Abstract
Description
[Technical Field]
[0002] This application belongs to the field of household appliance technology, and specifically relates to an oven with a locking function. [Background Technology]
[0004] Ovens are a common cooking appliance widely used in households. Traditional ovens are usually equipped with a door that can be opened by applying a certain amount of external force. Although most ovens on the market now lock automatically during operation and the door cannot be opened directly until the operation is over, the food inside the oven is still being heated at a high temperature. If children are left unattended, they may accidentally pull the door, causing the oven door to open accidentally and resulting in burns or other safety accidents. [Utility Model Content]
[0006] To address the problem that traditional ovens in the prior art may be accidentally opened by children after operation, resulting in burns, this application provides an oven with a locking function.
[0007] This application is achieved through the following technical solution:
[0008] An oven with a locking function includes an oven body, a door that covers the oven body, and a release assembly for locking or unlocking the door to the oven body. The release assembly includes a release member, a locking block disposed on the door and cooperating with the release member through a linkage mechanism, and a locking groove disposed on the oven body for the locking block to be inserted into.
[0009] An oven with a locking function as described above further includes a handle connected to the oven door. The unlocking assembly further includes a first elastic member disposed between the unlocking member and the handle and driving the unlocking member away from the handle, and a second elastic member disposed between the locking block and the oven door and driving the locking block into the locking groove.
[0010] An oven with a locking function as described above, wherein the linkage mechanism includes a gear and a transverse slider, the release member is provided with a first toothed rail, the transverse slider is provided with a second toothed rail that meshes with the first toothed rail through the gear, and the locking block is provided with an inclined push surface that abuts against the transverse slider. When the release member moves toward the handle, the gear drives the transverse slider to push against the inclined push surface, thereby driving the locking block to be pulled out of the locking groove.
[0011] As described above, in an oven with a locking function, the linkage mechanism further includes a push rod disposed on the horizontal slider and parallel to the inclined push surface in the horizontal direction, the push rod abutting against the inclined push surface.
[0012] As described above, an oven with a locking function includes a piston, a third elastic element, and a longitudinal fixing block disposed between the transverse slider and the locking block. The transverse slider has a mounting groove for placing the third elastic element, the piston is slidably disposed in the mounting groove, and the longitudinal fixing block has a protrusion for pushing the piston.
[0013] In an oven with a locking function as described above, when the horizontal slider pushes against the inclined push surface, the mounting groove and the piston move towards the longitudinal fixing block. The protrusion pushes the piston inward along the mounting groove, while the third elastic element is compressed. Under the elastic force of the third elastic element, the horizontal slider moves away from the longitudinal fixing block to reset.
[0014] In an oven with a locking function as described above, the release element is located on the handle facing the door.
[0015] As described above, an oven with a locking function has a limiting post inside the handle and a limiting groove on the release member, or the handle has the limiting groove and the release member has the limiting post. A first elastic member is sleeved on the outside of the limiting post and the limiting groove, and the limiting post is inserted into the limiting groove to allow the release member to move horizontally relative to the handle.
[0016] An oven with a locking function, as described above, includes two doors that close onto the oven body.
[0017] As described above, an oven with a locking function has an arc-shaped surface on the side of the release member facing the oven body that curves toward the handle.
[0018] Compared with the prior art, this application has the following advantages:
[0019] This application discloses an oven with a locking function. By adding a release component to the oven body, the locking and unlocking functions between the oven door and the oven body are realized. After the oven has finished operating, the user needs to operate the release component to pull the locking block out of the locking slot to unlock and open the oven door. This can prevent children from accidentally opening the oven door when unattended, thus preventing burns and improving the oven's safety performance. [Attached Image Description]

Detailed Implementation Methods
[0029] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0030] Please see Figures 1 to 6 An oven with a locking function includes an oven body 1, a door 2 covering the oven body 1, and a release assembly 3 for locking or unlocking the door 2 to the oven body 1. The release assembly 3 includes a release member 31, a locking block 33 disposed on the door 2 and cooperating with the release member 31 through a linkage mechanism 32, and a locking groove 34 disposed on the oven body 1 for the locking block 33 to be inserted.
[0031] This application discloses an oven with a locking function. By adding a release component to the oven body, the locking and unlocking functions between the oven door and the oven body are realized. After the oven has finished operating, the user needs to operate the release component to pull the locking block out of the locking slot to unlock and open the oven door. This can prevent children from accidentally opening the oven door when unattended, thus preventing burns and improving the oven's safety performance.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a handle 4 connected to the door 2. The unlocking assembly 3 further includes a first elastic member 35 disposed between the unlocking member 31 and the handle 4 and driving the unlocking member 31 away from the handle 4, and a second elastic member 36 disposed between the locking block 33 and the door 2 and driving the locking block 33 into the locking groove 34.
[0033] In this embodiment, by adding a handle that cooperates with the release mechanism on the door, and introducing a first elastic element and a second elastic element, not only is the operating feel of the release mechanism optimized, but the stability and durability of the overall structure are also improved. The first elastic element ensures that the release mechanism remains in a position away from the handle when no external force is applied, avoiding accidental operation; while the second elastic element ensures that the locking block always tends to insert into the locking groove, enhancing the reliability of locking, and when no external force is applied, the release mechanism and the locking block are reset under the action of the first and second elastic elements.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the linkage mechanism 32 includes a gear 321 and a transverse slider 322. The release member 31 is provided with a first toothed rail 311, and the transverse slider 322 is provided with a second toothed rail 3221 that meshes with the first toothed rail 311 through the gear 321. The locking block 33 is provided with an inclined pushing surface 331 that abuts against the transverse slider 322. When the release member 31 moves toward the handle 4, the gear 321 drives the transverse slider 322 to push against the inclined pushing surface 331, thereby driving the locking block 33 to be pulled out of the locking groove 34.
[0035] In this embodiment, when the release element moves towards the handle, its first toothed rail drives the second toothed rail on the transverse slider via a gear, causing the transverse slider to move horizontally and push against the inclined push surface on the locking block. Through this synergistic action, the locking block is smoothly pulled out of the locking groove, thereby releasing the locked state of the door. This mechanical linkage design is not only compact and highly reliable, but the meshing linkage between the gear and the first and second toothed rails can be replaced with other linkage structures such as a paddle, as long as it can drive the release element and the transverse slider to move in opposite directions.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the linkage mechanism 32 further includes a push rod 323 disposed on the transverse slider 322 and parallel to the inclined push surface 331 in the horizontal direction, the push rod 323 abutting against the inclined push surface 331.
[0037] In this embodiment, the operational efficiency and stability of the linkage mechanism are significantly improved. When the transverse slider moves under gear drive, the push rod's design reduces contact with the inclined push surface, thereby reducing friction and ensuring that the locking block can be smoothly and reliably pulled out of the locking slot. This not only reduces mechanical wear and extends the service life of the components but also enhances operational accuracy and user experience.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the linkage mechanism 32 further includes a piston 324, a third elastic element 325, and a longitudinal fixing block 326 disposed between the transverse slider 322 and the locking block 33. The transverse slider 322 is provided with a mounting groove 3222 for placing the third elastic element 325. The piston 324 is slidably disposed in the mounting groove 3222. The longitudinal fixing block 326 is provided with a protrusion 3261 for pushing the piston 324.
[0039] In this embodiment, the design of the third elastic element and the longitudinal fixing block provides more efficient and stable mechanical control for the locking and unlocking operation of the oven. When the transverse slider moves and pushes against the inclined surface, the piston is pushed inward by the protrusion of the longitudinal fixing block within the mounting groove, simultaneously compressing the third elastic element. During this process, the elastic potential energy accumulated in the third elastic element will be released after the operation is completed, pushing the piston and transverse slider to reset, enabling the linkage mechanism to quickly and accurately return to its initial state, ensuring smooth operation for the next operation.
[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, when the transverse slider 322 pushes against the inclined push surface 331, the mounting groove 3222 and the piston 324 move towards the longitudinal fixing block 326, the protrusion 3261 pushes the piston 324 inward along the mounting groove 3222, and at the same time the third elastic member 325 is compressed by force, and the transverse slider 322 moves away from the longitudinal fixing block 326 under the elastic force of the third elastic member 325 to reset.
[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the unlocking member 31 is located on the handle 4 facing the side of the door 2.
[0042] In this embodiment, when using the oven, the user typically needs to hold the handle to open the door. The design of the release mechanism allows the user to easily access and operate the release mechanism directly with their fingers or palm while holding the handle, thus unlocking the oven. This avoids the inconvenience of the user having to search for or move to another location to unlock the door, improving ease of use. It also enhances the oven's clean and integrated appearance. The combination of the release mechanism and the handle makes the external mechanical parts of the oven more compact, reducing unnecessary exposed parts and making the oven look simpler and more aesthetically pleasing.
[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the handle 4 is provided with a limiting post 41 and the release member 31 is provided with a limiting groove 312, or the handle 4 is provided with the limiting groove 312 and the release member 31 is provided with the limiting post 41, the first elastic member 35 is sleeved on the outside of the limiting post 41 and the limiting groove 312, and the limiting post 41 is inserted into the limiting groove 312 to allow the release member 31 to move horizontally relative to the handle 4.
[0044] In this embodiment, the cooperation between the limiting post and the limiting groove provides precise guidance and limitation for the horizontal movement of the release component. The first elastic element is sleeved on the outside of the limiting post and the limiting groove, providing both elastic restoring force to the release component and ensuring its stability during movement, preventing displacement or jamming. This mechanical limiting structure not only enhances the reliability and durability of the release operation but also improves the user's feel and experience during operation.
[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, it includes two oven doors 2 that cover the oven body 1.
[0046] In this embodiment, the two cabinet doors can be configured to be opened by an independent release component for each cabinet door, or they can be opened by holding both cabinet doors with both hands and unlocking both release components simultaneously. If either release component is not unlocked, neither or both of the two cabinet doors can be opened.
[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the release member 31 is provided with an arc-shaped curved surface 314 that bends toward the handle 4 on the side facing the oven body 1.
[0048] In this embodiment, when a user grasps the handle and attempts to unlock the door, their fingers or palm naturally contact the curved surface and are guided by the surface to easily apply force to the unlocking mechanism. This ergonomic design reduces the force and precision required by the user during operation, making the unlocking action smoother and less strenuous. Furthermore, the curved surface guides the user's force direction, preventing operational difficulties or failures caused by improper force angles. Simultaneously, the smooth transition of the curved surface reduces any sharp edges or abruptness that the user may experience during operation, providing a more comfortable operating feel.
[0049] The working principle of this embodiment is as follows:
[0050] This application discloses an oven with a locking function. By adding a release component to the oven body, the locking and unlocking functions between the oven door and the oven body are realized. After the oven has finished operating, the user needs to operate the release component to pull the locking block out of the locking slot to unlock and open the oven door. This can prevent children from accidentally opening the oven door when unattended, thus preventing burns and improving the oven's safety performance.
