Abstract

The invention discloses a water heater. The water heater comprises an inner container, a water inlet pipe, a water outlet pipe and a filter device arranged in the inner container. The water heater is characterized in that the filter device comprises an outer layer, an inner layer and a filter medium; the filter medium is contained in an interlayer cavity formed by the outer layer and the inner layer; at least part of the outer layer and / or the inner layer is a region allowing the water flow to pass; and the filter device is located in the inner container. By the adoption of the structure, the filtering performance of the water heater can be improved, the contact time of the water flow in the filter medium is prolonged as much as possible, the contact area of the water flow in the filter medium can be increased as much as possible, the pressure required by filtering is lowered, and the filtering rate is increased.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a water heater. Background technique [0002] The existing water heater includes a water tank with an inner tank, a water inlet pipe and a water outlet pipe arranged on the water tank, and a heat exchange device for exchanging heat with the water in the water tank. During the working process, some impurities (such as large particles, dirt, etc.) are often accumulated in the inner tank of the water heater. Filtration devices are often provided on water heaters to physically or chemically react with certain elements or substances or impurities in the water, thereby removing impurities (such as heavy metals, etc.) in the inner tank. [0003] However, it has been proved by practice that the filtering efficiency of the filtering devices in the prior art is not good. Thereby it is necessary to provide a water heater with better filtering function. Contents of the inve...
