Description

Technical Field

[0001] This utility model belongs to the field of air conditioner accessories, specifically relating to display structures and air conditioners. Background Technology

[0002] An air conditioner's indoor unit casing has a display structure to show the temperature or air conditioning mode. In existing technology, the display structure is assembled onto the air conditioner casing via a display box. The casing has a through-hole, allowing the display panel to be aligned with the through-hole and thus observed. Due to the unique cooling and heating noise of air conditioners, a gap must be left between the display box and the casing during assembly. This can lead to assembly errors or shaking during use, causing the display panel and through-hole to malalign. The pattern on the display panel will deviate relative to the through-hole, especially the outer frame pattern. For example, when the through-hole is circular, the outer frame pattern should be a ring-shaped pattern coaxially aligned with the through-hole and located circumferentially inside it. However, any deviation of the outer frame pattern relative to the through-hole will be very noticeable to the user, affecting the display effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a display structure and an air conditioner to solve the problem that errors in display box assembly or shaking during use cause the display panel and through holes to not be fully aligned, resulting in deviations in the pattern on the display panel relative to the through holes, thus affecting the display effect.

[0004] According to the embodiments of this utility model, the following technical solution is adopted:

[0005] The display structure includes a display box, an electronic control component installed inside the display box, and a light-transmitting component. The electronic control component is used to display a light source through circuitry. The light-transmitting component includes a display sticker and a light-transmitting plate. The display sticker has a first light-transmitting area, which is used to transmit the light source displayed by the electronic control component. The light-transmitting plate has a second light-transmitting area. The light-transmitting plate is used to be positioned outside the display sticker and connected to the housing of the air conditioner. The shape of the second light-transmitting area is the same as that of the first light-transmitting area. The projection of the second light-transmitting area toward the first light-transmitting area is completely located within the first light-transmitting area, and the area of ​​the second light-transmitting area is smaller than that of the first light-transmitting area.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] In this solution, by connecting the light-transmitting plate to the air conditioner housing, the position of the light-transmitting plate will not change. Even if there are assembly errors in the display box or it shakes during use, as long as it does not exceed a reasonable range, since the area of ​​the second light-transmitting area is smaller than the area of ​​the first light-transmitting area, the projection of the second light-transmitting area can be located within the first light-transmitting area. Therefore, the pattern observed by the user through the light-transmitting plate will not change and will not affect the display effect of the pattern.

[0008] Furthermore, the electronic control assembly includes a control circuit board snapped into the display box and a display component electrically connected to the control circuit board, the display component being used to display the light source.

[0009] Furthermore, the light-transmitting component also includes a limiting shell installed inside the display box, and a light guide channel for the light source of the power control component is opened inside the limiting shell.

[0010] Furthermore, a light guide column is provided within the light guide channel.

[0011] According to embodiments of this utility model, the following technical solutions are also adopted:

[0012] An air conditioner includes a housing and a display structure mounted on the housing, wherein the display box is detachably connected to the housing; the housing has a through hole for a light-transmitting plate to be exposed.

[0013] Furthermore, a positioning plate for circumferential positioning of the display box is fixed on the housing, and a locking block is provided on the positioning plate. A slot for engaging with the locking block is provided on the outer wall of the display box.

[0014] Furthermore, the card block includes a snap-fit ​​part and a positioning part. The positioning part includes a first inclined surface for guiding the positioning block into the card slot, and the snap-fit ​​part is used to snap into the card slot.

[0015] Furthermore, the side wall of the display box is provided with a second inclined surface, and the slot is opened on the second inclined surface, which is parallel to the first inclined surface.

[0016] Furthermore, multiple card blocks are provided, all located below the display box; the top of the display box and the housing are bolted together.

[0017] Furthermore, the through hole is a stepped hole, and the light-transmitting plate includes a protrusion that fits into the stepped hole. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0030] like Figure 2As shown, the display structure includes a display box 3, an electronic control component installed inside the display box 3, and a light-transmitting component. The electronic control component is used to display the light source through circuitry. Specifically, the electronic control component includes a control circuit board 4 snapped into the display box 3 and a display element electrically connected to the control circuit board 4. The display element is used to display the light source. The display element can be conventional LED, OLED, microLED, etc., according to existing technology. Depending on the actual usage requirements, a constant current drive can be set between the circuits of the control circuit board 4 and the display element. Taking LED as an example, controlling the LED to emit light through the control circuit board 4 is existing technology, and its connection and assembly methods are all conventional means. In this embodiment, as long as the LED can be used as a light source to emit light, it is sufficient. In actual use, if it is necessary to design multiple groups of LEDs in different areas so that the LEDs in different areas can be selected to emit light according to different control requirements of the control circuit, it can also be designed according to actual needs. This application does not make any improvements to this, nor will it elaborate on it.

[0031] The light-transmitting components include a display sticker 8 and a light-transmitting plate 9, combined with Figure 4 As shown, the display sticker 8 has a first light-transmitting area 12, which is used to transmit the light source displayed by the electronic control component. The display sticker 8 can be made of ordinary sticker. Except for the first light-transmitting area 12, the other areas can be selected to be light-transmitting as needed, so that the light source emitted by the display can be selectively transmitted. Of course, the display sticker 8 can also be made of LED backlight reflective paper with uniform light effect in the prior art, or paper of appropriate material can be selected according to other needs. The display sticker 8 can be directly pasted on the outside of the display, or it can be pasted through other connecting structures set on the control circuit board 4 (for example, connecting blocks are designed around the control circuit board 4 for pasting the display sticker 8), as long as the first light-transmitting area 12 can transmit the required light source.

[0032] Combination Figure 3 As shown, the light-transmitting plate 9 has a second light-transmitting area 11. The light-transmitting plate 9 is used to be positioned outside the display sticker 8 and connected to the panel 7 on the housing 1 of the air conditioner (in combination). Figure 1 As shown), during actual assembly, the light-transmitting plate 9 and the display sticker 8 are not connected. Therefore, when the light-transmitting plate 9 is connected to the housing 1 of the air conditioner, the light-transmitting plate 9 will not be affected regardless of whether there is an assembly error in the display sticker 8 during the assembly of the display box 3 or whether it shakes during use.

[0033] The shape of the second light-transmitting area 11 is the same as that of the first light-transmitting area 12. The projection of the second light-transmitting area 11 onto the first light-transmitting area 12 is completely within the first light-transmitting area 12, and the area of ​​the second light-transmitting area 11 is smaller than the area of ​​the first light-transmitting area 12. Figure 5As shown, taking the first light-transmitting area 12 and the second light-transmitting area 11 as examples where both are annular, the outer diameter of the second light-transmitting area 11 is smaller than the outer diameter of the first light-transmitting area 12, and the inner diameter of the second light-transmitting area 11 is larger than the inner diameter of the first light-transmitting area 12. That is, both the inner and outer sides of the second light-transmitting area 11 are located within the first light-transmitting area 12. Therefore, as long as it is within a reasonable range, regardless of whether the first light-transmitting area 12 deviates, the annular pattern displayed through the second light-transmitting area 11 will not change. Of course, depending on actual needs, the first light-transmitting area 12 and the second light-transmitting area 11 can have other shapes (such as square, elliptical, or other irregular shapes), as long as the above requirements are met.

[0034] In addition, display patterns 14 can be set on the display sticker 8 according to actual usage needs. The display patterns 14 are light-transmitting, such as switch symbols, air conditioning mode symbols, temperature, etc. Correspondingly, pattern display areas 13 are also set on the light-transmitting plate 9 for light transmission. Figure 3 The pattern display area 13 shown is a whole area, directly exposing the pattern 14. Compared to the outer ring, which is easily visible when off-center from the air conditioner housing 1, the pattern 14 is not noticeable even with small deviations. Therefore, this design is acceptable. Of course, the pattern display area 13 can also be designed similarly to the second light-transmitting area 11, so that it is completely within the range of the pattern 14, which can further improve the display effect. Both options can be chosen according to actual needs.

[0035] In another embodiment of this utility model, combined with Figure 9 As shown, to ensure the flatness of the display sticker 8, the light-transmitting component also includes a limiting shell 5 installed inside the display box 3. The limiting shell 5 has a light guide channel 21. Specifically, the limiting shell 5 can be directly fixed inside the display box 3, so that the electronic control components are also located inside the limiting shell 5. The limiting shell 5 can also be fixed to the control circuit board 4, as long as the display component is located inside the limiting shell 5. In actual design, the shape design of the light guide channel 21 guides the light source, allowing it to be emitted from the light guide channel 21 and projected onto the display sticker 8. By attaching the display sticker 8 to the end face of the limiting shell 5, the display sticker 8 is flattened, and the first light-transmitting area 12 corresponds to the light guide channel 21.

[0036] by Figure 10 As shown in the example, when a circular pattern is required, the limiting shell 5 can be designed as an outer shell and a mounting block located inside the outer shell, so that the gap between the outer shell and the mounting block forms a circular light guide channel 21. In actual design process, Figure 10 The shaded area shown (i.e. the mounting block) can also be designed with other desired patterns for hollowing out, as needed, for example, based on the display pattern 14.

[0037] In another embodiment of this utility model, a light guide post 6 is provided within the light guide channel 21. The light guide post 6 can be snapped into or adhered to the light guide channel 21. The light guide post 6 can be made of a light-transmitting material, such as glass or optical-grade acrylic sheet. The light guide post 6 achieves a certain effect of uniformly converging light. In addition, when a circular pattern is required, the light guide post 6 is located within the circular light guide channel 21, which can also serve to connect the inside and outside of the limiting shell 5, making it easier to install the limiting shell 5 within the display box 3. This ensures that the mounting block does not contact the control circuit board 4, avoiding interference with the use of the electronic control components.

[0038] In another embodiment of this utility model, such as Figure 1 , Figure 6 , Figure 7 As shown, an air conditioner is also disclosed, including a housing 1 and a display structure 2 mounted on the housing 1. The display structure 2 is selected from the display structure 2 in any of the above embodiments. The display box 3 is detachably connected to the housing 1. Specifically, the housing 1 includes a panel 7, and the display structure 2 is mounted on the panel 7. A positioning plate 19 for circumferential positioning of the display box 3 is fixed on the housing 1. The positioning plate 19 is provided with a locking block 15. The outer wall of the display box 3 is provided with a locking groove 20 for engaging with the locking block 15. In this embodiment, in order to ensure that the display box 3 has room for movement after assembly, the positioning plate 19 and the display box 3 do not contact each other circumferentially, and only serve the function of initially positioning the assembly position of the display box 3.

[0039] The specific engagement method between the display box 3 and the locking block 15 is as follows: The locking block 15 includes a locking part 18 and a positioning part 17. The positioning part 17 includes a first inclined surface for guiding the positioning block into the locking slot 20. The locking part 18 is used to engage with the locking slot 20. The side wall of the display box 3 is provided with a second inclined surface 16. The locking slot 20 is opened on the second inclined surface 16. The second inclined surface 16 is parallel to the first inclined surface. During assembly, the second inclined surface 16 on the display box 3 is inserted along the first inclined surface, so that the locking part 18 can be inserted into the locking slot 20. In actual design, for ease of assembly, multiple locking blocks 15 are provided, all located below the display box 3. The top of the display box 3 is bolted to the housing 1. Therefore, when assembling the display box 3, it is only necessary to insert the lower part of the display box 3 along the first inclined surface, so that the locking slot 20 and the locking block 15 engage, and then the top of the display box 3 is bolted to the housing 1.

[0040] Combination Figure 2 , Figure 8 As shown, the housing 1 has a through hole 10 for the light-transmitting plate 9 to be exposed. Specifically, the through hole 10 is opened on the panel 7. The through hole 10 is a stepped hole. The light-transmitting plate 9 includes a protrusion 22 that is stuck in the stepped hole. After the light-transmitting plate 9 is stuck in the through hole 10, the light-transmitting plate 9 can be glued to the panel 7 (i.e., in the stepped hole), further reducing the shaking of the light-transmitting plate 9.
