[control to the humidity of hothouse]

The controller being arranged in operation substrate 400 is specifically described below to the wet of hothouse 104 The control of degree.Controller is by controlling the opening and closing (opening/closing time) of hothouse baffle plate 122 and adding The heat time of hot device 124 controls the temperature and humidity of hothouse 104.As long as control is dry The opening and closing of dry room baffle plate 122 and the heating of heater 124, can there is different control moulds Formula.In addition, in the present invention, the only opening and closing of explanation control hothouse baffle plate 122, i.e. drying Room baffle plate 122 is only controlled so as to open or close, but actual primary drying chamber's baffle plate 122 also can It is controlled so as to open air output of the different angles to adjust the cold air being sent in hothouse 104. For the angle that refrigerating chamber baffle plate and temperature-changing chamber baffle plate can similarly be opened by control, omit herein Explanation.

Hereinafter illustrate to the humid control in hothouse 104.

1. it is used to control the parameter of humidity

As described above, controller be based on temperature sensor and humidity sensor send temperature, Humidity data and the humidity gear information of setting are come to the humid control of hothouse 104.Here, setting The temperature in hothouse that temperature sensor is measured is SD_TEMP, if what humidity sensor was measured Humidity in hothouse is SD_HUM.

In addition, the humidity decision content set according to humidity gear information, is set to humidity value S1.Enter One step ground, it is also possible to humidity decision content is set to by a scope according to humidity gear information, for example The higher limit S11 of the hothouse humidity and lower limit S12 of hothouse humidity is set to, is met S11>The relation of S12.

The value of the setting humidity of different gears corresponding different S1, S11 and S12, each gear The value correspondence storage of corresponding S1, S11, S12 in the controller, sets according to different gears It is fixed to be controlled transferring corresponding S1 or S11, S12.In the example of above-mentioned low humidity shelves, S1 is that 30%, S11 is that 25%, S12 is 35%.

More than S1, S11, S12 be the control that the humidity in hothouse 104 is controlled in the present invention Parameter.

In addition, heater 124 can carry out work in the way of intermittent running.By heater 124 The time of the stopping between two tasks is set as that TM, i.e. heater 124 can be every TM's Time carrys out discontinuous operation.

2. basic control scheme

The basic scheme of the humidity of the explanation control hothouse of reference picture 11.As shown in figure 11, when Start in the step S101 after control, judge that the hothouse for detecting is wet in step s 102 Whether degree SD_HUM is more than hothouse humidity decision content S1.If it is judged that be "No", When drying indoor humidity and not having excessive, into step S103, controller makes hothouse baffle plate 122 (SD baffle plates being shown as in figure, similarly hereinafter) closes and makes heater 124 (be shown as SD in figure to heat Device, similarly hereinafter) carrying out discontinuous operation every the time of TM, can so ensure to do for a long time Humidity in dry room 104 is not raised.If it is judged that being "Yes", that is, dry indoor humidity , it is necessary to reduce the humidity in hothouse when excessive, now into step S104, controller makes to do Dry room baffle plate 122 is opened and heater 124 is carried out discontinuous operation every the time of TM, thus To reduce the humidity in hothouse and keep the temperature in hothouse to stablize relatively.

In above-mentioned basic control scheme, the humidity in hothouse is adjusted according to humidity decision content, Can substantially maintain hothouse in temperature on the premise of by the humid control in hothouse wet Near degree decision content.But, when will work as humidity close to humidity decision content S1, it is susceptible to drying The humidity of interior meets the situation that needs are adjusted again quickly after the condition that need not be adjusted, and causes drying Room baffle plate and heater are continually acted.Therefore, present invention additionally comprises following improvement controlling parties Case.

3. control program I is improved

The improvement control program I of the humidity of the explanation control hothouse of reference picture 12.The improvement is controlled Scheme I is to replace with top limit value of humidity and humidity the humidity decision content in basic control scheme Limit value carries out the scheme of humid control.

As shown in figure 12, after control is started in step s 201, sentence in step S202 Whether the disconnected hothouse humidity SD_HUM for detecting is more than hothouse top limit value of humidity S11.Such as Fruit judged result is "No", that is, when drying indoor humidity and there is no excessive, into step S203, Determine whether the hothouse humidity SD_HUM for detecting whether less than humidity lower limit S12. The relation for detecting humidity and top limit value of humidity S11 and lower limit S12 simultaneously is in order to by humidity control System is wet as controlling using the humidity range of S11 to S12 between S11 to S12 The benchmark of degree, it is to avoid hothouse baffle plate and heater are continually acted.If sentenced in step S203 Disconnected result is "Yes", that is, the humidity for detecting is less than humidity lower limit S12, then need to increase Humidity, hence into step S204, closes hothouse baffle plate 122 and makes heater 124 every Carry out discontinuous operation every the time of TM.It is then back to step S201 and starts again at control.If worked as The result judged in step S203 is "No", it is meant that humidity is in top limit value of humidity S11 In the range of the target humidity between lower limit S12, any operation is not carried out, that is, maintain bar Part control action before changing, is then back to step S201 and starts again at control.

On the other hand, the result for judging in step S202 is "Yes", that is, dry indoor humidity mistake , it is necessary to reduce the humidity in hothouse, now into step S205, controller makes drying when big Room baffle plate 122 is opened and heater 124 is carried out discontinuous operation every the time of TM.Then return Return step S201 and start again at control.

In above-mentioned improvement control program I, the humidity in hothouse is adjusted according to humidity range, So that having one section of humidity range as buffering during regulation humidity, it is to avoid hothouse baffle plate and heater The problem continually acted because humidity frequently changes near a point value.

Below explanation makes to be maintained in hothouse 104 humid control within the scope of suitable temperature. On the whole, because the actually humidity of hothouse 104 can be tuned into the refrigeration less than usual humidity Room, so first having to ensure the characteristic that it is used to refrigerate.

4. it is used to control the parameter of temperature

As described above, the temperature, data and the setting that are sent based on temperature sensor of controller Temperature information comes to the cool-down dehumidification of hothouse 104 or heating.Here, setting temperature sensor survey The temperature in hothouse for obtaining is SD_TEMP.

Because hothouse is actually that humidity can be tuned into refrigerating chamber less than usual humidity, so its Temperature has higher limit and lower limit, here, set the temperature upper limit of hothouse 104 as T11, under Limit value is T22, meets T11>The relation of T12.Temperature range between T11 and T22 be Control the scope (0 DEG C to 8 DEG C) of the regulation of explanation in the basic thought of temperature and humidity.Additionally, In order to precisely control the temperature in hothouse, higher limit T11 can also be set to the upper limit Temperature section, will higher limit T11 replace with ceiling temperature section T11 to T12, meet T11>T12 Relation, such as T11 can be 8 DEG C, T12 can be 6 DEG C.Similarly, can also be by under Limit value T22 be set to lower limit temperature section, will lower limit T22 replace with lower limit temperature section T21 To T22, T21 is met>The relation of T22, such as T21 can be 2 DEG C, and T22 can be 0 DEG C.

More than T11, T12, T21, T22, be that the temperature in hothouse 104 is controlled in the present invention The control parameter of degree, with reference to S1, S11, S12 of preceding description humid control parameter come to Humid control within the scope of suitable temperature is illustrated.

In addition, heater 124 can carry out work in the way of intermittent running.By heater 124 The time of the stopping between two tasks is set as that TM, i.e. heater 124 can be every TM's Time carrys out discontinuous operation.

5. the basic thought of control program II is improved

Figure 13 represents the basic thought of the temperature and humidity in control hothouse 104.

As shown in figure 13, when control is proceeded by, the temperature in hothouse 104 is first determined whether Whether in the scope (being suitable to the temperature range of refrigeration) of regulation.If temperature it is too high without In the range of regulation, then preferentially temperature is turned down until temperature is reached in the range of regulation.Turn down The main method of temperature for open hothouse baffle plate 122 and to sending into cold air in hothouse 104. If temperature is too low advised until temperature is reached without within the limits prescribed, preferentially heightening temperature In fixed scope.The main method of temperature is heightened to make heater 124 work.

If temperature is within the limits prescribed, the humidity that humidity regulation is set into user.

Due to the refrigerating chamber characteristic of hothouse 104, thus temperature in hothouse 104 0 DEG C with Upper and temperature in regulation, such as less than 8 DEG C.That is, in this manual by 0 DEG C to 8 DEG C work It is the prescribed limit of the temperature of hothouse 104.Because the temperature in hothouse 104 reaches less than 0 DEG C Shi Chengwei freezing states, so needing to prevent the temperature in hothouse 104 less than refrigerated storage temperature 0 DEG C of lower limit, and temperature only slight beyond refrigerated storage temperature 8 DEG C of the upper limit to being stored in hothouse 104 Dry influence it is little, be typically not more than such as 8 DEG C as the upper limit of refrigerated storage temperature.

In addition, the control to temperature and humidity is carried out always, i.e. as long as setting humidity Gear, then the control of the humidity corresponding to the gear based on the setting is circulated always is carried out.

Based on the basic thought of above-mentioned control temperature and humidity, the present invention have various control temperature and The scheme of humidity.

6. control program III is improved

Be frequently necessary in practice adjust hothouse in temperature, institute as improve control program III, By temperature adjustment into the regulation that humidity is carried out after suitable temperature.

The improvement control program III of the temperature and humidity of the explanation control hothouse of reference picture 14.

As shown in figure 14, after control is started in step S301, first in step S302 It is middle to judge that what is detected dries room temperature SD_TEMP.Judge to dry room temperature herein Whether SD_TEMP is more than the lower limit T21 of lower limit temperature section.The purpose for the arrangement is that preventing from doing Dry indoor temperature is too low, and the temperature in hothouse takes measure described later to rise high level cadre when too low Dry indoor temperature.If the judged result in step S302 is "Yes", that is, dry room temperature Higher than lower limit temperature section lower limit T21 rather than too low temperature, then carry out the control of humidity.

In step s 302, if it is judged that being "No", that is, dry room temperature and be not higher than down The higher limit T21 of temperature section is limited, is then then dried room temperature because temperature is possible to too low The comparing (step S306) of the SD_TEMP and lower limit T22 of lower limit temperature section, to confirm to do Whether dry indoor temperature is less than the lower limit of lower limit temperature section.If temperature is not less than lower limit T22 ("No" in step S306), represents that the temperature in hothouse is not in too low shape State, so that directly return to step S301 carries out the epidemic disaster control of a new round.If temperature is low In temperature upper limit value T22 ("Yes" in step S306), represent that the temperature in hothouse is too low, So needing to increase the temperature in hothouse.The measure taken herein is the closing in step S307 Hothouse baffle plate 122 (not importing cold air) simultaneously makes the continuous firing of heater 124 (heating). Step S301 is again returned to after heating after a while carries out the epidemic disaster control of a new round.

As shown in figure 14, judged result in step s 302 is carried out in the case of being "Yes" " humid control "." humid control " herein can be led to as above-mentioned basic control scheme Cross humid control, or improve control program as described above that the upper limit value and lower limit value of humidity carries out I humidity range for being limited by top limit value of humidity and humidity lower limit like that carries out humidity control System.That is, " humid control " that is shown in Figure 14 could alternatively be shown in Figure 11 Humid control shown in humid control or Figure 12.

It is described above temperature adjustment according to lower limit temperature section (T21 to T22) to suitable warm After degree, humidity is controlled.Control to temperature also can be based on ceiling temperature section (T11 To T12) carry out.Further, since hothouse be refrigerating chamber rather than refrigerating chamber, so to temperature Lower limit (lower limit temperature scope) is sensitive, but even if the temperature in hothouse is only slight beyond temperature Degree higher limit (ceiling temperature scope) also will not have big influence to being stored at dry in hothouse, It is advantageous to the temperature in temperature upper limit value (lower limit temperature scope) control hothouse.

According to above-mentioned improvement control program III, can be by the temperature adjustment in hothouse into suitable Temperature, base carries out the regulation of humidity on the basis of this, by humidity regulation to suitable humidity range. Compared with above-mentioned basic control scheme, humidity is controlled on the basis of humidity range so that regulation is wet There is one section of humidity range when spending as buffering, it is to avoid hothouse baffle plate and heater are because humidity is one The problem for frequently changing near individual point value and continually acting.With the above-mentioned phase of improvement control program I Preferential regulation temperature in the case of too low than, temperature in hothouse, it is ensured that hothouse it is cold Characteristic is hidden, with the effect for preventing the temperature in hothouse too low, and can be by humid control In the range of target humidity.

7. control program IV is improved

It is that temperature is controlled according to lower limit temperature section to improve control program III, according to humidity model Enclose the control program that section is controlled to humidity.But the present invention also can be simultaneously according to upper limit temperature Degree section and lower limit temperature section are controlled to temperature, and humidity is controlled according to humidity range, To perform more precise control.Such control parameter improved used in control program IV has Ceiling temperature section higher limit T11, ceiling temperature section lower limit T12, lower limit temperature section it is upper Lower limit T22, the humidity decision content S1 or top limit value of humidity S11 of limit value T21, lower limit temperature section With humidity lower limit S12.

Referring to the improvement control program IV of the temperature and humidity of Figure 15 explanation control hothouses.

As shown in figure 15, after control is started in step S401, first in step S402 It is middle to judge that what is detected dries room temperature SD_TEMP.Judge to dry room temperature herein Whether SD_TEMP is more than the higher limit T21 of lower limit temperature section.By judging whether temperature is more than One median, can quickly judge whether temperature is too high or too low.If step S402 In judged result be "Yes", that is, dry room temperature higher than lower limit temperature section higher limit T21, Then judge to dry lower limit T12 (step S405) whether room temperature is less than ceiling temperature section again. Do so can carry out humidity tune when temperature is in (between T21 and T12) in optimized scope Section, and preferentially enter the regulation of trip temperature when temperature is not in optimized scope.In step S405 In judged result be "Yes", that is, dry room temperature less than T12 when, illustrate in now hothouse Temperature be in optimized scope in, can further control humidity.

In step S402, if it is judged that being "No", that is, room temperature not higher than T21 is dried, Then room temperature SD_TEMP and lower limit temperature are then dried because temperature is possible to too low The comparing (step S403) of the lower limit T22 of section, to confirm whether the temperature in hothouse is low In the lower limit of lower limit temperature section.If temperature is not less than T22 ("No" in step S403), Represent that the temperature in hothouse is not in too low state, so that directly return to step S401 enters The epidemic disaster control of a row new round.If temperature is less than temperature upper limit T1 (step S403 In "Yes"), represent hothouse in temperature it is too low, so need increase hothouse in temperature Degree.The measure taken herein is that the closing hothouse baffle plate 122 in step S404 (is not imported cold Gas) and heater 124 is worked.Step S401 is again returned to after through heating after a while Carry out the epidemic disaster control of a new round.

In step S405, if it is judged that being "No", that is, dry room temperature and be not less than T12, Then room temperature SD_TEMP and ceiling temperature are then dried because temperature is possible to too high The comparing (step S406) of the higher limit T11 of section, to confirm whether the temperature in hothouse is high In the higher limit of ceiling temperature section.If temperature is not higher than T11 ("No" in step S406), Represent that the temperature in hothouse is not in too high state, so that return to step S405 enters again Trip temperature compares with the size of T12.If temperature is higher than T11 ("Yes" in step S406), Represent that the temperature in hothouse is too high, so needing to reduce the temperature in hothouse.Take herein Measure be opening hothouse baffle plate 122 (importing cold air) in step S407 and make heater 124 stop.Return to step S405 re-starts temperature after through importing cold air after a while Compare with the size of T12.

As shown in figure 15, the judged result in step S405 is carried out in the case of being "Yes" " humid control "." humid control " herein can be led to as above-mentioned basic control scheme Cross humid control, or improve control program as described above that the upper limit value and lower limit value of humidity carries out I humidity range for being limited by top limit value of humidity and humidity lower limit like that carries out humidity control System.That is, " humid control " that is shown in Figure 15 could alternatively be shown in Figure 11 Humid control shown in humid control or Figure 12.

It is described above improvement control program IV according to upper and lower limit temperature section (T11 to T12 and T21 to T22) by temperature adjustment to suitable temperature after, according to humidity upper limit value and lower limit value (S11 And S12) humidity is controlled.Thereby, it is possible to accurately by the temperature adjustment in hothouse into Suitable temperature, carries out the regulation of accurate humidity on this basis.With other above-mentioned controls Scheme is compared, and temperature is controlled on the basis of the temperature section of upper and lower limit and is with humidity upper and lower limit Benchmark controls humidity so that have one section of epidemic disaster scope as buffering during regulation epidemic disaster, Avoid hothouse baffle plate and heater because epidemic disaster near a point value frequently change and it is frequent The problem of ground action.Also, preferentially adjusted in the case that the temperature in hothouse is too low or too high Section temperature, it is ensured that the refrigeration characteristic of hothouse, with preventing the temperature in hothouse too low or mistake Effect high.On this basis, accurately by humid control in the range of target humidity.

It is described above and uses control parameter T11, T12, T21, T22, S1, S11, S12 To control the various schemes of the temperature and humidity in hothouse 104, but the invention is not restricted to above-mentioned The scheme of explanation, for example, can also control temperature according to ceiling temperature section and humidity range parameter And humidity, as long as various parameters are combined to control the scheme of temperature and humidity of the invention In the range of.Carrying out the objective of temperature and humidity control is, according to ceiling temperature section or lower limit temperature Section or both enters the control of trip temperature, during by temperature control in the moderate scope of regulation according to Humidity decision content or humidity upper limit value and lower limit value carry out the control of humidity.In addition, parameter of the invention Above mentioned parameter is also not necessarily limited to, new temperature can also be defined within the temperature range of hothouse Degree section, defines new humidity section in humidity range.

Refrigerator of the invention, can provide independent air-supply path for hothouse so that dry Dry room is not influenceed by outside humidity.Also, by the opening and closing for intelligently controlling hothouse baffle plate With the work of auxiliary heater, by the humidity regulation in hothouse into setting gear it is corresponding Humidity, enables to hothouse to be suitable to preserve different types of dry.Additionally, of the invention dry Dry room is the structure that the hothouse lid with roller is combined with hothouse box body, be ensure that dry Seal needed for dry room, is further ensured that the accuracy for drying indoor humidity.

The concrete structure for being explained above refrigerator of the invention and the humidity, the temperature that are dried interior The step of degree control, method, but the invention is not restricted to described above.In spirit of the invention Various changes can be carried out, the invention obtained after change is within.
