Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a push rod door opening structure. Background Technology

[0002] In the field of home appliances, such as ovens, steam ovens and integrated cooktops, the design of the cabinet door is crucial to the user experience. Traditional cabinet doors are usually connected by torsion spring hinges and a locking mechanism to fix the opening and closing state of the door.

[0003] Currently, when users need to open the cabinet door, they must first operate the latch switch, and then the door will open under the action of the hinge torsion spring. However, the torsion spring hinge can only provide driving force to open to a certain angle, so it is impossible to achieve fully automatic opening of the cabinet door in one operation. The door still needs to be opened manually, which increases the complexity of operation and also affects the user experience to some extent.

[0004] Based on this, in order to optimize the ease of operation of the cabinet doors of existing electrical appliances, we propose a push rod opening structure. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the inability to achieve fully automatic opening of the cabinet door in a single operation, and to propose a push rod door opening structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a push-rod door opening structure, including:

[0008] Guide components, sliding components, and driving components;

[0009] The sliding member is slidably connected to the inner side of the guide member, and the driving member drives the sliding member to move linearly through a transmission structure;

[0010] It also includes a position detection component, and the slider has a trigger part, the position detection component and the trigger part are in contact.

[0011] Furthermore, the guide includes a bracket fixed within the box frame;

[0012] The support has a tubular structure and an opening on its side.

[0013] Furthermore, the sliding member is a rod, and both sides of the rod have guide portions, and the inner hole of the bracket has a sliding groove that is slidably adapted to the guide portions;

[0014] The rod has a rack portion on its side facing the clearance opening.

[0015] Furthermore, the driving component is a motor;

[0016] The transmission structure includes a gear fixed on the end of the motor shaft, the gear being positioned at the clearance opening and meshing with the rack portion for transmission.

[0017] Furthermore, the position detection component includes a fixing plate installed inside the box frame, and two micro switches are installed at a distance from the lower end of the fixing plate. The trigger part slides between the two micro switches and abuts against the trigger ends of the two micro switches respectively.

[0018] Furthermore, a top rod is fixedly installed at the bottom of the sliding member, and a top block is fixedly installed on the free end of the top rod.

[0019] The door opening structure proposed in this utility model has the following advantages: the sliding component is driven by a driving component to move the sliding component, which is used to further automatically open the door during the door unlocking process. This enables the door to open automatically, improves the convenience of operation, and the overall structure design is simple and optimizes the reliability of use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3 As an embodiment of this utility model, a push rod door opening structure is disclosed. Specifically, the push rod structure includes a guide 1, a sliding member 2, and a driving member 3. Of course, the guide 1, the sliding member 2, and the driving member 3 are all placed in the housing.

[0026] The sliding member 2 is slidably connected to the inner side of the guide member 1, and the driving member 3 drives the sliding member 2 to move linearly through the transmission structure 4;

[0027] It also includes a position detection component 5, and the slider 2 has a trigger part 21, and the position detection component 5 is in contact with the trigger part 21.

[0028] In some embodiments, the guide member 1 of the present invention includes a bracket 11 fixed in the box frame; the bracket 11 has a tubular structure and an avoidance opening 12 is provided on its side, specifically the avoidance opening 12 is a rectangular opening.

[0029] Based on the above embodiments, the sliding member 2 in this embodiment is a rod. The rod in this embodiment is preferably an L-shaped structural member. The trigger part 21 is an L-shaped bent part formed on the upper end of the rod. Reinforcing angle irons are provided on both sides of the L-shaped bent part.

[0030] Both sides of the rod have guide portions 22, which are configured as guide protrusions. The inner hole of the bracket 11 has a sliding groove 13 that is slidably adapted to the guide portion 22. The sliding stability of the slider 2 inside the bracket 11 is improved by the sliding cooperation between the guide portion 22 and the sliding groove 13.

[0031] The rod has a rack portion 23 on its side facing the clearance opening 12.

[0032] Furthermore, in this embodiment, the driving component 3 is a motor, which is also installed inside the housing frame; the transmission structure 4 includes a gear fixed on the end of the motor shaft, the gear is located at the clearance opening 12 and meshes with the rack portion 23 for transmission. In specific operation, the motor drives the gear to rotate. Since the gear meshes with the rack portion 23, the forward and backward extension drive of the entire sliding component 2 can be realized.

[0033] Preferably, in this embodiment, the position detection component 5 includes a fixing plate 51 installed in the box frame. Two micro switches 52 are installed at a distance from the lower end of the fixing plate 51. The trigger part 21 slides between the two micro switches 52 and abuts against the trigger ends of the two micro switches 52 respectively. The structure of the micro switches 52 is prior art and will not be described in detail here. Of course, the micro switches 52 are connected to the main control board of the oven. The position of the sliding member 2 is detected by the two micro switches 52 to realize the motion control of the motor.

[0034] It should be noted that, in this embodiment, a top rod 6 is fixedly installed at the bottom of the sliding member 2, and a top block 61 is fixedly installed on the free end of the top rod 6. In this embodiment, the top block 61 can preferably be a high-temperature resistant rubber block, the purpose of which is to achieve flexible contact with the door. Of course, in this embodiment, the top rod 6 and the sliding member 2 can also be detachable, such as threaded connection or snap-fit ​​connection, so as to facilitate the replacement and maintenance of the top rod 6.

[0035] During the opening action, after the cabinet door is unlocked, the torsion spring hinge opens the cabinet door to a predetermined angle, such as opening the cabinet door to a 30° position. Then, the motor is started, and the motor drives the gear to rotate. The gear controls the sliding member 2 to move forward through the meshing rack part 23. The push rod 6 on the sliding member 2 pushes the cabinet door open and continues to move forward. When the trigger part 21 on the sliding member 2 touches the micro switch 52 on the front side, the motor starts to rotate in reverse, so as to drive the gear to rotate in reverse and make the push rod 6 move backward. When it touches the micro switch 52 on the rear side, it returns to the initial position and the motor stops working.

[0036] In summary, the present invention uses a driving component 3 to drive the sliding component 2 to move, thereby automatically opening the door during the door unlocking process. This enables the door to open automatically, improves the convenience of operation, and features a simple overall structure design and optimized reliability.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
