DETAILED DESCRIPTION

[0034] As disclosed in the background technology, the prior art heat dissipation structure for the motor is usually to directly open a heat dissipation hole on the base or the middle frame, and the heat dissipation hole is connected to the motor through the internal heat dissipation channel, so as to take away the heat generated by the motor. However, this setting method has two disadvantages. The first is that the hole is opened directly on the outside. After the air conditioner is mounted on the wall, the heat dissipation hole can be directly seen from the user's perspective, and the inside of the heat dissipation hole is a large-sized cavity structure. When there is no light inside, the heat dissipation hole will present a large range of black shadows, which is in sharp contrast with the usual white appearance of the air conditioner, making the air conditioner poor in integrity and affecting its aesthetics. The second is that the heat dissipation hole usually uses natural convection to discharge the gas in the inner cavity, which causes the hot air generated by the motor to be discharged slowly and easily converge, resulting in poor heat dissipation effect.

[0035] In order to solve the above problems, the present invention provides an air conditioning motor heat dissipation structure and an air conditioner. In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] First embodiment

[0037] See also Figures 1 to 6 The present embodiment provides an air conditioner motor heat dissipation structure 100, which can improve the heat dissipation effect and the overall aesthetics through reasonable structural settings.

[0038] The present embodiment provides an air-conditioning motor heat dissipation structure 100, including a base 110 and a middle frame 130. The base 110 is provided with a receiving groove 111 for installing a motor 200. The bottom wall of the receiving groove 111 is provided with heat dissipation holes 113. The base 110 is also provided with an air duct 117 for discharging air toward the front, and a molding groove 115 is also provided on the side away from the air outlet direction. The heat dissipation holes 113 are connected to the molding groove 115. The middle frame 130 is installed on the base 110, and an air outlet 190 corresponding to the air duct 117 is provided at the bottom. The base 110 is also provided with an air duct side plate 150. One side surface of the air duct side plate 150 is configured as a side wall of the air duct 117, and the other side surface is connected to the molding groove 115. The air duct side plate 150 is also provided with an air outlet hole 151. The air outlet hole 151 connects the molding groove 115 and the air duct 117 for discharging the gas in the molding groove 115.

[0039] It should be noted that the air conditioner motor heat dissipation structure 100 provided in this embodiment is suitable for an air conditioner wall mounted unit, wherein the basic structure and working principle of the air conditioner wall mounted unit are consistent with those of a conventional air conditioner indoor wall mounted unit, and no further introduction is given here. Among them, the air duct side plate 150 can be a side plate structure in the air duct 117 close to the motor side, which can be engaged with the forming groove 115, thereby ensuring that the air outlet hole 151 is connected to the air duct 117 of the forming groove 115. In addition, the extension direction of the air duct side plate 150 is parallel to the air outlet direction of the air duct 117, so it is difficult to see the air duct side plate 150 from the perspective of the air outlet direction of the air duct 117, and it is also difficult to see the air outlet hole 151 on the air duct side plate 150.

[0040] In this embodiment, the motor is installed by setting a receiving groove 111, and a heat dissipation hole 113 is opened at the bottom of the receiving groove 111, and the heat dissipation hole 113 is connected to the molding groove 115, so that the heat generated by the motor is transferred to the molding groove 115. At the same time, a duct side plate 150 is also provided on the base 110, and the two side surfaces of the duct side plate 150 are respectively connected to the duct 117 and the molding groove 115, and the duct side plate 150 is provided with an air outlet 151, and the air outlet 151 can discharge the gas in the molding groove 115, so as to achieve heat dissipation. In addition, in this embodiment, the air outlet 151 is opened on the duct side plate 150. On the one hand, the opening position of the air outlet 151 is concealed, and the user is not easy to see the air outlet 151 under normal viewing angle, which improves the integrity and aesthetics of the air conditioner. On the other hand, the air duct 117 can be used to generate negative pressure outside the air outlet 151 to quickly discharge the hot air in the molding groove 115, so as to achieve rapid heat dissipation and improve the heat dissipation effect.

[0041] In this embodiment, a windshield 153 is also provided on the surface of one side of the duct side plate 150 close to the duct 117, and the windshield 153 is provided on the side of the air outlet 151 away from the air outlet 190. Specifically, the windshield 153 can be integrally provided on the duct side plate 150, and protrude toward the center of the duct 117, so as to disturb the airflow at the edge of the duct 117. In addition, in order to avoid too large a range of disturbance of the air outlet of the duct 117, the protrusion height of the windshield 153 can be set, and an inclined surface or curved surface structure can be provided on the windward side. In this embodiment, by providing the windshield 153 on the duct side plate 150, the windshield 153 can prevent the wind in the duct 117 from entering the air outlet 151 to cause reverse perfusion during the air outlet process, thereby ensuring that the air outlet 151 is in the air outlet state and ensuring the heat dissipation effect.

[0042] It should be noted that the setting range of the wind shield 153 needs to completely cover the air outlet 151. Therefore, in the vertical direction, the width of the wind shield 153 can be greater than or equal to the width of the air outlet 151 to shield the air outlet 151 as much as possible.

[0043] In this embodiment, the air outlet hole 151 includes a plurality of strip holes, and the plurality of strip holes are arranged in parallel on the air duct side plate 150. By providing a plurality of strip holes, the air outlet area can be increased, the heat dissipation effect can be improved, and the plurality of strip holes are arranged in parallel, which can ensure uniform air flow and avoid local turbulence that affects the normal air outlet of the air duct 117.

[0044] It should be noted that, in this embodiment, the extension directions of the plurality of strip holes are parallel to each other, and the extension direction of each strip hole is perpendicular to the air outlet direction of the air duct 117. By setting the extension direction of the strip holes and the air outlet direction of the air duct 117 to be perpendicular, that is, the strip holes are substantially extended in the vertical direction, the structural strength of the air duct side plate 150 can be ensured in the vertical direction, the upper and lower support strength can be ensured, and at the same time, the opening range of the strip holes facing the air outlet direction of the air duct 117 can be made smaller, further preventing the gas in the air duct 117 from pouring into the air outlet hole 151.

[0045] In this embodiment, an air inlet hole 131 is further provided on the bottom side of the middle frame 130, and the air inlet hole 131 connects the external space with the molding groove 115, and is used to replenish gas to the molding groove 115. Specifically, the air inlet hole 131 is located on the bottom side surface of the middle frame 130 and is connected to the molding groove 115, which can ensure that there is enough gas in the molding groove 115 for suction at the air outlet hole 151. By providing the air inlet hole 131, when the gas in the molding groove 115 is extracted from the air outlet hole 151, cold air can be replenished from the outside, so that the air inlet hole 131 and the air outlet hole 151 form a circulating heat dissipation flow channel, realize convection heat dissipation, further improve the air outlet speed of the air outlet hole 151, quickly discharge the hot air in the molding groove 115, and improve the heat dissipation efficiency.

[0046] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 In this embodiment, a shielding plate 170 is further provided on the base 110. The shielding plate 170 extends to the molding groove 115 and is spaced and arranged opposite to the air inlet hole 131 to shield the air inlet hole 131. The shielding plate 170 extends backward and shields the air inlet hole 131. By providing the shielding plate 170, the air inlet hole 131 can be shielded from the inside, so that the color presented on the outside of the air inlet hole 131 is close to the color of the shielding plate 170, avoiding the formation of a large area of ​​shadow at the air inlet hole 131, thereby improving the integrity of the air conditioner and further ensuring the overall aesthetics. In addition, by providing the shielding plate 170, the airflow in the molding groove 115 can be blocked, so that the cold air supplemented from the outside can be fully mixed with the hot air transmitted by the motor in the molding groove 115 and then discharged from the air outlet 151, thereby ensuring the heat dissipation effect.

[0047] It should be noted that in this embodiment, the shielding plate 170 is integrally provided on the base 110, and the color of the shielding plate 170 and the color of the middle frame 130 are both white, thereby achieving a black-shielding effect. Of course, in other preferred embodiments of the present invention, the shielding plate 170 can also be integrally provided on the middle frame 130, and also extend backward to the top of the air inlet 131, and also achieve a black-shielding effect.

[0048] The middle frame 130 includes a surrounding plate 133 and a bottom plate 135, the air outlet 190 is arranged at the bottom of the surrounding plate 133, the bottom plate 135 is arranged at the bottom side of the surrounding plate 133, and the front end of the bottom plate 135 is connected to the bottom side edge of the air outlet 190, the rear end of the bottom plate 135 extends to the molding groove 115, the air inlet 131 is opened on the bottom plate 135, and the shielding plate 170 is arranged at intervals from the bottom plate 135. Specifically, the air inlet 131 is opened on the bottom plate 135, so that the air inlet 131 can be located at the lowest end of the whole, and there is no shielding at the bottom of the bottom plate 135, so as to facilitate the rapid replenishment of external cold air, and at the same time, the shielding plate 170 and the bottom plate 135 are arranged at intervals, while ensuring the blackening effect, it can leave enough gas circulation space to ensure the circulation convection effect of the air inlet 131 and the air outlet 151.

[0049] It should be noted that in order to ensure a good black-shielding effect, the spacing distance between the mask plate 170 and the bottom plate 135 can be less than or equal to 10 mm and greater than or equal to 3 mm, which can ensure a good black-shielding effect while also ensuring sufficient heat dissipation channels to ensure heat dissipation effects.

[0050] In this embodiment, the base 110 is further provided with a front side plate 119, the front side surface of the front side plate 119 corresponds to one end edge of the air outlet 190, the rear side surface of the front side plate 119 is connected to the molding groove 115, the air duct side plate 150 is connected to the side of the front side plate 119 close to the air duct 117, the front end of the bottom plate 135 is provided with an upper folding plate 137 bent and extended toward the air duct 117, the upper folding plate 137 extends to the front side surface of the front side plate 119, and abuts and cooperates with the front side plate, and one end of the shielding plate 170 is connected to the front side plate 119. Specifically, the shielding plate 170 is integrally connected to the bottom side edge of the front side plate 119 and is bent and extended backward. Of course, the shielding plate 170 can also be integrally provided on the upper folding plate 137 and bend and extend backward. In this embodiment, by setting the front side panel 119 and the upper folding plate 137, a false air outlet structure can be formed at one end edge of the air outlet 190 to improve the overall aesthetics and integrity. The upper folding plate 137 is bent and extended to the air duct 117, and the air duct side panel 150 and one side edge of the front side panel 119. Such a setting can further ensure smooth air outlet of the air duct 117.

[0051] In this embodiment, a support plate 171 is provided on at least one side edge of the shielding plate 170, and the support plate 171 is bent toward the bottom plate 135 and abuts against the bottom plate 135. Specifically, a support plate 171 is provided on one side edge of the shielding plate 170 away from the front side plate 119, and the support plate 171 is bent downward and perpendicular to the shielding plate 170, so that sufficient air circulation space can be left on the left and right sides of the shielding plate 170 to ensure the heat dissipation effect. In addition, by providing the support plate 171, the shielding plate 170 can be supported, and the structural strength of the shielding plate 170 can be improved.

[0052] It should be noted that, in other preferred embodiments of the present invention, the support plate 171 may also be disposed on the left and right sides of the shielding plate 170 , so as to achieve a better supporting effect.

[0053] In this embodiment, the air inlet 131 includes a plurality of through holes arranged in an array, and the projection of the shielding plate 170 on the bottom plate 135 covers the plurality of through holes. Specifically, the plurality of through holes are all circular holes, thereby ensuring the structural strength of the opening. In addition, the support plate 171 and the plurality of through holes are misaligned to avoid the support plate 171 blocking the plurality of through holes. Moreover, by providing a plurality of through holes arranged in an array, the air inlet area can be increased, thereby improving the convective heat dissipation effect, and at the same time, the shielding plate 170 can completely block the plurality of through holes to ensure the shielding effect.

[0054] In summary, the air conditioner motor heat dissipation structure 100 provided in this embodiment is to install the motor by setting a receiving groove 111, and a heat dissipation hole 113 is opened at the bottom of the receiving groove 111, and the heat dissipation hole 113 is connected to the molding groove 115, so as to transfer the heat generated by the motor to the molding groove 115. At the same time, the base 110 is also provided with a duct side plate 150, and the two side surfaces of the duct side plate 150 are respectively connected with the duct 117 and the molding groove 115, and the duct side plate 150 is provided with an air outlet hole 151, and the air outlet hole 151 can discharge the gas in the molding groove 115, so as to achieve heat dissipation. Compared with the prior art, this embodiment achieves heat dissipation by opening the air outlet hole 151 on the air duct side plate 150. On the one hand, the opening position of the air outlet hole 151 is concealed, and the user is not easy to see the air outlet hole 151 under normal viewing angle, which improves the integrity and aesthetics of the air conditioner.

In addition, by opening the air inlet 131 on the bottom plate 135, the air inlet 131 and the air outlet 151 can form a cyclic convection heat dissipation, further improving the heat dissipation effect.
