DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The single knob control device provided by the embodiment of the present invention is as follows: Figure 2 As shown, it includes: electronic control mainboard 3, control panel 4, knob 2 and parameter selection key. The specific structure of the above components can be referred to Figure 4 As shown;

[0036] The electronic control main board 3 is installed on the control panel 4 and is provided with an encoder 31 or a potentiometer; the knob 2 is installed on the control panel 4 and is rotationally connected to the encoder 31 or the potentiometer of the electronic control main board 3; the parameter selection key is installed on the control panel 4 and is electrically connected to the electronic control main board 3.

[0037] In this solution, it should be noted that the parameter selection key can select at least two parameters, such as heating temperature and heating time. In addition, the free rotation of the knob 2 drives the rotation of the encoder 31 or potentiometer of the electronic control board 3, which, in conjunction with the use of the parameter selection key, can further adjust the operating mode, temperature, time, or start / stop functions. To better understand the control process of this solution, its working principle is now introduced as follows:

[0038] First, rotate the knob 2 to drive the encoder 31 or potentiometer of the electronic control mainboard 3 to rotate, so as to select the corresponding working mode (such as selecting the toasting mode or the barbecue mode). After selecting the corresponding working mode, press the parameter selection key to select the parameter to be adjusted (such as selecting the heating temperature or the heating time). Then, rotate the knob 2 again to drive the encoder 31 or potentiometer of the electronic control mainboard 3 to rotate, so as to adjust the selected parameter (such as adjusting the high or low temperature of the heating or increasing or decreasing the heating time). Finally, start it. In other words, the control process of the present device is: rotate the knob 2 to select the working mode - press the parameter selection key to select the parameter to be adjusted - rotate the knob 2 again to adjust the size of the parameter; in this way, the integrated control and adjustment of the working mode, temperature, time or start and stop functions is realized, which is not only more convenient to operate, but also saves the user's operation time.

[0039] It can be seen from the above technical solution that in the single-knob control device provided in the embodiment of the present invention, the working mode is first selected by rotating the knob, and then the parameter to be adjusted is selected by pressing the parameter selection key, and then the size of the parameter is adjusted by rotating the knob, thereby realizing the integrated control adjustment of the working mode, temperature, time or start and stop functions. That is to say, this solution integrates multiple control functions into a set of single-knob control devices. In this way, the solution has the characteristics of convenient control, time and labor saving, high control integration and small control space occupation; at the same time, it also helps to greatly improve the user experience; based on this, the solution is particularly suitable for electric ovens, air fryers or air fryer ovens.

[0040] Specifically, if Figure 2 As shown, the electronic control mainboard 3 is distributed on the first side of the control panel 4 (as shown in FIG. Figure 2 The knob 2 is distributed on the second side of the control panel 4 (such as Figure 2 The front side of the central control panel 4) and penetrates the control panel 4 and is rotatably connected to the encoder 31 or potentiometer of the electronic control mainboard 3; the parameter selection key is provided on the knob 2. This design has the characteristics of clear structural hierarchy, compact structure and easy assembly, thus facilitating the modular design of the device.

[0041] In this program, if Figure 4 As shown, the electronic control mainboard 3 is provided with a plurality of mode indicator lights 32, which are distributed in a semicircle around the encoder 31 or the potentiometer; of course, different mode indicator lights 32 represent different working modes;

[0047] like Figure 2 As shown, the display assembly 1 is installed in the knob groove 21, passes through the knob 2, and is fixedly connected to the electronic control motherboard 3. In other words, the display assembly 1 is built into the knob 2 and fixedly connected to the electronic control motherboard 3, allowing the knob 2 to rotate relative to the display assembly 1. This design offers the advantages of a compact structure, minimal space occupation, high integration, and convenient operation.

[0048] Specifically, if Figure 4 As shown, the knob groove 21 of the knob 2 is provided with a knob through hole;

[0049] like Figure 4 As shown, the display assembly 1 includes: a display panel fixing seat 11, a display panel 12 and a display cover 13;

The display panel mounting base 11 is mounted within the knob groove 21, and its fixing post extends through the knob through-hole to securely connect to the electronic control motherboard 3. The display panel 12 is mounted within the mounting groove 111 and electrically connected to the electronic control motherboard 3. The display cover 13 is mounted to the top of the mounting groove 111. This design of the display assembly 1 in this embodiment results in a compact structure and minimal space consumption.

[0051] Furthermore, if Figure 4 As shown, the parameter selection keys include: a time touch spring key 72, a temperature touch spring key 71 and / or a start / stop touch spring key 73; thus, the present solution is designed so as to facilitate the control of functions such as time, temperature or start / stop;

[0052] The time touch spring button 72, the temperature touch spring button 71 and / or the start / stop touch spring button 73 are installed between the display panel 12 and the display cover 13. This solution is designed in this way, and the hidden touch design of the parameter selection key can be realized, which has the characteristics of compact structure and convenient operation.
