Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and more particularly to a brewing unit and coffee machine with a convenient disassembly and assembly of a throttling block. Background Technology

[0002] A coffee machine is a device used to make coffee, which mainly includes an extraction device, a water tank, a heating element, a water pump, and a brewing unit.

[0003] Chinese patent CN209107002U discloses a coffee brewing apparatus and coffee machine, including a first brewing head, a second brewing head, and a closed chamber. The first brewing head includes a first cylinder, a first mounting body, a bowl component, and a water outlet pipe. A throttling block is provided in the water outlet pipe, and a throttling orifice is provided on the throttling block to create a certain pressure in the closed chamber, so that the coffee can be fully brewed in the closed chamber.

[0004] The throttling orifice on the throttling block in the above structure can limit the flow rate of coffee from the closed chamber. Since the throttling orifice is mostly set to be small, it is easy to get clogged during the use of the coffee machine. Since the throttling block with the throttling orifice is set in the water outlet pipe, if you want to clean the throttling orifice on the throttling block, you need to disassemble the brewing device, which makes it more troublesome to clean the residue and other substances that are blocked on the throttling orifice. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies where the throttling block is installed inside the water outlet pipe, requiring disassembly and reassembly of the brewing device to clean the throttling port, resulting in the cumbersome process of cleaning residue clogging the throttling port. It provides a brewing unit and coffee machine with a throttling block that is easy to disassemble and assemble.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A brewing unit with a convenient throttling block includes a brewing unit body. The brewing unit body includes an inlet connected to a hot water source, an outlet for water discharge, and a brewing unit. A water flow channel is provided between the outlet and the brewing unit to guide the hot water flowing from the outlet to the brewing unit. A throttling block is provided on the water flow channel to limit the water flow rate. A plug-in groove is provided on the brewing unit body, and the throttling block is plugged into the plug-in groove.

[0008] Using the above scheme, the throttling block can be inserted into the insertion slot provided on the brewing unit body. When the throttling block becomes blocked in the process of limiting the water flow, it can be pulled out of the insertion slot for cleaning. After cleaning, the throttling block can be inserted back into the insertion slot, which makes it convenient for the operator to clean the throttling block when it becomes blocked.

[0009] Preferably, the throttling block extends partially outside the brewing unit body, and a pulling component is formed at the point where the throttling block extends outside the brewing unit body to facilitate the operator to pull the throttling block.

[0010] Preferably, the pulling component includes a pulling groove provided at the point where the throttling block extends out of the brewing unit body, which facilitates the operator in pulling the throttling block.

[0011] Using the above scheme, the pull groove provided at the point where the throttling block extends out of the brewing unit body makes it easy for the operator to pull the throttling block out of the insertion groove or insert the throttling block into the insertion groove.

[0012] Preferably, the water flow channel includes an inlet channel that leads hot water vertically upward and an outlet channel that leads hot water vertically downward. A reversing structure is provided at the end of the inlet channel and the outlet channel away from the brewing unit to redirect the hot water in the inlet channel into the outlet channel.

[0013] Preferably, the reversing structure includes a reversing block, which has an inlet channel connected to the inlet channel, an outlet channel connected to the outlet channel, and a connecting channel for connecting the inlet and outlet channels located away from the brewing unit body.

[0014] By adopting the above scheme, the inlet and outlet water channels can be connected through the connecting channel, thereby changing the flow direction of water within the brewing unit.

[0015] Preferably, the insertion slot is located at the connection channel.

[0016] Preferably, the throttling block includes a throttling orifice with a size smaller than the inlet channel that is directly opposite to the inlet channel after being inserted into the plug slot, and a clearance orifice with a size greater than or equal to the outlet channel that is directly opposite to the outlet channel after being inserted into the plug slot. An opening and closing component for opening and closing the throttling orifice is provided on the side of the reversing block near the connecting channel.

[0017] The above scheme allows the throttling orifice to restrict the water flow from the inlet channel, thus making the coffee brewing more thorough. The clearance orifice guides the water flowing out of the throttling orifice to the outlet channel when the opening and closing component opens the throttling orifice. The opening and closing component controls the opening or closing of the throttling orifice.

[0018] Preferably, the opening and closing component includes an opening and closing valve for opening and closing the throttling orifice, which is disposed on one side of the reversing block near the connecting flow channel.

[0019] Using the above scheme, the opening and closing valve can control the opening or closing of the throttling orifice. When the opening and closing valve controls the throttling orifice to open, coffee can be brewed; when the opening and closing valve controls the throttling orifice to close, water flow can be prevented from flowing to the brewing unit.

[0020] A coffee machine includes a coffee machine body, the coffee machine body including the brewing unit with the aforementioned easy-to-disassemble throttling block.

[0021] By adopting the above solution, the brewing unit with a removable throttling block installed in the coffee machine body can facilitate the operator to insert and remove the throttling block set in the brewing unit body, making it easier for the operator to clean the throttling block when it becomes clogged.

[0022] This utility model has significant technical effects due to the adoption of the above technical solutions: the plug slot provided on the brewing unit body allows the throttling block to be inserted. When the throttling block becomes blocked in the process of restricting the water flow, it can be pulled out of the plug slot for cleaning. After cleaning, the throttling block can be inserted back into the plug slot, which makes it convenient for the operator to clean the throttling block when it becomes blocked.
