Description

Technical Field

[0001] This utility model pertains to cooking equipment, specifically relating to a cooking device with adjustable height feet and an oil draining mechanism. Background Technology

[0002] A cooking device with a drain valve is used to remove grease and / or grease added to a baking pan during cooking, or grease produced by the food being heated, from the baking pan at least after cooking is complete for cleaning purposes. Generally, the baking pan is tilted at the end of cooking to allow the grease to drain out through the drain port.

[0003] Existing cooking equipment that can drain oil, such as Figure 1-2 As shown, the baking pan is tilted by the feet, which are not adjustable. Figure 1 As shown, when the baking pan is on a horizontal plane, it is always tilted. During cooking, the grease in the pan easily leaks out through the drain hole, making it difficult to retain the necessary grease. This situation is also reflected in… Figure 2 When the baking pan is horizontal, some of its feet are off the horizontal plane and maintain a distance H between them. Figure 1 In the diagram, dotted lines marked with arrows indicate the direction of oil drainage. Furthermore, to prevent the cooking equipment from tilting excessively due to the baking pan's tilt, such as... Figure 1 The tilt angle α of the baking pan shown is generally small, such as 1°. This small tilt angle is not conducive to the rapid flow of grease from the baking pan. Utility Model Content

[0004] This invention addresses the shortcomings of existing oil-draining cooking devices, where the baking pan is always tilted, making it difficult to retain the necessary oil during cooking and hindering the rapid drainage of oil from the pan at the end of cooking. It provides an adjustable-height foot and an oil-draining cooking device, allowing the tilt angle of the baking pan to be adjusted as needed, thus retaining the necessary oil during cooking and facilitating the rapid drainage of oil from the pan at the end of cooking.

[0005] To achieve the above objectives, the adjustable height feet of this utility model are characterized by comprising: The bottom cover has through holes extending vertically; The lifting feet are telescopically fitted into the through-hole of the bottom cover. When the lifting feet extend downwards, they support the bottom cover at a first height; when they retract upwards, they support the bottom cover at a second height. The bottom cover is higher when it is at the first height than when it is at the second height. Accordingly, the bottom cover can be supported at either the first or the second height as needed.

[0006] Preferably, the lifting foot includes a lifting rod, a first support portion fixed to the lower end of the lifting rod, and a second support portion fixed to the upper end of the lifting rod. The lifting rod telescopically passes through a through hole in the bottom cover. The first support portion is located below the through hole, and the second support portion is located above the through hole. When the lifting foot supports the bottom cover at a first height, the second support portion supports the bottom cover; when the lifting foot supports the bottom cover at a second height, the first support portion supports the bottom cover. This structure uses the first and second support portions to support the bottom cover at different heights, ensuring reliable support.

[0007] Preferably, the lifting foot is equipped with a first spring that applies an upward elastic force to it; The bottom cover includes a cover plate and a clip that is slidably fitted onto the cover plate. The clip is offset laterally toward the lifting foot by the elastic force of a second spring. The height-adjustable foot includes a reset member, which is slidably mounted on the upper end of the lifting foot and offsets upward relative to the second support by the elastic force of the third spring. When the lifting foot extends downward from the bottom cover supported at the second height, it overcomes the elastic force of the first spring and the second support pushes the clip laterally until the clip is locked on the upper side of the second support by the elastic force of the second spring, supporting the bottom cover at the first height. When the lifting foot extends downward from the bottom cover supported at the first height, the reset member pushes the clip laterally until the clip overcomes the elastic force of the third spring by the elastic force of the second spring, causing the reset member to move downward and abut against the second support. At this point, the lifting foot is released, and the lifting foot resets to the bottom cover supported at the second height by the elastic force of the first spring. The clip resets by the elastic force of the second spring, and the reset member resets by the elastic force of the third spring.

[0008] Therefore, it is easy to adjust the height-adjustable feet to the required height, and the operation is convenient.

[0009] Preferably, the clip engages with the second support and the reset member via a first inclined surface, allowing the second support and the reset member to push the clip open laterally. This first inclined surface disperses the external force applied to the clip, facilitating lateral movement of the clip, resulting in a compact structure and sensitive, accurate operation.

[0010] Preferably, the reset member has a second inclined surface so that the clip, by means of the elastic force of the second spring, overcomes the elastic force of the third spring, causing the reset member to move downward and abut against the second support portion. This second inclined surface can decompose the external force applied to the reset member, causing the reset member to move downward, resulting in a compact structure and sensitive and accurate operation.

[0011] Preferably, the radial profile of the lower end of the reset member is larger than the radial profile of the upper end of the second support portion, so that when the lifting foot is reset by the elastic force of the first spring, the reset member and the second support portion slide past the clip in sequence. This prevents the clip from being stuck on the upper side of the second support portion by the elastic force of the second spring when the reset member and the lifting foot are reset upwards, thus preventing the bottom cover from being supported at the first height.

[0012] Preferably, the clips are assembled in pairs onto the cover plate. The bottom cover can be reliably supported at the first height by the elastic force of the second spring on the upper side of the second support.

[0013] Preferably, the cover plate has a seat, the seat has a guide groove and a receiving hole, the clip is constrained by the cover in the guide groove, the clip has legs, and a second spring is supported on the legs and located in the receiving hole together with the legs. This ensures that the clip can move flexibly in its own assembly position and that the second spring applies appropriate elastic force to the clip.

[0014] Preferably, the lifting foot has a shaft section located above the second support portion, and the reset member is sleeved in the shaft section and axially confined within the shaft section. This allows the reset member to maintain its relative position to the lifting foot and move flexibly.

[0015] This utility model discloses a cooking device with oil drainage capability, comprising a body supported by multiple feet, a baking tray with an oil drain port, and an oil collection box below the drain port. The key feature is that some of the feet are height-adjustable feet. The body includes a bottom cover. When the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a first or second height, the baking tray tilts to drain oil from the drain port into the oil collection box. Accordingly, the tilt angle of the baking tray can be adjusted by adjusting the height-adjustable feet as needed, ensuring that the oil required for cooking is retained in the baking tray and that the oil drains quickly from the baking tray at the end of cooking.

[0016] In one embodiment, the height-adjustable feet and the oil drain port are located on opposite sides of the main body. When the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a first height, the baking pan tilts to drain oil from the oil drain port into the oil collection box. In particular, when the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a second height, the baking pan is horizontal.

[0017] In another embodiment, the height-adjustable feet and the oil drain port are located on the same side of the body. When the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a second height, the baking pan tilts to drain oil from the oil drain port into the oil collection box. In particular, when the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a first height, the baking pan is horizontal.

[0018] This utility model involves telescopically mounting a lifting foot to the through hole of the bottom cover. The lifting foot extends downward to support the bottom cover at a first height, and retracts upward to support the bottom cover at a second height. When the bottom cover is at the first height, it is higher than when it is at the second height.

[0019] This invention utilizes height-adjustable feet for some of the cooking equipment's base. When the cooking equipment is on a horizontal plane and the adjustable feet support the bottom cover at a first or second height, the baking pan tilts to drain oil from the drain port into the oil collection box. Accordingly, the tilt angle of the baking pan can be adjusted by adjusting the height-adjustable feet as needed, ensuring that the oil required for cooking is retained in the baking pan and that the oil drains quickly from the pan at the end of cooking.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0026] like Figure 6-14 As shown, the height-adjustable foot 100 includes a bottom cover 110, a lifting foot 120, and a reset member 130.

[0027] The bottom cover 110 has a through hole 111 extending in the vertical direction.

[0028] The lifting feet 120 are telescopically mounted to the through holes 111 in the bottom cover. The lifting feet 120 are as follows: Figure 10 As shown, the bottom cover 110 extends downwards to support the bottom cover 110 at the first height H1, and the lifting feet 120 extend downwards as shown. Figure 8 The upward retraction shown supports the bottom cover 110 at the second height H2. When the bottom cover 110 is at the first height, it is higher than when it is at the second height, that is, the first height H1 is greater than the second height H2.

[0029] Specifically, the lifting foot 120 includes a lifting rod 121, a first support portion 122 fixed to the lower end of the lifting rod, and a second support portion 123 fixed to the upper end of the lifting rod. The lifting rod 121 telescopically passes through a through hole 111 in the bottom cover. The first support portion 122 is located below the through hole 111, and the second support portion 123 is located above the through hole 111. To facilitate assembly and maintain structural strength, the first support portion 122 is integrally formed with the lifting rod 121, and the second support portion 123 is fastened to the upper end of the lifting rod 121 by fasteners such as screws. The first support portion 122 and the second support portion 123 limit the movement of the lifting rod 121, preventing it from disengaging from the through hole. The lifting foot 120 is as follows... Figure 10 When the bottom cover 110 is supported at the first height H1, it is supported by the second support part 123, and the lifting feet 120 are as shown. Figure 8 As shown, when the bottom cover 110 is supported at the second height H2, the bottom cover 110 is supported by the first support part 122. This structure uses the first support part and the second support part to support the bottom cover at different heights, providing reliable support.

[0030] In the illustrated structure, a first spring 124, which is a helical compression spring, acts on the lifting foot 120 to exert an upward elastic force. This first spring 124 is sleeved around the lifting rod 121, with its upper end supported by the second support portion 123 and its lower end supported by the bottom cover 110. The bottom cover 110 includes a cover plate 112 and a clip 113 slidably mounted on the cover plate. The clip 113 is offset laterally (perpendicular to the lifting rod 121) towards the lifting foot 120 by the elastic force of the second spring 119. In the illustrated structure, the second spring 119 is a helical compression spring laterally supported by the clip 113. The reset member 130 is slidably mounted on the upper end of the lifting foot 120 and is offset upward relative to the second support portion 123 by the elastic force of the third spring 132, causing the reset member 130 and the second support portion 123 to... Figure 7-8 The spacing S shown provides space for the clip to engage on the upper side of the second support 123. The third spring is a helical compression spring.

[0031] Among them, the lifting feet 120, etc. Figure 7-8 When the bottom cover 110 shown is supported at the second height H2 and extends downward, as Figure 9 The second support 123 pushes the clip 113 laterally open to overcome the elastic force of the first spring 134 until... Figure 10 The clip 113, using the elastic force of the second spring 119, locks onto the upper side of the second support portion 123, supporting the bottom cover 110 at a first height H1. The lifting foot 120... Figure 10 When the bottom cover 110 is supported at the first height H1 and extends downward, the reset member 130, as shown... Figure 11 As shown, push the clip 113 horizontally until... Figure 12-13 As shown, the clip 113, with the elastic force of the second spring 119, overcomes the elastic force of the third spring 132, causing the reset piece 130 to move downwards and rest against the second support part 123. From this point, the lifting foot 120 is released, and the lifting foot, with the elastic force of the first spring 124, ... Figure 14 Reset upwards as shown Figure 7-8 The bottom cover 110 is supported at a second height H2. The clip 113 is reset by the elastic force of the second spring 119, and the reset member 130 is reset by the elastic force of the third spring 132. Figure 14 As shown, during the upward reset of the lifting foot 120, the position where the reset member 130 abuts against the second support part 123 is via the clip. Since the reset member 130 abuts against the second support part 123, the distance S between the reset member 130 and the second support part 123 disappears. Therefore, the clip 113 will not lock on the upper side of the second support part 123 to support the bottom cover at the first height. Accordingly, it is convenient to adjust the height-adjustable foot to the required height, and the operation is convenient. The downward movement of the lifting foot can be achieved by pinching the first support part with your fingers and pulling it down.

[0032] In the illustrated structure, the clip 113 engages with the second support portion 123 and the reset member 130 via a first inclined surface 114, allowing the second support portion 123 and the reset member 130 to laterally push the clip 113 open. Given the structure of the clip, the first inclined surface 114 is located at one end of the clip 113. This first inclined surface can decompose the external force applied to the clip, causing the clip to move laterally, resulting in a compact structure and sensitive, accurate movement. The reset member 130 has a second inclined surface 131, allowing the clip 113 to overcome the elastic force of the third spring 132 by the elastic force of the second spring 119, causing the reset member 130 to move downwards and abut against the second support portion 123. Given the structural shape of the reset member, the second inclined surface 131 is embodied as the circumferential surface of the frustum of the reset member 130. This second inclined surface can decompose the external force applied to the reset member, causing the reset member to move downwards, resulting in a compact structure and sensitive, accurate movement.

[0033] like Figure 14 As shown, the radial profile of the lower end of the reset member 130 is larger than the radial profile of the upper end of the second support part 123 so that when the lifting foot 120 is reset by the elastic force of the first spring 124, the reset member 130 and the second support part 123 slide past the clip 113 in sequence, so as to prevent the clip 113 from being stuck on the upper side of the second support part 123 by the elastic force of the second spring 124 and supporting the bottom cover at the first height.

[0034] In the illustrated structure, clips 113 are assembled in pairs onto cover plate 112. The bottom cover can be reliably supported at the first height by means of the elastic force of the second spring, which locks it onto the upper side of the second support.

[0035] In the illustrated structure, the cover plate 112 has a seat 116, the seat 116 has a guide groove 117 and a receiving hole 118, the clip 113 is constrained in the guide groove 117 by the pressure cap 113a, the clip 113 has legs 115, and a second spring 119 is supported on the legs 115 and located in the receiving hole 118 together with the legs. This ensures that the clip can move flexibly in its own assembly position and that the second spring applies appropriate elastic force to the clip.

[0036] In the illustrated structure, the lifting foot 120 has a shaft segment 125 located above the second support portion 123. The reset member 130 is sleeved in the shaft segment 125 and axially confined within the shaft segment. Accordingly, the reset member maintains its relative position with the lifting foot and can move flexibly.

[0037] like Figure 3-4 The cooking appliance shown includes a body 200 supported by four feet 100, with the four feet located at the four corners of the bottom of the body 200. The body 200 is equipped with a baking tray 210, which has an oil drain 211. An oil collection tray 220 is located below the oil drain 211. Part of the feet 100 are... Figure 6-14 The adjustable-height base shown in the diagram includes a base cover 110 of the main body 200. When the cooking device is positioned on a horizontal plane 300 and the lifting feet 120 support the base cover 110 at a first height H1 or a second height H2, the baking pan 210 tilts to drain oil from the drain port 211 to the oil collection box 220. Accordingly, the tilt angle of the baking pan can be adjusted as needed by adjusting the adjustable-height base, so that the oil required for cooking is retained in the baking pan during cooking and the oil in the baking pan can be quickly drained out when cooking is finished.

[0038] The height-adjustable feet 100 and the oil drain port 211 are located on opposite sides of the body 200, such as Figure 3-5In the design, adjustable feet 100 are located at the two front corners of the bottom of the unit. The oil drain port 211 and oil collection box 220 are located at the rear of the unit 200. When the cooking device is on the horizontal plane 300 and the lifting feet 120 support the bottom cover 110 at a first height H1, the baking pan 210 tilts to quickly drain oil from the oil drain port 211 to the oil collection box 220. Specifically, when the cooking device is on the horizontal plane 300 and the lifting feet 120 support the bottom cover at a second height H2, the baking pan 210 is horizontal, retaining the necessary oil for cooking within the pan. Compared to existing technologies, when the lifting feet 120 support the bottom cover 110 at the first height H1, the tilt angle β of the baking pan 210 can be larger, such as reaching 3°, which is more conducive to draining oil from the oil drain port to the oil collection box. Figure 3 In the diagram, the direction of oil discharge is indicated by a dashed line marked with an arrow.

[0039] In other embodiments, the height-adjustable feet and the oil drain port are located on the same side of the body. For example, if the height-adjustable feet are located at the two front corners of the bottom of the body, and the oil drain port and oil collection box are located at the front of the body, then when the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a second height, the baking pan tilts to drain oil from the oil drain port into the oil collection box. In particular, when the cooking device is on a horizontal plane and the lifting feet support the bottom cover at a first height, the baking pan is horizontal.

[0040] The bottom of the feet is equipped with anti-slip pads 126 to prevent the cooking equipment from sliding and to keep the cooking equipment stable.
