Water heating device with automatic replenishment

Abstract

The invention discloses a water heating device with the automatic water adding function. The water heating device with the automatic water adding function comprises a boiling water tank, a transfer water tank and a water outlet pipeline, wherein an outlet and a water adding port are formed in the transfer water tank, the outlet of the transfer water tank is connected with an inlet of the boiling water tank, one end of the water outlet pipeline is arranged in the boiling water tank and extends to be close to the bottom wall of the boiling water tank, the other end of the water outlet pipeline extends out of the boiling water tank, and an automatic water adding device used for sealing or opening the water adding port by means of rising or falling of the water level in the transfer water tank is arranged on the transfer water tank. According to the water heating device, water is boiled by means of the boiling water tank, and the boiled water tank is discharged through the water outlet pipeline so as to be used by users; in addition, through the additional arrangement of the transfer water tank, the automatic water adding function is achieved, and water can also be added into the boiling water tank, so that sufficient water is supplied to the boiling water tank; due to the fact that water in the boiling water tank is discharged through the water outlet pipeline after being boiled, it is guaranteed that the outflow volume of hot water is large, and the requirement of the users for a large amount of drinking water is met; in addition, the complicated structures such as a water pump and a balance water tank are not needed, and thus the whole water heating device is simper and more reasonable in structure.

Description

technical field [0001] The invention relates to a water heating device, in particular to a water heating device capable of automatically replenishing water. Background technique [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 outlets, 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 he...

[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 outlets, 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 water storage tank is easily polluted and affects drinking hygiene; (5) There is no transfer water tank, and there is no automatic water replenishment device on the transfer water tank to realize the automatic water replenishment function of the transfer water tank
