Description

Description: TECHNICAL FIELD The present invention relates to an electric pouring device for various liquid containers such as electric pots, and more specifically, a liquid container in which an internal solution is poured by an electric pump through a pouring path. The present invention relates to the electric pouring device.

(Prior Art) This type of electric pouring device is known, for example, from Japanese Utility Model Publication No. 62-130522 and Japanese Utility Model Publication No. 1-59529.

The one described in the above publication uses an electromagnetic air pump, and the one described in the above publication uses an electric liquid pump. In the case of using the electromagnetic air pump, pressurized air is sent into the body by the electromagnetic air pump to pressurize the content liquid. Then, the pressurized content liquid is guided to the outside of the body through a pouring path connected to the body and is poured out to the outside. Further, in the case of using a liquid pump, a liquid pump is provided below the pouring path for pouring the content liquid connected to the body. The liquid pump sends the content liquid flowing into the pouring path to the same level as in the body by the liquid pump to the pouring side of the pouring path, and pouring it out of the body through the pouring path.

In either case, the content liquid can be poured out only by turning on the switch for operating the pump, and the pouring can be stopped immediately by turning off the switch.

(Problems to be Solved by the Invention) By the way, an electric pot is put on a table, a sink, a stand or a shelf of an article storage, used, or handled in various ways. In any case, it will be used and handled in a small space. For this reason, if the body is bulky, it is not possible to effectively use the narrow space, and it is likely to cause interference with other people or get caught in a person, resulting in damage or a fall.

However, in the electric pot having the conventional electric pouring device, the pouring portion is largely projected to one side at the upper part of the body. Therefore, even if the shape of the body is made into a square shape that fits the corner portion, the above-mentioned problem cannot be solved because there is a bulkiness due to the protrusion of the spout.

As described in Japanese Patent Application Laid-Open No. 1-299521, the retracting structure of the spouting portion that alternately locks automatically to the storage position by the lock body and automatically pushes out from the storage position each time it is pushed. However, it is still inconvenient to use because it is necessary to manually inject and retract the spout, and this is a type of liquid container that pours the internal solution through the pouring path by an electric pump. Even if it is applied, there is a risk that the inner solution may be poured out by mistake even if it is in the storage position.

Therefore, it is an object of the present invention to provide an electric pouring device for a liquid container, which is convenient for use and which can prevent electric pouring while the pouring path is in the storage position to ensure safety in use. Is.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, the present invention includes an electric pump for pouring the content liquid through the pouring passage and a pouring outlet pipe for pouring out the pouring passage outside the body. With respect to the withdrawal operation mechanism for moving in and out to the pouring position and the storage position, a pouring operation button for operating the electric pump provided on the operation panel of the body and a withdrawal operation button for operating the withdrawal operation mechanism, When the spout operation button is operated and the spout pipe is in the retracted position, the spout pump is kept off to prevent the content liquid from pouring out, and if the spout pipe is in the spout position, it is turned on. It is characterized in that it is provided with a control means for controlling the operation of the electric pump at the moving-out position of the spouting pipe so that the content liquid is discharged.

(Operation) According to the above configuration of the present invention, the electric pump operates only by operating the pouring operation button provided on the operation panel, and the internal solution can be automatically poured through the pouring path. In addition, the withdrawal operation mechanism works only by the fingertip operation of the withdrawal operation button provided on the operation panel, and the ejection pipe of the ejection path automatically withdraws from the body, and the ejection pipe when not in use. Is the retracted storage position inside the container, and the spout pipe can be projected from the container during use, so that the spout pipe can be easily retracted and retracted. Moreover, even if the spout operation button is operated while the spout pipe is in the storage position, the control means operates to keep the electric pump in the off state. It is possible to avoid the inconvenience that the internal solution is poured out by being accidentally operated by a mischief such as an infant.

(Embodiment) A first embodiment of the present invention shown in FIGS. 1 to 10 will be described.

This embodiment shows a case where the present invention is applied to a boiling type electric pot. As shown in FIG. 3, the body 1 has a metal outer container 4 having a heater 3 housed in a resin outer case 2. The outer case 2 has a rectangular cross section as shown in FIGS. 1 and 2. The outer case 2 has a lateral strip-shaped operation surface 5 that is a slightly inclined upward slope on the selected one flat surface. The flat surface having the operation surface 5 is the front surface 6 of the body 1. The operation surface 5 is formed so as to slightly go around the flat surface on one side of the front surface 6.

The upper end of the outer case 2 has a high surface 7 which is slightly higher than the operation surface 5 on the left side of the front surface 6, and the other portion is a low surface 8 which is slightly higher than the operation surface 5. It is formed in a stepped shape. A rectangular opening 11 is formed in the lower surface 8. The opening 11 has an inwardly facing flange 12 at a slightly recessed position. On the other hand, the inner container 4 is also rectangular in cross section and has an outwardly facing flange 13 formed at its upper end. The inner container 4 is inserted into the opening 11 from above, and the flange 13 is received by the flange 12 of the outer case 2 via a packing 19.

A resin-made bottom plate 14 is fitted to the lower end of the outer case 2 from below. The bottom plate 14 has a large opening 15, and a metal lid plate 16 is applied to the opening 15.

The heater 3 is applied to the bottom surface of the bottom of the inner container 4 substantially concentrically with the bottom surface of the inner container 4, and a connecting metal fitting 17 is attached by welding or the like using the peripheral position of the bottom portion avoiding the attachment position of the heater 3. . This connecting fitting 17 is the lid plate
The inner container 4 is connected from the outside by the screw 16 and the screw 18, and the inner container 4 is attracted to the flange 12 of the outer case 2 by this connection and is stable inside the outer case 2.

A resin lid 21 is applied to the lower surface 8 at the upper end of the outer case 2. The lid 21 is formed in a shape flush with the outer surface of the outer case 2. A rear portion of the lid 21 is rotatably supported by a shaft 22 on a rim portion of the lower surface 8 so that the opening 11 can be opened and closed. On the lower surface of the lid 21, an inner lid 24 made of metal, which opens and closes the opening 23 of the inner container 4 simultaneously with the opening and closing, is integrally provided by a screw 27. The inner lid 24 has a seal packing 25 at a portion which closes the opening 23.
have.

The lid 21 is formed in a hollow shape, and has a steam removal passage 28 formed therein for allowing steam generated in the inner container 4 to escape to the outside through an opening 26 of the inner lid 24. As a result, even if the content liquid is heated to the boiling state by the heater 3, the vapor generated is not supplied to the passage 28.
Through to the outside of the body 1. Therefore, it is possible to avoid spontaneous increase in pressure in the space above the portion of the inner container 4 in which the content liquid is stored due to the vapor pressure.

A pouring path 31 is connected to the bottom of the inner container 4. The pouring outlet 32 at the tip of the pouring path 31 is exposed to the outside of the body 1 so that the electric liquid pump 44 provided in the middle of the pouring path 31 can pour the content liquid out of the body 1. ing. Therefore, the pouring path 31 serves as a path through which the inner container 4 communicates with the outside of the container 1. However, since the internal container 4 does not spontaneously pressurize as described above even when steam is generated, the content liquid is not accidentally pushed out through the pouring path 31 by the natural pressurization and is not poured out. .

As shown in FIG. 2 and FIG. 4, the spout passage 31 has a metal L-shaped base pipe 41 connected to the inner container 4 and an elbow 33 having a suction port 42 made of silicone rubber in the base pipe 41. The electric pump 44 which is connected to the electric pump 44 at the corner of the bottom of the body 1, and the resin pump which is connected to the discharge port 45 of the electric pump 44 through the silicone rubber connecting pipe 46 and rises in the body 1. Vertical tube 147
And the water shutoff valve 4 at the time of fall connected to the upper end of this vertical pipe 147.
7 and a silicone rubber elbow 48 on the water stop valve 47
And a spout pipe 49 connected via

The electric pump 44 is driven by a motor 51 directly connected thereto to rotate the impeller, and sends out the content liquid flowing into the pouring passage 31 to the pouring outlet 32 side of the pouring passage 31 to the same level as the inner container 4. . However, the spout 31 has a spout tube 49 that is projected and retracted from the body 1. Therefore, the pouring of the content liquid by the operation of the electric pump 44 is performed by the pouring pipe 49.
It is considered that it is performed on the condition that the projecting body extends from the body 1 to a pourable position.

The above-mentioned retracting structure of the spout pipe 49 will be described. The outlet pipe 49 is held in a slide case 50 as shown in FIGS. 1, 3, and 4. The slide case 50 is a guide rail formed on the inner surface of the body 1 which is continuous with the recess 52 of the portion corresponding to the high-level surface 7 and the recess 52 of the outer case 2.
The operation surface 5 of the outer case 2 is guided by 53, and appears and disappears at an opening 54 provided at a position continuing to the side on the side not wrapping around the flat surface on one side of the outer case 2. Further, the projecting and retracting is performed along the flat side wall on one side at the corner portion of the exterior case 2 having a rectangular cross section.

The front end surface 55 of the slide case 50 has a shape flush with the outer surface of the outer case 2 in the retracted position. Front end face
55 is colored with the operation surface 5 in a color different from that of the outer case 2, and is formed in a shape and size so as to follow the operation surface 5 with the same width as that of the outer case 2 and wrap around the flat surface on the other side of the outer case 2. Has been done. As a result, the operation surface 5 and the front end surface 55 form a strip-shaped accent on the outer surface of the outer case 2 in a state of being flush with the outer surface of the outer case 2 and slightly wrapping around the flat surfaces on both sides.

The withdrawal operation of the spout pipe 49 is performed by the vertical pipe 147 and the arm 61.
It is performed by driving a geared motor 62 connected via. The arm 61 is directly connected to the motor 62 and has a forked portion 61a at the tip.
Is engaged with the longitudinal tube 147. This allows the motor 62
When is activated, the arm 61 is rotated forward or backward depending on the rotation direction of the motor 62 to swing the vertically oriented tube 147. At this time, the vertical pipe 147 uses the bending of the joint pipe 46 connecting to the electric pump 44 as a hinge function to move forward,
Alternatively, it is swung backward. This rocking causes the vertical pipe
147 stores the spout pipe 49 connected to it to the front spout position (phantom line in FIGS. 1 to 3) of the outer case 2 or the front end face 55 is flush with the outer case 2. Retract to position. The forward / backward movement of the spout 49 is guided by the slide case 50, and the spout 49 itself is stably moved forward / backward. The angle change between the sliding spout 49 and the swinging vertical pipe 147 is absorbed by the bending of the elbow 48.

The electric pump 44 and the motor 62 are arranged together with the vertical pipe 147 in a space 63 formed around the inner container 4 in the body 1 (FIGS. 2 and 4). Is mounted on a mounting board 64 vertically arranged in the space 63 (FIGS. 3 and 4). The mounting substrate 64 is inserted from below into a pair of opposed recessed grooves 65 formed on the inner surface of the outer case 2 as shown in FIG. 3, and finally the lower end is fixed to the outer case 2 with screws 66. .

On the operation surface 5 as the operation panel of the present invention, as shown in FIGS. 1 and 3, the liquid amount display portion 71 located at the left end adjacent to the front end face 55 of the spout pipe 49, and this liquid amount display The time display section 72, the descaling display section 73 arranged vertically on the right side of the section 50,
Boiling display section 74, heat retention display section 75, timer set operation section 76 arranged vertically next to them, descaling operation section
77, a re-boiling operation section 80, a spout exit / withdrawal operation section 78 as the exit / withdrawal operation button of the present invention, and a hot water operation section 79 as the pouring operation button of the present invention, which are arranged on the right of these Has been.

These are the control board mounted by screws 84 on the mounting board 64 shown in FIG. 3 together with the motors 51 and 62.
A control circuit 82, which is the control means of the present invention equipped in 81.
(Fig. 6).

The lid 21 is a spring provided on the pivot as shown in FIGS. 3 and 5.
It is always urged to open at 91. On the other hand, inside the high-level surface 7 of the outer case 2, as shown in FIG. 4, a lock member that engages with the recess 92 on one side of the front portion of the lid 21 and locks the lid 21 in the closed state. 93 is provided. Lock member
The guide 93 in the exterior case 2 automatically holds 93 so that it can move forward and backward, and can be retracted from a step surface 95 between the high-level surface 7 and the low-level surface 8. The lock member 93 is urged by a spring 96 so that it is always in the advanced position. As a result, when the lid 21 is closed, the lock member 93 is pushed back by the lid 21 along the upward slope of the tip thereof and once retracted against the spring 96, and when the lid 21 is completely closed, the lock member 93 faces the concave portion 92 thereof. The recess 92 is automatically engaged by the bias of the spring 96. Therefore, when the lid 21 is closed, the lid 21 is automatically locked in the closed state.

This locking of the lid 21 is performed by an unlocking member 97 provided on the high surface 7. The unlocking member 97 is the outer case 2
It is provided at a position facing the lock member 93 on the higher surface 7 so as to be vertically movable. The unlocking member 97 has a downwardly facing protrusion 98, which is in contact with the upward slope 99 of the locking member 93. As a result, in the state in which the lock member 93 locks the lid 21, the slope 99 pushes the protrusion 98 upward, and the unlocking member 97 is returned to the upward movement position. Therefore, when the unlocking member 97 is moved downward in this state, the protrusion 98
Pushes the slope 99 downward, the lock member 93
Be retreated against. When the locking member 93 is retracted, the lid 21
Since the engagement with the recess 92 is released, the lid 21 is unlocked. Therefore, the lid 21 is automatically opened by the bias of the spring 91.

The lid 21 can be attached to and detached from the body 1. This will be described.

As shown in FIGS. 3 and 5, the bearing 101 of the shaft 22 that pivotally supports the lid 21 is detachably attached to the rear portion of the outer case 2.
The lid 21 can be easily attached and detached from the body 1 by attaching and detaching. As a result, the inside of the container 1 can be easily washed and the lid 21 can be washed completely.

As shown in FIGS. 3 and 5, the bearing 101 is a bearing housing 10 provided at a rear portion of a shoulder portion forming an upper edge portion of the body 1.
2 has a mounting portion 103 that can be inserted and removed from above. The bearing housing 102 has a holder 104 that receives and holds the mounting portion 103, and under the holder 104, a pair of left and right locking members 106 are held so as to be separable from each other. Each locking member 106
Are biased away from each other by springs 107 so that their respective outward locking hooks 108 are always in end position within holder 104 (FIG. 5).

On the other hand, the mounting portion 103 of the bearing 101 is formed with an engagement hole 109 that engages with the locking hook 108. This allows bearing 101
When the mounting portion 103 of the above is inserted into the holder 104 of the bearing housing 102 from above, the mounting portion 103 first pushes the locking hook 108 inward against the spring 107, and then moves inward. 109 is opposed to the locking hook 108. At this time, the locking hook 108 is fitted into and engaged with the engagement hole 109 by the bias of the spring 107 to prevent the mounting portion 103 from coming off, so that the bearing 101 is fixed to the bearing housing 102 and the lid 21 is in the mounted state. be able to.

Each locking member 106 has an operating portion 111 protruding below the bearing housing 102, and the operating portions 111 are spring-loaded by fingers.
When operated so as to be close to 107, each locking hook 1
08 moves inward and disengages from the engagement hole 109 of the mounting portion 103, and the bearing 101 is unlocked. In this state, the bearing 101 can be removed from the bearing housing 102, and the lid 21 can be removed.

The control circuit 82 includes a microcomputer (hereinafter referred to as a microcomputer) 121. The heater 3 is configured to be able to keep the temperature by heating the content liquid at a suitable time and in a boiling state or at a suitable temperature by controlling energization between the boiling state and the heat retaining state through the heater driving circuit 123 by the control circuit 82.

The vertical pipe 147 of the pouring path 31 serves as a liquid level detection sensor 124. The vertical tube 147 may be made of insulating material, and glass may be used, but resin has a better dielectric constant, so it is easier to obtain capacitance changes, and the liquid surface level caused by swelling due to surface tension around the liquid surface. The non-specificity of can be suppressed. Aluminum foil 125 on the outer circumference of the vertical pipe 147 with the liquid level detection sensor 124
Is wound to form the first electrode and is covered with the insulating sheet 122, and the base tube 41 electrically connected to the content liquid in the vertically oriented tube 147 is used as the second electrode. The first electrode 125 and the content liquid in the base pipe 41 communicating with the second electrode 41 are vertically oriented pipes.
The electrostatic capacity sensor 127 is provided so as to face the insulating peripheral wall 147, and the capacitance according to the size of the facing area, that is, the height of the liquid level of the content liquid can be obtained.

The difference in capacitance depending on the liquid level is that the sensor 127
As shown in the figure, the A / D converter 12
By connecting via 8, input is made to the microcomputer 121. As a result, the microcomputer 121 determines the liquid level of the content liquid based on the input corresponding to the difference in capacitance. This determination result is displayed by turning on the number of LEDs 131 to 137 of the liquid volume display unit 71 connected to the microcomputer 121 via the display circuit 129, according to the liquid volume. The LED 131 at the bottom is to turn on the water when the liquid level has dropped to the extent that water needs to be supplied for use, and to make the water supply more noticeable than other colors and brightness. At this time, the buzzer 143 is sounded.

For the determination of the liquid level, it is easy to make a table of the relationship between the capacitance and the liquid level at a necessary stage, and make the determination based on this table.

On the other hand, as shown in FIG. 6, the heater 3 is divided into a heat retaining heater 3a and a boiling water heater 3b, which are connected to a heater drive circuit 141 and controlled by relays RY1 and RY2 of a control circuit 82. For this reason, the contacts R-1 and R of the relays RY1 and RY2
-2 is connected to the heaters 3a and 3b as shown in the figure. relay
RY1 and RY2 are turned on and off by transistors TR1 and TR2 which are turned on and off by a signal from the microcomputer 121. When the relay RY1 is turned on, the relay contact R-1 is turned on to turn on the heat insulation heater 3a, and when the relay RY2 is turned on, the relay contact R is turned on.
-2 is turned on and the water is heated to turn on the heater 3b. And by heating both the heaters 3a, 3b simultaneously energized, it is possible to boil the content liquid until boiling.By controlling the energization of only the heat-retaining heater 3a, the content liquid is heated to maintain a predetermined temperature before boiling. You can keep it warm.

Energization in the boiling water state is detected by the temperature sensor 142 (Fig. 3) When the liquid temperature is lower than the heat retention temperature and the water is required to be boiled, and when the reboil operation unit 80 is turned on in the heat retention state. When the temperature sensor 142 detects the boiling temperature, the temperature is returned to the heat retention state.

The energization in the heat retention state energizes the heat retention heater 3a while the temperature sensor 142 detects a temperature equal to or lower than a predetermined heat retention temperature, and stops energization of the heat retention heater 3a when the predetermined heat retention temperature is detected. For these controls, the temperature sensor 142 is also connected to the microcomputer 121 via the A / D conversion circuit 128.

Further, under the control of the microcomputer 121, each time the reboil operation unit 80 is turned on on the operation surface 5, the heat retention display unit 75 and the reboil display unit 74 are sequentially turned on individually, and the display unit continues to be turned on for a predetermined time or longer. The mode corresponding to is set and executed. However, when the reboil operation unit 80 is operated again, the operation mode setting can be changed in the same manner as described above.

Further, each of the timer set operation unit 76, the descaling operation unit 77, the outlet / retract operation unit 78, the hot water operation unit 79, and the reboiling operation unit 80 are connected to the microcomputer 121 via the switch operation unit 129. Each time the timer setting operation unit 76 is turned on on the operation surface 5, the display of the timer display unit 72 is sequentially turned on in a rotary manner, and the time corresponding to the finally turned on LED is set by the timer. This timer setting time is, for example, to automatically start the boiling operation while the user is out or sleeping, so that the content liquid that has just boiled after the set time is obtained. .

In order to achieve this, the microcomputer 121 utilizes the liquid amount information from the sensor 127, or information such as room temperature, or temperature rise characteristics or temperature decrease characteristics when the content liquid is heated or stopped heating, If you want to finish boiling the liquid in the set time, calculate how long before you need to start heating. A table created in advance may be used for this calculation.

The heating control of the content liquid will be specifically described below with reference to the flowchart of the heating control subroutine shown in FIG.

First, it is judged whether or not the descaling operation is selected by the descaling operation unit 77 (step # 1). If not, if the content liquid is less than 80 ° C., or if boiling is selected by the re-boiling operation unit 80 (step # 1). Only in # 2 and # 3), the process proceeds to step # 5, and the boiling operation is performed. Step # 1
When the descaling is selected in, the descaling F is set to "1" (step # 4), and then the boiling operation in step # 5 is performed.

When it is determined in step # 6 that boiling has ended, the process proceeds to step # 7, and it is determined whether the descaling F is "1". When the boiling operation is started from step # 2 or # 3, since the descaling F is not "1", the process moves to step # 8, and after the boiling end operation and the boiling notification by the buzzer 143 are performed, the operation is switched to the heat retention operation. . Here, the boiling operation from step # 2 corresponds to the initial boiling due to water supply or water replenishment, while the boiling operation from step # 3 corresponds to the re-boiling from the heat retention operation after boiling. The temperature change of the content liquid in these cases is shown in FIG. 8 (a).

If the descaling F is "1" in step # 7, step #
The temperature shifts to 10, the water is boiled, the heater 3b is turned off, and the internal timer is started. When the timer counts 3 minutes, the timer is reset (steps # 11 and # 12), and in step # 13, the water is heated and the heater 3b is turned on again and the timer is started. When the timer counts 1 minute, the timer is reset (steps # 14, # 15), and the heater 3b is turned off and the timer is started in step # 16. When the timer counts 3 minutes, the timer is reset (steps # 17, # 18), and in step # 19, the heater 3b is turned on to start the timer. When the timer counts 1 minute, the timer is reset (steps # 20, # 21). Therefore, as shown in FIG. 8, after the initial boiling is performed, the water is boiled every 3 minutes and the heater 3b is turned on and reboiled once for 1 minute each. In addition, chlorine compounds and the like in the content liquid can be vigorously emitted, and since the content liquid is in a high temperature state for a predetermined time from initial boiling and reboiling each time, it is possible to accelerate the emission of exhaled substances. . The so-called chlorine removal effect is sufficiently exhibited, and since boiling is not continued, there is no problem of excessive temperature rise.

When the descaling operation as described above is completed, the descaling F is reset to "0" in step # 22 and the process returns to step # 8. The temperature change of the content liquid in the descaling operation mode is as shown in FIG. 8 (b). The boiling may be continued for a predetermined time to remove the chlorine. The motors 51 and 62 are also connected to the microcomputer 121 via a motor drive circuit 141, and a spout outlet / withdrawal operation unit 78,
The spout pipe is driven according to the operation with the tapping operation section 79.
It is controlled so that it goes out and leaves 49, and takes out hot water.

This will be described with reference to the flowcharts shown in FIGS. 9 and 10.

FIG. 9 shows a leaving / receipt operation processing subroutine. When the spout exit / withdrawal operation unit 78 is operated, it is determined whether the protrusion F is 0 or not. When it is 0, the spout tube 49 is in a state where it is not projected to the spout position. At this time, set the protrusion F to 1,
The timer 62 is started and the motor 62 is turned on in the forward direction. As a result, the spout pipe 49 is moved from the retracted position to the spout position. When the timer A ends, the spout pipe 49 has reached the pouring position, and the motor 62 waits until the timer A ends.
Turn off. Then, the pouring position F is set and the process returns (steps # 31 to # 38).

When the spout F is not 0 when the spout outlet / retractor 78 is operated next time, the spout pipe 49 is in the spout position, and therefore, the spout F timer is moved back to the retracted position. Start B and turn on the motor 62 in reverse. This causes the spout pipe 49 to retract from the spout position to the retracted position. When the timer B ends, the spout pipe 49 has reached the storage position, the motor 62 is turned off, and the spout pipe 49 is stopped at the storage position. Next, the protrusion F and the pouring position F are reset to 0 and the process returns (steps # 31, # 32, # 41 to # 46).

FIG. 10 shows a hot water operation processing subroutine. When the hot water operation unit 79 is operated, it is determined whether the pouring position F is 1. This is to determine whether or not the spout pipe 49 is at the pouring position. The control is advanced so that hot water can be discharged only at the pouring position, and the motor 51 is turned on (steps # 51 to #).
53). At the same time, the time counter is started, and this counting is continued while the hot water operation section 79 is continuously operated. For this continuation, the motor 51 is set to the medium speed until it reaches 4 seconds so that the motor 51 is rotated at the medium speed. When the continuation is longer than 4 seconds, the motor 51 is set to high speed so that the motor 51 is rotated at high speed. When the operation of the hot water operation unit 79 is completed, the motor 51 is turned off and the process returns (steps # 54 to # 59).

As a result, hot water is discharged only while the spout pipe 49 is at the pouring position while the hot water operation portion 79 is being operated, and safety in use is ensured. When the hot water discharge operation continues for 4 seconds or more, the amount of hot water discharged per unit time can be increased, and the time required when a large amount of hot water is discharged can be shortened.

FIG. 11 shows a second embodiment of the present invention. In this embodiment, the outlet pipe 49 is slidably fitted onto the guide pipe 141 that is horizontally bent at the upper end of the vertically oriented pipe 147,
I am allowed to leave. A passive piece 142 is integrally formed at the base of the spout tube 49.
One end of the intermediary lever 143 is fitted to 142a. The intermediate lever 143 is pivotally supported by a shaft 144 at an intermediate portion, and the other end is engaged with a forked portion 61a of an arm 61 directly connected to the motor 62. As a result, when the motor 62 is normally rotated, the spout pipe 49 is
61, via the intermediary lever 143, it is projected to the pouring position shown by a virtual line in the figure. When the motor 62 is reversed, the spout pipe 49
Is retracted to the storage position shown by the solid line in the figure.

The present invention is not limited to the above embodiments and can be implemented in various modes. For example, the withdrawal of the spout pipe can be absorbed by a flexible expansion / contraction portion or the like in the middle of the spout passage, and various specific mechanisms for the withdrawal operation and the withdrawal drive can be designed.

Further, the electric pouring mechanism for electric pouring of the content liquid can be variously modified, such as adopting a pressurizing type pouring.

In short, according to the present invention, the electric pump 44 for pouring the content liquid through the pouring path 31 and the spout pipe 49 for pouring out of the body 1 of the pouring path 31 are discharged to the pouring position and the storing position with respect to the body 1. The exit / retract operation mechanism for retracting and the tapping operation button 79 for operating the electric pump 44 provided on the operation cotton 5 as the operation panel of the body 1 and the exit / retract operation for operating the exit / retraction mechanism. When the outlet / retractor operating section 78 as an operation button and the outlet port 49 are in the retracted position when the hot water outlet section 79 is operated, the electric pump 44 is kept in the off state to prevent the content liquid from being dispensed and the outlet If the pipe 49 is at the pouring position, the microcomputer 121 is provided as a control means for controlling the operation of the electric pump 44 at the moving-out position of the spout pipe 49 so that the liquid is discharged by turning it on. It is characterized by that.

As a result, the electric pump 44 operates only by operating the tapping operation section 79 provided on the operating cotton 5, and the internal solution can be automatically poured out through the pouring path 31. In addition, the withdrawal operation mechanism operates only by the hand operation of the withdrawal operation section 78 provided on the operation cotton 5, and the ejection port 49 of the ejection path 31 automatically withdraws from the body 1 and is not used. At this time, the spout pipe 49 can be set to the retracted position inside the body 1, and the spout pipe 49 can be projected from the body 1 at the time of use, so that the spout pipe 49 can be easily moved back and forth. You can Moreover, even if the hot water outlet operating portion 79 is operated when the spout pipe 49 is in the storage position, the microcomputer 121 as a control means operates to keep the electric pump 44 in the off state, so that the spout pipe 49 is in the storage position. However, it is possible to avoid the inconvenience that the electric pump 44 is erroneously operated by a mischief such as an infant and the internal solution is poured out.

(Effect of the Invention) According to the present invention, the electric pump can be operated only by operating the pouring operation button provided on the operation panel, and the internal solution can be automatically poured out through the pouring path. In addition, the exit and exit operation mechanism works only by the fingertip operation of the exit and exit operation button provided on the operation panel,
The spout pipe of the spout path automatically moves back and forth with respect to the body,
When not in use, set the spout tube to the retracted position inside the body,
When using it, the spout pipe can be projected from the body,
The withdrawal operation of the spout tube can be easily performed. Moreover, even if the spout operation button is created when the spout pipe is in the retracted position, the control means works to keep the electric pump in the off state. It is possible to avoid the inconvenience that the internal solution is poured out by mistake or by being acted by mischief such as an infant.
