[ detailed description ] of the utility model

The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present utility model.

The appearances of the phrases such as "exemplary," "some embodiments," and the like in the following text are meant to be "serving as examples, embodiments, or illustrative," and any embodiment described as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, it will be appreciated by those skilled in the art that the present disclosure may be practiced without some of these specific details.

Referring to fig. 1 to 3, the embodiment of the utility model discloses a cooking appliance with an anti-overflow function, comprising an appliance body 100, a cover body 110 and a cooking cavity 120 formed by the two, wherein the cover body 110 comprises an inner cover 130 and an upper cover, an exhaust assembly 200 is arranged on the upper cover, the exhaust assembly 200 forms an exhaust cavity 210 communicated with the cooking cavity 120, an air inlet 220 is arranged at the lower end of the exhaust assembly 200, an air outlet 221 is arranged at the upper end of the exhaust assembly 200, a steam inlet 140 communicated with the cooking cavity 120 is arranged on the inner cover 130, and the exhaust assembly 200 stretches into the steam inlet 140 to enable the air inlet 220 to be connected with the steam inlet 140, and the air outlet 221 is communicated with the outside.

A heating device is further disposed in the cooking apparatus for heating the cooking cavity 120 to cook food in the cooking cavity 120, during cooking, steam in the cooking cavity 120 can leave the cooking cavity 120 through the steam inlet 140 and enter the exhaust cavity 210 through the air inlet 220, and the steam diffuses in the exhaust cavity 210 and finally is discharged to the outside through the air outlet 221.

If the cooking cavity 120 is filled with food materials such as rice, sweet potato, and pork leg containing a large amount of starch and colloid components, bubbles which are not easy to break are formed on the upper layer of the cooking liquid during the cooking process, and the bubbles are attached to the lower surface of the inner cover 130 during the boiling process of the cooking liquid, and leave the cooking cavity 120 together with steam through the steam inlet 140 and enter the exhaust cavity 210. In order to prevent bubbles from overflowing out of the cover 110, the cooking appliance is further provided with a cooling device 300, the cooling device 300 can generate cooling gas for breaking bubbles, the temperature inside the bubbles is high, and after the bubbles contact low-temperature air, the bubbles are rapidly broken due to rapid surface temperature reduction, so that the bubbles cannot be discharged to the outside.

In order to avoid that the cooling gas may affect the cooking effect, the cooling device 300 is communicated with the exhaust chamber 210 through the air inlet channel 310, so that the cooling gas generated by the cooling device 300 is introduced into the exhaust chamber 210 through the air inlet channel 310 to eliminate bubbles in the exhaust chamber 210. By such design, the cooling gas generated by the cooling device 300 is not directly introduced into the cooking cavity 120, so that the influence on the cooking temperature in the cooking cavity 120 is reduced, and the influence on the temperature measuring component for measuring the temperature of the cooking cavity 120 is also reduced. In addition, since bubbles must pass through the exhaust assembly 200 during the process of overflowing to the outside, bubbles having a risk of overflowing are concentrated in the exhaust chamber 210, and cooling gas is also concentrated in the exhaust chamber 210, and the bubbles in the exhaust chamber 210 can be sufficiently contacted with the cooling gas to be rapidly ruptured, so that the cooking appliance has a better anti-overflow performance. Because the cooking utensil has better anti-overflow performance, can suitably increase the culinary art firepower, shorten the culinary art time.

In the prior art, the cooling gas is fed into the cooking cavity to contact the upper layer of the cooking liquid to prevent the bubbles from overflowing to the outside by removing the bubbles on the surface of the cooking liquid, but in order to achieve the above object, it is necessary to ensure that the cooling gas can contact the cooking liquid in a large area. In the present utility model, since only the bubbles located in the exhaust chamber 210 need to be purged and the bubbles are concentrated in the exhaust chamber 210 having a much smaller volume than the cooking chamber 120, the cooling device 300 can purge the bubbles at a lower gas flow rate.

Referring to fig. 2 and 3, based on the above-described embodiment, in one embodiment of the present utility model, in order to further reduce the influence of the cooling gas on the cooking, the intake passage 310 guides the cooling gas to the intake port 220 in a manner offset from the axis of the intake port 220. In fig. 3, the score line indicated by Q is the axis of the air intake.

Since the flow direction of the cooling gas after leaving the air inlet passage 310 is deviated from the axis of the air inlet 220, the cooling gas does not directly enter the air inlet 220 but directly enter the cooking cavity 120, so that at least part of the cooling gas can collide with the inner wall of the air outlet cavity 210 around the air inlet 220, thereby reducing the influence on cooking.

The air inlet channel 310 can guide the flow direction of the cooling air to blow a large amount of cooling air to the air inlet 220, so that the space temperature around the air inlet 220 is lower than other parts in the air outlet cavity 210, and the air bubbles can contact with the low-temperature air in a short time when entering the air outlet cavity 210 to quickly break and form cooking liquid, and flow back into the cooking cavity 120 along the air inlet 220, thereby reducing the diffusion of the air bubbles in the cooking cavity 120, and avoiding the possibility that the air bubbles are not cleared in time and diffuse in the air outlet cavity 210 to overflow out of the cover 110.

Referring to fig. 2 and 3, in one embodiment of the present utility model, one side edge of the air inlet 220 extends into the exhaust chamber 210 to form a first guide 230, the first guide 230 guides steam to one end of the air inlet passage 310 communicating with the exhaust chamber 210, and the first guide 230 has a guiding and blocking effect on the cooling gas and the bubbles. As shown in fig. 3, the direction of the joint in fig. 3 is the diffusion path of the steam in the exhaust chamber.

The bubbles entering the exhaust chamber 210 are blocked by the first guide part 230 and cannot move in a direction away from the intake passage 310, but are broken by being sufficiently contacted with the cooling gas before being diffused as the steam approaches the intake passage 310.

The part of the cooling gas blown to the air inlet 220 from the air inlet passage 310 is blocked by the first guide 230 to be diffused at the position of the air inlet 220, so that the cooling gas can be concentrated at the position of the air inlet 220 to enhance the bubble breaking effect.

The size of the air inlet 220 is smaller than that of the bottom wall of the exhaust cavity 210, the first guiding portion 230 and the bottom wall of the exhaust cavity 210 on the side of the air inlet 220 close to the air inlet channel 310 can form an opening, and the air inlet channel 310 guides the cooling air into the opening, so that the cooling air and the air bubbles are concentrated in a small range, and the foam breaking effect is further improved.

Referring to fig. 2 and 3, in one embodiment of the present utility model, the exhaust chamber 210 has a vent hole 240 through which the intake passage 310 extends into the exhaust chamber 210, and one side edge of the vent hole 240 extends into the exhaust chamber 210 to form a second guide 231 for guiding the cooling gas.

The ventilation hole 240 is provided at the bottom wall of the exhaust chamber 210, and the intake passage 310 blows cooling gas into the exhaust chamber 210 from bottom to top, and the cooling gas flows along the second guide 231 while being in contact with the second guide 231, and is guided by the second guide 231 toward the first guide 230. Because the aperture of the air inlet channel 310 is smaller, the blown cooling air has a higher speed, so that the cooling air is too concentrated to contact a large amount of bubbles, and part of the bubbles are blown away to the periphery and even help to overflow to the outside, and the cooling air is buffered under the action of the second guiding part 231, and meanwhile, the blowing range is enlarged, so that a large amount of bubbles can fully contact the cooling air to break, and the blowing force of the cooling air is insufficient to blow the bubbles to diffuse rapidly, thereby ensuring the overflow preventing performance of the cooking utensil.

Referring to fig. 2 and 3, in one embodiment of the present utility model, the exhaust chamber 210 includes a first buffer chamber 211 and a second buffer chamber 212 communicating with each other, the second buffer chamber 212 is located at a side portion of the first buffer chamber 211, the air inlet passage 310 communicates with the first buffer chamber 211, the exhaust port 221 is provided at a top wall of the second buffer chamber 212, and the air inlet 220 is provided at a bottom wall of the first buffer chamber 211.

In the process of being discharged to the outside through the exhaust assembly 200, the steam passes through the first buffer chamber 211, then enters the second buffer chamber 212, and finally is discharged to the outside through the exhaust port 221. When entering the exhaust cavity 210, the bubbles enter the first buffer cavity 211 and are concentrated in the first buffer cavity 211, so that the area occupied by the bubbles in the exhaust cavity 210 is reduced, and the air inlet channel 310 sends a large amount of cooling gas into the first buffer cavity 211, so that a large amount of cooling gas is diffused in the first buffer cavity 211 to remove concentrated bubbles and prevent the bubbles from diffusing into the second buffer cavity 212. The excessive cooling gas is discharged to the outside after entering the second buffer chamber 212 from the first buffer chamber 211. As shown in fig. 3, the direction of the joint in fig. 3 is the diffusion path of the steam in the exhaust chamber.

The cooking utensil of the utility model is an electric cooker. The baffle 232 is disposed on the back side of the first guide part 230 in the exhaust cavity 210, the baffle 232 divides the exhaust cavity 210 into the first buffer cavity 211 and the second buffer cavity 212, the baffle 232 and the first guide part 230 can block steam, after entering the exhaust cavity 210, most of the steam can diffuse in the first buffer cavity 211 under the blocking, and then enter the second buffer cavity 212 through a gap between the edge of the baffle 232 and the inner wall of the exhaust cavity 210, the baffle 232 can limit the air flow entering the second buffer cavity 212, thereby limiting the flow entering the exhaust cavity 210 from the cooking cavity 120, increasing the pressure in the cooking cavity 120 and helping to improve the cooking effect.

If there is an unbroken bubble diffusing into the second buffer chamber 212, the bubble passes through the gap between the baffle 232 and the inner wall of the exhaust chamber 210, and then enters the large space from the small space, and the shape of the bubble in the process and the pressure in the bubble can support the broken bubble, i.e. the cooking utensil has the function of secondary breaking. In this way, if there are still bubbles entering the second buffer chamber 212, the amount of bubbles will not reach the condition of overflowing to the outside, and will eventually break naturally with the evaporation of water vapor and the temperature change after the cooking is finished.

The first guide part 230 guides the steam and the bubbles in a direction away from the baffle plate 232, so that the steam and the bubbles are firstly diffused in a direction away from the baffle plate 232 after entering the exhaust cavity 210, and a large amount of bubbles are prevented from directly entering the second buffer cavity 212 to overflow to the outside.

Referring to fig. 1 to 3, in one embodiment of the present utility model, the exhaust assembly 200 includes a lower exhaust member 250 and an upper exhaust member 251 mounted on the lower exhaust member 250, the upper cover is provided with a mounting hole 150, the exhaust assembly 200 is mounted on the upper cover through the mounting hole 150, the upper exhaust member 251 is pressed against the lower exhaust member 250 by its own weight to allow the upper exhaust member 251 and the lower exhaust member 250 to be detachable, and when a user removes the upper exhaust member 251 during cleaning, the upper exhaust member 251 and the lower exhaust member 250 are cleaned respectively.

The baffle 232 is disposed on the upper exhaust member 251, and the baffle 232 extends from the top wall of the exhaust chamber 210 toward the bottom wall, so that steam enters the second buffer chamber 212 from between the lower end of the baffle 232 and the bottom wall of the exhaust chamber 210, between the side edge of the baffle 232 and the side wall of the exhaust chamber 210, and the diffusion path of the steam in the process of being discharged to the outside is prolonged, thereby further limiting the flow of the steam and ensuring the cooking pressure in the cooking chamber 120.

If the side edge of the baffle plate is arranged to be propped against the side wall of the exhaust cavity, the steam can be limited to enter the second buffer cavity only from the position between the lower end of the baffle plate and the bottom wall of the exhaust cavity, and the cooking pressure in the cooking cavity can be further ensured.

Referring to fig. 2 and 3, in one embodiment of the present utility model, a through hole 160 is provided in the upper cover corresponding to the steam inlet 140 such that steam can pass from the cooking chamber 120 through the steam inlet 140 and the through hole 160 into the exhaust chamber 210, based on the above embodiment.

In order to facilitate the installation and positioning of the exhaust assembly 200, the lower end of the lower exhaust member 250 is provided with a boss 260, the boss 260 penetrates the through-hole 160 and is inserted into the steam inlet 140, and the air inlet 220 is provided on the boss 260. The inner wall of the through-hole 160 has a radial positioning effect on the boss 260 to define the position of the exhaust assembly 200 on the upper cover, thereby facilitating the installation of the exhaust assembly 200.

Cooking liquid boiling during cooking may also enter the vent assembly 200, but the height to which the cooking liquid boils is limited, and the provision of the boss 260 allows cooking liquid entering the vent assembly 200 to flow back into the cooking chamber 120 without passing up over the boss 260 and into other parts of the vent chamber 210.

The cover 110 is further provided with a sealing member 400, the sealing member 400 extends from the upper cover around the through hole 160 into the cooking cavity 120, and the sealing member 400 can provide sealing between the boss 260 and the through hole 160, between the boss 260 and the steam inlet 140, and between the lower end of the lower exhaust member 250 and the upper cover, so that leakage of steam and bubbles in the process of entering the exhaust cavity 210 can be avoided. Under the action of the sealing member 400, steam and bubbles do not leak to the region between the inner lid 130 and the upper lid except the exhaust assembly 200 to cause pollution, and a user does not need to detach the inner lid 130 each time to clean the upper surface of the inner lid 130 and the lower surface of the upper lid when cleaning the cooking appliance; the steam and bubbles do not leak over the upper cover to affect the normal operation of the electronic components disposed on the upper cover.

By providing the sealing ring 420, the cooling gas leakage can be avoided to reduce the bubble breaking efficiency, and meanwhile, the leakage of the steam and bubbles to the upper cover through the vent holes 240 can be avoided to influence the electronic components arranged on the upper cover, and in addition, the leaked steam and bubbles can pollute the area between the inner cover 130 and the upper cover.

In addition, the sealing ring 420 is pressed between the first channel 320 and the vent hole 240 to deform, so that the first channel 320 and the vent hole 240 can maintain a matching state, and the exhaust assembly 200 is prevented from shaking up and down relative to the cover 110 under the action of steam due to the pressure in the cooking cavity 120 caused by limiting the steam discharge flow.
