Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to a tabletop oven. Background Technology

[0002] With economic development and the continuous improvement of people's living standards, the demand for luxury goods such as gold and silver jewelry is increasing. Moreover, due to the individual needs of different people, they often hope to have a unique and exquisite piece of gold and silver jewelry. Therefore, jewelry manufacturers need to process gold and silver jewelry with various techniques to create different styles and designs.

[0003] Traditional gold and silver jewelry includes K-gold jewelry. The processing steps for K-gold jewelry are as follows: gold import, wax molding, tree planting, powder filling and molding, powder matting, material preparation, casting, tumble polishing, mold finishing, gold frying, grinding machine polishing, engraving, edge finishing, polishing, inspection, and finished product warehousing. When matting with powder, the wax tree with powder is placed together with the steel cylinder in an electric oven to heat and remove the wax (high temperature volatilization) so that the powder temperature reaches the K-gold casting temperature (about 680°C), which takes about 8 hours. This step requires the operation of an electric oven.

[0004] Existing jewelry ovens are relatively large and inconvenient to use. They cannot monitor the internal temperature in real time, and temperature adjustment is difficult, which fails to meet the baking requirements. Utility Model Content

[0008] A further improvement is that the protective cover is a ceramic protective cover. Ceramic protective covers are environmentally friendly and non-toxic, resistant to high temperatures, highly resistant to dirt, easy to clean, and have a long service life.

[0009] A further improvement is that the heat-insulating sealing gasket is an aluminum silicate fiber gasket. It exhibits high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, low thermal expansion, and excellent heat insulation performance.

[0010] A further improvement is that the control panel is equipped with a display screen, temperature adjustment buttons, and fan speed adjustment buttons.

[0011] A further improvement is that the controller is electrically connected to the electric heating rod, control panel, temperature sensor, and cooling fan, and the controller is electrically connected to the power supply via a power switch.

[0012] A further improvement is that a power plug is provided on the back of the oven body.

[0027] See Figures 1-3 As shown, the technical solution adopted in this specific embodiment is as follows: a desktop oven, including an oven body 1 and an oven door 2. The oven body 1 has a baking cavity 4 in its upper part. The inner wall of the baking cavity 4 is covered with a protective sleeve 3. The protective sleeve 3 has a cavity and is equipped with an electric heating rod 10. The inner wall of the protective sleeve 3 has a heating through hole 31. The bottom of the baking cavity 4 is equipped with a temperature sensor 5 extending out of the protective sleeve 3. The oven body 1 below the baking cavity 4 is equipped with a partition 11. The partition 11 has a cavity and is equipped with a cooling fan 8. The front surface of the oven body 1 corresponding to the partition 11 is equipped with a first heat dissipation vent 15. The two side walls of the oven body 1 corresponding to the partition 11 are equipped with second heat dissipation vents 16. A controller 9 is equipped below the partition 11. The front surface of the oven body 1 below the partition 11 is equipped with a control panel 6 and a power switch 7. The inner wall of the oven door 2 is equipped with a heat insulation sealing gasket 21 corresponding to the baking cavity 4.

[0028] The protective sleeve 3 is a ceramic protective sleeve. Ceramic protective sleeves are environmentally friendly and non-toxic, resistant to high temperatures, highly resistant to dirt, easy to clean, and have a long service life.

[0029] The heat-insulating sealing gasket 21 is an aluminum silicate fiber gasket. It is resistant to high temperatures, has good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, small thermal expansion, and good heat insulation performance.

[0030] The controller 9 is electrically connected to the electric heating rod 10, the control panel 6, the temperature sensor 5, and the cooling fan 8. The controller 9 is also electrically connected to a power source via a power switch 7. The controller is a common adjustable temperature controller.
