A kind of water heater heating core
Technical field
The present invention relates to technical field of water heaters, more particularly, to a kind of water heater heating core.
Background technology
All containing this core parts of heating core, the quality of heating core directly affects water heater to electric heating hot water
Using effect.Heating core of the prior art is being arranged on heating core housing of many heating tube simple superposition, its heating speed
Degree is slow, and efficiency is low, and the attachment structure between heating tube and heating core housing is unstable, after long-time use, is easily caused
Whole heating core deformation, directly affects its sealing and service life.
Content of the invention
The present invention is mainly the technical problem in the presence of solution prior art, thus providing a kind of firing rate fast, close
Good, the constitutionally stable water heater heating core of envelope property.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
The water heater heating core that the present invention provides, including upper shell and lower house, close between described upper shell and lower house
Envelope has multiple heating tubes, is provided with a water inlet in described upper casing body, is provided with an outlet in described lower casing body, described upper shell and
It is equipped with multiple interface channels, described interface channel is used for connecting multiple described heating tubes, and multiple described inside lower house
It is additionally provided with external seal gripping mechanism, described external seal gripping mechanism is used for sealing fixing described heating tube, described between heating tube
External seal gripping mechanism includes the sealing card of integrated molding, and described sealing card includes fit portion and tight lock part, described fit portion
It is set in the outside of described heating tube, described tight lock part is locked by bolt.
Further, be further fixed on multiple support bars between described upper shell and lower house, the position of described tight lock part with
The position of described support bar is corresponding.
Further, described support bar and the connected mode of described upper shell and lower house are detachable.
The beneficial effects of the present invention is:Connect heating tube by arranging multiple interface channels in upper and lower shell body, make heat
Water in hydrophone, in flow process, obtains heating for multiple times, and the efficiency of heating surface is high, and speed is fast, and by arranging external seal clamping
Device, not only makes the attachment structure between heating tube more firm, and plays certain sealing function, increased heating core
Service life.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, acceptable
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the water heater heating core of the present invention;
Fig. 2 is the sectional view along line A-A for the Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clearly defining.
Refering to shown in Fig. 1-2, the water heater heating core of the present invention, including upper shell 1 and lower house 2, upper shell 1 and lower casing
It is sealed with multiple heating tubes 3 between body 2, in upper shell 1, is provided with a water inlet 4, in lower house 2, be provided with an outlet 5, upper shell
1 and lower house 2 inside be equipped with multiple interface channels 6, interface channel 6 is used for connecting multiple heating tubes 3, and multiple heating tube
It is additionally provided with external seal gripping mechanism, external seal gripping mechanism is used for sealing fixing heating tube 3 between 3.The present invention passes through upper and lower
In housing, the multiple interface channel 6 of setting connects heating tube 3, makes the water in water heater in flow process, obtains heating for multiple times, plus
The thermal efficiency is high, and speed is fast, and by arranging external seal gripping mechanism, not only makes the attachment structure between heating tube 3 more steady
Gu, and play certain sealing function, increased the service life of heating core.
Specifically, external seal gripping mechanism includes the sealing card 7 of integrated molding, and sealing card 7 includes fit portion 71 and lock
Tight portion 72, fit portion 71 is set in the outside of heating tube 3, and the material in fit portion 71 is soft rubber, and tight lock part 72 passes through bolt
73 are locked.It is further fixed on multiple support bars 8, support bar 8 is used for supporting whole adding between upper shell 1 and lower house 2
The structure of hot core, preferably, the position of tight lock part 72 is corresponding with the position of support bar 8, in fastening locking, bolt 73 is located at
The both sides of support bar 8, increased the stability of structure.And, for the ease of dismantling and keeping in repair, support bar 8 and upper shell 1 and under
The connected mode of housing 2 is detachable.
More than, the specific embodiment of the only present invention, but protection scope of the present invention is not limited thereto, any without
Cross the change or replacement that creative work is expected, all should be included within the scope of the present invention.Therefore, the protection of the present invention
Scope should be defined by the protection domain that claims are limited.
