Example 4
Based on the embodiment 3, as shown in fig. 11-12, a humidifying component is further included; the humidifying component comprises a first guide plate 301, a second electric push rod 302, a third connecting rod 303, guide cloth 304, a second guide plate 305 and a water baffle 306; the conveying cylinder 1 and the collecting cylinder 6 are fixedly connected with two first guide plates 301 which are distributed left and right, and the first guide plates 301 are arranged to be of an inclined outward structure; the first guide plate 301 is provided with an air guide groove 301a; a plurality of second electric push rods 302 are respectively arranged on the outer side surfaces of the two liquid storage tanks 201, and the second electric push rods 302 are distributed along the bending curve of the liquid storage tanks 201; a third connecting rod 303 is fixedly connected to the telescopic part of each second electric push rod 302; all third connecting rods 303 on the left are fixedly connected with one guide cloth 304 together, all third connecting rods 303 on the right are fixedly connected with the other guide cloth 304 together, and one side of the guide cloth 304 close to the central line of the liquid storage tank 201 is obliquely arranged downwards; two guide cloths 304 are respectively positioned in the liquid storage tank 201 at the corresponding sides; the two liquid storage tanks 201 are fixedly connected with a second guide plate 305 through mounting rods respectively, and one side of the second guide plate 305, which is close to the central line of the liquid storage tank 201, is obliquely upwards arranged; the two liquid storage tanks 201 are respectively provided with a water baffle 306, and one side of the water baffle 306, which is close to the central line of the liquid storage tank 201, is obliquely upwards arranged; the part of the air sent by the air supply device is guided by the air guide groove 301a, the part of the air is guided to the upper surface of the guide cloth 304, the air is guided into the liquid storage tank 201 by the guide cloth 304 which is obliquely arranged downwards, the air is contacted with the moisture in the liquid storage tank 201, the part of the air containing the moisture is guided to the inner side of the evaporation tube 5 by the second guide plate 305 and the water baffle 306, the air humidity is increased, and the part of the air with high humidity is sent by the air supply device, so that the humidification purpose is achieved.
The water baffle 306 is made of soft materials, so that impact force generated by the water drops and the water baffle 306 can be reduced when the water drops carried by wind are blocked by the water drops, and the inner side of the splash and evaporation tube 5 is prevented from splashing after the water drops collide with the water baffle 306.
The defrosting and humidifying work of the invention is as follows:
because the refrigerating efficiency of the evaporating pipe 5 is very high, the temperature of the air around the evaporating pipe 5 is quickly reduced, and after a long time, the outer wall of the evaporating pipe 5 is in contact with water vapor in the air to generate a large amount of frost, and when the refrigerating operation is stopped, the part of frost can form water drops and drop into the space below the refrigerating equipment, so that the humidity of the space below is overlarge; therefore, when the evaporating tube 5 performs refrigeration, the second connecting rod 208 is driven to shrink by the telescopic part of the first electric push rod 202, so that the second connecting rod 208 drives the mounting frame 203, the scraping ring 204, the traction rope 209 and the connecting components thereof to move, then, the telescopic part of the first electric push rod 202 drives the second connecting rod 208 to push out, and the second connecting rod 208, the mounting frame 203, the scraping ring 204, the traction rope 209 and the connecting components thereof are restored to the initial state by the reset force of the spring 2010, so that the scraping ring 204, the scraping part 204a and the scraping plate 205 continuously scrape frost condensed by vapor, when the scraping ring 204, the scraping part 204a and the scraping plate 205 continuously scrape frost, a large amount of frost is scraped together to form water, and because of the triangular structure of the scraping part 204a and the scraping plate 205, the scraping part 204a and the scraping plate 205 scrape water to the outer sides of the evaporating tube 5 and the air extracting plate 103, and the air extracting plate 103 along with the evaporating tube 5 and the air extracting plate 103, and the water can be drained into the liquid draining box 201a quantitatively when the water draining box 201 is drained through the drain box 201.
While the mounting frame 203 reciprocates, the mounting frame 203 drives the first connecting rod 206 and the triangular scraping strip 207 to move, so that the triangular scraping strip 207 continuously scrapes the inner bottom surface of the liquid storage tank 201, and deposited ash generated on the inner bottom surface of the liquid storage tank 201 can be scraped in time, so that the ash removal effect is achieved.
When the indoor air is too dry and needs to be humidified, part of the air sent by the air supply device is guided by the first guide plate 301 and the air guide groove 301a, the part of the air is guided to the upper surface of the guide cloth 304, the air is guided into the liquid storage tank 201 by the guide cloth 304 which is obliquely downwards arranged, the air is contacted with the moisture in the liquid storage tank 201, the part of the air containing the moisture is guided to the inner side of the evaporation tube 5 by the second guide plate 305 and the water baffle 306, the air humidity is increased, and the part of the air with higher humidity is sent out by the air supply device, so that the humidification purpose can be achieved.
It should be noted that, in the process of guiding the part of the wind containing the moisture to the inside of the evaporation tube 5 through the second guide plate 305 and the water deflector 306, the water droplets scraped up by the wind can be blocked by the water deflector 306, preventing the water droplets from being guided to the inside of the evaporation tube 5 as well.
When the humidifying operation is not needed, the telescopic part of the second electric push rod 302 is controlled to drive the guide cloth 304 to move upwards near the central line side of the liquid storage tank 201, so that the side of the guide cloth 304 near the central line of the liquid storage tank 201 is changed from downward inclination to upward inclination, when wind is guided on the upper surface of the guide cloth 304 from the wind guiding groove 301a, the wind can be guided towards the outer side of the liquid storage tank 201 along the inclined surface of the guide cloth 304, so that the wind can not contact with the moisture in the liquid storage tank 201, and can not be guided to the inner side of the evaporating pipe 5 through the second guide plate 305 and the water baffle 306, and the part of wind does not contain moisture, so that the indoor humidity can be regulated through the state adjustment of the telescopic part of the second electric push rod 302 and the guide cloth 304.
