Description

Technical Field

[0001] The utility model relates to the field of domestic water tanks, in particular to a domestic water tank with a guide plate installed. Background Art

[0002] The domestic water tank is an important water storage device in the secondary water supply system. The water quality of the secondary water supply is directly related to the safety of residents' domestic water use. When the inlet and outlet pipes of the domestic water tank are close to each other, the water entering the water tank through the inlet pipe will flow out of the water tank through the outlet pipe faster, while the water in the water tank that is far away from the outlet pipe may be retained. If the retention time exceeds 48 hours, the water quality of the water tank will deteriorate, affecting the quality of drinking water, thereby indirectly affecting the safety of residents' domestic water use. Therefore, in order to solve this problem, a guide plate can be installed in the water tank to allow the "advanced" water to "go out first" along the diversion direction, avoiding water short-circuiting and dead corners, which will cause the drinking water in the water tank to be retained for a long time, causing secondary pollution of the drinking water.

[0003] After searching, a diversion type domestic water supply tank is disclosed in the announcement number: CN208121878U, which belongs to the field of domestic water tanks and aims to provide a diversion type domestic water supply tank. The key points of its technical solution are: it includes a box body and a water inlet and a water outlet opened on the box body, and a guide plate is provided in the box body, the guide plate is located between the water inlet and the water outlet, the bottom of the guide plate is tightly attached to the bottom of the box body, one end of the guide plate is connected to the inner wall of the box, and there is a gap between the other end and the inner wall of the box; the advantage is: increasing the water flow velocity in the box body, thereby reducing the dead corners of the water tank, and further reducing the secondary pollution of the water in the box body.

[0004] Although the above application also discloses a diversion-type domestic water tank, the water inlet of the patent is arranged at the bottom of the tank, which poses a risk of backflow contamination in the water inlet pipe. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a domestic water tank equipped with a guide plate, aiming to improve the problem that drinking water is easily contaminated due to long-term retention of drinking water in the water tank. Compared with the prior art solution of setting the water inlet at the bottom, the water inlet pipe is set at the top of the tank body, thereby avoiding the risk of backflow contamination of the water inlet pipe.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a domestic water tank with a guide plate installed, comprising a water tank, a water inlet and a water outlet of the water tank, and a guide plate, wherein the water inlet is arranged at the top of one side wall of the water tank, the water outlet is arranged at the bottom of the other side wall of the water tank, one side of the guide plate is connected to one side wall of the water tank, and the other side of the guide plate is connected to the other side wall of the water tank;

[0016] Through the above technical solution, the first filter can filter impurities, and the filtered impurities fall on the second filter. The apertures of the first filter and the second filter are the same. When the collection component is removed from the box, the second filter can carry the impurities, allowing water to flow out through the second filter. The second filter is inclined to prevent the water flow from washing away the impurities, making it convenient to regularly clean the filter and the filtered impurities.

[0017] Preferably, a first positioning arc plate and a second positioning arc plate are respectively provided on both sides of the positioning support frame, and the first positioning arc plate and the second positioning arc plate are both arc-shaped, and one side of the first positioning arc plate can fit the crest or trough of the wavy first S-shaped guide plate, and one side of the second positioning arc plate can fit the crest or trough of the wavy second S-shaped guide plate.
