[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of household appliances, and more particularly, to a laundry drying apparatus and a method for controlling a condenser in the laundry drying apparatus.
[ background of the invention ]
In the clothes drying equipment, due to the drying function of clothes, the temperature in the clothes drying equipment is overhigh, so that a condenser is required to cool and remove water vapor, the condenser is generally divided into a water-cooled condenser and an exhaust condenser, and the invention relates to the water-cooled condenser, which will be called as the condenser for short in the following.
The control of the condenser mainly comprises cooling and flushing functions, wherein the cooling mainly adopts a smaller water flow to inject into the condenser, and under the condition of the same water consumption, the more stable the water flow, the better the cooling effect is. Since the flushing is to clean up impurities and deposits in the condenser, a large water flow is required to be injected into the condenser. In the existing clothes drying equipment, the cooling and flushing functions of the condenser are realized through two different water control valves, for example, when the cooling function is realized, a water control valve of 0.5L/min (liter/min) or 0.25L/min is adopted to achieve the required water flow by controlling the rhythm of a switch, and when the flushing function is realized, a water control valve of 10L/min or 8L/min is adopted to flush the condenser.
In the implementation mode in the prior art, two water control valves are required to be arranged, and the small-flow water control valve with the cooling function has the problems of poor flow precision and further influence on precision due to the fact that sediments are more easily formed in a high-temperature working environment.
[ summary of the invention ]
In view of the above, the present invention provides a laundry drying apparatus and a method for controlling a condenser in the laundry drying apparatus so as to perform cooling and rinsing functions of the condenser through a water control valve.

[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention realizes the functions realized by two original water control valves through one water control valve and a water tank, and as shown in figure 1, the clothes drying equipment comprises a condenser 0, a water control valve 1 and a water tank 2. In the present embodiment, the water tank 2 is arranged at the right side of the condenser 0, but is not limited to this position, and it should be noted that each component in fig. 1 is schematically illustrated and is not used to limit the shape of each component in the actual situation, for example, the condenser 0 is schematically illustrated by a length of pipe and is not used to limit the condenser in the actual situation.
In the figure 1, the top of the water tank 2 is provided with a water inlet 3, and the water control valve 1 is connected with the water inlet 3. The water control valve 1 and the water inlet 3 can adopt various connection modes, for example, the water control valve 1 can be directly installed on the water inlet 3 and can also be connected with the water inlet 3 through a pipeline. The water can be controlled to be injected into the water tank 2 through the water inlet 3 by the water control valve 1.
In the process that the water control valve 1 controls water to be injected into the water tank 2 through the water inlet 3, water may flow backwards due to abnormal reasons such as pressure, and if the water flowing backwards contains pollutants, the testing requirements of DVGW (German gas and Water industry Association) are not met, therefore, the water tank may preferably be provided with a vent 4 to prevent the water from flowing backwards. Of course, if the DVGW test requirement is not considered or can be satisfied in other ways, the vent 4 may not be provided. In fig. 1, the air vent 4 is provided below the water inlet 3.
The water tank 2 is provided with at least two water outlets, in fig. 1, two water outlets are taken as an example, the two water outlets have a certain height difference, the higher water outlet is referred to as a first water outlet 5, the lower water outlet is referred to as a second water outlet 6, and the first water outlet 5 and the second water outlet 6 are respectively connected with the condenser 0. Specifically, the first water outlet 5 and the second water outlet 6 may be connected to the condenser 0 in an integrated structure, or may be connected to each other through a pipe.
When water is injected into the water tank 2, since the position of the second water outlet 6 is low, when the water reaches the position of the second water outlet 6, the water flows into the condenser 0 from the second water outlet 6 to realize the cooling function of the condenser 0. When the water level is higher, that is, more water is injected into the water tank 2 to reach the position of the first water outlet 5, water flows into the condenser 0 from the first water outlet 5 to perform a washing function of the condenser 0.
In order to achieve the cooling function of the condenser 0 requiring as little water as possible, a second water outlet 6 may be provided at the bottom of the water tank as shown in fig. 1. In addition, since the flushing function usually requires a much larger water flow than the cooling function, in an embodiment of the invention, the flow cross section of the first water outlet 5 may be made larger than the flow cross section of the second water outlet 6. For example, if circular holes are used for both water outlets, the diameter of the first water outlet 5 may be larger than that of the second water outlet 6, so that the water flow from the second water outlet 6 is smaller and the water flow from the first water outlet 5 is larger, so as to meet the requirements of cooling and flushing, respectively.
Besides, there is also an implementation manner, even if the number of the first water outlets 5 is larger than that of the second water outlets 6, for example, 5 first water outlets 5 are provided, and one second water outlet 6 is provided, so that the water flow flowing into the condenser 0 from the first water outlets 5 is also larger, and the water flow flowing into the condenser 0 from the second water outlets 6 is smaller, thereby respectively satisfying the requirements of cooling and flushing.
Of course, the flow cross section of the first water outlet 5 is larger than the flow cross section of the second water outlet 6, and the number of the first water outlets 5 is larger than the number of the second water outlets 6, which can be adopted simultaneously. The size and number of the flow cross sections of the first water outlet 5 and the second water outlet 6 can be determined according to the actual water demand of the cooling water and the flushing water.
When the cooling function of the condenser 0 needs to be realized, that is, when the cooling function of the condenser 0 is triggered, the water control valve 1 needs to be controlled to be opened with a smaller opening rhythm: the opening time does not exceed V/(m-m1), V is the capacity of the water tank from the position of the first water outlet 5 to the bottom of the water tank 2, m is the flow rate of the water control valve 1, and m1 is the flow rate of the second water outlet 6, so that the water level injected into the water tank 2 does not exceed the first water outlet 5, and the water is prevented from flowing out of the first water outlet 5. The closing time does not exceed the time required for the water in the water tank 2 to run out, so that the flow of the cooling water flowing into the condenser 0 is not cut off, and the cooling water is ensured to be as stable as possible.
When the flushing function of the condenser 0 needs to be realized, that is, when the flushing function of the condenser 0 is triggered, the opening time of the water control valve 1 needs to be controlled to ensure that water flows out of the first water outlet 5, for example, the opening time of the water control valve 1 can exceed V/(m-m1), when water is already in the water tank 2, the water inlet time can be appropriately reduced, and the specific opening time can be determined according to the flushing requirement. Such that water flows out from the first water outlet 5 to generate a large flow of water injected into the condenser 0, thereby implementing a washing function of the condenser 0.
When the water control valve 1 is selected, the selection can be carried out according to the specific volume of the water tank 2, the opening sizes of the first water outlet 5 and the second water outlet 6 and the like, and the recommended range is 2-15L/min.
The cooling function is a relatively important and delicate function for the control of the condenser 0, and the cooling effect is better as the water flow is more smooth. Fig. 2 is a comparison of a set of experimental data, and in fig. 2, line 1 represents the water flow generated by the water control valve of 10L/min through the second water outlet 6 of the water tank 2 in the manner of the present invention. Line 2 represents the water flow generated when the water control valve implementing the cooling function is 0.5L/min, using the prior art approach. Line 3 represents the ideal flow, i.e., a completely stable flow. Therefore, the fluctuation of the cooling water flow generated by adopting the method of the invention is small and is relatively close to the completely stable water flow, and if the standard deviation of the flow is adopted to represent the fluctuation size of the flow, the standard deviation of the cooling water flow generated by adopting the method of the invention is only 20% of the standard deviation of the cooling water flow generated by adopting the method in the prior art, the stability degree is obviously improved, and the effect of the cooling function can be ensured.
Therefore, the mode provided by the invention has the following advantages:
1) only one water control valve is needed to realize the cooling and flushing functions of the condenser.
2) Because the size of the water flow for cooling is controlled by the second water outlet 6 of the water tank, a water control valve with larger flow can be adopted, so that the problem of poorer flow precision caused by a small-flow water control valve can be reduced.
3) The stability of the cooling water flow generated by the mode provided by the invention is obviously improved, so that the effect of a cooling function is ensured.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
