[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0030] First embodiment:
[0031] This embodiment discloses the fixing structure of the detection module.
[0032] Figure 1 This is a front view structural diagram of the kitchen appliance of this utility model. Figure 1 As shown, the detection module fixing structure is used for kitchen utensils, which include a base 1 and a tray 2 mounted on the upper end of the base 1, on which a pot 3 is placed. For example, the kitchen utensils are induction cookers, and the tray 2 is a heating plate. Of course, in other embodiments of this utility model, the detection module fixing structure can also be used for other kitchen utensils with heating functions.
[0033] Figure 2 This is a longitudinal sectional view of the kitchen appliance of this utility model. Figure 3 for Figure 2 A magnified view at point A. (See image below.) Figure 2 and Figure 3 As shown, the fixed structure of the detection module includes a cookware detector 7, a magnet 31, a first cover 4, and a second cover 5.
[0034] Magnet 31 is fixed to the lower end of cookware 3. For example, magnet 31 is embedded inside the lower end of cookware 3, ensuring that the position of magnet 31 is stable and will not detach from cookware 3 while ensuring sufficient magnetic force.
[0035] The first cover 4 is a hollow structure with its opening facing downwards, and is disposed at the lower end of the tray 2. The upper end of the first cover 4 passes through and protrudes from the upper surface of the tray 2. For example, a through hole 21 is provided at the upper end of the tray 2 for the first cover 4 to pass through.
[0036] The second cover 5 is snapped into the first cover 4. A first support 51 is provided at the lower end of the second cover 5. First clamping pieces 52 extend from both sides of the first support 51 toward the center of the second cover 5. The two first clamping pieces 52 clamp and fix the cookware detector 7 to the first support 51. The cookware 3 is placed on the tray 2, and the magnetic field of the magnet 31 triggers the cookware detector 7. For example, the side of the second cover 5 is clearance-fitted with the inner wall of the first cover 4. Several protrusions are circumferentially arranged on the inner side of the first cover 4 at the lower end of the second cover 5 to restrict the position of the second cover 5 within the first cover 4 and ensure detection effectiveness. Specifically, the protrusions are clamped out on the inner side of the first cover 4 using clamps, and the two first clamping pieces 52 are clamped to generate a clamping force on the cookware detector 7. Preferably, the first cover 4, the first support 51, and the first clamping pieces 52 are integrally bent for ease of manufacturing and production.
[0037] like Figure 3As shown, the cookware detector 7 further includes a detection element 71, a signal line 72, and a connector 73. The detection element 71 is clamped and fixed to the first bracket 51 by two first clips 52. The first end of the signal line 72 is electrically connected to the lower end of the detection element 71. The connector 73 is electrically connected to the second end of the signal line 72. In this application, electrical connection refers to the form of connection between different components in a circuit through physical lines that can transmit electrical signals, such as PCB copper foil or wires. Specifically, the detection element 71 is a Hall element. The cooperation between the Hall element and the magnet 31 is based on the Hall effect, that is, when a current passes through a conductor or semiconductor perpendicular to the magnetic field, a potential difference is generated in the direction perpendicular to the magnetic field.
[0038] like Figure 3 As shown, a flange 11 is further provided on the upper end of the base 1. A stepped portion 41 is provided on the lower end of the first cover 4. The outer diameter of the stepped portion 41 is larger than the outer diameter of the first cover 4. The detection module fixing structure also includes an elastic element 6. The first end of the elastic element 6 is sleeved on the inner side of the stepped portion 41, and the second end is sleeved on the outer side of the flange 11. The elastic element 6 always supports the first cover 4, ensuring that the first cover 4 can stably contact the lower surface of the pot 3 and guarantee the detection effect.
[0039] Figure 4 This is an isometric view of the fixed structure of the detection module of this utility model. Figure 5 This is a bottom view of the fixed structure of the detection module of this utility model. (See image below.) Figure 4 and Figure 5 As shown, further, an outer edge 42 is provided on the outer side of the stepped portion 41. Limiting posts 22 are provided on both sides of the through hole 21 at the lower end of the tray 2. The limiting posts 22 are engaged with the side of the outer edge 42, and the first cover 4 can slide up and down along the limiting posts 22. For example, a groove 421 is provided on the side of the outer edge 42 for the limiting posts 22 to engage. A washer 24 is provided at the lower end of the limiting post 22. A screw 23 passes through the washer 24 and is threaded to the lower end of the limiting post 22. The shortest distance between the edges of the two washer 24 is less than the outer diameter of the outer edge 42. The outer diameter of the stepped portion 41 is greater than the outer diameter of the through hole 21, and the tray 2 and the washer 24 restrict the vertical movement range of the first cover 4.
[0040] In this embodiment, the cookware detector 7 is fixed by clamping and fixing it to the first bracket 51 of the second cover 5, and the second cover 5 is snapped into the first cover 4, thereby fixing the cookware detector 7. The cookware 3 is placed on the tray 2, and the magnetic field of the magnet 31 triggers the cookware detector 7 to detect the cookware 3. The structure is simple and easy to install. It makes full use of the existing temperature sensor fixing structure of the kitchenware, namely the first cover 4 and the second cover 5, and has a high space utilization rate.
[0041] Second embodiment:
[0042] This embodiment discloses kitchen utensils.
[0043] like Figures 1-3 As shown, the kitchenware includes a base 1, a pot 3, and a detection module fixing structure. A tray 2 is mounted on the upper end of the base 1. The pot 3 is placed on the tray 2. As in the first embodiment, the detection module fixing structure is mounted on the base 1 and the pot 3.
[0044] like Figure 3 As shown, the kitchenware further includes a temperature sensor 8. A second bracket 53 is provided at the lower end of the first cover 4. Second clips 54 extend from both sides of the second bracket 53 toward the center of the first cover 4. The two second clips 54 clamp and fix the temperature sensor 8 to the second bracket 53.
[0045] Figure 6 This is a connection diagram of the fixing structure of the detection module of this utility model. (See diagram below.) Figure 6 As shown, the kitchen appliance further includes a controller 9, which is located inside the base 1. A connector 73 is plugged into the controller 9, and a temperature sensor 8 is electrically connected to the controller 9. The controller 9 can be a commercially available PLC controller, and the control program is existing technology.
[0046] In this embodiment, by fixing the cookware detector 7 and the temperature sensor 8 together on the second cover 5 and electrically connecting them together to the same controller 9, the increase in electrical control circuit materials and fixing structure is avoided, thus saving costs.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
