Description

an oven

technical field

The utility model relates to the field of heating mechanical equipment, in particular to an oven.

Background technique

The heating method of traditional ovens is generally electric heating, which has the disadvantages of high energy consumption, waste of electric energy, and is not environmentally friendly. The manufacturing cost of the existing hot air oven is relatively high, the temperature in the air duct of the oven is difficult to stabilize, and it is difficult to evenly heat the items to be dried, which reduces the utilization rate of heat energy, wastes a lot of energy, reduces the drying efficiency, and reduces The quality of the dried product greatly reduces the reliability of the oven work.

Contents of the invention

The problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a simple structure, low cost, large effective drying area, good drying effect on items, and good temperature control and heat preservation effect, heat utilization High rate oven.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a kind of oven, comprises box body, and the top of described box body is equipped with an exhaust fan, and one side of described box body is equipped with a blower fan, and described exhaust fan The outlet is connected to one end of a ventilation duct, and the other end of the ventilation duct is installed on the box on the same side as the blower, and communicates with the inside of the box to form a thermal cycle system. The other side of the box is provided with a control A temperature box, the inner wall of the box is laid with a U-shaped coil, the U-shaped coil is equipped with heat transfer oil, the inlet and outlet of the U-shaped coil are connected to a temperature control box, and the temperature control box can adjust the heat conduction The heating temperature of the oil, the inside of the box is provided with multi-layer shelves, and trays are respectively placed on the multi-layer shelves.

Further, a heat conduction sheet is provided on the tray.

Further, the tray is net-shaped.

The advantages and positive effects of the utility model are: the utility model has the advantages of simple structure, low cost, large effective drying area, improved drying effect of articles, good temperature control and heat preservation effect, and improved heat utilization rate, thereby The product quality has been improved and a reliable guarantee has been provided for subsequent production.

Detailed ways

An oven, comprising a box body 1, an exhaust fan 3 is installed on the top of the box body 1, a blower fan 2 is installed on one side of the box body 1, the outlet of the exhaust fan 3 is connected with one end of a ventilation duct 4, and the other end of the ventilation duct 4 One end is installed on the box body 1 on the same side as the blower 2, and communicates with the inside of the box body 1 to form a thermal cycle system. The other side of the box body 1 is provided with a temperature control box 5, and the inner wall of the box body 1 is laid with U-shaped Coil 6, U-shaped coil 6 is equipped with heat transfer oil, the inlet and outlet of U-shaped coil 6 are connected to temperature control box 5, temperature control box 5 can adjust the heating temperature of heat transfer oil, and the inside of box 1 is equipped with multi-layer The shelf 7 and the multi-layer shelf 7 are respectively placed with trays 8 .

The tray 8 is provided with a heat conducting sheet.

The tray 8 is net-shaped.

The working process of this example: turn on the power, adjust the temperature of the temperature control box 5 to the required temperature, and preheat the oven; put the items to be dried into the tray 8 of the oven, close the door of the oven 1, and turn on the blower 2 , air is blown into the box 1, the heat transfer oil in the U-shaped coil 6 is heated under the control of the temperature control box 5, and the heat transfer oil exchanges heat with the air in the box 1 to heat the air to the required temperature , and then heat the items to be dried, turn on the exhaust fan 3 during the drying process, and let the heat circulate through the ventilation duct 4; if the items to be dried need a higher temperature, you can adjust the temperature control box 5 to adjust the temperature in the box body 1 . Due to the setting of the temperature control box 5, it can ensure that the oven has a good temperature control and heat preservation effect, which improves the heat utilization rate. Due to the setting of the heat conduction sheet, the effective drying area can be increased, and the drying effect of the articles is improved, thereby improving the product quality. , providing a reliable guarantee for subsequent production.

An embodiment of the present utility model has been described in detail above, but the content described is only a preferred example of the present utility model, and cannot be considered as limiting the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the utility model should still belong to the scope covered by the patent of the utility model.
