Description

Technical Field

[0001] The utility model shows an electromagnetic cooking device, belonging to the technical field of electromagnetic cooking devices. Background Art

[0002] With the development and promotion of the small household appliance industry, electromagnetic cooking devices are deeply loved by consumers because of their advantages such as easy portability and fast heating. Existing electromagnetic cooking devices include a base, an upper cover and a panel assembly. The upper cover has an operation panel, and users control the electromagnetic cooking device through the operation panel to meet cooking needs with multiple different functions.

[0003] In order to make the operation and observation of the operation panel more comfortable for the user, the operation panel in the prior art is tilted as a whole. The operation panel usually includes an operation interface, an operation mask and a display panel. The display panel is fixedly connected to the operation interface, and the operation interface has a display area and a button area for the user to observe and operate. The operation mask itself has an adhesive backing and is bonded to the operation interface through the adhesive backing. However, the bonding between the adhesive backing and the operation interface cannot be completely sealed, which may cause oil or sewage to penetrate between the operation mask and the operation interface. At the same time, since the operation panel is tilted as a whole, oil or sewage can easily slide down along the operation interface. When oil or sewage slides to the button or between two buttons, it can easily cause the button to be insensitive or even malfunction, thereby seriously affecting the user experience. Utility Model Content

[0004] The utility model aims to solve the problem that oil and water easily seep into the operating mask and the operating interface, which easily leads to key failure. For this purpose, an electromagnetic cooking device is provided, in which a water guide groove can guide liquid away from the operating interface to maintain the sensitivity of the keys.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An electromagnetic cooking device comprises a base, an upper cover and a panel assembly, wherein a display panel is arranged in the base, the upper cover has an operation interface arranged in an inclined manner, the display panel is fixed to the bottom of the operation interface, an operation mask is bonded to the surface of the operation interface, the operation interface has a plurality of buttons, a water guide groove is arranged on the operation interface, in the inclined direction of the operation interface, the water guide groove is at least partially located on the upper side of the buttons to prevent liquid from flowing into the buttons along the operation interface; a liquid outlet is arranged in the water guide groove, and the water guide groove guides liquid to leave the operation interface through the liquid outlet.

[0007] The beneficial effects of adopting the utility model are:

[0008] In the present utility model, a water guide groove is provided on the operation interface. Part of the water guide groove is located above the keys. When liquids such as oil or sewage slide down along the operation interface, the liquid above the keys will enter the water guide groove. The water guide groove can block liquids such as oil or sewage, effectively restricting the direct slide of liquids such as oil or sewage along the operation interface onto the keys, reducing the possibility of the keys malfunctioning due to the influence of liquids such as oil or sewage, and the water guide groove can effectively protect the keys, thereby enabling the keys to maintain a high sensitivity. Additionally, a liquid outlet hole is provided in the water guide groove. When liquids such as oil or sewage enter the water guide groove, the water guide groove can guide the liquid to leave the operation interface through the liquid outlet hole, thereby reducing the accumulation of liquid in the water guide groove, preventing the liquid from accumulating too much and overflowing the water guide groove, improving the protection ability of the water guide groove for the keys. At the same time, the water guide groove can continuously guide the liquid to leave the operation interface, thereby effectively extending the service life of the water guide groove and enabling the keys to maintain a high sensitivity.

[0009] Preferably, there is a water guide groove between two adjacent keys in the operation interface, and the water guide groove guides the liquid to flow from between the two keys to the liquid outlet hole. With the foregoing technical solution, having a water guide groove between two adjacent keys can prevent the liquid from being between the two keys and causing mutual influence between the two keys, reducing the possibility of the keys being insensitive or malfunctioning.

[0010] Preferably, there are water guide grooves on both sides of each key in the operation interface, and the water guide grooves guide the liquid to flow from both sides of the key to the liquid outlet hole. With the foregoing technical solution, having water guide grooves on both sides of the key can effectively prevent the liquid from spreading from the side of the key to the liquid area during the downward slide of the liquid along the operation interface, improving the protection effect of the water guide groove on the liquid.

[0011] Preferably, in the inclined direction of the operation interface, at least part of the water guide groove extends to the lower side of the key. The end of the water guide groove at the lower side of the key is the lower end, and the liquid outlet hole is at the lower end of the water guide groove. With the foregoing technical solution, the extension of the water guide groove to the lower side of the key can increase the volume of the water guide groove, thereby enabling the water guide groove to hold more liquid and reducing the possibility of the liquid overflowing the water guide groove. Additionally, after the liquid enters the water guide groove, it will flow along the water guide groove to the lower side of the key. Even if the liquid overflows the water guide groove, the overflowed liquid is still at the lower side of the key, reducing the possibility of the liquid flowing to the key, which helps to improve the protection effect of the water guide groove on the key.

[0012] Preferably, the lower end of the water guide groove has a bottom wall and a lower side wall. The bottom end of the lower side wall is connected to the lower end of the bottom wall, and the top end of the lower side wall extends to the operation interface. The liquid outlet hole is arranged on the lower side wall, and the liquid flows along the bottom wall towards the liquid outlet hole. With the above technical solution, the lower side wall is at the lowermost end of the water guide groove, which can increase the distance between the liquid outlet hole and the display board and reduce the possibility of liquid dripping onto the display board. In addition, after the liquid enters the water guide groove, it will flow along the water guide groove to the lower side wall, and setting the liquid outlet hole on the lower side wall can ensure that the liquid can flow out of the water guide groove through the liquid outlet hole and reduce the accumulation of liquid in the water guide groove.

[0013] Preferably, the water guide groove includes a first groove section and a second groove section that communicate with each other. In the inclined direction of the operation interface, the first groove section is on the upper side of the second groove section. The depth of the first groove section is less than that of the second groove section, and the lower side wall is at the end of the second groove section away from the first groove section. With the above technical solution, increasing the depth of the second groove section can further increase the height of the lower side wall, that is, increase the area of the liquid outlet hole, so that the liquid can flow out of the water guide groove through the liquid outlet hole faster and reduce the accumulation of liquid in the water guide groove. In addition, increasing the liquid outlet hole can also reduce the possibility of the liquid outlet hole being blocked, so that the liquid can flow smoothly through the liquid outlet hole. Secondly, increasing the depth of the second groove section can also increase the volume of the water guide groove, enabling the water guide groove to hold more liquid and reducing the possibility of liquid overflowing from the water guide groove.

[0014] Preferably, the lower end of the water guide groove has a bottom wall, and the liquid outlet hole is arranged on the bottom wall, and the liquid flows along the bottom wall towards the liquid outlet hole. With the above technical solution, after the liquid enters the water guide groove, it will flow along the bottom wall towards the lower end of the water guide groove, and setting the liquid outlet hole on the bottom wall at the lower end of the water guide groove can ensure that the liquid can flow out of the water guide groove through the liquid outlet hole and reduce the accumulation of liquid in the water guide groove.

[0015] Preferably, the projection position of the liquid outlet hole on the operation mask is below the projection position of the display board on the operation mask. With the above technical solution, in the inclined direction of the operation interface, the liquid outlet hole is below the display board, which can avoid the liquid directly dripping onto the display board after passing through the liquid outlet hole, reduce the influence of liquids such as oil or sewage on the display board, and provide effective guarantee for the normal operation of the display board.

[0016] Preferably, the notch of the water guide groove is formed on the operation interface, and the operation mask covers the notch of the water guide groove. With the above technical solution, the operation mask covering the notch can reduce the possibility of other foreign objects entering the water guide groove from the outside, and at the same time can also reduce the possibility of the liquid outlet hole being blocked, so that the water guide groove can smoothly guide the liquid through the liquid outlet hole, and can also effectively maintain the cleanliness of the operation interface and keep the beauty of the operation interface.

[0017] Preferably, the base is provided with a liquid leakage hole, which is located below the liquid outlet hole, and the inside of the base is communicated with the outside through the liquid leakage hole. With the foregoing technical solution, after the liquid drips from the liquid outlet hole, it can flow to the outside of the base through the liquid leakage hole, thereby reducing the accumulation of liquid inside the base, reducing the impact of the liquid on the internal components of the base, and helping to extend the service life of the electromagnetic cooking device; in addition, since the liquid leakage hole is located below the liquid outlet hole, the liquid can flow out of the base through the liquid leakage hole more quickly, effectively reducing the liquid flowing inside the base.

[0029] As Figures 1 to 4 shown, this embodiment shows an electromagnetic cooking device, including a base 3, an upper cover 1, and a panel assembly 4. The upper cover 1 is installed on the base 3. The panel assembly 4 includes a first panel 41 and a concave panel 42. The first panel 41 is provided with a mounting hole. The rim of the concave panel 42 is mounted on the first panel 41. The middle part of the concave panel 42 passes through the mounting hole and extends into the base 3. An electromagnetic coil disk 31, a main control board 32, and a cooling fan 33 are provided in the base 3. The overall structure of the electromagnetic coil disk 31 matches that of the concave panel 42, that is, the electromagnetic coil disk 31 is of a concave structure. There is a heat insulation gap between the electromagnetic coil disk 31 and the concave panel 42. After the electromagnetic coil disk 31 is powered on, a heating area is formed on the upper side of the concave panel 42. In addition, the cooling fan 33 is installed on one side of the main control board 32, and a wind shield is installed on the upper side of the cooling fan 33. After the cooling fan 33 is started, the wind shield can converge the airflow formed by the cooling fan 33 and guide the airflow to the main control board 32, thereby improving the heat dissipation effect of the main control board 32. Of course, it can be understood that in other embodiments, the panel assembly 4 may also include a first panel 41 and a second panel that are both flat structures.

[0030] As shown Figures 1 to 3 in the figure, in this embodiment, the upper cover 1 has an operation interface 11 which is inclined. A display board 34 is provided in the base 3, and the display board 34 is fixed to the bottom of the operation interface 11. A plurality of buttons 341 are provided on the display board 34. The user can control the operation and function switching of the electromagnetic cooking device through the buttons 341. A through hole 111 for avoiding the buttons 341 is provided on the operation interface 11. The upper cover 1 further has an operation mask 12. An adhesive is provided on the side of the operation mask 12 facing the operation interface 11, and the operation mask 12 is adhered to the surface of the operation interface 11 through the adhesive. In addition, a water guide groove 2 is provided on the operation interface 11. In the inclined direction of the operation interface 11, at least a part of the water guide groove 2 is located above the buttons 341 to block the liquid from flowing along the operation interface 11 into the buttons 341. A liquid outlet hole 21 is provided in the water guide groove 2, and the water guide groove 2 guides the liquid to leave the operation interface 11 through the liquid outlet hole 21.

[0031] In this embodiment, a water guide groove 2 is provided on the operation interface 11. A part of the water guide groove 2 is located above the buttons 341. When liquids such as oil or sewage slide down along the operation interface 11, the liquid above the buttons 341 will enter the water guide groove 2. The water guide groove 2 can block liquids such as oil or sewage, and can effectively limit the direct sliding of liquids such as oil or sewage along the operation interface 11 onto the buttons 341, reducing the possibility of the buttons 341 malfunctioning due to the influence of liquids such as oil or sewage. The water guide groove 2 can effectively protect the buttons 341, so that the buttons 341 can maintain a high sensitivity. In addition, a liquid outlet hole 21 is provided in the water guide groove 2. When liquids such as oil or sewage enter the water guide groove 2, the water guide groove 2 can guide the liquid to leave the operation interface 11 through the liquid outlet hole 21, thereby reducing the accumulation of liquid in the water guide groove 2 and avoiding the overflow of the water guide groove 2 due to excessive liquid accumulation, improving the protection ability of the water guide groove 2 for the buttons 341. At the same time, the water guide groove 2 can continuously guide the liquid to leave the operation interface 11, thereby effectively prolonging the service life of the water guide groove 2 and enabling the buttons 341 to maintain a high sensitivity.

[0032] As Figure 2 and Figure 3As shown, in this embodiment, there are multiple buttons 341 on the operation interface 11, and the buttons 341 are spaced apart along the length direction of the operation interface 11. In the inclined direction of the operation interface 11, the water guide groove 2 is at least partially distributed along the length direction of the operation interface 11 above the buttons 341. When the liquid above the buttons 341 enters between the operation interface 11 and the operation mask 12 and slides down along the operation interface 11, the liquid will enter the water guide groove 2, thereby restricting the liquid from directly sliding down along the operation interface 11 onto the buttons 341. In addition, the water guide groove 2 above the buttons 341 extends downward to the lower side of the buttons 341, and the lower end of the water guide groove 2 extends to the lower side of the buttons 341. The liquid outlet hole 21 is at the lower end of the water guide groove 2. After the liquid flows along the operation interface 11 into the water guide groove 2 above the buttons 341, under the action of its own gravity and the guidance of the water guide groove 2, the liquid flows to the lower end of the water guide groove 2 and finally flows out through the liquid outlet hole 21, thereby reducing the liquid in the water guide groove 2, avoiding the accumulation of liquid in the water guide groove 2, enabling the water guide groove 2 to continuously and permanently guide the liquid away from the operation interface 11, providing long-term and effective protection for the buttons 341, and effectively extending the service life of the buttons 341. Secondly, the water guide groove 2 extends to the lower side of the buttons 341, which can increase the volume of the water guide groove 2, enabling the water guide groove 2 to hold more liquid and reducing the possibility of liquid overflowing from the water guide groove 2. In addition, after the liquid enters the water guide groove 2, it will flow along the water guide groove 2 to the lower side of the buttons 341. Even if the liquid overflows from the water guide groove 2, the overflowed liquid is still on the lower side of the buttons 341, reducing the possibility of the liquid flowing to the buttons 341, which helps to improve the protection effect of the water guide groove 2 on the buttons 341.

[0033] In order to prevent liquid from spreading to the button 341 from both sides of the button 341, in this embodiment, both sides of the button 341 are provided with water guide grooves 2, and the water guide grooves 2 on both sides of the button 341 are in communication with the water guide groove 2 on the upper side of the button 341. After the liquid flows along the operation interface 11 into the water guide groove 2 on the upper side of the button 341, the water guide groove 2 guides the liquid to flow out from both sides of the button 341 to the liquid outlet hole 21. Thus, it can effectively prevent the liquid from spreading from the side of the button 341 to the liquid area during the process of the liquid sliding down along the operation interface 11, and improve the protection effect of the water guide groove 2 on the liquid. In addition, when all the buttons 341 on the operation interface 11 are spaced apart along the operation interface 11, a water guide groove 2 is provided on the left side of the leftmost button 341, a water guide groove 2 is provided on the right side of the rightmost button 341, and a water guide groove 2 is provided between two adjacent buttons 341. In this way, both sides of each button 341 can be provided with water guide grooves 2. In this way, while ensuring that the water guide groove 2 plays a protective role for the button 341, the number of water guide grooves 2 on the operation interface 11 can be reduced. Furthermore, it can maintain a sufficient contact area between the operation interface 11 and the operation mask 12, making the bonding between the operation mask 12 and the operation interface 11 more firm and reliable. In addition, by providing a water guide groove 2 between two adjacent buttons 341, it can prevent the liquid from being between the two buttons 341 and causing mutual influence between the two buttons 341, reducing the possibility of the button 341 being insensitive or malfunctioning.

[0034] Of course, it can be understood that in other embodiments, the water guide groove 2 can also directly surround all the buttons 341, and the liquid outlet hole 21 is provided in the water guide groove 2 on the lower side of the button 341. After the water guide groove 2 surrounds the button 341, all the liquid flowing to the button 341 will enter the water guide groove 2, and the water guide groove 2 can effectively limit the direct inflow of liquids such as oil or sewage onto the button 341 or between two adjacent buttons 341.

[0035] Of course, it can be understood that in other embodiments, when there are some buttons 341 independently distributed in the operation interface 11, or when the distance between the buttons 341 is relatively large, a separate water guide groove 2 can be provided at the position of the independently distributed button 341, that is, multiple non - communicating water guide grooves 2 can be provided on the operation interface 11 according to the distribution of the buttons 341.

[0036] As Figure 3 and Figure 4 shown, in this embodiment, the notch of the water guide groove 2 is formed on the operation interface 11. After the operation mask 12 is bonded and fixed to the operation interface 11, the operation mask 12 covers the notch of the water guide groove 2. Thus, it can reduce the possibility of other foreign objects entering the water guide groove 2 from the outside, and at the same time, it can also reduce the possibility of the liquid outlet hole 21 being blocked, so that the water guide groove 2 can smoothly guide the liquid through the liquid outlet hole 21, and at the same time, it can effectively maintain the cleanliness of the operation interface 11 and keep the beauty of the operation interface 11.

[0037] As Figure 4 shown, in this embodiment, the water guide grooves 2 on both sides of the button 341 include a first groove section 23 and a second groove section 24 that communicate with each other. In the inclined direction of the operation interface 11, the first groove section 23 is on the upper side of the second groove section 24. The depth of the first groove section 23 is less than that of the second groove section 24. The water guide groove 2 includes a bottom wall 22 and a lower side wall at the lower end of the water guide groove 2. The bottom end of the lower side wall is connected to the lower end of the bottom wall 22, and the top end of the lower side wall extends to the operation interface 11. The lower side wall is at the end of the second groove section 24 away from the first groove section 23, and the liquid outlet hole 21 is provided on the lower side wall. By increasing the depth of the second groove section 24, the height of the lower side wall can be increased, that is, the area of the liquid outlet hole 21 can be increased, so that the liquid can flow out of the water guide groove 2 through the liquid outlet hole 21 faster, reducing the accumulation amount of the liquid in the water guide groove 2; in addition, increasing the liquid outlet hole 21 can also reduce the possibility of the liquid outlet hole 21 being blocked, enabling the liquid to flow smoothly through the liquid outlet hole 21; secondly, increasing the depth of the second groove section 24 can also increase the volume of the water guide groove 2, enabling the water guide groove 2 to hold more liquid and reducing the possibility of the liquid overflowing from the water guide groove 2.

[0038] As Figure 4 shown, in the inclined direction of the operation interface 11 in this embodiment, the projection position of the liquid outlet hole 21 on the operation mask 12 is on the lower side of the projection position of the display board 34 on the operation mask 12. When the liquid drips through the liquid outlet hole 21, the dripping position of the liquid is also on the lower side of the display board 34. Thus, it can be avoided that the liquid directly drips onto the display board 34 after passing through the liquid outlet hole 21, reducing the influence of liquids such as oil or sewage on the display board 34 and providing effective protection for the normal operation of the display board 34; in addition, by setting the liquid outlet hole 21 on the lower side wall, the liquid flows along the bottom wall 22 to the lower side wall and finally detaches from the water guide groove 2 through the liquid outlet hole 21. During the dripping process of the liquid, the bottom wall 22 can play a shielding role for the display board 34, effectively avoiding the liquid directly dripping onto the display board 34, and at the same time, the distance between the liquid outlet hole 21 and the display board 34 can be increased, further reducing the possibility of the liquid dripping onto the display board 34.

[0039] Of course, it can be understood that in other embodiments, the liquid outlet hole 21 can also be provided on the bottom wall 22 of the water guide groove 2, and the water outlet hole is at the connection between the bottom wall 22 and the lower side wall. After the liquid enters the water guide groove 2, it will flow along the bottom wall 22 to the lower end of the water guide groove 2. By setting the liquid outlet hole 21 on the bottom wall 22 at the lower end of the water guide groove 2, it can be ensured that the liquid can flow out of the water guide groove 2 through the liquid outlet hole 21, reducing the accumulation amount of the liquid in the water guide groove 2.

[0040] As Figure 3 and Figure 4As shown, in order to reduce the accumulated amount of liquid in the base 3, in this embodiment, the base 3 is provided with liquid leakage holes, which are located below the liquid outlet holes 21. The inside of the base 3 communicates with the outside through the liquid leakage holes. After the liquid drips from the liquid outlet holes 21, it can flow to the outside of the base 3 through the liquid leakage holes, thereby reducing the accumulated amount of liquid inside the base 3, reducing the impact of the liquid on the internal components of the base 3, and helping to extend the service life of the electromagnetic cooking device; in addition, the liquid leakage holes are located below the liquid outlet holes 21, which can accelerate the outflow of the liquid from the base 3 through the liquid leakage holes, and can effectively reduce the liquid flowing inside the base 3.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
