The utility model is further described below with reference to the accompanying drawings:

The oven generally includes a cabinet body in which a heating element is provided to heat and bake food materials placed therein, and a door for closing or opening a baking space in the cabinet body to place or take out food materials, and a handle is commonly provided at the door to facilitate user operation.

Depending on the application scenario, ovens may be broadly classified into household ovens and commercial ovens, wherein the door handle of a household oven is typically used only as a handle, i.e., only to pull the door to a user, because the volume of the household oven is relatively small and the frequency of continuous use is low, so that when the oven is used in combination with the baking volume of the household oven, the door can be reliably closed by directly closing the door without separately providing a door lock. However, in the commercial oven, because the volume of the oven is relatively large and the oven is frequently used continuously, the door of the commercial oven is usually opened by a side door (if the door is opened by an upper door in the household oven, the opened door extends out of the operation table when the door is opened, thus preventing the user from being inconvenient to use the door close to the door). However, in the case of using the side door, since the door of the commercial oven is large, there is a problem that the door is not firmly closed at one side after the door is closed, and thus it is necessary to add a door lock structure to the door.

With the added door lock structure, there are a lot of door locks and handles respectively provided at the door, but the handles are provided separately from the door locks, so that the user is complicated to operate when using the door locks. In this regard, it has been proposed to integrate the handle with the door lock, but currently the handle with the door lock is rotated, i.e., the door is opened or closed by rotating the handle clockwise or counterclockwise. The disadvantage of this construction is that the use of the handle in a rotary manner is limited in the type of handle, for example, given the straight profile of the handle, it is very inconvenient for the user to rotate the handle. Based on the above practical difficulties, it is desirable to optimize the handle structure of a door, particularly for commercial ovens that employ side-opening doors.

Example 1

As shown in fig. 1 to 4, the present embodiment provides a door lock structure, including:

The door lock assembly 1, the door lock assembly 1 is installed in the inboard of the handle 2 of chamber door (not shown in the figure), and the handle 2 inboard is equipped with the connecting piece that links to each other with door lock assembly 1, and the connecting piece forms the door lock follow-up center of door lock assembly 1 with the inboard junction of handle 2, and the handle 2 inboard is kept away from door lock follow-up center department and is equipped with handle center of rotation. In this embodiment, in order to expand the type of the adapted handle 2, the handle is operated in a snapping manner, that is, the handle 2 is snapped outward to open the door with the plane of the door as a reference, so that the axis of the handle rotation center is parallel to the door. Furthermore, in order to facilitate the operation of the user, the door lock can be opened together when the handle 2 is broken, and a door lock follow-up center is formed at the connecting piece connecting the door lock assembly 1 and the inner side of the handle 2, so that when the handle 2 is broken by the user, the connecting piece connected with the handle 2 can move along with the handle, and further the door lock assembly 1 connected with the handle 2 is driven to move so as to release the locking of the door.

Specifically, in this embodiment, as shown in fig. 1, the handle rotation center may be disposed near the lower portion of the inner side of the handle 2, and the door lock follower center is disposed near the upper portion of the inner side of the handle 2, in which case, when in use, the user may pull the handle 2 outward from above the handle 2 to open the door, and of course, in other variations of this embodiment, the user may pull the handle 2 outward from other directions of the handle 2, for example, the handle rotation center may be disposed near the upper portion of the inner side of the handle 2, and the door lock follower center may be disposed near the lower portion of the inner side of the handle 2, and at this time, the user may pull the handle 2 outward from below the handle 2 to open the door.

In addition, the connecting piece is designed to connect the door lock assembly 1 with the inner side of the handle 2, and the connecting piece can be used for compensating different movement displacement amounts of the door lock assembly 1 and the handle 2 when the handle is broken by the handle caused by different positions, and meanwhile, the door lock assembly 1 can be driven to reliably move through power transmission of the connecting piece, so that the door lock assembly 1 can be smoothly unlocked by the handle 2.

The door hook component 4 is arranged on one side of the box body (not shown in the figure) facing the handle 2, when the box door is closed, the door hook component 4 is matched with the door lock component 1 to lock the box door, and when the box door needs to be opened, the handle 2 is pulled to rotate outwards along the handle rotation center to drive the door lock component 1 to rotate outwards along the door lock follow-up center to be separated from the door hook component 4.

In this embodiment, the door of the door lock assembly 1 and the box body of the door hook assembly 4 may be a steaming oven, a wind oven, a flat oven, a fermenting oven, a microwave oven, etc. in the baking appliance. The door lock assembly 1 and the door hook assembly 4 may be engaged, clamped, and overlapped, which is not particularly limited in this embodiment.

In the door lock structure of this embodiment, when the door is kept in a closed state, the door can be locked by using the door lock assembly 1 mounted on the inner side of the handle 2 and the door hook assembly 4 mounted on the box body, so as to ensure that the box door reliably closes the box body, and avoid heat loss in the box body during baking. When the door is required to be opened to put food to be baked, or the food is taken out after baking is finished, the handle 2 is outwards turned around the handle turning center by outwards breaking the handle 2, and meanwhile, the door lock assembly 1 arranged on the inner side of the handle 2 is driven to outwards turn around the door lock following center, so that the door lock assembly 1 is separated from the door hook assembly 4, the locking of the door can be released, and then the door is opened. That is, when the door lock structure of the embodiment is used, the door can be opened only by pulling the handle, and the user does not need to independently open the door lock and pull the handle, so that the convenience of the user operation is improved. In addition, the door can be opened by means of the handle 2 being broken, so that the handle 2 in various forms can be adapted, and particularly, for the handle 2 with a straight outline, the comfort in the operation of a user can be improved by operating the handle 2 in a breaking manner, so that the market competitiveness of a product is improved.

As shown in fig. 2 and 3, the door lock assembly 1 comprises a lock catch 11, the door hook assembly 4 comprises a lock seat 41, the lock seat 41 is provided with a lock hook 42 matched with the lock catch 11, and one side of the lock seat 41 facing the lock catch 11 is provided with a guide inclined surface 43. When the door needs to be closed to be locked, under the guiding action of the guiding inclined plane 43, the lock catch 11 can enter the lock hook 42, so that the locking cooperation of the door lock assembly 1 and the door hook assembly 4 can be realized.

As shown in fig. 4, the door lock assembly 1 further includes a restoring member 8, and the restoring member 8 is configured to provide a restoring force for pushing the door lock assembly 1 to return to an original state after the handle 2 is released. Taking the initial state handle 2 shown in the attached drawing as an example, when the handle 2 is required to be opened and the door is outwards broken, the handle 2 is in an outwards inclined state, on the basis, by designing the reset piece 8, torsion springs, springs and the like can be adopted, under the action of reset force, after the door is opened and the handle 2 is released, the door lock assembly 1 can be pushed to recover to the initial state, and the door lock assembly 1 is connected with the inner side of the handle 2 through the connecting piece, so that the handle 2 can be driven to recover to the vertical state.

In this embodiment, when the door is opened and needs to be re-closed again, for example, the door is closed to bake after the door is opened and the food is put into the door, the reset force of the reset piece 8 is utilized to restore the handle 2 and the door lock assembly 1 which are broken off when the door is opened to the initial state, and the guide inclined plane 43 in the door hook assembly 4 is utilized to directly push the handle 2 when the door is closed, so that the lock catch 11 can enter the lock hook 42 to complete the locking of the door, the trouble that the user is still required to break off the handle 2 when the door is closed is avoided, the operation is more convenient, and especially in the scene of frequent use of the commercial oven, the advantage of convenient operation is more obvious.

The connecting piece is connected with the middle part of the door lock frame 12, a first rotating shaft 13 is arranged on one side of the door lock frame 12 close to the handle 2, and a lock catch 11 is arranged on one side of the door lock frame 12 far away from the handle 2. Thus, when the user pulls the handle 2 to drive the connecting piece to move, the connecting piece further drives the door lock frame 12 connected with the connecting piece to rotate around the first rotating shaft 13, and then the lock catch 11 arranged on the other side of the door lock frame 12 rotates along with the door lock frame to be separated from the door hook component 4, so that the locking of the door is released.

Specifically, as shown in fig. 3, the lock catch 11 adopts a roller structure, the roller is rotatably connected with the door lock frame 12, and the lock hook 42 is provided with an arc groove adapted to the roller. In this way, the lock catch 11 is in contact with the door hook component 4 in a rolling friction manner during the moving cooperation of the door of the switch box, so that on one hand, the smoothness of the action can be improved, and on the other hand, the service life of the components can be prolonged. For example, when the door is required to be closed, rolling friction is formed between the lock catch 11 and the guide inclined surface 43 in the form of a roller, and when the door is opened, rolling friction is also formed between the lock catch 11 and the arc-shaped groove in the lock hook 42, so that smooth action can be realized and abrasion between parts can be reduced. Of course, the lock catch 11 forming rolling friction can also be in other forms, such as a rotating sleeve, a roller and the like, and the lock catch can be flexibly selected according to the needs. In addition, in other variations of the present embodiment, the lock catch 11 and the door lock frame 12 may be fixedly mounted, that is, engaged in the form of sliding friction when the door is opened and closed.
