The spacer 146 may protrude from the bottom wall of the display housing 14 toward the front of the door 1. The spacer 146 may also be attached to a sidewall of the display housing 14.

In the above embodiment, the handle housing 15 and the display housing 14 are separately manufactured and form the handle groove 3 and the mounting cavity 140, respectively. It is to be understood that the invention is not limited to the following, but may be embodied in various forms. For example, at least a portion of the handle housing 15 may be integrally formed with at least a portion of the display housing 14, e.g., a body portion of the handle housing (e.g., forming at least a portion of a handle slot wall) may be integrally formed with the display housing 14.

The door 1 includes a passage 100 exposed to one side of the door 1, the passage 100 communicating with the installation cavity 140. In this embodiment, the channel 100 has an inlet 138 located in the upper sidewall 139.

Referring to fig. 2, 3, 5 and 7, the door 1 includes a fixing member 18 adapted to be inserted into the door 1 through a passage 100 to fix the display device 2.

In this embodiment, the securing member 18 is adapted to be inserted into the channel 100 via an entrance 138 of an upper side wall 139 of the door 1 to secure the display device 2. It should be understood that the present invention should not be limited thereto but may be applied to a case where the entrance of the passage 100 is provided at the lower side, or left/right side, of the door 1.

The fixing member 18 has a first abutting portion 181 for abutting the display device 2 in the front-rear direction. Accordingly, the display device 2 includes a second abutting portion 203 for cooperating with the first abutting portion 181.

The fastener 18 may include a body portion 180 positioned within the channel 100. The first abutting portion 181 extends from the end of the main body portion 180 into the mounting cavity 140.

In the present embodiment, the fixing member 18 supports the display device 2 backward, so the first supporting portion 181 is located in front of the second supporting portion 203 to prevent the display device 2 from falling off forward from the mounting opening 1401 of the mounting cavity 140.

The display device 2 includes a first end 201 (the first end is an upper end in this embodiment) connected to the fixing member 18 and a second end 202 (the second end is a lower end in this embodiment) opposite to the first end. As shown in fig. 3 and 8, the door 1 includes a first positioning structure 148 that may be used to position the second end of the display device 2. The first positioning structure 148 may include a slot 1481 parallel to the mounting opening 1401 and an insertion portion 1482 inserted into the slot 1481.

The slot 1481 may be disposed at the second end 202 of the display device 2 and the insert section 1482 may be disposed within the mounting cavity 140. Or vice versa.

In this embodiment, the insert section 1482 is disposed at the bottom of the mounting cavity 140 and projects upwardly beyond the lower edge of the mounting cavity 140.

In assembly, as shown in fig. 8, the second end 202 of the display device 2 is first inserted into the mounting cavity 140 obliquely through the mounting opening 1401, so that the insertion portion 1482 is inserted into the insertion slot 1481. The first end 201 of the display device 2 is then pressed into the mounting cavity 140. The fastener 18 is then inserted into the channel 100 from the inlet 138. The first abutting portion 181 extends into the mounting cavity 140 and abuts against the upwardly protruding second abutting portion 203, so as to press the first end 201 of the display device 2 backwards.

The fastener 18 is secured within the channel 100. The fastener 18 includes a proximal end 1801 facing the entrance 138 of the passageway 100 and a distal end 1802 opposite the proximal end 1801. The door 1 includes a securing means for securing the proximal end 1801 within the door 1.

As shown in fig. 5, the fixture includes a mounting block 136 located within the channel 100. The mounting stand 136 is perpendicular to the insertion direction Y in the insertion channel 100 of the fixture 18.

The securing means includes a securing lip 183 for securing the proximal end 1801 facing the inlet 138 to the end cap 13. The securing lip 183 projects outwardly from the body portion 180 and rides on the mounting land 136 of the end cap 13 that is exposed to the channel 100.

The fixed edge 183 overlaps the mounting block 136. The securing means may include a screw 6 to secure the securing edge 183 to the mounting block 136.

The door 1 includes a second locating feature to locate the distal end 1802 within the channel 100 to prevent the distal end 1802 of the fastener 18 from moving in the front-to-back direction and/or the left-to-right direction of the door 1.

The second positioning structure may include a positioning protrusion 149 and a positioning hole, the positioning protrusion 149 being inserted into the positioning hole along a direction parallel to the insertion direction Y of the fixture 18 into the channel 100. In this embodiment, the locating holes may be formed by passages 52 through the fixture 18. In further embodiments, the locating holes may also be formed by holes separate from the passageway 52.

The positioning projection 149 and the passage 52 can be plug-connected in the insertion direction Y along the fixture 18. When the fastener 18 is inserted into the channel 100, the locating projection 149 is inserted into the passageway 52.

The locating projection 149 extending into the passageway 52 causes the distal end 1802 of the anchor 18 to be held against the locating projection 149. This can restrict the distal end 1802 of the fixing member 18 from moving in the front-rear direction, so that even when the passage 100 has a defect in the form-fit due to a clearance between the passage 100 and the fixing member 18 due to manufacturing tolerances, it is possible that the position of the distal end 1802 of the fixing member 18 in the front-rear direction is accurately defined by the second positioning structure. It will be readily appreciated that by appropriately configuring the shapes and positions of the positioning projections 149 and the positioning holes, it is possible to prevent the distal end 1802 of the fixing member 18 from being positioned in both the front-rear direction and/or the left-right direction of the door 1 by the second positioning structure.

In this embodiment, one end of the positioning protrusion 149 is connected to the bottom wall of the mounting cavity 140, and the free end thereof extends into the channel 100.

The door 1 may include a spring 182, the spring 182 being located between the fixing member 18 and the inner wall of the passage 100. In this embodiment, the resilient tab 182 is located between the front side of the fastener 18 and the front inner wall 1001 of the channel 100. When the fixing member 18 is fixed in the channel 100, the elastic sheet 182 abuts against the front inner wall 1001 of the channel 100. The spring plate 182 may be integrally formed on the fixing member 18.

The directions of the forces received by the fixing member 18 through the first abutting portion 181 and the elastic sheet 182 are opposite, so as to enhance the abutting force of the fixing member 18 on the display device 2.

In one embodiment, the hot air flows through the fixing member 18, so that the fixing member 18 is exposed to the heat dissipation duct 5.

The fixing member 18 is provided with a passage 52, so that a part of the heat dissipation duct 5 is located in the fixing member 18, and hot air can flow through the fixing member 18.

The receiving case 16 may include an extension 162 located outside the receiving chamber 16. Extension 162 is provided with a first fixing hole 163 to fix accommodating case 16 to side wall 139. The extension portion 162 may be further provided with a second fixing hole 164 to fix the cover 17 to the receiving case 16 along the opening of the receiving chamber 161.

Extension 162 may be located at one end of containment housing 16. The second ventilation opening 51 is provided in the extension portion 162. In the present embodiment, the plurality of second ventilation openings 51 are located between the first mounting hole 163 and the opening of the accommodating chamber 161, and therefore the second ventilation openings 51 and the accommodating chamber 161 are staggered in the direction in which air flows out/in from the second ventilation openings 51.

At least one wall of the accommodating chamber 161 located in the inner space 132 is exposed to the heat dissipation duct 5 on a side facing away from the accommodating chamber 161. For example, in one embodiment, the bottom wall and the side wall of the accommodating chamber 161 facing the opening are exposed to the heat dissipation duct 5.

According to the embodiment of the present invention, the accommodating chamber 161 is isolated from the heat dissipation duct 5 to prevent hot air from entering the accommodating chamber 161 to affect the electric device 20. In one embodiment, the walls of the receiving chamber 161 exposed within the heat dissipation duct 5 are all seamless. In another embodiment, the hole 165 of the accommodating chamber 161 exposed to the heat dissipation duct 5 (e.g., a hole through which the cable passes) may be closed by a closing means such as a tape or a sponge.

After flowing from the inside of the display housing 14 to the inner space 132, the air flows laterally along the passage 54 located below the accommodating housing 16 to the gap G between the end cover 13 and the end of the accommodating housing 16 provided with the extension 162, and flows out through the second ventilation opening 51.

A liquid guide chamber 510 and a liquid guide opening 511 located on the side wall of the liquid guide chamber 510 are provided just below the second ventilation opening 51. The diversion port 511 is communicated with the outside of the door 1. When the liquid inadvertently enters the liquid guiding chamber 510 through the second ventilating opening 51, the liquid can be discharged out of the door 1 through the guiding opening 511. So that liquid is prevented from entering the display housing 14.

The various embodiments described in connection with fig. 1-8 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than the illustrated means may be used in general as long as the same effects can be achieved by the means.
