Description
The present invention relates to a kind of dehumidifier, particularly relate to a kind of have detect evaporimeter frost, and for the dehumidifier of the survey ice sensor that defrosts.
This dehumidifier up to now has been disclosed on the public strictly according to the facts clear 58-50183 communique, the receiving vessel of compressor and dehumidifying water is set below dehumidifier is intrinsic, constitute the freeze cycle that comprises above-mentioned compressor up, evaporimeter with the performance dehumidification function, condenser and pressure fan are configured to row, by the room air of evaporator cools pressure fan from the air suction inlet suction, after making the moisture dewfall and dehumidifying in the room air, utilize the cold air behind the heat release heating and dehumidification of condenser, blow to indoor from blow-off outlet being heated to indoor temperature dehumidified air after drying.
In such dehumidifier, when turning round under low temperature environment, because the temperature of evaporimeter is lower than 0 ° Celsius, the water after the dehumidifying frosting build-ups ice on evaporimeter.After ice was formed a certain amount of ice, when being covered by the thick ice of one deck on quite a few of evaporimeter, the heat exchanger effectiveness of evaporimeter just descended, thereby dehumidification function also descends.Therefore, at this moment, utilize the survey ice sensor that detects the icing situation of evaporimeter, temporarily stop compressor operation, during stall, defrost near the Defrost heater energising that is configured in the evaporimeter, after defrosting finishes, make compressor start running again, by this way to the dehumidifier control of turning round.
This survey ice sensor, at present by having bellows (ベ ロ-ス) constitute with the body of contact and the capillary of the tubule structure that is connected with this bellows, utilize the higher action gas gas heat originally of the coefficient of expansion of enclosing bellows and capillary inside, its body is arranged in the electric component container cavity on the top in the dehumidifier, in addition, capillary leading section (hereinafter referred to as temperature measuring head) is installed in the evaporimeter front from its body uses with extending.
When the temperature measuring head of surveying ice sensor is higher than the temperature of body,, pressure inside makes contact because of rising.Therefore, exist the working condition of contact to be subjected to the body Temperature Influence, the action of contact varies with temperature and problem of unstable.Particularly temperature measuring head detects ice on the evaporimeter, Defrost heater is switched on, when defrosting running, though evaporimeter does not eliminate frost fully, near the ice the temperature measuring head dissolves on a small quantity, when evaporimeter exposes some slightly, compressor is subjected to the influence of Defrost heater heat, can start running in advance, cause control unstable, reliability reduces.
In existing dehumidifier can not be highly stable because survey the installation of ice sensor, so during use, the position of temperature measuring head can change, also just can not correctly detect evaporimeter white situation.
In existing dehumidifier, survey the on/off of contact of ice sensor and evaporimeter white situation needn't be consistent, for compressor and defrosting heater are carried out on, use microcomputer and defrost clock, for after surveying the ice sensor reaction, at the appointed time, on/off compressor or Defrost heater just must have expensive electric component, in addition, because of the circuit layout assembling becomes more complicated, cause the goods price to rise.
In view of the above problems, the purpose of this invention is to provide a kind of the loading can install the temperature measuring head of surveying ice sensor really and suitably, in conjunction with evaporimeter white situation reliably control the dehumidifier of compressor, Defrost heater on/off and running control circuit simple in structure.
Compressor and pressure fan are housed in the body housing of dehumidifier of the present invention, on shell, form the suction inlet and the outlet of room air, make the room air that sucks by above-mentioned pressure fan flow through evaporimeter and condenser in the air channel that is configured in successively between above-mentioned suction inlet and the outlet, by evaporimeter air is cooled off and dehumidifying, by condenser it is heated again, air after the dehumidifying is arranged to indoor, by survey ice sensor detect on the evaporimeter white situation, stop to make cold-producing medium to be circulated throughout the compressor operation of above-mentioned evaporimeter and condenser, connect defrosting heater, evaporimeter is defrosted, detect the defrosting situation of evaporimeter, disconnect above-mentioned Defrost heater, make the above-mentioned compressor running running that dehumidifies, it is characterized in that surveying ice sensor is made of the capillary of the body with bellows and gauge tap with the tubule structure that is connected with this bellows, at above-mentioned bellows and the inner working gas of enclosing of capillary, above-mentioned body is arranged in the electric component container cavity that is formed at the top in the dehumidifier, the temperature measuring head of above-mentioned capillary leading section is installed near the above-mentioned evaporimeter, detect the generation state of the frost that adheres on the above-mentioned evaporimeter by above-mentioned temperature measuring head, utilize gas thermal sensitivity to make above-mentioned gauge tap on/off, near the heater of energising when the bellows of above-mentioned body, setting simultaneously defrosting.
In the case, by between power line, be connected in series by above-mentioned compressor and fan electromotor be connected in parallel and compressor drive circuit and by above-mentioned Defrost heater, above-mentioned gauge tap and above-mentioned heater be connected in parallel and the Defrost heater circuit, when the dehumidifying running, connect gauge tap, with above-mentioned Defrost heater short circuit, make compressor and fan motor runs, and when the defrosting running, disconnect above-mentioned gauge tap, connect above-mentioned Defrost heater and above-mentioned heater.
Like this, owing to detect when freezing on the evaporimeter changing the survey ice sensor detect by the pressure that utilizes internal work gas, disconnect the short circuit gauge tap of Defrost heater, by compressor and fan electromotor Defrost heater is switched on, therefore can switch to the defrosting running from the dehumidifying running truly feasiblely, simultaneously, make the condition of the good detection performance that obtains surveying ice sensor, near the maintenance of bellows that is sensor body portion is more more stable than the temperature measuring head of its other end, then can guarantee to detect when defrosting finishes action reliably.
At this moment, preferably set the resistance of above-mentioned compressor inside and the resistance of above-mentioned Defrost heater so respectively, make that the voltage drop between above-mentioned compressor was littler than the voltage drop between above-mentioned Defrost heater, and will be lower than driven compressor voltage when above-mentioned gauge tap disconnected defrosting.
Therefore, because break-make by the gauge tap of surveying the ice sensor manipulation, make the Defrost heater that short circuit and compressor are connected in series when running well, and make compressor operation, with detecting when freezing, remove short circuit, to the Defrost heater energising, to the Defrost heater control of switching on, in addition, the resistance value of the resistance value ratio piston compressor of setting Defrost heater is much bigger, so that when running well, provides necessary driving voltage to compressor, and provide the voltage that is lower than below the driving voltage automatically in when running defrosting, can make compressor operation or stop, having saved existing being exclusively used in and made compressor stop the switch driven element, simplify circuit structure, reduced cost, and different with mechanical switch, misoperation can not appear, can access very high reliability to control.
The structure of dehumidifier of the present invention is: be provided for above-mentioned capillary leading section is fixedly remained on carrier on the refrigerant piping of above-mentioned evaporimeter, this carrier is by the carrier body of axle shape, be arranged on the axle direction of rotation of above-mentioned carrier body and intersect 180 degree, keep locational a plurality of carrying tablets of predetermined distance along the direction of principal axis of above-mentioned carrier body, be arranged on being used on the same direction leading section of above-mentioned carrier clamp above-mentioned evaporimeter pipe arrangement the pipe arrangement clamping part and be arranged on the opposite side of above-mentioned same direction leading section of above-mentioned carrying tablet, be used to keep the capillary maintaining part capillaceous at above-mentioned temperature measuring head place.

Below, with reference to the description of drawings embodiments of the invention.
Shown in Fig. 1,2 and 3, the machine body top of the dehumidifier of present embodiment is covered by the shell 3 that protecgulum 1 and bonnet 2 combine.Form the suction inlet 4 that sucks room air in the front upper of its protecgulum 1, at its lower right side opening that water receptacle 5 comes in and goes out that is formed for dehumidifying.Setting operation plate 6 on protecgulum 1 disposes the display led that starts, stops the switch SW of body and show its running status on this operation panel 6.In addition, on protecgulum 1, have the inclined plane of rising in the middle of the fore-and-aft direction of front upper limb above body housing 3 and also therebetween the position form half 7A of handle.
Inside at the body housing 3 that constitutes by protecgulum 1 and bonnet 2, in the air channel 23 of UNICOM's suction inlet 4 and outlet 8, dispose evaporimeter 10, condenser 11, fan electromotor 12 and pressure fan 13 successively, avoid dehumidifying the position of following left side of face of water receptacle 5 in the bottom on configuration compressor 14.Secondly, as shown in Figure 2, the inboard somewhere of operation panel 6 forms electric component container cavity 24 at an upper portion thereof, holds the bellows 19 of control substrate and survey ice sensor body described later etc. at these 24 middle parts, chamber on protecgulum 1.
When switch SW on the operation panel 6 being connected with such formation, dehumidifier is with regard to entry into service, formed the cold-producing medium circulating path that under driven compressor, makes cold-producing medium just return compressor 14, in evaporimeter 10, absorbed heat, in condenser 11, emitted heat through evaporimeter 10, condenser 11.Simultaneously, because of driving pressure fan 12, indoor humid air flows into body interior from suction inlet 4 shown in Fig. 1 arrow, filter dust by illustrated air cleaner after, during by evaporimeter 10, be cooled and obtain effect on moisture extraction.Cold air after the dehumidifying is by condenser 11 heating, be heated to indoor temperature after, in outlet 8 return chamber.Water after the dehumidifying flows in the dehumidifying water receptacle 5 by guide groove 15.
Yet when such dehumidifier turned round under low temperature environment, dehumidifying water was lower than in temperature on 0 ° the evaporimeter 10 and build-ups ice, and when being covered by ice on the refrigerant piping 16 of evaporimeter 10, heat exchange performance descends, and causes dehumidifying effect to descend.
Therefore, near evaporimeter 10, be provided with and survey ice sensor 17, when becoming this state, can detect temperature decline because of adhering to ice survey ice sensor 17, the control compressor shuts down it, simultaneously, connect Defrost heater (with reference to Fig. 4), dissolve accompanying ice.
Shown in the pie graph of Fig. 4, survey ice sensor 17 is made of the capillary 20 of body and capillary pipe structure, and body has bellows 19 and the switch 25 that is formed by elastomeric material, and capillary 25 is communicated with this bellows 19.Enclosed the high working gas of the coefficient of expansion in bellows 19 and capillary 25, when the temperature of the temperature measuring head capillaceous 18 that extends from body was higher than body, internal pressure rose, and travelling contact 21 contacts with fixed contact 22, and switch 25 is connected.On body, set the heater of energising when defrosting described later near bellows 19.
The body of surveying ice sensor 17 is arranged in the container cavity 24 of the electric component on the interior top of dehumidifier, on the other hand, utilization is at the carrier 26 of the body shown in Figure 5 of establishing a plurality of carrying tablets 27 up and down alternately of the bar-shaped carrying fulcrum 30 that is formed by resin, and the temperature measuring head 18 of capillary 20 leading sections that will extend from its body laterally is installed in the front of evaporimeter 10 as shown in Figure 3.
Fig. 6 is that B from Fig. 5 is to the front elevation of seeing carrier 26.Carrying fulcrum 30 is a shape, is made by such material, and promptly this material has on the direction of rotation of axle to produce when afterburning and reverses, in case remove the elasticity of this power with regard to resilient.On such axle shape carrying fulcrum 30, a plurality of carrying tablets 27 are installed.When these carrying tablets are installed, at first, the carrying tablet 27a of upside is installed on the carrying fulcrum 30.Secondly, downside carrying tablet 27b is positioned at respect to the upside carrying tablet 27a that installs to turn on the position of 180 degree to the axle direction of rotation of carrying fulcrum 30, along axially installing with the interval of regulation of carrying fulcrum 30.Below similarly, upside carrying tablet 27a and downside carrying tablet 27b are positioned on the position of the axle direction of rotation Rotate 180 degree that carries fulcrum 30 alternately, and, are arranged on the position h that keeps predetermined distance along the direction of principal axis that carries fulcrum 30.And, upside carrying tablet 27a each other with downside carrying levy 27b each other be spaced apart 2h.
Fig. 7 shows the sectional view of the D-D line of Fig. 6.Be provided for clamping the pipe arrangement clamping part 28 of the refrigerant piping 16 of evaporimeter 10 on the unidirectional leading section of the carrying tablet 27 of upside carrying tablet 27a and downside carrying tablet 27b.In addition, its back side, promptly the couple positioned opposite of the same direction leading section of carrying tablet 27 is used to remain on the capillary maintaining part 29 of the capillary 20 at temperature measuring head place.The refrigerant piping 16 of evaporimeter 10 is held portion 28 and is clamped by the pipe arrangement on the same direction leading section of a plurality of carrying tablets 27 is flat, and the capillary 20 at the temperature measuring head place of evaporimeter 10 is clamped by the capillary maintaining part 29 that is positioned at its back side.
Fig. 8 utilizes carrier 26 that capillary 20 is installed in key diagram on the refrigerant piping 16.State before the refrigerant piping 16 that Fig. 8 (a) shows the capillary 20 at temperature measuring head place of evaporimeter 10 and evaporimeter 10 is installed on the carrier 26.Under this state, the openings of sizes of capillary maintaining part 29 is r1, and the openings of sizes of pipe arrangement clamping part 28 that is used to clamp the refrigerant piping 16 of evaporimeter 10 is s1.
On the other hand, the state after Fig. 8 (b) refrigerant piping 16 of showing the capillary 20 at temperature measuring head place of evaporimeter 10 and evaporimeter 10 is installed on the carrier 26.The tube grip portion 29 that capillary 20 is formed by upside carrying tablet 27a and downside carrying tablet 27b clamps, and the refrigerant piping 16 of evaporimeter 10 is maintained by pipe arrangement clamping part 28.Under this state, because carrying tablet 27 is to be installed in alternately on the carrying fulcrum 30, so reverse in the axial region generation of carrying fulcrum 30, carrying tablet 27 is that rotate at the center with this axial region.Therefore, the openings of sizes of capillary maintaining part 29 is that (r2＜r1), the openings of sizes of pipe arrangement clamping part 28 that is used to clamp the refrigerant piping 16 of evaporimeter 10 is s2 (s2＜s1) to r2.And carrying tablet 27 reciprocally clamps the refrigerant piping 16 and the capillary 20 of evaporimeter 10.
Promptly when both are installed on the carrier 26 the refrigerant piping 16 of capillary 20 and evaporimeter 10, on the axle of the carrying fulcrum 30 of 27 of adjacent carrying tablets, produce reversing of axle direction of rotation, so reciprocally clamped the capillary 20 at the temperature measuring head place of the refrigerant piping 16 of evaporimeter 10 and evaporimeter 10.And the capillary 20 at the refrigerant piping 16 of the device 10 that can avoid evaporating and the temperature measuring head place of evaporimeter 10 is deviate from.
In the above description, though the interval h of carrying tablet 27 is uniformly-spaced, not to be necessary for uniformly-spaced, for example,, also can dwindle this interval for the intensity that the end of improving carrier 26 is located.In addition, though, also a plurality of identical upside carrying tablet 27a and downside carrying tablet 27b can be set continuously on the end of carrier 26 along axial upside carrying tablet 27a and the downside carrying tablet 27b of being provided with that carries fulcrum 30 interlacedly.
This carrier 26 is to form with resin material is integrally moulded, the following describes this forming method.Fig. 9 is the mould key diagram in this forming method.Fig. 9 (a) shows the state that mould 31 is assembled molded carrier 26, and Fig. 9 (b) shows the state that mould 31 is separated.In the present embodiment, mould 31 is two moulds that are made of last side mold 31a and following side mold 31b.That is, carrier 26 is by making from the last side mold 31a of two directions of establishing carrying tablet 27 and two moulds of following side mold 31b.
As can be known, the mould divisional plane 32 of last side mold 31a and following side mold 31b is set like this from Fig. 9 (a), and the position that makes this face and upside carrying tablet 27a be installed to the installation portion bottom on the carrying fulcrum 30 coincide.Be installed at downside carrying tablet 27b on the position on the installation portion top on the carrying fulcrum 30, setting for only is that this part and this divisional plane coincide.And the major part of mould divisional plane 32 is positioned at the top of the center of carrying fulcrum 30.
Figure 10 shows the sectional view of Fig. 9 each several part, and Figure 10 (a) is the sectional view of the E-E line of Fig. 9, and Figure 10 (b) is the sectional view of the F-F line of Fig. 9, the sectional view of the G-G line of Figure 10 (c) figure.In Fig. 9, with regard to last side mold 31a and following side mold 31b, showing briefly only is the part relevant with carrying fulcrum 30 and carrying tablet 27.
From Figure 10 (a) as can be known, on the cross section part of carrying fulcrum 30, the mould divisional plane 32 of last side mold 31a and following side mold 31b is positioned at the top of the center of carrying fulcrum 30.In addition, also can know from Figure 10 (a), in the left part of upside carrying tablet 27a, the mould divisional plane 32 of last side mold 31a and following side mold 31b is positioned at the top of the center of carrying fulcrum 30, and last side mold 31a becomes the part on the installation portion bottom 33 that is positioned at upside carrying tablet 27a.Similarly, shown in Figure 10 (c), on the cross section part of downside carrying tablet 27b, the mould divisional plane 32 of last side mold 31a and following side mold 31b is positioned at the bottom of the center of carrying fulcrum 30.Following side mold 31b becomes the part on the installation portion top 34 that is positioned at downside carrying tablet 27b.
Like this, because carrier of the present invention 26 is by last side mold 31a and integrally moulded the forming of following side mold 31b, so can obtain to bear fully the intensity of reversing that the axle that carries fulcrum 30 is gone up the axle direction of rotation that produces.Because two moulds 31 by last side mold 31a and following side mold 31b are made carrier 26, therefore, the moulding ratio is easier to.
Yet, in the present embodiment, at a leading section capillaceous of survey ice sensor 17, be that temperature measuring head 18 is when being fixed on the front of evaporimeter, consider the running efficiency of dehumidifier, shown in the schematic diagram of Figure 11, temperature measuring head 18 will leave the refrigerant piping 16 certain distance E of evaporation 10.This is a value that makes compressor 14 runnings in the duration of runs of the dehumidifying effect that can guarantee sad temperature device apart from E as described later like that the biglyyest, and this value can be tried to achieve by experiment.
When the temperature measuring head 18 of surveying ice sensor 17 is provided in the certain distance that leaves refrigerant piping 16, can not make detecting operation when on refrigerant piping 16, only tying one deck by the ice a that approaches so shown in the 2 pecked line S, therefore, compressor does not shut down at this moment.Ice adds layer gradually, forms by the so thick ice b shown in the 2 pecked line L, and (shows the contact-making surface that the temperature measuring head 18 of surveying ice sensor 17 contact with ice with T among the figure) when surveying ice sensor 17 and contact, surveys ice sensor 17 and reacts with regard to generation, carries out detecting operation.At this moment, close the gauge tap 25 on the drive circuit that is installed in compressor 14 for example, compressor is shut down.
Hence one can see that, be deferred to ice grow to survey one-tenth that ice sensor 17 contact long-time after, just can carry out to compressor stop to control.That is, can utilize the ice of growth to replace timer.If so, just can not use existing microcomputer and defrost clock, also can on evaporimeter 10, have in the appropriate time of a certain amount of ice compressor 14 is stopped control reliably.
Be installed in more position if will survey ice sensor 17 near the refrigerant piping 16 of evaporimeter 10, the position shown in the 2 pecked line S for example, during perhaps than more inboard position, this position, even still can move owing to survey ice sensor 17 when only adhering to the very thin ice of one deck on the refrigerant piping 16, therefore, compressor 14 will stop continually, therefore, shorten the duration of runs of compressor, and the time of dehumidifying shortens similarly, and this running can cause dehumidifying effect to descend.
On the other hand, be installed in further from the position of the refrigerant piping 16 of evaporimeter 10 when surveying ice sensor 17, the position shown in the 2 pecked line L for example, during perhaps than more laterally position, this position, even whole refrigerant piping 16 becomes the state that has covered the thick ice of one deck, but more than ice grows to certain thickness, other thickness is not very very thick, therefore ice front end and can not contact, survey ice sensor 17 and also just can not move with surveying ice sensor 17.Therefore, compressor 14 just can not shut down, and still can ceaselessly turn round down.
And under the situation of having tied the thick ice of one deck on the refrigerant piping 16, in dehumidifier remained in operation, heat-exchange capacity descended, and evaporimeter 10 can not make the condensate moisture in the room air, so dehumidification rate can descend.
Therefore, in the present invention, consider above-mentioned factor, be fixed on suitable apart from the refrigerant piping 16 of evaporimeter 10 surveying ice sensor 17 apart from the E place.Should set ideal distance E like this, along with the ice that invests on the refrigerant piping 16 is grown up, the heat-exchange capacity of evaporimeter 10 drop to rapidly must defrosting thick ice the time, survey ice sensor 17 just moves, and the thickness that will ice is as standard thickness.
When will survey ice sensor 17 set for apart from refrigerant piping 16 set in the above described manner apart from E the time, when on refrigerant piping 16, adhering to ice, compressor does not shut down, from this constantly, be deferred to always ice grow to the one-tenth of the suitable thickness of this distance long-time after, compressor just shuts down, because compressor can run to the limit time point that must defrost, therefore the running efficiency height can turn round to make dehumidifier with guaranteeing maximum dehumidifying effect.
If change this distance, the one-tenth of ice also and then changes for a long time, surveys the time that ice sensor 17 detects ice by adjusting, and just can set the distance of surveying ice sensor 17 and refrigerant piping 16 aptly, also can freely adjust the duration of runs of compressor 14.
Like this,, can access and positively detect ice layer thickness, adjust the survey ice production apparatus of the simple structure of the duration of runs easily by being installed in apart from the suitable distance of evaporimeter 10 surveying ice sensor 17.
The installation site of surveying the temperature measuring head 18 of ice sensor 17 is not limited to laterally to be provided in refrigerant piping 16 places of the evaporimeter 10 of Fig. 2, dehumidifier front face side shown in Figure 3, as shown in figure 12, also can be installed in refrigerant piping 16 places that longitudinally set.Or shown in Figure 13,14, from below the switch cavity of the upper inner that is formed on body housing of holding switch SW etc., with the supporting slice 36 of the nearer distance of evaporimeter 10 in the face of the sagging formation one in ground, lower horizontal ground at this supporting slice 36 stretches out 2 holding pieces 37 up and down, clamp the temperature measuring head 18 of surveying ice sensor 17 by these holding pieces 37, and be fixed in be equipped on evaporimeter 10 vertically on refrigerant piping 16 near the position.
Like this, the temperature measuring head 18 of surveying ice sensor 17 does not contact with the refrigerant piping 16 that longitudinally sets, survey ice sensor and be bearing on the installing component 39 that influences that is not subjected to conduct heat, therefore survey ice sensor and not influenced by the heat transfer of refrigerant piping 16, this survey ice sensor 17 can operate well.
Below, illustrate that response is installed near the survey ice sensor 17 the evaporimeter 10, makes the control circuit of the dehumidifier of compressor 14 or Defrost heater 41 on/off.
Figure 15 is its control circuit, has been connected in series compressor drive circuit 40 and Defrost heater circuit 42 between power line G, G '; Compressor drive circuit 40 is made of compressor 14 that is connected in parallel and fan electromotor 12, Defrost heater circuit 42 is above-mentioned gauge taps 25 in parallel on Defrost heater 41, utilizes this gauge tap 25 to switch and makes 41 one-tenth short-circuit conditions of Defrost heater or become the energising heated condition.The 43rd, running electric capacity, the 44th, overload protection relay system.
Above-mentioned gauge tap 25 because ice is not also grown up, is cutting out shown in the figure solid line when bellows 17 of survey ice sensor 17 is extending when normal operation like that, makes 41 one-tenth short-circuit conditions of Defrost heater.The running current Ia that flows through compressor 14 and fan electromotor 12 flows away through the short circuit that this gauge tap 25 forms, and does not flow through this Defrost heater 41.On the other hand, detect when freezing, short circuit has been cut off in opening like that shown in the chain-dotted line among 25 one-tenth figure of gauge tap, and Defrost heater 41 energisings are flow through heater 41, heater 41 heatings from the current Ib of power supply after by compressor and fan electromotor.
In this Defrost heater circuit 42, when gauge tap 25 disconnects and Defrost heater 41 heater 45 of switching on simultaneously be connected between this fixed contact 22 and the travelling contact 21, be provided with in parallel with Defrost heater 25.As shown in Figure 4, this heater 45 is configured near the position of the bellows 19 of surveying ice sensor 17, and when the after-current Ic that therefore switches on flow through, bellows 19 gas on every side of ice sensor 17 was surveyed in heating, during defrosting, make the temperature height of the temperature maintenance of bellows 19 than temperature measuring head.Like this, because by heater 45 heating bellowss 19, so, can carry out stable heating compared with the situation that heats bellows 19 with the steam heat of the evaporimeter 10 that is subject to wind effect, the detection response that also can positively defrost when finishing is moved.Heater 45 can use thermistor constant resistance element.
Yet, when dehumidifier defrosts running, must make the compressor stall, connect Defrost heater 41, carry out this control with following device among the present invention.
That is, when opening gauge tap 25 and connect Defrost heaters 41, make voltage drop Va on the Defrost heater circuit 42 significantly greater than the (design circuit of Va＞Vb) of the voltage drop Vb on the compressor drive circuit 40 with the circuit of Figure 15.That is, make the resistance value of the all-in resistance R of Defrost heater 41 and heater 45 want the internal resistance of ratio piston compressor drive circuit 40, the much bigger (R＞r) of the internal resistance r of ratio piston compressor 14 in fact.
If like this, when defrosting, between Defrost heater 41, produce the voltage drop that equates with supply voltage E substantially, just become to compressor 14 and apply the low-voltage state that is lower than for drive compression machine 14 necessary operating voltages, compressor 14 can not be driven and stop.If design circuit needn't drive, stop special-purpose on-off switch by plug-in mounting so on compressor circuit 40 like this, circuit constitutes simple, and cost also can descend in addition.
46 is that lamp is used in the running demonstration, is connected between power line G, the G ' by resistance 47, unilateral diode 48.The 50th, running switch, the 51st, Thermal Cutoffs, the 52nd, the full water switch that when the dehumidifying water receptacle is filled one glass of water, moves, the 53rd, attaching plug.
Control circuit is as implied above when turning round, and the running switch SW is connected, compressor, fan electromotor 12 actions, dehumidifier when running because on the evaporimeter 10 between the no ice age evaporator temperature higher relatively, by its inner working gas that expands bellows 19 is extended so survey ice sensor 17, travelling contact 21 contacts with fixed contact 22, gauge tap 25 is to continue closure like that shown in the solid line, revolution electric current Ia flows through gauge tap 25 like that with shown in the arrow in scheming, and keeps running well.
Yet, when the ice on the evaporimeter 10 increases thickening, detect evaporator temperature by the temperature measuring head of surveying ice sensor 17 and descend, the working gas that simultaneous temperature reduces shrinks, bellows 19 shortens, and travelling contact 21 and fixed contact 22 disconnect, and 25 one-tenth dot-dash states of gauge tap disconnect.At this moment, current Ib flows to Defrost heater 41 with the diagram direction of arrow, Defrost heater 41 energisings, and the heater heating defrosts to evaporimeter 10.At this moment because the resistance value of Defrost heater 41 resistance of ratio piston compressor 14 is much bigger as described above, only applying the voltage below the driving voltage between the compressor, so compressor is forced to shut down.And, because of the disconnection of gauge tap 25, also flow to heater 45 by fixed contact 22 and travelling contact 21 electric currents, heater 45 heatings, the bellows 19 of ice sensor 17 is surveyed in the heating of the heat that sends, keeps the temperature higher than near the temperature measuring head that is in low-temperature condition the evaporimeter 10 18.
When defrosting proceeded to fast end, evaporator temperature rose and occurs changing.Because this variations in temperature expands working gas, bellows 19 elongations are restored, and survey ice sensor 17 gauge tap is connected, so compressor and fan electromotor 12 drive again, dehumidifier restarts running.
At this moment, because bellows 19 is stably heated by heater 45, be kept above the temperature of temperature measuring head 18, can carry out the reliable detection action so survey ice sensor 17, dissolve at ice temperature measuring head 18 has just been exposed under the situation of a bit, survey ice sensor 17 and can misoperation not make compressor have the situation of ice to turn round once more residual, icing complete obiterations from temperature measuring head 18, when the defrosting running that the ice of evaporimeter 10 does not almost have finished, compressor was just started once more, has carried out the high control of reliability.
