Description

Technical Field

[0001] The utility model relates to the technical field of trigger components, in particular to a contact switch assembly. Background Art

[0002] A steak machine and an air fryer cannot be used interchangeably due to their different main body structures and working modes. Generally, a steak machine has upper and lower grilling seats hinged together and cooks steaks by frying, while an air fryer includes at least a device main body and a pot body assembly and cooks various foods by frying and roasting. When considering designing the grilling pan of the steak machine and the pot body assembly of the air fryer as detachable structures, or there is a possibility of integrating the two into an integrated device to achieve the purpose of dual use of one machine.

[0003] In these two different working modes, the longitudinal position of the upper grilling seat is different and corresponding detection is required. The state of the upper grilling seat covering the pot body assembly also needs to be detected so that the controller in the cooking device can determine and adjust to the corresponding working mode based on the detection results. Otherwise, there will be problems such as mis-starting or mismatched working modes. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, a contact switch assembly is provided herein, aiming to ensure the use safety and reliability of the whole machine, avoid mis-starting or mismatched working modes, and overcome at least one of the above technical defects.

[0005] The specific technical solution is as follows:

[0008] Preferably, the lower end surface of the pot body assembly has a first ejector rod opposite to the detection end of the first microswitch. The first ejector rod serves as a first trigger member, and when the pot body assembly is disposed on the lower grilling seat, the first ejector rod touches the detection end of the first microswitch, causing the control module of the steak machine to determine that the pot body assembly is in place for installation.

[0009] Preferably, the detection part of the second micro switch is configured as a connecting rod structure whose middle part is hinged to the trigger end of the second micro switch, and the two ends of the connecting rod structure respectively extend downward to form a first bump and a second bump, so as to cause the second micro switch to be triggered only when the first bump and the second bump are stressed simultaneously.

[0010] Preferably, the upper end of the pot body assembly has a second ejector rod opposite to the position of the first bump. When the second ejector rod touches the first bump and the second bump touches the upper end of the pot body assembly, the control module of the steak machine determines that the upper grilling seat has been covered on the pot body assembly.

[0011] Preferably, the length of the first bump in the longitudinal direction is less than the length of the second bump in the longitudinal direction.

[0012] Preferably, at least part of the end of the first bump extends downward from the lower end surface of the upper grilling seat.

[0013] The beneficial effects of the above technical solutions are as follows:

[0014] The contact switch assembly is applied to a multi-functional steak machine and includes a first micro switch and a second micro switch, which are respectively used to detect whether the pot body assembly is installed in place and whether the upper grilling seat is covered on the pot body assembly. It can be detected when the steak machine is converted into an air fryer to use, so as to ensure that the assembly is in place and prompt the working mode of the whole machine to be changed from a steak machine to an air fryer, effectively ensuring the use safety and reliability of the whole machine and avoiding problems such as mis-starting or mismatching of the working mode.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following embodiments will specifically describe the present utility model in conjunction with the accompanying drawings. And it is defined that the direction inward perpendicular to the paper surface as shown in Figure 6 is the direction from the back to the front in this embodiment.

[0022] Referring to Figures 1 to 6 as shown, the contact switch assembly provided in this embodiment is applied to a multi-functional steak machine. The multi-functional steak machine includes a lower grilling base 1 and an upper grilling base 2 pivotally connected, and a pot body assembly 3 detachably disposed between the two grilling bases. The longitudinal position of the upper grilling base 2 is adjustable and has a first position for using the whole machine as a steak machine and a second position for using it as an air fryer. Among them, the contact switch assembly includes a first microswitch 7 disposed inside the lower grilling base 1 and a second microswitch 8 disposed inside the upper grilling base 2. The first microswitch 7 is used to detect whether the pot body assembly 3 is installed in place, and the second microswitch 8 is used to detect whether the upper grilling base 2 is covered on the pot body assembly 3.

[0023] Based on the above technical solution, the contact switch assembly is applied to a multi-functional steak machine and includes a first microswitch 7 and a second microswitch 8, which are respectively used to detect whether the pot body assembly 3 is installed in place and whether the upper grilling base 2 is covered on the pot body assembly 3. It can detect when the steak machine is converted to be used as an air fryer to ensure that the assembly is in place and prompt the working mode of the whole machine to be changed from a steak machine to an air fryer, effectively ensuring the use safety and reliability of the whole machine and avoiding problems such as mis-starting or mismatched working modes.

[0024] In a preferred embodiment, the lower end surface of the pot body assembly 3 has a first ejector rod 33 opposite to the detection end 71 of the first microswitch 7. The first ejector rod 33 serves as a first triggering member. When the pot body assembly 3 is disposed on the lower grilling base 1, the first ejector rod 33 touches the detection end 71 of the first microswitch 7, and the control module of the steak machine determines that the pot body assembly 3 has been installed in place. Thus, it switches from the steak machine mode to the air fryer mode. On the contrary, when the pot body assembly 3 is removed, the first microswitch 7 is in an undetected state and it is determined that the pot body assembly 3 is not installed, and it remains in the steak machine mode.

[0025] In a preferred embodiment, the detection portion 81 of the second microswitch 8 is configured as a link structure hinged in the middle to the trigger end of the second microswitch 8, and the two ends of the link structure respectively extend downward to form a first bump 82 and a second bump 83, so as to cause the second microswitch 8 to be triggered only when the first bump 82 and the second bump 83 are both stressed. Further, the upper end of the pot body assembly 3 has a second ejector rod 34 opposite to the position of the first bump 82. When the second ejector rod 34 touches the first bump 82 and the second bump 83 touches the upper end of the pot body assembly 3, the control module of the steak machine determines that the upper grilling seat 2 has been covered on the pot body assembly 3, so that the heating assembly 6 is in a startable state. On the contrary, if neither of them is in contact or only one of them is in contact, it is determined that the cover is not fully closed or in the working mode of the steak machine. Combined with the above-mentioned first microswitch 7, the assembly of the pot body assembly 3 is jointly determined, so the safety is higher and the mis-start state will not occur. Further, the length of the first bump 82 in the longitudinal direction is less than the length of the second bump 83 in the longitudinal direction. Further, at least part of the end of the first bump 82 extends downward from the lower end surface of the upper grilling seat 2, so that it can be retracted under force after the pot body assembly 3 is configured.

[0026] It is worth pointing out that the upper grilling seat 2 and the lower grilling seat 1 are respectively provided with detachable grilling pans to meet the grilling cavity when used as a steak machine. And the lower grilling seat 1 also has a control module, a power supply module, a control panel, and an upper and lower temperature control module (which is preferably controlled by thyristor to achieve the purpose of adjustable temperature) electrically connected to the above-mentioned various electrical components. These are all basic structures of the steak machine, so the description is omitted here. At the same time, the upper grilling seat 2 and the lower grilling seat 3 are provided with detachable grilling pans and also correspond to heating tubes, which are also basic structures. In addition, the upper grilling seat 2 and the lower grilling seat 3 are pivotally connected. Specifically, the rear side of the lower grilling seat 3 has two symmetrically arranged mounting seats 4 on the left and right. Each mounting seat is also formed with a longitudinal runway groove, and the rear side of the upper grilling seat has a rotating seat. The left and right sides of the rotating seat respectively form a rotating rod. The rotating rod extends into the runway groove and can move in the longitudinal direction, and is limited to a first position and a second position in the longitudinal direction by a locking assembly 9 disposed in the rotating seat. The pot body assembly 3 includes a mounting frame 31 detachably mounted on the lower grilling seat 1 and a pot body 32 detachably embedded in the mounting frame 31 and open upward. This is not the focus of the present application, so the description is omitted here.

[0027] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
