为满足红酒的存储要求，在市场出现了具有加湿功能的酒柜，其具体设计是在储酒室内设置一个加湿水盒，同时对应设置加湿风机，通过加湿风机不断地向加湿水盒输送气流，将加湿水盒中的水转换成水蒸气，进而吹入到酒柜内，实现加湿功能。水盒中的水需要定期人工添加且对酒柜中的加湿为无论何种工况均通过加湿风机一直工作吹水来实现。然当酒柜处于不同的工况时，酒柜中的湿度会发生明显的变化，存在湿度超标、湿度适宜、湿度严重损失等多种情况。如果加湿风机保持设定功率持续加湿运行，使得输送至酒柜内的水蒸气的量不变，这样则会导致酒柜内部湿度值变化波动大，湿度不恒定，尤其是在制冷时，储酒室内部水蒸气损耗多，湿度下降快，使得酒柜内部无法保持存储红酒所需要的湿度。In order to meet the storage requirements of red wine, wine cabinets with humidification function have appeared in the market. The specific design is to set a humidification water box in the wine storage room and set a humidification fan correspondingly. The humidification fan continuously delivers airflow to the humidification water box. The water in the humidifying water box is converted into water vapor, and then blown into the wine cabinet to realize the humidifying function. The water in the water box needs to be manually added on a regular basis and the humidification in the wine cabinet is achieved by blowing water through the humidification fan working all the time regardless of the working conditions. However, when the wine cabinet is in different working conditions, the humidity in the wine cabinet will change significantly, and there are many situations such as excessive humidity, appropriate humidity, and serious humidity loss. If the humidification fan keeps the set power and continues to humidify, the amount of water vapor transported to the wine cabinet will not change, which will cause large fluctuations in the humidity value inside the wine cabinet, and the humidity will not be constant, especially during cooling. There is a lot of water vapor loss inside the room, and the humidity drops quickly, making the inside of the wine cabinet unable to maintain the humidity required for storing red wine.

本实施例中的恒温恒湿酒柜对应的具体的温湿度控制方法如下：其包括有压缩机700前N次启停对应的温湿度控制方法和N次启停后的控制方法，为方便控制，本实施例中先对酒柜的初始参数进行设定：设压缩机700的开停机温差为△T，因为要实现储酒腔210内恒温，需要限制压缩机700的开机温度和停机温度，开停机温差越小，恒温效果越好。The specific temperature and humidity control method corresponding to the constant temperature and humidity wine cabinet in this embodiment is as follows: it includes the temperature and humidity control method corresponding to the first N start and stop times of the compressor 700 and the control method after the N start and stop times, for the convenience of control In this embodiment, the initial parameters of the wine cabinet are set first: Set the temperature difference between on and off of the compressor 700 as △T, because to achieve a constant temperature in the wine storage chamber 210, the startup temperature and shutdown temperature of the compressor 700 need to be limited. The smaller the temperature difference between start and stop, the better the thermostat effect.
第二预设湿度为：RH-H，H为第一湿度偏差，第一预设湿度为：RH-L，L为第二湿度偏差；设定温度为：Ts，储酒腔210内实际温度为：T1，储酒腔210中实际湿度为：RH。预设温度偏差为：1.5，The second preset humidity is: RH-H, H is the first humidity deviation, the first preset humidity is: RH-L, L is the second humidity deviation; the set temperature is: Ts, the actual temperature in the wine storage chamber 210 Is: T1, the actual humidity in the wine storage cavity 210 is: RH. The preset temperature deviation is: 1.5,

第二预设湿度为设定湿度和第二湿度偏差之差。The second preset humidity is the difference between the set humidity and the second humidity deviation.
本实施例中的第一预设温度小于第二预设温度，即第一预设温度对应的为储酒腔210中的下限温度，第二预设温度对应的为储酒腔210中的上限温度；The first preset temperature in this embodiment is less than the second preset temperature, that is, the first preset temperature corresponds to the lower limit temperature in the wine storage cavity 210, and the second preset temperature corresponds to the upper limit temperature in the wine storage cavity 210 temperature;
第一预设湿度小于第二预设湿度，即第一预设湿度为储酒腔210中的下限湿度，第二预设湿度为储酒腔210中的上限湿度，对应的温度波动区间为：Ts-1.5-Ts+1.5的区间范围。The first preset humidity is less than the second preset humidity, that is, the first preset humidity is the lower limit humidity in the wine storage chamber 210, and the second preset humidity is the upper limit humidity in the wine storage chamber 210, and the corresponding temperature fluctuation interval is: Ts-1.5-Ts+1.5 interval range.

Therefore, the temperature and humidity control method in this embodiment is to first control the action of the compressor 700 so that the temperature in the wine storage chamber 210 reaches the set point temperature. During specific control, the temperature in the wine storage chamber 210 is detected by the temperature detection element, and the compressor 700 and the air supply device 600 are controlled to start and stop synchronously according to the temperature.

在前N次压缩机700控制过程中，将送风装置600和压缩机700同步启停，是为了将储酒腔210中的温度快速拉到预设温度，使得储酒腔210中的温度先达到酒柜内存储的温度需求。During the first N times of controlling the compressor 700, the air supply device 600 and the compressor 700 are started and stopped synchronously to quickly pull the temperature in the wine storage chamber 210 to a preset temperature, so that the temperature in the wine storage chamber 210 is first Meet the temperature requirements for storage in the wine cabinet.
步骤B:压缩机700N次启停后的温湿度控制方法：Step B: The temperature and humidity control method after the compressor starts and stops 700N times:

本实施例中提出的恒温恒湿酒柜控制方法的具体执行过程为：The specific execution process of the constant temperature and humidity wine cabinet control method proposed in this embodiment is:
先控制整个酒柜上电开机，同时控制压缩机700和送风装置600开始运行，在前N次运行时，仅仅通过温度检测元件传递储酒腔210内温度给控制器来控制蒸发器和送风装置600的启停，本实施例中N取10次，当然N也可以取大于10的其它值，在此不做具体限定，只有可使得在N次启停后储酒腔210内温度基本达到相对恒定即可，在前10次运行时，只要检测到储酒腔210内温度值达到第一预设温度，则控制压缩机700和送风装置600停机。First control the entire wine cabinet to power on, and at the same time control the compressor 700 and the air supply device 600 to start operation. During the first N operations, only the temperature in the wine storage chamber 210 is transmitted to the controller through the temperature detection element to control the evaporator and air supply For the start and stop of the device 600, N is taken 10 times in this embodiment. Of course, N can also take other values greater than 10. It is not specifically limited here, only that the temperature in the wine storage cavity 210 can be basically reached after N times of start and stop. It can be relatively constant. In the first 10 runs, as long as it is detected that the temperature in the wine storage cavity 210 reaches the first preset temperature, the compressor 700 and the air supply device 600 are controlled to stop.
只要检测到储酒腔210内温度值达到第二预设温度，则控制压缩机700和送风装置600开启。在运行10次后储酒腔210内温度基本达到稳定；As long as it is detected that the temperature value in the wine storage cavity 210 reaches the second preset temperature, the compressor 700 and the air blowing device 600 are controlled to be turned on. After running for 10 times, the temperature in the wine storage cavity 210 is basically stable;
然后继续检测储酒腔210内的温度，当储酒腔210内温度第N+1次达到第二预设温度时，则控制压缩机700、送风装置600开机；开机运行一段时间后，检测储酒腔210内的温度否达到第一预设温度或储酒腔210内湿度是否达到第一预设湿度，若是则控制压缩机700停机，送风装置600继续运行，由于湿度或温度已经达到了下限值，若压缩机700继续运行，则会导致温度会继续下降且压缩机700运行则会制冷会吸附大量水蒸气进而导致湿度值也会下降，此时为保持储酒腔210内的湿度和温度相对恒定，应控制压缩机700停机。Then continue to detect the temperature in the wine storage chamber 210. When the temperature in the wine storage chamber 210 reaches the second preset temperature for the N+1th time, the compressor 700 and the air supply device 600 are controlled to start; Whether the temperature in the wine storage chamber 210 reaches the first preset temperature or the humidity in the wine storage chamber 210 reaches the first preset humidity, if so, the compressor 700 is controlled to stop, and the air supply device 600 continues to operate, because the humidity or temperature has reached If the compressor 700 continues to run, the temperature will continue to drop, and the compressor 700 will absorb a large amount of water vapor during cooling, which will cause the humidity to drop. At this time, it is necessary to maintain the temperature in the wine storage chamber 210. The humidity and temperature are relatively constant, and the compressor 700 should be controlled to stop.
如若湿度达到第一预设湿度，压缩机700停机则会减缓湿度的降低，同时送风装置600仍运行，可使得其将蒸发器上的水蒸气吹向储酒腔210，进而以保持储酒腔210内部湿度恒定。If the humidity reaches the first preset humidity, the compressor 700 shuts down to slow down the decrease in humidity, while the air supply device 600 is still running, which can make it blow the water vapor on the evaporator to the wine storage cavity 210 to maintain the wine storage. The humidity inside the cavity 210 is constant.
若温度达到第一预设温度，压缩机700停机后，不会继续制冷，则会使得储酒腔210内温度会升高，同时送风装置600转动，吹出部分冷量保证箱内温度不会升到上限，以此来保持箱内温度相对恒定。If the temperature reaches the first preset temperature, the compressor 700 will not continue to refrigerate after it is stopped, which will cause the temperature in the wine storage chamber 210 to rise, and the air supply device 600 rotates to blow out part of the cold to ensure that the temperature in the box will not Raised to the upper limit to keep the temperature in the box relatively constant.
若否，即储酒腔210内的温度未达到第一预设温度和储酒腔210内湿度未达到第一预设湿度，则控制压缩机700、送风装置600继续运行，通过压缩机700控制蒸发器制冷，送风装置600实现加湿，以实现保持储酒腔210中恒温恒湿的效果。If not, that is, the temperature in the wine storage cavity 210 has not reached the first preset temperature and the humidity in the wine storage cavity 210 has not reached the first preset humidity, the compressor 700 and the air supply device 600 are controlled to continue to operate, and the compressor 700 The evaporator is controlled to cool, and the air supply device 600 realizes humidification, so as to achieve the effect of maintaining the constant temperature and humidity in the wine storage cavity 210.
若储酒腔210内的温度达到第一预设温度或储酒腔210内湿度达到第一预设湿度控制压缩机700停机后，则需要对储酒腔210中温度检测控制，由于压缩机700停机，储酒腔210中温度会上升，先检测储酒腔210内温度是否超过温度波动区间的上限，若没有超过温度波动区间的上限，则代表储酒腔210内温度相对恒定，然后进一步检测储酒腔210内的湿度，若储酒腔210内湿度达到第二预设湿度即湿度上限时，为保持储酒腔210内湿度恒定，则对应控制送风装置600停机，吹向出储酒腔210的水蒸气的量大量减少，使得储酒腔210中湿度下降，进而使得储酒腔210中的湿度也保持相对恒定；若储酒腔210内湿度未达到第二预设湿度即湿度上限时，则可控制送风装置600继续运行，进行加湿，并且还可以向储酒腔210中吹入少量冷量以平衡压缩机700停机后的温升，使得储酒腔210中保持相对恒定的温度和湿度；If the temperature in the wine storage chamber 210 reaches the first preset temperature or the humidity in the wine storage chamber 210 reaches the first preset humidity control compressor 700 is stopped, the temperature in the wine storage chamber 210 needs to be detected and controlled. When the machine stops, the temperature in the wine storage chamber 210 will rise. First, check whether the temperature in the wine storage chamber 210 exceeds the upper limit of the temperature fluctuation interval. If it does not exceed the upper limit of the temperature fluctuation interval, it means that the temperature in the wine storage cavity 210 is relatively constant, and then check further The humidity in the wine storage cavity 210. If the humidity in the wine storage cavity 210 reaches the second preset humidity, that is, the upper limit of humidity, in order to keep the humidity in the wine storage cavity 210 constant, the air supply device 600 is correspondingly controlled to stop and blow out the wine storage. The amount of water vapor in the cavity 210 is greatly reduced, so that the humidity in the wine storage cavity 210 decreases, and the humidity in the wine storage cavity 210 also remains relatively constant; if the humidity in the wine storage cavity 210 does not reach the second preset humidity, that is, the humidity Within a limited time, the air supply device 600 can be controlled to continue to operate for humidification, and a small amount of cold energy can be blown into the wine storage cavity 210 to balance the temperature rise after the compressor 700 is stopped, so that the wine storage cavity 210 can maintain a relatively constant Temperature and humidity;
在压缩机700停机后若储酒腔210内温度超过了温度波动区间的上限，则继续检测温度是否超过了第二预设温度值，若是，则控制压缩机700开机；若否，则继续保持压缩机700停机状态。After the compressor 700 stops, if the temperature in the wine storage chamber 210 exceeds the upper limit of the temperature fluctuation interval, continue to detect whether the temperature exceeds the second preset temperature value, if so, control the compressor 700 to start; if not, continue to maintain The compressor 700 is in a shutdown state.
在压缩机700和送风装置600均停机后，继续检测储酒腔210内温度，若储酒腔210内温度达到第二预设温度时，且压缩机700停机时间超过5分钟后，控制压缩机700和送风装置600再次开机，然后继续检测储酒腔210内温度，若储酒腔210内温度在温度波动区间内，则继续检 测储酒腔210内的温度否达到第一预设温度或储酒腔210内湿度是否达到第一预设湿度，并判断压缩机700的启停；After the compressor 700 and the air supply device 600 are shut down, continue to detect the temperature in the wine storage chamber 210. If the temperature in the wine storage chamber 210 reaches the second preset temperature and the compressor 700 is stopped for more than 5 minutes, control the compression The machine 700 and the air supply device 600 are turned on again, and then continue to detect the temperature in the wine storage chamber 210. If the temperature in the wine storage chamber 210 is within the temperature fluctuation range, continue to detect whether the temperature in the wine storage chamber 210 reaches the first preset temperature Or whether the humidity in the wine storage cavity 210 reaches the first preset humidity, and determine whether the compressor 700 starts or stops;
若储酒腔210内温度达到了温度波动区间下限值，则控制压缩机700、送风装置600同步停机，保证储酒腔210内部的温度值。If the temperature in the wine storage cavity 210 reaches the lower limit of the temperature fluctuation interval, the compressor 700 and the air blowing device 600 are controlled to stop synchronously to ensure the temperature value inside the wine storage cavity 210.
本实施例中通过实时检测储酒腔210中的温度和湿度，并通过压缩机700和送风装置600的交替启停来控制酒柜内的温度和湿度，保证了酒柜的恒温恒湿。In this embodiment, the temperature and humidity in the wine storage chamber 210 are detected in real time, and the temperature and humidity in the wine cabinet are controlled by the alternate start and stop of the compressor 700 and the air supply device 600, which ensures the constant temperature and humidity of the wine cabinet.
自压缩机700停机到压缩机700后N+N次启停的温度湿度控制方法，检测储酒腔210内温度值是否在预设温度对应的温度波动区间内，若在预设温度的温度波动区间内，通过检测到的储酒腔210内湿度值是否达到第二极限湿度值来控制送风装置600的启停，在压缩机700再次开启后通过检测到的储酒腔210内温度是否达到第一预设温度或储酒腔210内湿度是否达到第一预设湿度来控制压缩机700的启停；若检测到的储酒腔210内温度不在预设温度对应的温度波动区间内，则通过检测到的储酒腔210内温度值来控制压缩机700、送风装置600同步启停。The temperature and humidity control method for N+N times after the compressor 700 stops to the compressor 700 starts and stops to detect whether the temperature value in the wine storage chamber 210 is within the temperature fluctuation interval corresponding to the preset temperature, and if it is within the temperature fluctuation range of the preset temperature In the interval, the start and stop of the air supply device 600 is controlled by whether the detected humidity value in the wine storage chamber 210 reaches the second limit humidity value.
