Description of the invention: [Technical field of the invention] The present invention relates to a method and a circuit for controlling the moisture content in a cabinet, and in particular, a method for maintaining the water content of the interior of the storage cabinet (4) and [previously Technology] For items that must be stored in a constant water content environment, such as ancient - cultural relics, children, stamps and other precious things, mouth, in order to avoid too low water content - environmentally induced cracking, damage, etc. 'electronic The storage cabinet can be said to be an excellent choice. It uses electronic control to detect the water content in the cabinet: ", the user's water content threshold value, can actively adjust the air moisture content in the cabinet to create A stable water content preservation environment. The most common humidification technology today should be an ultrasonic humidifier. The humidification system is in the storage cabinet. (4) The high-frequency ultrasonic waves atomize the water and then diffuse into the air in the cabinet. $ and this kind of ultrasonic humidification technology has the following defects: · f use pure water, otherwise it will damage the ultrasonic head due to the contamination of other impurities to the ultrasonic head (vibration), shorten its use Life. ^ · Not suitable for small space antelope humidification, due to the atomization after the + point in J must be even / Kun combined in the air to improve the environmental water i, due to 1 use, sonic atomization technology must be sufficient to humidify Empty Fe1, if the space inside M is too small, it will accumulate water, which will greatly increase the water content, which is not suitable for use. It is necessary to replenish the water immediately, and the 1304331 water storage will be continuously consumed during the atomization process, so the user must monitor the water volume from time to time. If the amount of water is too low, it must be artificially added. 4, easy to mold mold, used for humidification, storage of water for a long time, easy to produce bacteria, ~ the sun is cloudy in the mountains, suitable for the growth of mold, so it is more likely to cause the storage of the fungus or The damage of other microorganisms. The monthly multi-test number ', the figure is not' is the change of the water content after the control of the current humidification technology: the water content variation curve can be seen from the figure, the oscillation of the water content is severely intertwined, the main cause Even if the humidified water and gas molecules are too large, they will fall before the air is mixed (4) into water, and if the cabinet is too small to humidify; the rate is too / ", the method is effective to mix with the air, making the water Directly attached In the internal surface of the cabinet but the air is still dry, when the cabinet is too wet, the Department can not perform dehumidifying action inside the cabinet after the long run it is easy to produce in moldy smell. SUMMARY OF THE INVENTION The present invention is directed to the control of 3 water in the existing storage cabinet, which is difficult to maintain constant

Here, 2 @ 0 ψΒ V, [12 time, the internal/external opening of the door panel (2 2 0) depends on the inclusion of both the water and the water in the cabinet. When the water content in the cabinet is critical, Then the door 4c / is lower than the d value of the inner boundary of the d, the J door plate (2 2 〇) is maintained at the water content in the cabinet is higher than the water level of the water gaze ^ 3 κ, the door panel (2 2 〇) Then, the heating state is turned off while the state is turned on. The fan (23〇) inside the humidification box (200) is controlled, and the transmission must be frequently turned on/off. In a period of time, the fan (2 ^ ϋ ) is based on the heater's helmet mouth ",, and the action is determined whether it should be activated. If heated, the fan J (2 3 〇) will be turned on to accelerate the planting. In the main body (丄二〇): the circulation of the airflow increases the efficiency of the diffusion of water molecules. It is open for a period of time. It is not necessary to maintain the right 疋 in the entire Τ2 day segment. Without action, the fan will remain stationary for the entire Τ2 period. #凊 Referring to the second figure, the second embodiment of the present invention is within the allowable range of the water content limit value and the lower #2%, wherein According to the need to sigh, as the upper limit and lower limit of the operation of the humidification box, the upper middle limit value of 8 will determine the internal/external action of the door panel (2 2 0). For the opening or not, the action mode also has two adjustment modes: & 1 · The cycle adjustment mode also periodically provides a series of drive signals, the time of each drive signal is T1 I α ', two adjacent drive signals There is an appropriate interval between 1304331 segments Τ2, in the drive letter When it is produced, the door panel (2 2 Q ) inside the humidification box (2 〇〇) will be activated. The Η plate (2 2 Q ) is opened to allow the desiccant (2 1 〇) to absorb moisture. Among them, the door panel (2 2 〇) The externally opened time is 4 predetermined time t, and the predetermined time t1 is equal to the duration T1 of the driving signal. 11 Maneuvering adjustment mode in the period in which no driving signal exists, that is, in the T2 period, the storage cabinet enters-maneuver adjustment Mode: In this mode, the start of the heater is controlled according to the water content inside the cabinet body (work 0 。). If the water volume is lower than the lower allowable value, the heater is forced to dry: M 1 0) can release water molecules and increase the cabinet body (100) = water = continuous humidification until the water content in the cabinet reaches the water content, the value "turns off the heater, so that the desiccant (release water molecules During this T2 period, the door panel 0) no longer holds the external opening system depending on the water content in the cabinet. When the limit value is reached, the wheel (22〇) is maintained in the inner: water:: the amount is higher than the At the upper limit, the door panel (22Q) is turned into a water-containing humidification box (2 〇 The internal wind, '幵,.

By the cooperation of the above two modes of operation, the present invention can provide a storage environment with a small change in water content, and the change of the water content inside the cabinet body (丄") As shown by the curve, a small change is presented based on the critical value or the upper and lower limit values, and the change range is also within the range of the allowable bee. Referring to the third figure, the mouth circuit is the control circuit of the present invention. The circuit includes a single circuit (丨〇), a connection _electric dust conversion unit (2 〇), and a power (four) replacement unit (2). 〇) providing a power supply M to the control unit ,), the control unit (10) is composed of a single-chip component, and the internal water content threshold value or the upper and lower limit values are set internally and stored, The control unit (1〇) has a complex signal output pin, and the control signal sent by the chatter includes the aforementioned control signal and the corresponding control signal of the heated door panel, the fan and the like; a water content sensor (3 〇)' Connected to the control unit 2 to prepare the water content inside the storage cabinet, and (4) to the control unit (1 〇). The control program stored in the internal system (1 〇) is executed on ##, 铁&..., pure, and the control position is rounded up at the appropriate time: 疋 humidification box (2 〇〇) inside The action sequence of each component, two or two, cooperate with each other to create a constant protection environment. The heart-shaped storage ring,...the above is the same as the existing humidification technology. It has the following 11 1304331. Advantages: 1 · Eliminating the problem of continuous monitoring of water storage, the present invention does not atomize liquid water. Wet, but directly absorb the water molecules contained in the air and then release them, so no additional water is needed. 2 • Using a sterile water source, the humidified water molecules are heated at a high temperature to ensure that the water knife is flawless ‘and does not affect the stored items. 3. It can ensure constant humidity, and the invention has the functions of humidification and dehumidification, and can accurately control the water content inside the storage cabinet.肇 [Simplified description of the drawings] Fig. 1 is a waveform diagram of control signals of the first embodiment of the control method of the storage cabinet of the present invention.
