Main technical schemes of the present utility model is, utilize the conductive characteristic of water, two bonding jumpers are set in the water box of tumble drier, behind two bonding jumpers of the condensed water submergence of collecting in the water box, just can detect two resistance variations between the bonding jumper, can judge the water level height according to this resistance variations, and control the draining pump action in view of the above.
Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Embodiment one
Fig. 1 is the structural representation of the utility model tumble drier water level switch embodiment, and as shown in Figure 1, the water level switch of present embodiment can comprise first bonding jumper 11, second bonding jumper 12, and is positioned at detecting unit 13 and control module 14 on the controller.
Wherein, first bonding jumper 11 and second bonding jumper 12 can be fixed on the inwall of bottom water box, for example, can be fixed on its two opposite inner walls.Extend in the bottom water box, and these two bonding jumpers are to expose in the water box, can directly contact with the condensed water collected in the water box.In concrete enforcement, can on the inwall of bottom water box, slot, two above-mentioned bonding jumpers are inserted in this groove and can fix.First bonding jumper 11 and second bonding jumper 12 are connected with positive and negative electrode in the detecting unit 13 respectively, in addition, comprise power supply in the detecting unit 13, this power supply can be the safety extra low voltage (SELV) power supply, when these two bonding jumpers of condensed water submergence, detecting unit 13, first bonding jumper 11, condensed water and second bonding jumper 12 can form conductive path.Detecting unit 13 can detect the resistance variations that obtains between first bonding jumper 11 and second bonding jumper 12, and this resistance value is transferred to connected control module 14, is moved according to this resistance value control draining pump 15 by control module 14.
The operation principle of the water level switch of present embodiment is by the fixed position of proper metal bar is set, just can reach the purpose of measuring water level by measuring between two resistances judgement bonding jumpers between the bonding jumper whether water is arranged.Specify as follows:
Between first bonding jumper 11 and second bonding jumper 12, there is not condensed water, be that water level in the bottom water box is when low, condensed water can not touch first bonding jumper 11 and second bonding jumper 12, it is very big that detecting unit 13 can detect the resistance value R1 that obtains between these two bonding jumpers, is approximately the Ω greater than 100M.Control module 14 just can judge that according to this resistance value R1 the water table ratio that obtains in the bottom water box is lower, then controls draining pump 15 and is failure to actuate, and does not carry out draining this moment.
Between first bonding jumper 11 and second bonding jumper 12, there is condensed water, it is the water level rising in the bottom water box, and during these two bonding jumpers of submergence, because metal has good electrical conductivity, condensed water also can conduct electricity, therefore, the above-mentioned circuit turn-on that comprises these two bonding jumpers, condensed water and detecting unit 13.At this moment, detecting unit 13 can detect resistance R 2 resistances that obtain between first bonding jumper 11 and second bonding jumper 12 to be reduced greatly, is approximately tens kilo-ohms.At this moment, control module 14 can judge that the water level that obtains in the bottom water box has risen to certain height according to this resistance value, should carry out draining, then control draining pump 15 and start working, the condensed water in the bottom water box is discharged in the water storage case at top by drainpipe 16.
For example, when detecting resistance between first bonding jumper 11 and second bonding jumper 12 greater than setting value when (2 megaohm), the water level in the expression bottom water box reaches preset value, and then control module 14 can be exported " 1 " signal, and the control draining pump begins draining; When detecting resistance between first bonding jumper 11 and second bonding jumper 12 less than setting value when (2 megaohm), water level in the expression bottom water box does not reach preset value as yet, then output " 0 signal ", the control draining pump stops action, thereby plays the effect of a similar water bit switch.
In above-mentioned testing process, because condensed water approaches pure water, resistance is more stable, and therefore, to detect the resistance value that obtains also more stable for detecting unit 13 behind two bonding jumper fixed positions, and promptly after two bonding jumpers were fixing, discharge level was also just fixed.In addition, can be by adjusting the resistance value of distance adjustment between it between two bonding jumpers; Perhaps in the position that is provided with of bottom water box predetermined discharge level is set by adjusting two bonding jumpers.
Further, first bonding jumper 11 and second bonding jumper 12 can be set to a long weak point, and promptly its position that extend into described bottom water box lays respectively at different horizontal lines.For example, second bonding jumper 12 can extend into the bottom of water box, and first bonding jumper 11 can only extend into the middle and upper part of water box.The reliability that can flood and detect is set like this.Its principle is specially, consider that dryer has vibrations in running, fluctuation also may appear in the liquid level in the bottom water box thereupon, if adopt the bonding jumper of two length unanimities, liquid level has reached the requirement water level still because liquid fluctuating causes another root bonding jumper to contact, so just may cause spilling water, unsettled contact the signal flase drop may occur and survey; And after adopting inconsistent two bonding jumpers of length, long bonding jumper i.e. first bonding jumper 11 can be immersed in the water always, be convenient to detect reading, when the short bonding jumper of liquid level contact is second bonding jumper 12, detect its change in resistance arrival setting and just can move immediately, thereby can improve accuracy of detection.
The tumble drier water level switch of present embodiment by fixing two bonding jumpers on the inwall of bottom water box, can be judged the water level height by the resistance variations that detects between two bonding jumpers, and sensed water level and carry out draining is saved the energy in time; And simple in structure, cost is low.
