[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0033] Please refer to the following: Figures 1 to 8 This utility model discloses an electric stove. The electric stove can be an induction cooker or an electric ceramic cooker, and is not limited thereto. The electric stove includes a base 1, a shell 2 and a knob 3 disposed on the base 1, a display panel 4, a waterproof cover 5 fixed to the shell 2, a sensing magnet 6 disposed on the knob 3, and a sensing chip 7 disposed on the display panel 4. The side of the base 1 and / or the shell 2 is provided with a clearance opening 11 communicating with the area where the knob 3 is located. The knob 3 extends through the clearance opening 11 so that the knob can rotate under the action of external force. When the knob 3 rotates, it drives the sensing magnet 6 to rotate, so that the sensing chip 7 detects the gear signal. The display panel 4 is located between the waterproof cover 5 and the shell 2, so that the area where the display panel 4 is located is not connected to the area where the knob 3 is located. With this design, the sensor chip 7 and the sensor magnet 6 are combined to form a sensing technology. The sensor chip 7 can detect the rotation of the knob 3 to simulate the gear position. The knob 3 does not need to be directly connected to the display panel 4 for communication or power. When water from the external environment enters the area where the knob 3 is located through the avoidance port 11, the waterproof cover 5 can isolate the water vapor to prevent the water vapor on the knob 3 side from entering the display panel 4 side, thus forming an effective way to prevent water from entering the electric furnace.

[0034] Specifically, the provision of a clearance opening 11 on the side of the base 1 and / or the outer shell 2 includes: the base 1 having a clearance opening 11, the outer shell 2 having a clearance opening 11, and both the base 1 and the outer shell 2 having a clearance opening 11. In this embodiment, the clearance opening 11 is provided on the base 1 for example.

[0035] In some embodiments, to ensure that water entering the area where the knob 3 is located can be drained in a timely manner, the base 1 is also provided with a drain hole 14, which is connected to the area where the knob 3 is located, so as to drain the water in the area where the knob 3 is located to the external environment. With this design, domestic water can be efficiently drained to the outside of the whole machine.

[0036] In some embodiments, the base 1 is also provided with a waterproof rib 13, which encloses and forms an installation space. The knob 3 is located within the installation space, and the clearance opening 11 is connected to the installation space. This design effectively surrounds the knob 3 and its inner frame to prevent water entering through the clearance opening 11 from flowing to other places such as the power board.

[0037] In some embodiments, in order to install and fix the knob 3, the electric furnace also includes a bracket 8, which is fixed on the base 1. The bracket 8 is provided with a first positioning groove 81, and the knob 3 is provided with a first positioning post 32. The first positioning post 32 is inserted into the first positioning groove 81 to position the knob 3 on the bracket 8.

[0038] Furthermore, considering that the knob 3 may wobble when rotated, the waterproof cover 5 has a first support point 51 on the side facing the knob 3, which abuts against one side of the knob 3. The bracket 8 has a second support point 82 on the side facing the knob 3, which abuts against the other side of the knob 3. With this design, when the knob 3 is rotated after assembly, the first support point 51 and the second support point 82 at the top and bottom are used for balance, reducing the amount of wobble.

[0039] In addition, in order to install and fix the bracket 8 on the base 1, the base 1 is provided with a first connecting post 12 having a first connecting hole, and the bracket 8 is provided with a first connecting lug 83 having a second connecting hole. The first connecting hole and the second connecting hole are connected by fasteners.

[0040] In some embodiments, in order to install and fix the waterproof cover 5 on the outer shell 2, the outer shell 2 is provided with a second connecting post 21 having a third connecting hole, and the waterproof cover 5 is provided with a second connecting lug 52 having a fourth connecting hole. The third connecting hole and the fourth connecting hole are connected by fasteners.

[0041] In some embodiments, to secure the display panel 4, the waterproof cover 5 is provided with a second positioning post 53, and the display panel 4 is provided with a positioning hole 41. The second positioning post 53 passes through the positioning hole 41 to position the display panel 4 on the waterproof cover 5. A support post 22 is also provided on the side of the outer casing 2 facing the base 1, and the support post 22 presses the display panel 4 onto the waterproof cover 5. With this design, the cooperation of the second positioning post 53 and the positioning hole 41 can prevent the display panel 4 from moving left or right, and the support post 22 can limit the movement of the display panel 4, thereby preventing the display panel 4 from jumping up and down.

[0042] In some embodiments, the electric furnace also includes a sealing ring 9, and the waterproof cover 5 is provided with a second positioning groove 54. The sealing ring 9 is installed in the second positioning groove 54 and abuts against the outer shell 2. This design can improve the sealing between the waterproof cover 5 and the outer shell 2, thereby further improving the waterproof effect.

[0043] In some embodiments, the sensing chip 7 is bonded to the side of the display panel 4 facing the waterproof cover 5 to fix the sensing chip 7 on the display panel 4. The knob 3 is provided with a mounting groove 31 on the side facing the waterproof cover 5, and the sensing magnet 6 is installed in the mounting groove 31 to fix the sensing magnet 6 on the knob 3.

[0044] The assembly steps for the knob 3 structure in this electric furnace design are as follows:

[0045] First, the knob 3 is connected to the base 1 via the first connecting post 12 and the first connecting lug 83; further, the first positioning post 32 of the knob 3 is inserted into the first positioning groove 81 of the bracket 8 to position the knob 3 on the bracket 8.

[0046] Secondly, the display panel 4 is first assembled into the waterproof box and fixed by the second positioning post 53 and the positioning hole 41. Further, the sealing ring 9 is assembled into the second positioning groove 54. Further, the waterproof cover 5 with the pre-assembled display panel 4 is connected and fixed to the outer shell 2 by the second connecting post 21 and the second connecting lug 52. At the same time, the position of the display panel 4 is restricted by the support post 22.

[0047] Finally, assemble the assembled outer shell 2 with the assembled base 1 to complete the entire assembly.

[0048] The electric stove provided by this utility model includes a base 1, a housing 2 and a knob 3 disposed on the base 1, a display panel 4, a waterproof cover 5 fixed to the housing 2, an induction magnet 6 disposed on the knob 3, and an induction chip 7 disposed on the display panel 4. The side of the base 1 and / or the housing 2 is provided with a clearance opening 11 communicating with the area where the knob 3 is located. The knob 3 extends through the clearance opening 11 so that the knob can rotate under the action of external force. When the knob 3 rotates, it drives the induction magnet 6 to rotate so that the induction chip 7 can detect the gear signal. The display panel 4 is located between the waterproof cover 5 and the housing 2 so that the area where the display panel 4 is located is not connected to the area where the knob 3 is located. With this design, the sensor chip 7 and the sensor magnet 6 are combined to form a sensing technology. The sensor chip 7 can detect the rotation of the knob 3 to simulate the gear position. The knob 3 does not need to be directly connected to the display panel 4 for communication or power. When water from the external environment enters the area where the knob 3 is located through the avoidance port 11, the waterproof cover 5 can isolate the water vapor to prevent the water vapor on the knob 3 side from entering the display panel 4 side, thus forming an effective way to prevent water from entering the electric furnace.
