Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, and in particular relates to a pipeline water dispenser capable of quickly delivering hot water. Background Art

[0002] Pipeline water dispensers are generally used in homes, offices, schools, etc., and are used in conjunction with water purification equipment. They have a built-in water tank. Clean water is placed in the tank in advance and then heated by a heating tank. It can provide normal temperature water and hot water for drinking.

[0003] In the prior art, there are also pipeline water dispensers that can prepare warm water of various temperatures. For example, Chinese utility model patent application number 201821501742.2 discloses a safe pipeline water dispenser with stepless water temperature adjustment. In addition to normal temperature water and boiling water, it can also prepare warm water with stepless temperature adjustment for drinking.

[0004] However, for the demand for a large amount of hot water in a short period of time, this type of pipeline water dispenser is limited by the speed of generating boiling water and seems powerless. Now there is an urgent need for a pipeline water dispenser that can generate a large amount of hot water or even boiling water in a short period of time. Utility Model Content

[0005] In order to solve the above technical problems, the present application further improves the internal structure of the existing pipeline water dispenser, so as to achieve the effect of generating a large amount of hot water in a short period of time. The purpose of the utility model is to provide a pipeline water dispenser that can quickly produce hot water.

[0006] The specific technical solutions are described below:

[0007] The pipeline water dispenser with quick hot water supply includes:

[0008] A water inlet part is connected to the main water inlet of the main water tank through a pipeline, and a water inlet valve is arranged on the pipeline between the water inlet part and the main water inlet;

[0009] The main body water tank is also provided with a main body water outlet, the main body water outlet is connected to the heating inlet of the heating element through a pipeline, and a main body water pump is provided on the pipeline between the main body water outlet and the heating inlet;

[0010] The heating element is also provided with a heating outlet, which is connected to the hot water inlet and the water outlet of the hot water tank through pipelines, and a hot water valve is provided on the pipeline between the heating outlet and the hot water inlet;

[0011] The hot water tank is also provided with a hot water outlet, which is connected to the water outlet through a pipeline, and a hot water pump is provided on the pipeline between the hot water outlet and the water outlet.

At the same time, it is also convenient to adjust the flow rate by controlling the power; the water inlet valve a and the hot water valve d are both solenoid valves.

[0045] Reference Manual Attached Figure 2 When hot water needs to be prepared normally, it is only necessary to heat the heating element 3, and the heating outlet 3.2 thereof outputs hot water;

[0046] The most basic technical effects of this embodiment include: by adding a hot water tank 4 at the outlet of the heating element 3, hot water can be stored in advance, so that when a large amount of hot water is needed, the hot water in the hot water tank 4 can directly provide a large amount of hot water to the water outlet 5 without further heating;

[0047] In a further technical effect, the hot water in the hot water tank 4 can be used as a supplement to output hot water to the water outlet 5 together with the heating outlet 3.2 of the heating element 3, further achieving the purpose of generating a large amount of hot water in a short time;

[0048] A further technical effect is that when warm water needs to be prepared, the heating element 3 is turned off. At this time, the heating outlet 3.2 provides cold water, while the hot water outlet 4.2 provides hot water. The two can be mixed to form warm water. The hotness of the warm water can be adjusted by controlling the power of the main water pump b and the hot water pump d-diaphragm pump, and then controlling its flow rate.

[0049] The specific functions are as follows:

[0050] ① A branch line to the hot water tank 4 is set behind the heating element 3. Through the APP setting, the boiling water generated by the heating element 3 enters the hot water tank 4 through the hot water valve c on the branch line;

[0051] ② When the hot water is discharged at a large flow rate, the hot water tank 4 can supply water alone, or the heating element 3 can generate boiling water, and the hot water pump d will make the boiling water in the hot water tank 4 flow out from the water outlet 5;

[0052] ③ When hot water is discharged at a large flow rate and warm water is needed, the normal temperature water in the main water tank 2 is mixed with the boiling water of the hot water pump d through the main water pump b. By controlling the power P of the main water pump b, the discharge of warm water at different temperatures can be achieved.
