Abstract

A refrigeration device, in particular a domestic refrigeration device, has a storage chamber, a cold generator which refrigerates the storage chamber, a temperature sensor for recording the temperature of the storage chamber, and a control unit which, in a thermostat operating mode (S1-S5), is designed to start the cold generator running (S2) when a first upper limit temperature (T+1) in the storage chamber is exceeded. The control unit can be temporarily switched into a low-noise operating mode (S7, S8) in which the operation of the cold generator is suspended even when the first upper limit temperature (T+1) has been exceeded.

Description

For the refrigerating appliance of low noise operation
The present invention relates to refrigerating appliance, Domestic refrigerator especially, this refrigerating appliance has storage chamber, makes the cooling refrigerating generator of described storage chamber, for the temperature sensor of the temperature of storage chamber described in sensing with control the control module of the operation of described refrigerating generator according to the temperature of temperature sensor institute sensing.Common in service at refrigerating appliance, described control module is as having sluggish comparator work, in the time of the first limes superiors temperature higher than storage chamber, this comparator puts refrigerating generator into operation, and, once lower than than the first limit inferior temperature in the first low several years of limes superiors temperature, just make refrigerating generator out of service.Like this, refrigerating generator sends the time of strong correspondingly running noises and refrigerating generator is out of service and refrigerating appliance does not produce noise or time that may produce on a small scale noise replaces mutually in service and refrigerating appliance.
Because the running status of refrigerating generator is only with to account for leading temperature in refrigerating appliance relevant, the in the situation that of traditional refrigerating appliance, user can not directly affect noise emission at large, and, if refrigerating generator enters operation near user rests on refrigerating appliance time, user almost can not do other thing except standing associated noise emission.Although user also can turn-off this utensil, if connect again this utensil when he forgets around he leaves this utensil, he must consider the thing corruption in utensil so, thereby this replacement scheme is feasible hardly.
Task of the present invention is, eliminates described shortcoming.
This task is solved, its mode is, at refrigerating appliance, especially in Domestic refrigerator, it has storage chamber, make the cooling refrigerating generator of this storage chamber, be used for temperature sensor and the control module of the temperature of this storage chamber of sensing, this control module is provided for, in temperature-constant operation pattern, in the time of the first limes superiors temperature higher than in described storage chamber, described refrigerating generator is put into operation, described control module can temporarily be transformed in an operational mode, in described operational mode, even the operation of described refrigerating generator is also blocked higher than described the first limes superiors temperature in the situation that, and, because described refrigerating generator does not move, this operational mode is being known as low noise operational mode below.The operation of blocking described refrigerating generator causes interrupting the cooling of described storage chamber, but as long as described low noise operational mode only temporarily works and described refrigerating appliance automatically returns in temperature-constant operation pattern, this interruption can be allowed to.
In the simplest situation, described control module can comprise user interface, can input one for being transformed into the request of described low noise operational mode by user by this user interface, thereby in the time that user feels to be disturbed due to the noise emission of refrigerating appliance, he can have immediate effect and reduce this noise emission.
Alternatively or addedly, described control module comprises timer, this timer is provided for, and reports that one for being transformed into the request of described low noise operational mode respectively in described timer in the time of the time that be programmed, that periodically repeat if desired with aspect.Meet destination, the time being programmed is respectively and has higher possibility low noise operation is existed to time of demand, for example every day breakfast time, many users in kitchen at next-door neighbour described refrigerating appliance place feed breakfast.
Meet destination, described refrigerating appliance should have user interface, and by this user interface, user can programme to described timer according to its demand oneself.At this, can be for inputting the identical user interface of user interface of the request that user reduces instant noise with user by it.
Described control module can be provided for, and is converted back to temperature-constant operation pattern respectively after the stand-by period given in advance from low noise operational mode.But preferred alternative hereto, that is, be always converted back in described temperature-constant operation pattern in the time that the temperature in described storage chamber reaches than high the second limes superiors temperature of described the first limes superiors temperature.Like this, can avoid because too high temperature jeopardizes the cooling thing being included in described storage chamber, if if described low noise operational mode maintains too for a long time at higher temperature or at the door of storage chamber described in low noise mode for a long time in opening wide or pack into the cooling thing of large calorimetric, described too high temperature for example may produce.
Although described control module can be provided for, unconditionally fulfil the request for being transformed into low noise operational mode, no matter this request is to send by user or by timer, but the concept of request means, different from order, its recipient also may refuse it in some cases.Within the scope of the invention, this decision freedom is also favourable, like this, described control module should preferably be provided for, when the temperature in described storage chamber is during higher than and three limes superiors temperature that can with second limes superiors temperature equate higher than the first limes superiors temperature, ignore the request for being transformed into low noise operational mode.In other words, can cause storage chamber superheated if deferred to, described control module can maintain temperature-constant operation pattern on the contrary with sent request.
If described control module is ignored this request to low noise operation, described user interface should be provided for, and shows a report, and this report is reported user with aspect: described request is left in the basket.Show that such report is significant, and do not depend on, this request is still sent by timer by user oneself, because if user hears the running noises of this refrigerating generator in the time that he does not expect the time point of running noises, show that report makes user can examine the correct running of refrigerating appliance.
In addition, described control module can be provided for, in the time that quick refrigerating mode works, ignore the request for being transformed into low noise operational mode, because can not meet on the one hand to cooling fast request and the request to low noise operation on the other hand simultaneously.In this case; described control module meets destination and gives quick refrigerating mode by priority; because if refrigerating mode works fast, it is that essential and associated temporary transient noise produces and can be allowed by user for the cooling thing of protection conventionally.If user disagrees with this adjusting, can give the possibility that he turn-offs again quick refrigerating mode and selects subsequently low noise operational mode.
As mentioned above, in traditional refrigerating appliance, in the time of the first limit inferior temperature lower than storage chamber, the common controlled unit of refrigerating generator is placed in out of service.Meet further developing of object according to of the present invention, described control module also can temporarily be transformed in pre-cooled operational mode, in this pre-cooled operational mode, even if also maintain the operation of described refrigerating generator when lower than described the first limit inferior temperature.By making described refrigerating appliance move a period of time in described pre-cooled operational mode before being transitioned in described low noise operational mode, with respect to temperature-constant operation pattern, temperature in storage chamber can be lowered, thereby can extend the time period that described low noise operational mode can maintain therein, and the superheated of storage chamber does not occur.
Comfortable for user, in the time that pre-cooled operational mode stops, control module is automatically transformed in low noise operational mode.
Especially can be with acting on the criterion that stops pre-cooled operational mode lower than the second limit inferior temperature lower than described the first limit inferior temperature.
Other features and advantages of the present invention are learnt with reference to drawings clear according to the following description of embodiment.Also learnt the NM feature in the claims of embodiment by these descriptions and accompanying drawing.These features also can occur with the form different with disclosed especially combination here.Therefore the fact that, multiple such features are mentioned in identical sentence or with other context correlation does not draw such conclusion: these features only can occur with disclosed especially combination; Replace, think in principle, functionally do not have problems as long as of the present invention, in multiple such features, also can remove or slightly change indivedual features.Accompanying drawing illustrates:

The flow chart further developing of the program that Fig. 8 carries out in the control module of this refrigerating appliance;
Fig. 1 is the indicative icon of refrigerating appliance, especially family expenses refrigerator or family expenses refrigeration appliance, on this refrigerating appliance, can apply the present invention.This refrigerating appliance comprise one or also comprise multiple that surround by heat insulation housing 1, for the storage chamber 2 of cooling thing and for making the cooling refrigerating generator of this storage chamber 2, this refrigerating generator comprises in known manner: for the compressor 3 of cold-producing medium; Condenser 4, in this condenser, by compressor 3 thermal insulation the cold-producing medium that compresses heat is discharged in environment and in this condensation; And evaporimeter 5, in this evaporimeter, the cold-producing medium of condensation heat absorption situation decline low-pressure and sucked by compressor 3 at the refrigerant vapour of this generation.Here, due to simplicity, evaporimeter 5 is expressed as back wall formula evaporimeter, but self-evident, and the present invention also can apply evaporimeter type arbitrarily, especially also can apply evaporator without frost.
Compressor 3 can be known type arbitrarily; The most frequently used is the piston compressor having by electric motor driven piston.In the time that compressor 3 moves, piston, motor and between compressor 3, condenser 4 and evaporimeter 5 mobile cold-producing medium produce can be in the outside of refrigerating appliance the perceived noise arriving.In the situation that compressor 3 is turned off, this noise source disappears, and the vapour bubble that may sometimes raise in the liquid refrigerant of evaporimeter 5 can also cause the noise that can hear in outside.
Control module 6 on the one hand according to the measured temperature of the temperature sensor 7 on storage chamber 2 and the predefined parameter that can input in user interface 8 according to user on the other hand control the operation of compressor 3.
As illustrate schematicallyd in Fig. 1, user interface 8 comprises display element, for example liquid crystal display 9 of alphanumeric and/or figure, and multiple configuration is to the button 10 of display element 9.For better clarity, here and in following figure, button 10 separates and illustrates with display element 9 respectively, but self-evident, to tactiosensible display element in the situation that, described button also can self be made up of the region of the display plane of display element.
Fig. 2 illustrates the working method of control module 6 intuitively according to flow chart.As long as do not arrange in addition via user, this refrigerating appliance is in temperature-constant operation pattern, and this temperature-constant operation pattern comprises the step S1 to S5 of Fig. 2.Step S1 to S5 repeats circulatingly, thereby completely at random selects a beginning step as described program in these steps.In step S1, control module 6 relatively storage chambers 2 by the measured temperature T of temperature sensor 7 and the first limes superiors temperature T + 1.When higher than this limiting temperature T + 1time, connect compressor (S2), thereby temperature T declines again.In step S3, C.T T and the first limit inferior temperature T -1, and, when lower than this limiting temperature, turn-off again compressor 3(S4).In described limiting temperature one, T + 1or T -1, can in user interface 8, regulate by user; Generality ground, the difference between described limiting temperature is by given in advance regularly.With regard to this respect, described program is carried out conventional thermostatic control corresponding to the temperature in storage chamber 2.
In step S5, whether inspection there is the request of the low noise operation to refrigerating appliance, and wherein, as also explained more accurately below, such request can either also can be sent by the timer of the part that forms control module 6 by user.If there is such request, in step S6, check temperature T whether higher than than the first limiting temperature T + 1the second high limes superiors temperature T + 2.Conventionally, if long temporally in temperature-constant operation pattern before refrigerating appliance, be not this situation, thereby described program branches would be to step S7.Under special condition, for example when refrigerating appliance before the shorter time just in low noise operational mode, or when the door due to storage chamber 2 is for a long time in opening or the temperature of storage chamber 2 being raise exceed T owing to having loaded cooling thing a large amount of, heat before between only temporary transient + 2, program directly turns back to step S1 and therefore ignores the request that low noise moves.
Along with being branched off into S7, refrigerating appliance is transitioned in low noise operational mode.Here, first inspection whether higher than than T + 2the 3rd higher limes superiors temperature T + 3.Select like this T + 3, make temporarily to reach the infringement that this temperature is not worth mentioning for the keeping quality of the cooling thing in storage chamber 2, and no longer can get rid of such infringement also higher temperature is next.T + 3can be for example about 14 DEG C, and T + 1typically+5 DEG C and+select in scope between 10 DEG C.
For the flexible program of a simplification, also can save step S6, and alternatively, described program is directly jumped to step S7 from step S5.Such simplification means limiting temperature T + 2and T + 3unanimously.
When temperature T in step S7 is in T + 3under time (if directly implemented before this step S6, always this situation), turn-off compressor 3(S8), as long as this compressor does not turn-off, and repeating step S7 so for a long time, S8, until the temperature T of storage chamber 2 rises to T + 3.Then, described program automatically turns back to the step S1 of temperature-constant operation pattern.
The zoomed-in view of the user interface that Fig. 3 illustrates the button 10 that has display element 9 and attach troops to a unit under a kind of state, under this state, user interface 8 is ready to accept user's the request in low noise operational mode that is transitioned into.State lattice 11 with " noiseless " mark illustrate to user: the input that user can carry out at present on button 10 is relevant with the low noise operational mode that is for example called simplifiedly in other words " noiseless ".In this state, here altogether in six press keys 10 only those buttons on the left side of display element 9 be assigned with function, described function by the symbol 12,13 and 14 that is adjacent to be illustrated at display element 9 with related button 10 respectively to instruction manual.The middle section of display element 9 is for showing to user the information making an explanation.Arrow 12 is to instruction manual, and adjacent button 10 is for leaving shown menu and for turning back to Previous Menu.The sky circle 13 of " opening " word side shows to user the noiseless operational mode in other words that can select reducing noise by adjacent button 10 on the one hand, and this operational mode is current chosen.Replace, the full circle for symbol 14(adjacent to " pass " word) can recognize, the operational mode of reducing noise is what turn-off.
If user operation adjacent to the button 10 of symbol 13, this impel control module 6 in the program of Fig. 2 to S6 branch.When the inspection of step S6 draws, can make low noise operational mode work, as seen in Figure 4 time, symbol 13 becomes full circle and symbol 14 becomes empty circle, and in the middle section of display element 9 at symbol 13, there is direction board 15 in 14 side, this direction board is determined that low noise operational mode works and indicates to user to user, carrying out to returning automatically of temperature-constant operation pattern simultaneously.User can confirm that (quittieren) is to the knowing of this information by the bottom button 10 on the right side of operation user interface 8, and this causes, and direction board 15 disappears again.The change of operational mode keeps identifying due to the exchange of the form of expression of symbol 13,14.
When the inspection of step S6 draws, can not be transitioned in low noise operational mode time, this fact is also by direction board 16(as shown in FIG. 5) inform user, and with respect to Fig. 3, symbol 13,14 remains unchanged.
According to the configuration further developing of the present invention, Fig. 6 illustrate in the similar state of Fig. 3 in the view of user interface 8.In this configuration situation, except connecting the pattern of reducing noise and turn-off these patterns by the button 10 adjacent to symbol 14 by the button 10 adjacent to symbol 13, also can also select by symbol 17 automatically, the time that is subject to controls and changes.If select conversion automatically,, by give the possibility of user's start time point given in advance at the menu shown in Fig. 7, should start respectively the operation of described reducing noise on described start time point.By means of two intermediary button 10 on the both sides of display element 9, user can select Zhou Tian, and at this Zhou Tian, user wants the pattern of the reducing noise given in advance time started used.In the diagram of Fig. 7, select Thursday, for example can be by finding out in the display mode different from all the other week skies.By means of the button 10 of the left side of display element 9 and the foot on the right, user can increase or reduce the hour, starts low noise operational mode at selected Zhou Tianying during at this hour.The selected hour realizes over sky by operation OK button or by selected another week really surely by this way.When user successfully elite go out at least one week day and at least one hour, the timer of control module 6 generates a conversion request during at the selected hour at every turn at appointed Zhou Tian, and this conversion request makes step S5 that control module 6 can be from Fig. 2 to step S6 branch.
If the time of the low noise of prior known request refrigerating appliance operation, exists prolongation low noise to move the possibility of the time period that can maintain, its mode is, before low noise operation starts, storage chamber to be cooled down consumingly than general case.
Fig. 8 is the flow chart of the working procedure further developing of control module 6, such pre-cooled of this working procedure support.The step S1 to S8 of this program and identical and not explanation again in the flow chart of Fig. 2.If confirm that in step 5 low noise operation (going back) is not requested,, in this program, in step S9, then whether inspection needs pre-cooled storage chamber 2.If not this situation, program turns back to step S1.Need pre-cooled really approve with in step S9 based on being operated the button 10 of user interface 8 by user or the signal based on timer carries out.At this, user class is similar to and comes the time started programming for pre-cooled optional with reference to the illustrated way of figure 7; More properly, can meet destination and arrange, timer produces a signal, and this signal is for requiring the set time spacing before the beginning being programmed of low noise operation pre-cooled.
Control module 6 is pre-cooledly reacted to determining by connecting compressor (S10).Compressor keep so for a long time connect, until in step S11 or definite temperature T drop to than the limit inferior temperature T in temperature-constant operation pattern -1the second low limiting temperature T -2, or definite reaching for being transformed into time point low noise operational mode, that be programmed.Once meet in these conditions, described program branches is to step S6.
