They are now widely used in chemical, electronic communications, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical, aerospace and colleges and universities.

[0003] When using a constant temperature drying oven, the entire inner cavity of the oven is usually heated. When there is less material to be dried, activating all the heating elements to heat the inner cavity of the oven is a waste of electricity. In addition, when only a portion of the material is taken out, the heat in the entire oven is easily diffused outward when the oven door is opened, affecting the environment of other materials and thus affecting the constant temperature drying effect of other materials. Utility Model Content

[0004] In response to the above-mentioned deficiencies in the prior art, the present invention provides an energy-saving constant temperature drying oven, which can activate the heating elements in the corresponding constant temperature chamber according to the amount of material. When there is less material, it is not necessary to activate all the heating elements to heat the entire inner cavity of the box, saving electricity. Multiple horizontal plates separate the multiple constant temperature chambers. When the door of a constant temperature chamber is opened, the temperature of other constant temperature chambers does not change, thereby ensuring that the environment in which the materials in other constant temperature chambers are located does not change.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an energy-saving constant temperature drying oven, comprising a box body, wherein a vertical plate is provided in the box body, a plurality of horizontal plates are provided between the vertical plates and the inner wall of the box body, a constant temperature cavity is formed between each pair of the horizontal plates and between the horizontal plates and the inner wall of the box body, an air inlet cavity is formed between the vertical plates and the inner wall of the box body, a heating element and a temperature sensor are provided on the inner wall of the box body and in each constant temperature cavity, a plurality of motors are provided on the vertical plates at a position corresponding to each constant temperature cavity, the plurality of motors are located in the air inlet cavity and the output ends pass through the vertical plates, a fan blade is provided at the output end of each of the motors, a plurality of ventilation holes are provided on the vertical plates at a position corresponding to each fan blade, an air inlet hole is provided on the top wall of the box body at a position corresponding to the air inlet cavity, a plurality of air outlet holes are provided on the side walls of the box body corresponding to the plurality of constant temperature cavities, a plurality of doors are openably provided on the box body corresponding to the plurality of constant temperature cavities, and a control panel is provided on the box body.

[0006] Preferably, a first filter is provided in the air inlet, and a second filter is provided in each of the air outlets.

A plurality of doors 14 are openably and closably provided on the box body 1 corresponding to the plurality of constant temperature cavities 1-1, and a control panel 16 is provided on the box body 1; a first filter 9 is provided in the air inlet, and a second filter 11 is provided in each of the air outlet holes; a storage plate 4 is provided for horizontal sliding in each of the constant temperature cavities 1-1; a pair of slide bars 12 are provided on both sides of each of the storage plates 4, and a slide groove 13 is provided on the vertical plate 2 and the inner wall of the box body 1 corresponding to the position of each pair of slide bars 12, and the slide bar 12 is horizontally slidably provided in the slide groove 13; a plurality of mounting grooves are provided on the vertical plate 2, and a plurality of fan blades 8 are provided in the plurality of mounting grooves; an observation window 15 is provided on each of the door 14.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] In the present invention, the heating element 5, the temperature sensor 6 and the motor 7 are all connected to the external electrical control system through wires, wherein the temperature sensor 6 can transmit a signal to the control panel 16 according to the temperature it senses, thereby controlling the heating element 5. The above equipment and connection methods are all existing technologies and will not be described in detail here.

[0021] According to the instruction manual Figure 1-2It can be seen that when the present invention is in use, when there are fewer materials to be heated and dried, the box doors 14 (such as two) that can hold a corresponding number of materials are opened, the materials are placed on the horizontal plate 3 or the bottom wall of the box body 1 respectively, the box door 14 is closed, and the heating element 5 and the corresponding motor 7 in the constant temperature chamber 1-1 are started through the control panel 16. The heating element 5 can be a resistance wire. The heating element 5 heats the constant temperature chamber 1-1. When the temperature rises to the set value, it remains constant (the temperature signal is transmitted to the control panel 16 through the temperature sensor 6, and the control panel 16 controls the heating element 5). When the output end of the motor 7 rotates, the fan blades 8 are driven to rotate, and the fan blades 8 move the air in the air inlet chamber 1-2. The air is blown into the constant temperature chamber 1-1 through multiple ventilation holes 10, and the outside air flows into the air inlet chamber 1-2 from the air inlet hole on the box body 1. The air blown into the constant temperature chamber 1-1 discharges the wet steam generated when the material evaporates from the air outlet. When the material needs to be taken out of a certain constant temperature chamber 1-1 after a period of constant temperature drying, the heating element 5 and the motor 7 of the corresponding constant temperature chamber 1-1 are closed, and the box door 14 of the corresponding constant temperature chamber 1-1 is opened to take out the material. Since each constant temperature chamber 1-1 is separated by a horizontal plate 3, when the box door 14 of a constant temperature chamber 1-1 is opened, it will not affect the environment of the materials in other constant temperature chambers 1-1, thereby ensuring that the temperature in other constant temperature chambers 1-1 does not change.

[0022] There is a possible implementation, in which a first filter 9 is provided in the air inlet, and a second filter 11 is provided in each air outlet, and the first filter 9 and the second filter 11 filter impurities such as dust to prevent the impurities from entering the box 1.

[0023] There is a possible implementation, in which a storage plate 4 is horizontally slidably provided in each constant temperature chamber 1-1. When the material is heated at a constant temperature, the material is placed on the storage plate 4. When the material is taken out, the personnel manually pull out the storage plate 4. A handle is provided on the storage plate 4 to facilitate operation.

[0024] There is a possible implementation, when the storage plate 4 slides horizontally, it drives a pair of slide bars 12 to slide in a pair of slide grooves 13, and the slide grooves 13 limit the slide bars 12 to prevent deviation during movement.

[0025] In one possible implementation, a plurality of mounting grooves are provided on the vertical plate 2, and a plurality of fan blades 8 are arranged in the plurality of mounting grooves to prevent the fan blades 8 from touching the material when rotating.

[0026] In one possible implementation, each box door 14 is provided with an observation window 15 through which the condition of the material can be checked.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
