Conversion type water-saving electric assistant rapid heating water supply device and central heating non-central water supply system

Abstract

The invention relates to a conversion type water-saving electric assistant rapid heating water supply device and a central heating non-central water supply system. The conversion type water-saving electric assistant rapid heating water supply device comprises a water flow channel, an electric heating device and a relevant electricity safety protection device, a feeding water over-temperature protector and a discharging water over-temperature protector, wherein the electric heating device is used for heating water flow; the feeding water over-temperature protector is used for controlling whether the electric heating device heats or not to realize the conversion of a hot water source according to feeding water temperature detected near the water inlet of the water flow channel; the discharging water over-temperature protector is used for controlling whether the electric heating device heats or not according to the discharging water temperature detected near the water outlet of the water flow channel; when the feeding water over-temperature protector detects that the feeding water temperature reaches the preset feeding water temperature, the electric heating device stops heating. The invention also provides a corresponding water supply system. The conversion type water-saving electric assistant rapid heating water supply device disclosed by the invention is applied to the central heating non-central water supply system, so that hot water can be quickly supplied and water is saved while the form and the efficiency of a heat source central heating system are kept.

Description

technical field [0001] The invention relates to a heating water supply device, in particular to a convertible water-saving electric auxiliary fast heating water supply device and a centralized heating and decentralized water supply system. Background technique [0002] The heat supply methods of the existing domestic or commercial small-scale hot water supply systems mainly include distributed heat source heating and centralized heat supply in various forms of heat sources. The current household or small-scale commercial hot water supply system mainly adopts the centralized heating method of various heat sources, and its basic structure is a centralized heating device with various thermal energy forms. The water outlet faucet is used. Distributed heat source heating adopts the method of decentralized heating and decentralized use. The distributed heat sources used mainly include electric heating and fast hot water devices such as electric heating faucets and "hot water trea...

AI Technical Summary

Problems solved by technology

[0006] Problem 1. The water faucets that are far away from the central heating device cannot realize the rapid hot water supply and use at the required temperature due to the distance of the water supply pipe containing a certain amount of cold water and the heating loss of the pipe itself, which affects psychological emotions.

For example, if the kitchen water 11, washing water 12, bathing water 14, etc., specifically as figure 2 In places such as pool 23, pool 24, bathtub 26, shower room 27, pool 28, etc., which are far away from the centralized heating device 20, the outlet water temperature may not reach the required temperature for a long time due to reasons such as ambient temperature, pipeline material and layout, etc. Causes waiting time, which can damage the user's mood

[0007] Problem 2: The water faucets that are far away from the central heating device will release a large amount of water before realizing the required temperature hot water supply due to the water supply pipe distance containing a certain amount of cold water and the heating loss of the pipe itself, which wastes both heat energy and water resources. cause great waste of resources

[0009] However, only using the existing electric heating faucet or "hot water treasure" will produce new problems three and four

[0010] Question 3. When electric heating faucets are used, the original decoration style of kitchen and bathroom products needs to be updated and changed. For example, if a brand faucet is replaced with another brand electric heating faucet, the original adjustable hot and cold water supply method needs to be changed to a single water source without cold and hot regulation formula etc.;

[0011] Question 4. If electric heating faucets or "hot water treasures" are used at all water ports, the original centralized heating system will be abandoned, investment will be wasted, and its energy-saving efficiency advantages will not be utilized
