A fast constant temperature water preparation device

Abstract

The invention discloses a quick constant-temperature water preparation device which comprises a water pump, wherein an outlet of the water pump is connected with an inlet of a filter through a water inlet manifold; an outlet of the filter is respectively communicated with the head ends of a first branch and a second branch; the first branch is a heating branch which is provided with a hot-type electrothermal module; the second branch is a refrigeration branch which is provided with a thermoelectric refrigeration module; the tail ends of the heating branch and refrigeration branch converge to form a water outlet manifold; the water outlet manifold is connected with an automatic control system; the automatic control system judges whether the water body needs to be refrigerated or heated according to the water temperature of the water outlet manifold and the set water temperature, thereby controlling the water body to enter the refrigeration branch or heating branch; and the water body is refrigerated or heated to obtain the water body with the set water temperature. The quick constant-temperature water preparation device can be used for quickly preparing continuous constant-temperature water flows in different temperature states (low temperature, normal temperature, high temperature and the like). When the water body is refrigerated, the thermoelectric refrigeration module adjusts and distributes the water quantities of the two branches by an electric three-way adjuster, and a by-pass mode is utilized to control the outlet water temperature.

Description

technical field [0001] The invention relates to a rapid constant temperature water production device, in particular to a rapid constant temperature water production device based on thermoelectric refrigeration and instantaneous electric heating. Background technique [0002] With the progress of society and the development of science and technology, the application of constant temperature water is becoming more and more common. In addition to being widely used in enterprises, medical units, colleges, scientific research departments and production units, people's daily life has also begun to have a constant temperature. Water usage needs. For example: when brewing milk powder for infants and young children, the water temperature should be controlled at 40°C; when brewing green tea, the water temperature should be controlled at 80°C; dry white or light red wine should be soaked in cold water at 5°C to 7°C for a period of time before drinking The taste is the best. Existing d...

Problems solved by technology

Existing household water dispensers with three functions of ice water, warm water and hot water cannot realize precise control of water temperature

In addition, when the existing devices produce hot water or cold water, there is a long-term heating or cooling process, which must be prepared in advance or opened for a long time to meet some fast and immediate use requirements. of energy waste
