[0047] In one exemplary embodiment:

[0048] like Figure 1 as well as Figure 2 As shown, an embodiment of the present invention provides an oven 1, which includes a baking chamber 11, a refrigerator chamber 12, and a conveying mechanism 2;

[0049] The baking chamber 11 and the refrigerator chamber 12 are integrally formed. The conveying mechanism 2 is installed inside the oven 1 and is used to convey food from the refrigerator chamber 12 to the baking chamber 11.

[0050] Optionally, the oven 1 is provided with a baking chamber 11 and a refrigerator chamber 12 from top to bottom.

[0051] Optionally, the oven 1 is provided with a baking chamber 11 and a refrigerator chamber 12 from right to left.

[0052] In this embodiment, the oven 1 integrates the baking chamber 11 and the refrigerator chamber 12. According to user habits, the baking chamber 11 and the refrigerator chamber 12 are arranged sequentially from top to bottom. The baking chamber 11 is used for baking food, and the refrigerator chamber 12 is used for refrigerating food. The oven 1 provides two different functions, and users can choose the function they need. Alternatively, users can refrigerate some food first and then bake it to achieve the best taste.

[0053] In some alternative embodiments, such as Figures 3-9 As shown, oven 1 also includes a drive mechanism 3;

[0054] The baking chamber 11 and the refrigerator chamber 12 are separated by an openable partition wall 15; the drive mechanism 3 drives the partition wall 15 to close or open.

[0055] When the partition wall 15 is closed, the baking chamber 11 and the refrigerator chamber 12 are sealed and separated; when the partition wall 15 is open, the baking chamber 11 and the refrigerator chamber 12 are connected.

[0056] Optionally, the partition wall 15 is made of rock wool and covered with a layer of sheet metal.

[0057] Optionally, the drive mechanism 3 includes a drive motor 31, for example, the drive motor 31 may be a motor of model ZYTD-60SRZ-R2 manufactured by Zhengke.

[0058] Optionally, a passage 14 exists between the baking chamber 11 and the refrigerator chamber 12, with a partition wall 15 disposed in the passage 14.

[0059] Optionally, when the partition wall 15 includes two sub-partition walls 151, the two sub-partition walls 151 are symmetrically arranged. Because the two sub-partition walls 151 are symmetrically arranged, there is a gap between them, which does not affect the temperature difference between the refrigerator compartment 12 and the baking compartment 11. Two positioning blocks 16 are provided in the channel 14 below the two partition walls. One positioning block 16 is located at one end of the gap along its length, and the other positioning block 16 is located at the other end of the gap along its length. The positioning blocks 16 are integrally formed with the channel 14. A rotating shaft 1511 is provided at the ends of the two sub-partition walls 151 that are far apart from each other. Since the two sub-partition walls 151 and the drive motor 31 are symmetrically arranged, they are described from one side only. The rotating shaft 1511 is integrally formed with the sub-partition wall 151, and the sub-partition wall 151 is hinged to the oven 1 via the rotating shaft 1511. The sub-partition wall 151 can rotate around the rotating shaft 1511. The oven 1 has a cavity on its back to accommodate the drive motor 31. One end of the rotating shaft 1511 on the partition wall 151 enters the cavity to accommodate the drive motor 31. The output shaft of the drive motor 31 is welded to the rotating shaft 1511 that enters the cavity to accommodate the drive motor 31. The cavity to accommodate the drive motor 31 is sealed with an elastic rubber gasket to prevent insects or dust from entering.

[0060] Optionally, when the partition wall 15 is a single piece, a pivot 1511 is provided at one end of the partition wall 15 away from the bottom surface of the oven 1. The pivot 1511 is integrally formed with the partition wall 15, and the partition wall 15 is hinged to the oven 1 via the pivot 1511, allowing the partition wall 15 to rotate around the pivot 1511. A cavity for accommodating the drive motor 31 is provided on one side of the oven 1. One end of the pivot 1511 on the partition wall 15 enters the cavity for accommodating the drive motor 31, and the output shaft of the drive motor 31 is welded to the pivot 1511 entering the cavity for accommodating the drive motor 31. The cavity for accommodating the drive motor 31 is sealed with an elastic rubber gasket to prevent insects or dust from entering.

[0061] In this embodiment, the space of the baking chamber 11 and the space of the refrigerator chamber 12 are connected or sealed by opening or closing the partition wall 15. A drive motor 31 drives the partition wall 15 to rotate, connecting the baking chamber 11 and the refrigerator chamber 12, facilitating the transfer mechanism 2 to transport food from the refrigerator chamber 12 to the baking chamber 11. This reduces the time that refrigerated food is exposed to air, maximizing the preservation of the food's refrigeration temperature. This, in turn, ensures the quality and texture of the baked food.

[0062] In some alternative embodiments, such as Figures 3-6 , Figure 10 As shown, the baking chamber 11 is vertically positioned directly above or below the refrigerator chamber 12, and the top of the oven 1 has a cavity 17 for accommodating the conveying mechanism 2.

[0063] The conveying mechanism 2 includes a lifting mechanism 21, which is used to lift or lower food in the refrigerator compartment 12 into the baking compartment 11.

[0064] Optionally, the baking chamber 11 is vertically positioned directly above the refrigerator chamber 12, and the top of the oven 1 has a cavity 17 for accommodating the conveyor mechanism 2.

[0065] Optionally, the lifting mechanism 21 includes a power motor 23, a traction rope 4, and a magnetic attraction component 5; for example, the power motor 23 can be a dual-shaft motor of model YSK-550-4B2 manufactured by Changzhou Jiayi Electric Co., Ltd. Two traction ropes 4 are respectively provided on the two output shafts of the power motor 23. Taking one output shaft as an example, one traction rope 4 is located on one side of the length direction of the output shaft, and the other traction rope 4 is located on the other side of the length direction of the output shaft. For ease of explanation, one traction rope 4 is used as an example. The traction rope 4 is made of steel wire, and a rubber tube is provided on its outer surface. The rubber tube can prevent the traction rope 4 from winding on the output shaft of the power motor 23 and causing mutual contact, thus preventing current interference. The rubber tube can deform along with the steel wire. The middle part of the traction rope 4 is bonded to the output shaft of the power motor 23, and one end of the traction rope 4 is connected to the power supply 6. The other end of the traction rope 4 passes through the through hole 121 on the oven 1, so that the other end of the traction rope 4 enters the baking chamber 11 from the cavity 17 and is welded to the magnetic attraction component 5.

[0066] Optionally, the magnetic assembly 5 includes an adsorption element 51 and an adsorbed element 52. Both the adsorption element 51 and the adsorbed element 52 are cylindrical iron blocks. The other end of the traction rope 4 is welded to the adsorption element 51, and the adsorbed element 52 is adhered to the four corners of the baking tray 120. The baking tray 120 is a rectangular baking tray 120, which can be made of metal. Of course, the baking tray 120 can also be regarded as the baking tray 120 and the adsorbed element 52 being integrally formed, with the baking tray 120 being the adsorbed element.

[0067] The suction element 51 is energized by the traction rope 4, which makes the suction element 51 magnetic. When the suction element 51 approaches the object to be suctioned 52, the suction element 51 and the object to be suctioned 52 are magnetically connected due to the magnetic effect. When the partition wall 15 is opened, the baking tray 120 in the refrigerator compartment 12 is transferred to the baking chamber 11 by the magnetic attraction of the magnetic attraction component 5 and the baking tray 120.

[0068] In this embodiment, the principle of using electromagnets to attract and process iron products is utilized, as seen in everyday applications such as car scrapping plants. This principle is cleverly applied to the oven 1, using a dual-axis motor 23 to ensure synchronized rising and falling speeds of the baking tray 120. Magnetic suction components 5 are placed at the four corners of the baking tray 120 to ensure more even distribution of the food's weight. The lifting mechanism 21 can stably lift the baking tray 120 from the refrigerator compartment 12 to the baking chamber 11.

[0069] In some alternative embodiments, such as Figures 7-9 , Figure 11 As shown, the baking chamber 11 is horizontally arranged on one side of the refrigerator chamber 12, and the oven 1 has a cavity 17 for accommodating the conveying mechanism 2.

[0070] The conveying mechanism 2 includes a horizontal power mechanism 22, which is used to move food in the refrigerator compartment 12 horizontally into the baking compartment 11.

[0071] Optionally, the baking chamber 11 is horizontally positioned to the right of the refrigerator chamber 12, and the bottom of the oven 1 has a cavity 17 for accommodating the conveying mechanism 2.

[0072] Optionally, the horizontal power mechanism 22 includes a power motor 23 and a traction rope 4; the refrigerator compartment 12 and the baking compartment 11 each have two through holes 121 connecting cavities 17, and the edges of the through holes 121 are rounded to prevent the through holes 121 from wearing down the traction rope 4. For example, the power motor 23 can be a dual-shaft motor of model YSK-550-4B2 manufactured by Changzhou Jiayi Electric Appliance Co., Ltd. A rotating rod 18 is provided on the side of the cavity 17 near the baking chamber 11. The rotating rod 18 is cylindrical and has a fixed pulley 181. The fixed pulley 181 is coaxial with the rotating rod 18. The rotating rod 18 is fixed to the side wall of the cavity 17 through the bearing seat 19. Since the power motor 23 is a dual-shaft motor, its output shaft is used as an example. The traction rope 4 is a steel wire. The middle part of the traction rope 4 is welded to the output shaft of one end of the power motor 23. One end of the traction rope 4 passes through the through hole 121 and enters the refrigerator chamber 12 from the cavity 17. The other end of the traction rope 4 first passes around the fixed pulley 181 on the rotating rod 18, and then passes through the through hole 121 and enters the baking chamber 11 from the cavity 17. The end of the traction rope 4 entering the refrigerator chamber 12 is welded together with the other end of the traction rope 4 entering the baking chamber 11 to form a closed loop of steel wire coil. A moving plate 24 is installed inside the cold storage compartment 12. The moving plate 24 is a rectangular metal plate. One end of the moving plate 24 is welded to a set of traction ropes 4 inside the cold storage compartment 12, and the other end of the moving plate 24 is welded to another set of traction ropes 4 inside the cold storage compartment 12.

[0073] When the partition wall 15 is opened, the baking tray 120 in the refrigerator compartment 12 is transferred to the baking compartment 11 by placing the baking tray 120 on the motion plate 24.

[0074] In this embodiment, multiple methods are provided for horizontally moving the baking tray 120 in the refrigerator compartment 12 to the baking chamber 11, fully considering the user's needs. Users can choose the appropriate horizontal movement method based on their budget and specific requirements. The horizontal movement using a traction rope 4 allows the baking tray 120 to reciprocate between the refrigerator compartment 12 and the baking chamber 11; while the electric push rod method can only push the baking tray 120 from the refrigerator compartment 12 to the baking chamber 11.

[0075] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the oven 1 is provided with a baking chamber 11, a refrigerator chamber 12, and a vacuum storage chamber 13 from top to bottom; the three chambers of baking chamber 11, refrigerator chamber 12, and vacuum storage chamber 13 are integrally formed.

[0076] Specifically, the vacuum storage chamber 13 is slidably connected to the oven 1. Here, the vacuum storage chamber 13 can be regarded as a drawer, and a baffle 131 is provided at the opening of the drawer. When the baffle 131 covers the opening of the drawer, the baffle 131 can completely seal the opening of the drawer and form a sealed space. A limiting block 132 is integrally formed on the surface of the drawer with the opening, which limits the baffle 131. The limiting block 132 is L-shaped, and the notches of the two L-shaped limiting blocks are arranged opposite each other. The drawer has an air extraction port 133, which is connected to a vacuum pump 134. For example, the vacuum pump 134 can be a miniature vacuum pump 134 of the ZMY545672714858 series manufactured by Fengshadu. The connection between the vacuum pump 134 and the evacuation port 133 can be achieved using existing conventional connection methods. The structure of the evacuation port 133 is an existing structure. The location of the evacuation port 133 and the installation location of the vacuum pump 134 only need to be able to evacuate the vacuum storage chamber into a vacuum, so they will not be described in detail.

[0077] Optionally, the oven 1 is provided with a baking chamber 11, a refrigerator chamber 12, and a vacuum storage chamber 13 from right to left; the three chambers of baking chamber 11, refrigerator chamber 12, and vacuum storage chamber 13 are integrally formed.

[0078] In this embodiment, the oven 1 integrates a baking chamber 11, a refrigerator chamber 12, and a vacuum storage chamber 13 into one unit. Based on user habits, the baking chamber 11, refrigerator chamber 12, and vacuum storage chamber 13 are arranged sequentially from top to bottom. The baking chamber 11 is used for baking food, the refrigerator chamber 12 is used for refrigerating food, and the vacuum storage chamber 13 is used for preserving food. The oven 1 provides three different functions, allowing users to select the function that best suits their needs. Users can also refrigerate some food before baking to achieve the optimal taste. After baking, the food can be stored in the vacuum storage chamber 13.

[0079] According to a second aspect of the embodiments of the present invention, such as Figure 12 As shown, this embodiment of the invention also provides a method for controlling an oven 1, where the oven 1 is the oven 1 in any of the above optional embodiments. The steps of the method for controlling the oven 1 include:

[0080] 101. Obtain the first state parameters of the food in the refrigerator compartment 12;

[0081] 102. When the first state parameter of the food in the refrigerator compartment 12 meets the preset state parameter, the conveying mechanism 2 is started.

[0082] Optionally, the first state parameter in step 101 may include a temperature parameter and / or a weight parameter.

[0083] Optionally, the first state parameter includes a temperature parameter, which is the surface temperature of the food inside the refrigerator compartment 12.

[0084] like Figure 4 , Figure 7 As shown, an infrared thermometer 7 is installed on the side wall of the refrigerator compartment 12. For example, the infrared thermometer 7 can be an RS-WD-HW-I20 infrared thermometer manufactured by Jian Da Ren Ke. The sensing end of the infrared thermometer 7 is positioned directly opposite the center of the bottom of the refrigerator compartment 12, and the infrared thermometer 7 is fixed to the side wall of the refrigerator compartment 12 with screws. The feedback end of the infrared thermometer 7 is connected to the controller 8 of the oven 1. The controller 8 of the oven 1 is a commercially available controller 8, for example, the controller 8 of the Casarte oven 1S45TSAU1; of course, the controller 8 can also be an STC89C52 microcontroller. In this technical solution, there is no need to consider the running program code written to the controller 8.

[0085] The user places food into the baking tray 120, then positions the baking tray 120 in the center of the refrigerator compartment 12, closes the refrigerator compartment 12 door, and then touches the control panel 122 to select the option to detect the food temperature in the refrigerator compartment 12. The infrared thermometer 7 inside the refrigerator compartment 12 detects the surface temperature of the food, which is then set as the initial temperature. The infrared thermometer 7 feeds back the initial temperature to the controller 8. The infrared thermometer 7 continuously measures the temperature of the food and updates the temperature value on the control panel 122. When the initial temperature reaches the user's preset temperature value, the controller 8 controls the conveyor mechanism 2 to transfer the food from the refrigerator compartment 12 to the baking chamber 11.

[0086] Optionally, the first state parameter includes a weight parameter, and the temperature parameter is the surface temperature of the food inside the refrigerator compartment 12.

[0087] like Figure 3 , Figure 4 as well as Figure 9 As shown, a groove 1201 is made at the bottom of the refrigerator compartment 12. The pressure sensor 9 is adhered to the groove 1201, and a cover plate 1202 is placed above the groove 1201 to conceal the pressure sensor 9. Simultaneously, it must be ensured that when the baking tray 120 is placed on the cover plate 1202, the sensing end of the pressure sensor 9 will sense the weight and change of the baking tray 120 and feed this feedback to the controller 8. For example, the pressure sensor 9 can be a Freud DYZ-101 pressure sensor. The power cord of the pressure sensor 9 is connected to a power source, and the feedback end of the pressure sensor 9 is connected to the controller 8 via a signal line. In this technical solution, the pressure sensor 9 and the controller 8 transmit signals wirelessly; for example, the pressure sensor 9 can connect to the controller 8 via Bluetooth, WiFi, or other methods.

[0088] The user places food into the baking pan 120 and then places the baking pan 120 onto the bottom cover 1202 of the refrigerator compartment 12. The pressure sensor 9 senses the weight of the food and the baking pan 120 and feeds it back to the controller 8. The controller 8 displays the total weight of the food and the baking pan 120 as the initial weight value in the item weight display area of ​​the operation panel 122. The pressure sensor 9 continuously monitors the baking pan 120 and the food in it and constantly refreshes the value in the item weight display area. After the food and the baking pan 120 have been refrigerated in the refrigerator compartment 12 for a period of time, due to the low humidity and temperature of the air in the refrigerator compartment 12, water molecules in the air will condense into water droplets and adhere to the food or the baking pan 120, causing a change in the weight of the baking pan 120 and the food.

[0089] In this embodiment, the user can precisely control the baking process of food using oven 1. For example, if the user wants to eat grilled steak, they can first place the steak in the baking pan 120 in the refrigerator compartment 12 to chill it. The user can choose to chill it for a period of time to allow it to release its acidity. Appropriate low temperature can improve the texture of the steak. Infrared thermometer 7 can be used to detect the temperature of the steak. Similarly, if the user wants to eat pastries, they can first place the pastry dough in the refrigerator compartment 12 to chill it. The low temperature will lower the temperature of the dough, thus hardening the crust. Baking the dough at this temperature will result in a better texture for the pastry. The user can choose the control method of oven 1 based on their budget and needs. If the budget is sufficient, the user can choose oven 1 with functions that detect temperature and weight parameters.

[0090] An example of the installation and baking process of oven 1 in an exemplary embodiment:

[0091] In this technical solution, the refrigeration principle of the refrigerator compartment is the same as that of a refrigerator compartment. All mechanical parts used for refrigeration are installed in the cavity 17. The baking principle of the baking compartment is the same as that of an oven baking compartment. All mechanical parts used for baking and heating are installed in the cavity 17. As long as the oven's refrigeration and heating functions can be realized, there are no specific limitations on the installation positions of the refrigeration and heating mechanical parts in the cavity. Therefore, they will not be elaborated on here.

[0092] like Figure 1 , 3 As shown in Figures 4, 5, 6, and 10, a vertical oven is selected. This oven 1 has, from top to bottom, a baking chamber 11, a refrigerator chamber 12, and a vacuum storage chamber 13; these three chambers are integrally formed. A passage 14 exists between the baking chamber 11 and the refrigerator chamber 12, and a partition wall 15 is disposed within the passage 14. The partition wall 15 is configured in an optional embodiment, including two sub-partition walls 151. The conveying mechanism 2 is a lifting mechanism 21. The magnetic assembly 5 uses cylindrical iron blocks for both the adsorption element 51 and the adsorbed element 52, while the baking tray 120 is made of a material that cannot be attracted by a magnet. Four adsorbed elements 52 are adhered to the four corners of the baking tray 120. The configuration and connection of the control elements are existing technologies and can be understood in conjunction with the relevant content of the aforementioned embodiments; therefore, further details are omitted here.

[0093] Baking process:

[0094] This section uses grilling a steak as an example to illustrate the grilling process. Users can adjust the grilling settings according to the type of steak and their desired texture. For simplicity, let's say a user wants to grill a sirloin steak. The user places the sirloin steak in the grill pan 120, positioning it precisely in the center of the refrigerator compartment 12. Here, the center of the refrigerator compartment 12 is defined as the center of the cover plate 1202 covering the pressure sensor 9 inside the compartment. Of course, the user doesn't need to place the grill pan 120 perfectly in the exact center; slight tilting is acceptable. The user closes the refrigerator compartment 12 door and then selects the following options on the control panel 122: for example, if the user prefers a medium-rare steak, they select a surface temperature of 6°C, a grilling temperature of 200°C (medium heat) for the grilling chamber 11, and adjust the grilling time to 6 minutes. Then, they press the start switch. At this time, the infrared thermometer 7 inside the refrigerator compartment 12 will detect the surface temperature of the steak. The temperature of the steak will decrease as the time spent in the refrigerator compartment 12 increases. When the infrared thermometer 7 detects that the surface temperature of the steak has dropped to 6°C, the feedback end of the infrared thermometer 7 will send a signal to the controller 8, and the controller 8 will control the refrigerator compartment 12 to stop working.

[0095] Then, controller 8 controls drive motor 31 to operate, with one drive motor 31 rotating forward and the other rotating in reverse. Drive motor 31 drives the two partition walls 151 to open, connecting the refrigerator compartment 12 and the baking compartment 11 via the passage 14. Controller 8 controls power motor 23 to operate. Power motor 23 is a dual-axis motor, ensuring consistent and synchronized speed of the traction rope 4. When power motor 23 rotates forward, the end of the traction rope 4 connected to the suction piece 51 descends, reducing the number of coil turns on the output shaft at that end, while increasing the number of coil turns on the end of the traction rope 4 connected to the power supply 6. After five seconds of forward rotation of power motor 23, the suction piece 51 descends into the refrigerator compartment 12. Controller 8 then energizes the traction rope 4, making the suction piece 51 magnetic, utilizing the principle of an electromagnet. Because the suction piece 51 is magnetic, it automatically locates the object 52 on the baking tray 120. Controller 8 controls the motor 23 to reverse, causing one end of the traction rope 4 connected to the suction element 51 to rise, increasing the number of coil turns wound on the output shaft at that end, while decreasing the number of coil turns wound on the output shaft at the end of the traction rope 4 connected to the power supply 6. The traction rope 4 pulls the baking tray 120 from the refrigerator compartment 12 to the baking compartment 11. Simultaneously, controller 8 controls the drive motor 31 to close the two partition walls 151, which then abut against the positioning block 16. Controller 8 then stops the drive motor 31, and the partition walls 151 re-seal the refrigerator compartment 12 and the baking compartment 11. Controller 8 then controls the motor 23 to rotate forward, causing one end of the traction rope 4 connected to the suction element 51 to descend, decreasing the number of coil turns wound on the output shaft at that end, while increasing the number of coil turns wound on the output shaft at the end of the traction rope 4 connected to the power supply 6. After the motor 23 rotates forward for three seconds, the traction rope 4 lowers the baking tray 120 onto the partition wall 15, causing the tray 120 to press against the partition wall 15. The controller 8 then cuts off the power to the traction rope 4, causing the adsorption element 51 to lose its magnetism and separate from the adsorbed item 52. The controller 8 then reverses the motor 23, causing the end of the traction rope 4 connected to the adsorption element 51 to rise, increasing the number of coil turns wound on the output shaft at that end. However, the number of coil turns wound on the output shaft at the end of the traction rope 4 connected to the power supply 6 decreases. When the adsorption element 51 touches the top plate of the baking chamber 11, the controller 8 stops the motor 23 and bakes according to the preset baking conditions. When the baking chamber 11 completes baking according to the preset conditions, the controller 8 stops the oven 1. At this point, the user can immediately enjoy the baked steak, or place it in the bottom vacuum storage chamber 13 for later storage. Leftover steak can also be stored in the vacuum storage chamber 13.
