Abstract
The invention provides a kind of control method and dehumidifier of dehumidifier, after start, first start fan operation, enter step of drying in advance; After pre-blowing step completes, dehumidifier judges that whether environmental working condition is eligible, and as met, then start compressor operating, complete machine enters dehumidification operating mode.The control method of dehumidifier of the present invention, dehumidifier such as adopts the combustible refrigerants such as R290, by the control of control program, the first startup optimization of start rear fan, process of drying in advance, rear startup compressor operating.When if the air-conditioning placed long-term or dehumidifier system have a small amount of leakage of refrigerant and be gathered in body, improve the security of complete machine.
Description
Technical field
The invention belongs to dehumidifier control technology field, particularly relate to a kind of control method and dehumidifier of dehumidifier.
Background technology
In prior art, due to freon class cold-producing medium, such as R22 more or less has destruction to environment, and the native compound that some occurring in natures such as R290 exist starts to be considered to be used as a large amount of use now but the substitute closing on superseded cold-producing medium R22.But because R290 has flammable physical characteristic that can be quick-fried, use the securities of native compound to air-conditioner, dehumidifier such as R290 to have higher requirement.
In prior art, the system control model of dehumidifier is, after start, compressor and blower fan start simultaneously, and complete machine brings into operation.If adopt the native compound replacement fluorine Leon class cold-producing mediums such as R290, produce once cold-producing medium and reveal, can not the cold-producing medium of leakage was discharged to outside body before compressor start, there is potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of control method and dehumidifier of dehumidifier, before compressor start, the cold-producing medium of leakage is discharged to outside body, improve the security of dehumidifier.
The present invention is achieved through the following technical solutions:
The control method of dehumidifier, wherein, after start, first starts fan operation, enters step of drying in advance; After pre-blowing step completes, dehumidifier judges that whether environmental working condition is eligible, and as met, then start compressor operating, complete machine enters dehumidification operating mode.
Dehumidifier, comprises above-mentioned dehumidifier control method.
Beneficial effect of the present invention is as follows:
The control method of dehumidifier of the present invention and dehumidifier, dehumidifier such as adopts the combustible refrigerants such as R290, by the control of control program, the first startup optimization of start rear fan, process of drying in advance, rear startup compressor operating.When if the air-conditioning placed long-term or dehumidifier system have a small amount of leakage of refrigerant and be gathered in body, improve the security of complete machine.

Detailed description of the invention
Ask for an interview Fig. 1 to Fig. 3, the invention discloses a kind of control method of dehumidifier, wherein, after start, first start fan operation, enter step of drying in advance; After pre-blowing step completes, dehumidifier judges that whether environmental working condition is eligible, and as met, then start compressor operating, complete machine enters dehumidification operating mode.
As shown in Figure 1, pre-blowing step comprises:
S1: enter pre-blowing wind program entry;
S2: judge whether blower fan is opened; In this way, enter step s3, as no, enter step s4;
S3: judge whether the unlatching timing time t of blower fan is less than the first setting-up time t
if one, as t < t
if one, enter step s5;
S4: the unlatching timing time of blower fan resets;
S5: again judged through 1 second, until the blower fan opening time be more than or equal to t
if one, enter step s6;
S6: enter dehumidification mode program entry.
In described step s2, judge that the concrete grammar whether blower fan is opened is: judge whether blower fan is in low wind shelves or apoplexy shelves or high wind shelves.
Preferably, t
if oneit is 20 seconds.
As shown in Figure 2, dehumidifier judges that environmental working condition concrete grammar that is whether eligible and control dehumidification operating mode is:
1. judge whether ambient humidity is more than or equal to setting humidity, in this way, enter step 2., as no, enter step 3.;
2. environment temperature is judged whether within the scope of design temperature, if in this scope, again judge whether ambient humidity is greater than setting humidity, if ambient humidity is greater than setting humidity, continue to judge whether the blower fan opening time is more than or equal to 20 seconds, if the blower fan opening time is more than or equal to 20 seconds, then, when these three conditions meet simultaneously, enter step 4.; As these three conditions can not meet simultaneously time, enter step 5.;
3. judge whether ambient humidity is less than or equal to setting humidity, in this way, enter step 5.;
4. compressor is run;
5. compressor cuts out.
Preferably, above-mentioned design temperature scope is: 2 ~ 45 DEG C.
Judging in the whether qualified concrete grammar of environmental working condition, the deviate of ambient humidity adopts 5%.
As shown in Figure 3, compressor runs continuously, until when ambient humidity is less than or equal to setting humidity, compressor is out of service, due to the effect of dehumidifier Operation system setting, now blower fan extends operation t again
if twominute.
Preferably, t running time is extended
if twofor: 3 minutes.
Above reason is as follows: before compressor is opened, blower fan opens 20 seconds, and compressor closedown rear fan runs 3 minutes, can prevent leakage of refrigerant, the cold-producing medium of leakage is got rid of loom in time, in order to avoid cause a hidden trouble.
The invention also discloses a kind of dehumidifier, comprise above-mentioned dehumidifier control method.
Above-mentioned listed specific implementation is nonrestrictive, and to one skilled in the art, not departing from the scope of the invention, the various modifications and variations of carrying out, all belong to protection scope of the present invention.
