The present invention relates to a microwave oven, and more particularly, to a structure of a coffee maker combined use microwave oven having a function of a coffee maker.

In general, a microwave oven (MWO) is a device for cooking food by the heat of intermolecular friction generated by disturbing the molecular arrangement of food by using a high frequency (about 2,450 MHz per second) as a heating source.

The microwave oven is used only for cooking general foods because it is made to apply microwaves to cooking objects and heat them.

However, recently, in order to increase space utilization, home appliances have been studied for products having a complex function that can perform various functions together instead of a product having only one role of the home appliance.

For example, as disclosed in Korean Patent Application No. 10-2002-0011704, a form in which a coffee maker for extracting coffee is simultaneously provided in the microwave oven is also commercialized.

The structure of the microwave oven having the conventional coffee maker is briefly introduced with reference to FIGS. 1 and 2 as follows.

First, as shown in FIGS. 1 and 2, a microwave oven having a conventional coffee maker includes a coffee maker on a space in front of the electric compartment 20 equipped with the magnetron 21 and the high voltage transformer 22 in the main body 10. By providing the unit 30 to improve the space utilization of the electronic room and to provide a microwave oven of various functions.

At this time, the coffee maker unit, the case 31, the drinking water container 32, the filter basket 33, the coffee pot 34, the heating heater 35, the water supply hose 36, the heating tube 37 and the supply hose 38 are comprised.

Here, the case 31 is formed integrally with the door panel 31a forming an appearance together with the front frame 11 forming the front surface of the microwave oven body 10 and the rear surface of the door panel 31a. It is configured to include a case body 31b surrounding each component of the coffee maker.

In addition, the filter basket 33 is provided at the bottom of the drinking water container 32, and is formed to have coffee and paper filters embedded therein, thereby substantially extracting coffee.

In addition, the coffee pot 34 is provided at the bottom of the filter basket 33, and the coffee extracted through the filter basket 33 is stored.

In addition, the heat heater 35 is provided on the bottom surface of the case 31 which is the bottom of the coffee pot 34.

In addition, the heating tube 37 is formed along the heating heater 35, and is configured to heat the drinking water flowing therein by the heating of the heating heater 35.

In addition, one end of the water supply hose 36 is connected to the drinking water bottle 32, and the other end thereof is connected to the heating tube 37, and the drinking water stored in the drinking water bottle 32 is transferred to the heating tube 37. It serves to convey.

In addition, one end of the supply hose 38 is connected to the heating tube 37, and the other end thereof is positioned above the filter basket 33 to filter the drinking water heated while passing through the heating tube 37. It serves to guide the top of the basket 33.

Therefore, when a function of the coffee maker is made in a state in which a paper filter (not shown) in which coffee is put into the filter basket 33 is made, the heating tube 37 generates heat while the heating heater 35 is heated. Is heated and the drinking water present in the heating tube 37 is supplied to the filter basket 33 through the supply hose 38 while boiling by heating of the heating tube 37.

At this time, coffee is extracted by continuously supplying drinking water stored in the drinking water container 32 by the water supply hose 36 into the heating tube 37, and the extracted coffee passes through the filter basket 33. Stored in the coffee pot 37.

However, as described above, a hybrid product in which a coffee maker function is added to a microwave oven has a disadvantage in that control for each function must be made separately.

In other words, if the two functions are performed at the same time, excessive current consumption is generated, resulting in a risk of fire, etc., and a problem of deviating from the specification for current consumption.

For example, considering that the current limit value of the current microwave oven is 15 [A], when the magnetron is operated to cook the food and the heating heater for coffee extraction is generated, the current required for each operation is combined. The total current consumption is 21 [A], which greatly exceeds the limited 15 [A].

Therefore, in the case of a composite product, if the standard of the current consumption is to be met, when the two functions are operated simultaneously, the current consumed must be provided within the range of the standard current.

In particular, when the coffee maker includes a function for extracting the coffee and at the same time includes a function of insulating the extracted coffee, it is impossible to use the function in the microwave oven when a long time coffee is required. Have problems.

The present invention has been made to solve the conventional problems as described above, providing a microwave oven in which the coffee maker is integrally formed, it is possible to use the function in the microwave oven while the warming function of the extracted coffee is performed It is an object of the present invention to provide a coffee maker part of a microwave oven combined with a coffee maker.

According to an aspect of the present invention for achieving the above object, and provided in the inner space of the microwave oven, and forms a separate partitioned space; A drinking water passage provided in an upper space in the case to store drinking water; A filter basket is accommodated therein, and the filter basket in which coffee is extracted; A coffee pot provided on the bottom space of the case and storing the extracted coffee; A hot water supply unit configured to supply drinking water in the drinking water tank to the filter basket; A heating heater part provided at an outer bottom of the case to heat drinking water flowing through the hot water supply part; And, the present invention is provided on the outer bottom surface of the case to provide a coffee maker part of the microwave oven for coffee maker, characterized in that it comprises a: a heating heater for heating the coffee pot to a warming temperature.

Hereinafter, an embodiment of a coffee maker case of a coffee maker and microwave oven according to the present invention will be described in detail with reference to FIGS. 3 to 6.

At this time, the same reference numerals are given to the parts not shown in Figs.

First, the coffee maker part of the microwave oven according to the present invention is largely a case 110, a drinking water container 120, a filter basket 130, a coffee pot 140, a hot water supply unit, a heating heater And a heat insulating part.

Here, the case 110 is provided on the front side space of the electric compartment, which is the internal space of the microwave oven, and forms a separate partitioned space.

At this time, the outer bottom surface of the case 110 is further provided with a thermal conductive plate 111 formed of a thermally conductive material.

In addition, the front of the case 110 is provided with a door panel 112 to form an appearance with the main body of the microwave oven.

In addition, the drinking water container 120 is provided on the upper space in the case 110, the drinking water is stored therein.

In addition, the filter basket 130 has a sieve (not shown) is accommodated therein, and coffee is extracted.

At this time, the filter basket 130 may be provided at the bottom of the drinking water container 120, but more preferably configured to achieve a state accommodated in the drinking water container 120 as shown in the embodiment.

That is, the filter basket 130 is accommodated in the drinking water container so as to lower the overall height of the coffee maker.

The hot water supply unit is connected to supply the drinking water in the drinking water container 120 to the filter basket 130.

At this time, the hot water supply unit may be formed of a single pipe, but also includes a water supply hose 151, a heating tube 152, a plurality of pipes connected to each other, such as a supply hose 153, the supply It is more preferable to include a shower head 154 for supplying the hot water provided by the hose 153 into the filter basket 130, it is proposed in the embodiment of the present invention configured as described above.

This is to make the heating water more smoothly by forming the heating tube 152 with a metallic material.

In addition, the heating heater is provided to the outer bottom of the case 110 is configured to heat the drinking water flowing through the heating tube 152 of the hot water supply, and is configured to have a power consumption of approximately 750W.

The heating heater is preferably formed to surround the outer circumference or the inner circumference of the heating tube 152 constituting the hot water supply, it is more preferably configured as a sheath heater (160).

At this time, the sheath heater (160) is a type of heater formed by filling and compressing the heating wire in a metal protective tube together with magnesium oxide (Mgo), which has thermal conductivity and insulation.

In addition, the sheath heater 160 has a first power supply terminal 161 to which a coil (not shown) for power supply is connected at both ends thereof, and a heat conducting plate 111 provided on an outer bottom surface of the case 110. It is configured to be fixedly mounted in the center of the approximately.

In addition, the warming heater unit is provided to be in close contact with the heat conduction plate 111 provided on the outer bottom of the case 110, and serves to heat the coffee pot 140 to maintain the warming temperature.

In this case, a pair of second power supply terminals 171 are integrally formed at one end of the bottom surface of the heater portion, and each of the second power supply terminals 171 is a pair of coils 182 for power supply. Connected with

The warming heater unit is configured to have a low power consumption, for example, a power consumption of approximately 90 W, compared to the heating heater unit.

This is to enable the function of the microwave oven in the process of continuously operating the warming heater.

That is, when the insulation heater is configured to have a power consumption of approximately 90W, even when the insulation heater and the microwave are driven simultaneously, only 14.5 [A] of current is consumed, thereby satisfying the current limit specification value.

In particular, the insulation heater portion is formed of a plate heater (plate heater) 170 formed in a flat shape is formed with a relatively low power consumption, but is configured to have a maximum contact area.

In addition, except that the second power supply terminal 171 of the plate heater 170 is formed so as to surround the metal plate 172 of the heat conductive material as a whole to further improve the heat transfer effect More preferred.

However, in the above-described configuration, each second power supply terminal 171 of the plate heater 170 has a problem that contact with the metal plate 172 may occur.

Therefore, in the embodiment of the present invention, it is proposed to further include an insulating portion 173 surrounding the circumference of each of the second power supply terminals 171.

Here, the insulating portion 173 is preferably formed of a non-conductive material such as a ceramic material.                     

In addition, the insulation portion 173 is more preferably formed so that the exposed portion of each of the second power supply terminal 171 has a height sufficient to ensure the most stable insulation distance.

That is, even if the second power supply terminal 171 is bent or tilted to one side, the exposed portion is formed at a height such that the metal plate 172 does not come into contact with the exposed portion.

In particular, in the above-described series of configurations, it is more preferable that at least two conductive wires 174 are wound around the second power supply terminal 171.

This is because when the second power supply terminal 171 is made of a single core wire, the skin effect, that is, when a current flows through the core wire, induced electromotive force is generated inside the core wire, thereby causing a problem of interrupting the flow of current. Because.

Of course, there is also a problem that the connection portion between the second power supply terminal 171 and the power supply coil 182 can be easily disconnected.

Accordingly, by winding a plurality of conductive wires 174 around the second power supply terminal 171, the surface area formed by the core wire of the second power supply terminal 171 is increased to reduce the resistance, and thus, the flow of current is reduced. In addition to being made smoothly it is possible to lower the heat.

In addition, it is more preferable that the plurality of conductive wires 174 wound on the second power supply terminal 171 can be prevented from being disconnected from each other by connecting to the power supply coil 182.

At this time, it is preferable to improve the insulation effect by surrounding the connection portion between the conductive wire 174 and the coil 182 to be wrapped with an insulating tube 175.

In the embodiment, the insulating tube 175 is formed of an insulating material such as silicon rubber.

On the other hand, in the above-described series of configuration according to the embodiment of the present invention, the front side of the heat insulation heater is located on the bottom surface of the door panel 112, the front side of the door panel 112 to form the appearance of the microwave oven in general Therefore, in consideration of being formed of an ABS material, there is a problem that the bottom surface of the front side of the case 110, that is, the bottom surface of the door panel 112, may be damaged by the heat of the insulation heater.

Accordingly, in the embodiment of the present invention, it is proposed that the heat shield plate 176 is further provided on the bottom front side of the plate heater constituting the heater unit for blocking heat transfer.

That is, even if the plate heater 170 generates heat, the high temperature heat is prevented from being transferred to the bottom surface of the door panel 112, which is the bottom surface of the front side of the case 110, by the heat shield plate 176. It is.

Hereinafter, a process of operating the coffee maker unit of the microwave oven according to the embodiment of the present invention configured as described above is as follows.

First, if the user wants to extract the coffee while receiving the filtering net in the filter basket 130 with the drinking water supplied to the drinking water tank 120 equipped with the filter basket 130 and then put the coffee beans in the filtering net The drinking water container 120 is stored on the upper space of the case 110.

In this state, if power is supplied to the coffee maker unit, the sheath heater 160 of the heating heater unit generates heat and heats the drinking water in the heating tube 152.

At this time, the drinking water stored in the drinking water tank 120 is continuously supplied to the heating tube 152 through the water supply hose 151, the heat generated by the sheath heater 160 in the process of passing through the heating tube 152. The drinking water heated by the (hot water) is supplied to the shower head 154 while rising in the supply hose 153 by the vapor pressure is sprayed into the sieve of the filter basket 130.

Then, the extraction of coffee is made by hot water sprayed into the sieve, and the extracted coffee is stored in the coffee pot 140.

When the extraction of the coffee is completed by the above process, the power supplied to the sheath heater 160 of the heating heater unit is cut off and at the same time, the power supply to the plate heater 170 of the heater unit for keeping the extracted coffee is maintained. Is done.

Accordingly, the plate heater 170 generates heat, and the heat generated from the plate heater 170 is transferred to the coffee pot 140 accommodated in the lower space of the case 110 through the heat conduction plate 111. The coffee pot 140 may be maintained to maintain a proper warming temperature.

At this time, since most of the heat generating portion is in close contact with the heat conductive plate 111, the heat generated from the plate heater 170 is mostly transmitted to the heat conductive plate 111. Due to the low heat consumption due to the heat is made it is possible to keep the coffee pot 140 smoothly.                     

In particular, since the plate heater 170 has a power consumption of approximately 90W, the function of the microwave oven can be used even during the operation of the plate heater 170.

Of course, the bottom surface of the door panel 112 may be damaged by the heat generation of the warming heater unit, that is, the plate heater 170 while the aforementioned warming function is performed.

However, since the heat shield plate 176 is provided between the plate heater 170 and the bottom of the door panel 112, the heat generated by the plate heater 170 is transferred to the bottom of the door panel 112. It is possible to prevent the provided to prevent damage to the bottom of the door panel 112.

As described above, the coffee maker combined microwave oven according to the present invention has a heating heater part used to extract coffee and a warming heater part used to keep the extracted coffee, respectively, thereby keeping the extracted coffee warmed. It has the effect of enabling the use of the function in the microwave oven while the function is being performed.

In particular, the insulation heater is formed of a plate-shaped heater, and the bottom surface of the case portion forming the coffee maker portion is provided with a heat conduction plate so that the plate heater is in close contact, so that even if the plate heater is heated at a relatively low power consumption, the extracted coffee is smooth. It has the effect of keeping warm.

In addition, according to the configuration of the coffee maker according to the present invention, a problem that may occur when the warming heater part is configured as a plate heater, that is, a problem that each second power supply terminal of the plate heater may contact the metal plate is By providing an insulating part made of a ceramic material in the second power supply terminal, there is an effect that a problem with a short circuit can be prevented in advance.
