Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a clothes dryer. Background Technology

[0002] A clothes dryer is a device that quickly dries wet clothes. It consists of a cabinet and a door. The cabinet has a loading port, and the door is used to open and close it. While the dryer is operating, the door must remain closed to prevent hot air from escaping, thus ensuring effective drying. After the dryer has finished drying, the user needs to open the door to remove the clothes. Because the drying process ensures optimal drying, the door is usually quite secure and requires considerable pulling force to open.

[0003] Currently, dryer door switches typically use either mechanical or electronic switches. When the door switch is mechanical, the user needs to apply a certain amount of force to pull the switch. When the door switch is electronic, it includes a sensor and control circuitry. When the user approaches the dryer, the sensor detects the user's presence and automatically opens the door via mechanical transmission.

[0004] However, when the door switch is mechanical, it requires a certain amount of arm strength from the user. For people with poor arm strength, opening the door can be difficult. Furthermore, since the amount of pulling force needs to be estimated by the user, too little or too much force can cause discomfort, resulting in a poor experience for users who seek a smooth experience.

[0005] When a dryer needs to be moved from one location to another, the traditional solution is to use another trolley to move the machine, which is time-consuming and labor-intensive. Usually, a second person is needed to assist in moving the dryer and keeping it from falling off. There is also the problem of damage to the machine during the moving process.

[0006] Therefore, this application proposes a clothes dryer. Summary of the Invention

[0095] Specifically, the cabinet includes a placement space inside the cabinet, wherein the drying cylinder is located within the placement space.

[0096] The drying cylinder includes a drying port (not shown) located at the side end of the drying cylinder, wherein the drying port is located on the side of the drying cylinder near the inlet, and the drying port is arranged opposite to the inlet.

[0097] The drying drum 12 has a clothing receiving cavity, which is connected to the drying outlet. Clothes can be placed in the clothing receiving cavity through the loading port and the drying outlet. The clothing receiving cavity is used to hold the clothes to be dried so that they can be dried in the clothing receiving cavity.

The door 5 is located on one side of the drying drum 12, and clothes are put in or taken out by opening and closing the door 5, thus realizing the loading and unloading of clothes in the clothes receiving cavity.

[0099] In some embodiments, the dryer also includes a cylinder 52, which is disposed at the bottom of the housing and can be pushed to extend or retract by applying driving air to the cylinder 52.

[0100] In some embodiments, the dryer also includes rollers 54, which are disposed at the bottom of the cylinder 52. Driving air is applied to the cylinder 52 to push the cylinder 52 out of the housing. The rollers 54 are in contact with the ground. The rollers 54 and the cylinder 52 can support the entire dryer, thereby facilitating the movement of the entire machine. The rollers 54 can roll relative to the ground to reduce the resistance of moving the dryer and facilitate the repositioning of the dryer.

[0101] In some embodiments, the dryer further includes an auxiliary movement module 4 disposed inside the housing, which is used to apply air thrust to the cylinder 52 to drive the cylinder 52 to move.

[0102] refer to Figure 1 The auxiliary movement module 4 includes a power source 41, which is used to provide compressed air.

[0103] refer to Figure 1 The auxiliary moving module 4 also includes a pressure reducing device 42, which is used to reduce the pressure of the air flowing through it. The air inlet of the pressure reducing device 42 is connected to the air outlet of the power source, so that the pressure reducing device 42 can reduce the pressure of the air flowing out of the power source and output the reduced air.

[0104] The auxiliary moving module 4 also includes a pressure regulating device 43, which is used to regulate the air pressure. The air inlet of the pressure regulating device 43 is connected to the air outlet of the pressure reducing device 42, and the pressure regulating device 43 outputs pilot pressure.

[0105] refer to Figure 1 The pressure is adjusted to the maximum pressure of the pressure regulating device 43 by the pressure reducing device 42.

[0106] refer to Figure 1 The auxiliary moving module 4 also includes a first channel 479, which is used to transmit air.

[0107] refer to Figure 1The auxiliary moving module 4 also includes a relay valve 45, wherein the air inlet of the relay valve 45 is connected to the air outlet of the power source, and the air outlet of the relay valve 45 is connected to the inlet of the first channel 479; the pilot port of the relay valve 45 is connected to the pressure regulating device 43, the relay valve 45 receives the pilot pressure output by the pressure regulating device 43, and the relay valve 45 amplifies the flow according to the pilot pressure and outputs driving air to the first channel 479.

[0108] When the cylinder 52 cover retracts into the housing, the outlet of the first channel 479 is connected to the cylinder 52. By driving air, force is applied to the cylinder 52 to push it to move. The movement of the cylinder 52 can drive the roller 54 to contact the ground. The roller 54 and the cylinder 52 can support the entire dryer, thus facilitating the movement of the dryer.

[0109] The dryer includes an auxiliary moving module 4, which includes a power source, a pressure reducing device 42, a pressure regulating device 43, a relay valve 45, and a first channel 479. It can generate air with a certain pressure to apply force to the cylinder 52. By driving the air to apply force to the cylinder 52, the cylinder 52 is pushed to move. The movement of the cylinder 52 can drive the roller 54 to contact the ground. The roller 54 and the cylinder 52 can support the entire dryer, thus facilitating the movement of the dryer. The machine can be moved by the cylinder 52 and the roller 54 at the bottom, which is convenient, fast, time-saving, labor-saving, and can avoid damage to the machine during the transportation process.

[0110] In some embodiments, four cylinders 52 may be provided, all four cylinders 52 are connected to the first channel 479, and the four cylinders 52 are respectively located at the bottom of the housing. When the four cylinders 52 are subjected to pressure applied by the drive, the four cylinders 52 can extend out of the bottom of the housing at the same time, and the rollers 54 contact the ground to support the dryer.

[0111] In some embodiments of this application, the power source may be a pump body, wherein the power source may be a small pump.

[0112] In some embodiments of this application, the pressure reducing device 42 is a pressure reducing valve.

[0113] In some embodiments, the auxiliary mobility module 4 may include a first barometric pressure sensor 471.

[0114] The first air pressure sensor 471 is used to detect the air pressure between the pilot port of the relay valve 45 and the pressure regulating device 43, and the pressure value detected by the first air pressure sensor 471 is recorded as the pilot pressure.

[0115] In some embodiments, the dryer also includes a door lock connected to the housing, which locks the door to prevent the door from opening the dispensing opening or unlocks the door to allow the door to open the dispensing opening.

[0116] Currently, opening the door of a dryer requires a certain amount of arm strength from the user, which can be difficult for people with limited arm strength. Furthermore, because the amount of pulling force needs to be estimated by the user, too little or too much force can cause discomfort, resulting in a poor experience for users who prefer a smooth operation. Alternatively, the dryer may frequently misinterpret the user's intention to open the door, causing it to open unnecessarily.

[0117] In some embodiments, the dryer may include a second channel 44, the outlet of which is connected to a door.

[0118] In some embodiments, the auxiliary movement module 4 may include a sixth solenoid valve 480, which is used to control the connection between the first channel 479 or the second channel 44.

[0119] The relay valve 45 receives the pilot pressure output by the pressure regulating device 43, and the relay valve 45 outputs driving air to the first channel 479 or the second channel 44 according to the pilot pressure.

[0120] When the sixth solenoid valve 480 is connected to the first channel 479, it applies force to the cylinder 52 by driving air to make the cylinder 52 move.

[0121] When the sixth solenoid valve 480 is connected to the second channel 44, it applies force to the door body by driving air to unlock the door body and the door lock.

[0122] This application allows for the extension of the auxiliary movement module 4 with a second channel 44 and a door lock, enabling machine handling via the bottom cylinder 52 and rollers 54. This is convenient, fast, time-saving, and labor-saving, and avoids machine damage during handling. Furthermore, when the sixth solenoid valve 480 is connected to the second channel 44, a person with weak arm strength can use the relay valve 45 to output drive air to the second channel 44 based on the pilot pressure. This drive air applies force to the door to unlock it from the door lock, thus assisting the user in opening the door.

[0123] In some embodiments, the flow path between the pilot port of the relay valve 45 and the pressure regulating device 43 is a pilot flow path. The first air pressure sensor 471 is used to detect the air pressure value in the pilot flow path.

[0124] In some embodiments, the auxiliary movement module 4 may include a second pressure sensor 478, which is used to detect the air pressure in the first channel 479 and record the detected air pressure as a second output pressure.

[0125] In some embodiments, the dryer further includes a controller configured to control a second output pressure to tend to equal the pilot pressure.

[0126] In some embodiments, the pressure regulating device 43 may include a second solenoid valve 431, the inlet of which is connected to the air outlet of the pressure reducing device 42.

[0127] In some embodiments, the pressure regulating device 43 may include a second solenoid valve 432, the inlet of which is connected to the outlet of the second solenoid valve 431 and the pilot port of the relay valve 45.

[0128] The inlet of the first solenoid valve 431 is connected to the outlet of the pressure reducing valve.

[0129] The inlet of the second solenoid valve 432 is connected to the outlet of the second solenoid valve 431 and the pilot port of the auxiliary door opening relay valve 45.

[0130] When the pressure regulating device 43 increases the pressure, the second solenoid valve 431 and the second solenoid valve 432 are energized;

[0131] When the pressure regulating device 43 is maintaining pressure, the second solenoid valve 431 is de-energized and the second solenoid valve 432 is energized.

[0132] When the pressure regulating device 43 reduces the pressure, the second solenoid valve 431 and the second solenoid valve 432 are de-energized.

[0133] The attached diagram shows the second solenoid valve 431 and the second solenoid valve 432 in a de-energized state.

[0134] The connection and disconnection of the second solenoid valve 431 are controlled by energizing and de-energizing the second solenoid valve 431, and the disconnection and connection of the second solenoid valve 432 are controlled by energizing and de-energizing the second solenoid valve 432.

[0135] Specifically, when the second solenoid valve 431 is energized, the second solenoid valve 431 is connected; when the second solenoid valve 431 is de-energized, the second solenoid valve 431 is disconnected. When the second solenoid valve 432 is de-energized, the second solenoid valve 432 is connected; when the second solenoid valve 432 is energized, the second solenoid valve 432 is disconnected.

[0136] The outlet of the second solenoid valve 432 is connected to other devices or is open.

[0138] In some embodiments, the pressure regulating device 43 further includes a flow regulator 433, wherein the inlet of the flow regulator 433 is connected to the pressure reducing device 42, and the flow regulator 433 is used to control the flow rate in the flow path between the auxiliary pressure regulating device 43 and the pilot port of the relay valve 45. Since the relay valve 45 has the function of amplifying the flow rate, the regulation of the flow path between the pressure regulating device 43 and the pilot port of the relay valve 45 is for the purpose of regulating the output flow rate of the relay valve 45.

[0139] Among them, the flow regulator 433 can be a throttle valve.

[0140] In some embodiments of this application, the auxiliary movement module 4 further includes an air pressure control device 473. The inlet of the air pressure control device 473 is connected to the air outlet of the power source. The air pressure control device 473 is used to control the air pressure in the flow path between the air outlet of the power source and the pressure reducing device 42 to be lower than the overflow air pressure. When the air pressure in the flow path between the air outlet of the power source and the pressure reducing device 42 is not lower than the overflow air pressure, the air pressure control device 473 is turned on to reduce the flow path air pressure.

[0141] The air pressure control device 473 is an overflow valve, wherein the inlet of the overflow valve is connected to the air outlet of the power source, and the outlet of the overflow valve is connected to other devices or is open.

[0142] In some embodiments of this application, the auxiliary movement module 4 further includes a one-way airflow device 474, which is used to prevent air backflow. The inlet of the one-way airflow device 474 is connected to the air outlet of the power source, and the outlet of the one-way airflow device 474 is connected to the pressure reducing device 42.

[0143] Among them, the one-way air device 474 is a one-way valve.

[0144] In some embodiments of this application, the auxiliary movement module 4 further includes an emergency ventilation device 475, which is used to cut off the air flow path between the power source and the pressure reducing device 42 and the relay valve 45.

[0145] In the event of a malfunction in the air circuit that causes continuous air to push the cylinder 52 or the door, the air circuit can be cut off using the emergency exhaust device 475, while simultaneously venting the air from the side of the emergency exhaust device 475 away from the power source.

[0146] Among them, the emergency ventilation device 475 can be a shut-off valve.

[0147] In some embodiments of this application, the auxiliary moving module 4 further includes a filter device 477, which is connected to the air inlet of the pressure regulating device 43 and the air inlet of the relay valve 45 on the side near the power source. The filter device 477 is used to filter impurities in the air to ensure the purity of the gas.

[0148] Among them, the filtration device 477 can be a filter.

[0149] In some embodiments of this application, the auxiliary mobile module 4 also includes a backup air source device 476. When the power source fails, the backup air source device 476 can replace the power source pump for a period of time, improving the device's durability and making up for the gap before after-sales service.

[0150] The backup gas source device 476 can be a gas storage tank of a certain volume.

[0151] The air outlet of the power source is connected to the air inlet of the air pressure control device 473 and the air inlet of the one-way air device 474. The air outlet of the one-way air device 474 is connected to the air inlet of the air storage device. The air outlet of the air storage device is connected to the air inlet of the emergency exhaust device 475. The air outlet of the emergency exhaust device 475 is connected to the air inlet of the filter device 477. The air outlet of the filter device 477 is connected to the air inlet of the pressure reducing device 42 and the air inlet of the relay valve 45.

[0152] The power source compresses air into the main air circuit, and the air pressure in the main air circuit is set by the air pressure control device 473. After passing through the filter device 477, the air in the main air circuit is divided into two paths, flowing into the pressure reducing device 42 and the relay valve 45 respectively. The set pressure P2 of the pressure reducing device 42 is used as the air duct pressure of the pressure regulating device 43. The pressure regulating device 43 outputs a pilot pressure to the pilot port of the relay valve 45, controlling the second output pressure to tend to be equal to the pilot pressure.

[0153] In some embodiments of this application, when the pressure regulating device 43 enters the pressurization state, and the pressure value detected by the first pressure sensor 471 differs significantly from the air pressure detected in real time by the second pressure sensor 478, it indicates that the relay valve 45 is damaged and needs to be replaced or repaired in time.

[0154] In some embodiments of this application, when it is necessary to activate the movement mode to control the extension cylinder 52 and the roller 54, the auxiliary movement module 4 is set to F3 as the target pressure value, and the corresponding pilot pressure is P3.

[0155] When the mobile mode is activated, the controller receives a first signal to control the sixth solenoid valve 480 to connect to the first channel 479, the pressure regulating device 43 enters the pressurization state, the first air pressure sensor 471 detects the pilot pressure in real time, the second pressure sensor 478 detects the second output pressure in real time, and adjusts the second output pressure to be equal to the pilot pressure.

[0156] When the second output pressure is detected to be less than the pilot pressure P3, the sixth solenoid valve 480 is controlled to connect to the first channel 479, and the second solenoid valve 431 and the second solenoid valve 432 are energized to increase the second output pressure, so that the second output pressure tends to be equal to the pilot pressure P3.

[0157] When the difference between the second output pressure and the pilot pressure P3 is less than the first preset difference, the second output pressure is not equal to the pilot pressure P3. The sixth solenoid valve 480 is connected to the first channel 479, the second solenoid valve 431 is energized, and the second solenoid valve 432 is de-energized to stop the pressurization and enter the pressure holding state to keep the second output pressure unchanged.

[0158] When the second output pressure is detected to be greater than the pilot pressure P3, the sixth solenoid valve 480 is controlled to connect to the first channel 479, and the second solenoid valves 431 and 432 are de-energized, entering the pressure reduction state and reducing the second output pressure.

[0159] When the second output pressure equals the pilot pressure P3, the sixth solenoid valve 480, the second solenoid valve 431 and the second solenoid valve 432 are de-energized. The sixth solenoid valve 480 disconnects from the first channel 479. At this time, the second output pressure remains unchanged and the pressure inside the cylinder 52 remains constant. No external power is needed at this time. The power can be cut off and the dryer can be moved to the target position. At this time, the roller 54 extends out of the housing. The dryer can be moved to the target position with the help of the roller 54, making it more convenient to move the dryer.

[0160] When the dryer is moved to the target position, the dryer is powered on. After the controller is powered on, if the controller detects that it was in moving mode before the power failure and that the sixth solenoid valve 480 was de-energized, it will still control the sixth solenoid valve 480, the second solenoid valve 431 and the second solenoid valve 432 to remain de-energized so that the second output pressure remains unchanged, so that the cylinder 52 maintains its original pressure state and prevents the cylinder 52 from retracting back into the housing.

[0161] When the mobile mode is turned off, the controller receives a second signal to control the sixth solenoid valve 480 to connect to the first channel 479, adjust the second output pressure to reduce, the cylinder 52 retracts back into the housing, and the dryer supported by the cylinder 52 will slowly descend to the ground. After descending to the ground, the sixth solenoid valve 480, the second solenoid valve 431 and the second solenoid valve 432 are all de-energized.

[0162] The power source compresses air into the main air circuit, where the air pressure is set by the overflow valve. After passing through the air tank, the air from the main air circuit splits into two streams, flowing into the pressure reducing valve and the relay valve 45 respectively. The pressure reducing valve's set pressure P2 serves as the duct pressure for the pressure regulating device 43. The pilot pressure is output to the pilot port of the relay valve 45 via the opening and closing of the second solenoid valve 431 and the second solenoid valve 432. The relay valve 45 outputs to a three-position three-way solenoid valve. When the A side of the sixth solenoid valve 480 is energized, it switches to the moving mode, connecting the sixth solenoid valve 480 to the first channel 479. The second output pressure of the four cylinders 52 is kept consistent with the pilot pressure.

[0163] When the B side of the sixth solenoid valve 480 is energized, it switches to the air-assisted door opening mode, and the sixth solenoid valve 480 is connected to the second channel 44. Afterwards, the pressure output at the control door end is kept consistent with the pilot pressure.

[0164] When neither side AB is powered, the second output pressure remains constant. If the door is open, the pressure in the second channel 44 is the same as the air pressure; if the door is closed and a sealed space is formed, the pressure in the second channel 44 remains constant.

[0165] In some embodiments, the dryer also includes a spring 53, which is disposed at the bottom of the housing and corresponds to the cylinder 52. The spring 53 can improve the ability to support the dryer, so that when the cylinder 52 retracts, it can slowly retract into the housing under the action of the spring 53.

[0166] In some embodiments, the dryer may include a second pressure sensor 472 for detecting the air pressure value in the second channel 44.

[0167] In some embodiments of this application, the second channel 44 may be a single channel, with the inlet of the second channel 44 connected to the outlet of the sixth solenoid valve 480, and the outlet of the second channel 44 being opposite to the door when the door closes the dispensing port.

[0168] In some embodiments of this application, the second channel 44 may include a main second channel 441, the inlet of which is connected to the outlet of the sixth solenoid valve 480.

[0169] The second channel 44 also includes at least two auxiliary second channels 442, one end of each of the two auxiliary second channels 442 being connected to the exit of the main second channel 441, and the exits of the two auxiliary second channels 442 corresponding to different positions of the door.

[0170] In some embodiments of this application, the door body may include a door handle 51, wherein a pressure sensor 46 is disposed on one side of the door handle, and when the door body closes the delivery port, the outlet of the second channel 44 is located on one side of the door handle at a position corresponding to the door body.

[0171] See Figure 4 In some embodiments of this application, the number of pressure sensors 46 is the same as the number of auxiliary second channels 442. The pressure sensors 46 and auxiliary second channels 442 are in one-to-one correspondence. That is, the pressure sensors 46 are located on one side of the outlet of the auxiliary second channel 442. Furthermore, the distance between each pressure sensor 46 and its corresponding outlet of the auxiliary second channel 442 is equal or the difference between two adjacent distances is within a certain range, thereby ensuring the stability of the values ​​detected by the pressure sensors 46.

[0172] The interaction force is the average value of the values ​​detected by the pressure sensor 46.

[0173] In some embodiments of this application, the housing includes a dispensing port located on the front side of the housing, and a door is connected to the housing and used to open or close the dispensing port. A door lock connects the housing, locking the door to prevent the door from opening the dispensing port, or unlocking the door to allow the door to open the dispensing port. An auxiliary movement module 4 is located inside the housing and is used to apply air thrust to the door to unlock the door from the door lock.

[0174] The auxiliary moving module 4 includes a power source, a pressure reducing device 42, a pressure regulating device 43, a second channel 44, a relay valve 45, a pressure sensor 46, a first air pressure sensor 471, and a second pressure sensor 478. The power source provides compressed air. The pressure reducing device 42 reduces the pressure of the air flowing through it, and its air inlet is connected to the air outlet of the power source. The pressure regulating device 43 regulates the air pressure, and its air inlet is connected to the air outlet of the pressure reducing device 42; the pressure regulating device 43 outputs a pilot pressure. The second channel 44 is used to transmit air.

[0175] The air inlet of the relay valve 45 is connected to the air outlet of the power source 41 and its air outlet is connected to the inlet of the second channel 44. The pilot port of the relay valve 45 is connected to the pressure regulating device 43.

[0176] Pressure sensor 46 is installed on the housing to detect the interaction force F0 between the door and the housing.

[0177] The controller is configured as follows:

[0178] Monitor the interaction force F0 between the door and the box;

[0179] When the interaction force F0 decreases and is less than the first preset interaction force, the pressure regulating device 43 is controlled to increase or maintain the pressure, and the relay valve 45 supplies air to the second channel 44 to reduce the interaction force.

[0180] By monitoring the interaction force F0 between the door and the cabinet, and controlling the pressure regulating device 43 to increase or maintain pressure when the interaction force F0 decreases and is less than a first preset interaction force, the relay valve 45 can generate air at a certain pressure to apply force to the door, causing the door to open. Furthermore, by monitoring the interaction force F0 between the door and the cabinet, the system identifies whether the user intends to open the door. A decrease in interaction force F0 indicates that the user has indeed made some movement towards the door, and a decrease in interaction force F0 indicates that the user has indeed intended to open the door. Therefore, increasing or maintaining pressure and outputting air from the relay valve 45 when the interaction force F0 decreases and is less than the first preset interaction force can prevent misjudgment of the user's opening intention, thus avoiding the door opening unnecessarily and improving the accuracy of the opening intention judgment, thereby enhancing the user experience.

[0181] In some embodiments of this application, if the user applies continuous force throughout the door opening process, and the interaction force F0 is detected to be 0 during the pressurization process, it indicates that the door has been opened.

[0182] If the user does not want to exert continuous force and simply wants to signal the dryer to open the door, they can apply force briefly and then release, waiting for the door opening assist module to work and open the door.

[0183] See Figures 8-11 In some embodiments, since the dryer needs to blow hot air into the drying drum to dry clothes, and the dryer also contains heat-generating loads such as motors and compressors that require heat dissipation, the dryer also includes an auxiliary air supply module. This auxiliary air supply module is located inside the housing and is used to supply air into the drying drum and / or to the heat-generating loads.

[0184] See Figures 10-11 The auxiliary air supply module includes a power source 41, which provides compressed air. The power source 41 of the auxiliary air supply module and the power source 41 of the auxiliary moving module 4 can share the same power source, and the compressed air is delivered to the auxiliary moving module 4 and the auxiliary air supply module respectively through two flow paths from the power source 41.

[0185] The auxiliary air supply module also includes an air supply pressure reducing device 61, which is used to reduce the pressure of the air flowing through it. The air inlet of the air supply pressure reducing device 61 is connected to one of the air outlets of the power source, so that the air supply pressure reducing device 61 can reduce the pressure of the air flowing out of the power source and output the reduced air.

[0186] The auxiliary air supply module also includes an air supply speed control device 62, which is used to regulate the airflow. The air inlet of the air supply speed control device 62 is connected to the air outlet of the air supply pressure reducing device 61, and the air supply speed control device 62 outputs a pre-controlled flow rate. The maximum pressure flowing to the air supply speed control device 62 is adjusted by the air supply pressure reducing device 61.

[0187] The auxiliary air supply module also includes a drying air device and a load heat dissipation device. The drying air device is used to deliver the air supplied to it into the drying cylinder. The load heat dissipation device is used to deliver the air supplied to it to the heat-generating load. The load heat dissipation device includes a heat dissipation diffuser 77, which is a funnel-shaped diffuser that enlarges the lateral area of ​​the heat dissipation air supply, allowing the air to dissipate heat from the motor, compressor, and other heat-generating loads.

[0188] The auxiliary air supply module also includes a reversing solenoid valve 74. When the reversing solenoid valve 74 is energized, it connects to the load heat dissipation device and disconnects from the drying air device; when the reversing solenoid valve 74 is de-energized, it connects to the drying air device and disconnects from the load heat dissipation device.

[0189] The auxiliary air supply module also includes an air supply relay valve 66. The air inlet of the air supply relay valve 66 is connected to the air outlet of the power source, and the air outlet of the air supply relay valve 66 is connected to the inlet of the reversing solenoid valve 74. The pilot port of the air supply relay valve 66 is connected to the air supply speed control device 62. The air supply relay valve 66 receives the pre-controlled flow rate output by the air supply speed control device 62, amplifies the flow rate according to the pre-controlled flow rate, and outputs driving air to the reversing solenoid valve 74.

[0190] The airflow output by the air supply speed control device 62 to the drying air device or the load heat dissipation device is controlled by adjusting the pre-controlled flow rate output by the air supply speed control device 62.

[0191] In related technologies, a motor typically drives a fan to rotate, propelling airflow into the drying drum to dry clothes. However, this method binds the motor speed to the fan speed, making it impossible to achieve more reasonable and flexible airflow control. Furthermore, the dryer contains heat-generating loads such as a motor and compressor, and related technologies include a cooling fan to dissipate heat. However, this cooling fan requires a separate control interface on a circuit board, has a fixed airflow speed, and is relatively expensive. Moreover, the cooling fan cannot adjust the airflow speed based on the load temperature.

[0192] This application achieves drying and load cooling functions by supplying air to the drying air device and the load heat dissipation device through a power source, saving the need for a cooling fan and reducing costs. This application can independently control and adjust the output air speed by adjusting the pre-controlled flow rate output by the air supply speed control device 62, reducing the motor load while making the air speed flowing into the drying cylinder more reasonable and adjustable.

[0193] In some embodiments of this application, the power source may be a pump body, wherein the power source may be a small pump.

[0194] In some embodiments of this application, the air supply pressure reducing device 61 is a pressure reducing valve.

[0195] The auxiliary switch module also includes a first wind speed sensor 67 and a second wind speed sensor 68.

[0196] The first wind speed sensor 67 is used to detect the airflow speed between the reversing solenoid valve 74 and the load heat dissipation device and record the detected flow speed as the first flow speed.

[0197] The second wind speed sensor 68 is used to detect the air flow rate between the air outlet of the air supply relay valve 66 and the drying air device and to record the detected flow rate as the second flow rate.

[0198] The dryer also includes a controller, which is configured to:

[0199] The pre-controlled flow rate output by the air supply speed regulating device 62 is adjusted based on the difference between the detected first flow rate and the preset wind speed value, or the difference between the second flow rate and the preset wind speed value. By adjusting the pre-controlled flow rate output by the air supply speed regulating device 62, the air speed output by the air supply speed regulating device 62 to the drying air device or the load heat dissipation device reaches the preset wind speed value, thereby maintaining the air speed output to the drying air device or the load heat dissipation device in a preset constant state.

[0200] In some embodiments of this application, the auxiliary air supply speed control device 62 includes a third solenoid valve 63 and a fourth solenoid valve 64.

[0201] The inlet of the third solenoid valve 63 is connected to the outlet of the pressure reducing valve.

[0202] The inlet of the fourth solenoid valve 64 is connected to the outlet of the third solenoid valve and the pilot port of the air supply relay valve 66.

[0203] When the airflow speed of the air supply relay valve 66 to the reversing solenoid valve 74 is in the air intake state, the air supply relay valve 66 increases the airflow speed supplied to the drying air device or the load heat dissipation device. At this time, the third solenoid valve 63 and the fourth solenoid valve 64 are de-energized.

[0204] When the air supply relay valve 66 is in constant flow mode to the reversing solenoid valve 74, the air supply relay valve 66 supplies air to the drying air device or the load heat dissipation device at a constant speed. At this time, the third solenoid valve 63 is de-energized and the fourth solenoid valve 64 is energized.

[0205] When the airflow speed from the air supply relay valve 66 to the reversing solenoid valve 74 is in a windless state, the air supply relay valve 66 does not supply air to the drying air device or the load heat dissipation device. At this time, the third solenoid valve 63 and the fourth solenoid valve 64 are energized.

[0206] The connection and disconnection of the third solenoid valve 63 are controlled by energizing and de-energizing it, and the disconnection and connection of the fourth solenoid valve 64 are controlled by energizing and de-energizing it.

[0207] The outlet of the fourth solenoid valve 64 is connected to other devices or is open.

[0208] The third solenoid valve 63 and the fourth solenoid valve 64 are two-position three-way solenoid valves.

[0209] In some embodiments of this application, the air supply speed control device 62 further includes an air supply flow regulator 65, wherein the inlet of the air supply flow regulator 65 is connected to the air supply pressure reducing device 61, and the air supply flow regulator 65 is used to control the flow rate in the flow path between the air supply speed control device 62 and the pilot port of the air supply relay valve 66. Since the air supply relay valve 66 has the function of amplifying the flow rate, the regulation of the flow path between the air supply speed control device 62 and the pilot port of the air supply relay valve 66 is for the purpose of regulating the output flow rate of the air supply relay valve 66.

[0210] Among them, the air flow regulator 65 can be a throttle valve.

[0211] In some embodiments of this application, the auxiliary air supply module further includes an air supply path pressure control device 69. The inlet of the air supply path pressure control device 69 is connected to an air outlet of the power source. The air supply path pressure control device 69 is used to control the air pressure in the flow path between the air outlet of the power source and the air supply pressure reducing device 61 to be lower than its overflow pressure.

[0212] The air supply pressure control device 69 is an overflow valve, wherein the inlet of the overflow valve is connected to the air outlet of the power source, and the outlet of the overflow valve is connected to other devices or is open.

[0213] In some embodiments of this application, the auxiliary air supply module further includes a one-way air supply device 70, which is used to prevent air backflow. The inlet of the one-way air supply device 70 is connected to the air outlet of the power source, and the outlet of the one-way air supply device 70 is connected to the air pressure reducing device 61.

[0214] Among them, the one-way air supply device 70 is a one-way valve.

[0215] In some embodiments of this application, the auxiliary air supply module further includes an emergency air supply exhaust device 71, which is used to cut off the air flow path between the power source, the air supply pressure reducing device 61, and the air supply relay valve 66.

[0216] In the event of a malfunction in the air supply circuit that causes a continuous flow of air to the drying air device or the load heat dissipation device, the air supply emergency exhaust device 71 can be used to cut off the air supply circuit and simultaneously vent the air away from the power source side of the air supply emergency exhaust device 71.

[0217] Among them, the emergency ventilation device 71 can be a shut-off valve.

[0218] In some embodiments of this application, the auxiliary air supply module further includes an air supply filter 73, which is connected to the air inlet of the air supply speed control device 62 and the air inlet of the air supply relay valve 66 on the side near the power source. The air supply filter 73 is used to filter impurities in the air to ensure the purity of the gas.

[0219] Among them, the air supply filtration device 73 can be a filter.

[0220] In some embodiments of this application, the auxiliary air supply module also includes a backup air supply device 72. When the power source fails, the backup air supply device can replace the power source pump for a period of time, improving the device's durability and making up for the gap before after-sales service.

[0221] The backup air supply device 72 can be an air storage tank of a certain volume.

[0222] The power source compresses air into the main air circuit, and the air pressure in the main air circuit is set by the air supply pressure control device 69. After passing through the air supply filter 73, the air in the main air circuit is divided into two paths, flowing into the air supply pressure reducing device 61 and the air supply relay valve 66 respectively. The set pressure P4 of the air supply pressure reducing device 61 serves as the duct pressure of the air supply speed regulating device 62, which outputs a pre-controlled flow rate to the pilot port of the air supply relay valve 66. The air supply relay valve 66 receives the pre-controlled flow rate output by the air supply speed regulating device 62, amplifies the flow rate according to the pre-controlled flow rate, and outputs driving air to the reversing solenoid valve 74.

[0223] In some embodiments, the auxiliary air supply module further includes a fifth solenoid valve 75, which can be used to connect the load heat dissipation device and the drying air device.

[0224] When the fifth solenoid valve 75 is energized, the load cooling device is connected to the drying air device. When the fifth solenoid valve 75 is de-energized, the load cooling device is not connected to the drying air device.

[0225] By energizing and de-energizing the fifth solenoid valve 75, the load heat dissipation device and the drying air device can be simultaneously supplied with air or simultaneously not supplied with air.

[0226] In related technologies, a motor is typically used to drive fan blades to rotate, propelling airflow into the drying drum to dry clothes. However, this method binds the motor speed and fan blade speed together, making it impossible to achieve more reasonable and free wind speed control for the drying airflow.

[0227] Meanwhile, the dryer contains heat-generating loads such as a motor and compressor, and related technologies include a cooling fan to dissipate heat from these loads. However, the cooling fan requires a separate interface on a circuit board for control, has a fixed fan speed, and is relatively expensive. Furthermore, the cooling fan cannot adjust the airflow speed according to the load temperature.

[0228] refer to Figures 8-10To address the aforementioned issues, in some embodiments of this application, the drying drum 12 is provided with an air inlet 121 and an air outlet 122. Both the air inlet 121 and the air outlet 122 are connected to the clothing receiving cavity. During the drying process, the dryer 100 generates a drying airflow. This drying airflow enters the clothing receiving cavity through the air inlet 121, carries away moisture from the clothing, and exits through the air outlet 122. (Reference) Figure 1 In this embodiment, the air inlet 121 and the air outlet 122 are respectively located on the left and right sides of the drying cylinder 12, and the rotation of the drying cylinder 12 is achieved by a transmission mechanism consisting of a motor and a belt.

[0229] refer to Figures 8-10 The housing 1 contains air duct plates forming a drying air duct 11. The drying air duct 11 is located between the housing 1 and the drying cylinder 12. Both ends of the drying air duct 11 are connected to the air inlet 121 and air outlet 122 of the drying cylinder 12, respectively, forming a loop channel. A drying air device is connected inside the drying air duct 11. This device ensures that the air within the drying air duct 11 flows from the air outlet 122 to the air inlet 121, allowing air from the clothing storage cavity to enter the drying air duct 11 through the air outlet 122 and then enter the clothing storage cavity through the air inlet 121, thus achieving air circulation between the clothing storage cavity and the drying air duct 11. In this embodiment, the drying air device includes a drying air amplification device 76, which is flared in the shape of a trumpet. The drying air amplification device 76 can enlarge the lateral area of ​​the airflow, increasing the drying air volume.

[0230] In this embodiment, reference Figures 8-10 The drying air duct 11 includes a front air duct 111 connected to one side of the drying drum 12, a rear air duct 112 connected to the other side of the drying drum 12, and a lower air duct 113. The front air duct 111 and the rear air duct 112 are connected through the lower air duct 113. The drying air duct 11 is connected to the clothes receiving cavity to form a loop channel. (Reference) Figures 8-10 The arrow indicates the direction of air circulation within the loop channel.

[0231] refer to Figures 8-10 A drying device is installed inside the drying air duct 11. This device heats the condensed drying airflow, which is then introduced into the clothing receiving cavity through the air inlet 121. The drying device also condenses the high-temperature, high-humidity airflow exiting through the air outlet 122, removing moisture to form condensate. This cycle repeats, allowing the drying airflow to remove moisture from the clothes in the clothing receiving cavity, thus separating the moisture from the clothes and achieving the desired drying effect.

[0232] Specifically, reference Figures 8-10In this embodiment, the drying device is located in the lower air duct 113, and the drying device includes a condenser 142 and an evaporator 141. The compressor is used to compress the refrigerant so that the refrigerant flows into the condenser and the evaporator. The condenser 142 is located on the side of the evaporator 141 near the air inlet 121 on the drying cylinder 12. The condenser 142 is used to heat the air in the drying air duct 11 to form a high-temperature dry drying airflow. After passing through the drying air duct 11, the drying airflow enters the drying cylinder 12 and evaporates the moisture of the clothes to be dried in the drying cylinder 12 to form a high-temperature and high-humidity airflow. The high-temperature and high-humidity airflow exiting the drying cylinder 12 carries a lot of water vapor. After passing through the front air duct 111, it comes into contact with the low-temperature surface of the evaporator 141 in the lower air duct 113 and condenses water, becoming a low-temperature and low-humidity airflow. The low-temperature and low-humidity airflow is further heated by the condenser 142 to form a high-temperature dry drying airflow.

[0233] Since compressors and motors generate heat during prolonged operation, load cooling devices deliver air from the device to the heat-generating loads such as compressors and motors, thereby improving the heat dissipation effect of compressors and motors.

[0234] This application achieves drying and load cooling functions by supplying air to the drying air device and the load heat dissipation device through a power source, saving the need for a cooling fan and reducing costs; this application can independently adjust the wind speed, reducing the motor load while making the wind speed flowing into the drying drum more reasonable and adjustable.

[0235] In this embodiment, the working modes of the drying air device and the load heat dissipation device can be divided into four working states, and the control of airflow is accomplished by the third solenoid valve 63 and the fourth solenoid valve 64.

[0236] The controller is configured such that when the controller de-energizes the reversing solenoid valve 74, the fifth solenoid valve 75, the third solenoid valve 63, and the fourth solenoid valve 64, the auxiliary air supply module supplies air to the drying air device.

[0237] When the controller energizes the reversing solenoid valve 74, de-energizes the fifth solenoid valve 75, de-energizes the third solenoid valve 63, and de-energizes the fourth solenoid valve 64, the auxiliary air supply module supplies air to the load heat dissipation device.

[0238] When the controller controls the reversing solenoid valve 74 to be de-energized or energized, the fifth solenoid valve 75 to be energized, the third solenoid valve 63 to be de-energized, and the fourth solenoid valve 64 to be de-energized, the auxiliary air supply module supplies air to the drying air device and the load heat dissipation device.

[0239] When the controller controls the reversing solenoid valve 74 to be de-energized or energized, the fifth solenoid valve 75 to be de-energized or energized, the third solenoid valve 63 to be energized, and the fourth solenoid valve 64 to be energized, the auxiliary air supply module stops supplying air to the drying air device and the load heat dissipation device.

[0240] When the airflow speed from the air supply relay valve 66 to the reversing solenoid valve 74 is in the air intake state, the air supply relay valve 66 increases the airflow speed supplied to the drying air device or the load heat dissipation device, and at this time the third solenoid valve 63 and the fourth solenoid valve 64 are de-energized.

[0241] When the airflow of the air supply relay valve 66 to the reversing solenoid valve 74 is in constant speed mode, the air supply relay valve 66 supplies air to the drying air device or the load heat dissipation device at a constant speed. At this time, the third solenoid valve 63 is de-energized and the fourth solenoid valve 64 is energized. Since the airflow is automatically adjusted by the system at all times, the constant speed mode will be a temporary state and needs to be controlled and adjusted automatically.

[0242] When the airflow speed from the air supply relay valve 66 to the reversing solenoid valve 74 is in a windless state, the air supply relay valve 66 does not supply air to the drying air device or the load heat dissipation device. At this time, the third solenoid valve 63 and the fourth solenoid valve 64 are energized.

[0243] This application can realize four working modes of the drying air device and the load heat dissipation device through the above methods.

[0244] In some embodiments, when the airflow speed of the drying air device and the load heat dissipation device is not constant, a combination of three states—air intake, constant airflow, and no airflow—is required. For example, it can be continuously in the air intake state, or in an air intake-constant airflow-air intake-constant airflow cycle, or an air intake-constant airflow-no airflow-air intake-constant airflow-no airflow cycle, during which the airflow speed will decrease from high to low. The airflow speed can be set to be related to the proportion of time spent in the air intake, constant airflow, and no airflow states, allowing for stepless speed regulation.
