Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 12, a tableware disinfection cabinet comprises a disinfection inner container 1 with an open front side, a heating device 6 is disposed at the bottom of the disinfection inner container 1, and the heating device 6 is an electric heating tube in this embodiment. An upper drawer 11 and a lower drawer 12 are arranged in the disinfection liner 1 from top to bottom, and the bottom parts of the upper and lower drawers 11,12 are respectively provided with a flow guide layer 2 in the embodiment. Each flow guiding layer 2 has a first flow guiding arc surface 211, a flow guiding gap 22 and a flow guiding impeller 3. The first flow guiding arc surfaces 211 are located on the bottom surface of the flow guiding layer 2 and protrude downward, at least two first flow guiding arc surfaces 211 are arranged in parallel, the flow guiding gaps 22 are located between two adjacent first flow guiding arc surfaces 211, and the flow guiding impeller 3 is arranged above the flow guiding gaps 22 and can rotate under the action of air flow. In this embodiment, since the upper and lower drawers 11,12 have the same structure and both include the drawer frame 101 and the drawer basket 102 disposed in the drawer frame 101, fig. 5, 9 and 11 only illustrate the structure of the upper drawer 11.
The heating device 6 is arranged at the bottom of the disinfection liner 1, so that the bottom wall of the disinfection liner 1 can be heated through the action of heat radiation, and the bottom wall of the disinfection liner 1 after being heated heats the air at the bottom of the disinfection liner 1 in a heat transfer mode. According to the chimney effect, air density difference is generated due to temperature difference, so that pressure difference is formed, and then the air flows from bottom to top under the action of the pressure difference. Therefore, the heating device 6 heats the air at the bottom in the inner container 1, the generated hot air rises due to pressure difference, and a hot flow field from bottom to top is formed in the disinfection inner container 1. In the rising process of hot air, the hot air rises upwards through the first flow guide arc-shaped surfaces 211 facing the bulges, the first flow guide arc-shaped surfaces 211 on the two sides guide the hot air to the flow guide gap 22 between the hot air and the flow guide impellers 3, the hot air rising from bottom to top drives the flow guide impellers 3 to rotate, and the rotation of the flow guide impellers 3 can generate a certain wind field, so that the drying of tableware is promoted, negative pressure is formed in the flow guide gap 22, and the hot air is promoted to rise upwards through the first flow guide arc-shaped surfaces 211 on the two sides and the flow guide gap 22 from bottom to top in sequence. Therefore, the flow guide layer 2 can promote the rising of hot air to fully spread around the tableware of each drawer, so that the temperature fields around the tableware are uniform, the hot air is uniformly distributed in the disinfection liner 1, the drying speed of the tableware is increased, and the disinfection effect is improved.

The outer surfaces of the adjacent blades 31 of the guide vane wheel 3 form smooth second guide arc surfaces 32, and in the rotation process of the guide vane wheel 3, the outer edges of the blades 31 of the guide vane wheel 3 along the axial direction thereof are located above the water collection tank 210, and the vertical projection of the outer edges in the water collection tank 210 is located inside the water collection tank 210. Thus, the water drops on the tableware can be directly dropped into the water collecting tank 210 to be collected, or can be dropped onto the second guiding arc surface 32 of the guiding impeller 3 (for example, in the first state, the water drops are collected in the second guiding arc surface 32 on the upper portion of the guiding impeller 3, as shown in fig. 9 and 10), and the water drops dropped onto the second guiding arc surface 32 are dropped into the water collecting tank 210 along with the rotation of the guiding impeller 3 (in the second state, the water drops are thrown into the water collecting tank 210 when the guiding impeller 3 rotates from the first state to the second state, as shown in fig. 11 and 12). Thereby can avoid on 11 middle tableware of upper drawer water droplet to drop to on the drawer 12 and upper and lower drawer 11,12 on the water droplet drips to the internal surface of disinfection inner bag 1 to promote user's use and experience. In addition, in the rotation process of the guide vane wheel 3, the second guide arc surface 32 on the guide vane wheel can throw hot air transferred to the guide vane wheel into the water collecting tank 210, so that the hot air can enter the water collecting tank 210 and rise upwards, and meanwhile, the hot air thrown into the water collecting tank 210 can play a certain drying role on water collected in the water collecting tank 210.
Each flow guiding layer 2 can have a plurality of specific implementation manners, in this embodiment, each flow guiding layer 2 includes a water collection cover 21, each water collection cover 21 extends in the left-right direction of the corresponding drawer, and meanwhile, the water collection covers 21 in each flow guiding layer 2 are respectively arranged at intervals in the front-back direction of the corresponding drawer. Correspondingly, each of the above-mentioned guide vanes 3 also extends along the left-right direction of the drawer, and the guide vanes 3 of each guide layer 2 are also respectively arranged along the front-back direction of the corresponding drawer at intervals, i.e. each water collection cover 21 and each guide vane 3 are arranged at intervals in the front-back direction and are staggered up and down. The cross section of each water collecting cover 21 is arc-shaped and the two ends are closed, the inner cavity of each water collecting cover 21 forms the water collecting groove 210, and the bottom surface of each water collecting cover 21 forms the first air guiding arc surface 211. In this embodiment, each water collection cover 21 has a semicircular cross section.
Further, in this embodiment, each guide vane wheel 3 includes a central hole 30 located at the center and the fan blades 31 circumferentially spaced from the central hole 30, each fan blade 31 is square, an included angle formed by adjacent fan blades 31 in each guide vane wheel 3 is 90 °, and a connection between adjacent fan blades 31 is in smooth transition. The guide vane wheel 3 has two ends of the central hole 30 inserted with connecting shafts 4, and the free ends of the connecting shafts 4 are fixed to the bottom of the corresponding drawer, so that the guide vane wheel 3 can rotate around the central shaft with the connecting shafts 4 at the two ends as the fulcrum. In addition, the above-mentioned structure design of the guide vane wheel 3 enables it to rotate better under the action of the hot air flow from bottom to top, and at the same time, can guide the water drops dropping on it into the water collecting tank 210 more smoothly.
In this embodiment, in order to make each guide layer 2 be installed in the bottom that corresponds the drawer firmly, still include the mounting bracket 5 that is used for being connected each water collecting cover 21 and the drawer bottom that corresponds, this mounting bracket 5 sets up respectively at the both ends of each guide layer 2, and each mounting bracket 5 all includes along the installation horizontal pole 51 that extends with each water collecting cover 21 extending direction looks vertically, all be equipped with the spliced pole 52 with each guide layer 2 water collecting cover 21 one-to-one along its length direction interval on this installation horizontal pole 51, and each spliced pole 52 is fixed with corresponding water catch bowl 210 respectively, still be fixed with the equipment post 53 on the installation horizontal pole 51, this equipment post 53 is fixed with the bottom that corresponds the drawer.
