[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] It should be noted that in the prior art, capacitive touch screen technology works by utilizing the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin glass protective layer. The interlayer ITO coating serves as the working surface. Four electrodes are drawn out from the four corners. The inner layer ITO is a shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the existence of the human body electric field, a coupling capacitor is formed between the user and the touch screen surface. For high-frequency current, the capacitor is a direct conductor, so the finger absorbs a very small current from the contact point. This current flows out from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position of the touch point by accurately calculating the ratio of these four currents. The above is the working principle of the capacitive touch screen. However, household appliances need to be provided with operation buttons for users to operate. In the prior art, mechanical buttons or knobs are generally provided to turn the appliances on and off, adjust gears, and so on. In addition to the mechanical type, there are also some touch screen control methods. Generally, the touch screen is directly embedded in the appliance for user operation. However, with this arrangement, the touch screen is exposed to the outside and is easily impacted or scratched. Therefore, the touch screen can be set inside the appliance and protected by a glass panel without affecting the user's viewing of the operation. However, with this arrangement, water may condense inside the glass panel in some usage scenarios, especially for range hoods. When in use, the temperature difference is large and there is a lot of water vapor. A water film is easily formed between the touch screen panel and the glass panel. The water film can cause touch failure, thereby causing a malfunction. Therefore, it is necessary to prevent the formation of a water film to reduce the risk of a malfunction.

[0032] Reference Figures 1 to 5 According to the first aspect of the utility model, a waterproof film ITO touch screen control box includes a box body 100 and an ITO touch film panel 200. The box body 100 includes a side frame member 110. A protrusion 111 is provided at the front end of the side frame member 110. The protrusion 111 is used to abut against an outer panel 300. The ITO touch film panel 200 is arranged at the front end of the side frame member 110, and there is a height difference between the front end of the protrusion 111 and the surface of the ITO touch film panel 200. The protrusion 111 has at least one notch 112. The outer panel 300, the protrusion 111 and the ITO touch film panel 200 are enclosed to form a cavity 310. The notch 112 allows the cavity 310 to communicate with the outside. The raised portion 111 on the side frame 110 can provide a cavity 310 between the ITO touch film panel 200 and the outer panel 300, and the notch 112 set on the raised portion 111 can connect the cavity 310 with the outside. Even if water condenses on the outer panel 300 under the temperature difference, it is difficult to form a water film with the ITO touch film panel 200, and the internal water vapor can also evaporate from the notch 112, which can reduce the occurrence of touch failure of the ITO touch screen.

[0033] Specifically, the box body 100 can be set by injection molding, various electrical components such as circuit boards can be set inside the box body 100, and the ITO touch film panel 200 is set on the box body 100, and the box body 100 can be square-shaped, and the front end of the side frame 110 can be provided with a protrusion 111, and the protrusion 111 can form an installation position on the end of the side frame 110, and the ITO touch film panel 200 can be set on the position. After installation, there is a height difference between the protrusion 111 and the ITO touch film panel 200, that is, the protrusion 111 can be raised relative to the ITO touch film panel 200, so when it is connected to the electrical appliance During installation, the outer panel 300 on the appliance can only abut against the raised portion 111, and there is a gap between the raised portion 111 and the ITO touch film panel 200, and the raised portion 111 can be provided with a notch 112, so that there is a through hole connected to the cavity between the raised portion 111 and the outer panel 300. During use, under the influence of the temperature difference, the inner wall of the outer panel 300 condenses into water. Due to the existence of the gap, the ITO touch film panel 200 and the outer panel 300 will not form a water film, and the provided notch 112 can facilitate the dissipation of internal water vapor to further reduce the generation of water film, thereby reducing the occurrence of touch failure.

[0034] Reference Figures 2 to 4 In some embodiments of the present invention, the protrusion 111 is arranged along the outer contour of the side frame 110, and two notches 112 are arranged, and the notches 112 are respectively located at the upper and lower side walls of the side frame 110. This facilitates the flow of water vapor, further inhibits the generation of water film, and further reduces the occurrence of touch failure.

[0035] Specifically, the raised portion 111 can match the shape of the side frame member 110, and the notch 112 can be set at two positions on the upper and lower side walls, so that the cavity can form convection, which is convenient for the circulation of water vapor and further inhibits the formation of water film. In addition, the notches 112 set up above and below are not easy to accumulate water vapor. Even if there is accumulated water, it can be discharged from the lower notch 112, and the water vapor can be easily discharged from the upper notch 112.

[0036] It should be noted that the position of the notch 112 is not limited to the above embodiment, and other embodiments may also be adopted. For example, the notch 112 may also be set at the left and right side walls, or three or more notches may be set as long as water vapor can flow through.

[0037] Reference Figure 2 In some embodiments of the present invention, the upper and lower notches 112 are arranged opposite to each other. Specifically, the notches 112 can be arranged in alignment to increase the convection intensity and further inhibit the formation of water film.

[0038] In some embodiments of the present invention, the height difference between the protrusion 111 and the ITO touch film panel 200 is 0.3mm-0.5mm. Specifically, the gap between the protrusion 111 and the ITO touch film panel 200 can be set to 0.4mm, which does not affect touch control and also allows a gap for water vapor to evaporate.

[0039] Reference Figures 2 to 5 In some embodiments of the present invention, a support member 400 is further included. The support member 400 is disposed between the ITO touch film panel 200 and the outer panel 300 , and the support member 400 is disposed flush with the raised portion 111 .

[0040] Specifically, the ITO touch film panel 200 can be set to a rectangular shape, and the ITO touch film panel 200 can be deformed. In order to maintain the gap between the outer panel 300 and the ITO touch film panel 200, the spacing can be maintained by setting a support member 400, and the support member 400 can be set in an area where touch is not required to avoid affecting normal touch operations. The support member 400 can maintain a gap between the ITO touch film panel 200 and the outer panel 300 to further inhibit the formation of a water film.

[0041] Reference Figure 2 In some embodiments of the present invention, the support member 400 is annular or polygonal. Specifically, the support member 400 can be set to be annular, and the annular support member 400 can be set in the middle of the ITO touch film panel 200 to provide a beautiful visual effect, and the annular support member 400 can be set through the notch 112 so that the cavity in the support member 400 can be connected to the outside.

[0042] It is understandable that the support member 400 may also be configured to be square in shape, with a round hole or a square hole in the middle, and the specific shape is not specifically limited.

[0043] It should be noted that the ITO touch screen panel is provided with a display unit, and the circuit board inside the box body 100 can be provided with an information light group that displays various information parameters, and the light group can control the light beads therein to form different information, and the side frame 110 can also be provided with a transmission hollow part, which can transmit the light emitted by the information light group to the display unit to provide information for the user to view, and the annular support member 400 can be arranged to enclose the display unit, that is, the display unit is arranged in the middle of the support member 400, and the display unit is located in the annular support member 400, which can make the appearance of the touch part more beautiful.

[0044] Reference Figure 2In some embodiments of the present invention, a plurality of reinforcing members 113 are provided between the inner side walls of the side frame member 110, and the reinforcing members 113 are arranged at intervals. Specifically, the reinforcing members 113 can be integrally injection-molded with the box body 100, and the reinforcing members 113 can be provided between the two inner side walls of the long side of the side frame member 110, which can improve the overall strength of the side frame member 110.

[0045] It should be noted that the reinforcement member 113 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the reinforcement member 113 may also be arranged between two inner side walls of the short side of the side frame member 110 at intervals.

[0046] Reference Figure 2 In some embodiments of the present invention, the box body 100 further includes a bottom cover 120, which is detachably connected to the bottom of the side frame member 110. Specifically, the bottom cover 120 and the side frame member 110 can be connected by a snap-fit ​​structure, that is, a plurality of snaps can be provided on the bottom cover 120, and a snap groove corresponding to the snaps can be provided on the side frame member 110, and the snap groove can be snap-fitted to the snap groove. By providing the bottom cover 120, it is possible to facilitate the assembly of the components inside the box body 100, and various components can be installed on the side frame member 110 first, and then the bottom cover 120 can be installed to complete the overall assembly.

[0047] In some embodiments of the present invention, the ITO touch film panel 200 is connected to the front end of the side frame 110 by adhesive. Specifically, the ITO touch screen panel has low strength, and the adhesive connection with the frame can protect the ITO touch screen panel and avoid damage during installation.

[0048] It should be noted that the installation of the ITO touch screen panel is not limited to the above embodiment, and other embodiments may also be adopted. For example, the ITO touch screen panel may also be installed by snap-fitting with the frame.
