Description

Technical Field

[0001] This utility model relates to the field of electric hot air furnace technology, specifically a high-efficiency and environmentally friendly electric hot air furnace. Background Technology

[0002] An electric hot air furnace is a device that uses electricity to generate hot air for heating, and it is widely used in industry, agriculture, and households. Electric hot air furnaces convert electrical energy into heat energy through electric heating elements (such as heating wires or heating tubes).

[0003] For example, the high-efficiency and environmentally friendly electric hot air oven with announcement number "CN212911416U" can simultaneously place ten baking trays inside the oven body for baking, improving baking efficiency and saving baking time. Each set of trays is supported by a support plate, making the trays more secure inside the oven body. However, after the electric hot air oven has finished working, when operators need to remove the heated items from inside the oven, they need to open the oven lid and then remove the trays from inside the oven. During this operation, if the oven lid is touched, it will shake, affecting the operator's removal work. In addition, after the oven has finished working, the items on the trays will overflow during heating and stick to the racks, making it inconvenient for operators to clean the racks, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that if the furnace lid is touched during operation, it will shake, affecting the workers' work of taking it out and making it inconvenient for workers to clean the rack, resulting in low work efficiency. Therefore, this invention proposes a high-efficiency and environmentally friendly electric hot air furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an efficient and environmentally friendly electric hot air furnace, including a horizontal plate and an electric hot air furnace body. The upper end of the horizontal plate is fixedly connected to the electric hot air furnace body. An automatic opening structure is provided on the top of the electric hot air furnace body. The inner wall of the electric hot air furnace body is slidably connected to a placement rack. An anti-slip pad is fixedly connected to the end of the placement rack. The interior of the electric hot air furnace body is provided with a disassembly structure.

[0007] Preferably, the automatic lid-opening structure includes a motor, the output shaft of which is rotatably connected to the housing via a bearing, a bent rod is fixedly connected to the outer wall of the output shaft of the motor, a furnace lid is fixedly connected to the end of the bent rod, and an observation window is fixedly connected to the end of the furnace lid.

[0008] Preferably, the motor is fixedly connected to the upper end of the electric hot air furnace body, and the lower end of the outer shell is fixedly connected to the electric hot air furnace body.

[0009] Preferably, the disassembly structure includes a baffle and a round rod. Two balls are fixedly connected to the end of the baffle, and a limiting sleeve is fixedly connected to the end of the round rod. A spring is sleeved on the outer wall of the round rod, and the two ends of the spring are fixedly connected to the electric hot air furnace body and the limiting sleeve, respectively.

[0010] Preferably, the two ends of the baffle are rotatably connected to the electric hot air furnace body via pins, and the outer wall of the round rod is slidably connected to the electric hot air furnace body.

[0011] Preferably, a fan is installed inside the electric hot air furnace body, and multiple support columns are fixedly connected to the lower end of the horizontal plate.

[0012] The present invention proposes a high-efficiency and environmentally friendly electric hot air furnace, the advantages of which are as follows: through the cooperation of the opening structure and the electric hot air furnace body, the motor drives the bent rod to rotate, the rotation of the bent rod drives the furnace lid and observation window to move, opening the furnace lid. When the furnace lid is opened wide enough for the operator to use, the motor is turned off. Then the operator places the tray containing food on the top of the placement rack. The furnace is equipped with multiple sets of placement racks, which can hold multiple trays at a time. After placement, the motor is controlled to reverse, driving the furnace lid to move and close the furnace lid, preventing the operator from hitting the furnace lid during operation and preventing the furnace lid from shaking and affecting the operator's operation.

[0013] With the help of disassembling the structure and coordinating with the operators, when impurities accumulate on the top of the placement rack and need cleaning, the operator moves the baffle. The movement of the baffle moves the ball, which in turn moves the limiting sleeve, compressing the spring and removing the ball from inside the limiting sleeve. Opening the baffle allows the placement plate and anti-slip pad to be removed. After cleaning, one end of the placement plate is aligned with the opening in the electric hot air furnace body and inserted. The baffle is then moved again, moving the ball and inserting it into the limiting sleeve. The spring force ensures that the limiting sleeve and ball are pressed together, completing the installation of the placement plate. The placement plate can then be removed for easy cleaning, improving work efficiency. Attached Figure Description

[0027] See attached document Figure 1-3 And 6-7:

[0028] The disassembly structure 5 includes a baffle 501 and a round rod 503. The two ends of the baffle 501 are rotatably connected to the electric hot air furnace body 2 via pins. Two balls 502 are fixedly connected to the end of the baffle 501. The outer wall of the round rod 503 is slidably connected to the electric hot air furnace body 2.

[0029] Working principle:

[0030] First, move the tray containing the food to be baked near the device to prepare for the baking process.

[0031] Opening the lid:

[0032] Connect the external power supply to the motor 301, start the motor 301 to drive the bent rod 302 to rotate, the bent rod 302 rotates to drive the furnace cover 303 and the observation window 304 to move, opening the furnace cover 303. When the furnace cover 303 is opened wide enough for the operator to use, turn off the motor 301. Then the operator places the tray containing food on the top of the placement rack 4. The oven is equipped with multiple sets of placement racks 4, which can hold multiple trays at a time. After placement, control the motor 301 to reverse, drive the furnace cover 303 to move, and close the furnace cover 303.

[0033] The electric heating elements (such as heating wires and heating tubes) inside the electric hot air oven body 2 are activated to raise the temperature inside the oven. The fan 7 is then activated to draw cold air into the electric hot air oven body 2. The cold air flows through the high-temperature heating elements, absorbs heat, and becomes hot air. This hot air is then blown onto the food to achieve baking and heating. Finally, the air is discharged from the top of the electric hot air oven body 2. After the work is completed, the motor heating elements and fan 7 of the electric hot air oven body 2 are turned off. The motor 301 is a servo motor with a self-locking function. The motor 301 is activated to open the oven cover 303 and keep the oven cover 303 stationary. The operator then removes the tray.

[0034] Cleanup work:

[0035] When impurities accumulate on the top of the placement rack 4 and need cleaning, the operator moves the inner side of the baffle 501 to rotate it. The rotation of the baffle 501 causes the ball 502 to move out of the groove in the electric hot air furnace body 2. The movement of the ball 502 moves the limiting sleeve 505, compressing the spring 504 and removing the ball 502 from inside the limiting sleeve 505. Opening the baffle 501 allows the placement plate 4 and anti-slip pad 6 to be removed. After cleaning, one end of the placement plate 4 is aligned with the opening in the electric hot air furnace body 2 and inserted. The baffle 501 is then moved again, causing the ball 502 to move and insert into the limiting sleeve 505. The spring 504's elasticity ensures that the limiting sleeve 505 and the ball 502 are pressed together, completing the installation of the placement plate 2. This allows for convenient cleaning of the device's interior, improving work efficiency. Regular cleaning of the device's interior is also possible. Figure 3 As shown, the air intake part of the fan 7 is equipped with a filter screen, which can prevent the stains on the inner wall of the electric hot air furnace body 2 from affecting the heating efficiency, reduce the energy wasted during heating, and make it more environmentally friendly.
