Thermal container

Abstract

The invention provides a thermal container. The whole internal space of the thermal container is divided into a first cavity and a second cavity through a partition plate, the first cavity is located on the lower portion relatively, and the second cavity is located on the upper portion relatively. A water inlet communicated with the first cavity is formed in the lower portion of the second cavity, and an air hole communicated with the second cavity and a water drawing pipe relatively stretching into the second cavity are arranged on the top of the second cavity. A water outlet correspondingly connected with the water drawing pipe is formed in the partition plate, the diameter of the water outlet is smaller than the inner diameter of the water drawing pipe, and the edge of the water outlet relatively protrudes from the surface of the partition plate around the water outlet. Accordingly, a hot water supply device can be obtained; according to the hot water supply device, after water is output, hot water in a water outlet pipeline can be made to flow back into the thermal container, the amount of residual hot water in the water outlet pipeline is effectively reduced, and the problem that hot water is still squeezed out continuously after water is output is avoided.

Description

technical field [0001] The present invention is a hot water tank, in particular, it refers to a kind of hot water that can let the hot water in the water outlet pipeline flow back into the hot tank after the water outlet operation is completed, effectively reducing the residual amount of hot water inside the water outlet pipeline, and avoiding the hot water after the water outlet operation is completed. There is still hot water being constantly squeezed out of the heat bladder. Background technique [0002] According to, generally, the hot water supply device that provides hot water, such as a water dispenser or a drinking machine, is more than equipped with a hot water tank (or called a hot cylinder) in its body. Or the heater at the bottom heats the accumulated water, and through natural extrusion, the unheated normal temperature water enters from one end, and the hot water heated by the hot water enters from the other end of the hot water relative to the water. output us...

Problems solved by technology

[0003] Furthermore, in order to facilitate operation and use, general hot water supply devices usually use pipelines (water outlet pipes) to connect the hot water at the water outlet end of the hot water tank to the outside of the body, and further provide a faucet or valve at the water outlet pipe to It is convenient for users to operate and use; however, after the general hot water supply device completes the water discharge action, it cannot completely discharge the hot water in the outlet pipe

[0004] Since the heater is still full of water, the remaining hot water in the outlet pipe cannot return to the heater, and will remain in the pipeline of the outlet pipe. In this way, when the heater is heated again, according to the principle of thermal expansion, The water that originally accumulated in the outlet pipe will be squeezed out, resulting in the phenomenon of dripping from the faucet
