Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to fig. 6, the present embodiment provides a condensing system of a washing and drying integrated machine, which includes a condenser 1 and a spray head 2 disposed at a water inlet of the condenser 1; the spray head 2 is externally connected with a water inlet pipe 3, and the spray head 2 is provided with a plurality of first water spray ports 23 communicated with the interior of the condenser 1 and a plurality of second water spray ports 24 communicated with the exterior of the condenser 2. This embodiment utilizes and adds two kinds of different waterway structures on shower nozzle 2 of condenser 1, set up the water jet of two kinds of different water route flow directions promptly, make rivers in condenser 1 inside and outside homoenergetic evenly distributed, rivers are directly touched by shower nozzle 2 vertical whereabouts and with saturated vapor all the way, spout condenser 1 into by shower nozzle 2 all the way, make the outer wall contact of vapor and condenser 1, the direction and the heat exchange area of rivers have been increased simultaneously, thereby the condenser among the prior art has been solved, the problem that the water consumption is big under equal condensation heat transfer condition.

Specifically, as shown in fig. 1 to 2, the hot saturated water vapor in the washing and drying all-in-one machine barrel moves upward from the water vapor passage 4 at the bottom of the condenser 1, and at the same time, cold tap water is injected into the water inlet pipe 3 from the upper part of the condenser 1 for condensation. Tap water firstly enters the spray head 2 of the condenser 1, fills the inner space of the spray head 2, and then is uniformly distributed according to a specific water path structure (namely, a plurality of first water spray ports 23 and second water spray ports 24 arranged in the spray head 2). One path of the uniformly distributed water flow vertically falls from the second water spray opening 24 and is directly contacted with the rising saturated water vapor, the saturated water vapor is cooled, water in the saturated water vapor is separated out, the separated water vapor is unsaturated water vapor, the unsaturated water vapor is heated by a heating device arranged in the washing and drying all-in-one machine barrel to form saturated water vapor, and the water vapor is separated out again through the water vapor channel 4; the other path is sprayed into the condenser 1 through the first water spray 23, and is further dispersed through a specific condensation rib position 11 structure (namely, a plurality of condensation rib positions 11 which are arranged in a staggered manner) on the wall surface of the condenser 1, so that the path and the area of the water flow are increased. The condensing rib position 11 is formed in one step through blow molding, so that the processing technology is simplified, and the cost for processing a condensing system is reduced. Due to the structural characteristics of the condensation rib 11, a plurality of pits corresponding to the condensation rib 11 are formed on the outer wall surface of the condenser 1, and the pits disperse the water vapor ascending in saturation (namely, the motion state of the water vapor is influenced by the surface structure), so that the condensation contact area of the saturated water vapor is increased. Finally, the saturated rising water vapor and the downward sprayed cold tap water are subjected to heat exchange, liquid water is separated out from the saturated water vapor, falls back to the bottom of the washing and drying all-in-one machine barrel, and is discharged out of the washing and drying all-in-one machine through a drainage pump. The process is repeated, so that a stable and continuous condensation system is formed.

Specifically, as shown in fig. 3 to 6, the spray head 2 includes an upper cover 21 and a lower cover 22, wherein the upper cover 21 is provided with a water inlet column 212 connected to the water inlet pipe 3 and a first groove 211 communicated with the water inlet column 212. An upper linear waterway 213 communicating with the inlet column 212 and a plurality of upper communication chambers 214 communicating with the upper linear waterway 213 are provided in the first recess 211. When tap water enters the upper cover 21 of the nozzle 2 through the water inlet pipe 3 and the water inlet column 212, the tap water from the water inlet column 212 is firstly guided into the first groove 211 by the upper linear water channel 213 of the upper cover 21, and the plurality of upper communication cavities 214 are all provided with openings, so that the upper communication cavities 214 can effectively guide the tap water in the upper linear water channel 213 into the upper communication cavities.

Specifically, the nozzle 2 further includes a lower cover 22 clamped to the upper cover 21, the lower cover 22 is provided with a second groove 221 welded to the first groove 211, and an annular boss 222 provided on a lower surface of the lower cover 22. A lower straight water passage 223 corresponding to the upper straight water passage 213 and a plurality of lower communication chambers 224 corresponding to the upper communication chambers 214 are provided in the second groove 221 and the annular boss 222. The lower cover 22 is simply fixed with the upper cover 21 in a clamping manner, so that the connection manner is simplified, and meanwhile, in order to ensure the tightness of water flow, the first groove 211 of the upper cover 21 and the second groove 221 of the lower cover 22 are connected through a welding processing technology. In addition, the upper linear waterway 213 and the lower linear waterway 223 have the same structure, and can guide the tap water in the water inlet pipe 3 to the upper linear waterway; the lower communication chamber 224 is also provided with an opening, and can drain the water flow in the lower linear water passage 213. The positional relationship between the upper communication chamber 214 and the lower communication chamber 224 thus constitutes an integral communication chamber, which is also provided with an opening that allows tap water in the upper straight waterway 213 and the lower straight waterway 223 to be drained into the communication chamber (or the lower communication chamber 224).

Specifically, the first water jet 23 and the second water jet 24 are arranged on the annular boss 222 at intervals and are communicated with the lower communication cavity 224; the first water jet 23 is disposed on the sidewall of the annular boss 222, and the second water jet 24 is disposed on the bottom of the annular boss 222. Tap water drained to the lower communicating cavity 224 is uniformly distributed by the lower communicating cavity 224 which is uniformly distributed, a plurality of vertically downward openings (namely, second water spraying openings 24) which are arranged at intervals or in a separated mode are formed in the lower communicating cavity 224, and a plurality of openings (namely, first water spraying openings 23) which are arranged at intervals or in a separated mode and spray into the condenser 1 are formed, so that two different water path distribution modes can be guaranteed, heat exchange is carried out with saturated water vapor flowing through the water vapor channel 4, and the heat exchange area of water flow is increased. Specifically, since the vertically falling water flow in direct contact with the water vapor does not need to be so large, good heat exchange with the water vapor is possible. Based on this, it is preferable to set the number of the first water ejection holes 23 to be greater than the number of the second water ejection holes 24, thereby maximizing the efficiency of the heat exchange. In addition, the flow guiding structure 231 is extended outwards from the first water spraying opening 23, so that the guiding of the water flow can be ensured to be increased, and the uniform distribution of the water flow entering the condenser 1 is further increased.

Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
