Problems solved by technology

However, at present, the heating part of the instant drinking water device that uses thick film heating is mostly planar, and the heating efficiency of the center and edge of the heating body is different, resulting in a decrease in the heating efficiency of the heater and a shortened service life.
Moreover, the water flow is in direct contact with the low-temperature glass insulating layer of the heater, which is likely to cause electric leakage accidents, and low-temperature glass generally contains heavy metal ions, and long-term drinking is not good for the body.

Embodiment 1

[0032] Using river water as the water source, the water source may contain harmful microorganisms and heavy metal ions. It is necessary to use a membrane filter 1 to filter out the heavy metal ions. If you need to drink cold water, you can use the ultraviolet light tube 2.1 and the transparent tube 2.2 to sterilize and drink.

[0033] like figure 1 As shown in the figure, the water inlet 7 is connected to the filter 1 through a micro water pump 5 or a valve, and after passing through the transparent tube 2.2 matched with the ultraviolet light tube 2.1, it is connected to the heating part, and then output to the water outlet, and the external circuit is connected to the heating part through the control part. Partial or miniature water pump 5;

[0034] The principle is that the river water is pumped into the membrane filter 1 from the water inlet 7 through the micro water pump 5 . If you drink hot water, you do not need to open the ultraviolet disinfection light pipe, the water...

Embodiment 2

[0037] Using river water as the water source, the water source may contain harmful microorganisms and heavy metal ions. It is necessary to use a membrane filter 1 to filter out the heavy metal ions. If you need to drink cold water, you can use the ultraviolet light tube 2.1 and the transparent tube 2.2 to sterilize and drink.

[0038] like Figure 2a As shown, in order to save costs, the micro water pump 5 in Example 1 is replaced by a small kettle 11 . The kettle 11 is placed above the heating barrel 3, so that the kettle 11 is connected to the filter 1 through the valve 6; The control of the control valve 6 can be either automatic or manual. Other parts are not significantly different from Example 1.

Embodiment 3

[0040] See Figure 2b , using tap water as the water source, when the harmful microorganisms and heavy metal ions in the water source meet the standards, the design can be simplified, and there is no need to use the water purification system composed of membrane filter 1, ultraviolet light tube 2.1 and transparent tube 2.2. akin. For general tap water, it is not recommended to drink cold water directly.

[0041] like Figure 2b As shown, the tap water is pumped into the heating part from the water inlet 7 through the micro water pump 5, and when the water flows through the cylindrical guide body 4 with a threaded channel, it contacts the stainless steel substrate 3.4 of the inner wall of the heating barrel 3, and the heating barrel 3 is controlled by the control system 9. The heating power and the size of the water flow are controlled by the micro water pump 5, so that the temperature of the water can be controlled.

[0042] Compared to Example 1, there is no water purifica...

Abstract

The invention discloses an instant drinking water device using a thick film for heating. A thick-film resistor is used in the heating part of the device for heating and a heating barrel is a hollow barrel-shaped structure. Water flow directly contacts a stainless base on the inner wall of the heating barrel through a column-shaped guiding object. Compared with the traditional electric heating tube heating, the device has the advantages of fast heating speed, high heating efficiency and energy saving and environmental protection; and meanwhile, the invention also solves the problem of uneven heating in the traditional flat thick film. Besides, water flow cannot directly contact a low-temperature glass insulating layer on the outer surface of the thick film heating barrel, thus heavy metal ion poisoning and leakage accident caused by corrosion can be prevented and safety performance can be obviously improved. The device provided by the invention has simple manufacturing process and low requirements on the device, is easy to obtain raw materials and industrialize.

Description

technical field [0001] The invention relates to an instant electric heating device, in particular to a barrel-shaped thick film heating system, a water purification system, a water flow conveying system and an electrical control system of the instant drinking water device. Background technique [0002] Water is the source of life, and one cannot but drink water. At present, most of the heat-storage drinking water devices sold on the market include an inner tank with a heating function, and the water in the inner tank is usually heated for use. This kind of drinking water device controls the heating and power off of the system through a thermostat, and has the problem of repeated heating, and the heating efficiency is not high. Moreover, due to the large thermal capacity of the water in the water tank, the drinking device needs to be turned on for more than 3 minutes before hot water can be produced, and the acceleration speed is also slow. [0003] The instant hot drinking...
