Description

Technical Field

[0001] The utility model belongs to the field of disinfection and cleaning machines, Background Art

[0002] The structure of the disinfection and cleaning machine is similar to that of a household drum washing machine, including a housing with an opening at the front side. A door panel that can be rotated horizontally to open is provided at the opening of the housing. A hinge connected to the housing is provided on one side of the door panel, a locking hook connected to the housing is provided on the other side of the door panel, and an observation window made of glass is provided in the middle of the door panel. The observation window is recessed inward and cooperates with the sealing ring on the housing to prevent leakage at the same time.

[0003] The main difference between the disinfection and cleaning machine and the drum washing machine is commercial use, and it is more bulky. When the door panel is opened, a large area needs to be passed through. When there are obstacles in this area, the opening angle of the door panel will be too small, making it impossible to smoothly pick up and place clothes. Therefore, if the opening direction of the door panel can be changed, it may be possible to avoid obstacles and make the placement of the disinfection and cleaning machine more flexible.

[0004] The door panel on the existing disinfection and cleaning machine has a fixed opening direction, while there is a structure on the drum washing machine that can install the door panel in a reversed direction. For example, the two-way door of the drum washing machine with the publication number CN2557554Y can be set to be hinged on the left and opened on the right, or set to be hinged on the right and opened on the left. The above two-way door can be applied to the disinfection and cleaning machine, but there is still a problem, that is, in the above two-way door, the observation window is frustum-shaped, which is different from the structure of the observation window on the disinfection and cleaning machine. The inner end of the observation window on the disinfection and cleaning machine also has an inclined surface, which can improve the washing effect. Normally, the inclined surface should face upward to form sufficient space for clothes to fall and be beaten. However, after the two-way door is reversed, the inclined surface will face downward, not only unable to improve the washing effect, but also seriously reducing the washing effect. Therefore, if the two-way door of the drum washing machine is applied to the disinfection and cleaning machine, further improvement is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a structure for reversing the installation of the door panel of a disinfection and cleaning machine. The utility model has the advantages of being able to reverse the opening of the door panel and not reducing the washing effect of the disinfection and cleaning machine

[0006] The technical solution of the utility model: The structure for reversing the installation of the door panel of a disinfection and cleaning machine includes an annular mounting plate. A door panel is provided on the axial side of the mounting plate. A lock connecting the door panel is provided on one radial side of the mounting plate. A hinge connecting the door panel is provided on the other radial side of the mounting plate. An observation hole is provided in the middle of the door panel. A frustum-shaped observation window is provided at the observation hole. The small end of the observation window passes through the mounting plate and is provided with an inclined surface. The observation window is detachably connected to the door panel.

[0007] In the aforementioned structure for reversibly installing the door panel of the disinfection and cleaning machine, the large end of the observation window is recessed inward, so that the observation window forms a structure with a uniform wall thickness. The outer edge of the observation window extends radially outward to form a mounting edge, and the mounting edge is detachably connected to the inner wall of the door panel. A transparent cover plate fixed to the door panel is provided on the inner side of the mounting edge.

[0008] In the aforementioned structure for reversibly installing the door panel of the disinfection and cleaning machine, a plurality of first mounting holes are provided on the mounting edge. Mounting posts fixed to the door panel are provided in the first mounting holes. A pressure sleeve is provided on the outer side of the mounting posts, and a screw for pressing the pressure sleeve against the mounting edge is provided at the end of the mounting posts.

[0009] In the aforementioned structure for reversibly installing the door panel of the disinfection and cleaning machine, a gap is formed between the pressure sleeve and the door panel. A pressure ring for pressing the mounting edge is provided on the outer peripheral surface of the pressure sleeve, and the material of the pressure sleeve is nylon.

[0010] In the aforementioned structure for reversibly installing the door panel of the disinfection and cleaning machine, mounting portions extend outward from both radial sides of the mounting plate. The two mounting portions are symmetrically distributed about the axis of the mounting plate, and the hinge and the lock are respectively located on the two mounting portions.

[0011] In the aforementioned structure for reversibly installing the door panel of the disinfection and cleaning machine, a plurality of second mounting holes are provided on the mounting plate.

[0012] Compared with the prior art, the present utility model applies the two-way door of the drum washing machine to the disinfection and cleaning machine, enabling the door panel to be reversibly installed and reversibly opened. On this basis, the connection structure between the observation window and the door panel is improved, and the observation window is set to be detachably connected. When the door panel is reversed and the inclined surface on the observation window faces downward, by removing the observation window, rotating it 180° and then reinstalling it, the inclined surface can be restored to face downward, avoiding the reduction of the washing effect. Therefore, the present utility model has the advantages of being able to reversibly open the door panel and not reducing the washing effect of the disinfection and cleaning machine.

[0013] In addition, mounting posts passing through the observation window are provided on the door panel, increasing the bonding length between the screw and the door panel, enabling the observation window to be better fastened. At the same time, the mounting posts play a positioning role, making the installation position of the observation window accurate and enabling good cooperation with the sealing ring on the housing of the disinfection and cleaning machine, thereby better preventing water inside the machine from leaking outwards. In order to prevent the edge of the mounting hole on the observation window from cutting the mounting posts, a pressure sleeve made of a high-strength material is provided on the outer side of the mounting posts. The pressure sleeve not only enables the pressure of the screw to be transmitted to the observation window, but also protects the mounting posts and extends their service life.
