technical field

The invention belongs to a device for semiconductor cooling/heating fruit juice/ice cream, in particular to a device for cooling/heating a heat preservation bucket by using a semiconductor refrigeration/heating chip. Combination structure of male and female plugs.

Background technique

A juicer is a household appliance commonly used to squeeze foods such as fruits or vegetables. It is widely used because the squeezed fruit juice or vegetables are not processed by chemical antisepsis to keep the original flavor and are easily absorbed by the human body. However, the squeezed juice is generally collected in a normal-temperature container, and the temperature cannot be changed in real time according to people's preferences, which cannot satisfy people's taste. When making ice cream, put the fruits and pastries in the refrigerator first, and take them out when the temperature is low; or put the ice cubes made in advance into the ice cream machine and stir them, which will take a long time to make and the food will be easily oxidized and stale. Or other heating equipment needs to be replaced when the temperature needs to be raised and heated in winter. The juice extractors currently on the market often have a single function, which cannot satisfy people's needs that one machine includes multiple comprehensive functions.

If semiconductor refrigeration/heating chips are added to the insulation barrel, especially at the bottom, for cooling/heating of the insulation barrel, the purpose of changing the temperature can be achieved. At the same time, if the stirring function is added to the heat preservation bucket, the effect of making ice cream can be formed. With the continuous improvement of the performance of semiconductor chips, the practical application of the present invention becomes a reality. Under this background, the present invention emerges as the times require.

The thermal insulation material is pasted around the inner tank of the thermal insulation barrel, as well as the semiconductor refrigeration/heating chip and the outside of the semiconductor heat dissipation chip.

The heat sink is pasted under the semiconductor heat dissipation chip.

The heat dissipation fan is located at the bottom of the heat preservation bucket, and the radiator and the heat dissipation fan can also be placed on the side. There are air inlets and outlets on the bottom or the side, and the heat dissipation fan is connected to the power supply.

The stirring motor is connected to drive the stirring paddle to rotate and is fixed on the upper cover, and there is a detachable structure between the stirring paddle and the upper cover.

Beneficial effects of the present invention:

The present invention can realize the purpose of changing the fruit juice temperature according to its own needs by adding semiconductor cooling/heating chips for cooling/heating of the heat preservation barrel. The discomfort caused by the influence of the external temperature when people drink fruit juice in different seasons is avoided. After semiconductor refrigeration/heating, the temperature of the insulation barrel can be adjusted, and the insulation material or vacuum layer can keep the insulation barrel warm. People can drink hot fruit juice in winter and ice-cold fruit juice in summer, thus changing the temperature treatment method of traditional fruit juice and meeting people's needs. At present, ice cream machines that use semiconductor refrigeration on the market generally have the production process of first putting the raw materials used such as fruits and pastries in the refrigerator to cool them down, and then taking them out and putting them into the ice cream machine for stirring when the temperature is low. Due to the poor cooling/heating effect of semiconductors, the entire production time takes about 80 minutes. Since the fruit is placed in the refrigerator and the ice cream is made for a long time, the food will be oxidized when it is in contact with the air for a long time, resulting in the loss of nutrients. Through performance improvement and electrical optimization measures, the present invention uses a thermal insulation barrel to make ice cream, and the cooling/heating performance is greatly improved, and the temperature for making ice cream from food can be reduced by about 25°C in about a minute, which shortens the production time and ensures Fresh taste and nutrition of fruit. As a semiconductor refrigeration/heating fruit juice and ice cream integrated device, the present invention has the advantages of novel structure, high-efficiency refrigeration/heating, low cost, low noise, high reliability, simple operation and maintenance, etc., and is easy to realize large-scale production. Therefore, the application field of the present invention is relatively wide, and the market application prospect is good.
