Field of the Invention The present invention is directed to a coffee machine, and more particularly to a coffee machine having a controlled 5 delivery system. L Prior Art 3 Background of the Invention A conventional household coffee machine includes a boiler, an upper container, and a vertical conduit connecting the boiler to the container. When the coffee machine is placed on a 10 heat source, such as a cooker, the temperature and pressure of the boiler will increase. In this case, the conduit can be used to take pressurized water from the lower boiler, passing the pressurized water through a chamber containing the coffee powder (so-called, extraction) step, and then flowing it into the upper sifter. In this way, a coffee drink can be produced. There are no household coffee machines that have been used for many years and are considered to be easy to use, and there is no disadvantage. In fact, it is known that when the coffee machine is heated, and thus produces a coffee drink, it rises. The temperature and pressure of the water in the conduit are not fixed. Specifically, the water starts to rise along the conduit at a low temperature (about 45_55t) and a low pressure (about 〇1_〇2 bar (in the case of a slight difference)). When the amount of water in the boiler is lowered, the same amount of heat is supplied to the cookware, and the I temperature = the faster the increase. ~ 20 The field is increased in temperature, and water vapor is formed in the boiler because: The pressure of the water rising from the water m duct will also increase rapidly. The water passing through the chamber containing the coffee powder will form a high temperature (about 95 rhyme. 〇5 200836682 and high pressure (about 0.5-1.5 bar) state. Finally, when the water in the boiler When lowered to the bottom of the guide, the pipe will be filled with the high temperature (% 丄 (9) ^ vapour supplied in the boiler. 5 I know that the water is below 90-95 ° C. The coffee-alpha non-drinks obtained from ^7 have better and more valuable sensory characteristics than most of the water vapors that are more southerly. In detail, we know When the coffee powder is passed through most of the high-temperature (100-105 ° C) water vapor, it will release the substance with a flat taste, and 10 has a burnt, bitter and astringent taste. These conditions determine the so-called,,, The second step, the step, the extraction, the water pressure and the water temperature change during the extraction, the amount of the coffee powder released in the water will also change. The extraction magic and temperature step depends on the amount of water initially filled in 15, Inject the coffee into the appropriate chamber",, -..nm + illusion tightness and particle size, as well as the type and adjustability of the heat source used to heat the coffee machine. In the domestic coffee machine, the extraction status Quite strong: depending on the user's choice, because (10) first expected.,, t splash? ^ 】 20 SUMMARY OF THE INVENTION The object of the present invention is to design a home coffee machine with a controllable twist and a length of one tenth and one long, which can be used for the loss of the above-mentioned conventional knowledge.

The order of the configuration is represented. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The following "up,, and, down", 4, or "high,", and, "low", or, above, and, and, below, etc., will mean The state of the coffee is in the normal vertical direction. The normal vertical condition is when the coffee machine can be firmly placed on the cookware to prepare the population of 10 #1 population, or When the upper container can accommodate the maximum amount of beverage without dripping. The term coffee machine means the most common use of this device, namely the manufacture of coffee from water and grind (/disintegration). It is also generally known and can be used to make other hot beverages, that is, from at least one liquid raw material and at least one private raw material. For the sake of clarity, the following will be made with reference to the manufacture of coffee 15 . As shown in Fig. 5, the coffee machine according to the present invention is generally indicated by 1. The coffee machine 10 includes a boiler 12, a collection container 14, and the crucible can be used to view the boiler 12 and the collection. The container 14 is placed in a conduit 16 in fluid communication with each other. The conduit 16 is placed in a lower region of the boiler 12 in communication with the upper region of the collection vessel 14. A chamber 18 is formed along the conduit 16 to accommodate the coffee powder to prevent the conduit. The flow continuity of 16 is interrupted. Specifically, the top of the boiler is open and has an opening 20 defined by an edge 22 8 200836682. The boiler is adapted to contain liquid material, especially water. The water level of the liquid material in the different operating configurations in the boiler is indicated by 1. According to a possible embodiment, the collection vessel 14 is screwed to the opening 20 of the boiler 512. The container 14 is adapted to contain a hot beverage, in particular coffee (or liquid). The water level of the beverage in the collection container is represented by L in different operating steps or configurations of the curry machine according to the invention. The container or bowl 24 is adapted to be received in the boiler 12, which is inserted into the opening 20 such that the outer edge 26 of the bowl can be placed 10 in the opening 20 of the boiler 12. The bowl 22 defines the chamber 18. A bottom portion 28 of the collection container 14 is An inner hollow tube 30 extends in the collection vessel. The tube 30 extends in a major longitudinal direction, preferably substantially perpendicular to the normal orientation of the coffee machine. The 15 tube 30 has At least one delivery opening 32 is preferably two or more delivery openings 32. More preferably, the delivery openings are disposed on the side of the tube 30 adjacent to the upper end of the tube. In one embodiment, the other opening 34 is disposed above the tube 30. Preferably, the opening 34 is widened outwardly, so that the first-order portion 36 forms an inner passage 20 38 and an outer passage 40, and the outer passage 40 has a larger diameter than the outer portion 40. The inner passage defines a receiving seat 42. According to a possible embodiment, the seat 42 has at least one recess 44, for example, preferably disposed in two diametrically opposed positions. According to a possible embodiment, a narrow portion 46 is disposed in the tube 40 and disposed below the delivery openings 32. The narrow portion 46 is preferably formed by a truncated cone 9 200836682 shaped portion 48 and a cylindrical portion 50 disposed above the frustoconical portion. The bowl 24 and the tube 30 are arranged and arranged to form the duct 10, which defines a conveying path, so that the water contained in the boiler can be increased after the pressure and temperature in the boil After the wheel is routed, the bowl 24 is ascended 'and thus extractable from the feedstock. (4) The leachate rises along the tube 30 and is collected in the collection vessel 14. The coffee machine 10 further includes a release valve 52 disposed between the boiled water 12 and the outside jade. The release valve 52 is configurable in a closed configuration and in an open operational configuration. The relief valve 52 is convertible from the closed configuration to the open configuration after the boiler 12 has exceeded the threshold for releasing the threshold. Accordingly, the 4 release valve 52 is adapted to maintain the boiler 12 in a sealed closed state when the internal pressure value is lower than the release threshold. In addition, the relief valve 52 is adapted to be placed inside the boiler 12 to maintain fluid communication in the ambient environment when the internal pressure value exceeds the release threshold. The release threshold can vary depending on the size of the coffee machine. The "Hai coffee machine 10 further includes a delivery control valve 54 that is placed along the conduit 16. The delivery control valve 54 is adapted to adopt an open operational configuration and a 20 closed operational configuration. The transfer control valve 54 converts from the open configuration to the closed configuration when the coffee or normal hot beverage in the stroke container 14 has reached a given threshold level L. Preferably, but not necessarily, the condition corresponds to the pressure and flow rate of 200836682 (static and dynamic) before the end of the water in the water, and before the high temperature water vapor passes through the coffee powder. The condition of the condition is such that the delivery control valve 54 is adapted to maintain the conduit 16 in an open state until the coffee level L in the collection container has reached a given threshold. This condition is normal to the condition of the coffee machine. The selection is substantially the case for the pressure and flow rate at which the temperature of the water from the boiled water is still below 90-95 ° C and still in a liquid state. Therefore, the delivery control valve 54 is provided In the so-called coffee flow extraction state, the conduit 16 can be maintained in an open state. Further, the delivery control valve 54 is adapted to close the beverage when the beverage 1 in the collection container 14 has exceeded the threshold water level L. The conduit 16 interrupts the fluid communication between the boil water 12 and the interior of the crucible collection vessel 14. Preferably, the threshold value of the threshold L is defined along the conduit 6 from the boiler 12. The water reaches the temperature (100-105. The delivery control valve 54 can be closed to the conduit 16 prior to changing from a liquid to a gaseous state. The delivery control 15 valve 54 is therefore preferably arranged to interrupt the conduit 16 under an over-extracted state of so-called coffee flow. The factor for observing the process from extraction to over-extraction is a given enthalpy of the water level L of the beverage that has been taken from the collection vessel 14 under consideration of a given initial water level in the boiler 12. It is known that the value of this state is preferably corresponding to the predetermined control threshold of the pressure in the conduit 16 immediately upstream of the control delivery (four). ~ The boiler in the boiled water "value is Corresponding to this control threshold value. When the pressure in the boiler is lower than the boiler door, the flow state can be retained in the extraction step. When the pressure in the boiler is higher than the boiler π 11 200836682 At the time of devaluation, the flow state will result in an overextraction step. According to an embodiment of the invention, the boiler gantry value substantially corresponds to the conversion from the open configuration to the closed configuration at the delivery control valve 54 The value of time is 'less than or equal to The threshold value is released. 5 Referring to the embodiment shown in FIG. 2, a plug body of the delivery control valve 54 is indicated in %, which is accommodated in the duct 16, especially in the tube, and in the narrow Below the portion 46. The plug body 56 is free to move in the conduit 16, particularly in the tube 30, preferably to develop along its longitudinal direction, to move in a lower or open or transport position with an up or closed position, In the upper or closed position, it abuts against the narrow portion 46. According to a possible embodiment, the plug body 56 includes a post portion 58 that passes through the narrow portion 46. Preferably, the post portion 58 extends therefrom. The conduit (6) extends, for example, through the other opening 34. According to a possible embodiment, the post 58 has a lateral dimension such that it can be received in the inner passage % of the opening 34. 15 #考号 6G is a - wide portion indicating the % of the column, for example including at least one spoke 62 that extends in a radial direction beyond the size of the conduit. Preferably, two light bars 62 are provided, for example, Preferably, it is arranged such that the spokes 62 are adapted to be received in the individual recesses 44 of the tube 3 when the coffee machine is at least in an operational configuration. In an embodiment, the post portion 58 is formed to expand beyond the radial dimension of the conduit 16 and extends below to form a cover that is adapted to be disposed on the conduit.

The threshold value of the water level L is selected to be the starting water level of L~~mu, so that the delivery control valve 54 can be used to make the #夏贝on close when the boiler threshold is closed, and the bean is released. Threshold value. Therefore, the low release valve is also closed. Along with the guide 14 200836682 Lu 6 will be interrupted and the pressure in the boiler 12 will continue to increase. Figure 4 illustrates the coffee machine in a fourth operational configuration in which the force in the boiler has reached operating pressure, causing the release valve 52 to open outwardly. The fact that the source, such as the heat supplied to the coffee machine by the cookware, causes an increase in the pressure in the boiler. The pressure in the boiler 12 is higher than the release door interpolation. m i Therefore, the release valve 52 is in a closed state and the transport control 54 is in a closed state. The pressure in the boiler causes the relief valve 52 to open. A flow of water vapor (indicated by the dashed arrow) is generated through the release 1 valve 52 to the external environment and the pressure of the boil is reduced. As those skilled in the art can easily understand from the above, according to the operation of the coffee machine 10 of the present invention, when the water level L of the beverage in the collection container has reached a threshold value, the water can be stopped through the cavity. Room 18. The threshold value of the water level is selected from a given starting value of one of the water levels 1 of the water in the boiler, and 1 corresponds to the normal use of the coffee machine, so as to substantially correspond to a value, here The value 疋 measured by the pressure and temperature in the boiler 12 above the value is judged to be excessive. Accordingly, the coffee machine 1 according to the present invention is preferable in that it can limit the non-drinking product, which can be obtained by low-temperature and low-pressure water, and can prevent water from passing through the coffee powder at an excessive temperature and pressure. The available non-beverages are therefore generally sensory qualities that have been clearly improved. According to the embodiment shown in Figs. 6 to 9, the same elements as those of the above embodiment are denoted by the same reference numerals. Also in this embodiment, the delivery control valve 54 can be adapted to transition from an open configuration to an open configuration when the water level L of the coffee or normal hot beverage in the collection vessel 14 has reached a given threshold. Specifically, the floating body 66 is 15 200836682 3 ==: the wheeled control valve 54 ′ such that the wheeled control valve 54 is 槛 二 from: ::::: exceeds a given door 5 5 according to the sixth In the embodiment shown in FIG. 9, preferably, the cymbal is movably connected to the plug body 5 of the transport control side μ to lift the plug body 56, so that the 隹 乂 举 举 举 产 产 “ “ The water level of the beverage reaches - the given 'm body 56 closes the conduit 16.

In the example shown in the figures, reference numeral 80 refers to Not connected to the nozzle of the distal capsule 70 and the tube 30, and the nozzle 80 defines at least the delivery opening 5 32. The sealing bodies 82 and 84 are respectively disposed between the nozzle 80 and the capsule 70 ' and the nozzle 8G and the Between the conduits 16, and in particular the tube & in an embodiment not illustrated herein, the nozzle 80 and the bladder 70 are also formed in a single piece. Preferably, the bladder 70 has another opening 76a. It is disposed under the distal capsule, for example, it can be inclined with respect to the longitudinal direction of the capsule. In the figure 7A, it is 10 A possible variant embodiment wherein the opening 7 is coaxial with the capsule 7, for example, suitable for low pressure conditions, and a corresponding small size coffee machine. For example, the opening 76a may be adapted to release coffee at the end of the procedure. According to an embodiment, the plug body 56 is spherical. When the float body 66 includes at least one magnet 68, the material of the plug body 56 is adapted to be along the tube due to the magnetic attraction of the magnet 68. 30. The operation of the above embodiment is similar to the embodiment shown in Figures 1 to 5, except that the interaction between the plug and the floating body is performed by magnetic force to attract magnetic attraction. It is better. In particular, Figures 6 and 7 show, ▲ the open configuration of the delivery control valve 54, wherein the plug body 56 is in the lowered position, which corresponds to the lower stop or the lowered position corresponding to the floating body. In addition, Figures 8 and 9 show the closed configuration of the delivery control valve 54, wherein the plug body 56 is in the raised position, which corresponds to the threshold value of the liquid level L in the collection vessel 14. The raised position of the float. 17 200836682 Figures 10 through 17 show another possible embodiment. Specifically, it is a variation of the embodiment shown in Figs. 6 to 9, but is not limited thereto. According to a possible embodiment, the coffee maker 1 includes a selection device 86 for varying the threshold of the liquid level L in the collection container, thereby changing the type of beverage being prepared. Preferably, the selection device 86 permits selection of at least two types of beverages, preferably three beverages. When made into coffee, the selection device allows for a change in the amount of water contained in the beverage, such as an article that provides espresso, standard coffee or light coffee. According to a possible embodiment, the selection means is adapted to change the threshold value of the liquid level L in the collection container by changing the length of movement of the floating body before the delivery control valve 54 is closed. Specifically, the length of movement of the plug body 56 is set to be changeable. More specifically, the position of the narrow portion 46 for the plug body to abut against the delivery control valve is set to be changeable. In the embodiment illustrated in Figures 10-17, the selection device 86 includes the bladder 15 body 7 and the nozzle 80 which is slidably mounted along the conduit 16, particularly in the tube 30. According to a possible embodiment, the movement of the capsule 70 and any of the nozzles 8 is produced by a threading device 88 which includes a button 9 for operation by the user. The distal button 90 is rotatably mounted at the end of the tube 3''''''''''''''''' Preferably, a screw/nut member 96 is provided, wherein a first portion 96a is coupled to the button 90 and a second portion 96b is coupled to the capsule 7 or the nozzle 8A. The thread can also be extended in a single revolution to have a relatively large pitch.

Preferably, the two sliding abutting portions 98 are disposed in the individual grooves 100, for example, in a relative position of the diameter of the tube 3''. The first 〇17 diagram shows several positions of the capsule 70 when the configuration employed by the selection device is applied. Figure 13-17 shows the configuration used to make espresso. The bladder 7 is located at the lowest position relative to the tube 30 whereby the movement of the plug and corresponding float is relatively short. The corresponding threshold value of the water level L is quite low. Figures 10-12 show the configuration used to make the light coffee. The capsule 7 is located at the highest position relative to the tube 3, whereby the movement of the body and the corresponding float is relatively long. The corresponding threshold value of the water level L is quite high. When placed in the intermediate configuration between the above, it corresponds to the configuration used to make the standard coffee. The bladder 70 is located intermediately relative to the tube 30, whereby the movement of the substrate and the corresponding float is relatively moderate. The corresponding threshold value of the water level L is quite moderate. During the operation of the coffee machine described above, the coffee moves along the capsule 70 and the nozzle 80 and flows through the grooves 100 to the collection container. To select among the possible actuation configurations, the user can rotate the button 9 to, for example, cause a notch to a reference mark on the plate 92.
