[0055] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0056] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0057] like Figure 1-Figure 6 As shown, the present invention provides an over-temperature safety control system for a gas-fired clothes dryer, comprising: an over-temperature safety control system body, wherein the over-temperature safety control system body comprises a controller 1 and a plurality of temperature sensors 2, and the over-temperature safety control system body is installed on a gas-fired clothes dryer 300, wherein the controller 1 is installed inside a clothes dryer housing 3 of the gas-fired clothes dryer 300 or on a front panel 30 of the clothes dryer housing 3, and the plurality of temperature sensors 2 are installed in the gas-fired clothes dryer 300 to detect whether the airflow temperature in the gas-fired clothes dryer 300 is abnormal;

[0058] During the use of the gas dryer 300 to dry clothes, several temperature sensors 2 detect whether the temperature of the high-temperature airflow in the gas dryer 300 is abnormal. If an abnormality occurs, a signal will be sent to the controller 1, and the controller 1 will adjust or shut down the gas dryer 300. If the abnormality occurs multiple times, the dryer will be shut down and an alarm will be issued. The temperature of the high-temperature airflow in the gas dryer 300 during the entire process is monitored in real time by the controller 1, and over-temperature safety control and protection are implemented throughout the entire process to ensure the effectiveness and safety of the drying process.

[0059] Exemplary Gas Clothes Dryer

[0060] like Figure 2 As shown, further, the present invention also provides a gas clothes dryer 300, in which the gas clothes dryer 300 of the structure is installed with the above-mentioned gas clothes dryer over-temperature safety control system, wherein the gas clothes dryer 300 of the structure includes a clothes dryer casing 3, a drying drum part 4, a burner fire grate 5, and a rear exhaust part 6. Specifically, the controller 1 is installed on the front panel 30 of the clothes dryer casing 3, and the drying drum part 4, the burner fire grate 5, and the rear exhaust part are installed in the clothes dryer casing 3;

[0061] The burner fire grate 5 is located at one side of the bottom of the drying drum part 4 and is connected to the drying drum part 4, while the rear exhaust part 6 is located at the rear side of the drying drum part 4 and is connected to the drying drum part 4. In addition, the burner fire grate 5 is connected to the rear of the dryer housing 3. Therefore, when the controller 1 electrically connects and starts the motor part 42 and the burner fire grate 5 in the drying drum part 4, the external air enters the burner fire grate 5 through the rear of the dryer housing 3, promoting the burner fire grate 5 to burn and generate airflow, and then the airflow enters the drying drum part 4. The drying drum part 4 rotates at this time to dry the clothes in the drying drum part 4, and then the airflow enters the rear exhaust part 6 and is discharged to the outside of the dryer housing 3, thereby realizing the drying process of the clothes by the gas dryer 300. The controller 1 and the plurality of temperature sensors 2 monitor the temperature of the whole process of the high-temperature airflow in the gas dryer 300 in real time, and the whole process of over-temperature safety control and protection ensures the effectiveness and safety of the drying process.

[0062] like Figure 3-Figure 4As shown, as shown, further, the above-mentioned clothes dryer housing 3 has a front partition 31, and the front partition 31 is located at the rear side of the front panel 30, and a drum opening 311 is opened on the front partition 31, and the drum opening 311 corresponds to the drying drum part 4, and clothes can be put into the drying drum part 4 through the drum opening 311; and a drum air inlet hole group 312 is opened on one side of the drum opening 311, and an air inlet cover plate 313 corresponding to the drum air inlet hole group 312 is also installed on the front partition 31, and a cavity is formed between the front partition 31 and the air inlet cover plate 313, and the cavity is connected with the burner fire grate 5, and the air inlet cover plate 313 provides a flow channel for the airflow generated by the combustion of the burner fire grate 5, so as to realize the airflow between the burner fire grate 5 and the drying drum part 4;

[0063] The above-mentioned several temperature sensing components 2 include an air inlet temperature sensor 21, where the air inlet temperature sensor 21 is installed in the above-mentioned cavity; the air inlet temperature sensor 21 detects the air flow temperature generated by the combustion in the burner fire grate 5. When the air flow temperature is abnormal, the controller 1 automatically controls the heating power of the burner fire grate 5 and appropriately adjusts or shuts down the fire after making a judgment based on the received temperature sensor signal. If the abnormality is repeated for multiple times, the controller will shut down and alarm.

[0064] Furthermore, the above-mentioned several temperature sensing components 2 also include an in-drum temperature sensor 22, which is installed on the inner surface of the front partition 31 to detect the temperature of the air flow entering the drying drum part 4. When the temperature is abnormal, the controller 1 receives the temperature sensor signal, makes a judgment, and automatically controls the burner fire grate 5 to appropriately adjust the heating power or turn off the fire. If the abnormality is repeated for many times, the machine will be shut down and an alarm will be issued.

[0065] Furthermore, a combustion chamber temperature control switch 51 is installed on one side of the burner fire grate 5. The combustion chamber temperature control switch 51 is a negative pressure abnormality temperature control switch. When the negative pressure in the burner fire grate 5 is abnormal, the airflow passing through the combustion chamber is insufficient to change the flame combustion direction, suppressing the flame, causing the combustion chamber temperature control switch 51 above the burner fire grate 5 to trip at high temperature, disconnecting the air intake valve 52 on one side of the burner fire grate 5, and shutting off the fire for protection. The above-mentioned air intake valve 52 is connected to the gas pipeline 50 through the joint module 7. Here, the joint module 7 replaces the nut connection method in the prior art to prevent the occurrence of gas leakage due to the crooked butt joint of the screw thread when the nut is rotated.

[0066] Exemplary rear exhaust

[0067] like Figure 5-Figure 6As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned rear end exhaust part 6, where the rear end exhaust part 6 of the structure includes a vortex housing 61 and a smoke exhaust pipe 62, wherein the vortex housing 61 is installed on the rear side of the drying drum part 4 and is connected to the drum body 41 of the drying drum part 4, and the smoke exhaust pipe 62 is installed on one side of the vortex housing 61, and the smoke exhaust pipe 62 is connected to the top plate 32 of the dryer shell 3, and a turbine blade member 611 is provided in the vortex housing 61, and the turbine blade member 611 is rotatably connected to the motor part 42 of the drying drum part 4, so when the motor part 42 is started, the turbine blade member 611 is driven to rotate, thereby driving the airflow to flow, and then the hot airflow generated by the combustion in the burner fire row 5 enters the drying drum part 4, and then enters the vortex housing 61, and then the turbine blade member blows the airflow to flow to the smoke exhaust pipe 62, thereby realizing the working process of the entire airflow, which is convenient for drying clothes.

[0068] Furthermore, the above-mentioned several temperature sensing components 2 also include an exhaust port temperature sensor 23, which is installed in the vortex housing 61 and corresponds to the smoke exhaust pipe 62. When the exhaust port temperature sensor 23 detects that the airflow temperature is abnormal, the controller 1 makes a judgment based on the received temperature sensor signal and automatically controls the burner fire grate 5 to appropriately adjust the heating power or shut down the fire. If the abnormality is repeated multiple times, the machine will be shut down and alarm will be issued.

[0069] Furthermore, a volute temperature control switch 63 is installed in the volute housing 61, and the volute temperature control switch 63 is a high temperature abnormal temperature control switch. Therefore, when the temperature in the volute housing 61 rises abnormally due to any fault, the volute temperature control switch 63 trips, so that the gas clothes dryer 300 is powered off, the air inlet valve 52 is disconnected, and the flame is turned off for protection.

[0070] Exemplary connector modules

[0071] like Figure 7-Figure 16 As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned joint module 7, where the joint module 7 of this structure includes a first joint part 71 and a second joint part 72. Here, the first joint part 71 is installed on the air intake valve 52, and the second joint part 72 is connected to the gas pipeline 50, so the first joint part 71 and the second joint part 72 can be directly connected simply and efficiently, thereby preventing gas leakage.

[0072] like Figure 7-Figure 9As shown, specifically, the first joint portion 71 of the structure here includes a joint base plate 711, a first external cap 712 installed on the joint base plate 711, and a first internal cap 713 is also provided in the first external cap 712. Correspondingly, the second joint portion 72 of the structure here includes a joint seat head 721, a second external cap 722 installed on the joint seat head 721, and a second internal cap 723 is provided in the second external cap 722. When the first joint portion 71 and the second joint portion 72 are connected, the first external cap 712 can be connected and installed between the second external cap 722 and the second internal cap 723. The first inner cap 713 can be connected to the second inner cap 723, and the second inner cap 723 has a first inner pre-tightening ring 724, and then the first inner pre-tightening ring 724 can be pressed against the joint seat plate 711, and correspondingly, the joint seat head 721 also has a second inner pre-tightening ring 725 that presses against the first inner cap 713. In this way, the external and internal external caps and internal caps are connected to each other, which can replace the nut connection method in the prior art, and the first inner pre-tightening ring 724 and the second inner pre-tightening ring 725 seal the inside to prevent the screw thread from being skewed when the nut is rotated, thereby preventing gas leakage.

[0073] Furthermore, a plurality of arc-shaped magnetic strips 729 are installed on the outer end of the second external cap 722, and correspondingly, an arc-shaped magnetic groove (not shown) corresponding to the arc-shaped magnetic strip is provided on the connector seat plate 711, so that when the second external cap 722 moves to contact the connector seat plate 711, the arc-shaped magnetic strip 729 enters the arc-shaped magnetic groove, thereby increasing the firmness between the second external cap 722 and the connector seat plate 711.

[0074] Exemplary blocking mechanisms

[0075] like Fig.10 As shown, further, in some embodiments of the present invention, a plurality of blocking mechanisms 73 are installed on the first external cap 712, and the plurality of blocking mechanisms 73 are evenly distributed on the first external cap 712. Specifically, the blocking mechanism 73 of the structure includes an inner blocking seat 731, a blocking rod 732, and an outer blocking seat 733, wherein a plurality of anti-sway grooves 714 are provided on the inner wall of the first external cap 712, and a blocking groove 715 is further provided in the anti-sway groove 714, and then the inner blocking seat 731 is installed in the blocking groove 715, and inner sliding strips 7311 are provided on both sides of the inner blocking seat 731, so as to facilitate the reciprocating sliding of the inner blocking seat 731 in the blocking groove 715;

[0076] The inner end of the blocking rod 732 passes through the first external cap 712 and extends to connect with the inner blocking seat 731, and an inner tightening spring 734 is provided on the blocking rod 732, and the inner tightening spring 734 abuts between the inner blocking seat 731 and the blocking groove 715. The second internal cap 723 is provided with an inner blocking seat 726 corresponding to the inner blocking seat 731. Therefore, when the first external cap 712 enters the second internal cap 723, the inner blocking seat 726 moves along the anti-sway groove 714, thereby preventing the first external cap 712 and the second internal cap 723 from rotating relative to each other during installation, so that the second internal cap 723 can efficiently enter the first external cap 712.

[0077] When the locking cam 732 is in the unlocking state, the locking cam 734 is in the unlocking state, and the locking cam 734 is in the unlocking state, so that the locking cam 732 is locked.

[0078] Exemplary Outer Blocking Cap

[0079] like Figure 11-13 When the locking cam 732 is in the unlocking state, the locking cam 732 is locked and the locking cam 732 is locked.

[0080] like Figure 14-16As shown, further, there is an outer top seat 744 corresponding to the outer blocking seat 733 on the other side of the inner end of the second notch groove 741, and the outer blocking seat 733 has a third wedge sliding wall 736, and the outer top seat 744 has a fourth wedge sliding wall 745 corresponding to the third wedge sliding wall 736. Therefore, when it is necessary to open the first joint portion 71 and the second joint portion 72, the outer blocking cap 74 is rotated again, so that the blocking rod 732 is moved out of the first notch groove 728 and the second notch groove 741. When the locking cam 732 is in the unlocking state, the locking cam 732 is in the unlocking state, and the locking cam 732 is in the unlocking state, so that the locking cam 732 is unlocked and the locking cam 732 is unlocked.

[0085] Based on the position matching result and according to the component structural characteristics of the gas dryer, the safe operating temperature range of the area where each temperature sensor is located is obtained, and the relative size relationship between the pure personalized temperature sensor signal and the corresponding safe operating temperature range is compared in real time;

[0086] When there is a pure personalized temperature sensing signal that exceeds the corresponding safe use temperature range, the abnormal component structure is locked based on the position source of each temperature sensing component, and an independent short-cycle re-inspection instruction for the abnormal component structure is generated based on the controller;

[0087] Based on the short-cycle re-inspection instruction, the temperature sensor is controlled to re-sample the temperature signal of the abnormal component structure N times at different time nodes, and based on the re-sample results, the proportion of the N re-sample results exceeding the corresponding safe use temperature range is determined;

[0088] Control and warning unit for:

[0089] When the ratio exceeds a preset threshold, the abnormal component structure temperature is determined to be abnormal, and a first warning is sent to the management terminal;

[0090] At the same time, the temperature of the abnormal component structure is tracked in real time, and when the temperature abnormality frequency of the abnormal component structure exceeds the set threshold, the gas dryer is controlled to shut down, and a second warning is sent to the management terminal simultaneously.

[0098] In this embodiment, the preset threshold is set in advance, for example, it may be 50%, etc., and can be adjusted.

[0099] In this embodiment, the first warning refers to sending a warning to the management terminal that there is a temperature abnormality in the component structure.

[0100] In this embodiment, the threshold is set in advance, for example, it may be 5 consecutive abnormalities.

[0101] In this embodiment, the second warning refers to a notification sent to the management terminal after the abnormal component structure frequently has abnormal temperature and the gas dryer is shut down.

[0102] The working principle and beneficial effects of the above technical solution are: by constructing a parallel communication link between each temperature sensor and the controller, the personalized temperature sensor signal monitored by each temperature sensor is transmitted to the controller in real time and effectively, providing reliable data support for the over-temperature safety control of the gas dryer. Secondly, the received personalized temperature sensor signal is processed and analyzed to lock the currently existing abnormal component structure, and at the same time, an independent short-cycle re-inspection instruction for the abnormal component structure is generated to realize N times of temperature signal re-sampling of the abnormal component structure at different time nodes, which provides convenience for determining whether it is indeed abnormal. Finally, the re-sampling results are analyzed to accurately lock the temperature anomaly of the abnormal component structure. At the same time, the abnormal component structure is tracked in real time to achieve shutdown of the gas dryer when the frequency of temperature anomalies of the abnormal component structure exceeds the set threshold, thereby ensuring the safety and reliability of the gas dryer and improving the intelligence and accuracy of the control of the gas dryer.

[0104] The parameter determination subunit is used to:

[0105] Based on the first warning result, a current real-time temperature signal of the abnormal component structure is obtained, and a deviation value of the real-time temperature signal relative to a safe operating temperature range is determined;

[0107] A control preparation subunit is used to determine the relationship function between the temperature sensor signal and the gas consumption when the gas clothes dryer is working based on the factory configuration parameters of the gas clothes dryer, and analyze the target deviation value based on the relationship function to obtain the optimal adjustment amount of the current gas amount of the gas clothes dryer;

[0111] Performing a second control on the gas valve in sequence based on the step adjustment amount, and obtaining a target temperature signal adjusted by each step adjustment amount in sequence based on the second control result;

[0112] If the target temperature signal meets the safe operating temperature range, the step adjustment is skipped and the real-time sensor temperature of each component structure of the gas dryer is continuously monitored;

[0113] At the same time, the minimum gas demand of the gas dryer when it is working is determined based on the factory configuration parameters of the gas dryer, and when the gas supply is adjusted in steps to be lower than the minimum gas demand, the gas dryer is forced to shut down and a shutdown warning is issued simultaneously.

[0114] In this embodiment, the deviation value refers to the degree to which the current real-time temperature signal of the abnormal component structure exceeds the safe operating temperature range.

[0119] In this embodiment, the relationship function is used to characterize the relative change relationship between the temperature sensor signal and the gas consumption when the gas clothes dryer is working.

[0120] In this embodiment, the optimal adjustment amount refers to the adjustment value of the current gas amount of the gas clothes dryer when the target deviation value is reduced to the minimum, that is, maintaining the operating temperature of the gas clothes dryer at the maximum effect without affecting safety.

[0121] In this embodiment, the adjustment opening refers to a parameter of the degree of adjustment of the gas valve.

[0122] In this embodiment, the first control refers to controlling the gas valve according to the obtained adjustment opening.

[0123] In this embodiment, the step adjustment amount refers to the adjustment amount of the gas amount that is increased sequentially on the basis of the optimal adjustment amount, that is, the gas supply amount of the gas dryer is decreased sequentially.

[0124] In this embodiment, the second control refers to controlling the gas valve according to the determined step adjustment amount, that is, controlling the gas supply to the gas clothes dryer by changing the opening degree of the gas valve.

[0125] In this embodiment, the target temperature signal refers to the current real-time temperature signal of the abnormal component structure after each control.

[0126] In this embodiment, the minimum gas demand refers to the minimum gas demand required for the gas clothes dryer to work, that is, the gas clothes dryer will not work if the gas demand is lower than this value.

[0127] The working principle and beneficial effects of the above technical solution are: by determining the deviation value between the current real-time temperature signal of the abnormal component structure and the safe use temperature range, and correcting the deviation value according to the working dependency relationship and temperature transfer coefficient between the structural components, the optimal adjustment amount of the current gas volume of the gas dryer is determined according to the corrected deviation value; secondly, the opening of the gas valve is controlled according to the obtained optimal adjustment amount of the gas volume, and the real-time temperature signal of the abnormal component structure is tracked after the control, so that when the temperature warning of the abnormal component structure cannot be released after the gas volume is controlled, the step adjustment amount of the gas volume of the gas dryer is effectively determined; finally, the gas valve is controlled again according to the determined step adjustment amount, so as to ensure the working safety of the gas dryer; at the same time, when the step adjustment is such that the gas supply volume is lower than the minimum gas demand volume, the gas dryer is forced to shut down and the shutdown warning is issued simultaneously, so as to improve the control intelligence and reliability of the gas dryer and ensure the working effect of the gas dryer.
