Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a door control switch and an oven. BACKGROUND

[0002] At present, many high-end ovens detect the opening and closing state of the door body through a door control switch arranged near the oven door body, and then control the on-off of the heating pipe. Specifically, when the door body is opened, the door control switch feeds back the state of the door body opening to the controller, and the controller cuts off the power supply of the heating pipe to avoid scalding and electric shock of the user.

[0003] In the prior art, the door control switch of the oven includes a shell structure installed on the oven body, and a micro switch is arranged in the shell structure. In operation, the state of the door body is detected by whether the switch contact of the micro switch is triggered by the plug pin on the oven door body pushing the sliding block to extrude the switch contact.

[0004] Although the above-mentioned scheme can accurately detect the state of the door body, the assembly tolerance of the door body is required to be high. If the assembly tolerance is large, the micro switch will be excessively extruded or even directly damaged when the door is closed, so that the door control switch is invalid, which forms a safety hazard, or the door body can be stopped by the door control switch, which causes the door to be not tightly closed. SUMMARY

[0005] The main purpose of the present application is to provide a door control switch and an oven to solve the problem that the door control switch is easily invalid in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides a door control switch for obtaining the opening and closing state of a door body, characterized in that it comprises: a mounting shell; a trigger switch installed on the mounting shell, wherein a switch contact is arranged on the trigger switch; a transmission member movably arranged on the mounting shell and having a first working position for abutting against the switch contact to trigger the trigger switch and a second working position away from the switch contact; and a biasing force member cooperating with the transmission member and having a biasing force for keeping the transmission member in the first working position; wherein when the door body is closed, the door body drives the transmission member to overcome the biasing force and move away from the switch contact to the second working position.

[0007] Further, the biasing force member is an elastic member abutting against the transmission member and the mounting shell, respectively, and the transmission member abuts against the switch contact under the elastic force of the elastic member.

[0008] Further, the elastic member has an extension stroke greater than the movement stroke of the transmission member between the first working position and the second working position.

[0009] Further, the transmission member comprises a trigger part, the door body drives the trigger part when the door body is closed to make the transmission member move against the biasing force.

[0010] Further, the transmission member is formed with a latch structure protruding from the installation shell on the trigger part.

[0011] Further, the transmission member further comprises an avoiding structure to avoid the trigger switch during the transmission member moving away from the switch contact to the second working position.

[0012] Further, the installation shell comprises a bottom shell, and the transmission member is slidably arranged in the bottom shell.

[0013] Further, the switch contact is arranged on the side of the trigger switch away from the door body.

[0014] Further, the door control switch further comprises a limiting table arranged on the installation shell to limit the transmission member in the first working position.

[0015] Further, the trigger switch is a micro switch.

[0016] Further, the door body switch is an oven door body switch.

[0017] Further, the trigger switch is electrically connected with a controller in the oven and controls the heating tube in the oven to be powered off when the door body is opened.

[0018] The present application also provides an oven comprising the door control switch.

[0019] The technical scheme of the present application has the following advantages:

[0020] 1. In the door control switch and the oven thereof, when the switch state of the door body is acquired, the transmission member is in the first working position abutting against the switch contact by the biasing force of the biasing part when the door body is opened, and the transmission member is driven by the force of the door body to move away from the switch contact to the second working position against the biasing force when the door body is closed. Compared with the prior art in which the force of the door body directly acts on the switch contact, the biasing force of the biasing part is more stable, which can ensure that the switch contact can be pressed, and the trigger switch will not be subjected to a large force when the door body is closed. The service life of the door control switch is improved, and the detection of the opening and closing state of the door body is more reliable and stable.

[0031] The technical solutions of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0033] As Figures 1 to 5 shown, according to the door control switch in the present embodiment, which is specifically an oven door control switch, is installed on the main body of the oven, and is used to obtain a switch state of the door body 80. Specifically, when the door body 80 is opened, the trigger switch 20 in the door control switch feeds back the state of the door body 80 being opened to the controller, and the controller cuts off the power supply of the heating tube to avoid the user being scalded or electrocuted. Of course, the door control switch in the present embodiment is not limited to be applied to the oven, but can also be applied to the refrigerator, microwave oven, electric steamer, etc., and is used to obtain a switch state of the door body 80 and can output the switch state.

[0034] The door control switch in the embodiment comprises a mounting shell 10, a trigger switch 20, a transmission member 30 and a biasing member. The trigger switch 20 is specifically mounted on the mounting shell 10, and the trigger switch 20 is provided with a switch contact 21 which can trigger the trigger switch 20; the transmission member 30 is movably arranged on the mounting shell 10 and has a first working position abutting against the switch contact 21 to trigger the trigger switch 20 and a second working position away from the switch contact 21; the biasing member cooperates with the transmission member 30 and has a biasing force to make the transmission member 30 in the first working position; wherein the transmission member 30 is driven by the door body 80 to overcome the biasing force and move away from the switch contact 21 to the second working position when the door body 80 is closed. Further, when the door body 80 is opened, the transmission member 30 is in the first working position abutting against the switch contact 21 by the biasing force of the biasing member, and when the door body 80 is closed, the transmission member 30 is driven by the force of the door body 80 to overcome the biasing force and move away from the switch contact 21 to the second working position. Compared with the prior art in which the force of the door body 80 directly acts on the switch contact 21, the biasing force of the biasing member is more stable, which can ensure that the switch contact 21 can be pressed, and the trigger switch 20 will not be subjected to a large force when the door is closed, thereby prolonging the service life of the door control switch and making the detection of the opening and closing state of the door body 80 more reliable and stable.

[0035] The biasing member in the embodiment is an elastic member abutting against the transmission member 30 and the mounting shell 10, and is more specifically a spring 40. The transmission member 30 abuts against the switch contact 21 under the elastic force of the elastic member, and at this time the signal output by the trigger switch 20 is a signal that the door body 80 is opened. Of course, the biasing member can also be a magnetic element which provides a magnetic force similar to the elastic force of the spring. The trigger switch 20 is specifically a micro switch which has the advantage of high sensitivity but also has the defect of being easily damaged when subjected to a large force. However, when the trigger switch 20 is applied to the door control switch in the embodiment, the defect that the micro switch is damaged when subjected to a large force can be overcome.

[0036] The mounting shell 10 in the embodiment comprises a bottom shell and a cover plate, and the transmission member 30 is slidably arranged in the bottom shell and / or the cover plate, thereby realizing triggering of different switch states of the door control switch in different sliding positions. Of course, the transmission member 30 can also be rotatably arranged on the shell, and in different rotating positions, triggering of different switch states of the door control switch can also be realized.

[0037] As Figures 2 to 5As shown, the transmission member 30 is slidably arranged on the bottom shell, for example, a sliding groove 11 is formed on the bottom shell, the transmission member 30 can slide in the sliding groove 11, and the spring 40 is arranged between the transmission member 30 and the side wall of the bottom shell. When the door body 80 is in the open state, the spring 40 is always in the compressed state, and under the action of the elastic force of the spring 40, the transmission member 30 pushes the switch contact 21 of the micro switch. At the same time, the door control switch in the embodiment is provided with a limiting table 13 on the mounting shell 10, when the transmission member 30 is pushed by the spring 40, the transmission member 30 abuts against the limiting table 13, the limiting table 13 can limit the forward stroke of the transmission member 30, so that the trigger switch 20 can avoid excessive stress under the action of the spring 40 while realizing the pressing of the switch contact 21, further improving the reliability of the door control switch, and improving the service life and user experience of the door control switch.

[0038] As shown in Figure 3 and Figure 4 As shown, when the door body 80 is in the closed state, the door body 80 pushes the transmission member 30 to slide inward, so that it is separated from the switch contact 21, and the spring 40 is further compressed. In the embodiment, the extension stroke of the elastic member is greater than the movement stroke of the transmission member 30 between the first working position and the second working position, so that the transmission member 30 can still move inward by a stroke of X under the condition that the door body 80 is completely closed. The existence of this stroke can avoid that the door body 80 is stopped by the door control switch and cannot be closed, or the door control switch is damaged under certain assembly error, further improving the reliability of the door control switch in the embodiment, and the detection of the open and closed state of the door body 80 is more reliable and stable.

[0039] As shown in Figure 5 For the transmission member 30 in the embodiment, the transmission member 30 includes a trigger part, the door body 80 drives the trigger part to move when the door body 80 is closed to overcome the biasing force, and specifically, the transmission member 30 is formed with a latch structure 31 protruding from the mounting shell 10 on the trigger part, the latch structure 31 is integrally formed with the transmission member 30, so that the whole structure is more reliable. When the door body 80 of the oven is closed, the latch structure 31 is abutted by the door body 80, and then the transmission member 30 is forced to move, thereby triggering the trigger switch 20. The transmission member 30 in the embodiment also includes a avoiding structure 33, which avoids the trigger switch 20 during the movement of the transmission member 30 away from the switch contact 21 to the second working position, so that the transmission member 30 can smoothly overcome the action of the spring 40 to the second working position, avoiding interference with other structures in the structure of the door body 80, and making the reliability of the door control switch better.

[0040] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
