Embodiment 1.

Fig. 1, the 2nd, the figure of expression embodiment 1, Fig. 1 is the structure diagram of refrigerator, Fig. 2 is the flow diagram of expression deodorizing, sterilization running control.In the drawings, the 1st, refrigerator, this refrigerator 1 will and be filled in body of thermal insulating box 5 partitions that their intermediary foam-thermal insulations 4 make with outer container 2, interior case 3 and become a plurality of chambers, have the door body of the peristome of each chamber of switch ground sealing freely.

Refrigerator 1 from the top down successively partition become refrigerating chamber 11, ice-making compartment 12 and switch room 13, vegetable compartment 16 and refrigeration chamber 18.And these chambers have refrigerating-chamber door body 6, ice-making compartment door body 7, switch room door body 8, vegetable compartment door body 9 and the refrigerating chamber door body 10 of its peristome of switch ground sealing freely.

Become the partition spare of a plurality of chambers to have body of thermal insulating box 5 partitions: the partition spare 19 of the partition spare 17 of the partition spare 15 of the partition spare 14 of refrigerating chamber 11 and ice-making compartment 12 and switch room 13, ice-making compartment 12 and switch room 13, ice-making compartment 12 and switch room 13 and vegetable compartment 16, vegetable compartment 16 and refrigeration chamber 18.

In refrigerating chamber 11, dispose water supply box 20.In the cooling room that the rear of water supply box 20 and vegetable compartment 16 forms, be provided with water cooler 21 and box fan 22.Be provided with the refrigerating chamber that is used to adjust from the cooling room to the refrigerating chamber 11 cold air flow with setter 23 and the switch room that is used to adjust the cold air flow of going to switch room 13 with setter 24.

In refrigerator 1, interior rear at ice-making compartment 12 is equipped with ice making angle 25, and ice making angle 25 possesses: the outer wall spare 28 of ice-making disc 26, the wheel casing 27 that is used to reverse ice-making disc 26, supporting ice-making disc, whether detect in the storage ice chest 31 be arranged in the ice-making compartment 12 test rod 29 of full ice.The 30th, from the passage-water channel of the water of water supply box 20 when ice-making disc 26 is supplied with water, the 31st, ice is stored at storage ice chest in the ice-making compartment 12.The 39th, the lid of water supply box.

Have display panel 32 on the surface of refrigerating-chamber door body 6, on display panel 32, possess ice making switch on and off 33.Can stop ice making by disconnecting this ice making switch on and off 33.

Be provided with water-purifying filter 41 in water supply box 20, water-purifying filter 41 has photocatalyst-titanium oxide.The only ultraviolet ray of excitation titanium oxide.As ultraviolet rays emitting apparatus, with the ultraviolet photodiode 34 that sends wavelength with about 380nm be arranged on the water supply box 20 of water-purifying filter 41 opposed positions or water-purifying filter 41 near body of thermal insulating box 5 (case 3 or partition spare 14 etc. preferably) on.On display panel 32, be provided with the photodiode switch on and off 35 of open and close photodiode 34.Compare with other uviolizing means such as black lamp, 34 life-spans of photodiode are long, because longer than the life-span of refrigerator generally speaking, so, do not need to safeguard.In addition, because volume is little, can reduce to be provided with space, accommodation space.

Water-purifying filter 41 has the effect of smelly root one chlorine, three methyl halides or assorted bacterium etc. of planar water forcefully.When photocatalyst is had the rayed of certain wavelengths, become excited state, the surface has very strong oxidation capacity.For example, a kind of-titanium oxide of photocatalyst is illuminated when having wavelength ultraviolet of 380nm, becomes excited state, and the surface has very strong oxidation capacity.By this oxidation capacity, from water or oxygen, produce atomic group, this atomic group decomposes the organism contain bacterium etc. by redox reaction, brings into play deodorizing and anti-microbial effect thus, therefore, can make not have disagreeable stink, also the mix ice of health of bacterium etc.

Water-purifying filter 41 is made the structure that covers activated carbon fiber with non-woven fabrics, on non-woven fabrics, also titanium oxide can be arranged.So, though since activated carbon fiber through life-time service can be not destroyed yet (owing to cover activated carbon fiber, so the fiber of activated carbon fiber can not flow in the water) with non-woven fabrics, so, can obtain the high refrigerator of reliability.

Can use the photocatalyst of titanium oxide material in addition as water-purifying filter 41, as long as energy exciting light catalyzer, light is that visible light is also passable.

In addition, ultraviolet ray has germicidal action, because the fugitive more fruit of this sterilization effect wavelength is good more, so wavelength is short more good more, but, use for example ultraviolet ray of the wavelength below the 280nm at present embodiment.If use the following ultraviolet ray of 280nm, even water-purifying filter 41 does not use photocatalyst can obtain sufficient sterilization effect yet.

By the combination of above effect, can carry out deodorizing and sterilization to the water in the water supply box 20, and make the ice of cleaning all the time automatically with not needing to safeguard.

In addition, because photodiode 34 volumes are little, so, can not take unnecessary accommodation space.Have, photodiode 34 is not owing to resemble and have toxicity the mercuryvapour lamp, so be safe again.The ultraviolet ray of sending from photodiode 34 can shine the water in water-purifying filter 41 or water supply box 20, the water supply box 20.Water-purifying filter 41 is arranged in the water supply box 20.As water-purifying filter 41, has photocatalyst-titanium oxide with activated carbon on its surface.Though photodiode 34 the position is set also in water supply box 20 owing to be electric component, so, unsatisfactory.In addition, water supply box 20 usefulness have the material that can see through characteristic ultraviolet to be made, so, can see through ultraviolet ray.

In addition, also can design the transmitter whether water or sensed water level are arranged in the UV detection water supply box 20 that utilizes photodiode 34 to send.In addition, except ultraviolet ray, also the photodiode of the light beyond the emission ultraviolet ray can be arranged on the photodiode mounting plate, utilize this light as transmitter.

Followingly its action is described according to Fig. 2.Fig. 2 is the flow diagram of control action expression embodiments of the invention 1, the expression refrigerator.In the drawings, step S21 be carry out running condition whether be stop ice-make mode judgement stop the ice-make mode determination step.At this, the user for example is arranged on change or the setting that the ice making switch stops ice-make mode that stop on the operating panel by operation (connection).In stopping ice-making process, do not carry out ice making control (ice making, an ice, water supply).

At step S21, be judged to be the occasion that is not to stop ice-make mode, enter beginning ice making determining step-step S25, carry out ice making control.At step S25, judge whether to be to have passed through the specified time (for example, about 80～150 minutes, preferably about 100 minutes), and the temperature of ice-making disc is whether (for example-10 ℃ below) below the specified temperature from the beginning ice making.In the occasion of the condition that does not satisfy step S25, turn back to step S21.In the occasion of the condition that satisfies step S25, enter ice-making compartment and completely ice determining step-step S26, judge whether completely ice of ice-making compartment 12.At this moment, by making the height that moves up and down, detects its decline through the inspection ice bar 29 of other approach setting, carry out the detection of the pondage in the ice-making compartment 12.

At step S26, be judged to be the occasion that ice-making compartment 12 is full ice, enter and light LED sterilization steps-step S27, photodiode (LED) 34 is only lighted the specified time, water-purifying filter 41 is sterilized.Then, at step S27, after lighting photodiode 34, access door switch determining step-step S28 judges whether the door of ice-making compartment 12 has switch motion.

At step S28, at door the occasion of switch motion is arranged, turn back to step S26, there is not the occasion of switch motion at door, carry out step S28 repeatedly.Therefore, if door is done switch motion, photodiode 34 is lighted specific time, so, even under the situation of ice-making compartment 12 full ice, also can sterilize to water-purifying filter 41.In addition, even owing to continuing completely also to light photodiode 34 under the ice state, so, even under the state that continues full ice, the state of photodiode 29 can not appear not lighting, can sterilize, and therefore, the user is edible ice relievedly.

At this, at step S26, in being judged as ice-making compartment 12, or not the occasion of full ice, enter ice making and fold ice step-step S29, the ice that rises of doing the ice that trips out in the ice-making disc 26 moves, and is received in the ice-making compartment 12 by ice-making disc 26 interior ice are fallen.And, enter ice-making disc water supply step-step S2A, after ice-making disc 26 supplies water, enter and light LED sterilization steps-step S2A, only light 34 specified times of photodiode (LED), sterilize, turn back to step S21.Therefore, owing to supply water at every turn, photodiode 34 is just lighted the specified time, so each water supply can both be sterilized to water-purifying filter 41.

At this, at step S21, be judged to be the occasion that stops ice making, enter specified time counting step-step S22, the statistics specified time (for example about 100 minutes).Through specified time for example after 100 minutes, enter and prevent that inspection ice bar from freezing step-step S23, freeze in order to prevent inspection ice bar 29, make 29 actions of inspection ice bar.Then, enter and light LED sterilization steps-step S24, light photodiode 34, can sterilize water-purifying filter 41.Then, turn back to step S21, carry out above-mentioned action once more repeatedly.

Because by carrying out above such control, even in stopping ice-making process, do at every turn and prevent to examine the action that ice bar 29 freezes, all light photodiode (LED) 34, therefore, even in water supply box 20, water is arranged, and keep stopping the occasion of ice making state for a long time, also can sterilize reliably.

As previously discussed, in Fig. 2, though the control flow chart of the ice making of present embodiment action is illustrated,, shown in Figure 3 is or not another example of the control flow chart under the full ice condition condition in the ice-making compartment 12.In Fig. 3,, judge that compressor is whether in operation process at compressor operation determining step-step S1.At step S1, be judged to be the not occasion in operation process of compressor, stopping to stop water supply to ice-making disc water supply step-step S8.Be judged to be the occasion of compressor in operation process at step S1, access door body switch determining step-step S2.At step S2, judge whether door of refrigerator body 10 is to close.At step S2, be judged to be the occasion that door of refrigerator body 10 is not being closed, turn back to step S2.At step S2, be judged to be the occasion that door of refrigerator body 10 is being closed, enter ice-making compartment and completely ice determining step-step S3.

At step S3, judge whether ice is full in the ice-making compartment 12.At step S3, ice is full occasion in being judged to be ice-making compartment 12, enters step S8, stops to supply water.At step S3, ice is not full occasion in being judged to be ice-making compartment 12, enters starting timing register step-step S4.Step S4, instrumentation is connected the timer initiation (connection) of the time of photodiode 34.After step S4, enter and light photodiode (LED) sterilization steps-step S5.At step S5, photodiode 34 is connected, and begins sterilization.After step S5, enter and light photodiode time timing step-step S6.

Step S6 judges whether photodiode 34 has been connected the specified time.At step S6, do not connect the occasion of specified time being judged to be photodiode 34, turn back to step S6.At step S6, connected the occasion of specified time being judged to be photodiode 34, enter water supply start step-step S7.At step S7, the electromagnetic pump motor entry into service of working shaft, water supply start.Owing to by carrying out control shown in Figure 3, before just wanting ice making, the water in the water supply box 20 is carried out deodorizing and sterilization,, can provide the ice of health to the user so the user can be relieved.

As previously discussed, by lighting photodiode (LED) 34, and light photodiode 34 specific times, can obtain sufficient sterilising effect, in addition, light LED34 with satisfying the life-span in specified action (or determine time).For example, the life-span of common LED34 is about 60,000 hours, so, for the LED34 that lights after the full ice detection of step S27, be 1 time at specific time (about 100 minutes) at interval owing to supply water, so, in the period of product guarantee phase-10, even light 30 fens clock times at every turn, the time of lighting also is about 26000 hours, so no problem at all.

At this, if the door switch average time under the actual service condition is the words of object with all doors, because be about about 70 times every day, so, with open refrigerator any one light the occasion of LED34 synchronously, approximately carry out No. 250,000 times switch during 10 years.Because the illumination of LED34 is mapped to water-purifying filter 41, when lighting about 2 minutes, can obtain sufficient sterilising effect, so, if the time of lighting is provided with restriction, make it only light the specified time (for example 5 minutes), then the life-span of LED is no problem fully.

Therefore,, light LED34 specific time (for example 5 minutes), the just 21000 hours time of lighting in the period of 10,, also can satisfy fully its life-span even used for 10 years even for example detect back and switch behind the door at full ice.

At this, the time of lighting of LED34 shown in the flow diagram of Fig. 4 like that, preferably synchronous with the connection (or disconnection) of box fan 22.Fig. 4 is that the LED of the refrigerator of expression present embodiment lights the sequence of control skeleton diagram of time.

Below the action of Fig. 4 is described.In Fig. 4, at box fan running determining step-step S31, judge that box fan 22 whether in action (connection), as if being anastomosing at step S31 box fan 22, then enters and lights LED step-step S32, light LED34.At step S31, do not move the occasion of (connection) being judged to be box fan 22, enter the breath LED step-step S33 that goes out, the breath LED34 that goes out.

At present embodiment, owing to make the running of lighting LED34 and box fan 22 synchronous, so, can connect, disconnect LED34 with the interval of appropriateness, can sterilize fully to water-purifying filter 41.At this, if establish the annual average out to 60% of the operation factor of box fan 22, then used for 10 years, the time of lighting of LED34 is approximately 52500 hours, because less than 60000 hours, so, can guarantee that in the life time of LED34, LED34 can not damage halfway, in addition, to the sterilization of the water in the water supply box 20, when antibiotic, can guarantee lighting the time of sufficient LED34.

In addition, the time of lighting of LED34 also can be shown in the flow diagram of Fig. 5 like that, with opening the door synchronously of refrigerator.Fig. 5 is that the LED of the refrigerator of expression present embodiment lights another sequence of control skeleton diagram of time.

Below the action of Fig. 5 is described.Fig. 5 is that another LED of the refrigerator of expression present embodiment lights the sequence of control skeleton diagram of time.In Fig. 5, judge at door switch determining step-step S41 whether any one door of refrigerator is being opened, at step S41, be the occasion of opening being judged to be door, enter and light LED sterilization steps-step S42, light LED34, sterilize.At step S41, be judged to be the occasion that Men Weikai, enter the breath LED step-step S43 that goes out, the breath LED34 that goes out.

At present embodiment, owing to make it and open the door synchronously (with closing the door synchronously) to light LED34, so, tap water is supplied under the situation of water supply box the user, can light LED34 after this, to sterilizing in water-purifying filter 41 and the water supply box 22 at once.Therefore,, can light LED34 after this at once, sterilize reliably even assorted bacterium flow in the water supply box when opening.Have again, owing to synchronously light LED34 with opening the door, so, except the user can confirm the action (can confirm whether to have lighted LED34) of LED34 at any time, even in the refrigerator manufacturing processed, when on production line, testing, can there be other restrictedly to light the inspection of LED34 only by opening door yet.

At the foregoing description, though what enumerate is the lighting the time of each LED34, make LED34 light the example of specified time continuously,, the method for bright lamp also can be flicker or light continuously after flicker.Owing to the lighting method that makes LED34 is flicker or lights continuously after flicker, so, because the user is watching the flicker of LED34 attentively, can see the action of LED34 more reliably.

At the foregoing description, though what enumerate is the example of lighting 1 LED34,, also a plurality of LED34 can be set, light them simultaneously.Because light a plurality of LED34 simultaneously, so, having improved near the brightness of water supply box, visibility meter has improved, and in addition, can improve the sterilising effect of LED34.
