Description

Water diversion net dish of coffee machine

Technical Field

The utility model relates to a component of a coffee machine, in particular to a water diversion net dish of a coffee machine.

Background

Referring to fig. 1, a conventional portable coffee maker includes a body unit 1, and an air pressure unit 2 detachably coupled to the body unit 1. The body unit 1 comprises a carrier 11, a container 12 erected on the carrier 11 and defining a brewing space 120 suitable for containing coffee powder, a water inlet module 13 arranged above the container 12 and defining an inner space 130, a water mixing tray 14 covering the water inlet module 13, and a water containing kettle 15 detachably combined with the carrier 11 to position the container 12, the water inlet module 13 and the water mixing tray 14.

Referring to fig. 1 to 3 together, the container 12 has a bottom plate 121 formed with a plurality of drip holes 129 communicating with the brewing space 120 and through which only water can pass. The water inlet module 13 has a surrounding wall 131 surrounding and defining a through hole 139, a mesh sheet 132 formed with a plurality of fine holes 138 and fixed to the surrounding wall 131 to close the through hole 139, a hole sheet 133 formed with a plurality of water distribution holes 137 having a larger diameter than the fine holes 138 and fixed to the surrounding wall 131 to cover the mesh sheet 132, and a positioning ring 134 disposed at the bottom end of the surrounding wall 131 to position the mesh sheet 132 and the hole sheet 133. The water adjusting plate 14 is covered on the water inlet module 13, and has a plate cover 141 formed with a penetrating water inlet hole 140, and an adjusting member 142 disposed on the water inlet hole 140 and adapted to adjust the flow of water passing through the water inlet hole 140. The water container 15 defines a water containing space 150 communicating with the inner space 120 through the water inlet hole 140, and has an air inlet 159 communicating between the water containing space 150 and the outside. The air pressure unit 2 is connected to the air inlet 159, and is configured to provide high-pressure air from the air inlet 159 to the water containing space 150, and when the water containing space 150 contains hot water in advance, the air pressure unit can supply water with appropriate pressure and flow rate to the brewing space 120 by adjusting the water diversion plate 14 and distributing and guiding water flow into the brewing space 120 by the water inlet module 13, so as to fulfill the requirement of brewing coffee.

The water inlet module 13 is mainly responsible for guiding the water flow into the brewing space 120 in a proper form with a proper hole distribution configuration, because the relatively upstream of the water inlet module 13 is the water flow guided by the high pressure through the water inlet hole 140, and thus the structural strength of the water inlet module 13 is necessary to withstand the high pressure water flow. In the case where the fine holes 138 must be formed to distribute water, in consideration of process difficulty, the fine holes 138 are formed in the thin mesh plate 132, and the entire structure is reinforced by the orifice plate 133, so that the surrounding wall 131, the mesh plate 132, the orifice plate 133, and the positioning ring 134 are formed in a multi-piece structure, and the components are fixed to each other by welding.

However, the process of welding the components to one another using multiple pieces, while meeting the need to form the apertures 138 and the overall structural strength sufficient to withstand the high pressure water flow, is difficult to avoid creating uncleanable gaps between the components. Particularly, after the water flow is introduced into the brewing space 120 from the water inlet module 13, the situation that the coffee powder absorbs water and expands, the water flow seeps back and the like is inevitable, so that the coffee liquid and even the coffee powder which do not pass through the drip hole 129 reversely pass through the fine holes 138 and further infiltrate into gaps between the components. Under the condition that the back-seeped coffee liquid and coffee fine powder cannot be completely removed, the situation that water flow is blocked, the coffee is excessively brewed and the like can be caused under the long-term use, the normal coffee brewing and the taste are influenced, and the doubtful question on the use sanitation can be generated.

Disclosure of Invention

An object of the utility model is to provide a under the prerequisite that is enough to bear high-pressure rivers and distribute rivers, compromise easily abluent demand simultaneously and ensure to use the water diversion mesh ware of sanitary coffee machine.

The utility model discloses the net ware of dividing of coffee machine is applicable to and accepts the leading-in high-pressure rivers from the upper reaches, and makes high-pressure rivers divide and lead to the low reaches and steep coffee. The water distribution mesh dish of the coffee machine comprises a base plate and a peripheral wall, wherein the base plate is provided with a plurality of water distribution holes which are in a penetrating shape, the peripheral wall integrally bends and extends from the periphery of the base plate, and the peripheral wall and the base plate define an inner space with an opening together. Wherein the thickness of the substrate is 2 to 3 millimeters, and the aperture of each water diversion hole is 0.10 to 0.15 millimeter.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 4, an embodiment of the water diversion net of the coffee maker of the present invention is adapted to receive a high pressure water flow introduced from the upstream, and to divert the high pressure water flow to the downstream component for brewing coffee. The embodiment includes a circular substrate 2 having a plurality of water distribution holes 200, and a peripheral wall 3 integrally bent and extended from the periphery of the substrate 2 and defining an inner space 300 having an opening 301 together with the substrate 2.

The thickness of the substrate 2 is 2 to 3 mm, preferably 2 mm. The aperture of each water diversion hole 200 is 0.10-0.15 mm, and the purpose of adjusting water flow can be achieved according to different brewing parameters by selecting specification products with different aperture parameters. The water distribution holes 200 are radially distributed with the center of the base plate 2 as a reference point, and the water flow can be uniformly distributed downwards from the water distribution holes 200 under the condition that an upstream air pressure source is introduced downwards from the right above the center of the circle. In addition, in order to make the substrate 2 have a certain thickness and sufficient structural strength, the water diversion holes 200 are formed by a fiber laser punching process, so that the water diversion holes 200 are formed to penetrate the substrate 2 and uniformly distribute to allow water to pass through.

Referring to fig. 4 and 5, in particular, the present embodiment is used by being fixed to a body 4 defining a high pressure space 400, and having a powder cup 5 disposed relatively downstream for holding coffee powder. When coffee is brewed, a certain amount of water is contained in the inner space 300 in advance, and under the condition that high pressure is provided for the high-pressure space 400 through the air pressure unit 6 capable of providing high-pressure air, the water flow can uniformly pass through the water diversion holes 200 and then drops into the powder cup 5, so that the purpose of brewing coffee is achieved. In the process, because the present embodiment is an integrally formed one-piece design, backflow of coffee liquid and fines during brewing is inevitable and does not clog the gaps between the components as in the prior art. Therefore, the embodiment is easy to clean after use, and under the condition that no coffee liquid and coffee fine powder are left, the coffee fine powder can be repeatedly extracted without coffee liquid in next use, the expected quality of coffee extraction is maintained, and the sanitary condition of use can be ensured.
