[0038] This application provides a cleaning device, cleaning components, and a cleaning method, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0039] An embodiment of this application provides a cleaning device, which can be a steam floor scrubber or other device that cleans using steam.

[0040] Please see Figure 1 The cleaning equipment includes a body (not shown), a heating device 110, a jet nozzle 120, and a cooling device 130.

[0041] The machine body serves as the foundation for supporting other structures. A liquid storage container (not shown) may also be provided on the machine body. This container is connected to the heating device 110 to provide a cleaning medium for the heating device 110. The cleaning medium is typically water, including pure water and water containing cleaning solution. In other embodiments, the machine body may also be equipped with a water spray assembly 180 (see...). Figure 3 When other components require water supply, the liquid storage container can be connected to the corresponding component to achieve water supply. Furthermore, in other embodiments, the liquid storage container may not be provided, and water may be supplied from an external water source; this embodiment does not impose such restrictions. In addition, the machine body may be provided with a grip rod for user operation, and the bottom of the machine body may be provided with structures such as a roller brush 170.

[0042] The heating device 110 is mounted on the machine body to heat water entering the heating device 110 into steam, which is then supplied to the jet head 120. See here. Figure 2 The heating device 110 has a heating element 111, which has an inner cavity (not shown) and an inlet 112 and an outlet 113 communicating with the inner cavity. The inlet 112 is used to connect to a storage container or other water source to allow water flow. The heating element 111 is used to heat and atomize the water flowing into the inner cavity. The outlet 113 is used to discharge the water vapor formed after heating and atomization. See here for more details. Figure 1 The heating device 110 may also include a housing 114, which is disposed on the outside of the heating body 111 to achieve protection and heat insulation, thereby ensuring the safe use of the heating body 111.

[0043] Please continue reading. Figure 1 The jet head 120 is connected to the body, and is typically positioned near the front bottom of the body, although this embodiment does not limit its placement. The jet head 120 is connected to the air outlet 113 to spray heated and atomized water vapor outwards for cleaning. Here, the heating device 110 and the jet head 120 are connected via an air outlet pipe.

[0044] In one example, see Figure 1 The jet head 120 is generally plate-shaped, and a plurality of jet holes 121 are provided on the jet head 120. Please refer to... Figure 2The air outlet 113 of the heating device 110 is connected to a filter box 190. The filter box 190 has a chamber (not shown) containing a filter screen and other filter components (not shown). The spray head 120 and the filter box 190 are connected by a flexible hose 150. Here, the filter box 190 and the flexible hose 150 form the air outlet pipeline. The atomized water vapor supplied by the air outlet 113 is filtered by the filter box 190 and then supplied to the spray head 120 through the flexible hose 150, and sprayed outward from the spray hole 121. Both ends of the flexible hose 150 can be equipped with sealing rings or other sealing elements to achieve a sealed connection. For example, a sealing element 160 is provided at the air outlet 113 to seal the filter box 190 and the air outlet pipeline. Here, the flexible hose 150 can be easily bent and adjusted according to the structure and position of the body and other components to achieve connection and installation. Of course, in other embodiments, it can also be replaced by rigid tubing.

[0045] Of course, the specific structure of the jet head 120 and the specific connection structure between the heating device 110 and the jet head 120 are not limited to the above examples, and this embodiment does not impose any limitations on them. For example, the air outlet pipe can be a conduit connecting the air outlet 113 of the heating device 110 and the jet head 120 to enable communication between them. For another example, the air outlet pipe can be a corresponding docking structure between the air outlet 113 and the jet head 120, with the two docking to achieve communication. For yet another example, the air outlet pipe can be formed by other components connecting the air outlet 113 and the jet head 120, such as the aforementioned filter box 190 and hose 150.

[0046] Here, the heating device 110 may sometimes have a high heating temperature. For example, to ensure the water mist ejected from the jet 121 is highly visible so that the user can observe the operating status of the cleaning equipment, the heating device 110 needs to heat the water to a film boiling state. Therefore, at least a portion of the heating element of the heating device 110 needs to be maintained above the Leidenfrost characteristic temperature of water; for example, the highest temperature of at least a portion of the surface of the heating element is above 400°C, preferably maintained between 400-700°C, and exemplaryly, it can be maintained between 400°C-550°C, 550°C-700°C, etc. When the heating element is in this high temperature range, it may cause damage to surrounding components. For example, see... Figure 2In the aforementioned example, the sealing ring or other sealing element 160 located near the air outlet 113 of the heating device 110 is typically made of materials such as silicone. The high temperature of the heating element 111 exceeds the temperature resistance of these materials, leading to faster aging or even burning and damage to the sealing ring. This aging and damage will affect the sealing performance at the air outlet 113 of the heating device 110, thereby impacting the safety of the cleaning equipment and reducing its effectiveness.

[0047] Therefore, in order to reduce the temperature of the heating element 111 of the heating device 110, in the embodiments of this application, the cooling device 130 is provided on the machine body, and the cooling device 130 is used to drive the cooling medium to exchange heat with the heating element 111 to reduce the temperature of the heating element 111.

[0048] For example, in the first example, please refer to Figure 2 The cooling device 130 includes a heat exchange pipe 131 and a drive mechanism 132, wherein the heat exchange pipe 131 is connected to the heating device 110. Specifically, the heat exchange pipe 131 includes a first pipe section 1311, a first heat exchange pipe section 1312, and a second pipe section 1313 connected in sequence. The drive mechanism 132 is disposed in the heat exchange pipe 131, for example upstream of the first pipe section 1311, for pumping water into the heating device 110 via the first pipe section 1311, the first heat exchange pipe section 1312, and the second pipe section 1313.

[0049] The first pipe section 1311 is connected downstream of a liquid storage container to receive water flow.

[0050] The first heat exchange tube segment 1312 is wound around the heating element 111. Specifically, the heating element 111 has a first end 1111 and a second end 1112, with the water inlet 112 near the first end 1111 and the air outlet 113 near the second end 1112. The first heat exchange tube segment 1312 is wound around the circumferential surface of the heating element 111 near the second end 1112 to reduce the temperature of the heating element 111 at the second end 1112. Of course, in other embodiments, the first heat exchange tube segment 1312 may also be wound around other locations on the heating element 111 to cool other locations; this embodiment does not limit this.

[0051] When water flows through the first heat exchange tube section 1312, the lower-temperature water absorbs heat from the heating element 111, thereby reducing the temperature of the heating element 111. This prevents the overheated heating element 111 from affecting the seal 160 located at the second end 1112. Here, the first heat exchange tube section 1312 is made of a material with a high heat transfer coefficient to improve heat exchange efficiency; for example, it can be made of copper or other metals.

[0052] The second pipe section 1313 is connected to the inlet 112 to supply water to the heating device 110. Here, the first pipe section 1311 and the second pipe section 1313 can be connected using a flexible hose. Furthermore, the water is preheated by exchanging heat with the heating element 111 as it flows through the first heat exchange pipe section 1312. The preheated water then continues through the second pipe section 1313 and enters the inner cavity of the heating device 110 through the inlet 112 for further heating. Because the water is preheated by exchanging heat with the heating element 111 in the first heat exchange pipe section 1312, the heating element 111 can heat the water to the preset temperature more quickly, thus improving the heating efficiency of the heating element 111 and reducing the energy consumption required for heating the water.

[0053] As can be seen, the heat exchange pipe 131 connects the liquid storage container and the water inlet 112 of the heating element 111. The heat exchange pipe 131 serves as the heat exchange pipe of the cooling device 130 and is also configured to supply water to the heating device 110. Furthermore, the water transported to the heating element 111 via the heat exchange pipe 131 absorbs heat from the heating element 111, achieving both cooling of the heating element 111 and preheating of the water, thus realizing efficient energy utilization.

[0054] It is understood that in the above example, a portion of the heat exchange pipe 131 is wound around the heating element 111. In other embodiments, the heat exchange pipe 131 may not be wound around the heating element 111; heat exchange can be achieved simply by the heat exchange pipe 131 contacting the heating element 111. However, the winding arrangement provides a larger heat exchange area between the heat exchange pipe 131 and the heating element 111, resulting in a better heat exchange effect.

[0055] For example, in the second example, please refer to Figure 3The cleaning device further includes a roller brush 170 and a water spray assembly 180 mounted on the machine body. The water spray assembly 180 has at least one spray nozzle 181, which is oriented towards the roller brush 170 to spray water onto the roller brush 170 to wet it. The cleaning device also includes a water supply line 140, comprising a first line 141 and a second line 142. The first line 141 is located upstream of the second line 142 and the heat exchange line 131 and is connected to a storage container for water intake. The first line 141, the second line 142, and the heat exchange line 131 are connected by a T-junction 143. The second line 142 connects to the water inlet 112 for supplying water to the heating device 110. The heat exchange line 131 connects to the spray nozzle 181 for supplying water to the spray nozzle 181. Of course, it is understood that in other embodiments, the first pipe 141 may not be provided, and the second pipe 142 and the heat exchange pipe 131 may be directly connected to the liquid storage container to receive water flow.

[0056] Here, the heat exchange pipe 131 is configured to supply water to the spray nozzle 181 while simultaneously cooling the heating element 111. In other embodiments, the second pipe 142 may be wound around the heating element 111, either alone or simultaneously, to also configure the second pipe 142 as part of the heat exchange pipe 131. In this embodiment, specifically, the heat exchange pipe 131 includes a first pipe segment 1311, a first heat exchange pipe segment 1312, and a second pipe segment 1313 connected in sequence. The first pipe segment 1311 is connected to the first pipe 141 via the tee pipe 143 to receive water flow. The first heat exchange pipe segment 1312 is wound around the heating element 111, and the second pipe segment 1313 is connected to the spray nozzle 181.

[0057] Meanwhile, the drive mechanism 132 of the cooling device 130 includes a first pump body 1321 and a second pump body 1322. The first pump body 1321 is disposed in the first pipe 141, which communicates with the heat exchange pipe 131, and the second pump body 1322 is disposed in the second pipe 142, which communicates with the heat exchange pipe 131. That is, the drive structure is indirectly disposed in the heat exchange pipe 131, and the flow rate of the heat exchange pipe 131 is controlled by regulating the flow rate of the first pipe 141 and the second pipe 142. Of course, in other embodiments, the drive mechanism 132 may also be disposed in the heat exchange pipe 131.

[0058] In use, the first pump body 1321 drives water to flow into the first pipe 141, and the second pump body 1322 drives water to enter the second pipe 142 and regulates its flow rate, so that part of the water flows into the second pipe 142, while the remaining water continues to flow into the heat exchange pipe 131 under the drive of the first pump body 1321. When the water flows through the first heat exchange pipe section 1312, the lower-temperature water can absorb the heat of the heating element 111, thereby reducing the temperature of the heating element 111 and preventing the overheated heating element 111 from affecting the seal 160 located at the air outlet 113. Furthermore, the water is heated by heat exchange with the heating element 111 when it flows through the first heat exchange pipe section 1312. The heated water then continues through the third pipe section 1313 and enters the water spray assembly 180, and is sprayed outward through the spray nozzle 181 of the water spray assembly 180. Here, the water flows through the first heat exchange tube section 1312, where it exchanges heat with and is heated by the heating element 111. The heated water then has a better cleaning effect. Furthermore, the cleaning device eliminates the need for additional heating components, ensuring that the water sprayed from the water spray assembly 180 has a certain temperature, thus helping to save energy.

[0059] In the above embodiment, the cooling device 130 is configured to exchange heat with the heating element 111 using the cleaning medium (i.e., water) of the cleaning equipment as the cooling medium. The heat exchange pipe 131 of the cooling device 130 is also used to supply water to other components. Thus, the heat from the heating element 111 is absorbed by the water, preventing damage to the seal 160 or other components due to excessive temperature. Simultaneously, the water heats up by absorbing heat, and can then be used as a cleaning medium, thereby saving the electrical energy required to heat the cleaning medium.

[0060] In some embodiments, the cleaning device also includes a power source (not shown), which is mounted on the device body and connected to the heating device 110. Compared to cleaning devices connected to an external power source, wireless cleaning devices with an onboard power source offer greater convenience; however, they also have higher energy-saving requirements due to factors such as improved battery life. Therefore, applying the aforementioned heating device 110 to such cleaning devices with an onboard power source will have a greater beneficial effect, helping to improve the battery life of the cleaning device and providing users with a better user experience.

[0061] In other embodiments, the cooling device 130 may not use water or other clean media as the cooling medium; that is, it may include additional cooling media and heat exchange pipes 131. In one example, the cooling device 130 may be an air-cooled structure, which provides cooling air to the heating element 111 to reduce its temperature. In another example, the cooling device 130 may be a water-cooled structure, which includes heat exchange pipes 131 and a pump disposed within the heat exchange pipes 131. The heat exchange pipes 131 are in contact with the heating element 111 to absorb heat. The pump drives water or other cooling media to flow through the heat exchange pipes 131 to cool the heating element 111.

[0062] Accordingly, to better achieve the technical effects of this application, embodiments of this application also provide a cleaning component, which is used to clean equipment to achieve a cleaning effect. Here, the cleaning component includes a heating device 110 and a cooling device 130. The heating device 110 has a heating element 111, which has an inner cavity, a water inlet 112 and an air outlet 113 communicating with the inner cavity, and a water supply pipe 140 connected to the water inlet 112. The cooling device 130 is used to reduce the temperature of the heating element 111 to prevent the heating element 111 from affecting other components nearby.

[0063] In some embodiments, the cooling device 130 includes a heat exchange pipe 131 and a drive mechanism 132 disposed in the heat exchange pipe 131. The drive mechanism 132 is used to drive a cooling medium to move along the heat exchange pipe 131, and at least a portion of the heat exchange pipe 131 is in contact with the heating element 111.

[0064] In some embodiments, the heat exchange pipeline 131 is connected to the water inlet 112 to supply water to the heating device.

[0065] In some embodiments, the cleaning assembly further includes an air jet and a water jet 181, with the air outlet 113 connected to the air jet and the outlet end of the heat exchange pipeline 131 connected to the water jet 181.

[0066] Accordingly, please refer to Figure 4 In order to better achieve the technical effects of this application, the embodiments of this application also provide a cleaning method, which includes the following steps S100-S300.

[0067] In step S100, a cleaning device is provided, the cleaning device including a heating device 110, a jet nozzle 120, and a heat exchange pipe 131, the heating device 110 having a heating element 111. Here, at least a portion of the heat exchange pipe 131 is wound around the heating element 111.

[0068] In step S300, the water in the heat exchange pipe 131 exchanges heat with the heating element 111 to lower the temperature of the heating element 111 and heat the water in the heat exchange pipe 131.

[0069] In some embodiments, in step S100, the provided heat exchange pipeline 131 is connected to the heating device 110 to supply water to the heating device 110, and the heating device 110 is connected to the jet head 120.

[0070] Correspondingly, in step S300, the water in the heat exchange pipe 131 is preheated by absorbing heat from the heating element 111, and the preheated water is atomized by the heating device 110 and then sprayed out by the jet nozzle 120.

[0071] In some embodiments, in step S100, the provided cleaning device further includes a water supply line 140 and a spray nozzle 181. The water supply line 140 is connected to the heating device 110 to supply water to the heating device 110, and the heating device 110 is connected to the jet head 120. The heat exchange line 131 is connected to the spray nozzle 181 to supply water to the spray nozzle 181, and the heat exchange line 131 is at least partially wound around the heating element 111.

[0072] Correspondingly, in step S300, the water in the heat exchange pipe 131 is heated by the heating element 111 absorbing heat, and the heated water is sprayed out from the nozzle 181.

[0073] Application Example 1

[0074] In application example one, a steam floor scrubber is provided. The steam floor scrubber includes a heat exchange pipe 131, a heating device 110, and a jet nozzle 120. The heating device 110 has a heating element 111 with an air outlet 113. A sealing sleeve is provided at the air outlet 113. At least a portion of the heat exchange pipe 131 is wound around the heating element 111. Cold water supplied by the heat exchange pipe 131 exchanges heat with the heating element 111 of the heating device 110 to cool the heating element 111 and lower its temperature below the temperature resistance value of the sealing sleeve. Simultaneously, the water in the heat exchange pipe 131 absorbs heat from the heating element 111, thus raising its temperature.

[0075] Application Example 2

[0076] The structure of the steam floor scrubber provided in Application Example 2 is roughly the same as that in Application Example 1. The difference is that the heat exchange pipeline 131 includes a first pipe section 1311, a first heat exchange pipe section 1312, and a second pipe section 1313 connected in sequence. The first pipe section 1311 is equipped with a pump body. The first heat exchange pipe section 1312 is wound around the end of the heating body 111. The second pipe section 1313 is connected to the heating device 110.

[0077] In operation, cold water is pumped in through a pump body. The cold water sequentially passes through the first pipe section 1311, the first heat exchange pipe section 1312, and the second pipe section 1313 before entering the heating device 110 and being heated into steam before being ejected. Here, after the heating device 110 is powered on, the surface temperature of the heating element 111 can reach 400-700℃. The cold water entering the first heat exchange pipe section 1312 acts as a cooling agent, lowering the end surface temperature of the heating element 111 to approximately 100℃. This ensures the sealing sleeve on the heating element 111 meets its temperature resistance requirements, preventing it from being burned or damaged. Simultaneously, the heat from the heating element 111 is absorbed by the cold water, raising the temperature of the cold water flowing through the first heat exchange pipe section 1312 to approximately 60℃. This preheated water (60℃) is then passed into the heating device 110, shortening the steam formation time and thus improving the heating efficiency of the heating device 110.

[0078] Application Example 3

[0079] The steam floor scrubber provided in Application Example 3 has a structure that is largely the same as that in Application Example 1. The difference is that the steam floor scrubber also includes a water supply pipe 140, a roller brush 170, and a spray nozzle 181 facing the roller brush 170. The water supply pipe 140 is connected to the water inlet 112 of the heating device 110 to supply water to the heating device 110. The heat exchange pipe 131 includes a first pipe section 1311, a first heat exchange pipe section 1312, and a second pipe section 1313 connected in sequence. The first heat exchange pipe section 1312 is wound around the end of the heating body 111, and the second pipe section 1313 is connected to the spray nozzle 181.

[0080] Here, the water supply pipeline 140 is a steam water pipeline, used to supply water to the heating device 110. After the heating device 110 is powered on, it heats the water to a steam state.

[0081] The heat exchange pipe 131 is a water spraying pipe. When cold water enters the first heat exchange pipe section 1312 coiled on the heating body 111, it will absorb the waste heat on the surface of the heating body 111. The cold water is then heated to 70°C hot water and flows to the spray nozzle 181, where it is sprayed onto the roller brush 170 in the form of hot water. This helps to improve the cleaning efficiency and cleaning ability of the roller brush 170 in handling dirt.

[0082] Application Example 4

[0083] In Application Example 4, based on the steam floor scrubber provided in Application Example 2 or Application Example 3, the steam floor scrubber is configured to be wireless. That is, a power supply component is installed on the body of the steam floor scrubber to supply power to the pump and other drive mechanisms 132 in the heating device 110 and cooling device 130. Here, since the waste heat of the heating device 110 is used to heat the cold water in the water supply pipe 140, the power consumption of the heating device 110 for heating cold water is saved, thereby helping to improve the overall runtime of the machine.
