It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

The invention provides a toaster, which comprises a shell 100, wherein a function sliding key 1 and a time sliding key 2 which are pressed vertically and can be reset after being pressed are arranged on the shell 100, as shown in figures 3 to 6. Wherein, function sliding key 1 can slide along vertical direction to select or switch function gear position, and time sliding key 2 can slide along vertical direction to select or switch time gear position.

Compared with the existing toaster (shown in figures 1 and 2) which adopts the rotary button 17 to adjust the time gear and adopts the press key 18 to adjust the function gear, the toaster of the invention can not generate the situation of slip failure due to long-term sliding friction of the function sliding key 1 or the time sliding key 2, thereby improving the reliability and the durability of the toaster. In addition, the function sliding key 1 sliding vertically and progressively is beneficial to adding more gears in the control panel 200 of the toaster so as to enable the functions of the toaster to be more diversified, and under the optimal condition, the function sliding key 1 and the time sliding key 2 can be arranged on the same side wall of the shell 100 in parallel, so that the whole sliding key structure is more compact and reasonable. Moreover, the function sliding key 1 or the time sliding key 2 of the toaster can be automatically reset after being selected or switched to a target gear, namely, a user does not need to manually adjust the sliding key to reset after using the toaster, so that the use of the toaster is greatly facilitated, and the user has excellent use experience.

Specifically, the toaster of the present invention is further provided with a function electric control board 41 corresponding to the function slide key 1 and a time electric control board 42 corresponding to the time slide key 2, wherein the function electric control board 41 and the time electric control board 42 are preferably arranged in parallel and spaced apart. Further, one of the upper or lower ends of the electric control board may be snap-coupled to the side wall of the housing 100, and the other may be fastened by the fastening member 6. Therefore, during assembly operation, only a single screw is needed for fixing, the assembly efficiency is greatly improved, and the assembly cost is reduced.

In order to ensure that the sliding key can adjust the working time and the working state of the toaster, in the present embodiment, an adjustable resistor 3 which is fixed vertically may be preferably arranged on the electric control board. At this time, the function slide key 1 and the time slide key 2 are respectively connected with a contact slider 31 to slidably contact the respective adjustable resistors 3, and the slide keys can be vertically slid to adjust the resistance values of the respective adjustable resistors 3. In addition, the toaster further comprises a guide rod arranged in parallel with the adjustable resistor 3 and a reset elastic piece sleeved on the guide rod, wherein the reset elastic piece can drive the sliding key to reset after being pressed.

During the sliding process of the sliding key to the target gear, the resistance value of the connected adjustable resistor 3 can be synchronously changed. Meanwhile, the control circuit of the toaster can quickly generate an execution electric signal for adjusting the working time or switching the working state after receiving the changed resistance value signal, thereby achieving the operation purpose of a user. It should be noted that, in the sliding process of the sliding key, the elastic resetting piece sleeved on the guide rod is in a state of continuous stretching or continuous compression, and when the toaster finishes time adjustment or function switching, the elastic resetting piece can rapidly drive the sliding key to reset, thereby saving the manual resetting operation of a user.

Besides the adjustable resistor 3, other structures and manners can be adopted to realize gear adjustment, such as a proximity switch, a relay trigger and the like. Moreover, the manner of realizing automatic reset of the sliding key is not limited to the arrangement of the reset elastic element, and for example, program control of a chip and the like can be performed, which is not described in detail herein.

Further, the above-mentioned guide bars may include a function key guide bar 51 and a time key guide bar 52. The function sliding key 1 is slidingly fitted on the function key guide rod 51, and the time sliding key 2 is slidingly fitted on the time key guide rod 52. At this time, the function key guide rod 51 and the time key guide rod 52 may be individually or simultaneously sleeved with a reset elastic member, thereby implementing automatic reset of the function slide key 1 or the time slide key 2.

In the present embodiment, the return elastic member may be preferably provided as a spring. When the bottom end of the return elastic element is fixed and the top end is pressed against the bottom end of the sliding key, the return elastic element is formed to compress the return spring 11. Alternatively, when the top end of the return elastic member is fixed and the bottom end is connected to the slide key, it is formed to stretch the return spring. It can be seen that no matter the compression return spring 11 or the extension return spring is used, the slide key can have the automatic return function as long as the relative position between the return elastic piece and the slide key is set reasonably.

In addition, the side wall of the housing 100 may be provided with a vertical rib 7 protruding perpendicular to the side wall surface, and the vertical rib 7 is provided with a vertical through-slot 71 through which the contact sliding piece 31 passes. At the moment, the electric control plate and the adjustable resistor 3 thereof can be arranged on the side wall of the vertical rib plate 7, so that the assembly structure is more compact and the layout is more reasonable.
