Cool and warm water mattress case with low noise, and cool and warm water mattress

Abstract

The invention discloses a cool and warm water mattress case with low noise, and a cool and warm water mattress. The case comprises a water tank, an inner cool and warm conductor, a semiconductor heating and refrigerating sheet, a radiator and a water pump, wherein the inner cool and warm conductor is arranged in the water tank; the semiconductor heating and refrigerating sheet is arranged out of the water tank and is in heat transfer connection with the inner cool and warm conductor; the radiator is arranged out of the water tank and is in heat transfer connection with the semiconductor heating and refrigerating sheet; the water pump comprises a ceramic spindle, a powder metallurgy bearing, a nylon key and an impeller, wherein the powder metallurgy bearing is sheathed to the ceramic spindle; the nylon key is sheathed to the ceramic spindle; the impeller is sheathed to the ceramic spindle and comprises a plurality of arc-shaped fan blades. According to the cool and warm water mattress case with the low noise, and the cool and warm water mattress, the case can cool silently, meanwhile, noise generated in a water pump circulation water process can be lowered, and therefore, the noiseof the cool and warm water mattress can be greatly lowered on the whole.

Description

technical field [0001] The invention relates to the technical field of mattresses, in particular to a low-noise intelligent cold and warm water mattress. Background technique [0002] There are many kinds of electric bed heating products on the market, and products such as electric blankets are more popular. However, when the electric blanket is used, it will generate a strong electromagnetic field, which may cause physical impact on some frail elderly and pregnant women, and the heat of the electric blanket is easy to accumulate, which may cause the local temperature of the electric blanket to be too high and cause damage to the human body. [0003] In view of the defects of electric blankets, mattresses using water as a heat transfer medium have emerged in the industry. Chinese utility model patent CN2413576Y discloses a semiconductor cooling and hot water mattress. The water mattress consists of a water bed body, a plastic soft Tube, micro-pump, semiconductor cooler, hot...

AI Technical Summary

Problems solved by technology

[0005] With the continuous improvement of people's requirements for the quality of life, the above-mentioned problems of hot and cold water mattresses are gradually exposed: the cooling fan installed in the chassis will produce a certain noise, the friction of the water pump's own parts during the water circulation process of the water pump and the water pump The friction between the parts and the water flow will also produce certain noises, which will affect the sleep of users
