Cleaning device with rolling brush

Technical Field

The invention relates to the technical fields of rolling brush electric mops, floor washing machines, dust collectors, floor sweeping machines and the like, in particular to a cleaning device with rolling brushes.

Background

In a cleaning device such as a roller brush electric mop, a floor cleaner, a vacuum cleaner, or a sweeper, the roller brush is one of important technical means for improving cleaning performance, and the roller brush is generally operated in such a manner that the roller brush is brought into rotational contact with a surface to be cleaned, and the surface to be cleaned is cleaned by the contact.

In order to improve the cleaning performance, there are proposed a scheme of spraying a cleaning liquid such as a detergent, water, etc. before and after the rolling brush, so that the cleaning performance is improved by wetting the rolling brush or wetting the surface to be cleaned, and in addition, in order to further improve the cleaning performance, there are proposed a scheme of heating the cleaning liquid, that is, using a hot cleaning liquid to improve the cleaning performance, but there are many different schemes of how the hot cleaning liquid is generated and supplied at present, which can be roughly divided into two kinds: the cleaning liquid in the liquid storage tank is heated by adopting electric heat or chemical energy, the liquid storage tank is connected with the rolling brush through a pipeline, the conveyed cleaning liquid is sprayed on the rolling brush or the surface to be cleaned, two types of cleaning liquid are sprayed on the rolling brush, one type of cleaning liquid is sprayed on the upper side outside the rolling brush, and the other type of cleaning liquid is sprayed from the cleaning part of the rolling brush after being split from the interior of the rolling brush, so that the scheme has the advantages of long conveying distance, high energy consumption and slow response, and in addition, the problem of high-pressure and high-heat storage after the liquid storage tank is heated is related to how to ensure safety is a big problem; the other proposal is specifically proposed by the applicant, namely, the cleaning solution is directly heated in the rolling brush, and the heated rolling brush indirectly heats the cleaning solution after encountering the cleaning solution, so that the hot cleaning effect is obtained.

Accordingly, the applicant has continued intensive studies, and the applicant will propose a cleaning device having a roll brush in the present disclosure, which can further improve the endurance and heating response performance of the cleaning device.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a cleaning device with a rolling brush, which can further improve the endurance and heating response performance of the cleaning device.

Compared with the prior art, the invention provides a cleaning device with a rolling brush, which comprises a clean water tank and the rolling brush, wherein the clean water tank is used for supplying cleaning liquid, the cleaning liquid in the clean water tank is heated by electric heating and/or chemical reaction to obtain the cleaning liquid with a first temperature, and the electric heating component of the electric heating is supplied with electric energy by commercial power and/or a battery pack powered by the commercial power; the battery pack is provided with a battery pack, a battery pack and a heating part, wherein the battery pack is electrically connected with the battery pack, the battery pack is provided with a battery pack, and the battery pack is provided with a battery pack; the first temperature may or may not be user settable.

The first temperature may be set by a user or may not be set, and the first temperature may be a temperature threshold or a temperature interval.

The cleaning liquid in the clean water tank may be a cleaning liquid with a first temperature which is filled from an external water tank, for example, the base station is provided with a heating water tank provided with an electric heating element, the cleaning liquid is first heated in the heating water tank (supplied with electric energy by mains electricity and/or a battery pack supplied with electric energy by mains electricity), and the cleaning liquid after reaching the first temperature or above is pumped into the clean water tank.

It is also possible to provide an electric heating element in the fresh water tank, which is supplied with electric energy by mains electricity and/or by a battery pack supplied by mains electricity, so as to directly heat the cleaning liquid in the fresh water tank.

Alternatively, a heating element for water reaction is put into the clean water tank, and the cleaning liquid at the first temperature is obtained by heating through chemical reaction.

In summary, the energy for heating the cleaning liquid to the first temperature in the solution of the present disclosure is not dependent on the battery pack, but the battery pack can be heated when the battery pack has a charging condition, but in essence, the energy for heating the cleaning liquid to the first temperature in the solution of the present disclosure is from an external energy supply.

After adopting the structure, compared with the prior art, the invention has the following advantages:

Since the cleaning liquid at the first temperature is supplied with electric energy and/or chemical reaction supply energy by the mains supply and/or a battery pack supplied by the mains supply, when a higher temperature is required to be obtained during cleaning, the heating part can be started, and the electric energy required by the cleaning liquid to reach the higher temperature is reduced relatively, so that the improvement of the cruising is facilitated, and from another aspect, the battery pack can be smaller while maintaining the same working time.

Since the cleaning liquid already has the first temperature, the time to reach a higher temperature can be reduced, thereby contributing to further improvement of the heating response performance of the cleaning device.

The following structure is further combined: since the heating part is arranged on the periphery of the outer periphery of the rotary cylinder body in a circumferential manner and is in contact and/or clearance fit with the outer periphery of the rotary cylinder body, the heating part is used for heating the cleaning part of the rotary cylinder body and/or the cleaning liquid supplied to the cleaning part, so that heat generated by the heating part can be quickly transferred to the cleaning part and/or the cleaning liquid supplied to the cleaning part, and is effectively used immediately after being transferred thereto, while heating the cleaning liquid supplied to the cleaning portion means that one of the wet cleaning portion heats the cleaning liquid in the cleaning portion while passing through the cleaning portion, and the other of the wet cleaning portion heats the cleaning liquid while falling onto the cleaning portion and/or heats the cleaning liquid before falling onto the cleaning portion. After the design, the heated cleaning liquid falls onto the cleaning part immediately to participate in the next cleaning work, the heat utilization rate is very high, and little waste is caused, so that the consumption of electric energy of the battery pack is reduced, and the cruising time of the cleaning device can be further improved.

Meanwhile, since the heating part is attached to and/or in clearance fit with the periphery of the rotary cylinder body, the heating part is used for heating the cleaning part of the rotary cylinder body and/or the cleaning liquid supplied to the cleaning part, so that less heat is required for reaching a certain temperature during heating, the response performance can be greatly improved, and the cleaning liquid is overlapped to have the first temperature, so that after the heating part is opened, the cleaning part of the rotary cylinder body and/or the cleaning liquid supplied to the cleaning part can reach the required working temperature quickly in the disclosure, and the response performance can be greatly improved.

In summary, the present disclosure can further improve the endurance and heating response performance of the cleaning device.

In addition, because the cleaning liquid reaches higher temperature through the heating part, so the requirement on the first temperature is reduced, and the scheme of the disclosure is beneficial to avoiding the problem of high pressure and high heat storage of the clean water tank (liquid storage tank) caused by overhigh temperature, so the use safety is also improved.

As shown in fig. 42, the clean water tank 64 is provided with an electrode 65 and a heating sheet 66, the heating sheet 66 is a conventional one, and the heating sheet 66 is, for example, a PTC heating sheet, a graphene heating sheet, or the like. The clean water tank 64 is mounted on the main body 62, and the clean water tank 64 is electrically connected to an external power supply circuit through the electrode 65, the power supply circuit is generally electrically connected to the mains supply, that is, when the main body 62 is placed on the base station 63, the main body 62 is powered by the power supply of the base station 63, and the power supply of the base station 63 is the mains supply, so that the main body 62 is connected to the mains supply through the base station 63, the power supply circuit obtains the mains supply, and the heating plate 66 can heat the clean water tank 64 according to the set temperature. The set temperature is characterized by utilizing the characteristic that the existing intelligent cleaning device is provided with a control unit, the temperature sensing assembly can be added, the temperature sensing assembly feeds back signals to the control unit, and the control unit controls the power supply circuit to heat the clean water tank 64, so that the set temperature is achieved. With the control unit, the first temperature can be set as desired. The power supply circuit is of conventional configuration and will not be described in detail herein.

The specific mode of reservation can be that means such as touch, button are directly set on cleaning device, also can be that remote setting such as cell-phone APP, all are applicable to the setting technical means that is applicable to this disclosure.

In some embodiments, a switch module is also included for a user to control whether the heating portion is on while cleaning the surface being cleaned. For example as follows: the cleaning procedure, for example a user manually turns on the heating section while the rotating cylinder 3 rotates, and the liquid outlet section may or may not spray liquid, which is generally required, so that the hot and wet cleaning section has a better cleaning effect on the surface to be cleaned. The manual opening can be realized by adopting a common switch structure such as a touch switch, a mechanical switch and the like. After the design, a user can start the heating part according to the self requirement, and the heating part can not be always started, so that the cruising time can be further improved.

In some embodiments, a prompt module is also included for prompting whether the fresh water tank is ready, which means whether the first temperature is reached.

After the design, the user can know whether the water purifying tank is ready more conveniently, and the user experience is improved.

The present disclosure exemplifies a roll brush comprising one rotary cylinder 3, and of course, the rotary cylinder 3 may be plural, such as two, three, etc., but regardless of the plural, the present invention also indicates that at least one rotary cylinder 3 is provided with the heating part of the present invention when having plural rotary cylinders 3, and the like, and the roll brush can be adaptively adjusted or simply duplicated with reference to one scheme. When the heating portions are required to be provided for the plurality of rotary cylinders 3, it is possible to skillfully provide the heating portions between the adjacent two rotary cylinders 3, that is, to provide the adjacent two rotary cylinders 3 with one heating portion in common, but the heating portions at this time are provided on both sides thereof to be able to transfer heat to the corresponding rotary cylinder 3, for example, the heating members 5 are provided on both sides, or the transition water tank 6 transfers heat to the corresponding rotary cylinder 3 on both sides after the transition water tank 6 is heated.

The cleaning part of the rotary cylinder 3 is generally the outermost layer, the thickness is determined according to the cleaning performance or the requirement of the surface to be cleaned, and by adopting the scheme of the invention, the existing rotary cylinder 3 can be used without modifying the original rotary cylinder 3 structure, and the replacement and use cost of the rotary cylinder 3 for users is hardly increased.

The cleaning liquid may be used in combination with other devices, such as spraying water on the surface to be cleaned, and the heated cleaning portion may achieve a better cleaning effect when exposed to wet surface to be cleaned, where the heated object is the cleaning portion, and the cleaning device is provided with other liquid supply structures, for example, a liquid outlet portion of the disclosure, where the cleaning liquid is sprayed on the cleaning portion, and the cleaning portion with the cleaning liquid is heated and used, where the surface to be cleaned is dry, but under the action of the heated wet cleaning portion, a better cleaning effect may be achieved, for example, the solution including the labyrinth flow channel and/or the transition water tank described in the following embodiments may be used in any combination, i.e., the cleaning liquid may be sprayed and supplied by the liquid supply structure, or the cleaning liquid may be sprayed by the liquid supply structure, and the transition water tank may be simultaneously supplied by the liquid supply structure, and so on.

The term "water" or "water-related" as used in this disclosure is not meant to refer to only one instance of water, but rather is commonly referred to as a clean water tank, where water refers to a cleaning liquid, which may be water alone, a mixture of water and a cleaning agent, or a mixture of water and a disinfectant.

The present disclosure heats the outer periphery of the rotary cylinder 3, i.e., the cleaning portion, by the heating portion being in close fit with the outer periphery of the rotary cylinder 3, and therefore, heat generated by the heating portion can be transferred to the cleaning portion as soon as possible. Therefore, less heat is required to reach a certain temperature during heating, and the response performance can be greatly improved, that is, after the heating part is turned on, in the present disclosure, the cleaning part of the rotary cylinder 3 can reach the required working temperature soon, so that the response performance can be greatly improved.

In summary, the present disclosure can further improve the energy utilization efficiency and the response performance.

In some embodiments, a cleaning program may be added to the original control unit of the cleaning apparatus, under which the heating portion is used to heat the cleaning portion of the rotating cylinder 3 and/or the cleaning liquid supplied to the cleaning portion to clean the surface to be cleaned. The cleaning procedure, such as the manual turning on of the heating part by the user, while the rotary cylinder 3 rotates, the liquid outlet part may or may not spray liquid, and generally needs to spray liquid, so that the hot and wet cleaning part has better cleaning effect on the surface to be cleaned.

In some embodiments, for example, as shown in fig. 23, the disclosure proposes a liquid outlet portion, including a body extending along an axial direction of a rotary cylinder 3, the body is provided with a liquid outlet channel 14 disposed along the axial direction, a start point and an end point of the liquid outlet channel 14 along the axial direction are respectively used as two ends of the liquid outlet channel 14, the body is located at one side of the rotary cylinder 3 and is provided with a plurality of liquid outlet holes 7 sequentially disposed along the liquid outlet channel 14, each liquid outlet hole 7 is respectively communicated with the liquid outlet channel 14, one of the two ends is used as a liquid inlet 15, and a size of each liquid outlet hole 7 gradually increases along the axial direction from the liquid inlet 15 to the other end of the liquid outlet channel 14.

After adopting above-mentioned structure, this disclosure has following advantage: since the size of each liquid outlet 7 gradually increases along the axial direction of the rotary drum 3 from the liquid inlet of the liquid outlet channel 14 toward the other end of the liquid outlet channel 14, when water is discharged, the liquid outlet 7 on the side close to the liquid inlet 15 has a high flow velocity due to the high water pressure on the side close to the liquid inlet 15, when the liquid outlet 7 on the side close to the liquid inlet 15 becomes smaller, the liquid outlet 7 on the side close to the liquid inlet 15 has a small flow cross section, although the flow velocity is high, the water yield is smaller than that of the original structure, while the liquid outlet 7 on the slightly far point has a relatively low flow velocity, but the water yield is larger than that of the original structure due to the hole is larger, the wet degree of the cleaning part of the rotary drum 3 is relatively uniform based on the scheme, so that the wet degree of the cleaning part of the rotary drum 3 is relatively uniform due to the adoption of the technical scheme of one end liquid inlet in the two ends of the liquid outlet channel, and an advantageous precondition is provided for reducing the volume of the rolling brush due to the simple structure.

The present disclosure also proposes a liquid outlet portion, which is characterized in that the interval between each adjacent liquid outlet holes 7 is gradually smaller along the axis direction, as compared with the liquid outlet portion described above, as shown in fig. 24.

After adopting above-mentioned structure, this disclosure has following advantage: because from the inlet of liquid runner 14 to the direction of the other end of liquid runner 14, the interval between each adjacent liquid outlet 7 diminishes along the axis direction gradually, so the distribution of liquid outlet 7 that is close to inlet 7 one side is sparse, and the distribution of liquid outlet 7 that is far away from inlet one side is dense, so the clean portion of rotatory barrel 3 by moist degree just can be comparatively even, therefore when adopting the technical scheme of the one end feed liquor in the both ends of liquid runner, still be favorable to comparatively even to the moist degree of clean portion of rotatory barrel 3, because simple structure to provide an advantageous precondition for reducing the volume of round brush.

In some embodiments, the liquid outlet channel 14 is preferably a linear channel, and the linear channel may be parallel to the axial direction of the rotary cylinder 3 or may be inclined to the axial direction of the rotary cylinder 3. The expression "the body is provided with the liquid outlet passage 14 arranged in the axial direction" is not required to define the liquid outlet passage 14 to be arranged in parallel with the axial direction, but is required to cover the cleaning portion of the rotary cylinder 3, so that the liquid outlet passage 14 is required to be capable of delivering the liquid to the liquid outlet holes 7, and thus the expression "the body is provided with the liquid outlet passage 14 arranged in the axial direction" is provided.

Because of the manufacturing cost and difficulty, generally, the size of the liquid outlet channel 14 is generally uniformly arranged along the axis direction of the rotary cylinder 3, if the liquid outlet channel 14 is to be made into different sizes along the axis direction of the rotary cylinder 3, the difficulty is great on one hand, and the cost is high on the other hand, so in order to achieve the purpose that the wetting degree of the cleaning part is relatively uniform, the two technical routes of the liquid outlet part are beneficial to simplifying the structure of the liquid outlet channel 14, that is, the technical case that the size of the liquid outlet channel 14 is generally uniformly arranged along the axis direction of the rotary cylinder 3 is suitable for the two technical routes of the liquid outlet part, in other words, the liquid outlet part of the disclosure does not need to make special arrangement of the size of the liquid outlet channel 14.

In some embodiments, the heating part includes a heat conducting member 4, in which a flow channel 14 is provided in the heat conducting member 4, and a heating part in which the flow channel 14 is not provided in the heat conducting member 4, as shown in fig. 1 to 7, for example, refer to embodiments one to six.

In some embodiments, as shown in fig. 16, 19, 20, and 25, the flow channel 14 is provided in the heat conducting member 4, which is advantageous for improving the utilization rate of energy and reducing the volume, but increases the thickness of the heat conducting member 4, and then the disclosure proposes: the surface of the heat conductive member 4 facing the rotary cylinder 3 is provided with a convex portion extending along the flow path 14 and protruding toward the rotary cylinder 3 and/or a convex portion protruding toward the rotary cylinder 3 at the flow path 14, in which case the first convex portion 36 is provided with a convex portion extending along the flow path 14 and protruding toward the rotary cylinder 3, the second convex portion 37 is provided with a convex portion extending along the flow path 14 and protruding toward the rotary cylinder 3, and the third convex portion is provided with both the first convex portion 36 and the second convex portion 37. In either case, the thickness is reduced to a certain extent, the weight is reduced, and in particular the third, most, but the first facilitates the positioning of the heating element 5 on the rear face and the second facilitates the smoother surface of the side of the heat-conducting element 4 facing the rotating cylinder 3.

In some embodiments, as shown in fig. 16, 19 and 20, the first protrusion 36 is an arc-shaped protrusion, and of course, as shown in fig. 21, the second protrusion 37 may also be an arc-shaped protrusion. When the first protruding portion 36 is an arc protruding portion, since it is located on the side of the heat conducting member 4 facing the rotary cylinder 3, the arc protruding portion is provided to facilitate contact with the cleaning portion of the rotary cylinder 3, and is not damaged on one side and less hindered on the other side.

In some embodiments, as shown in fig. 16, 19, 20 and 25, arc-shaped concave 38 is formed between adjacent convex parts, especially on the side of the heat conducting member 4 facing the rotary cylinder 3, the arc-shaped concave 38 is easy to process, has little influence on the strength of the heat conducting member 4, is not easy to concentrate stress, has no damage to the cleaning part, and has little obstruction to the cleaning part.

In some embodiments, as shown in fig. 2, 4, 16, 19 and 20, the cleaning device further comprises a dirt scraping assembly and a liquid outlet part, wherein the liquid outlet part is provided with a liquid outlet hole 7, the liquid outlet hole 7 is used for outputting cleaning liquid to the cleaning part, and the dirt scraping assembly is used for cleaning the cleaning part wetted by the cleaning liquid.

In some embodiments, as shown in FIGS. 2, 3, 10, 17, 18, further comprising suction port 13, the contaminated water is sucked away by suction port 13. Thus, the sewage is treated in time, and the sewage can be prevented from polluting the surface to be cleaned again. Suction port 13 is connected with suction pipe 32, and sewage is sucked through suction port 13, suction pipe 32 in order, suction port 13, suction pipe 32, cleaning device's filtration subassembly, cleaning device's negative pressure subassembly in order intercommunication setting.

In some embodiments, as shown in FIG. 2, a dirt scraping assembly is provided to bypass suction opening 13. By such design, adverse effects of the dirt scraping assembly on the flow cross section of the suction port 13 can be avoided, and the performance of the suction port 13 can be exerted. The avoidance of the suction port 13 does not require absolute avoidance, but rather means that certain measures are taken to reduce the shielding of the suction port 13 by the dirt scraping assembly, and when the avoidance is to a certain extent, i.e. the adverse effect on the suction port 13 is small, the avoidance is also possible. Of course, it is better to be able to avoid completely.

In some embodiments, as shown in FIG. 2, suction opening 13 is forward and the dirt scraping assembly is rearward in the direction of rotation of rotating cylinder 3. After the design, the cleaning part is subjected to one-time treatment of the suction opening 13 before the dirt scraping assembly, so that the burden of the dirt scraping assembly is favorably reduced, and conversely, the cleaning effect of the cleaning part can be better achieved after the dirt scraping assembly is subjected to one-time treatment of the suction opening 13.

In some embodiments, as shown in FIGS. 2, 39 and 40, suction opening 13 is located on the rear side of rotary cylinder 3 and the dirt scraping assembly is located on the upper side of suction opening 13. After the design, sewage naturally flows downwards after being treated by the sewage scraping assembly, and the suction port 13 can just suck the sewage in time, so that the cleaning efficiency is improved.

The following examples further illustrate related aspects of the disclosure:

embodiment one:

the disclosure provides a round brush, including rotatory barrel 3, the circumference of rotatory barrel 3 periphery is equipped with the heating portion, and heating portion pastes with rotatory barrel 3 periphery, and this heating portion is used for the clean portion of heating rotatory barrel 3. Therefore, the heat generated by the heating part is directly attached to the cleaning part and transferred to the cleaning part, the distance for transferring the heat is zero, the use efficiency is high, the waste of the heat is reduced, and the effective utilization rate of the heat is improved.

The heating part includes a heat conduction member 4 and a heating member 5, the heat conduction member 4 is disposed around the circumference of the outer circumference of the rotary cylinder 3, and the heating member 5 is connected with the heat conduction member 4. Through the design, heat can be conveniently transferred through the heat conducting piece 4, on the one hand, the heating piece 5 relates to the power supply problem, and the structure of the heating piece 5 can be conveniently arranged according to the design, on the other hand, through the heat conducting piece 4, the heat transfer can be simple and efficient more comprehensively, thereby being favorable to guaranteeing the heated area of the cleaning part, simultaneously being favorable to reducing the installation quantity of the heating piece 5, and avoiding increasing excessive weight.

The novel rotary brush further comprises a rolling brush frame 1, the rolling brush frame 1 is provided with a first opening 9 for detachably mounting the rotary cylinder body 3, and a heating part is arranged in the first opening 9. By the design, the replacement of the rotary cylinder body 3 is not affected, and after the rotary cylinder body 3 is replaced, the space between the heating part and the rotary cylinder body 3 does not need to be adjusted any more, namely, the rotary cylinder body can be directly used after being replaced, so that the rotary cylinder body is greatly convenient for users to use.

In some embodiments, as shown in fig. 1, 2 and 3, the upper cover 2 is detachably connected to the brush holder 1, the heating part is located at the lower side of the upper cover 2, and after the upper cover 2 is removed, the heating part can be seen, and in addition, after the upper cover 2 is removed, the rotary cylinder 3 can be removed in the up-down direction for cleaning or replacement, that is, the upper cover 2 is used as a limiting mounting piece of the rotary cylinder 3 at the same time. The design is greatly convenient for manufacturing the invention and is convenient for daily users.

In some embodiments, as shown in fig. 4 and 5, the heating body comprises a continuous heat conducting member 4 arranged in the axial direction and a heating member 5 arranged discontinuously, the heat conducting member 4 being on the outside and the heating member 5 being on the inside, the heat conducting member 4 isolating the heating member 5 from the rotary cylinder 3. In this way, on the one hand, the arrangement and the installation quantity of the heating elements 5 are simplified, and on the other hand, the heat conducting elements 4 isolate the heating elements 5 from the rotary cylinder 3, so that the heating elements 5 are protected, and the service life is prolonged.

The heating portions are continuously provided in the axial direction of the rotary cylinder 3. By the design, the cleaning part can be heated uniformly, and drying performance is facilitated.

And the heat insulation structure is used for enabling most of heat generated by the heating part to be transferred to the cleaning part. The heat-insulating structure is, for example, a heat-insulating layer provided at the rear and around the heating element 5, so that the heat of the heating element 5 is mainly transferred to the front side, i.e., mainly transferred to the heat-conducting element 4, and the heat-conducting element 4 transfers the heat to the cleaning portion. The design is beneficial to reducing waste and improving the heat utilization rate.

One side of the heating portion facing the rotary cylinder 3 includes an arc structure disposed around the rotary direction of the rotary cylinder 3, in this example, the heat conducting member 4 is disposed in an arc structure, that is, the heat conducting member 4 is a concave arc plate. After the design, concave arc matches with the cleaning part outer peripheral face, is favorable to the smooth and easy rotation of cleaning part on the one hand, and on the other hand is favorable to concave arc and cleaning part good laminating to promote heat transfer efficiency.

In this example, the transition water tank 6 is not provided, and the above structure can be shown with reference to fig. 1, 2, 4, and 5, and other structures of the transition water tank 6 can be omitted in fig. 2, 4, and 5 to form this example.

In this example, the liquid outlet portion and the heating portion share a frame, the frame has a front panel, each liquid outlet hole 7 is disposed on the front panel, each liquid outlet hole 7 is communicated with the liquid supply assembly, and the heating portion assembly is detachably connected with the frame.

Embodiment two:

the embodiment differs from the first embodiment in that a transition water tank 6 is added, and a heating portion for heating the cleaning liquid supplied to the cleaning portion.

When the transition water tank 6 is added, the structure is as follows: the heating portion includes transition water tank 6, and the heating element 5 of heating portion is arranged in transition water tank 6, and transition water tank 6 is used for being connected with the water source, and heating element 5 is arranged in the cleaning liquid of heating transition water tank 6, and the cleaning liquid after the heating flows to the cleaning portion, and in this way, the cleaning portion is also heated by the heat that the cleaning liquid brought.

The transition tank 6 adopts a small capacity which is smaller than the capacity of the water source.

Preferably, the small volume is within six times, including six times, the volume of the cleaning liquid supply flow per unit time. The supply amount of the cleaning liquid per unit time is set according to the cleaning requirement, and in general, it is advantageous to achieve or exceed the supply amount for better cleaning performance, but if the capacity of the transition water tank 6 is not limited, it is also important that the capacity of the transition water tank 6 is small, as in the present invention, "the transition water tank 6 employs a small capacity, which is smaller than the capacity of the water source. ". After the design, the required amount for cleaning and using can be better connected, the energy consumption is balanced, and the control program is more beneficial to controlling the opening and closing of the heating element 5, because the larger the capacity of the transition water tank 6 is, the more difficult the stability control on the working temperature is in the dynamic use process, the smaller the capacity of the transition water tank 6 is, and the supply amount can be maintained and supplied, so that the balance point at the moment is more beneficial to balancing the three elements of energy consumption, temperature stability control and cleaning performance.

A labyrinth heating flow passage is arranged in the transition water tank 6 and is used for enabling the heating element 5 to rapidly heat the cleaning liquid flowing through in a short time. In this example, as shown in fig. 7, the labyrinth heating flow path of the transition water tank 6 is provided as a V-shaped labyrinth heating flow path, and the entire outer shape of the transition water tank 6 is also substantially V-shaped in order to better match the rotary cylinder 3.

In this example, as shown in fig. 7, the flow direction of the cleaning liquid in the V-shaped labyrinth heating flow channel is that the cleaning liquid flows in from the right upper end of the V-shaped labyrinth heating flow channel and then flows out from the left upper end of the V-shaped labyrinth heating flow channel along the V-shape, so that after the design, on one hand, the flowing distance is lengthened, so that the cleaning liquid has more time to absorb the heat generated by the heating element 5, and on the other hand, the cleaning liquid flows from bottom to top on the outlet side, and because the heat flows more easily upwards, the cleaning liquid is enabled to better take away the heat generated by the heating element 5. In addition, because the flow channels on the left side and the right side are relatively close due to the V shape, when the heating element 5 heats, the cleaning liquid in the flow channel from the right side to the top is preheated, and when the cleaning liquid flows from the bottom to the top at the outlet side, the cleaning liquid can be heated to a higher temperature more quickly, and the heating time is shortened. In addition, the adoption of the V-shaped labyrinth heating flow passage makes the whole structure very compact. If it is necessary to further shorten the heating time, the heating element 5 may be provided in the flow path from the right side to the top.

After the design, the cleaning liquid in the transition water tank 6 is used for the cleaning part after being heated, long-distance conveying is not needed, waste is greatly reduced, and in addition, potential safety hazards caused by long-distance conveying are avoided.

As shown in fig. 2, 3, 4, 5, 6 and 7, the arrows in fig. 7 indicate the flowing direction of the cleaning liquid, and the cleaning part of the rotary cylinder 3 is heated by the heating part, in this example, specifically, the heating member 5 is disposed around the circumference of the outer periphery of the rotary cylinder 3, the heating member 5 heats the cleaning liquid and also includes a heat conducting member 4, the heat conducting member 4 is disposed around the circumference of the outer periphery of the rotary cylinder 3, and the heating member 5 heats the cleaning part of the rotary cylinder 3 through the heat conducting member 4 while heating the cleaning liquid.

The design has the technical effects that: firstly, the heat generated in the front-rear direction of the heating element 5 can be applied to the cleaning part more quickly, namely the front side of the heating element 5 is the cleaning part, and the rear side of the heating element 5 is the cleaning liquid, so that the heat generated in the front-rear direction of the heating element 5 is more effectively utilized, because the front side of the heating element 5 directly heats the cleaning part, the cleaning liquid in the transition water tank 6 does not need to carry heat to heat the cleaning part, namely one heat conversion is reduced, and the front side of the heating element 5 directly heats the cleaning part has the advantages of improving the structural compactness, and the rear side of the heating element 5 can not directly heat the cleaning part, so that the cleaning part preheated by the front side of the heating element 5 is carried by the cleaning liquid in the transition water tank 6, the heat generated by the heating element 5 is more effectively utilized, and the heating time is very favorable to be shortened, so that the working temperature can be reached in a short period; secondly, while achieving the purpose that heat is more efficiently utilized, it is advantageous to further improve the structural compactness, thereby further reducing the thickness dimension of the transition water tank 6; thirdly, when designing the V-arrangement maze heating runner, only set up heating piece 5 in the runner of V-arrangement maze heating runner left side from bottom to top just can realize faster heating's purpose, and need not all set up heating piece 5 in the left and right sides runner of V-arrangement maze heating runner for overall structure is more optimized, simultaneously, still avoided all setting up the heat waste that heating piece 5 caused in the flow of the left and right sides of V-arrangement maze heating runner like this, because if set up heating piece 5 in the runner of V-arrangement maze heating runner right side top-down, then increase the heat transfer of this heating piece 5 to the right side necessarily, again because the speed that receives cleaning liquid absorption heat, can't absorb in time take away, thereby cause heat loss, and above-mentioned scheme has avoided this kind of situation.

In some embodiments, as shown in fig. 5 and 6, a second opening 10 is provided on the side of the transition water tank 6 facing the rotary cylinder 3, and the second opening 10 is exposed by the heating element 5, so that the blocking between the transition water tank and the heat conducting element 4 is reduced, and the heat transfer of the heating element 5 through the heat conducting element 4 is facilitated. The design can make heating member 5 be close to clean portion more, also makes transition water tank 6 be close to clean portion more simultaneously to make the clean liquid after heating can be carried clean portion by the shorter distance, also make clean portion after heating meet with clean liquid after heating more fast, thereby furthest reduces the loss of heat, makes the less heating power of input, just can keep clean portion's temperature better, that is to say further improves the energy utilization, further promotes response performance simultaneously.

In some embodiments, as shown in fig. 4, 5 and 6, in order to more uniformly output the heated cleaning liquid, a plurality of liquid outlet holes 7 are sequentially provided along the axial direction of the rotary cylinder 3, and the liquid outlet holes 7 communicate with the outlet ends of the V-shaped labyrinth heating flow paths through a plurality of communication holes 8, so that the plurality of liquid outlet holes 7 are located at the upper side of the heat conductive member 4. The liquid inlet end 11 of the V-shaped labyrinth heating runner is communicated with a water source, namely a cleaning liquid tank through a pipeline. A water pump may be provided to increase the delivery pressure of the cleaning liquid. It is also possible to switch off the heating member 5 in time by detecting the water level of the cleaning liquid tank and/or whether the cleaning liquid is present in the pipe, thereby achieving higher safety performance such as dry burning prevention.

In the case of simultaneous heating, other solutions are also possible, for example, the heating element 5 heats the cleaning part of the rotary cylinder 3 directly by the heating element 5 while heating the cleaning liquid, and for example, the heating element 5 heats the cleaning part of the rotary cylinder 3 by the heated transition water tank 6 since the transition water tank 6 heats the cleaning liquid after heating.

When the surface to be cleaned is cleaned or the cleaning part is cleaned, the heating element 5 is kept on, so that the heat of the heating element 5 is utilized to finish the drying and cleaning part.

Embodiment III:

In the third embodiment, the transition water tank 6 is located at the rear side of the scraping plate 12 in the rotation circumferential direction of the rotary cylinder 3, that is, the cleaning portion scrapes the dirt first and then heats the cleaning portion, so that the heat can be more effectively utilized because if the dirty water is not removed by the scraping plate 12 in time, the portion of the cleaning portion where the dirty water is located (the portion of the contaminated cleaning portion) will absorb the heat again, thus causing waste. The polluted cleaning part is unfavorable to sanitation, so the heat is used more effectively by the design, thereby improving sanitation, and in addition, the drying speed is improved when the cleaning part drying program is executed, and waste is further reduced.
