Problems solved by technology

Therefore, in addition to the water inlet and outlet, the liner of the existing water storage type electric water heater is generally also provided with a sewage outlet, and a sewage valve is installed on the sewage outlet for the user to perform sewage treatment on the water heater liner. However, the water heater liner does not have The transparent window, the user cannot observe the scale deposition, does not know the cleanliness of the water body in the inner tank of the water heater, often delays the best time for sewage discharge, causes more and more dirt deposits in the inner tank, easily corrodes the inner tank, and shortens the life of the water heater

Embodiment 1

[0022] like Figure 1-2 As shown, a self-cleaning visible sewage discharge device for an electric water heater is installed on the sewage outlet of the water heater, and includes a joint 2, a transparent window seat, and a switch assembly. The inner cavity of the window seat is connected, and the switch assembly can make the inner cavity of the transparent window seat and the outside world be in a closed or conducting state. The transparent window seat includes a support 8 and a transparent sleeve 3, and the transparent sleeve is sealed and sleeved outside the support to form a transparent inner cavity. The switch assembly includes a valve switch 5 and a ceramic spool 4, valve holes are arranged on the valve switch and the ceramic spool, and ceramic spools are symmetrically arranged on both sides of the valve switch. The valve switch includes a body and a wrench. The ceramic valve core is sealed in the inner cavity of the support with a sealing ring 9. The wrench of the valve...

Embodiment 2

[0026] like image 3 As shown, a self-cleaning visible sewage discharge device for an electric water heater is installed on the sewage outlet of the water heater, and includes a joint 2, a transparent window seat, and a switch assembly. The inner cavity of the window seat is connected, and the switch assembly can make the inner cavity of the transparent window seat and the outside world be in a closed or conducting state. The transparent window seat includes a first support 11, a transparent cover 3, and a second support 12. Both ends of the transparent cover are respectively connected to the first and second supports, and a switch assembly is arranged in the first and second supports. The switch assembly includes a valve switch 5 and a ceramic spool 4, valve holes are arranged on the valve switch and the ceramic spool, and ceramic spools are symmetrically arranged on both sides of the valve switch. The valve switch includes a body and a wrench set. The ceramic valve core 4 i...

Abstract

The invention discloses a self-cleaning electric water heater visual drainage device which is installed on a water heater drainage port. The self-cleaning electric water heater visual drainage device comprises a joint, a transparent window seat and a switch assembly, wherein the water heater drainage port is connected with the transparent window seat through the joint, so that the liner of the water heater communicates with the inner cavity of the transparent window seat; by using the switch assembly, the inner cavity of the transparent window seat can be in the closed or communicating state with the outside; a window impeller is arranged in the inner cavity of the transparent window seat; the edge of the window impeller is provided with a wiping unit which is used for wiping the inner wall of the transparent window seat; and a long grip of the window impeller is connected with the switch assembly. The water quality in the liner of the electric water heater can be directly monitored in time through the transparent window; the transparent window can be kept clean and clear for a long time; and thus, the drainage device is reasonable in structure, safe and convenient to use and quick in drainage, prolongs the service life of the electric water heater, and enhances the market competitiveness of the product.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a self-cleaning visible sewage discharge device for electric water heaters. Background technique [0002] Due to the differences in water quality in various places, the tap water also contains impurities such as sediment and rust. In addition, the storage-type electric water heater will inevitably form scale when heated during use. Dirt will be deposited on the bottom of the liner. Therefore, in addition to the water inlet and outlet, the liner of the existing water storage type electric water heater is generally also provided with a sewage outlet, and a sewage valve is installed on the sewage outlet for the user to perform sewage treatment on the water heater liner. However, the water heater liner does not have The transparent window, the user cannot observe the scale deposition, does not know the cleanliness of the water body in the inner tank of the water heater, often ...
