Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying technology, specifically an electric heating blower drying device. Background Technology
[0002] An electric heating drying oven, also known as a "drying oven," uses electric heating to conduct circulating drying tests. It is divided into two types: forced air drying and vacuum drying. Forced air drying uses a circulating fan to blow hot air to maintain a balanced temperature inside the oven. Vacuum drying uses a vacuum pump to extract air from the oven, making the atmospheric pressure inside the oven lower than normal, so that the product can be tested in a very clean state. It is a commonly used instrument, mainly used to dry samples, and can also provide the temperature environment required for experiments.
[0003] Chinese utility model patent CN222069133U, published on November 26, 2024, discloses an electric heating drying oven, including a box body with an electric blower fixedly installed inside; a tray rotatably mounted inside the box, on which materials are placed; a heating chamber fixedly mounted inside the box, which is fixedly connected to the air outlet of the electric blower; multiple air outlets evenly opened on the heating chamber, and multiple ventilation holes evenly opened on the tray; the multiple air outlets on the heating chamber all face the tray and correspond to the ventilation holes on the tray; a motor fixedly mounted inside the box, the output end of the motor drivingly connected to a turning component, the output end of the turning component intermittently contacting the materials for turning the materials. This utility model features a heating chamber and a turning component. The heating chamber heats the air blown by the electric blower, accelerating the drying speed, and when the turning component contacts the materials, it turns the materials, resulting in more uniform and thorough drying, thereby improving drying efficiency.
[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: When the objects to be dried are placed into the electric heating drying oven, it is not possible to achieve a quick transfer in one go. It is necessary to put the items in and take them out in small quantities multiple times, which leads to low efficiency. Moreover, when drying continuously for a long time, opening and taking them out wastes heat. Utility Model Content
[0005] The purpose of this invention is to solve the technical problems of existing electric heating forced-air drying ovens, which cannot achieve rapid one-time transfer when the object to be dried is placed into the oven, and require multiple small-scale insertions and removals, resulting in low efficiency. Furthermore, the invention addresses the technical problem of wasting heat during prolonged opening and removal in multiple consecutive drying processes by providing an electric heating forced-air drying device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] The present invention discloses an electric heating blower drying device, comprising an oven with a heating chamber inside; an insulated door movably connected to the oven; a right-angle frame inserted into the heating chamber; a plurality of first shafts inserted into the right-angle frame; parallel arms sleeved on the first shafts; a second shaft inserted into the upper end of the parallel arms; a base plate sleeved on the second shafts; and a plurality of second through slots formed on the base plate.
[0008] Furthermore, the base plate has multiple first fasteners connected by threaded holes; a placement plate is sleeved on the first fasteners; and a first through groove is provided on the placement plate corresponding to the first fasteners.
[0009] Furthermore, a limiting groove is provided on the right-angle frame corresponding to the parallel arm.
[0010] The electric heating forced-air drying device provided by this utility model has the following beneficial effects:
[0011] 1. This utility model forms a deformable and movable rhomboid structure through two first shafts, two parallel arms, two second shafts, and a base plate. This ensures that the base plate remains parallel to the heating chamber and the bottom surface of the oven during movement. When items need to be placed for drying, first open the insulation door, pull the base plate out of the heating chamber, then place a large number of items on the base plate at once, then push the base plate back into the heating chamber, then close the insulation door, start the oven for heating, and after drying, open the insulation door and pull the base plate away from the heating chamber. This allows for the quick transfer of items placed on the base plate after drying.
[0012] 2. This utility model uses a first fastener to fix the placement plate to the upper surface of the base plate, and the position of the placement plate on the base plate can be adjusted, thereby adjusting the height after entering the heating chamber, thus adapting to drying items of different heights.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.
[0022] Please see Figure 1-4 As shown, an electric heating forced-air drying device includes an oven 1 with a heating chamber 3 inside; an insulated door 2 is movably connected to the oven 1; a right-angle frame 4 is inserted into the heating chamber 3; multiple first shafts 5 are inserted into the right-angle frame 4; parallel arms 6 are sleeved on the first shafts 5; second shafts 7 are inserted into the upper ends of the parallel arms 6; a base plate 8 is sleeved on the second shafts 7; multiple second through slots 12 are opened on the base plate 8, forming a deformable rhomboid structure through the two first shafts 5, the two parallel arms 6, the two second shafts 7 and the base plate 8. This ensures that the base plate 8 remains parallel to the bottom surfaces of the heating chamber 3 and the oven 1 during movement. When items need to be placed for drying, first open the insulation door 2, pull the base plate 8 out of the heating chamber 3, then place a large number of items on the base plate 8 at once, then push the base plate 8 back into the heating chamber 3, then close the insulation door 2, start the oven 1 for heating, and after drying, open the insulation door 2 and pull the base plate 8 away from the heating chamber 3, thus allowing for quick transfer of items placed on the base plate 8 after drying.
[0023] The base plate 8 has multiple first fasteners 9 with threaded holes; a placement plate 10 is sleeved on the first fastener 9; the placement plate 10 has a first through groove 11 corresponding to the first fastener 9, and the placement plate 10 is fixed to the upper surface of the base plate 8 by the first fastener 9, and the position of the placement plate 10 on the base plate 8 can be adjusted, so that the height after entering the heating chamber 3 can be adjusted, thereby adapting to drying items of different heights.
[0024] A limiting groove 15 is provided on the right-angle frame 4 corresponding to the parallel arm 6. The rotation range of the parallel arm 6 is limited by the limiting groove 15, so that the placement plate 10 will not fall completely to the ground after being pulled out, which makes it more hygienic and safe. Moreover, the distance to the lower surface of the oven 1 is relatively small, making it more labor-saving and safer to transfer a large number of items to be dried.
[0025] The two ends of the placement plate 10 are threaded with second fasteners 13. The movement path of the placement plate 10 can be restricted by the second fasteners 13, so that when the placement plate 10 is suspended, it can remain stable after a large number of heavy objects are placed on it. After the items are placed, they can be pushed into the heating chamber 3 for drying and heating.
[0026] The second fastener 13 is fitted with a limiting post 14, which restricts the movement path of the placement plate 10. This allows the placement plate 10 to remain stable when a large number of heavy objects are placed on it while it is suspended in the air. After the items are placed, they can be pushed into the heating chamber 3 for drying and heating.
[0027] The width and spacing of the first through groove 11 and the second through groove 12 are the same, so that when the placement plate 10 and the base plate 8 overlap, the first through groove 11 and the second through groove 12 can be aligned, so that hot air can fully contact the items to be dried placed on the placement plate 10 through the first through groove 11 and the second through groove 12, making the drying more uniform.
