  Here, in the electric kettle, a grip handle portion extending from the top to the bottom is disposed on the outer peripheral surface on the rear side of the device body. For example, the handle portion is easy to grip. For various reasons such as pursuit of design, pursuit of design, and arrangement of some device in the handle part, it is considered to form a substantially flat outer surface on the outer side (outer side) of the handle part. .

  In such an electric kettle having a substantially flat outer surface formed on the outside of the handle portion, when the device body of the electric kettle is accidentally overturned, generally, the substantially entire bottom surface of the device body is a desk or the like. From the upright state in contact with the top surface, the entire bottom surface of the device main body is separated from the top surface of the desk or the like, and the substantially entire outer peripheral surface of the device body is in a falling state in contact with the top surface of the desk or the like. Very rarely, the device body may be tilted upright when shifting from the upright state to the overturned state. This tilted upright state means that when transitioning from an upright state to a fallen state, the substantially planar outer surface formed on the outside of the handle portion and the outer peripheral surface of the device body are simultaneously in contact with the upper surface of the desk, This is a state where the device main body is stationary in a posture inclined by a predetermined angle with respect to the upper surface of the desk. In this tilted upright state, the outer surface of the handle part and the top surface of the desk are almost in line contact, and the outer peripheral surface of the bottomed cylindrical device body and the top surface of the desk are in point contact, The device body is stationary in the tilted upright state (see FIG. 5 of the present application). Note that in this tilted upright state, the substantially line contact between the outer surface of the handle portion and the top surface of the desk may be substantially contact at two points on both ends of the line segment of the line contact. In some cases, two points on both ends of the outer surface of the handle part and one point of the outer peripheral surface of the bottomed cylindrical device main body and the upper surface of the desk are in contact at three points.

  If the electric kettle device main body is in an inclined upright state, for example, as shown in FIG. 5A, the device main body is inclined at a predetermined angle toward the handle portion side with respect to the upper surface of the desk. The cone of the fall stop water valve moves slightly on the inclined surface of the valve seat, but does not move sufficiently to close the communication port formed on the upper side of the valve seat. In such a case, there is a possibility that the hot water contained in the device main body is discharged to the outside through the steam port formed in the upper part of the lid, and there is room for improvement.

  The present invention pays attention to such conventional problems, and its purpose is to reliably move the hand-poured device from the upright state to the overturned state even when the hand-poured device is accidentally turned over. Another object of the present invention is to provide a hand-poured device that can reliably prevent hot water from being discharged to the outside through a steam port when the hand-poured device is inclined upright.

In order to achieve the above object, a hand-poured apparatus according to the present invention includes a bottomed cylindrical apparatus main body for storing hot water therein, a lid body capable of opening and closing an upper opening of the apparatus main body, A steam discharge mechanism for discharging the steam in the device main body to the outside through a steam port disposed in the upper portion; and a gripping mechanism extending from the upper side to the lower side on the outer peripheral surface of the rear side of the device main body. A hand-poured device provided with a handle and a tip-off water valve for preventing hot water in the device body from flowing out to the outside through the steam port when the device body is overturned. And the characteristic composition is
The handle portion includes a substantially planar outer surface outside the handle portion, and a lower outer peripheral surface on the rear side of the device main body on the lower side of the handle portion is on a radially outer side of the device main body. A protruding portion is formed, and the protruding portion is within the width of the handle portion in the left-right direction when viewed from the front-rear direction of the device body, and either one of the left-right direction with respect to the center line of the width The device main body is more than a virtual straight line connecting the outer surface of the handle portion and the lower outer peripheral surface of the device main body in a side view of the handle portion. It is in the point set to the protrusion height which protrudes to the radial direction outer side.

  Here, the hand-poured device basically includes a bottomed cylindrical device main body, and a grip handle portion extending from the upper side to the lower side on the outer peripheral surface of the rear side of the device main body includes Since the outer surface of the handle is provided with a substantially flat outer surface, if the device body of a hand-poured device is accidentally overturned, the bottom surface of the device body is placed parallel to the top surface of the desk, for example. When the device body falls from the upright state and the device body falls to the fall state in which the outer peripheral surface, which is the side surface of the device body, is parallel to the top surface of the desk, the device body is in an inclined upright state. May end up. This tilted upright state means that when transitioning from an upright state to a fallen state, the substantially planar outer surface formed on the outside of the handle portion and the outer peripheral surface of the device body are simultaneously in contact with the upper surface of the desk, This is a state where the device main body is stationary in a posture inclined by a predetermined angle with respect to the upper surface of the desk. In this tilted upright state, the outer surface of the handle part and the top surface of the desk are almost in line contact, and the outer peripheral surface of the bottomed cylindrical device body and the top surface of the desk are in point contact, The device body is stationary in the tilted upright state (see FIG. 5 of the present application). Note that in this tilted upright state, the substantially line contact between the outer surface of the handle portion and the top surface of the desk may be substantially contact at two points on both ends of the line segment of the line contact. In some cases, two points on both ends of the outer surface of the handle part and one point of the outer peripheral surface of the bottomed cylindrical device body and the upper surface of the desk may be contacted at three points (the same applies hereinafter). ).

Even in such a situation, according to the above-described characteristic configuration, when the device body of the hand-poured device accidentally falls down and shifts from the upright state (see FIG. 2 of the present application) to the overturned state (see FIG. 6 of the present application). Even when there is a possibility of standing still in an inclined upright state, the outer surface of the handle portion and the upper surface of the desk are in almost line contact, but at least the outer peripheral surface of the bottomed cylindrical device body is the outer peripheral surface. Among these, the protrusion formed on the lower outer peripheral surface and protruding outward in the radial direction makes point contact with the upper surface of the desk (see FIG. 4 of the present application).
In this case, the protrusion is disposed within the width of the handle portion in the left-right direction as viewed in the front-rear direction of the device body and at a position that is biased to either side of the left-right direction with respect to the center line of the width. In addition, the protrusion height of the protrusion portion protrudes radially outward from the virtual straight line connecting the outer surface of the handle portion and the lower outer peripheral surface of the device body in a side view of the handle portion. Therefore, when the outer surface of the handle portion and the upper surface of the desk are in substantially line contact, the protruding portion inevitably makes point contact with the upper surface of the desk. In addition, this point contact point is a position deviated from the center line of the axis of the device main body and the width of the handle portion in the front-rear direction of the device main body, and is also deviated from the center of gravity of the device main body. Since the drag force acts on the device main body through the protruding portion, a rotational moment around the axis of the bottomed cylindrical device main body is applied. Therefore, for example, the device main body rotates in the rotation direction indicated by the arrow in FIG. 4B, and the apparatus main body surely shifts from the upright state to the overturned state without being stationary in the tilted upright state.
Therefore, even if the electric kettle is accidentally turned over, the electric kettle is reliably shifted from the upright state to the overturned state, and the electric kettle is inclined upright, and hot water is discharged to the outside through the steam port. Can be surely prevented.

  A further characteristic configuration of the hand-poured apparatus according to the present invention is provided with a lower diameter-reducing outer peripheral surface that decreases in diameter as the lower outer peripheral surface of the apparatus main body goes downward, and the protruding portion is the lower diameter-reduced outer peripheral surface. It is in the point arrange | positioned.

  According to the above-described characteristic configuration, in the side view of the handle portion, the downward contraction that is one of the places through which a virtual straight line connecting the outer surface of the handle portion and the lower outer peripheral surface (lower reduced outer peripheral surface) of the device body passes. Since the projecting portion can be provided on the outer peripheral surface of the diameter, the projecting height of the projecting portion can be made relatively low, and the device main body provided with the projecting portion can be manufactured easily and at low cost.

  According to a further characteristic configuration of the hand-poured apparatus according to the present invention, the protrusion height of the protrusion disposed on the lower diameter-reduced outer peripheral surface extends from the bottom surface of the apparatus main body in a side view of the handle part. It is set to a protruding height that is positioned on the lower diameter-reduced outer peripheral surface side of the device body from the virtual extension line that is issued and the virtual extension line that passes through the outer peripheral surface end of the device body that is orthogonal to the virtual extension line. There is in point.

  According to the above characteristic configuration, the tip of the projecting portion formed on the lower diameter-reduced outer peripheral surface is orthogonal to the virtual extension line extending from the bottom surface of the device main body and the virtual extension line in a side view of the handle portion. Since it is located on the lower diameter outer peripheral surface side of the device main body from the virtual extension line passing through the end portion of the outer peripheral surface of the device main body, it is possible to provide a protrusion so as to be relatively inconspicuous, and the appearance is not impaired. The protrusion does not interfere with the use of the electric kettle.

  According to a further feature of the hand-poured apparatus according to the present invention, a flat plate-like substrate for controlling the heating means for heating the hot water in the apparatus main body is provided in the handle part, the outer surface of the handle part. It is in the point arrange | positioned in parallel facing.

  According to the above characteristic configuration, since the handle portion has a shape having a substantially planar outer surface outside the handle portion, a flat plate-like substrate is securely arranged in the handle portion in a state of facing the outer surface. In addition, when the operation sensing unit for operation is provided on the substrate and the operation sensing unit is pressed by the operation switch provided on the outer surface of the handle unit, the structure can be freely changed. The degree can be improved.

  Next, based on FIG. 2 to FIG. 6, the operation when the electric kettle falls down accidentally is the case of the electric kettle provided with the protruding portion 50 according to the embodiment of the present invention, and the protruding portion 50 is used as a comparative example. The case of an electric kettle that is not provided will be described in comparison.

[Comparative Example]
When the device main body 2 of the electric kettle according to the comparative example that does not include the projecting portion 50 is mistakenly turned to the handle portion 8 side, the bottom surface of the device main body 2 is placed upright, for example, parallel to the upper surface of the desk At the time of transition from the state (see FIGS. 2 and 3) to the fall state (see FIG. 6) in which the outer peripheral surface 2a, which is the side surface of the device body 2, is parallel to the top surface of the desk, the device body 2 is tilted correctly. There is a case where the robot stands still in a standing state (see FIG. 5). The tilted upright state means that the substantially flat outer surface 8a formed on the outer side of the handle portion 8 and the lower diameter-reduced outer peripheral surface 2b of the device body 2 are simultaneously set at the time of transition from the upright state to the falling state. The apparatus main body 2 is in a stationary state in a posture inclined by a predetermined angle (about 30 degrees in this comparative example) with respect to the upper surface of the desk. In this tilted upright state, the outer surface 8a of the handle portion 8 and the upper surface of the desk are substantially in line contact, and the lower diameter-reduced outer peripheral surface 2b of the bottomed cylindrical device body 2 and the upper surface of the desk are points. Since it is in contact, the device main body 2 is stationary in an inclined upright state (see FIG. 5). In FIG. 5B, the handle portion 8 is indicated by a virtual line for easy understanding.

  When the device main body 2 is tilted upright as described above, the device main body 2 is stationary in a posture inclined at a predetermined angle toward the handle portion 8 with respect to the upper surface of the desk, as shown in FIG. In addition, the cone 24 of the overturn stop valve Q moves slightly on the inclined surface of the valve seat 25 but does not move sufficiently to close the communication ports 26A and 26B formed on the upper side of the valve seat 25. End up. In such a case, the hot water W accommodated in the apparatus main body 2 will be discharged | emitted outside via the steam port 18 formed in the upper part of the cover body 5. FIG.

〔Example〕
On the other hand, when the device main body 2 of the electric kettle according to the embodiment of the present application provided with the protruding portion 50 is accidentally turned down to the handle portion 8 side, it falls from the upright state (see FIG. 2) to the overturned state (see FIG. 6). Even when there is a possibility of standing still in an inclined upright state, the outer surface 8a of the handle portion 8 and the upper surface of the desk are almost in line contact with each other, but the lower diameter of the bottomed cylindrical device body 2 is reduced. In the outer peripheral surface 2b, at least the projecting portion 50 formed on the lower diameter-reduced outer peripheral surface 2b and projecting radially outward is in point contact with the upper surface of the desk (see FIG. 4). In FIG. 4B, the handle portion 8 is indicated by a virtual line for easy understanding.

  In this case, the protrusion 50 is within the width (2D) in the left-right direction of the handle portion 8 and on either side in the left-right direction with respect to the center line L4 of the width when the device body 2 is viewed in the front-rear direction. Further, the protrusion 50 is disposed at a position deviated by the distance P, and the protrusion 50 has a protrusion height between the outer surface 8a of the handle portion 8 and the lower diameter-reduced outer peripheral surface 2b of the device body 2 in a side view. Since the protrusion height is set so as to protrude outward in the radial direction of the device main body 2 with respect to the connecting virtual straight line L1, even when the outer surface 8a of the handle portion 8 and the upper surface of the desk are substantially in line contact, it is inevitable. Further, the protrusion 50 also makes point contact with the upper surface of the desk. In addition, this point contact location is deviated from the axis X of the device main body 2 and the center line L4 of the width of the handle portion 8 in the front-rear direction of the device main body 2, and is also deviated from the center of gravity of the device main body 2. Thus, a drag force from the upper surface of the desk is applied to the device main body 2 via the protruding portion 50, so that a rotational moment around the axis X of the bottomed cylindrical device main body 2 is applied. Accordingly, the device main body 2 rotates in the rotation direction indicated by the arrow in FIG. 4B, so that the device main body 2 reliably shifts from the upright state to the overturned state without being stationary in the tilted upright state. It is possible to reliably prevent the hot water W from being discharged to the outside through the steam port 18 by the overturn stop valve Q.

  Further, in the electric kettle provided with the protruding portion 50 according to the embodiment, the virtual straight line L1 connecting the outer surface 8a of the handle portion 8 and the lower-diameter outer peripheral surface 2b of the device main body 2 passes through the handle portion 8 in a side view. Since the protruding portion 50 can be provided on the lower diameter-reduced outer peripheral surface 2b, which is one of the parts to perform, the protruding height of the protruding portion 50 can be made relatively low, and the protruding portion 50 is provided. The device body 2 can be manufactured easily and at low cost. Furthermore, the tip of the protruding portion 50 formed on the lower diameter-reduced outer peripheral surface 2b is perpendicular to the virtual extension line L2 extending from the bottom surface of the device body 2 and the virtual extension line L2 in a side view of the handle portion 8. Since it is located on the lower diameter-reduced outer peripheral surface 2b side of the device main body 2 with respect to the virtual extension line L3 passing through the end portion of the outer peripheral surface of the device main body 2, the protruding portion 50 can be provided so as to be relatively inconspicuous. There is no damage, and the protrusion 50 does not interfere with the use of the electric kettle.

  Therefore, even when the electric kettle is accidentally turned over, the electric kettle is reliably shifted from the upright state to the overturned state, the electric kettle is inclined upright, and the hot water W is discharged to the outside through the steam port 18. It was possible to provide an electric kettle that can be reliably prevented from being damaged without impairing the aesthetics, without impeding usability, and suppressing the increase in manufacturing cost as much as possible.
