Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a shell structure of a cup washing machine. Background Art

[0002] Appliances used on the market to clean single-sided open cups such as teacups, water cups, teapots, kettles, and milk tea cups are called teacup washers or cup washers. Traditional teacup washers only spray water or soak in a water bath, which doesn't effectively clean tea residue at the bottom of the cup, resulting in mediocre cleaning results. However, with technological advancements, washers have emerged in recent years that can better clean cups by placing the cups upside down. For example, Chinese invention patent application No. 202211462345.X discloses a teacup washer that sprays water from a nozzle below to clean the cups, achieving excellent cleaning results. However, a drawback of this machine is that the cleaning trough, which temporarily stores water and tea residue, is not removable. Over time, tea leaves and tea residue fall into the trough during the cleaning process, and the amount accumulates. Users can only remove the tea residue manually, unable to remove the trough separately for cleaning, which is very inconvenient. Furthermore, the positioning structure and cup holder design within the trough are not optimal, making assembly and use difficult. Therefore, improvements are necessary. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 3 As shown, a shell structure of a cup washing machine includes an outer shell 1 and a quick-release box 2. A positioning step 3 is provided on the side of the upper side 1 of the outer shell. The quick-release box 2 is provided with a positioning flange 4 corresponding to the position of the positioning step 3. A positioning boss 5 is provided in the outer shell 1. The quick-release box 2 is provided with a positioning hole 6 corresponding to the position of the positioning boss 5. When the quick-release box 2 is installed to the outer shell 1, the positioning boss 5 is inserted into the positioning hole 6 and the positioning flange 4 is mounted on the positioning step 3. When disassembling, it is very convenient to lift the quick-release box 2 and separate the outer shell 1. A sealing ring can be used between the positioning hole 6 and the positioning boss 5 to prevent water leakage. A cup rack 7 is installed in the quick-release box 2. The cup rack 7 is used to place single-opening cups such as tea cups, water cups, teapots, kettles, milk tea cups, bean juice cups, fruit cups, etc. A nozzle shaft 8 is installed in the positioning boss 5, and the nozzle shaft 8 extends into the quick-release box 2. A nozzle 9 is installed above the nozzle shaft 8.

[0024] Specifically, the positioning step 3 is arranged around the inner side of the shell 1 to improve the bearing capacity, and the outer side and upper part of the positioning step 3 form a shell limiting edge 10, and the outer side and upper part of the positioning flange 4 form a box limiting edge 11. The box limiting edge 11 is close to the shell limiting edge 10, and the setting of the limiting edge is convenient for taking and placing.

[0025] like Figure 2 and 4 As shown, a fixed block 12 is provided at the rear of the shell, and the fixed block 12 is connected to the hinge block 13 through a pivot.
