Technical Field

[0001] The present invention relates to a cooking device, in particular to an integrated steam oven and microwave oven. Background Art

[0002] With the continuous improvement of people's living quality, kitchen appliances are becoming more and more abundant. Microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. These kitchen appliance products not only have relatively single functions, each product needs to occupy a certain amount of kitchen space, but also the cost of purchasing them separately is high. In order to effectively utilize the kitchen space and reduce the purchase cost, at present, there has been disclosed in the prior art an integrated steam oven, microwave oven and oven, i.e., an integrated steam, roast and microwave oven. Existing integrated steam, roast and microwave ovens are all cabinet-embedded or desktop types. At present, there is no table-embedded integrated steam, roast and microwave oven. To adapt to various kitchen structures and meet different kitchen area requirements, the table-embedded integrated steam, roast and microwave oven has a very important role. From the structural characteristics of the table-embedded type, its exhaust system needs to be improved accordingly. In order to facilitate the taking and placing of the steam baking tray, it is also necessary to redesign a new structure to facilitate the user to place and take food, and avoid scalding the hand during the taking process. To sum up, it is necessary to further improve the existing integrated steam, roast and microwave oven. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is, in view of the above-mentioned prior art status quo, to provide an integrated steam oven and microwave oven with a reasonable space layout and exhausting air from the top exhaust port.

[0004] The second technical problem to be solved by the present invention is, in view of the above-mentioned prior art status quo, to provide an integrated steam oven and microwave oven that can realize the hot air and steam exhaust functions through one mechanism.

[0005] The third technical problem to be solved by the present invention is, in view of the above-mentioned prior art status quo, to provide an integrated steam oven and microwave oven that is convenient for taking and placing the steam baking tray and safe to use.

[0006] The technical solution adopted by the present invention to solve the above first technical problem is: the integrated steam oven and microwave oven includes a box body and an inner container disposed in the box body. A steam generating device and a microwave generating device are installed in the interlayer between the box body and the inner container, and a barbecue generating device is installed on the inner container. It is characterized in that: an upward-opening door body is installed above the box body, an exhaust port is opened on the top plate above the box body, a wind guiding cover is installed in the interlayer, an air outlet hole and a hot air hole for communicating with the wind guiding cover are opened on the inner container, and the top of the wind guiding cover has an air outlet connected to the exhaust port.

[0007] The steam generating device can have various structures. Preferably, the steam generating device includes a water tank assembly, a steam generator, a two-way water pump, and a condensate water box. The water outlet of the water tank assembly is communicated with the first port of the two-way water pump, the water inlet of the steam generator is communicated with the second port of the two-way water pump, the water inlet of the condensate water box is communicated with the water outlet at the bottom of the air guide cover, and the water outlet of the condensate water box is communicated with the third port of the two-way water pump. In this way, the steam generated by the steam generating device can smoothly enter the inner container, and the condensate water remaining in the air guide cover can also flow back to the condensate water box and then can flow back into the water tank for recycling.

[0008] More preferably, the water tank assembly, the steam generator, and the two-way water pump are all arranged on the left side of the inner container, and the air guide cover and the condensate water box are both installed on the front side wall of the inner container.

[0009] The microwave generating device can be installed in multiple positions. Preferably, the microwave generating device is arranged at the bottom of the cabinet and is entirely located on the right side of the inner container. The microwave generating device includes a high-voltage transformer, a high-voltage capacitor, a high-voltage fuse tube, a magnetron, and a waveguide. The waveguide is horizontally arranged, and the head of the waveguide extends under the inner container, and a stirrer is installed at the head of the waveguide. In this way, the microwave can enter the inner container from the bottom of the inner container.

[0010] To improve the cooking uniformity of grilling, the grilling generating device includes a front heating tube, a rear heating tube, and a hot air blower assembly. The front heating tube is installed on the front inner side wall of the inner container, the rear heating tube is installed on the rear inner side wall of the inner container, and the hot air blower assembly is installed on the air guide cover, and the fan blade of the hot air blower assembly extends into the air guide cover.

[0011] More preferably, a control panel for integrally controlling the working states of the steam generating device, the microwave generating device, and the grilling generating device is installed on the top plate, and the control panel is located on the left side or the right side of the inner container. In this way, the control panel enables the integrated machine to automatically switch arbitrarily among the steam box mode, the microwave oven mode, and the oven mode during a single cooking process. Therefore, the integrated machine has a high control integration degree, and the user can switch the working mode of the integrated machine during a single cooking to heat the food, so that different foods can have corresponding cooking modes, the types of foods that can be cooked are more abundant, and the cooking effect is better.

[0012] To enable the hot air and steam to be blown upward from the front top of the integrated machine, the air outlet holes and the hot air holes are both arranged on the front side wall of the inner container, the exhaust port is arranged on the front side of the upper edge of the front side wall of the inner container, the air guide cover is installed on the front side wall of the inner container, and the air outlet is located directly below the exhaust port.

[0013] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is as follows: in this integrated steam oven and microwave oven, a movable shielding member is installed in the air guide cover. In the steam mode, the movable shielding member moves to a position where it covers the hot air holes and opens the air outlet holes, and the air outlet holes are communicated with the air outlet. In the barbecue mode, the movable shielding member moves to a position where it opens the hot air holes and closes the air outlet holes, and the hot air holes are not communicated with the air outlet. In this way, the hot air function and the steam exhaust function can be realized by using the same mechanism, greatly reducing the component space and increasing the use efficiency of the mechanism.

[0014] The movable shielding member can have various structures. Preferably, the movable shielding member includes an air outlet hole shielding member and a hot air hole shielding member. The hot air hole shielding member is fixed below the air outlet hole shielding member. The air outlet hole shielding member and the hot air hole shielding member move synchronously up and down under the drive of a driving member. In the steam mode, the air outlet hole shielding member moves upward to open the air outlet hole, and the hot air hole shielding member moves upward to close the hot air hole. In the barbecue mode, the air outlet hole shielding member moves downward to close the air outlet hole, and the hot air hole shielding member moves downward to open the hot air hole.

[0015] In order to enable the hot air hole shielding member to smoothly close or open the hot air holes when moving up and down, the hot air holes are arranged in rows in the horizontal direction and are spaced apart from each other up and down in each row. The hot air hole shielding member is a hot air hole shielding plate, and strip-shaped ventilation holes are opened in the hot air hole shielding plate and are spaced apart from each other up and down. The strip-shaped ventilation holes correspond to the hot air holes in each row one by one. In the state where the hot air hole shielding plate moves upward, the strip-shaped ventilation holes are staggered from the corresponding row of hot air holes to close the hot air holes. In the state where the hot air hole shielding plate moves downward, the strip-shaped ventilation holes are aligned with the corresponding row of hot air holes to open the hot air holes.

[0016] Further preferably, the air guide cover has a main body part and a head and neck part provided above the main body part. The head and neck part gradually expands from bottom to top, and the top of the head and neck part forms the air outlet. The air outlet hole shielding member is an air outlet hole shielding block arranged in the head and neck part. In the state where the air outlet hole shielding block moves upward, an air outlet gap is left between the air outlet hole shielding block and the inner wall of the head and neck part, and the air outlet hole is communicated with the air outlet through this air outlet gap. In the state where the air outlet hole shielding block moves downward, the air outlet hole shielding block fits with the inner wall of the head and neck part to make the hot air holes not communicated with the air outlet.

[0017] Further preferably, the main body part is circular or approximately circular, and the hot air hole shielding plate is arranged in the main body part and has a shape adapted to the main body part.

[0018] In order to enable the driving member to drive the air outlet blocking block to move smoothly, the driving member is a wax motor installed on the front side wall of the inner tank. There are two wax motors located on both sides of the head and neck. The driving output end of the wax motor extends upward into the head and neck and is connected to both ends of the air outlet blocking block.

[0019] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is as follows: In this integrated steam oven and microwave oven, a steaming and baking rack is installed in the inner tank. A vertical guide rail and a horizontal guide rail are provided in the inner tank. The vertical guide rail is fixed on the inner wall of the inner tank. The horizontal guide rail is arranged on the vertical guide rail and can move up and down relative to the vertical guide rail. The steaming and baking rack is arranged on the horizontal guide rail and can move up and down synchronously with the horizontal guide rail. A connecting rod is connected between the door body and the horizontal guide rail. The upper end of the connecting rod is rotatably connected to the door body, and the lower end of the connecting rod is connected to the horizontal guide rail and can move horizontally along the horizontal guide rail. In this way, through the lifting structure of the steaming and baking rack, the problem that the steaming and baking rack is inconvenient to take and place is solved, and it is not easy to cause scalding during taking and placing, making it safer to use.

[0020] In order to enable the steaming and baking rack to move smoothly, there are four vertical guide rails respectively arranged at the four corners of the inner tank, and two horizontal guide rails respectively arranged on the left and right sides inside the inner tank. Correspondingly, there are two connecting rods. The upper ends of the connecting rods are connected to the left and right sides of the lower surface of the door body, and the lower ends of the connecting rods are connected to the corresponding side of the horizontal guide rail.

[0021] In order to guide the up and down movement of the horizontal guide rail, vertical guide grooves are opened on the vertical guide rail, and guide posts protruding outward from both ends of the horizontal guide rail extend into the vertical guide grooves.

[0022] In order to enable the lower end of the connecting rod to move along the horizontal guide rail, a horizontal guide groove is opened on the horizontal guide rail, and a sliding member extending into the horizontal guide groove is provided at the lower end of the connecting rod.

[0023] The connecting rod can have various structures. Preferably, the connecting rod includes an upper connecting rod and a lower connecting rod that can telescopically move relative to each other. In this way, when the door body rotates, the upper connecting rod and the lower connecting rod can telescopically move relative to each other, and finally the up and down movement of the steaming and baking rack is realized.

[0024] In order to enable the steaming and baking rack to support two steaming trays, the steaming and baking rack includes an upper support piece for supporting the upper steaming tray and a lower support piece for supporting the lower steaming tray.

[0025] As a preference for any of the above solutions, a steam inlet and a microwave inlet are opened on the inner tank. The steam inlet is communicated with the steam outlet of the steam generating device, and the microwave generated by the microwave generating device enters the inner part of the inner tank through the microwave inlet.

[0026] Compared with the prior art, the advantages of the present invention are as follows: The integrated steam oven and microwave oven adopts a built-in and countertop installation method, and has three independent functions: steam cooking, barbecue cooking, and microwave cooking. The structure is relatively novel. In addition, the exhaust port is arranged on the top plate above the box body, and the air guide hood is installed in the sandwich between the box body and the inner liner. In the steam mode, steam is discharged into the air guide hood through the air outlet holes on the inner liner, and then discharged upward from the exhaust port on the top plate of the box body, avoiding the steam blowing towards the user's body from the front, and providing a better user experience.

The steam inlet is communicated with the steam outlet of the steam generating device 3, and the microwave generated by the microwave generating device 4 enters the inside of the inner container 2 through the microwave inlet.

[0044] As Figure 15 shown, the integrated steam oven and microwave oven adopts a built-in or countertop installation structure. After installation, the top plate 7 above the box body 1 is flush with the kitchen countertop 16. An upward-opening door body 6 is installed on the top plate 7. An exhaust port 71 is opened on the top plate 7. The exhaust port 71 is in a strip shape and is horizontally arranged on the front side of the upper edge of the front side wall 20 of the inner container. As Figure 5 shown, a wind guide cover 8 is installed in the interlayer between the box body 1 and the inner container 2. The air outlet 81 of the wind guide cover 8 is communicated with the exhaust port 71 and is located directly below the exhaust port 71.

[0045] As Figure 2 shown, the steam generating device 3 in this embodiment includes a water tank assembly 31, a steam generator 32, a two-way water pump 33 and a condensate water box 34. The water tank assembly 31, the steam generator 32 and the two-way water pump 33 are all disposed on the left side of the inner container 2.

During cooking, the steam generated by the steam generating device 3 can smoothly enter the inner container 2. The steam in the inner container 2 passes through the air outlet 81 of the wind guide cover 8 and then is discharged outwards from the exhaust port 71. The condensate water remaining in the wind guide cover 8 can also flow back to the condensate water box 34 and then can flow back into the water tank to realize recycling.

[0046] As Figure 3As shown in the figure, the microwave generating device 4 of this embodiment is arranged at the bottom of the box body 1 and is entirely located on the right side of the inner container 2.

Among them, the waveguide 45 is horizontally arranged, and the head of the waveguide 45 extends under the inner container 2. A stirrer 46 is installed at the head of the waveguide 45, and a microcrystalline glass (not shown in the figure) is installed at the bottom of the inner container 2. During cooking, the microwave generated by the magnetron 44 enters the inner container 2 through the waveguide 45 after being stirred by the stirrer 46 to heat the food.

[0047] As Figure 4 shown, the barbecue generating device 5 of this embodiment includes a front heating tube 51, a rear heating tube 52, and a hot air blower assembly 53. Among them, the front heating tube 51 is installed on the front inner side wall of the inner container 2, the rear heating tube 52 is installed on the rear inner side wall of the inner container 2, and the hot air blower assembly 53 is installed on the air guide cover 8. The hot air blower assembly 53 includes a motor bracket 531, a motor 532, and a fan blade 533. Among them, the motor bracket 531 is installed on the front wall of the air guide cover 8, the motor 532 is installed on the motor bracket 531 and the motor output shaft extends into the air guide cover 8, and the fan blade 533 is located inside the air guide cover 8 and is installed on the motor output shaft, and the fan blade 533 extends into the air guide cover 8. During cooking, the front and rear heating tubes can be used for separate heating, or they can be heated simultaneously to improve the cooking uniformity of the barbecue. The motor 532 of the hot air blower assembly 53 rotates to drive the fan blade 533 to rotate, thereby stirring the hot air inside the inner container 2 to ensure the barbecue uniformity.

[0048] As Figures 5 to 9 shown, an air outlet hole 21 and a hot air hole 22 are opened on the front side wall 20 of the inner container. The air outlet hole 21 is the steam outlet and is located above the hot air hole 22. The air guide cover 8 is installed on the front side wall 20 of the inner container. The air guide cover 8 is located below the top plate 7 and covers the air outlet hole 21 and the hot air hole 22. The air guide cover 8 of this embodiment has a main body portion 82 and a neck portion 83 provided above the main body portion. The main body portion 82 is circular, the neck portion 83 gradually opens upward from bottom to top, and the top of the neck portion 83 forms an air outlet 81.

[0049] An active shielding member 9 is installed inside the air guide cover 8. The active shielding member 9 includes an air outlet shielding member and a hot air hole shielding member. The hot air hole shielding member is fixed below the air outlet shielding member, and the air outlet shielding member and the hot air hole shielding member move synchronously up and down under the drive of a drive member. In this embodiment, the air outlet shielding member is an air outlet shielding block 91 disposed in the head and neck portion 83 of the air guide cover 8, and the shape of the air outlet shielding block 91 is adapted to that of the head and neck portion 83. The hot air hole shielding member is a hot air hole shielding plate 92 disposed in the main body portion 82 of the air guide cover 8, and the shape of the hot air hole shielding plate 92 is adapted to that of the main body portion 82, that is, the hot air hole shielding plate 92 is circular. In this embodiment, the hot air holes 22 are arranged in rows in the horizontal direction and are spaced apart from each other up and down in each row. Strip-shaped ventilation holes 921 are formed in the hot air hole shielding plate 92 at intervals up and down, and the strip-shaped ventilation holes 921 correspond to the hot air holes 22 in each row one by one.

[0050] The drive member is a wax motor 93 installed on the front side wall 20 of the inner container. The wax motor 93 is located outside the air guide cover 8. There are two wax motors 93 and they are located on both sides of the head and neck portion 83. The drive output end of the wax motor 93 extends upward into the head and neck portion 83 and is connected to both ends of the air outlet shielding block 91. Under the drive of the wax motor 93, the air outlet shielding block 91 and the hot air hole shielding plate 92 move synchronously up and down.

[0051] As Figure 6 and Figure 7 shown, in the steam mode, the wax motor 93 drives the air outlet shielding block 91 and the hot air hole shielding plate 92 to move upward. After the air outlet shielding block 91 moves upward, the air outlet 21 is opened, and an air outlet gap 84 is formed between the air outlet shielding block 91 and the inner wall of the head and neck portion 83. The air outlet 21 is communicated with the air outlet 81 through the air outlet gap 84; at the same time, after the hot air hole shielding plate 92 moves upward, the strip-shaped ventilation holes 921 on the hot air hole shielding plate 92 are staggered from the corresponding rows of hot air holes to close the hot air holes 22. The steam in the inner container 2 is driven by the hot air blower assembly 53, enters the air guide cover 8 through the air outlet 21, and then is discharged from the exhaust port 71 through the air outlet 81 at the top of the air guide cover 8.

[0052] As Figure 8 and Figure 9 shown, in the barbecue mode, the wax motor 93 drives the air outlet shielding block 91 and the hot air hole shielding plate 92 to move downward, the air outlet 21 is closed, and the air outlet shielding block 91 is in contact with the inner wall of the head and neck portion 83. At the same time, the strip-shaped ventilation holes 921 are aligned with the corresponding rows of hot air holes to open the hot air holes 22. At this time, the hot air holes 22 are not communicated with the air outlet 81 of the air guide cover 8 due to the blocking of the air outlet shielding block 91. The hot air blower assembly 53 blows the air in the air guide cover 8 into the inner container 2 to stir the hot air inside the inner container 2 to achieve uniform baking and prevent heat from escaping from the air guide cover 8.

[0053] AsFigures 10 to 14 As shown in the figure, a steaming and baking rack 11, a vertical guide rail 12 and a horizontal guide rail 13 are installed inside the inner container 2. There are four vertical guide rails 12 which are respectively arranged at the four corners of the inner container 2. The vertical guide rails 12 are fixed on the inner wall of the inner container 2. Vertical guide grooves 121 are formed on the vertical guide rails 12. There are two horizontal guide rails 13 which are respectively arranged on the left and right sides inside the inner container 2. Guide columns 131 protruding outward are provided at both ends of the horizontal guide rail 13 and extend into the vertical guide grooves 121. The horizontal guide rail 13 can move up and down along the vertical guide rail 12. Horizontal guide grooves 132 are formed on the horizontal guide rail 13.

[0054] The steaming and baking rack 11 is fixed on the horizontal guide rail 13 and can move up and down synchronously with the horizontal guide rail 13. The steaming and baking rack 11 of this embodiment includes an upper support piece 111 and a lower support piece 112, which can be used to support two steaming trays up and down. The upper steaming tray 151 is placed on the upper support piece 111, and the lower steaming tray 152 is placed on the lower support piece 112.

[0055] The door body 6 is connected to the horizontal guide rail 13 through a connecting rod 14. There are two connecting rods 14. The upper ends of the connecting rods 14 are connected to the left and right sides of the lower surface of the door body 6, and the lower ends of the connecting rods 14 are connected to the corresponding side of the horizontal guide rail 13. The connecting rod 14 of this embodiment includes an upper connecting rod 141 and a lower connecting rod 142 that can telescopically move relative to each other. The upper end of the upper connecting rod 141 is rotatably connected to the front side of the door body 6. A sliding member 143 extending into the horizontal guide groove 132 is provided at the lower end of the lower connecting rod 142, so that the lower end of the lower connecting rod 142 can move horizontally along the horizontal guide rail 13.

[0056] The working principle of this automatic lifting mechanism for the steaming tray is as follows:

[0057] As Figure 10 shown, when the door body 6 is in the closed state, with the direction indicated by the arrow A in Figure 10 as the front direction, the sliding member 143 at the lower end of the lower connecting rod 142 is arranged at the rear end of the horizontal guide groove 132, and the steaming and baking rack 11 is in the lowest position. At this time, both the upper steaming tray 151 and the lower steaming tray 152 are located inside the inner container 2.

[0058] As Figure 11 and Figure 12 shown, when the door body 6 is in the process of being opened, driven by the door body 6, the connecting rod 14 makes a rotational movement and drives the horizontal guide rail 13 to move upward along the vertical guide rail 12. At the same time, the sliding member 143 at the lower end of the lower connecting rod 142 moves to the middle position of the horizontal guide groove 132, and the steaming and baking rack 11 moves upward synchronously with the horizontal guide rail 13. At this time, the upper steaming tray 151 and the lower steaming tray 152 move upward by a certain distance.

[0059] As Figure 13 and Figure 14As shown, the door body 6 is fully opened. Driven by the door body 6 and the connecting rod 14, the horizontal guide rail 13 moves upward to the highest position of the vertical guide rail 12. The sliding member 143 at the lower end of the lower connecting rod 142 moves to the front end of the horizontal guide groove 132. The steaming and roasting rack 11 moves upward synchronously with the horizontal guide rail 13 to the highest position. At this time, the upper steaming tray 151 and the lower steaming tray 152 rise above the inner container 2, facilitating the operator to take the steaming trays and reducing the risk of scalding.

[0060] In addition, when closing the door body 6, the connecting rod 14 rotates reversely, driving the horizontal guide rail 13 and the steaming and roasting rack 11 to move downward, and finally moving to the lowest position as shown in Figure 10 where the upper steaming tray 151 and the lower steaming tray 152 are completely hidden inside the inner container 2.

[0061] As shown in Figure 3 and Figure 4 In the integrated steam oven and microwave oven of this embodiment, a control panel 10 is installed on the top plate 7, and the control panel 10 is located on the right side of the inner container 2. The control panel 10 has a control device, a human-machine operation interface, and a display component. The human-machine operation interface and the display component are connected to the control device. The human-machine operation interface receives an external input signal and converts the input signal into an output signal that can be recognized by the control device. The control device receives the output signal and integrally controls the working states of the steam generating device, the microwave generating device, and the barbecue generating device according to the output signal. The display component displays the working states of the steam generating device, the microwave generating device, and the barbecue generating device.

[0062] This integrated machine has multiple cooking modes such as single steaming, single microwaving, single grilling, steam and microwave combination, steam and grill combination, grill and microwave combination, and steam, grill and microwave combination. The best cooking mode for various foods can be preset on the human-machine operation interface. Before working, select the cooking mode of the food to be heated. During working, the control device can control the integrated machine to automatically switch between any cooking modes during a single cooking process. In this way, the integrated machine has a high degree of control integration. Different foods can have corresponding best cooking modes. The rich cooking modes can meet the cooking of the vast majority of foods and achieve better cooking effects.
