Description

Electric heating kettle combined with ultraviolet light emitting diode

Technical Field

The utility model relates to an electric kettle combined with an ultraviolet light emitting diode (UV LED). And more particularly, to an electric kettle combined with an ultraviolet light emitting diode (UV LED) capable of sterilizing substances contained therein by irradiating ultraviolet rays to the inside of the electric kettle.

Background

In the conventional electric kettle, in order to sterilize the beverage or liquid contained therein, the heating coil is heated to 100 degrees or more to heat the contents. However, in the case of the above-described conventional electric kettles, which can perform a sterilization function only by a heating function, have a problem that the beverage contained therein cannot be directly consumed because they need to be heated to a high temperature, and the beverage can be consumed only after the temperature is sufficiently lowered after a certain period of time.

In particular, beverages or weaning foods consumed by infants must be sterilized. Therefore, parents use a method of heating to 70 degrees and then cooling in order to sterilize while feeding beverages or weaning foods to infants. At this time, the temperature must be sufficiently lowered for the infant to be able to use, and it may be difficult to lower to an appropriate temperature and much time may be required when lowering to a lower temperature manually using means such as a refrigerator.

In addition, the user performs the sterilization function by heating to a higher temperature in the same manner in the case where there is insufficient time for working hours, handling emergency services, and the like, but it is inevitable to take a lot of time to lower the temperature in the above-described case. Therefore, there is a need for an electric kettle that can sufficiently exhibit a sterilization effect without being heated to a high temperature.

However, since convection does not occur smoothly in the substances contained therein when the temperature is not raised, it is necessary to maximize the sterilization effect by ensuring the convection of the substances. However, the conventional electric heating kettles simply use a method of heating to a high temperature to generate convection, thereby maximizing the sterilization effect, and there is no method of sufficiently generating convection of substances contained therein while reducing the temperature. Therefore, if the conventional problem in the art, that is, the problem that convection cannot be sufficiently formed, can be solved by using the original configuration, that is, without adding another independent configuration, by merely changing the form and structure thereof, the object of the electric kettle that sterilizes the substances contained therein can be effectively achieved.

On the other hand, many users consider that the sanitation of the electric heating kettle cannot be guaranteed and the electric heating kettle is rejected to be used, even people carry the electric heating kettle of an individual for use. Therefore, there is an urgent need to develop an electric kettle with a high-efficiency sterilization function.

Detailed Description

Next, preferred embodiments to which the present invention is applied will be described in detail with reference to the accompanying drawings. The advantages, features and methods of accomplishing the same of the present invention will become more apparent from the following detailed description of the preferred embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed in the following, but can be implemented in various forms, and the following embodiments are only for more completely disclosing the present invention and describing the scope of the present invention more completely to those having general knowledge in the technical field to which the present invention belongs, and the present invention should be defined only by the scope of the claims. Throughout the specification, the same reference numerals denote the same constituent elements.

Unless otherwise defined, all terms (including technical and scientific terms) used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Furthermore, the terms used in general and defined in dictionaries should not be interpreted as having an idealized or exaggerated meaning unless expressly so defined. The terminology used in the description presented herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In this specification, singular words also include plural meanings unless explicitly mentioned otherwise.

Next, several embodiments to which the present invention is applicable will be described with reference to the drawings.

Fig. 1 is an oblique view of an electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) to which an embodiment of the present invention is applied, and fig. 2 is an exploded oblique view of an inner projection of the electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) to which an embodiment of the present invention is applied.

Referring to fig. 1, an electric kettle 1000 incorporating an ultraviolet light emitting diode (UV LED) to which the present embodiment is applied is a device for heating and sterilizing a substance stored therein. The electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) can be used for heating water, beverages, soups, or foods, and particularly, can be used for heating, keeping warm, or cooking weaning foods for infants. An electric kettle 1000 incorporating an ultraviolet light emitting diode (UV LED) can include a container portion 100, a lid portion 200, and a support portion 300.

The container portion 100 can be used for storing a substance, and is illustrated in a cylindrical shape in fig. 1, but is not limited to the above-described shape. The cover portion 200 can be used for covering the upper side of the container portion 100. A handle may be coupled to the cover 200, and a separate uv sterilization device may be mounted inside the handle, which will be described later.

The support portion 300 supports the container portion 100 below the container portion 100, and can perform a function of supplying power to the container portion 100. The support part 300 can include buttons for selecting various modes of heating the substance stored in the container part 100 and a display screen for displaying control information of the electric kettle 1000.

Referring to fig. 2, the electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) may be combined in a state where the container part 100 is combined on the upper side of the supporting part 300 and the cover part 200 is covered on the upper side of the container part 100.

In some embodiments, the container portion 100 may be formed of double glass, but is not limited thereto, and may be formed of various materials such as stainless steel and plastic. The container portion 100 may include a 1 st sterilization portion 110, a reflection portion 120, and a heating portion 130.

The 1 st sterilizing part 110 can be located at a lower end side portion of the inside of the electric kettle 1000. In several embodiments, the 1 st sterilization part 110 can be located inside the double glass. The 1 st sterilization part 110 can irradiate ultraviolet rays having a wavelength of 250 to 260nm or 300 to 400nm having a high sterilization power, but is not limited to the above-mentioned wavelength.

In several embodiments, the 1 st sterilization part 110 can be operated all the time when the electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) heats the contents. In several embodiments, the 1 st sterilizing part 110 can be controlled to operate only for a portion of the time according to the mode setting. For example, the 1 st sterilizing part 110 can be operated only within the first 5 minutes of the start of heating, or only within the last 5 minutes before the end of heating, or within 30 seconds after the end of heating, according to the mode setting. The mode in which the 1 st sterilizing part 110 operates is not limited to the above-described mode.

Since the electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) to which the present embodiment is applied can sterilize the substances stored in the container part 100 by the 1 st sterilization part, it is possible to maximize the sterilization effect as compared to the conventional electric kettle 1000 that performs the sterilization function only by the heating function. In addition, since the electric kettle 1000 combined with the ultraviolet light emitting diode (UV LED) can sufficiently sterilize the substances stored therein by the 1 st sterilizing part 110 even when the substances are heated at a low temperature, it is possible to effectively shorten the time required to heat the substances stored therein to a high temperature and the time required to cool the substances stored therein to a low temperature.

In particular, since the electric kettle 1000 combined with an ultraviolet light emitting diode (UV LED) to which the present embodiment is applied sterilizes a substance by the 1 st sterilization part 110, it can exhibit a special effect when heating weaning food for infants. Since food is excessively heated when high-temperature heat sterilization is performed on the weaning period food of the infant, the temperature thereof must be lowered again for the infant to eat, and it may be difficult to lower to an appropriate temperature and much time may be required when the temperature is lowered to a lower temperature artificially using means such as a refrigerator. However, since the electric kettle 1000 combined with the ultraviolet light emitting diode (UV LED) according to the present embodiment can sterilize the substance by the 1 st sterilization part 110 even in a state where the substance is not heated to a high temperature, it is possible to prevent a problem that it takes time to adjust the temperature. In the case as described above, the electric hot water kettle 1000 combined with the ultraviolet light emitting diode (UV LED) has an advantage of being able to be directly consumed by the infant without a process of cooling the substance after heating the substance to a set temperature (e.g., 45 degrees).

The 1 st sterilizing part 110 can irradiate ultraviolet rays from the lower side of the electric kettle 1000 to the direction in which the reflecting part 120 is located. The 1 st sterilizing part 110 may be installed at the front, rear, left, and right sides of the lower end of the electric kettle 1000. In several embodiments, the 1 st sterilizing part 110 can further include: and an angle adjusting part for adjusting the height of the ultraviolet ray irradiated to the reflecting plate by adjusting the vertical angle. In this case, since the height of the 1 st sterilizing part 110 can be adjusted, the ultraviolet rays can be variably irradiated to a desired height, and the substances stored inside can be uniformly sterilized.

The reflection part 120 can be attached to the inner side surface of the electric kettle 1000 so as to surround the inside of the electric kettle 1000. In some embodiments, the reflector 120 is a high-brightness reflector, and may be made of a material that reflects ultraviolet light. The reflection unit 120 can reflect the ultraviolet rays emitted from the 1 st sterilization unit 110. For example, the reflection unit 120 can transmit the ultraviolet rays emitted from the lower end of the electric kettle 1000 by the 1 st sterilization unit 110 to the upper side of the electric kettle 1000 by reflecting the ultraviolet rays.

In this case, the reflection part 120 is not formed in the entire inner side surface region of the electric kettle 1000, but can be mounted at a height of only a part of the side surface portion of the electric kettle 1000 which is irradiated with the ultraviolet rays. By installing the reflection part 120 only at a part of the height, the ultraviolet rays can be uniformly dispersed into the electric kettle 1000 while using the minimum ultraviolet rays.

In one embodiment, the reflection part 120 can be installed at a height at which the 1 st sterilization part 110 irradiates the ultraviolet rays. Since the reflection part 120 needs to function to disperse the ultraviolet rays irradiated from the 1 st sterilization part 110 throughout the inside of the electric kettle 1000 by reflecting the ultraviolet rays, there is a problem that the ultraviolet rays cannot be dispersed throughout the inside of the electric kettle if the reflection part 120 is not located at a position where the ultraviolet rays are irradiated. Therefore, the reflecting part 120 can be adjusted by the user to the height installed in the electric kettle 1000, or the 1 st sterilizing part 110 can automatically recognize the height irradiated with the ultraviolet rays and automatically adjust the installed height.

For example, the height of the reflection unit 120 can be manually adjusted by providing a reflection unit height adjustment unit (not shown) that can adjust the height of the reflection unit 120 and fix the reflection unit to the inner side surface of the container unit.

Alternatively, an ultraviolet ray height detecting unit (not shown) may be installed, which may automatically detect the height of the ultraviolet ray irradiated from the 1 st sterilizing unit 110 and automatically change the height of the reflecting unit 120 according to the height of the ultraviolet ray.

The heating unit 130 may be a heating coil capable of raising the temperature, but is not limited to the above configuration. In several embodiments, the heating part 130 can be located at a lower end of the inside of the electric kettle 1000. The heating part 130 may be formed in a corrugated shape when viewed from a side surface of the electric kettle 1000. By forming the heating part 130 in a corrugated form, rather than a linear form, the area of the heating part 130 that can provide a heating effect can be increased, thereby promoting convection of the substance stored in the container part 100.

The container portion 100 can be wirelessly connected to a user terminal such as a smartphone, and various operations can be controlled by the user terminal. The container portion 100 can be connected to a user terminal by a near field communication method such as Bluetooth (Bluetooth) or Zigbee (Zigbee). For example, the container portion 100 can be operated by an application installed in a user terminal, and for example, the user terminal can control ultraviolet irradiation of the sterilization portion of the droplet 1, adjust the position of the reflection portion, or control the temperature of the heating portion.

Since the heating part 130 is formed in a corrugated form as described above, it is possible to uniformly mix the substances stored in the container by convecting the substances stored in the container. Since the heating unit 130 is formed in a corrugated form, it is possible to transmit a corrugated wavelength to the substance stored in the container. The heating part 130 can maximize the sterilization effect of the 1 st sterilization part 110, so that the substance stored in the container can be uniformly sterilized by the 1 st sterilization part 110.

Further, since the heating unit 130 can be formed of a material that can reflect ultraviolet rays, ultraviolet rays can also be reflected. The overall shape of the heating part 130 may be formed in a corrugated shape, and when a surface of the corrugated shape is viewed in the vicinity of the surface, the heating part may be formed of a fine polygonal surface having a non-curved surface. In this case, the heating unit 130 can reflect the ultraviolet rays at a plurality of angles.

In the above, the general structure and function of an electric kettle 1000 incorporating an ultraviolet light emitting diode (UV LED) to which an embodiment of the present invention is applied are described with reference to fig. 1 and 2. Next, a detailed description will be given of a specific structure of the electric kettle 1000 and a sterilization method thereof with reference to fig. 3 to 6.

Fig. 3 is a partially enlarged view for explaining the lower side of the electric kettle 1000 in detail, which incorporates an ultraviolet light emitting diode (UV LED).

In fig. 3, the 1 st sterilization part 110 may be installed so as to irradiate light from the front, rear, left, and right sides of the lower end of the interior of the electric kettle toward the direction in which the reflection part 120 is located. Here, a front direction among front, rear, left, and right sides can refer to a direction in which a display screen of the support part 300 is located, a rear direction can refer to a direction opposite to the front direction, and a left-right direction can refer to a direction perpendicular to the front-rear direction. The 1 st sterilization part 110 is installed at the front, rear, left, and right sides, so that the entire substance stored in the container part 100 can be uniformly sterilized.

In fig. 3, although the front, rear, left, and right directions are not exactly the direction in which the display of the support 300 is located, for convenience of description, the description will be made on the assumption that the front, rear, left, and right directions refer to the direction in which the display of the support 300 is located. In fig. 3, the case where the 1 st sterilizing part 110 is attached to four positions, i.e., the front, rear, left, and right sides, is illustrated, but the number and the position thereof are not limited thereto.

The 1 st sterilization part 110 may be installed inside the double glazing, and in this case, the 1 st sterilization part 110 may be formed integrally with the container part 100. Therefore, the 1 st sterilizing part 110 can be installed inside the electric kettle in a configuration that does not occupy a separate space in the container part 100.

The heating part 130 can be installed at a lower end of the inside of the electric kettle, and a detailed structure and function of the heating part 130 will be described later.

Referring to fig. 4, the 1 st sterilizing part 110 can irradiate ultraviolet rays from the lower end of the electric kettle toward the direction in which the reflection plate is located, thereby irradiating ultraviolet rays to the entire inside of the electric kettle. The left and right 1 st sterilizing parts 110 can irradiate ultraviolet rays to the reflecting plates located at opposite positions on both sides, and the reflecting plates can reflect the ultraviolet rays irradiated from the left and right 1 st sterilizing parts 110 to reach the uppermost ends of the side portions of the electric kettle.

In fig. 4, the front-side 1 st sterilizing part 110 of the front-side and rear-side 1 st sterilizing parts 110 is omitted, but the front-side and rear-side 1 st sterilizing parts 110 can irradiate the reflecting part 120 with ultraviolet rays similarly, and the reflecting part 120 can reflect the ultraviolet rays irradiated from the front-side and rear-side 1 st sterilizing parts 110 to reach the uppermost end of the side surface part of the electric kettle.

Accordingly, the electric kettle combined with the ultraviolet light emitting diode (UV LED) to which the present embodiment is applied can radiate ultraviolet rays from a plurality of directions and reflect the ultraviolet rays by the reflection part 120, thereby achieving an effect of sterilizing the whole of the substances stored in the electric kettle.

Fig. 5a and 5b are schematic views illustrating a path through which convection of internal substances occurs by the heating part 130 located at the lower end of the electric kettle, and fig. 6 is an exemplary view illustrating temperature setting of heating wires marked on the supporting part 300.

Referring to fig. 5a, in several embodiments, the lower portion of the substance stored in the interior of the electric kettle by the heating part 130 is heated and ascends to the upper portion and the upper portion descends to the lower portion, so that the up-and-down convection occurs. In this case, the heating portion 130 may be formed in a corrugated form as described above. By forming the heating part 130 in a corrugated form, a heating device having a larger area than that formed in a straight line can be formed, and thus convection of substances stored in the electric kettle can be more effectively generated.

In one embodiment, the heating part 130 can be distributed over the entire area of the inner lower end surface of the electric kettle from one end portion to the other end portion. In this case, a partial region of the heating unit 130 may be heated at a temperature different from that of other regions. For example, the heating part 130 can heat at a relatively high temperature in a central region of the electric kettle and heat at a lower temperature in a peripheral region of the electric kettle. The heating part 130 enables stronger convection of the substances stored in the central region by heating at a higher temperature in the central region of the electric kettle and relatively weaker convection of the substances stored in the rim by heating at a lower temperature in the rim region of the electric kettle. In the case as described above, there is an advantage in that the substances stored in the electric kettle are better mixed than in the case where the heating part 130 is heated at the same temperature, so that all parts of the substances are uniformly sterilized and thereby the sterilization effect is maximized. On the contrary, the heating part 130 can heat the electric kettle at a higher temperature in the peripheral area and at a lower temperature in the central area.

In one embodiment, the heating unit 130 can select a heating priority mode for heating the entire area and a sterilization priority mode for heating only a part of the area, and change the heated area according to the selected modes. Accordingly, the heating unit 130 can rapidly heat the substance in the heating priority mode when rapid heating of the substance is required, and rapidly sterilize the substance in the sterilization priority mode when rapid sterilization of the substance is required.

In another embodiment, the heating part 130 can be located in the central area of the inner lower end surface of the electric kettle, as shown in fig. 5 b. In this case, the heating part 130 can sufficiently generate convection of the stored substances by performing concentrated heating in the central area of the electric kettle.

In still another embodiment, the heating part 130 can be located at a peripheral area of the inner lower end surface of the electric kettle. In the case as described above, the heating part 130 can sufficiently generate convection of the stored substances by performing concentrated heating at the edge area of the electric kettle.

Referring to fig. 6, the temperature of the heating part 130 can be set through the interface 310 marked in the supporting part 300. The temperature of the heating part 130 may be set in units of 5 degrees in a low temperature region, for example, 35 degrees, 40 degrees, 45 degrees, and 50 degrees, and may be set in units of 10 degrees at 50 degrees or more and 100 degrees. The heating unit 130 may be set to 5 degrees or more at 50 degrees or more and 100 degrees or less. The temperature unit for setting the heating unit 130 is not limited to this. Since the electric kettle combined with the ultraviolet light emitting diode (UV LED) of the present invention can be sterilized by the sterilizing part, the substance can be sufficiently sterilized even if the substance is heated at a low temperature of 40 to 50 degrees.

In the above, the detailed structure of the electric kettle and the sterilization method thereof are explained in detail with reference to fig. 3 to 6. Next, the structure and function of the 2 nd sterilizing part 220 coupled to the cover 210 will be described in detail with reference to fig. 7 to 12.

Fig. 7 is a schematic view for explaining the 2 nd sterilizing part 220 inserted into the lid 210 of the electric kettle.

The cover part 200 may include a cover 210 and a 2 nd sterilization part 220. The cover 210 can be used to cover the upper side of the electric kettle. In the cover 210, an insertion hole 211 into which the 2 nd sterilizing part 220 can be coupled can be formed.

The 2 nd sterilization part 220 may be configured in a handle form, and may irradiate ultraviolet rays into the interior of the electric kettle by being inserted into the cover 210. The 2 nd sterilization part 220 can include a head part 221 functioning as a handle and an insertion part 222 inserted into the cover 210. The 2 nd sterilization part 220 can be coupled to the cover 210 by rotating after the insertion part 222 is inserted into the cover 210. The 2 nd sterilizing part 220 can be coupled to or separated from the cap 210 in a modular fashion that can be disassembled and assembled with respect to the cap 210. The 2 nd sterilization unit 220 can control power supply by the switch unit 223.

The electric kettle with the ultraviolet light emitting diode (UV LED) incorporated thereto to which the present embodiment is applied can greatly improve the sterilization effect on the substances stored in the electric kettle by further sterilizing the substances stored in the electric kettle by the 2 nd sterilization part 220.

Fig. 8 is a schematic diagram illustrating an example in which the 2 nd sterilization part 220 that is modularized is used compatibly in a container other than an electric hot water kettle.

The 2 nd sterilization part 220 can be inserted into the lid 210 of the electric hot water kettle as shown in the left side of fig. 8, and can be inserted into the lid of a storage container, a plastic bottle, a box, a food vessel, etc. in the form of a box as shown in the right side of fig. 8 in addition to the electric hot water kettle. As described above, the 2 nd sterilization part 220 has a modular structure capable of being combined with various structures, so that it is possible to easily install the 2 nd sterilization part on various objects and to easily sterilize the substances stored therein using ultraviolet rays.

Fig. 9 is a cross-sectional view illustrating an internal structure of the 2 nd sterilizing part 220.

Referring to fig. 9, the head part 221 of the 2 nd sterilizing part 220 may include a switching part 223, a power supply part 224, a stopper 225, a control Printed Circuit Board (PCB)226, an ultraviolet printed circuit board (UV PCB)227, an ultraviolet light emitting diode (UV LED)228, and a tilt sensor 229.

The switch section 223 can cause the power supply section 225 to supply power by controlling the operation of the control Printed Circuit Board (PCB) 226. The power supply unit 224 may be configured to be a charging type, and may be charged through a Universal Serial Bus (USB) connected thereto after the plug is opened. The power supply section 224 can supply power to an ultraviolet printed circuit board (UV PCB)227, and an ultraviolet light emitting diode (UV LED)228 can irradiate ultraviolet rays under the control of the ultraviolet printed circuit board (UV PCB) 227. At this time, an ultraviolet light emitting diode (UV LED)228 can irradiate ultraviolet rays toward the center of the lower end of the electric kettle.

The inclination sensor 229 can stop the irradiation of the ultraviolet rays when the inclination of the 2 nd sterilizing part 220 is detected during the irradiation of the ultraviolet rays. The inclination sensor 229 can prevent an accident from occurring due to ultraviolet rays exposed to the outside when the cap 210 is suddenly opened or the 2 nd sterilizing part 220 is detached from the cap 210.

A hole through which ultraviolet rays of an ultraviolet light emitting diode (UV LED) can pass is formed in a central region of the insertion portion 222. On the upper side of the insertion portion 222, a 1 st coupling portion 2221 that can be coupled with the head portion 221 can be formed. On the lower side of the head part 221, a 2 nd combining part 2211 rotatably combined to the 1 st combining part 2221 can be formed. The 2 nd bonding portion 2211 enables the 2 nd sterilization part 220 to be used for purposes other than the use of the cover 210, for example, as a fixing bracket. The 2 nd combining part 2211 can be combined with the cover 210 by a bracket rotating manner, and can prevent the release when the bracket is blocked by the container by rotating in a counterclockwise direction.

The insertion portion 222 is rotatably coupled to the head portion 221 by a screw rotation method. That is, the head 221 can be rotatably coupled to the insertion portion 222. In the insertion portion 222, a tea net projection 2223 capable of attaching and detaching a tea net for filtering impurities in tea water can be formed.

By attaching a silicone mount for sterilization such as a thermos cup to the 2 nd sterilization part 220, it is possible to incorporate the sterilization part into a container having any opening size. In this way, the 2 nd sterilization part 220 can perform a sterilization function on containers having an arbitrary opening size. At this time, the silicone holder can be formed in a convex shape so as to be able to be pressed when the protrusion is pressed and to bring the inside of the inserted container into a vacuum state.

Fig. 10 is an upper side view and a lower side view of the cap 210 when the 2 nd sterilization part 220 is not inserted into the cap 210, fig. 11 is a schematic view illustrating a state where the 2 nd sterilization part 220 is inserted into the cap 210, and fig. 12 is a schematic view illustrating a state where the 2 nd sterilization part 220 of fig. 11 is rotated and coupled to the cap 210 when inserted into the cap 210.

Referring to fig. 10, in an upper side view of the 2 nd sterilization part 220 viewed from above, a head part 221 and a switch part 223 can be seen. In a lower side view of the 2 nd sterilization part 220 viewed from the lower side, an ultraviolet light emitting diode (UV LED)228 and an insertion part 222 can be seen. In a state where the lower side view of the 2 nd sterilization part 220 is viewed as shown in fig. 10, the insertion part 222 of the 2 nd sterilization part 220 is inserted into the cover 210 to be brought into a state as shown in fig. 11.

An insertion hole 211 can be openly formed in the cover 210 as shown in fig. 11. The insertion hole 211 can be a space into which the insertion portion 222 can be inserted. The insertion hole 211 of the cover 210 can be in a similar form to the insertion portion 222. In another embodiment, the cover 210 can include terminals to supply power to the 2 nd sterilization part 220 by contacting the terminals of the insertion part 222.

The 2 nd sterilization part 220 of fig. 11 can be coupled with the cap 210 in a manner as shown in fig. 12 by means of the rotation of the insertion part 222. At this time, the 2 nd sterilization part 220 can receive power supply by means of contact of the terminals of the insertion part 222 with the terminals of the cover 210. In the case as described above, the 2 nd sterilizing part 220 can receive power supply through the terminals of the cover 210 even when the power of the rechargeable battery is exhausted.

As described above, the 2 nd sterilization part 220 can be combined not only with the electric kettle but also with any configuration provided with an insertion hole into which the insertion part can be inserted and irradiated with ultraviolet rays. Since the 2 nd sterilization part 220 is small in size and portable and has compatibility with various devices, it is possible to sterilize beverages at any place and without external power supply by carrying only the 2 nd sterilization part.

In particular, the 2 nd sterilization part 220 can be coupled to a cap insertable into the 2 nd sterilization part or to a container compatible with an electric hot water kettle, and in the case as described above, there is an advantage in that only the 2 nd sterilization part 200 is required to conveniently sterilize the weaning period food or beverage outdoors by irradiating ultraviolet rays to the weaning period food or beverage.

In the above, the structure and function of the 2 nd sterilizing part 220 coupled to the cover 210 will be described in detail with reference to fig. 7 to 12.

The electric kettle combined with the ultraviolet light emitting diode (UV LED) according to an embodiment of the present invention can sufficiently sterilize the substances stored in the interior by using the 1 st sterilization part 110 and the 2 nd sterilization part 220, and can maximize the sterilization effect by using the heating part 130 to convect the substances.

Next, the filter cartridge 230 mounted to the cover 200 will be described in detail with reference to fig. 13 to 15.

Fig. 13 is a perspective view for illustrating a state in which the filter cassette 230 mounted in the cover 210 is coupled with the cover 210. The filter cartridge 230 is a filter coupled to the inside of the cover 210. A coupling protrusion 231 can be formed at the inside of the filter cartridge 230 to be coupled with the cover 210 in a rotary screw coupling manner such as a screw.

A stopper ridge can be formed at the lower end portion of the filter cassette 230 so as to be fixed to the inner wall of the cover 210. The stopper ridge of the filter cassette 230 can have elasticity so as to be coupled to the cover 210 in a pressed state by the elasticity and maintain the coupled state to the cover 210 by elastically restoring. The filter cassette 230 can be contact-coupled from the cover 210 by pressing the stopper sill. As an example, the filter cartridge 230 can be coupled to the cover 210 in a state where the user pulls the blocking threshold using the thumb and the index finger.

The manner of coupling the filter cartridge 230 to the cover 210 is not limited to the manner described above.

A central hole can be formed in the center of the filter cassette 230. The filter cartridge 230 can form a middle hole in a region where the 2 nd sterilization part 220 irradiates ultraviolet rays into the electric kettle. Thereby, the filter cartridge 230 can be coupled to the cover 210 without interfering with the ultraviolet rays irradiated from the 2 nd sterilizing part 220.

Inside the filter cassette 230, a chlorine remover 233 for removing chlorine (cl) contained in tap water or the like can be included. The chlorine remover 233 may be formed of chlorine removing ceramic balls, but is not limited to the above-described structure.

Fig. 14 is a schematic diagram for explaining a structure in which water is poured into the filter cassette 230 and then discharged, and fig. 15 is a schematic diagram for explaining a pouring portion 235 and a discharge portion 237 formed in the filter cassette 230.

Referring to fig. 14, the filter cartridge 230 may include an input portion 235 and a discharge portion 237. The input portion 235 is a region where a through hole is formed at a position corresponding to an open region formed at the upper side of the cover 210 and can be coupled to the nozzle 240. The input portion 235 can input water, beverage, etc. through the nozzle 240. The discharging portion 237 may be a region where a through hole is formed at a position corresponding to an open region formed at the lower side of the cover 210. That is, the input portion 235 and the discharge portion 237 may be located at positions that are spaced the farthest distance from each other around the center hole, instead of being located at positions corresponding to each other. As an example, the input portion 235 and the discharge portion 237 can be located in opposite directions with respect to the central hole in the filter cassette 230. Accordingly, the water introduced through the introduction unit 235 can sufficiently flow inside the filter cartridge 230 and then be discharged through the discharge unit 237.

The filter cartridge 230 can reduce the pressure inside the electric kettle by the discharging unit 237 and the inputting unit 235 during the process of inputting water into the electric kettle, and can discharge steam.

As shown in fig. 15, the input portion 235 is open when viewed from the upper side of the filter cassette 230, and the discharge portion 237 is open when viewed from the lower side of the filter cassette 230.

Referring to fig. 16, the 2 nd sterilization part 220 may be formed with a ventilation part 250, so that steam inside the electric kettle is discharged through the ventilation part 250. The 2 nd sterilization unit 220 may include a ventilation unit 250 and a ventilation fan 260.

The ventilation part 250 may be a pipe connected to the outside of the 2 nd sterilization part 220 from a region coupled to the container part. The ventilation unit 250 can discharge the steam generated in the container unit to the outside of the 2 nd sterilization unit 220. The ventilation fan 260 may be installed at a position where the ventilation unit 250 is opened to the outside of the 2 nd sterilization unit 220. The ventilation fan 260 can discharge the steam to the outside by using air circulation. Accordingly, the 2 nd sterilization part 220 can smoothly discharge the steam generated in the process of the temperature increase inside the electric kettle to the outside.

Although the embodiments to which the present invention is applied have been described above with reference to the drawings, those having ordinary knowledge in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features thereof. The embodiments described in the foregoing are therefore to be considered in all respects only as illustrative and not restrictive.
