Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a door-controlled switch trigger structure and a household appliance. Background Art

[0002] Existing door-controlled switches use an elastic pressing structure to trigger a switch function, and are often used in household appliances, such as a door switch for a disinfection cabinet, a door switch for an oven, and the like.

[0003] Among them, linear direct abutment is often used as the triggering method for door-controlled switches. In this triggering method, the rebound force of the door-controlled switch can easily cause the corresponding side of the cabinet door to open too much, making the opening and closing degrees of the left and right sides of the cabinet door and the door frame inconsistent. At the same time, the switching stroke of the door-controlled switch is short, resulting in unreliable triggering of the door-controlled switch. Utility Model Content

[0004] To solve the above technical problems, the present application further improves the existing door-controlled switch trigger structure, in order to obtain a switch structure with small rebound force and more reliable triggering. One purpose of the present utility model is to provide a new door-controlled switch trigger structure, and the second purpose is to provide corresponding household appliances.

[0005] The specific technical solution is described below:

[0006] A gate-controlled switch trigger structure, comprising:

[0007] The door-controlled switch is provided with a trigger member, and the trigger member has a first movable direction in which elastic extension is provided;

[0008] The movable member is provided with a trigger surface, and the trigger surface has a second moving direction of forward movement;

[0009] The first moving direction and the second moving direction are interlaced with each other, and at the interlaced position, the trigger surface at least partially faces the first moving direction and triggers the trigger member.

[0010] In the above technical solution, the trigger member is usually a rod-shaped object. Since the two movable directions are staggered, the trigger surface does not directly and positively act on the end of the trigger member, but acts on the trigger member obliquely with a partial force component, which makes the stroke of the trigger member longer, the contact between the trigger surface and the trigger member is smoother, and the switch operation is more reliable;

[0011] Conversely, the rebound reaction force of the trigger member also acts on the trigger surface in the form of a partial force component. Therefore, the reaction force of the trigger member is mitigated, which greatly reduces the opening effect of the door-controlled switch on the cabinet door on its side, making the opening and closing areas of the left and right sides of the cabinet door consistent with the door frame.

[0012] Preferably, the first activity direction and the second activity direction are perpendicular to each other. As a common and easily implemented method, it is further preferred that the first activity direction is vertically upward, the second activity direction is horizontal, the trigger surface is a plane, and the angle α between the trigger surface and the horizontal plane is 100 to 170°, so as to obtain a more reliable triggering effect.

[0013] Preferably, the above-mentioned door-controlled switch trigger structure further includes: a support member, which is provided with a support surface providing a mounting basis, and the door-controlled switch and the movable member are respectively connected to the support surface.

[0014] Further preferably, the door-controlled switch is connected to one end of the support surface via a fixing member;

[0015] The movable part is connected to the supporting surface via a sliding bracket. At this time, the assembly of the sliding bracket can be completed independently without being affected by the position of the door-controlled switch, and the disassembly, installation and maintenance of the drawer are more convenient.

[0016] More preferably, the fixing member is provided with a fixing installation hole which passes through from top to bottom, and an annular fixing installation seat is provided on the outer periphery of the fixing installation hole; the door-controlled switch part passes through the fixing installation hole and is clamped with the fixing installation seat to form a stable door-controlled switch assembly structure;

[0017] The sliding bracket is slidably connected to the supporting surface via a slide rail to form a linear sliding structure.

[0018] Further preferably, it also includes:

[0019] A door frame, wherein the door frame is provided with a sliding through hole;

[0020] The sliding through hole is formed with an opening through which the sliding bracket slides in and out.

[0021] Preferably, the trigger surface is arranged at one end of the movable member, and the other end of the movable member is provided with a connecting portion, and the connecting portion is fixedly connected to the supporting surface.

[0022] Further preferably, a trigger member pressure plate is provided between the trigger surface and the connecting portion, and the trigger member pressure plate triggers the door-controlled switch by pressing the trigger member;

[0023] At this time, the elastic force of the trigger member will hardly form a component force along the sliding direction of the slide rail, and the best effect is that the opening and closing degrees of the left and right sides of the drawer tend to be consistent.

[0024] A household appliance having a gate-controlled switch trigger structure as described in any of the above technical solutions.

[0025] In summary, the technical solution described in the utility model has the following main beneficial effects:

[0026] Compared with the prior art, the trigger structure in the technical solution of the utility model can extend the stroke of the trigger member, the contact between the trigger surface and the trigger member is smoother, and the switch operation is more reliable;

[0027] It can also significantly reduce the force of the door-controlled switch on the cabinet door on its side, so that the opening and closing degrees of the left and right sides of the cabinet door and the door frame tend to be consistent.

[0028] For a sliding structure with a drawer, the trigger structure described in the utility model allows the assembly of the sliding bracket to avoid the influence of the door switch's position, making the disassembly, installation and maintenance of the drawer more convenient.

[0029] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention is further explained with reference to the following embodiments:

[0044] The core technical problem faced by the technical solution of the embodiment of the present application comes from the inventor's accurate understanding of the prior art. Therefore, how to extend the stroke of the trigger member, make the switch operation more reliable, and make the opening and closing degrees of the left and right sides of the cabinet door and the door frame tend to be consistent are technical problems that the inventor urgently needs to solve.

[0045] At the same time, for the door-controlled switch used in the drawer structure, how to make the disassembly, installation and maintenance of the drawer more convenient is also a technical problem that the inventors are trying to solve simultaneously.

[0046] It should be noted that the embodiments do not constitute a limitation on the protection scope of the claims of the utility model. According to the technical concepts provided / proven by the embodiments, all technical solutions that can be reasonably anticipated by technical personnel in the relevant technical field should be included in the protection scope of the claims of the utility model.

[0047] The embodiments are described in detail as follows:

[0048] Example :

[0049] Please refer to the instruction manual Figure 1-9 In this embodiment, a disinfection cabinet is used as a representative and preferred example of household appliances because the disinfection cabinet has both a switch structure of a drawer panel and a slide rail structure for pulling out the drawer.

[0050] In the disinfection cabinet mentioned in the embodiment, first, as a basic door-controlled switch trigger structure, it includes a door-controlled switch 1 provided with a rod-shaped trigger member 1-1, and a movable member 2 provided with a flat trigger surface 2-1;

[0051] Among them, the trigger member 1-1 has the characteristics of elastic expansion and contraction, and has the following Figure 2 The trigger surface 2-1 has a first moving direction a extending upward as shown in the attached figure. Figure 2 The first and second moving directions a and b are interlaced with each other. At the interlaced position, the trigger surface 2-1 touches the trigger member 1-1 in an inclined state and causes the trigger member 1-1 to retract downward. In this embodiment, the included angle α between the trigger surface 2-1 and the horizontal plane is shown in the attached Figure 6 The angle of the mark in the figure is 100~170° to obtain a more reliable triggering effect.

[0052] The above embodiment is a basic technical solution. Since the trigger surface 2-1 acts on the trigger member 1-1 at an angle with a partial force component, the travel of the trigger member 1-1 is extended, the contact between the trigger surface 2-1 and the trigger member 1-1 is smoother, and the switch operation is more reliable.

[0053] From another perspective, the trigger member 1-1 triggers the switch function with an elastic pressing structure, and the reaction force of the spring rebound also acts on the trigger surface 2-1 as a partial force. Therefore, the reaction force of the trigger member 1-1 is dispersed, reducing its force on the drawer (cabinet door) on the side where it is located, making the opening degree of the drawer on the left and right sides and the door frame tend to be consistent.

[0054] The relative relationship between the first movable direction a and the second movable direction b in the above embodiment is easily known to those skilled in the art. Theoretically, as long as the trigger surface 2-1 is staggered and coordinated with the inclined working mode, similar effects can be achieved, and other related embodiments will not be repeated here.

[0055] At the same time, the door-controlled switch trigger structure described in the above embodiment is not limited to application in disinfection cabinets, and technicians in the relevant field can apply it to other household appliances, such as ovens, etc. without having to work creatively.

[0056] In a preferred embodiment, refer to the attached specification Figure 5-9 The disinfection cabinet is provided with a plurality of drawers. In order to match the sliding track of the drawers, the door control switch trigger structure also includes a long strip support member 3. A support surface 3-1 providing an installation basis is provided on one side of the support member 3. The door control switch 1 and the movable member 2 are respectively connected to the support surface 3-1;

[0057] The door switch 1 is connected to one end of the support surface 3-1 close to the inner side of the disinfection cabinet through the fixing member 4, and the movable member 2 is slidably connected to the slide rail structure on the support surface 3-1 through the sliding bracket 5 to form a linear sliding structure. Specifically, the support surface 3-1 is provided with a through hole or a screw hole for installation, and the fixing member 4 can be positioned through the through hole and the screw hole, and then fixed by welding;

[0058] At this time, the sliding bracket 5 is not directly connected to the door-controlled switch 1, so the assembly of the sliding bracket 5 can be completed independently without being affected by the position of the door-controlled switch 1, and the movable part 2 does not exceed the range of the sliding bracket 5 in the height direction, so it will not hinder the movement of the sliding bracket 5, and the disassembly, installation and maintenance of the drawer will be more convenient.

[0059] In this embodiment, the trigger surface 2-1 and the connecting part 2-2 are respectively arranged at the two ends of the movable part 2, and the connecting part 2-2 is used to be fixedly connected with the supporting surface 3-1. Specifically, a positioning blind hole is arranged on the sliding bracket 5 on the supporting surface 3-1, and a positioning through hole is arranged on the connecting part 2-2. The connecting part 2-2 can be positioned by the positioning through hole and the positioning blind hole, and then fixed by welding.

[0060] In a further preferred embodiment, the reference specification Figure 5-6 The fixing member 4 is provided with a fixing installation hole 4-1 which passes through from top to bottom, and an annular fixing installation seat 4-2 is provided on the outer periphery of the fixing installation hole 4-1; the door-controlled switch 1 is partially inserted through the fixing installation hole 4-1 and is clamped on the fixing installation seat 4-2 to form a stable door-controlled switch assembly structure.

[0061] In a further preferred embodiment, the reference specification Figure 7-8 A horizontal trigger member pressure plate 2-3 is provided between the trigger surface 2-1 and the connecting portion 2-2. When in a fully triggered state, the trigger member 1-1 is compressed under the trigger member pressure plate 2-3. At this time, the elastic force of the trigger member 1-1 hardly forms a component force along the sliding direction of the slide rail, and the effect of making the opening and closing degrees of the left and right sides of the drawer tend to be consistent is the best.

[0062] In a further preferred embodiment, the reference specification Fig.10 The door-controlled switch trigger structure also includes a door frame 6, the support member 3 is welded to the door frame 6, and the door frame 6 is also provided with a sliding through hole 6-1 with a rectangular cross-section, and the sliding through hole 6-1 forms an opening for the sliding bracket 5 to slide in and out.
