In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0026] refer to Figure 1-Figure 3 As shown, in the embodiment of the utility model, an electric drying box is proposed, including a box body 1, a box door 2, a partition 4, a heating element 7, a transmission element 5 and a driving mechanism 3, wherein the box body 1 is configured as a groove-shaped structure with one side open, the box door 2 is hinged on the open side of the box body 1 and connected to the output end of the driving mechanism 3, and the driving mechanism 3 is configured to drive the box door 2 to rotate to open or close the opening. The partition 4 is used to place materials, and is slidably inserted in a slideway 11 extending in the direction of the opening provided in the box body 1. One end of the transmission element 5 is connected to the box door 2, and the other end is connected to the partition 4, so that when the box door 2 is opened, the partition 4 slides along the direction of the slideway 11 and extends out of the box body 1. The heating element 7 is located in the box body 1, and can generate high temperature after being powered on, which is used to dry the materials in the box body 1.

[0027] The above-mentioned electric drying box uses a driving mechanism 3 to control the opening and closing of the box door 2, and a transmission member 5 is arranged between the box door 2 and the partition 4 for placing materials, so that the partition 4 extends out of the box body 1 as the box door 2 is opened, making it convenient for operators to complete the taking and placing of materials outside the box body 1, and the operation is simple and safe.

[0028] refer to Figure 1 and Figure 2 As shown, the driving mechanism 3 is arranged at the top of the box body 1, and includes a motor 31 and a first connecting rod 32 and a second connecting rod 33 which are hinged to each other. One end of the first connecting rod 32 away from the second connecting rod 33 is connected to the output shaft of the motor 31 fixed on the box body 1, and one end of the second connecting rod 33 away from the first connecting rod 32 is rotatably connected to the box door 2. When the motor 31 rotates, it can drive the first connecting rod 32 to rotate, thereby driving the second connecting rod 33 and the box door 2 to move, so as to realize the opening and closing of the box door 2.

[0029] In order to automatically start the driving mechanism 3 when the operator has a lot of items on his hands, the electric drying box also includes a sensing element that is connected to the motor 31 in communication. The sensing element forms a sensing area near the electric drying box. When the sensing element senses that the operator enters the sensing area or a part of the human body enters the sensing area, it transmits a signal to the motor 31, and the motor 31 starts, thereby driving the box door 2 to open. During the opening process of the box door 2, the operator or a part of the human body exits the sensing area. When the box door 2 needs to be closed, the operator or a part of the human body re-enters the sensing area. After sensing, the sensing element transmits a signal to the motor 31, and the motor 31 starts and rotates in the opposite direction, thereby driving the box door 2 to close. Preferably, the sensing element uses an infrared sensor, and the size of the sensing area formed by it is 30*10mm to reduce the possibility of misoperation. The infrared sensor can be installed at a certain position on the box door 2.

[0030] In this embodiment, the electric drying box also includes a timer that is in communication with the motor 31. The closing time of the box door 2 is used as the starting time, and the required drying time is set as the standard time. When the sensing element senses that the operator enters the sensing area, the interval time between the current time and the starting time is determined. If the interval time is less than the standard time, the driving mechanism 3 is not started, and the box door 2 is not opened; if the interval time is greater than or equal to the standard time, the driving mechanism 3 is started, and the box door 2 is opened, so as to avoid the box door 2 from being opened due to the operator or other personnel mistakenly entering the sensing area, thereby ensuring the smooth progress of the drying operation.

[0031] Of course, the electric drying box can also be provided with an emergency button for controlling the opening and closing of the driving mechanism 3. When an unexpected situation occurs and the box door 2 needs to be opened urgently, the box door 2 can be started by the emergency button, regardless of the set standard time. Or when the driving mechanism 3 fails, the box door 1 can be opened manually using the door handle provided on the box door 1. At this time, the infrared sensor as the sensing element is preferably provided on the door handle.

[0032] refer to Figure 1 and Figure 3 As shown, the transmission member 5 is an elastic push-pull rod, one end of which extends into the slideway 11 and is connected to the partition 4, and the other end is connected to the door 2. When the door 2 moves away from the box body 1, that is, when the door 2 is opened, the elastic push-pull rod bends and pulls the partition 4 to move out of the box body 1. When the door 2 moves toward the box body 1, that is, when the door 2 is closed, the elastic push-pull rod pushes the partition 4 into the box body 1 under the guidance of the slideway 11.

[0033] In some other embodiments, the transmission member 5 can be a connecting rope. In this case, the transmission member 5 can only transmit the power of the door 2 moving away from the box body 1 to the partition 4. When the door 2 is closed, as the door 2 rotates toward the box body 1, the door 2 abuts against the partition 4, thereby pushing the partition 4 to retract into the box body 1.

[0034] refer to Figure 3 As shown, slideways 11 are provided on opposite sides of the box body 1, and opposite sides of the partition 4 are respectively inserted into the corresponding slideways 11 to achieve stable connection with the box body 1. In order to improve the drying efficiency, multiple partitions 4 are arranged in the box body 1 at intervals up and down, based on this, multiple transmission members 5 are arranged in a one-to-one correspondence with the partitions 4. It can be understood that when the transmission member 5 drives the partition 4 to move outside the box body 1, the part extending out of the box body 1 preferably occupies one-third to one-half of itself, so that the operator can place the material on the partition 4 to avoid scalding, and the center of gravity of the partition 4 can be kept in the box body 1 as much as possible to avoid serious deformation of the partition 4 and affect the service life.

[0035] In order to reduce the friction between the partition 4 and the slideway 11, pulleys are further provided on opposite sides of the partition 4, and the pulleys are rollingly connected to the slideway 11 to adjust the sliding friction between the partition 4 and the slideway 11 to rolling friction.

[0036] refer to Figure 1 As shown, in this embodiment, the box body 1 adopts a double-layer design, including an outer insulation layer and an inner insulation layer, and the heating element 7 and the partition 4 are both arranged in the inner cavity of the inner insulation layer. The box door 2 and the box body 1 are made of mirror stainless steel argon arc welding as a whole, and the external dimensions are specifically designed according to the requirements of the material. For example, the outer insulation layer can be set to a rectangle with a length, width and height of 700*600*900mm respectively, and the inner insulation layer is set to 480*380*600mm. And the hinge axis used for the hinge between the box body 1 and the box door 2 is set on the right side of the box body 1, that is, the box door 2 opens from left to right. In order to facilitate the observation of the drying condition of the material in the box body 1, a transparent observation window can also be set on the box door 2.

[0037] Continue to refer Figure 1The heating element 7 is configured as a serpentine electric heating tube, and a plurality of electric heating tubes are arranged on the rear side wall of the inner insulation layer at intervals up and down. The heating element 7 in the box body 1 is 4800 mm long, the arrangement height is 100 mm, and the arrangement length is 480 mm.

[0038] In order to improve the drying efficiency and drying uniformity, the electric drying box in this embodiment also includes a fan 6. Figure 1 As shown, the inner insulation layer and the outer insulation layer are enclosed together to form a closed inner circulation cavity, and an air duct is arranged in the inner circulation cavity, and the two ends of the air duct are respectively connected to the inlet and outlet arranged on the inner insulation layer, and the fan 6 is arranged at the inlet or outlet to form an air flow circulation between the air duct and the inner cavity, so that the temperature in the box body 1 is more uniform. Preferably, the inlet and outlet are respectively arranged at the top and bottom of the box body 1, and the partition 4 is provided with air holes, and the gas circulates vertically in the inner cavity to pass through different partitions 4 to dry the materials on the partition 4. Preferably, the fan 6 adopts a variable speed fan 6, and the frequency of the fan 6 may be adjusted according to different drying requirements. The fan 6 can make the air circulate in the electric drying box, accelerate the heat exchange efficiency between the heating element 7 and the air, and achieve the purpose of rapid drying. Moreover, it can also improve the uniformity of the temperature in the inner cavity, so that the material is dried evenly. As for whether the fan 6 is an exhaust fan or a blower, no specific restriction is made here.

[0039] In this embodiment, reference Figure 3 As shown, the partition 4 is made of stainless steel tubes with a diameter of 0.5 mm, which are staggered and welded, and there are gaps between adjacent stainless steel tubes to form the above-mentioned air holes, so that the air flow can pass through the partition 4 up and down.

[0040] More specifically, the air duct is enclosed by a heat-insulating material disposed in the inner circulation cavity, and the heat-insulating material may preferably be a heat-insulating board.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technical operators in the relevant field, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
