Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a steam cleaning robot. Background Art

[0002] Currently, cleaning robots (such as window cleaning robots) commonly use atomizers to wet glass surfaces. These atomizers use piezoelectric ceramic materials to generate high-frequency vibrations under the influence of an alternating voltage, dispersing water into fine droplets and creating an atomized effect, thereby wetting the glass surface. However, existing atomizer technology has limitations. One notable issue is that the atomizers themselves lack a heating function and can only produce a mist at room or low temperatures. This mist is limited in its effectiveness at softening and removing some stubborn stains, as these stains often require higher-temperature water vapor to effectively dissolve. Utility Model Content

[0057] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0058] like Figure 1-14 As shown, this embodiment provides a cleaning robot, which includes a body 1, on which is disposed a cleaning portion for performing a cleaning function, such as a cleaning turntable or a cleaning cloth 4, and a walking portion for driving the robot, such as a crawler structure 8 or walking wheels, at the bottom of the body 1. Since the walking mechanism and control principle of the cleaning robot of this embodiment are similar to those of existing cleaning robots, they will not be described in detail here.

[0059] Different from the existing cleaning robots, this embodiment no longer uses an atomizing sheet to wet the surface to be cleaned, but instead uses a steam device 2 to achieve this. Specifically, Figure 4-6As shown, a steam device 2 is provided on the body 1, which is connected to a water tank 3 that supplies water thereto. The steam device 2 has a heating function, capable of heating the water output from the water tank 3 to a steam state and discharging the steam (water vapor) toward the surface to be cleaned (e.g., a glass surface), thereby moistening the surface. Compared to the normal temperature or low temperature water mist produced by the atomizing plate, the water vapor generated by the steam device 2 in this embodiment is at a higher temperature, which can quickly soften stubborn stains on the surface to be cleaned, significantly reducing the difficulty of cleaning. Furthermore, the higher temperature water vapor also has a certain disinfecting effect, helping to eliminate bacteria and viruses, providing a more hygienic cleaning effect. Furthermore, because the cleaning robot utilizes the water vapor generated by the steam device 2 to achieve a moistening effect, this embodiment is referred to as a steam-type cleaning robot.

[0060] The steam device 2 of this embodiment is not limited to cleaning robots equipped with a specific cleaning unit; it is applicable to any cleaning robot that needs to moisten a target object, such as a surface to be cleaned or a cleaning rag. For example, a cleaning robot equipped with a cleaning turntable can have the steam device 2 installed on the body 1, where the steam generated by the steam device 2 is used to moisten the surface to be cleaned. A cleaning robot equipped with a cleaning rag 4 (fixed to the bottom of the robot) can also have the steam device 2 installed on the body 1, where the steam generated by the steam device 2 is used to moisten the surface to be cleaned, and the steam can also be used to moisten the cleaning rag 4 simultaneously. Of course, depending on the needs, the robot can wet only the surface to be cleaned, the cleaning rag 4, or both. This embodiment will be described primarily using the steam device 2 installed on a cleaning robot equipped with a cleaning rag 4.

[0061] In this embodiment, the steam device 2 comprises a heating device 2a and a steam exhaust box 2b. The heating device 2a primarily heats water to a steam state, while the steam exhaust box 2b primarily discharges the steam, discharging it toward the target object to be humidified (e.g., the surface to be cleaned, or the cleaning rag 4). The heating device 2a is connected to a water tank 3. Water from the water tank 3 flows through the heating device 2a, heating it to a steam state. The steam exhaust box 2b is also connected to the heating device 2a. Steam generated by the heating device 2a flows to the steam exhaust box 2b, which then discharges the steam toward the cleaning rag 4 and / or the surface to be cleaned.

[0062] Among them, Figure 7-10As shown, the heating device 2a includes a steam box 2a1 and an electric heater 2a2 disposed within the steam box 2a1. The electric heater 2a2 uses electrical energy to heat water to a boil, thereby generating steam. The electric heater 2a2 may be made of ceramic. The steam box 2a1 is connected to the water tank 3 and the exhaust box 2b via pipes. The electric heater 2a2 within the steam box 2a1 is capable of heating water flowing from the water tank 3 through the steam box 2a1, converting it into steam, which then flows to the exhaust box 2b. Of course, the heating device 2a includes but is not limited to the above-described structure; it may also be other devices capable of heating water to a steam state. Furthermore, the steam box 2a1 includes an inner shell 2a1a and an outer shell 2a1b. The inner shell 2a1a serves as a steam storage space and houses the electric heater 2a2, while the outer shell 2a1b serves as a fixed and protective insulation structure. The electric heater 2a2 is provided with a terminal 2a2b for connecting to a power source.

[0063] Furthermore, a connecting channel 2a2a can be provided inside the electric heating element 2a2, which passes through the left and right ends thereof. The inner end of the connecting channel 2a2a is connected to the interior of the steam box 2a1, and the outer end thereof is connected to the water tank 3 through the pipe interface 2a1c on the right side of the steam box 2a1 and the pipe on the pipe interface 2a1c. Figure 9 、 10 Alternatively, a connecting pipe (not shown) is in close contact with the outer surface of the electric heating element 2a2. The inner end of the connecting pipe communicates with the interior of the steam box 2a1, and the outer end thereof is connected to the water tank 3 or is connected to the water tank 3 via the pipe interface 2a1c on the right side of the steam box 2a1 and the pipe on the pipe interface 2a1c. When the water output from the water tank 3 flows through the connecting channel 2a2a or the connecting pipe at the electric heating element 2a2, it can be converted into a steam state under the heating effect of the electric heating element 2a2 and enter the interior of the steam box 2a1. In addition, the electric heating element 2a2 is arranged in the steam box 2a1, which not only heats the water flowing therethrough to form steam, but also plays a certain role in heat preservation for the internal space of the steam box 2a1 (mainly the inner shell 2a1a), preventing the steam inside from liquefying due to a decrease in temperature. Moreover, even if the water in the connecting channel 2a2a or the connecting pipe is not completely vaporized and flows into the inner shell 2a1a, the electric heating element 2a2 can still heat it, so that the water in the inner shell 2a1a maintains a high temperature, which can also have a moistening effect on the target object and ensure a certain softening effect of stains.

[0064] To ensure that the water in the water tank 3 is smoothly delivered to the appropriate location, this embodiment further includes a pumping device 5 (e.g., a water pump) between the water tank 3 and the heating device 2a. These devices are connected by a pipe (i.e., a pipeline). The pumping device 5 is used to extract water from the water tank 3 and deliver it to the heating device 2a, where it flows into the connecting channel 2a2a or connecting pipe. The heating element 2a2 in the steam box 2a1 heats the water in the connecting channel 2a2a or connecting pipe to a steam state, which then flows into the steam box 2a1. The water then flows through the pipe to the corresponding exhaust box 2b and is discharged onto the surface to be cleaned and / or the cleaning cloth 4.

[0065] The steam device 2 can be configured not only to discharge steam to the surface to be cleaned, but also to discharge steam to the cleaning rag 4, which is fixed to the bottom of the body 1. In this embodiment, the steam device 2 can discharge steam to the cleaning rag 4. The specific configuration is as follows: Figure 2 、 5 As shown in Figure 11, the body 1 is provided with a mounting hole 1a, which is located above the cleaning rag 4. The steam exhaust box 2b is installed in the mounting hole 1a. The bottom of the steam exhaust box 2b is provided with a steam exhaust groove 2b1 for exhausting steam. The steam exhaust groove 2b1 is provided with a connecting hole 2b1a, and the connecting hole 2b1a is connected to the steam box 2a1 through a pipe. The notch of the steam exhaust groove 2b1 faces the cleaning rag 4, so that the steam can be directly sprayed onto the cleaning rag 4 to wet it. The cleaning rag wetted by high-temperature steam can also quickly soften stubborn stains on the surface to be cleaned, reducing the difficulty of cleaning, and its high-temperature characteristics also give it a certain disinfection effect, which helps to eliminate bacteria and viruses and provide a more hygienic cleaning effect. Generally speaking, a group of steam exhaust boxes 2b are provided at the front and rear ends of the body 1, and these two steam exhaust boxes 2b are connected to the steam box 2a1 through two pipes. Furthermore, the configuration for enabling the steam device 2 to discharge steam toward the surface to be cleaned is similar to that described above. Simply position the notch of the steam exhaust slot 2b1 of the steam exhaust box 2b directly toward the surface to be cleaned. The steam exhaust box 2b can be mounted on the bottom or side of the machine body 1. Of course, to enable the steam device 2 to discharge steam toward both the surface to be cleaned and the cleaning cloth 4 simultaneously, multiple steam exhaust boxes 2b can be installed on the machine. These steam exhaust boxes 2b can be connected to the same steam box 2a1. The specific configuration can be selected as needed.

[0066] For existing cleaning robots (such as window cleaning robots), due to the design requirements of miniaturization, the size of the atomizer is usually small, which limits its spraying range, resulting in the wetted area being insufficient to cover a large glass surface, affecting the overall cleaning effect. Figure 2 、 11As shown, in order to expand the wetting range, this embodiment configures the steam exhaust groove 2b1 into a long strip shape, with a length no less than half the width of the cleaning rag 4 or the housing 1. By diffusing the steam, the wetted area of the surface to be cleaned can be expanded when the steam is sprayed toward the surface to be cleaned. Furthermore, when the steam is sprayed toward the cleaning rag 4, the wetted area on the cleaning rag 4 can be expanded, thereby covering a larger area of the surface to be cleaned and improving the cleaning effect. Furthermore, when using a dry cleaning rag 4 to directly wipe the surface to be cleaned, the greater friction will increase the wear and tear of the rag. In contrast, using a wet cleaning rag 4 can reduce friction, thereby effectively reducing the wear and tear of the rag.

[0067] In this embodiment, if Figure 1-6 and Figure 12-14 As shown, the bottom of the water tank 3 is transparent (of course, the entire water tank 3 can also be transparent), and the water tank 3 can directly pass through the bottom of the body 1 and be exposed to the outside. In this way, the remaining water in the water tank 3 can be seen from the bottom of the body 1 directly through the transparent bottom of the water tank 3. Alternatively, a transparent area is provided at the bottom of the body 1, and the transparent bottom of the water tank 3 is close to or embedded in the transparent area at the bottom of the body 1. In this way, the remaining water in the water tank 3 can be seen from the bottom of the body 1 directly through the transparent area at the bottom of the body 1 and the transparent bottom of the water tank 3. There are many ways to allow the water tank 3 to pass through the bottom of the body 1 and be exposed to the outside. For example, a penetrating installation port 1b is provided at the bottom of the body 1, and the bottom of the water tank 3 is installed in the installation port 1b. In this way, the installation port 1b forms a window for observing the water level, which can be seen in FIG. Figure 3 . Among them, the water tank 3 and the body 1 can be two independent components, or they can be connected as one. For example, the bottom of the water tank 3 is embedded in the transparent area at the bottom of the body 1 and connected thereto as a whole. Then, when the shape, size and position of the transparent area at the bottom of the water tank 3 and the bottom of the body 1 are the same, the transparent bottom of the water tank 3 is the transparent area at the bottom of the body 1. Through the above-mentioned arrangement, the user only needs to observe from the bottom of the body 1 to intuitively see the amount of water in the water tank 3 without using any electronic equipment or sensors, which makes it convenient for the user to understand the water level in time and replenish water. For example, when the cleaning robot is wiping the window glass, the user in the room can see the water level in the water tank 3 at the bottom of the machine through the glass in real time. This intuitive feedback can improve the user's experience. Moreover, by reducing the use of electronic components, not only can the equipment cost be reduced, but also the risk of system failure due to sensor failure can be reduced, thereby improving overall reliability.

[0068] The cleaning robot of this embodiment can be used not only to clean floors and floors, but also to clean window glass. Since the cleaning robot needs to adhere to the glass when cleaning windows, it is necessary to equip it with a suction module 7. Specifically, a negative pressure chamber 6 is provided within the body 1, extending to the bottom of the body 1. The bottom of the body 1 is provided with a plurality of through-holes connecting the negative pressure chamber 6 with the outside world. The suction module 7 is disposed within the negative pressure chamber 6 of the body 1 and generates negative pressure suction by extracting air from the negative pressure chamber 6, allowing the cleaning robot to adhere to the surface to be cleaned. The suction module 7 includes, but is not limited to, a negative pressure blower or vacuum pump. During operation, it generates heat. To dissipate the heat generated by the suction module 7, the water tank 3 can be positioned close to the negative pressure chamber 6. This allows the water in the water tank 3 to absorb some of the heat dissipated by the suction module 7, thereby dissipating the heat. In this way, the water tank 3 not only stores water for spraying but also dissipates heat, achieving multiple uses and enhancing practicality.

[0069] The water in the water tank 3 of this embodiment can absorb the heat generated by the suction module 7 during operation, mainly through the natural cooling characteristics of water, to achieve efficient water-cooling and heat dissipation effects, ensuring the stability and safety of the robot during long-term operation. Moreover, the water tank 3 can surround the negative pressure chamber 6. In this way, not only can the internal space of the machine body 1 be fully utilized, making the machine structure more compact and the overall appearance more miniaturized, but it can also absorb the heat generated by the suction module 7 in the negative pressure chamber 6 to a greater extent and over a larger area, further reducing the impact of heat on the internal components of the machine and extending the life of the machine.

[0070] Furthermore, the water tank 3 can also extend from the top of the negative pressure chamber 6 to the bottom of the negative pressure chamber 6, so that the top and bottom areas of the negative pressure chamber 6 are surrounded by the water tank 3 (which can also be understood as covering). In this way, the water tank 3 can cover the entire height of the negative pressure chamber 6, which helps to more evenly disperse and absorb the heat generated by the suction module 7 and avoid local overheating. This design also increases the contact area between the water tank 3 and the negative pressure chamber 6, which can more effectively transfer heat from the suction module 7 to the water in the water tank 3, accelerating the heat dissipation rate. Moreover, the vertical extension of the water tank 3 also provides additional structural support for the negative pressure chamber 6, enhancing the overall stability and durability.

[0071] In this embodiment, if Figure 12-14As shown, the bottom of the water tank 3 is a transparent bottom shell 3a, on which an annular housing 3b is mounted (they are typically sealed together). The cavity formed by the annular sidewall in the middle of the housing 3b serves as the negative pressure chamber, and a through hole is provided in the center of the bottom shell 3a. This further improves the heat dissipation effect and eliminates the need for a mounting shell that would otherwise serve as the negative pressure chamber 6. The suction module 7 can be directly mounted within the annular sidewall of the annular housing 3b, resulting in a more compact structure. To facilitate the installation of the suction module 7 within the negative pressure chamber 6, the housing 3b and bottom shell 3a can be configured as a detachable structure.

[0072] Among them, the bottom of the water tank 3 and the transparent area at the bottom of the machine can both be made of transparent materials such as acrylic or polycarbonate. Of course, the water tank 3 can also be made of transparent materials as a whole. Among them, the bottom of the water tank 3 is a transparent material, that is, the transparent bottom shell 3a is a transparent material, taking it as an example of acrylic material. Acrylic material has good transparency, allowing users to clearly observe the water level in the water tank 3, making it convenient to replenish water in time. Compared with traditional glass or other transparent materials, acrylic material is lighter, which helps to reduce the overall weight of the cleaning robot, and the cost of acrylic material is relatively low, which helps to reduce production costs. Moreover, acrylic material is easy to process and shape, and has high impact resistance and is not easy to break.

[0073] Among them, Figure 15 As shown, a blue light lamp 10 and / or a disinfection lamp 11 can be provided on the body 1 to improve the cleaning effect and increase the disinfection function. For example, a blue light lamp 10 and a disinfection lamp 11 are provided on both sides of the bottom of the body 1, and the blue light lamp 10 and the disinfection lamp 11 can be provided alternately and at intervals on each side. Among them, the blue light lamp 10 can be used for lighting, which can help the user see the working status of the cleaning robot (such as a window cleaning robot) more clearly, especially in a dimly lit environment, the blue light lamp 10 can provide a better visual effect, thereby monitoring whether the robot is working normally. The disinfection lamp 11 can be an ultraviolet disinfection lamp, such as a UVC+UVA ultraviolet disinfection lamp, which can be used to disinfect the surface to be cleaned (such as a glass surface).

[0074] In addition, the cleaning robot can be equipped not only with a steam device for spraying steam, but also with a spraying component 9 for spraying water, which can provide a variety of functional options to adapt to different application scenarios.

[0075] Specifically, if Figure 16-19 As shown, the housing 1 is provided with a spray assembly 9, typically located on a side of the housing 1, such as the front or rear side. The spray assembly 9 includes a water spray connector 9a, an inner housing 9b, and an outer housing 9c located at the outlet of the water spray connector 9a. The water inlet of the water spray connector 9a is connected to a water tank via a water supply line, and a drive pump (e.g., a water pump) is provided on the water supply line for pumping and draining water.

[0076] Among them, Figure 17 、 18 As shown, the front end of the inner cover 9b is provided with a notch 9b1 that can open and close. This notch 9b1 can be elongated, forming an opening and closing structure similar to a mouth. To ensure that the notch 9b1 at the front end of the inner cover 9b automatically opens and closes, opening when the inner cover 9b is filled with water and the water pressure increases, and closing when the inner cover 9b is depleted and the water pressure decreases, the front end of the inner cover 9b can be configured as an elastic portion. For example, the front end of the inner cover 9b can be made of an elastic material (such as silicone). Of course, the entire inner cover 9b can also be made of an elastic material. In this way, the notch 9b1 at the front end of the inner cover 9b can automatically open under the action of water pressure and automatically close by rebounding when the water pressure is insufficient. Specifically, when the water pressure in the inner cover body 9b is sufficient, the incision 9b1 will automatically open, releasing the water therein to spray forward. When there is no water in the inner cover body 9b and the water pressure is insufficient, the incision 9b1 will automatically close under the action of rebound, preventing the water therein from flowing out, which can play a certain role in preventing water leakage.

[0077] Among them, Figure 17 、 18 As shown, the outer cover 9c is positioned over the outer cover 9b, with a suitable gap between them to allow the inner cover 9b to expand, allowing the cutout 9b1 to open within this gap. When the cutout 9b1 opens, the upper and lower sidewalls of the inner cover 9b expand upward and downward, resting against the inner wall of the outer cover 9c. The front end of the outer cover 9c is provided with a plurality of water outlets 9c1 in the area corresponding to the open cutouts 9b1, allowing water inside to be ejected through the water outlets 9c1. To create a fan-shaped spray effect that expands outward in both directions, the front end of the outer cover 9c can be configured into an arc shape, with the water outlets 9c1 spaced apart along the arc (e.g., the outer arc of the front cross-section of the outer cover 9c). This is equivalent to forming an arc-shaped arrangement of the water outlets 9c1, allowing the water to be ejected in a fan-shaped pattern. The water outlets 9c1 are arranged at angles to each other, and are typically evenly distributed, with the angles between adjacent water outlets 9c1 being equal. Of course, they can also be arranged at multiple angles to create the effect of spraying in different directions. Taking the arc-shaped arrangement of the water outlet holes 9c1 as an example, the distribution area of the water outlet holes 9c1 can correspond to the position of the cutout 9b1 of the inner cover 9b. In this way, when the cutout 9b1 is opened, the water can be directly ejected through the water outlet holes 9c1. In order to form a wide-angle spray of water, the arc of the distribution area can be set to no less than 60 degrees, for example, 120 degrees, 150 degrees, etc. In addition, the outer cover 9c can be made of a hard material, such as a metal material such as iron, stainless steel, or other hard materials.

[0078] In this embodiment, the front end of the inner cover 9b is provided with an openable notch 9b1, while the outer cover 9c is sleeved over the outer side of the inner cover 9b and has an arc-shaped front end with multiple water outlet holes 9c1 distributed along the arc. This structure allows the sprayed water to spread in a fan-shaped manner to both sides, thereby achieving a wider spray range and a larger wetted area.

[0079] like Figure 17-19 As shown, the spray assembly 9 of this embodiment also includes a water trough box 9d installed at the front end of the water spray joint 9a. The rear end of the water trough box 9d is equipped with a mounting groove 9d1 for mounting the outer cover body 9c. In order to facilitate positioning and installation, the mounting groove 9d1 can be set to a waist-shaped structure, and the outer cover body 9c and the inner cover body 9b are also the same. The front end of the water spray joint 9a is also a waist-shaped structure. On the mounting groove 9d1, a connecting hole 9d2 is provided in the area corresponding to the distribution of the water outlet holes 9c1 of the outer cover body 9c to ensure smooth transmission of water. The front end of the water trough box 9d is provided with a diffusion groove 9d3 with a V-shaped cross section, which is intended to adapt to water sprayed in a fan-shaped manner, thereby optimizing the diffusion effect of the water flow. Communication hole 9d2 not only connects to diffusion groove 9d3 but is also located at the narrow end of the rear side of diffusion groove 9d3. This arrangement allows water sprayed from outer cover 9c to smoothly enter diffusion groove 9d3 and be sprayed outward, guided by the V-shaped side walls of diffusion groove 9d3, forming an ideal fan-shaped spray pattern. This arrangement allows spray assembly 9 to effectively diffuse water in both directions, thereby increasing coverage and spraying efficiency.

[0080] The diffusion groove 9d3 can be a strip-shaped structure extending to the left and right sides of the water tank box 9d, or can be a cone-shaped structure as a whole. Of course, in order to save space, the diffusion groove 9d3 is preferably a strip-shaped structure.

[0081] The spray assembly 9 used by the cleaning robot in this embodiment allows the sprayed water to spread in a fan-shaped pattern toward both sides of the body 1, achieving a wider spray range and a larger wetted area. Even if the water spray device (spray assembly 9) itself is small, it can ensure that the area covered by the spray is at least as wide as the width of the cleaning cloth, or even wider, significantly improving the cleaning effect of the cleaning robot during a single wiping process.

[0082] In addition, in actual use, usually the steam device and the spray assembly 9 are used separately, for example, when the steam device is used, the spray assembly 9 is not used, or when the spray assembly 9 is used, the steam device is not used. Of course, in special circumstances, the two can also be used simultaneously.

Although the present invention has disclosed the preferred embodiment as above, it is not intended to limit the form and style of the product of the present invention. Any technician familiar with this profession can make some changes or modifications to the technical content disclosed above without departing from the scope of the technical solution of the present invention. Any content that does not depart from the technical solution of the present invention falls within the patent scope of the technical solution of the present invention.
