[0057] Figure 2 It is a schematic diagram of the partial structure of the inner liner 2 provided in the present application. Figure 3 yes Figure 2 Schematic cross-sectional view of the blower 4 and the light source 3. Figure 4 yes Figure 3 A partial schematic diagram of the middle protective cover 5. Figure 5 Schematic diagram of the structure of the protective cover 5 provided in the embodiment of the present application. Figures 2 to 5 As shown, the cleaning machine further includes a protective cover 5, and the fan 4, heater 6 and light source 3 are all installed on the rear wall plate 21 of the cleaning chamber. The protective cover 5 is arranged outside the fan 4, heater 6 and light source 3 to prevent the user from directly touching the fan 4 and light source 3. The protective cover 5 has a panel 54, and a light-transmitting hole 541 is opened on the panel 54. The protective cover 5 is assembled on the rear wall plate 21 of the cleaning chamber and covers the light source 3. In addition, the protective cover 5 is provided with an opening 511 at a position opposite to the light source 3. The panel 54 is constrained at the opening 511 and is arranged to be rotatable relative to the light source 3 to change the position of the light-transmitting hole 541 relative to the light source 3, expand the irradiation range of the light source 3, allow more tableware to receive light irradiation, and improve the disinfection efficiency of the tableware.

[0058] The protective cover 5 is mounted on the rear wall plate 21 of the cleaning chamber, and defines a first chamber 510 and a second chamber 520 that are independent of each other. The light source 3 is located in the first chamber 510, and the fan 4 and the heater 6 are located in the second chamber 520. The protective cover 5 is provided with an air guide port 521 connecting the cleaning chamber and the second chamber 520 at a corresponding position. The panel 54 has a wind shield located on the air outlet path of the air guide port 521. The airflow generated by the fan 4 can be blown from the air guide port 521 to the wind shield of the panel 54, so that the panel 54 rotates relative to the light source 3. When the fan 4 is working, the airflow generated by the fan 4 can be blown out from the air guide port 521 and blown to the wind shield on the panel 54, so that the panel 54 rotates relative to the light source 3, thereby changing the position of the light transmission hole 541 on the panel 54 relative to the light source 3, expanding the irradiation range of the light source 3, allowing more tableware to receive light irradiation, and improving the disinfection efficiency of the tableware.

[0059] The fan 4 and the light source 3 are distributed on the left and right sides of the rear wall plate 21. The protective cover 5 extends horizontally, and has a first cover body 51 and a second cover body 52 at both ends of the extension direction. The first cover body 51 and the second cover body 52 are spaced apart from the rear wall plate 21 to define and form a first chamber 510 and a second chamber 520 accordingly. An opening 511 is provided on the first cover body 51, and the panel 54 is rotatably mounted on the opening 511. An air guide port 521 is provided on the second cover body 52, and the second cover body 52 also has an air inlet 524. When the fan 4 is working, the air in the cleaning chamber enters the second chamber 520 from the air inlet 524, and then blows out from the air guide port 521 to the windshield of the panel 54, so that the panel 54 rotates relative to the first cover body 51.

[0060] The protective cover 5 also has a partition area 53 between the first cover body 51 and the second cover body 52. ​​The partition area 53 extends along the width direction of the protective cover 5, that is, the partition area 53 extends along the vertical direction, so that the first chamber 510 and the second chamber 520 are arranged on the left and right and are independent of each other. The second chamber 520 is independently arranged relative to the first chamber 510, which can ensure that when the fan 4 is working, the airflow can enter from the air inlet 524 of the second cover body 52 and blow out from the air guide port 521, ensuring that the panel 54 can rotate under the action of the airflow generated by the fan 4.

[0061] The partition area 53 is a groove formed by being recessed backward from the front end surface of the protective cover 5, so that the first chamber 510 formed between the first cover body 51 and the rear wall plate 21 and the second chamber 520 formed between the second cover body 52 and the rear wall plate 21 are independent of each other. In this embodiment, the spray arm water supply pipe 100 of the water supply mechanism is installed on the rear wall plate 21 of the cleaning chamber, and the partition area 53 cooperates with the spray arm water supply pipe 100, so that the first chamber 510 formed by the first cover body 51 and the rear wall plate 21 and the second chamber 520 formed by the second cover body 52 and the rear wall plate 21 are independent of each other. Further, the periphery of the first cover body 51 has a first fixed edge 512, and the first fixed edge 512 is fixedly connected to the rear wall plate 21 of the cleaning chamber; the periphery of the second cover body 52 has a second fixed edge 522, and the second fixed edge 522 is fixedly connected to the rear wall plate 21 of the cleaning chamber.

[0062] Of course, in other embodiments, when the fan 4, the heater 6 and the light source 3 are installed on the left wall plate 22 of the cleaning chamber, the protective cover 5 is also installed on the left wall plate 22 of the cleaning chamber. In this case, the partition area 53 can directly cooperate with the left wall plate 22 to make the first chamber 510 and the second chamber 520 independent of each other. In other embodiments, when the fan 4, the heater 6 and the light source 3 are installed on the right wall plate 23 of the cleaning chamber, the protective cover 5 is also installed on the right wall plate 23 of the cleaning chamber. In this case, the partition area 53 can directly cooperate with the right wall plate 23 to make the first chamber 510 and the second chamber 520 independent of each other.

[0063] The air guide port 521 is provided on the second cover body 52 and is located on the first side wall 523 adjacent to the second cover body 42 and the first cover body 51 and opposite to the wind shield, so that the airflow blown out of the air guide port 521 can be smoothly blown to the wind shield. In addition, the wind shield is a baffle 542 extending from the panel 54 axially toward the outside of the first chamber 510, so as to ensure that the airflow blown out of the air guide port 521 can be blown to the side wall of the baffle 542, thereby ensuring that the panel 54 rotates by the airflow blowing against the baffle 542.

[0064] In this embodiment, the first side wall 523 is arranged to tilt forward from the partition area 53 to the direction away from the opening 511 of the first cover body 51, so that the opening direction of the air guide port 521 is opposite to the wind shield. The first cover body 51 has a second side wall 513 adjacent to the second cover body 52, and the second side wall 513 is arranged to tilt forward from the partition area 53 to the direction of the opening 511 to form an air guide surface, the air inlet end of the air guide surface is in fluid communication with the air guide port 521, and the air outlet end of the air guide surface is in fluid communication with the wind shield, so as to ensure that the airflow blown out from the air guide port 521 can be blown smoothly to the wind shield.

[0065] Continue to see Figure 3 to Figure 4 As shown, the distance between the front end of the second side wall 513 and the bottom wall of the groove formed by the partition area 53 is smaller than the distance between the front end of the first side wall 523 and the bottom wall of the groove, so as to ensure that the airflow blown out of the air guide port 521 on the first side wall 523 can be smoothly blown onto the baffle 542 of the panel 54. The difference between the distance between the front end of the first side wall 523 and the bottom wall of the groove and the distance between the front end of the second side wall 513 and the bottom wall of the groove formed by the partition area 53 is d, and the value range of d can be designed according to the distance between the baffle 542 and the front end surface of the first cover body 51, and is not limited here.

[0066] In one embodiment, the slope of the second side wall 513 is not greater than the slope of the first side wall 523 . This configuration allows the airflow blown out of the air guide port 521 to flow along the air guide surface formed by the second side wall 513 to the baffle 542 of the panel 54 .

[0067] The second cover 52 also has an air outlet 525, which is opened on the upper side wall, the lower side wall and the left side wall of the second cover 52. When the fan 4 and the heater 6 are working, the hot air blown out from the air outlet 525 can dry the dishes. Of course, the air guide 521 can also be used as the air outlet 525 to provide drying hot air for the washing chamber, but the airflow blown out from the air guide 521 is mainly used as the power source for the rotation of the panel 54.

[0068] Figure 6 is a cross-sectional schematic diagram of the first cover body 51 provided in the embodiment of the present application. Figure 6As shown, the inner edge of the opening 511 has a circumferentially extending limiting groove 5111, and the periphery of the panel 54 is rotatably constrained in the limiting groove 5111. In one embodiment, the front wall of the limiting groove 5111 is a continuously arranged circular ring, and the rear wall of the limiting groove 5111 is a discontinuously arranged limiting protrusion, which facilitates the assembly between the panel 54 and the opening 511 of the first cover body 51 while realizing the limiting constraint of the panel 54. In another embodiment, the rear wall of the limiting groove 5111 is a continuously arranged circular ring, and the front wall of the limiting groove 5111 is a discontinuously arranged limiting protrusion, which facilitates the assembly between the panel 54 and the opening 511 of the first cover body 51 while realizing the limiting constraint of the panel 54. In another embodiment, the front wall and the rear wall of the limiting groove 5111 are both continuously arranged circular rings, and this scheme can also realize the limiting installation of the panel 54.

[0069] Figure 7 It is a structural schematic diagram of a panel 54 provided in an embodiment of the present application from one viewing angle. Figure 8 FIG. 5 is a schematic diagram of the structure of the panel 54 provided in another perspective of the embodiment of the present application. Figures 7 and 8 Combined with Figure 5 As shown, there are at least two light-transmitting holes 541, and they are arranged at intervals in the circumferential direction of the panel 54. By reasonably arranging the light-transmitting holes 541, the number of light-transmitting holes 541 can be increased, thereby increasing the irradiation range of the light source 3 and improving the disinfection efficiency of the light source 3. The light-transmitting holes 541 are bar-shaped holes, and each light-transmitting hole 541 has an arc structure with both ends bent toward the same side, and each light-transmitting hole 541 on the panel 54 is arranged in the same bending direction as a whole. The arrangement of the light-transmitting holes 541 can not only facilitate the passage of light, but also prevent users from touching the light source 3, thereby improving the safety of the product.

[0070] In this embodiment, at least two light-transmitting holes 541 form a light-transmitting hole group, and three light-transmitting hole groups are arranged on the panel 54, each light-transmitting hole group has five light-transmitting holes 541, and the extension directions of two adjacent light-transmitting hole groups intersect. In another embodiment, any number of light-transmitting hole groups, such as one group, two groups, four groups, five groups, six groups, or seven groups, can be arranged on the panel 54, and the specific design can be based on the size and arrangement of the light-transmitting holes 541 and the size of the panel 54, which is not limited here.

[0071] At least two of the light-transmitting holes 541 in each light-transmitting hole group have baffles 542 at any side in the length direction thereof, and each baffle 542 has the same bending posture as the corresponding light-transmitting hole 541. That is, the baffles 542 are in the shape of long strips, and both ends of the baffles 542 are bent toward the same side, so that the baffles 542 have a wind-gathering effect, which can increase the impact force of the airflow on the baffles 542, and ensure that the airflow can blow the panel 54 to rotate smoothly.

[0072] In this embodiment, one side of all the light-transmitting holes 541 in one of the three light-transmitting hole groups has a baffle 542. In another embodiment, some of the light-transmitting holes 541 in one of the light-transmitting hole groups may have a baffle 542, which will not be described one by one here.

[0073] In one embodiment, a reflective coating may be coated on the side wall of the baffle 542 facing the light-transmitting hole 541 , which may also expand the disinfection range of the light source 3 to a certain extent, thereby improving the disinfection efficiency.

[0074] It should be noted that the arrangement of the air inlet 524 on the second cover body 52 is basically the same as the arrangement of the light-transmitting holes 541 of the panel 54, except that the bending direction of the air inlet 524 is opposite to the bending direction of the light-transmitting holes 541. The shape and arrangement of the air inlet 524 of the second cover body 52 will not be described in detail here.

[0075] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
