Problems solved by technology

Patent No. ZL02149437.1, ZL91103310.6 and patent application CN200610149039.5 disclose several forms of water boilers, all of which use the method of separating or separating boiling water heating and hot water storage into two containers. It solves the problem of yin and yang water, but at the same time, it also creates the problem of controlling the temperature of the boiled water outlet, that is to say, the outlet temperature of the boiled water cannot be set and predicted. It is inconvenient to come, and the structure of the equipment is complex, the process is cumbersome, and the manufacturing difficulty and cost are high
[0004] Chinese Patent No. ZL 200620054852.X discloses a water boiler, which uses high and low liquid levels to automatically control the start and stop of the heating tube, and uses the method of setting high temperature and low temperature probes at the bottom to control temperature and replenish water, but there are still the following problems: The temperature sensor can only control the start and stop of the heating pipe, but does not control the amount of water replenishment. The water replenishment process does not stop until the water level of the heating container is high, and the upper water replenishment method is still used, which not only does not completely solve the problem of yin and yang water, but also It is necessary to wait until the water temperature of the entire heater is heated to the set temperature before the hot water can be effectively supplied, and the interval between water supply is relatively long
But there are still the following deficiencies: (1) the heater adopts a conventional container shape, not only the cycle of stepping heating is longer, but also the water at the corners of the bottom of this straight cylindrical container cannot be effectively transported to the upper layer, so that it cannot be effectively and timely The supplement forms a dead angle around the bottom of the heating container to store dead water, and because the water temperature of this part of the water is low, it is easy to cause the growth and reproduction of bacteria and microorganisms, thereby affecting the water quality, so there are obvious convection dead angles and low temperature dead water phenomenon; (2) The design of the upper and lower positions of the electric heating tube, temperature sensor, and water outlet is not reasonable enough, and there is obviously a large deviation between the actual water temperature of the outlet water, the water temperature measured by the temperature sensor, and the water temperature around the electric heating tube. It will lead to improper control of the heater and inaccurate outlet water temperature, threatening the operation of the equipment and the safety of the user; (3) The water replenishment port is set on the side of the heating container, and the water replenishment is uneven and will form strong convection, which will damage the original heating container. There is a natural stratification phenomenon of water temperature, which also produces a considerable degree of yin and yang water phenomenon; (4) There is no temperature control on the outlet water, and the water that does not reach the set temperature will flow out of the supply at any time, affecting the use and threatening the safety of drinking water; (5) When the water heater is heated, the steam inside the heating container may accumulate, which will affect the safety of equipment operation, and may cause the steam with pressure to be ejected from the water outlet along with the water, threatening the safety of the water taker

Abstract

The invention provides a liquid heating device. The liquid heating device comprises a heating container which is equipped with a water replenishing pipe and a water outlet pipe, wherein, the water replenishing pipe is connected with an external water source via a water inlet valve; the heating container is internally equipped with an electric heating tube and a temperature sensor; the bottom of the side wall of the heating container is in a straight cuboid shape, wherein the bottom of the opposite two side wall is separately inward tilt and form a taper closing; a low-liquid-level sensor and a high-liquid-level sensor are also respectively arranged in the heating container; the water replenishing pipe extends into the heating container from the bottom thereof; the electric heating tube and the temperature sensor are sequentially arranged above an outlet of the water replenishing pipe; signal output terminals of the temperature sensor, the low-liquid-level sensor and the high-liquid-level sensor are respectively and electrically connected to a control unit; and an output terminal of the control unit is connected to a control end of the water inlet valve. By operating and controlling the liquid heating device, liquid can be stably heated in a stepping manner; and meanwhile the liquid heating device has the characteristics of high space utilization ratio, no stored water dead corner, high heating efficiency, reliable supply water temperature and the like, thus being efficient, sanitary, safe and reliable.

Description

technical field [0001] The invention relates to a liquid heating device, in particular to a step-by-step heating, fully automatic and stable liquid electric heating device. Background technique [0002] Traditional liquid heaters or water boilers usually use top water replenishment, the heating container is heated to the set temperature after water replenishment is completed, and the water is cooled and then reheated. Therefore, there is a common and prominent hot and cold water mixing problem, which is commonly known as the problem of yin and yang water. Not only the temperature of the outlet water is uncertain, but also the safety and health of drinking water will be affected. [0003] For this reason, someone has carried out continuous innovation and improvement, and while obtaining some effective results, there are still many related problems. Patent No. ZL02149437.1, ZL91103310.6 and patent application CN200610149039.5 disclose several forms of water boilers, all of wh...
