Description

[Technical Field]

[0001] The present invention relates to an electric kettle. [Background technology]

[0002] Electric kettles that use electricity to boil water are known. A conventional electric kettle is described, for example, in Patent Document 1. The electric kettle in Patent Document 1 is a so-called crane-neck type electric kettle equipped with a tubular nozzle extending from near the bottom end of the container body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-026043 Summary of the Invention [Problem to be solved by the invention]

[0004] This type of electric kettle has a handle at the rear of the container body. A user grasps the handle and tilts the electric kettle forward to dispense hot water from the nozzle. For this reason, it is desirable that the handle be fixed so that it does not swing or bend relative to the container body.

[0005] In conventional electric kettles, for example, a metal handle is fixed to a metal container body by welding. However, when the handle is shaped like a bent metal plate, there is a problem that the handle is prone to bending when a user grips it.

[0006] In addition, when an electric kettle has a resin exterior cover that covers the outside of the container body, the exterior cover and the handle may be formed from a single resin part. In this case, forming the handle into a cylindrical shape can reduce the bending of the handle itself compared to handles made from a metal plate.

[0007] However, in this case, it was necessary to thicken the base of the handle to ensure its strength. Conversely, if the base of the handle were made thinner to make it easier for the user to grip, the handle would be more likely to swing relative to the exterior cover.

[0008] In addition, in a crane-type electric kettle, the nozzle becomes very hot due to the hot water. For this reason, it is possible to cover the outer surface of the nozzle with a cylindrical nozzle cover. However, in this case, it is necessary to prevent the nozzle cover from swinging relative to the outer cover.

[0009] Therefore, an object of the present invention is to provide a structure that can prevent cylindrical bodies such as a handle and a nozzle cover from swinging relative to an exterior cover. [Means for solving the problem]

[0010] The present invention is an electric kettle comprising a container body, an exterior cover that covers the container body, and a cylindrical body attached to the exterior cover, wherein the exterior cover has a first cover and a second cover, and the cylindrical body has an engagement groove at the connection point with the exterior cover, and a portion of the first cover and a portion of the second cover are inserted into the engagement groove.

[0011] According to the present invention, a portion of the first cover and a portion of the second cover are inserted into the engagement groove, which makes it possible to prevent the cylindrical body from swinging relative to the exterior cover.

[0012] It is desirable that the engagement groove be formed in an annular shape on the outer peripheral surface of the cylindrical body, and that a portion of the first cover or a portion of the second cover be engaged with the entire circumference of the engagement groove, thereby preventing the cylindrical body from swinging left and right and up and down relative to the exterior cover.

[0013] Preferably, the first cover constitutes a portion of the exterior cover on one side of the center, the second cover constitutes a portion of the exterior cover on the other side of the center, and the portion of the first cover that engages with the engagement groove and the portion of the second cover that engages with the engagement groove are symmetrical, thereby enabling balanced suppression of rocking of the cylindrical body relative to the exterior cover.

[0014] The cylindrical body is, for example, a handle that is gripped by a user, and this makes it possible to provide a handle that is suppressed from swinging relative to the exterior cover.

[0015] The electric kettle preferably further includes a metal plate inserted inside the cylindrical body, and the plate is fixed to the container body and the cylindrical body, thereby further preventing the cylindrical body from swinging relative to the container body.

[0016] Preferably, the electric kettle further includes a screw for fixing the plate to the cylindrical body, the screw being fastened to the cylindrical body from inside the cylindrical body, with a portion of the plate sandwiched between the head of the screw and the cylindrical body, thereby allowing the plate to be fixed to the cylindrical body without the head of the screw being exposed on the outer surface of the cylindrical body.

[0017] The electric kettle further includes a retaining member interposed between the head of the screw and the plate, the cylindrical body having a boss protruding inward from the inner surface of the cylindrical body and into which the screw is fastened, and the retaining member desirably has a recess into which the boss is inserted. In this way, the boss comes into contact with the retaining member, thereby suppressing bending of the handle.

[0018] Furthermore, it is desirable that the cylindrical body has an annular connecting member at a connection point with the exterior cover, and that the annular engaging groove is provided in the connecting member. By providing an annular engaging groove in one member in this way, distortion of the engaging groove can be suppressed.

[0019] The electric kettle may also include a tubular nozzle extending outward from the container body. In this case, the cylindrical body may be a nozzle cover that covers the nozzle. This prevents the nozzle cover from swinging relative to the exterior cover. [Effects of the Invention]

[0020] According to the present invention, a portion of the first cover and a portion of the second cover are inserted into the engagement groove, which makes it possible to prevent the cylindrical body from swinging relative to the exterior cover. [Brief explanation of the drawings]

[0021] [Figure 1] FIG. 1 is a perspective view of an electric kettle. [Figure 2] FIG. 1 is a side view of an electric kettle. [Figure 3] FIG. 1 is a vertical cross-sectional view of an electric kettle. [Figure 4] FIG. [Figure 5] FIG. 4 is a vertical cross-sectional view of the connection points between the container body, the exterior cover, and the handle. [Figure 6] FIG. [Figure 7] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, when the electric kettle 1 is upright, the nozzle 40 side of the electric kettle 1 will be referred to as the "front" and the handle 60 side will be referred to as the "rear." Furthermore, the direction perpendicular to the front-to-rear direction and the up-down direction will be referred to as the left-to-right direction.

[0023] <1. Overall structure of the electric kettle> Fig. 1 is a perspective view of a crane-shaped electric kettle 1 according to one embodiment of the present invention. Fig. 2 is a side view of the electric kettle 1. Fig. 3 is a longitudinal cross-sectional view of the electric kettle 1. The electric kettle 1 is an electric water heater that heats water stored inside. As shown in Figs. 1 to 3, the electric kettle 1 of this embodiment includes a container body 10, a lid 20, a heating unit 30, a nozzle 40, an exterior cover 50, a handle 60, and a nozzle cover 70.

[0024] The container body 10 is a cylindrical container with a bottom that stores water or hot water inside. The container body 10 is made of, for example, a heat-resistant synthetic resin. However, the container body 10 may also be made of a metal such as stainless steel. The container body 10 has a bottom 11 and a cylindrical side wall 12 that extends upward from the edge of the bottom 11. An insulating layer may be provided on the outside of the side wall 12 to improve heat retention.

[0025] The lid 20 is a unit that covers the opening at the top of the container body 10. The lid 20 is detachable from the upper end of the exterior cover 50, which will be described later. When the lid 20 is attached, the top of the container body 10 is covered by the lid 20. When the lid 20 is removed, the top of the container body 10 is opened, allowing the container body 10 to be refilled with water.

[0026] The heating unit 30 is a heater for heating the water in the container body 10. The heating unit 30 is disposed on the underside of the bottom 11 of the container body 10. For example, a mica heater, a sheath heater, or a print heater is used for the heating unit 30. When the electric kettle 1 is in use, power is supplied to the heating unit 30, causing the heating unit 30 to generate heat. This heats the water in the container body 10 and turns it into hot water.

[0027] The nozzle 40 is a tubular part for pouring hot water from the container body 10. The nozzle 40 is formed from a metal such as stainless steel. The container body 10 has a connection port 13 on the front surface near the lower end of the side wall 12. The connection port 13 is a circular hole that penetrates the side wall 12 in the front-to-rear direction. The nozzle 40 is attached to the connection port 13. The nozzle 40 extends outward from the connection port 13. More specifically, the nozzle 40 extends forward and upward from the connection port 13 in a roughly S-shape. The tip of the nozzle 40 is a spout 41 for pouring hot water to the outside. The spout 41 is located above the upper end of the container body 10.

[0028] The exterior cover 50 is a cover that covers the outer surface of the container body 10. The exterior cover 50 is formed, for example, from a heat-resistant synthetic resin. As shown in FIGS. 1 to 3, the exterior cover 50 has a cylindrical outer shape that gradually decreases in diameter toward the top. The container body 10 is housed inside the exterior cover 50.

[0029] The handle 60 is a grip that the user holds when lifting the electric kettle 1. The handle 60 is made of synthetic resin. The handle 60 extends rearward from the upper end of the rear part of the exterior cover 50. That is, the handle 60 and the nozzle 40 are located on opposite sides of the central axis A of the container body 10. The handle 60 of this embodiment extends horizontally rearward and then extends diagonally downward and rearward. The handle 60 is cylindrical and has an internal cavity. A switch (not shown) for switching on / off the power supply to the heating unit 30 is provided on the outer surface of the handle 60.

[0030] The nozzle cover 70 is a cylindrical part that covers the outer surface of the nozzle 40. The nozzle cover 70 is made of synthetic resin. The nozzle cover 70 extends in a generally S-shape from near the lower end of the front surface of the exterior cover 50 along the outer surface of the nozzle 40. Providing the nozzle cover 70 prevents the user from directly touching the nozzle 40, which is at a high temperature.

[0031] When using the electric kettle 1, the user first removes the lid 20 and pours water into the container body 10. Then, the user attaches the lid 20 and places the electric kettle 1 on the power supply stand 90, which is indicated by the imaginary line (two-dot chain line) in FIG. 2. The user then switches the switch from OFF to ON. This supplies power to the heating unit 30, causing the heating unit 30 to generate heat. This heats the water in the container body 10. The user then grasps the handle 60, lifts the electric kettle 1, and tilts it forward. This causes the hot water in the container body 10 to flow through the nozzle 40 and pour from the spout 41 into an external container (such as a teacup or cup).

[0032] <2. Handle mounting structure> The handle 60 described above is an example of the "cylindrical body" of the present invention. The structure for attaching the handle 60 to the container body 10 and the exterior cover 50 will be described below. Fig. 4 is an exploded perspective view of the electric kettle 1. Fig. 5 is a vertical cross-sectional view of the connection points between the container body 10 and the exterior cover 50 and the handle 60.

[0033] As shown in FIG. 4, the exterior cover 50 has a first cover 51 and a second cover 52. The first cover 51 is a component that configures the portion of the exterior cover 50 to the right of the center in the left-right direction. The first cover 51 is fixed to the right side surface of the container body 10 with screws. The second cover 52 is a component that configures the portion of the exterior cover 50 to the left of the center in the left-right direction. The second cover 52 is fixed to the left side surface of the container body 10 with screws.

[0034] When the first cover 51 and the second cover 52 are fixed to the container body 10, the left end surface of the first cover 51 and the right end surface of the second cover 52 come into contact with each other. This forms the cylindrical exterior cover 50.

[0035] 4 and 5, the handle 60 has a lower member 61, an upper member 62, and a connecting member 63. The lower member 61 is a semi-cylindrical part that forms the lower surface of the handle 60. The upper member 62 is a semi-cylindrical part that forms the upper surface of the handle 60. The lower member 61 is fixed to the upper member 62 with two screws 66.

[0036] The connecting member 63 is an annular member provided at the connection point with the exterior cover 50. The shape of the connecting member 63 is a substantially circular ring centered on an imaginary line extending in the front-to-rear direction. The connecting member 63 is fixed to the upper member 62 with screws. However, the connecting member 63 may also be fixed to the lower member 61. The rear end surface of the connecting member 63 contacts the front end surface of the lower member 61 and the front end surface of the upper member 62.

[0037] 4 and 5, the electric kettle 1 of this embodiment includes a generally U-shaped plate 80. The plate 80 is a component for fixing the handle 60 to the container body 10. The plate 80 is made of a metal such as iron. The plate 80 has a shape in which the front and rear portions of a horizontal band-shaped metal plate extending in the front-to-rear direction are bent downward.

[0038] The horizontal portion and rear portion of the plate 80 are inserted inside the handle 60. The horizontal portion of the plate 80 is then fixed to the lower member 61 of the handle 60 with screws. The rear portion of the plate 80 contacts the inner surface of the lower member 61. The front portion of the plate 80 is also fixed to the rear portion of the container body 10 with screws. In this way, the handle 60 is fixed to the container body 10 via the plate 80.

[0039] The plate 80 has a sufficient width in the left-right direction, and therefore does not easily bend in the left-right direction. Therefore, by fixing the handle 60 to the container body 10 via the plate 80 as described above, it is possible to prevent the handle 60 from swinging in the left-right direction relative to the container body 10. However, the plate 80 is more likely to bend in the up-down direction, where it is thinner, than in the left-right direction. For this reason, it is preferable to not only fix the handle 60 with the plate 80, but also to further prevent the handle 60 from swinging in the up-down direction relative to the container body 10.

[0040] Therefore, in this electric kettle 1, the handle 60 has an engagement groove 64. The engagement groove 64 is a recess formed at the connection point of the handle 60 with the exterior cover 50. Figure 6 is a side view of the handle 60. As shown in Figure 6, in this embodiment, the annular engagement groove 64 is formed on the outer circumferential surface of the connecting member 63.

[0041] Meanwhile, as shown in FIG. 4 , the first cover 51 and the second cover 52 each have a semicircular cutout 53. When assembling the electric kettle 1, the connecting member 63 is sandwiched between the cutout 53 of the first cover 51 and the cutout 53 of the second cover 52. The edges of the cutouts 53 of the first cover 51 and the second cover 52 are inserted into the engagement groove 64. This limits the position of the connecting member 63 in the front-to-rear direction relative to the exterior cover 50. This also prevents the connecting member 63 from tilting relative to the exterior cover 50. As a result, it is possible to sufficiently prevent the handle 60 from swinging left and right and up and down relative to the exterior cover 50.

[0042] In particular, in this embodiment, the engagement groove 64 is formed in an annular shape on the outer peripheral surface of the handle 60. The edges of the notches 53 of the first cover 51 and the second cover 52 are engaged with the entire circumference of the engagement groove 64. This makes it possible to more sufficiently prevent the handle 60 from swinging left and right and up and down relative to the exterior cover 50.

[0043] In this embodiment, the portion of the first cover 51 that engages with the engaging groove 64 and the portion of the second cover 52 that engages with the engaging groove 64 are symmetrical (bilaterally symmetrical), which allows for more balanced suppression of swinging of the handle 60 relative to the exterior cover 50.

[0044] Furthermore, in this embodiment, the annular engagement groove 64 is provided on the outer surface of the annular connecting member 63, rather than on the outer surfaces of the lower member 61 and the upper member 62. By providing the annular engagement groove 64 on one member in this way, distortion of the engagement groove 64 itself can be suppressed. Therefore, the handle 60 can be positioned with respect to the exterior cover 50 with greater precision.

[0045] 5, the lower member 61 has a boss 65 that protrudes toward the inside of the handle 60. The boss 65 protrudes upward from a horizontally extending portion of the lower member 61. The boss 65 is inserted into a through-hole provided in the plate 80.

[0046] A screw hole is formed in the boss 65. The screw 81 is fastened into the screw hole in the boss 65 from inside the handle 60. A part of the plate 80 is sandwiched between the head of the screw 81 and the lower member 61. This allows the plate 80 to be fixed to the handle 60. The head of the screw 81 is housed inside the cylindrical handle 60. Therefore, the head of the screw 81 is not exposed on the outer surface of the handle 60.

[0047] 4 and 5, the electric kettle 1 of this embodiment further includes a retaining member 82. The retaining member 82 is made of, for example, synthetic resin. The retaining member 82 is interposed between the plate 80 and the boss 65 and the head of the screw 81. The retaining member 82 is fixed to the upper surface of the plate 80 by a screw 83. Furthermore, by fastening the screw 81 to the boss 65, the retaining member 82 and the horizontal portion of the plate 80 are fixed to the lower member 61.

[0048] A recess 821 is provided on the lower surface of the retaining member 82. The upper end of the boss 65 is inserted into the recess 821. This allows the plate 80 and the retaining member 82 to be positioned accurately with respect to the lower member 61. Furthermore, even if a force is applied in a direction that bends the handle 60 when the user grips the handle 60, the outer surface near the upper end of the boss 65 comes into contact with the inner surface of the recess 821. This further prevents the handle 60 from bending.

[0049] When assembling and attaching the handle 60, first, the plate 80 and the pressing member 82 are fixed to the lower member 61 with screws 81. Next, the upper member 62 is fixed to the lower member 61 with two screws 66. Furthermore, the connecting member 63 is fixed to the upper member 62 with screws.

[0050] Next, the plate 80 is fixed to the rear of the container body 10 with screws. After that, the first cover 51 and the second cover 52 are each fixed to the container body 10. At this time, the connecting member 63 is sandwiched between the notch 53 of the first cover 51 and the notch 53 of the second cover 52. Then, the arc-shaped edges of the notches 53 of the first cover 51 and the second cover 52 are inserted into the engagement groove 64 of the connecting member 63. This makes it possible to prevent the handle 60 from swinging relative to the exterior cover 50.

[0051] <3. Nozzle cover mounting structure> The nozzle cover 70 described above is also an example of the "cylindrical body" of the present invention. The structure for attaching the nozzle cover 70 to the exterior cover 50 will be described below. Figure 7 is an exploded perspective view of the electric kettle 1.

[0052] 7, the nozzle cover 70 has an engagement groove 71. The engagement groove 71 is a recess formed in the nozzle cover 70 at a location where the nozzle cover 70 is connected to the exterior cover 50. The engagement groove 71 is formed in an annular shape on the outer peripheral surface of the rear end portion of the nozzle cover 70.

[0053] Meanwhile, as shown in FIG. 7 , the first cover 51 and the second cover 52 each have a semicircular cutout 54. When assembling the electric kettle 1, the rear end of the nozzle cover 70 is sandwiched between the cutout 54 of the first cover 51 and the cutout 54 of the second cover 52. The edges of the cutouts 54 of the first cover 51 and the second cover 52 are inserted into the engagement grooves 71. This limits the position of the nozzle cover 70 in the front-to-rear direction relative to the exterior cover 50. This also prevents the nozzle cover 70 from tilting relative to the exterior cover 50. As a result, it is possible to prevent the nozzle cover 70 from swinging left and right and up and down relative to the exterior cover 50.

[0054] Furthermore, the provision of the engagement groove 71 can prevent water from entering the interior of the exterior cover 50 from the connection point between the nozzle cover 70 and the exterior cover 50. Therefore, water can be prevented from entering electrical components such as the heating unit 30 inside the exterior cover 50.

[0055] In particular, in this embodiment, the engagement groove 71 is formed in an annular shape on the outer peripheral surface of the nozzle cover 70. The edges of the notches 54 of the first cover 51 and the second cover 52 are inserted into the engagement groove 71 along the entire circumference. This more sufficiently prevents the handle 60 from swinging left and right and up and down relative to the exterior cover 50.

[0056] In this embodiment, the portion of the first cover 51 that is inserted into the engagement groove 71 and the portion of the second cover 52 that is inserted into the engagement groove 71 are symmetrical (bilaterally symmetrical), which allows for more balanced suppression of swinging of the nozzle cover 70 relative to the exterior cover 50.

[0057] <4. Modifications> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

[0058] In the above embodiment, the container body 10 is made of resin. However, the container body 10 may be made of metal. In that case, the plate 80 may be fixed to the container body 10 by welding.

[0059] In the above embodiment, a crane-spout type electric kettle 1 has been described. However, the electric kettle of the present invention may be an electric kettle other than a crane-spout type. However, a crane-spout type electric kettle has a long tubular nozzle 40 at the front, which tends to put a load on the handle 60 when lifting it. For this reason, it is particularly significant to apply the present invention to a crane-spout type electric kettle 1.

[0060] In the above embodiment, the handle 60 has an annular connecting member 63, and the connecting member 63 is provided with the engagement groove 64. However, the handle 60 does not have to have an annular connecting member 63. In that case, the engagement groove 64 may be provided on the outer surfaces of the lower member 61 and the upper member 62.

[0061] In the above embodiment, the engagement grooves 64, 71 are annular. However, the engagement grooves 64, 71 do not necessarily have to be annular. For example, the engagement grooves 64, 71 may be rectangular annular. The first cover 51 and the second cover 52 may engage only a portion of the annular engagement grooves 64, 71 rather than the entire circumference. The engagement grooves 64, 71 do not necessarily have to be continuous annularly, but may be interrupted along the way. The portion of the first cover 51 that engages with the engagement groove and the portion of the second cover 52 that engages with the engagement groove do not necessarily have to be symmetrical.

[0062] In the above embodiment, the retaining member 82 is provided between the head of the screw 81 and the plate 80. However, if the deflection of the handle 60 can be suppressed within an allowable range by other means, the retaining member 82 may be omitted.

[0063] In the above embodiment, the screws 81 for fixing the plate 80 to the lower member 61 are fastened from the inside of the handle 60. However, the screws 81 may be fastened from the outside of the handle 60.

[0064] In the above embodiment, the metal plate 80 is provided inside the handle 60. However, the electric kettle 1 does not necessarily have to include such a plate 80. In that case, the handle 60 may be fixed to the exterior cover 50 only by the engagement of the first cover 51 and the second cover 52 with the engagement grooves 64.

[0065] Furthermore, the electric kettle 1 in the above embodiment has a nozzle cover 70 that covers the nozzle 40. However, it is not essential that the electric kettle 1 has the nozzle cover 70. For example, the nozzle 40 may be made of resin, and the nozzle cover 70 may be omitted.

[0066] In the above embodiment, the liquid stored in the electric kettle 1 is water. However, the liquid stored in the electric kettle 1 may be other liquids such as tea.

[0067] The detailed shape of the electric kettle 1 may differ from that shown in the drawings of the present application. The elements appearing in the above-described embodiments and modifications may be selected as appropriate within the scope of not causing any contradiction. [Explanation of symbols]
