Household intelligent central hot-water system

Abstract

The invention discloses a household intelligent central hot-water system, comprising a rapid heating device and a water storage device, wherein a water inlet joint at the bottom of the water storage device is communicated with the water inlet end of the rapid heating device through an inner circulating cold water pipe; an inner circulating pump is arranged on the inner circulating cold water pipe; the water outlet end of the rapid heating device is communicated with the upper part of the water storage device through an inner circulating hot water pipe; the top end of the water storage device is provided with a water outlet joint communicated with a water outlet pipe; a water inlet pipe communicated with the water inlet joint is provided with an inlet water flow sensor; the water outlet pipe is provided with an outlet water temperature detector; and the inner circulating cold water pipe is provided with an inner circulating water flow sensor. In the household intelligent central hot-water system, the advantages of a rapid gas water heater and the advantage of a positive-displacement gas water heater are organically combined, so that the household intelligent central hot-water system has the advantages that hot water can be rapidly and continuously supplied for a long time and is not influenced by external factors, water is discharged at the constant temperature, hot water is discharged with no need of waiting, and the like.

Description

technical field [0001] The invention relates to a central hot water system, in particular to a household intelligent central hot water system which organically combines a fast type and a volumetric type. Background technique [0002] Gas water heaters currently on the market can be divided into two categories: instant gas water heaters and volumetric gas water heaters according to their structure. [0003] Among them, the rapid gas water heater is also called the flow water heater, which can supply hot water quickly and continuously for a long time. It is small in size and very convenient to use immediately. The stove has high thermal efficiency (not less than 55%) and short heating time (not more than 45 seconds), which has been widely popular among customers. However, because the instant gas water heater itself has no storage volume, there is a period of cold water before hot water is produced. When in use, the waiting time for hot water is long, requiring a certain start...

AI Technical Summary

Problems solved by technology

However, the volumetric gas water heater cannot be used for a long time with a large flow due to its limited water storage capacity, and after the water in the bucket is used up, the waiting time for re-use is long

[0005] In response to the above problems, the applicant applied for a Chinese utility model patent "A Variable Type Gas Water Heater" (Patent No. 200720080101.X) on June 27, 2007. Combined, but due to the lack of structural design, it did not achieve the desired effect. On the contrary, the temperature fluctuated greatly, the starting water pressure was high, and there was still a problem of waiting time when using it.
