Abstract
Description
Technical Field
[0001] The utility model relates to an oven, in particular to an oven with an independent control heating unit. Background Art
[0002] With the development of technology, people use ovens to bake food. An oven is a sealed electrical appliance used to bake food or dry products. An oven is an electrothermal appliance that uses the radiant heat emitted by electrothermal elements to bake food. It is usually used to make roasted chickens, roasted ducks, baked bread, pastries, etc. According to the different needs of baked food, the temperature of the oven is generally controlled within the range of 50-250°C. Since the existing ovens have relatively single functions and cannot automatically control the temperature or control the temperature of the local heating area during the baking process, the temperature can only be adjusted manually during the baking process of food. It is relatively difficult to control the baking quality in the absence of monitoring, which greatly affects the taste of the baked food. The baked food usually has an irregular shape, and the oven can only heat the whole inside, resulting in uneven heating of foods with different shapes, which greatly affects the baking effect of the food. Summary of the Invention
[0003] The purpose of the utility model is to provide an oven with an independent control heating unit. The oven with an independent control heating unit effectively solves the problem of the relatively single function of the traditional oven, provides heating units with multiple independent heating zones, and controls the temperature of each independent zone through a control circuit. A temperature measuring probe is provided in each zone, and the temperature of each zone is monitored by the temperature measuring probe, so as to achieve independent heating of each different zone of the oven during the baking process of food and perform local temperature control on different positions of the food according to requirements.
[0004] To achieve the above object, the present utility model provides an oven machine with an independent control heating unit, which is composed of a machine shell, a bottom shell, an oven door, a support frame, an electric heating tube, a temperature sensing probe, an AC contactor, and a control circuit board. The machine shell is a rectangular housing. An oven opening is provided on the front surface of the machine shell, and an oven door is installed at the oven opening. An opening for placing the control circuit board is provided on the shell surface of the front of the machine shell, and the control circuit board is installed at the opening for the control circuit board of the machine shell. The bottom of the machine shell is the bottom shell, and a support frame is fixed on the bottom shell surface. The support frame is composed of two groups on the left and right symmetrically erected on the left and right sides of the bottom shell surface. An AC contactor is provided inside the machine shell, and the AC contactor is installed and fixed on the outer side wall surface of the support frame inside the machine shell. The electric heating tube is an M-shaped electric heating tube body, and the electric heating tube is fixedly installed on the inner side surface of the support frame. A tube hole is provided on the support frame panel, and the bottom feet at both ends of the M-shaped electric heating tube are embedded and fixed at the tube hole of the support frame panel. A sensing probe hole is provided on the support frame panel, and the end of the temperature sensing probe is embedded and fixed at the sensing probe hole of the support frame panel. The electric heating tube body is horizontally fixed on the support frame. The electric heating tube on the support frame and the temperature sensing probe fixed below on the support frame form an independent control heating unit. The independent control heating units are distributed on the upper and lower parts of the support frame, and the independent control heating units can be several groups of units arranged horizontally side by side on the support frame.
[0005] Compared with the prior art, the advantages of the present utility model are as follows: The casing of the machine is rectangular in shape. An oven opening is provided on the front shell surface of the casing. The oven opening is the entrance for placing the food to be baked. An oven door is installed at the oven opening. Closing the oven door can prevent the heat energy inside the casing from leaking. The control circuit board on the casing is used to control the operation of the oven. The bottom of the casing is the bottom shell. Support frames are installed on the left and right sides of the inner side surface of the bottom shell. The support frames are used to install and fix the electric heating tube, temperature sensing probe, and AC contactor. The electric heating tube is in the shape of an M-shaped electric heating tube body. Compared with a straight tube, the M-shaped electric heating tube can have a longer heating tube body wound within a limited heating area, achieving the purpose of large heating in a small area inside the oven. The temperature sensing probe on the support frame is used to monitor the temperature of the electric heating tube. If the temperature is too high, it will send a signal to the control circuit board, and then the control circuit board will control the operation of the electric heating tube. The electric heating tube body is horizontally fixed on the support frame. The electric heating tube is horizontally placed to heat the baked food over a larger area. The independent control heating unit is composed of the electric heating tube on the support frame and the temperature sensing probe below. By monitoring the temperature of the electric heating tube through the temperature sensing probe and transmitting the temperature sensing information to the control circuit board, an independent heating control for independent zones of the oven machine is formed to form an independent control heating unit. The independent control heating units are distributed in the upper and lower parts of the oven machine and can be arranged side by side to form several groups of independent units. Each group of independent control heating units monitors and controls the temperature of the area. The control circuit board independently presets and controls the temperature of each heating zone, and can change the temperature of different independent zones according to different baked foods. For example, for cake food, to achieve a golden brown effect on the surface, the upper temperature of the oven can be adjusted to be higher than the bottom temperature to achieve a better baking effect, solving the problem that the original oven could not adjust the temperature. A partition is provided inside the oven casing. The partition is a cylindrical plate surface used to separate the electric heating tube, preventing the baked food from directly contacting the electric heating tube and also facilitating the placement of the baked food on the partition surface. The control circuit board is connected to the AC contactor through a conducting wire, and the control circuit board is connected to the electric heating tube and the temperature sensing probe through a conducting wire. The AC contactor supplies power to the control circuit board, and then the control circuit board outputs an electrical signal to the electric heating tube and the temperature sensing probe, and the control circuit board controls the operation of the electric heating tube and the temperature sensing probe. The control circuit board can control the preset heating temperature of the independent control heating unit. When the specified temperature is reached, the electric heating tube stops working or maintains the existing temperature, or the heating time can be preset through the control circuit board. When the specified time is reached, the heating stops working, or heating can start working at the specified time, achieving the purpose of independent operation of the independent control heating unit for each zone of the oven machine, so as to bake better food.
