Description

Coffee dripper {COFFEE DRIPPER}

The present invention relates to a coffee dripper, and more specifically, to a coffee dripper used by a user to extract coffee using a hand drip method.

The drip coffee production method is the most common coffee production method in the coffee world, and the coffee drippers used to produce this drip coffee can be divided into automatic and manual types.

A manual coffee dripper refers to a coffee dripper used to extract coffee using the hand drip method. Generally, a paper filter (filter paper) is placed in the inner space of the coffee dripper, and then ground roasted coffee beans (coffee bean powder) are placed in the coffee dripper. It is a coffee maker in which the user pours hot water slowly and evenly using a kettle, etc., and the ground coffee beans come into contact with the hot water, and then filter it through a filter to extract liquid coffee.

These manual coffee drippers or hand drip type coffee drippers vary greatly in the taste and aroma of the coffee extracted depending on the method or time of pouring hot water.

However, in the conventional hand drip type coffee dripper, the coffee outlet that discharges the drip coffee filtered by the filter to the outside is always open, so the user has to wait for the time the ground coffee beans are in contact with hot water. Since it cannot be adjusted, there are limitations in extracting coffee that suits the user's taste or preference.

In addition, the conventional hand drip type coffee dripper has a problem in that it is difficult to hold and move the coffee dripper during the process of extracting coffee. For example, coffee extracted using a coffee dripper is dripped into a cup, etc., and in order to drink coffee in a cup, the coffee dripper placed on the cup must be moved. In the process of moving the coffee dripper, a small amount of remaining coffee flows out. It can stain the table or floor, so it is inconvenient to have to support a plate or hand mop.

Referring to FIGS. 2 to 6 , the switch 140 is a means provided to enable the user to easily and conveniently press the lever operating portion 135, which is the other end of the closure operating lever 130. In this embodiment, the switch 140 is disposed on the handle 150 and is coupled to the handle 150 so that the user can intuitively operate it while holding the handle 150. However, differently from this, in the present invention, the switch configuration may be disposed in a part other than the handle portion 150 (for example, the outer surface of the dripper body 110).

Specifically, the switch 140 includes an operation panel 141, a leaf spring 143, and a sliding block 145, as shown in FIGS. 2 to 6.

The operation panel 141 may be provided in a disk shape as shown in FIG. 2 and is disposed above the switch coupling portion 155 of the handle portion 150. The operation panel 141 may be pulled in the outer radial direction of the dripper body 110 in a sliding manner by holding it with the user's fingers (especially the thumb) while holding the handle portion 150.

As shown in FIG. 2, the leaf spring 143 is disposed between the lever operation part 135 of the stopper operation lever 130 and the switch coupling part 155 of the handle part 150 to drip the operation panel 141. It provides an elastic force that pushes the main body 110 in the inner radial direction. Due to the elastic force of the leaf spring 143, the stopper operating lever 130 maintains the arrangement shown in FIG. 3, and accordingly, the stopper 120 is connected to the coffee outlet (coffee outlet) formed on the inner bottom surface of the dripper body 110. 115) remains closed. That is, the switch 140 is provided with an elastic force to maintain the arrangement state (disposition state of FIG. 3) of the stopper operation lever 130 in which the stopper 120 is closed with respect to the coffee outlet 115. Meanwhile, a spring seating portion 155a on which the leaf spring 143 is seated is recessed on the upper surface of the switch coupling portion 155 of the handle portion 150, as shown in FIG.

The sliding block 145 is coupled to the operation panel 141 while disposed below the switch coupling portion 155 of the handle portion 150. The sliding block 145 is a configuration for coupling the operation panel 141 to the switch combination 115, and at the same time, when the operation panel 141 is pulled and pushed in the radial direction of the dripper body 110, the operation panel 141 It is a configuration that guides the sliding movement of ). For this purpose, a pair of coupling protrusions 145a as shown in FIG. 5 are formed on both inner ends of the sliding block 145, and a pair of coupling protrusions 145a of the sliding block 145 are formed on the lower surface of the operation panel 141. A pair of coupling grooves 141a coupled to (145a) are formed, and also at both ends of the upper surface of the switch coupling portion 155 of the handle portion 150, as shown in FIG. 5, a sliding movement of the switch 140 is formed. A pair of guide rail portions 155b for guidance are formed. For reference, a spring contact portion 141b that contacts the leaf spring 143 is formed on the lower surface of the operation panel 141, as shown in FIG. 6.

Meanwhile, in order to provide a clicking or operating feeling to the user when sliding the switch 140, a stepped portion 145c as shown in FIG. 5 is formed on the inner surface of the sliding block 145, and the handle portion 150 ) A pair of stepped grooves 155c spaced apart from each other as shown in FIG. 6 may be formed on the lower surface of the switch coupling portion 155.

The switch 140 according to the present embodiment having the above configuration is operated in a sliding manner. When the user grabs the operation panel 141 of the switch 140 and pulls it in a sliding manner, the lever operation portion of the stopper operation lever 130 is operated. (135) is pressed down, and the lever operating part 131 of the stopper operation lever 130 is lifted by the principle of a lever, thereby opening the stopper 120. That is, this embodiment is a method or structure in which the linear movement of the switch 140 is converted into the vertical movement of the lever operating portion 131 of the stopper operating lever 130.

However, in the present invention, if the switch configuration can exert the function of pressing down the lever operating part 135 of the stopper operating lever 130, it can be used not only in the sliding method of this embodiment but also in various other methods or structures, including the button method. Of course, it can be implemented.

Hereinafter, with reference to FIGS. 7 to 11, a coffee dripper according to another embodiment of the present invention will be described focusing on differences from the above-described embodiment.

The coffee dripper according to this embodiment differs from the coffee dripper according to the above-described embodiment in terms of the stopper and the lever for operating the stopper, and other components are substantially the same as the above-described embodiment, so the same reference numerals refer to the same components. given, and the description thereof shall apply mutatis mutandis to the above-described embodiment.

Figures 7 and 8 are perspective views of the stopper of a coffee dripper according to another embodiment of the present invention, viewed from the top and bottom, respectively, and Figure 9 shows the stopper of Figures 7 and 8 coupled with one end of the lever for operating the stopper. This is a floor plan showing.

Referring to Figures 7 to 9, the stopper 220 according to the present embodiment is disposed at the lower part of the stopper body 221, where one end of the stopper operation lever 230 is coupled, and the stopper body 221. A stopper packing part 223 that opens and closes the outlet 115, and a stopper guide part 225 that guides the stopper 220 to move linearly in the up and down direction according to the operation or movement of one end of the stopper operation lever 230. Includes.

The stopper body portion 221 is a part that provides the overall frame of the stopper 220 and is coupled to the lever operating part 231 that forms one end of the stopper operating lever 230. At this time, the stopper body 221 of the stopper 220 and the lever operating part 231 of the stopper operating lever 230 are coupled in a sliding structure. For this purpose, as shown in Figures 7 and 9, the stopper body A sliding protrusion 221a is formed on the upper part of the part 221, and a sliding groove 231a that engages with the sliding protrusion 221a of the stopper body 221 is formed in the form of a slit at the center of the plane of the lever operating part 231. is formed That is, the lever operating part 231, which is one end of the lever 230 for operating the stopper, is positioned against the stopper body 221 so as not to interfere with the linear movement of the stopper 220 in the vertical direction by the stopper guide part 225. It is combined so that it can be slid. In addition, as shown in FIG. 9, the sliding protrusion 221a has an upper end wider than the gap between the sliding grooves 231a (i.e., has an approximately 'T' cross-sectional shape), so the lever for operating the stopper When the lever operating portion 231, which is one end of 230, is lifted or lowered, it can maintain stable engagement without being separated from the sliding groove 231a.

The stopper packing part 223 is disposed at the lower part of the stopper body 221 and is a part that opens and closes the coffee outlet 115, and is made of a material with a certain degree of elasticity such as silicone to ensure watertightness. That is, the stopper body 221 and the stopper packing part 223 are made of different materials. In particular, the stopper packing portion 223 is formed in a concave structure in which the central portion of the lower surface directly contacting the coffee outlet 115 side is concavely depressed as shown in FIG. 8 to improve watertightness.

The stopper guide part 225 is a part that guides the stopper 220 to move linearly in the up and down direction according to the operation of the lever operating part 231, which is one end of the stopper operating lever 230, and is shown in Figures 7 and 8. As shown, four rail groove structures are provided at each corner of the stopper body 221. However, in the present invention, the number and structure of the stopper guide parts are not limited to this embodiment and may be changed appropriately.

Specifically, the stopper guide portion 225 provided in a rail groove structure at each corner of the stopper body 211 moves the stopper 220 according to the operation of the lever operating part 231, which is one end of the stopper operation lever 230. In guiding it to move linearly in the vertical direction, at least one of the plurality of spaced ribs 111 (four in this embodiment) formed on the inner surface of the dripper body 110 to extend in the vertical direction, as shown in FIG. 9 ) and guides the stopper 220 to move linearly in the vertical direction along the spacing ribs 111.

For reference, the plurality of spacing ribs 111 partially separate the filter F, which is seated in the inner space of the dripper body 110, from the inner surface of the dripper body 110, as described in the above-described embodiment. This is designed to prevent the filter (F) from sticking to the inner surface of the dripper body 110 due to hot water during hand dripping, resulting in poor coffee extraction.

Figures 10 and 11 are cross-sections of corresponding parts to explain the operating principle of the stopper and the lever for operating the stopper in the coffee dripper according to this embodiment. Figure 10 shows the state in which the stopper is closed and the coffee outlet is closed. , Figure 11 shows a state in which the stopper is opened and the coffee outlet is opened.

The lever 230 for operating the stopper of the coffee dripper 200 according to the present embodiment differs only in the lever operating portion 231 forming one end thereof, and other configurations and operating principles are different from those of the coffee dripper 200 according to the above-described embodiment. It is substantially the same as the lever 130 for operating the stopper of the dripper 100. That is, the lever 230 for operating the closure of the coffee dripper 200 according to the present embodiment is also provided as an elongated plate-shaped member and has a structure bent in at least two parts, and the other lever of the lever 230 for operating the closure is provided. When the lever operating part (not shown) forming the end is pressed down (in the downward direction), the lever operating part 231 forming one end of the stopper operating lever 230 is pushed upward (in the upward direction) according to the 'lever principle'. ) is lifted. At this time, the lever operation unit (not shown) is operated using a sliding switch 140 (see FIGS. 3 and 4), similar to the above-described embodiment.

However, unlike the above-described embodiment, the lever 230 for operating the stopper of the coffee dripper 200 according to the present embodiment is not fixedly coupled by inserting the stopper 220 into the lever operating part 231 forming one end thereof. , As described above, it has a structure that is slidably coupled to the stopper 220, and the lever operating part 231, which is one end of the stopper operation lever 230, is lifted upward (in the upward direction) by operating the switch 140. During the raising process, the lever operating part 231 slides relative to the stopper 220, as shown in FIGS. 10 and 11.

The stopper 220 of the coffee dripper 200 according to the present embodiment is operated when the stopper operating lever 130 is operated by operating the switch 140 in the coffee dripper 100 according to the above-described embodiment. ) is moved integrally with the lever operating part 131, which is one end of the lever 130 for operating the stopper, as shown in Figures 10 and 11, it moves linearly in the vertical direction by the stopper guide part 225 I do it.

Here, the stopper guide part 225 provided in a rail groove structure at each corner of the stopper body 211 moves the stopper 220 according to the operation of the lever operating part 231, which is one end of the stopper operating lever 230. In guiding straight movement in the vertical direction, a plurality of spaced ribs 111 formed on the inner surface of the dripper body 110 to extend in the vertical direction are utilized like rails. And, so that the linear movement of the stopper 220 in the vertical direction by the stopper guide part 225 is smoothly implemented without interference, the lever operating part 231, which is one end of the stopper operating lever 230, is connected to the stopper body part. It is slidably coupled to (221). Meanwhile, in order to further improve watertightness, a packing member 115a having a ring band shape and made of a material such as silicon is inserted into the coffee outlet 115 of the dripper main body 110, as shown in FIGS. 10 and 11. do.

For reference, the stopper 120 of the coffee dripper 100 according to the above-described embodiment is fixedly coupled to the lever operating part 131, which is one end of the stopper operation lever 130, so that it curves and moves in the up and down direction as if drawing an arc. In this case, the stopper 120 closes the coffee outlet 115 at an angle and does not completely block the coffee outlet 115, which may cause the coffee inside the dripper body 110 to unintentionally flow out.
