DETAILED DESCRIPTION

[0024] The specific implementation of the utility model is further described below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Embodiment one:

[0026] A rotary dehumidifier, such as Figure 1 and Figure 2As shown, the dehumidifier is divided into two parts, a shell 1 located on the outside and a storage box 2 located on the inside. The shell 1 includes a polygonal shell and a rear cover plate 4. The storage box 2 includes a box body and a front cover plate 3. The rear cover plate and the shell can be separated, and the front cover plate and the box body can also be separated. The shell 1 and the storage box 2 can be pulled apart. There are several fixing holes on the edge of the front cover plate 3 of the storage box 2, and threaded holes are also provided at the corresponding position of the front end of the shell 1. The fixing holes and threaded holes are penetrated by screws to achieve the fixing between the shell 1 and the storage box 2. The storage box 2 body fits the cavity inside the shell 1. The storage box 2 is used to accommodate various components inside the dehumidifier. When a certain component inside needs to be replaced, the screws are removed and the storage box 2 is pulled out to replace the component. An air inlet 8 is provided on the front cover plate 3, and an air outlet 9 is provided on the rear cover plate 4. The outside air enters from the air inlet 8 and flows out from the air outlet 9.

[0027] like Figure 3 As shown, the dehumidification wheel 501 is installed near the middle of the containing box 2, and the cavity space in the containing box 2 is divided into two cavities in the left and right sides. The cavity near the air inlet 8 is the air inlet cavity 6, and the cavity near the air outlet 9 is the air outlet cavity 7. The air inlet cavity 6 is divided into two parts, the upper cavity is the processing area 601, and the lower cavity is the regeneration area 602. A heater 10 is arranged at the bottom of the regeneration area 602. When dehumidifying, the outside air flows in from the air inlet 8, and at the same time, the dehumidification wheel 501 rotates slowly to ensure that the whole dehumidification is a continuous process. When the treated air passes through the treatment area 601 of the wheel, the water vapor therein is adsorbed by the hygroscopic medium in the wheel, and the water vapor undergoes phase change at the same time, and releases latent heat. The wheel also gradually tends to saturation due to the absorption of a certain amount of moisture. At this time, the treated air becomes dry and hot air due to the reduction of its own moisture and the release of latent heat. At the same time, in the regeneration area 602, the other air first passes through the regeneration heater 10, becomes high-temperature air and passes through the saturated rotor after moisture absorption, so that the moisture adsorbed in the rotor evaporates, thereby restoring the dehumidification capacity of the rotor; at the same time, the regeneration air becomes humid air due to the evaporation of moisture. Afterwards, the humid air is discharged to the outside through the regeneration wind.

[0028] like Figure 4As shown, the dehumidification wheel 501 is composed of the air outlet 9 bracket 5, the dehumidification wheel 501, the motor bracket 502, the wheel motor 503 and other parts. The air outlet 9 bracket 5 is an irregular polygon, and its shape is consistent with the internal shape of the housing 1, ensuring that there is no other ventilation gap between the separated air inlet cavity 6 and the air outlet cavity 7 except the dehumidification wheel 501. There is a circle of fixing rings on the edge of the air outlet 9 bracket 5, and a number of fixing holes are set on the fixing ring. Bolts penetrate the fixing holes to fix the air outlet 9 bracket 5 in the containing box 2. The dehumidification wheel 501 is fixed in the middle of the air outlet 9 bracket 5. The wheel is synthesized by glass fiber and heat-resistant ceramic materials as the internal support carrier of the wheel, and special effective moisture absorption medium materials (such as high-efficiency silica gel). In this way, the high-efficiency moisture absorbent and the special honeycomb structure of the wheel itself not only ensure the huge surface area of ​​the wheel in contact with the air, but also improve the moisture absorption efficiency of the wheel and increase the moisture absorption capacity. The air outlet 9 bracket 5 has a horizontally fixed motor bracket 502, which is fixed to the air outlet 9 bracket 5 by bolts. A rotary motor 503 is fixed to the motor bracket 502 by bolts, and the rotary motor 503 is connected to the dehumidification wheel 501, and the dehumidification wheel 501 is driven to rotate by the rotary motor 503. The heater 10 is fixed to the lower half of the air outlet 9 bracket 5 by bolts.

[0029] The upper end of the front cover 3 is provided with a power cord outlet 15 and a switch 14. The external power supply can be connected through the power cord outlet 15, and the operation of the dehumidifier is controlled by the switch 14. A switching power supply is provided in the air inlet chamber 6, and the switching power supply is connected to the switch 14 to supply power to the switch 14. A controller 13 is fixed to the side of the accommodating chamber by bolts, and the controller 13 will be connected to other internal devices that need to be controlled, so as to control these devices to automatically perform corresponding operations. An electric energy meter 16 is also provided on the front cover 3, which is used to detect the voltage and current conditions inside the dehumidifier, so as to determine whether the internal part is in a normal working state, which is convenient for fault detection. At the same time, a jack 18 is provided on the front cover 3, and this jack 18 can be connected to an external switch line to extend the switch line. Thereby, the control switch 14 can be arranged in other positions, which is convenient for controlling the dehumidifier.

[0030] Embodiment 2:

[0031] In this embodiment, the dehumidifier is divided into two parts, namely, a shell 1 located on the outside and a storage box 2 located on the inside. The shell 1 includes a polygonal outer shell and a rear cover plate 4, and the storage box 2 includes a box body and a front cover plate 3. A number of fixing holes are arranged on the edge of the front cover plate 3 of the storage box 2, and threaded holes are also arranged at the corresponding positions of the front end of the shell 1. The fixing holes and threaded holes are penetrated by screws to achieve the fixation between the shell 1 and the storage box 2. The storage box 2 body fits the cavity inside the shell 1. The storage box 2 is used to accommodate various components inside the dehumidifier. When a certain component inside needs to be replaced, the screws are removed, and the storage box 2 is pulled out to replace the component. An air inlet 8 is arranged on the front cover plate 3, and an air outlet 9 is arranged on the rear cover plate 4. The outside air enters from the air inlet 8 and flows out from the air outlet 9.

[0032] like Figure 3 As shown, the dehumidification wheel 501 is installed near the middle of the containing box 2, and the cavity space in the containing box 2 is divided into two cavities in the left and right sides. The cavity near the air inlet 8 is the air inlet cavity 6, and the cavity near the air outlet 9 is the air outlet cavity 7. The air inlet cavity 6 is divided into two parts, the upper cavity is the processing area 601, and the lower cavity is the regeneration area 602. A heater 10 is arranged at the bottom of the regeneration area 602. When dehumidifying, the outside air flows in from the air inlet 8, and at the same time, the dehumidification wheel 501 rotates slowly to ensure that the whole dehumidification is a continuous process. When the treated air passes through the treatment area 601 of the wheel, the water vapor therein is adsorbed by the hygroscopic medium in the wheel, and the water vapor undergoes phase change at the same time, and releases latent heat. The wheel also gradually tends to saturation due to the absorption of a certain amount of moisture. At this time, the treated air becomes dry and hot air due to the reduction of its own moisture and the release of latent heat. At the same time, in the regeneration area 602, the other air first passes through the regeneration heater 10, becomes high-temperature air and passes through the saturated rotor after moisture absorption, so that the moisture adsorbed in the rotor evaporates, thereby restoring the dehumidification capacity of the rotor; at the same time, the regeneration air becomes humid air due to the evaporation of moisture. Afterwards, the humid air is discharged to the outside through the regeneration wind.

[0033] like Figure 4As shown, the dehumidification wheel 501 is composed of the air outlet 9 bracket 5, the dehumidification wheel 501, the motor bracket 502, the wheel motor 503 and other parts. The air outlet 9 bracket 5 is an irregular polygon, and its shape is consistent with the internal shape of the housing 1, ensuring that there is no other ventilation gap between the separated air inlet cavity 6 and the air outlet cavity 7 except the dehumidification wheel 501. There is a circle of fixing rings on the edge of the air outlet 9 bracket 5, and a number of fixing holes are set on the fixing ring. Bolts penetrate the fixing holes to fix the air outlet 9 bracket 5 in the containing box 2. The dehumidification wheel 501 is fixed in the middle of the air outlet 9 bracket 5. The wheel is synthesized by glass fiber and heat-resistant ceramic materials as the internal support carrier of the wheel, and special effective moisture absorption medium materials (such as high-efficiency silica gel). In this way, the high-efficiency moisture absorbent and the special honeycomb structure of the wheel itself not only ensure the huge surface area of ​​the wheel in contact with the air, but also improve the moisture absorption efficiency of the wheel and increase the moisture absorption capacity. The air outlet 9 bracket 5 has a horizontally fixed motor bracket 502, which is fixed to the air outlet 9 bracket 5 by bolts. A rotary motor 503 is fixed to the motor bracket 502 by bolts, and the rotary motor 503 is connected to the dehumidification wheel 501, and the dehumidification wheel 501 is driven to rotate by the rotary motor 503. The heater 10 is fixed to the lower half of the air outlet 9 bracket 5 by bolts.

[0034] The upper end of the front cover 3 is provided with a power cord outlet 15 and a switch 14. The external power supply can be connected through the power cord outlet 15, and the operation of the dehumidifier is controlled by the switch 14. A switching power supply is provided in the air inlet chamber 6, and the switching power supply is connected to the switch 14 to supply power to the switch 14. A controller 13 is fixed to the side of the accommodating chamber by bolts, and the controller 13 will be connected to other internal devices that need to be controlled, so as to control these devices to automatically perform corresponding operations. An electric energy meter 16 is also provided on the front cover 3, which is used to detect the voltage and current conditions inside the dehumidifier, so as to determine whether the internal part is in a normal working state, which is convenient for fault detection. At the same time, a jack 18 is provided on the front cover 3, and this jack 18 can be connected to an external switch line to extend the switch line. Thereby, the control switch 14 can be arranged in other positions, which is convenient for controlling the dehumidifier.

[0035] like Figure 5 and Figure 6As shown, the air outlet 9 on the rear cover 4 is divided into a dry air outlet 901 and a wet air outlet 902, and the wet air outlet 902 is located below the dry air outlet 901. At the same time, there is only one wet air outlet 902, and there are multiple dry air outlets 901. In this scheme, there are two dry air outlets 901, which are arranged side by side. Conventional dehumidifiers have one dry air outlet, which can dehumidify the whole house or a single fixed point. If multiple fixed points are used for dehumidification, it cannot be achieved. The air outlet is connected to the air duct, which can be selected according to the actual usage scenario. If the whole house is dehumidified, the dry air is ductless, and the single fixed point dehumidification can use the dry air single duct type, and the multiple fixed point dehumidification can use the dry air multi-duct type.

[0036] The air outlet cavity 7 is divided into two parts by a partition, namely a dry air cavity 701 and a wet air cavity 702. The partition is composed of two mutually perpendicular plates, so that the wet air cavity 702 presents a small square. The wet air outlet 902 is located within the wet air cavity 702, and the dry air outlet 901 is located within the dry air cavity 701. A temperature sensor 11 is also arranged in the wet air cavity 702.

[0037] like Figure 6 and Figure 7 As shown, both the dry air outlet 901 and the wet air outlet 902 are provided with air valves 19, and the air valves 19 can completely block the outlet passage. Each air valve 19 is connected to a separate motor 12. The air valve 19 can be driven by the motor 12 to rotate so as to control the dry and wet air volume. This rotary wheel system is equipped with a large air volume fan, and the wet air outlet 902 is equipped with a temperature sensor 11 to control the outlet temperature to maintain the temperature required for the rotary wheel dehydration. The control method is to control the wet air electric air valve 19, and automatically generate the required dehydration temperature by automatically controlling the air volume. When the ambient humidity is high, the dry air electric air valve 19 opens, increases the opening size of the dry air outlet 901, increases the air volume, thereby increasing the amount of processed air and the amount of air circulation. When the ambient humidity is close to the set humidity, the electric air valve 19 rotates, and the dry air electric air valve 19 gradually closes, reduces the opening size of the dry air outlet 901, reduces the processed air volume, and reduces the dew point temperature, thereby achieving the desired ambient humidity. The dry and wet air electric air valves 19 are all automatically controlled. The wet air air valve 19 is controlled to achieve a relatively stable dehydration air temperature, and the dry air air valve 19 is automatically controlled to achieve flexible control of the ambient humidity.

[0038] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
