[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 5 A cabinet-type gas clothes dryer convenient for use comprises a cabinet 1, a clothing cavity 2 with an opening on one side for hanging clothes is provided in the cabinet 1, a door leaf 3 capable of covering the opening on one side of the clothing cavity 2 is provided on one side of the cabinet 1, a heating installation cavity 4 is provided in the cabinet 1 below the clothing cavity 2, the heating installation cavity 4 is separated from the clothing cavity 2, and the bottom wall of the clothing cavity 2 is a partition separating the heating installation cavity 4 from the clothing cavity 2. The heating installation cavity 4 is provided with a gas access pipe 10, a burner assembly 5 capable of accessing the gas of the gas access pipe 10, and a hot air channel 6 which is in communication with the clothing cavity 2 and directs the heat generated by the burner assembly 5 to the clothing cavity 2, and the hot air channel 6 is an independent channel and is in communication with the clothing cavity 2 at one end. The left and right sides of the lower part of the clothing cavity 2 are respectively provided with a heat flow inlet 21 for hot air from the heating air channel 6 to enter the clothing cavity 2. The heat flow inlet 21 can be composed of multiple holes, for example, a mesh shape. The top of the clothing cavity 2 is provided with an exhaust fan 7 that can extract the air in the clothing cavity 2. The cabinet body 1 is provided with an exhaust channel 11 that can exhaust the air extracted by the exhaust fan 7. The heat flow inlet 21 is located at the bottom, and the exhaust fan 7 is located at the top. After the exhaust fan 7 is turned on, the hot air flows from the bottom to the top, allowing the heat to fill the clothing cavity 2 and make the heat uniform. A motor 71 is provided on the exhaust fan 7, and the motor 71 is a variable frequency motor. A gas proportional valve 41 for controlling the operation of the burner assembly 5 and a control board 8 for controlling the operation of the gas proportional valve 41 and the exhaust fan 7 are provided in the heating installation chamber 4. A first temperature sensor 22 that can give a control signal to the control board 8 is provided in the clothing chamber 2, and a humidity sensor 23 that can give a control signal to the control board 8 is provided in the exhaust passage 11. The control board 8 controls the speed of the motor 71 to switch between multiple gears according to the measured values ​​of the first temperature sensor 22 and the humidity sensor 23. The multiple gears refer to multiple speed value intervals of the motor 71. For example, the first gear is a speed of 1800-2000 rpm for the motor 71, the second gear is a speed of 1200-1500 rpm for the motor 71, and the speed of the motor 71 is 1000-1200 rpm. Of course, this is only the best embodiment, and other speed values ​​can also be used.

[0024] In order to facilitate control and ensure that clothes dry quickly, the best control scheme is that when the humidity sensor 23 detects that the humidity is greater than 60% or the first temperature sensor 22 detects a temperature of 70°C-80°C, the speed of the motor 71 is 1800-2000 rpm, which can be positioned as the first gear, and jumps to the next gear when the humidity is 60% or the temperature is 70°C; when the humidity sensor 23 detects that the humidity is 40% to 60% or the first temperature sensor 22 detects a temperature of 55-70°C, the speed of the motor 71 is 1200-1500 rpm, which can be defined as the second gear; when the humidity sensor 23 detects that the humidity is 20% to 30% and ...60% to 80°C, the speed of the motor 71 is 1500-2000 rpm, which can be defined as the second gear. When the temperature detected by the temperature sensor 22 is 35-55°C, the speed of the motor 71 is 1000-1200 rpm, which can be defined as the third gear; when the humidity sensor 23 detects that the humidity is 20% to 30% or the first temperature sensor 22 detects that the temperature is 20°C-35°C, the speed of the motor 71 is 800-1000 rpm, which can be defined as the fourth gear, or low gear; when the humidity sensor 23 detects that the humidity is less than 20%, the gas proportional valve 41 stops working, the burner assembly 5 stops working and extinguishes, and when the temperature detected by the first temperature sensor 22 is less than 20°C, the motor 71 stops working, and the clothes drying is completed. In order to prevent the burner assembly 5 from being overheated when it is ignited, the motor 71 is started before the burner assembly 5 is ignited. For example, the igniter of the burner assembly 5 starts to ignite ten seconds after the motor 71 is started.

[0025] In order to facilitate control and prevent the temperature from being too high, a second temperature sensor 26 for detecting the temperature at the heat flow inlet 21 is provided on the heat flow inlet 21. The heat flow inlets 21 on both sides are provided with second temperature sensors 26. The second temperature sensor 26 sends the detected temperature signal to the control board 8 for controlling the output pressure of the gas proportional valve 41, and controls the supply of gas according to actual needs to meet the workload. When the second temperature sensor 26 is just started, it is roughly the same as the room temperature, for example, 22°C. At this time, the gas supply of the gas proportional valve 41 is the largest, and the output pressure is the largest. As the temperature gradually increases, the gas proportional valve 41 reduces the output of the gas and reduces the output pressure of the gas to adapt to different workloads. For example, when the second temperature sensor 26 senses a temperature of 80°C-85°C, the gas proportional valve 41 begins to control the output pressure to decrease and reduce the flow of gas. When the humidity is still high, for example, when the humidity sensor 23 detects a humidity of 40% to 60%, and the temperature of the second temperature sensor 26 is lower than 60°C, the control board 8 controls the gas proportional valve 41 to increase the output pressure, increase the supply of gas, and increase the firepower. When the temperature of the second temperature sensor 26 is greater than 90° C., the control panel 8 controls the gas proportional valve 41 to close and extinguish the flame to prevent the clothes from catching fire.

[0026] To prevent burns and ensure that the burner assembly 5 does not work when the door leaf 3 is opened, a touch switch 12 is provided on the cabinet 1, which can send a signal to the control board 8 to control the gas proportional valve 41 to close when the door leaf 3 is opened. When the door leaf 3 is opened, the touch switch 12 pops up and disconnects, and the control board 8 receives the electrical signal to control the gas proportional valve 41 to close.

[0027] In order to make the heat uniform, the heat flow inlet 21 is a mesh provided at the bottom of the left and right side walls of the clothing cavity 2, the end of the hot air channel 6 extends to the left and right outer walls of the clothing cavity 2 and is connected to the mesh, the exhaust fan 7 is in the middle of the top of the clothing cavity 2, the heat enters from the left and right sides, the middle of the top of the clothing cavity 2 generates suction, the heat flows from the left and right sides to the middle and upward, so that the heat can be evenly diffused. The hot air channel 6 includes a horizontal section 61 extending to the left and right sides of the cabinet 1, and the two ends of the horizontal section 61 are provided with a vertical section 62 extending vertically, the upper end of the vertical section 62 is connected to the mesh, the horizontal section 61 and the vertical section 62 surround a channel separated from the heating installation cavity 4, the hot air channel 6 is a closed channel, the horizontal section 61 and the vertical section 62 can extend the hot air channel 6, prevent the heat temperature of the gas combustion from being too high, and make the heat uniform.

In order to control the cold air ratio, the area ratio of the cold air inlet mesh 52 to the area of ​​the hot flow inlet 21 is 0.4-0.5, so that the temperature at the hot flow inlet 21 can be effectively controlled not to be too high, and a certain amount of air can also be supplemented at the same time. The area of ​​the cold air inlet mesh 52 is 4500 square millimeters, and the hole area of ​​the hot flow inlet 21 is 9900 square millimeters. The cabinet 1 is provided with an air inlet mesh 13 at the bottom for air to enter the heating installation cavity 4, which is used to supplement the secondary air.
