[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container provided with a heater for heating a content liquid around an inner container housed in a container, and is used for household electric pots and the like. .

[0002]

2. Description of the Related Art An electric hot water storage container of this type is known in which a heater for boiling water and a heater for keeping heat are used in combination.

Both of these are assembled by combining both heaters as one heater, and are installed either at one location on the side peripheral surface of the bottom of the inner container or at one location on the lower surface of the bottom of the inner container. ing.

Therefore, even if there are a plurality of heaters, the labor for mounting can be simplified as in the case of one heater.

Further, since it has a heater for boiling water, by using this heater alone or together with the heater for keeping warm, it is possible to heat by a heater having a larger capacity than that at the time of keeping warm, and that much. The time required for boiling the content liquid can be shortened.

[0006]

In order to achieve the above-mentioned object, the present invention is applied to the lower surface and the side peripheral surface of the bottom portion of the inner container housed in the container to boil the content liquid. has a bottom surface heater and side heaters used kettle, energizing the bottom heater and side heaters alternately during chlorine removal mode for bleaching powder removed by continued boiling of liquid content control
It is characterized in that having a control means.

[0007]

In the above structure of the present invention, the control means alternates between the bottom heater and the side heater to use the bottom heater and the side heater for boiling the content liquid to remove the descaling by continuing the boiling of the content liquid. As a result, the convection generated in the content liquid when heated by the bottom heater and when heated by the side heater causes a difference corresponding to the difference in the heating position. By alternating convection, a low volume heating by one of the bottom heater and side heater keeps the boiling liquid enough to remove the liquid content after boiling to prevent strong bumping at the time of boiling water. However, since the content liquid is well disturbed as a whole, the bleaching of the chlorine due to continued boiling of the content liquid is active and uniform throughout the content liquid, and it is reasonably safe and heat-efficient in a short time. Also becomes useful in energy saving can be achieved bleaching powder removed.

To cope with this, it can be considered to increase the capacity of the heater. However, the conventional structure cannot deal with the problem.

To explain this, when the heater is applied to the lower surface and the side peripheral surface of the bottom of the inner container, other things are equipped to avoid this, and others installed in the body are avoided. Or, in order to avoid heat influence on a portion that needs to be thermally safe in use, the installation place of the heater tends to be relatively small.

Therefore, even if the capacity of the heater is further increased, if the installation area of the heater is limited, the proportion of the amount of heat that is not consumed for heating the content liquid in the inner container and is dissipated elsewhere increases the heater capacity. The thermal efficiency is extremely reduced, which is a disadvantage.

Therefore, heaters are provided separately on both the bottom surface and the side peripheral surface of the bottom of the container, and both heaters are operated for the boiling water mode and the descaling, so that the boiling state and the descaling state can be obtained at high speed. It is possible to do so.

[0012] However, such a problem may return and become a problem depending on the remaining amount of the content liquid.

For example, as the liquid level of the content liquid approaches the upper edge of the side heater, and falls below this, the heat escape to the upper part of the inner container of the side heater becomes large, and the heat loss becomes large.
Also. As a result, part of the temperature rises abnormally, causing a danger to the user and causing damage.

In view of the above, the present invention has an object to provide an electric hot water storage container in which such a situation is avoided in a heating mode in which a side heater is energized.

[0015]

In order to achieve the above-mentioned object, the present invention provides an electric hot water storage container provided with a heater for heating the content liquid around the outer circumference of an inner container housed in a container. In the heating mode in which the bottom surface of the bottom portion of the inner container, the bottom surface heater applied to the side peripheral surface, and the side surface heater are provided and the side surface heater is energized alone or together with the bottom surface heater, the content liquid is higher than the side surface heater. The main feature is that when the liquid level is below a predetermined level, only the bottom heater is switched to the energized state.

In the heating mode in which the side heater is energized, when the heating is switched to only the bottom heater, the content liquid replenishment warning can be given.

[0017]

In the above configuration of the present invention, when the side heater is in the heating mode in which the heater is energized alone or together with the bottom heater, if the content liquid is below a predetermined liquid level higher than the side heater, only the bottom heater is energized. As a result, while the liquid level of the content liquid approaches or falls below the upper edge of the side heater, the side heater continues to be energized and avoids a state similar to empty cooking. The set heating mode can be continued and achieved by heating only the bottom heater.

In the heating mode in which the side heater is energized, when switching to the energized state of only the bottom heater, if the content liquid is warned, the side heater is returned to the energized heating mode with the content liquid replenished. The desired heating can be achieved.

[0019]

01 is used. Pour-out operation key 102 provided on operation panel 201 provided on the upper surface of beak-shaped protrusion 12
Is provided so as to press the pressure sensor 103. The pressure sensor 103 converts the difference in the pressing force during the pouring operation into an electric signal and inputs the electric signal to the microcomputer 101, whereby the pouring pump 13 The drive voltage is switched to control the pouring flow rate.

At the free end of the body lid 62, a lock member 69 is provided which elastically engages the locking portion 71 of the shoulder member 14 by the bias of the spring 72 and locks the body lid 62 in the closed state. Has been.

The lock member 69 is guided forward and backward by a projection 83 formed on the upper surface of the back plate 82 of the body lid 62.

It is properly connected through the display circuit 305. The operation control will be described below. FIG. 4 shows a microcomputer 10.
2 is a flowchart of a main routine showing the main operation control of No. 1, in which the initial setting of step # 1 is first performed when the power is turned on, and then the processes according to various inputs and outputs are performed (step # 2). Next to the boiling process (step # 3) is called, when the content liquid is lower than the retained temperature, that is, when the temperature by adding pour water early or liquid content is low, also reboiled by reboiler-chlorine removal setting key 104 Is set, when the content liquid is in a high capacity state by all of the side heaters 61a and bottom heaters 61b, 61c,
Moreover, the heating is controlled from a wide area to a boiling point with good thermal efficiency.

When the operating portion 79 is pushed down in this state, the lock release lever 77 is rotated counterclockwise and the projection 78
The sloping surface 75 of the lock member 69 is pushed by the lock member 69 against the spring 68, and the lock member 69 is retracted to disengage from the locking portion 72. Therefore, the lock of the body lid 62 in the closed state is released. At the time when this lock release is completed, there is a play in the unlocking direction between the lock release lever 77 and the body lid 62, and the body lid 62 is released from the pressing operation of the lock release lever 77. It is slightly rotated in the opening direction by the spring 68 regardless of whether it is performed or not.

As a result, the lock member 69 is slightly displaced upward from the position of the locking portion 71, so that the lock member 69 is again moved to the locking portion 72 by the natural operation of releasing the lock and releasing the operating portion 79. The body lid 62 is automatically opened to the fully opened state by the spring 68 without any engagement.

Prevents easy unlocking.

On the lower surface of the back plate 82 of the vessel lid 62, the inner container 2
A metal inner lid 85 that closes the rear of the
It is screwed at 0. Outer periphery of inner lid 85 and back plate 82
A seal packing 86 facing the rim of the inner container 2 is sandwiched between and, and when the body lid 62 is closed, the inner lid 85 contacts the rim of the inner container 2 at the seal packing 86 portion. Close the inner container 2.

A steam passage 87 is provided between the inner lid 85 and the back plate 82 to allow steam generated in the inner container 2 to escape to the outside. The steam passage 87 has an opening 88 to the inner container 2 side in the inner lid 85, and an opening 89 to the outside on the upper surface of the rear side of the vessel lid 62. A valve chamber 91 fitted to the back plate 82 from below is provided in the opening 88, and a water stop valve 92 at the time of tipping is provided in the valve chamber 91 which is closed when the body 1 falls.

As described above, the bottom heater 61b and the side heater 61a for boiling the content liquid are used to continuously control the boiling of the content liquid to remove the descaling liquid, which is a control means.
Since the micro computer 101 alternately energizes the bottom heater 61b and the side heater 61a, the bottom heater 61b
There is a difference corresponding to the difference in the heating position in the convection that occurs in the content liquid between when heating by means of the side heater 61a and when heating by the side heater 61a, and this different convection occurs alternately in the content liquid during removal of scaly. With this, while keeping the boiling state to the extent that the content liquid after boiling can be removed by low-capacity heating by one of the bottom heater 61b and the side heater 61a, the strong content boiling such as when boiling water is prevented. As a result, the chyle emission due to the continued boiling of the content liquid is active and uniform throughout the content liquid, and it is reasonably safe and heat-efficient, and the descaling is achieved in a short time. It is also energy-saving and convenient.

As a result, the outflow of the content liquid to the outside is suppressed, and it is possible to provide a sufficient time margin for returning the container 1 to the normal state before the outflow to the outside. For this reason, the passage cross-sectional area of the outlet 94 from the reservoir 93 to the downstream side is made small, and the shape of the first reservoir 93 relative to the outlet 94 is defined by the front, rear, left and right directions of the container 1. Various measures are taken such as having a spread on the upper surface side of the body lid 62.

Control circuit 1 mounted on the circuit board 48
00 is the one using the microcomputer 101. The pouring operation key 102 provided on the operation panel 201 provided on the upper surface of the beak-shaped protrusion 12 is provided so as to press the pressure sensor 103, and the pressure sensor 103 measures the difference in pressing force during the pouring operation. By converting the signal into an electric signal and inputting it to the microcomputer 101, the drive voltage of the pouring pump 13 is switched to increase / decrease the pouring flow rate.

The operation panel 201 is as shown in FIG. 2. In addition to the pouring operation key 102, the reboiling / scaling removal setting key 104, the timer setting key 105, the pouring lock /
A release key 106, a liquid volume display unit 107, boiling, descaling, and heat retention display units 108 to 110, and timer set time display units 111 to 113 are provided.

The reboil / descaling removal setting key 104 and the pouring lock / release key 106 are designed so that the setting mode is changed to a rotary type each time they are operated.

FIG. 3 shows a control circuit 100. In the microcomputer 101, as shown in the figure, the electric and electronic parts related to the various inputs and outputs are an A / D converter 301, a sensor input circuit 302, a switch circuit 303, and a drive circuit. 304,
It is properly connected through the display circuit 305. The operation control will be described below. FIG. 4 is a flow chart of the main routine showing the main operation control. After the power is turned on, the initial setting of step # 1 is first performed, and then the processing according to various inputs and outputs is performed (step # 2).

Next, the boiling process (step # 3) is called, and when the content liquid is lower than the heat retention temperature, that is, when the temperature is low due to the initial supply of water or the addition of the content liquid, the re-boiling / scaling removal setting key 104. When reboil is set by, the content liquid is controlled to be heated at high speed from the wide area to the boiling in a high capacity state in a high capacity state by all of the side heaters 61a and bottom heaters 61b and 61c.

Subsequently, the heat retention process (step # 4) is called, and after the initial boiling or re-boiling, the bottom heater 61
b, 61c, a small-capacity bottom heater 61 for keeping heat
Only c is turned on and the content liquid is controlled to be kept at a predetermined temperature so that there is no heat loss due to excessive heating.

The bottom surface heaters 61b, 61c are applied to the bottom surface of the bottom of the inner container 2 to efficiently retain heat by heating in a small-capacity energized state. The heaters 61b and 61c do not come to the upper side, and in a heat-retaining state where they are easily placed for a long time, it is difficult to invite an empty cooking state, and it is easy to achieve safety in use.

In this sense, the side heater 61a should be provided as low as possible in order to prevent air-drying.

Further, the timer process (step # 5)
Is called and the timer is set by the timer setting key 105, delay control is performed so that the boiling operation start time is delayed to the time required to boil the content liquid at the timer setting time and then the boiling operation is started. To do.

Next, when the descaling process (step # 6) is called and the re-boiling / descaling removal setting key 104 is operated in the descaling mode, the boiling operation in step # 3 should be continued for a predetermined time. Control. However, the boiling operation may be repeated intermittently to remove the descaling. In addition, during the descaling process, the side heater 61a and the bottom heaters 61b and 61c are alternately energized. In this case, the content liquid is convected when heated by the side heater 61a and the bottom heaters 61b, 61.
Since the content liquid is disturbed by the difference between the convection current when heated in c and the heating position, the content liquid is disturbed, so that the odor and the diffusion of foreign substances such as scaly and its compounds can be promoted.

Next, the pump processing subroutine (step #
7) is called, the pouring flow rate is set according to the pressing force of the pressure sensor 103 by the pouring operation unit 102, and the motor 14 of the pouring pump 13 is driven to obtain this set pouring flow rate.

Finally, after the other processing (step # 8) is completed, the process returns to step # 2 and the above control is repeated thereafter.

The side heater 61 in each case by the above processing
FIG. 5 shows the energization states of the a and bottom heaters 61b and 61c and the temperature change of the content liquid.

Particularly in this embodiment, in the boiling mode and the descaling mode in which the side heater 61a is energized,
When the liquid level of the content liquid is below the semi-empty cooking prevention liquid level A which is set just above the upper edge of the side heater 61a as shown in FIG. 1, only the bottom heaters 61b and 61c are energized. To achieve the set heating mode.

As a result, the content liquid prevents the semi-empty cooking liquid level A.
Although it is below, the side heater 61a continues to be energized, heat loss such that a large amount of heat from the side heater 61a escapes to the upper part, and avoiding a state similar to idle cooking and damaging each part, are avoided, Moreover, the set heating purpose is achieved.

When only the bottom heaters 61b and 61c are energized, the total amount of heat generated in the energized state together with the side heater 61a can be satisfied. However, the bottom heater 61 is set as a semi-air cooking prevention mode set as a special case.
It is disadvantageous in economic design to temporarily increase the amount of heat generated by energizing only b and 61c.

Therefore, in the case of the present embodiment, the bottom heaters 61b and 61c are energized with a heat amount normally set.

Therefore, the time required for each operation of boiling, re-boiling, and descaling becomes slightly longer as shown by the broken line in FIG. Further, the alternate energization control of the side heater 61a and the bottom heater 61b in the case of removing the scale is omitted.

In addition, the boiling, re-boiling, and descaling operation by energizing only the bottom heaters 61b and 61c are in a state in which there is not enough liquid content, so the content liquid is urgently needed except when a small amount of boiling water is needed. Is preferably replenished so that normal heating is performed.

Therefore, in the present embodiment, when the side surface heater 61a is in the energized mode and the content liquid is the semi-empty cooking prevention liquid level A, only the bottom surface heaters 61b and 61c are energized. Warning display 3 to replenish the battery
11 (FIGS. 2 and 3) is lit and displayed.

[0067]

According to the present invention, by using the bottom heater and the side heater for boiling the content liquid to remove the descaling by continuing the boiling of the content liquid, the control means controls the bottom heater and the side heater. Since electricity is applied alternately, there is a difference in convection generated in the content liquid between when heating with the bottom heater and when heating with the side heater, which corresponds to the difference in the heating position. As different convections occur alternately, low volume heating by one of the bottom heater and side heaters keeps the boiling liquid enough to remove the content liquid after boiling, and prevents strong bumping, such as when boiling water. However, since the content liquid is well disturbed as a whole, the bleeding of the chlorine due to the continued boiling of the content liquid is actively and evenly distributed throughout the content liquid, and it is reasonably safe and heat-efficient in a short time. Also becomes useful in energy saving can be achieved bleaching powder removed.

Although the present embodiment does not have a heating mode in which the side heater 61a is independently energized, even in such a heating mode, the bottom heater 61b, when the content liquid reaches the semi-empty cooking prevention liquid level, It is also possible to switch to energization of only 61c.

FIG. 6 shows a second embodiment of the present invention. In this embodiment, since the side surface heater 61a is provided in addition to the bottom surface heaters 61b and 61c, the capacity of the bottom surface heaters 61b and 61c is set to be smaller than that when only this is provided, and the inner container 2 The distance S to the temperature sensor 33 can be increased by providing the bottom surface of the bottom surface small toward the outer circumference. A spring 28 for pressing the heater is integrally formed with the heat shield plate 24.

Since the temperature sensor 33 is located a little far from the bottom heaters 61b and 61c as described above, it can be prevented from being directly affected by the heat from the bottom heaters 61b and 61c. As described above, the temperature of the content liquid can be accurately detected without providing the heat shield wall 34.

Moreover, since the temperature sensor 33 is positioned so as to be higher than the actual empty cooking liquid level B by H, the bottom heaters 61b, 61 are set before reaching the empty cooking liquid level B.
The heat from c is strongly conducted through the bottom portion of the inner container 2 in which the liquid content has been lost, and the empty cooking state can be reliably detected immediately before that, thus improving the safety in use.

FIG. 7 shows a third embodiment of the present invention, in which the side heater 61a is lowered to bring the upper edge position closer to the empty cooking level B, so that the semi-empty cooking prevention level A is lowered accordingly. can do. Therefore, heating modes such as boiling, re-boiling, and descaling can be performed to a smaller liquid level by energizing both the side surface heater 61a and the bottom surface heaters 61b and 61c.

8 and 9 show a fourth embodiment of the present invention, in which a circular bottom portion 321 is formed on the inner container 2 having a rectangular cross section, and bottom heaters 61b and 61c are formed on the bottom surface of the bottom portion 321.
And a side heater 61a is wound around the side surface.

As a result, the side heater 61a is easily wound around the rectangular inner container 2. In addition, the side heater 61a
When the both end connecting portions 322 to be screw-connected when winding is opposed to the corner portion of the rectangular inner container 2 as shown in FIG. 9, the overhang of the both end connecting portions 322 to the outer circumference of the inner container 2 is eliminated, It is possible to prevent the other members and electronic devices from being easily disturbed.

Also, the spout 11 can be connected to the inner container 2 without using the corners of the inner container 2 as shown in FIG. 9 without interfering with the installation of the bottom heaters 61b and 61c.

In this embodiment, the limit liquid level for pouring through the pouring path 11 is set to the semi-empty cooking prevention liquid level A. Therefore, from the semi-empty cooking liquid level A to the empty cooking liquid level B, there is only a reduction due to the evaporation of the content liquid, so it is possible to prevent the semi-empty cooking prevention liquid level A from easily shifting to the empty cooking liquid level. ,
It can improve the safety of use.

FIG. 10 shows a fifth embodiment of the present invention. The tightening band 323 for tightening the side heater 61a from the outer surface and winding the side heater 61a around the bottom 321 is formed in an L-shaped cross section so that the side heater 61a does not easily come off. It was done like this.

[0078]

According to the present invention, in the heating mode in which the side heater is energized alone or in combination with the bottom heater, if the content liquid is below a predetermined liquid level higher than the side heater, only the bottom heater is energized. By doing so, while the liquid level of the content liquid approaches or is lower than the upper edge of the side heater, the side heater continues to be energized and avoids a state similar to empty cooking, and The set heating mode can be continued and achieved by heating only the bottom heater, and the purpose of use can be achieved while ensuring the safety of use when the remaining amount of the content liquid is small.

In the heating mode in which the side heaters are energized, when switching to the energization state of only the bottom heater, a warning is issued to replenish the content liquid. When the content liquid is replenished, return to the heating mode in which the side heaters are energized. By achieving the heating as set, it is possible to promote normal use by replenishing the content liquid while continuing safe use when the remaining amount of the content liquid is small.
