Description

Technical Field

[0001] The utility model belongs to the technical field of integrated kitchen appliances, in particular to an integrated oven switch and an oven. Background Art

[0002] In traditional oven designs, ovens are all adjusted to bake through a combination of gears, temperature control, and timing. For example, Chinese Utility Model No. 2015211091837 discloses an integrated oven switch with gears and temperature control, which includes a gear switch, a connecting clamp, and a temperature control switch. The connecting clamp is connected between the gear switch and the temperature control switch, with one end of the connecting clamp clamping the gear switch tightly fitted; the other end of the connecting clamp is aligned with the end surface of the temperature control switch with an interference fit; the temperature control rotating rod is in contact with the gear switch axis; when the gear switch shaft rotates, the temperature control switch shaft rotates synchronously.

[0003] However, with the improvement of people's living standards, traditional ovens need to be equipped with some other functions in addition to baking, such as ventilation, cleaning, defrosting, etc., and the above functions often do not require temperature adjustment. Therefore, the switch in the above patent is not applicable to the above situation. It will cause the temperature control switch to perform some meaningless rotation, thereby causing it to be damaged and affecting the stable switch life. Summary of the Invention

[0034] The present invention will be further described below in conjunction with specific embodiments:

[0035] An integrated oven switch includes a gear switch 1 and a temperature control switch 2. The gear switch 1 has a baking gear 14 and at least one functional gear. When the gear switch 1 is in the baking gear 14, the oven performs a baking action. The temperature control switch 2 is used to adjust the temperature of the oven during the baking action. The connecting component 3 is arranged between the gear switch 1 and the temperature control switch 2. When the gear switch 1 is in the baking gear 14, the connecting component 3 is activated and connects the gear switch 1 and the temperature control switch 2 for synchronous movement.

[0036] like Figure 1As shown, the gear switch 1 includes a base 11, which is square in shape as a whole. A hollow portion is provided in the middle of the base 11, and a rotating spindle 13 is provided on the hollow portion. The rotating spindle 13 is passed through one end of the base 11, and a handle is provided on the rotating spindle 13 outside the base 11, which is used to drive the rotating spindle 13 to rotate through the handle. Terminals 12 are provided on both sides of the rotating spindle 13, and the terminal 12 is used to connect to the wires in the circuit. A paddle is vertically connected below the terminal 12, and the paddle extends to the hollow portion and is located below the rotating spindle 13. A number of paddle blocks 131 corresponding to the paddles are provided on the rotating spindle 13. The position of the paddle blocks 131 can be designed so that when the rotating spindle 13 is rotated, the corresponding paddles on the base 11 are connected to connect different circuits in the circuit to achieve adjustment of the oven gear.

[0037] In this embodiment, the gear switch 1 has two functional gears: a stop gear 15 and a defrost gear 16. In these two gears, the oven does not heat. Conventional ovens are equipped with electric heating tubes, fans, and lights. In the stop gear 15, the electric heating tubes, fans, and lights in the oven do not operate. In the defrost gear 16, the fans and lights operate, but the electric heating tubes do not. In the baking gear 14, the electric heating tubes, fans, and lights in the oven all operate. When the user rotates the rotating spindle 13, the stop gear 15, defrost gear 16, and baking gear 14 are sequentially switched. When in the baking gear 14, the coupling assembly 3 operates to connect the gear switch 1 and the temperature control switch 2 for synchronous movement. Further rotation of the gear switch 1 then synchronously drives the temperature control switch 2 to adjust the temperature in the baking gear 14.

[0038] Specifically, the coupling assembly 3 includes a joint 32, which is rotatably arranged in the gear switch 1 and coaxially opposite to the rotating main shaft 13. A boss portion 4 for engaging with each other is provided on one end of the rotating main shaft 13 and one end of the joint 32, and a disengagement inclined surface 41 is provided on the boss portion 4; the other end of the joint 32 is provided with a reset member that gives the joint 32 a tendency to move toward the rotating main shaft 13, and is used for driving the joint 32 to engage with the rotating main shaft 13 when the rotating main shaft 13 and the boss portion 4 on the joint 32 are staggered; the temperature control switch 2 is provided with a rotation adjustment rod 21 connected to the joint 32, and the rotation adjustment rod 21 has a maximum rotation position that limits its rotation. When the rotation adjustment rod 21 is at its maximum rotation position, the rotating main shaft 13 rotates and separates from the joint 32 through the disengagement inclined surface 41.

[0039] like Figure 1 、 2As shown in , 4, a mounting hole 111 is provided on the machine base 11, and the mounting hole 111 is arranged opposite to the rotating main shaft 13. The joint 32 is cylindrical and is rotatably arranged in the mounting hole 111. The rotating adjustment rod 21 is irregularly shaped, and an irregular groove 31 connected to the rotating adjustment rod 21 is formed in the joint 32. The linkage between the joint 32 and the rotating adjustment rod 21 is achieved by inserting the rotating adjustment rod 21 into the irregular groove 31.

[0040] The boss portion 4 is arranged on the opposite end of the joint 32 and the rotating main shaft 13. In this embodiment, the boss portion 4 is arranged around the end of the joint 32 and the rotating main shaft 13, and a groove is formed between the boss portion 4. The joint 32 can be engaged with the rotating main shaft 13 through the groove. One side edge of each of the boss portions 4 is inclined to obtain the disengagement slope 41. When the cam 32 is in engagement with the cam 32, the cam 32 is engaged with the cam 32 and the cam 32 is engaged with the cam 32.

[0041] Based on this characteristic, the maximum rotation position of the rotation adjustment lever 21 and the maximum rotation position of the rotation main shaft 13 are adjusted to enable the separation of the rotation main shaft 13 and the joint 32 to correspond to the switching between the grilling gear 14 and other functional gears. In this embodiment, for ease of explanation, this embodiment is described in terms of angles as a specific unit of measurement. That is, the maximum rotation angle of the rotation adjustment lever 21 is limited to 180 degrees, while the maximum rotation angle of the rotation main shaft 13 is limited to 270 degrees. At the same time, the maximum rotation position of the rotation adjustment lever 21 is consistent with the maximum rotation position of the rotation main shaft 13. That is, the rotation main shaft 13 can drive the rotation adjustment lever 21 to rotate synchronously by a maximum of 180 degrees. The excess 90 degrees is stopped due to the separation of the joint 32 and the rotation main shaft 13.

[0042] At this time, if Figure 5 、 6As shown, the user can adjust the 90-degree angle to correspond to the stop position 15 and the defrost position 16 of the gear switch 1. Within this range, the joint 32 and the rotating main shaft 13 no longer engage, and the boss portion 4 thereon is in a mutually abutting state. The rotating main shaft 13 switches between the stop position 15 and the defrost position 16 every 45 degrees of rotation. After the rotating main shaft 13 rotates more than 90 degrees, the rotating main shaft 13 and the boss portion 4 on the joint 32 are offset. The joint 32 re-engages with the rotating main shaft 13 under the action of the reset member, and the grilling gear 14 is now entered. Rotating the gear switch 1 can also drive the rotating adjustment lever 21 on the temperature control switch 2 to adjust the temperature, thereby achieving synchronous movement of the gear switch 1 and the temperature control switch 2, that is, the temperature control switch 2 can be controlled by the gear switch 1 alone. When the user needs to switch back to the functional gear, the user rotates the gear switch 1 in the opposite direction. Since the maximum rotation angle of the rotation adjustment rod 21 is different from the maximum rotation angle of the rotation main shaft 13, the rotation main shaft 13 drives the rotation adjustment rod 21 to rotate 180 degrees through the joint 32. The rotation adjustment rod 21 is restricted, while the rotation main shaft 13 can continue to rotate. At this time, the boss portion 4 between the joint 32 and the rotation main shaft 13 separates the two, so that the rotation adjustment rod 21 is no longer controlled by the rotation main shaft 13. In summary, this patent links the gear switch 1 and the temperature control switch 2 through the connecting assembly 3 to reduce the frequency of rotation of the temperature control switch 2 and reduce the rotatable angle of the temperature control switch 2, thereby reducing the loss of the temperature control switch 2 during use and increasing the service life of the temperature control switch 2.

[0043] Furthermore, the reset member includes a pressing piece 5 fixed on the machine base 11, and the pressing piece 5 is provided with an elastic strip portion 51 pressed against the end of the joint 32. Figure 3 As shown, the upper and lower ends of the pressing plate 5 are provided with claw portions 53 for fixing it to the machine base 11. The upper and lower engagement of the claw portions 53 realizes the fixation of the pressing plate 5. The middle part of the pressing plate 5 is provided with a through hole for the rotation adjustment rod 21 to pass through, and an elastic bar portion 51 is provided outside the through hole opposite to the joint 32. The elastic bar portion 51 presses the joint 32 inward to achieve reset. The pressing plate 5 is also provided with a connecting frame 52, which is connected to the temperature control switch 2 through the connecting frame 52. The connecting frame 52 is located on both sides of the active part of the pressing plate 5. The only raised cross bar is inserted into the through hole of the temperature control switch 2 to achieve positioning and fixation, thereby facilitating the installation of the temperature control switch 2.

[0044] In addition, since the present invention reserves a 180-degree interval for the baking gear 14 for the temperature control switch 2 to adjust the temperature, sufficient space is reserved to increase the stability of the temperature control switch 2 and increase the adjustment accuracy. In other embodiments, a maximum of 270 degrees interval can be reserved for the baking gear 14 service.
