Description

Technical Field

[0001] The invention relates to the field of kitchen cooking equipment, in particular to a cooking utensil dedicated to a microwave oven. Background Art

[0002] With the acceleration of modern life, microwave ovens have become widely popular due to their ability to heat food quickly. Consumers hope to use microwave ovens not only to simply heat food, but also to perform diversified cooking, such as steaming, baking, boiling, etc. However, there are many limitations when using ordinary tableware in microwave ovens. Suitable cooking utensils can improve the energy efficiency of microwave ovens.

[0003] During the microwave heating process, for some dishes that need to be cooked in layers or keep food spaced apart, the food at the bottom tends to absorb too much microwave energy and heat up quickly, while the food on the top may not be able to fully absorb the microwaves because the microwaves are blocked by the food at the bottom, resulting in uneven heating, which prolongs the cooking time and reduces cooking efficiency. When placing food in a cooking vessel, it may be difficult to perform multiple cooking methods at the same time because the capacity of the cooking vessel is too small and it may not be possible to bake food on one layer and steam food on another layer. This limits the cooking function of the microwave oven and cannot meet the user's demand for cooking diversity. It will take up a large area when stored, making it inconvenient to store. During use, it may cause a waste of space and increase the difficulty of cleaning. When steaming food, if there is no folding bracket on the bottom of the unfolded layers, the bottom of the layers will be uneven. When heating in the microwave oven or placed on the table, the food will be placed on the uneven surface and the distance from the microwave source will be inconsistent, causing soup and ingredients to fall off, making it impossible to support the bottom of the unfolded layers. Over time, the layers on both sides will break, requiring special tools and accessories to replace, increasing maintenance costs and time, and requiring more time and effort to clean. Summary of the invention

[0015] Furthermore, each of the clamping blocks is arranged corresponding to the first connecting shaft, and the bottoms of the four second brackets are fixedly connected with anti-slip pads.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The lifting support mechanism provided in the present invention can solve the problem of uneven heating, prolonged cooking time and reduced cooking efficiency. After rising to a certain position, the first limit plate on the bottom end of the outer rod will contact the bottom wall of the placement plate to prevent the outer rod from escaping from the hole of the placement plate, thereby achieving the limiting effect, and rotating the second baking tray to the right side of the heat insulation box. When the rotated second baking tray and the placement plate are in the same horizontal plane, the second baking tray is slid downward to set the left side of the second baking tray in the groove on the right side wall of the heat insulation box. The effect of aligning the baking tray and the placing tray left and right, when the second baking tray is placed, the same effect is used to pull the first baking tray to slide upwards and slide to the left side of the heat-insulating box to be placed in the groove on the left wall of the heat-insulating box, aligned with the left side of the placing tray, so that the placing tray and the first baking tray and the second baking tray are on the same horizontal plane, to place different foods in different positions, and to provide sufficient space for foods that cannot be placed on one tray, thereby effectively ensuring that each layer can fully absorb microwave energy, avoiding the situation where the bottom is overcooked and the top is not cooked, and reducing the time required for cooking.

[0018] 2. The connection ring, the first limiting plate, the arc sleeve, the placement groove and the spring can solve the problem that the storage takes up a large area and is inconvenient. During use, it may cause space waste and increase the difficulty of cleaning. By pushing the arc sleeve upward, the second connection block on the rear side of the arc sleeve will rotate inside the second limiting plate, so that the first connection rod on the outer side of the second limiting plate is contracted inside the arc sleeve, and the outer periphery of the second limiting plate is the same diameter as the inner rod, so that the second baking tray or the connection ring on the outer side of the first baking tray can be taken out from the outside, so as to reduce the number of trays, change the overall width, etc. When the placement tray needs to be disassembled, the first connection blocks on the left and right sides of the placement tray are taken out from the inside of the hole slot block, and the placement tray can be taken out from the inside of the heat insulation box, so that each tray can achieve a separate use effect, and it is also convenient to clean each tray and use it for different effects, so as to effectively improve the heating efficiency. When you need to cook a large amount of food, such as heating up a whole dish for a family dinner, all the multiple layers can be unfolded to provide enough space to meet cooking needs, and can be easily placed in a smaller space, thus improving the utilization rate of kitchen space.

[0019] 3. The problem that the bottom support of the unfolded layers cannot be provided through the provision of the first bracket, the slide groove, the first connecting shaft, the support rod, the block and the anti-skid pad can be solved, which causes the layers on both sides to break over time and requires special tools and accessories to be replaced, increasing the maintenance cost and time, and requiring more time and effort to clean. When the first connecting shaft slides to a specific position, the block can clamp the first connecting shaft to prevent it from accidentally sliding, thereby fixing the angle and position of the second bracket. The anti-skid pads at the bottom of the four second brackets further enhance the stability of the baking tray to prevent shaking during placement, which may cause food to fall. When storing, the card block is pressed again to disengage the first connecting shaft from the card block and slide to the original position inside the slide groove, and the top of the second bracket is driven to rotate on the outside of the first bracket through the support rod and the second connecting shaft, so that the second bracket is rotated to the bottom of the first bracket for folding and storage, thereby effectively ensuring that the food remains stable during the cooking process and reducing maintenance costs. When the cooking utensils need to be carried out for use, the folded structure is also more compact and easy to carry, and the risk of damage due to collision during transportation can be reduced, thereby improving space utilization.

[0020] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] 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.

[0044] like Figure 1 - Fig. 9 As shown: a cooking vessel for microwave oven, comprising a heat-insulating box 1, a placing plate 2 is arranged inside the heat-insulating box 1, and a lifting support mechanism 3 is arranged in the hole grooves on the front and rear sides of the heat-insulating box 1;

[0045] The lifting support mechanism 3 includes: four bases 301, four slot blocks 307 and four first connection blocks 309. The outer side walls of the four bases 301 are fixedly connected to the slots on the front and rear sides of the heat insulation box 1. The tops of the four bases 301 are fixedly connected with guide rails 302. The bases 301 are fixed in the slots inside the heat insulation box 1 to support and fix the top guide rails 302, so that the guide rails 302 are fixed inside the heat insulation box 1, and the bottom of the sliding slot blocks 307 is limited by the bases 301. The inner front and rear side walls of each guide rail 302 are provided with guide rail slots 303, and the slot blocks 307 are limited to move up and down only along the direction of the guide rail slots 303, thereby ensuring the linearity and stability of the lifting of the placement plate 2.

[0046] A support rod 304 is fixedly connected to the hole grooves on the left and right sides of the interior of each guide rod 302, and a positioner 305 is rotatably connected to the outer side of each support rod 304. A limiting rod 306 is fixedly connected to the left and right sides of each guide rod 302, and the bottom of each two limiting rods 306 is set at the outer top of the two positioners 305. When the placement plate 2 is pulled up or down, the limiting rod 306 is also fixedly connected to the inside of the guide rod 302, and the bottom of each two limiting rods 306 is set at the outer top of the two positioners 305, which is used to limit the rotation range of the positioner 305 to ensure that it moves within the normal working range.

[0047] The top of each guide groove 303 is arranged at the bottom of each support rod 304, the front and rear side walls of each hole slot block 307 are connected to the two guide grooves 303, the bottom wall of each hole slot block 307 is arranged on the upper side walls of the two positioners 305, and the outer side of the right side wall of each hole slot block 307 is fixedly connected with an arc plate 308, and each arc plate 308 is arranged on the outer side wall of the guide rod 302. The four first connecting blocks 309 are fixedly connected to the front and rear sides of the placement plate 2. The first connecting blocks 309 fixedly connected to the front and rear sides of the placement plate 2 are inserted into the hole slot block 307, and the placement plate 2 forms an integral structure with the hole slot block 307.

[0048] The outer sides of the four first connecting blocks 309 are all arranged inside the four hole slot blocks 307, and the bottoms of the four hole slot blocks 307 are fixedly connected with the engaging blocks 310, and the bottoms of the four engaging blocks 310 are fixedly connected with the contact plates 311, and the left and right side walls of each contact plate 311 are arranged at the bottom of the two positioners 305. When the hole slot blocks 307 move up and down along the guide rods 302, the placement plate 2 is also lifted and lowered accordingly. The left and right side walls of the contact plates 311 are arranged at the bottom of the two positioners 305. When the placement plate 2 is in the lifting process, the contact plates 311 interact with the positioners 305. When the placement plate 2 rises or falls to a suitable position, the mechanical contact between the contact plates 311 and the positioners 305 will cause the positioners 305 to rotate to a specific position on the support rod 304, thereby jamming the contact plates 311, and realizing the fixation of the placement plate 2 at this height, so as to achieve the effect of a dinner plate, which can be placed on the dining table and inside the microwave oven.

[0049] like Figure 1 - Fig.10 As shown, a top cover 4 is provided on the top of the heat insulation box 1, and the top cover 4 is used to cover the top of the heat insulation box 1 to prevent dust and impurities from entering the interior of the heat insulation box 1 when not in use. The upper side walls of the top cover 4 are fixedly connected with a first hinge frame 5, and the two first hinge frames 5 are internally rotatably connected with a handle 6. The handle 6 is provided to facilitate lifting the entire heat insulation box 1 for use and storage.

[0050] A first baking tray 7 is arranged inside the heat-insulating box 1, and the bottom of the first baking tray 7 is arranged on the top of the placing tray 2, and a second baking tray 8 is arranged on the top of the first baking tray 7. The outer sides of the first baking tray 7 and the second baking tray 8 are fixedly connected with a connecting ring 9. The first baking tray 7 and the second baking tray 8 are arranged to achieve a multiple-layered effect, so as to place different foods that need to be placed separately and to provide sufficient expansion space for foods that cannot be placed on a single placing tray 2.

[0051] like Fig.10 - Fig.15 As shown, the left and right side walls of the placing plate 2 are penetrated and connected with outer rods 10, the bottom ends of the two outer rods 10 are fixedly connected with first limit plates 11, the top ends of the two outer rods 10 are slidably connected with inner rods 12, and the tops of the two inner rods 12 are fixedly connected with second limit plates 13, the outer side of the top end of the left inner rod 12 penetrates the left inner side of the connecting ring 9 connected to the outside of the first baking plate 7, and the outer side of the top end of the right inner rod 12 penetrates the right inner side of the connecting ring 9 connected to the outside of the second baking plate 8. The placing plate 2 can be connected to the connecting rings 9 on the outer sides of the first baking plate 7 and the second baking plate 8 through the outer rods 10 and the inner rods 12 in the hole grooves on the left and right sides of the placing plate 2, so that the first baking plate 7 and the second baking plate 8 can be rotated.

[0052] As shown in the upper part, when it is necessary to steam and bake multiple different foods and larger foods, first pull the second baking tray 8 inside the insulation box 1 upwards. While pulling, the connecting ring 9 on the outside will drive the second limiting plate 13 and the inner rod 12 to extend inside the outer rod 10, and drive the outer rod 10 to slide in the hole of the placement tray 2. When it rises to a certain position, the first limiting plate 11 on the bottom end of the outer rod 10 will contact the bottom wall of the placement tray 2 to prevent the outer rod 10 from detaching from the hole of the placement tray 2, thereby achieving the limiting effect, and rotate the second baking tray 8 to rotate to the right side of the insulation box 1. When the rotated second baking tray 8 and the placement tray 2 are in the same horizontal plane, slide the second baking tray 8 downward so that the left side of the second baking tray 8 is set in the groove of the right wall of the insulation box 1, so that the second baking tray 8 and the placement tray 2 are aligned left and right. When the second baking tray 8 is placed, the same effect is used to pull the first baking tray 7 to slide upward and slide to the left side of the insulation box 1 to be placed in the groove of the left wall of the insulation box 1 and aligned with the left side of the placement tray 2, so that the placement tray 2 and the first baking tray 7 and the second baking tray 8 are on the same horizontal plane, so as to place different foods in different positions and provide sufficient expansion space for foods that cannot be placed on one tray.

[0053] The two second limiting plates 13 are both arranged on the top of the outer connecting ring 9 of the first baking tray 7 and the second baking tray 8, and a second connecting block 14 is rotatably connected in the hole groove of each second limiting plate 13. The second limiting plates 13 are placed on the top of the connecting ring 9 on the outer sides of the first baking tray 7 and the second baking tray 8 to prevent the inner rod 12 from detaching from the hole groove of the connecting ring 9 on the outer sides of the first baking tray 7 and the second baking tray 8.

[0054] like Fig.12 - Fig.13 As shown, the outer wall of every four second connecting blocks 14 is fixedly connected with an arc sleeve 15, and the outer side of each second limiting plate 13 is provided with a first connecting rod 16, and every four first connecting rods 16 are correspondingly arranged with the inner part of every four arc sleeves 15, and by pushing the arc sleeve 15 upward, the second connecting block 14 on the rear side of the arc sleeve 15 will rotate inside the second limiting plate 13, so as to drive the first connecting rod 16 to slide inside the arc sleeve 15 to shrink, and change the diameter of the top of the second limiting plate 13, so that the second limiting plate 13 and the inner rod 12 at the bottom have the same diameter, and the second baking tray 8 or the first baking tray 7 can be disassembled to change the length or width of the smaller microwave oven, and each plate can be used and cleaned separately.

[0055] A placement slot 18 is provided inside the bottom end of each second limiting plate 13, and a connecting column 20 is fixedly connected inside each placement slot 18. The connecting column 20 is fixed and supported by the placement slot 18 inside the bottom end of the second limiting plate 13. Four second hinge frames 17 are fixedly connected to the bottom of each of the four second connecting blocks 14, and a spring 19 is rotatably connected inside each of the second hinge frames 17. The bottom end of each spring 19 is rotatably connected to the outside of the middle part of the connecting column 20. When the second connecting block 14 is driven to rotate by pulling out the arc sleeve 15, the second hinge frame 17 at the bottom is connected to the spring 19, and the spring 19 is pulled to extend upward, and the first baking tray 7 or the second baking tray 8 is taken out from the outside. When the arc sleeve 15 is released after taking it out, it will rebound and reset through the spring 19 to restore its original appearance.

[0056] like Fig.15 - Fig. 20 As shown, the bottom walls of the first baking tray 7 and the second baking tray 8 are fixedly connected with the first bracket 21, and the front, back, left and right sides of the four first brackets 21 are provided with slide grooves 22. The slide grooves 22 provided inside the first brackets 21 provide an area for the first connecting shaft 24 to slide inside the heat insulation box 1. The outer side of each first bracket 21 is rotatably connected with the second bracket 23, and the second bracket 23 in two directions slides on the outer sides of the left and right sides of the first bracket 21 in two directions. The inside of each slide groove 22 is slidably connected with the first connecting shaft 24.

[0057] like Fig.19 - Fig. 20 As shown, the front and rear ends of each first connecting shaft 24 are rotatably connected to a support rod 25, and the bottom walls of the two support rods 25 are rotatably connected to a second connecting shaft 26. The left and right ends of each second connecting shaft 26 pass through and are connected to the bottom of the second bracket 23. When the first connecting shaft 24 slides in the slide groove 22, the second bracket 23 is driven to rotate through the transmission of the support rod 25 and the second connecting shaft 26. The second bracket 23 can adjust its angle accordingly to maintain good contact with the desktop, etc.

[0058] Each second bracket 23 is rotatably connected to an internal block 27, and each block 27 is arranged corresponding to the first connecting shaft 24. The bottom of the four second brackets 23 is fixedly connected to an anti-skid pad 28. When the first connecting shaft 24 slides to a specific position, the block 27 can clamp the first connecting shaft 24 to prevent it from accidentally sliding, thereby fixing the angle and position of the second bracket 23. The anti-skid pads 28 at the bottom of the four second brackets 23 further enhance the stability of the baking tray to prevent shaking when placed, which may cause food to fall.

[0059] It should be noted that the present invention is a cooking utensil specially used for microwave ovens. First, guide grooves 303 are provided on the front and rear side walls inside each guide rod 302. The guide grooves 303 cooperate with the hole slot blocks 307 to limit the hole slot blocks 307 to move up and down only along the direction of the guide grooves 303, thereby ensuring the linearity and stability of the lifting and lowering of the placement plate 2. When the placement plate 2 needs to be lifted or lowered, the positioner 305 can change its state under the action of a specific mechanical structure. At the same time, a limiting rod 306 is fixedly connected to the guide rod 302. The bottom of each two limiting rods 306 is arranged on the outer top of the two positioners 305, which is used to limit the rotation range of the positioner 305 and ensure that it moves within a normal working range.

[0060] The first connecting block 309 fixedly connected to the front and rear sides of the placement plate 2 is inserted into the hole slot block 307, and the placement plate 2 forms an integral structure with the hole slot block 307. Therefore, when the hole slot block 307 moves up and down along the guide rod 302, the placement plate 2 also rises and falls accordingly. The left and right side walls of the contact plate 311 are arranged at the bottom of the two positioners 305. When the placement plate 2 is in the process of being lifted and lowered, the contact plate 311 interacts with the positioner 305. When the placement plate 2 rises or falls to a suitable position, the mechanical contact between the contact plate 311 and the positioner 305 will cause the positioner 305 to rotate to a specific position on the support rod 304, thereby locking the contact plate 311, and fixing the placement plate 2 at this height, so as to achieve the effect of a dinner plate, which can be placed on the dining table and inside the microwave oven.

[0061] Inside the heat-insulating box 1, the first baking tray 7 is located on top of the placement tray 2, and the second baking tray 8 is located on top of the first baking tray 7. The cooking flexibility is increased, and different types or different states of food can be cooked at the same time, and the three trays can be stored in a stacked manner for convenient storage.

[0062] When it is necessary to steam and bake multiple different foods or larger foods, first pull the second baking tray 8 inside the heat insulation box 1 upwards. While pulling, the connecting ring 9 on the outside will drive the second limiting plate 13 and the inner rod 12 to extend inside the outer rod 10, and drive the outer rod 10 to slide in the hole of the placement tray 2. When it rises to a certain position, the first limiting plate 11 on the bottom end of the outer rod 10 will contact the bottom wall of the placement tray 2 to prevent the outer rod 10 from escaping from the hole of the placement tray 2, thereby achieving the limiting effect, and rotate the second baking tray 8 to make it rotate to the right side of the heat insulation box 1. When the rotation When the second baking tray 8 is in the same horizontal plane with the placing tray 2 after moving, slide the second baking tray 8 downward so that the left side of the second baking tray 8 is set in the groove of the right wall of the heat insulation box 1, so that the second baking tray 8 is aligned with the placing tray 2 left and right. When the second baking tray 8 is placed, the same effect is used to pull the first baking tray 7 to slide upward and slide to the left side of the heat insulation box 1 to be placed in the groove of the left wall of the heat insulation box 1, and aligned with the left side of the placing tray 2, so that the placing tray 2 and the first baking tray 7 and the second baking tray 8 are in the same horizontal plane, so as to place different foods in different positions and provide enough space for foods that cannot be placed on one tray.

[0063] When it is necessary to store and use a smaller microwave oven, first, when storing, pull the unfolded first baking tray 7 upwards so that the bottom of the first baking tray 7 leaves the groove on the left wall of the heat insulation box 1, and then rotate the first baking tray 7 so that the first baking tray 7 enters the interior of the heat insulation box 1 and the top of the placement plate 2. When the first baking tray 7 is placed on the top of the placement plate 2, the second limiting plate 13 on the left will contact the upper side wall of the connecting ring 9 on the outside of the first baking tray 7 to prevent the inner rod 12 and the outer rod 10 from falling off. The same steps are used to pull the connecting ring 9 out of the groove on the right wall of the heat insulation box 1, and the rotating connecting ring 9 enters the interior of the heat insulation box 1 and the first baking tray 7. , to achieve the effect of stacking and placement. In addition, after the stacking is completed, first pull the connecting ring 9 upwards and drive the placement plate 2 to slide upwards, so that the hole slot blocks 307 on the front and rear sides of the placement plate 2 drive the contact plate 311 at the bottom to slide the top positioner 305 upwards and jam it, and then press the connecting ring 9 to drive the placement plate 2 and the hole slot block 307 to slide downward inside the guide rod 302, and make the hole slot block 307 detach from the top of the positioner 305, and make the contact plate 311 enter the guide groove 303 to slide, so as to slide downward as a whole, and store the device in the interior of the heat insulation box 1.

[0064] In addition, when using a smaller microwave oven, the dish may be too long or too wide to be inserted into the interior. First, the arc sleeve 15 is pushed upward so that the second connecting block 14 on the rear side of the arc sleeve 15 rotates inside the second limiting plate 13, so that the first connecting rod 16 on the outer side of the second limiting plate 13 shrinks inside the arc sleeve 15, so that the outer periphery of the second limiting plate 13 and the inner rod 12 have the same diameter, and the connecting ring 9 on the outer side of the second baking tray 8 or the first baking tray 7 is taken out from the outside to reduce the number of dishes, change the overall width, etc. When the placement tray 2 needs to be disassembled, the first connecting blocks 309 on the left and right sides of the placement tray 2 are taken out from the inside of the hole block 307, so that the placement tray 2 can be taken out from the inside of the heat insulation box 1, so that each tray can be used separately, and it is also convenient to clean each tray and use it for different effects.

[0065] When the arc sleeve 15 is pulled out to drive the second connecting block 14 to rotate, the second hinge frame 17 at the bottom is connected to the spring 19, and the spring 19 is pulled to extend upward, so that the first baking tray 7 or the second baking tray 8 is taken out from the outside. When the arc sleeve 15 is released after taking it out, it will rebound and return to its original appearance through the spring 19.

[0066] When 7 and 8 are unfolded, the bottom will be supported by 21 and 23.

[0067] The first connecting shaft 24 slides in the slide groove 22, and the support rod 25 rotatably connected at the front and rear ends thereof and the second connecting shaft 26 rotatably connected inside the bottom wall of the support rod 25 together form a linkage structure. When the first connecting shaft 24 slides in the slide groove 22, the second bracket 23 is driven to rotate through the transmission of the support rod 25 and the second connecting shaft 26, and the second bracket 23 can adjust the angle accordingly to maintain good contact with the desktop or the like.

[0068] When the first connecting shaft 24 slides to a specific position, the block 27 can clamp the first connecting shaft 24 to prevent it from accidentally sliding, thereby fixing the angle and position of the second bracket 23. The anti-slip pad 28 at the bottom of the four second brackets 23 further enhances the stability of the baking tray to prevent shaking when placed, which may cause food to fall.

[0069] When storing, the block 27 is pressed again to disengage the first connecting shaft 24 from the block 27 and slide to its original position inside the slide groove 22, and the top of the second bracket 23 is driven to rotate on the outside of the first bracket 21 through the support rod 25 and the second connecting shaft 26, so that the second bracket 23 is rotated to the bottom of the first bracket 21 for folding and storage.
