Description

  The present invention relates to a liquid tank and a cooking device.

  Conventionally, as a liquid tank, there exists a water supply tank mounted in a heating cooker, as disclosed by Unexamined-Japanese-Patent No. 2008-70137 (patent document 1). The water in this water supply tank is sent to a steam generator by a water supply pump to become saturated water vapor.

  As shown in FIG. 12, the water supply tank includes a tank body 1001 for storing water. A joint portion 1002 for sending water to the steam generator is provided below the tank main body 1001. The joint portion 1002 has a cylindrical shape, and the space in the joint portion 1002 communicates with the space in the tank main body 1001 through the through hole 1003.

  The through hole 1003 is opened and closed by a valve body 1004. The valve body 1004 has a valve body main body portion 1005 and a shaft portion 1006 connected to the valve body main body portion 1005, and is biased toward the joint portion 1002 by a coil spring 1007. The shaft portion 1006 is inserted into the through hole 1003 so as to be movable back and forth in the axial direction, and most of the shaft portion 1006 is in the joint portion 1002 when the through hole 1003 is closed. Further, at the end of the shaft 1006 opposite to the valve body main body 1005 side, four protrusions 1008,... (Only 2 appear in FIG. 12) are provided at 90 ° intervals in the circumferential direction. Yes. For this reason, the end portion of the shaft portion 1006 opposite to the valve body main body portion 1005 side looks substantially cross-shaped when viewed from the axial direction.

  When such a water supply tank is attached to the casing of the heating cooker, the valve body 1004 moves to the right in the figure against the urging force of the coil spring 1007. Thereby, the valve body main body 1005 is separated from the peripheral edge of the through hole 1003, and the water in the tank main body 1001 flows out of the joint 1002 through the through hole 1003.

  On the other hand, when the water supply tank is removed from the casing, the valve body 1004 moves to the left in the figure by the urging force of the coil spring 1007. As a result, the valve body main body 1005 abuts on the peripheral edge of the through hole 1003, and water cannot pass through the through hole 1003.

  By the way, in the said water supply tank, in order to enlarge the flow volume of the water in the joint part 1002, the volume of the space between the joint part 1002 and the axial part 1006, ie, the volume of the joint part 1002, is enlarged. For this reason, a lot of water remains in the joint portion 1002 when the water supply tank is removed.

  Therefore, when the water supply tank is detached from the casing and carried, there is a problem that the remaining water in the joint portion 1002 falls on the table or floor and the table or floor gets wet.

JP 2008-70137 A

  Then, the subject of this invention is providing the liquid tank which can reduce the surrounding wetness, and a heating cooker provided with the same.

In order to solve the above problems, the liquid tank of the present invention is
A tank body for storing liquid;
A cylindrical portion provided in the tank body;
A through hole provided in the tank body so that a space in the tank body communicates with a space in the cylindrical portion;
A valve body for opening and closing the through hole;
An urging portion for urging the valve body toward the peripheral edge side of the through-hole,
The valve body is
A shaft portion inserted through the through hole so as to be able to advance and retreat in the central axis direction of the cylindrical portion,
A valve body main body portion that is continuous with the end of the shaft portion inside the tank main body, can be advanced and retracted in the direction of the central axis of the cylindrical portion, and can be in close contact with the peripheral edge portion of the through hole;
The shaft portion has an approximately cylindrical or substantially columnar liquid push-out portion that is connected to an end portion of the shaft body outside the tank body and is accommodated in the cylinder portion so as to be movable back and forth in the central axis direction of the cylinder portion. It is a feature.

  According to the liquid tank having the above configuration, when the valve body main body moves backward against the urging force of the urging portion and is separated from the peripheral portion of the through hole, the liquid in the tank main body passes through the through hole. It flows out from the tube. On the other hand, when the valve body main body advances by the urging force of the urging portion and contacts the peripheral edge of the through hole, the outflow of the liquid in the tank main body stops. At this time, the liquid push-out portion moves forward in the tube portion and pushes the liquid in the tube portion out of the tube portion.

  Therefore, even if the user carries the tank body after stopping the outflow of the liquid in the tank body, the remaining amount of the liquid in the cylinder portion is small, so that the surrounding wetness can be reduced.

  In addition, since the liquid push-out portion has a substantially cylindrical shape or a substantially columnar shape, the volume of the tube portion can be reduced, and the remaining amount of liquid in the tube portion can be further reduced.

In one embodiment of the liquid tank,
The space in the cylinder part is widened toward the tank body side.

  According to the liquid tank of the above embodiment, the liquid push-out part moves backward and approaches the tank body as the through hole is opened. At this time, since the space in the cylinder part is widened toward the tank main body, the space between the cylinder part and the liquid extrusion part is increased.

  Therefore, it is possible to prevent the liquid flow rate in the cylindrical portion from decreasing.

  On the other hand, with the closing of the through hole, the liquid pushing portion moves forward and moves away from the tank body. At this time, since the space in the cylinder part is widened toward the tank body side, the space between the cylinder part and the liquid extrusion part is reduced.

  Therefore, even if the liquid in the cylinder portion remains after the valve body is closed, it is difficult for the liquid to leak from the cylinder portion.

In one embodiment of the liquid tank,
The shaft part is provided with a rib extending in the axial direction,
The rib faces the inner peripheral surface of the through hole when the through hole is opened.

  According to the liquid tank of the above embodiment, when the through hole is opened, the rib extending in the axial direction faces the inner peripheral surface of the through hole, so that the gap between the shaft portion and the through hole is kept substantially constant. It is possible to prevent the liquid flow rate in the cylindrical portion from greatly fluctuating.

In one embodiment of the liquid tank,
The shaft portion has a thick portion thicker than a portion where the rib is provided on at least one side of the rib in the axial direction.

  According to the liquid tank of the above embodiment, since there is a thick part thicker than the part where the rib is provided on at least one side of the rib in the axial direction, the volume of the cylinder part is reduced, and the liquid in the cylinder part is reduced. The remaining amount of can be further reduced.

In one embodiment of the liquid tank,
The said cylinder part is a substantially cylindrical shape.

  According to the liquid tank of the above embodiment, since the cylindrical portion is substantially cylindrical, the gap between the cylindrical portion and the liquid pushing portion is substantially circular when the valve body is closed.

  Therefore, even if the liquid in the cylinder portion remains after the valve body is closed, the liquid is difficult to leak from the cylinder portion due to surface tension.

The heating cooker of the present invention is
A casing,
The liquid tank of the present invention detachably attached to the casing;
A vapor generator for evaporating the liquid from the liquid tank to generate vapor;
And a heating cabinet for heating an object to be heated using the steam generated by the steam generator.

  According to the cooking device having the above-described configuration, the wetness of the surroundings can be reduced by providing the liquid tank. Therefore, for example, the user can be prevented from slipping and getting hurt on the wet floor.

  According to the liquid tank of the present invention, the valve body has the substantially cylindrical or substantially columnar liquid extrusion portion accommodated in the cylinder portion so as to be capable of moving back and forth in the central axis direction of the cylinder portion. The liquid in the cylinder part is pushed out of the cylinder part by moving forward in the part.

  Therefore, the remaining amount of the liquid in the cylindrical portion is reduced, so that the degree of wetness when the tank body is carried can be reduced.

  The dew receptacle 4 is a container that can be attached to and detached from the two front legs 6 and 6. The front legs 6 and 6 are provided on the front side of the bottom of the casing 1. When the dew receptacle 4 is attached to the front legs 6, 6, a part of the dew receptacle 4 is positioned below the rear surface (surface on the casing 1 side) of the door 2 with a handle when closed.

  FIG. 2 is a schematic perspective view of the heating cooker from which the top and both sides of the casing 1 are removed as viewed from the front obliquely upward. Moreover, FIG. 3 is the schematic perspective view which looked at the heating cooker of FIG. 2 from back diagonally upward.

  In the casing 1, as shown in FIGS. 2 and 3, a heating chamber 8 that houses an object to be heated such as fish or meat is installed. In the casing 1, a space on the side of the heating chamber 8 and behind the operation panel 3 is an electrical component chamber 9, and a space behind the heating chamber 8 and behind the electrical component chamber 9 is an intake space 10. That is, the electrical component chamber 9 is provided on one side of the casing 1, while the intake space 10 is provided on the rear side of the casing 1. Further, on the rear surface of the casing 1, opaque containers 101A and 101B having a substantially container shape are detachably attached. The height of the spacer 101 </ b> A with respect to the rear surface of the casing 1 is substantially the same as the height of the spacer 101 </ b> B with respect to the rear surface of the casing 1.

  The heating chamber 8 has an opening 8a (see FIG. 5) on the front side, and the door 2 with a handle opens and closes the opening 8a. The object to be heated is placed on a tray 40 which will be described later, and passes through the opening 8a of the heating chamber 8 together with the tray. Further, heat shield plates 11, 11,... Are arranged above, below, behind and on both sides of the heating chamber 8. That is, the heat shield plates 11, 11,... Are arranged around the heating chamber 8 except for the opening 8 a. Although not shown, the space between the heat shield plate 11 and the heating chamber 8 is filled with a heat insulating material. The gas in the heating chamber 8 is guided to the front side of the casing 1 through the exhaust path 12 and is exhausted from the front side of the casing 1 to the outside of the casing 1.

  In the electrical component chamber 9, a steam generator 13 for generating saturated steam, a water supply pump 14 connected to the steam generator 13 via a water supply tube 20, and a front of the water supply pump 14 are arranged. There is a tank storage section 15. When the object to be heated is heated, air from the cooling fan 16 flows through the electrical component chamber 9 so that electrical components such as the water supply pump 14 can be cooled.

  The intake space 10 is a space through which air around the rear side of the casing 1 flows from the four intake ports 17A, 17B, 17C, and 17D when the cooling fan 16 is driven. The air in the intake space 10 is sucked into the cooling fan 16 and blown out into the electrical component chamber 9. The intake ports 17A, 17B, 17C, and 17D are each configured by a plurality of slits provided at the rear portion of the casing 1.

  The exhaust path 12 includes a flexible synthetic resin exhaust tube 18 and a non-flexible synthetic resin exhaust duct 19 disposed on the side of the tank housing 15.

  The exhaust tube 18 is installed so as to extend from the upper rear side to the lower front side of the electrical component chamber 9. The rear end portion of the exhaust tube 18 is connected to the rear portion of the heating chamber 8, while the front end portion of the exhaust tube 18 is connected to the exhaust duct 19.

  The rear end of the exhaust duct 19 is open so that air from the cooling fan 16 flows into the exhaust duct 19. The gas from the inside of the heating chamber 8 is mixed with the air from the cooling fan 16 and the temperature is lowered.

  2 and 3 denotes a partition wall that partitions the electrical component chamber 9 and the intake space 10. A cooling fan 16 is attached to the partition wall 21.

  FIG. 4 is a schematic view of the cooking device of FIG. 2 as viewed from the side.

  An exhaust / drain port 22 is provided at the bottom of the front side of the exhaust duct 19. The exhaust / drain port 22 passes through the bottom of the casing 1 and faces the dew receiver 4. Further, the exhaust duct 19 has a front end portion of the exhaust tube 18, and the opening of the front end portion of the exhaust tube 18 faces the exhaust and drain port 22 side. Condensed water generated in the exhaust tube 18 and the exhaust duct 19 can be drained to the dew receptacle 4 through the exhaust / drain port 22.

  FIG. 5 is a schematic perspective view showing a state where the handle-equipped door 2 is pulled out in FIG.

  The tank storage unit 15 stores a water supply tank 23. When the door 2 with a handle is pulled out, the front end portion of the water supply tank 23 is exposed, so that the user can pull out the water supply tank 23 from the tank storage portion 15. When the door 2 with a handle is pulled out, the tray 40 connected to the door 2 with a handle is also pulled out from the heating chamber 8. The water supply tank 23 is an example of a liquid tank.

  The water in the water supply tank 23 is supplied to the steam generator 13 through the water supply tube 20 by driving the water supply pump 14. The steam generator 13 heats water from the feed water pump 14 with a steam generating heater 24 (see FIG. 4) to generate saturated steam.

  When viewed from the electrical component room 9 side, the steam generating heater 24 has a shape in which a U-shape is rotated 90 degrees clockwise. Most of the steam generating heater 24 is embedded in the wall portion of the steam generating device 13.

  Below the tray 40 is a tray holder 44 that detachably holds the tray 40. The tray holder 44 is formed by bending a metal wire into a predetermined shape. The front end of the tray holder 44 is detachably attached to the rear surface of the door 2 with a handle. Thereby, the tray 40 can move in the front-rear direction together with the door 2 with the handle.

  The door with handle 2 slides in the front-rear direction with a pair of rail units 41 and 41 (in FIG. 5, only one rail unit 41 appears and the other rail unit is hidden by the tray 40). Open and close the opening 8a.

  FIG. 6A is a schematic view of the water supply tank 23 viewed from the right side. Moreover, FIG. 6B is the schematic which looked at the said water supply tank 23 from the upper surface side. Moreover, FIG. 6C is the schematic which looked at the said water supply tank 23 from the rear surface side. Moreover, FIG. 6D is the schematic which looked at the said water supply tank 23 from the front side.

  As shown in FIGS. 6A to 6D, the water supply tank 23 includes a tank body 61 and a lid 62 detachably attached to the upper end portion of the tank body 61.

  The tank body 61 includes a water storage chamber 63 for storing water, a substantially cylindrical joint portion 64, a handle opening 65 that opens on the upper surface side, and a water filling opening that opens on the upper surface side. 66 and a through hole 67 are provided. The opening edge of the through hole 67 has a substantially circular shape. The joint part 64 is an example of a cylindrical part.

  Water in the water storage chamber 63 can flow into the joint portion 64 through the through hole 67. That is, the space in the water storage chamber 63 can communicate with the space in the joint portion 64 through the through hole 67.

  The opening 65 is located in front of the opening 66. A partition plate portion 67 is disposed in the opening 65. There is a gap on both sides of the partition body portion 67, and for example, water that has entered the opening 65 falls downward from the gap. The user puts a finger into the opening 65 and pulls out the water supply tank 23 from the tank storage unit 15.

  The opening 66 is opened and closed by a lid 62, and the user fills the water storage chamber 63 with water from the opening 66.

  The through hole 67 is opened and closed by a valve body 68. The valve body 68 is urged toward the joint portion 64 by a coil spring 69 and is in close contact with the peripheral portion of the through hole 67 on the water storage chamber 63 side. The coil spring 69 is an example of an urging unit.

  Note that reference numeral 90 in FIGS. 6A and 6B denotes a seal member. This shielding board 90 seals between the outer peripheral surface of the joint part 64 and the inner peripheral surface of the connection part 81 mentioned later.

  FIG. 7 is a schematic perspective view of the valve body 68 as viewed from the water pushing portion 72 side.

  As shown in FIGS. 6A, 6C, and 7, the valve body 68 includes a shaft portion 70, a substantially disc-shaped valve body main body 71 connected to one end portion of the shaft portion 70, and a shaft portion thereof. A substantially cylindrical water extruding portion 72 connected to the other end portion of 70. Here, the one end portion of the shaft portion 70 is disposed inside the tank main body 61, and the tank storage portion 15 is an end portion located on the front side when the water supply tank 23 is stored. The other end portion of the shaft portion 70 is disposed outside the tank main body 61, and the tank storage portion 15 is an end portion located on the rear side when the water supply tank 23 is stored. The water extruding unit 72 is an example of a liquid extruding unit.

  The shaft portion 70 is inserted through the through hole 67 and can be advanced and retracted in the direction of the central axis of the joint portion 64. Further, four ribs 73, 73, 73, 73 (only three appear in FIG. 7) are provided at a substantially central portion in the axial direction of the shaft portion 70 at intervals of 90 ° in the circumferential direction. Each rib 73 extends in the axial direction, and a recess 74 exists between the ribs 73. And the axial part 70 has thick part 70a, 70a thicker than the part in which the rib 73, 73, 73, 73 is provided in the both sides of the axial direction of the rib 73. As shown in FIG. That is, the thick portions 70 a and 70 a are formed so that the outer diameter is larger than the outer diameter of the recess 74.

  The said valve body main-body part 71 consists of a disk-shaped plastic part and the rubber part which covers this plastic part. The valve body main body 71 can advance and retreat in the central axis direction of the joint portion 64 and can be brought into close contact with the peripheral edge of the through hole 67. In FIG. 7, only the plastic part is shown, and the rubber part is not shown.

  The water extruding part 72 is accommodated in the joint part 64 so as to be able to advance and retreat in the central axis direction of the joint part 64. Further, a step portion is provided on the inner peripheral surface of the water extrusion portion 72, and the other end portion of the shaft portion 70 is locked to the step portion.

  According to the heating cooker having the above configuration, when the user inserts the water supply tank 23 into the tank housing part 15, as shown in FIG. 8, the connection part 81 provided at the upstream end of the water supply path 80 is provided. A part of the joint part 64 enters. A projection 82 is provided in the connection portion 81 so as to face the valve body 68 from the axial direction. Further, the length of the protrusion 82 in the vertical direction is longer than the inner diameter of the water extruding portion 72 and shorter than the outer diameter of the water extruding portion 72. For this reason, when the water supply tank 23 is further advanced to the rear side, as shown in FIG. 9, the protrusion 82 comes into contact with the rear end surface of the water pushing portion 72, so that the valve body 68 cannot be advanced rearward. Since the protrusion 82 does not contact the rear end surface of the portion 64, the joint portion 64 advances to the rear side. That is, the valve body main body 71 moves backward against the urging force of the coil spring 69 with respect to the joint portion 64.

  As a result, the valve body main body 71 is separated from the peripheral portion of the through hole 67, and the water in the water storage chamber 63 flows out from the joint portion 64 through the through hole 67. More specifically, the water in the water storage chamber 63 is between the peripheral portion of the through hole 67 and the valve body main body 71, between the inner peripheral surface of the through hole 67 and the concave portion 74, and in the water extrusion portion 72. It flows between the outer peripheral surface and the inner peripheral surface of the joint portion 64 and enters the connection portion 81, and is guided to the water supply pump 14 by the water supply passage 80.

  On the other hand, when the user pulls out the water supply tank 23 from the tank storage portion 15, the valve body main body portion 71 moves forward with respect to the joint portion 64 by the biasing force of the coil spring 69. Then, the valve body main body 71 comes into contact with the peripheral edge of the through hole 67 and the outflow of water in the water storage chamber 63 is stopped. At this time, the substantially cylindrical water extruding part 72 moves forward in the joint part 64 and pushes the water in the joint part 64 out of the joint part 64.

  Therefore, even if the user carries the tank body 61 after stopping the outflow of water in the water storage chamber 63, the remaining amount of water in the joint portion 64 is small, so that the surrounding wetness can be reduced.

  Further, since the water extruding portion 72 has a substantially cylindrical shape, the volume of the joint portion 64 can be reduced and the remaining amount of water in the joint portion 64 can be further reduced.

  Further, since the thick portions 70a and 70a which are thicker than the portion where the rib 73 is provided are provided on both sides in the axial direction of the rib 73, the volume of the joint portion 64 is further reduced, The remaining amount of water can be further reduced.

  Further, since the joint portion 64 has a substantially cylindrical shape, when the valve body 68 is closed, as shown in FIG. 6C, the gap between the joint portion 64 and the water extrusion portion 72 becomes a substantially circular shape.

  Therefore, even if water in the joint part 64 remains after the valve body 68 is closed, the water is difficult to leak out from the joint part 64 due to surface tension.

  Further, when the valve body 68 is opened, the rib 73 extending in the axial direction faces the inner peripheral surface of the through hole 67 as shown in FIG. 10 (for the sake of clarity, illustration of the joint portion 64 and the coil spring 69 is omitted). Therefore, the distance L1 between the bottom surface of the recess 74 and the inner peripheral surface of the through hole 67 is kept substantially constant.

  Therefore, it is possible to prevent the flow rate of water at the joint portion 64 from fluctuating greatly.

  The time when the valve body 68 is opened refers to the time when the valve body main body 71 is separated from the peripheral edge portion of the through hole 67 and the water in the water storage chamber 63 is in a state of being able to pass through the through hole 67. .

  By the way, the flow rate of water entering the joint portion 64 from the water storage chamber 63 is determined by the distance L1. For this reason, the distance L2 between the side surface of the concave portion 74 and the inner peripheral edge portion of the through hole 67 and the distance L3 between the side surface of the concave portion 74 and the outer peripheral edge portion of the through hole 67 are larger than the distance L1. Even so, the flow rate of water entering the joint 64 from the water storage chamber 63 does not increase.

  Therefore, in the present embodiment, the distance L1 is substantially the same as the distance L2 between the side surface of the recess 74 and the inner peripheral edge of the through hole 67, and the outer peripheral edge of the side surface of the concave 74 and the through hole 67. Is substantially the same as the distance L3.

  Therefore, the volume of the thick portions 70a, 70a can be maximized, and the volume of the joint portion 64 can be greatly reduced.

  Moreover, since the surrounding wetness can be reduced by the water supply tank 23 as described above, for example, the user can be prevented from slipping and getting hurt on the wet floor.

  In the above embodiment, the substantially cylindrical joint portion 64 is provided in the tank main body 61. However, for example, a substantially square cylindrical joint portion may be provided as an example of the cylindrical portion.

  In the above-described embodiment, a thick portion thicker than a portion where the rib 73 is provided may be provided only on one side of the rib 73 in the axial direction.

  In the above embodiment, instead of the substantially cylindrical water extruding portion 72, a substantially cylindrical water extruding portion may be used.

  In the above embodiment, the joint body 164 shown in FIG. The space in the joint portion 164 is widened toward the tank body 61 side.

  Therefore, when the valve body 68 is opened, the gap between the rear end of the joint part 164 and the water push-out part 72 is increased, so that the flow rate of the liquid in the joint part 164 can be prevented from decreasing.

  Further, when the valve body 68 is closed, the space between the joint portion 164 and the water push-out portion 72 becomes small, so that it is possible to prevent water from leaking from the inside of the joint portion 164.

  In FIG. 11, the same components as those shown in FIG. 6A are denoted by the same reference numerals as those in FIG. 6A, and description thereof is omitted. The time when the valve body 68 is closed refers to a time when the valve body main body 71 is in close contact with the peripheral edge of the through hole 67 and the water in the water storage chamber 63 cannot pass through the through hole 67.

  As the liquid tank of the present invention, there is a liquid tank that supplies a liquid other than water (for example, kerosene) in addition to a liquid tank that supplies water.

  Examples of the cooking device of the present invention include not only an oven that uses superheated steam, but also an oven range that uses superheated steam, an oven that does not use superheated steam, and an oven range that does not use superheated steam.

  In the cooking device of the present invention, healthy cooking is performed by using superheated steam or saturated steam in cooking heaters (including those using an electric stove or gas stove such as an IH heater or electric heater) or a microwave oven. Can do. For example, in the cooking device of the present invention, superheated steam or saturated steam having a temperature of 100 ° C. or higher is supplied to the food surface, and the superheated steam or saturated steam adhered to the food surface is condensed to give a large amount of condensation latent heat to the food. So it can efficiently transfer heat to food. Moreover, when condensed water adheres to the food surface and salt and oil are dropped together with condensed water, salt and oil in the food can be reduced. Further, the inside of the heating chamber is filled with superheated steam or saturated steam, and becomes anoxic state, thereby enabling cooking while suppressing oxidation of food.
