Description

Technical Field

[0001] This invention belongs to the field of heater technology, and specifically relates to a floor scrubber heater used in floor scrubbers. Background Technology

[0002] Floor scrubbers, as cleaning equipment that integrates cleaning and vacuuming, are widely used in household, commercial, and industrial cleaning. To improve cleaning results, some floor scrubbers require heating the cleaning water during the cleaning process, so that the hot water can more effectively dissolve stains, oil, and other deposits. Therefore, the floor scrubber heater has gradually become one of the important functional components of floor scrubbers.

[0003] Existing floor scrubber heaters typically combine a metal water channel structure with an electric heating element to heat the water. These water channel structures are often straight or simply curved, resulting in short water residence times and insufficient heating, leading to low heating efficiency and difficulty in rapidly heating flowing water within a limited space. Furthermore, in some heaters, the thermal contact between the heating element and the water channel structure is insufficient, resulting in low heat transfer efficiency, energy loss, and negatively impacting the overall performance of the machine.

[0004] In addition, the water circuit components of existing floor scrubber heaters are mostly formed by die casting. Although the forming efficiency is high, the die-cast structure is prone to problems such as water leakage and air bursts due to defects such as internal pores and air bubbles during actual use. Especially under heating conditions, the water circuit components are subjected to temperature changes and water pressure impacts, which makes them more prone to sealing failure and insufficient structural reliability, thereby affecting the safety and service life of the product.

[0005] Meanwhile, in existing technologies, water passage covers and water passage components are mostly sealed by adhesive bonding, screwing, or ordinary welding. The reliability of the seal is greatly affected by the assembly process and material aging, and leakage is likely to occur after long-term use.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0007] In view of the technical problems mentioned in the background art, the purpose of this invention is to provide a floor scrubber heater to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a floor scrubber heater, comprising a water channel component, wherein the water channel component has a recessed water channel groove, which is an S-shaped groove; one end of the water channel component has an inlet connector, and the other end of the water channel component has an outlet connector, which are offset from each other at both ends of the water channel component; a thick film heating plate is installed on the lower surface of the water channel component, which is tightly fitted to the water channel component and used to heat the water flowing in the water channel groove; a cover plate groove is recessed in the upper part of the water channel groove, and a sealing cover plate is installed in the cover plate groove, which is sealed to the water channel component to close the water channel groove and form a complete water channel.

[0009] A manufacturing and assembly process for a floor scrubber heater includes the following steps:

[0010] S1. Pure aluminum material is selected as raw material. After heating the aluminum billet to a suitable forging temperature, it is forged into shape through a mold to form a water circuit component forging blank, including water circuit components, water inlet connector and water outlet connector, so that the internal structure of the water circuit component is dense.

[0011] S2. Perform CNC machining on the water channel component, form an S-shaped water channel groove inside the water channel component, form an inlet opening at one end of the water channel groove, form an outlet opening at the other end, and perform precision machining on the flow channel parts of the inlet connector and the outlet connector.

[0012] S3. A thick film mounting surface is formed on the lower surface of the waterway component to give the thick film mounting surface a predetermined flatness and surface finish.

[0013] S4. A cover plate groove is machined in the upper part of the water channel groove for installing a sealing cover plate;

[0014] S5. The thick film heating plate is attached to the thick film mounting surface and fixedly connected to the water circuit components by furnace welding process.

[0015] S6. Install the sealing cover into the groove of the cover, and use laser welding process to circumferentially weld and seal the sealing cover and water circuit components;

[0016] S7. A first heating surface electrical contact part and a second heating surface electrical contact part are formed at both ends of the thick film heating plate to form an electrical connection structure for the thick film heating plate.

[0017] S8. Conduct water flow and power heating tests on the assembled floor scrubber heater. After confirming that the water circuit sealing performance and heating function are normal, the manufacturing of the floor scrubber heater is completed.

[0018] The present invention has the following main advantages: By adopting an integrated forging structure for the water circuit components, inlet and outlet connectors, the overall water circuit structure is dense, with high structural strength and good pressure resistance, effectively avoiding the leakage risk of traditional multi-piece splicing structures and improving safety and reliability; the water circuit groove adopts an S-shaped flow channel design and staggers the inlet and outlet ends, significantly extending the water flow path and heating time in the water circuit, thereby improving heating efficiency and making the outlet water temperature more stable; the thick film heating plate is closely attached to the water circuit components and fixed by welding, with a short heat conduction path and high heat transfer efficiency, enabling rapid heating and reducing energy loss; the water circuit is sealed by welding with a sealing cover plate to form an integrated water circuit structure, with good sealing performance and effectively preventing water leakage; at the same time, the overall structure has a high degree of integration and stable assembly process, suitable for mass production, and can meet the comprehensive needs of floor scrubbers in terms of efficient heating, reliable operation and long-term use.

Detailed Implementation

[0026] like Figures 1 to 6As shown, a floor scrubber heater includes a water channel component 10. The water channel component 10 has an S-shaped water channel groove 11 recessed inside. One end of the water channel component 10 has an inlet connector 12, and the other end has an outlet connector 13. The inlet connector 12 and the outlet connector 13 are offset between the two ends of the water channel component 10, creating a longer flow path for the water within the water channel groove 11, thereby improving the heating time and efficiency of the water. A thick-film heating plate 20 is mounted on the lower surface of the water channel component 10, and is tightly fitted to the water channel component 10. The thick-film heating plate 20 is used to heat the water flowing within the water channel groove 11. The upper part of the water channel groove 11 is recessed with a cover plate groove 14, and a sealing cover plate 30 is installed in the cover plate groove 14. The sealing cover plate 30 is sealed to the water channel component 10 to seal the water channel groove 11 and form a complete water channel to prevent water leakage. In use, the cleaning water enters the water channel groove 11 through the water inlet connector 12. During the flow in the S-shaped water channel groove 11, it fully exchanges heat with the thick film heating plate 20 below to achieve rapid heating of the cleaning water. The heated water flows out through the water outlet connector 13 for use by the floor scrubber, thereby improving the cleaning effect of the floor scrubber.

[0027] In practical implementation, one end of the water channel groove 11 has a water inlet opening 111, and the other end has a water outlet opening 112. The water inlet opening 111 is correspondingly arranged with the water inlet connector 12, and the water outlet opening 112 is correspondingly arranged with the water outlet connector 13, so that water can enter the water channel groove 11 through the water inlet connector 12 and flow out through the water outlet opening 112. In use, the cleaning water enters through the water inlet connector 12 and enters the water channel groove 11 through the water inlet opening 111. The cleaning water flows along the S-shaped water channel groove 11, and in the process of flowing, it fully exchanges heat with the thick film heating plate 20 arranged below, so as to achieve continuous heating of the cleaning water. The heated cleaning water enters the water outlet connector 13 through the water outlet opening 112 and flows out for the cleaning operation of the floor scrubber.

[0028] In practical implementation, the lower surface of the water channel component 10 is provided with a thick film mounting surface 15, and the thick film heating plate 20 is attached to the thick film mounting surface 15 to ensure good thermal conductivity. The surface of the thick film heating plate 20 is provided with a heating panel 21. One end of the heating panel 21 is provided with a first heating surface electrical contact part 211, and the other end of the heating panel 21 is provided with a second heating surface electrical contact part 212. The first heating surface electrical contact part 211 and the second heating surface electrical contact part 212 are staggered at both ends of the heating panel 21 to facilitate power wiring and improve the stability of power-on heating. In use, an external power supply is electrically connected to the first heating surface electrical contact part 211 and the second heating surface electrical contact part 212 respectively, so that the thick film heating plate 20 is powered on and works. The heating panel 21 generates heat, which is quickly transferred to the water channel component 10 through the thick film mounting surface 15, thereby heating the water flowing in the water channel groove 11.

[0029] In practical implementation, one end of the thick film heating plate 20 is provided with a first heating plate through surface 22, and the first heating surface electrical contact part 211 is provided on the first heating plate through surface 22. The other end of the thick film heating plate 20 is provided with a second heating plate through surface 23, and the second heating surface electrical contact part 212 is provided on the second heating plate through surface 23. The first heating surface electrical contact part 211 and the second heating surface electrical contact part 212 are respectively led out from different ends of the thick film heating plate 20, which facilitates electrical connection and installation wiring.

[0030] In specific implementation, the end of the through surface 22 of the first heating plate is provided with a first positioning groove 221, the end of the through surface 23 of the second heating plate is provided with a second positioning groove 231, the rear end of the water inlet connector 12 is provided with a first positioning part 121, and the rear end of the water outlet connector 13 is provided with a second positioning part 131. The first positioning part 121 is embedded in the first positioning groove 221 for positioning, and the second positioning part 131 is embedded in the second positioning groove 231 for positioning, so that the water inlet connector 12 and the water outlet connector 13 respectively form a stable assembly positioning relationship with the thick film heating plate 20, preventing the thick film heating plate 20 from rotating or shifting during installation or use.

[0031] In practical implementation, the manufacturing and assembly process of the floor scrubber heater includes the following steps:

[0032] Step S1: Integrated forging of water system components

[0033] Pure aluminum is selected as the raw material. After the aluminum billet is heated to a suitable forging temperature, it is forged into shape by mold to form a water channel component 10 forging blank, including the water channel component 10, the water inlet connector 12 and the water outlet connector 13. This makes the internal structure of the water channel component 10 dense, avoids the generation of pores and bubbles, and improves the overall strength and pressure resistance.

[0034] Step S2: Fine machining of waterway structure

[0035] The forged water channel component 10 is CNC machined to form an S-shaped water channel groove 11 inside the water channel component 10. A water inlet opening 111 is formed at one end of the water channel groove 11, and a water outlet opening 112 is formed at the other end. At the same time, the flow channels of the water inlet connector 12 and the water outlet connector 13 are precision machined to ensure the dimensional accuracy and smoothness of the water channel.

[0036] Step S3: Thick film mounting surface processing

[0037] A thick film mounting surface 15 is formed on the lower surface of the water channel component 10 by CNC machining, so that the thick film mounting surface 15 has good flatness and surface smoothness, so as to facilitate the bonding and installation of the thick film heating plate 20 and improve the heat conduction efficiency.

[0038] Step S4: Fabrication of the cover plate installation structure

[0039] A cover plate groove 14 is machined on the upper part of the water channel groove 11 for installing a sealing cover plate 30, so that the water channel groove 11 forms a closed water channel structure after subsequent assembly.

[0040] Step S5: Thick film heating plate installation and furnace welding connection

[0041] The thick film heating plate 20 is attached to the thick film mounting surface 15 and fixedly connected to the water circuit component 10 by furnace welding process, so that a stable welding layer is formed between the thick film heating plate 20 and the water circuit component 10, ensuring good thermal conductivity and connection reliability.

[0042] Step S6: Installation of sealing cover and laser welding sealing

[0043] The sealing cover 30 is installed into the cover groove 14, and the sealing cover 30 and the water circuit component 10 are circumferentially welded and sealed using laser welding technology to form a continuous and dense weld seam to prevent water leakage from the water circuit component 10 during use.

[0044] Step S7: Formation of electrical connection structure

[0045] The first heating surface contact part 211 and the second heating surface contact part 212 are respectively led out from the first heating plate through surface 22 and the second heating plate through surface 23 of the thick film heating plate 20, and the electrical terminals are formed or assembled to enable the thick film heating plate 20 to have stable power-on heating conditions.

[0046] Step S8: Overall verification and assembly completion

[0047] After the assembled floor scrubber heater is tested for water flow and power supply, and the water circuit sealing performance and heating function are confirmed to meet the usage requirements, the manufacturing of the floor scrubber heater is completed.
