The specific embodiment
Below with reference to accompanying drawing specifically describe according to of the present invention for have prevent and/or control the refrigerator of condensation device and for prevent refrigerator and/or on the method for dewfall.Should be noted that accompanying drawing must not be accurate dimension, and the fineness of lines or the size of parts etc. can be exaggerated with being convenient to explain for clear.In addition, consider function of the present invention and limit term below, and can be according to user or operator's intention, and be changed.Therefore, the definition of term should be explained according to the content in whole description.
As shown in Figure 1, exemplary refrigerator has by the freeze cycle of carrying out with lower member: compressor 20, is suitable for compressed refrigerant; Condenser 30, is suitable for using the cooling cold-producing medium from compressor 20 of the extraneous air air of refrigerator (for example around); And evaporimeter 40, be suitable for by the evaporation cold-producing medium by condenser 30 and carry out the cooling air that (for example, refrigerator is around) exists around it.
In addition, fan 50 is for cold-producing medium being blowed to condenser 30, to reduce by the temperature of the cold-producing medium of condenser 30, and such as heat pipe of pipeline 70() be suitable for generation heat around refrigerator main body 10, thereby prevent in refrigerator main body 10 and/or on dewfall.Pipeline 70 arranges below cover plate 60 or under the outside outer surface of refrigerator, below the strip of paper used for sealing position on fridge exterior face or with it near arranging.
As shown in Figure 2, preventing and/or controlling condensation device in refrigerator can comprise controller 80 according to an embodiment of the invention, is suitable for controlling the operation of refrigerator; And outer moisture sensor and/or detector 90.Humidity sensor and/or detector are suitable for determining the humidity in refrigerator main body 10 state around.
More specifically, outer moisture sensor and/or detector 90 are for measuring the humidity of refrigerator main body 10 ambient airs.Outer moisture sensor and/or detector 90 are positioned at door and cover plate around, in this easy generation dewfall.
With reference to figure 3 explain for prevent refrigerator and/or on the method for dewfall.
In the time powering for refrigerator, as shown in Figure 3, controller 80 is determined the air condition of internal state and refrigerator outside, and each load condition is operated to carry out by proper procedure.
More specifically, refrigerator main body 10 temperature is around detected, checks or determine by external temperature sensor and/or detector (not shown).Refrigerator main body 10 humidity is around by outer moisture sensor and/or detector 90 detects or determine.
External temperature and outer moisture are inputed to controller 80 by external temperature sensor and outer moisture sensor 90.
Because humidity and Current Temperatures are depended in the formation of dew, so external temperature sensor is mounted, lays and/or uses.For example, if refrigerator maintains in the environment of relative steady temperature at extraneous air, can only use outer moisture sensor 90.
As shown in Figure 4, the rotary speed of fan 50 is inversely proportional to respect to the humidity around refrigerator main body 10 and the temperature of pipeline 70.
For example, if outer moisture has the predetermined or set-point that promotes dewfall, the rotary speed of fan 50 is lowered, thereby increases the temperature of pipeline 70.
The example of the rotary speed for controlling fan 50 is described with reference to Fig. 3 below.
If outer moisture is less than 60% with respect to any external temperature, while using the rotary speed of controller 80 fans 50 to be set to nominal load 100% of potential and/or maximum rotative speed.
In the time determining that refrigerator main body 10 humidity is around equal to or greater than the moisture condition that promotes dewfall, the output of fan 50 is maintained at utmost, speed or speed.Even the temperature of pipeline 70 from or reduce in the maximum rotative speed of fan 50, dewfall will not be affected or be involved.
In addition, if in the scope of the outer moisture detecting between 60% and 70%, while using the rotary speed of controller 80 fans 50 to be set to nominal load 80% of rotary speed.If outer moisture is detected as in the scope between 70% and 80%, while using the rotary speed of controller 80 fans 50 to be set to nominal load 60% of rotary speed.In addition, if outer moisture is detected as in the scope between 80% and 90%, while using the rotary speed of controller 80 fans 50 to be set to nominal load 40% of maximum rotative speed, if and outer moisture is detected as in the scope between 90% and 100%, while using the rotary speed of controller 80 fans 50 to be set to nominal load 20% of maximum rotative speed.
Therefore,, in the time that refrigerator main body 10 humidity around increases, in order to prevent dewfall on refrigerator main body 10, according to the moisture condition detecting, the rotary speed of fan 50 is lowered, thereby advantageously improves the temperature of pipeline 70.
Above-mentioned value, all as exemplary proposed, is still not limited to this, according to refrigerator main body 10 moisture condition around, has different control operations, therefore, according to other different moisture levels states, can carry out corresponding control logic.
Because dewfall depends on humidity and temperature, according to embodiments of the invention, the rotary speed of fan 50 is controlled by refrigerator main body 10 moisture condition and state of temperature around.
As mentioned above, according to an embodiment of the invention, have prevent and/or control the refrigerator of condensation device and for prevent refrigerator and/or on the method for dewfall for being set to optimum rotary speed according to the rotary speed of the moisture condition around refrigerator main body 10 and state of temperature fan, so that being maintained, the temperature of pipeline 70 (for example effectively prevents on refrigerator, near strip of paper used for sealing) temperature of dewfall, thus effectively prevent dewfall on the gasket of refrigerator main body or cover plate.
Although described the present invention in conjunction with certain exemplary embodiments, it is not subject to embodiment to limit and be only defined by the following claims.Should be appreciated that, without departing from the spirit and scope of the present invention in the situation that, those skilled in the art can change or revise these embodiment.
