Description

Swirl tray for coffee machines

The present invention relates to a component of a coffee machine, in particular to a swirl type water separator of the coffee machine.

Referring to FIG. 1 , it is an existing coffee machine 9 , which includes a water supply unit 91 suitable for providing brewing water, and a brewing unit 92 detachably mounted on the water supply unit 91 and suitable for holding coffee powder. The water supply unit 91 can provide brewing water with appropriate water temperature, water volume, and even water pressure parameters, so as to extract coffee liquid according to brewing requirements. However, the water supply unit 91 adjusts the parameters of the brewing water through a complex mechanical mechanism. In order to achieve the adjustment function, the coffee machine 9 also needs to be equipped with a complex mechanism, which inevitably results in a large volume and is very inconvenient to use.

Referring to FIG. 2 , another conventional coffee machine includes a water inlet unit 1 suitable for introducing a brewing water from a water source, and a brewing unit 2 connected downstream of the water inlet unit 1 . Wherein, the brewing unit 2 includes a body 21 surrounding and defining an inner space 20, a powder cup 22 arranged in the inner space 20 and suitable for containing coffee powder to be brewed, and a cup connected to the water inlet unit. 1 and is arranged upstream of the powder cup 22, and is used to adjust the water separation module 23 for brewing water according to its own specifications. Referring to Fig. 3 and cooperating with Fig. 2, the water diversion module 23 has a disc body 231 defining a water inlet hole 230, a side fixed to the disc body 231 opposite to the water inlet unit 1 and formed with a perforation 239 A water outlet net 232, and a fixing screw 233 pierced through the through hole 239 and the water inlet hole 230. Wherein, the fixing screw 233 has a water outlet hole 235 . The fixing screw 233 is screwed into the water inlet hole 230 to fix the water outlet net 232 and the disc body 231 . And the water flow derived from the water outlet hole 235 can be introduced into the powder cup 22 through the water outlet net 232 .

However, although the water separation module 23 can lead the water flow through the water outlet net 232, the water outlet net 232 comes out of the water through numerous longitudinally penetrating pores (not shown in the figure), so the water flow that is derived is still unavoidable. There is a form of simple downward dripping, and the coffee powder contained in the powder cup 22 cannot be stirred horizontally, so the water flow caused by brewing only provides a simple downward force without stirring effect, and cannot fully release the coffee flavor. In addition, after the brewing is completed, there is still some brewing water above the powder cup 22 , so when the body is depressurized, the coffee fines brought by the remaining water will seep back into the outlet net 232 . If the pores of the water outlet network 232 are blocked by the coffee fines that have been brewed, in addition to being difficult to clean, when the water distribution module 23 is used for the next brewing, it is also possible that the water outlet network 232 was previously blocked. If the fine powder affects the taste of the brewed coffee, it is bound to need to be improved.

Therefore, the object of the present invention is to provide a vortex water separator for a coffee machine that can provide a uniformly stirred water flow for brewing.

Therefore, the vortex type water tray of the new coffee machine defines a longitudinally extending auxiliary line, and the coffee machine includes an arc-shaped surface with at least one arc-shaped surface that surrounds the auxiliary line with the auxiliary line as the axis, and surrounds the auxiliary line A body wall defining an installation space. The vortex-type water diversion tray of the coffee machine is suitable for installation in the installation space, and includes a bottom wall, and a bottom wall that is bent from the outer periphery of the bottom wall and extends in the same direction, and is co-defined with the bottom wall around the auxiliary line. A surrounding wall of the water-inlet space.

The surrounding wall has a plurality of water outlet holes that pass through the surrounding wall from the water inlet space toward the at least one arc surface of the body wall, and are used to guide a water flow from the water inlet space toward the body wall along a water outlet direction. . Wherein, one extension line of the water outlet direction and the auxiliary line are oblique to each other.

In addition, the vortex-type water diversion tray of the novel coffee machine includes a bottom wall, a surrounding wall bent from the outer peripheral edge of the bottom wall and extending in the same direction, and an active wall set on the outside of the surrounding wall.

An auxiliary line extending longitudinally and passing through the bottom wall is defined, and the surrounding wall surrounds the auxiliary line and jointly defines a water inlet space with the bottom wall, and has a plurality of penetrating through the surrounding walls, and is used to divide a water outlet along a water outlet direction. The outlet hole through which the water flow is directed outward from the water inlet space. Wherein, one extension line of the water outlet direction and the auxiliary line are oblique to each other.

The active wall has at least one arc-shaped surface facing the water outlet holes and surrounding the auxiliary line with the auxiliary line as an axis.

The effect of the present invention is that: the water flow directed toward the body wall along the water outlet direction from each of the water outlet holes will contact the at least one arc-shaped surface of the body wall in a direction deviated from the axis, thereby simultaneously generating a flow around the auxiliary body wall. The circumferential component of the line, or the circumferential component around the auxiliary line due to contacting the at least one arcuate surface of the active wall in a direction deviated from the axis, so that the water flow has already flowed down the auxiliary line In the case of a pressure difference, a swirling water flow can be generated downwards, thereby providing an evenly stirred water flow for brewing coffee.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Fig. 4 and Fig. 5, it is one of the first embodiment of the vortex-type water separator of the new coffee machine, defining a longitudinally extending auxiliary line L, the coffee machine 8 includes a circle around the auxiliary line L as the axis The auxiliary line L is an arc-shaped arc surface S, and surrounds a body wall 81 defining an installation space 80 . This first embodiment is suitable for installation in the installation space 80, and includes a bottom wall 3, and a bottom wall 3 bent from the outer periphery of the bottom wall 3 and extending in the same direction, and surrounding the auxiliary line L and connecting with the bottom wall 3. The surrounding walls 4 jointly define a water-entry space W. Specifically, the body wall 81 is generally in the shape of a ring, and its diameter and width are roughly consistent with the circular shape of the first embodiment. This first embodiment is installed in the coffee machine 8 that brews coffee with a high-pressure water supply mechanism. A water supply device (not shown in the figure) that supplies brewing water with high pressure is arranged upstream, and a suitable water supply device (not shown) is installed downstream. In the powder cup 7 filled with coffee powder, brewing is performed through the water separation effect produced by the first embodiment. However, the mode of water supply or the structure of the powder cup 7 is not the main technical axis of the present invention, so the relevant details will not be described in detail later.

The bottom wall 3 has a bearing surface 31 facing the water inlet space W, and a guiding surface 32 opposite to the bearing surface 31 and having a tapered side away from the water inlet space W. Wherein, considering that the bottom wall 3 needs to withstand the upstream high-pressure water flow, the first embodiment is preferably formed by turning a whole piece of complete metal material to avoid weaker structures in specific areas. Based on the premise that the first embodiment needs to be manufactured from a complete piece of metal material, the carrying surface 31 is flat and perpendicular to the auxiliary line L, which is more conducive to simplifying the manufacturing process.

The surrounding wall 4 has a plurality of water outlet holes 40 penetrating the surrounding wall 4 from the water inlet space W toward the arc surface S of the body wall 81 . Each of the water outlet holes 40 is used for guiding a water flow from the water inlet space W toward the body wall 81 along a water outlet direction D1. Wherein, one of the extension lines of the water outlet direction D1 is skewed with the auxiliary line L as shown in FIG. When hitting this arcuate surface S, reflection along said radial direction does not occur. In the first embodiment, considering the model of the coffee machine 8 and the installation position of the powder cup 7 , the arc-shaped surface S is the inner wall surface of the powder cup 7 .

Referring to Fig. 6 together with Fig. 5, when using the first embodiment to brew coffee, the brewing water introduced into the water inlet space W from the upstream will be exported from the water outlet holes 40 due to high pressure after entering the water inlet space W. . The water flow derived from the water outlet holes 40 is not perpendicular to the tangent direction of the arc-shaped surface S, so it can continue to guide along the arc-shaped surface S to generate a circumferential component around the auxiliary line L. Then, in cooperation with the longitudinal component produced by the high-pressure water flow from top to bottom, after the water flow passes through the first embodiment, it cooperates with the body wall 81 of the coffee machine 8 to form a downward vortex water flow.

Compared to purely downward water flow, the water flow in the form of vortex can produce more rapid stirring of coffee grounds, making the extraction process more uniform and efficient. In this way, in the use of coffee powder, only a small amount of powder is needed to achieve the same extraction effect and the same level of taste. In addition, when the water flow in the form of eddy current is provided to the coffee powder, the coffee powder is stirred more evenly, and in the case that the channel is much larger than that of the coffee powder, the coffee liquid containing part of the fine powder after extraction and pressure release, It is also less likely to block the outlet holes 40 . In this way, in addition to being easier to clean after brewing, there will be no fine powder remaining in each microstructure, and the situation of repeated extraction of old powder will not be caused when brewing next time. The optimal parameters for each brewing It is also relatively controllable, and the taste will not be adversely affected, which really helps the quality of brewing.

Referring to FIG. 7 , which is another implementation of the first embodiment, the bearing surface 31 of the bottom wall 3 is conical in shape protruding toward the water-entry space W. Referring to FIG. In this embodiment, after the water flow is introduced into the water inlet space W, the bearing surface 31 can further form a guiding structure that can guide the water flow to the water outlet holes 40 due to the shape of the bearing surface 31 that is inclined from the center to the surroundings. The water flows toward the water outlet holes 40 faster, and the brewing water is less likely to remain in the water inlet space W after brewing is completed.

Referring to FIG. 8 , it is a second embodiment of the vortex water separator of the new coffee machine. This second embodiment includes a bottom wall 3 and a surrounding wall 4 bent from the outer periphery of the bottom wall 3 and extending in the same direction. , and a set of action wall 5 set on the outside of the surrounding wall 4 . Referring to Fig. 8 and Fig. 9 at the same time, an auxiliary line L extending longitudinally and passing through the bottom wall 3 is defined, and the surrounding wall 4 surrounds the auxiliary line L and jointly defines a water entry space W with the bottom wall 3, and has multiple A water outlet hole 40 penetrates through the surrounding wall 4 and is used to guide a water flow from the water inlet space W outward along a water outlet direction D1 as shown in FIG. 9 . Wherein, an extension line of the water outlet direction D1 and the auxiliary line L are oblique to each other. Specifically, the active wall 5 can be made additionally, and fixed to the bottom wall 3 by means of welding, welding, gluing and the like. The active wall 5 includes a surrounding portion 51 that surrounds the water outlet holes 40 and has an arc-shaped surface S spaced apart from the water outlet holes 40, and a ring that is bent from the bottom end of the surrounding portion 51 and leans against The abutting portion 52 of the bottom wall 3 enables the active wall 5 to be more stably fixed on the bottom wall 3 . The arc-shaped surface S faces the water outlet holes 40 and takes the auxiliary line L as an axis to form an arc around the auxiliary line L. As shown in FIG.

Specifically, compared with the first embodiment, the second embodiment forms the arc-shaped surface S outside the water outlet holes 40 through the active wall 5, so there is no need to cooperate with it as shown in FIG. The body wall 81 of the coffee machine 8 shown can utilize the arc-shaped surface S of the action wall 5, so that the water flow derived from the water outlet holes 40 generates a component that surrounds in the circumferential direction, so as to form a vortex downward. purpose of water flow.

Referring to FIG. 10 , it is another embodiment of the second embodiment. Compared with the embodiment in which the bearing surface 31 of the bottom wall 3 is flat, the bearing surface 31 of the bottom wall 3 can also be Convex toward the water-entry space W. In this way, the effect of making the water flow faster and preventing the brewing water from remaining in the water-inlet space W is exerted.

Referring to Fig. 11 and Fig. 12, it is a third embodiment of the swirl type water separator of the new coffee machine. The difference between the third embodiment and the second embodiment is that the bottom wall 3 of the third embodiment has A bottom ring surface 33 facing the outside in a direction away from the auxiliary line L, a plurality of water guide holes 30 penetrating from the water inlet space W to the bottom ring surface 33, and a direction parallel to the auxiliary line L recessed on the opposite side A groove 39 is provided on one side of the water entry space W. Referring to Fig. 11 to Fig. 13 at the same time, the water guide holes 30 are used to guide a water flow from the water inlet space W outward along a water guide direction D2, an extension line of the water guide direction D2 and the auxiliary line L skewed towards each other. The third embodiment also includes a setting groove 39 disposed on the bottom wall 3, and has an arc facing the water guide holes 30 and surrounding the auxiliary line L with the auxiliary line L as the axis.
