[0002] Most existing drinking water equipment has a heating water tank, and the water in the water tank is heated by setting a heating component in the heating water tank. However, for larger heating water tanks, due to the limited heating area of the heating component, the water near the heating component attachment is usually boiled, but the water far away from the heating component is not yet boiled. This will cause the water heating time to be long and cause the boiling water inside to be repeatedly heated and boiled, forming "thousand-boiled water".
[0003] In order to solve this technical problem, a Chinese utility model patent with patent number ZL 202322285001.2 (authorization announcement number CN220707720U) discloses a water mixing prevention drinking water equipment separated by a heating water tank and a boiling water tank. The heating water tank includes a box body, and the interior of the box body is divided into a boiling water area and a heating area distributed up and down by a partition.

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] The drinking water equipment in this embodiment includes a heating water tank. The drinking water equipment in this embodiment includes but is not limited to a water dispenser or a water purifier.
[0029] like Figures 1 to 5 As shown, the heating water tank includes a box body 1, a heating component and a water retaining component 3, wherein the heating component and the water retaining component 3 are both arranged in the box body 1, and the heating component is used to heat the water in the water storage chamber 10; the box body 1 is hollow inside to form the water storage chamber 10, and the box body 1 is provided with a water inlet 1a, a sewage outlet 1b, an exhaust port 1c and a drain port 1d; Figure 1 As shown, the box body 1 in this embodiment is square, the water inlet 1a, the sewage outlet 1b and the exhaust port 1c are all arranged on the bottom wall of the box body 1, the drain outlet 1d is arranged on the side wall of the box body 1, and the outer wall of the box body 1 is also provided with a mounting bracket 6, through which the box body 1 can be connected to an external foundation (the external foundation can be a wall or a drinking water equipment shell).
[0030] The box body 1 is also equipped with a water level detection unit and a temperature detection unit 51 that can extend into the water storage chamber 10. There are three water level detection units in this embodiment, namely a high water level probe 41, a middle water level probe 42 and a low water level probe 43. Each high water level probe 41, a middle water level probe 42 and a low water level probe 43 extends into the water storage chamber 10 from the top of the box body 1; the above-mentioned temperature detection unit 51 is a temperature sensing probe, and the temperature detection unit 51 is used to detect the water temperature in the box body 1 in real time; the high water level probe 41, the middle water level probe 42, the low water level probe 43 and the temperature detection unit 51 are all electrically connected to the controller. In addition, the outer periphery of the box body 1 is also coated with a heat preservation layer and / or a thermal insulation layer, which can be a plastic film or a high temperature resistant aluminum foil paper, and the heat preservation layer can be a polyurethane foam layer to play a role in heat preservation of the box body 1 and reduce heat loss.
[0031] The heating assembly includes a heating tube 2 disposed in the water storage chamber 10. The heating tube 2 has a tortuous shape. The area enclosed by the heating tube 2 along the fluid flow direction is substantially parallel to the wall of the box body 1 where the water inlet 1a is located. In addition, a spiral protrusion 21 is provided on the outer peripheral wall of the heating tube 2. The protrusion 21 is multiple and spaced apart on the outer peripheral wall of the heating tube 2. Figure 3 and Figure 4 As shown, the heating tube 2 in this embodiment is tortuous and M-shaped. Figure 4 As shown, each protrusion 21 is arranged on the straight section of the heating tube 2, so that the heating area of the straight section can be increased.
[0032] The water retaining assembly 3 includes a water retaining member that is open toward the wall of the box body 1 where the water inlet 1a is located. The open end of the water retaining member is connected to the wall of the box body 1 where the water inlet 1a is located, and the interior of the water retaining member is in fluid communication with the water inlet 1a. The outer wall of the water retaining member is provided with a plurality of water holes that penetrate the wall thickness. In order to further reduce the flow rate of the incoming water, there are at least two water retaining members, namely a first water retaining member 31 and a second water retaining member 32. The first water retaining member 31 is arranged inside the second water retaining member 32 and a water gap 30 is left between the first water retaining member 31 and the inner peripheral wall. The water inlet 1a is located inside the first water retaining member 31.
[0033] In this embodiment, the first water retaining member 31 and the second water retaining member 32 are both box-shaped, and the water holes on the first water retaining member 31 are marked as first water holes 311, and the first water holes 311 are spaced apart on the two opposite side walls of the first water retaining member 31, and the water holes on the second water retaining member 32 are marked as second water holes 321, and the second water holes 321 are spaced apart on the two opposite side walls of the second water retaining member 32, and the side wall of the first water retaining member 31 where the first water hole 311 is located is substantially perpendicular to the side wall of the second water retaining member 32 where the second water hole 321 is located. Figure 5As shown, in this embodiment, the first water hole 311 is opened on the two short side walls of the first water retaining member 31, and there is no first water hole 311 on the two long side walls of the first water retaining member 31. The second water hole 321 is opened on the two long side walls of the second water retaining member 32, and there is no second water hole 321 on the two short side walls of the second water retaining member 32.
[0034] In addition, the aperture of the first water hole 311 is smaller than the aperture of the second water hole 321. In this case, if the water entering the housing 1 from the water inlet 1a changes from the small aperture of the first water hole 311 to the large aperture of the second water hole 321, the water outlet pressure will be reduced. At the same time, since the side wall of the first water retaining member 31 where the first water hole 311 is located is substantially perpendicular to the side wall of the second water retaining member 32 where the second water hole 321 is located, the water entering the housing 1 from the water inlet 1a rotates approximately 90° inside the first water retaining member 31 and the second water retaining member 32 before flowing out, which greatly reduces its flow rate, so that the cold water flowing out from the second water hole 321 can slowly mix with the hot water in the housing 1, so that the cold water entering from the water inlet 1a can be heated faster, so that the water temperature in the housing 1 is more uniform.
