Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a cover of a cleaning and disinfecting machine and a household cleaning and disinfecting machine. Background Art

[0002] When the cover of an existing household cleaning and disinfecting machine is closed, the cleaning chamber forms a completely sealed space. This results in a pressure difference between the internal and external pressures of the cleaning chamber, which affects the normal operation of the high-pressure water flow. In order to balance the pressure inside and outside the cleaning chamber, a breathing hole is usually opened in the cover.

[0003] However, although this method solves the problem of pressure imbalance inside and outside the cleaning chamber, it will cause the high-pressure water flow sprayed from the cleaning chamber to splash to the outside through the breathing hole when the cleaning and disinfecting machine is working, affecting the user experience. Utility Model Content

[0004] The utility model provides a cover of a cleaning and disinfecting machine and a household cleaning and disinfecting machine, aiming to solve the problem in the prior art that high-pressure water flow in the cleaning and disinfecting machine may splash to the outside through the breathing hole.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] In the first aspect, the utility model provides a cover for a cleaning and disinfecting machine, comprising a cover body; a handle portion is provided on the upper surface of the cover body; a transition portion is provided between the handle portion and the cover body; a ventilation channel is provided near the transition portion, and the ventilation channel is inclined from bottom to top toward the handle portion.

[0007] A further solution: the outer port of the ventilation channel is arranged along the transition portion.

[0008] A further solution: the outer port of the ventilation channel is an arc-shaped hole.

[0009] Based on the above solution, the configuration structure of the outer port of the ventilation channel can maximize the amount of gas passing through the ventilation channel and accelerate the air circulation inside the cover.

[0010] A further solution: the cover body includes a top plate; the handle portion is located on the upper surface of the top plate; a guide plate is provided below the top plate;

[0011] The ventilation channel includes a first channel section and a second channel section that are interconnected; the first channel section is arranged on the top plate; and the second channel section is located between the top plate and the guide plate.

[0012] Based on the above solution, the first channel section and the second channel section can communicate with the inside and outside of the cover body, making it convenient to balance the pressure inside and outside the cover body through the ventilation channel.

[0013] A further solution: the guide plate includes a connecting end and a guide surface; the guide plate is connected to the bottom of the top plate through the connecting end; the guide surface is gradually arranged downward from a side close to the connecting end to a side away from the connecting end.

[0014] Based on the above solution, the guide surface is gradually tilted downward from the side closest to the connection end to the side farther from the connection end. On the one hand, this prevents the path of the ventilation channel from being perpendicular to the cover, thereby preventing the high-pressure water flow inside the cover from splashing out through the ventilation channel. On the other hand, even if water splashes into the ventilation channel, the downward tilt of the guide surface allows the water adhering to the guide surface to flow back into the interior of the cover.

[0015] A further solution: a first vent is provided above the first channel section; a second vent is provided below the second channel section;

[0016] The first vent is located on the surface of the top plate and close to the transition portion; the second vent is located below the top plate and away from the transition portion.

[0017] A further solution: a buffer space is provided between the connecting end and the first channel section.

[0018] Based on the above solution, the buffer space allows water entering the ventilation channel to enter the buffer space before passing through the first channel section, and then be blocked by the buffer space, preventing the water from passing through the first channel section and thus preventing the water from splashing to the outside of the cover body.

[0019] A further solution is that an arc-shaped water baffle is provided inside the cover body and near the inner end of the ventilation channel.

[0020] Based on the above solution, the water baffle is arranged near the second vent, and can prevent water splashes inside the cover from entering the second vent.

[0021] A further solution: a recessed portion is provided on the upper surface of the cover; the handle portion is composed of an arc-shaped handle plate and the recessed portion; the opening of the handle portion is arranged to face forward;

[0022] The transition portion is arranged at the edge of the handle plate, and the handle plate is connected to the rear side of the recessed portion through the transition portion, and a space for inserting a hand is provided between the handle plate and the recessed portion.

[0023] Based on the above solution, the handle portion formed by the handle plate and the recessed portion makes it convenient for the user to take the cover.

[0024] In the second aspect, the utility model provides a household cleaning and disinfecting machine, comprising a base and a cover of a cleaning and disinfecting machine as described in any one of the first aspects, which is arranged on the base; when the cover is arranged on the base, a cleaning cavity is provided between the base and the cover.

[0025] The beneficial effects of the utility model are:

[0026] The utility model is provided with a ventilation channel from bottom to top. The path of the ventilation channel is not perpendicular to the cover body like the breathing hole in the prior art, but is arranged at an angle. This structure can not only connect the inside and outside of the cleaning chamber and balance the internal and external pressures of the cleaning chamber; but also effectively prevent the high-pressure water flow sprayed from the cleaning chamber from splashing to the outside through the ventilation channel.

[0027] Since the ventilation channel is arranged to be inclined from bottom to top, even if a small amount of water splashes into the ventilation channel, the water droplets will flow back into the cleaning chamber along the inner wall of the ventilation channel.

[0028] In addition, even if a small amount of water splashes out through the ventilation channel, since the ventilation channel is directed toward the handle portion, the handle portion will block the sprayed water, causing the splashed water to flow back into the ventilation channel along the surface of the handle portion, thereby preventing water from splashing onto the user or other places.

[0044] In addition to the above-mentioned solution, the structure of the handle portion may also be other structures, as long as the ventilation channel 2 is inclined from bottom to top toward the handle portion.

[0045] A more specific example of the ventilation channel 2 is: Figure 1 As shown, the outer port of the ventilation channel 2 is arranged along the transition portion 14; the outer port of the ventilation channel 2 is an arc-shaped hole.

[0046] The cover body 1 includes a top plate 11; the handle portion is located on the upper surface of the top plate 11; a guide plate 21 is provided below the top plate 11;

[0047] The ventilation channel 2 includes a first channel section and a second channel section that are interconnected; the first channel section is disposed on the top plate 11 ; and the second channel section is located between the top plate 11 and the guide plate 21 .

[0048] Specifically, the channel path of the first channel section is perpendicular to the top plate 11 ; the channel path of the second channel section is inclined relative to the top plate 11 .

[0049] like Figure 4 As shown, it should be noted that: in order to ensure the stability of the guide plate 21, a support plate 211 is provided between the middle position of the guide plate 21 and the top plate 11 to support the guide plate 21 and improve the installation stability of the guide plate 21.

[0050] In order to realize the inclined setting of the ventilation channel 2, the following scheme is adopted for the structure of the guide plate 21: the guide plate 21 includes a connecting end and a guide surface; the guide plate 21 is connected to the bottom of the top plate 11 through the connecting end; the guide surface is gradually set downward from the side close to the connecting end to the side away from the connecting end.

[0051] like Figure 3 As shown, a first vent 22 is provided above the first channel section; a second vent 23 is provided below the second channel section;
