Description

This device cleans the filter while ensuring the reliable operation of the ventilation system, effectively ensuring the air quality inside the building and improving the living experience of residents.

[0003] The boiling hot pot continuously produces water vapor, which will carry some oil molecules and disperse them in the indoor air. At the same time, frying and grilling meat will produce oil smoke, causing a large amount of oil molecules to be mixed in the indoor air. When the above-mentioned equipment is set up in a hot pot and barbecue restaurant for ventilation operation, the indoor air will be extracted. During the process, the oil molecules in the indoor air will adhere to the heat exchange surface of the heat absorption structure. After long-term use, a layer of oil and dirt will form on the heat exchange surface of the heat absorption structure. The oil and dirt layer will block the air from contacting the heat absorption structure, thereby reducing the heat exchange efficiency and further reducing the heat energy recovery effect of the air.

[0015] Beneficial effects:

[0016] 1. When the dirty air in the room is discharged by fan 1, the dirty air will flow through the heat exchange tube, and the heat in the dirty air will be collected by the heat exchange tube to realize heat energy recovery. At the same time, the cleaning liquid will be sprayed to the heat exchange surface of the heat exchange tube through the spray head to dissolve the oil layer on it into a mixed liquid. The mixed liquid will then be scraped off by square ring 2 to automatically clean the oil layer remaining on the heat exchange surface of the heat exchange tube, avoiding the problem of reduced heat energy recovery efficiency caused by the oil layer blocking the contact between the dirty air and the heat exchange tube;

[0017] Second, the fourth square ring and the U-shaped strip cooperate to intercept and guide the dripping mixed liquid, so that the mixed liquid flows along the front and rear sides of the fourth square ring and the U-shaped strip downward to the bottom of the inner side of the cavity one and gathers on the left side of the second square ring. This avoids the problem of mixed liquid droplets being blown to the right side of the second square ring due to dirty air, which makes cleaning difficult. During the cleaning process of the heat exchange cylinder, there is no need to shut down the first fan, and the ventilation operation can be carried out continuously.

[0018] 3. Most of the mixed liquid is intercepted by the long strip, so that only a small part of the mixed liquid will accumulate on the left side of the square ring 2, thereby greatly reducing the content of the mixed liquid accumulated on the left side of the square ring 2, thereby reducing the degree of interference with the contact between the cleaning liquid and the lower inner wall of the cavity 1. At the same time, when the mixed liquid flows through the limit block, it moistens the sponge block, and the sponge block uses the cleaning liquid in the mixed liquid to clean the oil layer at the contact position between the limit block and the cavity 1, which is beneficial to improve the cleaning effect. At the same time, by providing a groove on the sponge strip, the mixed liquid can stay in the groove of the sponge block when flowing through the sponge block, thereby improving the sponge strip's absorption effect on the mixed liquid, thereby improving the sponge block's cleaning effect on the oil layer.

[0033] The exhaust assembly includes a square tube 201, a fan 202, a filter 203 and a dust screen 204; the square tube 201 is bolted to the outer shell 1, the square tube 201 is in contact with the heat exchange tube 2, and the square tube 201 is fixed to the square ring 4; each cavity 91 is connected to the square tube 201; each square ring 6 is in contact with the square tube 201; four fans 202 are bolted to the square tube 201; four filters 203 are bolted to the square tube 201, and harmful substances in the air are absorbed by the filters 203; four dust screens 204 are bolted to the outer shell 1, and dust impurities in the air are intercepted by the dust screen 204.

[0034] The collection assembly includes a collection box 205 and a second dustproof net 206; the collection box 205 is detachably connected to the housing 1; the collection box 205 is bolted to a second dustproof net 206, and the dust impurities in the air are intercepted by the second dustproof net 206.

[0035] The air supply component includes a shell 207, a dustproof net 3 208, a filter 209 and a fan 2010; a shell 207 is arranged under the shell 1, and the shell 207 is made of plastic; a dustproof net 3 208 is bolted to both ends of the shell 207; the filter 209 is bolted to the inside of the shell 207; the fan 2010 is bolted to the inside of the shell 207.

[0036] The working principle of the above embodiment is as follows:

[0037] First, manually install the device on the wall of a building so that the left ends of the shell 1 and the shell 2 207 are both located indoors, and the right ends of the shell 1 and the shell 2 207 are both located outdoors. Connect the external heat exchange liquid circulation system to the two pipes 3 to complete the preparation operation. Start the fan 1 202 to make the indoor air flow to the right through the cavity 1 91 into the inner side of the square tube 201, and then flow to the right from the square tube 201 into the outdoor environment, thereby discharging the dirty air in the room. At the same time, start the fan 2 2010 to make the outdoor air flow to the left through the shell 2 207 into the room, thereby drawing fresh air from the external environment into the room, completing the ventilation operation. In this process, the air is cleaned by the cooperation of the filter element 1 203 and the filter element 2 209. The harmful substances in the air are filtered out, and the dust and other solid impurities in the air are intercepted by the cooperation of the dust-proof net 1 204, the dust-proof net 206 and the dust-proof net 3 208. When the dirty air in the room flows to the right in the cavity 1 91, it contacts the heat exchange cylinder 2. At this time, the heat exchange liquid is transported to the front pipe 3 through the external heat exchange liquid circulation system. The heat exchange liquid flows into the cavity 2 92 through the front pipe 3, and then flows back to the external heat exchange liquid circulation system from the rear pipe 3. In this process, the heat in the dirty air is transferred to the heat exchange cylinder 2, and then transferred to the heat exchange liquid through the heat exchange cylinder 2. The heat exchange liquid collects the heat in the external heat exchange liquid circulation system, realizing the automatic collection of heat in the dirty air while discharging the dirty air;

[0038] During the ventilation process, the rotation speeds of fan 1 202 and fan 2 2010 can be intelligently controlled by the program, thereby adjusting the ventilation intensity;

[0039] During the process of extracting indoor air, the dirty air in the room flows to the right in the cavity 1 91. After long-term use, a layer of oil and dirt will form on the inner wall of the cavity 1 91. Therefore, the fan 1 202 is turned off and the multi-stage telescopic rod 5 is started. The multi-stage telescopic rod 5 pushes the square ring 2 6 and the parts thereon to move to the left, so that the square ring 2 6 moves to the inside of the cavity 1 91, and the square ring 2 6 is tightly fitted with the heat exchange cylinder 2. At this time, the sprayer 9 delivers cleaning liquid to the square ring 3 7 through the hose. The cleaning liquid is sprayed onto the inner wall of the cavity 1 91 through the spray head 8, dissolving the oil and dirt layer on the inner wall of the cavity 1 91 to form a mixed liquid, and then the multi-stage The telescopic rod 5 drives the square ring 2 6 to continue to move to the left, scraping off the mixed liquid remaining on the inner wall of the cavity 1 91. The square ring 2 6 drives the parts on it to continue to move to the left, so that the spray head 8 always sprays the cleaning liquid onto the inner wall of the cavity 1 91 first to dissolve the oil layer into a mixed liquid, and the square ring 2 6 then scrapes off the mixed liquid. During the scraping process, the mixed liquid accumulates on the left side of the square ring 2 6. When the left side of the square ring 2 6 is flush with the left side of the heat exchange cylinder 2, the mixed liquid accumulated on the left side of the square ring 2 6 flows into the collecting box 205 for collection. After that, the collecting box 205 is manually removed and the mixed liquid in the collecting box 205 is cleared out.

[0040] According to the above working principle, we know that the present invention has the following effects:

[0041] During use, when the dirty air in the room is discharged by the fan 1 202, the dirty air will flow through the heat exchange tube 2, and the heat in the dirty air will be collected by the heat exchange tube 2 to realize heat energy recovery. At the same time, the cleaning liquid is sprayed to the heat exchange surface of the heat exchange tube 2 through the spray head 8 to dissolve the oil layer thereon into a mixed liquid, and then the mixed liquid is scraped off by the square ring 2 6, so as to automatically clean the oil layer remaining on the heat exchange surface of the heat exchange tube 2, thereby avoiding the problem of reduced heat energy recovery efficiency caused by the oil layer blocking the contact between the dirty air and the heat exchange tube 2.

[0042] Example 2

[0043] On the basis of Example 1, Figure 7 As shown, a square ring four 2011 is also included; each square ring three 7 is bolted with a square ring four 2011.

[0044] It also includes a U-shaped strip 2012; each square ring 2011 is welded with a U-shaped strip 2012, and the square ring 2011 and the U-shaped strip 2012 cooperate to prevent the mixed liquid from dripping, thereby avoiding the problem of difficult cleaning caused by the air blowing the dripping mixed liquid to the right side of the square ring 2 6.

[0045] The working principle of the above embodiment is as follows:

[0046] In the process of scraping the mixed liquid by the square ring 26 described in Example 1:

[0047] The scraped mixed liquid will drip downward along the left side of the square ring 2 6. If the fan 1 202 is in working condition, the airflow will drive the mixed liquid droplets to move obliquely to the right, that is, the mixed liquid droplets will fall to the right side of the square ring 2 6 in an inclined state, resulting in the square ring 2 6 being unable to push the mixed liquid falling to its right side into the collection box 205, resulting in incomplete cleaning of the mixed liquid, and it is difficult to manually clean the mixed liquid remaining on the inner side of the heat exchange cylinder 2. Therefore, while the square ring 2 6 is scraping the mixed liquid, the fan 1 202 continues to work to remove the dirty air in the room. The air is extracted. At this time, the mixed liquid flows on the upper side, front side and rear side of square ring three 7, and then flows to the upper side, front side and rear side of square ring four 2011. The mixed liquid on square ring four 2011 is intercepted by U-shaped strip 2012, so that the mixed liquid flows downward along the front and rear sides of square ring four 2011 and U-shaped strip 2012 to the bottom of the inner side of cavity one 91, and gathers on the left side of square ring two 6, thereby realizing continuous ventilation operation while cleaning heat exchange cylinder 2, without shutting down fan one 202.

[0048] According to the above working principle, we know that the present invention has the following effects:

[0049] During use, the square ring 4 2011 and the U-shaped strip 2012 cooperate to intercept and guide the dripping mixed liquid, so that the mixed liquid flows downward along the front and rear sides of the square ring 4 2011 and the U-shaped strip 2012 to the bottom of the inner side of the cavity 1 91 and gathers on the left side of the square ring 2 6, thereby avoiding the problem of difficult cleaning caused by dirty air blowing the mixed liquid droplets to the right side of the square ring 2 6. During the cleaning process of the heat exchange tube 2, there is no need to shut down the fan 1 202, and the ventilation operation can be carried out continuously.

[0050] Example 3

[0051] On the basis of Example 2, Figure 7-10 As shown, it also includes a long strip 2013 and a limit block 2014; each square ring four 2011 is bolted to a long strip 2013 on the lower side, and the long strip 2013 is in contact with the square tube 201; each long strip 2013 is fixedly connected to a limit block 2014 at both ends, and the limit block 2014 is in contact with the square tube 201, and the limit block 2014 is fixedly connected to the corresponding square ring two 6, and the limit block 2014 is fixedly connected to the corresponding square ring three 7; the upper side surface of the limit block 2014 is set to an inclined surface, and can also be set to an arc surface; the limit block 2014 is provided with a thickness surface 94.

[0052] It also includes a sponge block 2015; each limit block 2014 is fixed with a sponge block 2015, and the sponge block 2015 is in contact with the square tube 201.

[0053] It also includes a sponge strip 2016; each limit block 2014 is fixedly connected to a sponge strip 2016, and the sponge strip 2016 is fixedly connected to the corresponding sponge block 2015.

[0054] A groove 93 is formed on the sponge strip 2016 , wherein the groove 93 can be configured to be arc-shaped or V-shaped.

[0055] The working principle of the above embodiment is as follows:

[0056] In the process of scraping the mixed liquid by the square ring 26 described in Example 2:

[0057] The mixed liquid on the front, back and upper inner wall of cavity 1 91 will eventually gather on the left side of square ring 2 6, so that a relatively large amount of mixed liquid will gather on the left side of square ring 2 6. When the spray head 8 sprays the cleaning liquid to the lower inner wall of cavity 1 91, the excessive mixed liquid will block the cleaning liquid, resulting in the cleaning liquid being unable to directly contact the lower inner wall of cavity 1 91, thereby causing the oil layer on the lower inner wall of cavity 1 91 to be incompletely dissolved. Therefore, the mixed liquid on the front, back and upper inner wall of cavity 1 91 flows along the inner wall of cavity 1 91. When the front and rear sides of square ring 4 2011 and U-shaped strip 2012 flow downward, the long strip 2013 and the stopper 2014 cooperate to guide this portion of the mixed liquid to the left side of the long strip 2013. In other words, the long strip 2013 intercepts most of the mixed liquid, so that only a small portion of the mixed liquid accumulates on the left side of square ring 2 6. This significantly reduces the amount of mixed liquid accumulated on the left side of square ring 2 6, thereby reducing the degree of interference with the contact between the cleaning liquid and the lower inner wall of cavity 1 91.

[0058] The thickness surface 94 on the limit block 2014 contacts the inner wall of the cavity 1 91, which prevents the spray head 8 from spraying the cleaning liquid to the position where the limit block 2014 contacts the cavity 1 91, resulting in a poor cleaning effect on the oil layer there. Therefore, after the mixed liquid flows onto the limit block 2014, it contacts the sponge block 2015 and wets the sponge block 2015. Since the mixed liquid contains unreacted cleaning liquid, the square ring 2 6 drives the parts on it to move leftward, causing the sponge block 2015 to move leftward, applying the cleaning liquid to the position where the limit block 2014 contacts the cavity 1 91, dissolving the oil layer there.

[0059] After the mixed liquid flows onto the limit block 2014, due to the great uncertainty of the mixed liquid flow path, only a small amount of the mixed liquid will contact the sponge block 2015, resulting in insufficient absorption of the mixed liquid, and then resulting in insufficient cleaning liquid content in the sponge block 2015, and poor cleaning effect. Therefore, when the mixed liquid flows over the upper surface of the limit block 2014, it will contact the sponge strip 2016. During this process, part of the mixed liquid is absorbed into the sponge strip 2016 and then transferred to the sponge block 2015, so that the sponge block 2015 can fully absorb the mixed liquid to ensure the cleaning effect. At the same time, by providing a groove 93 on the sponge strip 2016, the mixed liquid can stay in the groove 93 of the sponge block 2015 when flowing through the sponge block 2015, thereby improving the sponge strip 2016's absorption effect on the mixed liquid, and then improving the sponge block 2015's cleaning effect on the oil layer.

[0060] According to the above working principle, we know that the present invention has the following effects:

[0061] When in use, when the mixed liquid flows downward along the front and rear sides of the square ring 4 2011 and the U-shaped strip 2012, the long strip 2013 and the limit block 2014 cooperate to guide this part of the mixed liquid to the left side of the long strip 2013, that is, the long strip 2013 intercepts most of the mixed liquid, so that only a small part of the mixed liquid will accumulate on the left side of the square ring 2 6, thereby greatly reducing the content of the mixed liquid accumulated on the left side of the square ring 2 6, thereby reducing the degree of interference with the contact between the cleaning liquid and the lower inner wall of the cavity 1 91, and at the same time, the mixed liquid When flowing through the limit block 2014, the sponge block 2015 is moistened. The sponge block 2015 uses the cleaning liquid in the mixed liquid to clean the oil layer at the contact position between the limit block 2014 and the cavity 91, which is beneficial to improving the cleaning effect. At the same time, by providing a groove 93 on the sponge strip 2016, the mixed liquid can stay in the groove 93 of the sponge block 2015 when flowing through the sponge block 2015, thereby improving the sponge strip 2016's absorption effect on the mixed liquid, and further improving the sponge block 2015's cleaning effect on the oil layer.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
