Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

An electric control box is arranged in the indoor unit of the air conditioner and comprises a box body and a circuit board arranged in the box body, and the indoor unit of the air conditioner controls other electronic components through the circuit board. The existing indoor unit comprises a face frame and a chassis positioned in the face frame. The face frame has a top wall surface and a bottom wall surface, and the chassis has a back wall surface. When the indoor unit is installed, the chassis is connected to the wall, and the back wall surface is attached to the wall. In the conventional indoor unit, the top wall surface of the face frame is arranged obliquely, specifically, the vertical height of the part of the top wall surface, which is far away from the back wall surface, is lower. When the roof is set up as above, on the one hand, the roof of slope setting makes the roof can not laminate the ceiling because of the installation height is too high when the indoor set is installed, and no matter how high the indoor set installation is promptly, has sufficient clearance between roof and the ceiling of indoor set to make things convenient for indoor set to follow top air inlet. On the other hand, the indoor unit can further comprise a front panel connected to the front side of the face frame, the front panel is rotationally connected with the face frame and can rotate relative to the face frame and turn upwards, the front panel can be conveniently turned upwards when a gap exists between the indoor unit and the ceiling, and position interference between the front panel and the ceiling is prevented from being generated so that the indoor unit cannot be opened.

In the related art, the electric control box is arranged in the face frame and connected to the chassis, the circuit board of the electric control box is a rectangular plate, and the thickness direction of the circuit board is parallel to the back wall surface and the bottom wall surface. In order to find the benchmark when being convenient for the installation of automatically controlled box, the automatically controlled box uses the back wall surface to carry out the position arrangement as the benchmark, and the front side and the back side of circuit board are all on a parallel with the back wall surface this moment, and the upper side and the lower side of circuit board are all perpendicular to the back wall surface. However, the indoor unit has a limited internal space, a small usable space of the circuit board, and a high arrangement density of the individual electronic control elements on the circuit board, resulting in a high cost of the circuit board. The space above the circuit board is difficult to use because the space above the circuit board is obliquely arranged, the space below the circuit board is difficult to use because the driving motor needs to be arranged in the space below the circuit board, and the space on the front side of the circuit board is also difficult to use when the height of the circuit board needs to meet the corresponding size requirement. In summary, the arrangement of the positions of the existing electric control boxes makes the volume of the circuit board difficult to be large, so that the arrangement density of each electric control element on the circuit board is large, and the cost is high.

In view of this, the embodiment of the first aspect of the present utility model provides an indoor unit 10, which can more reasonably utilize the internal space of the indoor unit 10, and increase the volume of the circuit board 220 to reduce the arrangement density of the electric control elements, thereby reducing the cost. An indoor unit 10 according to an embodiment of the present utility model is described below with reference to fig. 1 to 9. Specifically, the indoor unit 10 includes a housing assembly 100 and an electronic control box 200.

Referring to fig. 1 and 2, the housing assembly 100 may define a cavity for receiving the electronic control cartridge 200.

With reference to fig. 1 and 5, a specific arrangement of the top wall surface 111 is described below. The top wall surface 111 is disposed obliquely in a direction away from the back wall surface 121 toward a direction approaching the bottom wall surface 112. In other words, the top wall surface 111 is arranged obliquely in a direction approaching the back wall surface 121 toward a direction departing from the bottom wall surface 112. Referring to the orientation of fig. 5, i.e., in the right-to-left direction, the top wall surface 111 is disposed obliquely downward. The top wall surface 111 of the scheme adopts an inclined arrangement, so that a sufficient gap is formed between the top wall surface 111 and the upper ceiling of the top wall surface, and the indoor unit 10 can conveniently enter air from the top.

Referring to fig. 1 to 5, a specific arrangement of the electronic control box 200 is described below. The electronic control box 200 is disposed in the housing assembly 100, and the specific disposition position of the electronic control box 200 may be determined according to practical situations, and the electronic control box 200 may be connected to the housing assembly 100. It is understood that the electronic control box 200 may be removably coupled to the housing assembly 100 to facilitate replacement and maintenance of the electronic control box 200. The electronic control box 200 includes a box body 210 and a circuit board 220, wherein the circuit board 220 is disposed inside the box body 210.

Referring to fig. 5, the relative arrangement of the electronic control box 200 and the housing assembly 100 is described below.

Specifically, the circuit board 220 includes a first side 221 proximate the top wall 111. The first side 221 is disposed obliquely in a direction away from the back wall surface 121 toward a direction approaching the bottom wall surface 112. In other words, the first side 221 is disposed obliquely in a direction away from the bottom wall surface 112 in a direction approaching the back wall surface 121. Referring to the orientation of fig. 5, the first side 221 is a side of the upper side of the circuit board 220, and the first side 221 is disposed obliquely downward in the right-to-left direction, and the specific inclination angle of the first side 221 may be dependent on practical situations.

In the technical scheme of the utility model, the indoor unit 10 comprises a shell assembly 100 and an electric control box 200. The housing assembly 100 has a top wall surface 111, a bottom wall surface 112, and a back wall surface 121. The top wall surface 111 is disposed obliquely in a direction away from the back wall surface 121 toward a direction approaching the bottom wall surface 112. The electronic control box 200 is disposed in the housing assembly 100 and connected to the housing assembly 100, and the electronic control box 200 includes a box body 210 and a circuit board 220 disposed in the box body 210. In the prior art, the top wall surface above the circuit board is arranged obliquely, so that the space above the circuit board is difficult to use, the space below the circuit board is difficult to use because a driving motor is required to be arranged, and the space on the front side of the circuit board is also difficult to use when the height of the circuit board is required to meet the corresponding size requirement. That is, the available space of the circuit board is small, and the arrangement density of each electric control element on the circuit board is large, resulting in high cost of the circuit board. The circuit board 220 of the present embodiment includes a first side 221 close to the top wall surface 111, and the first side 221 is disposed obliquely toward the bottom wall surface 112 in a direction away from the back wall surface 121, i.e., the circuit board 220 is adapted to the top wall surface 111 in an oblique arrangement. Therefore, the present solution can adapt to the structure and the position layout of the housing assembly 100 and the driving motor 310, fully utilize the upper space, the lower space and the front space of the circuit board 220, increase the arrangement volume of the circuit board 220, reduce the arrangement density of the electric control elements, and reduce the cost of the circuit board 220. For example, referring to fig. 5, compared to the existing circuit board (the components illustrated by the dashed lines in fig. 5), the present solution can effectively increase the volume of the circuit board 220 by making the length of the circuit board 220 as large as possible while ensuring the height of the circuit board 220.

Specifically, the top wall surface 111 has a first end line 1111 and a second end line 1112 arranged opposite to each other. The first end line 1111 is an end line of the top wall surface 111 near the end of the back wall surface 121, and the second end line 1112 is an end line of the top wall surface 111 facing away from the end of the back wall surface 121. Referring to the fig. 5 orientation, i.e., the right end line of the top wall surface 111 is the first end line 1111 and the left end line of the top wall surface 111 is the second end line 1112. In fig. 5, the first end line 1111 and the second end line 1112 are both dot-shaped and the reference plane 1113 is linear. The plane where the first end line 1111 and the second end line 1112 are located together is the reference plane 1113.

In other embodiments, the first side 221 may be a combination of straight and curved lines, and some embodiments of the present application are described by taking the first side 221 as a straight line.

Referring to fig. 5, the tilting arrangement of the circuit board 220 is described below. To facilitate description and understanding of the specific inclination angle of the first side 221 of the circuit board 220, a reference line 225 is defined. The line connecting the end of the first side 221 facing away from the back wall 121 and the end near the back wall 121 is set as a reference line 225, and as an example of the orientation of fig. 5, the line connecting the left end and the right end of the first side 221 is set as the reference line 225 (when the first side 221 is a straight line segment, the straight line where the first side 221 is located is the reference line 225). The reference line 225 forms an angle b with the back wall 121. Wherein a≤b <90 °, in other words, the reference line 225 and the reference surface 1113 are each arranged obliquely, and the inclination angle of the reference line 225 is smaller than or equal to the inclination angle of the reference surface 1113.
