Abstract
A rapid water heater with a waterproof structure comprises a casing and a heating body arranged in the casing. A water sealing part is arranged between the casing and the heating body, the heating body is provided with a joint portion, the joint portion includes a water inlet joint and a water outlet joint, at least a first water retaining wall and a second water retaining wall are arranged on one side of the water sealing part and surround the joint portion from outside to inside, a first water chute is formed outside the first water retaining wall, a second water chute is formed between the second water retaining wall and the first water retaining wall, height difference is arranged between the first water chute and the second water chute, a first drainage opening for leading water to flow from the second water chute into the first water chute is arranged on the first water retaining wall, and a joint portion is positioned inside the first water chute. Compared with the prior art, the rapid water heater with a waterproof structure has the advantages that water entering a gap of the water sealing part is blocked by the first water retaining wall and the second water retaining wall prior to automatically flowing from the second water chute into the first water chute due to the height difference, and finally is drained out of the casing in a dredged manner without infiltration layer by layer, thereby improving water sealing effect.
Description
Technical field
The utility model relates to a kind of water heater, relates in particular to a kind of instantaneous water heater with waterproof construction.
Background technology
Existing instantaneous water heater, comprise housing substantially and be located at the interior heater body of housing, heater body has connector portions, this connector portions comprises admitting pipe joint and titting water outlet, the automatically controlled part that enters between heater body and the housing for anti-sealing causes short circuit, generally between housing and heater body, be provided with watertight seal, though common watertight seal can satisfy seal request under certain condition, but there is difficult operational issue on realizing, and after using a period of time, the waterproof ability of seal can reduce greatly along with aging and distortion, cause outside water can flow into or be splashed into the automatically controlled part of machine intimate easily, cause the internal wiring fault or cause security incident.
In addition, because of case temperature much smaller than heater body, both cooperate the local deformation that must cause housing down, cause the slit between housing and the heater body to produce inhomogeneous and irregularities, even use the better seal part also can't thoroughly fill up these slits, be difficult to guarantee waterproof effect, particularly under strong hydraulic pressure sprays, water can progress in the gap of seal and housing, and then can not pass through waterproof requirement.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of water seal the good instantaneous water heater with waterproof construction at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of instantaneous water heater with novel water guide structure, comprise housing and be located at the interior heater body of housing, be provided with watertight seal between housing and the heater body, heater body has connector portions, this connector portions comprises water supply connector and water out adapter, it is characterized in that described watertight seal one gusset solderless wrapped connection head is from having first waterwall and second waterwall outside to inside at least, this first waterwall outside is formed with first guiding gutter, and be formed with second guiding gutter that difference in height is arranged with aforementioned first guiding gutter between second waterwall and first waterwall, this first waterwall offers water is flowed into first discharge outlet of first guiding gutter from second guiding gutter, and described connector portions then is positioned at aforesaid first guiding gutter.
Further, to improve the water seal effect, at least also has the 3rd waterwall of being located in second waterwall on the described watertight seal, be formed with the 3rd guiding gutter that difference in height is arranged with second guiding gutter between the 3rd waterwall and second waterwall, and described second waterwall offers second discharge outlet that water is flowed into second guiding gutter from the 3rd guiding gutter.
Described second discharge outlet and the first discharge outlet bit interleave are arranged.Improve the efficient of dredging of current, simultaneously, the water that the water that can further prevent first guiding gutter enters second guiding gutter and second guiding gutter enters the 3rd guiding gutter.
Further, described the 3rd guiding gutter takes shape at least one side of connector portions, and described second discharge outlet and first discharge outlet also all take shape at least one side of connector portions.
As improvement, described housing bottom is provided with and is used to accept the apopore that flows out water from first guiding gutter.
Compared with prior art, advantage of the present utility model is: the water that enters in the watertight seal gap is subjected to first waterwall and second waterwall to stop that the back flows to first guiding gutter because of difference in height automatically from second guiding gutter, discharge housing by the mode of dredging at last, can not cause layer by layer and infiltrate, improve the water seal effect, reduced potential safety hazard.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, instantaneous water heater in the present embodiment comprises fore shell 11, bonnet 12 and heater body 2, fore shell 11 and bonnet 12 are formed housing 1, heater body 2 is located in the housing 1, be provided with watertight seal 3 between housing 1 and the heater body 2, heater body 2 has connector portions, and this connector portions comprises water supply connector 21 and water out adapter 22.
Have the 4th waterwall 44, the 3rd waterwall 43, second waterwall 42, first waterwall 41 on watertight seal 3 end faces one side from inside to outside, outer waterwall 4a, be formed with the 4th guiding gutter 34, the 3rd guiding gutter 33, second guiding gutter 32 and first guiding gutter 31 between them respectively, and descend highly step by step, be formed with the 3rd discharge outlet 53 on the 3rd waterwall 43, be formed with second discharge outlet 52 on second waterwall 42, be formed with first discharge outlet 51 on first waterwall 41, be formed with outer discharge outlet 5a on the outer waterwall 4a.
Wherein, joint area is in first guiding gutter 31, second guiding gutter 32 is around the connector portions setting, promptly first waterwall 41 and second waterwall 42 are around the connector portions setting, the 3rd guiding gutter 33 and the 4th guiding gutter 34 all take shape in the connector portions both sides, and the 3rd discharge outlet 53 second discharge outlet 52 and first discharge outlet 51 also all take shape in the connector portions both sides.
As shown in Figure 2, if there is water to leak from water supply connector 11 or water out adapter 12, under the stopping of first waterwall 41 and second waterwall 42, water can be pooled to first guiding gutter 31, discharge from outer discharge outlet 5a at last, discharge outside the water heater through the apopore 13 of housing.The arrow indication is the flowing water flow direction.
