Hot water supply head for coffee extractor {Group head for coffee extractor}

The present invention relates to a hot water supply head for a coffee extractor. More specifically, the ring frame that connects and supports the fixture that ejects hot water and the portafilter is dualized, and the coupling angle of these ring frames is adjusted according to the situation. By allowing the mounting direction of the portafilter to be variable, the portafilter can be mounted in the desired direction without any special restrictions, even if the housing of the coffee extractor is placed in various directions to suit the space situation or a housing with a unique design that fits the interior concept is applied. It is possible to set and use the coffee extractor, and furthermore, it is possible to arrange the coffee extractor more efficiently in a limited occupied space and to place it more harmoniously in the interior. In addition, the coffee extractor itself can be adjusted by incorporating a unique arrangement direction and design that fits the interior. This relates to a hot water supply head for a coffee extractor that can be used as an interior element.

As the number of people who love coffee and tea increases, and coffee shops in particular explode in number, many people enjoy coffee, etc., and the demand to enjoy the optimal taste of coffee by preserving the deep taste and aroma of coffee is also increasing.

In order to drink coffee or tea, water is heated and the hot water is poured or brewed into the coffee or tea. In particular, coffee beans are drunk in the form of espresso, in which coffee is extracted in a short period of time by spraying high-temperature hot water at high pressure on ground coffee beans. Alternatively, espresso can be mixed with hot water or milk to suit various tastes.

Accordingly, a coffee extractor is used as a machine for extracting coffee beans. A coffee extractor generally includes a heater device that heats and pressurizes water and supplies it to the coffee extraction head, and a supply device that supplies hot water heated from the heater device to the coffee extraction head. It is equipped with a conduit and a discharge conduit returning from the coffee extraction head, and has a valve mounted on the head that functions to supply or block hot water to the coffee extraction head. The coffee is extracted based on the temperature of the thermometer mounted on the heater device. Coffee is extracted after recognizing that it has been heated to an appropriate temperature for extraction.

This type of coffee extractor has a structure in which a portafilter loaded with coffee beans is combined with the head to extract espresso using hot water provided from the head.

On the other hand, as shown in FIGS. 1 and 2, a typical coffee extractor is arranged so that the head 1 is exposed to the outside at the front of the box-shaped housing 3, and operates hot water toward the head 1. Various hot water operating system configurations, for example, the hot water supply means (2), have a structure built into the housing (3). At this time, considering design convenience and connection efficiency between each component, a heater device, supply conduit, discharge conduit, The hot water supply means (2) including the valve configuration has a structure in which the head (1) is installed in a row forward and backward.

Accordingly, the front-to-back width of the housing 3 had to become longer, so not only did the design of the housing 3, which is in charge of the exterior of the coffee extractor, become monotonous and uniform, but also the space utilization had to be significantly reduced due to the long front-to-back structure.

In addition, once the coffee extractor is installed on site, it is not easy to move and install it in a different direction where work flow can be improved because water supply, sewerage and piping work are done, and in particular, the portafilter (4) of the head (1) is not easy. Since it is only connected in one fixed direction, the arrangement of the coffee extractor has to be fixed in a direction that takes into account the worker's work flow and convenience, and in some cases, the coffee extractor itself becomes very incongruent with the interior of the room. there is.

In order to fully understand the present invention, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Prior to describing the present invention, the following specific structural and functional descriptions are merely illustrative for the purpose of explaining embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention may be modified and implemented in various forms. and the scope of the present invention should not be construed as being limited to the embodiments described in detail below.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments will be illustrated in the drawings and described in detail in this specification.

However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and should be understood to include changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

This example is provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description.

It should be noted that identical members in each drawing may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

The hot water supply head 1 (hereinafter referred to as head 1) for a coffee extractor according to the present invention is a main part of the coffee extractor that supplies hot water to the mounted portafilter 4, and is largely comprised of the fixture 10. , it can be defined as including a ring frame 30 and a fixing means 40.

The fixture 10 is configured to supply hot water supplied from the hot water supply means 2 toward the portafilter 4. A coffee extractor usually has a hot water supply means 2 built into the housing 3. , Due to the structure in which the head 1 is mounted on the outside of the housing 3, the fixture 10 can be fixedly installed in the housing 3, and its installation location is not particularly limited.

At this time, the head 1 according to the present invention is implemented in a completely dual configuration in which the ring frame 30 that connects and couples the portafilter 4 to the fixture 10 of a fixed configuration is completely divided from each other. The mounting direction of the portafilter 4 can be adjusted as needed by attaching or detaching the ring frame 30 from the stagnant 10 or adjusting the coupling direction of the ring frame 30 itself.

That is, the conventional head (1) has an integrated, single configuration, so the direction of coupling of the portafilter (4) cannot be adjusted, and the portafilter (4) is installed only in a single, uniform direction following a fixed installation position. did.

In other words, since the conventional coffee extractor has a structure in which the mounting direction of the portafilter (4) is determined depending on the arrangement direction of the housing (3), the head (1) is installed so that it is placed in the front of the coffee extractor for the operator's convenience in operation. Since the head (1) and the hot water supply means (2) formed in a row from it must be arranged long back and forth, the coffee extractor itself becomes enlarged front and back.

These enlarged coffee extractors generally have uniform and monotonous exterior designs that not only do not blend in harmoniously with specialized interiors, but also, in some cases, interfere with workers' work movements.

On the other hand, the head 1 according to the present invention has a ring frame 30 that substantially connects and supports the fixture 10 that ejects hot water and the portafilter 4, and depending on the situation, these ring frames ( 30) can be adjusted to change the mounting direction of the portafilter (4), so even if the housing (3) is placed in various directions to suit the space situation, or a housing (3) with a unique design that fits the interior concept is applied, a special It is possible to set the mounting direction of the portafilter (4) in the desired direction without restrictions.

For example, in a conventional coffee extractor, as shown in FIGS. 1 and 2, the housing 3 itself had to be arranged long back and forth in order to set the mounting direction of the portafilter 4 to the front, whereas the head according to the present invention In a coffee extractor with (1) applied, even if the housing (3) is arranged in various directions to suit the space situation, the mounting direction of the portafilter (4) can be adjusted to suit convenience, allowing the coffee extractor to be placed more efficiently in a limited occupied space. It can be placed more harmoniously in the interior, and the coffee extractor itself can be used as an interior element by combining a unique arrangement direction and housing (3) design that matches the interior.

First, the fixture 10 is fixedly installed in the coffee extractor and includes a spout 12 for spouting hot water to the inside, a hot water supply passage 13 for supplying hot water, a hot water discharge passage 15 for discharging hot water, and hot water from the inside. It is provided with a circulation pipe (13) that circulates and a reservoir (18) that stores hot water.

More specifically, in the center of the fixture 10, a cylindrical ejection basin 11 is formed to protrude downward for a certain length, and the ejection outlet 12 is formed open at the lower surface of the ejection basin 11 to form the ejection basin 11. It should be equipped with a structure that ejects hot water from the bottom.

At this time, although not shown, a diffuser is coupled to the lower surface of the outlet 11 to uniformly supply hot water ejected through the outlet 12 onto the portafilter 4.

The spout 12 may be exemplified as a hot water movement pipe provided inside the fixture 10.

A circulation pipe 13 is formed inside the fixture 10, and a hot water supply passage 13 is formed at one end of the circulation pipe 13, and a hot water discharge passage 15 is formed at the other end, respectively, forming the circulation pipe 13. , the hot water supply path 13 and the hot water discharge path 15 form one channel connected to each other.

The hot water supply path 13 and the hot water discharge path 15 extend parallel to each other toward the rear of the fixture 10 and are opened at the rear of the fixture 10, and the open hot water supply path 13 and the hot water The supply pipe 16 and the discharge pipe 17 may be connected and installed in the discharge passage 15.

The fixture 10 has a substantially cylindrical shape and is made of a metallic material so that it has strength and durability that does not deform or contaminate even in high temperature and high pressure hot water.

The circulation pipe 13 is a hot water movement passage formed inside the fixture 10. A hot water supply passage 13 is formed at one end of the circulation pipe 13, and a hot water discharge passage is at the other end of the circulation pipe 13. While (15) is extended, a supply pipe 16 through which heated hot water is supplied is connected to the hot water supply passage 13, and the hot water discharge passage 15 exits the circulation pipe 13 and returns toward the heater. A discharge pipe 17 through which hot water moves may be connected.

Meanwhile, the heater part is a detailed configuration of the hot water supply means (2), and is in the form of a closed water tank. Water is stored inside and a heater is installed to heat the water as the heater heats, and the hot water is distributed through the supply pipe. It can be supplied to the fixture 10 through (16). At this time, a heat exchanger is connected to the heater inside the water tank of the heater unit and can be used to generate hot water, and the pressure tank supplies high temperature hot water inside the water tank through the supply pipe (16). ) is used to smoothly supply to the fixture (10).

That is, the supply pipe 16 is a pipe that supplies hot water from the heater unit to the fixture 10, while the discharge pipe 17 is the hot water that circulates and is discharged from the fixture 10, that is, it is not used for coffee extraction but is circulated. This is the pipe through which the hot water that comes out returns to the heater.

Known technologies generally used in coffee extraction machines may be applied to the heater.

According to this structure, the hot water supplied from the heater unit can be introduced into the interior of the fixture 10 through the supply pipe 16, flow in the circulation pipe 13, and then return to the heater unit through the discharge pipe 17. there is.

Hot water is supplied to the fixture 10 through the supply pipe 16, but if coffee is not extracted, the hot water supplied to the fixture 10 does not reach the outlet 12 but is returned to the heater through the discharge pipe 17. At this time, whether the supplied hot water is discharged through the spout 12 or circulated through the discharge pipe 17 can be controlled by the valve 5, which will be described later.

A reservoir 18 may be provided on the inner upper portion of the fixture 10.

The reservoir 18 is a space formed inside the upper part of the fixture 10, and some of the hot water in the circulation pipe 13 flows in, while the hot water stored in the reservoir 18 flows through the outlet 12 according to the operation of the valve 5. ) and can be ejected into the portafilter (4).

At this time, the circulation pipe 13 has a structure surrounding the reservoir 18, so that the optimal high temperature for extracting coffee can be maintained without heat loss of hot water even during coffee extraction.

Since the hot water flowing around the circulation pipe 13 must be drawn to the reservoir 18, the extraction path 19 may be branched from one side of the circulation pipe 13 and connected to the reservoir 18.

That is, the hot water in the circulation pipe 13 can be supplied to the reservoir 18 through the extraction furnace 19 and stored.

For example, hot water formed at a temperature optimized for coffee extraction is supplied from the heater unit through the supply pipe 16 to the fixture 10, and in the process of going around the circulation pipe 13 and exiting the discharge pipe 17, the hot water is extracted. It can flow into the reservoir (18) through (19).

The reservoir 18 may be wide at the top and narrow toward the bottom, and the open top can be opened and closed with a separate cap.

Meanwhile, a valve connection passage 20 and a high pressure injection passage 21 may be formed in the fixture 10. At this time, a venturi pipe 18a is provided between the bottom of the reservoir 18 and the valve connection passage 20. It is provided so that the reservoir (18) and the valve connection path (20) can be interconnected.

In addition, the valve (5) functions to control the supply and blocking of hot water. At this time, the valve connection pipe (6) is installed between the valve connection passage (20) and the valve (5), and the high pressure injection passage (21) A high-pressure injection pipe (7) is installed between the valve and the valve (5), so that the hot water in the valve connection passage (20) can selectively flow to the high-pressure injection passage (21) according to the opening of the valve (5). is equipped.

At this time, the high-pressure injection furnace (21) is connected to the outlet (12) to form a single channel. When the valve (5) is opened, hot water can be directed to the outlet (12) through the high-pressure injection furnace (21). And when the valve (5) is closed, hot water remains partially charged in the reservoir (18).

Meanwhile, in the circulation pipe 13, a bypass passage 22 is branched toward the outside of the fixture 10, and hot water in the circulation pipe 13 is discharged to the outside of the fixture 10 through the bypass passage 22. make it possible

The open end of the bypass passage (22) can be opened and closed with a separate cover or combined with a hot water dispenser to discharge hot water from the circulation pipe (13) as needed so that it can be used in the right place.

Since hot water heated to a certain temperature flows through the circulation pipe 13, the hot water discharged through the bypass passage 22 can be widely used for purposes other than hot water for extracting coffee.

If the structure of the above-described fixture 10 is organized according to the flow of hot water, the hot water entering the fixture 10 through the supply pipe 16 circulates along the circulation pipe 13, and at this time, the reservoir 18 After passing adjacent to one side, it is discharged into the discharge pipe (17).

Meanwhile, some of the hot water circulating in the circulation pipe 13 flows into the reservoir 18 through the extraction furnace 19, and the rest is discharged through the discharge pipe 17.

At this time, if the valve (5) is in an open state, the hot water introduced into the reservoir (18) sequentially passes through the venturi pipe (18a), the valve connection pipe (20), and the valve connection pipe (6) and then passes through the high pressure injection pipe (7). ), can be supplied to the jet nozzle 12 through the high pressure injection furnace 21 and injected into the portafilter 4.

On the other hand, if the valve (5) is blocked, the flow of hot water in the reservoir (18) is blocked through the valve connection pipe (6), and in this state, no additional hot water is introduced through the extraction furnace (19). The hot water circulating in the circulation pipe (13) is discharged as is through the discharge pipe (17).

Meanwhile, the hot water used for coffee extraction is first used as hot water stored in the reservoir 18, and the reservoir 18 is always maintained at a high temperature by the high-temperature hot water circulating through the circulation pipe 13, so the reservoir 18 is maintained at a high temperature at all times. The hot water stored in the burr 18 can also be used for coffee extraction in a hot state while maintaining the high temperature heated in the heater unit.

Meanwhile, in a conventional coffee extractor, when the valve (5) is closed, heated hot water returns to the heater from the inlet of the head (1), so while coffee is not being extracted, the head (1) continues to cool and is heated for coffee extraction. When high-temperature hot water is supplied, a significant amount of heat is consumed to warm the cooled head (1), so there is a problem in that the taste and aroma of the coffee cannot be preserved as hot water at a lower temperature is used during coffee extraction.

However, in the head 1 of the present invention, the hot water entering the head 1 through the supply pipe 16 surrounds the reservoir 18 and flows inside the fixture 10 along a U-shaped passage connected to the discharge pipe 17. Since it moves circularly through the machine, it is possible to always warm the fixture (10) to the same temperature as the heated water in the heater unit even during normal times when coffee is not extracted, and also stores and discharges the hot water used for actual coffee extraction. Since the circulation pipe 13 circulates around the reservoir 18, the hot water stored in the reservoir 18 can also maintain a high temperature, so the high temperature hot water can be used as is when extracting coffee.

When coffee is not extracted, an electrical signal is not applied to the valve (5), so the valve (5) is in a blocked state. Therefore, the hot water introduced from the circulation pipe (13) to the reservoir (18) is directed to the outlet (12). The stored state is maintained in the reservoir (18), and hot water is circulated in the circulation pipe (13), while this circulated hot water is discharged through the bypass passage (22) and used for purposes other than coffee production. possible.

In the conventional invention, a heater is installed in the head (1) to prevent a decrease in the temperature of the hot water used for coffee extraction in the head (1), and a thermometer is installed in the heater and the head (1) to detect if the temperatures are different. A function to increase the temperature of hot water for coffee extraction has been introduced by operating the heater installed on the head (1) to increase the temperature of the head (1). However, it is difficult to suddenly increase the temperature of the head (1), and it is difficult to increase the temperature of the head (1) quickly. There was a problem in that the hot water passing through the head (1), which had cooled down, did not heat up even if it was cooled, and the structure of the head (1) was complicated and the cost of the device increased, making it uneconomical and unsightly in appearance.

In contrast, in the present invention, there is no need to install a heater, thermometer, etc. in the head (1), and the circulating hot water flows into the head (1) to maintain the head (1) at a high temperature, and at the same time, the hot water stored in the reservoir (18) is kept at a high temperature. By applying structural characteristics that allow high-temperature hot water to be used for coffee extraction through the shortest distance in the circulation pipe (13), hot water used for coffee extraction in the head (1) is used without any additional devices. It has the characteristic of being able to be used at the same temperature as heated in the heater unit.

Therefore, the user sets the temperature controller (not shown) and thermometer (not shown) installed on the heater to the temperature optimized for extraction of the coffee according to the type of coffee he or she wants to drink, and generates hot water at the optimized temperature. Since the head (1) is used to extract coffee at the optimized temperature, it has the characteristic of enjoying the best taste and aroma.

Next, the ring frame 30 is a structure completely unrelated to hot water extraction and simply performs the function of coupling and maintaining the portafilter 4 below the fixture 10.

The ring frame 30 can be detachably provided on the fixture 10, and various types of ring frames 30 that meet the specifications of the portafilter 4 can be alternatively coupled to the fixture 10. Portafilters (4) of various specifications can be used universally.

The ring frame 30 is rotatably coupled to the lower part of the fixture 10, is fixed in position at a specific angle, and detachably supports the portafilter 4 at the bottom, allowing the portafilter 4 to be mounted according to the installation angle. The direction can be changed.

In other words, the portafilter 4 is mounted in only one fixed direction of the ring frame 30, and the installation angle of this ring frame 30 with respect to the fixture 10 is adjusted to ultimately install the portafilter 4. It is a structure that changes the mounting direction.

The ring frame 30 may be largely illustrated as including a cylinder 31, a flange 32, and a support jaw 34.

The cylinder 31, flange 32, and support jaw 34 integrally form the ring frame 30, and the element names are different depending on the formation position.

For example, the cylinder 31 constitutes the center of the ring frame 30 and has a hollow cylindrical structure with an empty interior.

The upper end of the cylinder 31 may be in contact with the fixture 10, and the lower end may be in contact with the portafilter 4.

Inside the cylinder 31, the tempered coffee beans on the portafilter 4 and the spout 11 of the fixture 10 can be accommodated in contact with each other.

The flange 32 is composed of a plate surface extending inward from the upper edge of the cylinder 31 to be parallel to the lower surface of the fixture 10, and the blower 11 passes through the center of the flange 32. A passing hole 33 is formed so that the flange 32 and the blower 11 can be arranged in a concentric circle.

In other words, the flange 32 is complementary to the outside of the spout 11, and accordingly, the ring frame 30 can be adjusted to rotate in place based on the spout 11. It becomes a possible structure.

At this time, the diameter of the through hole 33 is the same as or larger than the diameter of the ejection basin 11 so that the ring frame 30 can be coupled to the ejection basin 11 through a loose fit.

Meanwhile, in the fixture 10, a plurality of first fastening holes 23 are formed at equal intervals along the circumferential direction at a point eccentric at a certain distance outward with the blower 11 at the center, and the flange 32 ) may have a structure in which second fastening holes 36 are formed through each corresponding position facing the first fastening hole 23.

At this time, the first fastening hole 23 may be formed of a female screw structure with a thread, while the fixing means 40 is a configuration that couples and fixes the ring frame 30 to the fixture 10, and is exemplified by a normal bolt. , the first fastening hole 23 and the second fastening hole 36 that are in communication with each other can be passed through each other and fastened and fixed on the first fastening hole 23 by screwing.

When the fixing means 40 fixes the ring frame 30 on the fixture 10, arbitrary rotation of the ring frame 30 may be restricted.

The support jaw 34 is a jaw structure that maintains the portafilter 4 accommodated inside the cylinder 31. It extends from the bottom edge of the cylinder 31 toward the center of the cylinder 31 and is segmented at a certain section to reach the segment point. (35) allows the coupling protrusion (4b) of the portafilter (4) to pass in the vertical direction.

A typical portafilter (4) consists of a bowl-shaped body (4a) that holds coffee beans and a handle (4c) that extends long from the body (4a). At this time, the segment point (35) is located at the upper edge of the body (4a). ) The coupling protrusion 4b may be formed to protrude to a size large enough to pass through.

When positioning the body (4a) of the portafilter (4) below the ring frame (30) for coffee extraction, the body (4a) is aligned with the cylinder (31) with the engaging protrusion (4b) aligned with the segment point (35). After being accommodated inside, the engaging protrusion (4b) of the portafilter (4) introduced into the cylinder (31) is rotated at a certain angle so that it is placed in the corresponding position of the support jaw (34), and the support jaw (34) is engaged. Separation can be limited by supporting the protrusion 4b from the lower part. Additionally, disassembly of the portafilter 4 can be accomplished by performing the above process in reverse.

Therefore, when the ring frame 30 itself, which has the above-described coupling relationship with the portafilter 4, is rotated at a certain angle, the phase of the support jaw 34 changes and follows this to change the coupling direction of the portafilter 4 in various ways. can be adjusted.

The embodiments of the present invention described above are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached patent claims. In addition, the present invention should be understood to include all modifications, equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims.
