A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figure 1-Figure 5 As shown, the present invention provides a fire extinguishing mechanism for a clothes dryer, comprising a water inlet bracket 1, a water inlet pipeline 2 and a plurality of nozzles 3. Figure 1 and Figure 2 As shown, the water inlet bracket 1 is placed behind the back plate 101 of the drum assembly 100, and a plurality of water inlet holes 102 are provided on the back plate 101. The water inlet bracket 1 has a flow channel 11 built therein; one end of the water inlet pipeline 2 is connected to the water inlet bracket 1, and the other end is connected to the water storage chamber of the dryer or directly to an external water channel. A plurality of nozzles 3 are placed on the side of the water inlet bracket 1 facing the back plate 101, and the plurality of nozzles 3 are connected to the flow channel 11, and can correspond one by one with the plurality of water inlet holes 102 to spray water into the drum assembly 100. In this embodiment, as Figure 5As shown, the spraying end of the nozzle 3 is spaced a certain distance from the water inlet hole 102 on the back plate 101 to prevent the nozzle 3 from interfering with the normal operation of the drum assembly 100. When a fire occurs in the drum assembly 100, the drum assembly 100 stops rotating, and the nozzle 3 is aligned with the water inlet hole 102 to spray water into the drum assembly 100 to achieve the purpose of fire extinguishing. The overall structure of the dryer fire extinguishing mechanism is simple, and the existing dryer equipment can be slightly modified to enable the dryer to have a fire extinguishing function. The water spray fire extinguishing method causes little damage to the dryer, and the dryer can be reused after the fire is extinguished, which solves the problem that the existing dryer does not have a fire extinguishing function.

[0042] Alternatively, if Figure 1 As shown, the water inlet bracket 1 of this embodiment is annular in structure as a whole and is axially arranged around the drum assembly 100. There are six nozzles 3 and six water inlet holes 102. The six nozzles 3 are evenly spaced along the circumference of the water inlet bracket 1 to improve the spray fire extinguishing effect.

[0043] Optionally, the fire extinguishing mechanism of the clothes dryer further includes a water inlet valve, the water inlet end of the water inlet valve is connected to the water storage chamber or the external water circuit, and the water outlet end of the water inlet valve is connected to the water inlet pipeline 2, for controlling the on-off of the water inlet pipeline 2. Under normal conditions, the water inlet valve is in a normally closed state, and the water inlet pipeline 2 is disconnected. When a fire occurs in the drum assembly 100, the water inlet valve is powered on and opened, and clean water enters the water inlet pipeline 2 through the water inlet valve to achieve spraying and extinguishing the fire.

[0044] Furthermore, in order to meet the water inlet pressure and prevent the water inlet pressure from failing to meet the use pressure of the water inlet valve and causing poor spraying fire extinguishing effect, when the water inlet valve of this embodiment is connected to the external water circuit, the water inlet pressure of the external water circuit should have a certain pressure, so that the spray water at the nozzle 3 has a strong water pressure impact force to ensure the best fire extinguishing effect. When the water inlet valve is connected to the water storage chamber of the dryer, a booster pump needs to be arranged between the water storage chamber and the water inlet valve to increase the water inlet pressure.

[0045] Furthermore, the present embodiment provides a clothes processing device, including a drum assembly 100, a drying mechanism and an upper clothes dryer fire extinguishing mechanism, the drying mechanism is a commonly used mechanism in the field, and can be a heat pump drying mechanism, the clothes dryer fire extinguishing mechanism is installed behind the back plate 101 of the drum assembly 100, and the drying mechanism is used to input drying air into the drum assembly 100. The clothes processing device has a fire extinguishing function, when a fire occurs in the drum assembly 100, the clothes dryer fire extinguishing mechanism can start to spray water on the drum assembly 100 to extinguish the fire, thereby improving product safety and ensuring the safety of users' lives and property.

[0046] Furthermore, if Figure 4 and Figure 5As shown, the clothing processing device further includes a driving assembly 200, which includes a bearing seat 201, a drum shaft 203 and a bearing group 204. The bearing seat 201 is circumferentially extended outward toward one end of the back plate 101 to form a positioning platform 202, and a plurality of nozzles 3 are arranged on the positioning platform 202, and the positioning platform 202 plays the role of supporting and fixing the nozzles 3. The drum shaft 203 is arranged in the bearing seat 201, and one end of the drum shaft 203 is fixedly connected to the back plate 101, preferably by welding, and the other end of the drum shaft 203 is fixedly connected to a tripod (not shown in the figure) of the clothing processing device, preferably by fasteners 207. The tripod is a common component in the art, and the tripod drives the drum assembly 100 to rotate synchronously through the drum shaft 203. The bearing group 204 is installed between the drum shaft 203 and the bearing seat 201, and is used to support the drum shaft 203, so as to improve the reliability and stability of the rotation process.

[0047] Furthermore, if Figure 4 and Figure 5 As shown, the drive assembly 200 also includes a shaft front flange 205 and a shaft rear retaining ring 206 for limiting the bearing group 204. Optionally, in this embodiment, the bearing group 204 includes a first bearing 2041 and a second bearing 2042 correspondingly mounted at both ends of the drum shaft 203, the inner circumference of the bearing seat 201 is correspondingly provided with a first assembly groove 2011 and a second assembly groove 2012, the first bearing 2041 and the second bearing 2042 are correspondingly assembled in the first assembly groove 2011 and the second assembly groove 2012, one end of the drum shaft 203 passes through the shaft front flange 205, the shaft front flange 205 is fixedly connected to the back plate 101, preferably welded, and the shaft front flange 205 abuts against the first bearing 2041 to limit the first bearing 2041. A slot 204 is circumferentially formed at the other end of the drum shaft 203 , and a rear retaining ring 206 is mounted in the slot 204 and abuts against the second bearing 2042 to limit the second bearing 2042 to achieve stable rotation of the drum shaft 203 .

[0048] Furthermore, the clothes processing device of this embodiment also includes a fire prevention mechanism, and the fire prevention mechanism includes a temperature sensor for monitoring the temperature in the drum assembly 100. Specifically, the temperature sensor includes two types of sensors, namely, a thermostat and a thermal resistor. The thermostat and the thermal resistor are commonly used components in the field. The thermostat has an automatic reset function, and the thermal resistor has a manual reset function. In this embodiment, the set safety temperature value of the thermal resistor is higher than the set safety temperature value of the thermostat. When the thermostat fails for some reason, the thermal resistor can still operate normally. Under normal circumstances, the safety temperature value set by the thermostat is the normal operating temperature that protects the normal operation of the machine from fire or combustion hazards. However, if an unexpected situation occurs, causing the temperature in the drum assembly 100 to exceed the set safety temperature value, the drying mechanism of the clothes processing device stops heating, and the fan of the drying mechanism continuously inputs low-temperature drying air into the drum assembly 100 to reduce the possibility of fire, avoid fire, and achieve the purpose of fire prevention. When the fire in the drum assembly 100 is extinguished, the device can be used again by manually resetting the thermal resistor, and the device will not be started again without human intervention.

[0049] Furthermore, if an open flame appears in the drum assembly 100 after the fire prevention mechanism supplies air for cooling, when a fire occurs, the smoke detector of the clothing processing equipment is activated, the drying mechanism is shut down as a whole, and the air inlet and outlet of the drying mechanism are closed at the same time to isolate oxygen. The fire extinguishing mechanism of the dryer is activated to spray water into the drum assembly 100 until the fire is extinguished, thereby achieving safety protection.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
