Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to cooking equipment. Background Art

[0002] Cooking equipment usually includes a door body and an inner pot with a cooking space. Taking a steamer as an example, the bottom of the door body is rotatably connected to the inner pot by a hinge, and a sealing ring is provided on the contact surface of the door body and the inner pot to seal the connection between the door body and the inner pot, thereby ensuring the temperature in the cooking space.

[0003] However, during the cooking process of the cooking equipment, due to the temperature difference between the cooking space and the outside, condensed water will continue to be generated on the inside of the door body. Under the action of gravity, the condensed water slides along the inner surface of the door body to the sealing ring between the door body and the inner pot. As the amount of water accumulates, the tongue of the sealing ring gradually cannot withstand it and deforms, causing water to leak from between the door body and the inner pot, causing the cooking equipment to leak and the sealing effect of the sealing ring to be poor. Summary of the invention

[0004] Based on this, it is necessary to provide a cooking device to address the problems of water leakage in the cooking device and poor sealing effect of the door body.

[0006] In one embodiment, the rotating rod rotates unidirectionally, and there is at least one contact position when the guide vane contacts the inner wall surface, and at the contact position, the tangential velocity of the guide vane is upward.

[0007] In one embodiment, the guide vane is arranged on the circumference of the rotating rod and extends radially of the rotating rod to protrude from the rotating rod, and the height of the guide vane in the radial direction of the rotating rod is not less than the distance between the rotating rod and the inner wall surface.

[0008] In one embodiment, an end of the guide vane away from the rotating rod in the radial direction of the rotating rod is a free end, and the thickness of the free end decreases from a direction close to the rotating rod to a direction away from the rotating rod.

[0009] In one embodiment, the rotating rod is disposed transversely spaced from the inner wall surface, and the rotating rod is rotatably connected to the inner container and transversely penetrates the opening.

[0010] In one embodiment, the guide vane extends in a transverse direction, and the transverse length of the guide vane is not less than 90% of the transverse length of the opening and not greater than the transverse length of the opening.

[0011] In one embodiment, there are multiple guide vanes, and the multiple guide vanes are distributed at intervals along the circumference of the rotating rod.

[0012] In one of the embodiments, adjacent guide vanes are equidistantly distributed.

[0013] In one of the embodiments, the guide device further comprises a driving member for driving the rotating rod to rotate, and the driving member is configured to drive any one of the guide vanes to contact the inner wall surface within a time period not exceeding 20 seconds.

[0028] See also Figure 1 , Figure 1 A schematic diagram of the decomposed structure of a cooking device 100 in an embodiment of the present application is shown. A cooking device 100 is provided in an embodiment of the present application. By way of example, the cooking device 100 may be a steamer, a steam oven, an oven, etc., or may be any existing cooking device 100.

[0029] like Figure 1 As shown, the cooking device 100 includes an inner pot 110 and a door body 120. The inner pot 110 includes a cooking cavity 111 with an opening 1111, and the cooking cavity 111 is used to hold food. The door body 120 covers the inner pot 110, and the door body 120 covers the inner pot 110, so that the door body 120 and the inner pot 110 together form a relatively closed cooking space for cooking food. The cooking device 100 processes the food in the cooking cavity 111, usually under conditions higher than room temperature, such as steaming, baking, etc. When the cooking device 100 cooks food, due to the temperature difference between the room temperature in the cooking cavity 111 and the room temperature outside the cooking device 100, condensed water is easily formed on the wall of the door body 120 facing the cooking cavity 111.

[0030] Combination Figure 2 As shown, Figure 2 A cross-sectional schematic diagram of a cooking device 100 in an embodiment of the present application is shown. In some embodiments, the door body 120 includes an inner wall surface 121 facing the cooking cavity 111, and when the door body 120 covers the inner pot 110, the inner wall surface 121 covers the opening 1111, such as Figure 1As shown, the inner wall surface 121 is arranged toward the cooking cavity 111. When the cooking device 100 cooks food, the temperature outside the door body 120 is low, and the temperature on the side of the door body 120 facing the cooking cavity 111 is high, thereby forming condensed water on the inner wall surface 121 facing the cooking cavity 111.

[0031] like Figure 1 and Figure 2 As shown, the cooking device 100 further includes a guide device 130, which acts on the condensed water formed on the inner wall surface 121 to collect the condensed water. The guide device 130 includes a rotating rod 131 rotatably arranged relative to the inner wall surface 121 and a guide vane 132 arranged on the circumference of the rotating rod 131, and the guide vane 132 rotates synchronously with the rotating rod 131. The rotation axis of the rotating rod 131 is parallel to the inner wall surface 121. When the rotating rod 131 rotates relative to the inner wall surface 121, the guide vane 132 intermittently contacts the inner wall surface 121 so as to scrape off the condensed water condensed on the surface of the inner wall surface 121, so that the condensed water located on the surface of the inner wall surface 121 and at the action position of the guide vane 132 is scraped off by the guide vane 132 and separated from the inner wall surface 121, thereby preventing the condensed water from directly sliding down along the inner wall surface 121 under the action of gravity and gathering in the seal between the inner wall surface 121 and the inner tank 110, thereby avoiding the poor sealing effect and water leakage caused by the condensed water collection seal formed by the inner wall surface 121.

[0032] The rotating rod 131 rotates in one direction. Figure 2 When the viewing angle is shown, the rotating rod 131 rotates clockwise. Figure 2 and Figure 3 , there is at least one contact position when the guide vane 132 contacts the inner wall surface 121, and at the contact position, the tangential velocity of the guide vane 132 is upward. Figure 2 and Figure 3 When in the position shown, the tangential speed of the guide vane 132 is upward, thereby driving the condensed water to slide along the guide vane 132 in the direction close to the rotating rod 131 through the guide vane 132, and as the guide vane 132 rotates unidirectionally with the rotating rod 131, the condensed water is poured into the cooking cavity 111, and the water in the cooking cavity 111 is discharged through the drainage device directly connected to the cooking cavity 111, thereby avoiding water leakage between the inner pot 110 and the door body 120 of the cooking device 100.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the guide vane 132 is arranged on the circumferential surface of the rotating rod 131 and extends along the radial direction of the rotating rod 131 to protrude from the rotating rod 131. The height of the guide vane 132 in the radial direction of the rotating rod 131 is not less than the distance between the rotating rod 131 and the inner wall surface 121, so that the guide vane 132 can contact the inner wall surface 121 at least at one position when the rotating rod 131 rotates, so as to scrape the condensed water on the inner wall surface 121.

[0034] In one embodiment, the guide vane 132 is made of a flexible material. When the guide vane 132 abuts against the inner wall surface 121, the guide vane 132 is deformed so that the height of the guide vane 132 does not need to be exactly in contact with the inner wall surface 121 but is not subjected to force, and the height of the guide vane 132 can have a larger production error. However, it is not limited to that the guide vane 132 needs to abut against the inner wall surface 121, and it can also be in contact without the existence of interaction force. Optionally, the guide vane 132 can be made of a flexible material such as rubber, or a metal sheet, etc.

[0035] Preferably, the height of the guide vane 132 in the radial direction of the rotating rod 131 is greater than the distance between the rotating rod 131 and the inner wall surface 121. At this time, when the guide vane 132 rotates with the rotating rod 131, there is at least one position where the guide vane 132 abuts against the inner wall surface 121 and there is an interaction force, thereby obtaining a better wiping effect.

[0036] like Figure 3 As shown, in one of the embodiments, the end of the guide vane 132 away from the rotating rod 131 in the radial direction of the rotating rod 131 is a free end 1321, and the thickness of the free end 1321 decreases from the direction close to the rotating rod 131 to the direction away from the rotating rod 131. On the one hand, the rated force during deformation is reduced to avoid the rigidity force when the guide vane 132 contacts the inner wall surface 121 to protect the inner wall surface 121, and it is also convenient for demolding during the production process. On the other hand, the inclined surface or curved surface formed by the reduced thickness of the free end 1321 allows the guide vane 132 to contact more with the inner wall surface 121, thereby obtaining a better effect of scraping condensed water.

[0037] like Figure 1 As shown, in one embodiment, the rotating rod 131 is arranged transversely separated from the inner wall surface 121, and the rotating rod 131 is rotatably connected to the inner pot 110 and transversely passes through the opening 1111. In other embodiments, a bracket protruding toward the inside of the cooking cavity 111 can also be provided on the door body 120, and the rotating rod 131 is rotatably connected to the bracket.

[0038] In one embodiment, the guide vane 132 extends in the transverse direction, and the transverse length of the guide vane 132 is not less than 90% of the transverse length of the opening 1111, and is not greater than the transverse length of the opening 1111. Figure 1 As shown, since the rotating rod 131 directly passes through the opening 1111 horizontally, the guide vane 132 is preferably equal to the length of the opening 1111, that is, the lateral ends of the guide vane 132 are flush with the inner wall of the liner 110 at the opening 1111. In other embodiments, the lateral length of the guide vane 132 can also be shortened due to assembly, rotation interference, etc., but the length of the guide vane 132 should not be less than 90% of the lateral length of the opening 1111 to ensure that most of the condensed water in the inner wall surface 121 can be scraped by the guide vane 132. In other embodiments, the guide vane 132 can also be a spiral structure.

[0039] In one embodiment, there are multiple guide vanes 132, and the multiple guide vanes 132 are distributed at intervals along the circumference of the rotating rod 131. In this embodiment, the number of the guide vanes 132 is 3. In other embodiments, the number of the guide vanes 132 can also be 1, 2 or more.

[0040] In one embodiment, adjacent guide vanes 132 are equidistantly distributed so that, under the premise that the rotation speed of the rotating rod 131 remains unchanged, the intervals of adjacent guide vanes 132 contacting or abutting against the inner wall surface 121 are consistent, thereby facilitating the selection of the rotation speed of the rotating rod 131 .

[0041] It takes time for condensed water to form on the inner wall surface 121. Generally, the time for condensed water to form is close to 30 seconds. When the rotation speed of the guide blade 132 is fast enough, the condensed water will be thrown into the cooking cavity 111 under the action of centrifugal force. In one embodiment, the guide device 130 further includes a driving member 133 for driving the rotating rod 131 to rotate. The driving member 133 is configured to drive any guide blade 132 to contact the inner wall surface 121 every 20 seconds or less. Figure 2 and Figure 3 In the embodiment of the example, since the circumference of the rotating rod 131 is provided with three equally spaced guide vanes 132, Figure 2 and Figure 3 In the embodiment, the rotation speed of the rotating member driven by the driving member 133 is 1r / min, and in other embodiments not shown, when a guide vane 132 is provided on the circumference of the rotating rod 131, the rotation speed of the rotating member driven by the driving member 133 is 3r / min, which can also be inferred and calculated in other embodiments. It can be understood that when the rotation speed of the guide vane 132 is slow, after the guide vane 132 scrapes the condensed water on the inner wall surface 121, the condensed water will slide along the guide vane 132 toward the rotating rod 131 under the action of gravity, and when the guide vane 132 rotates to the side away from the inner wall surface 121 and tilts downward, the condensed water will slide along the guide vane 132 under the action of gravity and fall into the cooking cavity 111, which can also achieve the effect of scraping the condensed water and pouring it into the cooking cavity 111.

[0042] It can be understood that the guide vane 132 can only scrape the condensed water above the guide vane 132. In one embodiment, the guide vane 132 acts on the bottom end of the inner wall surface 121 so that the condensed water formed on the inner wall surface 121 first slides naturally on the inner wall surface 121 and then gathers on the guide vane 132, so that the guide vane 132 can scrape most of the condensed water on the inner wall surface 121, thereby reducing the condensed water that naturally slides into the seal.

[0043] In the above scheme, by providing the guide device 130, the rotatable guide vane 132 in the guide device 130 intermittently contacts the inner wall surface 121, so that the guide vane 132 scrapes the condensed water condensed on the surface of the inner wall surface 121, so that the condensed water located on the surface of the inner wall surface 121 and at the action position of the guide vane 132 is scraped by the guide vane 132 and separated from the inner wall surface 121, thereby preventing the condensed water from directly sliding down along the inner wall surface 121 under the action of gravity and gathering in the sealing member between the inner wall surface 121 and the inner liner 110. , thereby avoiding the problem of poor sealing effect and water leakage caused by the condensate collection seal formed by the inner wall surface 121. By setting the rotation direction of the guide vane 132, the guide vane 132 scrapes the condensate upward, and as the guide vane 132 rotates unidirectionally with the rotating rod 131, the condensate is poured into the cooking cavity 111. The water in the cooking cavity 111 is discharged through the drainage device directly connected to the cooking cavity 111, thereby avoiding water leakage between the inner pot 110 and the door body 120 of the cooking device 100.

[0044] 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.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
