[0039] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This disclosure provides a control panel component. Combined with... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the control panel assembly includes a housing 1, a display cover 2, a lamp holder assembly 3, and a seal 4. The housing 1 has a receiving groove 11. The display cover 2 covers the opening of the receiving groove 11 and is connected to the housing 1. The lamp holder assembly 3 is located within the receiving groove 11 and is connected to the display cover 2. The seal 4 is located between the lamp holder assembly 3 and the display cover 2.

[0042] The control panel assembly provided in this embodiment of the present disclosure, the lamp holder assembly 3, the display cover 2 and the seal 4 form a force-bearing system. The force exerted by the seal 4 on the display cover 2 is the internal force of the force-bearing system. This force will not act between the display cover 2 and the housing 1, thereby reducing the possibility that the display cover 2 may be lifted by the seal 4.

[0043] The aforementioned "lamp holder assembly 3 is connected to the display cover plate 2, and the sealing element 4 is located between the lamp holder assembly 3 and the display cover plate 2" means that: the display cover plate 2 has a first connecting area and a first non-connecting area, the lamp holder assembly 3 has a second connecting area and a second non-connecting area, the second connecting area is fixedly connected to the first connecting area, and the sealing element 4 is located between the first non-connecting area and the second non-connecting area. Under the constraint of the first connecting area and the second connecting area, the sealing element 4 is clamped.

[0044] In this way, it can be ensured that in the force system formed by the lamp holder assembly 3, the display cover 2 and the seal 4, the force exerted by the seal 4 on the display cover 2 is the internal force of the force system. This force mainly acts between the display cover 2 and the lamp holder assembly 3, and will not act between the display cover 2 and the housing 1, thereby reducing the possibility that the display cover 2 will be lifted by the seal 4.

[0045] Optionally, the display cover 2 is a transparent plastic cover, which is used to protect the internal structure of the housing 1 and to allow the user to see the display of the internal structure of the housing 1.

[0046] Optionally, the seal 4 is a sealing foam.

[0047] Optionally, the seal 4 is annular and located at the edge of the upper surface of the lamp holder assembly 3, thereby sealing the gap between the lamp holder assembly 3 and the display cover 2.

[0048] Combination Figure 1 , Figure 3As shown, in some embodiments, the lamp holder assembly 3 includes a lamp holder 31 and a circuit board 32. The lamp holder 31 is connected to the display cover plate 2, and the interior of the lamp holder 31 has a mounting groove 311, the bottom of which has multiple light-transmitting holes 3111. The circuit board 32 is fixed in the mounting groove 311, and the circuit board 32 has multiple light-emitting elements, which are placed one-to-one in the multiple light-transmitting holes 3111.

[0049] In this way, the light beam can be emitted through the light-emitting elements on the circuit board 32 to achieve the lighting effect of the lamp holder assembly 3. Moreover, multiple light-emitting elements are placed one-to-one in multiple light-transmitting holes 3111, which can illuminate different areas respectively. Thus, the display effect of different areas can be changed by changing the brightness of different areas.

[0050] In some embodiments, the control panel assembly further includes a touch film, and the lamp holder assembly 3 further includes a color filter. The color filter and the touch film are respectively located between the display cover 2 and the lamp holder 31, with the touch film located on the side of the color filter closer to the display cover 2. The touch film is used to trigger an electrical signal when the display cover 2 is pressed.

[0051] In this way, the light beam emitted by the light-emitting element on the circuit board 32 can pass through the light-transmitting hole 3111 and shine on the display frame, thereby illuminating the color film on the lamp holder 31 to display the image on the color film.

[0052] like Figure 3 As shown, in some embodiments, the display cover 2 has a first snap-fit ​​portion 201, and the lamp holder assembly 3 has a second snap-fit ​​portion 301, which engages with the first snap-fit ​​portion 201.

[0053] Thus, in the force-bearing system formed by the lamp holder assembly 3, the display cover 2, and the seal 4, the force exerted by the seal 4 on the display cover 2 will act on the first latching portion 201 and the second latching portion 301. This allows the first latching portion 201 and the second latching portion 301 to bear the reaction force of the seal 4, preventing this reaction force from acting between the display cover 2 and the housing 1, thereby reducing the possibility of the display cover 2 being lifted by the seal 4. Furthermore, by employing this method, under the constraint of the first latching portion 201 and the second latching portion 301, the lamp holder assembly 3 and the display cover 2 can clamp the seal 4 tightly, thereby ensuring that the seal 4 has a good sealing effect.

[0054] like Figure 3 As shown, in some embodiments, one of the first latching portion 201 and the second latching portion 301 is a protrusion and the other is a clearance hole.

[0055] Thus, when the protrusion enters the clearance hole, it can engage with the clearance hole, thereby enabling the first engagement part 201 and the second engagement part 301 to engage in a relatively simple manner, thereby improving the convenience of engagement between the display cover 2 and the lamp holder assembly 3.

[0056] Optionally, in the snapping direction of the first snap-fit ​​portion 201 and the second snap-fit ​​portion 301, the size of the protrusion is smaller than the diameter of the clearance hole.

[0057] This ensures that the protrusion can smoothly enter the clearance hole and engage with it.

[0058] Furthermore, under the reaction of the seal 4, the protrusion will abut against the wall of the clearance hole, thereby preventing relative shaking of the display cover 2 or the lamp holder assembly 3.

[0059] like Figure 3 As shown, in some embodiments, the display cover 2 includes a connected main body 21 and an extension 22. The main body 21 is connected to the housing 1, and the extension 22 protrudes from the surface of the main body 21 near the bottom of the receiving groove 11, surrounding at least a portion of the sidewall of the lamp holder assembly 3. A first snap-fit ​​portion 201 is located on the extension 22, and a second snap-fit ​​portion 301 is located on the sidewall of the lamp holder assembly 3.

[0060] Thus, during the process of moving the lamp holder assembly 3 into the space enclosed by the extension 22, the first engaging portion 201 located on the extension 22 can engage with the second engaging portion 301 located on the side wall of the lamp holder assembly 3. This eliminates the need for direct control of the first and second engaging portions 201, allowing for a more convenient engagement. Furthermore, the extension 22 guides the engagement of the first and second engaging portions 201, further enhancing the ease of engagement.

[0061] Optionally, the clearance hole is located in the extension 22, and the protrusion is located on the side wall of the lamp holder assembly 3.

[0062] like Figure 3 As shown, in some embodiments, the extension 22 includes a first extension 221 and a second extension 222 opposite to each other. The first extension 221 and the second extension 222 are located on both sides of the lamp holder assembly 3 and each has at least one first snap-fit ​​portion 201.

[0063] In this way, the display cover 2 can be engaged with the lamp holder assembly 3 on both sides, so that the reaction force of the sealing element 4 can act on both sides of the lamp holder assembly 3 respectively. That is, the display cover 2 can be constrained on both sides of the lamp holder assembly 3. Compared with the scheme where the first engagement part 201 is located on one side of the lamp holder assembly 3, the possibility of the display cover 2 or the lamp holder assembly 3 lifting off locally due to uneven force can be greatly reduced.

[0064] Furthermore, when the first extension 221 and the second extension 222 each have a plurality of first latching portions 201, the plurality of first latching portions 201 can each bear a portion of the reaction force of the elastic member, thereby reducing the force on a single first latching portion 201 and a second latching portion 301, and thus reducing the possibility of damage to a single first latching portion 201 and a second latching portion 301.

[0065] In other embodiments, the display cover 2 is glued to the lamp holder assembly 3.

[0066] Thus, the display cover 2 and the lamp holder assembly 3 are fixedly connected by adhesive. This connection process is relatively convenient and allows the display cover 2 to have a simpler structure, thereby greatly reducing the production difficulty of the display cover 2 and improving the production efficiency of the display cover 2.

[0067] like Figure 2 As shown, in some embodiments, the housing 1 has a stepped structure 12 located at the opening of the receiving groove 11 and surrounding the receiving groove 11, and the upper surface of the stepped structure 12 is bonded to the display cover 2.

[0068] Thus, by setting the stepped structure 12, the adhesive layer between the display cover 2 and the housing 1 can be hidden, preventing the adhesive layer between the display cover 2 and the housing 1 from being exposed, thereby greatly improving the aesthetics of the control panel assembly. In addition, the stepped structure 12 can also be used to position the adhesive layer, thereby greatly improving the convenience of bonding the housing 1 and the display cover 2.

[0069] Combination Figure 1 , Figure 2 As shown, in some embodiments, the upper surface of the stepped structure 12 and the adhesive layer of the display cover 2 are cured and formed by liquid adhesive. The upper surface of the stepped structure 12 has a plurality of protrusions 121, which are located at the middle of the upper surface of the stepped structure 12 in the width direction. The plurality of protrusions 121 are arranged at intervals to form adhesive overflow notches.

[0070] Thus, by utilizing the protrusions 121, the liquid adhesive can accumulate to a certain height, ensuring that the cured adhesive has sufficient thickness for stable bonding between the housing 1 and the display cover 2. Furthermore, during the connection process between the display cover 2 and the housing 1, the display cover 2 compresses the liquid adhesive on the stepped portion, allowing it to flow out through the overflow notch. This releases the pressure of the liquid adhesive, ensuring smooth bonding between the stepped structure 12 and the display cover 2. Additionally, since the multiple protrusions 121 are located at the midpoint of the upper surface of the stepped structure 12 in the width direction, even if the liquid adhesive flows out from the overflow notch, it will flow to another part of the upper surface of the stepped structure 12, thereby reducing the possibility of liquid adhesive flowing into the receiving groove 11.

[0071] In related technologies, when the adhesive between the display cover and the housing is cured and molded using liquid adhesive, the force exerted by the sealant on the liquid adhesive will act on the liquid adhesive, which will result in the liquid adhesive requiring a longer curing time.

[0072] In contrast, by adopting the technical solution provided in this disclosure embodiment, the reaction force of the seal 4 will not act on the liquid adhesive between the display cover plate 2 and the housing 1, thereby greatly reducing the time required for the liquid adhesive to cure and form.

[0073] like Figure 2 As shown, in some embodiments, there is a gap between the bottom of the lamp holder assembly 3 and the bottom of the receiving groove 11.

[0074] In this way, the bottom of the lamp holder assembly 3 can be prevented from contacting the bottom of the receiving groove 11, so that the lamp holder assembly 3 can enter the receiving groove 11 and ensure the smooth installation of the lamp holder assembly 3.

[0075] Furthermore, taking the aforementioned scheme where "one of the first latching portion 201 and the second latching portion 301 is a protrusion and the other is a clearance hole, and the size of the protrusion is smaller than the diameter of the clearance hole in the latching direction of the first latching portion 201 and the second latching portion 301" as an example, in this process, if there is no gap between the bottom of the lamp holder assembly 3 and the bottom of the receiving groove 11, the lamp holder assembly 3 may be squeezed by the bottom of the receiving groove 11, thereby causing the seal 4 to be squeezed by the lamp holder assembly 3, preventing the protrusion from abutting against the wall of the clearance hole. Consequently, the protrusion and the clearance hole cannot withstand the reaction force of the seal 4. At this time, the reaction force of the seal 4 will act on the connection between the display cover 2 and the housing 1, and lift the display cover 2. Thus, by creating a gap between the bottom of the lamp holder assembly 3 and the bottom of the receiving groove 11, this situation can be avoided, thereby greatly reducing the possibility of the display cover 2 being lifted.

[0076] Optionally, the spacing value is greater than 0.5 mm, and can be, for example, but not limited to, 1 mm.

[0077] Combination Figure 1 , Figure 2 As shown, the bottom of the receiving groove 11 has a through hole. The control panel assembly also includes a rear cover 5 and a seal 4. The bottom of the housing 1 has a sealing groove 13, which is located at the edge of the through hole. The rear cover 5 is snapped into the housing 1 and partially inserted into the sealing groove 13. The sealing gasket 6 is located in the sealing groove 13 and between the rear cover 5 and the housing 1.

[0078] Thus, the through-hole facilitates the routing of circuitry or other functional arrangements within the housing 1, while the sealing gasket 6 seals the rear cover 5 against the housing 1, reducing the possibility of liquid entering the housing 1 through the rear cover 5.

[0079] The following is a method for assembling control panel components according to an embodiment of this disclosure:

[0080] Step 1: Apply the touch film to the back of the display cover 2 to obtain the cover assembly;

[0081] Step 2: Fix the lamp holder 31 in the mounting groove 311 and attach the colored film to the upper surface of the lamp holder 31 to obtain the lamp holder assembly 3;

[0082] Step 3: Assemble the lamp holder assembly 3 and the display cover plate 2 assembly to obtain the pre-assembled assembly;

[0083] Step 4: Glue the pre-assembled components to the housing 1;

[0084] Step 5: Attach the sealing gasket 6 to the back cover 5 to obtain the back cover 5 assembly;

[0085] Step 6: Attach the back cover 5 component to the housing 1 to obtain the control panel component.

[0086] In the assembly process described above, steps 1, 2, and 5 can be pre-assembled first, followed by steps 3, 4, and 6, in order to improve the assembly efficiency of the control panel components.

[0087] Based on the same concept, this disclosure also provides a household appliance, which includes the control panel component provided above.

[0088] Optionally, the household appliance may be, for example, but not limited to, a washing machine or a refrigerator, and this disclosure does not limit this. The control panel assembly may be installed in, embedded in, contact with, fixed to, temporarily fixed to, supported in, coupled to, or located in the housing of the household appliance, and this disclosure does not limit this.
