Further, the steam is introduced into the pan cooking chamber through the steam conduit, the food comes into direct contact with the high temperature steam, and the heat is more sufficiently received. Hereinafter, the specific technical solutions of the present invention will be further described with reference to some embodiments.

Embodiment 1
1 to 3, the steam heating cooker according to the first embodiment of the present invention includes a body and a pot 200, the body has a body 100 and a head 110, and the head 110 is reversible. It is provided on the body 100, the head 110 is provided on the body 100, the pedestal 120 is included on the lower part of the body 100, and the pot 200 is placed on the pedestal 120, and between the head 110 and the pedestal 120. An open space for accommodating the pan 200 is formed, and the head 110 and the body 100 are connected via a rotation limit device. The rotation limit device has a first working position in which the head 110 abuts on the pan 200 and a pan. It is limited so that it can be reversed and switched between 200 and the second working position to be separated.

  Specifically, a steam generator 150 (for example, a water storage type boiler, an instant boiler, etc.) and a water pump 140 are provided inside the body 100 of the present embodiment, and a water tank 130 is provided on one side of the body 100. When the water pump 140 is operated, the water in the water tank 130 is sent to the steam generator 150, and the head 110 is provided with the steam output port 111. The hose 700 communicates with each other. The pot 200 of the present embodiment includes a pot body 220 and a lid 210. The lid 210 is covered by the pot body to form a cooking chamber, and the pot 200 is in a state where the lid 210 is covered by the pot body 220. When the pan 200 is placed on the pedestal 120 and cooking is completed, and the pan 200 is taken out, the lid 210 is still kept covered by the pan body 220, thus reducing the heat loss and reducing the pan 200. After leaving the body 100, a long heat retention time is maintained, the lid 210 is provided with a steam injection hole 211, and the head 110 abuts against the pot 200. It refers to sealing and abutting with the injection hole 211, and when actually operating, the steam generator 150 heats water to generate steam, and the steam passes through the steam output port 111 and the steam injection hole 211. Te is introduced into the pot 200, it is used for heating food.

  The open space refers to an open space limited between the head 110 and the pedestal 120. In the horizontal direction, there is no limit except for the body 100 itself, and the distance of the head 110 to the pedestal 120 is the height of the open space. Since it is decided, the pan 200 is basically moved in and out of the pedestal 120 of the body 100 in a translational manner, and if the height of the open space is too small, the head 110 or the pedestal 120 may be touched when the pan 200 is taken in and out. , Leading to tilting or overturning of the pan 200, so that the user must hold the pan 200 more carefully. If the open space is enlarged by a method of increasing the height of the head 110, the problem of putting the pot in and out can be solved, but a part of the open space is wasted and the height of the main body is increased.

  The embodiment of the present invention proposes the idea of a rotary head, and the height of the open space is changed by the opening and closing movement of the head 110 in the height direction of the body 100, that is, the head 110 as described above. Is inverted and switched between a first working position in which the pot abuts the pot 200 and a second working position in which the pot 200 separates from the pot 200. When the pan 200 is put in and out, the head 110 is inverted from the first working position to the second working position, and the distance between the head 110 (the position where the head 110 abuts the pan 200) and the pedestal 120 increases, That is, the height of the open space is increased, thereby providing a larger space for loading and unloading the pan 200 and the freedom of loading and unloading the pan 200, so that the user can more conveniently load and unload the pan 200 when cooking. The head 110 is reversed from the second working position to the first working position and abuts against the pan 200, thus making it convenient to put the pan 200 in and out, and not to waste the open space.

  Referring to FIG. 3, in the embodiment of the present invention, the rotation limit device limits the reversal angle of the head 110 so that the head 110 can be reversed and switched only between the first working position and the second working position, By preventing the head 110 from being damaged due to being turned over too much, particularly by limiting the first working position of the head 110 and realizing the abutment of the head 110 and the pan 200, the head 110 presses the pan 200 too much. , Prevent the damage of the abutting parts of both. Preferably, in the embodiment of the present invention, when the head 110 is in the second working position, the included angle α with the horizontal plane is limited to 10 ° to 60 °, and the explanation is that the head 110 is the first working position. When the head 110 is in the horizontal position, the included angle α with the horizontal plane is the reversal angle of the head 110 limited by the rotation limit device when the head 110 is in the second working position. The head 110 at the first working position has a certain amount of floating up and down with respect to the horizontal state due to factors such as an error in part processing and a placement error. Therefore, the reversal angle of the head 110 limited by the rotation limit device is , And the included angle α with respect to the horizontal plane when the head 110 is in the second working position.

  According to the embodiments of the present invention, as will be understood, when the head 110 is in the second working position, the included angle with respect to the horizontal plane increases the open space after the head 110 is opened. When the possible height is determined and the included angle α with the horizontal plane is less than 10 ° when the head 110 is in the second working position, the rotation stroke of the head 110 is too small, and the difficulty of designing the rotation limit device is high. Not only does not increase the spatial advantage of the rotary head 110, but when the included angle α with the horizontal plane is larger than 60 ° when the head 110 is in the second working position, the operating environment Therefore, it is necessary to avoid the head 110 in the open state by preserving a large space above the cooking utensil, which leads to the limitation of the environment of use, and the rotation stroke that is too large can be manually operated by the user. Yo In addition, the steam generator 150 in the body 100 conveys the steam to the head 110 via the hose 700, and the steam is introduced into the pan 200 by the head 110, so that the first working position and the second working position can be achieved. When the included angle between and is less than 10 °, the reversal angle of the head 110 is too small, and it is difficult to mount the pan 200 sufficiently, and when the included angle between the first working position and the second working position is larger than 60 °, Since the reversal angle of the head 110 is large and the bending angle of the hose 700 at the reversal point between the head 110 and the body 100 is too large, the hose 700 may be damaged, and the joints at both ends of the hose 700 may receive force and come off. Easy to do. Therefore, according to the embodiment of the present invention, when the head 110 is in the second working position, the included angle α with the horizontal plane is limited to within a range of 10 ° to 60 °, and an excellent use experience is obtained while the lid is opened and closed. For convenient operation, the included angle α with the horizontal plane when the head 110 is in the second working position is 15 °, 20 °, 25 °, 30 °, 35 °, 60 ° depending on the actual product needs. May be

  Further, in some methods, the head is provided with a steam conduit for introducing inside the steam pan body, and in the process of reversing the head, the steam conduit rotates together with the head, and at this time, the reversal angle of the head is small, For example, below 45 °, the steam conduit has not escaped from the pan and the pan cannot be removed from the body. In the present embodiment, the pan 200 includes a pan body and a lid, and the lid is provided with a steam conduit (not shown), and steam is introduced into the foodstuff through the steam conduit and discharged, whereby the foodstuff is sufficiently supplied. Contact with steam to receive heat. Since the steam conduit is provided in the lid, when the head 110 is inverted, the steam conduit is not inverted together with the head 110, and when the head 110 is inverted within the range of 10 ° to 60 °, the pot 200 is not rotated. It does not affect the removal from 110.

  In the present embodiment, referring to FIG. 16, a body 100 is provided with a rotation shaft 500, and the head 110 is provided on the body so as to be inverted around the rotation shaft 500, so that the head 200 is abutted against the pan 200. Alternatively, the hose 700 is separated and the hose 700 is located below the rotating shaft 500. The head 110 is inverted about the axis of rotation 500 in the fuselage and abuts or separates from the pan 200. A hose 700 for carrying steam is provided below the rotary shaft 500, the bending point of the hose 700 is closer to the connecting line connecting both ends of the hose 700, and the head 110 is inverted around the rotary shaft 500. When the hose 700 is bent, the bending angle of the hose 700 becomes smaller, the width of deformation becomes smaller, the hose 700 is less likely to be cut or broken at the bent portion, and the life is extended. Further, the bending deformation of the hose 700 generates elasticity, and such elasticity adversely acts on joints at both ends of the hose 700, that is, joints with the steam ports in the hose 700 and joints with the steam generator 150 in the hose 700. However, when the joint is pulled to the outside and the joint receives the tensile force of the hose 700 itself for a long period of time, the joint of the hose 700 loosens and escapes, and a phenomenon of air leakage occurs, so that the hose 700 of the rotating shaft 500 is prevented. By arranging it downward, the bending width of the hose 700 is reduced, that is, the tensile force received by the joint of the hose 700 is reduced when the head 110 is inverted, and the joint of the hose 700 becomes loose and difficult to come off. ..

  The rotation limit device according to the embodiment of the present invention further drives the head 110 to reverse upward from the first working position to the second working position, and the head 110 is manually moved from the second working position to the first working position. A drive member is provided for permitting it to be inverted. The head 110 is reversed upward from the first working position to the second working position to realize opening of the head 110, and the head 110 is reversed downward from the second working position to the first working position to realize closing of the head 110. However, the opening of the head 110 provides power from the driving member, saves the user's operation, avoids the problem of steam burn, which is present when the user manually opens the head 110, and closes the head 110. Is realized by a method of manual operation such as pressing the head 110 by the user, and the cookware omits a member for providing power for closing the head 110, and the user can use the cover of the traditional rice cooker. Experience the steam-cooking cooker in an external pot with an operation method similar to opening and closing.

  The following provides a preferred embodiment of a rotation limit device according to an embodiment of the present invention, which is combined with FIGS. 4 and 5, wherein the rotation limit device is mounted on the limit plate 300 mounted on the head 110 and the body 100. The fixed holder 400 is provided with a limit shaft 410, the limit plate 300 is provided with a limit hole 310, and the limit hole 310 has a first limit end and a second limit end. When the shaft 410 moves to the first limit end, it limits the first working position and is locked to the first limit end, and when the limit shaft 410 moves to the second limit end, it limits the second working position. Specifically, the head 110 includes an upper lid 112 of the head and a lower lid 113 of the head, one end of the limit plate 300 is fixedly attached to the lower lid 113 of the head, and the other end of the limit plate 300 has an arc-shaped limit. A hole 310 is provided, the limit hole 310 including a guide section 312 of equal width and a limit section 311 having a width larger than the guide section 312, the upper end of the guide section 312 being the second limit end, and the limit section 311 being the guide section. It is located at the lower end of the section 312 and forms a first limit end, and the upper end of the fixed holder 400 is connected to the lower lid 113 of the head so as to rotate via the rotation shaft 500, and the head 110 is rotated around the rotation shaft 500. The fixed holder 400 is pierced in the lateral direction of the limit shaft 410 by rotating and closing the limit shaft 41. A first shift lever 420 is attached to one end of the head, and the other end of the limit shaft 410 is a flat shaft portion 411. The flat shaft portion 411 passes through the limit hole 310, and the position is limited by a locking spring. When the 110 rotates around the rotation axis 500 to open and close, the flat shaft portion 411 moves in the limit hole 310 to limit the rotation stroke of the head 110.

  In order to achieve the lock at the first limit end of the limit shaft 410, the fixed holder 400 of the present embodiment is provided with a first elastic lock member, and preferably, the first elastic lock member has one end fixed to the fixed holder 400. Is the first torsion spring 430 positioned at the other end of the first shift lever 420 or the limit shaft 410, and the first shift lever 420 and the limit shaft 410 rotate in association with each other. When the shift lever 420 is driven by an external force so as to rotate, the first torsion spring 430 is twisted to store force, and when the first torsion spring 430 releases elastic force, the limit shaft 410 is reversed. The width of the guide section 312 of the limit hole 310 is larger than the thickness of the flat shaft portion 411, but is smaller than the width of the flat shaft portion 411. When the flat shaft portion 411 moves to the limit section 311, the first torsion spring 430 releases elasticity. However, after the limit shaft 410 is rotated in the reverse direction and the flat shaft portion 411 is rotated by a certain angle, the guide shaft cannot enter the guide section 312, and the limit shaft 410 is locked by the limit section 311 of the limit hole 310 and can move. Instead, the head 110 is correspondingly locked in the first working position, as in the situation shown in FIGS.

  In order to achieve the unlocking of the limit shaft 410 at the first limit end, the fixed holder 400 is provided with a first unlock member controlled by an electric component, and the first unlock member is the first shift lever 420. The limit shaft 410 is driven to be rotated by the unlocking, and specifically, the electric component is the stepping motor 600 mounted on the fixed holder 400, and the rotation accuracy of the stepping motor 600 is high. The first unlocking member is the first dial 440 mounted on the output shaft of the stepping motor 600. When the head 110 is unlocked, the stepping motor 600 drives the first dial 440 to rotate, The first dial 440 toggles the first shift lever 420 to limit After rotating the flat shaft part 411 by a certain angle, the flat shaft part 411 enters the guide section 312, that is, the limit shaft 410 is unlocked, and the rotation limit device is further provided with a driving member. After unlocking the shaft 410, the drive member provides power, i.e., flips the head 110 upwards to the second working position, as in the condition shown in FIGS.

  Preferably, referring to FIGS. 6 and 8, the drive member of the present embodiment is a tension spring 600 having one end connected to the limit plate 300 and the other end connected to the fixed holder 400 or another portion of the main body. In the process of manually reversing the head 110 from the second working position to the first working position, the tension spring 600 is pulled and stores a force, and the head 110 is locked at the first working position. , The tendency of the head 110 to rotate to the second working position is maintained, and when the lock of the head 110 is released, the elasticity released from the tension spring 600 causes the head 110 to move upward from the first working position to the second working position. When the head 110 is driven so as to be reversed to the position, the user feels resistance by the driving member when the head 110 is pressed, and obtains an excellent feel of operation. In another embodiment, another elastic component such as a torsion spring may be adopted instead of the tension spring, and the torsion spring is fitted onto the rotary shaft so that one end is positioned on the head and the other end is positioned on the main body. Which serves the purpose of this embodiment as well.

  As can be seen from the above plan, the rotation limit device of the embodiment of the present invention has a locked state and an unlocked state, and the locked state is used to lock the head 110 in the first working position, and the drive member is unlocked. In the locked state, the head 110 is driven to reverse upward from the first working position to the second working position, and the advantages of such a design are as follows: during the cooking process, the head 110 ensures that the head 200 is cooked. It is possible to prevent the occurrence of problems such as air leakage at the abutting portion by ensuring that the head 110 swings abruptly, while ensuring a stable output of steam. For the heads of the above, the locked state allows the heads to be automatically locked when the user manually pushes the heads to the first working position, and Contributes to the determination of the closed position, the user avoids the repetition operations by the inability to confirm the closed position of the head, enhance the use experience.

In order to make the unlocking control of the rotation limit device convenient, the present embodiment proposes the following schemes:
1. The main body has a control module and a trigger module, and the trigger module is a physical key in the main body 100, for example, a mechanical switch, a button, a touch sensor type key, or the like. When the control module receives the trigger signal of the physical key, the stepper motor 600 is activated to complete the unlocking of the head 110, or the trigger module is used as a remote switch so that the user can operate the infrared remote controller. Remote control is realized, the trigger module may be a wireless communication module, and the mobile device (eg, mobile phone, tablet, smart watch / band, etc.) pushes activation information to realize remote control. Such a scheme allows the user to voluntarily select whether or not to open the head 110 according to the actual situation, and is highly flexible in use. As will be appreciated, the trigger module may be provided on the body, head or pedestal.

  2. The control module of the main body is arranged to activate the unlocked state of the rotation limit device directly or delayed when the cooking program is finished, that is, when the cooking program is finished, the control module of the program is It automatically sends a start command according to the setting, controls to start the stepping motor 600, completes the unlocking of the head 110, and by such a scheme, the product becomes more intelligent, and the main body is suitable. By omitting the physical key to realize the specific function, the external molding of the main body becomes more concise and aesthetic. If the unlocked state of the rotation limit device is activated in the delay, the pot has a certain period of natural cooling after cooking is completed, and the risk of burns due to steam is reduced.

  Referring to FIG. 9, the fixed holder 400 of the rotation limit device is further provided with a micro switch 460, and after the stepping motor 600 drives the first dial 440 to rotate, the limit shaft 410 is unlocked. , The first dial 440 moves the micro switch 460, and the stepping motor 600 continues to operate until the control module stops the operation of the stepping motor 600 in response to the trigger signal of the micro switch 460. As described above, the rotation angle of the limit shaft 410 is avoided when the first dial 440 avoids interfering with the rotation of the first shift lever 420 and the head 110 is manually inverted from the second working position to the first working position. By assuring that, the limit hole 311 is reliably locked in the limit section 311.

As described above, the principle of using the steam heating cooker according to the embodiment of the present invention is as follows:
Referring to FIGS. 6 and 7, the head 110 in this case is in the first working position, the limit shaft 410 is locked to the first limit end of the limit hole 310, and the drive member is in the state of storing force. 110 abuts the pan 200 and the cookware activates the cooking program or waits for the cooking program to finish and the head 110 to open.
When the stepping motor 600 receives the start command, the stepping motor 600 starts operating, the stepping motor 600 rotates the first dial 440, and the first dial 440 toggles the first shift lever 420, whereby the limit shaft 410 rotates at the same time. , The first torsion spring 430 is twisted to store a force, and the flat shaft portion 411 of the limit shaft 410 rotates a certain angle, and then enters the guide section 312, in which case the power provided from the driving member , The head 110 is driven so as to reverse upward from the first working position to the second working position, and the flat shaft portion 411 is moved along the guide section of the limit hole 310 to the limit as shown in FIGS. The head 110 is moved to the second limit end of the hole 310, and the head 110 (in the head 110, butts against the pan 200 in that state) is moved. The distance between the position) and the base is increased, increasing the height of the open space, thereby providing a degree of freedom out and out space larger pot and convenient loading and unloading of the pot.

  When the head 110 is closed again, the head 110 is inverted downward from the second work position to the first work position by a method such as a user manually pressing the head 110 so that the driving member stores force. And the limit shaft 410 enters the limit section 311 of the limit hole 310, the first torsion spring 430 releases elastic force to rotate the limit shaft 410, causing the flat shaft portion 411 of the limit shaft 410 to rotate at a constant angle. After rotating the, the guide section cannot be entered, the limit shaft 410 is locked in the limit section of the limit hole 310, cannot move and accordingly the head 110 waits for the next opening of the head. It is locked in the first working position.

Embodiment 2
10 and 11, unlike the first embodiment, the method of the present embodiment changes the locking and unlocking methods of the limit shaft 410, and specifically, as follows:
The rotation limit device includes a limit plate 300 and a fixed holder 400, one end of the limit plate 300 is fixedly attached to the lower lid 113 of the head, and a limit hole 310 is provided at the other end of the limit plate 300. A longitudinal section 314 and a transverse section 313 extending horizontally from the bottom of the longitudinal section 314 are included, the upper end of the longitudinal section 314 being the second limit end and the transverse section 313 forming the first limit end. To do. A rotary shaft 500 is fixedly arranged on the limit plate 300 by integral injection molding or another method, and both ends of the rotary shaft 500 are rotatably restricted by the head lower lid 113, and the head 110 is rotated around the rotary shaft 500. Rotate and open and close. One end of the limit shaft 410 is attached to the lateral slide groove 412 of the fixed holder 400 and slides along the lateral slide groove 412, and the other end of the limit shaft 410 extends into the limit hole 310, and the head The limit shaft 410 moves in the limit hole 310 to limit the rotational stroke of the head 110 when the 110 makes a rotary opening / closing motion around the rotary shaft 500.

  In order to achieve the locking of the limit shaft 410 at the first limit end, the fixed holder 400 of the present embodiment is provided with a second elastic lock member, and preferably the second elastic lock member is the second torsion spring 470. The second shift lever 480 is connected between the limit shaft 410 and the fixed holder 400, one end of the second torsion spring 470 is positioned on the fixed holder 400, and the other end is positioned on the existing second shift lever 480. Then, the second shift lever 480 swings reciprocally around the connection point of the fixed holder 400, so that the limit shaft 410 slides reciprocally along the lateral slide groove 412. When the limit shaft 410 moves to the bottom end of the longitudinal section 314 of the limit hole 310, the second torsion spring 470 releases the elastic force, which causes the second shift lever 480 to swing and the second shift lever 480 to move the limit shaft 410. Translating into the transverse section 313, the limit shaft 410 cannot move up and down in the transverse section 313, so that the head 110 correspondingly moves to the first work, as in the situation shown in FIGS. Locked in position.

  In order to realize the unlocking at the first limit end of the limit shaft 410, the fixed holder 400 is provided with a second unlocking member controlled by an electric component, and the second unlocking member is provided by the second shift lever 480. Unlocking is realized by driving the limit shaft 410 so as to reversely translate. Specifically, the electric component is the stepping motor 600 mounted on the fixed holder 400, and the second unlocking member is the stepping motor 600. When it is necessary to unlock the head 110, the stepping motor 600 drives the second dial 490 to rotate, and the second dial 490 moves to the second shift lever. The second shift lever 480 drives the limit shaft 410 so that the limit shaft 410 is swung. 14 and 15 after reverse translation into the directional section 314 to unlock the vertical motion of the limit shaft 410 and to unlock the limit shaft 410 after the rotation limit device is further provided with a drive member. As in the state shown, the drive member provides power to flip the head 110 upwards to the second working position.

  In the present embodiment, for the arrangement method of the drive member and the unlock control of the rotation limit device thereof, it is sufficient to refer to the method described in the first embodiment, and no explanation is given here.

Embodiment 3
16 to 20, FIGS. 16 to 20 show a third embodiment of the present invention. In the present embodiment, the steam heating cooker is a steam rice cooker including a main body and a pan body 220, and the main body includes a body 100, a head 110 protruding from both upper and lower ends on one side of the body 100, and a pedestal 120. It is placed in an open space surrounded by the pedestal 120 and the head 110 so that the pot body 220 can be taken out, and the inside of the body 100 has a steam generator and a steam pipe line for transporting steam. The steam generated from the apparatus is conveyed from the steam line to the head 110, the head 110 has a butt section 160, the exhaust port of the steam transfer line is provided in the butt section 160, and the butt section 160 and the pan 220 are connected. The high temperature steam is transferred to the cooking chamber of the pan body 220 by sealing and abutting the exhaust port of the steam pipe and the intake port of the pan body 220 by the butting.

  In the present embodiment, a boiler-type steam generator is adopted for the steam generator, and the body 100 is provided with a water tank for supplying water to the steam generator. Of course, in some other schemes, the steam generator may be supplied with water by introducing an external water source into the steam generator through a water pipe.

  The lid 210 is provided with an intake port in the pan body 220 so that the intake port and the exhaust port in the abutting portion 160 can be easily matched with each other.

  Specifically, the head 110 has one through hole 174, the abutting portion 160 is provided in the through hole 174, and when the abutting portion 160 moves up and down, the head 110 moves up and down along the axial direction of the through hole 174. The through hole 174 has a function of guiding and limiting the position of the abutting portion 160 when the abutting portion 160 is moved up and down, and prevents the abutting portion 160 from being displaced or tilted during the ascending and descending process. When the butt section 160 rises, the butt section 160 and the pan body 220 are separated from each other, the pan body 220 is taken out of the main body, and when the butt section 160 descends, the butt section 160 and the pan body 220 are butted. The steam in the steam pipeline is smoothly introduced into the cooking chamber of the pan 220 to butt the exhaust port of the butt section 160 and the intake port of the lid 210 in a sealed manner, and heats the food.

  In the present embodiment, the abutting portion 160 moves up by a method called mechanical transmission, separates from the pot body 220, and moves down by a method called manual pressing, and abuts the pot body 220. Compared with a method of driving the abutting portion 160 to move up and down by a motor, the configuration is simpler, the number of parts in the head 110 is smaller, and the manufacturing cost is lower.

  Specifically, in the head 110, a first return spring 171 having one end acting on the abutting portion 160 and the other end acting on the head 110 is provided. When the butt section 160 descends, the first return spring 171 is compressed by the downward pressure of the butt section 160, that is, when the butt section 160 and the pan body 220 butt, the first return spring 171. Is in a compressed state. The head 110 is further provided with an engaging connection portion, and the butting portion 160 has a buckle 170 arranged so as to correspond to the engaging connecting portion, and the butting portion 160 is in a butting state with the pan body 220. In this case, the engagement connection portion and the buckle 170 are engaged and connected to each other, and a position limitation is formed with respect to the upward movement of the butting portion, and the butting portion 160 and the pan body 220 are held in a butted state.

  Preferably, referring to FIG. 5, a plurality of first return springs 171 may be provided, and the plurality of first return springs 171 are evenly distributed so as to be surrounded in the circumferential direction of the abutting portion 160, and such an arrangement is provided. Is received by the first return spring 171 when the abutting portion 160 moves up and down, and the force receiving force is evenly distributed, and the abutting portion 160 inclines due to the non-uniform force receiving force in the process of moving. Never.

  In some other schemes, the number of the first return spring 171 may be one, and one return spring may be fitted on the abutting portion 160, similarly, the abutting portion 160 may move upward. Ensure that it is not tilted and misaligned.

  Further, the head 110 is provided with a control portion for controlling the engagement connecting portion to be disengaged from the buckle 170 in the butting portion 160, so that the butting portion 160 is lifted by the action of the elasticity of the first return spring 171. Then, the pan 220 is separated. The control unit includes a control button 172 that transmits and connects with the engagement connection unit, and the user presses the control button 172 to drive the engagement connection unit to be disengaged from the buckle 170 in the abutting unit 160.

  Preferably, the advantage that the control button 172 is provided at the tip of the head 110 and the control button 172 is provided at the tip of the head 110 is as follows: when the user uses the steam cooker, The control button 172 is directed toward the user, and the user directly discovers and operates the control button 172 according to the operation habits of the user, so that the user experience is excellent.

  A second return spring 173 is provided between the control button 172 and the engagement connection portion, and after the hand is removed from the control button 172, the control button 172 automatically returns by the elastic action of the second return spring 173.

  In the present embodiment, the engagement connecting portion includes engagement arms 176 protruding from both sides of the abutting portion 160, and projects along the direction of the abutting portion 160 to one side of the engaging arm 176 close to the abutting portion 160. Corresponding to the buckle 170 in the abutting portion 160. When the control button 172 is pressed, the forward movement of the engaging arm 176 is perpendicular to the movement direction of the abutting portion 160, and after the engaging arm 176 moves forward, the protrusion on the engaging arm 176 and the abutting portion The buckle 170 in 160 is displaced, and thus the abutting portion 160 moves up by the action of the elastic force of the first return spring 171, and the abutment portion 160 and the pan 220 are separated. A third return spring 177 is provided between the engagement connection portion and the cavity wall of the cavity of the head 110, and the expansion and contraction direction of the third return spring 177 is the same as the movement direction of the engagement connection arm. When the arm moves forward due to the propulsion of the control button 172, the sling is in a state of being stretched and pulled by the engagement connection arm, and when the control button 172 returns, the engagement connection arm moves toward the third return spring 177. It returns by the action of tensile force. In this way, when the user manually pushes the abutting portion 160 to lower the abutting portion so as to abut the pan body 220, the buckle 170 in the abutting portion 160 also engages with the protrusion in the engaging connection arm. Then, the butting portion 160 and the pot body 220 are held together.

  In the present embodiment, when the butt portion 160 and the pan body 220 are separated, the upper end of the butt portion 160 projects to the upper surface of the head 110, and the portion of the butt portion 160 that projects to the upper surface of the head 110 is a manual drive unit. And the user presses the manual drive portion of the abutting portion 160 protruding above the head 110 to complete the abutting of the abutting portion 160 and the pan 220. The manual driving unit is arranged to project on the upper surface of the head 110, which makes the operation more convenient when the user presses the abutting unit 160, and at the same time, the visual effect of the manual driving unit is more remarkable, so that it can be used. Person's experience of use is excellent. When the abutting portion 160 and the pan 220 are abutted, the upper surface of the abutting portion 160 is aligned with the upper surface of the head 110, and thus, in the cooking process, the upper surface of the entire head 110 is a flat surface as a whole. As a result, when the operation display panel 175 is located on the upper surface of the head 110, the user can more clearly and intuitively observe the cooking status of the steam rice cooker.

  Furthermore, in the present embodiment, the abutting portion 160 is further provided with a detection configuration for detecting whether or not the abutting of the abutting portion 160 and the pan body 220 is sufficient. As long as the match is sufficient, the cooking program is normally started, the steam generator operates normally, and thus, when the match between the butt section 160 and the pan body 220 is insufficient, the steam generator is It is prevented from malfunctioning and hot steam being discharged from the exhaust port in the abutting part 160 to cause a burn to the user.

  Specifically, in the present embodiment, a micro switch (not shown) is used to detect whether or not the abutting portion 160 and the pan 220 are sufficiently abutted, and the abutting portion 160 and the pot 220 are sufficiently abutted. , The pan 220 touches the micro switch, and the micro switch sends a signal to the main control panel in the steam rice cooker to unlock the steam generator.

Embodiment 4
Referring to FIG. 21, FIG. 21 shows a fourth embodiment of the present invention.

  In the present embodiment, when the butt portion 160 and the pan body 220 are separated, the upper surface of the butt portion 160 is aligned with the upper surface of the head 110, and when the user prepares for cooking, the pan body 220 is inside the open space of the main body. After that, the butting portion 160 is pressed, the butting portion 160 moves downward, and sinks into the through hole 174 of the head 110 to complete the butting with the pan body 220. According to this method, when the steam rice cooker is in a non-cooked state, the height of the upper surface of the abutting portion 160 and the height of the upper surface of the head 110 match, which is higher than that of the first embodiment. The overall height of the cooker is lower, and at the same time, when the steam cooker is in an idle state, the upper surface of the entire head 110 is flat and the shaping is aesthetic. The rest of the configuration of the present embodiment is the same as that of the third embodiment, so it is not described here.

Embodiment 5
22 to 26, FIGS. 22 to 26 show a fifth embodiment of the present invention.

  As shown in FIGS. 22 to 26, in the present embodiment, a lid is provided with a steam conduit 230, and specifically, the lid 210 is covered by the pot body 220 to form a cooking chamber, and the lid is provided. Is provided with a steam injection hole, and when the head is brought into contact with the pan, steam is introduced into the cooking chamber from the steam injection hole, and a steam conduit 230 is provided in the steam injection hole.

  Preferably, the steam conduit 230 of the present embodiment has a connection part 231 at one end that is close to the lid 210 and an exhaust part 232 that is one end away from the cover 210, and the exhaust part 232 is provided with an exhaust port 233. The pipe diameter of the exhaust part 232 is smaller than the pipe diameter of the connection part 231.

  When cooking, the pan 220 is placed on the main body, the lid 210 of the pan 220 is covered by the pan 220 to form a cooking chamber, and the steam generator 150 in the main body operates to generate steam, The steam reaches the lid 210 through the steam pipe, enters the steam conduit 230 through the steam injection hole 31 in the lid 210, and finally introduces the steam into the cooking chamber from the steam conduit 230, and the food in the cooking chamber To heat. In this embodiment, the steam conduit 230 is preferably made from a food grade stainless steel material. Since the steam conduit 230 is inserted into the food in the cooking chamber, if food grade stainless steel material is adopted, there is no food safety problem, while stainless steel has excellent heat resistance, corrosion resistance and good composition. Has strength and longer life.

  Specifically, during the cooking process, the steam conduit 230 enters below the liquid level in the cooking chamber. As an example of cooking rice, when steam is discharged from the steam conduit 230, high-temperature bubbles are formed, and the high-temperature bubbles float on rice milk. Transferred to rice milk, the rice milk receives heat and boils. Further, in the floating process, the entire rice milk forms a tumbling action due to the bubbles, and the rice milk separated from the steam conduit 230 also receives the heat by contacting the high temperature bubbles due to the flow.

  Preferably, at least a part of the exhaust ports 233 is located under the minimum scale in the pan body 220, and the foodstuffs placed in the pan body 220 may have the minimum scale in the pan body 220 during the actual use. Since it exceeds, a part of the steam is introduced below the liquid level of the food in the pan 220, and it is ensured that the introduced steam stirs and tumbles the food in the pan 220 to allow sufficient heat absorption. Realize effective heating.

  The process in which the steam is discharged from the steam conduit 230 is, in effect, that the air pressure in the steam conduit 230 propels the steam at the exhaust port 233, and the steam at the exhaust port 233 overcomes the liquid pressure of rice milk. Get into the milk. Therefore, the air pressure in the steam conduit 230 determines the distance at which the bubbles escape from the exhaust port 233, and the higher the air pressure in the steam conduit 230, the more the bubbles start to float after reaching a position farther from the steam conduit 230. It should be pointed out here that the distance at which the bubbles escape from the exhaust port 233 refers to the moving distance of the bubbles in the exhaust direction of the exhaust port 233, that is, the distance from the bubbles to the vapor conduit 230.

  In the present embodiment, as the diameter of the steam conduit 230 is much smaller than the inner diameter of the entire cooking chamber and the distance that the bubbles escape from the exhaust port 233 is longer, the movement trajectory of the bubbles becomes larger, and the bubbles propel the rice milk. The range of movement of rice milk becomes wider, the amount of rice milk formed to flow is increased, the tumbling effect of rice milk is improved, and the rice milk at each part in the cooking chamber will eventually Also flows, comes into contact with air bubbles and receives heat, the heat of rice milk in the cooking chamber becomes more uniform, the cooking time is shorter, and the texture of cooked rice is better.

  When the pressure in the steam conduit 230 is small and the steam escapes from the exhaust port 233, it forms bubbles and floats, and only the rice milk near the steam conduit 230 flows and receives heat, and the rice milk away from the steam conduit 230. The heat received by the rice is small, which significantly increases the cooking time, and the heat received by the rice milk in the cooking chamber is uneven, and the texture of cooked rice is not ideal.

  In the present embodiment, the steam conduit 230 has a connection part 231 at one end that is close to the lid 210 and an exhaust part 232 that is one end away from the lid 210, and the pipe diameter of the exhaust part 232 is smaller than the pipe diameter of the connection part 231. The exhaust port 233 is provided in the exhaust unit 232. The steam enters the steam conduit 230 from the steam injection hole 31 in the lid 210, first enters the connecting portion 231, then passes through the exhaust portion 232, and is discharged from the steam conduit 230 through the exhaust port 233 in the exhaust portion 232. Since the pipe diameter of the exhaust part 232 is smaller than the pipe diameter of the connection part 231, when steam enters the exhaust part 232 from the connection part 231, the flow velocity of the steam increases and the steam pressure in the exhaust part 232 increases. In this way, after the steam escapes from the exhaust port 233, it is subjected to a large pressure by the rear steam, so that the steam is discharged so as to be injected, and the steam is released from the steam conduit 230 to a region far from the steam conduit 230. After that, it starts to float, which improves the tumbling effect of the rice milk, makes the heat of the rice milk more uniform, shortens the cooking time of the rice, and improves the texture of the cooked rice.

  Furthermore, in the present embodiment, the steam generated by the steam generator 150 is injected into the pan cooking chamber through the exhaust port 233 of the steam conduit 230, and the equivalent length of steam sprayed through the exhaust port 233 and the radius of the pan body. The ratio is 1/2 to 1. Since the ratio of the equivalent length of steam injection from the exhaust port 233 and the radius of the pan body 220 is 1/2 to 1, after steam is ejected from the exhaust port, the ingredients in the pan body are stirred to be tumbled. Also, ensure that the surrounding area inside the pan is agitated and that heat is evenly received. When the ratio is less than 1/2, it is difficult to stir the peripheral region of the pot body, which causes nonuniform heat reception, and the heating effect is poor. Especially when the main body is used as a platform for steam heating and the pans with different volume sizes are switched, it causes different heating effects, so using the technical solution of the present invention, pans with different sizes can be used. Ensure that each has a good cooking effect. Regarding specific implementation method, when switching between different pans, the control interface has the selection of the appropriate volume size, and after selecting the appropriate volume size, the program will automatically match. The heating effect is secured by ejecting steam with different speeds. Of course, the main body is provided with a detection device for detecting the pot body to be placed, and by matching a suitable cooking program according to the detection result, steam with different speeds is ejected to match. In the present invention, the radius of the pot body 220 refers to the maximum radius in the cross-sectional areas of different heights of the pot body.

  In order to make the flow of steam from the connection part 231 to the exhaust part 232 smoother, in the present embodiment, a transition part 234 is provided between the connection part 231 and the exhaust part 232, and a pipe of the transition part 234 is provided. The diameter gradually decreases from the connecting portion 231 to the exhaust portion 232. Due to the presence of the transition portion 234, the entire vapor conduit 230 has a generally cone-shaped dropper shape, that is, the pipe wall between the connecting portion 231 and the exhaust portion 232 is a sloping wall, and the vapor is connecting portion 231. There is no great flow resistance when flowing from the exhaust pipe 232 to the exhaust part 232, and the fluency of the flow is guaranteed, and the exhaust effect of the steam conduit 230 is excellent.

  Further, when the lid 210 is covered with the pan 220, the steam conduit 230 is located in the central region of the cooking chamber of the pan 220. When the steam conduit 230 is in the central region of the cooking chamber of the pan 220, the steam spreads from the center of the cooking chamber and heats up, the rice milk in the cooking chamber receives heat more evenly, and there is a blind spot of heating. Not not.

  In the present embodiment, the bottom of the exhaust part 232 of the steam conduit 230 is closed, and the exhaust port 233 is provided on the side wall of the exhaust part 232. The steam conduit 230 is inserted into the rice milk when the lid 210 is covered by the pan 220, and in the process of inserting the steam conduit 230 into the rice milk, the steam conduit 230 receives the resistance of the rice milk and receives the force. Is mainly the bottom portion of the steam guide portion, that is, the bottom portion of the exhaust portion 232.

  In the present embodiment, the bottom of the steam conduit 230 is closed and the exhaust port 233 is provided on the side wall of the exhaust part 232 to effectively prevent rice grains in rice milk from entering the steam conduit 230. The rice grain in the rice milk is prevented from being scratched by the exhaust port 233.

  Further, the exhaust port 233 of the exhaust unit 232 is located 1 to 3 cm or less from the liquid surface of the cooking chamber. If the distance of the exhaust port 233 of the exhaust unit 232 located below the liquid surface is less than 1 cm, the speed of introduction of the vapor is too fast, and the ejected vapor impacts the liquid surface, causing the liquid in the exhaust port 233 to be discharged. The steam that has spread to the surroundings and cannot be sufficiently contacted with the liquid exhausted from the exhaust port 233, the cooking time is delayed, and the distance of the exhaust port 233 of the steam conduit 230 located below the liquid level is less than 3 cm. When it is large, the steam forms a large amount of foam on the liquid surface, the foam rises from below the liquid surface to above the liquid surface and explodes, and a large amount of food to be cooked on the inner wall above the liquid surface of the pan 220. Is stuck and affects the user's experience.

  Further, when the hole diameter of the exhaust port 233 is set to 1 mm to 3 mm, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, and when the hole size of the exhaust port 233 is smaller than 1 mm, the exhaust gas in the exhaust port 233 is exhausted. When the pressure is too large and the noise generated by the exhaust port 233 is large and the hole size of the exhaust port 233 is larger than 3 mm, the hole size of the exhaust port 233 is too large and the rice grains in the rice milk are inside the steam conduit 230. It may get inside, it may be difficult to wash, and rice grains in rice milk may be scratched by the exhaust port 233, which affects normal exhaust of the exhaust port 233.

  In the present embodiment, the steam enters the steam conduit 230 from the steam input port and then flows in along the radial direction of the steam conduit 230. Since the bottom of the steam conduit 230 is closed and the exhaust port 233 is located at the side of the exhaust part 232, the inflowing steam is blocked inside the bottom wall of the exhaust part 232. By the action, the last is pushed out from the exhaust port 233. Obviously, since the bottom wall of the exhaust part 232 has a certain reduction effect on the impact force of the steam, the intensity of the steam injected from the exhaust port 233 has a certain attenuation.

  Preferably, in the present embodiment, a guide structure 235 is provided between the inside of the bottom wall of the exhaust part 232 and the inside of the side wall of the exhaust part 232, and the guide structure 235 forms the inside of the bottom wall of the exhaust part 232. It may be a connecting arc surface between the inside of the side wall of the exhaust part 232 or a connecting slope between the inside of the bottom wall of the exhaust part 232 and the inside of the side wall of the exhaust part 232. When blocked by the bottom wall of 232, the guide arrangement 235 has a guiding effect on the rotating and recirculating steam, and the rotating and recirculating steam is introduced into the exhaust port 233 and discharged. In this way, the rotating and recirculating steam is prevented from being further attenuated by causing the secondary direction change.

  Further, the number of exhaust ports 233 is plural, and the plural exhaust ports 233 are arranged so as to be surrounded along the circumferential direction of the exhaust unit 232. In this way, when steam is ejected from the exhaust port 233, rice milk that has an annular ejection shape and is in each direction in the cooking chamber is moved by the bubbles and forms the effect of tumbling. Has excellent tumbling effect and makes the heat of rice milk even.

  After the steam is injected from the exhaust port 233, the air pressure of itself is higher than the liquid pressure of rice milk, so there is a process of bubble expansion, and the bubbles expand and become large, and the space occupied by the bubbles becomes large. The bubbles ejected from the nozzle 233 collide with each other in a small space, canceling out the elasticity of some of the jets, and the bubbles cannot reach the area far from the exhaust port 233. It is disadvantageous for heating.

  In the present embodiment, the adjacent exhaust ports 233 are arranged to be displaced in the direction of the pipe diameter of the steam conduit 230, and the displacement is arranged so that the height positions of the adjacent exhaust ports 233 do not match, and It means that the adjacent exhaust ports 233 do not overlap or do not completely overlap in the radial direction of the steam conduit 230. In this way, the bubbles generated by the adjacent exhaust ports 233 are jetted so as to be shifted vertically, and the collision between the bubbles is reduced, while the exhaust port 233 is provided with a larger area for the exhaust gas. By arranging more exhaust ports 233 in the portion 232 conveniently, and by injecting steam from the exhaust ports 233 that shift vertically, steam is propelled to flow rice milk from two directions, up and down, so that rice milk alternates. The effect of convection is formed, the tumbling of rice milk is more sufficient, and the heat reception of rice milk is more uniform.

  When the exhaust ports 233 are arranged so as to be vertically displaced, after the steam enters the steam conduit 230, it first flows to the exhaust port 233 above the steam conduit 230, and then takes the initiative to partially remove it from the upper exhaust port 233. Of the steam, and the remaining steam, which is not in time to discharge, subsequently flows and is discharged from the steam conduit 230 via the exhaust port 233 below the steam conduit 230. Clearly, the pressure of the steam discharged from the exhaust port 233 located above the steam conduit 230 is large, the injection effect is excellent, and the steam discharged from the exhaust port 233 located below the steam conduit 230 is The pressure effect received is small and the injection effect has a constant damping. As described above, the jet strength of the steam discharged from the exhaust ports 233 located at different upper and lower positions is inconsistent, and the effect of convection of rice milk cannot be formed, or the effect of the formed alternating convection is formed. It affects the tumbling effect and heat receiving effect of rice milk.

  In the present embodiment, at least a part of the projections of the exhaust ports 233, which are arranged in the exhaust unit 232 so as to be vertically displaced, in the circumferential direction of the exhaust unit 232 overlap. In this way, while the arrangement area of the exhaust port 233 in the exhaust part 232 is enlarged, the height difference of the exhaust port 233 which is vertically shifted is small, so that the injection intensity of the steam injected from the lower exhaust port 233 is attenuated. The small, even staggered steam injected from the exhaust port 233 ensures that the rice milk propels it to create the effect of alternating convection.

  In the present embodiment, when cooking, the steam conduit 230 is inserted into the rice milk, and the process of inserting the steam conduit 230 into the rice milk is made smoother, and at the same time, after the rice is cooked, the lid 210 is cooked. After the steam conduit 230 is opened and the steam conduit 230 is removed from the rice, the steam conduit 230 of the present embodiment has an avoidance structure between the bottom wall and the side wall of the exhaust part 232 in order to reduce the influence on the flatness of the rice. An avoidance arrangement 236 is provided to displace solid foodstuffs when cooking solid foodstuffs such as meat and bones while avoidance arrangements 236 reduce the resistance of steam conduit 230 to be inserted into rice milk. To open the passageway for insertion of the steam conduit 230 into the cooking chamber.

  In some embodiments, the avoidance arrangement 236 can be an arcuate transition between the bottom wall and sidewall of the exhaust section 232, and an arcuate transition provided between the bottom wall and sidewall of the exhaust section 232. When the bottom part of the steam conduit 230 has a substantially spherical shape and the spherical bottom part contacts the solid foodstuff, the steam conduit 230 pushes the foodstuff by receiving the component force of moving the foodstuff to the side. , Is inserted into the cooking chamber, thus ensuring that the steam conduit 230 is smoothly inserted into the cooking chamber and that the lid 210 is smoothly covered by the pan body 220, which is convenient for the user.

  In some other embodiments, the avoidance feature 236 may be a direct slope transition between the bottom wall and sidewall of the exhaust section 232, with a direct slope transition between the bottom wall and sidewall of the exhaust section 232. When the steam conduit 230 is inserted into the rice milk by providing the portion 234, the rice milk is divided along the slope transition portion 234, and the slope transition portion 234 functions to divide the liquid surface so that the steam conduit 230 is cooked. The resistance received by the process of being inserted into the chamber is smaller.

  Also, the placement of the avoidance arrangement 236 allows the steam conduit 230 to be inserted into or removed from the rice while the overall outer contour curve of the steam conduit 230 is softer and smoother and the profile is more aesthetic. At that time, the process becomes smoother and the influence on the flatness of the rice is small.

  In the present embodiment, the steam conduit 230 is sealed and fixed to the lid 210 via the connection portion 231, and the connection method is a detachable connection, for example, a detent connection or an engagement connection, which is convenient for the user. The conduit 230 is removed and cleaned.

  Further, when the cooking is completed, before the lid is opened, the operation of the steam generator is stopped, and after the operation of the steam generator 150 is stopped, the conveyance of the high temperature steam to the steam pipeline is stopped. However, the heat insulation of the steam pipeline cannot be objectively guaranteed to be perfect, and the heat of the high temperature steam in the steam pipeline is gradually lost. In this way, the high temperature steam in the steam pipeline is gradually condensed, reducing the air pressure in the steam pipeline, and when the air pressure in the steam pipeline is smaller than the atmospheric pressure in the cooking chamber, the pressure difference between the inside and outside of the steam pipeline is reduced. The juice or the like in the cooking chamber is extruded into the steam line, that is, the phenomenon of reverse suction of the steam line is formed, which makes cleaning the user inconvenient.

  In order to solve the above problem, the present embodiment has a reverse suction prevention hole 237 in the steam conduit 230, and the reverse suction prevention hole 237 is provided above the liquid level of the cooking chamber and communicates with the steam pipeline. Therefore, when the operation of the steam generator 150 is stopped and the inside of the steam pipeline is in a negative pressure state, the gas in the upper part of the cooking chamber enters the steam pipeline in preference to the liquid at the bottom of the cooking chamber. Thus, the pressure difference between the inside and the outside of the steam pipeline is balanced, and the liquid in the cooking chamber is prevented from being sucked back into the steam pipeline.
