The specific embodiment
Be illustrated in figure 1 as the structural representation of damping device, damping device 1 is divided into the two large divisions in Fig. 1, and a part is placed and added wet stock 3, and this part is a left-hand component, and a part is placed miniature humidification fan 2, and this part is a right half.When device utilizes the condensed water humidification, have the hole in the front portion of left half; Damping device also can adopt the mode of adding water except that utilizing condensed water.
As Fig. 2, Fig. 3, Figure 4 shows that the three-view diagram of this device, wherein 8 parts are that device is deposited the place that adds wet stock, and roughly between 20 to 40mm, the width of L2 is roughly between 30 to 50mm for the thickness of L1,4 parts are the places of placing fan, and the width of L3 is roughly between 50 to 70mm; Height of devices L5 is between 90 to 120mm, and width L4 is between 80 to 110mm, and the bore L7 of fan is between 70 to 100mm, and the connecting hole L6 between device and the fan is between 40 to 80mm.
Fig. 5, Fig. 6 are the outside drawing that adds wet stock 3, and material is made up of efficient suction/moisture releasing material (as antibacterial nonwoven cloth made), and in order to increase the surface area that distributes of material, the spy is designed to alveolate texture.Among Fig. 5, the length a that adds wet stock 3 is between 90 to 120mm, width b between 80 to 110mm, thickness c at 20mm between the 50mm.
The humidification principle: 7 li of the water receiving tanks of the condensed water inflow inner container of icebox that produces in the refrigerator work process, and assemble there.Damping device 1 can place in the water receiving tank 7, and the immersion of the anti-bacterial wet-absorbing material 3 in the device is partially immersed in the water, with the moisture suction apparatus inside in the tank, makes the hygroscopic material of device inside keep constant humidity; Under the effect of fan 2, humid air is blown in the cold compartment of refrigerator 6, the humidity in the refrigerating chamber 6 is remained in the scope that is beneficial to fresh-keeping of vegetables.
Air-humidification method: the humidification control circuit detects freezer compressor start working after, the delayed startup damping device; After detecting freezer compressor and quitting work, damping device is closed down in time-delay.Selected delay time was at 3-15 minutes.
As shown in Figure 7, the application of high-efficiency humidifier in refrigerator: high-efficiency humidifier 1 can design in the rhone 7 of refrigerator, utilizes the condensed water of refrigerator to carry out humidification.Device also can be without the condensed water of refrigerator, but periodically to the device moisturizing, and to add wet stock moistening to keep.Utilize a scheme of refrigerator condensed water to be, damping device 1 is arranged at the upper position of water receiving tank 7, and the bottom of humidifier is in water receiving tank 7, and the characteristics of this scheme are not need to add water to damping device.The osculum 5 of refrigerating chamber 6 is not in the bottom of water receiving tank 7, has with a certain distance from the bottom, to guarantee having enough water to use for humidification in the water receiving tank 7.
Increase damping device 1 in cold compartment of refrigerator 6, the condensed water in the refrigerating chamber 6 enters water receiving tank 7, and the absorbent material 3 in the damping device 1 enters moisture absorption in the cold compartment of refrigerator 6 with humid air under the effect of fan 2, keeps the high humility in the cold compartment of refrigerator 6.When the water in the water receiving tank 7 surpassed discharge outlet 5 too much, redundant moisture was just discharged refrigerator from drainpipe, avoided overflowing entering in the refrigerating chamber 6.
Shown in Figure 14 (a), Figure 14 (b), adopt press work, damping device time-delay a period of time work; Press stops, the working method that the damping device time-delay stops.
The characteristics of this method are: adopt press work, device time-delay a period of time work; Press stops, the working method that the device time-delay stops.The method further shortens the running time of device when guaranteeing that humidity is higher.The circuit of relay control section is shown in Figure 14 (a), compressor is in parallel with relay K M1, the refrigerator power supply was controlled time relay KT1 by the normal battle of relay K M1, and the refrigerator power supply is controlled time relay KT2 by the normally closed of relay K M1 simultaneously; Transformer whether electricly control by two-way, control after the normally opened contact of one route relay K M1 is connected with the timing closing contact of time relay KT1, control got dead electricity to transformer after this two-way parallel connection and controls after the normally-closed contact of another road KM1 was connected with the time-delay break contact of time relay KT2.Transformer becomes after the low pressure 220v high pressure again through after unsteady flow and the voltage stabilizing damping device being powered.The delay time of regulating time-delay relay KT1 just can control compressor open the back damping device start working preceding between lag time; The delay time of regulating time-delay relay KT2 just can be controlled compressor and close afterwards that damping device continues that a period of time of work again.
When compressor gets electricly, KM1 gets electric, so the normally opened contact closure of KM1, time relay KT1 gets; KM1 gets when electric, and its normally-closed contact disconnects, and this moment, KT1 got electric KT2 dead electricity, and the KT1 trigger is delayed time and arrived, the KT1 timing closing closing of contact, because the normally opened contact of KM1 is closed, and so that the input coil of transformer T1 gets is electric, damping device work.When the compressor dead electricity, the KM1 dead electricity, open the normal battle of KM1, normally closed closed, so the KT1 dead electricity, KT2 gets, power supply is given transformer T1 in the back because the normally-closed contact of KM1 is connected with the time-delay break contact of KT2, so T1 continues electricly, damping device works on, meanwhile, the KT2 trigger, delay arrival time, the time-delay break contact of KT2 is opened, transformer T1 dead electricity, damping device quits work.
The damping device control circuit adopts the mode of microprocessor to control shown in Figure 15 (a), 15 (b), adopts press work, damping device time-delay a period of time work; Press stops, the working method that the damping device time-delay stops.Also can control by the mode of microprocessor control, here be that example is controlled with 8031 single-chip microcomputers, circuit diagram is shown in Figure 15 (a), in the drawings 8031 RAM that extend out the 4k byte being used for program stores, wherein the operating state signal of compressor is by the input of P30 mouth, single-chip microcomputer is judged this signal, if compressor behavior is a high level signal, start soft delayer 1 and see XTAL1 among the figure, the P27 interface is connected after arriving the time of setting, the adhesive of relay K M2 contact, the damping device running; If compressor behavior is a low level signal, start delayer 2 and see XTAL2 among the figure, arrived the time of setting after, the P27 interface disconnects, damping device shuts down.Figure 15 (b) is the fundamental diagram of this enforcement.
Control flow chart as shown in figure 16, with the method adopt the press operation after 4 minutes damping device rerun, press stops that damping device stops again after 10 minutes, humidity situation in the refrigerator as shown in figure 17, adopt this kind control mode, the humidity in the refrigerator can be controlled between 85% to 95% all the time.Suitable good of humidification effect can be satisfied the demand of refrigerator humidification.
Contrast the effect of various air-humidification methods below:
Under humidification situation not, rectangular curve is a compressor start-stop curve as shown in Figure 8, and middle is the refrigerating chamber moisture curve, and following is the temperature of refrigerating chamber curve.As can be seen, when compressor start, the temperature and humidity time-delay in the refrigerating chamber reaches for a moment and begins rapid decline after the highest among the figure; After compressor quits work, because the condensation of refrigerator backboard, the refrigeration indoor temperature can be delayed time and be reached minimum temperature for a moment, and have a large amount of hydrogenesis simultaneously, still can delay time one section after compressor quits work and condense, cause the refrigeration indoor humidity constantly to descend, and time-delay reach minimum, this moment, the humidity in the refrigerating chamber was lower than the standard humidity under the temperature at that time, and humidity rises and can rise early than temperature.
Moisture curve figure is that damping device moves humidification continuously as shown in Figure 9, and following curve is a temperature line, and top curve is the humidity line, and the environment temperature of test is 15 degree, and envionmental humidity is 40%.We can see that the highest relative humidity is 98.9% in the refrigerator, and minimum humidity is 90.2%, and humidity is fluctuation up and down in this scope, refrigerating chamber moistening effect ideal.But sometimes humidity can be higher than requirement and cause waste, and damping device turns round continuously, and aging easily, the life-span shortens greatly.
Moisture curve figure is a damping device intermittent duty humidification as shown in figure 10, and following curve is a temperature line, and top curve is the humidity line, and middle rectangular lines is represented the opening and closing of damping device; The environment temperature of test is 21 degree, and ambient humidity is 37%.We can see humidity fluctuation up and down between 75% to 97% in the refrigerator.The fluctuation of this kind humidification method is too big, and humidity is low excessively sometimes.
Moisture curve figure is damping device and the synchronous start and stop of compressor as shown in figure 11, and the environment temperature of test is 19 degree, and ambient humidity is 45%, adopts this kind mode, and moisture curve presents regular variation, and refrigerator humidity is fluctuation up and down between 75% to 90%.Sometimes still there is the low excessively situation of humidity.
Moisture curve figure is damping device and the asynchronous start and stop of compressor as shown in figure 12, can keep the interior humidity of refrigerator preferably a higher level, but fluctuating range is bigger, still has the lower situation of humidity.
As shown in figure 13 moisture curve figure be start simultaneously with compressor, time-delay closing, be that example is tested to delay time 10 minutes, the environment temperature of test is 20 ℃, ambient humidity is 55%.Adopt this kind mode, moisture curve presents regular variation, and refrigerator humidity is fluctuation up and down between 83% to 92%.
Moisture curve figure is and compressor delayed startup, time-delay closing as shown in figure 17, damping device reruns after adopting press to move 4 minutes, press stops that damping device stops again after 10 minutes, humidity situation in the refrigerator as shown in the figure, adopt this kind control mode, humidity in the refrigerator can be controlled between 85% to 95% all the time, and is stable and regular.Suitable good of humidification effect can be satisfied the demand of refrigerator humidification; It is a kind of better controlled mode.
