Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Some embodiments according to the invention are described below with reference to fig. 1 to 10.
Example 1:
the present embodiment proposes a heating detection device 10 for a laundry treatment device 20, the laundry treatment device 20 comprising a ventilation channel and a heating assembly 206, the heating detection device 10 comprising: a base plate 102 fixedly connected with the ventilation channel; a micro switch 104 fixedly connected to the substrate 102 and connected in series to the heating element 206; a rotating assembly 106, comprising: a cam 1062 rotatably connected to the base plate 102, and an air guide plate 1064 coaxially and fixedly connected to the cam 1062, wherein the air guide plate 1064 is disposed in the ventilation channel and rotates coaxially with the cam 1062; when the air deflector 1064 rotates to a preset position, the outer edge of the cam 1062 is slidably connected to the contact of the micro switch 104, and is communicated with the micro switch 104, so that the heating element 206 heats a preset target.
The laundry treating apparatus 20 in this embodiment is a dryer.
Fig. 1 shows a side view of a heating detection device 10 of the present embodiment; fig. 1 shows a front view of a heating detection device 10 of the present embodiment; FIG. 3 shows a cross-sectional view of section A-A of FIG. 2; fig. 4 shows a side view of the heating detection device 10 of the present embodiment; fig. 5 shows a front view of the heating detection device 10 of the present embodiment.
As shown in fig. 1 to 5, in the embodiment, the cam 1062 is rotatably connected to the base plate 102, the wind deflector 1064 is coaxially and fixedly connected to the cam 1062, and the wind deflector 1064 is disposed in the ventilation channel, so that when the fluid in the ventilation channel flows, the wind deflector 1064 can rotate coaxially with the cam 1062 under the action of the fluid, and therefore, the wind deflector 1064 rotates at different angles corresponding to different flow rates of the fluid in the ventilation channel. When the ventilation state of the ventilation channel is good, namely the flow in the ventilation channel is large, the air deflector 1064 rotates with a large amplitude under the action of the fluid and can keep a relatively stable position when the flow rate of the fluid in the ventilation channel is stable; when the flow rate in the ventilation channel is small, the air deflector 1064 is close to a natural sagging state under the action of the self-gravity and the fluid in the ventilation channel. In the process of rotating the air deflector 1064, the cam 1062 and the air deflector 1064 rotate coaxially, so the rotation angle of the cam 1062 also depends on the flow rate of the fluid in the ventilation channel, after the flow rate of the fluid in the ventilation channel reaches a preset value, the air deflector 1064 rotates to a preset position, the cam 1062 rotates to the preset position along with the air deflector 1064, the outer edge of the cam 1062 is slidably connected with the contact of the micro switch 104, at this time, the micro switch 104 is communicated, the circuit where the heating element 206 connected in series with the micro switch 104 is located is communicated, and the heating element 206 heats a preset target.

It should be noted that the angle of rotation of the air deflector 1064 depends on the gravity of the air deflector 1064 itself, the shape of the air deflector 1064, and the flow rate of the fluid in the ventilation channel, and the shape of the outer edge of the cam 1062 determines the preset position of the air deflector 1064 when the micro switch 104 is connected, so that the shape and the mass of the air deflector 1064 and the profile of the outer edge of the cam 1062 determine the preset value of the fluid when the micro switch 104 is connected, and compared to different preset values in different clothes dryers, one or more of the shape and the mass of the air deflector 1064 and the outer edge of the cam 1062 can be changed to meet the use requirement. Preferably, the different preset positions of the air deflector 1064 are adjusted by replacing different cams 1062, so as to adjust the preset value of the flow rate.

When the ventilation state of the ventilation channel is good, namely the flow in the ventilation channel is large, the air deflector 1064 rotates with a large amplitude under the action of the fluid and can keep a relatively stable position when the flow rate of the fluid in the ventilation channel is stable; when the flow rate in the ventilation channel is small, the air deflector 1064 is close to a natural sagging state under the action of the self-gravity and the fluid in the ventilation channel. In the process of rotating the air deflector 1064, the cam 1062 and the air deflector 1064 rotate coaxially, so the rotation angle of the cam 1062 also depends on the flow rate of the fluid in the ventilation channel, after the flow rate of the fluid in the ventilation channel reaches a preset value, the air deflector 1064 rotates to a preset position, the cam 1062 rotates to the preset position along with the air deflector 1064, the outer edge of the cam 1062 is slidably connected with the contact of the micro switch 104, at this time, the micro switch 104 is communicated, the circuit where the heating element 206 connected in series with the micro switch 104 is located is communicated, and the heating element 206 heats a preset target.
It can be understood that after the flow of the fluid reaches the preset value, the ventilation in the washing machine is good, and the heat generated by the heating component 206 in the washing machine can be smoothly taken away by the fluid, so that the temperature value in the washing machine is in a reasonable range; when the fluid flow does not reach the preset value, the ventilation state of the ventilation channel is poor at the moment, the heat generated by the heating component 206 cannot be discharged in time, the air deflector 1064 does not rotate to the preset position at the moment, the cam 1062 does not rotate to the position where the microswitch 104 is switched on, and the microswitch 104 is switched off, so that the heating component 206 stops working, the possibility of damaging clothes or even causing fire due to the fact that the washing machine cannot radiate heat in time is reduced, and the washing machine is safer in use.

When the ventilation state of the volute is good, namely the flow in the volute is large, the air deflector 1064 has large rotation amplitude under the action of the fluid and can keep a relatively stable position when the flow rate of the fluid in the volute is stable; when the flow rate in the volute is small, the air deflector 1064 is close to a natural sagging state under the action of the self-gravity and the fluid in the volute. In the process of rotating the air deflector 1064, the cam 1062 and the air deflector 1064 rotate coaxially, so the rotation angle of the cam 1062 also depends on the flow rate of the fluid in the volute, after the flow rate of the fluid in the volute reaches a preset value, the air deflector 1064 rotates to a preset position, the cam 1062 rotates to the preset position along with the air deflector 1064, the outer edge of the cam 1062 is slidably connected with the contact of the microswitch 104, at this time, the microswitch 104 is communicated, the circuit where the heating assembly 206 connected in series with the microswitch 104 is located is communicated, and the heating assembly 206 heats a preset target.
It can be understood that after the flow of the fluid reaches a preset value, the fan has good ventilation, and the heat generated by the fan and the thermal assembly in the clothes dryer can be smoothly taken away by the fluid, so that the temperature value in the clothes dryer is in a reasonable range; when the fluid flow does not reach the preset value, the ventilation of the fan is poor, the heat generated by the heating component 206 in the clothes dryer can not be discharged in time, the air deflector 1064 does not rotate to the preset position at the moment, the cam 1062 does not rotate to the position where the microswitch 104 is switched on, and the microswitch 104 is switched off, so that the heating component 206 stops working, the possibility of danger caused by the fact that the clothes dryer can not radiate heat in time is reduced, and the clothes dryer where the fan is located is safer in use.

When the ventilation state of the ventilation channel is good, namely the flow in the ventilation channel is large, the air deflector 1064 rotates with a large amplitude under the action of the fluid and can keep a relatively stable position when the flow rate of the fluid in the ventilation channel is stable; when the flow rate in the ventilation channel is small, the air deflector 1064 is close to a natural sagging state under the action of the self-gravity and the fluid in the ventilation channel. In the process of rotating the air deflector 1064, the cam 1062 and the air deflector 1064 rotate coaxially, so the rotation angle of the cam 1062 also depends on the flow rate of the fluid in the ventilation channel, after the flow rate of the fluid in the ventilation channel reaches a preset value, the air deflector 1064 rotates to a preset position, the cam 1062 rotates to the preset position along with the air deflector 1064, the outer edge of the cam 1062 is slidably connected with the contact of the micro switch 104, at this time, the micro switch 104 is communicated, the circuit where the heating element 206 connected in series with the micro switch 104 is located is communicated, and the heating element 206 heats a preset target.
