Abstract
The invention provides a refrigerator, which can reduce the consumption of power through effectively conducting light-emitting control of a lighting unit for activating photocatalyst. A storing chamber is provided with an air sensor which detects the air concentration of the air to be processed by means of the photocatalyst of organic air and/or odor. The state of the storing chamber can be determined by the detecting value of the air sensor. Under the situation that the concentration of the target air is lower than the regulated value, the light emission of the lighting unit for activating the photocatalyst can be inhibited or stopped. The necessity of the activating of the photocatalyst can be determined based on the air concentration of the detected target air. Accordingly, energy saving can be improved through effectively controlling the lighting unit and inhibiting the use of power.

In addition, at the rear of ice making water receptacle 22, be provided with ice making water pump 28.At the rear of extracting case 23 out, and, in the space of the side, rear portion of seal storage chamber 24, dispose the negative pressure pump 29 as an example of the decompressor for being reduced pressure in seal storage chamber 24.This negative pressure pump 29 is placed in storage box (omitting in figure), in storage box except negative pressure pump 29, also be equipped with in carbon dioxide sensor 45(figure and omit), different according to the concentration of carbon dioxide around, the electric output of this carbon dioxide sensor 45 can change.
This carbon dioxide sensor can be used any of semiconductor-type, solid electrolyte formula, infrared-type, in the present embodiment, uses semiconductor-type.
In the present embodiment, with the air that utilizes negative pressure pump 29 to attract in seal storage chamber 24, and the mode of the surrounding of the carbon dioxide sensor 45 of the oxygen diffusion that makes this attraction in storage box is configured, the electric output of carbon dioxide sensor 45 detects action when negative pressure pump 29 action (ON).In addition, negative pressure pump 29 is connected with the pump connecting portion that is arranged at the side of seal storage chamber 24 via conduit.
In addition, as shown in Figure 2, above-mentioned seal storage chamber 24 is configured to be had: the seal storage chamber main body 40 of case shape, and it has the peristome (put into and take out food peristome) that takes out food for putting into; Seal storage chamber door 50, it opens and closes putting into of seal storage chamber main body 40 and takes out food peristome; Food service tray 60, portion is equipped with food within it, by seal storage chamber door 50, this food service tray 60 is put into seal storage chamber 24 or from 24 taking-ups of seal storage chamber.That is, in seal storage chamber main body 40, by 50 sealings of above-mentioned seal storage chamber door, put into and take out food peristome, make to be formed by the space of seal storage chamber main body 40 and 50 encirclements of seal storage chamber door the low-voltage space of decompression.In addition, food service tray 60 is arranged on the back side one side of seal storage chamber door 50, and the movement that can be accompanied by seal storage chamber door 50 moves forward and backward.
By placing food and close seal storage chamber door 50 on above-mentioned food service tray, make the inside of seal storage chamber 24 in air-tight state, and then, open the door on-off switch of the switching that detects refrigerating-chamber door, drive negative pressure pump 29, reduced pressure in seal storage chamber 24, be decompressed to pressure in seal storage chamber 24 in subatmospheric state.Thus, can make the oxygen concentration in seal storage chamber 24 decline, prevent the deterioration of the nutritional labeling in food.
After state in seal storage chamber 24 in airtight and decompression, by lighting the light emitting diode 46 that is arranged at top, activate the photochemical catalyst being coated on surface plate 52.Its result is foul smell composition and organic gas in food can be changed into carbon dioxide, thereby realize the deodorizing in closed container.In addition, by making in closed container, under the very high inert environments of gas concentration lwevel, can to suppress the enzyme of food and the activity of cell such as meat or vegetables.

Then, utilize Fig. 5, the control method of switching temperature in the refrigerator of the present embodiment is described.In addition, Fig. 5 is for the controlling party block diagram of control method of the refrigerator of the present embodiment is described.
In Fig. 5, by the control device 46 forming such as microcomputer etc., using by detect refrigerating chamber 2 temperature the detected temperature of temperature sensor 42 and by being set with storeroom, be that the temperature set of the temperature regulation section 44 of the temperature of refrigerating chamber 2, refrigerating chamber 3, refrigerating chamber 4, vegetable compartment 5 is as input, based on these temperature, to retaining device 41 and heater 43 output control signals.In addition, seal storage chamber 24 can be between ice Wen Wendu band and refrigerated storage temperature band switching temperature.
Due to as mentioned above, control device 46 consists of microcomputer, so the various controls of the light emitting control of temperature control (baffle controls, heater control, compressor control etc.) and light emitting diode etc. are by being stored in built-in nonvolatile memory, for example the program in flash memory is carried out.
Specifically, in the situation that utilizing the detected detected temperatures of temperature sensor 42 lower than certain fiducial temperature A, by reducing aperture or the complete closing baffle plate device 41 of retaining device 41, control (inhibition) air conditioning quantity.In addition, in temperature, drop to too low in the situation that, give heater 43 energisings, the control that makes temperature increase.
On the contrary, in the situation that utilizing the detected detected temperatures of temperature sensor 42 higher than fiducial temperature A, by increasing the aperture of retaining device 41, the cold air free air space cool-air feed in seal storage chamber 24, reduces the control of the temperature in seal storage chamber 24.
In addition, in the present embodiment, in temperature adjustment part 44, can be set in " automatic mode " automatically switching between ice Wen Wendu band and refrigerated storage temperature band, the switching of the storage temperature band of food is that the electric output based on carbon dioxide sensor 45 decides.
For example, by light emitting diode 46, do not throwing light on, photochemical catalyst is not brought into play under the state of catalyst function, in the situation that vegetables being placed in seal storage chamber 24, the respiration by vegetables within the stipulated time of stipulating in advance rises the gas concentration lwevel in seal storage chamber 24.Under this state, by negative pressure pump 29 action (ON) is introduced the air in seal storage chamber 24 in storage box, and in surrounding's diffusion of carbon dioxide sensor 45, the electric output of carbon dioxide sensor 45 is declined.On the other hand, due in the situation that having preserved meat and/or fish, the respiration as vegetables not, so gas concentration lwevel at the appointed time does not change substantially, therefore, electric output does not have much variations.Now, because catalyst function is inoperative, so do not change into carbon dioxide from organic gas and the foul smell composition of meat and/or fish.
By utilizing this characteristic, can distinguish the attribute of food, for example distinguish meat and/or fish and vegetables.; carry out following control: under the state not throwing light on by light emitting diode 46; in the situation that the electric output of carbon dioxide sensor 45 declines; what be judged as preservation is vegetables; switch to refrigerated storage temperature band; in the situation that electric output does not have much variations, what be judged as preservation is meat and/or fish, automatically switches to ice Wen Wendu band.Thus, can be set in " automatic mode " automatically switching between ice Wen Wendu band and refrigerated storage temperature band.
Then,, after finishing the judgement of food, start, to light emitting diode 46 energisings, to activate the photochemical catalyst being coated on surface plate 52.As mentioned above, if owing to putting into food, the deodorization because of photochemical catalyst produces carbon dioxide, so the gas concentration lwevel in seal storage chamber 24 rises.As long as keep the state in sealing in seal storage chamber 24 just to continue to light emitting diode 46 energisings.
In seal storage chamber 24, constantly in the situation that of long-time air-tight state, the pressure rise causing for the small leakage of modifying factor closed container, regularly makes negative pressure pump action (ON), to reducing pressure in closed container.Now, if owing to putting into food, the effect by photochemical catalyst becomes carbon dioxide by the organic gas being produced by food with foul smell conversion thus, so the gas concentration lwevel in closed container rises, if the gas in closed container is introduced in storage box, the electric output of carbon dioxide sensor declines.In this case, owing to by photochemical catalyst, the organic gas from meat and/or fish being become to carbon dioxide with foul smell conversion, so the concentration of carbon dioxide has the trend increasing along with the time.
Yet, owing to there is no accommodating food in seal storage chamber 24 in the situation that, original organic gas and/or the foul smell composition of just not existing, even so by light emitting diode 46 exciting light catalyst, gas concentration lwevel can not change yet, the state that the electric output of carbon dioxide sensor remains unchanged.
By utilizing above-mentioned characteristic, can distinguish in seal storage chamber 24, whether to be placed with food (such as meat and/or fish, vegetables etc.).That is, carry out following control: in the situation that the electric output of carbon dioxide sensor 45 declines, be judged as in storeroom 24 and be equipped with food, by continuing, to light emitting diode 46 energisings, to make the deodorization continuous and effective of photochemical catalyst.
On the other hand, carry out following control: in the situation that the electric output of carbon dioxide sensor 45 does not change, be judged as and there is no accommodating food, by stopping to light emitting diode 46 energisings, make the catalyst function of photochemical catalyst invalid, thereby suppress power consumption.
At this, the present embodiment carries out the light emitting control of light emitting diode 46 by carbon dioxide sensor 45, as long as but can be the catalyst function of exciting light catalyst or the invalid judgement of catalyst function that makes photochemical catalyst, can not be carbon dioxide sensor 45.
Then, utilize Fig. 6 and Fig. 7 for detect the variation of the gas concentration lwevel in seal storage chamber 24 by carbon dioxide sensor 45, and then the method for control light emitting diode 46 describe.In addition, the negative pressure pump 29 of the action timing diagram based on shown in Fig. 7 and the control of light emitting diode 46 are to carry out by being stored in the program of the flash memory of microcomputer.
As shown in Figure 6, carbon dioxide sensor 45 is for having adopted the module of semiconductor-type carbon dioxide sensor that generates the electric output of 0～5V according to the concentration (ppm) of carbon dioxide around, for example, in the situation that the gas concentration lwevel in seal storage chamber 24 is Cx(ppm), from carbon dioxide sensor 45 output voltage V x(V).Control device 46, according to the value of this voltage Vx, detects the gas concentration lwevel in seal storage chamber 24, the control of the trip temperature of going forward side by side control and/or light emitting diode 46.
The carbon dioxide that the interior people's who is mixing the carbon dioxide that originally comprises, carbon dioxide that food produces and suck during at accommodating food in atmosphere expiration comprises in seal storage chamber 24 etc.Therefore,, only by measuring voltage Vx, the carbon dioxide that food can not be produced or the carbon dioxide increasing because of the catalyst action of photochemical catalyst branch away and detect.
By the action timing diagram shown in Fig. 7, to distinguishing the method for the generation reason of above-mentioned carbon dioxide, describe.
First, as shown in Figure 7 (a), when refrigerating-chamber door 6 is " pass " → " opening " → " pass ", be judged as the possibility of food accommodating, as shown in Figure 7 (b) shows, when refrigerating-chamber door 6 becomes " pass ", or through after the stipulated time, only drive the 29 action Ta times of negative pressure pump.Now, as shown in Fig. 7 (c), owing to stopping driving light emitting diode 46, so photochemical catalyst is in stopping the state of its catalyst function.
As shown in Fig. 7 (d), under this state, by negative pressure pump 29, be drawn into the carbon dioxide in the expiration that air in closed container mixing atmosphere and people, the concentration of carbon dioxide is Ca(ppm).
Therefore, as shown in Fig. 7 (e), because gas concentration lwevel is not very high, so the minimum of a value of utilizing carbon dioxide sensor 45 detected voltages in during driving negative pressure pump 29 is Va.(along with negative pressure pump 29 actions, the gas concentration lwevel that flows to carbon dioxide sensor 45 uprises, and therefore utilizes the detected voltage step-down of carbon dioxide sensor 45.) carbon dioxide that now the gas concentration lwevel Ca in detected seal storage chamber 24 is mixing the carbon dioxide comprising in atmosphere as above, comprising in the expiration people that flows into when accommodating food etc.Thus, the environment in seal storage chamber 24 is set to initial state, the benchmark using carbon dioxide now as judgement below.
After this, as shown in Figure 7 (b) shows, at interval for example, after the stand-by time of T1 time (dozens of minutes), again drive negative pressure pump 29 and only drive the Tb time, drive this negative pressure pump 29 during in the minimum of a value of voltage be Vb.(along with negative pressure pump 29 actions, the gas concentration lwevel that flows to carbon dioxide sensor 45 uprises, and therefore utilizes the detected voltage step-down of carbon dioxide sensor 45.) owing to now also stopping driving light emitting diode 46, so photochemical catalyst is in stopping the state of its catalyst function.
At this, in the situation that vegetables being placed in seal storage chamber 24, during the T1 time in respiration by vegetables make the gas concentration lwevel of closed container inside increase.On the other hand, in the situation that preserve the food that meat or fish etc. do not produce carbon dioxide, gas concentration lwevel does not change substantially.This is because even if produced foul smell composition or organic gas, the catalyst function of photochemical catalyst is the state in stopping still.Gas concentration lwevel in seal storage chamber 24 now rises to Cb(ppm as illustrated in Fig. 7 (d)).
Therefore, in control device 46 inside, when Vb=Va, can judge (deduction) for accommodating be meat or fish, can be when Va > Vb, judgement (deductions) be accommodating be vegetables.
In addition, the gas concentration lwevel sending from food represents with Va-Vb, and the value of Va-Vb is larger, and the climbing of gas concentration lwevel is higher.That is more vegetables, can be judged as accommodating.
At this, the driving time of negative pressure pump 29 is that the pass of Ta time and Tb time is the Ta time < Tb time.This be because, the time (Ta time) of initial driving negative pressure pump 29 is after refrigerating-chamber door 6 has carried out the action of " pass " → " opening " → " pass ", so the air pressure in seal storage chamber 24 uprises, when next driving negative pressure pump 29, (Tb time), reduces pressure to the air in seal storage chamber 24.That is, owing to having produced air capacity poor that flows to carbon dioxide sensor 45 according to the height of this air pressure, so make the Tb time elongated in order to improve accuracy of detection.
Then, as shown in Figure 7 (b) shows, only make the 29 action Tb times of negative pressure pump, after this, as shown in Fig. 7 (c), when stopping negative pressure pump 29, or through after the stipulated time, beginning, to light emitting diode 46 energisings, is supplied with luminous energy to photochemical catalyst, thus activated catalyst function.Under this state, the catalyst function by photochemical catalyst becomes carbon dioxide by the organic gas sending from vegetables, meat, fish etc. with foul smell conversion.Gas concentration lwevel in seal storage chamber 24 now rises to Cc(ppm as illustrated in Fig. 7 (d)).
After this, as shown in Figure 7 (b) shows, 2 times of interval T (several hours), again drive negative pressure pump 29 and only drive the Tc time, as shown in Fig. 7 (e), drive this negative pressure pump 29 during in the minimum of a value of voltage be Vc.(along with negative pressure pump 29 actions, the gas concentration lwevel that flows to carbon dioxide sensor 45 uprises, and therefore utilizes the detected voltage step-down of carbon dioxide sensor 45.）
At this, in the situation that food being placed in seal storage chamber 24, by irradiating the light sending from light emitting diode 46, carry out the catalyst function of exciting light catalyst, make the gas concentration lwevel of the inside of seal storage chamber 24 increase, on the contrary, in the situation that there is no accommodating food, gas concentration lwevel is substantially constant.That is, in control device 46 inside, when Vc=Vb, can be judged as and there is no accommodating food, when Vb > Vc, can be judged as the food that is equipped with vegetables, meat, fish etc.In addition, the STA representation of Fig. 7 is equipped with food, therefore continues to light emitting diode 46 energisings.
Therefore, be judged as be equipped with food in the situation that, continuing, to light emitting diode 46 energisings, to photochemical catalyst, to supply with luminous energy, being judged as there is no accommodating food in the situation that, stopping to light emitting diode 46 energisings, thereby stop providing luminous energy to photochemical catalyst.
In the above described manner, by under the state of exciting light catalyst not, interval T drives negative pressure pump 29 twice before and after 1 time, and can the gas concentration lwevel based on now changing judgement (deduction) be which kind of food has produced carbon dioxide.
In addition, under the state at exciting light catalyst, 2 times of interval T drive negative pressure pump 29 again, and the change in concentration of carbon dioxide that can be based on now detects the carbon dioxide that whether has the catalyst function because of photochemical catalyst to increase, thereby has or not food in judgement storeroom 24.Then, if be judged as in storeroom 24, there is no food, stop to light emitting diode 46 energisings, thereby can make the catalyst function of photochemical catalyst invalid, suppress power consumption.
In addition, in the present embodiment, if be judged as in storeroom 24, there is no food, stop to light emitting diode 46 energisings, but do not stop energising, but by reducing energising amount, reduce the generation of luminous energy, can suppress power consumption yet.
In addition, in the present embodiment, by 2 times of interval T, in Tb time and Tc, between the time, drive negative pressure pump 29, judge in seal storage chamber 24 and have or not food, but be not limited to this, the action that can also further append negative pressure pump 29 judges in seal storage chamber 24 and has or not food.
(embodiment bis-)
Then, utilize Fig. 8 to describe the second embodiment of the present invention, because the part of Fig. 8 and Fig. 7 repetition is a lot, so the part repeating is not described.
The semiconductor-type carbon dioxide sensor 45 that the refrigerator of explanation is used in the above embodiments one has following characteristic: according to sensor temperature or humidity around, the sensitivity of sensor changes, and its electric output also changes.
Therefore, if as shown in Figure 7, if temperature or humidity change, even if gas concentration lwevel increases, sometimes also can obtain the result that primary measured value Va approaches secondary measured value Vb, detect mistakenly gas concentration lwevel and do not rise.
At this, even if also can measure exactly the method for the gas concentration lwevel in seal storage chamber 24 in the situation that the temperature for around or humidity have been occurred to change, describe.At this, in Fig. 8, the switch of refrigerating chamber door, the "on" positions of the action of negative pressure pump 29, light emitting diode 46 etc. are identical with Fig. 7.
First, as shown in Figure 8 (a), the driving time of negative pressure pump 29 be the Ta time during in, measure maximum Vamax and the minimum of a value Vamin of the electric output of carbon dioxide sensor 45.And then, according to this measured value, try to achieve the variation delta Va=(Vamax-Vamin of electric output).
The detected value of the variation delta Va of the electric output of carbon dioxide sensor now 45 being regarded at Ta as to the gas concentration lwevel based on temperature, humidity in the time.
Maximum Vbmax, Vcmax and minimum of a value Vbmin, the Vcmin of the electric output of the carbon dioxide sensor 45 in similarly, detecting during Tb time and Tc time.And then, according to this measured value, try to achieve the variation delta Vb=(Vbmax-Vbmin of electric output).And, according to this measured value, try to achieve the variation delta Vc=(Vcmax-Vcmin of electric output).
Respectively the variation delta Vb of electric output now and variation delta Vc are regarded as to the detected value of the gas concentration lwevel based on temperature, humidity in the time in Tb time and Tc.
At this, because Δ Va, Δ Vb, Δ Vc are respectively the measured values of measuring under mensuration environment separately, so the variation of the electric output of having got rid of the impact of Yin Wendu, humidity and having caused, has obtained the variation of the electric output of the increase and decrease based on gas concentration lwevel.
Therefore, the in the situation that of Δ Va=Δ Vb, can be judged as and in seal storage chamber 24, preserve meat or fish or do not preserve any food, the in the situation that of Δ Vb > Δ Va, can be judged as T1 in the time gas concentration lwevel in seal storage chamber 24 rise, accommodating vegetables.In addition, the in the situation that of Δ Vb=Δ Vc, can be judged as and there is no accommodating food seal storage is indoor, the in the situation that of Δ Vc > Δ Vb, can be judged as at T2 and in seal storage chamber 24, be equipped with food in the time.
In addition, Δ Vb=Δ Vc not take and must be equated as condition, also comprises as long as be judged as situation about equally in the scope of the amplitude of regulation.
By above-mentioned assay method, can further improve the accuracy of detection of carbon dioxide sensor 45.
In addition,, in the present embodiment of the first embodiment and the second embodiment, to the refrigerator of photochemical catalyst and light emitting diode is set in seal storage chamber, be illustrated, but the invention is not restricted to this, the refrigerator that can also be applied to illustrate in the prior art.In a word, the present invention can be applied to have the refrigerator that throws light on the device of exciting light catalyst by lighting unit.
