Referring to FIG. 3, in one particular embodiment, the intake filter assembly 220 further comprises: a filter element 220 c;

the cartridge 220c is detachably coupled between the general water inlet 220a and the general water outlet 210 a.

The utility model discloses hanging stove with drainage function, filter assembly 220 that intakes includes filter core 220c, and water gets into and filters the back through filter core 220c from total water inlet 220a, exports the cold water inlet to the total delivery port 210a of first casing 210 and enters into plate heat exchanger again. When the filter element 220c needs to be cleaned, the water inlet filter assembly 220 arranged in the first shell 210 is detached, so that the operation is simple and convenient.

Referring to fig. 3 and 4, in one particular embodiment, cartridge 220c includes: a first filter structure 222 and a second filter structure 224; the first filtering structure 222 includes a flow guide part 222b and a water filtering part 222 a.

The water filtering part 222a is provided with a filter element water outlet 2201 communicated with the main water outlet 210 a; the diversion portion 222b is provided with a plurality of diversion water outlets 2202 and a cartridge water inlet 2203 communicating with the main water inlet 220 a.

A flow passage communicated with the water filtering portion 222a and the split water outlet 2202 is formed between the inner wall of the first housing 210 and the first filtering structure 222; the second filtering structure 224 is located in the flow passage and disposed between the water filtering portion 222a and the divided water outlet 2202.

The opening side of the diversion water outlet 2202 is biased toward the direction of gravity.

For example, the opening side of the diverting outlet 2202 is flush with the surface of the flow guiding portion 222b, or protrudes downward from the surface of the flow guiding portion 222b in the vertical direction, so that the opening side of the diverting outlet 2202 faces the direction of the deviating gravity, and impurities in the water flow can be prevented from flowing back into the flow guiding portion 222b from the diverting outlet 2202 under the action of the gravity.

The first filter structure 222 and the second filter structure 224 of the filter element 220c may be integrally formed or may be separate components that are butted against each other. The first filtering structure 222 including the flow guiding portion 222b and the water filtering portion 222a may be a cylindrical member, one end of which is the flow guiding portion 220b, and the other end of which is the water filtering portion 222 a. For example, a flow guide baffle, preferably an inverted cone-shaped "V" flow guide baffle, may be disposed in the flow guide portion 222b and at the diversion outlet 2202 to form a flow guide surface, so as to reduce the resistance to water, so as to enable the water to flow out of the diversion outlet 2202 more smoothly. For example, when water flow (as shown by the arrow in fig. 4) enters the main water inlet 220a, it flows out of the divided water outlet 2202 of the flow guide portion 222b into the runner passage. Because the second filtering structure 224 is located between the water filtering portion 222a of the first filtering structure 222 and the diversion water outlet 2202, and is located in the flow channel, the water flow can flow out after being filtered by the second filtering structure 224, and the water flow needs to change the direction of the water flow and enters the water filtering portion 222a from the flow channel, at this time, the water flow speed is slowed down, and it is more favorable for blocking impurities in the water flow outside the water filtering portion 222a again, and then the water flow flows out through the filter element water outlet 2201 of the water filtering portion 222a and the main water outlet 210 a.

The utility model discloses hanging stove with drainage function, because second filtration 224 is located the runner, and sets up at drainage portion 222a and divides between the outlet 2202, and the opening side orientation of dividing the outlet 2202 is partial to the gravity direction. Under the action of the flow guiding portion 222b, the water flow passes through the second filtering structure 224 in the flow channel and then enters the water filtering portion 222a, the flow rate of the water flow is slowed down, impurities in the water flow are filtered in the flow channel on one side of the second filtering structure 224 in advance, the cleanliness of the flow channel on the other side of the second filtering structure 224 is further improved, and meanwhile, other impurities can be filtered out of the water filtering portion 222a of the first filtering structure 222. The utility model discloses effectively optimized filter equipment's filter effect, and its structure is comparatively simple easily to be realized, and the cost is lower, is convenient for use in most hanging stove. Meanwhile, after the water inlet filter assembly 220 is separated from the first shell 210 in the later maintenance, the filter element 220c is quickly disassembled and cleaned, and the assembly is convenient.

Referring to fig. 1, in one embodiment, the second filter structure 2224 is sleeved on the first filter structure 222, and the first filter structure 222 and the second filter structure 2224 are at a predetermined angle; the predetermined angle range is [80 °, 100 ° ].

For example, the predetermined angle may be, for example, 85 ° or 95 °, preferably 90 °, i.e., the first filter structure 222 and the second filter structure 224 may be perpendicular to each other. The predetermined angle range is reasonably moderate, so that the structural installation between the first filter structure 222 and the second filter structure 224 is stable and firm.

Referring to fig. 5 and 6, in a particular embodiment, the water filtering device 20 further comprises: a check valve 230, a packing 240, and an elastic member 250.

A sewage channel 2204 communicated with the flow channel is arranged on the second shell 220 b; the one-way valve 230 is movably disposed in the trapway 2204; the sealing ring 240 is sleeved at one end of the check valve 230; a resilient member 250 is disposed in the trapway 2204 between the outer wall of the one-way valve 230 and the inner wall of the second housing 220b to urge the one-way valve 230 and the sealing ring 240 to seal the trapway 2204.

For example, during draining, the one-way valve 230 may be pushed towards the inside of the wall-mounted furnace housing, at this time, one end of the elastic member 250 abuts against the drain port on the drain passage 2204 near the split-flow water outlet 2202, and at the same time, the elastic member is in a compressed state under the reaction force of the drain port and the one-way valve 230, and the sealing ring 240 is separated from the drain passage, at this time, the water filtering device is in a drain state (as shown in fig. 6). When the sewage draining is not needed, the one-way valve 230 is driven by the elastic force of the elastic component 250 to move towards the outside of the housing, so that the sewage draining channel 2204 is sealed by the sealing ring 240 (as shown in fig. 5) during the moving process.

The utility model discloses hanging stove with drainage function, the structure is comparatively perfect and easily realize, and accessible elastomeric element 250, sealing washer 240 and check valve 230 mutually support, reach self-sealing sewage pipes 2204's effect, and its easy operation is convenient. Simultaneously, be convenient for with impurity 300 filtering fast, and then when satisfying hanging stove drainage demand, still can improve the convenience of using.

Referring to fig. 7, in a specific embodiment, the water filtering part 222a includes: a first filter screen 2206 and a filter support 2208 provided with a filter element water outlet 2201; the first filter 2206 is disposed on the filter support 2208 and is in communication with the flow passage.
