The present application provides a cleaning apparatus and a cleaning assembly, each of which is described in detail below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the respective embodiments have respective emphasis, and reference may be made to related descriptions of other embodiments for parts that are not described in detail in a certain embodiment.

Embodiments of the present application provide a cleaning apparatus that may be a steam operated floor scrubber or the like.

Referring to fig. 1, the cleaning apparatus includes a body (not shown), a heating device 110, a showerhead 120, and a cooling device 130.

Wherein the machine body is a foundation for bearing other structures. The body may also be provided with a reservoir (not shown) connected to the heating device 110 for providing a cleaning medium to the heating device 110, where the cleaning medium is typically water, including pure water and water containing cleaning liquid, etc. Of course, in other embodiments, when the machine body is further provided with a water spraying assembly 180 (see fig. 3) or other components requiring water supply, the liquid storage container may be connected to the corresponding components to supply water. In other embodiments, the liquid storage container may not be provided, and the water supply may be obtained from an external water source, which is not limited in this embodiment. In addition, the machine body can be further provided with a holding rod for operation of a user, and the bottom of the machine body can be further provided with a rolling brush 170 and other structures.

The heating device 110 is provided on the body to heat water entering the heating device 110 into water vapor, which is then supplied to the showerhead 120. Referring to fig. 2, the heating device 110 has a heating body 111, and the heating body 111 has an inner cavity (not shown) and a water inlet 112 and a gas outlet 113 communicating with the inner cavity. Here, the water inlet 112 is used to connect to a reservoir or other water source to receive a flow of water. The heating body 111 is used for heating and atomizing water flow entering the inner cavity. The air outlet 113 is used for discharging the water vapor formed after the heating and atomization. Here, referring to fig. 1, the heating device 110 may further include a housing 114, and the housing 114 is disposed outside the heating body 111 to achieve protection and heat insulation, so as to ensure safe use of the heating body 111.

With continued reference to FIG. 1, the showerhead 120 is attached to the body and may be generally disposed near the front side of the bottom of the body, although this embodiment is not intended to be limiting. The gas nozzle 120 is connected to the gas outlet 113, so that the water vapor formed after the heated atomization is sprayed out from the gas nozzle 120 to realize cleaning. Here, the connection between the heating device 110 and the showerhead 120 is realized by a gas outlet line.

In one example, referring to FIG. 1, the showerhead 120 is substantially plate-shaped, and a plurality of gas injection holes 121 are disposed on the showerhead 120. Referring to fig. 2 again, the air outlet 113 of the heating device 110 is connected to a filter box 190, the filter box 190 has a chamber (not shown) therein, a filter assembly (not shown) such as a filter net is disposed in the chamber, and the water spraying head 120 and the filter box 190 are connected by a hose 150. Here, the filter cassette 190 and the hose 150 form the outlet duct, and the atomized water vapor supplied from the outlet 113 is filtered by the filter cassette 190, supplied to the air nozzle 120 through the hose 150, and ejected from the air nozzle 121. Wherein, both ends of the hose 150 can be provided with a sealing element such as a sealing ring to realize a sealed connection, and exemplarily, the air outlet 113 is provided with a sealing element 160 to make the filter cartridge 190 and the air outlet pipeline connected in a sealed manner. Here, the 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, but it may be replaced with a hard pipe in other embodiments.

Of course, the specific structure of the showerhead 120 and the specific connection structure between the heating device 110 and the showerhead 120 are not limited to the above examples, and the present embodiment is not limited thereto. Illustratively, the gas outlet line may be a pipe connected between the gas outlet 113 of the heating device 110 and the gas nozzle 120 to communicate the two. In another exemplary embodiment, the gas outlet pipeline is a butt joint structure correspondingly disposed between the gas outlet 113 and the gas nozzle 120, and the two are butted to each other to achieve communication. Further illustratively, the outlet line is formed by other components coupled between the outlet port 113 and the showerhead 120, such as the filter cartridge 190 and the hose 150 previously described.

Here, the heating device 110 will sometimes have a higher heating temperature. For example, in order to enable high visibility of the mist ejected from the air ejection holes 121 for a user to observe the operation state of the cleaning apparatus, the heating device 110 needs to heat the water to a film boiling state. Thus at least part of the heating body of the heating device 110 needs to be maintained above the ledenverous characteristic temperature of water, e.g. the maximum temperature of at least part of the surface of the heating body is higher than 400 ℃, preferably the maximum temperature of part of the surface of the heating body is maintained between 400-700 ℃, exemplarily may be maintained between 400-550 ℃, 550-700 ℃ etc. When the heating body is in this higher temperature range, damage to the peripheral components may result. For example, referring to fig. 2, in the foregoing example, the sealing element 160, such as the sealing ring, disposed near the air outlet 113 of the heating device 110 is usually made of a material such as silica gel, and the heating body 111 with a higher temperature exceeds the temperature resistance of the material such as silica gel, which may cause the sealing ring to age more quickly or even burn and damage. Here, the aging and damage of the sealing ring will affect the sealing performance at the air outlet 113 of the heating device 110, and further affect the safety of the cleaning device, so that the using effect of the cleaning device is reduced.

Therefore, in order to lower the temperature of the heating body 111 of the heating device 110, in the embodiment of the present application, the cooling device 130 is disposed on the body, and the cooling device 130 is used to drive a cooling medium to perform heat exchange with the heating body 111 to lower the temperature of the heating body 111.

Exemplarily, in a first example, referring to fig. 2, the cooling device 130 comprises a heat exchange line 131 and a driving mechanism 132, and the heat exchange line 131 is connected to the heating device 110. Specifically, the heat exchange pipeline 131 comprises a first pipe section 1311, a first heat exchange pipe section 1312 and a second pipe section 1313 which are connected in sequence. The drive mechanism 132 is arranged in the heat exchange line 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.

Wherein the first pipe segment 1311 is connected downstream of a reservoir for access to the water flow.

The first heat exchange pipe section 1312 is wound around the heating body 111. Specifically, the heating body 111 has a first end 1111 and a second end 1112 opposite to each other, the water inlet 112 is close to the first end 1111, the air outlet 113 is close to the second end 1112, and the first heat exchange pipe section 1312 is wound on a circumferential surface of the heating body 111 close to the second end 1112 to reduce the temperature of the heating body 111 at the second end 1112. Of course, in other embodiments, the first heat exchange tube segment 1312 may also be wound around other positions on the heating body 111 to cool the other positions, which is not limited in this embodiment.

When water flows through the first heat exchanging pipe section 1312, the water having a lower temperature can absorb heat of the heating body 111, so that the temperature of the heating body 111 is reduced to prevent the sealing member 160 disposed at the second end 1112 from being affected by the heating body 111 having an excessively high temperature. Here, the first heat exchange tube section 1312 is made of a material having a high heat exchange coefficient so as to improve heat exchange efficiency, and may be made of, for example, copper or other metals.

The second pipe section 1313 is connected to the water inlet 112 to supply a flow of water to the heating device 110. Here, the first pipe segment 1311 and the second pipe segment 1313 may be hoses to facilitate connection. And, the water flow is preheated by heat exchange with the heating body 111 while passing through the first heat exchanging pipe section 1312, and the preheated water flow continues to pass through the second pipe section 1313 and enters the inner cavity of the heating device 110 through the water inlet 112 to be heated. Here, since the water flows in the first heat exchanging pipe section 1312 to exchange heat with the heating body 111 and to be preheated, the subsequent heating body 111 can heat the water to a preset temperature more quickly, which helps to improve the heating efficiency of the heating body 111, and meanwhile, the energy consumption required by the heating body 111 to heat the water is also reduced.

It is noted that, here, the heat exchange line 131 communicates the liquid storage container and the water inlet 112 of the heating body 111, and the heat exchange line 131 is configured to supply water to the heating device 110 while serving as the heat exchange line 131 of the cooling device 130. Furthermore, the water delivered to the heating body 111 through the heat exchange line 131 absorbs heat of the heating body 111, and preheats the water while cooling the heating body 111, thereby achieving effective use of energy.

It is understood that in the above example, a portion of the heat exchange line 131 is wound around the heating body 111. In other embodiments, the heat exchange pipeline 131 may not be wound around the heating body 111, and heat exchange can be achieved only by contacting the heat exchange pipeline 131 with the heating body 111, but the wound arrangement mode allows a larger heat exchange area to be formed between the heat exchange pipeline 131 and the heating body 111, so that the heat exchange effect is better.

Illustratively, in a second example, referring to fig. 3, the cleaning device further includes a rolling brush 170 disposed on the body, and a water spray assembly 180, the water spray assembly 180 having at least one water spray 181, the water spray 181 being disposed toward the rolling brush 170 for spraying water toward the rolling brush 170 to wet the rolling brush 170. Here, the cleaning device further comprises a water supply line 140, the water supply line 140 comprising a first line 141, a second line 142, the first line 141 being located upstream of the second line 142 and the heat exchange line 131 and being connected to a reservoir for receiving a flow of water. The first pipeline 141, the second pipeline 142 and the heat exchange pipeline 131 are connected through a tee 143. The second pipe 142 is connected to the water inlet 112 for supplying water to the heating means 110. The heat exchange pipeline 131 is communicated to the water spraying port 181, so as to supply water to the water spraying port 181. Of course, it is understood that in other embodiments, the first pipeline 141 may not be provided, and the second pipeline 142 and the heat exchange pipeline 131 may be directly connected to a liquid storage container to access water flow.

Here, the heat-exchange line 131 is configured to supply water to the water spray 181 while cooling the heating body 111, and in other embodiments, the second line 142 may be wound around the heating body 111 separately or simultaneously, so that the second line 142 is also configured as a part of the heat-exchange line 131. In the present embodiment, in particular, the heat exchange pipeline 131 comprises a first pipe segment 1311, a first heat exchange pipe segment 1312 and a second pipe segment 1313 which are connected in sequence, the first pipe segment 1311 is connected to the first pipeline 141 through the tee 143 to receive water flow, the first heat exchange pipe segment 1312 is wound on the heating body 111, and the second pipe segment 1313 is connected to the water spray 181.

Meanwhile, the driving 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 pipeline 141 communicating with the heat exchange pipeline 131, and the second pump body 1322 is disposed in the second pipeline 142 communicating with the heat exchange pipeline 131, that is, the driving mechanism is indirectly disposed in the heat exchange pipeline 131, and flow regulation of the heat exchange pipeline 131 is realized through flow regulation of the first pipeline 141 and the second pipeline 142. Of course, in other embodiments, the driving mechanism 132 may be disposed in the heat exchange line 131.

In use, the first pump 1321 drives water to flow in from the first conduit 141, the second pump 1322 drives water to flow in to the second conduit 142 and regulates the flow rate thereof such that a portion of the water flows in to the second conduit 142 and the remainder of the water continues to flow in to the heat exchange conduit 131 under the drive of the first pump 1321. When water flows through the first heat exchange pipe section 1312, the water having a lower temperature can absorb heat of the heating body 111, so that the temperature of the heating body 111 is lowered to prevent the sealing member 160 disposed at the gas outlet 113 from being affected by the heating body 111 having an excessively high temperature. And, the water flow is heated by exchanging heat with the heating body 111 when flowing through the first heat exchanging pipe segment 1312, and the heated water flow continuously enters the water spraying assembly 180 after passing through the third pipe segment 1313 and is sprayed outwards through the water spraying port 181 of the water spraying assembly 180. Here, the water flow exchanges heat with the heating body 111 in the first heat exchange pipe section 1312 and is heated, and the heated water flow will have a better cleaning effect. Meanwhile, the cleaning equipment can ensure that the water flow sprayed outwards by the water spraying component 180 has a certain temperature without additionally arranging a heating component, and is beneficial to saving energy.

In the above embodiment, the cooling device 130 is configured to exchange heat with the heating body 111 using the cleaning medium (i.e., water) of the cleaning apparatus as the cooling medium, and the heat exchange line 131 of the cooling device 130 is simultaneously used to supply water to other components. Thus, heat of the heating body 111 is absorbed by water to prevent the heating body 111 from damaging the sealing member 160 or other components due to an excessively high temperature. At the same time, the water is warmed up due to the absorption of heat, after which the water can be used as a cleaning medium and the electric power required for heating the cleaning medium can be saved.

Here, in some embodiments, the cleaning apparatus further has a power supply (not shown) disposed on the body and connected to the heating device 110. Compared with cleaning equipment connected with an external power supply, the wireless cleaning equipment with the onboard power supply has better convenience, but has higher energy-saving requirements for the reasons of improving cruising ability and the like. Therefore, the application of the aforementioned heating device 110 to such a cleaning apparatus with an on-board power supply has a better beneficial effect, which helps to improve the cruising ability of the cleaning apparatus, so that the user has a better experience in using the cleaning apparatus.

In addition, in other embodiments, the cooling device 130 may not use cleaning medium such as water as cooling medium, that is, a cooling medium and a heat exchange pipeline 131 and the like may be additionally provided. In one example, the cooling device 130 may be an air-cooling structure for supplying cooling air to the heating body 111 to reduce the temperature of the heating body 111. In another example, the cooling device 130 may be a water cooling structure including a heat exchange pipe 131 and a pump body disposed in the heat exchange pipe 131, and the heat exchange pipe 131 is in contact with the heating body 111 to absorb heat. The pump body is used for driving water or other cooling media to flow in the heat exchange pipeline 131 so as to cool the heating body 111.

Accordingly, to better achieve the technical effects of the present application, embodiments of the present application also provide a cleaning assembly used for a cleaning apparatus to achieve the cleaning effect. Here, the cleaning assembly includes a heating device 110 and a cooling device 130. The heating device 110 has a heating body 111, the heating body 111 has an inner cavity, and a water inlet 112 and an air outlet 113 communicated with the inner cavity, and the water supply pipeline 140 is communicated to the water inlet 112. The cooling device 130 is used to reduce the temperature of the heating body 111 to avoid the heating body 111 from affecting other components close thereto.

In some embodiments, the cooling device 130 comprises a heat exchange line 131 and a driving mechanism 132 disposed in the heat exchange line 131, the driving mechanism 132 is used for driving a cooling medium to move along the heat exchange line 131, and at least a portion of the heat exchange line 131 is in contact with the heating body 111.

In some embodiments, the heat exchange line 131 is connected to the water inlet 112 to supply water to the heating device.

In some embodiments, the cleaning assembly further comprises an air outlet 113 connected to the air outlet and a water outlet 181, and the outlet end of the heat exchange line 131 is connected to the water outlet 181.

Accordingly, referring to fig. 4, in order to better achieve the technical effects of the present application, an embodiment of the present application further provides a cleaning method, which includes the following steps S100 to S300.

In step S100, there is provided a cleaning apparatus including a heating device 110, a gas showerhead 120, and a heat exchange line 131, the heating device 110 having a heating body 111. Here, at least a portion of the heat exchange line 131 is wound around the heating body 111.

In step S300, the water in the heat exchange line 131 is heat-exchanged with the heating body 111 to reduce the temperature of the heating body 111 and heat the water in the heat exchange line 131.

In some embodiments, in step S100, the provided heat exchange line 131 is communicated to the heating device 110 to supply water to the heating device 110, and the heating device 110 is connected to the showerhead 120.

Correspondingly, at this time, in step S300, the water in the heat exchange pipeline 131 is preheated by absorbing heat from the heating body 111, and the preheated water is sprayed from the gas nozzle 120 after being atomized by the heating device 110.

In some embodiments, in step S100, the provided cleaning apparatus further comprises a water supply line 140 and a water spray 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 showerhead 120. The heat exchange line 131 is connected to the water spray 181 to supply water to the water spray 181, and the heat exchange line 131 is at least partially wound around the heating body 111.

Correspondingly, at this time, in step S300, the water in the heat exchange pipeline 131 absorbs heat from the heating body 111 and is heated, and the heated water is sprayed from the water spraying port 181.

The cold water supplied by the heat exchange pipeline 131 exchanges heat with the heating body 111 of the heating device 110 to cool the heating body 111, and the temperature of the heating body 111 is lower than the temperature resistance value of the sealing rubber sleeve. At the same time, the water in the heat exchange line 131 absorbs heat from the heating body 111, and the temperature of the water is increased.

Here, the surface temperature of the heating body 111 after the heating device 110 is powered on can reach 400-700 ℃, and cold water can play a role in cooling when entering the first heat exchange tube segment 1312, so that the surface temperature of the tail end of the heating body 111 is reduced to about 100 ℃ to meet the temperature resistance value of a sealing rubber sleeve sleeved on the heating body 111, and the sealing rubber sleeve cannot be burnt and damaged. Meanwhile, the heat of the heating body 111 is absorbed by the cold water, so that the temperature of the cold water flowing through the first heat exchange pipe section 1312 is raised to about 60 ℃. Furthermore, the water preheated to 60 ℃ is introduced into the heating device 110 for heating, so that the time for forming steam is shortened, and the heating efficiency of the heating device 110 is improved.
