The specific embodiment
The glass door that removing dew on glass device of the present invention for example can be used for refrigerating equipment removes dew.
Show the first embodiment schematic diagram of removing dew on glass device of the present invention as Fig. 1, comprise temperature detecting unit 1, control module 3 and remove and reveal unit 4.Wherein:
Removing dew unit 4 is used for the extexine of glass door is removed dew, can be by heater attached to the glass door extexine, as constituting by electric heating film, also can constitute by the air-supply arrangement of wind direction towards the glass door extexine, as fan, perhaps can send the air-supply arrangement of hot blast, as the fan that comprises the electric wire installation of similar hair dryer structure.
In the memory of processing unit 3a storage in advance as shown in Figure 2 the temperature difference and the functional relation of dewfall point.
Coordinates table in the function of Fig. 2 dewfall point and the temperature difference is shown the temperature difference, and dotted line wherein represents that it is the dewfall zone that dewfall is put this dotted line the right.Here explanation is, for the equipment of selling to different regions, for example sell to the south of high humidity and sell to the little north of humidity, this function can be different, can be that a plurality of functions are stored in the equipment, after selling to the location, select a function (for example can be that sales force or technical staff select by the menu that equipment provides) according to local circumstance.
The functional relation of storage can be that the form of continuous function also can be the form (as the discrete function of table style) of discrete function.Processing unit (3a) calculates the dewfall value that correspondence was calculated or found to the temperature difference according to the temperature data value in the outside in the reach in freezer glass door that obtains, to determine that current dewfall value is whether in the dewfall zone, when current dewfall value is positioned at the dewfall zone, be judged as and reach the dewfall point, at this moment transmit control signal to supply control unit 3b, and also send corresponding control information to power control unit 3c, go to control and remove the power that reveals unit 4.
Wherein, be illustrated in figure 3 as the schematic diagram of device second embodiment of removing dew on glass of the present invention, below at describing with Fig. 1 embodiment difference.As shown in Figure 3, the present invention removes to reveal in the device Humidity Detection unit 2 can also be set, and is used to detect the humidity in the glass door outside, can be realized by the humidity sensor that is arranged on the glass door outside.
Accordingly, temperature outside in the glass door that the processing unit 3a of control module 3 not only detects according to temperature detecting unit 1, the glass door outside humidity that also detects according to Humidity Detection unit 2 are determined the dewfall condition jointly, transmit control signal respectively and control information to supply control unit 3b and power control unit 3c when reaching dewfall point.
And, the functional relation of the storage temperature difference, humidity and dewfall point as shown in Figure 3 in advance in the memory of processing unit 3a.Wherein, curve L among Fig. 4 is expressed as the function of dewfall point and the temperature difference and humidity, it on this curve the dewfall zone, when the current dewfall value that calculates on this curve, i.e. representative has reached the dewfall point, be in the dewfall zone, if the current dewfall value that calculates under this curve, then represents not reach the dewfall point.When judging whether dewfall point, processing unit (3a) calculates the temperature difference according to the temperature data value in the outside in the reach in freezer glass door that obtains, and then calculates or find corresponding dewfall value according to the current humidity value that obtains.
Other principles are identical with the embodiment shown in Fig. 1, repeat no more.
Fig. 5 is the removing dew on glass method of corresponding diagram 1 embodiment of the present invention, may further comprise the steps:
Step 51: the temperature data value of gathering the outside in the refrigerating cabinet glass door by temperature sensor 1.
Wherein, can be real-time acquired data values, also can be periodic acquired data values, as per 5 minutes.
Step 54: because when having arrived dewfall point, connect by the supply control unit 3b of control module 3 and to remove the power supply of revealing unit 4, start except that the dew process.Control module 3 and according to the temperature data value sends control information to power control unit 3c as the temperature difference, dewfall point etc., and control removes the power that reveals unit 4.Removing the dew process can be to carry out by the power supply of certain hour.
For example, be during when remove revealing device 4 attached to the electric heating film on the glass door, the power supply that then is switched to electric heating film is heated and is removed dew.When removing dew device 4 is air-supply arrangement, then connects air-supply arrangement and removes dew to the air-supply of glass door extexine.Air-supply arrangement can be by fan, place the heater strip in the air-supply arrangement to constitute, and can send hot blast to accelerate to remove the dew process to the glass door extexine like this.
Fig. 6 is the removing dew on glass method of corresponding diagram 3 embodiment of the present invention, may further comprise the steps:
Step 61: by the humidity data value in the humidity sensor 2 and the temperature sensor 1 collection refrigerating cabinet glass door outside, and the temperature data value outside in the reach in freezer glass door.
Step 64: because when having arrived dewfall point, connect by the supply control unit 3b of control module 3 and to remove the power supply of revealing unit 4, start except that the dew process.Control module 3 and according to the temperature data value sends control information to power control unit 3c as the temperature difference, dewfall point etc., and control removes the power that reveals unit 4.Removing the dew process can be to carry out by the power supply of certain hour.
In addition, the embodiment of the invention is not only applicable to refrigerating cabinet glass door, is applicable to other similar devices yet, such as, devices such as motor-vehicle glass window as long as it has adopted the above-mentioned dew device and method that removes to remove when revealing, also belong to protection scope of the present invention.
