Description

Refrigerable soybean milk machine

[technical field]

The utility model relates to a refrigerated soybean milk machine.

[Background technique]

Soymilk makers have now become a more commonly used product in people's families. Many of the current soymilk makers have a heating function. In this way, the heating device can be activated to heat after the soymilk is squeezed, so that people can drink hot soymilk. However, the weather is relatively hot in summer, and many people like to eat cold products and drink cold soymilk. At present, soymilk machines that can be refrigerated are relatively rare in the market. If you want to drink cold soymilk, you need to pour the soymilk from the soymilk machine into a container , and put it in the refrigerator for freezing, it is troublesome to drink cold soy milk. If there is a soymilk machine that can directly refrigerate the squeezed soymilk, it will become a new product that people like. For this reason, the applicant has designed this patent.

[utility model content]

The utility model overcomes the disadvantages of the above technology, and provides a soybean milk machine capable of cooling and convenient to use.

In order to achieve the above object, the utility model adopts the following technical solutions:

A refrigerated soybean milk machine, comprising a base 1, a barrel body 2 fixed on the base 1 and a machine head 3 mounted on the barrel body 2, a control chip 4 and a motor 5 are arranged on the machine head 3 to crush The cutting tool 6 is provided with a semiconductor cooling chip 7 and a fan 8 in the cavity in the base 1, the power input end of the semiconductor cooling chip 7 is connected to a DC power supply, and the cold end surface 71 of the semiconductor cooling chip 7 is connected to the barrel body 2 The outer bottoms are close to each other, the fan 8 is arranged below the hot end surface 72 of the semiconductor refrigeration sheet 7, and the heat dissipation hole 11 opposite to the fan 8 is opened on the base 1, and the control semiconductor refrigeration sheet 7 is arranged on the base 1. On or off refrigeration switch 9 between the power input terminal of the power supply and the DC power supply.

Compared with the prior art, the beneficial effects of the utility model are:

1. When it is necessary to refrigerate the soybean milk in the soybean milk machine, just turn on the refrigeration switch, and the semiconductor refrigeration sheet will start to work. The semiconductor refrigeration sheet will transfer the temperature in the barrel of the soybean milk machine from the cold end surface to the hot end surface, and then the semiconductor refrigeration sheet will be transferred by the fan. The heat of the hot end surface on the refrigerating sheet is discharged to the outside of the soymilk machine, so as to realize the cooling of the soymilk in the soymilk machine, and the cooling is more convenient.

2. The refrigerating part of the utility model has no sliding parts, does not produce a turning effect, and has no vibration and noise during operation, and requires high reliability.

3. It does not need any refrigerant, can work continuously, has no pollution source, has a long service life and is easy to install.

4. The thermal inertia of the semiconductor cooling chip is very small, and the cooling and heating time is very fast. When the hot end has good heat dissipation and the cold end is empty, the cooling chip can reach the maximum temperature difference in less than one minute after being powered on.

5. The temperature difference of the semiconductor refrigeration sheet can be realized from 0°C to a negative temperature of 130°C, and the refrigeration temperature range is relatively large.

[Detailed ways]

Below in conjunction with accompanying drawing and embodiment of the present utility model, further describe in detail:

A refrigerated soybean milk machine, comprising a base 1, a barrel body 2 fixed on the base 1 and a machine head 3 mounted on the barrel body 2, a control chip 4 and a motor 5 are arranged on the machine head 3 to crush The cutting tool 6 is provided with a semiconductor cooling chip 7 and a fan 8 in the cavity in the base 1, the power input end of the semiconductor cooling chip 7 is connected to a DC power supply, and the cold end surface 71 of the semiconductor cooling chip 7 is connected to the barrel body 2 The outer bottoms are close to each other, the fan 8 is arranged below the hot end surface 72 of the semiconductor refrigeration sheet 7, and the heat dissipation hole 11 opposite to the fan 8 is opened on the base 1, and the control semiconductor refrigeration sheet 7 is arranged on the base 1. On or off refrigeration switch 9 between the power input terminal of the power supply and the DC power supply.

When it is necessary to refrigerate the soybean milk in the soymilk machine, just turn on the refrigeration switch, and the semiconductor refrigeration sheet will start to work. The heat of the hot end surface is discharged to the outside of the soymilk machine, so as to realize the cooling of the soybean milk in the soymilk machine, and the refrigeration is more convenient.

The semiconductor cooling chip 7 is also called a thermoelectric cooling chip, which is a kind of heat pump. The semiconductor cooling chip 7 is composed of two ceramic sheets, and there are N-type and P-type semiconductor materials (bismuth telluride) in the middle. The above is connected in series. The working principle of the semiconductor refrigeration sheet is: when a piece of N-type semiconductor material and a piece of P-type semiconductor material are connected to form a galvanic pair, after a DC current is connected in this circuit, energy can be generated. Transfer, the current flows from the N-type element to the joint of the P-type element to absorb heat, and becomes the cold end, and the heat is released from the joint of the P-type element to the N-type element, and becomes the hot end. The size of heat absorption and heat release is determined by the size of the current and the number of pairs of semiconductor materials N and P. Inside the cooling sheet is a thermopile composed of hundreds of pairs of electric couples to achieve enhanced cooling effect.

In addition, by changing the polarity of the direct current, the semiconductor cooling sheet 7 can also be heated, so as to achieve cooling or heating on the same cooling sheet.
