Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric dispensing device for various liquid containers such as electric kettles.

(Prior art) This type of electric dispensing device is known, for example, from Utility Model Application No. 6213052
This method is known from Publication No. 2 (■), Japanese Utility Model Publication No. 1-59529 (■), etc.

The one described in the publication (2) uses an electromagnetic air pump, and the one described in the publication (2) uses a liquid pump. When using an electromagnetic air pump, the electromagnetic air pump sends pressurized air into the container to pressurize the liquid inside. Then, this pressurized liquid content is led out of the container through a discharge path attached to the container and is poured out. In addition, in the case of using a liquid pump, the liquid pump is provided at the lower part of the outlet path connected to the container body for pouring out the contents. The liquid pump sends out the content liquid flowing into the outlet path at the same level as the inside of the container to the pouring side of the outlet path, and pours it out of the container through the outlet path.

In either case, the content liquid can be poured out simply by turning on the switch that operates the pump, and the pouring can be stopped immediately by turning it off.

(Problems to be Solved by the Invention) By the way, an electric kettle is placed on a dining table, a sink, a stand or a shelf of an article storage, and is used or handled in various ways. In all cases, they will be used and handled in confined spaces. For this reason, if the vessel is bulky, it will not be possible to make effective use of a narrow space, and it may cause interference with other objects or get caught in people, leading to damage or falling.

However, in the conventional electric kettle equipped with an electric dispensing device, the dispensing spout largely protrudes from the upper part of the pot. For this reason, even if the shape of the vessel is made into a rectangular shape that fits into the corner, the above-mentioned problem cannot be solved because of the bulk caused by the protrusion of the spout. Further, the above-mentioned overhanging shape hinders the simplification of the product in terms of operation and appearance.

If this problem were simply addressed by a manually operated ejecting/retracting structure of the spout, it would be necessary to manually retract and retract the spout, and an external operating section for this operation would be required. It becomes a hindrance.

Therefore, the present invention skillfully utilizes the fact that it has an electric dispensing device, and can satisfy operational and external simplification, and the dispensing operation of the content liquid is performed when the dispensing path is at the dispensing position. It is an object of the present invention to provide an electric dispensing device for a liquid container that can be used safely under certain conditions.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, the present invention includes a lead-out path for guiding the content liquid to the outside of the vessel, and an electric pump for pouring the content liquid to the outside through the lead-out path. In an electric dispensing device for a liquid container, a storage position in which the outlet path is retracted into the container body;
The device is provided so as to be able to move in and out of the dispensing position protruding from the outer surface of the container, and is provided with an electric mechanism for moving the outlet path in and out, and an operation means for operating the electric mechanism as appropriate, and for operating the operation means for operating the electric pump. The invention is characterized in that it is made effective on the condition that the outlet path is at the pouring position.

(Function) According to the above configuration of the present invention, the content liquid is automatically poured out through the outlet path by the action of the electric pump. The outlet path for dispensing can be kept from protruding to the outer surface of the vessel by setting it in a stored position where it is normally retracted into the vessel when dispensing is not performed. Further, the outlet passage can be automatically projected from the storing position to the dispensing position protruding outside the container body by an appropriate operation of the electric mechanism by the operating means, and therefore can be projected by a simple operation regardless of the state in which it does not protrude from the outer surface of the container body. It is possible to pour out the liquid content.

Further, the outlet channel can be reliably stored from the pouring position to the storage position automatically, regardless of the shape of the outlet channel, etc., by appropriate operation of the electric mechanism by the operating means.

Furthermore, even if the operating means for dispensing the liquid content is operated, the operation is not valid unless the outlet channel is in the dispensing position, and the liquid content is dispensed even though the outlet channel is not in the dispensing position. Things like this can be avoided.

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

This example shows a case where the present invention is applied to a boiling type electric kettle. As shown in FIG. 3, the container body 1 includes an inner container 4 made of metal and having a heater 3 housed in an outer case 2 made of resin. As shown in FIGS. 1 and 2, the outer case 2 has a rectangular cross section. The exterior case 2 has a horizontal strip-shaped operation surface 5 that is a slightly inclined upward slope on the upper part of the selected one side of the flat surface. The flat surface having the operation surface 5 serves as the front surface 6 of the vessel body 1. The operation surface 5 is formed so as to extend slightly around the flat surface on one side of the front surface 6.

The upper end of the exterior case 2 has a high surface 7 on the left side, which is slightly higher than the operation surface 5 when viewed from the front surface 6, and a lower surface 8, which is slightly higher than the operation surface 5, on the other part. It is formed in a stepped shape. A rectangular opening 11 is provided in the lower surface 8.
is formed. An inward flange 12 is provided at a slightly recessed position in this frontage 11. The one-way container 4 also has a rectangular cross section and has an outward flange 13 formed at its upper end. The inner container 4 is inserted into the opening 11 from above, and the flange 13 is fixed to the flange 12 of the outer case 2 via a backing 19.

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

Further, the heater 3 is applied to the lower surface of the bottom of the inner container 4 almost concentrically thereto, and the connecting fitting 17 is attached by welding or the like using the circumferential edge of the bottom, avoiding the position of the heater 3. There is. This connecting fitting 17 is connected to the lid Fi, 16 from the outside by a screw 18, and the inner container 4 is connected to the flange 12 of the outer case 2 through this connection.
It is stabilized inside the outer case 2 because it is attracted to it.

The lower surface 8 at the upper end of the exterior case 2 has a resin 121
is assigned. The lid 21 is formed to be flush with the outer surface of the outer case 2. The rear portion of the lid 21 is rotatably supported by a shaft 22 on the mouth edge of the lower surface 8, thereby allowing the opening 11 to be opened and closed. A metal inner cover 24 is integrally provided on the lower surface of the cover 21 with a screw 27, and opens and closes the opening 23 of the inner container 4 simultaneously with the above-mentioned opening and closing. The inner lid 24 has a seal backing 25 at a portion that closes the opening 23.

The lid 21 is formed hollow, and has a steam vent passage 28 formed therein through which steam generated within the inner container 4 escapes to the outside through an opening 26 of the inner lid 24. Thereby, even if the content liquid is heated to a boiling state by the heater 3, the generated steam is allowed to escape to the outside of the container body 1 through the passage 2g. Therefore, it is possible to avoid a situation in which the pressure in the space above the portion of the inner container 4 in which the liquid is contained is naturally increased due to vapor pressure.

A lead-out path 31 is connected to the bottom of the inner container 4 . The spout 32 at the tip of the outlet path 31 faces the outside of the container body 1, so that the liquid inside can be poured out of the container body 1 by the action of an electric liquid pump 44 provided in the middle of the outlet path 31. It has become. Therefore, the outlet path 31 becomes a passage through which the inner container 4 communicates with the outside of the container body 1. However, since the pressure inside the inner container 4 does not naturally increase as described above even with the generation of steam,
The content liquid will not be inadvertently pushed out and poured out through the outlet path 31 due to the natural pressure increase.

As shown in FIGS. 2 and 4, the outlet path 31 includes a metal L-shaped base pipe 41 connected to the inner container 4, and this base pipe 4.
1 has a suction port 42 connected to it via an elbow 33 made of silicone rubber, and an electric liquid pump 44 located at a corner of the inner bottom of the container 1, and a joint pipe made of silicone rubber to a discharge port 45 of this electric liquid pump 44. A vertical pipe 46 made of resin that is connected through a pipe 46 and rising up inside the vessel body 1, a water stop valve 47 connected to the upper end of this pipe 46, and a water stop valve 47 made of silicone rubber. It is combined with a spout pipe 49 connected through an elbow 48 made of aluminum.

A built-in impeller of the electric liquid pump 44 is rotationally driven by a motor 51 directly connected to the electric liquid pump 44, and the liquid flowing into the outlet passage 31 to the same level as the inside of the inner container 4 is transferred to the spout 32 side of the outlet passage 3I. send out. However, the outlet pipe 49 of the outlet passage 31 is adapted to be retracted from the container body 1. For this reason, consideration is given to dispensing the content liquid by operating the electric liquid pump 44 on the condition that the spout pipe 49 protrudes from the vessel body 1 to a position where it can be dispensed.

The above-described retractable structure of the spout pipe 49 will be explained. The spout pipe 49 is held within a slide case 50, as shown in FIGS. 1, 3, and 4. Slide case 5
0 is a recess 52 in a portion corresponding to the high surface 7 in the vessel body 1
and a guide rail 53 formed on the inner surface that is continuous with the recess 52 of the outer case 2, and the operating surface 5 of the outer case 2 is placed in a position where it continues to the side of the one side of the outer case 2 that is not wrapped around the flat surface. It appears and disappears through the provided opening 54. Further, this protrusion and retraction is performed at a corner portion of the exterior case 2 having a rectangular cross section along one flat surface side wall.

The front end surface 55 of the slide case 50 has a shape that is flush with the outer surface of the exterior case 2 in the retracted position. In addition, the front end surface 55 is colored in a different color from the outer case 2 together with the operation surface 5, continues on the operation surface 5 with the same width, and has a shape and size that wraps around the flat surface on the other side of the outer case 2. It is formed. As a result, the operation surface 5 and the front end surface 55 are located on the outer surface of the outer case 2.
It forms a band-shaped accent that is flush with it and slightly wraps around the flat surfaces on both sides.

The ejecting and retracting movement of the spout pipe 49 is performed by driving the gear motor 2 connected to the vertical pipe 46 via an arm 61. The arm 61 is directly connected to the motor 62, and has a bifurcated portion 61a at the tip engaged with the vertical tube 46. When the motor 62 is started by this, the arm 61
The vertical tube 46 is rotated forward or backward depending on the direction of rotation of the tube 2. At this time, the dark blue tube 46 is swung forward or backward using the bending of the joint tube 46 connecting it to the electric liquid pump 44 as a hinge function. This swing causes the vertical pipe 46a to advance the spout pipe 49 connected thereto to the forward spouting position of the exterior case 2 (phantom line in FIGS. 1 to 3), or to push the front end of the vertical pipe 46a into the exterior case 2. 55 is moved back to the storage position where they are flush with each other. The forward and backward movements of the spout pipe 49 are guided by the slide case 50, and the spout pipe 49 itself is moved forward and backward in a stable manner. Sliding spout 49 and swinging vertical tube 4
6 is absorbed by the deflection of the elbow 48.

An electric liquid pump 44 and a motor 62 are connected to the vertical tube 4.
The electric liquid pump 44 and the motor 62 are arranged in a space 63 formed around the inner container 4 in the container body 1 (FIGS. 2 and 4), and the electric liquid pump 44 and the motor 62 are arranged vertically in the space 63. The attached mounting is attached to the board 64 (Figs. 3 and 4).
figure). For installation, the board 64 is inserted from below into a pair of opposing grooves 65 formed on the inner surface of the outer case 2 as shown in FIG.
It is stopped by.

As shown in FIGS. 1 and 3, the operation surface 5 includes a liquid volume display section 71 located at the left end adjacent to the front end surface 55 of the spout pipe 49, and a liquid volume display section 71 located at the left end adjacent to the front end surface 55 of the spout pipe 49; A time display section 72, a descaling display section 73, and a boiling display section 74 arranged in
, a heat retention display section 75, a timer set operation section 76, a descaling operation section 77, a reboiling operation section 80, which are arranged vertically to the right of these, and a pouring outlet/withdrawal operation section arranged to the right of these. 78 and a hot water tapping operation section 79 are provided, respectively.

These components, along with the motors 51 and 62, are mounted as shown in FIG. 3 to a control circuit 82 (FIG. 6) installed on a control board 81 mounted on a board 64 with screws 84.
It is connected to the.

! As shown in FIGS. 3 and 5, 21 is always urged in the open direction by a spring 91 provided on the pivot portion. On the other hand, on the inside of the high surface 7 of the exterior case 2, as shown in FIG.
A locking member 93 is provided for locking in the closed state. The locking member 93 is held movably back and forth by a guide portion 94 in the exterior case 2, and is capable of coming out and retracting from a stepped surface 95 between the high surface 7 and the low surface 8. The locking member 93 is always urged by a spring 96 to be in the extended position. As a result, when the lid 21 is closed, the locking member 93 is pushed by the upward slope of its tip by M21 and is once retreated against the spring 96, and when the lid 21 is completely closed, it faces the recess 92 of the locking member 93. The recess 92 is automatically engaged by the biasing of the spring 96. Therefore, the lid 21
When the lid 21 is closed, the lid 21 is automatically locked in the closed state.

This locking of the lid 21 is effected by a release member 97 provided on the upper surface 7. The unlocking member 97 is provided at a position facing the locking member 93 on the high surface 7 of the exterior case 2 so as to be movable up and down. The unlocking member 97 has a downward protrusion 98 that abuts an upward slope 99 of the locking member 93. As a result, when the locking member 93 is locking the lid 21, the slope 99 is pushing 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, so that the locking member 93 is retreated against the spring 96. When the lock member 93 is retracted, the recess 92 of 121
Since the lock is released, M21 is unlocked. Therefore, the lid 21 is automatically opened by the bias of the spring 91.

The lid 21 is removably attached to the vessel body 1. This will be explained.

As shown in FIGS. 3 and 5, a shaft 22 that supports M21
The bearing 101 is removably attached to the rear part of the outer case 2,
By attaching and detaching the bearing 101, the lid 21 can be easily attached and detached from the container l.

Thereby, the inside of the container body 1 can be easily cleaned, and the lid 21 can be washed completely.

As shown in FIGS. 3 and 5, the bearing 101 has a mounting portion 103 that can be inserted into and removed from a bearing housing 102 provided at the rear of the shoulder member 4 from above. The bearing housing 102 has a holder 104 that receives and holds the mounting portion 103, and a pair of left and right locking members 106 are held under the holder 104 so as to be removable. Each locking member 106 is biased away from each other by a spring 107, and each outward locking hook 108 is attached to the holder 1.
04 (see Figure).

On the other hand, the locking hook 10 is attached to the mounting portion 103 of the bearing 101.
An engagement hole 109 that engages with B is formed. This allows the mounting portion 103 of the bearing 101 to be attached to the bearing housing 102.
When inserted into the holder 104 from above, the mounting part 1
03 first enters while pushing the locking hook 10B inwardly against the spring 107, and when the locking hook 10B enters to the maximum limit, the engaging hole 109 faces the locking hook 108. At this time, the locking hook 108 is biased by the spring 107 into the engagement hole 1.
09 and prevents the attachment portion 103 from being removed, the bearing 101 is fixed to the bearing housing 102 and the lid 21 can be placed in the attached state.

Each locking member 106 has an operating portion 111 that projects below the bearing housing 102, and when the operating portions III are operated with fingers to bring them close together against the spring 107, each locking hook 108 is moved inward. It moves 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 microcomputer) 121. The heater 3 is energized by this control circuit 82 via a heater drive circuit 123 to be in a boiling state and a keeping-warm state, so that the liquid content can be heated to a boiling state or an appropriate temperature in a timely manner and kept warm.

The vertical pipe 46 portion of the outlet path 31 serves as a liquid level detection sensor 124 . The vertical tube 46 may be made of insulating material, and may be made of glass, but resin has a better dielectric constant, so it is easier to obtain changes in capacitance, and the liquid level level caused by swelling due to surface tension around the liquid surface. The unspecificity of can be suppressed.

The liquid level detection sensor 124 is constructed by wrapping an aluminum foil 125 around the outer periphery of the vertical tube 46 to serve as a first electrode and covering it with an insulating sheet 122, and connects the base tube 41 electrically to the liquid inside the vertical tube 46. is used as the second electrode. The first electrode 125 and the liquid inside the base tube 41 communicating with the second electrode 41 form a capacitance sensor 127 that faces each other via an insulating peripheral wall, which is a vertical tube 46, and the size of the facing area In other words, it is possible to obtain a capacitance that corresponds to the liquid level height of the content liquid.

The difference in capacitance depending on the liquid level is due to the difference in capacitance between the sensor 127 and the microcontroller 7121 of the control circuit 82, as shown in Part 6.
By connecting via the D converter 128, the microcomputer 121
I am trying to input it into . For this, Yori microcomputer 121
determines the level of the liquid content manually according to the difference in capacitance.

This determination result is determined by each LHD 131 to
Out of 137, the number corresponding to the liquid amount is displayed by lighting up. The LED 131 at the bottom is lit to prompt water supply when the liquid level drops to a level that requires water supply, and has a color and brightness that makes it more noticeable than the others. Also, at this time, the buzzer 143 sounds.

Note that in order to determine the liquid level, it is easy to prepare a table of the relationship between capacitance and liquid level in necessary stages, and to 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 kettle heater 3b, connected to a heater drive circuit 141, and controlled by relays RYI and RY2 of a control circuit 82. For this reason, relays RYI, R
Contacts R-1 and R-2 of Y2 are connected to heaters 3a and 3b as shown in the figure. Relays RY1 and RY2 are transistors T that are turned on and off by signals from the microcomputer 121.
It is turned on and off by RI and TR2. Relay J
? When YI is turned on, relay contacts R-1 are turned on, turning on the heat retaining heater 3a, and when relay RY2 is turned on, relay contact R-2 is turned on, turning on the water boiling heater 3b. By controlling both heaters 3a and 3b to be energized simultaneously, the content liquid can be boiled to boiling point, and by controlling the energization to only the warming heater 3a, the content liquid can be heated to maintain a predetermined temperature before boiling. It is designed to keep you warm.

Electricity is turned on in the boiling state when the temperature of the liquid content detected by the temperature sensor 142 (Fig. 3) is lower than the keep-warm temperature and requires boiling, and when the re-boiling operation unit 8 is turned on in the keep-warm state.
0 is turned on, and the temperature sensor 142 is
When the temperature is detected, it will return to the warm state.

The energization in the heat-retaining state is such that the heat-retaining heater 3a is energized while the temperature sensor 142 detects a temperature below a predetermined heat-retaining temperature, and when the predetermined heat-retaining temperature is detected, the energization of the heat-retaining heater 3a is stopped. For these controls, the temperature sensor 142 is also connected to the A/D conversion circuit 12.
8 to the microcomputer 121.

Further, under the control of the microcomputer 121, each time the reboiling operation section 80 is turned on on the operation surface 5, the heat retention display section 75 and the reboiling display section 74 are individually lit in sequence, and the display section that remains lit for a predetermined time or more The corresponding mode is set and executed. However, if the reboiling operation section 80 is operated again, the setting of the operation mode can be changed in the same manner as described above.

In addition, a timer set operation section 76, a descaling operation section 77
, exit/exit operation section 78 , hot water output operation section 79 , reboiling operation section 80
Each of the microcontroller 121 has a switch operation section 129.
connected via. Each time the timer set operation section 76 is turned on on the operation surface 5, the display on the timer display section 72 is sequentially turned on in a rotary manner, and a timer is set for the time corresponding to the last turned on LED.

This timer setting time is such that, for example, the water boiling operation starts automatically while the user goes out or goes to bed, and after the set time elapses, the content liquid is obtained which has just finished boiling. .

To achieve this, the microcomputer 121 uses the sensor 127
By using information such as the liquid volume information from the boiler, the room temperature, or the temperature rise or fall characteristics when the liquid is heated or stopped, the liquid currently in the liquid can be boiled at exactly the set time. Calculations are performed to determine how far in advance heating needs to start. It is advisable to use a table created in advance for this calculation as well.

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

First, it is determined whether descaling has been selected by the descaling operation section 77 (step #1). If not, the content liquid is less than 80"C; if boiling has been selected by the reboiling operation section 80 (step #1). #2, #3)
Then, the process moves to step #5 and a boiling operation is performed. If scale removal is selected in step #1, scale removal F is set to 'bi' (step #4), and then the boiling operation is performed in step #5.

When it is determined in step #6 that boiling has ended, the process moves to step #7, and it is determined whether scale removal F is "1". When the boiling operation starts from step #2 or #3, since the descaling F is not "1", the process moves to step #8, and after the boiling operation is completed and the boiling is notified by the buzzer 143,
Switches to keep warm operation. Here, the boiling operation from step #2 corresponds to initial boiling due to water supply or water replenishment, but the boiling operation from step #3 corresponds to re-boiling, which is a warming operation after boiling. The temperature change of the content liquid in these cases is as shown in FIG. 8(a).

If scale removal F is "1" in step #7, the process moves to step #10, where the water heater 3b is turned off and an internal timer is started. When the timer counts 3 minutes, the timer is reset (steps #11, #12), and in step #13, the water heater 3b is turned on again and the timer is started. When the timer counts 1 minute, reset the timer (Steps #14 and #15)
, In step #16, the water heater 3b is turned off and a timer is started. When the timer counts 3 minutes, reset the timer. Step #17, #1
8) In step #19, turn on the water heater 3b and start the timer. When the timer counts 1 minute, reset the timer (steps #20 and #21)
). Therefore, as shown in Figure 8, after the initial boiling, the water heater 3b is turned on every 3 minutes to re-boil the water for 1 minute each, so the initial boiling and the second re-boiling are performed twice. It is possible to vigorously release chlorine compounds, etc. in the content liquid, and since the content liquid remains at a high temperature for a predetermined period of time after initial boiling and each reboiling, it is possible to promote the release of emitted substances. . It sufficiently exhibits the so-called scale removal effect, and since boiling does not continue, there is no problem of excessive temperature rise.

When the above descaling operation is completed, step #22
Then, the scale removal F is reset to "0" and the process returns to step #8. The temperature change of the content liquid in the Naoriki removal operation mode is as shown in FIG. 8(b). It is also possible to continue boiling for a predetermined period of time in order to remove the liquid.

The motors 51 and 62 are also connected to the microcomputer 121 via the motor drive circuit 141, and are connected to the spout ejection/retraction operation section 78.
It is controlled to move in and out of the spout pipe 49 and to dispense hot water in accordance with the operation of the hot water tapping operation unit 79.

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

FIG. 9 shows the exit/exit operation processing subroutine. When the spout egress/retreat operation unit 78 is operated, it is determined whether the protrusion F is O or not. When the value is 0, the spout pipe 49 is not projected to the spouting position. At this time, the protrusion F is set to 1, the timer A is started, and the motor 62 is turned on for forward rotation. As a result, the spout pipe 49 is moved from the storage position to the spouting position. When the timer A ends, the spout pipe 49 has reached the spouting position, and the motor 62 is turned off after waiting for the timer to end. Next, the pouring position F is set and the process returns (steps #31 to #38).

When the spout ejection/retraction operation section 78 is operated next, the protrusion F
If is not 0, the spout pipe 49 is in the spouting position, so
Since this is an operation for retracting this to the storage position, the protrusion F timer B is started and the motor 62 is turned on in reverse. As a result, the spout pipe 49 is retreated from the spouting position to the storage position. When the timer B ends, the spout pipe 49 has reached the storage position, and the motor 62 is turned off to stop the spout pipe 49 at the storage position. Next, the protrusion F and the pouring position F are reset to 0 and the process returns (steps #31, #3
2, #41 to #46).

FIG. 10 shows the hot water tapping operation processing subroutine. When the hot water tapping operation section 79 is operated, it is determined whether the pouring position F is 1 or not. This is to determine whether or not the spout pipe 49 is at the spouting position. Control is advanced so that hot water can be tapped only when the spout pipe 49 is at the spouting position, and the motor 51 is turned on (steps #51 to #53). At the same time, a time counter is started, and this count continues as long as the hot water tapping operation section 79 continues to be operated. This continuation is such that the motor 51 is set to a medium speed until the time reaches 4 seconds, so that the motor 51 is rotated at a medium speed. Also, if the continuation exceeds 4 seconds, the motor 5
1 is set to high speed so that the motor 51 is rotated at high speed. When the operation of the hot water tapping operation section 79 is completed, the motor 51 is turned off and the process returns (steps #54 to #59).

As a result, hot water is tapped only when the spout pipe 49 is in the pouring position and while the hot water tap operation section 79 is being operated, thereby ensuring safety in use. If the hot water dispensing operation continues for 4 seconds or more, the amount of hot water dispensed per unit time can be increased, and the time required for dispensing a large amount of hot water can be shortened.

FIG. 11 shows a second embodiment of the invention. In this embodiment, the spout pipe 49 is slidably fitted onto a horizontally bent guide pipe 141 at the upper end of the vertically oriented pipe 46, so that it can be moved in and out. A passive piece 142 is integrally formed at the base of the spout pipe 49, and one end of an intermediary lever 143 is fitted into a passive hole 142a of the passive piece 142. The middle part of the intermediate lever 143 is connected to the shaft 1.
44, and the other end is directly connected to the motor 62.
is engaged with the bifurcated portion 61a. As a result, the motor 62
When rotated in the normal direction, the spout pipe 49 is projected through the arm 61 and the intermediate lever 143 to the spouting position shown by the imaginary line in the figure. Further, when the motor 62 is reversely rotated, the spout pipe 49 is retreated to the retracted position shown by the solid line in the figure.

The present invention is not limited to the above embodiments, but can be implemented in various ways. For example, the egress and retraction of the spout pipe can be absorbed by a flexible expansion/contraction section in the middle of the outlet path, and the specific mechanisms for egress/retraction movement and egress/retraction drive can be designed in various ways.

Further, the electric dispensing mechanism for dispensing the content liquid electrically can be changed over time, such as by adopting a pressurized dispensing mechanism.

(Effects of the Invention) According to the present invention, the content liquid is automatically poured out through the outlet path by the action of the electric pump, and the outlet path for this pouring is normally inside the container when no pouring is performed. By setting it in the retracted storage position, it is possible to prevent it from protruding to the outer surface of the container body, and the lead-out path can be projected out of the container body from the storage position by appropriate operation of the electric mechanism by the operating means. The content liquid can be poured out automatically by a simple operation unrelated to the state in which it does not protrude from the outer surface of the container body, and furthermore, the outlet path is operated by an electric mechanism operated by an operating means. By the appropriate action of
Since the liquid container can be stored automatically from the dispensing position to the storing position, and therefore reliably regardless of the shape of the outlet path, the external shape and dispensing operation of a liquid container with an electric dispensing device are simplified, Combined with the electric dispensing function, both operability and appearance are improved.

Furthermore, even if the operating means for dispensing the liquid content is operated, the operation is not valid unless the outlet channel is in the dispensing position, and the liquid content is dispensed even though the outlet channel is not in the dispensing position. Since such situations can be avoided, there is no inconvenience such as the content liquid being poured out even though the outlet channel is in the storage position or on the way to the dispensing position, ensuring safe use. be able to.
