Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically a heating structure for a window cleaning machine and the window cleaning machine itself. Background Technology

[0002] Among modern cleaning equipment, window cleaning machines are widely used in high-rise building glass cleaning and industrial equipment surface cleaning due to their high efficiency and convenience. However, when using window cleaning machines in cold or low-temperature environments, the temperature of the cleaning fluid is low, and its ability to dissolve dirt is significantly reduced, especially for grease or stubborn stains. In addition, low-temperature liquids may cause frost or ice to form on the glass surface, further affecting the cleaning efficiency.

[0003] Existing window cleaning machines heat the cleaning fluid using external heating devices, but these devices often suffer from low heat transfer efficiency and uneven heating, resulting in localized overheating or incomplete heating of the liquid during the heating process, which affects the cleaning effect and equipment stability.

[0004] Therefore, it is necessary to develop a heating structure and a window cleaning machine to solve the problems of low heat transfer efficiency and uneven heating of existing window cleaning machine heating devices. Utility Model Content

[0005] To address the aforementioned problems of low heat transfer efficiency and uneven heating in existing window cleaning machines, the technical solution adopted by this utility model is as follows:

[0006] A heating structure for a window cleaning machine includes a heating device. The heating device has a heating chamber, a water inlet and a water outlet respectively communicating with the heating chamber. The water inlet and the water outlet are respectively located at the upper and lower ends of the heating device. The heating device also has a heat-conducting part extending into the heating chamber. The heat-conducting part has an installation cavity for installing a heating element. The heating element is installed in the installation cavity to heat the liquid in the heating chamber.

[0007] Furthermore, the central axis of the heat-conducting part coincides with the central axis of the heating cavity, so that the heating cavity forms an annular heating space.

[0008] Furthermore, the water outlet is provided with a water outlet channel communicating with the heating chamber, and the water inlet is provided with a water inlet channel communicating with the heating chamber, wherein the diameter of the water inlet channel is larger than the diameter of the water outlet channel.

[0009] Furthermore, the heating structure of the window cleaning machine includes a fixing sleeve, which has a fixing cavity for installing the heating device and a plurality of fixing parts for connecting to the outside.

[0010] Furthermore, the heating structure of the window cleaning machine includes a heat insulation layer, which is sleeved on the outside of the heating device and installed together with the heating device in the fixed cavity.

[0011] Furthermore, the lower part of the inner side of the fixing sleeve is provided with multiple abutment blocks to form a limiting part that restricts the insertion depth of the heating device and the heat insulation layer.

[0012] Furthermore, the fixing sleeve is made of soft material, and the fixing sleeve has at least two heat dissipation windows on its side.

[0013] Furthermore, the heating device includes a first heating component and a second heating component connected to the first heating component. The heating chamber and the water outlet are located in the first heating component, and the water inlet and the heat-conducting part are located in the second heating component. The first heating component and the second heating component are connected by a threaded connection.

[0014] Furthermore, a sealing ring is provided at the threaded connection between the first heating component and the second heating component.

[0015] A window cleaning machine, including the heating structure of the window cleaning machine.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention improves heating efficiency by incorporating a heat-conducting part that extends into the heating chamber and a mounting cavity for the heating element within the heat-conducting part. This allows the heating element to extend into the mounting cavity and rapidly transfer heat to the liquid through the heat-conducting part. Furthermore, by placing the water inlet at the lower end of the heating device and the water outlet at the upper end, a water pump injects liquid into the heating chamber from the water inlet at the lower end of the heating device. As the water pump continuously injects liquid, it flows upwards, extending the heating time and ensuring that the liquid is fully heated. Attached Figure Description

[0027] Please see Figures 1 to 6 The heating structure of a window cleaning machine shown includes a heating device 1. The heating device 1 has a heating chamber 11, a water inlet 12 and a water outlet 13 respectively communicating with the heating chamber 11. The water inlet 12 and the water outlet 13 are respectively located at the upper end and the lower end of the heating device 1. The heating device 1 also has a heat-conducting part 14 extending into the heating chamber 11. The heat-conducting part 14 has an installation cavity 141 for installing a heating element. The heating element is installed in the installation cavity 141 to heat the liquid in the heating chamber 11.

[0028] In this invention, the heating device 1 is provided with a heating chamber 11, a water inlet 12, a water outlet 13, and a heat-conducting part 14. The heating chamber 11 is used to contain liquid, and the heat-conducting part 14 is used to install a heating element and extends directly into the heating chamber 11 to transfer the heat from the heating element to the liquid in the heating chamber 11. This effectively improves the efficiency of the process, allowing the liquid to flow from the water inlet 12 into the heating chamber 11 and out through the water outlet 13 after heating. Specifically, the water inlet 12 is located at the lower end of the heating device 1, and the water outlet 13 is located at the upper end. This means that the liquid enters the heating chamber 11 from the lower end. As the water pump continuously injects liquid into the heating chamber 11, the liquid gradually flows from the lower end to the upper end, resulting in a longer residence time of the liquid in the heating chamber 11. This extends the time for heat exchange between the liquid and the heat-conducting part 14, effectively improving the heating efficiency and ensuring that the liquid is fully heated.

[0029] Furthermore, the central axis of the heat-conducting part 14 coincides with the central axis of the heating cavity 11, so that the heating cavity 11 forms an annular heating space.

[0030] In this invention, the central axis of the heat-conducting part 14 coincides with the central axis of the heating cavity 11, so that the heating cavity 11 forms an annular heating space. This means that the heat-conducting part 14 is located at the center of the heating cavity 11, and the heating cavity 11 forms an annular space around the heat-conducting part 14. The liquid flows in the annular space. This design allows the liquid to be evenly distributed around the heat-conducting part 14, maximizing the contact area between the liquid and the heat-conducting part 14. This ensures that the heat from the heat-conducting part 14 can be evenly transferred to the liquid, avoiding the problems of local overheating or incomplete heating that may exist in traditional heating methods. At the same time, it makes the heating structure more compact and easier to integrate into a window cleaning machine.

[0031] Furthermore, the water outlet 13 is provided with a water outlet channel 131 communicating with the heating chamber 11, and the water inlet 12 is provided with a water inlet channel 121 communicating with the heating chamber 11. The diameter of the water inlet channel 121 is larger than the diameter of the water outlet channel 131.

[0032] In this invention, the diameter of the inlet channel 121 is larger than the diameter of the outlet channel 131. The larger diameter of the inlet channel 121 ensures that the liquid can quickly enter the heating chamber 11, avoiding a decrease in heating efficiency due to insufficient flow. The smaller diameter of the outlet channel 131 limits the outflow speed of the liquid, preventing unheated liquid from flowing out prematurely. A certain back pressure is formed in the heating chamber 11, further extending the heating time of the heat-conducting part 14 on the liquid, ensuring that the liquid is fully heated to the target temperature.

[0033] Furthermore, the heating structure includes a fixing sleeve 2, which has a fixing cavity 21 for mounting the heating device 1 and a plurality of fixing parts 22 for connecting to the outside.

[0034] In this utility model, the fixing sleeve 2 is a component used to fix the heating device 1 to the window cleaning machine. The fixing cavity 21 is a cavity in the fixing sleeve 2 used to install and fix the heating device 1. Further, the fixing part 22 is a part in the fixing sleeve 2 that connects to the window cleaning machine. Multiple fixing parts 22 are distributed on the outside of the fixing sleeve 2 to connect the entire structure with other components of the window cleaning machine. Specifically, the fixing part 22 can take the form of threaded hole, snap buckle or flange, etc., to facilitate quick assembly and disassembly with other components.

[0035] Furthermore, the heating structure includes a heat insulation layer 3, which is sleeved on the outside of the heating device 1 and installed together with the heating device 1 in the fixed cavity 21.

[0036] In this invention, the heat insulation layer 3 is tightly fitted onto the outside of the heating device 1 and is installed together with the heating device 1 as an integral module in the fixed cavity 21. Furthermore, the heat insulation layer 3 can be made of high-efficiency heat insulation materials, such as aluminum silicate fiber, aerogel, or polyurethane foam. These materials have low thermal conductivity and good high-temperature resistance. By wrapping the heat insulation layer 3 around the outside of the heating device 1, heat loss to the external environment can be effectively prevented, ensuring that heat is concentrated and transferred to the liquid in the heating cavity 11, effectively improving heating efficiency and reducing energy consumption. At the same time, the heat insulation layer 3 also plays an isolation role, preventing the heat generated by the heating device 1 from causing thermal damage to other components of the window cleaning machine, effectively improving the safety and reliability of the structure.

[0037] Furthermore, the lower part of the inner side of the fixing sleeve 2 is provided with a plurality of abutment blocks 231, forming a limiting part 23 that restricts the insertion depth of the heating device 1 and the heat insulation layer 3.

[0038] In this invention, the abutment blocks 231 are evenly distributed on the lower part of the inner side of the fixing sleeve 2, forming the limiting part 23, to ensure that the heating device 1 and the heat insulation layer 3 can be stably supported. The limiting part 23 formed by the abutment blocks 231 restricts the insertion depth of the heating device 1 and the heat insulation layer 3 in the fixing cavity 21. This design ensures that the heating device 1 and the heat insulation layer 3 are not over-inserted during installation, avoiding the heating device 1 from falling out of the heating cavity 11 due to positional deviation, and effectively improving the connection stability and reliability of the heating device 1 and the fixing sleeve 2.

[0039] Furthermore, the fixing sleeve 2 is made of soft material, and the fixing sleeve 2 has at least two heat dissipation windows 24 on its side.

[0040] In this invention, the fixing sleeve 2 is made of soft material, such as silicone, rubber or flexible polyurethane. These materials have a certain degree of flexibility and elasticity, while meeting the high temperature resistance requirements of the heating device 1. The soft material can effectively absorb the vibration generated during the operation of the window cleaning machine, reduce the impact of the external environment on the heating device 1, and effectively improve the overall stability of the equipment. Furthermore, the fixing sleeve 2 is provided with a heat dissipation window 24 on its side to help the excess heat generated by the heating device 1 dissipate quickly and prevent heat from accumulating in the fixing cavity 21.

[0041] As a preferred embodiment of the present invention and not a limitation thereof, the heat dissipation window 24 is provided in two and symmetrically arranged on the side of the fixing sleeve 2. This symmetrical arrangement ensures that heat can be dissipated evenly and avoids the problem of uneven temperature distribution caused by heat dissipation on one side.

[0042] Furthermore, the heating device 1 includes a first heating component 15 and a second heating component 16 connected to the first heating component 15. The heating chamber 11 and the water outlet 13 are located in the first heating component 15, and the water inlet 12 and the heat conduction part 14 are located in the second heating component 16. The first heating component 15 and the second heating component 16 are connected by a threaded connection.

[0043] In this utility model, the heating device 1 is divided into a first heating component 15 and a second heating component 16. The heating chamber 11 and the water outlet are located in the first heating component 15, and the water inlet 12 and the heat conduction part 14 are located in the second heating component 16. This means that the heating device 1 is divided into two modules. The first heating component 15 and the second heating component 16 are connected by a threaded connection, which makes the heating device 1 easy to manufacture and maintain. Users can disassemble the heating device 1 and clean the heating chamber 11, which effectively improves the convenience of maintenance of the heating structure.

[0044] Furthermore, a sealing ring 17 is provided at the threaded connection between the first heating component 15 and the second heating component 16.

[0045] In this invention, a sealing ring 17 is provided at the threaded connection between the first heating component 15 and the second heating component 16. Since the heating device 1 is divided into two modules, the first heating component 15 and the second heating component 16, the sealing ring 17 ensures the sealing of the heating cavity 11 in order to ensure the sealing of the connection between the first heating component 15 and the second heating component 16. During assembly, the sealing ring 17 is compressed at the threaded connection between the first heating component 15 and the second heating component 16, and achieves a tight fit through elastic deformation to ensure the sealing of the heating cavity 11. In addition, the elastic deformation of the sealing ring 17 can absorb some vibration and impact, further enhancing the overall stability of the heating structure.

[0046] A window cleaning machine, including the heating structure of the window cleaning machine.

[0047] The window cleaning machine of this utility model integrates the heating structure of the window cleaning machine, realizing efficient and uniform heating of cleaning liquid and stable equipment operation. The cleaning liquid enters the heating chamber 11 from the water inlet 12 of the heating device 1 through the water pump. The heating tube installed in the mounting chamber 141 heats the cleaning liquid in the heating chamber 11 through the heat conduction part 14. The heated cleaning liquid flows out from the water outlet 13 and is delivered to the nozzle, and is evenly sprayed onto the glass surface. The high temperature enhances the dissolving ability and quickly softens the dirt, effectively improving the dirt cleaning ability of the window cleaning machine.

[0048] As a preferred embodiment of this utility model and not a limitation thereof, the heating element has a power of 20W and a voltage of 24V. The heat generated by the heating element heats the liquid in the heating chamber 11 to 50-70℃. The liquid in this temperature range can promote the softening and dissolution of stains on the glass surface. Compared with a high-power heating element that heats the liquid to boiling or steam, this method can reduce the energy consumption of the heating element while maintaining a certain stain softening effect, effectively improving the practicality and reliability of the window cleaning machine.
