technical field

The invention relates to the technical field of gas instant water heaters, in particular to the water purification and sewage discharge technology of gas instant water heaters.

Background technique

Because municipal tap water is transported through long pipelines and treated with chlorine gas in waterworks, the water will contain rust, residual chlorine and other impurities that affect water quality. In some areas, the water hardness is relatively high, especially in the north. Hard water not only affects the comfort and health of users when bathing, but also causes pipeline blockage. At present, there are few gas water heaters with water quality treatment on the market. Even if there are, industrial adsorbents are used for single water quality treatment. Limited by the amount of adsorbents, sustainability cannot be achieved. It may even cause clogging due to the adsorption of a large amount of impurities by the adsorbent, reducing the water flow, which is not conducive to the comfort of the user for bathing.

In order to achieve the above purpose, the patent of the present invention adopts the following technical scheme: a gas water heater capable of intelligent water purification and sewage discharge, including a gas water heater body, a water inlet pipe and an outlet pipe are arranged in the gas water heater body, and the water inlet and outlet pipes are connected to the heat exchanger , it is characterized in that, the water inlet pipe section of the gas water heater body is provided with a pre-filter device and a flow sensor, and the pre-filter device is not only connected with the water inlet and outlet, but also has a filter between the water inlet and outlet of the pre-filter device. The pipeline before the filter screen is also connected to the sewage pipe. There is a ball valve switch on the sewage pipe. Two modes are realized through the pre-filter device. When the switch is closed and the waterway is open, it is the water purification mode. For blowdown mode.

As a further illustration of the above solution, the filter screen of the pre-filter device is a tubular structure, one end of the filter screen of the tubular structure is connected, and the outer part of the filter screen of the tubular structure is equipped with a water sealing pipe, and the water sealing pipe communicates with the water outlet end.

Further, the precision of the filter screen is 5 microns to 100 microns, and filter screens of different specifications can be used according to different water quality.

The body of the gas water heater is provided with a controller, the ball valve switch is an electromagnetic switch, and the electromagnetic switch and the flow sensor are electrically connected to the controller, so that when the water heater starts the water purifying operation for a period of time, the water circuit of the water heater is closed and the ball valve switch can be automatically opened. At this time, the impurity attached to the filter screen is impacted by the water flow, so that the impurity is discharged from the sewage pipe.

Compared with the prior art, a gas water heater capable of intelligent water purification and sewage discharge provided by the patent of the present invention has the following beneficial effects:

1. Inhibit the formation of scale, eliminate the influence of impurities on the water flow sensor, and avoid pipeline blockage, especially the shower;

2. The high-precision filter is used inside the device, which can effectively purify the water quality, remove impurities and dirt, inhibit the growth of bacteria, and create a safe, healthy and comfortable bathing environment;

3. Less wearing parts, no consumables, low operating costs, and simple operation and management;

4. The design structure is simple, and the filter screen can be used for life without replacement.

detailed description

Below in conjunction with accompanying drawing and embodiment the patent of the present invention will be further described.

As shown in Figure 1, a gas water heater capable of intelligent water purification and sewage discharge according to the present invention includes a gas water heater body 1, a gas water heater body 1 is provided with a water inlet pipeline 5 and a water outlet pipeline 6, and the water inlet and outlet pipelines are connected to a heat exchanger 2. The water inlet pipe section 5 of the gas water heater body 1 is provided with a pre-filter device 4 and a flow sensor 3. The pre-filter device 4 is not only connected to the water inlet and outlet 41, 42, but also between the inlet and outlet of the pre-filter device. Filter screen 43 is also arranged between, and the precision of described filter screen 43 is 5 micron～100 micron, can adopt the filter screen of different specification according to water quality difference, the pipeline before filter screen 43 is also connected with blowdown pipe 44, on the blowdown pipe 44 There is a ball valve switch 46, and two modes are realized through the pre-filter device 4. When the switch 46 is closed and the waterway is open, it is the water purification mode. When the switch 46 is opened and the waterway is closed, it is the sewage discharge mode. The specific structure is that the pre-filter The filter screen 43 of the filter device 4 is a tubular structure, one end of the tubular structure filter screen 43 is connected to the sewage pipe 44, and the other end is connected to the water inlet 41, and the outer set of the tubular structure filter screen 43 is a water sealing pipe 45, which communicates with the water outlet. , communicate with the water inlet port through the filter screen 43.
