Claims (3)

  1. A beverage extraction apparatus that extracts beverages in an extraction chamber, A cylindrical cylinder, A filter block is configured to be movable relative to the cylinder and forms the extraction chamber by blocking the opening at the lower end of the cylinder with a filter for filtering the beverage in between, The filter block is provided with a dispensing unit for dispensing the beverage extracted in the extraction chamber, An outlet pipe, one end of which is connected to the discharge section and configured to bend as the filter block moves, and the other end of which is connected to an outlet-side connecting pipe that guides the beverage discharged from the discharge section to the outside of the extraction chamber, The system includes an abnormality detection unit that detects whether the first connection state between the discharge unit and the outlet piping has been released, or whether the second connection state between the outlet-side connecting pipe and the outlet piping has been released. The abnormality detection unit includes a light-emitting unit that emits detection light so as to be blocked by the outlet piping in one of the following states: when the first connection state or the second connection state is released, and when neither the first connection state nor the second connection state is released; and a light-receiving unit that receives the detection light. Beverage extraction equipment.
  2. A filter holding unit that holds the strip-shaped filter as the filter in a retractable manner, A filter feeding unit pulls out and feeds the strip filter from the filter holding unit such that the unused area of the strip filter is sandwiched between the cylinder and the filter block, The system further includes a drop assist unit positioned above the filter feeding unit, which bends the strip-shaped filter fed by the filter feeding unit downwards, thereby causing the residue of the raw materials used in the extraction of the beverage to fall. The aforementioned outlet piping is located below the filter block, The detection light is emitted such that, when the extraction chamber is formed, it is located between the drop assist portion and the filter feeding portion of the strip-shaped filter, passes through the lower side of the non-flexed used area, and is blocked by the discharge piping in the aforementioned state. The abnormality detection unit detects whether the first connection state or the second connection state has been released based on the state of light reception of the detection light at the light receiving unit after the extraction chamber has been formed. The beverage extraction apparatus according to claim 1 .
  3. An extraction unit comprising a cylindrical cylinder, a filter block configured to be movable relative to the cylinder and forming an extraction chamber by sandwiching a strip-shaped filter for filtering beverages between them and closing the opening at the lower end of the cylinder, a discharge unit provided on the filter block for discharging the beverage extracted in the extraction chamber, and an extraction unit including an outlet pipe, one end of which is connected to the discharge unit and configured to bend with the movement of the filter block, and the other end of which is connected to an outlet-side connecting pipe that guides the beverage discharged from the discharge unit to the outside of the extraction chamber, An abnormality detection unit including a light-emitting unit that emits detection light and a light-receiving unit that receives the detection light, such that the detection light is blocked by the outlet pipe in one of the following states: the first connection state between the discharge unit and the outlet pipe, or the second connection state between the outlet-side connecting pipe and the outlet pipe, or the first connection state and the second connection state, or the state in which the first connection state and the second connection state are not released. A determination unit that determines whether or not the detection light is blocked by the aforementioned outlet pipe, The system includes a notification unit that, when the determination unit determines that the detection light has been blocked, notifies that the first connection state or the second connection state has been released. Anomaly detection system.

Description

This disclosure relates to a beverage extraction apparatus, an anomaly detection method, and an anomaly detection system. Conventionally, beverage extraction devices that extract beverages such as coffee through a strip-shaped paper filter are known (see, for example, Patent Document 1). In the beverage extraction device described in Patent Document 1, when extracting a beverage, first, a paper filter is placed between the filter blocks, and the filter block is raised to press it against the lower end of the cylinder. Next, powdered raw materials are introduced into the cylinder, whose bottom is sealed by the paper filter, and then hot water is supplied in multiple stages. Simultaneously with the supply of hot water, a tube pump is operated to pour the filtered extract into a paper cup. Once the extraction of the extract is complete, the filter block is lowered, separating the paper filter from the lower end of the cylinder, and a scraper scrapes off any raw material residue adhering to the inner wall of the cylinder onto the paper filter. Then, the paper filter, wound onto the supply roller, is wound onto the take-up roller, causing the paper filter to move and the raw material residue on the paper filter to be collected in the raw material residue container.
