Description

  The present invention relates to an electric kettle that can boil hot water in a main body part that is detachably mounted on a power supply stand, and more particularly to an electric kettle in which the disturbance of hot water during pouring is reduced.

  In recent years, in order to meet the needs of users who want to quickly boil a small amount of hot water when they want to use it, electric kettles equipped with a main body that is detachably mounted on a power supply stand have been widely used.

  Such an electric kettle has a relatively small capacity of about 0.15 liters to 1.2 liters, and when water is put into a water storage part in the main body part and placed on the power source base, When the heater is energized, boiling water can be boiled in a short time of about 1 to 3 minutes. The electric kettle does not have a heat retention function like an electric kettle, and when hot water is boiled, it lifts only the main body from the power base and tilts the main body to pour hot water in a conventional kettle. Hot water can be poured into a coffee cup from the mouth.

  As such an electric kettle, safety is taken into consideration when handling boiling hot water, and when pouring hot water, it is equipped with a hot water switch that opens the passage from the inside of the main body to the spout, and hot water is used when not in use. There is known a device provided with a lid that has a function of preventing hot water and a mechanism that prevents hot water from spilling even if the main body of the electric kettle is accidentally turned over.

  As an example of an electric kettle equipped with a lid with such a safety-enhanced structure, there has been proposed one in which there is little unfilled hot water and the volume ratio of the main body is increased (see Patent Document 1). .

  As shown in FIG. 5 (b), the bottom of the inner surface of the spout 5 having a tapered bowl shape is the center line of the bottom, that is, the bottommost portion of the cross section of the V-shaped spout 5. A bowl-shaped convex portion 52 is formed. Further, two guide grooves 51 (51a, 51b) are formed so as to sandwich the convex portion 52 from both sides thereof with a line symmetrical symmetry axis.

  The guide groove 51a and the guide groove 51b are grooves each having a width of 1 mm and a depth of 0.5 mm formed at the bottom of the inner surface of the spout part 5. As shown in FIG. 5 (b), the guide groove 51a and the guide groove 51b are arranged so that the distance between the guide groove 51a and the guide groove 51b decreases toward the distal end side of the spout part 5 along the shape of the tapered spout part 5. These are arranged so as to intersect at an angle θ of about 8 degrees with respect to the center line of the bottom surface portion of the inner surface of the spout portion 5. Further, the guide groove 51a and the guide groove 52b are formed only in about half of the inner surface of the spout portion 5 on the tip side, and in the electric kettle of the present embodiment, the distance between the two guide grooves W has an interval w1 at the root end of 4.5 mm and an interval w2 at the tip end of 2 mm.

  The hook-shaped convex portion 52 formed along the center line of the bottom portion of the spout portion 5 has both a height and a width of 0.5 mm, and is located at an intermediate portion between the two guide grooves 51a and 51b. Is formed. Similarly to the guide groove 51, the convex portion 52 is also formed in an approximately half region on the tip side of the spout portion 5. The end position on the base side of the convex portion 52 coincides with the position on the base side end portion of the guide groove 51, but in the electric kettle of the present embodiment, the end portion on the tip side of the convex portion 52 is the guide groove 51. It does not reach the tip of the spout portion 5 like the end portion on the tip side, and is formed up to a portion retreated about 3 mm from the tip.

  In the electric kettle of the present embodiment, since the two guide grooves 51a and 51b and the convex portion 52 are formed on the bottom surface portion of the inner surface of the spout portion 5, the flow of hot water can be controlled during hot water supply. This will be described with reference to FIG.

  FIG. 6A shows a hot water flow 100 in a state where the amount of hot water poured from the spout portion 5 is relatively large. As shown in FIG. 6 (a), when the amount of hot water flowing through the spout portion 5 is relatively large, the hot water is straddled across both side surfaces of the inner surface of the spout portion 5. Flowing. At this time, since both end portions of the hot water flow 100 or portions close to the both ends are applied to the guide grooves 51 (51a, 51b) formed on the inner surface of the spout portion 5, both end portions of the hot water flow 100 are guide grooves. 51 can regulate. As described with reference to FIGS. 5 (a) and 5 (b), the two guide grooves 51a and 51b are formed so that the distance between the guide grooves 51a and 51b is narrow at the tip end side of the spout portion 5. The hot water flow 100 in the mouth part 5 can be collected along the guide groove 51 on the center side of the spout part 5. Therefore, even when the amount of hot water is large, it is possible to effectively prevent the hot water from being disturbed and “running”.

  When the amount of hot water flowing through the spout portion 5 is relatively small, the hot water flow 200 flows only near the central portion of the bottom surface portion of the inner surface of the spout portion 5 as shown in FIG. Will flow. In this case, since the amount of hot water is small, the narrow hot water flow 200 is directed toward the tip side of the spout portion 5 along the bowl-shaped convex portion 52. Thus, when the amount of hot water flowing through the spout portion 5 is small, the inner surface of the spout portion 5 having a substantially V-shaped cross section is used rather than restricting both end portions of the hot water flow using grooves. By providing a tub at the bottom and keeping the flow of hot water along the tub, it can be better regulated.

  As described above, the spout portion 5 of the electric kettle according to the present embodiment has a convex portion 52 formed along the center line on the bottom surface portion of the inner surface thereof, and the formation interval becomes narrower toward the tip side. Two guide grooves 51 are provided. For this reason, regardless of the amount of hot water flowing through the spout 5, the flow can be kept firmly along the bottom surface of the inner surface of the spout 5, and the flow of hot water during pouring can be improved. Can be regulated.

  In the present embodiment, the electric kettle provided with both the two guide grooves 51 and the bowl-shaped convex portion 52 on the bottom surface portion of the inner surface of the spout portion 5 has been described as an example. This is not an essential requirement for electric kettles. Regardless of the amount of hot water flowing through the spout 5, in order to better regulate the flow of hot water, the inner surface of the spout 5 as described with reference to FIGS. 6 (a) and 6 (b). It is most preferable to provide both of the two guide grooves 51 and the bowl-shaped convex portion 52 on the bottom surface portion of the. However, the flow of hot water flowing through the spout portion can also be restricted by forming only the guide groove or the convex portion on the bottom surface portion of the inner surface of the spout portion 5.

  Further, the number of guide grooves is not limited to the two illustrated, and one or three or more guide grooves can be provided. Further, the ridge-like convex portion is not limited to one exemplified, and two or more can be formed. In addition, due to the basic restriction that the liquid flows, the spout portion 5 is not limited to the V-shaped one exemplified in the cross section, but has a U-shape, a semicircular shape, or the like as a whole. It can be considered to be a “butterfly”. For this reason, it is thought that it is preferable to arrange | position the guide groove or convex part formed in the bottom face part of the inner surface of a spout part so that it may become line-symmetrical about the centerline of a spout part as a symmetry axis. Therefore, when the number of guide grooves or protrusions to be formed is an even number, they are arranged symmetrically with predetermined intervals on both sides with respect to the center line of the inner surface bottom surface portion of the spout portion. In the case of an odd number, it is more preferable that one is arranged on the center line and the other is arranged symmetrically with a predetermined distance on both sides of the center line. Conceivable.

  In addition, the guide groove or the convex portion arranged at a predetermined interval with respect to the center line of the bottom surface portion has a root on the tip side of the spout portion like the guide grooves 51a and 51b of the present embodiment. Basically, it is considered preferable that the gap is formed to be narrower than the side interval. However, it is not an essential requirement to form the guide groove or the convex portion in such a manner that the interval on the tip side of the spout portion is smaller than the interval on the root side. Based on the shape of the bottom surface of the inner surface of the mouth, it should be appropriately selected so that the flow of hot water is well regulated.

  In FIG. 7, the cross-sectional shape of the spout part 5 as parts in the electric kettle of this embodiment is shown.

  As described with reference to FIG. 5 (a), the guide groove 51 and the convex portion 52 are formed on the bottom surface portion of the inner surface of the spout portion 5 of the electric kettle according to the present embodiment in an approximately half region on the tip side. The remaining base portion is formed as a flat portion 54. The flat portion 54 is formed deeper through the step 57 than the portion on the tip side where the guide groove 51 and the convex portion 52 are formed, that is, the surface through which hot water flows is lower. Yes. In addition, the height h of the level | step difference 57 in this embodiment is 0.5 mm as an example.

  Here, the effect | action of the level | step difference 57 in the bottom face part of an inner surface in the pouring part 5 of the electric kettle of this embodiment is demonstrated.

  As indicated by arrows 300 and 310 in FIG. 8, the hot water 300 that has flowed from the base side of the spout portion 5 is once blocked by the step 57 toward the tip side, and along the step 57, The flow is shown as an arrow 310 toward the center of the bottom surface portion of the surface. The flow toward the center portion of the bottom surface portion of the spout portion 5 indicated by the arrow 310 gathers at the center line portion of the bottom surface portion having the lowest height, gets over the step 57, and moves toward the tip side of the spout portion 5. become.

  The pouring part 5 of the electric kettle according to the present embodiment has a bottom part formed by the step 57 because the two guide grooves 51 and the convex part 52 are formed on the bottom part of the inner surface on the tip side of the pouring part 5. The hot water collected at the central portion of the water is effectively poured under the influence of the guide groove 51 and the convex portion 52 and the flow is adjusted.

  In addition, as mentioned above, the spout part 5 as a part of this embodiment is formed as an integral part by resin molding. Here, in order to form the cover member 53 that covers the inner surface of the spout portion 5 on the top surface on the base side of the spout portion 5 as an integrally molded product of resin, two directions indicated by arrows 61 and 62 in FIG. It is necessary to remove the inner mold. However, a dividing line (PL) of the mold is generated at the boundary part of the inner mold divided into two parts, and a burr that cannot be completely eliminated is generated in this part. Thus, the burr | flash formed when the spout part 5 as a part is integrally molded becomes a cause which disturbs the flow of hot water, and also becomes a problem on appearance. Then, like the spout part 5 of this embodiment, by making the dividing line of this molding die into the level difference 57, it is possible to prevent the occurrence of undesired burrs and The action of collecting the flow can be given.

  Of course, it is not an essential requirement to match the formation position of the step 57 with the dividing line of the molding die, for example, when the spout portion 5 is made of a metal material or when the spout portion 53 is formed of a resin. However, when the cover member 53 is formed as a separate member instead of being integrally molded, it is the most suitable position considering only the flow of hot water regardless of the position where the cover member 53 is formed. A step 57 can be formed.

  FIG. 9 is a partially enlarged cross-sectional view showing the shape of the tip of the spout part 5 of the electric kettle of the present embodiment.

  As shown in FIG. 9, the tip of the spout portion 5 of the electric kettle of the present embodiment is a surface in which the inclination angle γ with respect to the horizontal surface A of the inner surface through which hot water flows constitutes the bottom surface of the inner surface other than the tip. Compared with the inclination angle α of B with respect to the horizontal plane A, it is formed so as to satisfy the relationship of γ <α more gently.

  Specifically, as described above with reference to FIG. 4B, in the electric kettle of the present embodiment, the inclination angle α of the bottom surface portion other than the tip portion of the inner surface of the spout portion is about 20 degrees. On the other hand, the inclination angle γ of the tip is about 5 degrees. Thus, by setting the inclination angle γ of the tip portion of the spout portion 5 to a value smaller than the inclination angle α of the portion other than the tip portion by an angle β (= α−γ, about 15 degrees), the spout portion The direction of hot water poured from the tip of 5 can be bent downward. When the inclination angle of the bottom surface portion of the inner surface of the spout portion 5 is continuously formed from the base side to the tip portion at the same angle, when the user tilts the electric kettle and pours hot water, The hot water that has been tapped may flow forward beyond your imagination. This is especially likely when there is a large amount of hot water in the electric kettle. If the hot water pops out forward than the user expects, it will spill from the coffee cup where hot water should be poured, The hot water hitting the inner wall jumps up vigorously, and the user may be burned. For this reason, like the spout part of this embodiment, the inclination angle of the bottom surface part of the inner surface of the spout part is made gentler at the tip part to cause the hot water to bend downward, so that the hot water can be used by the user. It is possible to effectively avoid jumping forward more than expected.

  The inclination angle γ of the tip portion has a difference β of 5 with respect to the inclination angle α on the root side in order to exert an action of changing the flow of hot water formed at the bottom surface of the spout portion on the root side downward. It is preferable that the degree is at least. On the other hand, the inclination angle γ of the tip portion is made too small so that the electric kettle is placed in parallel with the horizontal plane A, or so that the tip side is directed obliquely downward with respect to the horizontal plane A (γ When the user tilts the main body 1 of the electric kettle to a substantially horizontal state, as shown in FIG. 10, it is poured from the spout 5. The hot water 400 may wrap around with respect to the vertical axis D in the rear side, which is the bottom surface side of the main body 1 of the electric kettle, that is, in the direction of the right arrow 401 in FIG.

  When hot water wraps around as shown in FIG. 10, it becomes extremely difficult for the user to pour hot water into a desired position such as a coffee cup accurately. In order to prevent the hot water from wrapping around as shown in FIG. 10, it is preferable that the inclination angle γ at the tip of the inner surface of the spout portion 5 is 3 degrees or more.

  Based on the above, when the basic inclination angle α of the bottom surface portion of the inner surface of the spout portion 5 is 20 degrees as in the case of the electric kettle of the present embodiment, the inclination angle γ of the tip portion is 3 It can be considered that it is preferably in the range of from 15 degrees to 15 degrees.

  As described above, the user can pour hot water more accurately by making the inclination angle with respect to the horizontal plane at the tip of the inner surface of the spout part smaller than the inclination angle with respect to the horizontal plane of the portion other than the tip. An electric kettle can be realized. In addition, in FIG. 9, what formed the guide groove and the convex part in the inner surface of the pouring part was illustrated as a shape of the pouring part of the electric kettle of this embodiment. However, the effect of reducing the inclination angle of the tip end portion of the spout portion as compared with the root side portion described with reference to FIGS. 9 and 10 is exhibited regardless of the presence of the guide groove or the convex portion. Is. For this reason, it cannot be overemphasized that the inclination | tilt angle of the front-end | tip part of the spout part in which the guide groove or convex part is not formed in the inner surface can be formed small compared with the base side.

  Here, the effect of the back protrusion part 56 with which the spout part 5 as an electric kettle part demonstrated by this embodiment is provided is demonstrated.

  FIG. 11 is a partial enlarged cross-sectional view of the electric kettle lid 3 of the present embodiment on the side where the spout portion 5 is formed. In addition, in FIG. 11, thick hatching is put in each member of the movable part for forming the passage of hot water at the time of hot-water supply 7 and related to it so that a concrete structure may be understood easily. Yes.

  In the electric kettle of the present embodiment, when the hot water supply switch 7 is pushed down, the disc-like valve portion 15b of the hot water supply valve 15 is shown in the drawing via the extending portion 7a of the hot water supply switch 7 and the protruding portion 15a of the hot water supply valve 15. As indicated by the white arrow 32, it is pushed down to the inner container 10 side. As a result, the inner container 10 and the water pouring channel 13 are connected as a space, a hot water supply route indicated by an arrow 33 in FIG. 11 is formed, and hot water can be poured from the spout portion 5.

  On the other hand, in a state where the hot water supply switch 7 is not pushed down, the disc-shaped valve portion 15b of the hot water supply valve 15 prevents the hot water from flowing out from the spout portion 5 even when the electric kettle is tilted or overturned. Must shut off the inner container 10 and the water injection channel 13. For this reason, as shown in FIG. 11, a joining surface portion 31 is formed between the water injection channel 13 and the inner container 10 so that the surfaces contact each other in a state where the valve portion 15 b of the hot water supply valve 15 is not pushed down. .

  This joint surface portion 31 protrudes toward the center of the inner container 10 so as to cover the valve portion 15b so that the flow of hot water can be reliably stopped by contacting the valve portion 15b of the hot water supply valve 15 with each other. Is formed. On the other hand, when the hot water supply valve 15 is pushed down and the inner container 10 and the water injection path 13 are spatially continued, the joint surface portion 31 becomes a barrier to the route 33 through which hot water flows. Here, when the upper side of the joint surface portion 31 is planar such that the plate-like member protrudes into the route 32 through which hot water flows, the flow of hot water around the back side of the joint surface portion 31 is generated, and the inner container A smooth hot water flow 33 between 10 and the water injection channel 13 is not formed.

  Therefore, in the pouring part 5 of the electric kettle of the present embodiment, a rear projecting portion 56 that projects to the inner surface side of the lid 3 is formed, and the tip of the rear projecting portion 56 is made to follow the tip of the joint surface portion 31. The hot water flow 33 flowing into the water injection channel 13 beyond the joint surface portion 31 can be made smooth.

  As described above, in the electric kettle of the present invention, the flow of hot water flowing on the inner surface of the spout portion can be regulated by the guide groove or the convex portion formed on the bottom surface portion of the spout portion inner surface. In addition, it is possible to realize an electric kettle in which hot water disturbance during hot water supply is reduced and a user can pour hot water safely.

  In addition, by setting the inclination angle of the tip portion of the spout portion to a value smaller than the inclination angle of the root side portion, it is possible to control the hot water flow forward from the spout portion so as not to jump out.

  In the above embodiment, the spout portion is fixed to the upper part of the side surface of the lid body, and the spout portion is fixed to the side surface of the main body portion when the lid body is fixed to seal the opening of the main body portion of the electric kettle. The thing of the structure which protrudes from the side was illustrated. However, the electric kettle of the present invention is not limited to this configuration, and the lid that seals the opening of the main body is a single plate, and the spout is directly fixed to the side end of the main body. It can be of a configuration.

  Further, the material of the spout portion is not limited to the exemplified resin, and for example, a metal material such as stainless steel can be used.

  The electric kettle of the present invention is useful as an electric kettle in which hot water flowing out during hot water supply is less disturbed and hot water can be poured safely.
