DETAILED DESCRIPTION

[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] like Figure 1-Figure 13 As shown, an embodiment of the present application provides a heat exchanger side plate 1 that can be fixed to the end of the heat exchanger body 3 , such as: can be fixed to the left end or the right end of the heat exchanger body 3 .

[0035] The heat exchanger side plate 1 comprises a side plate body 11 and a grounding portion 12 which are fixedly connected.

[0036] The grounding portion 12 is provided with a fixing portion 121 and a limiting portion 122. The fixing portion 121 is configured to fix the ground wire 4. For example, the ground wire 4 can be fixed to the fixing portion 121 by a screw 5. The setting of the ground wire 4 ensures the safe operation and use safety of the indoor unit of the air conditioner.

[0037] The limiting portion 122 is configured to limit the ground wire 4 along the circumferential direction of the fixing portion 121. When the ground wire 4 is installed, the ground wire 4 may rotate around the fixing portion 121 along the circumferential direction of the fixing portion 121 as the screw 5 is screwed. When the ground wire 4 rotates to abut against the limiting portion 122, the ground wire 4 is blocked by the limiting portion 122, so that the ground wire 4 no longer rotates. Therefore, the limiting portion 122 plays a positioning role for the ground wire 4, which helps to install the ground wire 4 at the expected position, avoiding malfunctions and affecting the safety of the air conditioner operation.

[0038] In the embodiment of the present application, by setting a limiter 122 on the heat exchanger side plate 1, when installing the ground wire 4, the ground wire 4 is positioned at a certain position in the circumferential direction of the fixing portion 121. By setting the limiter 122 at an appropriate position, the ground wire 4 can be positioned at an appropriate position. When the ground wire 4 is at the appropriate position, it helps the condensed water flow along the ground wire 4 to a lower place and finally fall into the chassis water tank, avoiding line failure and affecting the safety of the air conditioner operation.

[0039] In some exemplary embodiments, Figure 1 , Figure 3-Figure 8 , Fig.11 and Fig.13 As shown, the limiting portion 122 includes a stop protrusion, and the stop protrusion is configured to contact and cooperate with the outer wall surface of the ground wire 4 to perform limiting.

[0040] The stopper protrusion may be located in the rotation path of the connection head of the ground wire 4 around the fixing portion 121, blocking the outer wall of the connection head of the ground wire 4 from one side, so that the ground wire 4 no longer rotates. The stopper protrusion may be of any suitable shape as long as it can block the rotation of the ground wire 4. The stopper protrusion and the grounding portion 12 may be integrally formed, such as the stopper protrusion may be formed by stamping a portion of the grounding portion 12. Of course, the stopper protrusion and the grounding portion 12 may also be formed separately and fixedly connected to the grounding portion 12.

[0041] In some exemplary embodiments, Figure 1 , Figure 3-Figure 4 , Figure 8 , Fig.11 and Fig.13 As shown, at least one limiting portion 122 and one fixing portion 121 are provided, and they are arranged in a one-to-one correspondence. The limiting portion 122 is located below the corresponding fixing portion 121 and faces the side close to the side plate body 11 .

[0042] The grounding portion 12 can be arranged on the side of the side plate body 11 close to the heat exchanger body 3, such as when the heat exchanger side plate 1 is arranged on the right side of the heat exchanger body 3, the grounding portion 12 can be arranged on the left side of the side plate body 11. On the grounding portion 12, at least one limiting portion 122 and a fixing portion 121 are each provided, such as four limiting portions 122 and four fixing portions 121 can be each provided (or other number), and the four limiting portions 122 and the four fixing portions 121 are arranged one by one. The limiting portion 122 is located below the corresponding fixing portion 121, and is biased toward the side close to the side plate body 11 (i.e., the side away from the heat exchanger body 3, the ground wire 4 is led out toward this side), therefore, the limiting portion 122 is located obliquely below the corresponding fixing portion 121.

[0043] When installing the ground wire 4, the ground wire 4 rotates as the screw 5 is screwed, and after rotating to a certain angle, it contacts the stopper 122, thereby preventing the ground wire 4 from continuing to rotate and positioning the ground wire 4 there. The position of the stopper 122 can make the routing direction of the ground wire 4 obliquely downward, for example, the ground wire 4 is kept tilted downward at an angle of 45 degrees (or other angles), which is conducive to the condensed water flowing through the ground wire 4 to the chassis water tank, preventing the danger of line short circuit and the like.

[0044] In some exemplary embodiments, Figure 1 , Figure 3-Figure 4 , Figure 7-Figure 8 , Fig.11 and Fig.13 As shown, the fixing portion 121 includes a threaded hole, so that the ground wire 4 is fixed to the threaded hole by a screw 5. Fixing the ground wire 4 by the screw 5 makes the disassembly and assembly of the ground wire 4 convenient on the one hand, and helps to ensure the electrical connection between the ground wire 4 and the side plate 1 of the heat exchanger on the other hand.

[0045] When assembling the ground wire 4, the ground wire 4 is fixed in the threaded hole by screwing the screw 5. In the process of screwing the screw 5, the ground wire 4 rotates with the screwing of the screw 5 until the ground wire 4 contacts the stopper 122, after which the ground wire 4 no longer rotates with the screw 5, thereby positioning the ground wire 4 at that position.

[0046] It should be understood that the ground wire 4 is not limited to being fixed to the fixing portion 121 by the screw 5 , and the ground wire 4 may also be fixed by other means.

[0047] In some exemplary embodiments, Figure 1-Figure 2 , Figure 4 , Figure 6 and Figure 11-Figure 12 As shown, the heat exchanger side plate 1 further includes a first folded edge 13 disposed on one side of the side plate body 11 , and the first folded edge 13 is configured to cooperate with the limiting sliding groove 211 of the motor cover 21 of the air conditioner indoor unit 100 .

[0048] The heat exchanger side plate 1 can be half-wrapped around the motor cover 21, and a first folded edge 13 is provided on one side (e.g., the lower side) of the side plate body 11 adjacent to the motor cover 21, and the first folded edge 13 extends from the side plate body 11 toward the side away from the heat exchanger body 3. The motor cover 21 is arranged on the outside of the motor of the air conditioner indoor unit 100, and the motor cover 21 can prevent the condensed water generated by the heat exchanger body 3 from dripping onto the motor. At least part of the first folded edge 13 extends into the limiting slide groove 211 of the motor cover 21, so that the displacement of the heat exchanger side plate 1 and the heat exchanger body 3 relative to the motor cover 21 is limited by the cooperation of the first folded edge 13 and the limiting slide groove 211.

[0049] An edge of the first folded edge 13 adjacent to the side plate body 11 (e.g., the front edge or rear edge of the first folded edge 13 ) is provided with a flange 14 , which is configured to be folded toward a side away from the inner bottom surface 2111 of the limiting slide groove 211 , such as: the flange 14 can be folded upward.

[0050] When assembling the heat exchanger, if the edge of the first folded edge 13 (such as the front edge or the rear edge of the first folded edge 13) is not provided with a flange 14, the edge of the first folded edge 13 is in direct contact with the inner bottom surface 2111 of the limiting slide groove 211, and then scrapes the inner bottom surface 2111 of the limiting slide groove 211. In the embodiment of the present application, since the edge of the first folded edge 13 (such as the front edge or the rear edge of the first folded edge 13) is provided with a flange 14, and the flange 14 is folded upward, the upward edge of the flange 14 does not directly contact the inner bottom surface 2111 of the motor cover 21, thereby preventing the edge of the first folded edge 13 from scraping the inner bottom surface 2111 of the motor cover 21 during the assembly process.

[0051] In some exemplary embodiments, Figure 2 and Fig.12As shown, the surface of the flange 14 disposed opposite to the inner bottom surface 2111 of the limiting slide groove 211 is a curved surface 141, and the surface of the first folded edge 13 disposed opposite to the inner bottom surface 2111 of the limiting slide groove 211 can be configured to be smoothly transitionally connected to the curved surface 141. The side of the flange 14 close to the inner bottom surface 2111 of the limiting slide groove 211 is configured as the curved surface 141, and is smoothly transitionally connected to the first folded edge 13 on this side, so as to avoid the formation of a sharp connecting edge between the first folded edge 13 and the flange 14 on the side close to the inner bottom surface of the limiting slide groove 211, so as to prevent the sharp connecting edge from scratching the limiting slide groove 211 of the motor cover 21 and causing damage.

[0052] In some exemplary embodiments, Figure 1-Figure 6 , Figure 10-13 As shown, the side plate body 11 includes a first portion 114 adjacent to the flange 14, and the first portion 114 is provided with a guide portion 1141 inclined toward the side where the first folded edge 13 is located (the side away from the heat exchanger body 3), and the guide portion 1141 is configured to cooperate with the inner wall surface 2112 of the limiting slide groove 211 to guide the first folded edge 13 to cooperate with the limiting slide groove 211.

[0053] During assembly, the guide portion 1141 can gradually slide into the limiting slide groove 211 as the heat exchanger side plate 1 moves downward. During the process of assembling the first folded edge 13 of the heat exchanger side plate 1 into the limiting slide groove 211 of the motor cover 21, the guide portion 1141 plays a guiding role, making assembly easier.

[0054] In some exemplary embodiments, Figure 2 , Figure 6 and Fig.12 As shown, the guide portion 1141 includes a step portion 11411 formed by bending the first portion 114 toward the side where the first folded edge 13 is located.

[0055] The first part 114 is bent toward the side where the first folded edge 13 is located (the side away from the heat exchanger body 3) to form a step portion 11411, so that the step portion 11411 is away from the heat exchanger body 3. During assembly, as the heat exchanger side plate 1 moves downward, the step portion 11411 enters the limiting slide groove 211, and the step portion 11411 can gradually abut against the inner wall surface 2112 of the limiting slide groove 211 to guide the first part 114 of the side plate body 11 to gradually slide into the limiting slide groove 211. The step portion 11411 enables the first folded edge 13 of the heat exchanger side plate 1 to be accurately positioned and smoothly enter the limiting slide groove 211, thereby making it easier to guide the first folded edge 13 of the heat exchanger side plate 1 to be assembled into the limiting slide groove 211 of the motor cover 21.

[0056] If the step portion 11411 is not provided, during the assembly of the heat exchanger, it is difficult for the first folded edge 13 of the heat exchanger side plate 1 to align with the limiting slide groove 211 of the motor cover 2, resulting in difficulty in assembly. In the embodiment of the present application, the step portion 11411 is provided to improve assembly efficiency, ensure assembly accuracy, and reduce possible scratches and other damages to the heat exchanger side plate 1 and the motor cover 21 during assembly. In addition, the provision of the step portion 11411 (guide portion 1141) reduces the width of the flange 14, which can reduce the contact area between the flange 14 and the limiting slide groove 211 of the motor cover 21, thereby reducing friction.

[0057] In some exemplary embodiments, Figure 1 , Figure 3-Figure 4 , Figure 6 and Fig.11 As shown, the grounding portion 12 includes a second folded edge 123 disposed on the other side (eg, upper side) of the side plate body 11 , and the second folded edge 123 and the first folded edge 13 are bent in opposite directions.

[0058] The second folded edge 123 may be disposed on a side (e.g., an upper side) of the side plate body 11 away from the motor cover 21, and extend from the side toward the heat exchanger body 3. The second folded edge 123 may be fixed to the heat exchanger body 3 (e.g., fixed by screws). The second folded edge 123 is provided with at least one corresponding limiting portion 122 and fixing portion 121 as described above, for positioning and fixing the ground wire 4.

[0059] In some exemplary embodiments, Figure 9-11 and Fig.13 As shown, the side plate body 11 includes a first side plate body 111, a second side plate body 112 and a third side plate body 113 connected in sequence. The first side plate body 111, the second side plate body 112 and the third side plate body 113 can be connected in a curved shape, that is, the side plate body 11 as a whole can be curved, such as: the side plate body 11 as a whole can be a semi-circular shape with an open lower end.

[0060] The first folded edge 13 is connected to the first side plate body 111, and the first folded edge 13 can be arranged at the lower side of the first side plate body 111, so that the first folded edge 13 is close to the motor cover 21, so as to cooperate with the limiting slide groove 211 of the motor cover 21. The grounding portion 12 is connected to the second side plate body 112, and the grounding portion 12 can be arranged on the upper side of the second side plate body 112, so that the grounding portion 12 is fixed to the upper part of the heat exchanger body 3, so that the ground wire 4 is obliquely wired from top to bottom, thereby guiding the condensed water into the water receiving tray.

[0061] In some exemplary embodiments, the first folded edge 13 and the first side plate body 111 may be an integral structure, and the grounding portion 12 and the second side plate body 112 may be an integral structure.

[0062] like Figure 7-Figure 10 As shown, the embodiment of the present application further discloses an air conditioner indoor unit 100, including a heat exchanger, the heat exchanger including a heat exchanger body 3 and a heat exchanger side plate 1 described in any of the above embodiments, the heat exchanger side plate 1 being installed at an end (e.g., left end or right end) of the heat exchanger body. The heat exchanger may be an evaporator of the air conditioner indoor unit 100. The heat exchanger side plate 1 may be used to fix or limit the heat exchanger body 3.

[0063] In some exemplary embodiments, Figure 9-13 As shown, the air conditioner indoor unit 100 further includes a motor assembly 2, the motor assembly 2 includes a motor cover 21, the motor cover 21 includes a limiting slide groove 211, and the limiting slide groove 211 can cooperate with the first folded edge 13 of the heat exchanger side plate 1 to limit the movement of the heat exchanger relative to the motor cover 21. The inner side wall surface 2112 of the limiting slide groove 211 can cooperate with the guide portion 1141 of the heat exchanger side plate 1 to guide the first folded edge 13 to cooperate with the limiting slide groove 211, thereby making the assembly of the heat exchanger side plate 1 easier.
