General common French clamshell doors computer refrigerator can design a vertical beam usually between its two fans cold sotrage door, the existence of this vertical beam can be convenient to the overlap joint and the sealing of the door envelope between the two fan cold sotrage doors.But because the thermal conductivity of thickness of vertical beam own and middle packing material, refrigerator its surface temperature when normal refrigeration is lower, is easy to generate condensation, for preventing its surperficial condensation, can paste a heater at the vertical beam inner surface usually, and its surface temperature is raise.
At present general manufacturer for ease; When design vertical beam heater, adopt constant heating ratio; Because refrigerator environment temperature and humidity in use changes; The dew-point temperature of air is different under different temperature and the damp condition, if adopt constant heating ratio generally can cause waste of energy to a certain degree or can not effectively satisfy the anti-condensation requirement under the different environments for use.
Consider that environment temperature and humidity all are two key factors that influence dew-point temperature; Thereby the manufacturer that has imports its control module as variable with temperature parameter and humidity parameter simultaneously in its product; Exporting a control instruction then comes control heater to carry out work; So that surface temperature is not less than dew-point temperature; Like Chinese utility model patent ZL201120119754.0 a kind of control device of anti-condensation heater strip is disclosed, based on this design concept, for the antifogging function of realizing that it is basic; Then hardware components comprises a humidity sensor, an environment temperature sensor and an anti-condensation surface temperature sensor at least, and whether the precision of these sensors realizes playing crucial effects to the function of anti-condensation.The then essential database that will comprise the humid air parameter of software section equally also must have a series of reliable instructions to judge gathering the data of coming, and exports an instruction at last heater is controlled.The precision of sensor is restricting the reliability of software instruction, thus for realize anti-condensation demand then must be under aspect the software and hardware the very big time, difficulty is more greatly.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.
Shown in Fig. 1 to 3; The utility model discloses the heating control apparatus of the anti-condensation of a kind of clamshell doors refrigerator cold-storage vertical beam; Comprise the heater 1, environment temperature sensor 2 and the control module 3 that are arranged on refrigerator 10 inside columns 20; Said environment temperature sensor 2 outputs signal to control module 3 according to the ambient temperature value that collects, 1 work of control module 3 output signal controlling heaters.Wherein, The power of heater 1 is chosen to be steady state value according to refrigerator volume size and vertical beam size, and when producing refrigerator, heater 1 sticks on vertical beam 20 inner surfaces; Shown in Figure 3; It is effective when heater 1 is worked like this to be heated up in vertical beam 20 surfaces, and environment temperature sensor 2 is located at refrigerator 10 outer surface (not shown), is used for the environment temperature parameter is gathered.Control module 3 is by chip microcontroller, and equipment is simple, and reliability is high.
Referring to Fig. 4, be the flow chart of the utility model control procedure.
At first, carry out the setting of relevant parameter.Anti-condensation applied code according to relevant is set at steady state value with relative humidity, and this steady state value generally is not less than the maximum relative humidity under user's regular service conditions, as 80% or 85%.Heater 1 is stopped heat time heating time T be made as constantly, be generally 1 minute.The ambient temperature range that refrigerator is used is divided into the plurality of temperature interval by 1 ℃ temperature interval, and the desired ambient temperature range of the wideest climate zone that uses of refrigerator is generally 10 ℃ ~ 43 ℃ at present.
Then; The ambient temperature value t0 that environment temperature sensor 2 collects is if within certain temperature range the time; Control module 3 is according to the maximum t ' in this temperature range; And calculate the heating ratio under this temperature conditions according to the calculation procedure that is pre-stored in the single-chip microcomputer, calculate t heat time heating time of final heater through the heat time heating time T of stopping that setting again.
Then, control module 3 is exported to its work of heater control with heater t heat time heating time that calculates.
Illustrate as follows:
As encircle temperature be 24.3 ℃ then between 24 ℃ ~ 25 ℃, control program can be automatically according to also exporting to heater heat time heating time 25 ℃ of heating ratio and heat time heating times (0.5 minute) that calculate corresponding 25 ℃ of temperature conditions under.In like manner, the ring temperature be 31.6 ℃ then between 31 ℃ ~ 32 ℃, control program can be automatically according to also exporting to heater heat time heating time 32 ℃ of heating ratio and the heat time heating times (2 minutes) that calculate corresponding 32 ℃ of temperature conditions under.
Thereby the utility model is experienced different environment temperature control heater 1 different heating ratio under these environment temperatures through environment temperature sensor 2.Optimized heating ratio need satisfy the anti-condensation demand of vertical beam 20 under varying environment temperature and humidity condition, and saves energy to greatest extent.
In the above-mentioned control procedure, relative humidity is set at steady state value, can reduce the complexity of software systems and hardware system greatly; In addition because the dew-point temperature of humid air receives environment temperature (being dry-bulb temperature) and two condition effect of relative humidity; After relative humidity had been confirmed, the dew-point temperature of humid air only changed with the variation of environment temperature, like Fig. 5; Can see from the humid air psychrometric chart to draw under same environmental damp condition that the high more then dew-point temperature of environment temperature is also high more.Also have owing to the indoor temperature fluctuation of refrigerator cold-storage is little; Be set under certain temperature conditions the consumer; As be set under 5 ℃ the situation, the variations in temperature of vertical beam 20 outer surfaces then mainly is the influence that receives environment temperature, what is more important vertical beam surface temperature and environment temperature extent directly determine the possibility of condensation generation simultaneously; Therefore; Can adopt single environment temperature parametric variable to come the heater 1 of anti-condensation is controlled, when reducing cost, simplifying control program, guarantee the stability and the reliability of system.
Fig. 6 is refrigeration vertical beam surface temperature variable condition figure under the varying environment, and among the figure, the A line is the minimum surface temperature that vertical beam does not produce condensation under certain damp condition, and the B line is the dew-point temperature under certain damp condition, and the C line is heaterless vertical beam surface temperature.Can know do not have under the situation of heating at refrigeration vertical beam 20 from figure, environment temperature is high more, and vertical beam surface temperature and environment temperature temperature difference are also big more, and the possibility that produces condensation is big more.So want head it off then to need more heats that replenish to reduce this temperature difference more.And under low temperature environment, both temperature differences are little, and the possibility that produces condensation is also little, and needed heat is also little.In other words along with the increase of environment temperature; When on the vertical beam during no heater the difference of its surface temperature and environment temperature and certain damp condition dew-point temperature down increasing, therefore along with the heating of the rising heater of environment temperature is satisfied and prevented the condensation requirement to remedy both temperature differences (as shown in Figure 7) than the corresponding rising of regular meeting.The heating ratio is meant the heat time heating time of heater and the ratio of heat time heating time and dwell time sum.
Among Fig. 7, along with the increase of environment temperature, the heating ratio of vertical beam upper heater is linear to be increased, and the vertical beam surface temperature is maintained more than the dew-point temperature, satisfies anti-condensation requirement.
But; Even identical heating ratio; It is different to set the different fluctuating ranges of vertical beam surface temperature that also can cause heating cycle; If it is too big that set the excessive vertical beam surface temperature fluctuating range that then can cause heating cycle, the crest temperature is too high can to influence the normal users experience, and the trough temperature is crossed the low condensation that then is easy to generate.In order to make the vertical beam surface temperature maintain within the acceptable temperature range and to be unlikely to make the heater start-stop too frequent; Present embodiment is set at constant with the dwell time T of heater; Generally got 1 minute, then the different heating ratio under the varying environment temperature can meet the demands through controlling different heat time heating times.
As shown in Figure 8, t1 is heater heat time heating time under the low temperature environment; Tx is heater heat time heating time under the hot environment; T is the dwell time that heater is set; The heating ratio of heater increases along with the increase of environment temperature; In the time of working control the heater dwell time under each environment temperature is set at constant time T; Then the heat time heating time of a having heaters (t1, t2, t3 ... Tn) increase with environment temperature increases.
Consider the precision of temperature sensor and the integrity problem of anti-condensation simultaneously; The design temperature precision is made as 1 ℃ in system; Be about to 10 ℃ ~ 43 ℃ temperature intervals of ambient temperature range that refrigerator uses and be divided into a plurality of temperature ranges, each temperature range corresponding heat time heating time by 1 ℃.
The utility model control device be through can effectively satisfying the anti-condensation demand of vertical beam under different service conditions the heat time heating time that the heater of refrigeration vertical beam on anti-regulated in the variation of environment temperature automatically, and saves electric energy for the user to greatest extent.The anti-condensation adaptive ability of the utility model is strong, simple, the realization easily of control device, and be easy to safeguard.The temperature sensor that does not also need simultaneously high-precision humidity sensor and anti-condensation surface, therefore no matter be from hardware or software angle, the cost of the utility model is all very cheap.
