Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical appliances, in particular to an air guide assembly and a cooking device. BACKGROUND

[0002] The cooking device generally comprises an air guide assembly for discharging the hot steam inside the cooking cavity of the inner container after cooking. Since the cooking device maintains a high temperature at the bottom during operation, for the existing cooking device which is mostly installed in an embedded manner, the high temperature of the cooking device is a test for the high-temperature resistance of the furniture located at the periphery of the cooking device. For example, in the long-time (40-60 minutes) cooking process of the cooking device, such as roasting sweet potatoes, the temperature of the cabinet contacted by the bottom of the cooking device is as high as 90℃, at which time the furniture made of poor high-temperature resistant plywood material has a safety hazard. Therefore, the air guide assembly of the cooking device is gradually moved from the top of the inner container to the bottom of the inner container.

[0003] However, the downward arrangement of the air guide structure requires adjustment of the air duct system inside the air guide plate. In order to achieve a good exhaust effect when the cooking device is used in the steaming function, the air guide plate is generally made into a downward trend air duct, which is just the opposite of the top exhaust structure. After the steaming function is completed, since the process of the cooking device is not convenient to set as long-time continuous exhaust, the residual water inside the air guide plate gradually accumulates at the exhaust port position under the action of gravity, causing water droplets to accumulate on the surface of the air guide plate, which not only causes inconvenience in cleaning, but also has the risk of damaging the cabinet due to water droplets on the cabinet.

[0004] In view of the problem of water droplets easily accumulating on the surface of the air guide plate in the above-mentioned downward air guide structure, the existing solutions of the existing cooking device each have their own problems. Specifically, some cooking devices are set in the program control to automatically enter a medium-temperature baking mode to dry the residual water in the air guide plate after the user finishes using the steaming function, which has the problem of high energy consumption; some cooking devices are provided with a safety coating such as a hydrophobic agent on the surface of the air guide plate, so that the water can be evenly and thinly distributed on the surface of the air guide plate to avoid water droplets, but the coating will fail after long-term use; some cooking devices try to change the material composition of the air guide plate and add other hydrophobic component materials to permanently achieve the effect of thin water distribution on the surface of the air guide plate, but there is no suitable material that has been verified to achieve the above-mentioned effect, and even if a suitable material is found, there may be the problem of high cost.

[0031] Referring to Figure 1 , Figure 1 A structural schematic diagram of a cooking device 10 in an embodiment of the present application is shown, and the cooking device 10 in an embodiment of the present application can be a steamer, a steam oven, or any existing device with cooking function. The cooking device 10 comprises the air guide assembly 100 in any of the embodiments described below, and further comprises an inner container 200 provided with a cooking cavity and a door body 300 covering the inner container 200. In combination Figure 2 , Figure 2 A cross-sectional schematic diagram of the cooking device 10 in an embodiment of the present application is shown, one end of the air guide channel 111 of the air guide assembly 100 is in fluid communication with the cooking cavity, and the other end is in communication with the outside of the cooking device 10, so that the water vapor in the cooking device 10 can be discharged to the outside of the cooking device 10 through the air guide channel 111 of the air guide assembly 100. In combination Figure 3 , the air guide assembly 100 is located below the inner container 200.

[0032] In combination Figure 4 to Figure 6 shown, Figure 4 to Figure 6 A structural schematic diagram of the air guide assembly 100 in an embodiment of the present application is shown, and the air guide assembly 100 in an embodiment of the present application can be used in the above-mentioned cooking device 10, but is not limited thereto. As Figure 4 and Figure 5 shown, the air guide assembly 100 comprises an air guide plate 110 and a heating element 120, the air guide plate 110 is provided with an air guide channel 111, the air guide channel 111 is used to make the fluid flow along the air guide channel 111 formed by Figure 2 andFigure 4 The airflow is shown in the guide path. (Example:) Figure 1 and Figure 2 As shown, the air guide assembly 100 also includes a partition 140, which is located between the air guide plate 110 and the inner liner 200. The partition 140 and the air guide plate 110 cover the air guide plate 110 to jointly enclose and form an air guide channel 111.

[0033] like Figure 4 and Figure 5 As shown, the heating element 120 is disposed on the air guide plate 110 and acts on the fluid flowing through the air guide channel 111 to heat the fluid flowing through the air guide channel 111. After the cooking appliance 10 has finished steaming, the heating element 120 acts on the fluid flowing through the air guide channel 111 to evaporate it through heat, thereby solving the problem of water accumulation inside the air guide plate 110 and preventing water from accumulating and dripping down the air guide opening 112 of the air guide plate 110, which could damage the cabinet. This achieves the effect of water droplets accumulating and dripping down below the air guide plate 110. The fluid may be water vapor or condensed water droplets. Figure 4 As shown, in this embodiment, the heating element 120 is a sheet-shaped heating element to avoid excessive interference of the heating element 120 with the flow of fluid.

[0034] like Figure 5 and Figure 6 As shown, in one embodiment, the heating element 120 is mounted on the air guide plate 110 facing the end face of the air guide channel 111 so as to directly act on the fluid flowing through the air guide channel 111, so that the heating element 120 directly contacts the water vapor and water droplets that may condense, thereby improving the heating efficiency of the heating element 120 on the water droplets.

[0035] In other embodiments, the heating element 120 is mounted on the end face of the air guide plate 110 away from the air guide channel 111, and the air guide plate 110 is made of heat-conducting material so that the heating element 120 indirectly acts on the fluid flowing through the air guide channel 111. At this time, the heat of the heating element 120 is transferred through the air guide plate 110 and then acts on the water vapor in the air guide channel 111.

[0036] like Figure 2 As shown, in one embodiment, the air guide plate 110 includes an air guide port 112 located at the end of the air guide channel 111, through which moisture inside the cooking cavity is discharged from the air guide port 112. The heating element 120 is positioned opposite the air guide port 112 to act on the fluid flowing through it, thereby preventing moisture from accumulating and dripping near the air guide port 112. Figure 1 to Figure 3 As shown, in this embodiment, the air vent 112 is located below the door body 300.

[0037] like Figure 4 and Figure 5As shown, in one embodiment, the air guide plate 110 includes an inclined plate 113 located upstream of the air guide port 112 on the air guide path. The inclined plate 113 is part of the air guide plate 110 for enclosing the air guide channel 111, and the inclined plate 113 is inclined at an upward slope and gradually widens in the direction toward the air guide port 112, so that the height of the air guide channel 111 gradually decreases and the width gradually increases in the direction toward the air guide port 112, thereby increasing the surface area on which the heating element 120 can be attached at the air guide port 112, thereby improving the heating efficiency of the heating element 120.

[0038] like Figure 4 and Figure 5 As shown, the air guide plate 110 also includes a flow guide plate 116 connected to the inclined plate 113 and located inside the air guide channel 111. The flow guide plate 116 has the tendency to guide the fluid in the air guide channel 111 to flow in a diffused manner, so that the fluid in the air guide channel 111 flows out evenly from the air guide port 112, thereby making the heating demand of the heating element 120 uniform.

[0039] like Figure 6 As shown, in one embodiment, the air guide plate 110 includes an upper plate 114 and a lower plate 115 spaced apart in the height direction, such as... Figure 4 and Figure 6 As shown, the lower plate 115 is connected to the inclined plate 113, and the gap between the upper plate 114 and the lower plate 115 forms an air guide 112. Figure 5 and Figure 6 In the illustrated embodiment, the heating element 120 is disposed on the end face of the lower plate 115 facing the upper plate 114, so that the heating element 120 directly contacts water vapor and potentially condensed water droplets, thereby improving the heating efficiency of the heating element 120 on the water droplets. In other embodiments, the heating element 120 may also be disposed on the end face of the lower plate 115 away from the upper plate 114, or on the end face of the upper plate 114 facing the lower plate 115, or on the end face of the upper plate 114 away from the lower plate 115.

[0040] In one embodiment, the heating element 120 is disposed on the end face of the lower plate 115 facing the upper plate 114, and the end face of the heating element 120 facing the upper plate 114 is provided with a wave-like structure to increase the resistance of fluid flow on the surface of the heating element 120, increase the residence time of fluid on the surface of the heating element 120, and avoid the fluid flow rate being too fast and failing to achieve the required heating effect.

[0041] like Figure 4 to Figure 6 As shown, in one embodiment, the air guide assembly 100 further includes a sensor 130, which is attached to the surface of the air guide plate 110 facing the air guide channel 111, and the sensor 130 is used to monitor the amount of water on the surface of the air guide plate 110, such as... Figure 4As shown, the sensor 130 is attached to the upper surface of the air deflector 110 to facilitate the collection of water droplets on the surface of the sensor 130 to monitor the water amount. The sensor 130 can be any component capable of monitoring the water amount on the surface in real time, such as a rain amount monitoring component used in the field of automobile front windshield, but is not limited thereto. The heating component 120 is configured to be triggered when the water amount monitored by the sensor 130 is greater than a preset water amount, so as to automatically turn on the heating component 120 when there is a risk of water droplet condensation and dripping, thereby improving the use convenience of the cooking device 10.

[0042] In one of the embodiments, the sensor 130 is located upstream of the heating component 120 on the air deflection path, and the sensor 130 is arranged adjacent to the heating component 120 to accurately obtain the water amount accumulation on the surface of the air deflector 110 near the heating component 120.

[0043] In one of the embodiments, the heating component 120 covers the air deflection passage 111 in a direction perpendicular to the height direction and perpendicular to the fluid flow direction, so as to heat and dry the air flow out of the air deflection passage 111, avoiding the dead angle where water droplets are likely to condense and fall.

[0044] As shown in FIGS. 1 and 2, in one of the embodiments, the sensor 130 covers the air deflection passage 111 in a direction perpendicular to the height direction and perpendicular to the fluid flow direction, so as to more comprehensively monitor the air flow out of the air deflection passage 111, avoiding the situation that the water vapor in the corner has condensed but is missed to be heated due to undetected. Figure 4 Figure 5 As shown in FIGS. 1 and 2, in one of the embodiments, the sensor 130 covers the air deflection passage 111 in a direction perpendicular to the height direction and perpendicular to the fluid flow direction, so as to more comprehensively monitor the air flow out of the air deflection passage 111, avoiding the situation that the water vapor in the corner has condensed but is missed to be heated due to undetected.

[0045] The air deflection assembly 100 provided in the above scheme solves the problem of water storage in the air deflector 110 by arranging the heating component 120 in the air deflection passage 111, so as to heat and evaporate the fluid flowing through the air deflection passage 111 after the cooking device 10 is finished steaming, thereby avoiding the water accumulation and dripping along the air deflection opening 112 of the air deflector 110 to damage the cabinet, and achieving the effect of water bead accumulation and dripping below the air deflector 110.

[0046] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradiction.

[0047] ​The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
