Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 2, the invention provides a constant temperature control method for a wine cabinet, comprising the following steps:
obtaining the volume L of the wine cabinet 100;
selecting the heating power P of the heating wire according to the volume L of the wine cabinet 100;
detecting the 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 less than T1 and Tr is less than T2, the heating wire is controlled to work;
setting a third temperature threshold T3;
detecting the temperature Th of the heating wire 1;
the operating rate of the heating wire 1 is selected on the basis of 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 wine cabinet 100 is low, the heater 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 the unstable temperature in the wine cabinet 100 caused by the overhigh or overlow heating power P of the heating wire 1 is prevented; moreover, the operation rate of the heating wire 1 can be selected according to the temperature Th of the heating wire 1 and the third temperature threshold T3, and the uneven temperature in the wine cabinet caused by the unreasonable distribution of the working time of the heating wire is further prevented.
The step of selecting the heating power P of the heating wire 1 according to the volume L of the wine cabinet 100 comprises the following steps:
when L is less than or equal to 100L, selecting the heating power P of the heating wire 1 as 5W;
when L is more than 100L and less than or equal to 200L, selecting the heating power P of the heating wire 1 as 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 volume L in the wine cabinet 100 is small, the heating power P of the heating wire 1 does not need to be too high; if the volume L in the wine cabinet 100 is large, the heating power P of the heating wire 1 may 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 phenomenon 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 can be prevented.
Further, the step of "selecting the operation rate of the heating wire 1 according to the heating wire 1 temperature Th and the third temperature threshold T3" comprises:
when Th is less than or equal to T3, the operation rate of the heating wire 1 is selected to be 100%;
when the Th is more than T3 and less than or equal to T3+ delta T1, the operation rate of the heating wire 1 is selected to be 90 percent;
when T3+ delta T1 is more than Th and less than or equal to T3+ delta T2, the operation rate of the heating wire 1 is selected to be 70%;
when T3+ delta T2 is more than Th and less than or equal to T3+ delta T3, 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 keeps 100% of non-stop operation; if the temperature of the heating wire 1 is too high, the heating wire 1 does not need to be operated 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 heater strip 1 in the present invention has four different stages, and is subdivided according to the detected temperature Th of the heater strip 1, so that the operation rate of the heater strip 1 can be gradually adjusted even if the temperature of the heater strip 1 is too high, and the temperature of the heater strip 1 can be prevented from suddenly changing.
The operation rate is the ratio of the working time of the heating wire 1 to 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 is stopped after working for a period of time, and the local temperature near the heating wire 1 is prevented from being too high.
Also, it is apparent that Δ t3 > - Δ t2 > - Δ t1 in the present embodiment.
In addition, in the invention, in order to further improve the temperature constancy in the wine cabinet 100, the fan 3 is further arranged on the wine cabinet 100, and the fan 3 can work after the heating wire 1 is turned on to blow air into the wine cabinet 100, so that the temperature in the wine cabinet 100 is relatively even, and the temperature of a certain part in the wine cabinet 100 is further prevented from being too high.
Thus, the step "controlling the operation of the heating wire 1" comprises, after: and controlling the fan 3 to start.
And, after the step "controlling the fan 3 to start", the method 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 Th is less than T4 and is more than or equal to T4-delta T1', the operation rate of the fan 3 is 60 percent;
if Th is less than T4 to delta T1 'and T4 to delta T2' are more than or equal to, the operation rate of the fan 3 is 40 percent;
if Th is less than T4-delta T2', the operation rate of the fan 3 is 30%.
Also, in this step, the temperature Th of the heater wire 1 is detected and compared. Specifically, when the temperature Th of the heater wire 1 is too high, the operation time of the fan 3 is relatively long, and when the temperature Th of the heater wire 1 is low, the operation time of the fan 3 is relatively short.
Therefore, the operation rate of the fan 3 in the invention has four different stages, and is subdivided according to the detected temperature Th of the heating wire 1, and under the condition that the heating wire 1 is higher, the operation rate of the fan 3 can be gradually adjusted, and the temperature in the wine cabinet 100 can be prevented from suddenly changing. Moreover, the running rate of the fan 3 is introduced, so that the average temperature in the wine cabinet 100 can be ensured, and the sudden temperature drop in the wine cabinet 100 caused by the fact that the fan 3 still keeps a high running 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 present invention also refers to a ratio of the operation duration of the fan 3 to the total operation duration of the wine cabinet 100, for example, when the operation rate of the fan 3 is 30%, the operation duration of the fan 3 is 30% of the total operation duration of the wine cabinet 100, so that the fan 3 is stopped after operating for a period of time, and the heat is prevented from being blown away when the temperature of the heating wire 1 is not increased to a high level, which results in a slow temperature increase in the wine cabinet 100.
Specifically, in the present invention, T4 ═ 60 ℃; Δ t1 ═ 10 ℃; Δ t2 ═ 30 ℃.
If Th is more than or equal to 60 ℃, the operation rate of the fan 3 is 80 percent;
if Th is more than or equal to 50 and less than 60, the operation rate of the fan 3 is 60 percent;
if Th is more than or equal to 30 and less than 50, the operation rate of the fan 3 is 40 percent;
if Th is less than or equal to 30, the operation rate of the fan 3 is 30%.
Of course, if T4, Δ T1 'and Δ T2' have other values, the object of the present invention can be achieved.
In addition, the constant temperature control method for the wine cabinet further comprises the following steps:
detecting the continuous heating time length Sl of the heating wire 1;
setting a time length threshold value Sv;
and if the Sl is more than or equal to the Sv, controlling the power-off and power-off time Sp of the heating wire 1.
In the present embodiment, Sv is 48h, and Sp is 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 also forcibly cut 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 casing 10 for detecting the ambient temperature Te, a second temperature sensor disposed inside the casing 10 and away from the heater strip 1 for detecting the temperature Tr inside the wine cabinet 100, and a third temperature sensor 2 disposed inside the casing 10 and close to the heater strip 1 for detecting the temperature Th of the heater strip 1. In addition, the box body comprises a back plate, and the heating wires 1 are arranged by being attached to the back plate; 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 when the heating wire 1 works to the whole box body, so that the temperature is more uniform.
In summary, the invention provides a wine cabinet 100 and a constant temperature control method thereof, when the environment 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 the unstable temperature in the wine cabinet 100 caused by the overhigh or overlow heating power P of the heating wire 1 is prevented; moreover, the operation rate of the heating wire 1 can be selected according to the temperature Th of the heating wire 1 and the third temperature threshold T3, and the uneven temperature in the wine cabinet caused by the unreasonable distribution of the working time of the heating wire is further prevented.
