Hot-water brewing mechanism and system with low power and abundant water supply

Abstract

The invention provides a hot-water brewing mechanism with low power and abundant water supply, comprising a boiler, a first pressure detector, a second pressure detector, a water-level probe, a water inlet unit and at least one water supply unit, wherein the first pressure detector, the second pressure detector and the water-level probe are arranged on the boiler body, the water inlet unit is connected to the boiler, and the at least one water supply unit is connected from the boiler; the boiler comprises the boiler body and a heater, the vapor pressure in the boiler body can be controlled within a stable range through the first pressure detector and the second pressure detector, and the boiler can be used for reserving preheated hot water for using in the abundant water use. As the hot water is not synchronously heated by utilizing a large-power heater, not only the electric power consumption at the peak time can be reduced, but also a great amount of water can be loaded. The invention also provides a hot-water brewing system with low power and abundant water supply, comprising the brewing mechanism and a control module.

Description

technical field [0001] The invention relates to a brewing hot water supply mechanism for brewing coffee, tea or other beverages, especially a hot water brewing mechanism with low power and large amount of water supply. The invention also relates to a brewing system for brewing coffee, tea or other beverages. Background technique [0002] The brewing mechanism is used in the brewing system for brewing espresso, tea or other beverages. In response to the characteristics of various coffees or teas, there are various brewing systems designed to provide different temperatures of heat. Water is used for brewing required beverages. [0003] The heating device of the brewing mechanism (such as an espresso machine) in the prior art needs to be continuously heated to supply the required amount of water during the working process. The disadvantage is that the power of the heating device is limited when the peak sales time increases with the increase of water consumption. However, it ...

AI Technical Summary

Problems solved by technology

[0006] In the brewing mechanism using the prior art, when the brewing mechanism is in the brewing state, the brewing mechanism will input cold water into the heat exchanger 130 and indirectly pass through the hot water in the heating tank of the heating device 120 for heating, but due to The capacity of the heat exchanger 130 is limited and the power of the heating device 120 can only heat a fixed amount of hot water to the desired temperature per unit time, for example, only 30 liters of cold water can be heated to 95°C per hour. If the hot water at 95°C exceeds 30 liters per hour, the brewing mechanism in the prior art will not be able to load the total water consumption during the peak hours, resulting in the inability to supply hot water at the required temperature in real time or the problem of unstable outlet water temperature

However, if the electric power of the heating device 120 is increased, there will be problems of cost burden, energy consumption and difficulty in obtaining high-power power supply in general beverage stores.

[0007] In addition, the brewing mechanism of the prior art will have a cup warming tray on the top that can conduct the heat emitted by the boiler, thereby raising the temperature of the container in advance, so as to avoid the brewed beverage from being damaged due to the low temperature of the container. However, warming the cup and tray will cause the heat of the brewing mechanism to be lost to the environment, which will not only cause energy waste, but also cause environmental thermal energy pollution
