DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0015] With reference to FIGS. 1 to 3, a lid device 10 of a vertical cutter mixer in accordance with the present invention is configured to close a top of a mixing barrel 20 and is configured to be pivotably connected to a side stand 30 next to the mixing barrel 20. The side stand 30 is located at a side of the mixing barrel 20. The mixing barrel 20 is connected to and is disposed above a tumbling base 40. The tumbling base 40 is rotatable relative to the side stand 30 around a horizontal tumbling shaft 45. A driving device is disposed in the tumbling base 40. A blade set is disposed in the mixing barrel 20 and is connected to the driving device. The blade set can be driven by the driving device to chop and stir food ingredients within the mixing barrel 20.

[0016] With reference to FIGS. 1 to 5, the lid device 10 comprises a lid body 11, a support member 13, and at least one linking member 15. The lid body 11 comprises a holder 12 at a top of the lid body 11. The support member 13 is disposed above the lid body 11, and is configured to be pivotably connected to the side stand 30 via an end of the support member 13. Each linking member 15 is disposed between the lid body 11 and the support member 13, is pivotably connected to the holder 12 via a first pivot member 16, and is pivotably connected to the support member 13 via a second pivot member 17. Each linking member 15 is pivotable relative to the holder 12 around the first pivot member 16 and is pivotable relative to the support member 13 around the second pivot member 17.

[0017] The at least one linking member 15 may comprise multiple linking members 15 spaced apart from one another, so a stable connection of the lid body 11 and the support member 13 can be provided with the multiple linking members 15. Preferably, the at least one linking member 15 comprises two linking members 15 arranged along the support member 13 at a spaced interval. A first distance between two ends of the two linking members 15 connected to the support member 13 is smaller than a second distance between two ends of the two linking member 15 connected to the holder 12. Specifically, the at least one linking member 15 comprises four linking members 15 divided into two sets in a side-by-side arrangement. Each set includes two of the linking members 15 arranged along the support member 13.

[0018] The holder 12 may have multiple first through holes 122 spaced apart from one another. The support member 13 may have multiple second through holes 132 spaced apart from one another. Each linking member 15 has a first connecting hole 151 and a second connecting hole 152 spaced apart each other. Each linking member 15 is pivotably connected to the holder 12 via the first pivot member 16 extending through the first connecting hole 151 and one of the first through holes 122 of the holder 12. Each linking member 15 is pivotably connected to the support member 13 via the second pivot member 17 extending through the second connecting hole 152 of the linking member 15 and one of the second through holes 132 of the support member 13. A distance between each adjacent two first through holes 122 is larger than a distance between each adjacent two second through holes 132. Therefore, the first distance between the two ends of the two linking members 15 connected to the support member 13 is smaller than the second distance between the two ends of the two the linking members 15 connected to the holder 12.

[0019] Specifically, the holder 12 comprises two mounting plates 121 extending parallel to the support member 13 and laterally spaced apart from each other. The support member 13 comprises two supporting arms 131 extending away from the side stand 30 and laterally spaced apart from each other. Each mounting plate 121 is connected to a respective one of the two supporting arms 131 via two of the linking members 15 arranged along the support member 13 at a spaced interval. Each mounting plate 121 has two said first through holes 122 formed therethrough and arranged along the support member 13. Each supporting arm 131 has two second through holes 132 formed therethrough and arranged along the support member 13. The distance between the two second through holes 132 is smaller than the distance between the two first through holes 122. Each of the linking members 15 is pivotably connected to one of the mounting plates 121 via the first pivot member 16 extending through the first connecting hole 151 of the linking member 15 and one of the first through holes 122 at the mounting plate 121. Each of the linking members 15 is pivotably connected to one of the two supporting arms 131 via the second pivot member 17 extending through the second connecting hole 152 of the linking member 15 and one of the second through holes 132 at the supporting arm 131. When the mixing barrel 20 is closed by the lid body 11, the two linking members 15 are inclined downwardly and gradually away from each other.

[0020] Furthermore, the support member 13 may comprises a fastening member 135 which is connected to the two supporting arms 131, is disposed at an end of the support member 13 away from the side stand 30, and is configured to be detachably connected with a clasp disposed on the mixing barrel 20. The fastening member 135 comprises a handle 136 pivotably connected to the two supporting arms 131 and a hook 137 connected to an end of the handle 136. The hook 137 may be a U-shaped metallic rod and is flexible. The hook 137 is configured to hook on the clasp of the mixing barrel 20, and is fastened or loosened by pivoting the handle 136. The support member 13 further comprises a transverse rod 133 supporting between the two supporting arms 131 and disposed between the side stand 30 and the fastening member 135 to increase the structural strength of the support member 13.

[0021] The lid device 10 further comprises a sealing member 115 connected to and surrounding a rim of the lid body 11. When the lid device 10 is closed, the sealing member 115 is tightly clamped between a barrel edge of the mixing barrel 20 and the lid body 11 to seal the mixing barrel 20. The sealing member 115 may be made of silicone.

[0022] A scraping device 50 is connected to the lid device 10 and comprises a rotating handle 51 and a scraper 53. The rotating handle 51 is disposed above the lid body 11 and is rotatable relative to the lid body 11. The scraper 53 is disposed below the lid body 11 and is connected to the rotating handle 51 to be driven to rotate relative to the lid body 11 to scrape the food ingredients attached to a bottom of the lid body 11 or an internal peripheral surface of the mixing barrel 20.

[0023] With reference to FIGS. 3 to 5, the lid body 11 and the support member 13 are connected by the linking members 15 and each linking member 15 is pivotable relative to the holder 12 and is pivotable relative to the support member 13. When the lid device 10 pivots downwardly relative to the side stand 30 around a pivot shaft disposed between the support member 13 and the side stand 30, the lid body 11 is subjected to gravity to swing relative to the support member 13. As a result, the lid body 11 contacts the barrel edge of the mixing barrel 20 almost horizontally. The lid device 10 is subjected to a uniform force during closing, thereby enhancing the closing tightness of the lid device 10.
