Embodiment 1

[0040] Such as Figure 3 to Figure 7As shown, this embodiment introduces an inlet water filter device 100 for a water heater, which includes a housing 1 provided with a water inlet 2 and a water outlet 3; The primary filter screen 6 for removing particulate impurities, the primary filter screen 6 divides the inside of the shell 1 into two parts, the inside and the outside; the water inlet 2 of the shell 1 is connected to the part between the primary filter screen 6 and the shell 1, and the primary filter screen 6 is equipped with a filter element 8 for removing impurities such as fine particles, bacteria, and heavy metals contained in the incoming water. 3 water ports are connected. Thus, the incoming water flows through the primary filter screen 6 and the filter element 8 in sequence to remove large particles such as silt and fine particle impurities such as bacteria and heavy metals in the incoming water, so as to achieve the purpose of comprehensively filtering the incomin...

Embodiment 2

[0053] Such as Figure 3 to Figure 7 As shown, this embodiment introduces a water inlet filter device for a water heater. The shell 1 of the water inlet filter device 100 is composed of a hollow columnar structure, one end is closed and the other end is provided with a detachable rear end cover 5 . The closed end of the casing 1 is provided with a water inlet 2 and a water outlet 3 . The casing 1 is provided with a coaxial primary filter screen 6 with a cylindrical side wall surrounding the city. The primary filter screen 6 divides the interior of the casing 1 into two parts, the inner and outer parts, which are independent of each other. The water inlet 2 and the primary filter screen 6 and the casing The parts between 1 are connected, so that the incoming water flows through the primary filter screen 6 to remove large particles of impurities such as contained silt. The primary filter screen 6 is provided with a coaxially arranged, cylindrical filter element 8, the end of th...

Embodiment 3

[0062] Such as Figure 8 to Figure 10 As shown, the present embodiment introduces a kind of inlet water filtering device 100 for a water heater, which includes a first housing 11 and a second housing 12 respectively constituting independent chambers; The removed primary filter screen 6; the second housing 12 is provided with a filter element 8 for fine particles, bacteria, and heavy metals contained in the incoming water. The insides of the first housing 11 and the second housing 12 are communicated through a connecting pipeline 10 . Thus, the incoming water passes through the primary filter screen 6 in the first casing 11 to remove large particles of impurities such as silt and colloid, and passes through the filter element 8 in the second casing 12 to remove fine particles such as residual chlorine, heavy metals, and bacteria. Impurities, so that the filter device is equipped with a primary filter screen 6 and a filter element 8 at the same time or separately according to t...

Abstract

The invention relates to a self-cleaning inlet water filtering apparatus of a water heater. The self-cleaning inlet water filtering apparatus includes a housing provided with a water inlet and a water outlet, wherein the housing is internally provided with a primary filter screen dividing the inside of the housing into an internal part and an external part which are independent. The water inlet communicates with a part formed between the primary screen and the housing, and the water outlet communicates with the inside of the primary filter screen. The housing is further provided with a sewage draining port communicating the part formed between the primary screen and the housing with the outside, and the inlet water is utilized to flushing off silt blocked by the primary filter screen. Through the apparatus, self-cleaning of the inlet water filtering apparatus is achieved. The invention further relates to a water heater, and an inlet pipe of the water heater is provided with the self-cleaning inlet water filtering apparatus. The self-cleaning inlet water filtering apparatus is simple in structure, obvious in effect and suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a self-cleaning water inlet filter device for a water heater. Background technique [0002] After the existing water heater with filtering function is used for a period of time, with the prolongation of the use time of the filter device, a large amount of impurities such as sediment and other large particles trapped by the filter screen will accumulate in the filter device, resulting in a decrease in the permeability of the filter screen. affect the water flow rate. Moreover, it is inconvenient for the user to disassemble and assemble the filter screen and other components in the filter device during use, resulting in that the filter screen and other components cannot be cleaned and replaced in a timely and convenient manner. [0003] At the same time, with the improvement of living standards, consumers' requirements for bathing have also increased. Only fast, energy-saving bathing...
