Central constant temperature water supply beverage preparation device

Abstract

The present invention provides a central constant temperature water supply beverage preparation device, which mainly uses a water heater that can preheat the internal water storage to a set temperature, draws hot water through a water supply main pipe and delivers it to at least one water supply manifold, Various types of beverage preparation modules can be respectively installed on each water supply manifold, so that the hot water can interact with the beverage materials preset in the beverage preparation modules to form a beverage. There is a return pipe between the end of the water supply main pipe and the water heater, and a temperature detector and a return solenoid valve are arranged in the return pipe; when the water supply is in the initial stage, close the solenoid valves of each water supply manifold, and open the return solenoid valve, so that the water supply main The hot water in the pipe directly flows back into the water heater through the return pipe until the temperature detector detects that the water temperature in the return pipe reaches the set temperature, and then opens the solenoid valves of the water supply manifolds to perform beverage preparation program.

Description

technical field [0001] The invention relates to a beverage preparation device, which mainly uses a central water supply system to provide constant-temperature hot water to each beverage preparation module for beverage preparation procedures. Background technique [0002] Beverage preparation devices are used for brewing coffee, tea or other beverages. The existing beverage preparation device mainly uses a water supply pump to draw the external water source into a boiler every time the beverage is prepared, and uses heaters, heat exchangers and other heating equipment to heat the external water source to a set temperature. The hot water is delivered to a liquid dispenser by the circuit system, and the hot water is delivered to a beverage preparation container for the beverage preparation process. [0003] The above-mentioned traditional method of extracting external water source for heating when preparing beverages must make the external cold water be quickly heated into hot...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to maintain a stable water supply temperature, it is necessary to use high-power and high-energy-consuming heating equipment, resulting in waste of energy;

[0005] 2. During the water supply process of the beverage preparation process, it is difficult for hot water to maintain a stable temperature; especially when preparing tea beverages, due to the need to supply a large amount of hot water in a short period of time, the heating equipment is not heated enough to make the supplied heat The temperature of the water is decreasing, which seriously affects the quality and taste of the beverage;

[0006] 3. It takes a period of time for the external cold water to be heated to a set temperature. Therefore, the beverage preparation efficiency of the existing beverage preparation device is poor, and users and customers usually need to wait for a period of time; and

[0007] 4. A complete hot water supply system, including boilers, heaters, heat exchangers, various temperature control components, and water flow control devices such as solenoid valves, flow meters, one-way pressure relief valves, throttle valves, etc. The function can only supply hot water to a single liquid dispenser and beverage preparation container to prepare a single beverage; resulting in a large volume of each beverage preparation device and high equipment costs

[0010] China Taiwan Announcement No. M247802 patent case and commercially available water boilers do not require the supply of hot water to be kept at a stable first temperature setting value, and there is no external automatic hot water supply function at constant temperature, so it is not suitable for applications that require stable temperature Beverage preparation device at hot water temperature
