Description

Technical Field

[0001] The utility model relates to the technical field of household appliances with touch control functions, in particular to a touch control panel component for household appliances and a household appliance with the touch control panel component. Background Art

[0002] In recent years, glass panels have become popular in household appliances. Users can switch or adjust the glass panel by touching it directly. This is generally achieved by setting a touch control panel component behind the glass panel. For example, a color film control panel is one example. The color film can also be directly printed with prompt text or icons. In order to ensure touch sensitivity, the gap between the color film screen and the glass is required to be high. Most of the existing control panel installation technologies use a method of fixing the control panel on a mounting bracket with multiple screws to prevent local warping and other undesirable conditions such as poor touch. For example, the Chinese utility model "A disinfection cabinet display screen installation structure" with application number 201821453949.7 (authorization announcement number CN 209695885 U) discloses such an installation method. The disinfection cabinet display screen installation structure includes a panel and a display screen. The display screen is set behind the panel. The panel and the display screen are connected by a mounting plate and a mounting bracket fixed on the back of the panel. At least four screws need to be set between the mounting plate and the mounting bracket. The installation is more troublesome and the structure is more complicated.

[0003] In addition, since the color film control panel is thicker than the existing control panels, and the installation space for the control panel in household appliances is often limited, after the color film control panel is installed, the protruding electronic components on the back of the control panel are close to the outer casing of the household appliance. Therefore, once the outer casing is deformed during transportation, it is very likely to cause damage to the electronic components and even lead to the risk of leakage during use.

[0004] In addition, in order to ensure that the gap between the touch control panel and the glass panel is small enough, the most common method in the prior art is to bond the two together by applying glue between the two. The Chinese invention patent application "A panel assembly and a household appliance using the panel assembly" with application number 202211435447.2 (publication number CN116321828A) proposed by the applicant provides a technical solution in which an elastic member acts on the mounting frame, so that the mounting frame maintains a forward movement trend under the action of elastic force. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to propose a touch control panel assembly for household appliances which can effectively prevent the local warping of the touch control panel and improve the installation accuracy in view of the above technical status.

[0006] The second technical problem to be solved by the utility model is to provide a touch control panel assembly for household appliances which can effectively prevent the electronic components on the touch control panel from being damaged due to shell deformation.

[0007] The third technical problem to be solved by the present invention is to provide a household appliance using the above touch control panel assembly.

[0008] The technical solution adopted by the utility model to solve the first technical problem is: a touch control panel assembly for household appliances, comprising: a mounting frame and a touch control panel mounted thereon, characterized in that:

[0009] The installation frame is formed by an upper frame, a lower frame and a side frame and is in a side-mounted U-shape with a side opening, wherein the lower surface of the upper frame and the upper surface of the lower frame are respectively provided with left and right extending grooves at corresponding positions, and each groove extends to the edge of the side opening; and the front surfaces of the upper frame, the lower frame and the side frame are all on the same plane, which is recorded as the first plane;

[0010] The touch control panel has a touch panel on its front side, and convex ribs extending left and right are respectively provided at the positions corresponding to the grooves on the top and bottom sides, and each convex rib is respectively inserted into the corresponding groove from the lateral opening of the mounting frame until the side edge of the touch control panel abuts against the side frame;

[0011] Furthermore, the front surface of the touch panel is flush with the first plane, or the front surface of the touch panel is parallel to the first plane and the interval therebetween is less than 1 mm.

[0012] Since a continuous rib-groove mating method is used instead of a discrete screw fixing method, the touch control panel can be effectively prevented from being partially warped even without screws, which not only facilitates installation but also avoids deformation caused by screw tightening. It is also easier to accurately control the front surface of the touch panel to be flush with the mounting frame, extend forward or retract backward, thereby ensuring that the gap between the front surface of the touch panel and the glass panel to be installed is as small as possible.

[0013] In order to ensure that the front surface of the touch panel is as close to the glass panel as possible when the touch control panel assembly is bonded to the glass panel by gluing, the front surfaces of the upper and lower frames and the side frames are all provided with grooves and connected through to form a whole side-mounted U-shaped gluing groove, so that the gluing is more uniform; and considering the thickness of the glue itself after gluing, the front surface of the touch panel is preferably protruded forward from the first plane, and the interval between the two is 0.2 to 0.4 mm.

[0014] To further solve the second technical problem solved by the present invention, electronic components may be arranged on the back of the touch control panel, and a rear cover may be included, which is at least respectively engaged with the upper frame and the lower frame, and encloses the electronic components on the back of the touch control panel at its front side and leaves spaces between them.

[0015] The rear cover may also be partially recessed, and the electronic components on the back of the touch control panel are accommodated in the recessed portion, so that during installation, the portion of the rear cover that is not recessed can directly rest against the housing or other components of the household appliance, thereby allowing the entire touch control panel assembly to rest more firmly on the glass panel.

[0016] In order to further ensure the connection between the touch control board and the rear cover plate and facilitate installation, a first mounting lug protruding laterally outward can be provided at the rear cover plate at a position of the side U-shaped opening corresponding to the mounting frame. At the same time, the touch control board has a second mounting lug protruding laterally outward at a position corresponding to the first mounting lug of the rear cover plate, and the two mounting lugs are connected by screws.

[0017] In order to take into account both installation accuracy and processing convenience, at least one positioning column can be arranged at intervals on the upper and lower sides of the inner side of the side frame, and the side edge of the touch control panel is against the positioning column. In this way, it is only necessary to ensure (or trim) the flatness of the top end of the positioning column to control the installation accuracy, without ensuring (or trimming) the flatness of the entire inner side surface of the side frame.

[0018] The technical solution adopted by the utility model to solve the third technical problem is: a household appliance, characterized in that it includes a glass panel and the above-mentioned touch control panel assembly is installed on the back of the glass panel.

[0019] Compared with the prior art, the utility model has the advantages of replacing the discrete screw fixing method with a continuous rib-groove plug-in method, so that even without screws, the touch control panel can be effectively prevented from being partially warped, which is not only convenient for installation, but also avoids deformation caused by screw tightening, and it is also easier to accurately control the front surface of the touch panel to be flush with the mounting frame, extend forward or retract, thereby ensuring that after being installed on the glass panel, the front surface of the touch panel is as close to the glass panel as possible.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 to Figure 5 As shown in FIG. 1 , a preferred embodiment of the touch control panel assembly of the utility model is applied to a household appliance. In this embodiment, the household appliance is a disinfection cabinet. Figure 1 As shown, a glass panel 300 is provided on the upper part of the disinfection cabinet, and the touch panel control component is installed on the rear side of the glass panel 300 .

[0027] like Figure 5 As shown, the touch control panel assembly includes a mounting frame 100 , a rear cover plate 101 and a touch control panel 200 . The touch control panel 200 is mounted in the mounting frame 100 . The rear cover plate 101 is integrally connected to the mounting frame 100 and is located at the rear side of the mounting frame 100 .

[0028] like Figure 2 and Figure 4 As shown, the touch control panel 200 is provided with a touch pad on the front side, and convex ribs 201 extending left and right are provided at corresponding positions on the top and bottom sides respectively, and electronic components 203 are provided on the back side. The right side has a second mounting lug 202 protruding laterally outward and a color film control wiring 204 and a control line socket 205 arranged adjacent to the second mounting lug 202.

[0029] The installation frame 100 is formed by an upper frame 102, a lower frame 103 and a left side frame 104 and is as shown in FIG. Figure 3The right opening 108 is a side-mounted U-shape, and the position of the opening 108 is just opposite to the left frame 104. The lower surface of the upper frame 102 of the mounting frame 100 and the upper surface of the lower frame 103 are provided with grooves 105 corresponding to a convex rib 201 of the touch control panel 200, respectively. The grooves 105 extend left and right and extend all the way to the edge of the right opening 108, so that the convex rib 201 is inserted into the corresponding grooves 105 from the lateral opening 108 of the mounting frame 100, until the left side of the touch control panel 200 abuts against the left frame 104 of the mounting frame 100. In actual production, it is often easier to make a small plane with a higher flatness than to make a larger plane with a higher flatness using the same process. Therefore, at least one positioning column 107 can be arranged at intervals on the inner side of the left frame 104, and the side of the touch control panel 200 abuts against the positioning column 107. The number of positioning columns 107 can be selected according to needs. In this embodiment, there are two positioning columns 107. In addition, grooves are formed on the front surfaces of the upper frame 102, the lower frame 103 and the left side frame 104 and are connected to form a whole U-shaped glue groove 111 on the side. Silicone can be placed in the glue groove to make the glue coating more uniform.

[0030] The front surfaces of the upper frame 102, the lower frame 103, and the left side frame 104 are all on the same plane, which is referred to as the first plane 1S. The front surface 2S of the touch panel is flush with the first plane 1S, or the front surface 2S of the touch panel is parallel to the first plane 1S and the interval is less than 1 mm. Since the silica gel itself generally has a thickness of 0.3 to 0.5 mm, the distance that the front surface 2S of the touch panel protrudes forward from the first plane is set within 0.2 to 0.4 mm in this embodiment, preferably 0.3 mm in this embodiment, so that the gap between the glass panel 300 and the front surface 2S of the touch panel is within 0.3 mm.

[0031] The rear cover plate 101 is joined to the rear surface of the mounting frame 100, and is at least joined to the lower frame 103 of the upper frame 102, and in this embodiment, is also joined to the side frame 104. The rear cover plate 101 surrounds the electronic components 203 on the back of the touch control board 200 on its front side and leaves a gap between them. The rear cover plate 101 is partially recessed backwards, and the electronic components 203 on the back of the touch control board 200 are accommodated in the recessed backwards portion. The rear cover plate 101 has a first mounting lug 106 that protrudes laterally at the position corresponding to the side U-shaped opening 108 of the mounting frame 100. And the two mounting lugs are connected by screws.

[0032] The installation frame 100 of this embodiment is enclosed by an upper frame 102, a lower frame 103 and a left side frame 104, and the opening 108 faces the right side, but the installation frame 100 can also be enclosed by an upper frame 102, a lower frame 103 and a right side frame, and the opening faces the left side, and the remaining corresponding components can be axially symmetrically changed with the mid-vertical line of the installation frame 100 as the axis. The household appliances described in the utility model include but are not limited to range hoods, dishwashers, steamers, ovens, microwave ovens, refrigerators, disinfection cabinets, washing machines, water heaters, air conditioners, and combined appliances integrating at least two of the above.
