Description

Technical Field

[0001] This utility model relates to the field of beverage making equipment technology, specifically to a hot water pump for a coffee machine. Background Technology

[0002] As a core piece of equipment in modern coffee culture, the versatility of coffee machines and their ease of operation have always been a focus for both consumers and manufacturers. Among these features, the hot water inlet, often referred to as the hot water nozzle or hot water outlet, is a highly practical component. Having a hot water inlet reduces the need for repeated water heating, allowing users to directly obtain hot water from the inlet instead of activating the entire heating system each time. Secondly, for those who prefer Americano, the hot water inlet provides direct hot water for brewing coffee grounds, offering convenience and speed. Additionally, it can be used for cleaning and maintenance, flushing the interior with hot water to help remove residual coffee grounds and limescale. Currently, an increasing number of coffee machines are equipped with independent hot water inlets.

[0003] However, generally speaking, coffee machines share the same boiler for both the hot water pipe and the steam pipe. This boiler is relatively large, primarily to provide ample steam. During coffee machine use, if the coffee output is not large, the water in the boiler cannot circulate effectively and will be repeatedly heated, creating a situation similar to "repeatedly boiled water," resulting in floating debris in the water. Because existing coffee machines do not have a filtration system, the water is used directly for brewing coffee without filtration. Due to the low water quality, the brewed beverage (such as an Americano) has a poor taste. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

The directional terms used in this invention, such as upper, lower, front, back, left, right, inner, outer, upper surface, lower surface, side, top surface, bottom, front end, rear end, and end, are merely directions in the accompanying drawings and are used only to explain and illustrate this invention, not to limit the scope of protection of this invention.

[0027] In the accompanying drawings, components with identical structures are indicated by the same numerical designation. When some components are described as being "on" another component, the component may be directly placed on the other component; alternatively, an intermediate component may exist, on which the component is placed, and the intermediate component is placed on the other component. When a component is described as being "mounted to" or "connected to" another component, both can be understood as being directly "mounted" or "connected," or as one component being indirectly "mounted to" or "connected to" another component via an intermediate component.

[0028] As described in the background section, most coffee machines are currently equipped with a hot water pump and a steam wand to froth milk and brew coffee. Furthermore, the hot water pump and steam wand typically share the same boiler. This boiler is relatively large, primarily to provide ample steam. During coffee machine use, if the coffee output is not large, the water in the boiler cannot circulate effectively and will be repeatedly heated, creating a situation similar to "repeatedly boiled water." This leads to an increased mineral concentration in the water and may cause floating debris to appear, affecting the user experience.

[0029] To solve this technical problem, this utility model provides a novel hot water rod for coffee machines, which can effectively remove scale from the water and reduce the mineral concentration in the water.

[0030] like Figure 1 As shown in the figure, an embodiment of the present invention provides a hot water pipe for a coffee machine, including a hot water pipe 100. The inlet end of the hot water pipe 100 is connected to the coffee machine and communicates with the hot water system inside the coffee machine; the outlet end of the hot water pipe 100 is connected to a filter element 200. In a preferred embodiment, the hot water pipe 100 consists of an outer pipe and an inner pipe, wherein the outer pipe is fitted over the inner pipe, and the space between the inner and outer pipes is filled with heat-insulating material, thereby providing heat insulation and preventing the surface temperature of the hot water pipe 100 from rising rapidly and causing burns to the skin.

[0031] Please see Figure 2-3 In this utility model, the filter element 200 includes a disc filter 210, a filter screen 220, and an annular pressing plate 230; wherein, the bottom wall of the disc filter 210 is provided with a plurality of filter holes 211; the filter screen 220 is disposed on the disc filter 210, the middle part of which protrudes upward to form a dome shape, and its periphery is pressed into the disc filter 210 by the annular pressing plate 230.

[0032] In this invention, by setting a filter screen 220 and a disc filter 210 in the filter element 200, the incoming water can be filtered twice, thereby effectively removing scale from the water.

[0033] If the filter screen 220 is a flat filter screen 220, when placed on the disc filter 210, the filter screen 220 will adhere to the bottom wall of the disc filter 210, causing some of the mesh openings in the filter screen 220 to be blocked, thus affecting the filtration efficiency. In this invention, the middle part of the filter screen 220 is raised upward to form a dome shape, so that the filter screen 220 does not contact the bottom wall of the disc filter 210, thereby avoiding the blocking of some of the mesh openings in the filter screen 220 and improving the filtration efficiency.

[0034] In this invention, the filter screen 220 is made of a material with high safety and high temperature resistance, preferably a filter screen 220 made of 304 stainless steel or Tritan material.

[0035] In some embodiments of this utility model, the bottom wall of the disc filter 210 is slightly convex upward to form an arched portion 212, and a plurality of filter holes 211 are evenly distributed around the arched portion 212. This design makes the bottom wall of the disc filter 210 high in the middle and low around the edges. Therefore, when water flows into the disc filter 210, it will preferentially flow towards the area around the arched portion 212 and be quickly filtered out by the filter holes 211 arranged around the arched portion 212.

[0036] In this invention, the coffee machine hot water rod also includes a cylindrical water distributor 300. Please refer to [link / reference needed]. Figure 4-5 The cylindrical water distributor 300 has openings at both the top and bottom. A disc filter 210 is fitted into the top opening of the cylindrical water distributor 300. An adsorption block 330 is provided at the bottom opening of the cylindrical water distributor 300 to seal it. The adsorption block 330 has a porous structure, which can adsorb impurities in the water, thereby further purifying the water. Preferably, the adsorption block 330 is detachably installed on the cylindrical water distributor 300, so that after a period of use, when the porous structure on its surface becomes clogged, it can be removed and replaced with a new adsorption block 330.

[0037] In this invention, a plurality of water distribution ports 310 are provided on the inner wall of the cylindrical water distributor 300, and the plurality of water distribution ports 310 are evenly distributed circumferentially on the inner wall of the cylindrical water distributor 300. Water entering the cylindrical water distributor 300 can be evenly discharged through the plurality of water distribution ports 310.

[0038] In some embodiments of this utility model, an annular baffle 340 extends inward from the lower opening of the cylindrical water distributor 300, and the adsorption block 330 is supported on the annular baffle 340. Furthermore, a plurality of elastic clips 320 for fixing the adsorption block 330 are formed on the inner wall of the cylindrical water distributor 300, and the plurality of elastic clips 320 are preferably arranged at the water outlet 310. Through the elastic clips 320, the adsorption block 330 can be stably fixed at the lower opening of the cylindrical water distributor 300, and is easy to disassemble.

[0039] Further, please see Figure 1 and Figure 6 The hot water pump of this invention also includes an outer shell 130, which is fitted onto the outside of the water distributor; and an annular outlet 350 for hot water to flow out is provided between the inner wall of the outer shell 130 and the outer wall of the water distributor. This results in more even water distribution and better brewing of coffee and other beverages.

[0040] Furthermore, the hot water rod of this invention also includes a ball-end connector 120 and a tail connector 110. The first end of the ball-end connector 120 is connected to the outlet end of the hot water pipe 100, and the second end of the ball-end connector 120 is connected to the outer casing 130. The tail connector 110 is used to connect to the coffee machine body. The outer casing 130 can be connected to the ball-end connector 120 in various ways, such as by snap-fit ​​or threaded connection.

[0041] In summary, the hot water stick for coffee machines provided by this utility model has an internal filter device that can effectively filter the water, improve the water quality, and enhance the taste of brewed beverages.

[0042] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
