Embodiment 1

[0035] This embodiment is an embodiment of the basic structure of the present invention, which can realize the judgment of the use of the filter element and realize cleaning, but the cleaning process requires manual control of the valve, and the degree of automation is not high.

[0036] Such as figure 1 , a water heater with the function of reminding and cleaning the filter element, comprising a water heater body 1, a controller 9 is arranged on the water heater body 1, a filter element 3 is arranged on the water inlet pipe 2 of the water heater body 1, and the water inlet pipe is located between the water inlet of the filter element. The side is the water inlet section 21, and the side of the water outlet of the filter element is the water outlet section 22. The water inlet section 21 is provided with a water inlet section pressure sensor 41 and a water inlet section flow sensor 51 connected to the controller 9. The water outlet section The section is provided with a water o...

Embodiment 2

[0047] This embodiment is an optimization based on the first embodiment, and the pipeline layout and valve positions are evenly changed, but the three-way valve and the sewage valve are electric valves and connected to the controller, and the controller adds a cleaning module, etc. It can realize the automatic completion of detection and cleaning.

[0048] Such as figure 2 , since the pipeline structure and valve position are the same as those in Embodiment 1, the same parts will not be repeated here. It only describes the connection relationship between the three-way valve 71 of the water inlet section, the three-way valve 72 of the water outlet section and the drain valve 81 and the controller 9 , and the module structure of the controller 9 .

[0049] specific as Figure 4 , the controller 9 includes a reminder module 92 and a cleaning module 93 connected to the CPU91. The three-way valve 71 of the water inlet section, the three-way valve 72 of the water outlet section ...

Embodiment 3

[0053] This embodiment is a further optimization of embodiment two, such as image 3 , this embodiment is to change the pipeline arrangement of the second embodiment, shortening the length occupied by the filter element under the water heater. It is conducive to installation, reduces the occupation of toilet space, and is convenient for users to use. This embodiment is a preferred embodiment of the present invention.

Abstract

The present invention discloses a water heater having an automatic filtration core washing function, and a control method thereof. The water heater comprises a water heater body, a controller and a water inlet pipe, wherein the water inlet pipe is provided with a filtration core, the water inlet pipe side at the water inlet of the filtration core is a water inlet section, the water inlet pipe side at the water outlet of the filtration core is a water outlet section, the water inlet section and the water outlet section are respectively provided with a pressure sensor and a flow rate sensor connected to the controller, a backwash pipe is arranged between the water inlet section and the water outlet section, both ends of the backwash pipe are communicated to the water inlet section and the water outlet section respectively through a water inlet section three-way valve and a water outlet section three-way valve, the filtration core is provided with a sewage discharging port or a sewage discharging port is arranged between the water inlet section three-way valve and the filtration core, and the sewage discharging port is provided with a sewage discharging valve. According to the present invention, with the water heater, the disadvantage that the filtration core of the existing water heater cannot be automatically washed is overcome, the washing can be performed by automatically judging the filtration core use condition, and the filtration replacement reminder can be emitted when the filtration core cannot be effectively washed, such that the water purification effect is improved while the service life of the filtration core is prolonged.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater with the function of automatic cleaning of filter elements and a control method. Background technique [0002] Water storage type electric water heater, because the water quality contains sediment, impurities, etc. will affect the service life of the water heater and endanger the health of users. In order to purify the water quality, a filter element is generally added to filter at the front end of the water inlet of the water heater. However, after the filter element has been filtered for a period of time, a large amount of suspended particles and impurities will accumulate, resulting in a decline in the purification effect. If the accumulated impurities stay on the surface of the filter element for a long time, it will not be easy to clean, and it is also easy to breed bacteria, which will affect the water quality and the health of users. Moreover, too many impurit...
