Background

The existing cooking appliances in the market, such as rice cookers, basically have the function of cooking porridge, and porridge is sticky, so that overflow easily occurs in the cooking process, and the schemes of the existing cooking appliances for treating overflow can be roughly divided into two types. A more conventional overflow prevention method is that in the cooking process, the heating power is reduced after the liquid is boiled by big fire, and the boiling is changed into slow boiling by small fire, so that the micro boiling in the pot is kept. Another anti-overflow method is to install a foam breaking component (such as an air pump, a fan, etc.) in the cooking utensil, the big fire is used for boiling the liquid and then is changed into the medium fire for quick boiling, the medium boiling is kept in the cooker, but the air bubbles caused by the medium boiling can be eliminated by using the foam breaking component in an auxiliary way.

However, the first overflow prevention scheme is that the pot is in a micro-boiling state, so that the cooking time is longer, and about 1 hour and 30 minutes are required to achieve the ideal viscous effect of porridge. The auxiliary foam breaking component is added in the second scheme, the medium boiling state can be achieved in the pot, the cooking time is greatly shortened, and the quick porridge can be achieved for about 45 minutes, but a large amount of cost is increased.

In addition, the rice cooker is generally provided with a steamer, and the steamer is erected in the cooking cavity and is positioned above the liquid in the cooker in the cooking process, so that some rice cookers have a certain overflow-preventing function by additionally arranging filtering structures such as filtering membranes on the steamer. But locate the filtration of food steamer and mostly use as the consumptive material, increased user's use cost on the one hand, on the other hand before the culinary art at every turn the user need frequently change filtration, in case forget to install filtration, the food steamer then loses anti-overflow function, so uses comparatively inconveniently, user experience is not good enough.

As shown in fig. 1 to 7, an overflow-preventing cooking appliance comprises a pot body 1 with a cooking cavity 11, and an overflow-preventing cage 2 arranged in the cooking cavity 11, wherein the overflow-preventing cage 2 divides the cooking cavity 11 into an upper cavity 112 and a lower cavity 111, the overflow-preventing cage 2 is provided with a through-flow opening 22 communicated with the upper cavity 112 and the lower cavity 111, the overflow-preventing cage 2 is further provided with a backflow opening 21 lower than the through-flow opening 22, the backflow opening 21 is provided with a movable piece 4, and the movable piece 4 can move relative to the overflow-preventing cage 2 to open or seal the backflow opening 21.

The spill cage 2 according to the utility model is provided with a movable element 4 at the return opening 21, the movable element 4 being movable relative to the spill cage 2 to bring the return opening 21 into an open state as well as into a closed state. During cooking, the liquid is located in the lower cavity 111, the heating power is increased to boil the liquid and generate a large amount of steam, and meanwhile, the air pressure in the lower cavity 111 is also increased to generate an air pressure difference between the lower cavity 111 and the upper cavity 112, so that the movable piece 4 moves to seal the backflow port 21 under the pushing of air flow, steam and air pressure. At this time, the upper cavity 112 and the lower cavity 111 are only communicated through the overflow port 22, and the soup boiling in the lower cavity 111 enters the overflow preventing cage 2 through the overflow port 22 and is collected in the overflow preventing cage 2. Because the spill cage 2 has a depth and a lower temperature, the liquid entering the upper chamber 112 will not continue to gush upward, thereby reducing the risk of spillage. When the cooking power is reduced or the cooking is finished, the air pressure difference between the upper cavity 112 and the lower cavity 111 is reduced, and the steam amount in the lower cavity 111 is also reduced, so that the pushing force to the movable part 4 is also reduced, the movable part 4 moves to open the return opening 21, and the liquid stored in the overflow preventing cage 2 can flow back into the lower cavity 111 through the return opening 21, so that no long-time water accumulation exists in the overflow preventing cage 2, and the taste of food in the overflow preventing cage 2 is ensured.

Preferably, the return opening 21 is disposed on the bottom wall of the overflow preventing cage 2, and the overflow opening 22 is disposed on the side wall of the overflow preventing cage 2, and of course, the return opening 21 and the overflow opening 22 may be located on the bottom wall or the side wall of the overflow preventing cage 2 together, and only the return opening 21 is lower than the overflow opening 22.

Moreover, the anti-overflow cage 2 can be used for normal steaming food, and can be used for boiling porridge and stewing meat in the lower cavity 111, and simultaneously steaming steamed bread, steamed stuffed bun, steamed dishes and the like in the upper cavity 112 in the anti-overflow cage 2, so that the multifunctional food is realized, an additional anti-overflow component is not required to be arranged in the cooking appliance, the structure of the cooking appliance is simplified, and the cost is saved.

The utility model is not limited to the control manner of the movement of the movable member 4, and in a preferred embodiment, the movable member 4 can automatically move upwards to seal the return opening 21 under the pushing of air pressure, air flow, steam and the like in the lower cavity 111, and can also automatically move downwards to open the return opening 21 under the action of self gravity. In another embodiment, the movable element 4 can also be associated with a cooking program of the cooking appliance by an electronic control program, so as to move it under program control.

It should be noted that the movement mode of the movable member 4 is not limited in the present utility model, and may be one of the following embodiments:

An embodiment is as follows: in this embodiment, as shown in fig. 1, 3, 4, 5 and 6, the movable member 4 has a connection portion 41, and the connection portion 41 is rotatably connected to the spill-proof cage 2, so that the movable member 4 can rotate around the connection portion to open or close the backflow port 21.

The turnover movement mode of the movable piece 4 has simple structure and flexible movement, can quickly respond and move when being pushed by the airflow in the lower cavity 111, and has higher reliability.

Further, as shown in fig. 6, the movable member 4 further includes a weight portion 43 located at one end of the connecting portion 41, and a blocking portion 42 located at the other end of the connecting portion 41, the blocking portion 42 being located below the return port 21 for blocking the return port 21, and the weight of the weight portion 43 being greater than the weight of the blocking portion 42.

Specifically, as shown in fig. 6, the connecting portion 41 is rotatably connected to one side of the backflow port 21, a projection of the blocking portion 42 toward the anti-overflow cage 2 is located at the backflow port 21, and a projection of the counterweight portion 43 toward the anti-overflow cage 2 is located outside the backflow port 21, so that the backflow port 21 is blocked by the blocking portion 42.

The connecting portion 41 of the movable member 4 is rotatably connected with the overflow preventing cage 2, and the weight of the weight portion 43 is heavier than that of the blocking portion 42, so that the weight portion 43 swings downward under the action of gravity more easily, and the blocking portion 42 swings upward accordingly to block the backflow port 21. In this way, the cooking appliance is ensured to be in a high-power heating stage, the movable piece 4 can be easily pushed to turn over without too large steam quantity and positive pressure in the lower cavity 111, so that the blocking part 42 swings upwards to block the backflow port 21, and the liquid in the lower cavity 111 is prevented from directly rushing into the anti-overflow cage 2 from the backflow port 21 upwards, thereby causing overflow.

Specifically, as shown in fig. 6, since the weight of the weight portion 43 is relatively large, the moment arm of the weight portion 43 is reduced, and the moment arm of the blocking portion 42 is increased, so that in a state in which the movable member 4 is not acted by the pushing force, the blocking portion 42 can swing downward under the action of self gravity, so that the backflow port 21 is in an open state, the liquid in the anti-overflow cage 2 is convenient to flow out, and only when the blocking portion 42 is pushed upward, the blocking portion 42 can be turned upward to block the backflow port 21.

As shown in fig. 6, the movable member 4 is of a sheet structure as a whole, but the manner of increasing the weight of the weight portion 43 is not limited in this embodiment, and the weight may be increased by increasing the thickness of the weight portion 43 to be larger than the thickness of the blocking portion 42, or by fixing a weight to the weight portion 43, or by increasing the weight of the weight portion 43, and is not limited in this embodiment.

Preferably, as shown in fig. 4, 5 and 6, the overflow preventing cage 2 is provided with a limiting rib 26 extending obliquely downwards at the position of the backflow port 21, one side of the limiting rib 26 facing the upper cavity 112 is provided with a diversion slope, and the connecting portion 41 is connected to the lower end of the limiting rib 26, so that the limiting rib 26 can be matched with the movable member 4 in a stop manner to limit the rotation angle of the movable member 4.

It will be appreciated that if the movable member 4 is turned to a vertical state, the direction of the upward gushing of the air flow is consistent, and the air pressure and the thrust of the air flow to the movable member 4 are both upward, so that it is difficult to push the movable member 4 to perform the turning motion, and the movable member 4 cannot seal the backflow port 21.

In this embodiment, the inclined limiting rib 26 may limit the overturning angle of the movable member 4, when one end of the movable member 4 is turned downward to open the backflow port 21, the other end swings upward and gradually approaches the limiting rib 26 and finally stops with the limiting rib 26, at this time, the whole movable member 4 is in an inclined state and cannot rotate to a vertical state, so that the lower end surface of the movable member 4 can contact with the whole air flow in the lower cavity 111, the contact area of the air flow and the movable member 4 is increased, and an upward component and a lateral component are formed after the contact due to the inclination of the lower end surface, so that the movable member 4 is promoted to overturn to seal the backflow port 21. The reliability of the movement of the movable member 4 is improved and the movable member is more easily pushed to turn over. On the other hand, the guiding inclined plane of the limiting rib 26 can also play a role in guiding the liquid in the overflow preventing cage 2, so as to guide the liquid in the overflow preventing cage 2 to flow back downwards along the limiting rib 26 from the backflow port 21.

Embodiment two: in this embodiment, the movable member 4 is floatingly connected to the spill-proof cage 2, so that the movable member 4 can float upwards under the pushing of the air flow in the lower cavity 111 to seal the backflow port 21.

In this embodiment, the movable member 4 may move up and down relative to the overflow preventing cage 2, that is, may float upward to seal the return port 21 when being pushed by the air pressure and the steam in the lower cavity 111, and may fall back down under the action of its own gravity to open the return port 21.

Specifically, in one embodiment, the overflow preventing cage 2 is provided with a through hole at the periphery of the return opening 21, and the movable member 4 is provided with a guide rod passing through the through hole, so that the guide rod can move up and down in the through hole. Further, a stop rib is arranged at the top end of the guide rod and used for stopping the overflow preventing cage 2, limiting the falling amount of the movable piece 4 and preventing the movable piece 4 from falling off from the overflow preventing cage 2.

As a preferred embodiment of the present utility model, as shown in fig. 7, the return opening 21 is disposed in a central area of the bottom wall of the spill-proof cage 2, and the height of the bottom wall of the spill-proof cage 2 gradually decreases from the edge to the position of the return opening 21, so as to form a diversion transition surface 25 on the side of the bottom wall of the spill-proof cage 2 facing the upper cavity 112.

Because the bottom wall of the anti-overflow cage 2 is of an inclined structure, liquid boiling into the anti-overflow cage 2 can gather towards the reflux port 21 under the guiding action of the diversion transition surface 25, so that when the movable piece 4 opens the reflux port 21, the liquid can quickly flow back from the reflux port 21 to the lower cavity 111, and when a user places food into the anti-overflow cage 2, the food is placed at a position far away from the reflux port 21, and the phenomenon that the liquid accumulates at the food for a long time to influence the taste of the food can be avoided. In addition, when more liquid is collected at the reflux port 21, the movable part 4 is pressed to move under the action of gravity of the liquid, so that the reflux port 21 is opened, and the liquid in the overflow preventing cage 2 can be conveniently discharged in time when more liquid is collected.

The diversion transition surface 25 may be an inclined surface, an arc surface, or the like, and is not limited herein.

In a preferred embodiment, as shown in fig. 2, the spill-proof cage 2 is provided with a trigger member 24, the spill-proof cooking appliance is provided with a sensing member 31, and the trigger member 24 triggers the sensing member 31 in a state that the spill-proof cage 2 is placed in the cooking cavity 11.

When a user places the overflow preventing cage 2 in the cooking cavity 11, the trigger piece 24 on the overflow preventing cage 2 triggers the induction piece 31 of the cooking appliance, so that whether the overflow preventing cage 2 is placed or not is detected, on one hand, the preparation work before the user cooks can be prompted, the possibility that the user forgets to place the overflow preventing cage 2 is reduced, and on the other hand, the trigger state of the induction piece 31 can be associated with the cooking mode of the cooking appliance, so that the heating power of the cooking appliance can be adjusted in real time according to the placement state of the overflow preventing cage 2, and the overflow preventing effect is ensured.

It should be noted that the present utility model is not limited to the types and triggering modes of the sensing element 31 and the triggering element 24, and includes, but is not limited to, the following embodiments:

Embodiment one: in the present embodiment, the triggering element 24 triggers the sensing element 31 by contact. For example, in one embodiment, the sensing element 31 is a micro switch, and the triggering element 24 is a triggering protrusion protruding from the spill-proof cage 2, and the triggering protrusion contacts with a contact of the micro switch to form a trigger when the spill-proof cage 2 is placed in the cooking cavity 11.

Embodiment two: in this embodiment, the triggering member 24 can trigger with the sensing member 31 in a non-contact manner, so that the matching of the triggering member and the sensing member 31 is simpler, and the sensing member 31 senses the triggering member 24 more sensitively.

Specifically, in one embodiment, the triggering member 24 and the sensing member 31 are triggered by magnetic induction, for example, the sensing member 31 is a hall element, the triggering member 24 is a magnetic member, and when the spill-proof cage 2 is placed in the cooking cavity 11, the magnetic member enters the sensing range of the hall element to trigger the hall element.

In another embodiment, the sensing element 31 may also be a photoelectric switch, so as to implement non-contact sensing on the triggering element 24, which is not limited herein.

Specifically, as shown in fig. 2, the spill-proof cage 2 is lapped on the edge of the cooking cavity 11 through the flanging 23, so that the spill-proof cage 2 is located at a higher position of the cooking cavity 11, the spill-proof cage 2 is prevented from being immersed when more soup is contained in the lower cavity 111, the sensing piece 31 is arranged on the pot cover 3, and when the pot cover 3 covers the cooking cavity 11, the distance between the sensing piece 31 and the triggering piece 24 is relatively short, so that the triggering piece 24 is easier to trigger the sensing piece 31, and the detection sensitivity and accuracy are improved.

Preferably, the overflow preventing cooking appliance has a first cooking mode and a second cooking mode, and the sensing member 31 is electrically connected to a control unit of the overflow preventing cooking appliance to switch the overflow preventing cooking appliance between the first cooking mode and the second cooking mode.

In one embodiment, the first cooking mode is a high-power heating mode, the second cooking mode is a low-power heating mode, the cooking program logic of the cooking appliance is shown in fig. 8, when the sensing element 31 is not triggered by the triggering element 24, the spill-proof cage 2 is indicated not to be placed in the cooking cavity 11, at this time, the spill-proof performance of the cooking appliance is poor, and the cooking appliance heats the food in the second cooking mode with low power, and stews the food with low fire, so that the risk of the soup popping is reduced. When the sensing element 31 is triggered by the triggering element 24, it indicates that the overflow preventing cage 2 is placed in the cooking cavity 11, and the cooking appliance has better overflow preventing performance, the control unit receives the signal of the sensing element 31, so that the heating power of the cooking appliance is increased, the heating efficiency is improved, the cooking time is shortened, and meanwhile, soup cannot overflow.

Preferably, the sensing member 31 detects the presence or absence of the trigger member 24 at intervals, and the control unit adjusts the cooking mode of the cooking appliance in real time, so that the cooking appliance can switch the cooking mode in time and intelligently even if the user puts in or takes away the spill-proof cage 2 at random during cooking. For example, the spill-proof cage 2 is not placed at the beginning of cooking, the cooking time is timed to be 1 hour and 30 minutes, the remaining time displayed by the display screen after half an hour is 1 hour (2/3 of the time remains), the cooking appliance heats the food with low power, and the cooking process is in the second stage of the whole. At this time, the user puts the overflow preventing cage 2 into the cooking cavity 11, the trigger member 24 triggers the sensing member 31, the control unit automatically switches the cooking process to the second stage of the high-power cooking process of the instant porridge, the remaining time displayed on the display screen is reduced to 2/3 of the instant porridge time (total time is 45 minutes and is reduced to 30 minutes), and vice versa.

By arranging two sets of cooking logics on the cooking appliance, the situation that a user forgets to put the overflow preventing cage 2 causes the overflow can be prevented, and the mode logic is intelligently switched, so that the situation that the porridge cooking effect is poor or the overflow caused by putting or taking the overflow preventing cage 2 in the middle of the user can be prevented.

It should be noted that the installation position of the overflow port 22 is not limited in the present utility model, and in one embodiment, the overflow port 22 is disposed at the bottom wall of the overflow preventing cage 2. In a preferred embodiment, the overflow 22 is provided in the side wall of the cage 2, as shown in fig. 7.

Specifically, as shown in fig. 7, the flow-through ports 22 are multiple groups, and each group of flow-through ports 22 is uniformly spaced along the circumferential direction of the spill-proof cage 2 on the side wall of the spill-proof cage 2. The more uniform the overflow port 22 covers the side wall of the overflow preventing cage 2, the better the uniformity of the cooked porridge, because the overflow port 22 bears the pressure release hole of the lower cavity 111 at the same time, and the liquid in the cooking cavity 11 can be accumulated below the position of the overflow port 22 along with the pressure release airflow.
