Description

Description: TECHNICAL FIELD The present invention relates to various liquid containers such as electric pots, and more particularly to a liquid container in which an electric pump is used to pour an internal solution out of a body through a pour passage. Is.

(Prior Art) In this type of liquid container, the spout for pouring the solution in the spout passage to the outside must be provided so as to project outside the container.

In addition, this amount of projection is provided so as to pour or guide the solution in the pour out to a position as far as possible from the container, so that a relatively large amount of projection is required.

On the other hand, if the amount of protrusion is large, it may be said that it will be bulky when not in use or stored and will be a hindrance to others.

In order to solve these conflicting problems, the conventional spouting part of the spout and the guide part that guides the poured inner solution to a predetermined position are projected to the retracted position inside the container and the outside of the container. It has been made possible to move in and out of the pouring position.

Japanese Patent Laid-Open No. 1-299521 shows an example of this. This has a vertical discharge body that guides the poured internal solution diagonally below the front of the container, and this discharge body is formed in a large concave part formed vertically from the upper center of the front part of the container. And the upper end is pivotally supported, and by arc rotation about this pivot, the ejector moves into and out of a storage position in which it is stored in the recess and a lower end is in a pouring position in which it largely overhangs the body. I am able to do it. Also, equipped with a push-type lock body in the recess,
As a result, every time the discharge body is pushed, the discharge body is automatically pushed out to the pouring position by releasing the lock position by the lock body and the storage position in the recess.

(Problems to be solved by the invention) However, in the above-mentioned conventional one, in order to provide the discharge body so as to be able to move in and out, a relatively large vertical recess is formed in the upper center of the front center of the body, Support for the discharge of the discharge body,
Since the guide is provided and the lock body is provided in the recess, the structure of the body becomes complicated, and the recess and the lock body project inward from the center of the front part of the body to the inside of the body. A dead space is created, which leads to an increase in the size of the body. Moreover, although the discharge body is automatically locked in the storage position by the lock body or automatically pushed out to the pouring position, it is still a manual operation, and it is still troublesome to use. .

Therefore, the present invention has an object to solve such a problem, and is a convenient liquid for use that can automatically move the spout pipe in and out with a simple and compact power transmission structure with a small number of parts. The purpose is to provide a container.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention forms an exterior of a container in a liquid container in which an electric pump is used to discharge an internal solution to the outside of the container. Between the outer case and the inner container housed in the outer case, the pouring pipe of the pouring path for pouring the internal solution from the lower part of the body to the upper part, and the lower part of this pouring pipe as the fulcrum Provided with a motor for rotating the spout pipe in an arc, and connecting the spout pipe of the spout passage forming the spout for pouring the internal solution outside the container to the spout pipe, and providing the spout pipe inside the container. It is characterized in that it is adapted to be withdrawn and retracted into a retracted position retracted into the body and an ejection position protruding from the body by the arc rotation of the spout pipe.

(Operation) According to the above configuration of the present invention, the internal solution is poured out of the vessel simply by giving a simple movement to the pouring pipe forming the pouring path to make an arc rotation with the lower portion of the pouring pipe as a fulcrum. The spout pipe that forms the spout to be ejected can be moved in and out, and in combination with this, a simple and compact power transmission mechanism with a small number of parts allows the spout pipe not only to protrude but also to retract. Automatic access to and from the storage location can be achieved. In addition, this withdrawal movement mechanism can be installed by using the normal extraction pipe storage space, which is provided with the extraction pipe between the inner container inside the container and the outer case, so that the arc of the extraction pipe can be rotated. It is not necessary to provide a special effective space for the above, and it is possible to avoid the inconvenience and the appearance that affect the size and the outer shape of the body.

(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 a resin injection pipe which is connected to the discharge port 45 of the electric pump 44 through a silicone rubber connecting pipe 46 and rises in the body 1. Exit pipe 14
7 and the water stop valve 47 at the time of fall connected to the upper end of this spout pipe 147.
And a water outlet valve 47 at the time of falling and a spout pipe 49 connected via an elbow 48 made of silicon rubber.

The electric pump 44 is driven by a motor 51 directly connected to the impeller, which is driven to rotate, so that the content liquid flowing into the pouring passage 31 up to the same level as in the inner container 4 is discharged from the pouring passage 31.
Send to 32 side. However, the spout 31 has a spout tube 49 that is projected and retracted from the body 1. Therefore, it is considered that the content liquid is discharged by the operation of the electric pump 44 on the condition that the spout pipe 49 projects from the container 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 side wall of one flat surface 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 tube 49 is performed by driving the geared motor 62 connected to the spout tube 147 via the arm 61. The arm 61 is directly connected to the motor 62 and has a forked portion 61a at the tip.
Is engaged with the spout pipe 147. When the motor 62 is started by this, the arm 61 is rotated forward or backward depending on the rotation direction of the motor 62 to swing the spout pipe 147. At this time, the spout pipe 147 is swung forward or backward using the bending of the joint pipe 46 connecting to the electric pump 44 as a hinge function. Due to this swing, the outlet pipe 147 is
The spout 49 connected to it is advanced to the front pouring position of the outer case 2 (phantom line in FIGS. 1 to 3) or retracted to the storage position where the front end surface 55 is flush with the outer case 2. Let 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. Sliding spout 49 and swinging spout 14
The change in angle with 7 is absorbed by the bending of the elbow 48.

The electric pump 44 and the motor 62 are arranged in the space 63 formed around the inner container 4 in the body 1 together with the discharge pipe 147 (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. .

As shown in FIGS. 1 and 3, the operation surface 5 has a spout pipe.
A liquid amount display portion 71 located at the left end adjacent to the front end surface 55 of 49,
The time display section arranged vertically on the right side of the liquid volume display section 50
72, descaling display unit 73, boiling display unit 74, heat retention display unit 7
5, the timer set operation unit 76, the descaling operation unit 77, the reboil operation unit 80, which are vertically arranged on the right phosphorus, and the pouring outlet operation unit 78 and the hot water operation, which are arranged on the right phosphorus. Each section 79 is provided.

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.
It is connected to the control circuit 82 (Fig. 6) mounted on the 81.

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
93 is held by a guide portion 94 in the outer case 2 so as to be able to move back and forth, 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 outlet pipe 147 of the outlet passage 31 serves as a liquid level detection sensor 124. The injection pipe 147 may be insulating, and may be made of glass, but resin has a higher dielectric constant, so it is easier to obtain a capacitance change, and the liquid surface level caused by swelling due to surface tension around the liquid surface. The non-specificity of can be suppressed. The liquid level detection sensor 124 has an aluminum foil 125 wound around the outer circumference of a spout pipe 147 to form a first electrode and is covered with an insulating sheet 122. The base pipe 41 is electrically connected to the liquid content in the spout pipe 147. Is the second electrode. The first electrode 125 and the content liquid in the base pipe 41 communicating with the second electrode 41 form a capacitance sensor 127 facing each other via an insulating peripheral wall which is a discharge pipe 147, and the size of the facing region. That is, it is possible to obtain the electrostatic capacity according to the liquid level height of the content liquid.

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, the heater 3 is divided into a warming heater 3a and a boiling water heater 3b as shown in FIG. 6, 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 process moves to 10 and 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. As a result, the spout pipe 49 is retracted from the spout position to the storage 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 spout tube 49 is slidably fitted onto the horizontally bent guide tube 141 at the upper end of the spout tube 147 so as to be withdrawn and withdrawn. A passive piece is provided at the base of the outlet pipe 49.
142 is integrally formed, and the passive hole 14 of this passive piece 142 is
One end of the intermediary lever 143 is fitted to 2a. The intermediate lever 143 is pivotally supported by a shaft 144 at an intermediate portion and the other end is a motor.
The bifurcated portion 61a of the arm 61 directly connected to 62 is engaged. As a result, when the motor 62 is rotated in the normal direction, the spout pipe 49 moves the arm 6
1. It is projected through the intermediary lever 143 to the pouring position shown by a virtual line in the figure. When the motor 62 is rotated in the reverse direction, 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.

In short, the present invention is a liquid container in which the electric pump 44 pours out the internal solution to the outside of the body 1 through the pouring path 31, and the outer case 2 and the inside of the outer case 2 which form the exterior of the body 1. A discharge pipe of a discharge passage 31 for discharging the inner solution from the lower part to the upper part of the container 1 between the inner container 4 and the inner container 4.
147 and a motor 62 for rotating the pouring pipe 147 in an arc with the lower part of the pouring pipe 147 as a fulcrum, and pouring the pouring path 31 forming a pouring port 32 for pouring the internal solution to the outside of the vessel 1. The outlet pipe 49 is connected to the spout pipe 147 and is provided inside the body 1, and the spout pipe 49 is retracted into the body 1 by the arc rotation of the spout pipe 147 and protrudes from the body 1. It is characterized in that it is adapted to be withdrawn and withdrawn to the pouring position.

As a result, the pouring port 147 that forms the pouring path 31 is simply given a simple movement in which the lower part of the pouring pipe 147 is rotated around the lower part of the pouring pipe 147 as a fulcrum, and the pouring port 32 that pours the internal solution out of the vessel 1 It is possible to move the spouting pipe 49 back and forth, and in combination with this, a simple and compact power transmission mechanism with a small number of parts allows not only the projecting spouting position of the spouting pipe 49 but also the retracted storage position. An automatic exit / entry can be achieved. Further, since this ejecting / retracting mechanism can be installed by using a normal pouring pipe storage space in which the pouring pipe 147 is provided between the inner container 4 in the body 1 and the exterior case 2, the pouring pipe 147 can be installed. It is not necessary to provide a special effective space for the arc rotation of the above, and it is possible to avoid inconvenience and appearance that affect the size and outer shape of the body 1.

(Effects of the Invention) According to the present invention, the internal solution is poured out of the container simply by giving a simple motion to the pouring pipe forming the pouring path to make an arc rotation with the lower portion of the pouring pipe as a fulcrum. The outlet pipe that forms the outlet can be moved in and out, and in combination with this, a simple and compact power transmission mechanism with a small number of parts allows not only the protruding position of the outlet pipe but also the retracted storage position. An automatic exit / entry can be achieved. In addition, this withdrawal movement mechanism can be installed by using the normal extraction pipe storage space, which is provided with the extraction pipe between the inner container inside the container and the outer case, so that the arc of the extraction pipe can be rotated. It is not necessary to provide a special effective space for the above, and it is possible to avoid inconvenience and appearance that affect the size and outer shape of the body.
