Description
饮料冲煮机构及其自动调温装置 技术领域 Beverage brewing mechanism and its automatic temperature regulating device
本发明涉及一种饮料冲煮机构及其自动调温装置, 属于机械领域, 特别是指一种可供制 备不同种类饮料的自动调温式饮料冲煮机构及其自动调温装置。 The invention relates to a beverage brewing mechanism and an automatic temperature regulating device thereof, belonging to the field of machinery, in particular to an automatic temperature regulating beverage brewing mechanism and an automatic temperature regulating device thereof for preparing different kinds of beverages.
说 Say
背景技术 Background technique
饮料冲煮机构被运用于制备咖啡、 茶品或其它饮品。 如图 12 所示的现有的饮料冲煮机 构, 主要是利用一供水泵浦 80供应外界水源至一锅炉 81内, 该锅炉 81设有一加热器 82及 一温度侦测器 83, 用以将该锅炉 81 内的储水加热至书一设定温度范围内; 进行饮料萃取程序 时, 由使用者操作控制一冲煮电磁阀 84开启, 使该锅炉 81内的热水经一出水管 85及一洒水 头 86, 洒入一预置有饮品材料的饮料过滤筒 87内, 浸出的饮料最后流入至一储存桶 88内储 存。 Beverage brewing mechanisms are used to prepare coffee, tea or other beverages. The existing beverage brewing mechanism shown in FIG. 12 mainly uses a water supply pump 80 to supply an external water source to a boiler 81. The boiler 81 is provided with a heater 82 and a temperature detector 83 for The water stored in the boiler 81 is heated to a set temperature range of the book; when the beverage extraction process is performed, the user operates to control the brewing solenoid valve 84 to open, so that the hot water in the boiler 81 passes through an outlet pipe 85 and A sprinkling head 86 is sprinkled into a beverage filter cartridge 87 preset with a beverage material, and the leached beverage finally flows into a storage tank 88 for storage.
上述现有的饮料冲煮机构将锅炉 81内的热水直接供应至洒水头 86出水, 连续使用热水 时, 热水温度随冲煮时间而递减, 当温度侦测器 83侦测锅炉 81内水温低于设定值时, 再行 启动加热器 82加热; 因此, 在进行饮料冲煮程序的连续出水过程中, 热水温度呈现出递减后 陡增再递减的变化曲线, 无法保持于均温状态, 其将影响饮料的冲煮质量, 难以冲煮出最佳 风味的饮料制品, 这是现有的饮料冲煮机构的最大技术问题。 The above-mentioned existing beverage brewing mechanism directly supplies the hot water in the boiler 81 to the sprinkler head 86. When the hot water is continuously used, the hot water temperature decreases with the brewing time, and the temperature detector 83 detects the inside of the boiler 81. When the water temperature is lower than the set value, the heater 82 is further heated; therefore, during the continuous water discharge process of the beverage brewing process, the hot water temperature exhibits a decreasing curve which is sharply increased and then decreased, and cannot be maintained at the temperature uniformity. The state, which will affect the brewing quality of the beverage, makes it difficult to brew the best flavored beverage product, which is the biggest technical problem of the existing beverage brewing mechanism.
现有的饮料冲煮机构尚存在有下列待解决的技术问题: The existing beverage brewing institutions still have the following technical problems to be solved:
1. 由于其热水出水温度仅在一狭窄的温度范围内, 且不同种类的饮料其最佳冲煮温度并 不相同, 因此现有的饮料冲煮机构一般仅供冲煮单一种类的饮料, 对于有冲煮不同种类饮料 (例如红茶及绿茶等)需求的使用者, 造成极大的不便; 1. Because the hot water outlet temperature is only in a narrow temperature range, and the optimal brewing temperature of different types of beverages is not the same, the existing beverage brewing mechanism is generally only for brewing a single type of beverage. It is extremely inconvenient for users who have the need to brew different types of beverages (such as black tea and green tea).
2. 为配合饮料的冲煮温度, 该锅炉 81 内储水的加热温度范围较小, 仅能略高于饮料冲 煮温度; 当连续出水时, 经常发生储水温度低于冲煮温度的情形, 此时即需等待加热器 82将 储水加热至略高于冲煮温度, 才能恢复饮料冲煮程序, 致使现有的饮料冲煮机构的工作效率 不佳; 2. In order to match the brewing temperature of the beverage, the heating temperature range of the water stored in the boiler 81 is small, and can only be slightly higher than the brewing temperature of the beverage; when the water is continuously discharged, the storage temperature is often lower than the brewing temperature. At this time, it is necessary to wait for the heater 82 to heat the stored water to a temperature slightly higher than the brewing temperature, so as to restore the beverage brewing procedure, resulting in poor work efficiency of the existing beverage brewing mechanism;
3. 进行冲煮时, 热水由该洒水头 86 的多个出水孔, 以水流方式洒出, 致使放置于该饮 料过滤筒 87内的饮品材料难以均匀地与热水接触, 导致饮料的冲煮质量因受水不均而变差;
以及 3. When brewing, the hot water is sprinkled by the water outlet of the sprinkler head 86, so that the beverage material placed in the beverage filter cartridge 87 is difficult to uniformly contact with the hot water, resulting in the flushing of the beverage. The quality of the cooking is deteriorated due to uneven water; as well as
4. 进行冲煮时, 是以出水时间计算出水量, 不但难以精确计算完成冲煮后的饮料容积, 而且因饮料容积不固定的因素, 相对影响饮料的冲煮质量。 发明内容 4. When brewing, the amount of water is calculated based on the water discharge time. It is difficult to accurately calculate the volume of the beverage after brewing, and the brewing quality of the beverage is relatively affected by the fact that the volume of the beverage is not fixed.
