Description

Electric kettle {Electric kettle}

The present invention relates to an electric kettle, and more particularly, to an electric kettle provided with a water outlet.

In general, an electric kettle refers to a device that heats water or the like accommodated in a main body by a heating means such as a heater by supplying electricity.

And, most of these electric kettles are configured so that the main body is detachable from the base to which power is supplied, heated while seated on the base, and can be used by holding the handle and lifting the main body from the base. Electric kettles of this type are commonly called various names such as cordless electric kettles, cordless electric pots, and coffee pots.

Such an electric kettle may have a complex body shape and may be formed of a plastic material to facilitate the arrangement of internal components.

However, when used for a long period of time, there is a problem that not only harmful components of plastic or micro plastic components can be dissolved in high temperature water, but also vulnerable to scratches, and thus internal contamination problems may occur.

In addition, when the main body is formed of a glass material, it is hygienic and has excellent appearance, but there is a risk of damage due to impact, etc., heavy weight makes it difficult to use, and molding is not easy.

Therefore, as in Korean Patent No. 10-1631556, a technique in which a container is made of a ceramic material is disclosed.

However, in this prior art, since the spout through which the water inside the container is discharged is integrally formed with the container (body), manufacturing is difficult. In addition, when the spout does not have a structure for filtering out foreign substances, and there are ingredients inside the container, there is a problem in that these ingredients are discharged together with water (liquid) through the spout.

In addition, Korean Patent Registration No. 10-1794021 ('Blender and Steamer Combination Electric Pot') discloses a technology in which a filter is provided inside the spout.

However, even in this prior art, since the filter is detachably installed inside the spout, manufacturing efficiency is reduced, and since the spout is integrally formed on the top of the container, there is still a problem in that manufacturing is difficult.

On the other hand, in US Patent No. US 9,226,610 B2, a screen insert is further provided on the spout to filter out foreign substances, but since the screen insert is formed in a separate structure provided on the top of the body, the structure is complicated and the manufacturing cost is excessive. Of course, since the spout is integrally formed on the top of the body and protrudes, molding is difficult.

In addition, Korean Patent Publication No. 10-2021-0117548, filed to solve the above problems, has solved the problems of the prior patents, but the water outlet hole (water outlet hole) is narrow, so when the water inside the body boils It is difficult to discharge the steam, and when the steam is discharged through the outlet (outlet), there is a problem in that the water is spit out to the outside due to being liquefied by the cold air from the outside and turned into water. In addition, since there is a ridge between the outlet and the body or the bottom of the outlet is flat, water remains in the outlet even after pouring the water inside the body to the outside, causing problems such as contamination.

Korean Patent Registration No. 10-1631556 Korean Patent Registration No. 10-1794021 US Patent No. US 9,226,610 B2 Korean Patent Publication No. 10-2021-0117548

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and an object of the present invention is to provide an electric kettle in which a water outlet assembly is separately provided on one side of a body to be assembled.

An object of the present invention is to provide an electric kettle in which steam inside the body is smoothly discharged through an outlet.

An object of the present invention is to provide an electric kettle in which the area of the water outlet hole formed at the outlet is relatively larger on the upper side than on the lower side.

An object of the present invention is to provide an electric kettle having a structure in which water from an outlet is introduced into the body by a load.

According to a feature of the present invention for achieving the above object, in the electric kettle according to the present invention, the bottom surface of the water outlet is formed to have an inclination. Therefore, water from the outlet can easily flow into the body.

In the electric kettle according to the present invention, the height of the lower end of the water outlet hole is lower than that of the lower end of the water outlet hole. Therefore, water accumulation in the outlet is prevented.

In the present invention, the area of the upper water outlet hole among the plurality of water outlet holes is formed larger than the area of the lower water outlet hole. Therefore, the flow of water or fluid through the outlet hole becomes smooth.

An electric kettle according to the present invention includes a body accommodating water or food therein, a lid shielding an open upper side of the body, and a lid protruding from the side of the body so that the liquid inside the body is discharged to the outside. It has a configuration including a water outlet for guiding and a water outlet hole formed to penetrate the body and guiding water inside the body to be discharged to the outside through the outlet; The water outlet hole is characterized in that the area of the upper half is larger than the area of the lower half.

The water outlet hole is characterized in that it is formed vertically and long.

The water outlet hole is characterized in that a plurality is provided at the upper end of the body.

The plurality of water outlet holes are characterized in that the size of the water outlet hole located on the upper side is larger than the size of the water outlet hole located on the lower side.

The plurality of water outlet holes are characterized in that they are formed in a circular or slit shape.

The water outlet hole is made up of a plurality, characterized in that a slit-shaped water outlet hole is located on the upper side and a circular water outlet hole is located on the lower side.

The size of the slit-shaped water outlet hole is larger than that of the circular water outlet hole.

The lower end of the water outlet is characterized in that it is formed inclined.

The lower end of the water outlet hole is formed at a position lower than the lower end of the water outlet hole.

A lower end of at least one of the plurality of water exit holes is formed at a position lower than the lower end of the water exit hole.

The electric kettle according to the present invention has the following effects.

However, in the present invention, a water outlet assembly capable of pouring water inside the body is separately provided and assembled to the double body. Therefore, compared to the case where the water outlet is integrally molded with the body, there is an advantage in that the manufacturing efficiency is improved because the manufacturing of the body is easy.

Second, in the present invention, a filter function for filtering out foreign substances (dry matter) in the liquid discharged through the water outlet assembly is integrally formed in the body. That is, a plurality of outlet holes are formed in the inner body to serve as a filter to prevent foreign substances inside the body from being discharged to the outside. Therefore, since a separate filter is unnecessary, manufacturing efficiency is improved and management is convenient.

Third, in the present invention, a plurality of water outlet holes are perforated on the upper side of the body or inner body, and these water outlet holes are arranged so that the number of the upper water outlet holes is greater than the number of the lower outlet holes. That is, the number of water exit holes perforated at the same height increases from the lower part of the body or the inner body to the upper part, so that a plurality of water exit holes are arranged in an inverted triangle shape as a whole. Therefore, when pouring water from the electric kettle, convenience of use can be increased because the amount of discharged water increases in proportion to the angle of inclination. That is, the more the electric kettle is tilted, the more the amount of discharged tea water increases.

Fourth, in the electric kettle of the present invention, the lower end of the water outlet for guiding water inside the body to the outside is inclined inward (body side). Therefore, there is an advantage in that the steam or water that has moved from the inside of the body to the outlet can be easily returned to the inside of the body again.

Fifth, in the electric kettle of the present invention, the lower end of the outlet hole formed in the body is lower than the height of the bottom surface of the outlet port. Therefore, since the jaw does not exist between the outlet and the body, the water in the outlet automatically flows down to the body by gravity, thereby preventing water accumulation inside the outlet.

Sixth, in the electric kettle of the present invention, the water outlet holes are formed vertically and the area of the plurality of outlet holes is relatively larger on the upper side than on the lower side. Therefore, when the water inside the body boils, steam is discharged through the upper outlet hole, and the water inside the outlet is cooled by the external atmospheric pressure and returned to the inside of the body through the lower outlet hole, so it is easy to increase or discharge and return water. There are advantages to doing it.

After inserting into the packing fixing end 312a, inserting the packing part 322b of the packing body 32 into the packing seating groove 313 completes the assembly.

Also, the water extraction assembly 30 may be formed of a stainless steel material like the body 10 . Therefore, it is not easy to fix the water extraction assembly 30 to the body 10.

The water extraction assembly 30 is preferably coupled to the body 10 by welding. That is, in a state where the water extraction assembly 30 is in contact with the inner body 12, heat is applied to the welding protrusion 314 with an electrode to fix the water outlet 31 of the water extraction assembly 30 to the inner body 12 can do.

The welding method may be performed by direct welding or series welding.

That is, direct welding in which a (+) electrode is connected to the water outlet 31 of the water outlet assembly 30 and a (-) electrode is connected to the inner surface of the inner body 12 in contact with the welding protrusion 314. you can do it in a way

In addition, by series welding in which both the (+) electrode and the (-) electrode are connected and welded to the inner surface of the inner body 12 while the water outlet 31 is brought into contact with the inner body 12 It will also be possible to couple the water extraction assembly 30 to the body 10 .

For example, series spot welding is spot welding performed by passing current from two electrodes on the same side through a base plate electrode called a back bar (sometimes not used), and the shape and size of the object to be welded It is a welding method that has a great advantage in that it can weld from one side where the free space allows when it is difficult to carry an electrode on the back side like in normal direct spot welding.

Therefore, when the water outlet assembly 30 is coupled to the body 10 by series welding, no welding marks are left on the outer surface of the outer body 11.

In this way, coupling the water extraction assembly 30 to the body 10 by welding may also be used in other embodiments to be described below.

20 to 22 show another embodiment of the water outlet hole 125 and its applied state. That is, FIG. 20 shows a partially enlarged view showing another embodiment of the water outlet hole 125, and FIGS. 21 and 22 show a partial perspective view and a cutaway perspective view showing a state in which another embodiment of the water outlet hole 125 is applied. each is shown.

As shown in these drawings, the water outlet hole 125 may be vertically formed in the body 10 to be long. That is, it may have a slit shape in which the upper and lower lengths are greater than the left and right widths. A plurality of water outlet holes 125 are formed side by side in the inner body 12, and preferably have an inverted triangular shape to correspond to the inner end of the water outlet 31. Therefore, it is preferable that the vertical length of the water outlet hole 125 in the center is larger than the vertical length of the water outlet hole 125 on the left and right (in FIG. 20).

As such, a plurality of water outlet holes 125 are provided at the upper end of the body 10 to guide water or steam inside the body 10 to be discharged to the outside. In addition, when the water outlet hole 125 is formed vertically, the size of the water outlet hole 125 is increased as a whole, so that steam generated when the water inside the body 10 of the electric kettle boils is smoothly discharged. That is, since the water outlet hole 125 is vertically long, and the area of the upper half is larger than the area of the lower half, steam can be smoothly discharged through the water outlet hole 125 of the upper half having a relatively larger area. can

Meanwhile, the lower end 31a of the water outlet 31 may be inclined. That is, as shown, the bottom surface 31a of the water outlet 31 preferably has a slope gradually decreasing in height toward the inner end 31b (right end in FIG. 22). This is so that the water in the electric kettle according to the present invention or the steam coagulated at the outlet 31 does not accumulate on the bottom surface of the outlet 31 and flows into the body 10 by gravity by itself. is to do

The lower end 125a of the water outlet hole 125 may be formed at a position lower than the lower end 31b of the water outlet 31 . That is, as shown, it is preferable that the height of the lower end 125a of the water outlet 125 is lower than that of the bottom surface 31a of the water outlet 31. This is to prevent liquid such as water from accumulating on the bottom surface 31a of the outlet 31 by allowing water inside the outlet 31 to flow into the body 10 through the outlet hole 125.

In addition, the lower end 125a of at least one of the plurality of water outlet holes 125 may be formed at a position lower than the lower end 31a of the water outlet 31. For example, the lower end 31a of the outlet 31 is formed to gradually decrease in height toward the center, and at the same time, the lower end 31a of the outlet 31 gradually increases toward the inner end 31b (right end in FIG. 20). It is formed inclined so that is lowered. Therefore, in this case, it is preferable that the height of the lower end 125a of the middle (in FIG. 20) water outlet hole 125' among the plurality of water outlet holes 125 is formed lower than the height of the lowermost end 31b of the water outlet 31. .

In this case, liquid such as water collected on the lowest bottom surfaces 31a and 31b of the water outlet 31 can flow into the body 10 through the water outlet hole 125' in the middle.

23 shows another embodiment of the water outlet hole 125.

As shown therein, the plurality of water outlet holes 125 may be formed in a circular or slit shape. As shown in the example, the water outlet hole 125b at the upper or upper end is formed to have a slit shape so that the left and right lengths are longer than the vertical height, and the water outlet hole 125c at the lower or lower end is formed in a circular shape. It can be.

Also, the size of the relatively upper water outlet hole 125b may be formed to be larger than the size of the lower water outlet hole 125c. As described above, this is to ensure that steam generated inside the body 10 moves upward and is well discharged to the outside through the upper half of the water outlet hole 125.

As such, the water outlet hole 125 is made up of a plurality of water outlet holes 125, and a slit-shaped water outlet hole 125b is positioned on the upper side, and a circular water outlet hole 125c is positioned on the lower side. Also, the size (area) of the slit-shaped water outlet hole 125b may be larger than the size (area) of the circular water outlet hole 125c.

Hereinafter, the operation of the electric kettle according to the present invention having the above configuration will be described with reference to the drawings.

First, in order to use the electric kettle 1 according to the present invention, the user inserts a power line (not shown) connected to the base 60 into an outlet so that power is connected.

In this state, water or content is put into the heating space 101 inside the body 10, and the body 10 is placed on the base 60.

When the body 10 is seated on the base 60, the upper power module 55 and the lower power module 64 contact each other so that power can be supplied from the base 60 to the body 10 do.

Next, the user can start heating the heater 54 by manipulating the pressing part of the handle 40 . At this time, the user can check the set temperature through the display unit, and can operate the heating start of the water accommodated in the heating space 101 by manipulation. That is, by pressing the on/off button to control the operation of the heater 54, the user can control heating and stopping of water.

In addition, it will be possible to set the temperature and instruct the operation by manipulating buttons or the like. And, if necessary, two or more operation units (press units) may be provided.

The operation of the heater 54 can be started by this operation, and the water accommodated in the heating space 101 can be heated by the heat of the heater 54 .

When the water inside the heating space 101 reaches a set temperature by the detection of the temperature sensor assembly 53, the heater 54 may stop operating, and thus the electric kettle 1 operates. will complete

When the operation of the electric kettle 1 is completed, the user can hold the handle 40 and lift the body 10 to separate it from the base 60, and tilt the electric kettle 1 to pour the heated water. It can be poured through the water outlet assembly 30 .

The electric kettle 1 can reduce or block heat conduction due to the dual structure of the body 10 when the water is completely heated. Therefore, even if the user comes into contact with the outer surface of the body 10, it is not excessively hot, so safety in use can be ensured, and the temperature of the heated water can be maintained for a long period of time even when the heater 54 is not operating. can

On the other hand, as described above, the water extraction assembly 30 is formed on the upper end of the body 10 to protrude outward. That is, the water outlet assembly 30 in the form of a rostrum is formed to protrude outside the body 10 to guide the discharge of water inside the body 10 .

In addition, various sealing members such as a packing member 33 are further provided in the water extraction assembly 30 to block water leakage through the periphery of the water extraction assembly 30 . Therefore, even when the user tilts the electric kettle to fill the water, water leakage through the top of the body 10 or around the water outlet assembly 30 is prevented.

In addition, in the above embodiment, the case where the shape or size of the water outlet hole 125 is varied is exemplified, and the size and structure of the water outlet hole 125 prevents steam discharge or water accumulation.

Specifically, when a plurality of small-sized circular water outlet holes 125 are provided, the water outlet 31 and the water outlet hole 125 may have a spitting shape. That is, when boiling water after closing the lid 20 on the body 10, a temperature difference between the inside and outside of the body 10 occurs, so that the steam generated inside the body 10 flows through the water outlet 125 ) and exits to the outside through the outlet 31. At this time, since there is a temperature difference between the water outlet 31 and the inside of the body 10, steam coming out of the body 10 through the water outlet hole 125 through the water outlet 31 is turned into water by the cold air outside. It changes. As a result, the phenomenon of spitting out water by the residues on the outside (outlet) occurs.

In order to solve this problem, in the present invention, a slope is added to the bottom surface 31a of the water outlet 31 so that water can flow well, and the lower end 125a of the water outlet hole 125 is the bottom surface 31a of the water outlet 31 ) so that the water inside the outlet 31 can flow into the inside of the body 10 well, so that the water is not discharged to the outside.

In addition, the shape of the plurality of water outlet holes 125 has a larger number or area of the water outlet holes 125 at the upper part than the number or area of the water outlet holes 125 at the bottom, so that steam inside the body 10 is relatively It is discharged to the outside of the body 10 through the water outlet hole 125 formed on the upper side, and the external atmosphere (atmospheric pressure) applies pressure so that the water at the bottom of the water outlet 31 enters the inside of the body 10, spitting out is prevented.
