[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0048] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installing, connecting, assembling, and matching should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model based on the specific content of the technical solution.

[0049] The multi-split air conditioning system integrates three functions: cooling, heating and hot water, i.e. cooling in summer, heating and domestic hot water in winter. When heating in winter, in addition to sending hot air to the room through the indoor unit, the water in the floor heating pipe is heated by the hydraulic module to heat the room from the ground.

[0050] Reference Figure 1 As shown, the hydraulic module is generally installed on the wall by hanging. When the outdoor machine heats up, the refrigerant in the hydraulic module exchanges heat with the water in the floor heating pipe, transferring the heat of the refrigerant to the water, and the floor heating pipe can heat up the room from the ground. The hydraulic module includes an electric control box. In order to facilitate wiring during production and later maintenance, the existing electric control box is generally installed flat in the shell of the hydraulic module, that is, the circuit board in the electric control box is parallel to the front panel of the shell, and the side of the circuit board with electrical components installed faces the front panel.

[0051] It is easy to understand that the thickness of the circuit board is much smaller than the width and length of the circuit board, and correspondingly, the thickness of the electric control box is also smaller than the width and length of the electric control box. When the electric control box is installed flat in the shell of the hydraulic module, the height space occupied by the electric control box in the shell is large, resulting in a large overall height dimension of the hydraulic module, which cannot meet the design requirements of the miniaturized structure.

[0052] For this purpose, refer to Figures 2 to 11 As shown, the first embodiment of the utility model provides a hydraulic module, which can be used in a multi-connected air-conditioning system of natural fluorine and ground water to supply hot water to the floor heating pipes. The hydraulic module can also be used for water heaters, circulating water-heated towel racks, etc.

[0053] Reference Figure 2As shown, it can be understood that the hydraulic module includes a shell 400, a heat exchange assembly and an electric control box assembly, wherein the shell 400 is connected by a panel, a top cover 430, a back plate 440 and a plurality of side plates, wherein the panel is detachably connected to the front side of the shell 400, the top cover 430 is detachably connected to the top of the shell 400, and an inner cavity 410 is defined between the panel, the top cover 430, the back plate 440 and the plurality of side plates. The shell 400 is generally a rectangular parallelepiped structure, and the long side of the shell 400 is arranged in the up-down direction, that is, the long side direction of the shell 400 is the height direction of the shell 400.

[0054] Reference Figure 3 and Figure 4 As shown, it can be understood that the heat exchange assembly and the electric control box assembly are both installed in the inner cavity 410, wherein the heat exchange assembly includes a heat exchanger 450, and of course, the heat exchange assembly also includes an expansion tank 460, etc. The heat exchanger 450 is a heat exchange tube structure arranged in a spiral, and a surrounding space is formed at the center of the heat exchange tube structure. In order to save the installation space inside the shell 400, the expansion tank 460 and other components are arranged in the surrounding space. It is easy to understand that at least a water pump, a drain valve, a water flow switch, etc. are also installed in the inner cavity 410, and the above-mentioned water pump, drain valve, water flow switch, etc. are all installed below the heat exchange assembly. Therefore, the installation space of the electric control box assembly is reserved at the top of the heat exchanger 450. That is to say, the electric control box assembly and the heat exchange assembly are arranged side by side in the height direction of the shell 400, and the electric control box assembly is located above the heat exchange assembly.

[0055] Of course, it is understandable that the electric control box assembly can also be arranged below the heat exchange assembly. In this case, the hydraulic module can take in or out water from the left and right sides.

[0056] It is understandable that by removing the panel, the components in the shell 400 can be easily repaired or replaced. In addition, some later maintenance operations also require the removal of the top cover 430. In order to avoid the situation where the top space of the shell 400 is small and the top cover 430 cannot be removed from the top of the shell 400, the connection method between the top cover 430 and the side panel is set to an internal connection method, that is, the fasteners between the top cover 430 and the side panel are located in the inner cavity 410, and the fasteners can be locked or loosened by operating the fasteners in the inner cavity 410. The fasteners can be screws or buckles, etc., so as to fix or remove the top cover 430. Therefore, during later maintenance, after removing the panel, the top cover 430 can be directly removed from the inner cavity 410, which is convenient for operation.

[0057] Reference Figure 4 and Figure 5As shown, it can be understood that the electric control box assembly includes a base 100, an electric control box body 200 and an electric control board 260, wherein the base 100 includes two first connecting members 110 arranged at intervals, and an accommodating space 120 is defined between the two first connecting members 110, and the electric control box body 200 is installed in the accommodating space 120.

[0058] Reference Figure 4 and Figure 5 As shown, it can be understood that, generally speaking, the electric control box body 200 is a plastic part, and the electric control board 260 is fixedly installed in the electric control box body 200. The electric control box body 200 and the electric control board 260 have the same thickness direction, the same length direction, and the same width direction. Since the thickness of the electric control board 260 is much smaller than its own length and width, the thickness of the electric control box body 200 is also smaller than its own length and width.

[0059] Reference Figure 5 As shown, it is easy to understand that, in order to make the wiring neat, the outer periphery of the electric control box body 200 is provided with a wire groove 240, for example, the wire groove 240 is provided on two adjacent side walls of the electric control box body 200, and the electric control box body 200 is also provided with a plurality of buckle parts 250, and the plurality of buckle parts 250 are arranged at intervals along the length direction of the wire groove 240. Therefore, the wire harness of the electric control board 260 can be accommodated in the wire groove 240, and the wire harness can be clamped by the plurality of buckle parts 250, so as to avoid the wire harness being arranged in a disorderly manner and reduce the risk of the wire harness being torn off.

[0060] Reference Figure 4 As shown, it can be understood that the electric control box body 200 is slidably mounted on the two first connecting members 110. Specifically, the sliding direction of the electric control box body 200 is perpendicular to the thickness direction of the electric control box body 200, that is, the sliding direction of the electric control box body 200 is parallel to the electric control board 260. The left and right sides of the electric control box body 200 are respectively provided with second connecting members 210, and the two second connecting members 210 are respectively slidably matched with the two first connecting members 110, so that the electric control box body 200 can slide relative to the base 100. The first connecting member 110 and the second connecting member 210 can be a combination of a slide rail and a slider, that is, the first connecting member 110 is a slide rail, and the second connecting member 210 is a slider; or a combination of a guide rod and a guide sleeve, that is, the first connecting member 110 is a guide rod, and the second connecting member 210 is a guide sleeve; or a combination of a slide groove and a slider, that is, the first connecting member 110 is provided with a slide groove, and the second connecting member 210 is a slider, etc., as long as they can slide relative to each other.

[0061] Reference Figure 2As shown, the base 100 is fixedly connected to the shell 400. The base 100 and the shell 400 can be directly welded, connected by screws or clamped, etc. Therefore, the electric control box body 200 can slide relative to the shell 400. Since the electric control board 260 is fixedly installed on the electric control box body 200, the electric control board 260 and the electric control box body 200 can move synchronously. At the same time, the electric control box body 200 slides in the front-to-back direction, that is, at this time, the thickness direction of the electric control box body 200 and the thickness direction of the electric control board 260 are parallel to the up-down direction, the up-down direction is the height direction of the shell 400, that is, the height direction of the electric control board 260 is perpendicular to the shell 400. At this time, one side of the electric control board 260 along the thickness direction faces the heat exchange component. Therefore, when assembling the hydraulic module, when the panel is not installed, or during later maintenance, after the panel is removed, the electrical control box body 200 can be directly slid forward and pulled out relative to the shell 400, so that the electrical control box body 200 extends out of the inner cavity 410, and the electrical control board 260 is moved out of the inner cavity 410 along with the electrical control box body 200, so that the electrical control board 260 can be conveniently connected to the wiring during assembly, and the electrical control board 260 can be conveniently repaired or electrical components can be replaced during later maintenance, which is easy to operate.

[0062] At the same time, since the electric control box assembly and the heat exchange assembly are arranged side by side in the height direction of the shell, and the thickness directions of the electric control box body 200 and the electric control board 260 are parallel to the height direction of the shell 400, and since the thickness of the electric control box body 200 is the smallest among the thickness, length and width, the height space occupied by the electric control box body 200 in the shell 400 is the smallest, thereby reducing the height space occupied by the electric control box assembly in the shell 400, thereby reducing the overall height of the hydraulic module, reducing the overall height by about 160 mm, and meeting the design requirements of the miniaturized structure of the hydraulic module.

[0063] It is understandable that in other embodiments, the angle between the electric control board 260 and the panel can be an acute angle, that is, the electric control board 260 is arranged obliquely relative to the height direction of the housing 400. At this time, the sliding direction of the electric control board 260 and the electric control box body 200 can be obliquely upward or obliquely downward. At this time, the height space occupied by the electric control box body 200 in the housing 400 is smaller than the height space occupied when the electric control box is placed flat, which can also reduce the overall height of the hydraulic module and meet the design requirements of the miniaturized structure of the hydraulic module. In addition, the electric control box body 200 and the electric control board 260 can be slidably pulled out to move the electric control board 260 out of the inner cavity 410 for easy wiring or later maintenance.

[0064] It can be understood that the electrical components in the electrical control board 260 are usually located on one side along the thickness direction of the electrical control board 260. When the electrical control box assembly is placed in the inner cavity 410, the side of the electrical control board 260 where the electrical components are arranged faces downward, which can effectively prevent dust from accumulating on the electrical components and causing short circuits and burning of the electrical control board 260.

[0065] Reference Figure 4 and Figure 6 As shown, it can be understood that the two first connecting members 110 are respectively located on the left and right sides of the base 100. In order to make the first connecting member 110 and the electric control box body 200 slide and cooperate, the first connecting member 110 is provided with a guide groove 113, which is arranged along the front-to-back direction, that is, the guiding direction of the guide groove 113 is parallel to the front-to-back direction, and the guide groove 113 penetrates along the left-to-right direction. Specifically, in the cross section perpendicular to the guiding direction of the guide groove 113, the cross section of the first connecting member 110 is roughly U-shaped, that is, the first connecting member 110 includes a first plate 111 and a second plate 112 located on the left and right sides, the two first plates 111 are located on the opposite sides of the two first connecting members 110, and the two second plates 112 are located on the back sides of the two first connecting members 110, and the guide groove 113 is provided on the first plate 111. Correspondingly, the second connecting member 210 is provided as a rotating shaft, which is provided at the rear end of the electric control box body 200 and arranged along the left-to-right direction, and the two ends of the rotating shaft protrude from the electric control box body 200 respectively. The two ends of the rotating shaft are respectively inserted into the two guide grooves 113, and the rotating shaft can slide along the guide grooves 113, so that the electric control box body 200 can slide in the front-to-back direction relative to the base 100, so as to connect or maintain the electric control board 260. At the same time, after the electric control box body 200 slides along the guide grooves 113 and extends out of the inner cavity 410, the electric control box body 200 can be rotated around the rotating shaft to adjust the direction of the electric control board 260, so as to facilitate wiring or maintenance.

[0066] Reference Figure 7 As shown, for example, when assembling the hydraulic module, the shell 400 is usually tilted and arranged, and the panel is usually facing upward. Therefore, after the electrical control box body 200 is pulled upward, the electrical control box body 200 is flipped backward 90° so that the side of the electrical control panel 260 with electrical components is facing upward, which is convenient for workers to connect wires.

[0067] Reference Figure 8 As shown, or when the hydraulic module is installed at the user end and needs maintenance, the housing 400 is usually placed forward with the panel facing the front. Therefore, after the electric control box body 200 is pulled forward, the electric control box body 200 is flipped upward to expose the side of the electric control board 260 with electrical components, which is convenient for maintenance personnel to perform maintenance operations on the electric control board 260. Since the housing 400 has a top cover 430, the top cover 430 hinders the electric control box body 200, which will cause the electric control box body 200 to be unable to flip upward 90°. Therefore, it is usually sufficient to flip the electric control box body 200 upward about 65°.

[0068] Reference Figure 5As shown, it is easy to understand that since the end of the rotating shaft is only passed through the guide groove 113 on the first plate 111, the second plate 112 has a shielding effect on the end of the rotating shaft, which can prevent the end of the rotating shaft from being exposed. On the one hand, it makes the integrity of the electric control box assembly better and more beautiful, and on the other hand, it can prevent the end of the rotating shaft from protruding from the first connecting member 110 and scratching the workers.

[0069] Reference Figure 4 and Figure 6 As shown, it can be understood that the two ends of the rotating shaft are respectively provided with a limiting portion 220, the limiting portion 220 is circular, and the outer diameter of the limiting portion 220 is greater than the maximum groove width of the guide groove 113, that is, the minimum outer diameter of the limiting portion 220 is greater than the maximum groove width of the guide groove 113. The limiting portion 220 is located between the first plate 111 and the second plate 112, that is, the limiting portion 220 is located on the two opposite sides of the two first plates 111. Therefore, when the electric control box body 200 is slid along the first connecting member 110, the two limiting portions 220 can prevent the rotating shaft from being separated from the guide groove 113 and causing the guide failure problem, thereby improving the sliding stability and reliability of the electric control box body 200.

[0070] Reference Figure 6 As shown, it is easy to understand that the outer diameter of the shaft is defined as D 1 , the outer diameter of the limiting portion 220 is D 2 , the maximum width of the guide groove 113 is W 1 , satisfied: D 1 <W 1 <D 2 .

[0071] Reference Figure 4 and Figure 6 As shown, it can be understood that, in order to enable the two limiting portions 220 to be placed on the two opposite sides of the two first plates 111, the first connecting member 110 is provided with an installation opening 114, which is provided on the first plate 111 and is approximately located in the middle of the guide groove 113 along the guide direction, and the installation opening 114 is located at the lower side of the guide groove 113 and communicates with the guide groove 113, and the limiting portion 220 can pass through the installation opening 114, that is, the limiting portion 220 can pass through the first plate 111 at the installation opening 114. Along the guide direction of the guide groove 113, the width of the installation opening 114 is defined as W 2 , satisfying W 2 >D 2 Therefore, by passing the end of the rotating shaft and the limiting part 220 through the first plate 111 at the installation opening 114, and moving the rotating shaft into the guide groove 113, the electric control box body 200 can be slidably installed on the first connecting member 110, and the installation operation is convenient, and the connection structure is simple and reliable. When disassembling, the end of the rotating shaft and the limiting part 220 can be taken out at the installation opening 114, so that the electric control box body 200 and the electric control board 260 therein can be taken out separately for maintenance, without the need for disassembly tools, and the operation is convenient.

[0072] It is easy to understand that the limiting portion 220 and the rotating shaft can be configured to be threadedly connected, and after the rotating shaft is inserted into the guide groove 113, the limiting portion 220 can be screwed onto the end of the rotating shaft.

[0073] Reference Figure 6 and Figure 7 As shown, it can be understood that, along the guiding direction of the guide groove 113, the guide groove 113 is defined to include a first groove section 1131 located at the rear end, and a second groove section 1132 located at the front end. It is easy to understand that when the rotating shaft moves to the first groove section 1131, the electric control box body 200 is completely accommodated in the accommodating space 120, and when the rotating shaft slides along the guide groove 113 to the second groove section 1132, the electric control box body 200 extends out of the inner cavity 410 and is located at the extreme position. Generally speaking, except for the first groove section 1131, the groove width of the remaining groove sections of the guide groove 113 is consistent and greater than the outer diameter of the rotating shaft, so that the rotating shaft can slide smoothly along the guide groove 113. From the direction from the second groove section 1132 to the first groove section 1131, that is, from the front to the back, the groove width at the first groove section 1131 decreases until the groove width is equal to the outer diameter of the rotating shaft. Therefore, when installing the electric control box body 200 into the accommodating space 120, the electric control box body 200 is moved backward until the rotating shaft is clamped between the two opposite groove walls at the first groove section 1131. At this time, under the action of friction, the electric control box body 200 and the first connecting member 110 can be relatively fixed, thereby improving the installation stability of the electric control box body 200 and preventing looseness. When maintenance is required, the electric control box body 200 can be pulled out forward with force, which is convenient to operate.

[0074] Reference Figure 4 and Figure 6 As shown, it can be understood that the base 100 includes a first side plate 130, the first side plate 130 is connected between the two first connecting members 110 and is located on the upper side of the first connecting members 110, and the first side plate 130 is provided with two card slots 131, the two card slots 131 are arranged at intervals along the left and right directions, and the card slots 131 are slot hole structures. Correspondingly, the upper wall of the electric control box body 200 is provided with a card connection portion 230 corresponding to the card slots 131 one by one, and the card connection portion 230 is a plug-in block structure protruding from the upper wall of the electric control box body 200. When the electric control box body 200 is completely accommodated in the accommodating space 120, that is, when the rotating shaft moves to the first slot section 1131, the card connection portion 230 is penetrated in the card slot 131 and plugged into the first side plate 130, which can also be understood as the card connection portion 230 and the card slot 131 are card-engaged. Therefore, the installation stability of the electric control box body 200 can be further improved, and at the clamping portion 230, the first side plate 130 can provide an upward supporting force for the electric control box body 200 to prevent the electric control box body 200 from flipping downward, thereby improving the installation stability.

[0075] Reference Figure 4 and Figure 6 As shown, it can be understood that the base 100 also includes two baffles 140, which are respectively arranged at the front end of the first connecting member 110, and the baffles 140 are located at the lower side of the first connecting member 110, that is, the first side plate 130 and the baffle 140 are respectively located at the upper and lower sides of the accommodating space 120. When the electric control box body 200 is completely accommodated in the accommodating space 120, that is, when the rotating shaft moves to the first slot section 1131, the two baffles 140 are both in contact with the lower side wall of the electric control box body 200, so that the two baffles 140 can provide an upward supporting force to the front end of the electric control box body 200, so as to support the electric control box body 200, prevent the electric control box body 200 from turning downward, and further improve the installation stability. In order to ensure that the baffle 140 can stably support the electric control box body 200, the distance that the baffle 140 extends forward from the end of the first connecting member 110 is not less than 3 mm.

[0076] Reference Figure 4 and Figure 6 As shown, it can be understood that the first connecting member 110 is further provided with an auxiliary groove 115, the auxiliary groove 115 is located at the second groove section 1132 of the guide groove 113 and communicates with the guide groove 113, the auxiliary groove 115 is located on the upper side of the guide groove 113, and the groove width of the auxiliary groove 115 is greater than the outer diameter of the rotating shaft. Specifically, the auxiliary groove 115 includes a third groove section 1151 and a fourth groove section 1152, one end of the third groove section 1151 is connected to the second groove section 1132 and extends upward, and the fourth groove section 1152 is connected to the other end of the third groove section 1151 and extends toward the first groove section 1131, that is, the fourth groove section 1152 extends backward, and the fourth groove section 1152 is perpendicular to the third groove section 1151, that is, the auxiliary groove 115 is L-shaped, and the auxiliary groove 115 and the guide groove 113 are combined to form a U-shape with an opening facing backward. Therefore, when the electric control box body 200 slides out of the inner cavity 410 and the rotating shaft moves to the second slot section 1132, the rotating shaft can be further moved along the auxiliary slot 115 until the rotating shaft moves to the fourth slot section 1152, and then the electric control box body 200 can be flipped around the rotating shaft to facilitate wiring or maintenance. Or, in the process of the rotating shaft moving from the second slot section 1132 to the fourth slot section 1152, the electric control box body 200 is flipped at the same time. Since the rotating shaft is located at the fourth slot section 1152 at this time, in the process of flipping the electric control box body 200, the rotating shaft can be prevented from moving along the guide slot 113 toward the first slot section 1131, so that the electric control box body 200 is always located on the side close to the second slot section 1132 after flipping, and the electric control box body 200 is stably placed, which is convenient for workers to connect wires or maintenance personnel to perform later maintenance.

[0077] Reference Figure 6 As shown, it is easy to understand that the length of the third slot section 1151 is defined as L 1 , the length of the fourth slot section 1152 is L 2 , satisfying: L 1≥D 2 , L 2 ≥L 1 , so that the fourth groove section 1152 deviates from the guide groove 113 by a greater distance, which can prevent the rotating shaft from easily moving back into the guide groove 113 during the process of flipping the electric control box body 200.

[0078] Reference Figures 6 to 8 As shown, it can be understood that the auxiliary groove 115 also includes a recess 1153, which is arranged at the groove wall of the fourth groove section 1152, and the recess 1153 is located on the side of the fourth groove section 1152 close to the guide groove 113 and is recessed toward the guide groove 113, that is, the recess 1153 is located at the lower side of the fourth groove section 1152, and the recess 1153 can accommodate at least part of the rotating shaft. During later maintenance, the electric control box body 200 is pulled out to move the rotating shaft to the fourth groove section 1152, and the electric control box body 200 is turned upward, and the rotating shaft can move into the recess 1153 under the action of weight. During the process of flipping the electric control box body 200 or after flipping the electric control box body 200, the recess 1153 can limit the movement of the rotating shaft from the fourth slot section 1152 to the third slot section 1151, or even to the guide slot 113, so that the flipped electric control box body 200 can be placed more stably, avoiding the electric control box body 200 from moving at will, thereby facilitating maintenance by maintenance personnel.

[0079] Reference Figure 6 As shown, it is easy to understand that the concave position 1153 is semicircular, and the radius of the concave position 1153 is R, which satisfies: D 1 <2R<D 2 Therefore, the rotating shaft can be stably accommodated in the recess 1153 to prevent the rotating shaft from deviating and affecting the flipping of the electric control box body 200 , and the rotating shaft can be prevented from being separated from the first connecting member 110 .

[0080] Reference Figure 6 As shown, it can be understood that the base 100 also includes a second side panel 150, which is connected between the two first connecting members 110 and is located on the upper side of the first connecting members 110. It is easy to understand that the left end of the second side panel 150 is also connected to the right end of the first side panel 130 through a transition plate, and the right end of the second side panel 150 is located on the left side of the fourth slot section 1152.

[0081] Reference Figure 7 As shown, therefore, during the assembly process, when the top cover 430 is not installed, after the electric control box body 200 is pulled out and flipped 90°, the electric control box body 200 abuts against the second side plate 150, and the second side plate 150 provides an upward supporting force to the electric control box body 200, thereby supporting the electric control box body 200, preventing the electric control box body 200 from further flipping over, and keeping the electric control box body 200 stable for workers to connect wires.

[0082] It is easy to understand that when the hydraulic module is installed at the user end and needs maintenance, due to the existence of the top cover 430 , after the electric control box body 200 is pulled out and turned over, the electric control box body 200 abuts against the top cover 430 .

[0083] Reference Figure 6 and Figure 7 As shown, it can be understood that a flange structure 151 is provided at one end of the second side plate 150 away from the first side plate 130, and the flange structure 151 extends toward the side away from the accommodating space 120, that is, the flange structure 151 extends toward the thickness direction of the second side plate 150. Therefore, when the electric control box body 200 abuts against the second side plate 150, the flange structure 151 contacts the electric control box body 200, which can increase the contact area, that is, increase the support area, so that the electric control box body 200 is placed more stably.

[0084] Reference Fig.10 As shown, it can be understood that the electric control box assembly further includes a box cover 300, the opening of the box cover 300 faces backward, the box cover 300 is covered on the periphery of the base 100 and the electric control box body 200, and the box cover 300 is connected to the front end of the electric control box body 200 by screws. In order to further improve the installation stability of the box cover 300, the box cover 300 is connected to the bottom shell. Therefore, the electric control box body 200 can be wrapped by the box cover 300, that is, the box cover 300 also wraps the electric control board 260, so as to prevent dust or other foreign matter from falling onto the electric control board 260, prevent short circuit or damage to the electric control board 260, effectively extend the service life of the electric control board 260 and improve reliability.

[0085] Reference Fig.11 As shown, it can be understood that two wire outlets 330 are provided at the rear end of the box cover 300 to lead out the wire harness of the electric control board 260 and connect it with other components in the housing 400.

[0086] Reference Fig. 9 As shown, it can be understood that a bracket 420 is installed in the housing 400, the bracket 420 is U-shaped and has an opening facing the rear side, and the bracket 420 is welded and fixed to the housing 400. A hanging ear 160 is provided at the left end of the base 100, and the hanging ear 160 is provided with a slot 161, and the slot 161 is downward. The slot width of the slot 161 is defined as W 3 , the depth of slot 161 is D 3 , the thickness of the bracket 420 is T, which satisfies: W 3 ≥T, that is, the slot width of the slot 161 is greater than or equal to the thickness of the bracket 420, so that the bracket 420 can be inserted into the slot 161; D 3≥3mm, which can ensure the reliability of the ear 160. When installing the electric control box assembly, the ear 160 of the base 100 is hung on the bracket 420, the bracket 420 is inserted into the slot 161, and the left and right ends of the base 100 are fixed to the bracket 420 through the first fastener 170. The first fastener 170 can be a screw, so that the base 100 is firmly installed on the bracket 420. It is easy to understand that since the ear 160 is hung and matched with the bracket 420, during the installation of the base 100, the base 100 can be hung on the bracket 420 first, and the bracket 420 will not fall off, and then the base 100 can be fixed by the first fastener 170, which is convenient for positioning and tightening the first fastener 170, reducing the difficulty of installation. And during the disassembly process, after loosening the first fastener 170, the base 100 will not fall off, and the safety is good. In addition, since the hanging ear 160 is hung on the bracket 420 , the hanging ear 160 can reduce the force borne by the first fastener 170 , effectively prolonging the service life and improving the installation stability of the base 100 .

[0087] Reference Fig. 9 As shown, it can be understood that, from the bottom wall of the slot 161 toward the slot opening of the slot 161, the width of the slot section of the slot 161 near the slot opening increases gradually, forming a V-shaped slot section, and the angle between the two slot walls at the slot section is about 45°. Therefore, in the process of hanging the ear 160 on the bracket 420, it is easy to quickly insert the bracket 420 into the slot 161 without precise alignment, reducing the difficulty of installation and improving the installation efficiency.

[0088] Reference Figure 2 , Figure 3 and Fig.10 As shown, it can be understood that the end of the box cover 300 facing the base 100 is provided with a hook 310, and the box cover 300 can be hung on the bracket 420 through the hook 310, which is convenient for installation. At the same time, the box cover 300 is also fastened to the bracket 420 through the second fastener 320, and the second fastener 320 here can be a screw to improve the stability of the connection. Specifically, the hook 310 protrudes backward from the box cover 300, and the end of the hook 310 is provided with a hook portion 311, and the hook portion 311 can be located on the upper side or the lower side, that is, the hook 310 can be arranged upward or downward, and correspondingly, the bracket 420 is provided with a positioning groove 421, and the hook 310 is penetrated in the positioning groove 421, so as to realize the positioning of the box cover 300, and then the box cover 300 is fixedly connected to the bracket 420 through the second fastener 320, so that it is convenient to position and tighten the second fastener 320, and reduce the difficulty of installation.

[0089] It is understandable that the box cover 300 is also connected to the electric control box body 200 by screws to further improve the connection stability of the box cover 300.

[0090] Reference Figure 3 and Fig.10 As shown, it can be understood that along the up and down direction, the width of the positioning groove 421 is defined as W 4 , the width of the hook 310 is W 5 , satisfying: W 4 =W 5 +3T, that is, the width of the positioning groove 421 is three times greater than the width of the hook 310 and the thickness of the bracket 420, so that the hook 310 can be inserted into the positioning groove 421, reducing the difficulty of installation. At the same time, it is easy to understand that after the second fastener 320 is locked, the hook 311 and the positioning groove 421 are staggered, that is, the hook 311 and the positioning groove 421 do not correspond, so that the hook 310 can be buckled with the bracket 420, preventing the box cover 300 from falling off, and improving the installation stability of the box cover 300.

[0091] It is easy to understand that the base 100 and the box cover 300 are both detachably connected to the bracket 420, so the electric control box assembly can be removed from the housing 400 as a whole for easy maintenance.
