    • A diffuser is provided on a beverage supply tube (22C) having a beverage supply valve (53). Air bubbles formed in the beverage in the final stage of filtration for extraction are removed from the beverage, and only the gas is passed through the beverage supply tube, whereby the tube is air-blown. Thereafter, the beverage remaining in the diffuser is drained through a drain tube. A pair of electrodes (70) are provided on the beverage supply tube which leads the extracted beverage to the serving cup portion, in order to detect the presence and absence of the beverage based on the conduction caused by the beverage between the electrodes. An air pipe (52) for supplying air to the extraction chamber (20D) from an air pump is provided with a branch, and a pressure sensor for detecting the pressure within the extraction chamber during the filtration is attached to the branch. The on/off duty ratio of the air pump is controlled based on a pressure signal from the pressure sensor, so as to control the pressure within the extraction chamber below a predetermined pressure.
    • 在具有饮料供给阀(53)的饮料供给管(22C)上设置扩散器。 从饮料中除去在过滤提取的最后阶段在饮料中形成的气泡,并且只有气体通过饮料供应管,由此吹管。 此后,残留在扩散器中的饮料通过排水管排出。 在饮料供给管上设置一对电极(70),该饮料供给管将抽出的饮料引导到服务杯部,以便基于由电极之间的饮料引起的传导来检测饮料的存在与否。 用于从空气泵向抽取室(20D)供给空气的空气管(52)设置有分支,并且用于在过滤期间检测提取室内的压力的压力传感器附接到分支。 基于来自压力传感器的压力信号来控制空气泵的开/关占空比,以将提取室内的压力控制在预定压力以下。

    • A bevarage extracting device of a vending machine is disclosed which includes a cylinder (1) into which mixture liquid of hot water and material powder flows through an inlet port (1 a). A valve (2) opens and closes the inlet port (1 a) of the cylinder (1). A pressure device (3) supplies pressurized air into the cylinder (1). A filter block (4) is provided at its upper portion with a filter (5) and is biased downward by a return spring (37). A filter block drive mechanism (34) is operable to move the filter block (4) upward by rotating a vertically rotatable rotary lever (35) upward for closing a lower opening (1 b) of the cylinder. The mixture liquid in the cylinder (1) is forcedly filtered through the filter (4) by an inner pressure in the cylinder, which is generated by supplying the pressurized air into the cylinder (1) while closing the inlet port (1a) of the cylinder (1) by the valve (2) and closing the lower opening (1 b) of the cylinder (1) by the filter (5). A pressing spring mechanism (36) is disposed between the rotary lever (35) of the filter block drive mechanism (34) and the filter block (14). The pressing spring mechanism (36) is operable to bias the filter block (14) upward against a biasing force of the return spring (37) when the rotary lever (35) rotates upward. Thus, a pressing force between the cylinder and the filter block can be appropriate, and breakage of parts can be prevented.
    • 公开了一种自动贩卖机的灭食提取装置,其包括:热水和材料粉末的混合液体流过入口(1a)的气缸(1)。 阀(2)打开和关闭气缸(1)的入口(1a)。 压力装置(3)将加压空气供应到气缸(1)中。 过滤器块(4)在其上部设置有过滤器(5),并通过复位弹簧(37)向下偏置。 过滤块驱动机构(34)可操作以通过向上旋转可旋转的旋转杆(35)向上移动过滤块(4),以封闭气缸的下部开口(1b)。 气缸(1)中的混合液体通过气缸中的内压被强制过滤通过过滤器(4),该压力是通过将压缩空气供给到气缸(1)而同时关闭气缸的入口(1a)而产生的 (2)的气缸(1),并通过过滤器(5)关闭气缸(1)的下部开口(1b)。 在过滤块驱动机构(34)的旋转杆(35)和过滤块(14)之间设置有按压弹簧机构(36)。 当旋转杆(35)向上旋转时,按压弹簧机构(36)可操作以将过滤块(14)向上抵抗复位弹簧(37)的偏置力而向上偏置。 因此,气缸和过滤器块之间的按压力可以是适当的,并且可以防止部件断裂。
