Pipeline machine

Abstract

The invention discloses a pipeline machine which comprises a hot pot, a regulating water reservoir, a breathing tube and a hot water outlet, wherein the position of the regulating water reservoir is higher than that of the hot pot; the top of the hot pot is provided with a water outlet pipe communicated with the hot water outlet; a water inlet at the bottom of the hot pot is communicated with a hot pot water inlet valve through a hot pot water inlet pipe; and the regulating water reservoir is communicated with the hot pot water inlet pipe through the breathing tube. In the invention, a water level control device is not needed in the regulating water reservoir, thereby the manufacturing cost is reduced; meanwhile, normal-temperature drinking water with pressure directly flows out through a normal-temperature water outlet valve, thus the problem of easy bacteria growth of a water reservoir of a traditional pipeline machine is solved, and the safety of the drinking water is improved; and swelling water generated by the hot pot in a heating process can flow to the regulating water reservoir, thus all the swelling water can be recycled, and the effects of saving energy and water are achieved.

Description

technical field [0001] The present invention relates to pipeline machines. Background technique [0002] The water dispenser used in conjunction with the pressure water purifier is also called a pipeline machine. There are two basic types of pipeline machines: [0003] The first type of structure is to install a water storage tank above the hot tank. The water under pressure is decompressed by the water inlet valve and then flows into the storage tank for storage. There is also a device for controlling the water level in the water storage tank. The water pipe is connected to the bottom of the hot tank and the normal temperature water outlet pipe is connected to the normal temperature water outlet valve of the water dispenser. The top of the hot tank is provided with a water outlet pipe connected to the hot water outlet valve of the water dispenser. The problems of this type of pipeline machine are: 1. The exhaust pipe connected to the upper part of the water storage tank a...

AI Technical Summary

Problems solved by technology

The problems of this type of pipeline machine are: 1. The exhaust pipe connected to the upper part of the water storage tank and the water storage tank is set above the hot tank will cause the temperature of the water in the water storage tank to change (or be called temperature rise). Usually, the water temperature in the water storage tank will increase. It reaches close to 35°C, which is a temperature at which bacteria can multiply rapidly, and eventually the microorganisms in the normal temperature water taken from the water storage tank by the user exceed the standard; 2. The manufacturing cost of the water storage tank and its water level control device is relatively high

The problems of this type of pipeline machine are: 1. During the heating process of the hot tank, the volume of the water will expand significantly, and the water volume increased by the expansion will be discharged from the exhaust pipe into the sewer, which wastes both energy and drinking water; 2. For the situation where the pressure of the water source is very low, there will be no low-pressure area in the siphon check valve. When the user takes hot water, most of the hot water flowing out of the outlet pipe of the hot tank will flow to the hot water outlet of the pipeline machine. Still a small part will flow from the exhaust pipe to the sewer, causing a waste of both energy and drinking water

[0005] Another common problem with traditional pipeline machines is that once scale builds up in the hot tank, the machine can only be disassembled by professionals for cleaning, because there is no liquid filling device that is convenient for adding liquid to the hot tank
