As shown in fig. 1 to 24, the electric cooker provided in an embodiment of the present application includes an upper cover 110, a steam release box 120, a steam release box seat 130, a monitoring mechanism, a control system, a cooker body 150 and an inner container 160. Wherein the steam box seat 130 is disposed on the upper cover 110, and the steam box 120 is detachably mounted on the steam box seat 130.

Referring to fig. 1 to 8, the steam discharging box 120 includes a steam discharging case 121, a steam discharging pipe 122, a weight 123, a weight member 124, and an operating member 125. The steam release casing 121 is provided with a steam release hole 121a and a steam release channel 121b communicated with the steam release hole 121a and the external environment. The steam exhaust pipe 122 is disposed in the steam exhaust hole 121a of the steam exhaust casing 121 and is in sealing contact with the sidewall of the steam exhaust hole 121a, i.e. when steam is exhausted, steam is exhausted through the steam exhaust pipe 122. The weight 123 is movably disposed outside the steam exhaust pipe 122, i.e. outside the steam exhaust hole 121 a; the weight 123 is movable to switch between a blocking position blocking the exhaust pipe 122 and an exhaust position away from the exhaust pipe 122. In other words, the weight 123 is movably disposed outside the steam vent 121 a; the weight 123 is movable to switch between a blocking position to block the steam release hole 121a and a steam release position away from the steam release hole 121 a. It is understood that the outside of the exhaust pipe 122 refers to the side of the exhaust pipe 122 away from the inner cavity of the liner 160. When the weight 123 is located at the plugging position, it is in sealing connection with the steam exhaust pipe 122, so as to prevent the steam in the inner cavity of the liner 160 from being exhausted through the steam exhaust pipe 122, see fig. 4 and 5. When the weight 123 is located at the steam exhaust position, the weight 123 is far away from the steam exhaust pipe 122, i.e. the steam exhaust pipe 122 is no longer blocked by the weight 123, so that the steam in the inner cavity of the liner 160 can be exhausted freely through the steam exhaust pipe 122, see fig. 6.

Of course, it will be appreciated that in other possible embodiments, there may be no exhaust pipe in the exhaust hole, and the weight is directly in sealing engagement with the side wall of the exhaust hole when in the exhaust position.

Furthermore, it can be understood that the air vent hole 121a is communicated with the inner cavity of the inner container 160, so that when the air pressure in the inner container 160 is too high, the air pressure in the inner container 160 can be reduced by the air vent hole 121a and the air vent channel 121b.

The weight 124 is provided on the gas release case 121. The weight 124 is movable to switch between a weighted position, a free position, and a raised position. Weight 123 is positioned in the blocking position, weight 124 can be switched between the weighted position and the free position. The weight 124 is configured to: when the weight is at the weight position, a weight force directed to the steam discharge hole 121a is applied to the weight 123, so that the inner cavity of the liner 160 has a larger pressure to drive the weight 123 to move to the free position, namely, the inner cavity of the liner 160 can maintain a larger pressure, see fig. 4 and 7; in the free position, the weight force disappears, that is, the inner cavity of the inner container 160 has a smaller pressure relative to the weight position, so that the weight 123 can be driven to move to the free position, that is, the inner cavity of the inner container 160 can maintain a smaller pressure, as shown in fig. 5. The weight 124 is further configured to drive the weight 123 from the blocking position to the exhausting position when the free position is switched to the lifting position, as shown in fig. 6.

It can be understood that, in the present embodiment, the weight 123 also increases the weight force between the weight 123 and the exhaust pipe 122 when receiving the weight force directed to the exhaust hole 121 a. If the embodiment without the exhaust pipe is adopted, the weight is added to the weight force between the weight 123 and the sidewall of the exhaust hole 121a when the weight is applied to the exhaust hole 121 a.

The operating member 125 is movably arranged on the steam release housing 121; the operating member 125 is movable to switch between a high pressure position, a low pressure position and a non-pressure position to drive the weight 124 to switch between a weight position, a free position and a raised position. In other words, when the operating member 125 is in the high pressure position, the weight 124 is in the weight position, see FIG. 4; when the operating member 125 is in the low pressure position, the weight 124 is in the free position, see FIG. 5; when the operating member 125 is in the non-pressure position, the weight 124 is in the raised position, see fig. 6.

The steam release box 120 for the electric cooker can adjust the pressure kept in the electric cooker by switching the counterweight part 124 between the counterweight position and the free position so as to meet the cooking demands of different cooked foods and better ensure the taste, color and form of the foods.

Of course, it is understood that the pressure in the electric cooker is not limited to be regulated only by the steam discharging box 120, but can be regulated by temperature or the like. Specifically, for example, when the temperature in the electric cooker reaches a preset value, heating of the electric cooker is suspended, so that the temperature in the electric cooker is reduced, and the pressure in the electric cooker is properly reduced.

Specifically, referring to fig. 4 and 7, the weight 123 is provided with a bridging portion 123a. When the weight 124 is at the weight position, the weight 124 is configured to overlap the overlapping portion 123a of the weight 123, so that the weight 123 and the steam exhaust pipe 122 are pressed against each other by the gravity of the weight 124, and the pressure in the electric cooker is adjusted.

Specifically, the weight 124 is disposed around the weight 123. The bridging portion 123a is disposed on the outer side of the weight 123, is ring-shaped, and is disposed at the bottom side of the weight 124.

Referring to FIGS. 4 to 6, the weight 123 is provided with a top 123b. The weight member 124 is configured to be abutted against the top member 123b of the weight 123 when the free position is switched to the raised position, so as to drive the weight 123 to move, thereby enabling the weight 123 to be at the steam exhaust position. In the present embodiment, the top 123b and the weight 123 are separate components. The outer wall of the weight 123 is provided with a groove, and the top piece 123b is sleeved and fixed in the groove of the weight 123. Of course, it should be understood that in other possible embodiments, the fixing method of the top piece and the weight is not limited thereto, and any fixing method between the top piece and the weight can be used; in addition, in another possible embodiment, the top piece and the weight can be integrally formed.

Referring to fig. 4 to 7, a weight 124 is movably provided on the steam release housing 121 to switch between a weight position, a free position, and a raised position. Of course, in other possible embodiments, the weight 124 may also be movable by rotation, or a combination of rotation and movement, to switch between the weight position, the free position, and the raised position.

The direction in which the weight 124 moves is the first direction m-m, see fig. 4. The venting box 120 further includes a lift table 126; the lift table 126 is configured to: lifting and lowering along the first direction m-m with the movement of the operating member 125 to drive the weight 124 to move along the first direction m-m.

Specifically, the moving direction of the weight 124 is the depth direction of the inner container 160 of the rice cooker, and is also the vertical state of the rice cooker when it is placed on the horizontal plane. Therefore, when the weight 124 is at the weight position, the self-gravity is converted into the weight force between the weight 123 and the exhaust pipe 122.

Further, referring to fig. 4, when the weight 124 is located at the weight position, there is no contact between the weight 124 and the lifting platform 126, so that the gravity of the weight 124 can be fully converted into the weight of the counter weight 123, and the electric rice cooker has a larger pressure in a high-pressure state without excessively increasing the weight of the steam release box 120. In other words, in case of satisfying the pressure required for the high-pressure state of the electric rice cooker, the weight of the steam discharging box 120 is made smaller, and the weight of the electric rice cooker is also made smaller.

Referring to fig. 9 to 12, the lifting platform 126 is provided with a lifting groove 126a, and an included angle between an extending direction of any position of the lifting groove 126a and the first direction m-m is an acute angle. The venting box 120 further includes an adjustment member 127. The adjusting member 127 is movable with the movement of the operating member 125, and the movement direction is perpendicular to the first direction m-m. The adjusting member 127 has a lifting insertion portion 127a that mates with the lifting groove 126 a. Therefore, the adjusting member 127 can move to drive the lifting plug 127a to move along the lifting slot 126a, thereby driving the lifting platform 126 to lift.

Of course, it is understood that in another possible embodiment, the lifting groove 126a may be provided on the adjusting member 127, the lifting insertion portion 127a may be provided on the lifting platform 126, and the lifting platform 126 may be driven to lift by the movement of the adjusting member 127.

Specifically, the operating member 125 is rotatably provided on the steam release case 121. The adjustment member 127 is rotatable with rotation of the operating member 125. The elevating groove 126a is a spiral groove. More specifically, the adjusting member 127 is fixed relative to the operating member 125, so that rotation of the operating member 125 drives rotation of the adjusting member 127. More specifically, referring to fig. 9 and 13, the adjusting member 127 has a first limiting portion 127b, and the operating member 125 has a second limiting portion 125a that mates with the first limiting portion 127b to limit the relative positions of the adjusting member 127 and the operating member 125. Specifically, the first limiting portion 127b is a limiting post, the second limiting portion 125a is a limiting groove, and the first limiting portion 127b is in interference fit with the second limiting portion 125 a. It will be appreciated that in other embodiments, the manner in which the operating member 125 is secured to the adjustment member 127 is not limited thereto, and may be secured in any other manner.

It will be appreciated that in other embodiments, the movement of the operating member 125 is not limited to rotation, but may be movement, or a combination of movement and rotation. The lifting table 126 can be driven to lift by the movement of the operation member 125.

Referring to fig. 2, 9 and 13, the operating member 125 is provided separately from the adjusting member 127 and fixedly coupled thereto. It will be appreciated that in other possible embodiments, the operating member 125 and the adjustment member 127 may also be integrally formed.

Referring to fig. 14 and 15, the steam release box 120 further includes a sensing structure 190 for sensing movement of the operating member 125 to different positions. Thus, the operator can clearly sense the position of the operation member 125, and avoid deviation of the cooking program of the electric cooker caused by excessive or insufficient operation.

Specifically, the sensing structure 190 includes three sensing limiting grooves 191 disposed on the gas release housing 121, sensing members 192 matching the sensing limiting grooves 191, and second elastic members 193 with two ends respectively abutting against the operating member 125 and the gas release housing 121. The rotation of the operating member 125 can drive the sensing member 192 to rotate, so that when the sensing member 192 is inserted into the sensing limiting groove 191, an operator can obviously sense that the sensing member 192 is inserted into the sensing limiting groove 191. The three sensing limiting grooves 191 respectively correspond to the high-pressure position, the low-pressure position and the non-pressure position of the operating member 125, so that when an operator senses that the sensing member 192 of the operating member 125 is inserted into the corresponding sensing limiting groove 191, the operator stops continuously rotating the operating member 125, thereby enabling the operating member 125 to be more accurately maintained at the desired position.

Referring to fig. 13, the operating member 125 is provided with a third limiting portion 125b. The third limiting portion 125b is configured to limit the position of the second elastic member 193. Specifically, the third limiting portion 125b is a limiting groove, and the second elastic member 193 is partially inserted into the third limiting portion 125b.

Of course, the sensing element 192 may be partially inserted into the third limiting portion 125b, so that the relative position of the sensing element 192 and the operating element 125 in the direction perpendicular to the first direction m-m can be better defined, so that the position of the operating element 125 can be more accurately determined by the sensing element 192.

Referring to fig. 13 and 14, the second elastic member 193 may be a spring. Of course, the second elastic member is not limited to the spring, but may be other elastic members.

Of course, it is understood that the number of the sensing limiting grooves is set corresponding to the number of the position states of the operating member, and is not limited to three.

It will be appreciated that the sensing structure is not limited to the above structure, and the operator can sense that the operating member is moved to different positions.

Optionally, the operating member is provided with an identification pointer, and the gas release shell or the upper cover is provided with an identification matched with the identification pointer and used for identifying the position of the operating member. So as to facilitate the operator to judge the general position of the operating member.

Referring to fig. 3-6 and 8, the steam release box 120 further includes a manual steam release operator 128. The manual steam exhaust operation member 128 is provided on the steam exhaust housing 121. The manual steam exhaust operation member 128 is configured to move relative to the steam exhaust housing 121 under the action of external force to drive the weight 123 to move to the steam exhaust position, as shown in fig. 8. It can be appreciated that when the weight 123 is located at the steam exhaust position, steam in the liner 160 flows out through the steam exhaust channel 121b. Specifically, the direction of the steam flow is referred to as the direction indicated by the arrow in fig. 8. Thus, the steam discharging box 120 has the function of manually discharging steam and the function of adjusting the pressure in the electric cooker.

The venting box 120 also includes a linkage assembly 129. The linkage assembly 129 is configured to: and moves with the manual exhaust operator 128 to move the weight 124 to the raised position. The manual operation member 125 adjusts the position of the weight member 124 through the linkage assembly 129, and further adjusts the weight 123 to the steam release position, thereby realizing manual steam release.

It will be appreciated that in other possible embodiments, the linkage assembly can also drive the weight directly to the steam release position.

Specifically, the manual steam exhaust operator 128 is movably provided on the steam exhaust housing 121. The linkage assembly 129 is a lever assembly. The manual exhaust operator 128 moves to tilt the linkage assembly 129, which in turn moves the weight 124.

More specifically, the moving direction of the manual steam exhaust operator 128 is perpendicular to the top surface of the steam exhaust box 120, so that the manual steam exhaust operator 128 can be operated by pressing. The steam release box 120 is further provided with a reset member 128a for resetting the manual steam release operation member 128. Specifically, the return member 128a is an elastic member with both ends respectively abutting against the steam release casing 121 and the manual steam release operating member 128. When the manual exhaust operator 128 is pressed, the reset element is compressed; after the pressing force acting on the manual steam exhaust operator 128 is canceled, the manual steam exhaust operator 128 is reset by the reset member 128a.

It will be appreciated that in other embodiments, the linkage assembly 129 is not limited to a lever assembly, and may be any structure that enables the weight 124 to be linked to the manual operating member 125. Likewise, the manual exhaust operator 128 may be movable in a manner other than movement, rotational movement, a combination of movement and rotation, or the like. Referring to fig. 2, 3, 15 and 16, the upper cover 110 has a steam release box seat 130; the steam box 120 is detachably mounted on the steam box seat 130. The steam box 120 is detachable, thereby facilitating cleaning of the steam box 120.

Specifically, the side wall of the steam release casing 121 is also provided with a mounting buckle 121d; the upper cover 110 has a venting box seat 130. The steam release box seat 130 is provided with a mounting clamping groove 131 matched with the mounting buckle 121 d. I.e. the steam box 120 is connected with the steam box seat 130 by means of clamping. It should be noted that, the steam-discharging box base 130 has a mounting space 132, and the mounting slot 131 is disposed on a sidewall of the mounting space 132.

More specifically, the mounting buckle 121d includes a clip 121e and a first elastic member 121f disposed between the clip 121e and the air release case 121. When the steam box 120 is mounted on the steam box seat 130, the clamping piece 121e is pressed first, so that the clamping piece 121e overcomes the elastic force of the first elastic piece 121f and contracts inwards, and the steam box 120 can be inserted into the mounting space 132 of the steam box seat 130. When the steam release box 120 is inserted into the installation space 132 of the steam release box seat 130 until the clamping piece 121e corresponds to the installation clamping groove 131, the clamping piece 121e is inserted into the installation clamping groove 131 under the elastic action of the first elastic piece 121f, so that the installation buckle 121d is clamped with the installation clamping groove 131. The first elastic member 121f can also better maintain the state that the clamping member 121e is inserted into the mounting clamping groove 131, thereby maintaining the mounting stability of the steam release box 120.

Referring to fig. 2 and 18 to 22, the rice cooker further includes a locking ring 170 rotatably provided to the upper cover 110. The lock ring 170 is rotatable to switch between the locked and the open states. The locked state of the lock ring 170 is seen in fig. 19 and 20, and the open state of the lock ring 170 is seen in fig. 21 and 22. The lock ring 170 is provided with a push portion 171 inside. The mounting groove 131 penetrates through the side wall of the steam discharging box seat 130. The top 121g is provided on the steam release casing 121. The top 121g is located on the side of the mounting card slot 131 that is remote from the steam box 120. In other words, the top 121g and the steam box 120 are respectively located at two sides of the sidewall of the steam box seat 130. The locking ring 170 is configured such that when rotated from the locking state to the opening state, the pushing portion 171 pushes the top 121g to extend into the mounting clip groove 131, so as to eject the mounting clip 121d out of the mounting clip groove 131, thereby removing the steam release case 120 from the steam release case seat 130, and accomplishing the removal of the steam release case 120.

It will be appreciated that the lock ring 170 is in the locked condition and the venting cartridge 120 cannot be removed. Only when the locking ring 170 is in the open state, the venting cartridge 120 may be removed. Thus, by rotating the locking ring 170 to the locked state, the steam release case 120 can be prevented from being erroneously detached.

It will be appreciated that fig. 2, 16-22 illustrate only one manner of mounting the venting box 120. It will be appreciated that in other embodiments, the manner of mounting the venting cartridge is not limited thereto, and removal of the venting cartridge may be accomplished.

The electric cooker further comprises a monitoring mechanism and a control system. The monitoring mechanism is used to monitor the status of the operating member 125. The control system is used for receiving the monitoring result of the monitoring mechanism and controlling the cooking program of the electric cooker according to the monitoring result.

Specifically, referring to fig. 23 and 24, the monitoring mechanism includes a magnetic member 141 provided on the adjusting member 127, and three sensors provided on the steam release case 121 and matched with the magnetic member 141, the three sensors being a first sensor 142, a second sensor 143, and a third sensor 144, respectively. The first sensor 142, the second sensor 143, and the third sensor 144 correspond to the high-pressure position, the low-pressure position, and the no-pressure position of the operation member 125, respectively. When the operating member 125 is in the high-pressure position, the magnetic member 141 is located within the monitoring range of the first sensor 142; when the operating member 125 is in the low pressure position, the magnetic member 141 is located within the monitoring range of the second sensor 143; when the operating member 125 is in the non-pressure position, the magnetic member 141 is located within the monitoring range of the third sensor 144.

In particular, the magnetic member may be a magnet. Of course, in another possible embodiment, the magnetic member may be an electromagnet, or a magnetic structure formed by mixing a magnetic material and a non-magnetic material, etc. may be a structure that can be monitored by the sensor.

It is to be understood that the number of sensors is not limited to three, and may correspond to the number of position states of the operating element.

Of course, it is understood that embodiments of the monitoring mechanism are not limited thereto. For example, in another possible embodiment, a distance sensor is provided to select an appropriate position on the gas discharge casing, and the position of the operating element is determined by monitoring the position of the magnetic element; for another example, a trigger piece is arranged on the adjusting piece, three contact switches are arranged on the steam release shell, and the three contact switches are respectively arranged corresponding to the high-voltage position, the low-voltage position and the non-voltage position of the operating piece. Thus, when one of the trigger switches is triggered by the trigger member, the trigger switch is triggered.

Further, optionally, the electric cooker further comprises a display panel.

The control method of the electric cooker comprises the following steps:

s01, monitoring the state of the operation piece 125, and controlling a display panel to display a menu of a corresponding state according to a monitoring result;

s02, selecting a matched cooking program according to the menu selected by the user.

The control method has fewer steps, can quickly determine the final cooking program, and ensures that the control system is simpler to set.

Of course, the control method of the electric cooker is not limited thereto. For example, in one possible embodiment, the control method of the electric cooker includes:

s01, monitoring the state of the operation piece 125;

s02, controlling a display panel to display a menu for a user to select, and judging whether the menu is matched with a monitoring result of the monitoring mechanism according to the menu selected by the user;

s03, when the menu selected by the user is not matched with the monitoring result of the monitoring mechanism, controlling the display panel to display the state of the matched operation piece 125;

s04, after the menu selected by the user is matched with the monitoring result of the monitoring mechanism, selecting a matched cooking program.

According to the control method, a user does not need to know the pressure requirement of each dish, and the operation piece is operated according to the prompt of the display panel after the menu is selected.

For another example, in another possible implementation manner, the control method of the electric cooker includes:

s01, monitoring the state of the operation piece 125;

s02, controlling a display panel to display a menu for a user to select, and selecting a matched cooking program according to the menu selected by the user;

s03, judging whether the monitoring result of the monitoring mechanism is matched with the monitoring result of the monitoring mechanism according to a menu selected by a user;

and S04, when the menu selected by the user is not matched with the monitoring result of the monitoring mechanism, controlling the display panel to display the state of the matched operating piece 125.

It will be appreciated that most cooking programs initially have a heating step. The time taken for the user to operate the operation member 125 to the correct state according to the prompts of the display panel is generally much less than the time of the initial heating step of the cooking program. Therefore, by the control method, the electric cooker can enter a cooking program first, and the total cooking time is saved.

It will be appreciated that in other embodiments the weight may be switched between the weight position and the free position only. Similarly, when the weight is in the weight position, a weight force directed to the steam vent is applied to the weight. When the weight is in the free position, the weight force is lost. Correspondingly, the operating member is also movable to switch between a high pressure position and a low pressure position to drive the weight member to switch between the weight position and the free position. Of course, the weight can also move and be kept at the exhaust position under the action of other structures, so that the electric cooker is kept in a pressureless state.

It should be understood that the above examples are illustrative and are not intended to encompass all possible implementations encompassed by the claims. Various modifications and changes may be made in the above embodiments without departing from the scope of the disclosure. Likewise, the individual features of the above embodiments can also be combined arbitrarily to form further embodiments of the utility model which may not be explicitly described. Therefore, the above examples merely represent several embodiments of the present utility model and do not limit the scope of protection of the patent of the present utility model.
