the housing 102 from being dented due to collision during transportation and use of the air conditioner.

[0053] In particular, if Figure 2 As shown, this embodiment ensures that there is a certain space between the mounting beam 116 and the support member 118, and directly forms the heat dissipation duct 114 through the space between the mounting beam 116 and the support member 118. In this way, on the one hand, it can ensure that the inlet end of the heat dissipation duct 114 is connected to the connection point between the fan cavity 104 and the heat exchange cavity 106, and on the other hand, it can avoid additional design of the heat dissipation duct 114, which can greatly simplify the structure of the heat dissipation duct 114 and the entire air conditioner, while reducing the weight of the air conditioner.

[0054] Therefore, the present embodiment cleverly designs the relative positions of the mounting beam 116 and the support member 118, and the heat dissipation duct 114 can be directly formed through the space between the mounting beam 116 and the support member 118, which is conducive to simplifying the structure of the air conditioner, and is convenient for the design, processing and assembly of the heat exchanger 144, and is also conducive to reducing the cost of the heat exchanger 144. In addition, the mounting beam 116 is provided with a communication port, and the communication port is connected to the heat dissipation duct 114 and the heat exchange chamber 106.

[0055] In a specific embodiment, the support member 118 may be made of support foam, thereby reducing the weight of the air conditioner.

[0056] In addition, the mounting beam 116 is provided with a communication port, and the communication port is connected to the heat dissipation duct 114 and the heat exchange chamber 106. In a specific embodiment, the mounting beam 116 may be provided with a plurality of folded edges so that the position of the folded edges forms the above-mentioned communication port. In addition, the number of the communication ports may be one or more, and is designed according to the air volume required for the actual heat dissipation of the electric control box 108. In addition, the shape of the communication port may be designed according to the actual situation, and may be circular, elliptical, triangular, rectangular or other irregular shapes. In addition, the above content is understandable to those skilled in the art.

[0057] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0058] The fourth embodiment of the present invention provides an air conditioner, which is based on the third embodiment and further comprises:

[0059] like Figure 1 and Figure 2 As shown, along the air supply direction of the air conditioner, the electric control box 108 is arranged on the side of the fan cavity 104, and the heat dissipation air duct 114 is arranged transversely to the air supply direction of the fan assembly 112. In this way, the relative position of the electric control box 108 and the fan cavity 104 is reasonably arranged in this embodiment, ensuring that the electric control box 108 does not affect the air supply of the fan assembly 112 in the fan cavity 104, and ensuring that there is no interference between the electric control box 108 and the fan cavity 104.

[0060] In addition, the heat dissipation duct 114 is arranged horizontally compared to the air supply direction of the fan assembly 112, and extends toward the location of the electrical control box 108 to ensure that the airflow in the heat exchange cavity 106 can enter the electrical control box 108 to dissipate heat for the electrical control box 108 and the electrical components 110 in the electrical control box 108.

[0061] In this technical solution, there is a gap between the inlet end of the heat dissipation duct 114 and the outlet end of the fan chamber 104 to ensure that there is a certain buffer space between the inlet end of the heat dissipation duct 114 and the outlet end of the fan chamber 104. In addition, this embodiment optimizes the structure of the support member 118 so that the mounting beam 116 is provided with a guide arc surface 122 at the inlet end of the heat dissipation duct 114.

[0062] In particular, if Figure 1 and Figure 2 As shown, due to the arrangement of the guide arc surface 122, the support member 118 can be prevented from forming a sharp point at the inlet end of the heat dissipation air duct 114, and the wind resistance of the support member 118 at the inlet end of the heat dissipation air duct 114 can be reduced, and the guide arc surface 122 can play a good guiding effect at the inlet end of the heat dissipation air duct 114. That is, during the operation of the air conditioner, the air in the heat exchange cavity 106 contacts the guide arc surface 122 at the inlet end of the heat dissipation air duct 114, and smoothly enters the heat dissipation air duct under the guiding effect of the guide arc surface 122, thereby increasing the amount of gas entering the heat dissipation air duct 114 per unit time, thereby improving the heat dissipation effect of the electric control box 108, and realizing efficient heat dissipation of the electric control box 108 and the electric control unit 110.

[0063] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0064] The fifth embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0065] The air conditioner further includes a heat exchanger 144. The heat exchanger 144 is disposed in the fan cavity 104 and can be in contact with the airflow in the heat exchange cavity 106 to exchange heat during the operation of the air conditioner, so as to realize the cooling and heating capabilities of the air conditioner.

[0066] In particular, if Figure 1 and Figure 2 As shown, the connection between the electric control box 108 and the fan cavity 104 is located on the side of the heat exchanger 144 facing the fan cavity 104. That is, it is ensured that the inlet end of the heat dissipation duct 114 is located on the 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 contacted the heat exchanger 144 for heat exchange, so the water vapor content in this part of the air is relatively low. Therefore, when this part of the airflow enters the electric control box 108, it can avoid moisture accumulation inside the electric control box 108, ensure that the air inside the electric control box 108 is relatively dry, and then ensure the service life of the electric control box 108 and the electric control unit 110.

[0067] In a specific embodiment, Figure 1 and Figure 2 As shown, the heat exchanger 144 is tiltedly arranged in the heat exchanger 144, and the side of the heat exchanger 144 facing the fan chamber 104 is ensured to be higher. In this way, it is ensured that there is a sufficient distance between the inlet end of the heat dissipation duct 114 and the heat exchanger 144, that is, it is ensured that there is a sufficient distance between the inlet end of the heat dissipation duct 114 and the heat exchanger 144, and the humidity of the gas entering the electric control box 108 is low, and it is ensured that the electric control box 108 and the electric control unit 110 will not be damaged by corrosion due to moisture.

[0068] In this embodiment, the housing 102 further includes a pipeline cavity 152, and the end of the refrigerant pipeline of the heat exchanger is located in the pipeline cavity 152, and can be connected to the external pipe in the refrigerant cavity to ensure the input and output of the refrigerant. In addition, the pipeline cavity 152 is isolated from the heat exchange cavity 106 by the support member 118, and the sealing of the pipeline cavity 152 is ensured by the support member 118, and the heat dissipation duct 114 is located between the pipeline cavity 152 and the electric control box 108. In this way, the support member 118 is used to isolate the pipeline cavity 152 and the heat exchange cavity 106 to ensure the sealing of the pipeline cavity 152, thereby avoiding the generation of condensation in the pipeline cavity 152; and the heat dissipation duct 114 is located between the pipeline cavity 152 and the electrical control box 108, ensuring that the support member 118 isolates the heat dissipation duct 114 from the pipeline cavity 152, while avoiding the airflow in the heat dissipation duct 114 from entering the pipeline cavity 152, thereby avoiding the generation of condensation in the pipeline cavity 152.

[0069] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0070] The sixth embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0071] like Figure 1 and Figure 2 As shown, the air conditioner further includes an air guide cover 126 . The air guide cover 126 is disposed in the fan cavity 104 and can play a good air guide role during the operation of the fan assembly 112 to guide the airflow generated by the fan assembly 112 to the heat exchange cavity 106 .

[0072] In this embodiment, further, Figure 2As shown, the air guide cover 126 includes an air supply port 128, and the air supply port 128 is designed toward the heat exchange cavity 106. In addition, a side wall 130 of the air guide cover 126 is formed with a guide slope 132 at the air supply port 128, so that the air supply port 128 presents a trumpet shape; at the same time, the guide slope 132 extends toward the connection between the heat exchange cavity 106 and the electric control box 108.

[0073] In this way, during the operation of the air conditioner, Figure 2 As shown, the airflow generated by the fan assembly 112 can be diffused when flowing out of the air supply port 128, so that at least part of the airflow is directed toward the connection between the heat exchange cavity 106 and the electrical control box 108, that is, at least part of the airflow flows toward the inlet end of the heat dissipation duct 114, which is beneficial to increase the amount of gas entering the electrical control box 108 per unit time, thereby improving the heat dissipation effect of the electrical control box 108.

[0074] It should be noted that the operation of the fan assembly 112 can deliver air to the heat exchange chamber 106. The accumulation of gas in the heat exchange chamber 106 will result in a higher pressure in the heat exchange chamber 106. At this time, the gas in the heat exchange chamber 106 can enter the electric control box 108. On this basis, the present embodiment provides a guide slope 132 so that part of the airflow delivered by the fan assembly 112 can flow directly to the connection between the heat exchange chamber 106 and the electric control box 108, thereby further improving the heat dissipation effect of the electric control box 108.

[0075] In this embodiment, further, Figure 2 As shown, the air guide cover 126 includes an air inlet 134. The air inlet 134 is arranged opposite to the air supply port 128, and the air inlet 134 is arranged toward the return air port 136 of the housing 102, and can inhale air from the outside. In addition, the electric control box 108 is located on the side of the air guide cover 126, and the heat dissipation air duct 114 is arranged horizontally. In this way, at least part of the airflow generated by the fan assembly 112 can be directly directed to the connection between the heat exchange cavity 106 and the electric control box 108.

[0076] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0077] The seventh embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0078] like Figure 1 and Figure 2As shown, the fan chamber 104 includes a return air port 136, and the heat exchange chamber 106 includes an air outlet 138. Among them, the air duct of the air conditioner is between the return air port 136 and the air outlet 138 (not shown in the figure). During the operation of the air conditioner, external air can enter the air duct through the return air port 136, and the air flow enters the heat exchange chamber 106 driven by the fan assembly 112, and is discharged from the air outlet 138. In particular, the electric control box 108 is arranged on the side of the air duct, and the electric control box 108 is connected to the part of the air duct located in the heat exchange chamber 106. In this way, it can be ensured that the air in the air duct enters the electric control box 108 driven by the pressure difference, so as to achieve the cooling of the electric control box 108.

[0079] In this embodiment, further, Figure 1 and Figure 2 As shown, the fan assembly 112 includes a connected wind wheel 140 and a driving member 142. The wind wheel 140 and the fan assembly 112 are both arranged in the fan cavity 104, and the wind wheel 140 is arranged in the air duct, and the driving member 142 is arranged between the wind wheel 140 and the electric control box 108. In this way, during the operation of the fan assembly 112, the driving member 142 drives the wind wheel 140 to rotate in the air duct, so that the wind wheel 140 supplies air to the heat exchange cavity 106. At this time, the pressure in the heat exchange cavity 106 is relatively high, while the pressure in the electric control box 108 is relatively low, so that the airflow in the heat exchange cavity 106 enters the electric control box 108 driven by the pressure difference, thereby realizing efficient heat dissipation of the electric control box 108.

[0080] In a specific embodiment, the driving member 142 is a motor, and the electric control box 108 includes a motor driving module, which is electrically connected to the motor and can be used to control the operation of the motor.

[0081] In addition, when the electrical control box 108 is connected to the fan cavity 104, the electrical control box 108 is connected to the position where the driving member 142 is located, and is connected to the outside of the air duct (because the interior of the air guide cover 126 is a partial air duct). At this time, the pressure at the position where the driving member 142 is located is relatively low, thereby ensuring that the gas in the electrical control box 108 can enter the fan cavity 104.

[0082] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner proposed in the first embodiment, and can ensure that the airflow in the heat exchange cavity 106 continuously enters the electrical control box 108 during operation, thereby efficiently dissipating the heat of the electrical control box 108 and the electrical control unit 110.

[0083] The eighth embodiment of the present invention provides an air conditioner, which is based on the first embodiment and further comprises:

[0084] like Figure 2As shown, the air conditioner further includes a filter device 146. The filter device 146 is disposed at the return air port 136 of the fan chamber 104 and is connected to the housing 102. In this way, during the operation of the air conditioner, the filter device 146 has a good filtering effect on impurities mixed in the air, thereby ensuring the cleanliness of the air entering the housing 102, and further ensuring the cleanliness of the air entering the electric control box 108.

[0085] In particular, the electric control unit 110 in the electric control box 108 is generally a precision component and is relatively expensive. In this embodiment, on the basis of utilizing the gas in the heat exchange cavity 106 to dissipate heat from the electric control box 108 and the electric control unit 110, a filter device 146 is provided at the return air port 136 of the air conditioner, which can effectively reduce or prevent dust from entering the electric control box 108, thereby ensuring the cleanliness of the electric control box 108 and the service life of the electric control unit 110.

[0086] Specifically, the filter device 146 can be a filter. In addition, the filter device 146 is detachably installed at the return air outlet 136, which is convenient for users to replace, repair and clean.

[0087] In any of the above embodiments, on the basis that the electric control box 108 is connected to the heat exchange chamber 106, the electric control box 108 may also be connected to the fan chamber 104, or to the external environment, or to both the fan chamber 104 and the external environment; the following is divided into three cases for discussion:

[0088] Case 1: If Figure 5 As shown, the electric control box 108 is connected to the fan chamber 104 and the heat exchange chamber 106. In this way, the fan assembly 112 can supply air to the heat exchange chamber 106 during operation, which increases the pressure in the heat exchange chamber 106 and is higher than the pressure in the electric control box 108 and the fan chamber 104. At this time, driven by the pressure difference, the gas in the heat exchange chamber 106 enters the electric control box 108, and then the gas in the electric control box 108 can enter the fan chamber 104, thereby forming a heat dissipation flow path. In this way, the airflow entering the electric control box 108 can effectively dissipate the heat of the electric control box 108 and the electric control unit 110 in the electric control box 108, and when the air in the electric control box 108 flows to the fan chamber 104, the heat in the electric control box 108 can also be brought to the fan chamber 104, thereby achieving further heat dissipation of the electric control box 108 and greatly improving the heat dissipation effect of the electric control box 108.

[0089] And, if Figure 5As shown, when the electric control box 108 is connected with the fan cavity 104 and the heat exchange cavity 106, the electric control box 108 is provided with a first heat dissipation hole 120 and a second heat dissipation hole 124; wherein, the electric control box 108 is connected with the heat exchange cavity 106 through the first heat dissipation hole 120, and the electric control box 108 is connected with the fan cavity 104 through the second heat dissipation hole 124. Moreover, the gas entering the fan cavity 104 can be blown toward the heat exchange cavity 106 again, and this part of the gas can be blown out after heat exchange, and the temperature of the electric control box 108 can be cooled again.

[0090] Case 2: The electric control box 108 is connected to the heat exchange chamber 106 and the external environment. In this way, the fan assembly 112 can supply air to the heat exchange chamber 106 during operation, which increases the pressure in the heat exchange chamber 106 and is higher than the pressure of the electric control box 108 and the external environment. At this time, driven by the pressure difference, the gas in the heat exchange chamber 106 enters the electric control box 108, and then the gas in the electric control box 108 can enter the external environment, thereby forming an air flow path. In this way, the airflow entering the electric control box 108 can effectively dissipate the heat of the electric control box 108 and the electric components 110 in the electric control box 108, and when the air in the electric control box 108 flows to the external environment, it can also bring the heat in the electric control box 108 to the external environment, thereby achieving further heat dissipation of the electric control box 108 and greatly improving the heat dissipation effect of the electric control box 108.

[0091] Furthermore, when the electric control box 108 is connected to the heat exchange cavity 106 and the external environment, the electric control box 108 is provided with a first heat dissipation hole 120 and a third heat dissipation hole; wherein the electric control box 108 is connected to the heat exchange cavity 106 through the first heat dissipation hole 120, and the electric control box 108 is connected to the external environment through the third heat dissipation hole. Furthermore, this part of air will not participate in the heat dissipation of the electric control box 108 again.

[0092] Case 3: The electric control box 108 is connected to the heat exchange chamber 106, the fan chamber 104 and the external environment. In this way, the fan assembly 112 can supply air to the heat exchange chamber 106 during operation, which increases the pressure in the heat exchange chamber 106 and is higher than the pressure in the electric control box 108 and the fan chamber 104, and is also higher than the pressure in the external environment. At this time, driven by the pressure difference, the gas in the heat exchange chamber 106 enters the electric control box 108, and then the gas in the electric control box 108 can enter the fan chamber 104 and the external environment, thereby forming two branches. In this way, the airflow entering the electrical control box 108 can effectively dissipate the heat of the electrical control box 108 and the electrical components 110 in the electrical control box 108, and when the air in the electrical control box 108 flows to the fan cavity 104 and the external environment, the heat in the electrical control box 108 can also be brought to the external environment, thereby further dissipating the heat of the electrical control box 108 and greatly improving the heat dissipation effect of the electrical control box 108.

[0093] Furthermore, the electric control box 108 is provided with a first heat dissipation hole 120, a second heat dissipation hole 124, and a third heat dissipation hole; wherein, the electric control box 108 is connected to the heat exchange cavity 106 through the first heat dissipation hole 120, the electric control box 108 is connected to the fan cavity 104 through the second heat dissipation hole 124, and the electric control box 108 is connected to the external environment through the third heat dissipation hole. Moreover, this part of the air will not participate in the heat dissipation of the electric control box 108 again. In addition, the part of the air that enters the fan cavity 104 can be blown to the heat exchange cavity 106 again, and this part of the gas can be blown out after heat exchange, and can also cool the electric control box 108 again; the part of the air that enters the external environment will not participate in the heat dissipation of the electric control box 108 again.

[0094] In a specific embodiment, when the electrical control box 108 is connected to the fan cavity 104, since the fan assembly 112 is disposed in the fan cavity 104, the fan assembly 112 can further reduce the pressure in the fan cavity 104 during operation, thereby making the pressure in the fan cavity 104 lower than the pressure in the first electrical control box 108, further prompting the air in the electrical control box 108 to enter the fan cavity 104, so as to further improve the heat dissipation efficiency of the electrical control box 108.

[0095] In a specific embodiment, Figure 5 As shown, the electric control box 108 may be provided with a plurality of folded edges, so that the positions of the folded edges form the above-mentioned first heat dissipation holes 120. In addition, the number of the first heat dissipation holes 120 may be one or more, and is designed according to the air volume required for the actual heat dissipation of the electric control box 108. When the air volume required for the heat dissipation of the electric control box 108 is large, more first heat dissipation holes 120 may be designed. In addition, the shape of the first heat dissipation holes 120 may be designed according to actual conditions, and may be circular, elliptical, triangular, rectangular or other irregular shapes. And, the above content is understandable to those skilled in the art.

[0096] In a specific embodiment, the electric control box 108 may be provided with a plurality of folded edges, so that the positions of the folded edges form the second heat dissipation holes 124. In addition, the number of the second heat dissipation holes 124 may be one or more, and is designed according to the air volume required for heat dissipation of the actual electric control box 108. When the air volume required for heat dissipation of the electric control box 108 is large, more second heat dissipation holes 124 may be designed. In addition, the shape of the second heat dissipation holes 124 may be designed according to actual conditions, and may be circular, elliptical, triangular, rectangular or other irregular shapes. Moreover, the above content is understandable to those skilled in the art.

[0097] In a specific embodiment, the electric control box 108 may be provided with a plurality of folded edges so that the third heat dissipation holes are formed at the positions of the folded edges. In addition, the number of the third heat dissipation holes may be one or more, and is designed according to the air volume required for heat dissipation of the actual electric control box 108. When the air volume required for heat dissipation of the electric control box 108 is large, more third heat dissipation holes may be designed. In addition, the shape of the third heat dissipation hole may be designed according to actual conditions, and may be circular, elliptical, triangular, rectangular or other irregular shapes. Moreover, the above contents are understandable to those skilled in the art.

[0098] In any of the above embodiments, the electric control unit 110 includes a motor drive module and can be used to drive the motor of the air conditioner. In particular, the motor drive module generates heat during the operation of the driving motor. If the motor drive module is designed together with the motor, the cost of the entire motor will be too high. Therefore, the present invention sets the motor drive module in the electric control box 108 and dissipates heat through the airflow in the heat exchange cavity 106, which reduces the cost of the motor and the air conditioner while solving the heat dissipation problem of the motor drive module and the electric control box 108.

[0099] In any of the above embodiments, if Figure 3 As shown, the electric control box 108 includes a box body 148 and a cover 150 . The box body 148 can be an integrated structure with the housing 102 , and the cover 150 is covered on the box body 148 .

[0100] The first specific embodiment of the present invention proposes an air conditioner, comprising: a housing 102, an electric control box 108, an electric control unit 110 and a fan assembly 112. The fan assembly 112 can supply air to the heat exchange chamber 106 during operation, which increases the pressure in the heat exchange chamber 106 and is higher than the pressure in the electric control box 108. Therefore, during the operation of the air conditioner, due to a certain pressure difference between the heat exchange chamber 106 and the electric control box 108, at least part of the gas in the heat exchange chamber 106 enters the electric control box 108, and returns to the fan chamber 104 after passing through the electric control box 108. The airflow passing through the electric control box 108 can effectively dissipate the heat of the electric control box 108 and the electric control unit 110 in the electric control box 108, thereby ensuring that the temperature in the electric control box 108 is appropriate, and the temperature of the electric control unit 110 is reduced, thereby ensuring the safety of the use of the electric control box 108 and the electric control unit 110.

[0101] In this embodiment, the electric control box 108 is further provided with a first heat dissipation hole 120 and a second heat dissipation hole 124. The first heat dissipation hole 120 is connected to the heat exchange cavity 106 to ensure that the airflow in the heat exchange cavity 106 can enter the electric control box 108; the second heat dissipation hole 124 is connected to the fan cavity 104 to ensure that the airflow in the electric control box 108 can enter the fan cavity 104.

[0102] In this embodiment, the air conditioner further includes a heat dissipation duct 114, and the heat exchange cavity 106 and the electric control box 108 are connected through the heat dissipation duct 114. Specifically, the inlet end of the heat dissipation duct 114 is located at the connection point between the fan cavity 104 and the heat exchange cavity 106, ensuring that the inlet end of the heat dissipation duct 114 is at a certain distance from the heat exchanger 144 in the heat exchange cavity 106. In addition, the air conditioner also includes a mounting beam 116 and a support member 118, and there is a certain space between the mounting beam 116 and the support member 118, and the heat dissipation duct 114 is directly formed by the space between the mounting beam 116 and the support member 118. In addition, along the air supply direction of the air conditioner, the electric control box 108 is arranged on the side of the fan cavity 104, and the heat dissipation duct 114 is arranged transversely compared to the air supply direction of the fan assembly 112. In addition, there is a gap between the inlet end of the heat dissipation duct 114 and the outlet end of the fan chamber 104 , and the mounting beam 116 is provided with a guide arc surface 122 at the inlet end of the heat dissipation duct 114 .

[0103] In this embodiment, the air conditioner further includes a heat exchanger 144, which is arranged in the fan cavity 104, and the connection point between the electric control box 108 and the fan cavity 104 is located on the 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 contacted the heat exchanger 144 for heat exchange. When this part of the airflow enters the electric control box 108, it can avoid the accumulation of moisture inside the electric control box 108, ensuring that the air inside the electric control box 108 is relatively dry, thereby ensuring the service life of the electric control box 108 and the electric control unit 110. In addition, the housing 102 also includes a pipeline cavity 152, and the end of the refrigerant pipeline of the heat exchanger is located in the pipeline cavity 152, and can be connected with the external pipe in the refrigerant cavity to ensure the input and output of the refrigerant, and the pipeline cavity 152 is isolated from the heat exchange cavity 106 by the support member 118.

[0104] In this embodiment, further, the air conditioner also includes an air guide cover 126, the air guide cover 126 includes an air supply port 128, and the side wall 130 of the air guide cover 126 is formed with a guide slope 132 at the air supply port 128, so that the air supply port 128 presents a trumpet shape. In addition, the air guide cover 126 includes an air inlet 134. Among them, the air inlet 134 is arranged opposite to the air supply port 128, the air inlet 134 is arranged toward the return air port 136 of the housing 102, the electric control box 108 is located on the side of the air guide cover 126, and the heat dissipation air duct 114 is arranged horizontally. In addition, the fan cavity 104 includes a return air port 136, the heat exchange cavity 106 includes an air outlet 138, the air duct of the air conditioner is between the return air port 136 and the air outlet 138, and the electric control box 108 is arranged on the side of the air duct. In addition, the fan assembly 112 includes a connected wind wheel 140 and a driving member 142.

[0105] In this embodiment, the air conditioner further includes a filter device 146. The filter device 146 is disposed at the return air port 136 of the fan chamber 104 and is connected to the housing 102. The filter device 146 has a good filtering effect on impurities mixed in the air, thereby ensuring the cleanliness of the air entering the housing 102, and further ensuring the cleanliness of the air entering the electric control box 108.

[0106] In a specific embodiment, electric control components such as motor drive modules generate heat during use. In the related art, heat dissipation components such as aluminum are set in the electric control box, but the heat dissipation efficiency is often low, and the heat dissipation problem of the electric control components and the electric control box cannot be effectively solved, and the electric control components are easily damaged. The air conditioner proposed in the present invention can effectively solve the heat dissipation problem of electric control components 110 such as motor drive modules, and can realize dust and moisture resistance inside the electric control box 108.

[0107] The air conditioner proposed by the present invention is as follows Figure 1 , Figure 2 and Figure 3 As shown, a heat dissipation duct 114 is formed between the support member 118 and the mounting beam 116, and the heat dissipation duct 114 communicates with the heat exchange chamber 106 and the electric control box 108. During the operation of the air conditioner, since the fan assembly 112 continuously supplies air to the heat exchange chamber 106, the air pressure in the heat exchange chamber 106 is relatively high, and the air pressure in the fan chamber 104 where the fan assembly 112 is located, the inside of the electric control box 108 and the external environment is relatively low. Therefore, the air in the heat exchange chamber 106 will enter the fan chamber 104 to improve the heat dissipation of the electric control box 108 and the electric control unit 110.

[0108] In addition, if Figure 5 As shown, a first heat dissipation hole 120 can be provided on the side of the electrical control box 108 facing the heat exchange cavity 106 to ensure that the airflow in the heat exchange cavity 106 enters the electrical control box 108 through the first heat dissipation hole 120; a second heat dissipation hole 124 is provided on the side of the electrical control box 108 facing the fan cavity 104 to ensure that the airflow in the electrical control box 108 flows back to the fan cavity 104 through the second heat dissipation hole 124 and takes away the heat inside the electrical control box 108, thereby further improving the heat dissipation effect on the electrical control box 108 and the electrical components 110.

[0109] In addition, a third heat dissipation hole may be provided in the electric control box 108 to ensure that the airflow in the electric control box 108 enters the external environment through the third heat dissipation hole. At this time, the air in the electric control box 108 can also flow to the external environment and take away the heat inside the electric control box 108, further improving the heat dissipation effect of the electric control box 108 and the electric control unit 110.

[0110] In addition, if Figure 2As shown, a filter device 146 is provided at the return air port 136 of the fan chamber 104. In this way, the impurity content in the air entering the air conditioner is low, which ensures the cleanliness of the air entering the housing 102 and the cleanliness of the air entering the electric control box 108.

[0111] In addition, if Figure 1 and Figure 2 As shown, a heat exchanger 144 is provided in the fan cavity 104, and the inlet end of the heat dissipation duct 114 is ensured to be located on the side of the heat exchanger 144 facing the fan cavity 104. In this way, the air entering the heat dissipation duct 114 and the electric control box 108 does not exchange heat with the heat exchanger 144, and the water vapor content in this part of the air is low, which can avoid moisture accumulation inside the electric control box 108, ensure that the air inside the electric control box 108 is relatively dry, and further ensure the service life of the electric control box 108 and the electric control unit 110.
