Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a panel middle frame assembly and an air conditioner. Background Art

[0002] In existing air conditioners, according to the requirements of electrical safety, the air conditioner must meet safety regulations in design. One of them is that the electrical control area must be isolated from the outside world, including the middle frame wiring cover that must be opened with tools, and human fingers cannot directly touch the electrical control box after removing the filter.

[0003] In order to prevent people from touching the electric control box after removing the filter, a protective plate is designed inside the middle frame to isolate the electric control box. The internal structure of the traditional middle frame does not need to consider the appearance too much, but in the integrated panel and middle frame structure, the panel display area is a thinning area, and the protective plate is located exactly in the panel display area. The connection between the protective plate and the panel display area will cause appearance defects; and if the ribs connecting the protective plate and the panel are too thick, the rubber on it will shrink at a different speed than the panel, which is easy to cause shrinkage pits on the panel. Summary of the invention

DETAILED DESCRIPTION

[0043] The object of the present invention is to provide a panel middle frame assembly and an air conditioner, wherein a gap is provided between the protective plate and the panel display area to avoid appearance defects; and the strength of the protective plate is improved by multiple reinforcements to avoid the risk of twisting and breaking of the protective plate.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] [First embodiment]

[0046] See also Figure 1 The first embodiment of the present invention provides a panel middle frame assembly 100, including a panel 110, and a panel display area 111 arranged on the panel 110, and also includes: a protective plate 120. Among them, the protective plate 120 is arranged on the back of the panel 110, and the protective plate 120 does not contact the panel display area 111. The side of the protective plate 120 close to the panel display area 111 is the display side 130, which is used to install electronic control components, and the protective plate 120 can block the electronic control components to prevent the hand from being directly extended into the display side 130 from the other side of the protective plate 120 and contacting the electronic control components, which may cause danger.

[0047] In a specific embodiment, the protective plate 120 is connected to the panel 110 on one side of the panel display area 111 and extends toward the panel display area 111, with the extended end suspended above the panel display area 111, so that the panel display area 111 will not be connected to the protective plate 120 and deformed, causing appearance defects of the panel 110.

[0048] Preferably, combined Figure 1 and Figure 2 The protective plate 120 includes, for example, a protective plate body 121, a panel connection portion 122, and a suspended portion 123. The panel connection portion 122 is disposed on the protective plate body 121 and is located on a side close to the panel 110; the suspended portion 123 is disposed on the protective plate body 121 and is located on a side close to the panel display area 111, and a gap d is provided between the suspended portion 123 and the panel display area 111. The gap d should first be smaller than the thickness of a finger to prevent the finger from being inserted into the gap and causing an electric shock.

[0049] Among them, one end of the suspended portion 123 away from the protective plate body 121 is located at a position exceeding 1 / 2 of the panel 110, further preventing the hand from touching the said electronic control element; the length of the protective plate 120 in the up and down directions gradually decreases from the protective plate body 121 to the suspended portion 123, so as to cooperate with the evaporator.

[0050] Preferably, the suspended portion 123 is provided with at least one vertical reinforcement 125 and at least one horizontal reinforcement 124 , and the vertical reinforcement 125 and the horizontal reinforcement 124 are staggered and connected, so as to improve the bending resistance of the suspended portion 123 .

[0051] For example, a horizontal reinforcement 124 is provided on the bottom surface of the suspended portion 123, and the horizontal reinforcement 124 connects one end of the suspended portion 123 away from the protective plate body 121 and the protective plate body 121; the suspended portion 123 is provided with two parallel vertical reinforcements 125 above the horizontal reinforcement 124, thereby further improving the bending resistance of the suspended portion 123.

[0052] Furthermore, a vertical reinforcement 125 is provided at the end of the suspended portion 123, thereby improving the strength of the end of the suspended portion 123; a vertical reinforcement 125 is connected in the middle of the horizontal reinforcement 124, thereby preventing the suspended portion 123 from twisting and deforming.

[0053] Furthermore, the cross-sectional shape of the horizontal reinforcement 124 and the vertical reinforcement 125 is, for example, a triangle, so as to obtain a more stable structure.

[0054] Preferably, see Figure 3-Figure 5 The side of the protection plate 120 away from the panel display area 111 is the ejection side 140, wherein the gap between the suspended portion 123 and the panel display area 111 is used to set the ejection slider 141. And the height of the gap gradually increases along the display side 130 toward the ejection side 140, so that the ejection slider 141 can slide out from the ejection side 140.

[0055] Specifically, the suspended portion 123 includes a mold release surface at the bottom end of the suspended portion 123, and the mold release surface gradually tilts upward along the display side 130 toward the mold release side 140. The horizontal reinforcement member 124 and the vertical reinforcement member 125 face the mold release side 140, and on the basis that the suspended portion 123 is provided with the horizontal reinforcement member 124, the mold release surface is the bottom surface of the horizontal reinforcement member 124.

[0056] Furthermore, the panel display area 111 is a recessed area on the back of the panel 110, including a central display plane 111a and an inclined thinning surface 111b surrounding the display plane 111a. The thickness of the display plane 111a is, for example, 1.4 mm, the thickness of other positions of the panel 110 is, for example, 2.4 mm, and the width of the thinning surface 111b is, for example, 40 mm.

[0057] Preferably, the angle α between the ejection surface and the display plane 111a is greater than five times the slope β of the thinning surface 111b, to prevent the ejection slider 141 from damaging the panel display area 111 during the ejection process. For example, the slope of the ejection surface is α=8°, and the slope of the thinning surface 111b is β=1.3°.

[0058] Preferably, combined Figure 2 , Figure 6 , Figure 7 The panel middle frame assembly 100 , for example, further includes: an anti-twisting reinforcement 150 , which is connected between the suspended portion 123 and the panel connecting portion 122 to prevent the suspended portion 123 from twisting and deforming toward the ejection side 140 .

[0059] Furthermore, the panel midframe assembly 100 further includes an oblique reinforcement 126 connected between the horizontal reinforcement 124 and the anti-twist reinforcement 150 and extending upward to improve the strength of the protective plate body 121. The anti-twist reinforcement 150 is located at the demolding side 140 and connected to the oblique reinforcement 126.

[0060] The anti-twisting reinforcement member 150 is, for example, a triangular reinforcement rib structure, thereby further enhancing the strength of the protection plate body 121 .

[0061] Furthermore, the anti-twisting reinforcement 150 is connected to the horizontal reinforcement 124 and is located on the same horizontal plane, that is, the anti-twisting reinforcement 150 and the horizontal reinforcement 124 are respectively located on both sides of the oblique reinforcement 126, further preventing the hanging portion 123 from bending toward the mold release side 140. For example, the distance L3 between the anti-twisting reinforcement 150 and the panel 110 is 4 to 6 mm, such as 5 mm.

[0062] Preferably, the thickness L1 of the panel connection portion 122 is 1 / 3 to 1 / 2 of the thickness L2 of the protective plate body 121, so as to avoid the adhesive of the panel connection portion 122 being too thick, which causes its shrinkage speed to be different from that of other positions of the panel 110, and a shrinkage pit appears at the position of the panel 110 corresponding to the panel connection portion 122. For example, L1 = 0.8 mm, L2 = 2.3 mm.

[0063] Furthermore, the panel connection part 122 also includes a plurality of panel connection ribs 122a, which are evenly arranged between the protective plate body 121 and the panel 110. The panel connection ribs 122a are located at the demolding side 140 of the protective plate 120, and their height is lower than the anti-twist reinforcement 150, i.e., less than 5 mm. In addition, two adjacent panel connection ribs 122a form a groove structure at the demolding side 140, thereby reducing the thickness of the panel connection part 122 while ensuring the connection strength of the panel connection part 122.

[0064] Preferably, combined Figure 3 , Figure 8 and Fig. 9 The panel middle frame assembly 100, for example, further includes other reinforcement members 160, which are located on the display side 130 and are used to support the protective plate 120. The height of the other reinforcement members 160 is greater than the height of the panel connection rib 122a on the mold release side 140. For example, the height L4 of the other reinforcement members 160 is 8 to 10 mm, so that the other reinforcement members 160 can improve the connection strength between the protective plate body 121 and the panel connection part 122 while supporting the protective plate 120. The width L5 of the other reinforcement members 160 is, for example, 6 to 8 mm, and the thickness L6 is, for example, 0.8 mm.

[0065] Furthermore, a plurality of other reinforcing members 160 are disposed at intervals. For example, the panel midframe assembly 100 is provided with four other reinforcing members 160 on the display side 130 , and are disposed at equal intervals.

[0066] Preferably, combined Figure 1 The panel middle frame assembly 100 further includes, for example, a middle frame 170. The middle frame 170 is connected to the panel 110 and to the side of the protective plate body 121 away from the suspended portion. The end of the oblique reinforcement 126 away from the panel 110 connection piece is connected to the middle frame 170, thereby improving the connection strength between the protective plate 120 and the middle frame 170 and the panel 110.

[0067] Furthermore, the panel 110 and the middle frame 170 may be an integrated structure or a spliced ​​structure.

[0068] [Second embodiment]

[0069] See also Fig.10 The second embodiment of the present invention provides an air conditioner 200, comprising: the panel middle frame assembly 100 provided in the first embodiment, and an evaporator 210. The evaporator 210 is housed in the panel middle frame assembly 100 and is located on one side of the protective plate 120.

[0070] Specifically, the evaporator 210 is located at the demolding side 140 of the protective plate 120, and a distance is provided between the evaporator 210 and the protective plate 120 to accommodate the pipeline of the evaporator 210. For example, an evaporator side plate 211 is provided at one end of the evaporator 210 facing the protective plate 120 to fix the pipeline; the distance between the evaporator side plate 211 and the protective plate 120 is 8 to 10 mm, so that when the air conditioner is shaken or dropped during transportation, the pipeline of the evaporator 210 will not be hit and quality problems will not occur.
