Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular, to an electric control box and an air conditioner. Background Technique

[0002] In a wall-mounted air conditioner indoor unit, the electric control box is usually arranged at the end of the internal space of the wall-mounted air conditioner indoor unit, such as the left end or the right end. However, with such an arrangement, the overall length of the wall-mounted air conditioner indoor unit will increase. On the one hand, it will lead to an increase in the materials used for the base, middle frame and panel of the air conditioner, increasing the cost of the air conditioner. On the other hand, it will also result in a larger length of the air conditioner, making it not easy to install in the indoor space.

[0003] Generally, a display area is arranged on the panel of the wall-mounted air conditioner indoor unit, and a display component is arranged behind the display area to display information such as the set temperature and the operating mode of the air conditioner. The display component is installed on the inner surface of the panel and faces the display area. If the display component is directly integrated into the electric control box, since the position of the electric control box is fixed, there may be a gap between the front surface of the display component and the panel, resulting in blurred display content. Summary of the Utility Model

[0004] The purpose of the first aspect of the utility model is to provide an electric control box to solve the technical problem of blurred display information of the existing wall-mounted air conditioner indoor unit.

[0005] The electric control box provided by the first aspect of the utility model includes a box body, a display component and a circuit board installed on the box body. The box body has a first hollow part. The display component includes a floating part, a floating driving part and a first display lamp fixedly connected to the circuit board. At least a part of the floating part is located outside the first hollow part. The floating driving part is respectively connected to the floating part and the circuit board, and the floating driving part is configured to be able to drive the floating part away from the circuit board and to be able to allow the floating part to approach the circuit board.

[0006] The beneficial effects brought by the electric control box of the utility model are as follows:

[0007] By arranging a floating part in the display component and using the floating driving part to drive the floating part away from the circuit board and to be able to allow the floating part to approach the circuit board, when there is an installation error between the box body of the electric control box and the panel of the wall-mounted air conditioner indoor unit, the surface of the floating part can be attached to the inner side surface of the panel to clearly display relevant information, avoiding blurred display information. Moreover, at least a part of the floating part is located outside the first hollow part, which can also ensure that it is the floating part rather than the front surface of the box body that is attached to the panel, preventing the front surface of the box body from lifting the floating part and causing blurred display information.

[0008] In an alternative technical solution, the display component includes a fixing member fixedly mounted on the circuit board. The fixing member is provided with a first guiding portion, and the floating member is provided with a second guiding portion. The fixing member and the floating member can slide relative to each other through the cooperation of the first guiding portion and the second guiding portion.

[0009] By providing a fixing member fixedly mounted on the circuit board, and providing a first guiding portion thereon, which cooperates with the second guiding portion provided on the floating member to achieve the relative sliding of the fixing member and the floating member, the stability of the movement of the floating member can be improved to ensure the position accuracy of the displayed information.

[0010] In an alternative technical solution, the fixing member is provided with a second hollow portion, and the floating member is provided with a third hollow portion. The third hollow portion, the second guiding portion surrounding the third hollow portion, the second hollow portion, and the first display lamp are correspondingly arranged. At least a part of the second guiding portion is continuously arranged around the corresponding third hollow portion, and the second guiding portion extends from the floating member towards the circuit board.

[0011] By providing a third hollow portion on the floating member, and correspondingly providing a second hollow portion and a first display lamp on the fixing member, the illuminated areas can be selectively formed according to the shapes, sizes, and relative positions of the respective third hollow portions, and the arrangement of the illuminated areas can be used to display corresponding information. Moreover, the second guiding portion is continuously arranged around the third hollow portion, which can prevent the third hollow portion from being illuminated by the corresponding first display lamp, thereby improving the accuracy of information display.

[0012] In an alternative technical solution, at least a part of the first guiding portion of the fixing member is continuously arranged around the corresponding second hollow portion, and the first guiding portion extends from the fixing member in a direction away from the circuit board. For the second guiding portion and the first guiding portion, a part of one of them is always sleeved outside the other.

[0013] By providing a second guiding portion on the fixing member to surround the corresponding third hollow portion, the diffusion of light emitted from the first display lamp to the surrounding can be prevented, improving the concentration of light. By keeping a part of one of the first guiding portion and the second guiding portion always sleeved outside the other, it is possible to prevent the light of the first display lamp from leaking out in the direction away from the circuit board. On the one hand, the light intensity of each third hollow portion is increased, and on the other hand, the interference received by other third hollow portions is reduced, thereby improving the display effect.

[0014] In an alternative technical solution, among the fixing member and the floating member, one is provided with a stroke limiting groove, and the other is provided with a stroke limiting portion. The stroke limiting portion can slide in the stroke limiting groove. When the stroke limiting portion abuts against the first side wall of the stroke limiting groove, the distance between the floating member and the circuit board is the farthest.

[0015] By providing a stroke limiting groove and a stroke limiting portion, the maximum distance between the floating member and the circuit board can be restricted, thereby preventing the floating member from falling off the fixing member during the process of installing the circuit board into the electric control box after the display component is installed on the circuit board, and during the process of installing the electric control box onto the wall-mounted air conditioner indoor unit. This setting enables the display component to be first installed on the circuit board and then the circuit board to be installed into the electric control box. Compared with the solution of first installing the circuit board into the box body, on the one hand, during the process of installing the display component on the circuit board, the display component can be effectively held and not affected by the edge of the first hollow portion. On the other hand, the circuit board during the installation of the display component can be placed in a suitable position, so that the position of the direct installation fixing member of the circuit board has better support, preventing damage to the circuit board during the installation process.

[0016] In an alternative technical solution, among the floating member and the fixing member, one is provided with a spring support post, and a compression spring is sleeved on the spring support post. The compression spring abuts against the other of the floating member and the fixing member.

[0017] By providing a spring support post in one of the floating member and the fixing member to sleeve a compression spring and abut against the other, the floating member can be subjected to the acting force of the compression spring, so that the floating member can be closely attached to the back side of the panel of the wall-mounted air conditioner indoor unit, ensuring clear display information.

[0018] In an alternative technical solution, the fixing member is provided with a fixing tongue, and the circuit board is provided with a fixing hole. The fixing tongue is inserted through the fixing hole, and the first anti-retreat portion of the fixing tongue abuts against the rear side of the circuit board.

[0019] By providing a fixing tongue and using the first anti-retreat portion of the fixing tongue to abut against the rear side of the circuit board, after the fixing tongue is inserted into the circuit board, the fixing member can be prevented from detaching from the circuit board to achieve reliable fixation of the fixing member and the circuit board.

[0020] In an alternative technical solution, the fixing member includes a first convex rib and a first plate body portion. The first plate body portion is disposed opposite to the first convex rib and forms a first groove; the box body is provided with a second convex rib at the edge of the first hollow portion, and the second convex rib is matched with the first groove.

[0021] By setting the first plate body part and the first convex rib to form a first groove, and using the second convex rib to match the second groove, a labyrinth seal can be formed by the two to prevent the condensation on the front surface of the box body from flowing into the display component and further flowing onto the circuit board, thereby improving the reliability of the electric control box.

[0022] In an alternative technical solution, the first hollow part is a notch part. The box body includes a box base and a box cover buckled on the box base. The bottom wall of the box base is provided with a first slot, and the bottom of the circuit board is inserted into the first slot; the top wall of the box base is provided with a second slot, and the top of the circuit board is inserted into the second slot; the opening direction of the notch part, the extending directions of the first slot and the second slot are all parallel to the direction in which the box cover is buckled on the box base.

[0023] By providing a first slot on the bottom wall of the box base of the circuit board to insert the bottom of the circuit board, and providing a second slot on the top wall of the box base to insert the top of the circuit board, the upper and lower edges of the circuit board can be positioned, so that the circuit board can maintain its position in the front-rear direction and pitch, thereby improving the installation stiffness of the circuit board. Moreover, making the opening direction of the notch part as the first hollow part and the extending directions of the first slot and the second slot all parallel to the direction in which the box cover is buckled on the box base can install the display component in place at the same time when inserting the circuit board, improving the installation efficiency.

[0024] The purpose of the second aspect of the present invention is to provide an air conditioner to solve the technical problem of blurred display information of the wall-mounted air conditioner indoor unit.

[0025] The air conditioner provided by the second aspect of the present invention includes a wall-mounted air conditioner indoor unit, and the wall-mounted air conditioner indoor unit includes a base, a wind wheel motor and the electric control box of any one of the above. The wind wheel motor is installed on the base, and the electric control box is located in front of the wind wheel motor.

[0026] By providing the above electric control box in the air conditioner, correspondingly, the air conditioner has all the advantages of the above electric control box, which will not be elaborated here one by one. Description of the Drawings

[0056] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following specifically describes the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0057] Embodiment 1:

[0058] Figure 1 It is a schematic structural diagram of the electronic control box provided in Embodiment 1 of the present utility model; Figure 2 It is a three-dimensional cross-sectional view of the electronic control box provided in Embodiment 1 of the present utility model applied to a wall-mounted air conditioner indoor unit; Figure 3 It is a schematic structural diagram of the separation of the box cover in the electronic control box provided in Embodiment 1 of the present utility model; Figure 4 It is a three-dimensional disassembled view of the electronic control box provided in Embodiment 1 of the present utility model; Figure 5 It is a schematic structural diagram of the box base in the electronic control box provided in Embodiment 1 of the present utility model; As Figures 1-5 shown, the electronic control box provided in Embodiment 1 of the present utility model includes a box body 100, a display component, and a circuit board 400 installed on the box body 100. The box body 100 has a first hollow portion 111. The display component includes a floating member 200, a floating driving member, and a first display lamp 410 fixedly connected to the circuit board 400. At least a part of the floating member 200 is located outside the first hollow portion 111; the floating driving member is respectively connected to the floating member 200 and the circuit board 400, and the floating driving member is configured to be able to drive the floating member 200 away from the circuit board 400 and to allow the floating member 200 to approach the circuit board 400.

[0059] By arranging a floating member 200 in the display component and using a floating driving member to drive the floating member 200 away from the circuit board 400 and allowing the floating member 200 to approach the circuit board 400, when there is an installation error between the box body 100 of the electric control box and the panel 650 of the wall-mounted air conditioner indoor unit, the surface of the floating member 200 can be attached to the inner side surface of the panel 650, so as to clearly display relevant information and avoid blurred display information. Moreover, at least a part of the floating member 200 is located outside the first hollow portion 111, which can also ensure that it is the floating member 200 rather than the front surface of the box body 100 that is attached to the panel 650, preventing the front surface of the box body 100 from lifting the floating member 200 and causing blurred display information.

[0060] In this embodiment, the case where the electric control box is located at the right end of the wall-mounted air conditioner indoor unit is taken as an example for introduction, that is, the wind wheel motor 630 is located at a position close to the right end on the base 610, the wind wheel 620 driven by the wind wheel motor 630 is located on the left side of the wind wheel motor 630, and a motor gland 640 is provided outside the wind wheel motor 630. In this embodiment, the box body 100 of the electric control box includes a box seat 110 and a box cover 120, and the circuit board 400 is mainly arranged in the box seat 110. Since the electric control box is located in the right part of the internal space of the wall-mounted air conditioner indoor unit, the box cover 120 is buckled on the box seat 110 from right to left.

[0061] Among them, in this embodiment, a part of the floating member 200 is located outside the first hollow portion 111, and the floating member 200 passes through the first hollow portion 111. More specifically, a part of the front end of the floating member 200 is located outside the first hollow portion 111, while the rear part of the floating member 200 is located inside the first hollow portion 111. Of course, as the distance between the floating member 200 and the circuit board 400 changes, the proportions of the parts of the floating member 200 located outside and inside the first hollow portion 111 will change. In another implementation manner, if the distance between the panel 650 of the wall-mounted air conditioner indoor unit to which the electric control box is applied and the front surface of the box body 100 of the electric control box is relatively far, it may also be that the entire floating member 200 is located outside the first hollow portion 111.

[0062] It should be noted that in this application, the floating driving member is connected to the circuit board 400, which does not mean that the floating driving member must be directly connected to the circuit board 400. For example, it may also be connected to a member fixedly arranged relative to the circuit board 400, that is, the fixing member 300.

[0063] Such as Figure 6 and Figure 7As shown, optionally, the display component includes a fixing member 300 fixedly installed on the circuit board 400. The fixing member 300 is provided with a first guiding portion 311, and the floating member 200 is provided with a second guiding portion 211. Relative sliding can occur between the fixing member 300 and the floating member 200 through the cooperation of the first guiding portion 311 and the second guiding portion 211.

[0064] By providing the fixing member 300 fixedly installed on the circuit board 400 and setting the first guiding portion 311 thereon to cooperate with the second guiding portion 211 provided on the floating member 200 to achieve relative sliding between the fixing member 300 and the floating member 200, the stability of the movement of the floating member 200 can be improved to ensure the position accuracy of the display information.

[0065] Specifically, in this embodiment, the first guiding portion 311 can be a part of the fixing member 300 and is integrally formed with the rest of the fixing member 300. Correspondingly, the second guiding portion 211 can be a part of the floating member 200 and is integrally formed with the rest of the floating member 200. The relative movement direction of the first guiding portion 311 and the second guiding portion 211, which is the sliding direction of the floating member 200 relative to the fixing member 300, can be perpendicular to the circuit board 400.

The third hollow portion 212, the second guiding portion 211 surrounding the third hollow portion 212, the second hollow portion 312, and the first display lamp 410 are correspondingly arranged. At least part of the second guiding portion 211 is continuously arranged around the corresponding third hollow portion 212, and the second guiding portion 211 extends from the floating member 200 towards the circuit board 400.

[0067] By providing a third hollow portion 212 in the floating member 200 and correspondingly providing a second hollow portion 312 and a first display lamp 410 in the fixed member 300, an illuminated area can be selectively formed according to the shape, size, and relative position of each third hollow portion 212, and the arrangement of each illuminated area can be used to display corresponding information. Moreover, the second guiding portion 211 is continuously provided around the third hollow portion 212, which can prevent the third hollow portion 212 from being illuminated by the corresponding first display lamp 410, thereby improving the accuracy of information display.

[0068] Among them, those skilled in the art should understand that the material and thickness of the fixed member 300 and the floating member 200 should ensure that the light emitted by the display component does not pass through the solid parts of the fixed member 300 and the floating member 200.

[0069] Among them, in this embodiment, the floating member 200 includes a floating plate body 230, and the third hollow portion 212 can be a long hole or a rectangular hole that penetrates the floating plate body 230 in the thickness direction. The third hollow portion 212 can be in two groups, and each group of the third hollow portions 212 is arranged in the shape of an 8 of a seven-segment display on the floating plate body 230. Therefore, each group of the third hollow portions 212 has seven, four vertically extending ones, and three horizontally extending ones. The four vertically extending third hollow portions 212 are arranged in two spaced vertical columns, and before the two vertical columns, one horizontally extending third hollow portion 212 is arranged in the upper, middle, and lower positions in sequence. Correspondingly, the arrangement of the second hollow portion 312 on the fixed plate body 330 of the fixed member 300 and the arrangement of the first display lamp 410 on the circuit board 400 are also in two groups, and each group is arranged in the shape of an 8 of a seven-segment display.

[0070] In this embodiment, the second guiding parts 211 provided around each third hollow part 212 are continuously arranged, that is, along the edge of each third hollow part 212 for one circle, the second guiding part 211 is continuous without gaps. In another implementation manner, if the second guiding parts 211 outside other third hollow parts 212 are continuous and can already block the light of other first display lamps 410, then the second guiding parts 211 outside this third hollow part 212 may not be continuous. For example, taking a seven-segment display showing the number 8 as an example, if among the three horizontally extending third hollow parts 212, the second guiding part 211 outside the middle third hollow part 212 is continuous, and the second guiding parts 211 outside the four vertically extending third hollow parts 212 are also continuous, then the second guiding parts 211 outside the horizontally extending third hollow parts 212 located at the upper part and the lower part may not be continuous. Because even if these second guiding parts 211 are not continuous, the light of other first display lamps 410 will not shine on these two third hollow parts 212. Or, among the four vertically extending third hollow parts 212, the third hollow parts 212 at the upper left and the lower right may be discontinuous respectively when the second guiding parts 211 outside the remaining third hollow parts 212 are continuous. Similarly, the second guiding parts 211 outside the third hollow parts 212 at the upper right and the lower left among the four vertically extending third hollow parts 212 may also be discontinuous because the light of the first display lamps 410 corresponding to the other third hollow parts 212 will not enter the third hollow parts 212 either.

[0071] Figure 16 The sectional view of the electric control box provided in the first embodiment of the present utility model; Figure 17 The three-dimensional sectional view of the electric control box provided in the first embodiment of the present utility model, wherein, Figure 17 As shown, the side wall of the first anti-retreat part abuting against the travel limit groove is shown, that is, the state where the floating part is farthest from the circuit board; Figure 18 The three-dimensional sectional view of the electric control box provided in the first embodiment of the present utility model cut from another direction; as Figures 6-18 shown, optionally, at least part of the first guiding part 311 of the fixing part 300 is continuously arranged around the corresponding second hollow part 312, and the first guiding part 311 extends from the fixing part 300 in a direction away from the circuit board 400; for the second guiding part 211 and the first guiding part 311, a part of one of them is always sleeved outside the other.

[0072] By providing the second guiding portion 211 on the fixing member 300 to surround the corresponding third hollow portion 212, it is possible to prevent the light emitted from the first display lamp 410 from diffusing around immediately, thereby improving the light concentration. By keeping a part of one of the first guiding portion 311 and the second guiding portion 211 always sleeved outside the other, it is possible to prevent the light of the first display lamp 410 from leaking out in the direction away from the circuit board 400. On the one hand, the light intensity of each third hollow portion 212 is increased, and on the other hand, the interference received by other third hollow portions 212 is reduced, thus improving the display effect.

[0073] Since the third hollow portion 212, the second hollow portion 312 and the first display lamp 410 are correspondingly arranged, the distribution of the second hollow portion 312 on the fixing member 300 is the same as the distribution of the third hollow portion 212 on the floating member 200, which will not be elaborated here. As for whether the first guiding portion 311 is partially continuous or entirely continuous, and how the discontinuous and continuous first guiding portions 311 are distributed, reference can be made to the continuous state of the second guiding portion 211, which will not be elaborated here.

[0074] In this embodiment, the fixing member 300 includes a fixing plate body 330. The second hollow portion 312 is a long hole penetrating the fixing plate body 330 in the thickness direction, and each first guiding portion 311 is an independent rectangular frame to surround the second hollow portion 312 therein. The second guiding portion 211 is formed by the crisscross plates provided on the rear side of the floating plate body 230. Each space surrounded by the crisscross plates can accommodate the first guiding portion 311, that is, a part of the second guiding portion 211 is always sleeved outside the corresponding first guiding portion 311. Of course, in this embodiment, the second guiding portion 211 is sleeved outside the first guiding portion 311. In another implementation manner, it can also be set that the first guiding portion 311 is sleeved outside the second guiding portion 211, that is, the first guiding portion 311 is formed by the plates arranged crisscross in front of the fixing plate body 330, and the second guiding portion 211 is an independent rectangular frame. In addition, in this embodiment, each first guiding portion 311 is continuously arranged around its corresponding second hollow portion 312. In another implementation manner, a part of the first guiding portion 311 can also be discontinuously arranged, and its specific distribution position and principle can refer to the introduction of the second guiding portion 211 surrounding the outside of the third hollow portion 212, which will not be elaborated here.

[0075] Such as Figures 6-15As shown, in addition, a fourth hollow portion 342 and a fifth hollow portion 352 are further provided on the fixing member 300, and a sixth hollow portion 242 and a seventh hollow portion 252 are provided on the floating member 200. The fourth hollow portion 342 and the sixth hollow portion 242 correspond to the second display lamp 420 on the circuit board 400, and the fifth hollow portion 352 and the seventh hollow portion 252 correspond to the third display lamp 430 on the circuit board 400.

[0076] Specifically, the fourth hollow portion 342 is rectangular, and the sixth hollow portion 242 can be in the shape of the letter 'e'. When projected in a direction perpendicular to the circuit board 400, the sixth hollow portion 242 completely falls within the range of the fourth hollow portion 342. When the second display lamp 420 lights up, the light emitted by it can pass through the sixth hollow portion 242 and project a luminous form of the letter 'e' on the panel 650. Moreover, a third guiding portion 341 is provided on the fixing member 300, and the third guiding portion 341 is continuously arranged around the fourth hollow portion 342. On the floating member 200, a fourth guiding portion 241 can also be provided, which is continuously arranged around the sixth hollow portion 242. The third guiding portion 341 is inserted into the fourth guiding portion 241 and is slidably arranged relative to the fourth guiding portion 241. More specifically, the third guiding portion 341 is formed by a rib plate portion provided on the front surface of the fixing member 300 enclosing an independent rectangular frame, and the fourth guiding portion 241 can be one of a plurality of rectangular grids formed by rib plate portions provided on the rear surface of the floating member 200.

[0077] The fifth hollow portion 352 is rectangular, and the seventh hollow portion 252 is also rectangular. A fifth guiding portion 351 is provided on the fixing member 300, and the fifth guiding portion 351 is continuously arranged around the fifth hollow portion 352, and the fifth guiding portion 351 is in the shape of a frustum of a pyramid. In this embodiment, a sixth guiding portion 251 is provided on the floating member 200, and the sixth guiding portion 251 may not be continuously arranged because the guiding portions arranged around the outer sides of the other hollow portions on the floating member 200 are already closed. Therefore, even when the third display lamp 430 lights up, it will not interfere with, for example, the third hollow portion 212 and the seventh hollow portion 252. In other words, precisely because the guiding portions arranged around the outer sides of the other hollow portions are closed, the lighting of the first display lamp 410 and the second display lamp 420 will not interfere with whether the seventh hollow portion 252 lights up.

[0078] As Figures 6-17 shown, optionally, among the fixing member 300 and the floating member 200, one is provided with a travel limit groove 380, and the other is provided with a travel limit portion 260. The travel limit portion 260 can slide in the travel limit groove 380. When the travel limit portion 260 abuts against the first side wall of the travel limit groove 380, the distance between the floating member 200 and the circuit board 400 is the farthest.

[0079] By providing the stroke limiting groove 380 and the stroke limiting portion 260, the maximum distance between the floating member 200 and the circuit board 400 can be limited, thereby preventing the floating member 200 from falling off the fixing member 300 during the process of installing the circuit board 400 into the electric control box after the display component is installed on the circuit board 400, and during the process of installing the electric control box onto the wall-mounted air conditioner indoor unit. This arrangement enables the display component to be first installed on the circuit board 400 and then the circuit board 400 to be installed into the electric control box. Compared with the solution of first installing the circuit board 400 into the box body 100, on the one hand, during the process of installing the display component on the circuit board 400, the display component can be effectively held and is not affected by the edge of the first hollow portion 111. On the other hand, the circuit board 400 during the installation of the display component can be placed in a suitable position, providing better support for the position of the direct mounting fixing member 300 of the circuit board 400 and preventing the circuit board 400 from being damaged during the installation process.

[0080] Specifically, in this embodiment, the fixing plate body 330 of the fixing member 300 is provided with a first plate portion 360 and a second plate portion 370 that extend forward substantially along the horizontal direction, with the first plate portion 360 being in the upper part and the second plate portion 370 being in the lower part. Stroke limiting grooves 380 are provided on the first plate portion 360 and the second plate portion 370. Herein, the stroke limiting grooves 380 in this embodiment penetrate along the plate thickness direction of the first plate portion 360 and the second plate portion 370. In fact, if the process permits, they can also be just grooves. And a stroke limiting portion 260 is provided on the floating member 200, and the stroke limiting portion 260 is arranged corresponding to the stroke limiting groove 380. Specifically, in this embodiment, the stroke limiting grooves 380 are arranged in an inverted pin shape with two on the upper part and one on the lower part, that is, two stroke limiting grooves 380 are spaced apart on the first plate portion 360, and one stroke limiting groove 380 is arranged approximately in the middle on the second plate portion 370. Correspondingly, the stroke limiting portion 260 is also arranged in an inverted pin shape with two on the upper part and one on the lower part on the floating member 200. The layout of the stroke limiting portion 260 and the stroke limiting grooves 380 in a three-point layout restricts the floating member 200 relative to the fixing member 300 at three points of a triangle to ensure that the floating member 200 does not completely come out of the fixing member 300. Of course, in other implementation manners, the stroke limiting grooves 380 can also be provided on the floating member 200 and the stroke limiting portion 260 is provided on the fixing member 300; or the stroke limiting grooves 380 and the stroke limiting portion 260 correspondingly present a layout with one on the upper part and two on the lower part.

[0081] Specifically, the stroke limiting portion 260 extends rearward from the floating plate body 230. The stroke limiting portion 260 includes a first root portion 261 and a second anti-retreat portion 262. The first root portion 261 is plate-shaped, and the second anti-retreat portion 262 is wedge-shaped. The wedge-shaped second anti-retreat portion 262 is connected to one end of the first root portion 261 and is larger than the end of the first root portion 261 connected to the second anti-retreat portion 262. That is, a second anti-retreat surface 263 can be formed on the end surface of the second anti-retreat portion 262 facing the floating plate body 230. The second anti-retreat surface 263 can hook the front side wall of the stroke limiting groove 380, thereby limiting the maximum distance between the floating member 200 and the circuit board 400. Moreover, the second anti-retreat surfaces 263 of the respective second anti-retreat portions 262 can be located in the opposite direction of their corresponding first root portions 261. Specifically, for the two stroke limiting portions 260 on the upper part of the floating member 200 in this embodiment, their second anti-retreat surfaces 263 are located above their first root portions 261, while for the stroke limiting portion 260 on the lower part of the floating member 200, its second anti-retreat surface 263 is located below its first root portion 261. With such a configuration, it can be prevented that moving in a certain direction can unlock all the second anti-retreat portions 262 from the stroke limiting groove 380. Since the stroke limiting portion 260 is not an absolute rigid body, during the process of inserting the stroke limiting portion 260 into the stroke limiting groove 380, when the second anti-retreat portion 262 contacts the first plate body portion 360 and the second plate body portion 370, it can be compressed to bend the first root portion 261. And after the second anti-retreat portion 262 completely enters the stroke limiting groove 380, the first root portion 261 can rebound, and of course, the rebound may not completely return to the state where the elastic force of the first root portion 261 disappears. That is, after the second anti-retreat portion 262 enters the stroke limiting groove 380, the first root portion 261 may still abut against the first plate body portion 360 and the second plate body portion 370 under the action of the elastic force.

[0082] As Figure 12 、 Figure 14 and Figures 19-20 shown, optionally, among the floating member 200 and the fixing member 300, one is provided with a spring support post 270, and a compression spring (not shown in the figure) is sleeved on the spring support post 270, and the compression spring abuts against the other of the floating member 200 and the fixing member 300.

[0083] By providing a spring support post 270 in one of the floating member 200 and the fixing member 300 to sleeve the compression spring and abut against the other, the floating member 200 can be subjected to the acting force of the compression spring, so that the floating member 200 can be closely attached to the rear side of the panel 650 of the wall-mounted air conditioner indoor unit, ensuring clear display information.

[0084] Specifically, in this embodiment, the compression spring can be a cylindrical helical compression spring or an elastic sleeve. The spring support column 270 is disposed on the rear side of the floating plate body 230 of the floating member 200. Specifically, the spring support column 270 has a plurality of right trapezoidal rib plates arranged in a cross shape, perpendicular to each other and perpendicular to the floating plate body 230. The spring support column 270 is generally tapered with a smaller free end, so that the compression spring can be sleeved on the spring support column 270. Of course, in another implementation, the spring support column 270 can also be disposed on the front side of the fixed plate body 330. Of course, in another implementation, the floating driving member can also be an arched elastic sheet, with the middle of the arched elastic sheet abutting one of the floating member 200 and the fixed member 300, and the end of the arched elastic sheet abutting the other one.

[0085] The spring support column 270 can be located in the middle region of the upper and lower two spaces where each group of second guiding portions 211 are distributed in an 8-shaped pattern. That is, if two sets of third hollow portions 212 are provided on the floating member 200, a total of four spring support columns 270 are provided, and one spring support column 270 is provided in each of the two regions between the second guiding portions 211 in each group of second guiding portions 211.

[0086] As Figures 8-11 and Figures 16-17 shown, optionally, the fixing member 300 is provided with a fixing tongue 390, and the circuit board 400 is provided with a fixing hole 440. The fixing tongue 390 is inserted through the fixing hole 440, and the first anti-retreat portion 392 of the fixing tongue 390 abuts against the rear side of the circuit board 400.

[0087] By providing the fixing tongue 390 and using the first anti-retreat portion 392 of the fixing tongue 390 to abut against the rear side of the circuit board 400, after the fixing tongue 390 is inserted into the circuit board 400, the fixing member 300 can be prevented from detaching from the circuit board 400 to achieve reliable fixation of the fixing member 300 and the circuit board 400.

[0088] It should be noted that the fixing hole 440 on the circuit board 400 penetrates along the thickness direction of the circuit board 400, so that the fixing tongue 390 can penetrate from the front side of the circuit board 400 and the first anti-retreat portion 392 abuts against the rear side of the circuit board 400, that is, the back side of the circuit board 400.

[0089] Specifically, in this embodiment, there may be three fixing holes 440 on the circuit board 400, arranged in a triangular formation with one on top and two below. Specifically, each fixing hole 440 may be rectangular. The position of the fixing tongue 390 is correspondingly set with the fixing hole 440. That is, in the middle of the first plate body portion 360, one fixing tongue 390 is provided, and at both ends of the second plate body portion 370, one fixing tongue 390 is respectively provided. That is, on the first plate body portion 360, the fixing tongue 390 is located between the two stroke limiting grooves 380, and on the second plate body portion 370, the stroke limiting grooves 380 are located between the two fixing tongues 390.

[0090] The fixing tongue 390 includes a second root portion 391 and a first anti-retreat portion 392. The second root portion 391 is plate-shaped, and the first anti-retreat portion 392 is wedge-shaped. The wedge-shaped first anti-retreat portion 392 is connected to one end of the second root portion 391 and is larger than the end of the second root portion 391 connected to the first anti-retreat portion 392. That is, on the end face of the first anti-retreat portion 392 facing the floating member 200, a first anti-retreat surface 393 may be formed, and this first anti-retreat surface 393 can hook the rear side of the circuit board 400. Moreover, the first anti-retreat surfaces 393 of the respective first anti-retreat portions 392 may be located in the opposite direction of their corresponding second root portions 391. Specifically, for the stroke limiting portion 260 on the upper part of the fixing member 300 in this embodiment, its first anti-retreat surface 393 is located above its second root portion 391, and for the fixing tongue 390 on the lower part of the fixing member 300, its first anti-retreat surface 393 is located below its second root portion 391. With such a configuration, it can be prevented that moving in a certain direction can unlock all the first anti-retreat portions 392 from the fixing holes 440. Since the fixing tongue 390 is not an absolute rigid body, during the process of inserting the fixing tongue 390 into the fixing hole 440, when the first anti-retreat portion 392 contacts the side wall of the fixing frame, it can be compressed to bend the second root portion 391, and when the first anti-retreat surface 393 completely passes over the fixing hole 440, the second root portion 391 can rebound. Of course, the rebound may not completely rebound to the state where the elastic force of the second root portion 391 disappears. That is, when the first anti-retreat portion 392 enters the fixing hole 440, the second root portion 391 may still be in contact with the side wall of the fixing hole 440 under the action of the elastic force.

[0091] As Figures 8-11 and Figures 16-17 shown, optionally, the fixing member 300 includes a first convex rib 331 and a first plate body portion 360. The first plate body portion 360 is disposed opposite to the first convex rib 331 and forms a first groove 332; the box body 100 is provided with a second convex rib 114 at the edge of the first hollow portion 111, and the second convex rib 114 is matched with the first groove 332.

[0092] By setting the first plate body part 360 and the first convex rib 331 to form a first groove 332, and using the second convex rib 114 to match with the second groove, a labyrinth seal can be formed by the two to prevent the condensation on the front surface of the box body 100 from flowing into the display component and further flowing onto the circuit board 400, thereby improving the reliability of the electric control box.

[0093] Specifically, in this embodiment, the first convex rib 331 is located at the upper end of the front surface of the fixing plate body 330 of the fixing member 300, and is arranged at a relative interval with the first plate body part 360. The second convex rib 114 is arranged on the inner surface of the front wall of the box base 110, that is, the rear surface of the front wall of the box base 110, and matches with the first groove 332.

[0094] As Figures 3-5 and Figure 16 、 Figure 17 shown, optionally, the first hollow part 111 is a notch part. The box body 100 includes a box base 110 and a box cover 120 fastened to the box base 110. The bottom wall of the box base 110 is provided with a first slot 112, and the bottom of the circuit board 400 is inserted into the first slot 112; the top wall of the box base 110 is provided with a second slot 113, and the top of the circuit board 400 is inserted into the second slot 113; the opening direction of the notch part, the extending directions of both the first slot 112 and the second slot 113 are parallel to the direction in which the box cover 120 is fastened to the box base 110.

[0095] By providing the first slot 112 on the bottom wall of the box base 110 of the circuit board 400 to insert the bottom of the circuit board 400, and providing the second slot 113 on the top wall of the box base 110 to insert the top of the circuit board 400, the upper and lower edges of the circuit board 400 can be positioned, so that the circuit board 400 can maintain its position and pitch in the front - rear direction, thereby improving the installation stiffness of the circuit board 400. Moreover, making the opening direction of the notch part as the first hollow part 111 and the extending directions of the first slot 112 and the second slot 113 all parallel to the direction in which the box cover 120 is fastened to the box base 110 can install the display component in place simultaneously while inserting the circuit board 400, improving the installation efficiency.

[0096] Specifically, in this embodiment, both the first slot 112 and the second slot 113 extend in the left - right direction, and the slot openings are both at the right end of the box base 110. The first hollow part 111 is a notch part opening to the right. Inserting the circuit board 400 left - ward along the first slot 112 and the second slot 113 until it is in place, the display component can also be installed in place.
