Instant heating type drinking water heating device having filtering function

Abstract

The invention relates to an instant heating type drinking water heating device having a filtering function. The heating device includes a pipeline heater, a water pump, and a water storage tank, a detachable solid carbon cake filter element assembly is arranged on the water storage tank, the solid carbon cake filter element assembly includes a casing and a solid carbon cake filter element, the solid carbon cake filter element is arranged in the casing, the casing is provided with a water inlet and a purified water outlet, and the solid carbon cake filters the water in the casing. Such a drinking water heating device is provided with the solid carbon cake filter element (sintering filter element) assembly having the advantages of small size and good filtering and purifying effects; and moreover, the installation and detachment of the solid carbon cake filter element assembly is easy and convenient, and the small-size solid carbon cake filter element (sintering filter element) is less in use time and can prevent the defect of easy pollution due to long time use. In addition, the whole product is simple and reasonable in structure.

Description

technical field [0001] The invention relates to the technical field of instant water heating devices, in particular to an instant drinking water heating device with a filtering function. Background technique [0002] The instant drinking water heating device is a device that heats water quickly, and the user can provide the required hot water within a short waiting time. At present, the instant drinking water heating devices on the market are usually equipped with a balance water tank. The bottom of the balance water tank is provided with a water inlet and a water outlet. The water outlet is connected with the pipe heater (such as: a device that passes water through the pipe and is heated rapidly), and the bottom wall of the balance water tank is respectively provided with a high water level float switch and a low water level float switch for detecting high and low water levels; working , the water pump pumps the water source into the balance water tank, and the water is se...

Problems solved by technology

[0005] However, the filter holes of the ceramic filter are small, such as: the pore size is 0.2 microns. Although it can effectively filter out various bacteria (0.3-1.5 microns in size) and protozoa (1-100 microns in size), the processing accuracy is relatively large. The cost is high, and the manufactured ceramic filter has a large volume, which is not suitable for built-in drinking water heaters, especially drinking water heaters with water storage tanks. Traditional ceramic filters cannot be installed in the water storage tanks; moreover, if The filter is installed outside the water storage tank. Although the water entering the water storage tank h
