[detailed description of the invention]
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
The present invention realizes the function of original two water control valves realization by a water control valve and water tank, and as shown in fig. 1, this cloth drying device comprises condenser 0, also comprises water control valve 1 and water tank 2.In the present embodiment, water tank 2 is on the right side of condenser 0, but be not limited to this position and relation is set, in addition, it should be noted that, each parts in Fig. 1 all schematically show, not in order to limit the shape of each parts in actual state, such as condenser 0 schematically shows with section of a pipe, not in order to limit the condenser in actual state.
In Fig. 1, the top of water tank 2 is water inlet 3, and water control valve 1 is connected with water inlet 3.Water control valve 1 and water inlet 3 can adopt multiple connected mode, and such as water control valve 1 can be directly installed on water inlet 3, also can be connected with water inlet 3 by pipeline.Water can be controlled by water control valve 1 and inject water tank 2 by water inlet 3.
Water to inject water tank 2 process by water inlet 3 is controlled at water control valve 1, due to improper reasons such as pressure, aqueous reflux may be caused, if containing pollutant in the water flow backwards, just do not meet DVGW(Germany's combustion gas and water and wastewater industry association) test request, therefore, preferably, water tank can have passage 4, flow backwards to prevent water.Certainly, if do not consider DVGW test request, or other modes can be adopted to meet DVGW test request, also passage 4 can not be set.In FIG, passage 4 is arranged at the below of water inlet 3.
Water tank 2 has at least two delivery ports, for two delivery ports in Fig. 1, two delivery ports have certain difference in height, at this, delivery port higher for position is called the first delivery port 5, the lower delivery port in position is called that the second delivery port 6, first delivery port 5 is connected with condenser 0 all respectively with the second delivery port 6.Particularly, the first delivery port 5 can adopt integral structure to be connected with condenser 0 with the second delivery port 6, also can be connected by pipeline.
When there being water to inject water tank 2, because the position of the second delivery port 6 is lower, when water reaches the position of the second delivery port 6, water flows into condenser 0 to realize the refrigerating function to condenser 0 from the second delivery port 6.When water level is higher, when namely having more water injection water tank 2 to reach the position of the first delivery port 5, water flows into condenser 0 to realize the pre-washing function to condenser 0 from the first delivery port 5.
In order to need as far as possible few water when realizing the refrigerating function to condenser 0, as shown in fig. 1, the second delivery port 6 can be arranged on the bottom of water tank.In addition, the discharge usually needed than refrigerating function due to pre-washing function is much bigger, therefore, in embodiments of the present invention, the flow area of the first delivery port 5 can be made to be greater than the flow area of the second delivery port 6.Such as, if two delivery ports all adopt circular port, the aperture that so just can arrange the first delivery port 5 is greater than the aperture of the second delivery port 6, makes from the current of the second delivery port 6 outflow less, the current flowed out from the first delivery port 5 are comparatively large, with the requirement meeting cooling respectively and rinse.
In addition, also has a kind of implementation, even if the quantity of the first delivery port 5 is greater than the quantity of the second delivery port 6, such as, arrange 5 the first delivery ports 5, arrange second delivery port 6, flowing into the current of condenser 0 from the first delivery port 5 so also can be larger, the current flowing into condenser 0 from the second delivery port 6 are less, thus the requirement meeting cooling respectively and rinse.
Certainly, the flow area of the first delivery port 5 is greater than the flow area of the second delivery port 6, and the quantity of the first delivery port 5 is greater than the quantity of the second delivery port 6, and these two kinds of modes can adopt simultaneously.Flow area size and the quantity of concrete first delivery port 5 and the second delivery port 6 can be determined according to the actual amount of water demand of cooling water and wash water.
When needing to realize the refrigerating function to condenser 0, namely when the refrigerating function of condenser 0 is triggered, needing to control water control valve 1 uses a less unlatching rhythm to realize: open duration and be no more than V/ (m-m1), V be from the position of the first delivery port 5 to water tank 2 bottom water tank volume, m is the flow of water control valve 1, m1 is the flow of the second delivery port 6, and object makes the water level injecting water tank 2 be no more than the first delivery port 5, flows out from the first delivery port 5 to avoid water.Closedown duration is no more than the current complete required time in water tank 2, and object makes not produce cutout, ensures that the cooling water flowing into condenser 0 is as far as possible steady.
When needing to realize the pre-washing function to condenser 0, namely when the pre-washing function of condenser 0 is triggered, the unlatching duration controlling water control valve 1 is needed to ensure that water flows out from the first delivery port 5, the opening time of water control valve 1 such as can be made more than V/ (m-m1), when there being water in water tank 2, suitably can reduce flooding time, the concrete opening time can determine according to flushing demand.Such water flows out from the first delivery port 5, produces the comparatively mass-flow injecting condenser 0, thus realizes the pre-washing function to condenser 0.
Above-mentioned water control valve 1 is when selecting, and can select according to the opening size etc. of the concrete volume of water tank 2, the first delivery port 5 and the second delivery port 6, suggested range is 2 ~ 15L/min.
Refrigerating function is as one that controls condenser 0 important and meticulous function, and the more steady cooling effect of current is better.Fig. 2 is the comparison of one group of experimental data, and in fig. 2, what Line 1 type represented is adopt the mode in the present invention to adopt the water control valve of 10L/min by the current of the second delivery port 6 generation of water tank 2.The representative of No. 2 line styles be adopt mode of the prior art, when the water control valve realizing refrigerating function is 0.5L/min, the current of generation.The representative of No. 3 line styles be the current of ideal state, i.e. completely stable current.Visible, the current of the cooling produced during the mode in the present invention are adopted to fluctuate less, relatively completely stable current, if adopt the standard deviation of flow to characterize the fluctuation size of flow, the standard deviation of the current of the cooling that the mode so in the present invention produces is only 20% of the standard deviation of the cooling water stream that in prior art, mode produces, consistent level obtains significant lifting, the effect of refrigerating function can be ensured.
Visible, following advantage can be possessed by mode provided by the present invention:
1) water control valve is only needed can to realize cooling to condenser and pre-washing function.
2) owing to being carried out the current size of controlled cooling model by the second delivery port 6 of water tank, one can therefore be adopted compared with the water control valve of large discharge, the problem that the flow accuracy that can reduce like this to bring because of low discharge water control valve is poor.
3) consistent level of cooling water stream that mode provided by the present invention produces have also been obtained remarkable lifting, thus ensures the effect of refrigerating function.
