Drinking water heating device with pre-heating function

Abstract

The invention relates to a drinking water heating device, in particular to a drinking water heating device with a pre-heating function, which comprises a seat body, a water outlet nozzle and an instant-heating heater, wherein the instant-heating heater is provided with an inlet and an outlet; the inlet is connected with a water inlet pipeline; the outlet is communicated with the water outlet nozzle. The drinking water heating device is characterized in that: the drinking water heating device also comprises a pre-heater; the pre-heater is arranged on the water inlet pipeline; the drinking water heating device pre-heats the water entering the instant-heating heater so as to primarily increase the water temperature; and the primarily heated water can be quickly heated to a boiling point or a temperature close to the boiling point after being heated by the instant-heating heater so that the heating time is saved and large water outlet flow can be ensured for drinking without increasing power of the instant-heating heater. The drinking water heating device is simple and rational in structure, simple and safe in use, low-carbon and energy-saving, and long in service life, and can satisfy various different drinking requirements of people, for example, making tea, making coffee and the like.

Description

technical field [0001] The invention relates to a drinking water heating device, in particular to a drinking water heating device with a preheating function mainly for making tea. Background technique [0002] Such as Figure 8 As shown, it is an existing drinking water heating device, which only has an instant heater 2 to heat the water in the water tank 7. This drinking water heating device has the following disadvantages: (1) In view of the existing There is only one heater (instant heater) on the drinking water heating device. In order to obtain water that meets the high-temperature drinking requirements (such as the temperature required for making tea), it can be achieved by three methods. One is by extending the instant heater. The heating time of the heater, but this method makes the instant heater lose its original advantages of rapid heating, and cannot meet people's various needs; the other is to increase the power of the instant heater, but this The method is not...

[0002] like Figure 8 As shown, it is an existing drinking water heating device, which only has an instant heater 2 to heat the water in the water tank 7. This drinking water heating device has the following disadvantages: (1) In view of the existing There is only one heater (instant heater) on the drinking water heating device. In order to obtain water that meets the high-temperature drinking requirements (such as the temperature required for making tea), it can be achieved by three methods. One is by extending the instant heater. The heating time of the heater, but this method makes the instant heater lose its original advantages of rapid heating, and cannot meet people's various needs; the other is to increase the power of the instant heater, but this The method is not only limited by the maximum rated power of the product's own industry standard, but also the general household occasions cannot bear the excessive power of electrical products; another method is to reduce the water flow (ie: reduce the flow through the instant heater) Unit water flow), but this approach, in view of the low water output, cannot meet people's drinking requirements for high water output

Therefore, in many cases, users who use this drinking water heating device also configure an additional electric kettle for secondary heating. To a large extent, it has affected the promotion and use of the product; (2) In view of the separate arrangement of the water tank 7 and the seat body 9, a water tank valve is provided at the bottom of the water tank 7. When the water tank is placed on the seat body and the water tank valve and the water pump 8 When connected, the water tank valve will be pushed open by the thimble of the water outlet to realize the communication between the water pump and the water tank. However, when the water tank moves away from the seat body, the water tank valve will automatically close, but there will be water backflow overflowing at the water outlet of the seat body 9, and residual The surface of the seat body 9 affects the cleanliness of the panel, and even causes bacteria to enter the water pipe from the water outlet, which is harmful to health; (3) In addition, the water level of the water tank is easy to be ignored. Once the water level is too low, the user starts the drinking water heating device and easily causes the water pump to run idly damage, as well as dry heating of the instant heater, reducing the service life; when the water level is too high, it is easy to cause the water in the water tank to overflow, which also affects the cleanliness and hygiene of the product
