[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 This utility model provides an embodiment of a uniformly heated and warmed cabinet with hot air circulation, comprising a cabinet body 1. A fixing plate 2 is fixedly connected to the inner wall of the cabinet body 1. The fixing plate 2 mainly supports and connects the entire shelf 3. The side wall of the fixing plate 2 contacts the shelf 3. Multiple slots are opened on the shelf 3 to allow hot air to pass through, satisfying the need for heat preservation of items on different shelves 3. A limiting mechanism is provided on the inner wall of the shelf 3. A guide rod 7 is fixedly connected to the inner wall of the shelf 3. The guide rod 7 allows the movable plate 4 to move laterally, and the movement trajectory will not be affected. The offset occurs because the side wall of the fixed plate 2 has a moving groove 8, the inner wall of the cabinet 1 is provided with a circulation component, and the limiting mechanism includes a moving plate 4. The moving plate 4 passes through and is slidably connected to the inner wall of the shelf 3. The shelf 3 has a corresponding groove for the moving plate 4, which allows the moving plate 4 to move laterally. The right side wall of the moving plate 4 is elastically connected to the shelf 3 through a return spring 6. The left side wall of the moving plate 4 is fixedly connected to an insert 5. The left end of the insert 5 is a protruding part with strong rigidity, which can support the entire shelf 3 and the items.
[0034] Reference Figure 1 , Figure 5 and Figure 6The circulation component includes an exhaust fan 9, which can exhaust the heated air in the cavity of the cabinet 1 back into the cabinet 1. The exhaust fan 9 is located on the inner wall of the cabinet 1. An exhaust fan 10 is located on the inner wall of the cabinet 1. The exhaust fan 9 is located at the lower part of the cabinet 1, while the exhaust fan 10 is located at the upper part of the cabinet 1. The exhaust fan 10 can draw in the air that has exchanged heat with the items and allow the air to enter the cavity of the cabinet 1 for further heating. The inner wall of the cabinet 1 has a cavity, and the inner wall of the cavity is equipped with a heating tube 11. The heating tube 11 is a tubular heating element that converts electrical energy into heat energy and is used to heat various media such as air, liquid, and solid. It is existing technology and will not be described in detail here. There are multiple sets of heating tubes 11, which are evenly distributed on the inner wall of the cavity.
[0035] Reference Figures 2-4 The right sidewall of the movable plate 4 is fixedly connected to one end of the return spring 6. When the movable plate 4 moves to the right, it will compress the return spring 6. When resetting, the elastic force of the return spring 6 will carry the movable plate 4 to reset. The other end of the return spring 6 is fixedly connected to the right inner wall of the shelf 3. The movable plate 4 is slidably connected to the outer wall of the guide rod 7. The insert 5 passes through and is slidably connected to the inner wall of the movable plate 4. The insert 5 can collect the sliding part of the movable plate 4 to meet the subsequent removal of the shelf 3. The insert 5 is inserted into the inner wall of the movable groove 8. The movable groove 8 has multiple slots corresponding to the insert 5, which can allow the protrusions on the insert 5 to be inserted into their slots to limit the entire shelf 3. There are two sets of insert 5, and the two sets of insert 5 are symmetrically arranged on the sidewall of the movable plate 4.
[0036] Working principle: First, when it is necessary to add or remove the shelf 3, simply move the moving plate 4 to the right, taking the insert 5 with it and compressing the return spring 6, so that the insert 5 is retracted into the groove of the moving plate 4. At this time, the shelf 3 can be aligned horizontally, so that the insert 5 coincides with the moving groove 8 on the fixed plate 2. Then, release the moving plate 4 by hand and use the reverse elastic force of the return spring 6 and the manual assistance to move the moving plate 4 to the left, so that the insert 5 enters the moving groove 8 and is inserted into the inner wall groove of the moving groove 8. If it is necessary to remove the shelf 3, simply follow the above operation steps to separate the insert 5 from the inner wall groove of the moving groove 8 and remove the shelf 3 from the cabinet 1. Alternatively, the position of the shelf 3 can be adjusted on the fixed plate 2 according to the above steps.
[0037] When it is necessary to circulate and keep the cabinet 1 warm, simply turn on the external electrical control equipment to heat the heating tube 11, and let the exhaust fan 9 heat the air in the cavity of the cabinet 1. The heated air is then discharged into the cabinet 1 through the exhaust fan 9. As the density of the hot air decreases, it floats upward and passes through the slot of the shelf 3 to exchange heat with the items to complete the heating. The exchanged air will be continuously drawn in by the suction fan 10 and allowed to enter the cavity of the cabinet 1. The heating tube 11 in the cavity heats the air, which is then discharged into the cabinet 1 through the exhaust fan 9 for further heating, thus completing the entire circulation process.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
