DETAILED DESCRIPTION

[0023] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0024] See also Figures 1-8 The present invention provides an oven with an automatically opening door, comprising a housing 10 and a door 20. One side of the door 20 is rotatably mounted on the housing 10. An opening 101 for placing and removing chips is formed on the front sidewall of the housing 10. The door 20 is arranged corresponding to the opening 101, and the opening 101 can be opened or closed by rotating the door 20. In this embodiment, the side of the door 20 that rotates with the housing 10 forms a rotating side 21, and the side of the door 20 that is away from the rotating side 21 forms a free side 22. A pop-up structure 30 is provided on the side of the door 20 and the housing 10 near the rotating side 21, and a locking assembly 40 is provided on the side of the door 20 and the housing 10 near the free side 22. When the locking assembly 40 is in a locked state, the door 20 is locked to the housing 10, and the opening 101 is closed. When the locking assembly 40 is unlocked, the door 20 can be rotated under the action of the pop-up structure 30 to open the opening 101.

[0025] See also Figure 6-8 The pop-up structure 30 includes a fixed sleeve 31, a top post 32, and an elastic member 33. The fixed sleeve 31 is a tubular structure with an opening at one end. The top post 32 cooperates with the fixed sleeve 31. One end of the top post 32 is slidably received in the fixed sleeve 31 along the axial direction of the fixed sleeve 31. The elastic member 33 is installed in the fixed sleeve 31. One end of the elastic member 33 is connected to the bottom wall of the fixed sleeve 31, and the other end of the elastic member 33 is connected to one end of the top post 32. In this embodiment, the elastic member 33 is a spring.

[0026] In this embodiment, the fixed sleeve 31 is fixedly connected to the front side wall of the cabinet 10. When the user closes the opening 101, the user rotates the door 20 toward the opening 101, causing the door 20 to overcome the elastic force of the elastic member 33 and push inward against the top post 32. The top post 32, under pressure, gradually retracts into the fixed sleeve 31 until the door 20 closes the opening 101. Then, the locking assembly 40 is activated to lock the free side 22 of the door 20 to the cabinet 10, thus closing the opening 101. When the locking assembly 40 is unlocked, the restriction on the free side 22 of the door 20 is released, and the top post 32 is reset and pushed outward under the elastic force of the elastic member 33, thereby pushing the door 20 to rotate and open the opening 101.

[0027] In this way, after a chip process is completed, the box door 20 can be automatically controlled to open, which accelerates the dissipation of heat in the opening 101, is conducive to rapid cooling of the oven, shortens the process time, and improves processing efficiency. At the same time, there is no need for the user to manually open the box door 20, avoiding the situation where the user is burned by high temperature when opening the door.

[0028] As a preferred embodiment, the outside of the fixing sleeve 31 is provided with an external thread, and the fixing sleeve 31 is threadedly connected to the box body 10. In addition, the fixing sleeve 31 is completely buried in the box body 10, so that the fixing sleeve 31 will not protrude to the front side wall of the box body 10, thereby preventing the fixing sleeve 31 from affecting the closing of the box door 20.

[0029] Furthermore, one end of the top column 32 away from the elastic member 33 is set to be hemispherical. When the door 20 is closed, the hemispherical end of the top column 32 abuts against the door 20, which can reduce the wear of the top column 32 on the door 20.

[0030] In other embodiments not shown, the fixed sleeve 31 is fixedly mounted on the door 20. At this time, when the door 20 is closed, the top column 32 is abutted against the front side wall of the box body 10 and retracts into the fixed sleeve 31 under the pressure of the box body 10. In this way, the door 20 can also close the opening 101 by overcoming the elastic force of the elastic member 33, and after the locking assembly 40 is unlocked, the top column 32 automatically pops out, thereby opening the door 20.

[0031] Please refer again Figure 1 、 Figure 2The locking assembly 40 includes an electromagnet 41 fixedly mounted on one side of the free side 22 of the box door 20. The box body 10 is made of a magnetic material. The electromagnet 41 can adsorb the box body 10 when energized. When the box door 20 is closed, after the box door 20 closes the opening 101, the electromagnet 41 is energized. The energized electromagnet 41 generates magnetism and magnetically adsorbs the box body 10, thereby locking the box door 2 on the box body 10. When the box door 20 needs to be opened, the electromagnet 41 loses power and can be separated from the box body 10. The box door 20 will automatically open the opening 101 under the push of the top column 32. In this embodiment, the box body 10 is made of steel plate. In this embodiment, two electromagnets 41 are provided on one side of the box door 2, which jointly adsorb the box body 10, thereby improving the locking stability.

[0032] The locking assembly 40 also includes a rotation and compression cylinder 42, and the cylinder body of the rotation and compression cylinder 42 is fixedly mounted on the casing 10. When the rotation and compression cylinder 42 is started, the pressing plate 421 of the rotation and compression cylinder 42 can be moved close to / away from the door 20 while rotating. The rotation and compression cylinder 42 belongs to the prior art, and its structure and working principle are not described in detail herein. When the electromagnet 41 is energized and adsorbed on the casing 10, at this moment, the rotation and compression cylinder 42 can be started, the pressing plate 421 thereon is driven to move from a vertical state to a horizontal state, and the pressing plate 421 is pressed on the sidewall of the door 20 away from the casing 10, so that the door 20 is pressed and fixed, so that the high-pressure environment in the opening 101 can not open the door 20. And when the door 20 needs to be opened, the rotation and compression cylinder 42 is started first, the pressing plate 421 is moved from a horizontal state to a vertical state, and the electromagnet 41 can be controlled to lose power, so that the door 20 is automatically opened.

[0033] In this embodiment, before starting the rotary pressing cylinder 42, the box door 20 is preliminarily locked on the box body 10 by the electromagnet 41, avoiding obstruction of the movement of the pressure plate 421 when the box door 20 and the box body 10 are not tightly fitted, and effectively ensuring that the pressure plate 421 moves accurately into position.

[0034] In this embodiment, a chain 50 is detachably connected between the housing 10 and the free side 22 of the door 20. One end of the chain 50 is fixedly connected to the door 20, and the other end of the chain 50 is detachably hooked to the housing 10 via a hook (not shown). In this way, the connection of the chain 50 can limit the opening angle of the door 20 during the heat dissipation process of the oven, preventing the door 20 from opening too wide and colliding with the user or other objects. When it is necessary to remove or place chips, the hook of the chain 50 can be removed, allowing the door 20 to fully open the opening 101 for easier operation. Of course, it is understandable that in other embodiments, one end of the chain 50 is fixedly connected to the housing 10, and the other end of the chain 50 is detachably hooked to the door 20.

[0035] Further, see Figure 4 An ionizing wind bar 60 is mounted on the front sidewall of the oven body 10. It is vertically positioned on the free side 22 of the oven door 20, with its air outlet facing the oven door 20. When the oven door 20 is open to dissipate heat, the positive and negatively charged airflow generated by the ionizing wind bar 60 flows from the free side toward the opening 101 through the air outlet. At this point, the positive and negative charges on the oven surface are neutralized by the positive and negative charges in the airflow, thereby eliminating static electricity. The ionizing wind bar 60 is conventional, and its structure and operating principle will not be further described here.

[0036] In the oven with automatic door opening of the present invention, when a chip process is completed, the user can first start the rotary pressing cylinder 42 to separate the pressure plate 421 from the door 20, and then de-energize the electromagnet 41. At this time, the locking relationship between the door 20 and the box body 10 is released, and the door 20 can automatically spring open under the action of the top column 32 to open the opening 101, which is conducive to rapid cooling of the oven, shortens the process time, and improves processing efficiency. At the same time, there is no need for the user to manually open the door 20, avoiding the situation where the user is burned by high temperature when opening the door.

[0037] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
