water heating device

Abstract

The invention discloses a water heating device which comprises a water boiling tank. The water heating device is characterized in that the water heating device further comprises a transfer water tank and a water outlet pipe. The transfer water tank is communicated with the water boiling tank. A one-way valve is arranged on the communicated position of the transfer water tank and the water boiling tank. The water outlet pipe comprises a water pumping segment and a water discharging segment. The water pumping segment stretches into the water boiling tank and is close to the bottom wall of an inner cavity of the water boiling tank. The water discharging segment is arranged outside the water boiling tank and provided with an exhaust opening. The exhaust opening is communicated with the transfer water tank. According to the water heating device, water is boiled through the water boiling tank, the boiling water is discharged through the water outlet pipe for users to drink, and the transfer water tank supplies water to the water boiling tank timely; due to the fact that the water boiling tank is of certain capacity, the water is discharged through the water outlet pipe after being boiled in the water boiling tank, it is guaranteed that the outflow volume of the hot water is large, the requirement for the large hot water amount of the users is met, and besides, the water heating device is free of a water pump, a balance water tank and other complex structures and simpler and more reasonable in whole product structure.

[0002] Existing water heating devices have various structures and styles, such as instant drinking water heating devices, including water storage tanks, water pumps, balance water tanks, instant heating pipeline heaters (such as: quartz glass electric heating tubes) and water spouts, etc. , the water pump pumps the water in the water storage tank into the balance water tank, a part of the water in the balance water tank flows back into the water storage tank, and the other part is sent to the instant pipeline heater, and finally flows out from the water outlet; the instant drinking water heating device with the above-mentioned traditional structure , there are the following deficiencies: (1) There are many accessories involved, resulting in complex structure and cumbersome installation; (2) The height of the balance water tank is required to be close to the water outlet of the instant pipeline heater, so that the instant pipeline heater The water level in the pipe is close to the water outlet, the water in the pipe is heated to boiling, and the boiling water in the pipe can be easily overflowed by the boiling force. Therefore, the position setting of the balance water tank is relatively restricted, thereby restricting the internal structure of the product, resulting in the water storage tank. Water cannot flow naturally from high to low, but needs to be equipped with a water pump to pump water. Therefore, the product is larger in size and higher in cost, which is not conducive to the popularization and use of the product; (3) instant heating pipeline heaters, such as: quartz glass heating tubes , the outflow of hot water (boiling water) is small, which cannot meet the user’s demand for large flow of boiling water; (4) part of the water in the balance tank will flow back into the water storage tank, and the other part will flow into the instantaneous pipeline heater. The water flowing into the storage tank is easily polluted and affects drinking hygiene
