Description

Technical Field

[0001] This invention relates to the water tank of a coffee machine, specifically a water tank with a handle for a coffee machine. Background Technology

[0002] A coffee machine is an electrical appliance used for making coffee. It is generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines require manual operation for grinding, tamping, filling, brewing, and cleaning up coffee grounds. Fully automatic coffee machines are fully automated, controlling the entire coffee brewing process from preheating and cleaning to grinding, tamping, brewing, and dispensing. They brew coffee according to scientific data and procedures, requiring only a simple press of a button. Both types of coffee machines require a water tank, typically located at the rear of the machine. Examples include Chinese patent application number 202322561961.7, authorized on May 7, 2024, entitled "A Coffee Machine Water Tank"; and application number 202322123913.X, authorized on March 15, 2024, entitled "A Coffee Machine Handle Water Tank Assembly". The aforementioned structure and similar products generally use an integrated handle and bucket opening, or use the lid as a handle; however, water tanks with this structure often have some inconveniences in terms of extraction and operation. On the one hand, the connection between the water tank and the handle is not secure enough, and it may loosen or even fall off during extraction, affecting safety and convenience. On the other hand, the existing extraction device design is not user-friendly enough, and it is relatively laborious to operate, failing to meet users' needs for convenience; furthermore, it lacks a filter element structure design, and its stability after installation is poor, making it prone to shaking. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a coffee machine with a handle and water tank, thereby solving the technical problems of inconvenient extraction and installation, poor stability, inconvenient production and use, and poor accuracy of liquid level detection caused by the suboptimal structural design of existing similar products. This objective is achieved through the following technical solution.

[0004] A coffee machine with a water tank and a handle is provided. The top opening of the water tank has a lid, and a handle bracket is snapped and fixed in the middle of the inner diameter of the top opening of the tank below the lid. The handle bracket is integrated with the tank body, and a one-way valve is provided at the water outlet at the bottom of the tank body. The tank body and lid are rectangular prisms. The handle bracket has a rectangular inner hole in the middle and is a rectangular frame. A handle is provided in the inner diameter of the rectangular inner hole of the handle bracket. The key structural design features a U-shaped arch in the middle of the handle. The inner diameter of one side of the lid has symmetrically raised connecting plates that protrude above the lid opening. The two ends of the handle are respectively hinged and fixed to the shaft holes at both ends of the rectangular inner hole in the middle of the handle bracket. At the same time, the cylinder of the connecting plate at the lid is inserted into the column holes at the two corners of the handle bracket through two symmetrically arranged notches on one side of the top opening of the tank body. Therefore, once the lid, handle, and handle bracket are assembled as a single unit, they can be inserted into the box body via the handle bracket, making production and assembly relatively convenient. At the same time, once the handle and handle bracket are assembled in advance, they can be used as universal parts, allowing for the assembly of different lids as needed.

[0005] The handle has a raised retaining rib at the top of its central arch, and symmetrically positioned retaining ribs on the inner diameter of the rectangular inner hole of the handle bracket. When the handle rotates and retracts into the rectangular inner hole of the handle bracket, the retaining ribs of the handle and the handle are abutted and limited, and the top of the handle retracts flush into the rectangular inner hole of the handle bracket. This allows the handle to rotate 180° within the handle bracket, providing gripping options from different angles; furthermore, the handle will not fall into the water below when not in use.

[0006] The lid is hinged to the top of the box opening via a connecting plate, creating a 100° vertical opening angle.

[0007] The hinged ends of the handle and handle bracket are parallel or perpendicular to the hinged ends of the lid. Since the box body and lid are rectangular, it is preferable that the handle and lid are parallel in the opening direction.

[0008] The one-way valve is located at the bottom center outlet of the box below the handle bracket. Above the one-way valve, there is a raised, equidistant, circular filter element column on the outside of the bottom center outlet of the box. One end of the water filter base is snapped to the filter element column of the box. The other end of the water filter base is snapped to the cover of the top cover of the water filter. A filter element is installed inside the water filter base.

[0009] The top of the water filter cover has a top rod at one end, and the end of the top rod has a head larger than its diameter. The top cover, top rod, and head are integrally injection molded. The head of the top cover is located in the middle of the rectangular inner hole of the handle bracket inside the housing. The inner circumferential surface of the top cover has raised grid ribs that interference-fit the filter element. This facilitates the removal and replacement of the filter element through the head of the top cover, and allows for its replacement after it has been fixed inside the top cover, without the need to drain the water from the housing before replacing the filter element.

[0010] The bottom of the tank has a recessed groove that opens towards the installation side. A downward-protruding central column sleeve is located on the bottom boss of the one-way valve in the center of the bottom groove. The height of the central column sleeve is lower than the three circumferential edges of the bottom groove. Below the handle bracket mounting position on the installation side of the tank, there is an installation groove integrally connected to the bottom groove. The width of the bottom boss where it connects to the installation groove is smaller than the width of the installation groove. The installation groove has a longitudinally protruding arc-shaped edge from top to bottom, the height of which is less than the depth of the installation groove. Thus, when the central column sleeve at the bottom of the tank is inserted into the rear water inlet of the unit, the bottom groove, groove surface, installation groove, and bottom boss of the tank are respectively installed corresponding to the protrusion and groove on the installation side of the unit, preventing the water tank from shaking.

[0011] The bottom groove of the tank has guide ribs on both sides of the opening, and positioning ribs are symmetrically arranged on the inner walls of both sides of the bottom groove. This further improves the groove and positioning fit at the corresponding positions, making the water tank more stable.

[0012] The depth of the top cover of the recessed surface of the tank body is less than the depth of the bottom recess at the other end, which is integrally connected. This further improves the stability of the water tank, meaning that the tank is more stable when the corresponding grooves are fitted together under its own weight.

[0013] A liquid level sensor is installed on the inner wall of one bottom side of the housing. The liquid level sensor is fixed to a fixing groove on the inner wall of the bottom side of the housing by a fixing plug. A Hall switch sensor is installed on the corresponding part of the housing. Therefore, when the water level is lower than the liquid level sensor, the water in the housing is disconnected from the liquid level sensor, and the liquid level sensor triggers the Hall switch sensor on the housing to issue a water filling command.

[0014] This invention features a reasonable structural design, making overall production, disassembly, and cleaning convenient. It exhibits good stability after installation, facilitates filter replacement, and has a versatile handle bracket with a handle. It also provides accurate detection of the liquid level critical point, making it particularly suitable for production and use. It is well-suited for use as a water tank with a handle in coffee machines, and can also be used for structural improvements to similar products. Attached Figure Description

The bottom of the housing has a bottom groove 803 opening towards the installation side. A downward-protruding intermediate sleeve 804 is provided on the bottom boss at the one-way valve in the middle of the bottom groove. The height of the intermediate sleeve is lower than the circumferential edges of the bottom groove on three sides. A mounting groove 806, integrally connected to the bottom groove, is provided below the handle bracket mounting position in the middle of the groove surface 805 on the installation side of the housing. The width of the bottom boss where it is integrally connected to the mounting groove is smaller than the width of the mounting groove. An arc-shaped edge 807 protrudes longitudinally from top to bottom in the middle of the mounting groove, and the height of the arc-shaped edge is less than the depth of the mounting groove. Guide ribs 8031 ​​are provided on both sides of the opening end of the bottom groove, and positioning ribs 8032 are symmetrically provided on the inner walls of both sides of the bottom groove. The depth of the top cover end of the groove surface is less than the depth of the bottom groove integrally connected at the other end.
