Description

Display device and washing machine

Technical Field

The invention belongs to the field of household appliances, and particularly relates to a display device and a washing machine.

Background

In the display device using a disk film in the prior art, a small lamp hole and a display lamp arranged in the lamp hole are used for displaying, and when a user selects a certain program, the lamp hole corresponding to the program is lighted, but a corresponding key, a character or an icon cannot be lighted.

Fig. 1 and 2 show a specific structure of a display device in the prior art, in which an operation panel 1 and a display panel support 2 are fixed by a claw 3, a lamp hole 4 is formed on the operation panel 1, and a display lamp 5 capable of lighting the lamp hole 4 is disposed at a corresponding position on the display panel support 2. The operation panel 1 is also provided with a key 6 which can be pressed and triggered, and a disk film 7 is pasted on the upper surface of the operation panel 1, and characters or icons for prompting a user are printed on the disk film 7 through screen printing. The display lamp 5 can only illuminate the lamp hole 4, and the user can know the currently selected program through the prompt of the characters or icons at the corresponding positions of the lamp hole 4 and the disk film 7, but cannot directly illuminate the corresponding characters or icons.

If it is desired to illuminate the text or icons on the operation panel 1, holes need to be formed in the operation panel 1 at corresponding positions so that light can pass through the holes. However, the area of the opening corresponding to the text or icon is significantly larger than the area of the lamp hole 4, while the disc film 7 is generally made of a PET film or the like, the thickness is about 0.25mm, and the disc film 7 is easily collapsed due to the large area of the opening below, which affects the flatness and is not beautiful enough. Meanwhile, the increase of the area of the opening also requires greater illumination intensity, and when the characters or icons at a certain opening are illuminated, the light source illuminating the opening may also radiate to the periphery, so that the openings around the opening are illuminated, and the adjacent characters or icons are partially illuminated. This may cause the user to be unable to clearly identify the actually illuminated text or icon, and may even mislead the user, which may affect the user experience.

In view of the above, the present invention is particularly proposed.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

Example one

As shown in fig. 3 to 7, the display device of the present embodiment includes a display panel holder 300 and an operation panel 100, wherein a plurality of light troughs 301 are disposed on the display panel holder 300, and each light trough 301 has a display lamp capable of being independently lighted. The operation panel 100 is mounted on the display panel holder 300, and the operation panel 100 has a plurality of display regions 103 corresponding to the light grooves 301.

The display device further includes a light blocking structure disposed between the operation panel 100 and the display panel holder 300, the light blocking structure being located between adjacent display regions 103.

In the above-described scheme, the light blocking structure located between the adjacent display regions 103 can prevent crosstalk between the adjacent display regions 103. Specifically, when any one of the display regions 103 is illuminated by the display lamp in the light trough 301 below, due to the blocking effect of the light blocking structure, the light illuminating the display region 103 will not spread around to illuminate the adjacent display region 103, thereby avoiding the phenomenon that the adjacent display region 103 is locally illuminated, and further preventing the user from being unable to clearly identify the display region 103 that is actually illuminated, which leads to misoperation.

In this embodiment, a disk film (not shown) is attached to the upper surface of the operation panel 100, display icons are provided on the disk film corresponding to the display regions 103, and the disk film is illuminated from below by a display lamp in the lamp house 301, so that the corresponding display icons are lit up and displayed.

The light blocking structure in the present embodiment is a light blocking rib 110 provided between the operation panel 100 and the display panel holder 300. Specifically, the light blocking structure is a light blocking rib 110 formed to extend from the lower surface of the operation panel 100 toward the fascia support 300, and an extending end of the light blocking rib 110 abuts against the fascia support 300 between the adjacent light troughs 301.

In another aspect of this embodiment, the light blocking structure may further be a light blocking rib formed by extending from the upper surface of the display panel bracket to the operation panel, and an extending end of the light blocking rib abuts against the operation panel between adjacent display regions.

In the above solution, the gap between the operation panel 100 and the display panel holder 300 between two adjacent display regions 103 is completely blocked by the light blocking rib 110, and there is almost no gap through which light can pass, so that the crosstalk prevention effect is better.

In a further aspect of this embodiment, each display area 103 on the operation panel 100 is provided with a through hole 101, and the display device further includes a lamp cover 200 mounted on the display panel bracket 300. The lamp cover 200 has a light-transmitting protrusion 210 corresponding to the plurality of display regions 103, and the light-transmitting protrusion 210 is fittingly installed in the through hole 101. The lamp shade 200 is provided with an isolation hole 220, and the light blocking rib 110 is arranged in the isolation hole 220 in a penetrating manner.

In the above solution, the operation panel 100 is made of an opaque material, and only the display area 103 is through which light can pass, so that the upper disk film is not irradiated by light in the area except the display area 103, and only the area corresponding to the display area 103 can be illuminated, so that the difference between the brightness of the displayed icon on the disk film and the surrounding area is larger, and the display is more obvious.

In this embodiment, light can be irradiated on the disk film by opening the through hole 101 at the display region 103. But at the same time, the portion of the disk membrane at the through hole 101 may collapse significantly due to lack of support, which may affect the aesthetic appearance. Meanwhile, the disc membrane is damaged easily if the collapsed position of the disc membrane is subjected to a large external force.

In order to solve the above problem, in the present embodiment, the lamp cover 200 having the light-transmitting protrusions 210 is mounted on the display panel bracket 300, and the light-transmitting protrusions 210 are made of a transparent material, are mounted in the through holes 101 in a matching manner, do not affect the light passing therethrough, and can also support the disc film at the position.

In a preferred embodiment of the present invention, the upper surface of the light-transmitting protrusion 210 is flush with the upper surface of the operation panel 100. The transparent protrusions 210 fill up the through holes 101 of the operation panel 100, so that the surface on which the disk film is adhered is formed as a flat plane, and the disk film can be smoothly adhered to the upper surface of the operation panel 100. On one hand, a flat display surface can be formed, the attractiveness of the display device is improved, and on the other hand, the situation that the surface of the display device is easy to be cleaned due to the fact that the display device is prone to dust deposition is avoided.

In a further aspect of this embodiment, the lamp cover 200 has a certain extension length and a certain width, and the light-transmitting protrusions 210 are distributed in at least two rows along the length direction of the lamp cover 200, and are distributed in at least two columns along the width direction of the lamp cover 200.

The isolation holes 220 include a first isolation hole 221 disposed between two adjacent columns of the light-transmissive protrusions 210, and a second isolation hole 222 disposed between two adjacent rows of the light-transmissive protrusions 210. The first isolation hole 221 is not communicated with the second isolation hole 222. The light blocking ribs 110 include first light blocking ribs 111 disposed through the first isolation holes 221, and second light blocking ribs 112 disposed through the second isolation holes 222.

In the above solution, the light-transmitting protrusions 210 are distributed in a matrix in both the length and width directions of the lamp cover 200. A first isolation hole 221 is disposed between the light-transmitting protrusions 210 in adjacent columns for the first light-blocking rib 111 that prevents light crosstalk between the light-transmitting protrusions 210 in the same row to pass through. A second isolation hole 222 is disposed between two adjacent rows of the light-transmitting protrusions 210, through which the second light-blocking rib 112 for preventing light crosstalk between the light-transmitting protrusions 210 in the same column passes.

As shown in fig. 4, in the present embodiment, the first isolation hole 221 and the second isolation hole 222 are not communicated, so that the situation that the lamp cover 200 is easily damaged due to an excessive influence on the strength of the lamp cover 200 caused by the arrangement of the isolation hole 220 is avoided.

Specifically, the display device of the present embodiment has twelve display regions 103, and correspondingly, twelve light-transmitting protrusions 210 are disposed on the lamp cover 200 and distributed in two rows and six columns. The middle part of the lampshade 200 is provided with an avoiding opening 201 for avoiding a digital display surface 302 arranged on the display panel bracket 300 in a protruding way. Three rows, namely six light-transmitting protrusions 210, are respectively arranged on the left side and the right side of the avoiding opening 201.

If the first isolation hole 221 and the second isolation hole 222 are disposed in a communicating manner, taking the light-transmitting protrusion 210 at the upper left corner in fig. 4 as an example, the periphery of the lower right corner is not connected to the periphery, and is easily bent when receiving an external force. Similarly, for the light-transmitting protrusion 210 adjacent to the right side thereof, only the upper edge is connected to the entire lamp cover 200, and the left side, the right side, and the lower side are not connected. When a certain external force is applied to a position close to the lower side of the light-transmitting protrusion 210, the light-transmitting protrusion is easily bent around the upper edge of the light-transmitting protrusion, and may even be directly broken when the external force is too large.

In the present embodiment, the first isolation hole 221 is not communicated with the second isolation hole 222, that is, the above situation does not exist, so that the lamp shade 200 is not easily damaged.

In a preferred embodiment of the present invention, the first isolation holes 221 between two adjacent columns of the light-transmitting protrusions 210 are communicated with each other, and the end of the second isolation hole 222 is spaced from the adjacent first isolation hole 221. Correspondingly, the first light blocking ribs 111 positioned between two adjacent rows of through holes 101 are sequentially connected end to form a whole, the second light blocking ribs 112 between two adjacent rows of through holes 101 are arranged between different first light blocking ribs 111, and the end parts of the second light blocking ribs 112 and the adjacent first light blocking ribs 111 are arranged at intervals.

In the above-described aspect, the first isolation holes 221, which correspond in position in the width direction of the lamp housing 200, communicate with each other, and the second isolation holes 222 are intermittently provided in the length direction of the lamp housing 200. Correspondingly, the first light blocking ribs 111 corresponding to the positions are continuously arranged, and the second light blocking ribs 112 are intermittently arranged. Compared with the scheme that the first isolation holes 221 and the second isolation holes 222 are both arranged intermittently, and the first light blocking ribs 111 and the second light blocking ribs 112 are also both arranged intermittently, the processing and assembling difficulty is reduced. Meanwhile, the first light blocking rib 111 is arranged on the lower surface of the operation panel 100, so that the strength of the operation panel 100 can be enhanced, and two purposes can be achieved.

In another scheme of this embodiment, the second isolation holes between two adjacent rows of light-transmitting protrusions may be communicated with each other, and an end of the first isolation hole is spaced from the adjacent second isolation hole. Correspondingly, a plurality of second light blocking ribs between two adjacent rows of through holes are sequentially connected end to form a whole, a first light blocking rib between two adjacent rows of through holes is arranged between different second light blocking ribs, and the end part of the first light blocking rib and the adjacent second light blocking rib are arranged at intervals.

In a further aspect of this embodiment, the lamp housing 200 is attached to a surface of the display panel holder 300 opposite to the display panel holder.

Preferably, the light-transmitting protrusions 210 are arranged in one-to-one correspondence with the lamp slots 301. That is, the light troughs 301 of the display panel holder 300 are arranged in one-to-one correspondence with the display regions 103 of the operation panel 100, and the display light in each light trough 301 illuminates a corresponding one of the display regions 103 of the operation panel 100 independently.

In the above scheme, lamp shade 200 lower surface and the laminating of display panel support 300 set up, and the light that the display lamp was played directly shines on lamp shade 200 in the exit of light trough 301, and the degree of diffusion takes place in the in-process that shines lamp shade 200 after having reduced light to the at utmost and having played light trough 301, has realized better string light effect with the cooperation of the muscle 110 that is in the light of being in the shade simultaneously.

In this embodiment, in order to reduce the processing difficulty and the manufacturing process, the light-blocking rib 110 extends from the lower surface of the operation panel 100 to abut against the display panel bracket 300, so as to prevent the possibility of light crosstalk inside the light-blocking cover 200, because the light-blocking cover 200 is made of a light-transmissive material by integral molding, that is, the light-blocking rib 200 is also transparent except for the light-transmissive protrusion 210.

In a further aspect of this embodiment, the surface of the display panel holder 300 is partially recessed to form a mounting groove 310, and the lamp housing 200 is disposed in the mounting groove 310.

Preferably, the surface of the lamp housing 200 facing the operation panel 100 is located at a region other than the light-transmitting protrusion 210, and is flush with a region of the surface of the display panel supporter 300 located outside the mounting groove 310.

In the above-mentioned solution, the upper surface of the display panel holder 300 is partially recessed to form the mounting groove 310, which is advantageous for positioning when the lamp housing 200 is mounted. After the lamp shade 200 is installed on the display panel support 300, the surface of the lamp shade 200 and the display panel support 300 are flush, when the operation panel 100 is further installed, the lamp shade 200 and the display panel support 300 support the operation panel 100 together, and the phenomenon that the middle area of the operation panel 100 is partially suspended to cause the structure of the display device to be unstable or the suspended part below the operation panel 100 is easily damaged by external force is avoided.

Further, one side of the mounting groove 310 is opened, and the lamp housing 200 is inserted into/drawn out of the mounting groove 310 through the opening. Since the lamp cover 200 is installed on the display panel supporter 300 in a drawing manner, the display panel supporter 300 cannot have a protrusion on the surface thereof, and the light blocking rib 110 can be only fixedly installed on the operation panel 100.

Preferably, the operation panel 100 is integrally formed with the light blocking rib 110. The subsequent manufacturing process of fixing the light blocking rib 110 on the operation panel 100 is omitted, and meanwhile, the position of the light blocking rib 110 on the operation panel 100 is more accurate, so that the processing difficulty of the operation panel 100 is reduced, and the manufacturing process is reduced.

In this embodiment, the height of the light blocking rib 110 is the same as the thickness of the portion of the lamp cover 200 between the two light-transmitting protrusions 210, as shown in fig. 6, when the light blocking rib 110 is inserted into the isolation hole 220, it is flush with the surface of the lamp cover 200 facing away from the operation panel 100. Thus, the lamp cover 200 is attached to the display panel bracket 300, and the light blocking rib 110 abuts against the display panel bracket 300.

In the present embodiment, the specific assembly structure of the lamp housing 200 and the display panel holder 300 is as follows.

As shown in fig. 4 and 7, the open both sides of the mounting groove 310 are provided with insertion grooves 311 extending along the insertion/extraction direction of the lamp housing 200, the lamp housing 200 is provided with insertion parts 230, and the insertion parts 230 are inserted into the insertion grooves 311 to realize the connection between the lamp housing 200 and the display panel bracket 300.

The left and right side surfaces of the mounting groove 310 are provided with insertion grooves 311, and the lower sides of the insertion grooves 311 are flush with the bottom surface of the mounting groove 310. The left side and the right side of the lamp cover 200 are respectively provided with the inserting parts 230, and the thickness of the inserting parts 230 is smaller than that of the middle area of the lamp cover 200. The insertion part 230 is inserted into the insertion groove 311, and is held and limited by the upper and lower side surfaces of the insertion groove 311, and the lamp housing 200 cannot be removed from the upper side of the mounting groove 310, thereby being fixed to the display panel bracket 300. No additional fixing is required between the lamp housing 200 and the display panel holder 300, and when the display lamp in the lamp slot 301 is out of order, the lamp housing 200 is easily removed from the display panel holder 300, so that the display lamp in the lamp slot 301 can be replaced.

The display device of the present embodiment is a display device using a key touch, and a plurality of keys 303 are further disposed on the display panel holder 300. The operation panel 100 is provided with a plurality of key holes 102 corresponding to the keys 303 one by one, and the keys 303 are installed in the key holes 102 in a matching manner, and are flush with the upper surface of the operation panel 100 or slightly higher than the upper surface of the operation panel 100.

The display device of the embodiment further includes a potting box 400 disposed below the display panel bracket 300, and the display panel bracket 300 is installed in the potting box 400 and is fixedly connected to the potting box 400. The display panel support 300 is provided with a control circuit board, display lamps in the lamp grooves 301, and keys 303 on the display panel support 300 are all connected with the control circuit board, and the control circuit board is also connected with a power supply line and/or a signal transmission line. When the display panel bracket 300 is installed in the potting box 400, the control circuit board is located inside the potting box 400, and sealant is injected into the potting box 400 for sealing, so that particularly when the display device is used for washing equipment such as a washing machine and a dishwasher, the damage of an internal circuit caused by water seepage of the potting box 400 can be prevented.

In the display device of the embodiment, the light blocking ribs 110 are disposed between the operation panel 100 and the display panel holder 300, and the light blocking ribs 110 block the light emitted from each light trough 301 in the range of the corresponding display area 103, so as to prevent crosstalk interference from occurring in the display device, which causes the adjacent display areas 103 to be illuminated. The through hole 101 for light transmission on the operation panel 100 is filled by the arrangement of the lamp cover 200, so that the disk film can be smoothly adhered to the upper surface of the operation panel 100 without collapsing. The lamp cover 200 is installed on the display panel bracket 300 in a drawing mode, so that the installation and disassembly operations are simple, the display device is convenient to maintain, and especially, the lamp cover 200 is taken down to replace the display lamp when the display lamp fails.
