Description

  The present invention relates to an electric hot water storage container that heats and heats the content liquid to store and use the hot water, and in particular, has a container that can be placed and heats the content liquid with a heater to perform water boiling and heat insulation. In the operation part formed by the upper surface of the projecting part where the outer periphery of the opening of the opening for supplying and discharging the content liquid at the upper end of the container is projected to the front side, an independent discharge operation member is provided. The present invention relates to an electric hot water storage container which is used for use by transmitting a pressing operation directly or indirectly to a discharge switch to operate a discharge means, discharging through the protruding portion through a discharge path having a discharge port opened downward from the protruding portion. .

  For many years, the operation part in such an electric hot water storage container is exclusively a switch operation part called a resin spring in which the operation part wall is cut to give a spring property (for example, boiling in Patent Document 2 and FIG. 5). For example, a resin sheet (see, for example, Patent Document 2 and the display sticker 38 in FIG. 5) that has a sealing property. In addition, the mainstream has a position display corresponding to the switch operation unit, a lamp display unit, a character display, etc. in addition to exhibiting the sealing performance against the cut.

  However, the size of the resin spring type switch operation unit is limited in terms of durability, etc., even if the operation position indication on the nameplate is large, the switch operation unit below it is not large, and the push-in amount is within the nameplate surface. Because it is limited by the deformation limit, it may cause a force if it is a discharge operation, and it may cause inconvenience to an operation with a strong push-in consciousness, or it may cause an excessive reaction force due to excessive operation. is there.

On the other hand, an electric hot water storage container having an independent discharge operation member to be pressed is already known (for example, Patent Document 1, Hot Water Supply Knob 13 in FIG. 2, Patent Document 2, FIG. 1, FIG. 3, FIG. 4). (Refer to the button 34 for hot water supply, and the operation member 32 of FIGS. 1 and 2 of Patent Document 3.) In this way, when an independent discharge operation member is provided to perform a pressing operation, the pressing operation surface can be made sufficiently large, and the operation amount is not limited by the in-plane deformation limit by the nameplate. Can be resolved.

  However, in order to provide an independent discharge operation member and perform a pressing operation, it is necessary to expose the discharge operation member to the operation unit independently from the nameplate. For this reason, an opening for exposing the discharge operation member is required on the operation unit wall, and in the structure in which the gap between the opening and the discharge operation member is left as it is as described in Patent Documents 2 and 3, the operation unit has If water reaches the operation part due to the fact that it is next to the upper end opening for supply and discharge of the container, it will enter the gap, not only the switch directly under the discharge operation member but also the operation part There is a possibility that a circuit board provided underneath, or a control board and electrical equipment provided in the container may be damaged. Further, in the structure in which the gap is closed by the annular rubber 14 of Patent Document 1 and FIG. 3, the number of parts and the number of assembling steps are increased, resulting in an increase in cost, and the operation frequency of the discharge operation member is increased. There is a problem in that the rubber 14 is prematurely damaged and seal breakage is likely to occur.

  Furthermore, since all of the discharge operation members disclosed in Patent Documents 1 to 3 adopt an installation structure that has an upward retaining structure and is fitted from below with respect to the opening of the operation unit wall, Even if a problem is found in the discharge operation member after assembly or a problem occurs, the discharge operation member cannot be taken out from the outside alone, and there is a problem that maintenance is difficult or impossible.

  In order to cope with these problems, the present inventors have conducted various experiments and studies, and an independent discharge operation member can be attached to and detached from the opening of the operation unit from above, and water has entered from a gap formed around the discharge operation member. In addition, the present inventors have found a technique that can be stored at least under the discharge operation member so that the electrical component is not affected without the trouble of sealing by a special seal member. However, if the ingress water is drained from the vessel opening, the temperature is often high, and the thermal isolation of the operation unit to the low heat resistance display unit is satisfied simply by isolating the electrical equipment from the ingress water. First of all, it was discovered that a special response was necessary. For example, as shown in FIG. 12, the liquid crystal display unit has spacers that seal the front and back glass substrates that store liquid crystal at a predetermined interval in the margin portion MG from the data area DA to the view area VA. This spacer is an ABS resin, and the heat resistant temperature is as low as about 60 ° C., and in a high temperature environment higher than that, it deforms and affects the tilt of the liquid crystal and the arrangement of the liquid crystal molecules, causing display failure and display failure.

  The object of the present invention is based on such new knowledge, and an independent discharge operation member can be attached to and detached from the opening of the operation section wall from above, and even if water or hot water reaches both sides, It is an object of the present invention to provide an electric hot water storage container which can eliminate an influence on electrical equipment with an inexpensive structure without mounting and can also eliminate a thermal influence on a low heat resistant display portion.

In order to achieve the above-mentioned object, the electric hot water storage container of the present invention has a container that can be placed, heats the content liquid with a heater, performs boiling and heat insulation, stores the hot water, and stores the stored content liquid. The operation of pressing the independent discharge operation member is directly or indirectly transmitted to the discharge switch to the operation part formed by the upper surface of the overhanging part protruding from the opening for supplying and discharging the liquid at the upper end of the container. The discharge means works, discharges through the protruding portion through the discharge path having the discharge port opened downward from the protruding portion, and the electric hot water storage container to be used is used as a basic configuration. The switch is provided with a circumferential groove surrounding an operation area for transmitting a pressing operation, and the discharge operation member is fitted from above into an opening formed by an outer peripheral wall of the circumferential groove so that the pressing operation can be performed.

In such a configuration, an independent discharge operation member can be positioned with a sufficient operation area and a pressing stroke in the operation portion formed by the upper surface of the projecting portion from the upper end opening of the container to the front side due to the basic configuration. It is easy to press on the fixed container in response to the user's desire for the discharge operation, and directly or indirectly transmits it to the discharge switch to make the discharge means work and discharge the content liquid. It can be discharged from a discharge port that opens downward from the overhanging portion and can be used. In particular, this discharge operation member is pressed in an opening to the upper surface of the operation portion formed by the outer peripheral wall of the circumferential groove provided so as to surround the operation area where the discharge operation member in the operation portion transmits the press operation to the discharge switch. In the operation part, a gap between the discharge operation member and the opening to the upper surface of the operation part formed by the outer peripheral wall of the circumferential groove is exposed, and the operation part in which the supply / drainage liquid from the upper end opening of the container tilts forward Even if a part of the water enters the gap while flowing down, the intruding water flows down into the circumferential groove and is collected at the bottom. For this reason, since the operation area for the discharge switch by the discharge operation member is higher than the bottom of the circumferential groove surrounding the discharge switch, the water collected at the bottom does not reach, and the operation of pressing the discharge operation member is discharged to the operation area. Even if there is an opening for directly transmitting to the switch or an opening by a mediating portion of a resin spring structure that mediates transmission of a pressing operation, intrusion water can be prevented from reaching the operating portion. Moreover, collected in the circumferential groove water of the bottom portion, the operation portion and the display substrate along a downward slope in the opposite of the rear, it is guided to a position outside the rear of the display board incorporated in the operation unit Since the water is drained from the drain hole located there, the display substrate is not electrically damaged. In addition, if the discharge operation member is designed so that it can be elastically attached and detached, and the assembly of the support can be disassembled from above, by using the support so that it can be pushed down into the opening formed by the circumferential groove from above, Maintenance can be performed by attaching and detaching from above alone.

Even if liquid or the like reaches and enters the gap, the intruding water is transferred into the circumferential groove and collected at the bottom. For this reason, since the operation area for the discharge switch by the discharge operation member is higher than the bottom of the circumferential groove surrounding the discharge switch, the water collected at the bottom does not reach, and the operation of pressing the discharge operation member is discharged to the operation area. Even if there is an opening for directly transmitting to the switch or an opening by a mediating portion of a resin spring structure that mediates transmission of a pressing operation, intrusion water can be prevented from reaching the operating portion. Moreover, the water collected in the circumferential groove and the water that enters the supporting member that supports the discharge operation member are discharged from the support member positioned at the lowest position inclined low toward the rear part of the bottom of the circumferential groove. a position deviated to the rear than the display board incorporated in built to operating unit, since it is drained along a predetermined path through the drain hole which forms in common with the circumferential grooves, to provide electrical damage to the display substrate There is no. In addition, if the discharge operation member is designed so that it can be elastically attached and detached, and the assembly of the support can be disassembled from above, by using the support so that it can be pushed down into the opening formed by the circumferential groove from above, Maintenance can be performed by attaching and detaching from above alone.

However, a flow rate sensor that rotates by the discharge flow may be additionally provided on the upper portion 25a of the discharge path 25. According to the flow sensor, the start and end of discharge, the discharge flow rate, the discharge amount, the remaining amount, etc. can be automatically detected. The content liquid flows out through the discharge path 25 when the container 1 is tilted forward or rolls over the rising portion 25a of the discharge path 25, specifically, at a height position exceeding the full water level in the vacuum double container 3. When the vehicle is tilted forward to prevent this, a roll-off water stop valve 40 is provided. Further, the discharge passage 25 has an inverted U-shaped unit 25b having a water stop valve 40 at the time of rollover when it is forwardly inclined and enters between the rising portion 25a and the pipe cover portion 2d covering the lower surface of the overhang portion 31. A discharge port 25d at the tip of the inverted U-shaped unit 25b is opened outward through the pipe cover portion 2d.

  On the back of the heater 11 applied to the single bottom of the vacuum double container 3, a metal heat shield 187 is provided and attached to the bottom lower surface of the outer cylinder 5 of the vacuum double container 3 by welding or the like. The mounting bracket 188 is screwed with a screw 189, and a metal backup plate 92 and a spring member (not shown) are sandwiched between the heat shield plate 187 and the heater 11, and the heater 11 is pressed against and firmly adhered to the bottom by this spring member. Yes.

  The outer case 2 has an assembly structure in which a metal body 112 is sandwiched between a resin bottom member 111 and a shoulder member 6, and an inner peripheral lower portion of the opening 12 of the vessel body 1 formed by the shoulder member 6 shown in FIG. The upper flange portion 3a of the vacuum double container 3 is placed and suspended with respect to the upward stepped portion 12a provided on the bottom, and the bottom portion of the vacuum double container 3 and the bottom member 111 are welded or the like (not shown). The exterior case 2 is integrated and separated by a connection structure connected by metal fittings and screws.

  As shown in FIG. 9, the lid 13 is hinged to a bearing 122 at the rear of the shoulder member 6 by a hinge pin 120 to open and close the opening 12 of the container 1 together with the mouth 3 b of the vacuum double container 3. Can be opened and closed to the body 1. The bearing portion 122 is provided with an opening portion 122a for receiving and bearing the hinge pin 120 provided on the lid 13 side so that it can be attached and detached, and a stopper 124 for closing the opening portion 122a by the urging force of the spring 123. Then, the hinge pin 120 can be taken in and out of the bearing portion 122 with the lid 13 in a state where the lid 13 is half-opened. Further, the lid 13 is made of a metal, specifically a stainless steel inner lid 126, which closes the mouth 3 b of the vacuum double container 3. A seal member 127 sandwiched between the outer periphery of the inner lid 126 is in contact with the inner periphery of the mouth portion 3b for sealing.

  Further, as shown in FIG. 9, the lid 13 is formed with a steam passage 125 for allowing the vapor from the vacuum double container 3 to escape to the outside. The lid 13 has an inner opening 125 a at a position facing the vacuum double container 3. The outer opening 125b formed on the outer surface exposed to the outside communicates with the outer opening 125b. In the middle of the steam passage 125, when the container body 1 rolls over and the liquid content enters, a safety path 125c is provided to delay the arrival to the outer opening 125b by temporarily collecting or detouring the liquid. Accordingly, it is possible to take measures such as raising the container 1 before the container 1 rolls over and the content liquid flows out through the vapor passage 125. In addition, when the container body 1 rolls over, the steam passage 125 is provided with a water stop valve 125d at the time of overturning that works by its own weight or the like so as to prevent the invading content liquid from going forward. An appropriate number is provided.

  Further, the front portion of the lid 13 is provided with a lock member 21 that engages with a locking portion (not shown) on the shoulder member 6 side at the closed position of the lid 13 to lock the lid 13 in the closed position. When this is done, the spring 22 is always urged to the locked position so as to automatically engage the locking portion. Correspondingly, the lid 13 is provided with a lock release member 23 for releasing the lock by retracting the lock member 21.

  The electric pump 26 is a centrifugal pump provided at a position just below the bottom of the vacuum double container 3, and the content liquid flowing from inside the vacuum double container 3 is directed to the discharge port 25 d facing the outside of the container 1 through the discharge path 25. It is fed out and discharged from the discharge port 25d to the outside for use.

  As shown in FIG. 1, in the container body 1, an overhang part 31 is formed so as to project from the opening 12 of the shoulder member 6 of the container body 1 to the front side, and the upper surface of the overhang part 31 is an operation part 30. ing. As in the prior art, the operation unit 30 has a plurality of switch operation units 41, 42, 43 such as resin springs as shown in FIGS. 1 and 3, and a name plate 45 such as a resin sheet as shown in FIG. As shown in FIG. 7, the seals are bonded and covered in a watertight state, and the seals for the opening 44 by cutting or the like are exhibited. In addition, position indications 46 to 48 corresponding to the switch operating units 41 to 43. In addition, a lamp display unit 49 to 51, a character display 52 to 54, and the like are provided, and a liquid crystal display unit 55 is provided. Incidentally, the switch operation units 41 to 43 correspond to the position displays 46 to 48 having the character displays 52 to 54 of the heat insulation selection, re-boiling and unlocking on the nameplate 45 shown in FIG.

  A rotating seat ring 137 is fitted in the downwardly recessed portion 111a of the bottom member 111 of the outer case 2 so as to be rotatable from below, and when the body 1 is placed on a table surface or the like, It is designed to change direction by lightly rotating above.

  In the present embodiment, in particular, in the operation unit 30 as described above, an independent discharge operation member 61 as shown in FIG. 2 is provided as shown in FIGS. Alternatively, it is indirectly transmitted to the discharge switch 62 shown in FIGS. 1, 4, and 6 to operate the electric pump 26 as the discharge means, and the discharge port 25 d is opened downward from the overhang portion 31 through the overhang portion 31. FIG. 1 surrounds an operation area 63 in which a discharge operation member 61 as shown in FIGS. 1, 4 and 6 in the operation unit 30 transmits a pressing operation to the discharge switch 62 for discharging through the discharge path 25 and using it. 4, a circumferential groove 64 as shown in FIG. 4 is provided, and the discharge operation member 61 can be fitted into the opening 64b formed by the outer peripheral wall 64a of the circumferential groove 64 from above as shown in FIGS. Like to support . Such an independent discharge operation member 61 can be positioned with a sufficient operation area and a pressing stroke in the operation unit 30 formed by the upper surface of the projecting portion 31 from the opening 12 at the upper end of the container 1 to the front side. As a result, a pressing operation is easily performed on the stationary container 1 with a strength and a pressing amount corresponding to the user's desire for the discharging operation, and this is reliably transmitted directly or indirectly to the discharging switch 62 to be electrically operated. The pump 26 is operated to discharge the content liquid through the discharge path 25 from the discharge port 25d opened downward from the overhanging portion 31 and can be used.

  In particular, the discharge operation member 61 is connected to the upper surface of the operation unit 30 formed by the outer peripheral wall 64a of the peripheral groove 64 provided so as to surround the operation region 63 in which the discharge operation member 61 in the operation unit 30 transmits the pressing operation to the discharge switch 62. 4 to 6, the operation unit 30 includes a discharge operation member 61 and an opening 64 b on the upper surface of the operation unit 30 formed by the outer peripheral wall 64 a of the circumferential groove 64. Even if the gap 65 is exposed and the supply / drainage liquid or the like from the opening 12 at the upper end of the vessel 1 adjacent to the operation unit 30 reaches and enters the gap 65, the intrusion water can enter the circumferential groove 64. It is collected in the bottom 64c. For this reason, since the operation area 63 for the discharge switch 62 by the discharge operation member 61 is higher than the bottom 64c of the circumferential groove 64 surrounding the discharge switch 62, the water collected in the bottom 64c does not reach the operation area 63. Accordingly, the opening for directly transmitting the pressing operation of the discharge operation member 61 to the operation area 63 to the discharge switch 62 and the mediating portion 66 of the resin spring structure that mediates the transmission of the pressing operation as shown in FIG. 4. Even if there is an opening 67 as shown in FIG. 6, it is possible to prevent intrusion water from reaching the operation unit 30.

  As a result, the press operation corresponding to the user's desire for the discharge operation can be easily performed by the independent discharge operation member 61, so that the discomfort and dissatisfaction are not given, and the content liquid is discharged by reliably transmitting the press operation to the discharge switch 62. In addition, while ensuring convenience for use, the operation area 63 where the discharge operation member 61 in the operation unit 30 transmits the pressing operation to the discharge switch 62 is surrounded by a circumferential groove 64 having a lower portion 64c. Even if water enters from any portion of the annular gap 65 formed between the opening 64b to the operation portion 30 formed by the outer peripheral wall 64a of the peripheral groove 64 and the discharge operation member 61, the outer peripheral wall of the peripheral groove 64 64a is collected in the bottom 64c of the circumferential groove 64 and hardly reaches the operation area 63 below the discharge operation member 61 which is higher than the bottom 64c. The discharge operation of the discharge operation member 61 is discharged to this operation area 63. Even if there is any opening 67 for transmitting to the switch 62, the intrusion of water into the operation unit 30 does not increase the number of parts and the number of assembling steps when a special seal member is used, and therefore, the cost does not increase. 4, a discharge substrate 62 as shown in FIG. 4, a liquid crystal display module 68 inside the liquid crystal display 55, a display substrate 71 on which other switches and display lamps are mounted, and a vacuum double as shown in FIGS. Waterproofing for internal electrical equipment such as a control board 72 provided between the body part of the container 3 and the outer case 2 and a power supply board 73 provided between the bottom part of the vacuum double container 3 and the outer case 2 as shown in FIG. Can be planned.

  The discharge operation member 61 has substantially the same upper surface height relationship that is substantially flush with the operation unit 30, so that the operation region 63 that faces the lower side of the discharge operation member 61 in the operation unit 30 is located on the discharge operation member 61. The thickness or height direction dimension is one step lower than the upper surface of the operation unit 30, and hence lower than the arrangement surface of the switch operation units 41 to 43 of the operation unit 30, but lower than the bottom 64 c of the circumferential groove 64 surrounding it. Never become. Further, as shown in FIGS. 1, 3, and 4, a rib 30a is formed on the upper surface of the operation unit 30 so as to surround a bonding area where the nameplate 45 is bonded, so that positioning is performed at the time of bonding. .

  In addition, the discharge operation member 61 can be elastically attached / detached and assembled / disassembled from above by using the support so that the discharge operation member 61 can be pressed from the top into the opening 64b formed by the circumferential groove 64. If designed, it can be easily attached and detached from above and easily maintained.

  Further, in order to provide a low heat-resistant display unit such as the liquid crystal display module 68 provided in the liquid crystal display unit 55 of the operation unit 30, the intrusion water was hot water because it was positioned away from the circumferential groove 64 for collecting the intrusion water. Even in this case, direct heat conduction from the circumferential wall of the circumferential groove 64 is avoided, and air insulation is easily received by the distance away from the circumferential groove 64, and heat conduction through the wall of the operation unit 30 is also halfway. Since it is hard to receive by heat dissipation, the thermal influence from the hot water collected by the circumferential groove 64 can be eased, and it can prevent that durability is impaired.

  Further, the opening 64b formed by the circumferential groove 64 is slightly larger than the discharge operation member 61 as shown in FIGS. 3, 4, and 8, and is substantially similar in plan view. Thereby, the discharge operation member 61 and the opening 64b formed by the circumferential groove 64 can be smoothly pushed and returned without being rubbed against each other by the substantially uniform gap 65 between them, and the water is partially It is possible to prevent intrusion. However, it is preferable that the gap 65 be the minimum gap, so that even if water enters, the surface tension will cause the surface 65 to accumulate in the volume of the gap 65 and clog and flow down into the circumferential groove 64 or flow down. Can be suppressed in combination with further intrusion. However, if a seal member (not shown) that seals between the outer periphery of the discharge operation member 61 and the inner periphery of the opening 64b formed by the peripheral groove 64 is provided on the outer periphery of the discharge operation member 61 or the inner periphery of the opening 64b, the peripheral groove 64 is provided. The waterproofing effect against the intrusion of water into the inside is improved.

  Further, by making the discharge operation member 61 as a plate-like member as shown in FIGS. 2 and 4, if the height direction dimension is suppressed, a level difference that is lower than the upper surface of the operation portion 30 of the operation area 63 is correspondingly reduced. Even if the depth of the circumferential groove 64 is reduced, the difference in height required between the bottom portion 64c and the operation area 63 can be satisfied under the low-bulk condition, and the height of the vessel 1 is increased. This can be prevented.

  Here, the intruding water that extends slightly below the contour position that forms the gap 65 between the circumferential groove 64 and the opening 64 b to a position lower than the operation area 63 and enters through the gap 65 is operated area 63. When the draining edge 61a as illustrated by the phantom line in FIG. 4 is provided such that it is transferred to the bottom 64c of the circumferential groove 64 without causing the wetting to the side, the volume of water in the gap 65 is caused by the surface tension. Even if an attempt is made to leak from the stable clogged state to the inside of the gap 65 to cause the wetting of the back surface of the discharge operation member 61 to transfer to the operation area 63 side, the operation area is blocked by the draining edge 61a. It can be ensured that it is collected to the bottom 64c of the circumferential groove 64 without passing down to 63 and getting wet to the operation area 63 side.

  In addition, a mediator 66 having a resin spring structure that transmits the pressing of the discharge operation member 61 described above to the discharge switch 62 is provided in the operation area 63 to mediate transmission of the press operation of the discharge operation member 61 to the discharge switch 62. As a result, this embodiment is realized by avoiding a bulky structure that is disadvantageous for molding the discharge operation member 61 such that the discharge operation member 61 enters the inside of the wall of the operation unit 30, and the mediation unit 66 has the opening 67. Even if it has a resin spring structure, it does not have to worry about the invasion of water, so that it is not necessary to attach a sealing material, and a sufficient amount of pressing operation is not impaired by the sealing material.

  Further, the bottom 64c of the circumferential groove is lowered from one side to the other as shown in FIG. 1, FIG. 4, FIG. 6, and FIG. As a result, the collected water in the circumferential groove 64 can be collected at a specific portion of the bottom 64c of the circumferential groove 64 that is lowered, so that it is prevented from being inadvertently scattered and collected on the side far from the low heat-resistant display portion. The thermal influence on the low heat resistant display portion can be further reduced. In particular, a lower drainage hole 74 is provided in the lowest part 64d of the bottom 64c of the circumferential groove 64 shown in FIGS. As a result, the drain hole 74 provided by utilizing the lowest part 64d as a specific part is drained to a place where there is no problem or few, and intrusion water always exists in the circumferential groove 64, and accordingly. Thus, it is possible to avoid the water from reaching the operation area 63 having the opening 67 depending on the handling such as tilting the container 1, and it is far from the low heat resistant display portion such as the liquid crystal display module 68. It is possible to further reduce the thermal effect on the low heat resistant display portion by gathering on the side.

  Specifically, as shown in FIG. 6 and FIG. 7, the drain hole 74 is positioned on the rear part of the water stop valve 40 at the time of rollover when the vehicle is tilted forward. It is guided so as to flow down, and when it is tilted forward, it flows down the water stop valve 40 when it rolls over. As a result, it is possible to prevent the liquid from getting wet or flowing down to other electrical equipment. For this purpose, for example, when the water is tilted forward, the drainage is transferred from the stop valve 40 at the time of rollover to the rising portion 25 a of the discharge passage 25, and between the body portion of the outer case 2 and the vacuum double container 3. It is possible to guide to the inner bottom, flow down to a position where there is no electrical equipment at the bottom, and discharge to the outside. In the present embodiment, when tilting forward, the rollover stop water valve 40 tilts the top plate 40a forward as shown in FIG. 6 and FIG. 8 is guided to the front side of the overhanging portion 31 in a direction away from the pipe so as to flow down on the pipe cover portion 2d, and the drainage that has flowed down on the pipe cover portion 2d becomes lower on the rear side of the pipe cover portion 2d, and FIG. As shown in FIG. 4, the bottom portion of the container body 1 flows downward from the drainage hole 75 provided in the lowest position portion 64d by utilizing the downward curved shape in which the central portion is the lowest position in the left-right direction. I try to let them. The arrows in FIGS. 6 and 7 indicate the flow of such drainage.

  Furthermore, each of the display substrate 71, the control substrate 72, and the power supply substrate 73 is located in the space 76 from which water entering the circumferential groove 64 is drained, but all cover cases 77, 78, which are isolated from the space 76. 79 is provided, so that even if the drainage is likely to occur, it is possible to prevent intrusion into the interior area of the electrical equipment. Further, since the cover case 77 of the display substrate 71 is located above the lower end of the drain hole 75 and connected to the drain hole 75 part, it is easy to prevent the drainage from getting wet. As shown in FIG. 8 together with the cover case 78, the control board 72 is located on the left side from the central portion in the left-right direction of the container body 1 where the drainage is guided, so that it is easy to prevent the drainage from reaching. Since the power supply board 73 is placed together with the cover case 79 and the electric pump 26 together with the drive motor, the power supply board 73 is placed far away from the front part of the exterior case 2 that flows down when drainage overflows from the pipe cover part 2d to the rear side. , Easy to prevent drainage.

  Further, a support structure that enables the operation of pressing the discharge operation member 61 into the opening 64b will be specifically described. The discharge operation member 61 is made of resin and is made of a tongue-like plate member as shown in FIG. 2, and an inwardly projecting shaft 61c is integrally formed with each of the attachment pieces 61b extending downward on the left and right sides of the back. . On the other hand, in FIG. 2, the bearing piece 81a in which the shaft 61c is fitted to the upper ends of the left and right side walls formed by having the separation portion by the slit 81c in the peripheral wall of the box-shaped main body portion 81b opened upward is integrally formed. A resin support member 81 as shown is combined to support the discharge operation member 61.

  More specifically, the support member 81 has a main body portion 81b having a rectangular shape in plan view. As shown in FIG. 1, the back range of the operation area 63 at the lowest position 64d of the circumferential groove 64 is separated from the arrangement portions of the drain holes 74 on both sides thereof. As shown in FIG. 1 and FIG. 6, it is fitted from above into a box part 64e having a rectangular shape in plan view that is isolated. At the time of fitting, a drain hole 81d protruding downward to the left and right of the bottom of the main body 81b is fitted into a drain hole 64f formed in the bottom of the box 64e. In this state, as shown in FIG. 6, a part of the cover case 77 of the display substrate 71 is applied to the mounting hole 64h, and a screw 83 is screwed from below into the mounting boss 81e rising from the bottom of the main body 81b. The part 81b and a part of the cover case 77 are fastened together so as to sandwich the box part 64e of the operation part 30 from above and below. Thus, even if the main body portion 81b of the support member 81 is a box type that opens upward and water may enter through the gap 65, the intruding water passes through the drain holes 64f and 81d and the drain holes described above. When it is tilted forward under substantially the same conditions as the drainage from 74, it is drained onto the stop valve 40 at the time of rollover. As shown in FIGS. 6 and 7, the cover case 77 is applied from below on the rear side corresponding to the box part 64e of the circumferential groove 64, and the box part 64e has a structure also serving as the bottom part thereof, and the main body part In addition to the drain hole 64f shown in FIG. 6 in which the drain hole 81d of 81b fits, the drain hole 91 shown in FIG. 7 in which the drain hole 74 of the circumferential groove 64 fits is also provided. However, the present invention is not limited to this, and the formation structure of the circumferential groove 64 to the operation unit 30 and the drainage structure to the inside of the operation unit 30 can be variously designed.

  On the other hand, the discharge operation member 61 is fitted with the shafts 61c on both sides of the rear part thereof in the bearing hole 81f of the bearing piece 81a of the support member 81 using the elasticity of the bearing piece 81a, and the circumferential groove 64 is formed. It can be mounted by fitting into the opening 64b from above. In this mounted state, the discharge operation member 61 becomes a lever-type operation member that can rotate about the shaft 61c. When the discharge operation member 61 is pressed, the free end side facing the front portion moves downward about the shaft 61c and is formed on the lower surface. The pushing protrusion 61d pushes the mediation portion 66 of the resin spring structure described above formed in the operation area 63 of the operation portion 30, and the discharge switch 62 is opposed to the mediation portion 66 to be pushed. Turn on the. As a result, the electric pump 26 is driven and the liquid content can be discharged. When the pressing operation of the discharge operation member 61 is released, the intermediary part 66 returns upwardly with the discharge operation member 61 by the resin spring structure, and the discharge switch 62 also automatically returns to the OFF state. Therefore, it is not necessary to operate a special urging means for returning the discharge operation member 61. The return position of the discharge operation member 61 can be described by the contact relationship with the rear edge of the opening 64b as shown in FIGS. 6 and 7, etc., and can be moved up carelessly or raised from the operation unit 30. There is nothing.

  Thus, if the discharge operation member 61 is a lever type, the operation resistance can be reduced by utilizing the lever ratio. For this purpose, as shown in FIGS. 6 and 7, it is preferable to set the rotation center position at the rearmost part of the discharge operation member 61 in order to maximize the lever ratio. However, the discharge operation member 61 may be of a non-lever type. For this, sliding projections (not shown) provided on the front and rear left and right sides are formed on the outer peripheral wall 64a or the inner peripheral wall 64g of the opening 64b. The discharge operation member 61 can be fitted and supported in the opening 64d while being elastically engaged with a sliding groove (not shown) from above.

  Finally, as shown in FIG. 1, the discharge operation member 61 is curved upward convexly in the left-right direction, tilted obliquely upward from the front part to the rear part, and loosely convexly convex in the operation part 30 In other words, because it is at the apex of the upwardly convex three-dimensional shape surface, it can be easily recognized and operated without any other obstacles. In addition, the position is the center position in the left-right direction, and is on the side of the body 1 of the overhanging portion 31, particularly on the side of the overhanging base from the body 1, and can be pressed by the operation portion 30 of the stationary body 1. It becomes the most stable position, and the body 1 can be given a sense of security with respect to the discharge operation without being finely moved. In addition, by this, the discharge operation member 61 is located at the highest front side in the front-rear direction of the lid 13 and at the central portion that is the uppermost part of the left and right, and thus is located at the apex of the three-dimensional surface convex on the lid 13. In addition, the operation unit 30 and the lid 13 are connected to each other while forming one accent with the front-rear direction cooperating on the upper surface of the vessel 1 adjacent to the unlocking member 23 having high operability. By being divided into secant lines, the selection operation according to the purpose can be achieved without confusion. At the same time, as shown in FIG. 1, the discharge operation member 61 is located far from both the outer opening 125b through which the vapor of the vapor passage 125 exits and the discharge port 25d, and is hardly affected by the vapor in the discharge operation. There is an advantage, and if it is too close to either the outer opening 125b or the discharge port 25d, there is an advantage that the influence of the condensed water of the steam becomes stronger and the drainage structure which is essential can be omitted.

  Further, as shown in FIGS. 1, 3, and 4, the liquid crystal display unit 55 is offset from the left side of the operation unit 30 that forms the three-dimensional plane with respect to the arrangement position of the discharge operation member 61. Since the liquid crystal display module 68 provided on the inner side is positioned away from the circumferential groove 64 to the side, it is easy to protect from the intrusion water collected in the circumferential groove 64 and drained. Moreover, the liquid crystal display module 68 is located higher than the lower end openings of the drain holes 81d, the drain holes 64f, and the drain holes 74 and 91 from the circumferential groove 64, and it is easy to prevent drainage from reaching. However, since the liquid crystal display module 68 is actually finished with a protective structure such as a resin mold, there is no practical problem if the flooding from above is prevented, and at least the liquid crystal display surface of the liquid crystal display module 68 is used. If the lower end openings of the drain holes 81d, the drain holes 64f, and the drain holes 74 and 91 are low, and more preferably the bottom portion 64c of the peripheral groove 64 is low, the liquid crystal display module 68 can be sufficiently waterproof.

  Further, the liquid crystal display module 68 is shown in FIG. 4 by the window frame 55a of the liquid crystal display unit 55 of the operation unit 30 shown in FIG. 1 and the liquid crystal display module holding unit 131 provided by being integrally formed with the cover case 77. As shown in the figure, since it is sandwiched from above and below, there is no backlash or misalignment caused by external force applied to the container 1 which is a discharge operation of the discharge operation member 61, so that the durability can be improved. Support for pinching also increases the heat release by increasing the open surface of the liquid crystal display module 68, and in combination with keeping away from the intrusion water collection path and drainage path, which may be hot water, High safety. Moreover, if the collection capacity | capacitance with respect to intrusion water is enlarged according to the depth and the width | variety of the surrounding groove 64, it has a margin for a large amount of intrusion at the time of discharging hot water, and intrusion hot water may reach directly. In addition to avoidance, it is possible to ensure thermal safety isolated from the low heat resistant display portion.

  In the example shown in FIGS. 10 and 11, the liquid crystal display unit 55 is disposed closer to the discharge operation member 61 on the side farther from the lowest portion 64 d of the circumferential groove 64, that is, on the front side of the operation unit 30. As a result, the liquid crystal display module 68 is further away from the collection position and drainage position of the circumferential groove 64, and more than the drain holes 81 d, drain holes 64 f and drain holes 74, 91 from the lower ends of the circumferential grooves 64. By ensuring that it is at a high position, it is easier to prevent intrusion and drainage. In addition, the low heat-resistant display portion such as the liquid crystal display module 68 is located on the side farthest from the drain hole 81d, the drain hole 64f, and the drain holes 74 and 91. Therefore, the drain hole 81d, the drain hole 64f, and the drain hole 74, 91, and the heat effect from the hot water drained downward can be greatly reduced. Since other structures are not particularly different from the previous example, detailed illustration and description are omitted. In addition, the same code | symbol is attached | subjected to the description object common to the previous example in a figure.

  Finally, the low heat-resistant display unit is the liquid crystal display unit 55, that is, the liquid crystal display module 68, and its center position is the left-right direction shown in FIG. 4 or the front-rear direction shown in FIG. The liquid crystal display module 68 has a relatively large display area and is conspicuous with the discharge operation member 61 in the operation unit 30, and both are in the left-right direction or front and rear of the discharge operation member 61 at the upper end of the container 1. While giving a unique accent lined up on the center line of the direction, it is possible to easily perform a discharge operation while confirming the display content on the liquid crystal display module 68 from such an arrangement.

  The present invention is practically used in an electric pot for home use and has a structure in which an independent discharge operation member can be attached and detached from above and can be maintained. The influence of the intrusion water from the water is eliminated, and the heat influence of the low heat resistance display portion when the intrusion water is hot water can be eliminated.
