Description

Technical Field

[0001] The invention belongs to the technical field of cooking boxes, in particular to an electric pressure cooking box. Background Art

[0002] The electric steamer is a high-tech kitchen appliance that uses a heating plate (evaporation plate) to convert water into high-temperature steam to cook food 100% with steam. It has a powerful pure steaming function. It can quickly steam dishes, steam rice, steam soup, and heat meals, and has the functions of precise temperature control, locking in nutrition, reducing fat and salt, and maintaining the original flavor and freshness of food.

[0003] The electric steamer heats and cooks food by injecting water from a water tank into the heating plate inside the steamer, which is done entirely through heat transfer.

[0004] When steaming food, first put the food into a container, then put the food into a steaming box, then add water into the water tank, close the door, and then start the steaming box. After the steaming box is started, the heating plate can evaporate water to generate steam, and the steam will gradually fill the steaming chamber, and then the steam will heat the food in the steaming box, thereby heating the food;

[0005] However, since the space of the cooking chamber in the cooking box is fixed, when a single food ingredient needs to be heated, the generated steam will also fill the cooking chamber, resulting in a decrease in the utilization rate of the steam. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0051] The slide plate 3 is provided with multiple rows of first through holes 31; the air cavity 2 is provided with multiple rows of air inlets 24 on the side facing the slideway 23; the air outlet groove 22 is provided with multiple air outlets 25 on the side close to the slideway 23, and a pressure relief valve is provided in the air outlet 25, and the pressure relief valve is used to relieve the pressure of the cooking chamber 11 to prevent the pressure in the cooking chamber 11 from being too high;

[0052] The upper and lower slide plates 3 are located on opposite sides and are both provided with a driving assembly in the box body 1, and the other end of the driving assembly is connected to the slide plate 3; under the action of the driving assembly, the top of the slide plate 3 fits with the top of the slideway 23 in the initial state, and there is a gap between the bottom of the slide plate 3 and the bottom of the slideway 23, and the first through holes 31 on the slide plates 3 on both sides are respectively misaligned with the air inlet 24 and the exhaust port;

[0053] The two opposing slide plates 3 are both fixedly connected with a support plate 4, and the support plate 4 is in contact with the inner wall of the cooking chamber 11, and the bottom row of through holes on the slide plate 3 is located below the support plate 4;

[0054] A steaming component is provided between the two support plates 4, and the steaming component is used to steam food;

[0055] In this embodiment, the cooking assembly includes a cooking plate 41; the cooking plate 41 is provided with evenly arranged air holes; and the two side end surfaces of the cooking plate 41 close to the support plate 4 are both fixedly connected with long plates 42;

[0056] A groove 43 is formed on one end surface of the two support plates 4 close to the long plate 42, and the long plate 42 on the cooking plate 41 slides in the groove 43;

[0057] The upper and lower end surfaces of the cooking plate 41 are respectively provided with two convex grooves 44 located at the front and rear sides of the air hole; the upper and lower end surfaces of the two support plates 4 are also provided with convex grooves 44, and the convex grooves 44 on the support plates 4 are connected with the convex grooves 44 on the cooking plate 41;

[0058] Convex blocks 45 are slidably connected in two convex grooves 44 respectively provided on the upper and lower end surfaces of the two support plates 4;

[0059] The upper and lower sides of the two support plates 4 are respectively provided with an upper plate 46 and a lower plate 47; the bottom of the upper plate 46 is fixedly connected to the convex block 45 in the convex groove 44 above the support plate 4, and fits with the upper surface of the support plate 4; the top of the lower plate 47 is fixedly connected to the convex block 45 in the convex groove 44 below the support plate 4, and fits with the lower surface of the support plate 4;

[0060] The two upper plates 46 and the lower plate 47 are both provided with uniformly arranged second through holes 48; a telescopic tube 49 is inserted into each of the second through holes 48, and the other end of the telescopic tube 49 is inserted into the first through hole 31 provided on the slide plate 3;

[0061] The two opposite lower plates 47 are both fixedly connected with U-shaped bins 471, and one of the U-shaped bins 471 slides inside the other U-shaped bin 471 and is staggered.

[0062] A U-shaped groove 461 is formed on the top of the upper plate 46; a top plate 462 is slidably connected in the U-shaped groove 461, and a spring is fixedly connected to the bottom of the top plate 462, and the other end of the spring is fixedly connected to the bottom of the U-shaped groove 461; the top of the top plate 462 is in contact with the bottom surface of the U-shaped bin 471 on the upper cooking assembly;

[0063] Specifically, before steaming a single food, first place the food container on the cooking plate 41 on the cooking mechanism below, then push the upper plate 46 and the lower plate 47 on both sides of the food to move toward the food position. When the upper plate 46 and the lower plate 47 move toward the food side, the upper plate 46 and the lower plate 47 will drive the convex block 45 to move in the convex groove 44, and at the same time, the bottom end surface of the upper plate 46 will move along the upper surface of the cooking plate 41, and the top plate 462 on the upper plate 46 will move along the bottom end surface of the U-shaped bin 471 at the bottom of the upper cooking mechanism, and at the same time, the lower plate 47 will move along the bottom end surface of the cooking plate 41, and at the same time, the two U-shaped bins 471 will be driven to overlap and approach each other, and the upper plate 46 and the lower plate 47 will move together. The upper plate 46 and the lower plate 47 will gradually stretch the telescopic tube 49. When the upper plate 46 and the lower plate 47 move to both sides of the food, they stop moving further, and then control the driving assembly installed in the lower slide 23 to work. The driving assembly will drive the slide plate 3 in the lower slide 23 to move downward, and the downwardly moving slide plate 3 will drive the support plate 4, the cooking plate 41, the upper plate 46 and the lower plate 47 to move downward. In the process of the upper plate 46 moving downward, the top plate 462 will move upward under the push of the spring, so that the top plate 462 can always fit with the U-shaped bin 471 at the bottom of the upper cooking mechanism. At the same time, the downwardly moving slide plate 3 will drive the multiple rows of first through holes 31 to overlap with the air inlet 24 and the exhaust port, and then the food can be steamed.

[0064] More specifically, when the box door 13 is closed, the sealing layer 14 on the box door 13 will fit with the cooking plate 41, the upper plate 46, the lower plate 47 and the partition 16, so that the cooking plate 41, the upper plate 46, the lower plate 47 and the upper U-shaped bin 471 can form a closed space, and at the same time, the space below the partition 16 can form a closed space, and then the water in the water tank 15 will flow into the heating plate 12. When the water contacts the heating plate 12, water vapor will be generated, and the generated water vapor will flow into the air cavity 2 through the air channel 21. Since the first through hole 31 on the lower slide plate 3 coincides with the air inlet 24 at this time, the steam in the air cavity 2 will enter the first through hole 31 through the air inlet 24, and then the steam will flow along the telescopic tube 49. The steam in the telescopic tube 49 above the cooking plate 41 will flow between the two upper plates 46, and the steam in the telescopic tube 49 below the cooking plate 41 will flow into the two opposite U-shaped bins 471. The steam in the U-shaped bin 471 can pass through the cooking plate 41 to heat the food from below, and the steam flowing out of the upper plate 46 can heat the side of the food, and the generated liquid will flow into the U-shaped bin 471. When the pressure in the box body 1 is too high, the control system automatically controls the pressure relief valve to open, and part of the steam between the upper plates 46 on both sides will enter the telescopic tube 49 of the left upper plate 46, and then flow into the first through hole 31 of the left slide plate 3 through the telescopic tube 49, and then the steam will pass through the air outlet 25 into the air outlet groove 22 and be discharged. By forming a closed space with the cooking plate 41, the upper plate 46, the lower plate 47 and the upper U-shaped bin 471, and passing the steam into the space, the steam can heat the food in the space, thereby avoiding the need for the steam to completely fill the cooking chamber 11 before starting to heat the food, thereby improving the utilization rate of the steam and accelerating the heating efficiency of the food.

[0065] Furthermore, when two kinds of food need to be heated, the two kinds of food can be placed on the two steaming plates 41 respectively, and then the driving components in the upper and lower slides are controlled to work, thereby driving the slide plate 3 in the upper and lower slideways 23 to move downward, and making the first through hole 31 on the slide plate 3 coincide with the adjacent air inlet 24 and air outlet 25, and then closing the door 13. When the door 13 is closed, two closed spaces will be formed in the two steaming mechanisms, and then steam will flow into the two spaces, so that the food in the two spaces can be heated. Since the formed spaces are closed, the problem of cross-flavoring of different foods when heated can be avoided.

[0066] Embodiment 2

[0067] The driving component is a first electric telescopic rod 32;

[0068] Specifically, since the driving component is the first electric telescopic rod 32, when the slide plate 3 needs to be controlled to move upward, the first electric telescopic rod 32 can be directly controlled to drive the slide plate 3 to move, so that the slide plate 3 can move in the slideway 23;

[0069] More specifically, when it is necessary to heat multiple foods of the same type at one time, the foods are placed on the steaming plates 41 on the two steaming mechanisms, and then the door 13 is closed. The steam generated by evaporating water from the heating plate 12 will enter the air cavity 2. When the steam fills the air cavity 2, the first electric telescopic rods 32 in the upper and lower slides 23 are simultaneously controlled to drive the slide plate 3 to move downward. During this process, the first through holes 31 on the upper and lower slide plates 3 can be overlapped with the adjacent air inlets 24 at the same time, so that the steam can enter the enclosed spaces in the two steaming mechanisms at the same time, thereby heating the ingredients on the two steaming mechanisms at the same time, and relatively reducing the temperature difference between the two steaming mechanisms to avoid the temperature in the lower steaming mechanism being much greater than the temperature in the upper steaming mechanism, resulting in a large difference in the degree of heating of the food in the two steaming mechanisms.

[0070] Embodiment 3

[0071] A storage bin 5 is provided in the box body 1 below the heating plate 12, and the storage bin 5 is a pull-out type, and room temperature water is placed in the storage bin 5; the outlet of the gas outlet groove 22 extends into the storage bin 5; a conduit 51 is inserted into one side of the gas outlet groove 22 extending into the storage bin 5, and the conduit 51 extends into the water;

[0072] In this embodiment, the gas outlet groove 22 is an n-type groove, and the outlet of the n-type groove that is not provided with the conduit 51 also extends into the storage bin 5; a water pump 52 is installed in the storage bin 5, and the water outlet pipe of the water pump 52 is inserted into the outlet on the other side of the n-type groove;

[0073] In this embodiment, a circular groove 53 is formed on the top of the air outlet groove 22, and the circular groove 53 extends to the top of the box body 1; a plug 54 is engaged with the inner thread of the circular groove 53;

[0074] Specifically, when the steam discharged through the pressure relief valve enters the gas outlet groove 22, as the steam increases, the steam will enter the conduit 51 through the gas outlet groove 22 and be discharged from the conduit 51 into the water. When the steam contacts the water, it will turn into small water droplets and merge with the water. In this process, the steam can be prevented from directly dispersing into the air, resulting in the risk of scalding.

[0075] More specifically, when the pressure relief valve is exhausted, the control liquid water pump 52 works, and the water pump 52 can immediately pump water into the gas outlet groove 22. Since the gas outlet groove 22 is an n-type groove, the water entering the gas outlet groove 22 will flow along the gas outlet groove 22 and eventually flow into the storage bin 5. In this process, the circulating water can directly contact the steam in the gas outlet groove 22, turning it into small water droplets and merging with the water. At the same time, the circulating water can flush the gas outlet groove 22 to prevent the substances brought out by the steam from remaining in the gas outlet groove 22.

[0076] Furthermore, since the plug 54 is engaged with the inner thread of the circular groove 53 at the top of the air outlet groove 22, when the air outlet groove 22 needs to be cleaned, the plug 54 can be removed and the cleaning cotton can be inserted into the air outlet groove 22 to clean the air outlet groove 22;

[0077] Furthermore, since the telescopic tube 49 is inserted into the first through hole 31 and the second through hole 48 , when the telescopic tube 49 needs to be cleaned, the telescopic tube 49 can be pulled out from the first through hole 31 and the second through hole 48 to clean the telescopic tube 49 .

[0078] Embodiment 4

[0079] Two second electric telescopic rods 33 are fixedly mounted on the slide plate 3, and the extension rods of the two second electric telescopic rods 33 are fixedly mounted on the upper plate 46 and the lower plate 47 respectively;

[0080] In this embodiment, a pressure plate 201 is slidably connected in the air cavity 2, and a uniformly arranged spring is fixedly connected to one side of the pressure plate 201 away from the air inlet 24, and the other ends of the springs are fixedly connected in the air cavity 2;

[0081] The corner of the pressing plate 201 near the side thereof is rounded;

[0082] Specifically, since the two second electric telescopic rods 33 fixedly connected to the slide plate 3 are connected to the upper plate 46 and the lower plate 47 respectively, when it is necessary to push the upper plate 46 and the lower plate 47 closer to the food position, the second electric telescopic rods 33 can be controlled to extend. At the same time, the second electric telescopic rods 33 can resist the upper plate 46 and the lower plate 47, so as to avoid the air pressure between the two upper plates 46 being too high, which will push the two upper plates 46 away from each other.

[0083] More specifically, since a pressing plate 201 is provided in the air cavity 2, the existence of the pressing plate 201 can change the width of the air cavity 2, so that the steam can quickly fill the air cavity 2, so that the gas in the air cavity 2 can enter the two cooking mechanisms at the same time.
