Abstract
The invention discloses an outlet open-type water heater with a thermal expansion drip preventing device, which consists of a liner, an outer shell, a water inlet pipe with a valve, a water outlet pipe and a heating device, and is characterized in that: a baffle plate is arranged at the upper part of the liner; an elastomer provided with a pipe and a cavity inside is arranged on the baffle plate; the pipe of the elastomer with the cavity inside passes through the liner and the outer shell to communicate the cavity of the elastomer provided with the cavity inside with the atmosphere; the water outlet pipe is a bent pipe; and an outer wall of a water inlet of the water outlet pipe is fixedly connected with the elastomer with the cavity inside. When the outlet open-type water heater of the invention is used, in a heating process of the water heater, because the thermal expansion drip preventing device is arranged, an expanded volume of heated water is smaller than the volume between an upward displacement of the pipe and the primary water level. Thus, an uncontrollable drip phenomenon does not appear; and the outlet open-type water heater improves the quality of the product and brings convenience to users.
Description
Technical field
The present invention relates to a kind of outlet open-type water heater, particularly relate to the outlet open-type water heater that a kind of anti-water heater thermal expansion is dripped.
Background technology
Outlet open-type water heater and closed water heater's ratio have the water heater wall and need not to bear advantages such as fatigue of materials that the closed water heater bears produces because of the pressure frequent variations, stress corrosion, still; The ubiquitous problem of outlet open-type water heater, that is exactly that water at outlet open-type water heater is heated in the process water expanded by heating; Thereby the volume of water is increased, water will overflow from outlet pipe, dripping phenomenon occurs; Both wasted water; Waste energy again, also cause and remove troubles such as water stain, limited should technology use.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of outlet open-type water heater that has thermal expansion drip preventing device is provided.
Technical scheme of the present invention is summarized as follows:
A kind of outlet open-type water heater that has thermal expansion drip preventing device; Form by inner bag, shell, the water inlet pipe that has valve, outlet pipe and heater; Top at said inner bag is provided with baffle plate; Said baffle plate is provided with the elastomer that there is cavity the inside that has pipe; Said inside has the elastomeric pipe of cavity to pass said inner bag and shell makes said inside that the elastomeric inner chamber and the atmosphere of cavity arranged, and said outlet pipe is a bend pipe, and the outer wall of the water inlet of said outlet pipe has the elastomer of cavity to be fixedly connected with said inside.
There is elastomeric spherosome or the spheroid or the cube of being shaped as of cavity said inside, and the elastomer that has inner chamber of other shapes is all passable.
Advantage of the present invention is:
The present invention in use, in water heater heating process, because the setting of thermal expansion drip preventing device is arranged; After water is heated; The volume ratio pipe that the is expanded volume that forms between displacement and the initial condition liquid level that raises up is little, and this is characteristics of the present invention, uncontrollable dripping phenomenon can not occur; Improved the quality of product, for users provide convenience.
Description of drawings
Fig. 1 is a kind of structural representation that has the outlet open-type water heater of thermal expansion drip preventing device of the present invention;
Fig. 2 is a kind of working state schematic representation that has the outlet open-type water heater of thermal expansion drip preventing device;
Fig. 3 is arranged on the structural representation at water heater top for a kind of outlet pipe that has the outlet open-type water heater of thermal expansion drip preventing device.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
A kind of outlet open-type water heater that has thermal expansion drip preventing device; Form by inner bag 1, shell 2, the water inlet pipe 3 that has valve, outlet pipe 4 and heater 5; Be provided with baffle plate 12 on the top of inner bag; Baffle plate is provided with the elastomer 13 that there is cavity the inside that has pipe; Inside has the elastomeric pipe of cavity to pass inner bag and shell makes inside that the elastomeric inner chamber and the atmosphere of cavity arranged, and outlet pipe is a bend pipe, and the outer wall of the water inlet of outlet pipe has the elastomer of cavity to be fixedly connected with inner.
There is elastomeric spherosome or the spheroid or the cube of being shaped as of cavity said inside, and the elastomer that has inner chamber of other shapes is all passable.
A kind of outlet open-type water heater that has a thermal expansion drip preventing device in use; After water was heated, because one section expanding volume is arranged, pipe exported in gas phase; Can top gas be discharged during heating; Can not have the elastomer of cavity to shrivel inside, the thermal expansion of the water that the time causes in heating makes the position of moving on the hot water liquid level be lower than the position of the outlet pipe mouth of pipe, so hot water is not understood outer dripping.Because the hydraulic pressure conference has inside the gas in the elastomer of cavity to extrude, there is the elastomer of cavity to be flattened during water inlet, causes the outlet pipe mouth of pipe to be positioned under the liquid level; Can use hot water; After using hot water to finish, stopping into water, tends to balance gradually in the water heater internal pressure and the external world; There is the elastomer of cavity to restore to the original state, the mouth of pipe of outlet pipe is raised up.This is for the top of outlet pipe opening at water heater, or is the same in the bottom of water heater.
Claims (2)
1. outlet open-type water heater that has thermal expansion drip preventing device; Form by inner bag, shell, the water inlet pipe that has valve, outlet pipe and heater; It is characterized in that being provided with baffle plate on the top of said inner bag; Said baffle plate is provided with the elastomer that there is cavity the inside that has pipe; Said inside has the elastomeric pipe of cavity to pass said inner bag and shell makes said inside that the elastomeric inner chamber and the atmosphere of cavity arranged, and said outlet pipe is a bend pipe, and the outer wall of the water inlet of said outlet pipe has the elastomer of cavity to be fixedly connected with said inside.
2. a kind of outlet open-type water heater that has thermal expansion drip preventing device according to claim 1 is characterized in that there is elastomeric spherosome or the spheroid or the cube of being shaped as of cavity said inside.
