Disclosure of Invention

The utility model discloses problem to prior art existence proposes a cooking utensil with unsteady dish that generates heat, and the defect that great heeling appears easily in the dish that generates heat of aim at overcoming current cooking utensil.

The utility model discloses a realize like this:

a cooking utensil with a floating heating plate comprises a pot body and a pot cover covered on the pot body, wherein the pot body comprises a heat-insulating cover and the heating plate which is arranged on the heat-insulating cover in a floating way,

the heating plate is provided with a plurality of positioning columns, and a limiting structure is arranged between the heating plate and the heat-insulating cover to limit the side inclination angle of the heating plate.

When the pressure of the inner container to the heating plate is deviated to one side of the heating plate, the stressed side of the heating plate can move downwards under the action of the pressure, and the opposite side of the heating plate is subjected to smaller force of the heating plate and hardly moves downwards. The atress side that generates heat the dish removes the restraint that can receive limit structure to a certain extent, and limit structure prevents that the atress side that generates heat the dish and further moves downwards, avoids generating heat the dish too slope to avoid the upper end too slope of inner bag, the upper end and the pot cover of the inner bag of being convenient for cooperate.

After the cooker cover is covered, under the pressure action of the cooker cover, the acting force of the inner container on the heating plate tends to be balanced. The locating hole has on the heat preservation covers, and the reference column passes the locating hole, if the dish that generates heat is too inclined for the heat preservation cover, the reference column that generates heat on the dish also can take place great slope, and the reference column is easy to interfere with the hole edge of locating hole, and the hole edge of locating hole can hinder the reference column downstream, can lead to generating heat the dish and can not resume the horizontality from the tilt state to hinder the pot cover to exert an effect to the inner bag, the lid that further increases the pot cover closes the degree of difficulty. Limiting structure can avoid generating heat the dish too slope, reduces the hole edge of reference column and locating hole and takes place the risk of interfering, reduces the pot cover and can not cover the risk of closing on the pot body.

Preferably, the limiting structure comprises a limiting column which is positioned on the heating plate and extends downwards; the heating plate usually comprises a heating tube and a metal plate body, and the limiting column is fixed on the metal plate body. Be convenient for set up spacing post on the metal disk body, spacing post can integrated into one piece in the metal disk body, also can weld on the metal disk body, and the metal disk body is also convenient for process the screw hole, and spacing post also can be through the screw thread can dismantle fixedly to the metal disk body on.

Or the limiting structure comprises a limiting column which is positioned on the heat-insulating cover and extends upwards;

or the limiting structure comprises an elastic limiting part positioned between the heating plate and the heat-insulating cover. One of the main reasons for the side inclination of the heating plate is that food is not uniform in the inner container, a large amount of food can be accumulated on one side of the inner container, the inner container on the side can generate larger pressure on the heating plate, food can be accumulated on which side of the inner container, and uncertainty exists in the accumulation degree, accumulation amount and distance of the food deviating from the center of the inner container. The elastic limiting piece increases along with the deformation quantity of the elastic limiting piece, and the elastic force of the elastic limiting piece also increases along with the deformation quantity of the elastic limiting piece, so that the self-adaptive heating plate can adapt to the change of the eccentric force applied to the self-adaptive heating plate.

Preferably, the connecting line between the limiting structure and the corresponding positioning column passes through the center of the heating plate. If the heating plate is inclined, one position of the heating plate can not move up and down, other positions of the heating plate can deflect by taking the position as a fulcrum or a rotating shaft, and the farther the position is, the larger the deflection amount is. The mid point of fulcrum and pivot is more nearly from the edge of heating plate, and the degree of deflection of heating plate will be bigger, and the reference column compares in the mid point of two reference column lines and is close to the edge of heating plate more, so when deflecting around the fulcrum, the more serious deflection can take place for the heating plate, limit structure is in corresponding the reference column line through the heating plate center, limit structure can exert the restriction effect of deflecting to the condition of deflecting around the fulcrum better like this, avoids the biggest heeling of heating plate to take place.

Preferably, the positioning columns are distributed on the periphery of the heating plate at equal intervals, and the distance from the limiting structure to two adjacent positioning columns is equal. When the heating plate is biased to one side of the heating plate by the pressure of the inner container, the resultant force of the pressure of the inner container on the heating plate is mainly positioned on the outer side of the connecting line of the adjacent positioning columns. Set up the reference column in the periphery of the dish that generates heat, be favorable to increasing the region that adjacent reference column line encloses, reduce the outside region of adjacent reference column line, reduce the dish that generates heat and receive the pressure of inner bag and be partial to the condition emergence of one side of the dish that generates heat. The equal interval distribution's reference column, the regional area in the city enclosed by adjacent reference column line is the biggest, can further reduce the dish risk of heeling that generates heat.

Preferably, the limiting structure is located on a circumscribed circle of a polygon formed by connecting lines of all adjacent positioning columns. When the dish that generates heat takes place to heels, the degree that moves down of the dish edge that generates heat relative with the fulcrum is the biggest, and when the reference column was located the periphery of dish that generates heat, reference column and limit structure set up with the circle can make limit structure be close to the edge of dish that generates heat to the best spacing effect of performance.

Preferably, the limit structure is positioned on the heating plate, and the distance from the limit structure to the edge of the heating plate is less than 10 mm. The limiting structure is as close as possible to the edge of the heating plate so as to exert the limiting effect as good as possible.

Preferably, the number of the limiting structures is the same as that of the positioning columns. Therefore, any positioning column is taken as a fulcrum, and a corresponding limiting structure can play a role in preventing the side inclination.

Preferably, the floating distance of the limiting structure is greater than or equal to the normal floating distance of the positioning column. The normal floating distance refers to the normal downward moving distance of the heating plate after the liner is placed when the heating plate does not incline. The floating distance of the limiting structure is larger than or equal to the normal floating distance of the positioning column, so that the limiting structure can be prevented from influencing the normal floating of the heating plate. If limit structure's the normal floating distance that is less than the reference column apart from, when the dish that generates heat does not take place to heels, the reference column has not moved down in place yet, and limit structure has just restricted the dish that generates heat and has further moved down to make the dish that generates heat can not move down to the anticipated position, can not provide more abdicating for higher inner bag, can reduce the pot body to the suitability of inner bag, can not exert the dish that generates heat and float and set up due effect.

Preferably, the floating distance of the limiting structure is smaller than the maximum floating distance of the positioning column. Thus, the limiting structure can be ensured to play a role. When the dish that generates heat takes place to heels, if limit structure's the floating distance is greater than the biggest floating distance of reference column, the dish that generates heat has heeled to some reference columns and is in the biggest lower limit position easily, and the reference column has can't further move down, and limit structure still does not reach extreme position, and limit structure can not exert its limiting displacement, and the dish that generates heat still can appear great heeling.

Preferably, an elastic part is arranged on the positioning column, the elastic part is located above the heat-insulation cover so that the heating plate tends to move upwards, the lower end of the positioning column penetrates through the heat-insulation cover downwards, and an anti-falling part is arranged at the lower end of the positioning column so as to prevent the positioning column from separating from the heat-insulation cover upwards. When the inner container is taken out of the pot body, the heating plate does not have downward pressure, and the heating plate can move upwards to the upper limit position under the action of the elastic piece.

The utility model provides a cooking utensil with dish that generates heat floats, when the inner bag is partial to the pressure of the dish that generates heat when one side of dish that generates heat, the atress side of the dish that generates heat will move down under the pressure effect, and its opposite side receives the power of the dish that generates heat less, can hardly move down. The atress side that generates heat the dish removes the restraint that can receive limit structure to a certain extent, and limit structure prevents that the atress side that generates heat the dish and further moves downwards, avoids generating heat the dish too slope to avoid the upper end too slope of inner bag, the upper end and the pot cover of the inner bag of being convenient for cooperate.

Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

This embodiment provides a steam rice cooker, is the utility model discloses the innovation scheme is a concrete application on steam rice cooker, the utility model discloses the innovation scheme can also be used in cooking utensil such as pressure cooker.

As shown in fig. 1 to 5, the steam rice cooker comprises a cooker body 400 and a cooker cover 300 covering the cooker body 400, wherein the cooker body 400 comprises a heat-insulating cover 100 and a heating plate 200 floatingly mounted on the heat-insulating cover 100, the heating plate 200 is provided with a plurality of positioning posts 210, and a limiting structure 220 is arranged between the heating plate 200 and the heat-insulating cover 100 to limit the side inclination angle of the heating plate 200.

As shown in fig. 3, when the pressure of the inner container 500 on the hot plate 200 is biased to one side of the hot plate 200, the force-receiving side of the hot plate 200 moves downward under the pressure, and the opposite side thereof is less forced by the hot plate 200 and hardly moves downward. The atress side that generates heat set 200 moves to a certain extent and can receive limit structure 220's restraint, and limit structure 220 prevents that the atress side that generates heat set 200 from further moving downwards, avoids generating heat set 200 too slope to avoid the upper end too slope of inner bag 500, the upper end and the pot cover 300 of the inner bag 500 of being convenient for cooperate.

After the pot cover 300 is covered, the acting force of the inner container 500 on the heating plate 200 tends to be balanced under the pressure of the pot cover 300. Have the locating hole 110 on the heat preservation cover 100, the locating column 210 passes the locating hole 110, if the dish 200 that generates heat is too inclined for the heat preservation cover 100, the locating column 210 on the dish 200 that generates heat also can take place great slope, the locating column 210 is easy to be interfered with the hole edge of locating hole 110, the hole edge of locating hole 110 can hinder the locating column 210 downstream, can lead to the dish 200 that generates heat and can not resume to the horizontality from the tilt state, thereby hinder the effort performance of pot cover 300 to inner bag 500, further increase the lid of pot cover 300 and close the degree of difficulty. The limiting structure 220 can prevent the heating plate 200 from being too inclined, reduce the risk of interference of the hole edges of the positioning column 210 and the positioning hole 110, and reduce the risk that the pot cover 300 cannot cover the pot body 400.

As shown in fig. 1 to 4, the limiting structure 220 includes a limiting pillar extending downward on the heating plate 200. The heating plate 200 generally includes a heating tube and a metal plate body on which a stopper is fixed. Be convenient for set up spacing post on the metal disk body, spacing post can integrated into one piece in the metal disk body, also can weld on the metal disk body, and the metal disk body is also convenient for process the screw hole, and spacing post also can be through the screw thread can dismantle fixedly to the metal disk body on.

As shown in fig. 3, the heating plate 200 tilts with a positioning column 210 as a fulcrum 230, the heating plate 200 tilts until the limiting structure 220 abuts against the heat-insulating cover 100, the limiting structure 220 stops further downward movement to prevent the heating plate 200 from further tilting, and at this time, the tilt angle of the heating plate 200 is small, so that the pot cover 300 can be conveniently covered on the pot body 400, and the positioning column 210 can be conveniently moved further downward.

In other alternative embodiments, the limiting structure 220 may also be a limiting post fixed on the heat-insulating cover 100, that is, the limiting structure 220 includes a limiting post extending upward on the heat-insulating cover 100.

In other alternative embodiments, the limiting structure 220 may also be an elastic limiting member, and specifically, the limiting structure includes an elastic limiting member located between the heat-generating plate 200 and the heat-insulating cover 100, and the elastic limiting member may be a spring. One of the main reasons why the side-tipping of the hot plate 200 occurs is that the food in the inner container 500 is not uniform, the food may be accumulated in a large amount on one side of the inner container 500, the inner container 500 generates a large pressure on the hot plate 200, the food is accumulated on the specific position of the inner container 500, and uncertainty exists in the accumulation degree, accumulation amount and distance of the food from the center of the inner container 500. The elastic limiting member increases its elastic force with the increase of the deformation amount, so that the adaptive heating plate 200 is subjected to the change of the eccentric force. The elastic locating part can also be matched with a limiting column for application, and the limiting column can ensure that the heating plate 200 has a reliable limit inclination angle.

As shown in fig. 4, a connection line between the limiting structure 220 and the corresponding positioning column 210 passes through the center of the heating plate 200. If the heating plate 200 is tilted, one position of the heating plate 200 will not move up and down, and the other positions of the heating plate 200 will deflect with the position as a fulcrum or a rotating shaft, and the farther away from the position, the larger the deflection amount. The closer the midpoint of the fulcrum and the rotating shaft is to the edge of the heating disc 200, the greater the deflection degree of the heating disc 200 is, and the positioning column 210 is closer to the edge of the heating disc 200 than the midpoint of the connecting line of the two positioning columns 210, so when deflecting around the fulcrum, the more serious deflection of the heating disc 200 can occur, the limiting structure 220 passes through the center of the heating disc 200 corresponding to the connecting line of the positioning column 210, and thus the limiting structure 220 can better play a role in limiting deflection for the deflection around the fulcrum, and the tilting of the heating disc 200 to the maximum degree is avoided. In other alternative embodiments, a line connecting the limiting structure 220 and the corresponding positioning column 210 may also be offset from the center of the heat generating tray 200.

As shown in fig. 4, the positioning pillars 210 are distributed at equal intervals around the periphery of the heating plate 200, and the distance from the limiting structure 220 to two adjacent positioning pillars 210 is equal. When the heating plate 200 is biased to one side of the heating plate 200 by the pressure of the inner container 500, the resultant force of the pressure of the inner container 500 on the heating plate 200 is mainly located outside the connection line of the adjacent positioning columns 210. The positioning columns 210 are arranged on the periphery of the heating plate 200, so that the area surrounded by the connecting lines of the adjacent positioning columns 210 is increased, the area outside the connecting lines of the adjacent positioning columns 210 is reduced, and the situation that the heating plate 200 is biased to one side of the heating plate 200 by the pressure of the inner container 500 is reduced. The equal interval distribution's reference column 210, the regional area in the city enclosed of adjacent reference column 210 line is the biggest, can further reduce the risk that generates heat and coil 200 heels.

Further referring to fig. 4, in the embodiment, the number of the positioning columns 210 is three, two adjacent positioning columns 210 are connected to form a triangle, when the resultant force of the pressure of the inner container 500 on the heating plate 200 is located at the periphery of the triangle, the heating plate 200 will tilt, the larger the area of the triangle is, the lower the possibility that the resultant force falls at the periphery of the triangle is, the three positioning columns 210 are distributed at the periphery of the heating plate 200 at equal intervals, so that the area of the triangle is maximized, and the purpose of reducing the tilting risk of the heating plate 200 is achieved.

In other alternative embodiments, the positioning column 210 can also be disposed on the area between the center of the heat generating tray 200 and the periphery of the heat generating tray 200.

As shown in fig. 4, the position-limiting structure 220 is located on the circumscribed circle of the polygon formed by the connecting lines of all the adjacent positioning pillars 210. When the heating tray 200 is tilted, the downward movement of the edge of the heating tray 200 opposite to the pivot is the largest, and when the positioning column 210 is located at the periphery of the heating tray 200, the positioning column 210 and the limiting structure 220 are arranged in the same circle, so that the limiting structure 220 is close to the edge of the heating tray 200, and the best limiting effect is achieved.

In the embodiment where the positioning column 210 is disposed on the area between the center of the heat generating tray 200 and the periphery of the heat generating tray 200, the distance from the limiting structure 220 to the edge of the heat generating tray 200 is less than 10mm, for example, 0mm, 2mm, 5mm, and 9 mm. The spacing structure 220 is as close as possible to the edge of the heating plate 200 so as to exert the spacing effect as good as possible.

As shown in fig. 4, the number of the position-limiting structures 220 is the same as the number of the positioning pillars 210. Therefore, any positioning column 210 is taken as a fulcrum, and a corresponding limiting structure 220 can play a role in preventing the side inclination.

The floating distance of the position-limiting structure 220 is greater than or equal to the normal floating distance of the positioning column 210. The normal floating distance is a normal downward moving distance of the heating plate 200 after the inner container 500 is placed when the heating plate 200 is not tilted. The floating distance of the position limiting structure 220 is greater than or equal to the normal floating distance of the positioning column 210, so that the influence of the position limiting structure 220 on the normal floating of the heating plate 200 can be avoided. If the floating distance of the limiting structure 220 is smaller than the normal floating distance of the positioning column 210, when the heating plate 200 does not tilt, the positioning column 210 does not move down to the right position, and the limiting structure 220 limits the heating plate 200 to move down further, so that the heating plate 200 cannot move down to the expected position, cannot provide more abdications for the higher inner container 500, can reduce the adaptability of the pot body 400 to the inner container 500, and cannot exert the floating effect of the heating plate 200.

The floating distance of the position limiting structure 220 is smaller than the maximum floating distance of the positioning column 210. This ensures that the limiting structure 220 can function. When the heating plate 200 is tilted, if the floating distance of the limiting structure 220 is greater than the maximum floating distance of the positioning column 210, it is easy to happen that the heating plate 200 is tilted to a position where a part of the positioning column 210 is located at the maximum lower limit position, the positioning column 210 cannot move down further, and the limiting structure 220 still does not reach the limit position, so that the limiting structure 220 cannot exert its limiting effect, and the heating plate 200 still tilts greatly.

As shown in fig. 2, the positioning column 210 is provided with an elastic member 211, the elastic member 211 is located above the heat-insulating cover 100 to make the heat-generating plate 200 move upward, the lower end of the positioning column 210 downwardly passes through the heat-insulating cover 100, and the lower end of the positioning column 210 is provided with an anti-falling portion 212 to prevent the positioning column 210 from separating from the heat-insulating cover 100 upward. When the inner container 500 is taken out of the pot body 400, there is no downward pressure on the heating plate 200, and the heating plate 200 is moved upward to the upper limit position by the elastic member 211.
