Problems solved by technology

[0004] At the same time, after the existing water heater with filtering function has been used for a period of time, with the prolongation of the use time of the filter device, a large amount of large particles such as silt and other impurities trapped by the filter screen will accumulate in the filter device, resulting in the passability of the filter screen. Decrease, 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.

Embodiment 1

[0037] Such as Figure 1 to Figure 7 As 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 incomi...

Embodiment 2

[0042] Such as Figure 2 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

[0051] This embodiment introduces a water inlet filter device for a water heater, which includes a casing 1, which is provided with a primary filter screen 6 that divides the inside of the casing 1 into two independent parts, the inside and the outside; the water inlet 2 of the filter device is connected to the primary The filter screen 6 is connected to the shell 1, and the water outlet 3 is connected to the inside of the first-stage filter screen 6, so that the incoming water flows into the shell 1 through the water inlet 2 and the sediment in the water is removed by the first-stage filter screen 6. Such impurities are filtered and retained between the primary filter screen 6 and the shell 1 to achieve the purpose of filtering large particles such as sediment in the influent.

[0052] As the filter device is used for a longer period of time, large particles of impurities such as silt and sand retained by the primary filter screen 6 may accumulate in large quantities, resultin...

Abstract

The invention relates to an inlet water filtering apparatus of a water heater. The inlet water filtering apparatus comprises a housing, which is internally provided with a primary filter screen for removing silt from inlet water. The primary filter screen divides the inside of the housing into an internal part and an external part which communicate with a water inlet and a water outlet, respectively. The primary filter screen is internally provided with a filtering core for removing fine particles, bacteria and heavy metal from the inlet water. Through the apparatus, large particle impurities including silt and colloid and fine particle impurities including residual chlorine, heavy metal and bacteria can be removed from inlet water. The apparatus has the effect of removing dirt, killing bacteria and inhibiting scale. The invention further relates to a water heater with the inlet water filtering apparatus installed. Inlet water of the water heater can be fully filtered, thereby improving the bathing comfort degree and prolonging the service life of the water heater. At the same time, the 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 water inlet filter device for the water heater. Background technique [0002] With the improvement of living standards, consumers' requirements for bathing have also increased. Only fast, energy-saving bathing methods can no longer meet the needs of users. Health is an important indicator that people generally pay attention to. At present, most of the storage water heaters on the market work in the way that tap water from the user’s home is connected to the water heater inlet. After heating, the cold and hot water are mixed and then flow out from the outlet of the mixing valve. The whole process does not improve the tap water quality. The long-term accumulation of sediment, residual chlorine, heavy metals, bacteria, etc. in the tap water pipes will have a negative impact on bathing, and at the same time bring hidden dangers to the life of the water heater. [0003] Therefore, du...
