Description

Technical Field

[0001] The invention relates to the technical field of steaming and baking cooking machines, in particular to an inner pot component and a steaming and baking cooking machine. Background Art

[0002] In order to achieve uniform heating of food by heat convection in the cavity, traditional cooking machines often adopt the method of hot air blower + hot air blower baffle. This method is implemented by fixing a hot air blower on the back of the cavity (usually the side of the cavity), with the direction of the fan blades blowing towards the direction inside the cavity, and surrounding the fan blades on both sides with heating devices such as heating tubes. The hot air blower baffle cover is set above the fan blades of the hot air blower to divide the inner pot into a fan chamber and a cooking chamber, and the middle and edge parts of the hot air blower baffle are respectively provided with air outlet and air inlet holes. When the cooking machine is working, the hot air blower rotates to suck the air from the cooking chamber into the fan chamber and discharge it from the air outlet again, so that an air flow circulation is formed in the inner pot. At the same time, the hot air blower heating tube takes out part of the heat generated by the heating tube to form hot air. The hot air is evenly blown into the cavity in a predetermined direction under the constraint of the hot air blower baffle, so as to achieve the design purpose of forming heat convection in the cavity to uniformly heat the food.

[0003] Since the hot air blower baffle faces the cooking chamber, when the user opens the door, the holes on the baffle come into view, which is extremely unsightly and difficult to clean. The existing corona-type solution still needs to open air outlet holes on the hot air blower baffle, and cannot maintain the integrity of the side of the inner pot facing the user. In addition, the air flow circulation in the inner pot in the existing hot air blower solution is not uniform. If a rotating structure is added like in a microwave oven to achieve uniform heating, it is also easy to cause other problems. For example, the rotating structure occupies the effective use space in the cooking chamber. In order to ensure that the food keeps rotating during cooking, the shape of the food to be cooked needs to be strictly restricted. These all affect the actual user experience. Summary of the invention

[0004] In the existing steam-bake cooking machine, a hole needs to be opened on the side of the hot air blower baffle facing the user, which makes cleaning inconvenient for the user, and this air flow circulation scheme is uneven. Therefore, it is necessary to provide an inner pot assembly and a steam-bake cooking machine.

[0005] Inner tank assembly, including:

[0006] The liner body has an air collecting groove concave from the rear wall, an air inlet located on the periphery of the air collecting groove and connected to the air collecting groove, and a plurality of air outlets located on two opposite side walls of the liner body;

[0007] An air extraction member, installed on the air collecting slot and connected to the air inlet; and

[0008] A flow guide member is installed on the inner tank body and is connected to the air extraction member and the plurality of air outlets.

[0009] With this arrangement, there are no openings on the side of the inner pot body facing the user within the user's field of view, so that the internal structures of the steam-bake cooking machine, such as the fan, circuit board, and wires, are not visible, thereby improving the visual integrity of the rear wall of the inner pot body, making it easier for users to clean, and avoiding the impact of oil stains remaining on the rear wall of the inner pot body during long-term use on food safety.

[0010] In one of the embodiments, the air inlet is located on a side of the air collecting groove close to the bottom wall of the inner tank body.

[0011] Such an arrangement can prevent detergent or clean water from dripping into the air collecting trough from the air inlet, thereby protecting the exhaust fan in the air collecting trough.

[0012] In one of the embodiments, the air collecting groove is located on a side of the rear wall of the inner container body close to the bottom wall to form a supporting step in the inner container body for supporting the storage tray.

[0013] With such a configuration, the rear wall of the inner pot body can also be used to support the placing tray, which increases the stability of the placing tray. In addition to being used to support the placing tray, the position of the air inlet is also closer to the bottom wall, which can guide the airflow to flow downward. The hot air flowing out from the air outlets on both sides of the inner pot will flow from top to bottom over the food to be cooked, forming an airflow path that wraps the food, extending the contact time between the bottom of the food and the flowing hot air, and improving the utilization efficiency of the circulating airflow. In other words, the uniformity of the airflow heating the food is improved.

[0014] In one embodiment, the exhaust component includes a fan cover, a fan body and a heating tube. The fan cover is provided on the air collecting groove to form an air collecting cavity. The fan body and the heating tube are respectively located in the air collecting cavity. The fan body is connected to the air inlet, and the guide component is connected to the air collecting cavity.

[0015] With such arrangement, the arrangement of the heating pipes performs temperature compensation on the circulating airflow, and the fan cover closes the air collecting chamber, which is beneficial to maintaining the airflow temperature.

[0016] In one of the embodiments, the fan cover includes a cover shell having an installation window and a mounting plate detachably covering the installation window, and the heating tube and the fan body are mounted on the mounting plate.

[0017] With such arrangement, the heating tube and the fan body can be taken out by disassembling the mounting plate, thereby facilitating self-cleaning, maintenance and replacement by the user.

[0018] In one of the embodiments, the inner tank assembly further includes a filter element covering the air inlet.

[0019] With such an arrangement, the filter element can absorb oil stains in time to prevent the exhaust element from being contaminated with oil stains, which is beneficial to extending the service life of the exhaust element and eliminating the problem of odor contamination when cooking different foods.

[0020] In one embodiment, multiple groups of air outlets are arranged in sequence from top to bottom along the side wall of the inner tank body, the guide member has an air inlet channel and multiple groups of exhaust channels connected to the air inlet channel, the air inlet channel is connected to the exhaust member, and each group of exhaust channels is connected to each group of air outlets.

[0021] With such an arrangement, the air flow circulation in the inner pot body is hierarchical, which is convenient for adapting to foods of different heights, or adapting to racks of different heights, and is beneficial to improving the uniformity of heating of the food to be cooked.

[0022] In one of the embodiments, the guide member also includes a wind valve connected to the air inlet channel and the multiple exhaust channels, the wind valve includes an air inlet and an air outlet arranged in an annular direction, the air inlet is connected to the air inlet channel, and the air outlet is used to selectively connect to one of the multiple exhaust channels.

[0023] With this arrangement, the air valve can be used to achieve air outlet at specific levels in the inner tank body, adapting to the needs of different heating methods.

[0024] In one embodiment, the air damper is rotatably mounted on the inner tank body.

[0025] With such an arrangement, the air damper has a smaller movable space, thus saving the internal space of the steam-bake cooking machine.

[0026] The present application also provides a steaming and baking cooking machine, comprising:

[0027] Cabinet assembly; and

[0028] As the liner assembly mentioned above, the liner assembly is installed on the box assembly.

[0029] With this arrangement, when the user opens the door, a complete rear wall is introduced into the user's sight, and there are no visual holes. The rear wall of the inner pot body can be wiped with confidence during cleaning. Since the air inlet faces downward and is spaced apart from the bottom wall, there is no need to worry about water entering the fan at the air inlet when wiping the rear wall, which greatly improves the cleaning experience. The air outlets are arranged in layers to meet diverse cooking needs. Under the adjustment of the air valve, the uniform heating of the food to be cooked can be ensured, thereby improving the cooking quality. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0044] In order to achieve uniform heating of food by heat convection in the cavity, traditional cooking machines often adopt the method of hot air blower + hot air blower baffle. This method is implemented by fixing a hot air blower on the back of the cavity (usually the side of the cavity), with the direction of the fan blades blowing towards the direction inside the cavity, and surrounding the fan blades on both sides with heating devices such as heating tubes. The hot air blower baffle cover is set above the fan blades of the hot air blower to divide the inner pot into a fan chamber and a cooking chamber, and the middle and edge parts of the hot air blower baffle are respectively provided with air outlet and air inlet holes. When the cooking machine is working, the hot air blower rotates to suck the air from the cooking chamber into the fan chamber and discharge it from the air outlet again, so that an air flow circulation is formed in the inner pot. At the same time, the hot air blower heating tube takes out part of the heat generated by the heating tube to form hot air. The hot air is evenly blown into the cavity in a predetermined direction under the constraint of the hot air blower baffle, so as to achieve the design purpose of forming heat convection in the cavity to uniformly heat the food.

[0045] Since the hot air blower baffle faces the cooking chamber, when the user opens the door, the holes on the baffle come into view, which is extremely unsightly and difficult to clean. The existing corona-type solution still needs to open air outlet holes on the hot air blower baffle, and cannot maintain the integrity of the side of the inner pot facing the user. In addition, the air flow circulation in the inner pot in the existing hot air blower solution is not uniform. If a rotating structure is added like in a microwave oven to achieve uniform heating, it is also easy to cause other problems. For example, the rotating structure occupies the effective use space in the cooking chamber. In order to ensure that the food keeps rotating during cooking, the shape of the food to be cooked needs to be strictly restricted. These all affect the actual user experience.

[0046] Based on this, it is necessary to provide an inner pot assembly and a steam-bake cooking machine that can ensure uniformity of airflow circulation while being convenient for users to clean.

[0047] See also Figures 1 to 4 , Figure 1 This is a schematic structural diagram of a steaming and baking cooking machine in one embodiment of the present invention. Figure 2 for Figure 1 The schematic diagram of the structure of the steam-bake cooking machine is shown as the side facing the user. Figure 3 for Figure 2 The cross-sectional view of the steam-bake cooking machine taken along the AA direction is shown. Figure 4 for Figure 1 A partial structural schematic diagram of a steam-bake cooking machine is shown. The steam-bake cooking machine provided in the present application includes an inner pot assembly and a box assembly 50, and the inner pot assembly is installed on the box assembly 50. The inner pot assembly provided in the present application includes an inner pot body 10, an exhaust member 20 and a guide member 30, the inner pot body 10 has an air collecting groove 101 concave from the rear wall, an air inlet 102 located on the peripheral side of the air collecting groove 101 and connected to the air collecting groove 101, and a plurality of air outlets 103 located on two opposite side walls of the inner pot body 10, the exhaust member 20 is installed on the air collecting groove 101 and connected to the air inlet 102, the guide member 30 is installed on the inner pot body 10 and connected to the exhaust member 20 and the plurality of air outlets 103, and the air inlet 102 is a grid design to prevent foreign matter from entering the air collecting groove 101. In this way, the side of the inner pot body 10 facing the user has no opening within the user's field of view, so the internal structures of the steam-bake cooking machine, such as the fan, circuit board, and wires, are not visible, which improves the visual integrity of the rear wall of the inner pot body 10, facilitates user cleaning, and avoids the oil stains remaining on the rear wall of the inner pot body 10 during long-term use that affect food safety. Optionally, in an embodiment provided in the present application, the air inlet 102 is located on the side of the air collecting trough 101 close to the bottom wall of the inner pot body 10, so that detergent or clean water can be prevented from dripping from the air inlet 102 into the air collecting trough 101, thereby protecting the exhaust fan in the air collecting trough 101. Optionally, in an embodiment provided in the present application, an air collecting groove 101 is located on one side of the rear wall of the inner pot body 10 close to the bottom wall to form a support step 104 inside the inner pot body 10 for supporting the storage tray. When viewed from the front of the steam-bake cooking machine, the air collecting groove 101 corresponds to a clearance boss 106 inside the inner pot body 10. The clearance boss 106 protrudes from the rear wall of the inner pot body 10. In addition to being used to support the storage tray, the position of the air inlet 102 is also closer to the bottom wall, which can guide the airflow to flow downward. The hot air flowing out from the air outlets 103 on both sides of the inner pot body 10 will flow from top to bottom through the food to be cooked, forming an airflow path that wraps the food, thereby extending the contact time between the bottom of the food and the flowing hot air, and improving the utilization efficiency of the circulating airflow.

[0048] See also Figure 3 and Figure 4, further, in order to prevent the fan from being contaminated with oil and prevent the oil from participating in the air circulation in the fan, in one embodiment provided in the present application, the liner assembly also includes a filter covering the air inlet 102 (the specific embodiment is not shown in the figure, the filter can be a filter net, or a filter element with a certain thickness, as long as it can cover the air inlet 102 and does not affect the air circulation), and the filter timely absorbs the oil to prevent the air extraction member 20 from being contaminated with oil, which is conducive to extending the service life of the air extraction member 20 and eliminating the problem of cross-flavor pollution when cooking different foods. In order to further facilitate the user's cleaning, the filter can be detachably installed at the air inlet 102 of the liner body 10. It can be understood that the filter can be installed inside the liner body 10, so that it is convenient for the user to directly remove the filter; the filter can also be installed in the air collecting groove 101 of the liner body 10, that is, the filter is integrated into the air collecting groove 101, so that the problem of air leakage from the air inlet 102 caused by frequent disassembly and assembly can be avoided.

[0049] See also Figure 4 and Figure 5 , Figure 5 for Figure 1 Schematic diagram of the structure of the air extraction member 20 and the flow guide member 30. Specifically, in one embodiment provided in the present application, the fan cover 21 includes a cover shell 211 with an installation window and a mounting plate 212 detachably covering the installation window, and the heating tube 23 and the fan body 22 are installed on the mounting plate 212, so that the heating tube 23 and the fan body 22 can be taken out by disassembling the mounting plate 212, thereby facilitating the user to clean, repair and replace by themselves, and when the filter element is located in the air collecting slot 101, it is also convenient to replace a new filter element. Optionally, in an embodiment provided in the present application, the exhaust member 20 further includes heat insulation plates located on both sides of the heating member, the air intake port 221 of the fan body faces the air inlet port 102 of the air collecting slot 101, the exhaust port 222 is arranged back to back with the air intake port 221, the heating tube 23 is arranged at the exhaust port 222, the heat insulation plate and the cover shell 211 are arranged at intervals to form an insulation cavity in the air collecting cavity 40, the existence of the insulation cavity can prevent the heat of other parts in the steaming and baking cooking machine from being transferred toward the fan body, the heat insulation plate is also used to guide the airflow at the air inlet port 102 to pass through the fan body, which is conducive to standardizing and optimizing the airflow path in the air collecting cavity 40, and preventing the hot air discharged from the exhaust port 222 of the fan body and heated by the heating tube 23 from flowing back to the air intake port 221 of the fan body.

[0050] See also Figure 3 , Figure 5 and Figure 6 , Figure 6 for Figure 5Schematic diagram of the structure of the middle guide member 30, specifically, multiple groups of air outlets 103 are arranged in sequence from top to bottom along the side wall of the inner pot body 10, the guide member 30 includes a pair of guide tubes 31 and a pair of diverter covers 32 arranged corresponding to two opposite side walls on the inner pot body 10, and a plurality of partition plates 33 are provided in the diverter cover 32 to form exhaust channels 302 corresponding to the multiple groups of air outlets 103. The guide tube 31 is provided with an air inlet channel 301 connected to the exhaust member 20 and the exhaust channel 302. In this way, the air flow circulation in the inner pot body 10 is hierarchical, which is convenient for adapting to foods of different heights, or adapting to racks of different heights, and is beneficial to improving the uniformity of heating of the food to be cooked. Optionally, in order to achieve air outlet at a specific level in the inner pot body 10, in an embodiment provided in the present application, the guide member 30 also includes a wind valve 34 connected to the air inlet channel 301 and multiple exhaust channels 302, and the wind valve 34 includes an air inlet 341 and an air outlet 342 arranged in an annular direction, the air inlet 341 is connected to the air inlet channel 301, and the air outlet 342 is used to be selectively connected to one of the multiple exhaust channels 302. In this way, the air inlet channel 301 and any one of the exhaust channels 302 are connected through the wind valve 34, so that air circulation at a specific level in the inner pot body 10 is achieved to adapt to the needs of different heating methods. In addition, from the perspective of the entire cooking process, switching different exhaust ducts in sequence through the wind valve 34 can further improve the uniformity of the air flow circulation in the inner pot body 10, prevent the problem of partial scorching of food due to a single air flow path, and help improve the cooking quality. Optionally, in the present application, the air valve 34 is rotatably mounted on the inner pot body 10. In this way, when the air duct is switched, the position of the air valve 34 is fixed, and its movable space is small, which saves the internal space of the steam-bake cooking machine. It can be understood that during the entire cooking process, the food can be heated evenly by periodically rotating the air valve 34. By adjusting the rotation cycle of the air valve 34, different parts of the food to be cooked can be heated in a targeted manner, enriching the heating mode and accurately adapting to the cooking needs of different ingredients.

[0051] See also Figure 2 , Figure 3 and Figure 6 Optionally, each exhaust channel 302 corresponds to at least one group of air outlets 103. Exemplarily, the multiple air outlets 103 are divided into three layers of air outlet areas: upper, middle, and lower. The flow guide 30 has three exhaust channels 302 and corresponds to the three layers of air outlet areas, respectively. The upper and middle air outlet areas correspond to two groups of air outlets 103, respectively, and the lower layer corresponds to one group of air outlets 103. The two opposite side walls of the inner pot body 10 also have multiple support ribs 105 corresponding to the multiple groups of air outlets 103. The storage tray can be selectively clamped on the support ribs 105 at different heights to meet the cooking needs of ingredients of different heights.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
