Technical Field
The utility model relates to a refrigerator field, especially a refrigerator that has circulation wind channel.
Background
Semiconductor refrigeration, also known as thermoelectric refrigeration, is a refrigeration technology based on the peltier effect principle. The physical principle of the peltier effect is: the movement of charge carriers in the conductor forms a current which, due to the different energy levels of the charge carriers in the different materials, releases excess heat when it moves from a high level to a low level; instead, heat absorption from the outside (i.e., refrigeration) is required. A semiconductor refrigerator, also called an electronic refrigerator, is a product completely different from a common refrigerator in refrigeration principle.
The existing semiconductor refrigerator only has a single air duct inside, and the circulation of the air inside is insufficient, so that the temperature difference exists in partial areas.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that through increasing the extension wind channel in the refrigerator to the air outlet that will extend the wind channel is established by the refrigerator door, increases the route of circulated air, makes the inside wind circulation of refrigerator more abundant, makes the temperature more even in the refrigerator.
The utility model provides an above-mentioned technical problem provides a refrigerator that has circulation wind channel.
The technical scheme of the utility model is that:
the refrigerator with the circulating air duct comprises a box body and a main fan, wherein the main fan is installed in the box body, a main air duct and an extension air duct are arranged in the box body, the main air duct is communicated with an air outlet of the main fan, and the extension air duct is communicated with the main air duct. An extension air channel is added in the refrigerator, and an air port of the extension air channel is arranged beside a refrigerator door, so that the path of circulating air is increased, the air circulation in the refrigerator is more sufficient, and the temperature in the refrigerator is more uniform.
Furthermore, the number of the extending air ducts is at least two, the extending air ducts are respectively arranged at two ends of the main air duct, and air ports of the extending air ducts are respectively arranged on two opposite side surfaces of the inner wall of the box body.
Further, the main air duct is provided with an air port at the main fan. The air port of the main air duct is additionally provided with the extension air ducts, each extension air duct can generate a circulating air, at least two circulating air streams are formed in the refrigerator, the path of each circulating air stream is shorter, and the air volume of each circulating air stream is larger.
Furthermore, the main fan is arranged in the middle of the inner side surface of the inner wall of the box body. The middle fan can make the air quantity of the two circulating air ducts the same.
Preferably, the air conditioner further comprises an auxiliary fan, the auxiliary fan is installed at an outlet of the extension air duct, and the main air duct is communicated with the interior of the box body through the extension air duct. The main air duct is not directly communicated with the box body, so that air of the main fan enters and exits from the extension channel, and the air quantity of circulating air is ensured.
Preferably, the air outlet of the extension air duct is arranged at one end, close to the box door, of the side surface of the inner wall of the box body.
Preferably, the main fan is a circulating fan, the auxiliary fans are arranged on opposite side surfaces, an air inlet of one of the auxiliary fans is communicated with the extending air channel and used for receiving air in the extending air channel, an air outlet of the auxiliary fan is communicated with an air inlet of the extending air channel and used for supplying air into the box body, an air inlet of the other auxiliary fan is communicated with an air inlet of the extending air channel and used for receiving air in the box body, and an air outlet of the auxiliary fan is communicated with the extending air channel and used for supplying air to the extending air channel.
Compared with the prior art, the utility model have following advantage and effect:
1. the utility model discloses increase in the refrigerator and extend the wind channel to the air outlet that will extend the wind channel is established by the refrigerator door, increases the route of circulated air, makes the inside wind circulation of refrigerator more abundant, and the temperature is more even in making the refrigerator.
2. The utility model discloses a main air duct has 2 kinds of designs, provides different circulated air route respectively, can select according to refrigerator size and price of difference.
