Description

Technical Field

[0001] The utility model belongs to the technical field of carpet cleaning equipment, and in particular relates to a high-temperature carpet cleaning machine which can be quickly disassembled and has energy recovery. Background Art

[0002] Carpet, fabric, and floor cleaning are widely used in hotels, guesthouses, cleaning services, and homes. However, commercial carpet cleaning machines used in these areas are often bulky, non-detachable, or can only be disassembled one layer, making them difficult to quickly reassemble. Loading and unloading the machine requires two or more people. For small or large areas, a single person could handle the job, but the lack of quick disassembly increases labor and time costs. Furthermore, for buildings without elevators, the bulk and inability to quickly disassemble existing commercial carpet cleaning machines make moving up and down stairs inconvenient, and also increases the need for additional manpower. In terms of product design, traditional electric heated carpet cleaning machines face power constraints, especially in countries with 110V voltage. This low voltage prevents the use of higher-power appliances, limits the temperature generated by the heating element, and generates significant heat from the fan, leading to high casing temperatures. This not only shortens the fan's lifespan, but also creates significant waste due to the lack of heat recovery, failing to achieve energy conservation and environmental protection, and thus extending product lifespan. The above discussion discusses the development of traditional electric heated carpet cleaning mechanisms, focusing on carpet cleaning equipment technology and reducing labor costs to conserve energy and improve product lifespan. Therefore, this plan specifically proposes a high-temperature carpet cleaning machine with strong suction power for cleaning carpets and floors, which can be quickly disassembled and easily carried. In particular, it is a high-temperature and high-pressure carpet cleaning equipment with energy recovery, energy saving and environmental protection, which can effectively increase the life of fan accessories and plastic casing to overcome the difficulties in the above cleaning industry, thereby promoting better development of the cleaning industry.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A high-temperature carpet cleaning machine with quick disassembly and energy recovery comprises a detachable electric control box, a detachable clean water tank, and a detachable wastewater tank, which are arranged in sequence, as well as corresponding cleaning lines and wastewater recovery lines. The bottom of the detachable clean water tank is provided with a fixing groove, which is clamped and fixed with a corresponding limiting boss on the detachable electric control box, and the sides of the two are fixed by a lock.

[0006] The detachable sewage tank is located on the upper part of the detachable clean water tank and is fixed by correspondingly arranged limiting grooves and limiting bosses, and the sides of the two are fixed by locks;

[0007] An energy recovery device is also provided inside the detachable electrical control box, and the energy recovery device includes a fan and a hot water exchange pipe wrapped around the fan. The water inlet of the hot water exchange pipe is connected to the water outlet pipe of the cleaning route. The water outlet of the hot water exchange pipe leads to the heating device and is heated by the heating device. After being connected to the cleaning head, it is sprayed on the cleaning object through the water outlet outside the detachable electrical control box.

[0008] The front end surface of the detachable sewage tank is provided with a sewage suction port, and a sewage tank groove and a porous baffle are provided in the tank. The air and water sucked in by the sewage suction port enter the first air inlet through the hose and are filtered by the provided filter screen baffle before entering the filter bag;

[0009] The separated air enters the air intake duct through the second air inlet and leads to the fan and is discharged from the box through the fan;

[0010] The two sides of the porous baffle are fixed by sewage tank grooves located on the left and right sides of the detachable sewage tank, and the water buffered by the porous baffle flows into the water tank at the rear through the sewage water level flow channels provided on both sides.

[0011] The heat exchange water pipe is coiled and laid on the fan, and a heat insulation layer is cast on the outside of the pipe.

[0012] A fan protection device with a float is also provided behind the filter baffle inside the detachable sewage tank. The fan protection device is vertically arranged in the cavity behind the filter baffle, and its upper end is fixed on the air inlet slot of the sewage tank, and the air inlet slot of the sewage tank is fixed on the detachable sewage tank.

[0013] Butterfly locks are provided on both sides between the detachable sewage tank and the detachable clean water tank, and can be assembled, fixed and disassembled through the butterfly locks;

[0014] The back of the detachable clean water tank and the detachable electric control box are also provided with butterfly locks, which are used for assembly, fixation and disassembly.

[0015] The cleaning route connects the water outlet on the detachable clean water tank with the water inlet of the detachable electric control box, and the clean water in the detachable clean water tank is sucked into the water outlet pipe through the equipped water pump and leads to the water inlet of the hot water exchange pipe.

[0016] A flow sensor and a one-way valve for preventing reverse flow of high-temperature hot water are also provided between the water outlet of the energy recovery device and the heating device.

[0017] A transparent window is also provided on the top of the detachable sewage tank.

[0018] There are two energy recovery devices.

[0019] The beneficial effects of the utility model are:

[0020] (1) The utility model discloses a high-temperature carpet cleaning machine with quick disassembly and energy recovery. The purpose of quick disassembly and installation can be achieved through the mutual cooperation of the bosses and grooves between the detachable sewage tank, the detachable clean water tank, and the detachable electric control box, as well as the butterfly lock. The energy recovery device arranged in the detachable electric control box can recover the energy of the fan, which not only improves the life of the fan, but also achieves the goal of heating the water to a higher temperature when the heating element is low power or no heating element is used, thereby increasing the overall heating efficiency, recycling and reusing energy without waste, saving energy and high efficiency, and improving the overall life of the whole machine. At the same time, the porous baffle and fan protection device arranged on the detachable sewage tank can effectively prevent foam and water from entering the fan, thereby protecting the fan, improving the life of the fan, and saving costs.

[0021] (2) The energy recovery device includes a spirally arranged water pipe and an aluminum part cast outside the water pipe, which is put on the fan. Aluminum has good thermal conductivity and can transfer the heat generated by the fan operation to the internal hot water exchange pipe that is similar to a spring spiral. At the same time, the water in the hot water exchange pipe takes the heat away and sends it to the heating element, which can reduce the high temperature generated by the fan operation and solve the problem of high-power fans being connected in series, which causes the second fan to generate a huge workload due to the thrust generated by the first fan, thereby generating more high temperature, thereby increasing the life of the fan. At the same time, the water temperature has increased before entering the heating element through the energy recovery device on the outer ring of the fan. Even if the heating element is not used or the heating element only needs a small power to heat the water to a higher temperature, the working intensity of the heating element is reduced and the service life of the heating element is extended. The energy recovery device can make full use of energy without waste, save energy and protect the environment, and has higher efficiency. It can also quickly produce high-temperature and high-pressure hot water, thereby making the carpet clean more thoroughly.

[0022] (3) The coordination of the limiting bosses and fixing grooves between the detachable sewage tank, the detachable clean water tank and the detachable electric control box as well as the butterfly locks can achieve the purpose of quick disassembly and installation. The entire cleaning equipment can be quickly disassembled into three parts, which is easier to carry and can be quickly assembled, saving manpower, material resources and financial resources.

[0023] (4) In the energy recovery device, the heat exchange water pipe is wrapped around the outside of the fan in a spring-like manner, so the heat generated by the fan can be fully absorbed through the heat exchange water pipe. In addition, the aluminum cast around the heat exchange water pipe has good thermal conductivity and a stronger energy recovery function.

[0024] (5) The heat exchange pipes and flowing water in the energy recovery device, as well as the relatively thick aluminum alloy insulation layer installed on the outside, can isolate and reduce noise. BRIEF DESCRIPTION OF THE DRAWINGS

A heating element bracket is also provided above the thyristor, and the heating element 55 is installed above the heating element bracket.

[0061] When powered on, the clean water route and the sewage recycling route operate simultaneously.

[0062] Among them, the clear water route work is as follows:

[0063] After the water pump is turned on, external cold water enters the machine through the water inlet 25, and the flow adjustment knob 26 adjusts the amount of water entering the machine. After entering the machine, the cold water enters the water pump 44, and then enters the energy recovery device inlet 58-1 through the water pump outlet pipe 49. After passing through the energy recovery device 58-3, it comes out from the energy recovery device outlet 58-2 and enters the second energy recovery device 58-3, and then enters the heating element 55 through the energy recovery device main outlet 51, the water outlet hose 52, the flow sensor 53 and the one-way valve 54, and then sprays out high-temperature and high-pressure hot water through the heating element outlet hose 56 and the water outlet 57.

[0064] The sewage recycling route works as follows:

[0065] When the fan is powered on, the sucked sewage enters the sewage tank 29 through the sewage suction port 2. The air in the sewage enters the vacuum air intake chamber 29-5 and the second air intake 29-12 on the sewage tank air intake slot through the first air intake 29-4. The mixed water and air pass through the filter baffle 29-3 and enter the filter bag installed on the rear side of the filter baffle 29-3. The sucked hair is collected in the filter bag, and the water falls into the sewage tank 30 due to gravity. The water then flows into the sewage tank through the air intake ducts 29-13 on both sides of the sewage tank and the porous baffle 29-8 in the middle. In the first half, the separated air passes through the fan liquid level protection device 29-7, and enters the second air inlet 29-12 on the sewage tank air inlet groove body and the sewage tank air inlet pipe boss 29-6 in turn, and then enters the air inlet pipe 69, the clean water tank air inlet connecting pipe 71 and the suction cup 68 at the end thereof. The suction cup 68 enters the fan connecting pipe air inlet 50 through the suction square conversion cavity 65 and enters the fan 58, and then enters the second fan 58 through the fan outlet connecting hose 59 and the fan connecting pipe air inlet 60, and finally is discharged from the box through the fan rubber tube outlet 61.

[0066] It should be noted that the energy recovery device 58-3 in the clean water route of the present invention includes a fan and a hot water exchange pipe 58-6 wound around the fan, the interior of which is wound similar to a spring, and the hot water exchange pipe 58-6 is wrapped with aluminum. The whole is cast into a cylindrical shape and is sleeved on the outside of the fan 58. In order to improve energy recovery, two energy recovery devices 58-3 are provided inside the machine, and adjacent fans are arranged in series, and also include a fan air inlet 58-5, a fan air outlet 58-4 and a fan fixing bracket 58-7.

[0067] The working principle of the energy recovery device 58-3 is as follows:

[0068] External cold water enters the energy recovery device 58-3 through the water pump 44. The cold water entering the energy recovery device 58-3 takes away a large amount of heat generated by the fan 58 during operation through the heat exchange water pipe 58-6, and at the same time heats the temperature of the cold water, which not only reduces the workload of the heating element 55, but also ensures a higher water outlet temperature when the heating element 55 has very low power or there is no heating element, and at the same time greatly extends the life of the fan 58 and the heating element 55; firstly, it solves the problem that the electric heating cleaning equipment on the market cannot continuously provide high-temperature hot water when the water volume is large, and secondly, it solves the problem that the fan is not easy to dissipate heat and has a short life, and again solves the problem that water can be heated to a very high temperature without a heating element, so that energy is not wasted and the purpose of recycling is achieved.

[0069] In addition, in the energy recovery device, the hot water exchange pipe 58-6 is wrapped around the outside of the fan in multiple turns in a spring style, so the heat generated by the fan can be fully absorbed through the hot water exchange pipe. In addition, the aluminum cast around the hot water exchange pipe 58-6 has good thermal conductivity and a stronger energy recovery function.

[0070] In the sewage recovery device, a transparent window is installed on the top of the removable sewage tank 29, allowing for observation of the sewage inside and facilitating cleaning. A hose connects the sewage suction port 2 on the front of the removable sewage tank 29 to the first air inlet 29-4 inside the removable sewage tank 29. A float is installed inside the fan protection device 29-7 inside the removable sewage tank 29. When the sewage reaches a certain level, the float rises and blocks the air inlet 29-13, preventing sewage and foam from entering the fan 58. This significantly increases the lifespan of the fan 58 and resolves the current problem of shortened fan lifespans due to water ingress and foam.

[0071] The sewage tank air inlet pipe 69 inside the detachable sewage tank 29 is connected to the clean water tank suction connecting groove 38 and the clean water tank air inlet connecting pipe 71. The clean water tank air inlet connecting pipe 71 is connected to the square conversion cavity 45 through the suction cup 68 and the fan suction square conversion cavity interface 65. The square conversion cavity 45 is fixed above the circuit board support bracket 67 by screws and is located directly below the suction cup 68. It is connected to the fan 58 through a hose and the fan connecting pipe air inlet 66, thereby ensuring the integrity of the sewage recovery route.

[0072] A pressure sensor is provided on the water pump 44; a flow sensor 53 and a one-way valve 54 are provided between the water outlet 51 of the energy recovery device and the heating element 55. The one-way valve can prevent high temperature from flowing back into the flow sensor, thereby preventing high temperature from damaging the water flow sensor.

[0073] The utility model discloses a high-temperature carpet cleaning machine with quick disassembly and energy recovery, which can achieve the purpose of quick disassembly and installation through the mutual cooperation of the bosses and grooves between the detachable sewage tank, the detachable clean water tank, and the detachable electric control box and the butterfly lock; the energy of the fan can be recovered by the energy recovery device arranged in the detachable electric control box, which not only improves the service life of the fan, but also realizes that the water temperature can be heated to a higher temperature even when the heating element is low-power or no heating element is used, thereby increasing the overall heating efficiency, recycling and reusing energy without waste, saving energy and high efficiency, and improving the overall service life of the whole machine; at the same time, the porous baffle and the fan protection device arranged on the detachable sewage tank can effectively prevent foam and water splashes from entering the fan, thereby protecting the fan, improving the service life of the fan, and saving financial resources.
