Abstract
A liquid heater comprises a shell and a pipe type heating body provided with an inner cavity used for heating liquid, two ends of the pipe type heating body are respectively a liquid inlet and a liquid outlet, a water switch is installed at the position of the liquid inlet, and a decompression valve and a temperature control device are installed at the position of the liquid outlet. The liquid heater is a secondary heating device aiming to overcome the defects that hot water is insufficient in a using process of a solar water heater and a storage water heater, and the liquid heater enables users to feel more comfortable and achieves long-time supply of the hot water. In addition, the liquid heater integrates functions of water pressure starting, overpressure protection and overtemperature protection, so that the liquid heater can serve as an independent electrical appliance to be used, for example, the liquid heater can be installed between a faucet and a pipe or between a sprinkler and the pipe to achieve the purpose of warm water supply.
Description
Technical field
The utility model relates to a kind of liquid heater, a kind of Instant heating type liquid heater that is used on the taps such as bathroom, kitchen particularly, and liquid heater also is a kind of for solar water heater, the storage-type electric water heater second heating device developed of hot water deficiency in use.
Background technology
Existing water heater generally is divided into instant electric water heater, storage-type electric water heater, solar water heater and gas heater, wherein, because instant electric water heater's power high (generally more than 3KW) is very big to the load of home circuit, use so fail to popularize; And along with blowing rise the price day of the natural fuels such as coal gas, so gas heater also begins to be eliminated; Remaining solar water heater and storage-type electric water heater all are comparatively energy-conservation products, also therefore be widely used, but since in use hot water can not supply for a long time, cause allowing the more comfortable enjoyment of user be taken a shower.
In use hot water is not enough for solar water heater, storage-type electric water heater, and people develop the liquid heater of main installation and water outlet of water heater mouth, and this heater had not both had overpressure protection, did not have overtemperature prote yet, and the user is not had safety guarantee.
The utility model content
When aiming to provide a kind of simple and reasonable, safe and reliable, water outlet, the purpose of this utility model realizes overpressure protection, overtemperature prote; can improve solar water heater and gas heater hot water is supplied the liquid heater of unabiding deficiency, to overcome weak point of the prior art.
A kind of liquid heater by this purpose design, comprise that housing and inner chamber are used for the duct type heater of heating liquid, duct type heater two ends are respectively inlet and liquid outlet, it is characterized in that, described inlet place is provided with water flow switch, and the liquid outlet place is provided with relief valve and temperature controller.
Described water flow switch is arranged on the port of three-way connection, and the three-way connection another port is tightly connected by the inlet of inlet sealing ring and duct type heater.
An again port of described three-way connection stretches out outside the housing, is provided with the first sealing ring between itself and the housing.
Described relief valve and temperature controller are arranged on two ports of four-way connection, and the four-way connection another port is tightly connected by the liquid outlet of liquid outlet sealing ring and duct type heater.
An again port of described four-way connection stretches out outside the housing, is provided with the second sealing ring between itself and the housing.
The pressure relieving end of described relief valve stretches out outside the housing, is provided with the 3rd sealing ring between itself and the housing.
Described housing one side also is provided with fairlead, and the lead-in wire hole wall is provided with the electric wire anti-vibration ring, and the inboard corresponding fairlead of housing place is provided with electrical wire clip.
Described housing comprises fore shell and back cover, also is provided with indicator lamp on the fore shell.
The utility model is a kind of for solar water heater, the storage-type electric water heater second heating device developed of hot water deficiency in use, can allow the user can reach more comfortable, the hot water supply is more permanent.In addition; liquid heater itself has hydraulic pressure and starts; mutually combining of overpressure protection, overtemperature prote three functions; so that can be used as independent electric equipment products, uses by this liquid heater; for example, can be installed between tap and the pipeline, realize the purpose of warm water supply between gondola water faucet and the pipeline.Also have, by combining of relief valve and temperature controller, even a device failure wherein also can be protected liquid heater by another device, avoid causing personal safety.Specifically: when only having relief valve malfunctioning (can not pressure release), if water temperature constantly rises in the liquid heater, then can cause air pressure inside to rise, finally blast, but because the effect of temperature controller, when making water temperature reach the limiting temperature that temperature controller opens circuit, the liquid heater stopped heating, avoid the continuous rising because of internal pressure, and the explosion phenomenon that occurs; When only having temperature controller (can not open circuit) malfunctioning, liquid heater can not stop heating, and relief valve can in time be discharged high-temperature steam, avoids blast, and causes seriousness to burn to the user.It is simple and reasonable, safe and reliable.
