Description

Gas water heater

Technical Field

The utility model belongs to the technical field of the water heater, especially, relate to a gas heater.

Background

After the gas water heater is used for a long time, the heat efficiency is reduced, and one important factor is that a large amount of scale exists in a heat exchanger pipeline, so that heat transfer is influenced. This is because the gas water heater must retain a portion of the hot water in the line after each use, most of which is present in the heat exchanger. Because the water body contains more mineral substances or other impurities, when the water temperature is reduced, water scale is easy to separate out from the water body and is adsorbed on the wall of the heat exchanger pipe. When the shower head is used for a long time or the water quality of a user is poor, scale accumulation is easily caused, the heat transfer efficiency of the heat exchanger is reduced, the heating time is too long, and the shower experience is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the problems that exist among the prior art to a certain extent at least, for this reason, the utility model provides a gas water heater effectively solves the problem that causes the thermal efficiency to descend because of the heat exchanger scale deposit is more.

The above purpose is realized by the following technical scheme:

the utility model provides a gas water heater, includes combustor, heat exchanger, water inlet pipe and outlet pipe way, the heat exchanger is located on the combustor be provided with the heat transfer pipeline on the heat exchanger, the both ends of heat transfer pipeline respectively with the water inlet pipe the outlet pipe way is connected be equipped with the scrubbing ware in the heat transfer pipeline.

In some embodiments, the dirt separator is disposed within the heat exchange conduit proximate to the water outlet conduit.

In some embodiments, the heat exchange line comprises a U-shaped tube, and the dirt separator is disposed in the U-shaped tube and near a connection of the U-shaped tube and the water outlet line.

In some embodiments, the dirt separator is fixed in the U-shaped tube by brazing.

In some embodiments, the scrubber is an electronic scrubber.

In some embodiments, the electronic dirt separator includes a positive electrode and a negative electrode made of metal, wherein the negative electrode is used for generating alkaline ions and the positive electrode is used for generating acidic ions.

In some embodiments, the voltage generated during use of the electronic trash is less than the safe voltage of a human body.

Compared with the prior art, the utility model discloses an at least including following beneficial effect:

1. the utility model discloses a gas heater is used for dispelling the incrustation scale through being equipped with the dirt separator in heat transfer pipeline, can effectively reduce the inefficiency problem that the water heater brought after working for a long time, also can purify the water simultaneously, has functions such as antibiotic disinfection, deodorization concurrently.

Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.

The first embodiment is as follows: as shown in fig. 1, 2 and 3, a gas water heater includes a burner 1, a heat exchanger 2, a water inlet pipeline 3 and a water outlet pipeline 4, the heat exchanger 2 is disposed on the burner 1, the heat exchanger 2 is provided with a heat exchange pipeline, two ends of the heat exchange pipeline are respectively connected to the water inlet pipeline 3 and the water outlet pipeline 4, a dirt separator 5 is disposed in the heat exchange pipeline, and the dirt separator 5 is electrically connected to a control panel (not shown) or a control circuit (not shown) of the gas water heater, which should be understood by those skilled in the art.

Furthermore, the dirt separator 5 is disposed in the heat exchange pipeline at a position close to the water outlet pipeline 4, considering that the water outlet pipeline 4 of the water heater has the highest temperature when the water heater is in operation, and scale is most easily precipitated at the highest temperature.

In this embodiment, it is preferable that the heat exchange pipeline includes a U-shaped pipe, which can improve the heat exchange efficiency of the water heater, as will be understood by those skilled in the art.

Further, the dirt separator 5 is arranged in the U-shaped pipe, is close to the joint of the U-shaped pipe and the water outlet pipeline 4, and is fixed in the U-shaped pipe through brazing, so that the connection reliability of the dirt separator 5 is ensured.

Further, the dirt separator 5 is an electronic dirt separator, and includes a positive electrode and a negative electrode made of metal, wherein the negative electrode is used for generating alkaline ions, the positive electrode is used for generating acidic ions, and the working principle is as follows: the electronic dirt separator is provided with a positive electrode and a negative electrode which are made of noble metal, when the electronic dirt separator is started, a certain voltage and current can be kept between the positive electrode and the negative electrode, and a part of water remains in the water heater after a user uses the water heater every time, so that a conductive loop can be formed. When the electronic dirt separator works, alkaline ions can be generated at the negative electrode and can be combined with impurities adsorbed on the pipe wall of the water heater, so that the accumulation of the impurities is reduced powerfully, and the scaling phenomenon is reduced. Meanwhile, the acid ions can be generated at the anode, and the composite material has the functions of antibiosis and disinfection and deodorization. After the decontamination is finished, the gas water heater can be opened, and the removed mineral substances are directly washed away. The device does not have any side effect to whole water, in addition, because the voltage that produces in the use is less than human safe voltage far away, therefore safe and reliable.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
