As described in the background, during drying, the fan rotates to drive air into a circulating air flow within the drying module and drum. The air flow is changed into dry hot air after passing through the drying module and is blown to clothes in the drum and takes away moisture, the wet hot air enters the condensing air duct and is subjected to heat exchange and mixing with condensed water flow, the steam in the air is liquefied and then is changed into cold air, and then the cold air is changed into dry hot air after passing through the fan and the heater and is blown to the drum, so that the purpose of drying the clothes is achieved. The flock generated in the drying process can enter the air duct of the drying module along with the air flow, and then is attached to the surfaces of the fan, the heater and other parts. If the flock cannot be cleaned in time, the air duct is possibly blocked, the overcurrent area is reduced, the air quantity is reduced, and the drying effect of clothes is affected. If the flock is excessively accumulated on the heater, open fire may be caused, and potential safety hazard exists.

In order to solve at least one of the problems in the prior art, namely to solve the problems that the filter screen is easy to block and the cleaning is time-consuming and labor-consuming due to the fact that the filter screen is trapped by the filter screen in the prior art, the utility model provides a condenser which comprises a main body, wherein a condensation air duct is formed in the main body, the main body comprises a separation section and an exhaust section along the air flow direction, an air inlet and an air inlet are arranged on the separation section, an air outlet is arranged on the exhaust section, the inner wall of the separation section is smoothly arranged, and the air inlet are arranged along the tangential direction of the inner wall of the separation section, so that air flow and water flow entering the separation section respectively form spiral air flow and spiral water flow along the inner wall of the separation section.

Under the condition of adopting the technical scheme, in the drying process of the condenser, the air flow blows the clothes in the drum, then carries part of moisture and thread scraps, enters the separation section through the air inlet, then spirally rises, and meanwhile, condensed water also enters the separation section through the water inlet and flows along the circumferential direction of the inner wall of the main body. The two are mixed, but the water is thrown to the wall surface by centrifugal force and then flows downwards, and the two are separated. The air flow flowing through the condenser not only realizes heat exchange, but also realizes the removal of filth. The condensed air flow enters the drying fan again through the exhaust section and becomes dry hot air to enter the cylinder body for working, and the effect of drying clothes is achieved through reciprocating circulation.

The condenser of the present utility model will be described in detail with reference to fig. 1 and 2. Fig. 1 is a structural view of a condenser body according to the present utility model, and fig. 2 is a right side view of the condenser body according to the present utility model.

As shown in fig. 1 and 2, in a preferred embodiment, the condenser includes a main body 1, a condensation duct is formed inside the main body 1, the main body 1 includes a separation section 12 and an exhaust section 11 along the air flow direction, the section of the separation section 12 is circular, an air inlet 121 and an air inlet 122 are provided on the separation section, an air outlet 111 is provided on the exhaust section 11, the inner wall of the separation section 12 is smoothly provided, and the air inlet 121 and the air inlet 122 are all arranged along the tangential direction of the inner wall of the separation section 12, so that the air flow and the water flow entering the separation section 12 form a spiral air flow and a spiral water flow along the inner wall of the separation section 12, respectively. Wherein the height of the water inlet 122 is not lower than the height of the air inlet 121. Preferably, the height of the water inlet 122 is higher than the height of the air inlet 121.

In the present utility model, the angle between the axial direction of the water inlet 122 and the plane of the cross section of the separator section 12 is between 0 ° and 90 °. Preferably, the angle is 45 °.

Further, the main body 1 further comprises a drainage section 13, the drainage section 13 is connected with the separation section 12 and is located at one end of the separation section 12 far away from the exhaust section 11, and a drainage outlet 131 is arranged on the drainage section 13.

In this way, by changing the angle between the axial direction of the water inlet 122 and the plane of the section of the separation section 12, that is, without using external force such as a pump body auxiliary device, in order to ensure that the condensed water can have different initial speeds after entering the separation section 12 through the water inlet 122 by changing the angle under the action of gravity, different movement tracks are generated, and different contact times with the air flow in the separation section 12 are finally achieved.

It will be appreciated by those skilled in the art that the height of the water inlet 122 is not lower than the height of the air inlet 121, which increases the likelihood of mixing the spiral water flow with the spiral air flow to a greater extent, although the water inlet 122 may not be positioned higher than the air inlet 121, although the degree of mixing and installation conditions of the water flow and air flow may be limited. In addition, the water discharge section 13 may be omitted, or the separation section 12 may be extended appropriately, and the water flow discharge function may be performed by the air inlet 121 of the separation section 12. In addition, the cross section of the separator section 12 may be oval in shape in addition to circular.

As a preferred embodiment, the air flow carrying the water vapor and the filth enters the separation section 12 of the condenser main body 1 from the air inlet 121, rises in rotation in the separation section 12 to form a spiral air flow, and the condensed water flows in from the water inlet 122, and since the air inlet 121 and the water inlet 122 are both arranged along the tangential direction of the inner wall of the separation section 12 and the water inlet 122 is arranged in a form of being inserted obliquely downwards into the separation section 12, the water flow enters the separation section 12 with an initial velocity under the action of gravity, and can fall in rotation along the inner wall surface of the separation section 12 to form a spiral water flow. Because the height of the water inlet 122 is above the height of the air inlet 121, the spiral airflow entering the separation section 12 can be fully contacted with the spiral water flow, in the process, the water vapor in the airflow is liquefied when being cooled, is thrown onto the inner wall surface of the separation section 12 in the rotating process, flows downwards along the inner wall surface under the action of gravity, and meanwhile, the filth is taken away by the water flow, so that the separation of the air and the water is realized, and the water flow flows into the drainage section 13 from the separation section 12 and finally flows out from the drainage outlet 131.

It should be noted that, in order to enable the airflow and the water flow to normally rotate after entering the separation section 12 and ensure the contact between the airflow and the water flow, the inner wall surface of the separation section 12 needs to be smoothly arranged to better form the spiral airflow and the spiral water flow, but this is not intended to limit the overall shape of the separation section 12, and the outer wall may be any shape, such as a cube column, but in view of the processing difficulty of the component and the convenience of subsequent installation and maintenance, the outer wall surface and the inner wall surface are kept consistent and are a preferred choice.

Referring now to FIG. 5, FIG. 5 is a schematic view of the direction of rotation of the air and water streams in the separation section of the present utility model.

As shown in fig. 5, the air inlet 121 and the water inlet 122 on the separation section 12 are provided so that the rotation direction of the spiral air flow is the same as the rotation direction of the spiral water flow.

Therefore, the air inlet and the water inlet are arranged to enable the rotation direction of the spiral air flow to be the same as that of the spiral water flow, so that the same motion state of the spiral air flow and the spiral water flow is maintained, the contact time of the spiral air flow and the spiral water flow is prolonged, the spiral air flow and the spiral water flow are fully contacted in the separation section 12, condensate water is enabled to act, a better condensation effect is achieved, and burrs are taken away by the water flow due to the full contact with the condensate water, so that the filtering effect of the condenser is improved. Of course, the two may be arranged with different rotational directions.

Referring back to fig. 2, further, the inner wall of the separation section 12 is tapered with a tapered cross-sectional area that increases gradually in the direction of gas flow.

That is, the section of the separation section 12 is circular, and the air flow enters the separation section 12 from the air inlet 121 to be converted into a rotation state, and the spiral air flow is more advantageous to rise due to the pressure difference because the taper of the separation section 12 is set to be a state of large upper and small lower.

It will be understood by those skilled in the art that fig. 2 only shows the case where the inner wall of the separation section 12 is in a cylindrical state of a straight cylinder with a wide upper part and a narrow lower part, and the cross section of the separation section 12 is circular, but this does not limit the scope of the present utility model, and there are various forms, for example, the separation section 12 is configured to be equally wide, or is configured to be a funnel shape with a wide upper part and a narrow lower part, so long as the same effect of spirally lifting the airflow can be achieved.

Referring now to fig. 3 and 4, fig. 3 is an assembly view of a drying apparatus and a laundry treating apparatus according to the present utility model; fig. 4 is a partial enlarged view of the drying apparatus according to the present utility model.

As shown in fig. 3 and 4, the present utility model further provides a drying device 2, where the drying device 2 includes, in addition to any one of the above condensers, a filter 22 and a drying fan 23, and the filter 22 is disposed in a drying air duct 21 of the drying device 2 and is located upstream of the heater, and in addition, drying module components such as a heater and a volute are disposed in the drying device 2.

In a preferred embodiment, firstly, the wet and hot air flow in the cylinder 4 enters the condenser main body 1 from the air inlet 121, secondly, the condensed dry air flow enters the drying air duct 21 through the air outlet 111 through the drying fan 23, the air flow is heated by the heater arranged in the drying air duct 21 and is converted into dry hot air flow, and as the front suction type filter 22 is arranged in the drying air duct 21 and positioned at the upstream of the heater, the residual filth in the dry hot air flow is cleaned again, so that the quantity of filth possibly attached to the surfaces of the drying module components such as the heater, the drying fan 23 and the like is reduced, and finally the dry hot air flow returns to the cylinder 4 for circulation operation. Therefore, the burrs are prevented from excessively accumulating in the drying module, and the safety of the drying device is improved.

The present utility model also provides a laundry treating apparatus including a drum 4 in addition to any one of the condensers or the drying devices of the above embodiments, an inner chamber of the drum 4 being communicated with an air inlet of the condenser main body 1, and an air outlet of the drying air duct 21 being also communicated with the inner chamber of the drum 4.

In a preferred embodiment, taking a drum-type washing and drying machine equipped with a drying device provided with a condenser as described above as an example, during drying, the drying fan 23 starts to drive the air flow, and after heating by the heater, hot dry air is generated, which then enters the drum 4 of the drum-type washing and drying machine, the laundry rolls in the drum 4, and after blowing through the laundry, a portion of moisture and lint is carried along by the hot dry air, which enters the separating section 12 of the condenser body 1 through the air inlet 121. Since the air inlet 121 is arranged tangentially to the separation section 12 and the inner wall of the separation section 12 is approximately circular in cross-section, the air flow after entering the separation section 12 thus forms a spiral air flow. Because the separation section 12 is tapered with a wide upper portion and a narrow lower portion, the gas flow is spirally increased in the separation section 12 by the pressure difference. At the same time, condensate enters the separation section 12 through the water inlet 122, and as the water inlet 122 is also arranged tangentially to the separation section 12, the condensate flow after the separation section 12 falls helically along the inner wall. The rotation directions of the two phases of water flow and air flow which are mixed together are the same, and due to obvious density difference between the two phases, moisture carried in the air flow is thrown onto the inner wall surface of the separation section 12 due to the centrifugal force in the process of mixing the two phases of air flow and water flow, then flows downwards along the inner wall surface of the separation section 12 under the action of gravity, and finally, the separation of the two phases of air and water is realized. By means of rotational flow movement of condensate water flow and air flow, heat exchange is completed between the two phases, water in the air phase flows downwards along with most of water flow after being liquefied by cooling to the drainage section 13, and burrs are transferred into the water flow from the air flow in the process, then the water flow which is collected with the condensate water, the liquefied water vapor and the burrs flows into the drainage pipe 3 through the drainage port 131 arranged on the drainage section 13, the drainage pipe 3 is connected with the cylinder 4 of the cylinder washing and drying integrated machine, so that the water flow is discharged into the cylinder 4 and finally discharged along with the water flow in the cylinder 4, and through the heat exchange and the removal of the burrs are realized by the air flow flowing through the condenser. The condensed air flow passes through the exhaust section 11 and enters the drying air duct 21 again under the action of the drying fan 23, becomes dry hot air through the heater, and then passes through the action of the filter element 21 to remove residual filth possibly existing again, and finally enters the cylinder 4 again to work, and the air flow is circulated repeatedly in such a way, so that the effect of drying clothes is finally achieved. In the drying process of the drum-type washing and drying integrated machine shown in fig. 3, automatic cleaning of the burrs in the drying process is realized, and the filter 22 arranged in the drying air duct 21 is matched, so that excessive accumulation of the burrs in the drying module is further avoided, the air quantity required by drying can be ensured, potential safety hazards possibly caused by accumulation of the burrs are eliminated, the user experience is improved, the reliability is improved, and the service life of the machine is prolonged.
