Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
As shown in fig. 1 to 2, the present invention provides a method for controlling the constant temperature of a wine cabinet, comprising:
acquiring the volume L of the wine cabinet 100;
selecting heating power P of the heating wire according to the volume L of the wine cabinet 100;
detecting an ambient temperature Te;
setting a first temperature threshold T1;
detecting the temperature Tr in the wine cabinet 100;
setting a second temperature threshold T2;
when Te is smaller than T1 and Tr is smaller than T2, controlling the heating wire to work;
setting a third temperature threshold T3;
detecting the temperature Th of the heating wire 1;
the operation rate of the heating wire 1 is selected according to the heating wire 1 temperature Th and the third temperature threshold T3.
Thus, when the ambient temperature Te is low and the temperature Tr in the cabinet 100 is low, the heating wire 1 operates; the heating power P of the heating wire 1 is judged according to the volume L of the wine cabinet 100, so that unstable temperature in the wine cabinet 100 caused by too high or too low heating power P of the heating wire 1 is prevented; and, can select the operation rate of heater strip 1 according to heater strip 1 temperature Th and third temperature threshold value T3, also further prevent that the distribution of heater strip operating time from unreasonable leading to the temperature in the gradevin uneven.
The step of selecting the heating power P of the heating wire 1 according to the volume L of the wine cabinet 100 includes:
when L is less than or equal to 100L, the heating power P of the heating wire 1 is selected to be 5W;
when L is more than 100L and less than or equal to 200L, the heating power P of the heating wire 1 is 10W;
when L is more than 200L and less than or equal to 300L, the heating power P of the heating wire 1 is selected to be 20W.
Obviously, if the internal volume L of the wine cabinet 100 is smaller, the heating power P of the heating wire 1 is not required to be too high; if the internal volume L of the wine cabinet 100 is large, the heating power P of the heating wire 1 can be selected to be high. Therefore, the heating power P of the heating wire 1 can be limited according to the volume L of the wine cabinet 100, and the condition that the temperature in the wine cabinet 100 is too high or too low due to too high or too low heating power P of the heating wire 1 is prevented.
Further, the step of selecting the operation rate of the heating wire 1 according to the temperature Th of the heating wire 1 and the third temperature threshold T3 includes:
when Th is less than or equal to T3, the operation rate of the heating wire 1 is selected to be 100%;
when T3 is more than Th and less than or equal to T3+deltat1, the operation rate of the heating wire 1 is selected to be 90%;
when T3+Delta1 is more than Th and less than or equal to T3+Delta2, the operation rate of the heating wire 1 is selected to be 70%;
when T3+Delta2 is less than Th and less than or equal to T3+Delta3, the operation rate of the heating wire 1 is selected to be 50%.
That is, the temperature of the heating wire 1 can be detected by the third temperature sensor 2 near the heating wire 1, and if the temperature of the heating wire 1 is too low, the heating wire 1 is kept in 100% non-stop operation; if the temperature of the heating wire 1 is too high, the heating wire 1 does not need to run for a long time, so that the problem of too high local temperature in the wine cabinet 100 can be prevented, and the temperature in the wine cabinet 100 is ensured to be stable.
Therefore, the operation rate of the heating wire 1 in the invention has four different stages, and the temperature Th of the heating wire 1 obtained by detection is subdivided, so that the operation rate of the heating wire 1 can be gradually adjusted under the condition that the temperature of the heating wire 1 is too high, and the abrupt change of the temperature of the heating wire 1 can be prevented.
The operation rate refers to the duty ratio of the operation time of the heating wire 1 in the total operation time of the wine cabinet 100. For example, when the operation rate is 50%, the working time of the heating wire 1 accounts for 50% of the total operation time of the wine cabinet 100, so that the heating wire 1 can be stopped after working for a period of time, and the local temperature near the heating wire 1 is prevented from being too high.
Further, it is apparent that Δt3 > Δt2 > Δt1in the present embodiment.
In addition, in order to further improve the constant temperature in the wine cabinet 100, the wine cabinet 100 is further provided with the fan 3, and the fan 3 can work after the heating wire 1 is started to blow the wine cabinet 100, so that the temperature in the wine cabinet 100 is relatively even, and the temperature at a certain part in the wine cabinet 100 is further prevented from being too high.
Thus, the step "control the operation of the heating wire 1" comprises, after: the fan 3 is controlled to start.
And, after the step of "controlling the fan 3 to start", it includes:
selecting the operation rate of the fan 3 according to the temperature Th of the heating wire 1;
setting a fourth temperature threshold T4;
if Th is more than or equal to T4, the operation rate of the fan 3 is 80%;
if T4-Deltat 1' is less than or equal to Th < T4, the operation rate of the fan 3 is 60%;
if T4-Deltat2 'is less than or equal to Th and less than T4-Deltat1', the operation rate of the fan 3 is 40%;
if Th is less than T4-Deltat 2', the operation rate of the fan 3 is 30%.
Also, in this step, the temperature Th of the heating wire 1 is detected and compared. Specifically, when the temperature Th of the heating wire 1 is too high, the time for which the blower 3 is operated is also relatively long, and when the temperature Th of the heating wire 1 is low, the time for which the blower 3 is operated is also relatively short.
Therefore, the operation rate of the fan 3 in the invention has four different stages, and the fan 3 is subdivided according to the detected temperature Th of the heating wire 1, so that the operation rate of the fan 3 can be gradually adjusted under the condition that the heating wire 1 is higher, and the abrupt change of the temperature in the wine cabinet 100 can be prevented. In addition, by introducing the operation rate of the fan 3, the temperature average in the wine cabinet 100 can be ensured, and the sudden drop of the temperature in the wine cabinet 100 caused by the fact that the fan 3 still keeps high operation rate under the condition that the temperature of the heating wire 1 is low can be prevented.
Similarly, the operation rate of the fan 3 in the invention also refers to the duty ratio of the operation time length of the fan 3 in the total operation time length of the wine cabinet 100, for example, when the operation rate of the fan 3 is 30%, the operation time length of the fan 3 accounts for 30% in the total operation time length of the wine cabinet 100, so that the fan 3 can be stopped after a period of operation, and heat is prevented from being blown away under the condition that the temperature of the heating wire 1 is not raised higher, and the temperature in the wine cabinet 100 is slowly raised.
Specifically, in the present invention, t4=60 ℃; Δt1' =10 ℃; Δt2=30℃.
If Th is more than or equal to 60 ℃, the operation rate of the fan 3 is 80%;
if Th is more than or equal to 50 and less than 60, the operation rate of the fan 3 is 60%;
if Th is more than or equal to 30 and less than 50, the operation rate of the fan 3 is 40%;
if Th is less than or equal to 30, the operation rate of the fan 3 is 30 percent.
Of course, the object of the present invention can be achieved if T4, [ delta ] T1, [ delta ] T2 ] are other values.
In addition, the wine cabinet constant temperature control method further comprises the following steps:
detecting the continuous heating time period Sl of the heating wire 1;
setting a duration threshold value Sv;
if the Sl is more than or equal to the Sv, controlling the power-off duration Sp of the heating wire 1.
In the present embodiment, sv=48 h and sp=60 min.
That is, when the continuous heating time period S1 of the heating wire 1 exceeds 48 hours, the heating wire 1 is forcibly powered off, preventing the heating wire 1 from being damaged after the heating wire 1 is operated for a long time.
Of course, if the first, second and third temperature sensors 2 are damaged, the heating wire 1 is forced to be powered off.
The invention also provides the wine cabinet 100, wherein the wine cabinet 100 comprises a shell 10 and a heating wire 1 arranged on the inner side of the shell 10; as described above, the wine cabinet 100 further includes a first temperature sensor disposed outside the housing 10 for detecting the ambient temperature Te, a second temperature sensor disposed in the housing 10 and far away from the heating wire 1 for detecting the temperature Tr in the wine cabinet 100, and a third temperature sensor 2 disposed in the housing 10 and near the heating wire 1 for detecting the temperature Th of the heating wire 1. In addition, the box body comprises a backboard, and the heating wire 1 is arranged close to the backboard; the box body further comprises an aluminum foil adhesive tape which is attached to the back plate and at least covers the heating wire 1. The aluminum foil adhesive tape can fully transfer heat generated during the operation of the heating wire 1 into the whole box body, so that the temperature is more uniform.
In summary, the present invention provides a wine cabinet 100 and a constant temperature control method thereof, when the ambient temperature Te is low and the temperature Tr in the wine cabinet 100 is low, the heating wire 1 works; the heating power P of the heating wire 1 is judged according to the volume L of the wine cabinet 100, so that unstable temperature in the wine cabinet 100 caused by too high or too low heating power P of the heating wire 1 is prevented; and, can select the operation rate of heater strip 1 according to heater strip 1 temperature Th and third temperature threshold value T3, also further prevent that the distribution of heater strip operating time from unreasonable leading to the temperature in the gradevin uneven.
