Description

Field of Invention

The present invention relates to a microwave oven, and more particularly, to a microwave oven having a coffee maker provided in a predetermined chamber space of this electronic device.

State of the art

A microwave oven is a device for defrosting and heating food under the influence of microwave radiation. Figure 1 shows a known microwave in an exploded perspective view. As shown in figure 1, the microwave oven includes a resonator (microwave) 2, a chamber 10, a casing 4, a door 3, a magnetron 11, a transformer 12 and a fan 13.

The resonator 2 is a space in which food products are placed and which has an open front in order to place or remove food products. The chamber 10 is located next to the resonator 2 and there are many elements, including a magnetron 11, a transformer 12 and a fan 13. A high voltage is applied to the magnetron 11 to generate microwave radiation. The transformer 12 is used to convert electricity that is supplied from the network to high voltage electricity and to supply the converted high voltage electricity of the magnetron 11. The fan 13 cools many elements installed inside the chamber 10 and generates an air stream passing through the inside of the resonator 2. The casing 4 closes the resonator 2 and the outer part of the chamber 10, and the door 3 is connected on the front side of the chamber 10 with the resonator 2 for opening and closing the open front part of the resonator 2. Door 2 also has clear glass so that the inside of the resonator 2 can be seen through the open front.

In addition, recently on the lower surface of the resonator 2 establish a rotating pan. To this end, a plurality of elements including an electric motor for rotating the pallet are placed together. Thus, in addition to the mentioned elements in the microwave oven, there are many other elements, a detailed description of which will be omitted.

A microwave oven with the above construction works as follows.

To begin with, open door 3, then food products are placed in resonator 2, after which door 3 is closed. Microwave operation is controlled from a control panel (not shown). During operation of the microwave oven, the transformer 12 provides the conversion of electricity to high voltage and supplies the high voltage magnetron 11. A high voltage is applied to the magnetron 11 to generate microwave radiation, and the resulting microwave radiation is supplied to the resonator 2. The microwave radiation in the resonator 2 causes the water molecules of the food products to vibrate, while heating them. When exposed to microwave food for a certain period of time, they begin to heat up, so food can be thawed or cooked.

Since the aforementioned known microwave oven allows thawing or heating food products using the principle of vibration of water molecules of food products, it cannot be used to make many preparations. For example, a well-known microwave oven does not allow you to make coffee that a modern person likes to drink. In other words, in order to be able to drink coffee, you must use a coffee maker.

Meanwhile, in recent years, with the growth of urbanization of the population, there is a tendency to reduce living space and the aim is to increase practical expediency. As a result, it is necessary that many essentials, including household appliances, have a compact design. In addition, electrical household appliances are required to perform various additional functions, as well as traditional initial functions. However, the known microwave oven does not satisfy the needs of such consumers.

DETAILED DESCRIPTION OF THE INVENTION

The following is a more detailed description with reference to preferred embodiments of the present invention, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or similar parts.

First Embodiment

A first embodiment of the present invention provides a microwave oven having a coffee maker installed in the chamber of this electronic device. Since the structural features of the first embodiment of the invention are illustrated in FIGS. 2-4, the structure of the first embodiment will be described with reference to these drawings.

As shown in FIGS. 2-4, the microwave oven according to the first embodiment of the present invention includes a resonator (not shown), a resonator door 40, a chamber 50, a housing 100, a water tank 200, a funnel 300, a heater 600, a pipe 500 for water supply and jug 400.

The resonator is formed so as to have a predetermined space inside the frame 30. The front part of the resonator is open. The resonator door 40 is hinged to one edge of the front of the resonator to open / close the open front of the resonator. A tray (not shown) is rotatable on the bottom surface of the resonator. The tray, as provided, rotates the food so that the microwave irradiates the food more uniformly to achieve high heating characteristics.

The camera 50 is made near the resonator, for example, on the side of the resonator. Inside the chamber 50 of the electronic device, a plurality of electrical elements are installed to output microwave radiation into the resonator and thereby prepare food placed in the resonator. For example, a plurality of elements are installed inside the chamber 50, including, in particular, a magnetron 51, a transformer 52, a fan 53, and an electric motor (not shown).

In this case, external electric power is supplied to transformer 52 to convert external electric power into high voltage electric power, and high voltage electric power is supplied to magnetron 51 from transformer 52 to generate microwave radiation and output microwave radiation resulting from generation to the resonator through an antenna (not shown ) External electric power is supplied to the motor to rotate the tray. The fan 53 directs the external air towards the elements mounted inside the chamber 50, in particular the magnetron 51 and the transformer 52, which emit a large amount of heat to cool these elements. In addition, the fan 53 is designed to create a passage for the flow of air, which passes through the resonator and is brought out.

A housing 100 is provided for hosting a water tank 200, a funnel 300, a jug, and the like. The housing 100 has an open portion mounted, as shown in FIG. 2, on the front side of the interior of the chamber 50. In order to accommodate the housing 100 inside the chamber 50, electrical elements, a magnetron 51, a transformer 52, a fan 53, an electric motor, and the like are placed closer to the back of the chamber 50 compared to the known microwave. Since in the microwave oven according to the present invention, many elements are placed close to each other inside the chamber 50, it is preferable to improve the cooling conditions of the chamber 50 compared to the known microwave oven by improving the design of the cooling passage.

As shown in FIGS. 2 and 3, the water tank 200 is formed inside the body 100. The water tank 200 has a storage space for water and is located on the upper side of the interior of the body 100. The water tank 200 is so designed that when it is inserted into case 100, it has an entrance 210, not open towards the open front of the case 100, or has a hinge with one edge of the front of the case 100 so that it can be entered and removed from the inside of the case 100 by pushing and pulling with w pivotable about hinges (not shown).

As shown in FIGS. 2 and 3, if the water tank 200 has an inlet 210 that is open with respect to the outside, and water can be supplied in a position where the water tank 200 is not removed. Meanwhile, the inlet 210 can be designed so that it is opened directly to the outer part or opens whenever the case door 110 is opened, opening and closing the front part of the case 100. In the case where the inlet 210 is opened directly from the outside, preferably so that the water tank 200 is provided with a plug for opening / closing the inlet 210 (not shown). In addition, as shown in FIG. 2, in the event that the cabinet door 110 is formed on the front side of the cabinet 100, it is preferable that the inlet 210 is open to the outside when the cabinet door 110 is open and closed when the cabinet door 110 is closed. Of course, it is necessary that the inlet 210 and the door 110 of the housing are designed so that they do not interfere with each other when closing the door 110 of the housing.

Meanwhile, although this is not shown in the drawings, if the microwave oven is designed so that the water tank 200 has a loop connection to the housing 100, in case it is designed to supply water to the water tank 200, the water tank 200 is rotated around hinges for removing the water tank 200 and supplying water to the water tank 200 through an inlet (not shown) formed on one side of the water tank 200. If the water tank 200 is rotated around the loop after the water has been supplied to the water tank 200, then the water tank 200 will occupy a position within the housing 100, thereby providing a very convenient use.

In addition, although not shown in the drawings, the water tank 200 can be designed to supply water after it is completely removed. In this design, it is not necessary that the inlet of the water tank 200 is opened to the outside when the water tank 200 is placed inside the housing 100.

The water tank 200 can be configured so that part of it is attached to the body 100, but it is also possible to design when the water tank 200 is completely separated from the body 100. In the structure, when the water tank 200 is completely separated from the body 100, a support bracket is provided tank 200 for water. Although this bracket is not shown in the drawings illustrating the first embodiment, the bracket is clearly shown in FIG. 5 and FIG. 13, depicting the second and third embodiments. As shown in FIGS. 5 and 13, brackets that protrude and face each other on both sides of the inner wall of the housing 100 toward the interior space serve as a shelf for supporting and fixing the water tank 200 from the lower side of the water tank 200 . By mounting the bracket with the above construction, the invention allows a microwave oven having a simple and economical construction, since the user can remove the water tank 200 from the outside, supply water and re-position the water tank so that the water tank 200 supported by bracket.

The funnel 300 is configured to enter and exit from the interior of the housing 100 by pushing and pulling. In the first embodiment, as shown in FIGS. 2 and 3, the funnel is designed so that a body separated from the water tank 200 is made and placed below the water tank 200.

Although the internal structure of the pipe 300 is not shown in detail in FIGS. 2 and 3, the funnel 300 of the first embodiment is similar to the funnel of a known coffee maker. In other words, the funnel 300 has a conical shape in which the inner peripheral diameter of the upper part is larger than the inner peripheral diameter of the lower part. Inside a funnel 300 with the above construction, a filter (not shown) made of paper, non-woven material or the like is mounted, and coffee powder is collected on the filter. Since hot water is supplied to the funnel 300, the coffee powder dissolves and the coffee solution passes through the filter and flows downwards. For this purpose, a drip hole through which liquid coffee flows down in a dissolved state is provided below the funnel 300. If necessary, a coffee outlet valve can also be provided to open / close the drip hole under the action of an external force. The design for dripping coffee solution drops will be described in detail in the second and third embodiments below.

A first embodiment of the invention provides a jug 400 as a container for storing a solution of coffee that drips from the funnel 300. Underneath the funnel 300 is a jug 400 that is inserted and removed from the inside of the housing 100 by pushing and pulling. The jug 400 is made in the form of a vessel and there is a handle 410 on one side of it. Therefore, the user can easily insert or remove the jug 400 from the housing 100 by holding the handle 410. The jug 400 is preferably made of transparent glass or plastic so that it can be easily see the amount of coffee solution in it. The specific design of the jug 400 will be described in more detail in the second and third embodiments.

A heater 600, as shown in FIG. 4, is provided at the bottom of the housing 100 for heating a jug 400 mounted on the bottom surface of the housing 100. Consequently, the coffee in the jug 400 is always kept hot due to the heat transferred from the heater 600 .

In a first embodiment of the invention, a heating plate 160 is further provided. As shown in FIG. 4, the heating plate 160 forms the inner surface of the bottom of the housing 100 and is heated by contact with the heater 600 and transfers heat to the jug 400. For this purpose, the heating plate 160 is preferably made from a material having a high heat transfer coefficient. Part of the connection between the heating plate 160 and another part of the housing 100 is preferably made of heat-insulating material to prevent heat transfer from the heater 600 to a part other than the heating plate 160.

The water supply pipe 500 is configured so that one end 510 thereof is connected to the water tank 200, its other end 560 is located on the upper side of the funnel 300, and part of it is in contact with the heater 600. In more detail, one end of the water supply pipe 500 connected to the surface of the bottom or lower side of the housing 100. The body part of the water supply pipe 500 exits into the outer part of the housing 100, is in contact with a predetermined area with a heater 600 provided in the lower part of the housing 100, and again enters the interior of the housing 100 . D the other end 560 of the water supply pipe 500 is located above the funnel 300. Meanwhile, the other end 560 through which the water flows out is mounted above one end through which the water is introduced. This is necessary in order to prevent the leakage of water in the water tank 200 through the other end 560 in an unheated state due to a simple pressure difference. If the water supply pipe 500 is installed as described above, then the water located in the water tank 200 is introduced through one end 510 of the water supply pipe 500, is heated when passing through the part in contact with the heater 600, it rises due to steam pressure and is lowered into the pipe 300 through the other end 560. The portion of the water supply pipe 500 in contact with the heater 600 is preferably made of a material that has a good heat transfer rate for transferring heat from the heater 600 to the water flowing therein .

A check valve 550 is provided in the middle of the water supply pipe 500 to prevent water from flowing back into the water tank 200. Check valve 550 may have various designs. One example of a check valve having a simple design is described below.

One end portion 510 of the water supply pipe 500, i.e., a portion located closer to the water tank 200, has a relatively small inner diameter. The part adjacent to the heater 600 has an inner diameter slightly larger than the inner diameter of the part closer to the water tank 200. Among parts having different inner diameters, a ball (not shown) is provided in the inner part of the water supply pipe 500 having a slightly larger inner diameter. In this case, the ball cannot move freely inside the part of the water supply pipe 500 having a slightly larger inner diameter, and cannot move inside the part of the water supply pipe 500 having a slightly smaller inner diameter, having a size that allows it to block the water passage.

When the check valve 550 has the aforementioned structure, it prevents water from flowing back into the water tank 200 as follows.

Water entering the water supply pipe 500 from the water tank 200 passes through a non-return valve 550 and enters the part in contact with the heater 600. At the same time, since the ball is located in the lower part under the influence of gravity and water pressure , it does not block the passage for water having a small diameter. Since the heater 600 is heated, the water supply pipe 500 in contact with the heater 600 also heats with the water entering the water supply pipe 500. As the water in the water supply pipe 500 is heated, the internal pressure in the water supply pipe 500 rises, so the ball rises, blocking the water passage in the water supply pipe having a small inner diameter. Thus, if the inlet of the part having a small inner diameter is blocked, the water heated by the heater 600 does not rise towards the water tank 200, therefore, the reverse flow stops. If the water is additionally heated in a state where the reverse flow is stopped, the water rises towards the other end 560 of the water supply pipe 500, which is fully open, and then flows into the funnel 300. Since a certain amount of water rises due to the pressure of the water and flows through the other end 560, the internal pressure in the water supply pipe 500 is reduced and the ball is lowered, therefore, the water in the water tank 200 is lowered. When repeating the previous steps and heating the water, the heated water is supplied to the funnel 300 in a state where the reverse flow stops.

As described above, the present invention provides a check valve 550 having a simple structure and operating under the influence of water pressure, attractive force and vapor pressure. However, it is obvious that the present invention is limited only by check valve 550, which has the above construction. In other words, a separate valve can be installed to temporarily block the passage of water in the water supply pipe 500 when the water heats up and boils.

The microwave oven according to the first embodiment of the invention may further have a cabinet door 110 for opening / closing the open front of the cabinet 100. The cabinet door 110 is attached to one edge of the front of the cabinet 100 via a hinge 111. Preferably, the front of the cabinet door 110 has a surface, which is continuous with the resonator door 40 mounted next to it.

The cabinet door 110 is provided for opening / closing the entire portion of the open front of the cabinet door 110 so that the water tank 200, the funnel 300, and the jug 400 fit completely into the cabinet 100 when the cabinet door 110 is closed. However, since users often insert or remove the jug 400 from the microwave oven, it is preferable that the housing door 110 be designed to open / close parts where the water tank 200 and funnel 300 are placed other than the part where the jug 400 is located, as shown in FIG. .2. Accordingly, users take the jug 400 out of the housing 100 in order to drink coffee in a state where the housing door 110 is closed.

In a first embodiment, a front cover may be attached in the open front of the housing 100. The front cover has an opening connecting the inside of the housing 100 to the outside, and if necessary, a controller can further be provided to control the operation of the microwave and coffee maker. In addition, if necessary, it is possible to further provide a cover door for opening / closing the hole. A front cover with the above construction will be described in detail in the second and third embodiments with reference to the accompanying drawings.

The frame 30 and the chamber 50 are placed in a casing (not shown), which serves to protect the internal elements of the microwave oven.

The operation of the first embodiment with the above construction will be described below. Since a detailed description of the basic functions of heating food using microwave radiation and the corresponding contents of the microwave oven is already known in the prior art, a description thereof will be omitted. Hereinafter, a description will be given of work with emphasis on the functions of the coffee maker added to the microwave oven of the present invention.

First, a funnel 300 is removed from the housing 100 and a filter is installed in the inner region of the funnel 300. An appropriate amount of powder coffee is poured onto the filter and the funnel 300 is inserted into the housing 100. The jug 400 is washed cleanly and inserted into the housing 100 so that the bottom of the jug has contact with the heating plate 160. After the water has been supplied to the water tank 200, the user activates a coffee maker that is connected to the microwave.

Immediately after the coffee machine starts operation, the water supply pipe 500 and the heating plate 160 are heated by the heat generated by the heater 600. At the same time, water is supplied from the water tank 200 to the inside of the water supply pipe 500. The water that is supplied to the water supply pipe 500 is lowered and heated by the heater 600.

If the pressure in the water supply pipe 500 increases when water boils after a predetermined time, the ball closes the passage for water to flow in the water supply pipe 500. As a result, boiling water rises due to the high vapor pressure and enters the funnel 300 through the other end 560 of the water supply pipe 500. If hot water is supplied to the funnel 300, the powder coffee dissolves and the liquid coffee drips through the drip hole into the inside of the jug 400, thereby filling the jug 400. Meanwhile, since the jug 100 comes into direct contact with the heating plate 160 heated by the heater 600 , coffee can always be kept hot.

Meanwhile, the proper amount of hot water heated by the heater 600 is supplied to the funnel 300, and the pressure in the water supply pipe 500 decreases. Therefore, the ball begins to open a channel in the pipe 500 for supplying water. If the channel in the water supply pipe 500 is open, the water that is contained in the water tank 200 is again supplied to the portion adjacent to the heater 600. After that, the incoming water is heated by the heater 600 and fed to the funnel 300 through the other end 560 of the pipe 500 for water supply due to pressure. By repeating the above procedures, the entire amount of water that is contained in the water tank 200 is heated and fed to the funnel 300. Then, the coffee becomes liquid and accumulates in the jug 400.

Since the heating plate 160 keeps the coffee stored in the jug 400 hot, the user can always enjoy hot coffee by pulling out the jug 400.

The first embodiment of the present invention has the following advantages.

Firstly, in addition to the basic function of microwave radiation when heating food using microwave radiation, you can conveniently make coffee that modern people enjoy.

Secondly, since a coffee maker is provided in a chamber of a microwave oven having a relative free area of space, only if the electrical elements are tightly mounted in the chamber of the electronic device, it is not necessary to reduce the cavity space or increase the overall size of the microwave oven. As a result, you can save useful kitchen space.

Second Embodiment

The second embodiment of the present invention provides a microwave oven having a structure in which the water tank and funnel are made in the form of a single body in order to increase the practical use of the space, and the designs of various parts related to the water supply and making coffee in the coffee machine installed in the camera of an electronic device. In addition, the jug provides for various designs that allow you to boil eggs or make tea. Since the structural features of the second embodiment of the invention are clearly shown in FIGS. 5-12, the construction of the second embodiment will be described with reference to these drawings.

As shown in FIG. 5, a microwave oven according to a second embodiment of the present invention includes a resonator 20, a resonator door 40, a chamber 50, a housing 100, a water supply pipe 500, a water tank 200, and a funnel 300 made in a single body , jug 400, heater 600 and casing 60.

The resonator 20 is formed inside the frame 30 and has an open front. The resonator door 40 is configured to open / close the open front of the resonator 20. The chamber 50 is arranged on the side of the resonator 20 and has a plurality of electrical elements, including a magnetron 51, a transformer 52, a fan 53, and an electric motor (not shown).

A housing 100 is provided on the front side of the interior of the chamber 50. The water tank 200, the funnel 300, and the jug 400 are configured to enter and exit the interior of the housing by pushing and pulling. A heater 600 is provided at the bottom of the housing 100. The water supply pipe 500 is configured so that one end thereof is connected to the water tank 200, and the other end 560 is placed above the funnel 300, and part of it would be in contact with the heater 600 The casing 60 covers the frame 30 and the chamber 50 to protect the internal elements of the microwave oven.

In this case, the basic composition of the microwave oven, including the resonator 20 and the chamber 50, and the coffee maker elements, including the housing 100, the water supply pipe 500, the heater 600 and the heating plate, are described in detail in the first embodiment with reference to FIG. 2-4.

Therefore, their detailed description is omitted here. Only elements of the second embodiment that are different from elements of the first embodiment, or newly added elements will be described in more detail.

The front cover 130 is attached to the open front of the housing 100. As shown in FIG. 5, the front cover 130 has an opening in the interior of the housing 100 associated with the exterior. Therefore, users take out the jug 400 and the water tank 200 through the opening and place them in the interior of the housing 100. On the front cover 130, a controller button may be provided to control the operation of the microwave oven and coffee machine. The front portion of the front cover 130, made as described above, has a surface that is continuous with the front of the resonator door 40 in order to give a sense of beauty.

One of the technical features of the second embodiment is that the water tank 200 and the funnel 300 are made as a single body, as shown in FIGS. 5 and 6, and will be described in detail below.

The water tank 200 has a space for storing water and approximately in the upper part, for example in the part of the upper surface, has an inlet connecting the outer part with the inner part so that water can be supplied from the outer part. The lid 220 of the water tank is designed to open / close the inlet of the water tank 200. The funnel 300, as shown in FIGS. 5 and 6, has the shape of a concave cone, the outer diameter of which is larger than the lower diameter, since it

extends from the upper center of the water tank 200 to the bottom surface and forms the outer peripheral surface of the water tank 200. If the funnel 300 has the above-described structure, then it becomes possible to make a coffee maker with a more compact design than in the first embodiment, in which both the water tank 200 and the funnel 300 are located in the upper and lower parts. A filter is installed in the inner peripheral surface of the funnel 300, corresponding to the outer peripheral surface of the water tank and having the shape of a concave cone, and coffee powder is fed into the filter. The front portion 230 of the water tank 200 has a continuous surface with a front cover 130.

As shown in FIG. 6, the other end 560 of the water supply pipe 500 supplying hot water heated by the heater 600 to the funnel 300 is positioned so that when the water tank 200 is completely placed in the housing 100, it is located above the funnel 300.

In a second embodiment, the container consists of a jug 400. As shown in FIGS. 6 and 7, the funnel 300 further includes a coffee outlet valve 340 that controls the drip hole channel 310 so that the liquid coffee contained in the funnel 300 drips down only when the jug 400 takes its position in the housing 100.

The coffee outlet valve 340, which closes the channel of the drip hole 310, formed below the funnel 300, opens the drip hole 310 when the jug 400 takes its place inside the housing 100 and moves with the top of the jug 400. The coffee outlet valve 340, as shown in FIG. 7 includes an opening / closing member for directly opening / closing the drip hole 310, and a spring 330 providing elastic force to the opening / closing member 320.

The opening / closing element 320 includes a rod 321, a second end portion 323 and a first end portion 322. In this case, the rod 321 is configured to pass through the drip hole 310 formed below the funnel 300 and move up and down. The second end portion 323 is made wide at one end, for example, at the lower end of the rod 321, and moves upward due to contact with the upper surface of the jug 400 when the jug 400 takes its place in the housing 100. The first end portion 322 is made wide at the other end of the rod 321 for example, on the upper side of the rod 321, and opens the drip hole 310 when the second end portion 323 is pushed up by the jug 400 from the state in which the first end portion 322 closes the drip hole 310.

The second end portion 323 of the opening / closing member 320, as shown in FIG. 6, rises in contact with the top surface of the jug 400. When the jug 400 is inserted into the housing 100, the second end portion 323 makes sliding contact with the upper surface of the jug 400. To reduce friction in the sliding contact, the second end portion 323 has the shape of a bowl, the lower surface of which is convex in the downward direction. In the case where the second end portion 323 is made in the shape of a cup, coffee that drips down through the drip hole 310 may remain on the upper surface of the second end portion 323. In order to prevent coffee from being trapped on the upper surface of the second end portion 323, a plurality of through-holes are formed. holes 32 behind them into the inner part of the coffee jug 400, remaining on the upper surface of the second end portion 323.

A spring 330 is provided between the opening / closing member 320 and the funnel 300. More specifically, the spring 330 consists of a known compression spring that accumulates elastic energy when it is subjected to a compressive force in a direction along its length and then returns to its previous state when the compressive force is removed. As shown in FIG. 7, the spring 330 is configured so that its other end is in contact with and attached to the bottom surface of the funnel 300. Spring 330 always provides a force pushing the second end portion 323 downward. Therefore, a portion of the opening / closing member 320, in more detail, the first end portion 322 closes the drip hole 310, although it always maintains a state of tight contact with the drip hole 310 due to the force of the spring 330.

Let us briefly consider the operation of the spring 330. When the jug 400 is placed in the housing 100, if the second end portion 323 is in contact with the upper surface of the jug 400 and pushed, the first end portion 322 rises with the second end portion 323 so as to open the drip hole 310. At the same time, the spring 330 is compressed to accumulate elastic energy. On the other hand, when the jug 400 is removed from the housing 100 in a state when it is housed in the housing 100, the force pushing the second end portion 323 ceases to act, so the spring 330 returns to its original state. As a result, the second end portion 323 is lowered together with the first end portion 322 in order to close the drip hole 310.

In the coffee outlet valve 340, which operates in the aforementioned manner, the spring 330 is not limited to a coil-type compression spring. In other words, the spring 330 will be sufficient if it is placed between the opening / closing element 320 and the funnel 300, while providing a force that compresses the spring 330 in the downward direction. As another embodiment of the spring 330, there is a leaf spring, in which both ends are attached respectively to the second end part 323 and to the lower surface of the funnel 300 and which accumulates elastic energy due to deformation when the second end part 323 rises and returns to its previous state, when the external force applied to the second end portion 323 is removed in order to lower the second end portion 323.

The coffee vent valve 340 of the second embodiment of the present invention further includes an O-ring 325 (FIG. 1). In this case, an O-ring 325 is provided between the first end portion 322 and the bottom surface of the funnel 300, in which the drip hole 310 is formed, and functions to prevent water leakage by increasing the tightness when the first end portion 322 is in close contact with and closes drip hole 310.

In a second embodiment, a valve 250 for supplying water is provided. One end 510 of the water supply pipe 500 presses on the water supply valve when the jug 400 is fully inserted into the body 100 and open to supply water to the water supply pipe, while when the jug 400 is removed from the body 100, it closes so that prevent the leakage of water in the water tank 200 to the outside. Hereinafter, the design of the water supply valve 250 will be described in detail with reference to FIGS. 7 and 8.

The water supply valve 250 includes a valve body 251, a channel control plate 252, and a valve spring.

The valve body 251 has a space and also has an inlet 251b through which water flows from the water tank 200, and an outlet 251a through which water flows. This valve body 251 is configured to penetrate through one side of the water tank 200, in more detail, the lower surface of the water tank 200 or the lower side of the water tank 200 so that the inlet 151b is located inside the water tank 200 and the outlet 251a is located outside the water tank 200. On Fig shows an example implementation of the body 251 of the valve in the construction of the pipe. In Fig. 8, an outlet 251a is formed at the open end of the valve body 251 and has a diameter smaller than the inner diameter of the valve body 251. An inlet 251b is formed to penetrate through a support plate 255 inserted at the other open end 560 of the valve body 251. However, the valve body 251 is not limited only to the design of the pipe, both ends of which are open (Fig. 8). For example, in the valve body 251 (FIG. 8), although one end located inside the water tank 200 is completely closed, an inlet may be formed on the peripheral surface of the valve body 251 in the diameter direction.

The channel control plate 252 is inserted into the interior of the valve body 251 so that it moves along the interior of the valve body 251. It is desirable that the channel control plate 252 has an external diameter equal to the internal diameter of the valve body 251. The channel control plate 252, which is in a state in which the flow control plate 252 is in contact with the outlet 251a to block the outlet 251a, is compressed by one end 510 of the water supply pipe 500 in order to open the outlet 251a. This channel control plate 252 has a plurality of through holes (not shown) through which water flows in the case where the inlet port 251b is formed for penetration through the support plate 255 (FIG. 8). In more detail, a plurality of through holes are formed along a portion of the edge of the channel control plate 252. Then, the through holes are closed when the channel control plate 252 is in direct contact with the outlet 251a, although they are open for passing water through it when the channel control plate 252 is located separately from the outlet 251a. This design is not shown in the drawings, because anyone who reads the above description can easily compare such a design with a similar one. Meanwhile, in the case where the inlet 251b is formed on the peripheral surface of the valve body 251 in the diameter direction, the channel control plate 252 may not have through holes. In other words, in the case where the channel control plate 252 is in direct contact with the outlet 251a, the outlet 251a is closed so that no water flows out. However, if the channel control plate 252 moves toward the inlet formed on the peripheral surface of the valve body 251 in the diameter direction, the inlet communicates with the outlet 251a, so that the water in the water tank 200 flows into the outer part. This design is also not shown in the drawings, because anyone who reads the above description can easily compare such a design with a similar one.

The valve spring 253 is inserted into the interior of the valve body 251 to provide an elastic force allowing the channel control plate 252 to be in direct contact from the outlet 251a. In more detail, one end of the valve spring 253 rests on a support plate 255 or is attached to one side of the valve body 251, while the other end of the valve spring 253 is attached to the channel 252. The valve spring 253 installed in the manner described above creates a force that always pushes the plate 252 to control the channel toward the side of the outlet 251a. Since the valve spring 253 is compressed from one end 510 of the water supply pipe 500 and moves backward under compressive force, it accumulates elastic energy and then returns the channel control plate 252 to its original position under the action of the accumulated elastic recovery force. The valve spring 253 may take various forms, including the coil-type compression spring shown in FIG.

The water supply valve 250 constructed in the manner described above further includes an O-ring 524 in order to prevent water leakage by increasing the tightness when the channel control plate 252 is in direct contact with the outlet 251a of the valve body 251. An O-ring 524 is provided on an inner peripheral surface located between the outlet 251a and the channel control plate 252.

Meanwhile, the second embodiment provides a push pin 511 formed at one end of the water supply pipe 500 to efficiently operate the water supply valve 250 of the water tank 200. The pressure pin 511 extends from one end 510 of the water supply pipe 500 (FIG. 8) and when the water tank 200 is installed in the housing 100, it performs the function of pressing the plate 252 to control the channel of the water supply valve 250 and open the outlet 251a body 251 valves. When the outlet 251a of the water supply valve 250 is opened, the body 251 of the water supply valve 250 is completely inserted into one end 510 of the water supply pipe 500 so that water flows between the body 251 of the water supply valve 250 and one end 510 of the water supply pipe 500 water supply. To this end, one end 510 of the water supply pipe 500 has an outer diameter equal to or slightly larger than the outer diameter of the valve body 251. In order to increase the tightness when the valve body 251 is inserted at one end 510 of the water supply pipe 500, an O-ring 512 is further provided on the inner peripheral surface of one end of the water supply valve 500. If the O-ring 512 is configured as described above, in the case where the valve body 251 is inserted at one end 510 of the water supply pipe 500, the outer peripheral surface of the valve body 251 is inserted into the inner peripheral surface so as to further increase the tightness for prevent water leakage.

In a second embodiment, a check valve 550 is further provided to prevent backflow of water inside the water supply valve 250 and a heating plate for efficiently heating the jug 400. Their detailed description is omitted since this was described in the first embodiment.

Meanwhile, a second embodiment of the invention provides a jug 400 having various functions for boiling an egg and brewing tea. Hereinafter, various embodiments of the jug 400 will be described with reference to FIGS. 9-12.

The jug 400 includes a jug body 410 and a handle 420. The jug body 410 has a coffee storage space and a structure with an open top side. The body 410 of the jug is preferably made of clear glass or plastic so that the amount of coffee contained therein can be easily recognized. Of course, it is assumed that the body 410 of the jug can be made of opaque material.

The handle 420 extends on one side of the body of the jug 410 so that it can be easily held by the hand from the outside.

In a second embodiment of the invention, the jug further includes an element 430 reinforcing the edge of the jug and a lid of the jug 440 (FIGS. 9-12). Element 430, reinforcing the edge of the jug, is made to protect the inner and outer peripheral surfaces of the open upper side of the body 410 of the jug. A jug lid 440 is provided for opening and closing the open upper side of the jug body 410. In this case, the lid 440 of the jug can be made in the form of a completely separate body, as shown in Fig.9-12. In addition, although not shown in the drawings, the jug cover 440 may have a structure in which one side thereof is connected to a jug reinforcing element 430, or to the body of the jug with the possibility of turning on a loop (not shown) or turning and disconnecting near the loop . The lid of the jug has an entry hole 441 formed so that coffee dripping from the drip hole 310 of the funnel 300 passes through it.

In a second embodiment of the invention, the jug 400 has the basic composition described above, and may have various designs in order to perform additional functions for boiling an egg or brewing tea. Various embodiments are described below regarding these additional functions for the jug 400.

In one example shown in FIG. 9, the jug 400 further includes a pendant 431 and an egg cooking frame 450.

Suspension 431 passes in the form of a hook from the element 430, reinforcing the edge of the jug, into the inner part of the body 410 of the jug for fixing and hanging the object.

The cooking frame 450 has a mesh-like weave for accommodating at least one egg and is installed inside the body of the jug 410 by mounting a portion of the egg cooking frame 450 on the hanger 431. The following is a detailed description of the design of the egg cooking frame 450.

The egg cooking frame 450 includes a first element 460 and a second element 470. The first element 460 includes vertical elements 453 and horizontal elements 454 having an interlacing similar to a network. The first element 460 and the second element 470 are rotatably connected using a loop 451. On the one edge of the first element 460 and on one edge of the second element 470, for example, from opposite sides of the loop 451, hook 461 and hook holder 471 are respectively formed. The hook 461 protrudes from the first element 460, and the hook holder 471 protrudes from the second element 470. When the first element 460 and the second element 470 are folded and connected to each other, the hook 461 is connected and attached to the hook holder 471 so that the first element 460 and the second element 470 are attached in a connected state to each other.

The first element 460 and the second element 470, as shown in FIGS. 10 and 11, have a concave curved surface to accommodate approximately half of the outer peripheral surface of the eggs. Therefore, as shown in Fig. 9, if the first element 460 and the second element 470 are connected to each other, then it is possible to place the eggs in the inner space formed by concave curved surfaces. The corresponding concave curved surfaces formed in the first element 460 and the second element 470 are arranged as a configuration of a long semicircular channel. These concave curved surfaces can be made with two columns, as shown in FIG. 10, or with a single column, as shown in FIG. 11.

In the first element 460 and the second element 470, which have the aforementioned structure, the horizontal element 453 protrudes inward from the concave curved surface to support on both sides of the eggs mounted in the egg cooking frame 450. If the horizontal element 453 protrudes inward from the concave curved surface to support both sides of the eggs, then the movement of the eggs, which are placed in the frame 450 for cooking eggs, is prevented. The horizontal elements 453 can be placed in a wide range, as shown in FIG. 10, in order to support both sides of the egg in the length direction, or can be placed in a narrow interval, as shown in FIG. 11, in order to support both sides of the egg in the direction width. The height of the protrusion of the horizontal elements 453 placed in the aforementioned manner becomes different depending on the position in which the eggs are supported. In addition, the direction of placement of the eggs must be determined taking into account the dimensions of the body 100 and the jug 400. After determining the direction of placement of the eggs, the curvature of the concave surface curve, the number of columns and the spacing of horizontal elements 453 are also determined.

As shown in FIGS. 9-11, at least one fastener portion 452 protrudes at the end portion of the first element 460 or the end portion of the second element 470. The protruding fastener portion 452 is inserted into the suspension 431 shown in FIG. 9 and is locked in a state in which the frame 450 for cooking eggs is placed inside the body 410 of the jug.

12, another embodiment of the jug 400 is shown. As shown in FIG. 12, the jug 400 further includes a shelf 480 and a tea strainer 490.

As shown in FIG. 12, the shelf 480 includes a plurality of shelves, preferably a pair of shelves. A pair of horizontally arranged shelves protrudes from the element 430, reinforcing the edge of the jug, into the inner part of the body 410 of the jug. In addition, a tea strainer 490 is provided for receiving tea leaves, tea powder or the like, one end being fixed in a state in which one end is suspended and supported, and part of it is lowered into the water that is contained in the body of the jug 410. Tea strainer 490 includes a sieve 491 and a flanged edge. In this case, the sieve 491, as shown in Fig. 12, is formed in the form of a container, the upper side of which is open in order to have a place for tea in it. The flanged edge 492 extends in width along the open upper periphery of the sieve 491.

In another example, the jug 400 has a structure in which tea is brewed using a disposable tea bag. To this end, as shown in FIG. 12, a slot (not shown) or a cutout 481 for securing is provided. A slot is formed by cutting the shelf 480 inward from the outer peripheral surface of the shelf 480, and the cutout 481 for fastening is cut in the form of a wedge inward from the outer peripheral surface of the shelf 480. Insert or attach a thread into the slot or cutout 481 for fixing formed by the above method. connected to a tea bag or tea brewing apparatus, whereby users can make tea conveniently.

In a second embodiment of the invention having the above construction, the coffee maker operates as follows.

First, a water tank 200, made in the form of a single body together with a funnel 300, is removed from the housing 100 in order to pour water into it. Then, the water tank 200 is inserted into the body 100. The lower surface of the water tank 200 inserted in the body 10 rests on the bracket 120. After the water tank containing water is finally placed in the body 100, the coffee maker is controlled by a controller.
