Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] First Embodiment

[0025] Please refer to the reference. Figure 1 , Figure 2 and Figure 3 ( Figure 1 and Figure 2 (The hollow arrows in the diagram indicate the direction of airflow). This embodiment of the invention provides a dry humidification device 100 for humidification. It can maintain the relative humidity of the air passing through the desorption zone 112, ensuring humidification effect, improving user experience, and reducing power consumption, lowering operating costs, and being energy-saving and environmentally friendly.

[0026] In this embodiment, the dry-type humidifying device 100 is applied to an air conditioner cabinet, which is placed on the ground and can blow hot or cold air into the room to realize the functions of heating or cooling. The dry-type humidifying device 100 is used to blow humidified air into the room to realize the humidifying function. However, it is not limited to this. In other embodiments, the dry-type humidifying device 100 can be applied to an air conditioner hanging machine, an air conditioner ceiling machine, or can be separately provided, and the application scenarios of the dry-type humidifying device 100 are not specifically limited.

[0027] The dry-type humidifying device 100 includes an adsorption runner 110, a first air duct 120, a second air duct 130, a first fan 140, a second fan 150, and a plurality of heaters 160. The first air duct 120 and the second air duct 130 are independently provided and are both provided through the adsorption runner 110. The first fan 140 is installed in the first air duct 120 and is used to generate negative pressure to drive air to flow in the first air duct 120 and pass through the adsorption runner 110. The second fan 150 is installed in the second air duct 130 and is used to generate negative pressure to drive air to flow in the second air duct 130 and pass through the adsorption runner 110. The plurality of heaters 160 are all installed in the second air duct 130, and the heating temperatures of the plurality of heaters 160 are different, so that the air flowing in the second air duct 130 and passing through the adsorption runner 110 has different temperature distributions, thereby maintaining the relative humidity and ensuring the humidifying effect.

[0028] It is worth noting that the adsorption runner 110 is provided with an adsorption area 111, a desorption area 112, and a cooling area 113, and the positions of the heaters 160 correspond to the position of the desorption area 112. One end of the first air duct 120 is in communication with the outdoor, and the other end is in communication with the outdoor through the adsorption area 111. The first fan 140 is used to suck outdoor air and drive the outdoor air to pass through the adsorption area 111 and flow to the outdoor. In this process, the adsorption runner 110 can absorb the moisture of the outdoor air to make the adsorption runner 110 adhere to the moisture, and the dry air after absorbing moisture is discharged to the outdoor. One end of the second air duct 130 is in communication with the outdoor, and the other end is in communication with the indoor through the cooling area 113 and the desorption area 112 in sequence. The second fan 150 is used to suck outdoor air and drive the outdoor air to pass through the cooling area 113 and the desorption area 112 in sequence and flow to the indoor. In this process, the heaters 160 can heat the air passing through the desorption area 112 to form desorption wind, which can carry away the moisture adhered to the adsorption runner 110 and blow to the indoor to realize the humidifying function.

[0029] In this embodiment, the adsorption runner 110 is provided with a cooling zone 113, and when the outdoor air is driven by the second fan 150 to pass through the cooling zone 113, the outdoor air can cool the cooling zone 113 to reduce the temperature of the entire adsorption runner 110, thereby ensuring the humidifying effect. However, it is not limited to this, and in other embodiments, the adsorption runner 110 can also not be provided with a cooling zone 113, and at this time, one end of the second air duct 130 is in communication with the indoor, and the other end is only in communication with the indoor through the desorption zone 112, to realize the circulation of indoor air, and also can realize the humidifying function.

[0030] It should be noted that the adsorption zone 111, the desorption zone 112 and the cooling zone 113 are only virtual areas divided on the adsorption runner 110, and the adsorption zone 111, the desorption zone 112 and the cooling zone 113 will not rotate with the rotation of the adsorption runner 110. During the rotation of the adsorption runner 110, each position on the adsorption runner 110 can rotate to the adsorption zone 111, the desorption zone 112 or the cooling zone 113, so as to realize the adsorption, desorption and cooling functions of the entire adsorption runner 110.

[0031] Further, the desorption zone 112 is divided into a plurality of sub-desorption zones 114, and the position of each heater 160 corresponds to the position of a sub-desorption zone 114. The heater 160 is used to heat the air passing through the sub-desorption zone 114, and the heating temperatures of the plurality of heaters 160 are different, so as to form a plurality of desorption winds with different temperature distributions. The plurality of desorption winds can pass through the plurality of sub-desorption zones 114 one by one, so as to simultaneously take away the moisture attached to the adsorption runner 110, and then converge together and blow to the indoor, to realize the humidifying function. In this process, since the plurality of desorption winds have different temperature distributions, unnecessary heating of the desorption zone 112 can be prevented, and the situation that the temperature of the desorption zone 112 is too high can be avoided, so as to maintain the relative humidity of the air passing through the desorption zone 112, ensure the humidifying effect and comfort, improve the user experience, reduce the power consumption, reduce the operating cost, and save energy and protect the environment. In addition, since the temperature of the adsorption runner 110 is reduced, the reliability of the adsorption runner 110 can be improved, the degradation can be prevented, the service life of the adsorption runner 110 can be prolonged, and there is no need to set an auxiliary zone for keeping the desorption temperature uniform and a mixing chamber for mixing the desorption wind, which is beneficial to the miniaturization of the dry humidifying device 100.

[0032] In this embodiment, the adsorption zone 111 and the desorption zone 112 are both arranged in a fan shape, the adsorption zone 111 is arranged adjacent to the desorption zone 112, and the area of the adsorption zone 111 is greater than that of the desorption zone 112, so as to facilitate the adsorption of the moisture of the outdoor air by the adsorption runner 110, and facilitate the desorption wind to desorb the moisture attached to the adsorption runner 110 and take it to the indoor, thereby realizing the humidifying function.

[0033] Further, the cooling area 113 is arranged in a fan shape and is adjacent to the adsorption area 111 and the desorption area 112, the area of the adsorption area 111 is greater than that of the cooling area 113, the adsorption area 111, the desorption area 112 and the cooling area 113 are sequentially distributed along the rotation direction of the adsorption runner 110, and the second air duct 130 sequentially passes through the cooling area 113 and the desorption area 112, that is, the second air duct 130 passes through the cooling area 113 from one side of the adsorption runner 110 and passes through the desorption area 112 from the other side of the adsorption runner 110, so that the air in the second air duct 130 passes through the adsorption runner 110 twice.

[0034] In the embodiment, the sub-desorption areas 114 are arranged in a fan shape, and the heating temperatures of the plurality of sub-desorption areas 114 gradually decrease along the rotation direction of the adsorption runner 110. Among the plurality of sub-desorption areas 114, the heating temperature of the sub-desorption area 114 closer to the adsorption area 111 is higher, and the heating temperature of the sub-desorption area 114 closer to the cooling area 113 is lower, so as to ensure the desorption effect while preventing the relative humidity of the air passing through the desorption area 112 from being reduced, thereby ensuring the humidification effect. However, it is not limited thereto. In other embodiments, the heating temperatures of the plurality of sub-desorption areas 114 can gradually increase along the rotation direction of the adsorption runner 110, the heating temperatures of the plurality of sub-desorption areas 114 can first gradually increase and then gradually decrease along the rotation direction of the adsorption runner 110, or the heating temperatures of the plurality of sub-desorption areas 114 can first gradually decrease and then gradually increase along the rotation direction of the adsorption runner 110. The order of the high and low of the heating temperature distribution of the plurality of sub-desorption areas 114 is not specifically limited.

[0035] In the embodiment, the number of the sub-desorption areas 114 and the number of the heaters 160 are both three, the areas of the three sub-desorption areas 114 are the same, each sub-desorption area 114 is used for passing a desorption air, and each heater 160 is used for heating a desorption air. However, it is not limited thereto. In other embodiments, the number of the sub-desorption areas 114 and the number of the heaters 160 can both be four or five, and the areas of the plurality of sub-desorption areas 114 can also be different. The number of the sub-desorption areas 114 and the number of the heaters 160 and the size of the area of the sub-desorption areas 114 are not specifically limited.

[0036] Further, the heating temperature range of the heater 160 is 70-90 degrees Celsius. A reasonable heating temperature can ensure the desorption effect and will not affect the relative humidity of the desorption air. Specifically, the heater 160 is an electric heater 160, so as to realize rapid heating and precise temperature regulation.

[0037] In the embodiment, the second air duct 130 is provided with a plurality of partitions 131 to divide the second air duct 130 into a plurality of heating cavities 132, each of the heaters 160 is installed in one of the heating cavities 132, and the position of each of the heating cavities 132 corresponds to the position of one of the sub-desorption zones 114, so as to realize the functions of fixing and heating of the heaters 160. Specifically, when the outdoor air passes through the cooling zone 113 under the action of the second fan 150, the heaters 160 can heat the air to form desorption air, and then the desorption air passes through the plurality of sub-desorption zones 114 under the action of the second fan 150 to realize the humidification function.

[0038] It is worth noting that the adsorption runner 110 is made of dry moisture-absorbing material, which can quickly adsorb water and quickly desorb under the action of desorption air, and has good moisture absorption and humidification effects.

[0039] In the embodiment, the temperature distribution of the desorption zone 112 is adjusted to prevent the relative humidity of the air passing through the desorption zone 112 from decreasing, thereby ensuring the humidification effect. However, it is not limited to this. In another embodiment, if the temperature distribution of the desorption zone 112 is uniform, the adsorption runner 110 can be controlled to operate intermittently. When the adsorption runner 110 operates, the relative humidity of the air passing through the desorption zone 112 gradually decreases, but when the adsorption runner 110 stops operating, the relative humidity of the air passing through the desorption zone 112 gradually rises, so that the relative humidity can also be maintained in an appropriate range. However, in this way, since the relative humidity is always changing, the comfort will be affected. In another embodiment, if the temperature distribution of the desorption zone 112 is uniform, the air volume of the outlet air can be reduced to reduce the relative humidity of the air passing through the desorption zone 112, thereby ensuring the humidification effect and improving the user experience.

[0040] The dry humidification device 100 provided in the embodiment of the present application includes an adsorption runner 110, a first air duct 120, and a second air duct 130. The adsorption runner 110 is provided with an adsorption zone 111 and a desorption zone 112. The first air duct 120 is in communication with the outdoor air through the adsorption zone 111. The second air duct 130 is in communication with the indoor air through the desorption zone 112. The desorption zone 112 is divided into a plurality of sub-desorption zones 114. The position of each of the heaters 160 corresponds to the position of one of the sub-desorption zones 114. The heaters 160 are used to heat the air passing through the sub-desorption zones 114. The heating temperatures of the plurality of heaters 160 are different. Compared with the prior art, the dry humidification device 100 provided in the present application can maintain the relative humidity of the air passing through the desorption zone 112, ensure the humidification effect, improve the user experience, reduce the power consumption, reduce the operating cost, and save energy and protect the environment.

[0041] Second embodiment

[0042] Please refer to Figure 4 , Figure 5 and Figure 6 ( Figure 4 and Figure 5 ) hollow arrows represent the direction of air flow), the embodiment of the present application provides a dry humidifying device 100, compared with the first embodiment, the difference of the embodiment is that the dry humidifying device 100 further comprises an air duct switching mechanism 170.

[0043] It should be noted that the air duct switching mechanism 170 is installed on the side of the adsorption runner 110 away from the heater 160, and the air duct switching mechanism 170 is used to adjust the area of the adsorption zone 111 and the desorption zone 112. The air duct switching mechanism 170 can increase the area of the adsorption zone 111 and reduce the area of the desorption zone 112, so as to ensure the humidifying effect under the condition that the outdoor temperature is low and the humidifying amount needs to be increased, and only increasing the air volume or increasing the power of the heater 160 cannot ensure the humidifying amount. Specifically, when the air duct switching mechanism 170 increases the area of the adsorption zone 111 and reduces the area of the desorption zone 112, the heating temperature of the desorption zone 112 as a whole is reduced, and the air volume is reduced, so as to enhance the humidifying effect and improve the user experience.

[0044] In the embodiment, the area adjusted by the air duct switching mechanism 170 is the area of a sub-desorption zone 114 close to the adsorption zone 111. When the air duct switching mechanism 170 does not adjust the area of the adsorption zone 111 and the desorption zone 112, the air flow direction in the dry humidifying device 100 is the same as that of the first embodiment; when the air duct switching mechanism 170 switches a sub-desorption zone 114 close to the adsorption zone 111 to the adsorption zone 111, the heater 160 corresponding to the sub-desorption zone 114 is controlled to stop running. At this time, the air passing through the cooling zone 113 in the second air duct 130 is divided into two parts, one part of the air flows along the original path, is heated under the action of the two heaters 160, and passes through the two sub-desorption zones to enter the indoor to realize the humidifying function, and the other part of the air passes through the sub-desorption zone 114 switched to the adsorption zone 111 without being heated, and enters the first air duct 120 along the channel 171 of the air duct switching mechanism 170, and is mixed with the air in the first air duct 120 and then discharged to the outdoor.

[0045] The dry humidifying device 100 described in the embodiment of the present application has the same beneficial effects as the first embodiment, and will not be described here.
