The specific embodiment

Below, with reference to the description of drawings embodiments of the present invention.In addition, the present invention is not limited to this

Embodiment.

(embodiment 1)

With reference to Fig. 1～Fig. 6, the scrubbing-and-drying unit of embodiments of the present invention 1 is described.Fig. 1 is the concise and to the point cutaway view of the scrubbing-and-drying unit of embodiments of the present invention 1.

In Fig. 1, in the scrubbing-and-drying unit of present embodiment, be provided with: the swing roller 2 of taking in clothes 33; Interior bag swing roller 2 is also guaranteed its rotation sink 15 freely; Directly be connected with the rotating shaft 16 of swing roller 2, rotation drives the dry motor 3 of washing of swing roller 2; And have heat pump circulating system 17, guiding is removed the dehumidification portion 18 of moisture effect from the humid air of sink 15 when clothes 33 dry.Heat pump circulating system 17 constitutes by second heat exchanger 20 and the capillary 21 that the refrigerator pipes 17a with the circulation cold-producing medium links compressor 8, first heat exchanger 19 that absorbs heat, heating.And then, have: the air supplying part 23 that the air between first heat exchanger 19, second heat exchanger 20 and the sink 15 is moved via wind path 22 circulations.

In addition, first heat exchanger 19 is drawn into heat the effect in the cold-producing medium from air owing to have by making in the cold-producing medium evaporation of internal circulation, therefore be also referred to as evaporimeter etc., on the other hand, second heat exchanger 20 is owing to have the effect of giving heat from cold-producing medium to air on the contrary, therefore be also sometimes referred to as condenser, especially the cold-producing medium of Shi Yonging is not limited to various fluorine Lyons etc., for example also can be to use carbon dioxide (CO with supercriticality ₂) cold-producing medium etc., in such cases, can certainly be gaseous coolant etc.

And, be connected with first drive circuit 24 of the dry motor 3 of driving washing and second drive circuit 25 of drive compression machine 8.First rectification circuit 26 is a multiplication of voltage shape, and to the DC voltage of the about 250V of first drive circuit, 24 supplies, second rectification circuit 27 also is a multiplication of voltage shape, supplies with the DC voltage of 230V to second drive circuit 25.

And then attaching plug 28 is constructed as follows: suppress power high-order harmonic generation and terminal noise, supply with AC power to first rectification circuit 26 and second rectification circuit 27 simultaneously.In addition, water supply portion 32 by running water pipe 30, and utilize to open and close and feed or the feed water valve 31 that stops from the water of running water pipe 30 constitutes, supply with water from water supply portion 32 to sink 15, sink 15 in, wash clothes 33.

Draining valve 34 is located at the bottom of sink 15, and retaining in sink 15 is down washed or washed in off position, under opening state, and the water in drainpipe 35 discharge sinks 15.

When clothes was dry, the humid air in the sink 15 was sent into first heat exchanger 19 of low temperature by wind path 22, and at this generation dew that is cooled, this dew drips and lodges in the water storage dish 36 that is provided with in the bottom of heat pump circulating system 17.

Draining pump 37 is discharged the dew that accumulates in the water storage dish 36, and it comprises: miniature motor 38, and it is done with direct current 12 couchers, and has not shown permanent magnet, brush, commutator; First gear 39, it is by motor 38 rotations; Second gear 40, itself and first gear 39 are chimeric, and to opposite with first gear 39 towards rotation; Shell 41, it surrounds first gear 39 and second gear 40; With filter 42, it is located at the entrance side of shell 41, and draining pump 37 is drawn dew from water storage dish 36, once presses upside, flows out to and overflows ware 43, is released to the dew that overflows ware 43 and passes through discharger 44 again, interflow in drainpipe 35.

In the present embodiment, as draining pump 37, used to have first gear 39 and second gear 40 it is called as the draining pump of so-called gear pump etc., so if the current then of reversing towards also opposite, can also be removed accumulates in the effect of the foreign matter in the filter 43.

The drive pattern example of this draining pump 37 is described with reference to Fig. 2.Fig. 2 A is illustrated in the situation of driving draining pump 37 under the certain intervals, and Fig. 2 B represents to take at random key element intermittently to drive the situation of draining pump 37, and Fig. 2 C is illustrated in the situation of Continuous Drive draining pump 37 in the drying process of scrubbing-and-drying unit.Herein, shown in Fig. 2 A or Fig. 2 B, discontinuous operation is in order to lighten the load, even so that draining pump 37 cheap and lack the draining pump of endurance quality a little also can be practical.But, shown in Fig. 2 C, even if draining pump 37 is worked all the time, in the use also completely without problem.In addition, because when when washing or dehydration, the part of the washings that leak via wind path 22 from sink 15 might accumulate in the water storage dish 36, so can further avoid this unfavorable condition of spilling water if also continue to drive 37 of draining pumps this moment, is preferred in this.

Then, the water level of the dew in the water storage dish 36 that accumulates in heat pump circulating system 17 detects in water level detecting portion 45, and possesses first thermistor 46 that has the spontaneous heating characteristic.During in prescribed limit, stopping the work of dehumidification portion 18 from the signal of first thermistor 46.In other words this state mean, when draining pump 37 breaks down because of the problems such as obstruction of foreign matter, has the supply of dew is stopped, and prevents this important role of spilling water of water storage dish 36.

Therefore, owing to then can not discharge dew if contingency draining pump 37 breaks down, so dew continues to accumulate in the water storage dish 36.At this moment, arrived the water level of stipulating, then stopped the work of dehumidification portion 18 as if the water level that detects dew by water level detecting portion 45.Therefore, do not cause the further rising of dew water level, thus can prevent reliably because of water level excessive rising, enter secondary failure that the water in the component parts of scrubbing-and-drying unit inside causes, delay work and water overflowing outside scrubbing-and-drying unit etc.

In the present embodiment, and first thermistor 46 position of detecting the air themperature between first heat exchanger 19 and second heat exchanger 20 side by side be provided with the temperature detecting part 48 that constitutes by second thermistor 47.And then, when temperature detecting part 48 is set to the water level rising of the dew in accumulating in water storage dish 36, can together connect with first thermistor 46 with water, also detect the height of the temperature of water.

Fig. 3 is the amplification view that has the water level detecting portion 45 of first thermistor 46 and have the temperature detecting part 48 of second thermistor 47.In Fig. 3, first thermistor 46 has by the pipe 49 of polytetrafluoroethylene (PTFE) (registration mark) system around and fills the insulating barrier 51 that material 50 constitutes, the external diameter of the pipe 49 of described polytetrafluoroethylene (PTFE) system is 3mm and is imbued with insulating properties and heat resistance, described filling material 50 is by constituting from managing the heat stable resin that 49 two ends up and down injects, the terminal 52,53 of first thermistor 46 is drawn from having insulation-coated lead 54, but even terminal 52,53 constitute also can guarantee when being submerged in state in the water becoming that water level rises and water between electric insulation.

And then, in the present embodiment, in the windproof body 55 of first thermistor 46 that covers with insulating barrier 51 and then the tube shape that is accommodated in both ends open.This windproof body 55 is made of the pipe of resinous diameter 9mm.So, because the windproof body 55 of tube shape is arranged in the arranged outside of insulating barrier 51, so it is low and be under the situation of hollow at water level, windproof body 55 has and weakens the effect that collides the air flow on first thermistor 46, distributing of heat during 46 spontaneous heatings of first thermistor reduces thus, the temperature of first thermistor 46 is higher, can reach about 140 degree Celsius.On the other hand, under the situation about not had by water logging in the water level rising, water is invaded from the peristome of the downside of insulating barrier 51, and the water levels in the windproof body 55 rise, and air can freely be discharged from the peristome of upside.

Therefore, when the position that water level rises to first thermistor 46 is L1, it is compared when low with water table ratio, can further increase poor from the mode of distributing of the heat of first thermistor 46, can set the boundary that the flase drop of the water level that relative noise etc. causes is surveyed biglyyer.The mode of distributing from the heat of first thermistor 46 when rising because of the diameter of windproof body 55 or the windproof performance of material or water level changes, but in the present embodiment, the windproof body 55 of the tube shape by adopting diameter 9mm can access good water level detecting characteristic.

Especially, in the scrubbing-and-drying unit that has used heat pump circulating system 17, for example be set at higher value about per minute 2m3 by air quantity with air supplying part 23, can access and utilize warm wind-warm syndrome degree is can adopt cold-producing medium such as fluorine Lyons and about 70 degree Celsius realized and the low-down air of humidity, clothes 33 when sending in the sink 15 carries out dry well dried effect, can access also less excellent drying properties such as fold.

Therefore, influence this formation when more effectively being reduced in the wind that produces because of air supplying part 23 and colliding first thermistor 46, bring into play extremely important function with spontaneous heating characteristic by windproof body 55.

In addition because the upper and lower end parts of windproof body 55 is open, so if water level rises, becoming the open end of water by the downside of windproof body 55, and insulating barrier 51 between have the state of water.Therefore, when water arrives the height (L1) of first thermistor 46, the heat that spontaneous heating produced of first thermistor 46 is crossed insulating barrier 51 and is dispersed in the water, first thermistor 46 is cooled, so the temperature of first thermistor 46 reduces, can carry out the detection of water thus, promptly detect the water level of regulation.

In the present embodiment, be provided with the temperature detecting part 48 that has adopted second thermistor 47 with the roughly the same height L1 of first thermistor 46, cover with resinous insulating barrier 59 around second thermistor 47, with the terminal 57,58 guaranteeing to draw from the lead 56 that tape insulation is covered and the electric insulation between the water on every side.

In addition, in the present embodiment, owing to used second thermistor 47 with the current value that almost can ignore the degree of spontaneous heating, so insulating barrier 59 does not need to use the extra high resin material of heat resistance.

Then, Fig. 4 represents the circuit diagram of testing circuit 81.Testing circuit 81 is connected with first thermistor 46, and second thermistor 47 of temperature detecting part 48 of water level detecting portion 45.First thermistor 46 via connector 82 and 250 ohm resistance 83, and the transistor 84 of NPN shape be connected.

The terminal of the upside of resistance 83 is connected with the dc source of 12V 85, output Q by microcomputer 86 is high, and under the state that transistor 84 is opened, electric current is supplied in first thermistor 46 from resistance 83, thereby make first thermistor 46 cause sufficient spontaneous heating.

In addition, in the present embodiment, diode 87 also is set, and this diode 87 is used to the output Q that prevents at microcomputer 86 for low when having closed transistor 84, because of the inductance in the wiring that has first thermistor 46 etc. produces overvoltage and between the collector emitter of transistor 84.Resistance 88 and capacitor 89 play a role as filtering circuit in order to remove noise contribution from the voltage of first thermistor 46, thereby obtain muting aanalogvoltage V1.

Comparator 90,91,92,93,94 is aanalogvoltage V1 and threshold voltage separately relatively, to the high and low signal of microcomputer 86 outputs.Voltage source 95,96,97 is imported the voltage of 6V, 5V, 4.5V and it is compared to comparator 90,91,92 respectively.

In addition, resistance 98,99,100 is with dc source 85 dividing potential drops of 12V, to the branch voltage power of comparator 93,94 input 11V and 1V.The dc source 101 of 5V is as the power supply of microcomputer 86 grades and work.The lead-out terminal of the open collector of comparator 90,91,92 (open collector) is connected with dc source 101 by resistance 102,103,104 respectively, and is connected with input terminal D1, D2, the D3 of microcomputer 86.

The open collector lead-out terminal that has connected comparator 93,94 each other after, be connected with the dc source 101 of 5V by resistance 105, with the E terminal of so-called " Y " " or " signal input microcomputer 86.

With regard to second thermistor 47, via connector 106, be connected with the dc source 101 of 5V by 3.92 kilohms resistance 107, as value of current flowing in second thermistor 47, much smaller than first thermistor 46, thereby, spontaneous heating be about 1mW than low value, use with the degree that the temperature that almost can ignore second thermistor 47 that spontaneous heating produced rises.

With regard to the voltage of second thermistor 47, the filtering circuit that forms by resistance 108 and capacitor 109 through the aanalogvoltage V2 that is used to obtain the noiseless influence, A terminal with microcomputer 86 reads in analog voltage, inner transformation at microcomputer 86 becomes digital value, and then inner program carries out work, is transformed into temperature data thus.

Fig. 5 is the curve map of the operating characteristic of expression water level detecting portion 81, and the longitudinal axis is aanalogvoltage V1, and transverse axis is a temperature, the temperature detection value that this temperature has been equivalent to adopt the temperature detecting part 48 of second thermistor 47 to be detected.

Thin dotted line O represents the positive input terminal voltage of comparator 93, thin dotted line S represents the sub-voltage of negative input end of comparator 94, temperature during stable in the time of when W shown in the solid line and A represent respectively that first thermistor 46 is in air and in water and the relation of aanalogvoltage V1.

In addition, stair-stepping thick dashed line is the threshold value of relative V1, in the present embodiment, is 20 degree Celsius when following in the detected temperatures of temperature detecting part 48, and the voltage 6V of voltage source 95 is effectively, and microcomputer carries out the judgement of water and air by importing D1.In the detected temperatures of temperature detecting part 48 are 40 degree Celsius when above, and the voltage 4.5V of voltage source 97 is effectively, and microcomputer carries out the judgement of water and air by input D3.When the detected temperatures of temperature detecting part 48 at 20 degree Celsius during to the scope of 40 degree, the voltage 5V of dc source 96 is effectively, microcomputer carries out the judgement of water and air by input D2.

Under arbitrary temperature conditions, when V1 is higher than threshold value, be judged as corresponding and become effective terminal step-down with the temperature separately in D1 to D3, first thermistor 46 is immersed in the water, be the position that water level rises to first thermistor 46, thereby the running of the compressor 8 of dehumidification portion 18 is stopped.

Therefore, when during in (more than the threshold value) prescribed limit, the work of dehumidification portion 18 being stopped from the signal of first thermistor 46.And, in the present embodiment, owing to make output as mentioned above by temperature detecting part 48, judge from the signal V1 of first thermistor 46 whether in the threshold value of prescribed limit, change in these 3 grades of 6V, 5V, 4.5V, so can from Celsius 0 spend to 50 the degree temperature ranges in, correctly carry out the judgement of water and air, whether arrived first thermistor 46 thereby can understand water level accurately.

In addition, as shown in Figure 3,, second thermistor 47 of first thermistor 46 and temperature detecting part 48 is roughly the same height L1 because being set up in parallel, thus when rising, water level roughly immerses in the water simultaneously, thus can carry out correct judgement.

But, under situation about being provided with the state that has difference in height a little, the both sides that rise to first thermistor 46 and temperature detecting part 48 at water level are dipped into the stage in the water at least, also can detect liter waterborne.And, surpass under the situation of the threshold value 11V that represents by thin dotted line O at signal V1 from first thermistor 46, be as common from first thermistor 46 signal value and the value that can not have, can think the broken string of the element that caused first thermistor 46 itself, or produce and do not insert the unusual of connector 82 etc.

In addition, at the signal V1 from first thermistor 46 is that the threshold value 1V shown in the thin dotted line S is when following, also be as common from first thermistor 46 signal value and the value that can not have might produce fault and become short-circuit condition by thermistor element.In the present embodiment, when so high and when lower, all be judged to be first thermistor 46 beyond normal range (NR), thereby stop the work of dehumidification portion 18 than S than O.

Therefore, no matter can under the state of the fault of placing first thermistor 46, not use, can be with anti-possible troubles that terminates in such as 2 times later faults, electric leakage, electric shocks.

In the present embodiment, because the output common land of comparator 93,94 connects, so when higher than O and under the arbitrary situation when lower than S, the R terminal of microcomputer 86 is step-down all, being judged to be is the unusual of first thermistor 46, thereby stops dehumidification portion 18.When wanting to distinguish broken string or short circuit, by with reference to from any of D1 to D3, just can distinguish, for example when D1 is low, can be judged as be broken string unusually, when D1 was high, decidable was for being that short circuit is unusual.

As mentioned above, in the present embodiment, detection output corresponding to temperature detecting part 48, adopt the scope in 3 stages, to by input part dc source 95,96,97 be set with corresponding threshold separately at comparator 90,91,92, and be embodied as the stage shape of 6V, 5V, 4.5V, but be not particularly limited in so constituting.For example, also can adopt the port of the aanalogvoltage that can import microcomputer 86, read in the voltage corresponding with V1 as aanalogvoltage, by the program in the microcomputer 86, the threshold ratio of the numeral corresponding with synthermal test section 48.

In such cases, for example, the curve setting threshold value shown in also can the double dot dash line T of enough Fig. 5, the compound mode by program also can realize quite level and smooth curve, so also can make the spacious and comfortable degree of relative noise etc. fully big in whole temperature range, also can make stability higher.

In the present embodiment, detection output corresponding to temperature detecting part 48 makes changes of threshold, but for example also can be to the output of first thermistor 46, by the output signal that obtains from temperature detecting part 48, carrying out calculating such as addition subtraction multiplication and division implements to revise, the magnitude relationship of the threshold value of more revised value and regulation, thus judge whether water level has reached first thermistor 46.In a word, even as from the output of first thermistor 46 with from the function of two outputs of the output of temperature detecting part 48, the method whether the output water level arrives also has equal effect, belongs to category of the present invention.

In addition, in the present embodiment, except that first thermistor 46 with spontaneous heating, temperature detecting part 48 also is set, detect the environment temperature of first thermistor 46, but also can switch the size of the spontaneous heating of first thermistor 46 by making the size variation of the electric current that in first thermistor 46, flows.In such cases, also can form degree that the temperature that can ignore first thermistor 46 that spontaneous heating produces rises during, detect environment temperature, determine threshold value by its value, compare with analog voltage under the state with spontaneous heating.

In addition, in the present embodiment, because as water level detecting portion, the moving part that does not also have normally used in the past floating drum mechanisms such as (float), so it is also excellent aspect reliability, especially under the situation of scrubbing-and-drying unit, sometimes also when waiting, dehydration produces sizable vibration, even but under the condition that so vibration is arranged, also can carry out suitable water level detecting work, and under the situation that has applied vibration, owing to can also prevent the noise that the play because of the moving part of machinery produces, so also have the effect that can form quiet scrubbing-and-drying unit.

In addition, in the present embodiment, originally detect dew in the drying and accumulate in situation in the water storage dish 36, drive draining pump 37, water storage is discharged to the outside, prevent spilling water, also monitor water level detecting portion 45 all the time but be in the suds, at the bubble that splashes water or form because of the foaming of washing agent that produces because of flowing of the fierceness of the water of the rotating torques of following infrequent swing roller 2, splash to wind path 22 from sink 15, flow in the water storage dish 36 and when accumulating by wind path, also drive draining pump 3 water is discharged to the outside, thereby stop spilling water.

Describe its work in detail with reference to Fig. 6.In Fig. 6, the longitudinal axis represents to wash dry stroke (a), the duty (b) of water level detecting portion 45, the water level (c) of water storage dish 36, the operating state (d) of draining pump 37 respectively.Transverse axis is the time.

At first, have shown in (a) from washing the stroke of drying.Even also as (b) shown in, carry out the supervision of the water level of the interior water storage of water storage dish 36 by water level detecting portion 45 in the stroke of the present invention herein beyond the drying.

According to described reason, in washing (also comprising flushing), shown in (c), the water level of water storage dish 36 rises as water level 121 because of washings or the bubble that flows into by wind path 22.If reach the spilling water threshold value 122 of water level detecting portion 45, then shown in draining pump work 123, draining pump 37 is open-minded, during work is certain, and shown in water level 121, the decline of water table of water storage dish 36.Therefore, even the water that passed through wind path 22 of being in the suds, bubble enter, water storage dish 36 is spilling water not also, thereby the reliability of spilling water improves relatively.

In addition, when drying process, shown in water level 124, dew accumulates in the water storage dish 36, and water level rises, if reach the level of threshold value 122, then shown in draining pump work 125, draining pump 37 drives, and carries out draining, thereby the water level of water storage dish 36 reduces.

In addition, as the mechanism that has or not of detecting water, following structure was also arranged in the past, 2 electrodes and instrumentation resistance value therebetween promptly are set, in low, be judged as water is arranged between electrode, but especially in scrubbing-and-drying unit, the water that from dehumidification portion 18, comes out, sometimes also become resistance and distilled water with contour water, thereby be difficult to correctly judge having/not having of water, but according to present embodiment owing to adopt first thermistor 46 with spontaneous heating, therefore can with also comprise the washings that overflow from sink 15, correct judgement water has or not under the situation that the resistance value of the water that need detect has nothing to do.

In addition, can be used in insulating barrier 51 these simple formations are set on first thermistor 46, easily constitute electric insulation with terminal 52,53, for example, come instrumentation between electrode, to have this formation of situation of water to compare with the variation that utilizes resistance value in the past, can easily realize safe formation.Especially as the many scrubbing-and-drying units with wetting hand direct control of user, effect is bigger.

In addition, in the above-described embodiment, horizontal arrangement the rotating shaft 16 of swing roller 2, but also not necessarily be defined in horizontal arrangement, it for example also can be the formation that has with the vertical axis that is commonly called vertical shape swing roller of rotation when dewatering, or also can be 20～30 degree and tilt rotating shaft 16 is set with level, so that carrying out the dress of clothes 33 in swing roller 2 easily gets, and then also can be in swing roller 2 further inscapes such as other mechanical part such as additional instance such as oscillator so that when washing, can more effectively wash.

As mentioned above, the scrubbing-and-drying unit of present embodiment, so can provide a kind of with the formation of cheapness will be that high water level and the rotary drum rotating water that splashes is accumulated in the water storage dish by wind path and overflows or washing agent too foams and is accumulated in the water storage dish by wind path equally and overflows because of water level, thereby spill into the anti-possible trouble, the scrubbing-and-drying unit that reliability is high of terminating in of these unfavorable conditions of ground that body is outer and flood user's dwelling house.

(embodiment 2)

Fig. 7 is the time diagram of duty at each position of the scrubbing-and-drying unit of expression second embodiment of the present invention.In addition,, mark identical symbol, omit its explanation the part identical with the scrubbing-and-drying unit of above-mentioned embodiment 1.

In Fig. 7, when the washing of swing roller 2 rotation, water spreads in the sink 15 everywhere.Therefore, the part of washings might enter in the water storage dish 36 by wind path 22.Especially more the user has and wants to inject the custom that abundant water washs.In such cases, the part of washings enters the possibility height in the wind path 22.

In addition, the custom of putting into washing agent is too much arranged also, at this moment, it is comparatively violent to foam, thereby the possibility that enters in the wind path 22 is high equally.In such cases, shown in water level 126, when washing and flushing, the water level of water storage dish 36 might considerably rise.Sometimes also might overflow.Therefore,, enter dry trip, then have dew further to be accumulated in the water storage dish 36 if the dehydration stroke finishes, thereby because of overflowing the danger that causes the outer spilling water of machine.

In the present embodiment, after entering dry trip, immediately shown in draining pump work 127, make draining pump 37 work forcibly, discharge the time lodges in water storage in the water storage dish 36 in washing, and the anti-high scrubbing-and-drying unit of reliability that terminates in possible trouble, do not produce the outer spilling water of machine that overflows that a kind of dew will be because of drying the time causes can be provided thus.
