DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figures 1 to 5 shown.

[0030] A humidifying device for a duct type indoor unit comprises a humidifying sheet assembly 3 and a water tray assembly 2.

[0031] The water tray assembly 2 includes an upper water tray 22 and a lower water tray 24. The upper water tray 22 is in the shape of a box with an open upper end. The lower water tray 24 is in the shape of a rectangular box with an open upper end and one side, similar to the shape of a "dustpan". The height of the upper water tray 22 is less than the depth of the lower water tray 24, so that it can be placed in the lower water tray 24 and connected to the lower water tray 24 through a bracket 123. The bracket 123 is a sheet metal part, which can be a curved edge shape, placed inside the lower water tray 24, with its lower end connected to the bottom of the lower water tray 24, and its upper end connected to the end of the upper water tray 22, so that the installation of the upper water tray 22 is more convenient and stable. The humidifying sheet assembly 3 is placed in the upper water tray 22. At the same time, the upper water tray 22 is provided with a water inlet pipe 5. The water inlet pipe 5 is connected to an external water source, such as tap water, so as to inject water into the upper water tray 22. Preferably, the corners of the upper end of the upper water tray 22 are respectively provided with overflow holes 21 that penetrate inside and outside, so that excess water can flow into the lower water tray 24 from the overflow holes 21 to avoid overflow.

[0032] The humidifying sheet assembly 3 includes a plurality of humidifying sheets 31. The humidifying sheet 31 can be made of composite fiber and has strong water absorption. Each humidifying sheet 31 has the same shape, which is a T-shaped thin sheet, and a downward protrusion 37 is provided at its right end. The end of the protrusion 37 is pointed, which is convenient for water to flow along this end. A dividing groove 36 is provided in the middle of the humidifying sheet 31. The dividing groove 36 is an obtuse V-shape, vertically arranged, and the opening is toward the right side of the humidifying sheet, so that excess water on the humidifying sheet can flow from the left side of the dividing groove 36 to the right side thereof, and then flow out of the humidifying sheet along the protrusion 37. Preferably, the angle of the dividing groove 36 can be 120-130°. A connecting groove 34 is provided at the concave portion on the left side of the humidifying sheet 31. The connecting groove 34 is a flat rectangular shape, which can be snapped onto the long strip-shaped connecting rod 32 so that the humidifying sheets 31 are arranged vertically. The two ends of the connecting rod 32 are fixed to the two ends of the upper water tray 22, so that the lower part of the humidifying sheet 31 is placed in the upper water tray 22, and the protrusion 37 is located outside the upper water tray 22 and points to the lower water tray 24, so that the humidifying sheet 31 can absorb the water in the upper water tray 22 for humidification. At the same time, the excess unevaporated water can flow out from the protrusion 37 to the lower water tray 24, so that the impurities on the humidifying sheet are taken away with the water flow, ensuring the clean water quality in the upper water tray.

[0033] Furthermore, the left side, right side and lower end of the humidifying sheet 31 are respectively provided with fixing grooves 35, and the fixing grooves 35 can be respectively clamped on the three fixing rods 33. The fixing rods 33 are serrated, so that each humidifying sheet 31 can be clamped into the tooth groove, ensuring that the humidifying sheets are parallel to each other and evenly spaced. The cross-sections of the fixing grooves 35 and the fixing rods 33 are the same in shape, both of which are flat rectangular, so that the two can be conveniently connected.

[0034] The present invention further includes a guide plate 26. The guide plate 26 is in the shape of a long strip, one long side of which is connected to the lower edge of the open side of the lower water tray 24, and is inclined downwardly of the lower water tray 24, and overlapped on the water receiving box 9 of the indoor unit 8, so that the accumulated water in the lower water tray 24 can flow into the water receiving box 9 along the guide plate 26, avoiding overflow and affecting normal use.

[0035] The present invention also includes an air guide plate 4. The cross section of the air guide plate 4 is an obtuse V-shape, and its length is equivalent to the open side of the lower water tray 24, so that the upper side wall of the air guide plate 4 is installed on the open side of the lower water tray 24, and the lower side wall is suspended in the front and upper part of the guide plate 26, which can ensure that the air outlet of the indoor unit blows along the air guide plate 4 to the humidifying sheet assembly 3, while avoiding blowing directly onto the guide plate 26 to affect the normal flow of water. Preferably, the angle of the air guide plate 4 can be 135-150°.

[0036] The water inlet pipe 5 is provided with a float switch assembly 6 to control the water inlet. The float switch assembly 6 is installed in the upper water tray 22, and is located at both ends of the upper water tray 22 together with the humidifying sheet assembly 3. Correspondingly, the upper side wall of the air guide plate 4 is stepped, with its lower end being on the same side as the humidifying sheet assembly 3, and its upper end being on the same side as the float switch assembly 6, so that the air outlet can be ensured to blow toward the humidifying sheet assembly 3, and the float switch assembly 6 can be shielded by the air guide plate 4 to avoid being affected by the air outlet.

[0037] The present invention also includes a shell 1. The shell 1 is formed by connecting a bottom plate 14, a top plate 12, a side plate 13 and a front panel 11, and is connected to the casing of the indoor unit. The front panel 11 is provided with an opening corresponding to the air outlet of the indoor unit for the outlet air to pass through. The lower water tray 24 is installed on the bottom plate 14 so that the opening corresponds to the humidifying sheet assembly 3 so that the outlet air is humidified by passing through the humidifying sheet assembly 3. The shell 1 is connected to the casing of the indoor unit 8, which is convenient for installation and maintenance, and can be beneficial to the modification of the existing indoor unit. Preferably, the top plate and the side plates can be made into one piece and made of sheet metal to simplify the process and improve the strength.

[0038] Furthermore, it also includes a water inlet sealing plate 7. The water inlet sealing plate 7 is in the shape of a short plate, the middle of which is connected to the right end of the lower water tray 24, and the bottom of which is connected to the bottom plate 14. At the same time, the left end of the lower water tray 24 is connected to the bottom plate 14 through a bracket II25, so that the bottom of the lower water tray 24 is raised so that the guide plate 26 is downwardly overlapped on the water receiving box 9 of the indoor unit 8. The water inlet pipe 5 is installed on the water inlet sealing plate 7, one end of which is connected to the float switch assembly 6, and the other end is connected to an external water source, and the water inlet can be automatically controlled through the float switch assembly 6.

[0039] The float switch assembly 6 can be made of Fuji Seiko C-0200105. The bracket II25 is a sheet metal part and can be designed into a suitable shape and size as required.

[0040] The present invention arranges the humidifying sheet assembly in the water tray assembly, and injects water into the water tray through the water inlet pipe, so that the humidifying sheet assembly absorbs moisture. Then, the outer shell is connected to the indoor unit casing, so that the humidifying sheet assembly is arranged at the air outlet of the indoor unit, thereby effectively adjusting the humidity of the air outlet of the indoor unit and improving the user comfort. At the same time, the present invention can be directly installed on the existing ordinary duct type indoor unit, reducing the modification cost and being suitable for promotion.

[0041] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
