Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a heating component and cleaning equipment. Background Technology

[0002] In related technologies, cleaning equipment has hot water and steam modes. In hot water mode, the roller brush removes stains and grease more easily under the influence of hot water; in steam mode, stubborn dirt on the floor is softened and removed more easily under the high temperature of steam. However, the heating components of current cleaning equipment can only produce either hot water or only steam. When both the roller brush and the floor need to be cleaned, they must be cleaned separately, which is inefficient. Utility Model Content

[0003] In view of this, embodiments of this application provide a heating component and a cleaning device to solve the problem that current heating components cannot simultaneously produce hot water and steam.

[0004] The first aspect of this application discloses a heating assembly, comprising:

[0005] A heater includes a housing and a heating element. The housing has a first flow channel and a second flow channel. The housing has a hot water outlet communicating with the first flow channel and a steam outlet communicating with the second flow channel. The housing also has a water inlet communicating with the first flow channel and the second flow channel. The heating element is disposed inside the housing and is used to heat water in the first flow channel into hot water and / or heat water in the second flow channel into steam.

[0006] Water inlet pipe, connected to the water inlet;

[0007] A flow control valve is installed on the water inlet pipe. When water flows simultaneously in the first flow channel and the second flow channel, the flow control valve is used to control the flow rate of the second flow channel to be less than the flow rate of the first flow channel.

[0008] The beneficial effects of the heating assembly provided in this application embodiment are as follows: In use, water in the inlet pipe enters the first flow channel and the second flow channel through the inlet. A flow control valve installed on the inlet pipe controls the flow rate of the second flow channel to be less than that of the first flow channel. Understandably, the water flow rate in the first flow channel is larger, and the water in the first flow channel is heated by the heating element to become hot water, which flows out from the hot water outlet. Conversely, the flow rate in the second flow channel is smaller, and the water in the second flow channel is heated by the heating element to become steam, which flows out from the steam outlet. That is, by setting the first and second flow channels within the housing, the above-mentioned heating assembly can simultaneously produce hot water and steam, solving the problem that current heating assemblies cannot simultaneously produce hot water and steam.

[0009] Of course, you can also choose to produce only hot water or only steam, depending on your needs.

[0010] In some embodiments, the housing includes an outer shell and a thermally conductive inner shell disposed within the outer shell, the thermally conductive inner shell dividing the inner cavity of the outer shell into a first flow channel and a second flow channel, and the heating element being located within the thermally conductive inner shell.

[0011] In some embodiments, a plurality of first ribs and a plurality of second ribs are respectively provided on two opposite inner wall surfaces of the outer shell. The heat-conducting inner shell, the plurality of first ribs and the outer shell together form a zigzag-shaped first flow channel, and the heat-conducting inner shell, the plurality of second ribs and the outer shell together form a zigzag-shaped second flow channel.

[0012] In some embodiments, the thermally conductive inner shell is retractably mounted between a plurality of first ribs and a plurality of second ribs.

[0013] In some embodiments, a first sealing ring is provided between the heat-conducting inner shell and the outer shell, the first sealing ring being used to prevent water from flowing between the first flow channel and the second flow channel.

[0014] In some embodiments, at least two first sealing rings are provided, with at least one first sealing ring located between the heating element and the first flow channel, and at least one first sealing ring located between the heating element and the second flow channel.

[0015] In some embodiments, the number of the second ribs is greater than the number of the first ribs.

[0016] In some embodiments, the heating element includes a first heating element and a second heating element arranged in a stacked manner, wherein the first heating element is used to heat the water flow in the first flow channel into hot water, and the second heating element is used to heat the water flow in the second flow channel into steam.

[0017] In some embodiments, the water flow rate in the first channel is 60-100 ml / min; and / or, the water flow rate in the second channel is 0-40 ml / min.

[0018] In some embodiments, the water inlet includes a first water inlet and a second water inlet, wherein the first water inlet is connected to the first flow channel and the second water inlet is connected to the second flow channel.

[0019] In some embodiments, the flow control valve is a proportional valve, and the inlet pipe includes a main pipe, a first branch pipe, and a second branch pipe. The main pipe is connected to the first branch pipe and the second branch pipe through the proportional valve. The first branch pipe is connected to the first inlet, and the second branch pipe is connected to the second inlet.

[0020] In some embodiments, the heating element is a heating element, a heating plate, or a heating wire.

[0021] In some embodiments, the housing includes a housing body and a cover plate. The housing body has a first side and a second side arranged opposite to each other. The first side is a closed structure, and the first water inlet, the second water inlet, the hot water outlet and the steam outlet are located on the first side of the housing body. The second side is an open structure, and the cover plate is detachably connected to the housing body and covers the second side.

[0022] In some embodiments, the cover plate is provided with a boss, and a second sealing ring is provided between the boss and the outer shell body.

[0023] The second aspect of this application provides a cleaning device that includes a heating component as described in the first aspect.

[0024] The cleaning device employs any one or more embodiments of the heating components described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.

[0059] An embodiment of the first aspect of this application provides a heating component for use in a cleaning device, which may be a floor scrubber, such as a handheld floor scrubber.

[0060] Please refer to Figures 1 to 3 The heating assembly 100 includes a heater 10, a water inlet pipe 20, and a flow control valve 30. The heater 10 includes a housing 11 and a heating element 12. The housing 11 has a first flow channel 11117 and a second flow channel 11118. The housing 11 is provided with a hot water outlet 11112 communicating with the first flow channel 11117 and a steam outlet 11114 communicating with the second flow channel 11118. The housing 11 is also provided with a water inlet communicating with the first flow channel 11117 and the second flow channel 11118. The heating element 12 is disposed inside the housing 11 and is used to heat the water in the first flow channel 11117 into hot water and / or heat the water in the second flow channel 11118 into steam.

[0061] The shell 11 has a first flow channel 11117 and a second flow channel 11118. Understandably, the first flow channel 11117 and the second flow channel 11118 are arranged independently, that is, the water flow in the first flow channel 11117 and the second flow channel 11118 does not interfere with each other.

[0062] For example, the water inlet may include a first water inlet 11111 and a second water inlet 11113. That is, water flows through the first water inlet 11111 into the first flow channel 11117, and is heated into hot water while flowing in the first flow channel 11117, and finally flows out from the hot water outlet 11112; water flows through the second water inlet 11113 into the second flow channel 11118, and is heated into steam while flowing in the second flow channel 11118, and finally flows out from the steam outlet 11114. Of course, only one water inlet may be provided, and the housing 11 may also have two diversion channels, through which water from the water inlet enters the first flow channel 11117 and the second flow channel 11118 respectively.

[0063] The heating element 12 is disposed inside the housing 11. After the heating element 12 is energized, it generates heat and transfers the heat to the water flow in the first flow channel 11117 and / or the second flow channel 11118. This can be understood as follows: when there is water flow in the first flow channel 11117, the heating element 12 heats the water flowing in the first flow channel 11117 into hot water; or, when there is water flow in the second flow channel 11118, the heating element 12 heats the water flowing in the second flow channel 11118 into steam; or, when there is water flow in both the first flow channel 11117 and the second flow channel 11118, the heating element 12 heats the water flowing in the first flow channel 11117 into hot water and simultaneously heats the water flowing in the second flow channel 11118 into steam.

[0064] It is understood that the heating element 12 can be a heating plate, heating element, or heating element. When the heating element 12 is a heating element, the heating element 12 is a PTC (Positive Temperature Coefficient) heating core.

[0065] The inlet pipe 20 is connected to the inlet. Understandably, the water in the inlet pipe 20 can enter the first flow channel 11117 and the second flow channel 11118 through the inlet.

[0066] A flow control valve 30 is installed on the inlet pipe 20. When water flows simultaneously in the first flow channel 11117 and the second flow channel 11118, the flow control valve 30 controls the flow rate in the second flow channel 11118 to be less than the flow rate in the first flow channel 11117. In this way, the smaller water flow rate in the second flow channel 11118 is conducive to the formation of steam from the water in the second flow channel 11118; the larger water flow rate in the first flow channel 11117 is conducive to the formation of hot water from the water in the second flow channel 11118.

[0067] The beneficial effects of the heating assembly 100 provided in this application embodiment are as follows: In use, water in the inlet pipe 20 enters the first flow channel 11117 and the second flow channel 11118 through the inlet. The flow control valve 30 installed on the inlet pipe 20 controls the flow rate of the second flow channel 11118 to be less than the flow rate of the first flow channel 11117. Understandably, the water flow rate in the first flow channel 11117 is larger, and the water in the first flow channel 11117 is heated by the heating element 12 to become hot water, which flows out from the hot water outlet 11112. Conversely, the flow rate in the second flow channel 11118 is smaller, and the water in the second flow channel 11118 is heated by the heating element 12 to become steam, which flows out from the steam outlet 11114. That is, by providing the first flow channel 11117 and the second flow channel 11118 within the housing 11, the heating assembly 100 can simultaneously produce hot water and steam, solving the problem that current heating assemblies 100 cannot simultaneously produce hot water and steam.

[0068] Of course, as needed, the water in the inlet pipe 20 can be made to enter only the first flow channel 11117, that is, only hot water is produced; or, the water in the inlet pipe 20 can be made to enter only the second flow channel 11118, that is, only steam is produced.

[0069] Please refer to Figure 3 In some embodiments, the housing 11 includes an outer shell 111 and a heat-conducting inner shell 112 disposed within the outer shell 111. The heat-conducting inner shell 112 divides the inner cavity of the outer shell 111 into a first flow channel 11117 and a second flow channel 11118. The heating element 12 is located within the heat-conducting inner shell 112.

[0070] The heat-conducting inner shell 112 is a metal inner shell, such as an aluminum shell, copper shell, or iron shell, to facilitate heat transfer.

[0071] For example, the heat-conducting inner shell 112 is in the shape of a rectangular ring, and correspondingly, the heating element 12 is in the shape of a rectangle.

[0072] It is understood that the first flow channel 11117 and the second flow channel 11118 can be located on the upper and lower sides of the heat-conducting inner shell 112; or, the first flow channel 11117 and the second flow channel 11118 can also be located on the left and right sides of the heat-conducting inner shell 112.

[0073] Based on the above technical solution, the water flowing in the first flow channel 11117 and the second flow channel 11118 can be heated by the same heating element 12, which is beneficial to improving the structural compactness of the heater 10.

[0074] In other embodiments, the heat-conducting inner shell 112 may not be provided, the outer shell 111 may be a metal shell, the heating element 12 may be disposed in the side wall of the outer shell 111, and the structure of the outer shell 111 itself may separate the first flow channel 11117 and the second flow channel 11118.

[0075] Please refer to Figure 3 In some embodiments, a plurality of first ribs 11115 and a plurality of second ribs 11116 are respectively provided on two opposite inner wall surfaces of the outer shell 111. The heat-conducting inner shell 112, the plurality of first ribs 11115 and the outer shell 111 together form a zigzag-shaped first flow channel 11117, and the heat-conducting inner shell 112, the plurality of second ribs 11116 and the outer shell 111 together form a zigzag-shaped second flow channel 11118.

[0076] It is understandable that the first rib 11115 can be along... Figure 3 Two, three, four, or five or more ribs can be set at intervals in the left and right directions; the second rib 11116 can be along... Figure 3 The left and right directions can be spaced two, three, four, or five or more.

[0077] The heat-conducting inner shell 112, multiple first ribs 11115, and outer shell 111 together form a zigzag-shaped first flow channel 11117. Please refer to [reference needed]. Figure 4 Water enters the first flow channel 11117 through the first inlet 11111, flows back and forth within the first flow channel 11117, and finally flows out from the hot water outlet 11112. This increases the flow time of the water within the first flow channel 11117, ensuring that the water in the first flow channel 11117 can be heated to the required temperature.

[0078] The heat-conducting inner shell 112, multiple second ribs 11116, and outer shell 111 together form a zigzag-shaped second flow channel 11118. Please refer to [reference needed]. Figure 5 Water enters the second flow channel 11118 through the second inlet 11113, flows back and forth within the second flow channel 11118, and finally flows out from the steam outlet 11114. This increases the flow time of the water within the second flow channel 11118, ensuring that the water in the second flow channel 11118 can be heated into steam.

[0079] Based on the above technical solution, by designing the first flow channel 11117 and the second flow channel 11118 as a broken line, the length of the heater 10 is relatively short while increasing the flow time of water in the first flow channel 11117 and the second flow channel 11118, which is beneficial to the arrangement of the heater 10 in the cleaning equipment.

[0080] Please refer to Figures 7 to 9 In some embodiments, the heat-conducting inner shell 112 is retractably mounted between a plurality of first ribs 11115 and a plurality of second ribs 11116.

[0081] Understandably, the upper and lower sides of the heat-conducting inner shell 112 are limited by the first protrusion 11115 and the second protrusion 11116, and the left and right sides of the heat-conducting inner shell 112 are limited by the side wall of the outer shell body 1111, so that the heat-conducting inner shell 112 can only move in the pulling direction.

[0082] Based on the above technical solution, by removably installing the heat-conducting inner shell 112 between multiple first protrusions 11115 and multiple second protrusions 11116, it is beneficial to install the heat-conducting inner shell 112.

[0083] In some embodiments, a first sealing ring is provided between the heat-conducting inner shell 112 and the outer shell 111. The first sealing ring is used to prevent water in the first flow channel 11117 and the second flow channel 11118 from flowing to each other.

[0084] For example, the outer peripheral surface of the heat-conducting inner shell 112 is provided with a first sealing groove 1121, and a first sealing ring is disposed in the first sealing groove 1121. Of course, the first sealing groove 1121 can also be disposed on the inner wall surface of the outer shell 111.

[0085] Understandably, the first sealing ring can be located between the heating element 12 and the first flow channel 11117, or between the heating element 12 and the second flow channel 11118, to prevent the water in the first flow channel 11117 and the second flow channel 11118 from flowing to each other.

[0086] In some embodiments, at least two first sealing rings are provided, with at least one first sealing ring located between the heating element 12 and the first flow channel 11117, and at least one first sealing ring located between the heating element 12 and the second flow channel 11118.

[0087] It is understandable that the first sealing ring can be set in three, four, or five or more.

[0088] For example, two first sealing rings are provided, and correspondingly, two first sealing grooves 1121 are provided on the outer periphery of the heat-conducting inner shell 112. One first sealing groove 1121 is located below the heating element 12, that is, the first sealing groove 1121 is located between the heating element 12 and the first flow channel 11117; the other first sealing groove 1121 is located above the heating element 12, that is, the first sealing groove 1121 is located between the heating element 12 and the second flow channel 11118. After the heat-conducting inner shell 112 is installed inside the outer shell 111, the two first sealing rings can prevent the circuit and the heating element 12 from being affected by water in the first flow channel 11117 and the second flow channel 11118.

[0089] In other embodiments, the thermally conductive inner shell 112 can be fixed inside the outer shell 111 by adhesive bonding. For example, the thermally conductive inner shell 112 can be fixed inside the outer shell 111 by adhesive bonding, achieving both fixation and sealing.

[0090] In some embodiments, one end of the thermally conductive inner shell 112 is closed and the other end has an opening, and the heating element 12 is inserted into the thermally conductive inner shell 112 through the opening.

[0091] Please refer to Figure 4 and Figure 5 In some embodiments, the number of second ribs 11116 is greater than the number of first ribs 11115.

[0092] By adopting the above technical solution, the total length of the second flow channel 11118 is greater than the total length of the first flow channel 11117, which is beneficial to prolong the flow time of water in the second flow channel 11118, thereby facilitating the heating of water into steam.

[0093] Please refer to Figure 3 In some embodiments, the heating element 12 includes a first heating element 121 and a second heating element 122 arranged in layers. The first heating element 121 is used to heat the water flow in the first flow channel 11117 into hot water, and the second heating element 122 is used to heat the water flow in the second flow channel 11118 into steam.

[0094] By adopting the above technical solution, the first heating element 121 and the second heating element 122 respectively heat the water in the first flow channel 11117 and the second flow channel 11118. When energized, the current supplied to the second heating element 122 can be greater than the current supplied to the first heating element 121, which is beneficial for the first heating element 121 to heat the water flow in the first flow channel 11117 into hot water, and for the second heating element 122 to heat the water flow in the second flow channel 11118 into steam.

[0095] In other embodiments, only one first heating element 121 or a second heating element 122 may be provided.

[0096] In some embodiments, the housing 111 is a heat-insulating housing.

[0097] For example, the housing 111 is a plastic housing.

[0098] By adopting the above technical solution, when the heating body 12 heats the water in the first flow channel 11117 and / or the second flow channel 11118, heat loss can be reduced, which is beneficial to improving heating efficiency.

[0099] In other embodiments, the housing 111 may be a metal housing.

[0100] In some embodiments, when water flows simultaneously in the first flow channel 11117 and the second flow channel 11118, the flow control valve 30 controls the flow rate of the second flow channel 11118 to be less than the flow rate of the first flow channel 11117. For example, the flow rate of water in the first flow channel 11117 is 60-100 ml / min, and the flow rate of water in the second flow channel 11118 is 0-40 ml / min.

[0101] It is understandable that the flow rate of water in the first flow channel 11117 can be 60ml / min, 70ml / min, 80ml / min, 90ml / min or 100ml / min, etc.

[0102] It is understandable that the water flow rate in the second flow channel 11118 can be 5ml / min, 10ml / min, 20ml / min, 30ml / min or 40ml / min, etc.

[0103] For example, when the heating assembly 100 is working, the drive pump 40 starts, and the water heater 10 with a power of 300W is powered on. Water at a temperature of 25°C and a flow rate of 80ml / min enters the first flow channel 11117 through the first inlet 11111. The water in the first flow channel 11117 comes into contact with the heat-conducting inner shell 112. During its flow in the first flow channel 11117, the water absorbs the heat transferred by the heat-conducting inner shell 112 and finally flows out from the hot water outlet 11112 with hot water at approximately 80°C. Water at a temperature of 25°C and a flow rate of 10ml / min enters the second flow channel 11118 through the second inlet 11113. The water in the second flow channel 11118 comes into contact with the heat-conducting inner shell 112. During its flow in the second flow channel 11118, the water absorbs the heat transferred by the heat-conducting inner shell 112 and is heated into steam, which finally flows out from the steam outlet 11114.

[0104] Please refer to Figure 1 In some embodiments, based on the case where the water inlet includes a first water inlet 11111 and a second water inlet 11113, the flow control valve 30 is a proportional valve, and the water inlet pipe 20 includes a main pipe 21, a first branch pipe 22 and a second branch pipe 23. The main pipe 21 is connected to the first branch pipe 22 and the second branch pipe 23 through the proportional valve. The first branch pipe 22 is connected to the first water inlet 11111, and the second branch pipe 23 is connected to the second water inlet 11113.

[0105] Based on the above technical solution, by controlling the proportional valve, the proportion of water entering the first branch pipe 22 and the second branch pipe 23 in the main pipe 21 can be controlled, which is beneficial to controlling the hot water temperature at the hot water outlet 11112 and the steam volume at the steam outlet 11114.

[0106] In other embodiments, please refer to Figure 11The flow control valve 30 includes a first control valve 31 and a second control valve 32. The first control valve 31 is located on the first branch pipe 22 to control the flow rate of water entering the first flow channel 11117. The second control valve 32 is located on the second branch pipe 23 to control the flow rate of water entering the second flow channel 11118. For example, the first control valve 31 and the second control valve 32 can be solenoid valves.

The second side is an open structure, and the cover plate 1112 is detachably connected to the outer casing body 1111 and covers the second side.

[0108] For example, the cover plate 1112 can be fixedly connected to the housing body 1111 by threaded fasteners. The threaded fasteners can be screws, bolts, etc.

[0109] In some embodiments, please refer to Figure 10 The cover plate 1112 is provided with a boss 11121, and a second sealing ring is provided between the boss 11121 and the outer shell body 1111.

[0110] For example, a boss 11121 is provided on the side of the cover plate 1112 facing the outer shell body 1111, and a second sealing groove 11122 is provided on the side of the boss 11121, with a second sealing ring installed in the second sealing groove 11122. When the cover plate 1112 is fixedly connected to the outer shell body 1111, the boss 11121 is inserted into the second side of the outer shell body 1111, and the second sealing ring seals the connection between the cover plate 1112 and the outer shell body 1111, preventing water in the first flow channel 11117 and the second flow channel 11118 from flowing to the outside of the outer shell 111. Of course, the second sealing groove 11122 can also be provided on the inner wall surface of the outer shell body 1111.

[0111] In some embodiments, please refer to Figure 6 The heating assembly 100 also includes a positive electrode 50 and a negative electrode 60, which are disposed on the cover plate 1112. When the cover plate 1112 is fixedly connected to the outer casing 1111, the positive electrode 50 and the negative electrode 60 are electrically connected to the heating element 12.
