[0039] Compared with the prior art, the main advantages of the present invention are as follows:

[0040] (1) The display component structure is optimized to make full use of the internal space of the display component; the light-emitting element is set on the side wall of the mounting port, and the display panel is set on the front side of the panel; the light guide is set between the light-emitting element and the display panel, and the light guide has an incident surface and an exit surface, and a display film is set on the exit surface; when the light-emitting element emits light, the light emitted by the light-emitting element can be transmitted to the display film under the action of the light guide and pass through the light-transmitting area to be displayed on the display area; the area of ​​the light-transmitting area and the display area is increased, the display is eye-catching, the display effect is improved, and the user can see the display content and know the detergent liquid level in time;

[0041] (2) The light-emitting element is set on the top wall of the mounting port, and the light guide body is set inside the mounting cavity. The direction of the emission surface is the same as the direction of the opening, and the incident surface faces the light-emitting element. The wiring of the light-emitting element is convenient to install, and the display area is large. This solves the problem of complex wiring and safety of the light-emitting element when it is set inside the handle, and solves the problem of small area of ​​light-transmitting area caused by large space occupation when the light-emitting element is set inside the handle.

[0042] (3) The liquid level detector detects the liquid level in the main box and accurately and conspicuously displays the liquid level of the washing liquid by controlling the light emission parameters of the light emission element in the liquid level light emission element group.

Detailed Implementation

[0058] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0061] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0062] In the existing technology, due to the poor interaction between the washing machine and the user and the unreasonable structural design of the display device, the pattern for displaying the detergent level is small, not eye-catching enough, and has a poor display effect, making it impossible to see the display content when the ambient light is low.

[0063] This invention adds a display module to the existing detergent dispenser, proposing a clothing treatment device including a panel, a detergent dispenser, and a display component. The detergent dispenser includes a main body, which is push-in and pull-out through an installation port on the rear side of the panel. The display component is located at the installation port and includes a light-emitting element, a display panel, a light guide, and a display film. The light-emitting element is located on the side wall of the installation port, and the display panel is located on the front side of the panel. The light guide is located between the light-emitting element and the display panel and forms an incident surface and an exit surface. The display film covers the exit surface and forms a light-transmitting area. When the light-emitting element emits light, the light emitted by the light-emitting element can be propagated to the display film by the light guide and then passed through the light-transmitting area to be displayed on the display panel.

[0064] The display component structure has been optimized to make full use of its internal space; the light-transmitting area of ​​the display film and the display area of ​​the display panel have been increased, making the display more eye-catching and improving the display effect, so that users can clearly see the display content and know the detergent level in time.

[0065] <Clothing Processing Equipment>

[0066] like Figures 1a to 6As shown, this embodiment provides a garment processing device, including a panel 11, a detergent dispenser 2, and a display component; the panel 11 has a mounting opening 111, which connects the front and rear sides of the panel 11; the detergent dispenser 2 includes a main body 21, which is disposed on the rear side of the panel 11 and can be pushed in and pulled out through the mounting opening 111; specifically, the mounting opening 111 is formed on the left side of the panel 11, and the cross-sectional structure of the mounting opening 111 is adapted to the cross-sectional structure of the main body 21; a panel decorative panel 12 is disposed on the right side of the panel 11; and a display component is disposed on the rear side of the panel 11. The device includes an installation box, with the main box 21 housed within it. The main box 21 has a storage cavity for storing detergent and fabric softener. The main box 21 is fixed to the panel 11 via a first locking structure. Specifically, the first locking structure 131 includes a lock body and a lock hook. The lock body is located on one of the panel 11 and the main box 21, and the lock hook is located on the other. When the lock body and lock hook are engaged, the main box 21 is fixed within the installation box. When the lock body and lock hook are separated, the main box 21 can be pushed into or pulled out of the installation box.

[0067] The display component is located at the mounting port 111 and includes:

[0068] The light-emitting element 31 and the display panel 34 are provided. The light-emitting element 31 is disposed on the side wall of the mounting port 111, and the display panel 34 is disposed on the front side of the panel 11 and the display panel 34 forms a display area.

[0069] A light guide 32 is disposed between the light-emitting element 31 and the display panel 34. The light guide 32 has an incident surface 3221 on the side near the light-emitting element 31 and an exit surface 3211 on the side near the display panel 34.

[0070] Display film 33 covers the emission surface 3211 and has a light-transmitting area; the position of the light-transmitting area corresponds to the position of the display area; specifically, display film 33 is a color filter;

[0071] When the light-emitting element 31 emits light, the light emitted by the light-emitting element 31 can be propagated to the display film 33 under the action of the light guide 32, and then pass through the light-transmitting area to be displayed on the display area, where a pattern can be displayed. Specifically, the light emitted by the light-emitting element 31 enters the light guide 32 through the incident surface 3221, then propagates out of the light guide 32 through the exit surface 3211, and reaches the display film 33, and then passes through the light-transmitting area to be displayed on the display area. That is, the display component structure is optimized, the internal space of the display component is fully utilized, the position of the light-emitting element 31 is adjusted, and the direction of light propagation emitted by the light-emitting element 31 is changed by the light guide 32, increasing the area of ​​the light-transmitting area and the display area, making the display more eye-catching, improving the display effect, solving the problem of small area of ​​the light-transmitting area and display area and inconspicuous display caused by unreasonable structural design of the display component, and solving the problem of low brightness of the display area causing users to be unable to see the display content in dark ambient light.

[0072] To address the problem of insufficient light flux captured and propagated due to unreasonable structural dimensions of the incident surface 3221 and the exit surface 3211, this embodiment proposes that the incident surface 3221 be an arc-shaped surface, convex in a direction away from the light-emitting element 31; and the exit surface 3211 be a plane, with an area larger than that of the incident surface 3221. This allows for the capture of more light emitted by the light-emitting element and ensures that the propagated light is parallel, thereby improving the display effect and enhancing the user experience.

[0073] Furthermore, the light guide 32 also includes a refractive surface 3212, which is located between the incident surface 3221 and the exit surface 3211. The refractive surface 3212 is planar, and its area is larger than that of the incident surface 3221 and the exit surface 3211. This allows more light to enter the light guide 32 and propagate out through the exit surface 3211 under the action of the refractive surface 3212, thereby increasing the display brightness and display area.

[0074] To address the problem that the unreasonable structural design of the light guide 32 results in low light flux capture and propagation, this embodiment proposes that the light guide 32 includes a light guide body 321 and an incident portion 322, with the volume of the light guide body 321 being larger than the volume of the incident portion 322; an exit surface 3211 is formed on the front side of the light guide body 321, and a refractive surface 3212 is formed on the rear side of the light guide body 321, with the refractive surface 3212 being inclined relative to the exit surface 3211; the incident portion 322 is formed at one end of the light guide body 321, and an incident surface 3221 is formed at the end of the incident portion 322 away from the light guide body 321;

[0075] The light-emitting element 31 is disposed on the top wall 112 of the mounting port 111, and the incident part 322 is formed on the top of the light guide body 321 and is embedded in the through hole 2213; the refractive surface 3212 is located below the incident surface 3221 and behind the exit surface 3211; the light emitted by the light-emitting element 31 propagates downward and enters the incident part 322 through the incident surface 3221, and then propagates to the refractive surface 3212. Under the refraction of the refractive surface 3212, the light propagates towards the exit surface 3211.

[0076] Specifically, the incident part 322 is an elliptical cylindrical structure.

[0077] To address the issue of inconspicuous display and poor effect caused by the small area of ​​the light-transmitting and display areas, this embodiment proposes that the detergent box 2 also includes a handle 22, which is located on the front side of the main box body 21 and forms a mounting cavity 2211; an opening 2212 communicating with the mounting cavity 2211 is formed on the front side of the mounting cavity 2211, and a display panel 34 is covered at the opening 2212; a through hole 2213 communicating with the mounting cavity 2211 is formed on the side wall of the mounting cavity 2211 near the light-emitting element 31; specifically, the handle is mounted on the main box body 21 by a second locking structure 132, which includes an elephant trunk lock;

[0078] The light guide body 321 is set inside the mounting cavity 2211, and the orientation of the emitting surface 3211 is the same as that of the opening 2212; the incident part 322 is set inside the through hole 2213 and the incident surface 3221 faces the light-emitting element 31; the light-emitting element and wiring do not occupy space, and the wiring is easy to install, which can increase the volume of the light guide 32, thereby increasing the light flux and light intensity, and improving the display effect; it solves the problem of complex and unsafe wiring of the light-emitting element 31 when it is set inside the handle 22, and solves the problem of small light-transmitting area caused by large space occupation when the light-emitting element 31 is set inside the handle 22.

[0079] Furthermore, the handle 22 includes a handle frame 221 and a handle side plate 222. The handle frame 221 is disposed in the mounting opening 111 and the handle frame 221 forms a mounting cavity 2211. The handle side plate 222 is disposed on the handle frame 221 and the handle side plate 222 is located on the front side of the panel 11. Specifically, the handle side plate 222 is arranged around the handle frame 221 and the handle side plate 222 is close to the opening 2212.

[0080] Panel 11 is mounted on handle side panel 222 and closes opening 2212.

[0081] To address the issue of fixing the light-emitting element 31, this embodiment proposes that the display assembly further includes a mounting plate 35, on which the light-emitting element 31 is disposed; a focusing hole 113 is formed on the top wall 112 of the mounting port 111, the mounting plate 35 is disposed on the light-incident side of the focusing hole 113, the light-emitting element 31 is disposed inside the focusing hole 113, and the position of the light-emitting side of the focusing hole 113 corresponds to the position of the through hole 2213;

[0082] When the light-emitting element 31 is emitting light, the light emitted by the light-emitting element 31 can be propagated to the incident surface 3221 under the action of the focusing hole 113.

[0083] Furthermore, the display panel 34 is a display decorative panel, and the display panel 34 is made of a semi-transparent black material; that is, it can transmit light when there is light inside, and appears black when there is no light; in the absence of light, the display panel 34 covers the internal components of the handle 22.

[0084] To address the issue of unclear liquid level display, this embodiment proposes a display component including a liquid level light-emitting element group 361. The liquid level light-emitting element group 361 has multiple spaced-apart light-emitting elements 31, and is used to display the liquid level in the main container 21. The garment processing equipment also includes a liquid level detector, which is installed inside the main container 21 and used to detect the liquid level in the main container 21. The liquid level detector and the light-emitting elements 31 of the liquid level light-emitting element group 361 are electrically connected.

[0085] When the main box 21 contains washing liquid, the light emission parameters of the light emission element 31 in the liquid level light emission element group 361 correspond to the liquid level of the main box 21.

[0086] The luminescence parameters include at least one of the following: luminescence quantity, luminescence color, and luminescence brightness.

[0087] Furthermore, the display component also includes an alert light-emitting element group 361, which is electrically connected to the level sensor;

[0088] When the liquid level in the main box 21 is lower than the preset liquid level, the light-emitting element 31 in the reminder light-emitting element group 361 will be flashing to remind the user to add washing liquid;

[0089] In summary, the liquid level detector detects the liquid level in the main housing 21 and accurately and conspicuously displays the liquid level by controlling the luminous parameters of the luminous element 31 in the liquid level luminous element group 361. It also controls the luminous element 31 in the reminder luminous element group 361 to be in a flashing state, promptly reminding the user to add liquid. This solves the problems of existing washing machines being unable to display the liquid level or having an unclear display, and also solves the problem of the automatic dispensing button and the reminder button being integrated together in existing washing machines, making it difficult for users to distinguish between them.

[0090] In this embodiment, three light-emitting elements, three light guides, and three display films are provided, and the light-emitting elements 31, the light guides 32, and the display films 33 are arranged in a one-to-one correspondence. The main box 21 forms a first storage cavity and a second storage cavity. The first storage cavity is used to store fabric softener, and the second storage cavity is used to store detergent. The light-emitting elements include a fabric softener level light-emitting element group 361, a reminder light-emitting element group 361, and a detergent level light-emitting element group 361 arranged in sequence. The fabric softener level light-emitting element group 361 is used to display the level of fabric softener, the reminder light-emitting element group 361 is used to remind the user to add detergent, and the detergent level light-emitting element group 361 is used to display the level of detergent.

[0091] <Control Methods>

[0092] like Figure 7 As shown, this embodiment also provides a control method for a garment processing device, wherein the garment processing device is any of the garment processing devices described above; the detergent dispenser 2 is located behind the panel 11 and before the garment processing device runs the washing program, and the control method includes:

[0093] S1. Obtain the current liquid level of the main box 21;

[0094] S2. Compare the current liquid level with the preset liquid level;

[0095] S3. Based on the comparison between the current liquid level and the preset liquid level, control the light emission parameters of the light emission element 31 in the liquid level light emission element group 361 and / or remind the light emission status of the light emission element 31 in the light emission element group 361.

[0096] The light emission states include continuous light emission and flashing.

[0097] Furthermore, S3 includes:

[0098] S31. When the current liquid level is higher than the preset liquid level, control the light-emitting element 31 to be bright and determine the liquid level range of the current liquid level.

[0099] S32. Determine the number and color of light emitted by the light-emitting element 31 based on the current liquid level range.

[0100] Specifically, the liquid level luminous element group 361 has multiple luminous elements 31 arranged from bottom to top in a first row, a second row, a third row, and a fourth row, with each row including at least one luminous element 31. When the current liquid level is in the first liquid level range, the first row of luminous elements emits light, and the light color is green.
