Description

Technical field:

[0001] The utility model relates to a spray type dishwasher equipped with an elbow nozzle. Background technology:

[0002] The existing dishwasher's rotating strip nozzle only sprays a few jets of water. The low water pressure prevents clean dishes from being washed away, and grease stuck to the dishes cannot be rinsed away. High water pressure can knock over and damage clean dishes. Because the rotating strip nozzle only sprays a few jets of water, the resulting rotational thrust is too weak. Therefore, the rotating nozzle cannot be equipped with a rubber seal. This causes water leakage at the rotating nozzle, reducing the water pressure of the several jets. If a rubber seal is installed at the rotating nozzle, the increased friction prevents the rotating nozzle from rotating. Utility model content:

This type of dishwasher consists primarily of an outer shell, a stainless steel inner container, a sealed door, bowl baskets, a rotating strip nozzle, an L-shaped water pipe, a sink, an electric heating element, a stainless steel filter, a water tank, a water pump, an electric motor, an air compressor, a water inlet pipe, a water inlet solenoid valve, a motor-driven drain valve, a drain pipe, and a computer controller.

The central drum cover has several centrally symmetrical elbow nozzles on its cover plate, and several centrally symmetrical capillaries on its central drum. A rubber capillaries are installed between the lower ends of the elbow nozzles on the cover plate and the capillaries on the central drum. The upper elbow of the elbow nozzles is shaped like a threaded trumpet, and a sealing ring is installed at the lower end of the central drum on the central drum cover.The sealing ring is arranged on the center hole of the cabin of the strip-shaped rotary spray head, and a plurality of small holes are arranged on the upper section of the L-shaped water pipe between the central barrel cover plate of the strip-shaped rotary spray head and the cabin of the strip-shaped rotary spray head.

[0005] When using the spray dishwasher equipped with a curved plastic spraying nozzle, open the sealed door, take out the bowl basket, put the dirty dishes into the bowl basket, push the bowl basket with dirty dishes into the stainless steel inner container, put the dishwashing powder into the small pit on the inner surface of the sealed door, close the sealed door, the dishwashing powder in the small pit on the inner surface of the sealed door falls into the stainless steel inner container, plug in the power plug, and then select the dishwasher program through the button. Turn on the water valve of the tap, the computer control instrument supplies power to the water inlet solenoid valve to open, the tap water flows into the stainless steel inner container through the water inlet solenoid valve, and then flows from the stainless steel inner container to the sink, and then passes through the stainless steel filter screen into the water tank. When the set water level is reached, the computer control instrument stops supplying power to the water inlet solenoid valve, and the water inlet solenoid valve is closed. The dishwasher needs to use hot water to wash the dishes, the computer control instrument supplies power to the electric heating tube, heats the water in the sink and water tank, and when the water temperature in the sink and water tank reaches the set value, the computer control instrument stops supplying power to the electric heating tube. The computer control instrument starts the motor, the motor drives the rotating piston water pump and the rotating piston air compressor to rotate, the rotating piston of the rotating piston water pump rotates through the minimum radius of the involute cylinder, the rotating piston water pump previously pumps water from the water tank, and then pressurizes the water into the water outlet elbow tee. Because the motor drives the drain valve to be closed, the water pressurized into the water outlet elbow tee can only overcome the torsional spring to open the water outlet check valve and the pressure in the pressurized tank to enter the pressurized water tank. The rotating piston of the rotating piston air compressor rotates, and because the rotating piston of the rotating piston air compressor lags behind the rotating piston of the rotating piston water pump by a set angle, the rotating piston of the rotating piston water pump rotates through the minimum radius of the involute cylinder without contacting the maximum radius of the involute cylinder for a short time, the involute cylinder of the rotating piston water pump is not pressurized, the valve piece of the water outlet check valve is temporarily closed under the action of the torsional spring and the pressure in the pressurized water tank. The rotating piston of the rotating piston air compressor rotates through the minimum radius of the involute cylinder, and the compressed air previously discharged from the rotating piston air compressor overcomes the torsional spring to open the one-way air valve and the pressure in the pressurized water tank to enter the pressurized water tank. The rotating piston of the rotating piston air compressor rotates through the minimum radius of the involute cylinder without contacting the maximum radius of the involute cylinder for a short time, the involute cylinder of the rotating piston air compressor is not pressurized, the valve piece of the one-way air valve is temporarily closed under the action of the torsional spring and the pressure in the pressurized water tank. The upper half of the pressurized water tank is equipped with compressed air, and the lower half of the pressurized water tank is equipped with water. The compressed air in the upper half of the pressurized water tank enters the two gas and water mixing pipes from the two air inlet holes near the top of the pressurized water tank. The water in the lower half of the pressurized water tank enters the two gas and water mixing pipes from the two water inlet holes near the bottom of the pressurized water tank. The compressed air and water mixture from the two gas and water mixing pipes enters the two L-shaped water pipes, and then enters the central barrel of the central barrel cover plate of the strip-shaped rotating nozzle from the small holes on the upper segment of the L-shaped water pipe.A compressed air-water mixture emerges from several symmetrical tubes in the central barrel of the rotating strip nozzle's central barrel cover, passing through the nozzle's rubber tubing and into the elbow nozzle. From there, it sprays a mist of water onto the dishes in the basket, rinsing them. Simultaneously, the reaction force of the mist from the elbow nozzle's horn pushes the rotating strip nozzle in the opposite direction. The water used to rinse the dishes flows into the sink, where it passes through a filter and enters a water tank, where it is pumped away by a rotary piston pump for recycling. In the present invention, the process of spraying mist water from the elbow nozzle to rinse the tableware in the bowl basket is as follows: after the set time is reached, the computer controller energizes the motor to drive the drain valve to open, and the sewage in the water tank is pumped out by the rotary piston pump and pressed into the water outlet tee. Since the motor is pulling the drain valve in the open state, the water pressed into the drain tee can only overcome the torsion spring to open the valve plate of the drain check valve and be discharged from the drain pipe. Most of the water in the sink passes through the filter screen and flows into the water tank, where it is pumped out by the rotary piston water pump. The remaining water flows into the inclined pipe of the drain tee and is then sucked into the thin pipe of the drain tee, where it can overcome the torsion spring to open the valve plate of the drain check valve and be discharged from the drain pipe. At the same time, the sewage in the water tank is pumped out by the rotary piston pump and passes through the water outlet tee, generating negative pressure in the inclined pipe of the water outlet tee. The water in the pressurized water tank is pressed against the water outlet check valve under the pressure of the compressed air, causing the water outlet check valve to close. The rotary piston compressor continues to rotate. The piston passes the minimum radius of the involute cylinder and briefly breaks contact with the maximum radius. The involute cylinder loses air pressure, and the one-way air valve plate, acting on the torsion spring and the pressure in the pressurized water tank, briefly closes. Compressed air in the upper half of the pressurized water tank forces water in the lower half into two air-water mixing pipes. The compressed air-water mixture from the two mixing pipes enters two L-shaped water pipes, then through a circle of small holes in the upper section of the L-shaped pipes into the central barrel of the central barrel cover of the strip rotating nozzle. The compressed air-water mixture, exiting from several symmetrical tubes on the central barrel of the strip rotating nozzle cover, passes through the strip rotating nozzle's rubber tubing and enters the elbow nozzle. From the elbow nozzle's water horn, it is sprayed as a mist onto the tableware in the bowl basket, rinsing the dishes. The rinsed water flows into the sink. After the set time has elapsed and the water in the sink, water tank, and pressurized water tank has been drained, the computer controller stops powering the motor-driven drain valve, which closes. The computer controller also stops powering the motor, and the rotary piston water pump stops pumping water. The present invention's spray-type dishwasher equipped with an elbow nozzle begins its first rinse of the dishes in the dish basket: the computer controller energizes and opens the water inlet solenoid valve, allowing tap water to flow through the energized water inlet solenoid valve into the stainless steel inner container, then into the sink, through the stainless steel filter, and into the water tank. When the set water level is reached, the computer controller stops powering the water inlet solenoid valve, which closes.When the spray-type dishwasher equipped with an elbow nozzle of the present invention starts rinsing the dishes in the basket for the first time, it is not necessary to heat the water in the sink and water tank and no dishwashing powder is added. The other processes are the same as the initial wash. When the spray-type dishwasher equipped with an elbow nozzle of the present invention starts rinsing the dishes in the basket for the last time, it is not necessary to add dishwashing powder. The other processes are the same as the initial wash. After the spray-type dishwasher equipped with an elbow nozzle of the present invention starts rinsing the dishes in the basket for the last time, it is necessary to blow dry the dishes in the basket with hot air: the computer controller supplies power to the electric heating wire, the computer controller starts the motor, and the motor drives the rotary piston water pump and the rotary piston air compressor to rotate, because the pressurized water tank has been drained of water. The rotary piston water pump becomes a rotary piston air compressor. The rotary piston of the rotary piston water pump rotates past the minimum radius of the involute cylinder. Previously, the rotary piston water pump drew air from the water tank and then forced the compressed air into the water outlet tee. Because the motor-driven drain valve is closed, the compressed air entering the water outlet tee can only overcome the torsion spring that forces the water outlet check valve open and the pressure in the pressurized water tank to enter the pressurized water tank. The rotary piston of the rotary piston air compressor rotates. Because the rotary piston of the rotary piston air compressor lags behind the set angle of the rotary piston water pump's rotary piston, the rotary piston of the rotary piston water pump rotates past the minimum radius of the involute cylinder and briefly misses contact with the maximum radius of the involute cylinder. There is no air pressure in the involute cylinder, and the valve plate of the water outlet check valve is briefly closed by the torsion spring and the pressure in the pressurized water tank. The rotary piston compressor's rotary piston passes the minimum radius of the involute cylinder. The hot compressed air previously exiting the compressor overcomes the torsion spring, forces the check valve open, and forces the pressure within the pressurized water tank into the pressurized water tank. The rotary piston compressor's rotary piston passes the minimum radius of the involute cylinder and briefly avoids contact with the maximum radius. This depressurizes the involute cylinder, temporarily closing the check valve plate due to the torsion spring and the pressure within the pressurized water tank. Compressed air from the pressurized water tank enters the two air-water mixing pipes near the bottom of the pressurized water tank through two air inlets located near the top and two water inlets located near the bottom. The compressed air from the two air-water mixing pipes enters the two L-shaped water pipes, and then enters the central barrel of the central barrel cover of the linear rotary sprinkler through a circle of small holes in the upper section of the L-shaped pipes. A compressed air-water mixture emerges from several symmetrical tubes on the central barrel of the strip-shaped rotating nozzle's cover. The compressed air passes through the strip-shaped rotating nozzle's rubber tubes and enters the elbow nozzle. From there, it is blown through the elbow nozzle's water horn onto the dishes in the bowl basket, drying them. Simultaneously, the hot air from the elbow nozzle's horn creates a reaction force that pushes the strip-shaped rotating nozzle in the opposite direction.The hot and humid air in the stainless steel liner enters the S-shaped aluminum pipe of the condensation circulation composite pipe from the left upper side of the stainless steel liner. The indoor temperature air enters the plastic hose of the condensation circulation composite pipe from the lower end of the plastic hose. The indoor temperature air moves upward along the sparse spring of the condensation circulation composite pipe, absorbs the heat released by the hot and humid air in the S-shaped aluminum pipe of the condensation circulation composite pipe, and flows to the water tank. The heated air in the plastic hose of the condensation circulation composite pipe comes out from the upper end of the plastic hose, enters the inlet of the rotary piston air compressor along the air pipe, and forms a cycle. After the set time is reached, the computer control instrument stops supplying power to the electric heating wire, stops heating the compressed air from the rotary piston air compressor 11, and stops supplying power to the motor. The rotary piston water pump and the rotary piston air compressor stop rotating.

[0006] The spray-type dishwasher cannot use a centrifugal water pump because there are a large number of air bubbles in the water tank. When the centrifugal water pump is running, a large number of air bubbles enter the centrifugal water pump, which can cause cavitation and affect the water pumping of the centrifugal water pump. A large number of air bubbles in the water tank enter the rotary piston water pump when the rotary piston water pump is running, which does not cause cavitation and does not affect the water pumping of the rotary piston water pump. The rotary piston water pump is intermittent pumping. Before the rotary piston of the rotary piston water pump passes through the minimum radius of the involute cylinder, the water pressure is pressed into the water outlet elbow. Since the motor-drawn drain valve is in a closed state, the water pressed into the water outlet elbow can only overcome the torsion spring to open the water outlet check valve and the pressure in the pressurized water tank to enter the pressurized water tank. The rotary piston of the rotary piston air compressor rotates. Since the rotary piston of the rotary piston air compressor lags behind the rotary piston of the rotary piston water pump by a set angle, the rotary piston of the rotary piston water pump passes through the minimum radius of the involute cylinder for a short time without contacting the maximum radius of the involute cylinder. The water pressure in the involute cylinder of the rotary piston water pump is not high, and the valve plate of the water outlet check valve is temporarily closed under the action of the torsion spring and the pressure in the pressurized water tank. The rotary piston of the rotary piston air compressor passes through the minimum radius of the involute cylinder. The compressed air from the rotary piston air compressor before the rotary piston air compressor enters the pressurized water tank by overcoming the torsion spring to open the one-way air valve and the pressure in the pressurized water tank. The reciprocating piston air compressor has a dead point, an intake stroke and a compression stroke, so the reciprocating piston air compressor has low efficiency and high noise.

[0014] Figure 4 and Figure 5 As shown, the structure of the rotary piston air compressor 11 is as follows: It consists of an involute cylinder 1100, a central rotating body 1101 with a through-groove, a left fixed baffle 1103, a left hollow shaft 1105, a left end cap 1107, a left bearing, left and right fixed baffles 1104, a right hollow shaft 1106, a right end cap 1108, a right bearing, a dome-shaped cross-gate piston 1102, a spring plate, a return spring, an inlet slit, and an outlet slit.

[0015] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, when using a spray-type dishwasher equipped with an elbow spray nozzle 203, the user opens the sealed door, removes the bowl basket 1, places the dirty bowls in the basket 1, and pushes the dirty bowl basket 1 into the stainless steel inner tank 0. Dishwashing powder is placed in the small recess on the inner surface of the sealed door. The sealed door is closed, and the dishwashing powder in the small recess on the inner surface of the sealed door falls into the stainless steel inner tank 0. The power plug is plugged in, and the dishwasher program is selected using the buttons. The tap water valve is turned on, and the computer controller energizes and opens the water inlet solenoid valve 12. Tap water flows through the energized water inlet solenoid valve 12 into the stainless steel inner tank 0, then flows from the stainless steel inner tank 0 to the sink 5, and then passes through the stainless steel filter 7 into the water tank 6. When the set water level is reached, the computer controller stops energizing the water inlet solenoid valve 12, and the water inlet solenoid valve 12 is powered off. The dishwasher requires hot water for the initial wash of dishes. The computer controller supplies power to the electric heating tube to heat the water in the sink 5 and the water tank 6. When the water temperature in the sink 5 and the water tank 6 reaches the set value, the computer controller stops supplying power to the electric heating tube. The computer controller starts the motor 10, which drives the rotary piston water pump 9 and the rotary piston air compressor 11 to rotate. The rotary piston of the rotary piston water pump 9 rotates past the minimum radius of the involute cylinder. Previously, the rotary piston water pump 9 pumped water from the water tank 6 and then pressed the water into the water outlet tee. Since the motor-driven drain valve 15 is in a closed state, the water pressed into the water outlet tee can only overcome the torsion spring to flush open the water outlet check valve 13 and the pressure in the pressurized water tank 8 to enter the pressurized water tank 8. The rotary piston of the rotary piston air compressor 11 rotates. Because the rotary piston of the rotary piston air compressor 11 lags behind the set angle of the rotary piston of the rotary piston water pump 9, the rotary piston of the rotary piston water pump 9 rotates past the minimum radius of the involute cylinder and briefly does not contact the maximum radius of the involute cylinder. As a result, there is no water pressure in the involute cylinder of the rotary piston water pump 9, and the valve plate of the water outlet check valve 13 is briefly closed due to the action of the torsion spring and the pressure in the pressurized water tank 8. When the rotary piston of the rotary piston air compressor 11 rotates past the minimum radius of the involute cylinder, the compressed air previously discharged from the rotary piston air compressor 11 overcomes the torsion spring, opens the check valve 14, and the pressure in the pressurized water tank 8, and enters the pressurized water tank 8. The rotary piston of the rotary piston air compressor 11 rotates past the minimum radius of the involute cylinder and briefly does not contact the maximum radius of the involute cylinder. There is no air pressure in the involute cylinder of the rotary piston air compressor 11, and the valve plate of the one-way air valve 14 is briefly closed under the action of the torsion spring and the pressure in the pressurized water tank 8. The upper half of the pressurized water tank 8 is filled with compressed air, and the lower half of the pressurized water tank 8 is filled with water. The compressed air in the upper half of the pressurized water tank 8 enters the two air-water mixing pipes 4 from the two air inlet holes on the two air-water mixing pipes 4 near the bottom of the pressurized water tank 8. The water in the lower half of the pressurized water tank 8 enters the two air-water mixing pipes 4 from the two water inlets of the two air-water mixing pipes 4 near the bottom of the pressurized water tank 8.The compressed air and water mixture from the two air and water mixing pipes 4 enters the two L-shaped water pipes 3, and then enters the central barrel of the central barrel cover plate 201 of the strip-shaped rotary spray head 2 from the small holes on the upper section of the L-shaped water pipes 3. The compressed air and water mixture from the several center-symmetrical thin pipes on the central barrel cover plate 201 of the strip-shaped rotary spray head 2 enters the elbow-shaped nozzle 203 through the rubber thin pipes 204 of the strip-shaped rotary spray head 2, and then is sprayed in the form of mist water from the water horn pipe of the elbow-shaped plastic nozzle 203 to the dishes in the bowl basket 1 to wash the dishes. At the same time, the mist water sprayed from the horn pipe of the elbow-shaped plastic nozzle 203 generates a reaction force to push the strip-shaped rotary spray head 2 to rotate in the opposite direction. The water used to wash the dishes in the bowl basket 1 flows into the sink 5, and the water in the sink 5 passes through the filter screen 7 into the water tank 6 and is pumped away by the rotary piston water pump 9 for recycling. In the process of washing the dishes in the bowl basket 1 by the mist water sprayed from the elbow-shaped nozzle 203 in the utility model, after reaching the set time, the computer control instrument supplies power to the motor-drawn drain valve 15 to open, the sewage in the water tank 6 is pumped out by the rotary piston pump 9, and is pressed into the water outlet elbow tee. Since the motor-drawn drain valve 15 is in the open state, the water pressed into the drain elbow tee can only overcome the torsional spring to open the valve disc of the drain one-way valve 16 and is discharged from the drain pipe. Most of the water in the sink 5 flows into the water tank 6 through the filter screen 7 and is pumped away by the rotary piston water pump 9, and the other part of the water flows into the inclined pipe of the drain elbow tee, and then is sucked into the thin pipe of the drain elbow tee to overcome the torsional spring to open the valve disc of the drain one-way valve 16 and is discharged from the drain pipe. At the same time, after the sewage in the water tank 6 is pumped out by the rotary piston pump 9, it passes through the water outlet elbow tee, and a negative pressure is generated in the water outlet elbow tee. The water in the pressurized water tank 8 is pressed to the water outlet one-way valve under the pressure of the compressed air, so that the water outlet one-way valve is closed. The rotary piston air compressor 11 continues to rotate, the rotary piston of the rotary piston air compressor 11 rotates through the minimum radius of the involute cylinder, and is not in contact with the maximum radius of the involute cylinder 1100 for a short time. There is no air pressure in the involute cylinder 1100 of the rotary piston air compressor 11, the valve disc of the one-way air valve 14 is temporarily closed under the action of the torsional spring and the pressure in the pressurized water tank 8. The compressed air in the upper half of the pressurized water tank 8 presses the water in the lower half of the pressurized water tank 8 into the two air and water mixing pipes 4. The compressed air and water mixture from the two air and water mixing pipes 4 enters the two L-shaped water pipes 3, and then enters the central barrel of the central barrel cover plate 201 of the strip-shaped rotary spray head 2 from the small holes on the upper section of the L-shaped water pipes 3. The compressed air and water mixture from the several center-symmetrical thin pipes on the central barrel cover plate 201 of the strip-shaped rotary spray head 2 enters the elbow-shaped nozzle 203 through the rubber thin pipes 204 of the strip-shaped rotary spray head 2, and then is sprayed in the form of mist water from the water horn pipe of the elbow-shaped nozzle 203 to the dishes in the bowl basket 1 to wash the dishes. The water used to wash the dishes in the bowl basket 1 flows into the sink 5.After the set time has elapsed and the water in sink 5, water tank 6, and pressurized water tank 8 has been drained, the computer controller de-energizes motor-driven drain valve 15, closing it. The computer controller also de-energizes motor 10, and rotary piston water pump 9 stops pumping water. The spray-type dishwasher equipped with elbow nozzle 203 of the present invention begins the first rinse of the dishes in dish basket 1: the computer controller energizes and opens water inlet solenoid valve 12. Tap water flows through the opened water inlet solenoid valve 12 into stainless steel inner liner 0, then from stainless steel inner liner 0 to sink 5, then through stainless steel filter 7 and into water tank 6. When the set water level is reached, the computer controller de-energizes water inlet solenoid valve 12, closing it. During the first rinse of the dishes in dish basket 1 of the spray-type dishwasher equipped with elbow nozzle 203 of the present invention, there is no need to heat the water in sink 5 and water tank 6, nor is there any need to add dishwashing powder. The rest of the process is the same as the initial rinse. During the final rinse of the dishes in basket 1, a spray-type dishwasher equipped with an elbow nozzle 203 according to the present invention does not require dishwashing powder. The rest of the process is the same as the initial rinse. After the final rinse of the dishes in basket 1, the dishes in basket 1 need to be dried with hot air: the computer controller supplies power to the heating wire, which activates motor 10. Motor 10 drives rotary piston water pump 9 and rotary piston air compressor 11. Since pressurized water tank 8 has been drained, rotary piston water pump 9 becomes rotary piston air compressor 11. The rotary piston of rotary piston water pump 9 rotates past the minimum radius of the involute cylinder. Previously, rotary piston water pump 9 drew air from water tank 6 and then pressed compressed air into the water outlet tee. Because the drain solenoid valve is closed, the compressed air entering the water outlet tee can only overcome the torsion spring that forces open the water outlet check valve 13 and the pressure within pressurized water tank 8 to enter pressurized water tank 8. The rotary piston of rotary piston air compressor 11 rotates. Because the rotary piston of rotary piston air compressor 11 lags behind the set angle of the rotary piston of rotary piston water pump 9, the rotary piston of rotary piston water pump 9 rotates past the minimum radius of the involute cylinder and briefly does not contact the maximum radius of the involute cylinder. As a result, there is no air pressure in the involute cylinder of rotary piston water pump 9, and the valve plate of water outlet check valve 13 is briefly closed due to the action of the torsion spring and the pressure in pressurized water tank 8. When the rotary piston of rotary piston air compressor 11 rotates past the minimum radius of the involute cylinder, the hot compressed air previously discharged from rotary piston air compressor 11 overcomes the torsion spring, opens the check valve 14, and the pressure in pressurized water tank 8, and enters pressurized water tank 8. The rotary piston of the rotary piston air compressor 11 rotates past the minimum radius of the involute cylinder and does not contact the maximum radius of the involute cylinder 1100 for a short time. There is no air pressure in the involute cylinder 1100 of the rotary piston air compressor 11, and the valve plate of the one-way air valve 14 is briefly closed under the action of the torsion spring and the pressure in the pressurized water tank 8.Compressed air from the pressurized water tank 8 enters the two air-water mixing tubes 4 through two air inlet holes located near the top and bottom of the two air-water mixing tubes 4, and two water inlets located near the bottom. The compressed air exits the two air-water mixing tubes 4 and enters the two L-shaped water tubes 3. Then, through a circle of small holes in the upper section of the L-shaped water tubes 3, it enters the central barrel of the central barrel cover 201 of the strip-shaped rotating spray head 2. The compressed air-water mixture, exiting from several symmetrical thin tubes on the central barrel cover 201 of the strip-shaped rotating spray head 2, passes through the rubber thin tubes 204 of the strip-shaped rotating spray head 2 and enters the elbow nozzle 203. From the water horn of the elbow nozzle 203, it is blown onto the tableware in the bowl basket 1, drying the dishes. Simultaneously, the hot air from the horn of the elbow nozzle 203 generates a reaction force that drives the strip-shaped rotating spray head 2 in the opposite direction. The hot and humid air inside the stainless steel inner tube 0 enters the S-shaped aluminum tube of the condensation circulation composite pipe from its upper left side. Room temperature air then enters the plastic hose of the condensation circulation composite pipe from its lower end. The room temperature air moves upward along the sludge spring of the condensation circulation composite pipe, absorbing the heat released by the hot and humid air inside the S-shaped aluminum tube. The heat released by the hot and humid air inside the S-shaped aluminum tube condenses into liquid water and flows into the water tank 5. The heated air inside the plastic hose exits from its upper end, travels along the air pipe, and enters the inlet of the rotary piston air compressor 11, completing the circulation. After the set time is reached, the computer controller stops powering the electric heating wire, stopping the heating of the compressed air from the rotary piston air compressor 11. The computer controller also stops powering the motor 10, causing the rotary piston water pump 9 and the rotary piston air compressor 11 to stop rotating.
