DETAILED DESCRIPTION

[0024] The application will be described in detail below with reference to specific embodiments shown in the attached drawings. However, these embodiments do not limit the application, and any changes in structure, method, or function made by those skilled in the art based on these embodiments are included in the protection scope of the application.

[0025] It should be understood that the terms such as "upper", "above", "lower", "below" and the like used herein to indicate spatial relative positions are used for the purpose of convenient description to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms can be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0026] The refrigeration equipment of the embodiment can be a refrigerator, a freezer, a vertical refrigeration cabinet, a wine cabinet, etc. The following embodiments can be described by taking a refrigerator as an example. The refrigeration equipment includes a cabinet, a liner 2000 arranged in the cabinet, a door frame surrounded by a connection between the liner 2000 and the cabinet, a refrigeration cavity 220 surrounded by the liner 2000, an opening of the refrigeration cavity 220 surrounded by the door frame, and a door body covering the opening. The refrigeration equipment further includes a partition assembly 1000 fixedly connected with the liner 2000. The liner 2000 includes a pair of liner 2000 side walls arranged left and right. The partition assembly 1000 is fixed between the liner 2000 side walls, as shown in Figure 1 The partition assembly 1000 can divide the refrigeration cavity 220 into two cavities 220, i.e., a refrigeration chamber S1 and a freezing chamber S2.

[0027] To clearly express the positions and directions described in the embodiment, in the embodiment, the partition assembly 1000 can divide the refrigeration cavity 220 into two cavities 220 arranged vertically. The division of the upper cavity 220 and the lower cavity 220 can also refer to the direction of gravity. At this time, the refrigerator is vertically placed on the ground. The partition assembly 1000 can be fixed horizontally with the liner 2000. The direction of the door body relative to the liner 2000 is front. The opposite direction is defined as back. For example, the user faces the opening from front to back. The left hand direction of the user is left. The right hand direction of the user is right. The horizontal is only a kind of name definition and is not limited to the horizontal in the physical sense. Of course, in the preferred embodiment, the horizontal can be parallel to the horizontal plane in physics.

[0028] In addition, the partition assembly 1000 can be divided into upper and lower spaces, left and right spaces, or conventional refrigeration spaces or multifunctional cold and hot cabinets. The present application takes the partition assembly 1000 for dividing the upper and lower spaces and applied in the refrigerator as an example for detailed description. The freezing chamber S2 is arranged below the refrigeration chamber S1.

[0029] The partition assembly 1000 of the embodiment includes a main partition 200, a sub-partition 300, and a display module 100. The main partition 200 includes an upper partition 70 and a lower partition. A display groove 71 is arranged above the upper partition 70. The display module 100 is fixedly connected in the display groove 71. A main cavity 220 is surrounded by the lower partition below the upper partition 70 and the lower partition. A heat preservation member is arranged in the main cavity 220. The heat preservation member can be a foaming material, as shown in Figure 1 and 2 .

[0030] This configuration, from bottom to top, is: freezer compartment S2 - lower partition - insulation component - upper partition 70 - display module 100 - refrigerator compartment S1. In other words, the display module 100 is separated from the freezer compartment S2 by an insulation component, preventing the display module 100 from directly contacting the very low temperature of the freezer compartment S2, and exposing it only to the refrigerator compartment S1. This allows the display module 100 to be positioned on the partition assembly 1000 while also preventing excessively low temperatures from affecting the display module 100.

[0031] The main partition 200 is fixedly connected to the inner liner 2000 of the refrigeration equipment, and the secondary partition 300 is fixed in the accommodating space by the limiting part. The partition assembly 1000 has a first state and a second state. In the first state, the secondary partition 300 is accommodated in the accommodating space and the secondary partition 300 simultaneously closes the upper opening and the lower opening. In the second state, the secondary partition 300 is moved out of the accommodating space.

[0032] The display module 100 is positioned in front of the sub-partition 300. This gives the partition assembly 1000 more functions, allowing it to be both installed / removed and used for display. It also facilitates intelligent interaction between the user and the refrigeration equipment. The installation / removal of the sub-partition 300 does not affect the display of the display module 100.

[0033] like Figure 3 As shown, the display module 100 includes a panel support 10, a display support 20, a display panel 40 fixedly connected to the panel support 10, a display film 50, and a display plate 30 coupled to the display support 20. Specifically:

[0034] The panel bracket 10 includes a slot 11, in which the display panel 30 is embedded. The size of the slot 11 can be the same as that of the display panel 30, or the shape of the slot 11 can be the same as the outer contour of the display bracket 20.

[0035] The display panel 40 includes several display areas, which are arranged upwards and exposed above the refrigerator compartment S1. The display panel 40 has a touch area and / or a display area. In this embodiment, the display panel 40 can be made of ultra-white glass and is fixed to the panel support 10 with double-sided adhesive 60, forming a glass support assembly. The double-sided adhesive 60 has an exposure hole 61, through which light emitted from the lower display panel 30 passes and is used for touch sensing.

[0036] The display film 50 is attached to the display panel 40. The display film 50 includes several markings corresponding to the display areas, and the markings are aligned with the openings 31. The display film 50 is attached to the display panel 40 and aligned with the slot 11. The display film 50 has several markings corresponding to the touch area and / or display area. The display film 50 can be a colored sticker, which displays the operating parameters of the refrigerator or the options for adjusting the operating status, such as refrigeration mode, quick cooling, energy saving, temperature, preservation, defrosting, and network connection. The display unit on the display panel 30 emits light to illuminate the corresponding markings, or the touch sensor aligns with these markings. Both the panel bracket 10 and the display panel 30 are attached to the display film 50.

[0037] The display bracket 20 includes several light-emitting cavities 210. The light-emitting cavities 210 themselves do not emit light. The light from the display panel 30 is irradiated into the light-emitting cavities 210, and then scattered, reflected, refracted and emitted.

[0038] The display panel 30 includes a light-emitting unit 32 and an opening 31 corresponding to the light-emitting cavity 210. The opening 31 is aligned with the display area, and the light-emitting unit 32 emits light downwards. The display panel 30 may also include a touch-sensing part corresponding to the touch area. Each light-emitting unit 32 corresponds to each light-emitting cavity 210, and the touch-sensing part is aligned with the mark on the display film 50 corresponding to the touch area.

[0039] The light-emitting cavity 210 and the opening 31 are filled with a light-transmitting filler. The light emitted by the light-emitting unit 32 passes through the light-transmitting filler and is directed to the opening 31. At least part of the light emitted by the light-emitting unit 32 passes through the light-emitting cavity 210 and is directed upwards to make the light illuminating the display area uniform.

[0040] Although the light-emitting unit 32 is relatively close to the icon on the display film 50, the light is diffused within the light-transmitting filler because it relies on reflection and the sealing colloid is a light-transmitting milky white colloid, resulting in uniform illumination of the icon on the display film 50.

[0041] Furthermore, the light-emitting unit 32 emits light in the opposite direction to the display direction of the display panel 40. This avoids the problem of localized overbrightness caused by direct point light source irradiation of the display film 50. In this way, the light reaching the display panel 40 can only be light reflected or scattered by the light-emitting cavity 210 and diffused through the light-transmitting filler.

[0042] The light-emitting unit 32 is disposed at the edge of the opening 31, such as Figure 7 As shown, each light-emitting cavity 210 corresponds to two or four light-emitting units 32, and every two light-emitting units 32 are positioned opposite each other in the opening 31. This makes the illumination more uniform and avoids local areas being too bright or too dark.

[0043] Further, the display film 50 has the same size as the display panel 40, so that the alignment of the display film 50 to the display panel 40 is avoided, and the production is faster.

[0044] The application will be further described below Figure 6 The display support 20 will be further described in detail from the perspective of the display support 20:

[0045] The display support 20 comprises a support side wall 22, a cavity 220 surrounded by the support side wall 22, a plurality of light-emitting matching units arranged in the cavity 220, each of the light-emitting matching units comprising an inner wall 21, a light-emitting cavity 210 surrounded by the inner wall 21, a light-emitting port communicating with the light-emitting cavity 210, a first glue inlet hole 211 and a second glue inlet hole 23, the inner wall 21 abutting against the display panel 30, the light-emitting port facing the opening 31, the first glue inlet hole 211 being away from the light-emitting port, and the second glue inlet hole 23 communicating with the cavity 220.

[0046] The light-emitting unit 32 can be an LED lamp bead, emitting a point light source. If the distance between the point light source and the display film 50 is too close, the display effect is locally too bright and other places are too dark. In the present application, the display film 50 is uniform in brightness when viewed from top to bottom, and the display effect is better.

[0047] As shown in Figure 4 and 5 , the shape of the slot 11 is consistent with the outer contour of the display support 20. In production, there can be a certain tolerance distance, for example, the gap between the display support 20 and the four sides of the slot 11 is about 0.2 mm. The gap is very small. After the display panel 30 is tightly attached to the display support 20, the glue is prevented from entering the inside of the display support 20 after the glue is poured, especially into the light-transmitting hole to affect the propagation of light, causing the problem of uneven display brightness.

[0048] At least part of the light-emitting cavity 210 corresponds to two first glue inlet holes 211, and the two glue inlet holes are arranged at two ends of the light-emitting cavity 210. Figure 5 As shown in , the glue is poured from two directions at the same time, which is more sufficient.

[0049] Figure 5 In addition, in , the two first glue inlet holes 211 correspond to different light-emitting cavities 210, and the two light-emitting cavities 210 are separated by the inner wall 21, so that the light in the two light-emitting cavities 210 does not affect each other, and the inner wall 21 is used for partitioning;

[0050] Figure 6 The display support 20 further comprises a plurality of third glue inlet holes 212 communicating with the cavity 220.As shown, the third glue inlet hole 212 does not directly fill the light-emitting cavity 210 with glue, but on the one hand, it can speed up the glue filling speed of the cavity 220, avoiding the slow glue filling speed of the first glue inlet hole 211, and on the other hand, it can observe the overall glue filling speed, avoiding the local position being too fast or too slow to adjust, and facilitating the discharge of internal gas during glue filling.

[0051] The third glue inlet hole 212 is more specifically located outside the light-emitting cavity 210, and is hollowed out as much as possible. The hollowed-out area can serve as the third glue inlet hole 212 and facilitate observation of whether the glue is fully filled after glue filling.

[0052] Through the first glue inlet hole 211, the second glue inlet hole 23 and the third glue inlet hole 212, the glue is fully filled in the cavity 220 during glue filling, especially in the light-emitting cavity 210, thereby stabilizing the light emission. Since the cavity 220 is filled with glue, the gap is blocked by the glue, avoiding the entry of water vapor into the display module 100, and the sealing is better.

[0053] The display panel 30 includes a circuit board and a plurality of touch sensing parts connected to the circuit board. Each touch sensing part is in contact with the display film 50. The touch sensing part can include a touch sensing capacitor disposed on the circuit board. The sensing capacitor does not need to be provided with a spring because the distance between the sensing capacitor and the display panel 40 is close enough. The touch sensing part corresponds to the identifier of the touch control area, and the opening 31 corresponds to the identifier of the display area. In this way, when the display film 50 corresponding to the touch control area is touched from the outside, touch control is realized.

[0054] The light-emitting cavity 210 filled with glue works normally as shown. Figure 7 After the light is irradiated downward, it is reflected and scattered to occupy a thinner space and achieve better display effect.

[0055] Further, the display support 20 includes a stepped part 221 disposed on the side wall. The side wall encloses the upper opening, and the stepped part 221 is disposed around the upper opening and is recessed in the thickness direction of the side wall. The display panel 30 is in contact with the stepped part 221, and the cross section of the upper opening matches the outer contour of the display panel 30.

[0056] During installation, the display panel 30 is first fixed with the display support 20, the display film 50 is pasted under the display panel 40, and then the display panel 40 is fixed with the panel support 10. The display support 20 is fixed with the panel support 10 from below, and then glue is filled to complete the installation of the entire display module 100.

[0057] Then, the display module 100 is connected with the display slot 71 in circuit:

[0058] The display groove 71 is provided with a connecting wire, and the display panel 30 comprises a lead wire, the connecting wire and the lead wire are directly connected, the direct connection is distinguished from the connection through a plug-in connector, since the plug-in connector has a certain height, occupies space, and when being installed, the display module 100 and the main partition plate 200 need to be stabilized, and then the plug-in of the plug-in connector can be performed, which is more troublesome; when the structure of the embodiment is used, when the display module 100 is installed in the factory, only one hand is needed to butt the lead wire, without the need of using two hands to butt the plug-in connector and then fixing by using a tape, so that the production efficiency is improved.

[0059] Then, the display module 100 is fixedly connected with the display groove 71.

[0060] The front side of the display groove 71 is provided with a plurality of first clamping portions 72, and the panel support 10 is provided with a second clamping portion 15 matched with the first clamping portion 72; the first clamping portion 72 and the second clamping portion 15 are both provided in an "L" shape, and the two "L" shaped clamping portions are clamped with each other.

[0061] The rear side of the display groove 71 is provided with a plurality of first matching portions 73, and the panel support 10 is provided with a second matching portion 17 matched with the first matching portion 73. The first matching portion 73 and the second matching portion 17 can both be holes, wherein the first matching portion 73 is provided with a thread, and a screw or a bolt is arranged to pass through the second matching portion 17 and the first matching portion 73 in sequence, so as to fix the display module 100.

[0062] In the installation process, the display module 100 is assembled first, then the second clamping portion 15 at the front end of the display module 100 is clamped with the first clamping portion 72 of the display groove 71, the relative fixation of the front end of the display module 100 and the display groove 71 is realized, then the display module 100 is turned over, the second matching portion 17 at the rear end of the display module 100 is also fixed with the display groove 71, so that the installation of the display module 100 on the partition plate assembly 1000 is completed.

[0063] In addition, the upper surface of the upper partition plate 70 which is not covered by the display module 100 is located in the same plane as the upper surface of the display panel 40. In this way, the integrality is better, and it is also convenient to place articles on the upper surface.

[0064] Compared with the prior art, the embodiment has the following beneficial effects:

[0065] The display module 100 does not directly irradiate the display area through the light of the light emitting unit 32, but utilizes the reflection of the light emitting cavity 210 and the diffusion of the light-transmitting filler to form scattered light, so as to make the light irradiated on the display area uniform. This structure has the advantages that on the one hand, the space size of the display module 100 is small, and the thickness is thin, so that the space occupation is greatly reduced; on the other hand, the sealing performance is good, since the inside is completely filled with the light-transmitting filler, so that water vapor cannot enter the inside, and the fog generated at low temperature is avoided.

[0066] It should be understood that although the present specification is described in terms of embodiments, not every embodiment exhibits every characteristic or exhibits the described implementation to the full extent.
