Cold water heating device for water dispenser

Abstract

The invention discloses a cold water heating device for a water dispenser; and the device comprises an inner container which is used for storing hot water and is disposed below a water inlet of the water dispenser, a piston plate, a water inlet pipe, a water outlet pipe, and a heating assembly. The piston plate is installed in the inner container in a sealed and sliding mode, the inner container is divided into a cold water cavity and a hot water cavity through the piston plate, the hot water cavity is located above the cold water cavity, and the overall density of the piston plate is larger than the density of liquid water; one end of the water inlet pipe is fixedly connected with the bottom of the inner container and communicates with the cold water cavity, and the other end of the waterinlet pipe communicates with a water dispenser water inlet; one end of the water outlet pipe is fixedly connected with the top of the inner container and communicated with the hot water cavity, and the other end of the water outlet pipe is communicated with the water dispenser water outlet; and the heating assembly is mounted at the bottom of the inner container. Hot water in the hot water cavitycan be fully utilized, the water temperature is kept stable and cannot be continuously reduced in the using process, and the continuous and stable hot water supply effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of water dispensers, and in particular relates to a cold water heating device for a water dispenser. Background technique [0002] A water dispenser is a device that discharges pure water in barrels to facilitate people's drinking. With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for water dispensers. Existing water dispenser almost all has cold water heating function, and it is generally installed with heating liner inside water dispenser, and bottled water enters heating liner inside and realizes heating by water pressure. [0003] However, during use, cold water will also enter the inner tank while the hot water is discharged, and the temperature of the hot water will continue to drop. When it reaches a certain temperature, it will not meet people's use requirements, such as brewing tea or For some beverages, hot water with ...

Problems solved by technology

[0003] However, during use, cold water will also enter the inner tank while the hot water is discharged, and the temperature of the hot water will continue to drop. When it reaches a certain temperature, it will not meet people's use requirements, such as brewing tea or For certain beverages, hot water with a higher temperature will have a better brewing effect

This leads to a low utilization rate of the hot water in the inner tank at a time, so that the user cannot obtain more hot water at a time; moreover, when more hot water is mixed with cold water, the temperature decreases, which will trigger a new round of heating , will cause some drinking water to be heated repeatedly, thereby reducing the quality of drinking water. At the same time, the heating device is frequently turned on and off, which increases the probability of failure of the heating device and shortens the service life of the heating device.
