Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidification equipment, and specifically relates to a dehumidifier capable of achieving drying inside a machine body. Background Art

[0002] The dehumidifier generates a large amount of condensed water during the dehumidification process. Most of the condensed water is received by the water receiving device and discharged to the outside of the dehumidifier or discharged into the water tank of the dehumidifier. At the end of dehumidification, users generally only pour out the condensed water in the dehumidifier water tank. However, some condensed water will still remain in the heat exchanger and water receiving device in the dehumidifier. Since the evaporator and the water receiving tray are enclosed in the dehumidifier casing, they cannot be handled manually. In particular, the water in the evaporator is not easy to evaporate. The long-term retention of condensed water will breed bacteria and produce a musty smell. When the dehumidifier is turned on again, the dehumidifier will emit musty smell and mold into the air, affecting the user experience and physical health.

[0091] The second heating chamber 491 is provided on the outer side of the condensed water temporary storage portion 49 to avoid increasing the thickness of the water receiving device 4, thereby making more reasonable use of the internal space of the dehumidifier.

[0092] The outer drain port 41 is higher than the inner drain port, which can ensure the emptying of the condensed water temporary storage portion 49.

[0093] In some embodiments, the inner drain port is located at the bottom surface of the condensed water temporary storage portion 49 , and the outer drain port 41 is located at the side surface of the condensed water temporary storage portion 49 .

[0094] like Figure 9-12 As shown, a drainage through hole 11 is provided on the housing 1.

[0095] The water receiving device 4 is provided with an external drain port 41 , which is connected to the water receiving device 4 to drain the condensed water received in the water receiving device 4 .

[0096] The drainage through hole 11 corresponds to the external drainage port 41 of the water receiving device 4 .

[0097] The drainage through hole 11 is used to expose the external drainage port 41 to facilitate the external drainage port 41 to be connected to an external drainage pipe.

[0098] In some embodiments, the external drain port 41 is completely located inside the shell 1 , and the external drain pipe passes through the drain through hole 11 and is connected to the external drain port 41 .

[0099] In some embodiments, the outer drain port 41 is partially located in the drain through hole 11 and does not protrude from the drain through hole 11 , and the external drain pipe and the outer drain port 41 are connected in the drain through hole 11 .

[0100] In some embodiments, the external drain port 41 is partially located in the drain through hole 11 and protrudes out of the drain through hole 11 , and the external drain pipe and the external drain port 41 are connected at the outside of the shell 1 .

[0101] An inner recess 12 is provided on the housing 1 , and the drainage through hole 11 is located at the inner recess 12 .

[0102] The housing 1 is also provided with an air inlet and an air outlet.

[0103] The air inlet is located on the side of the housing 1 to achieve side air intake of the dehumidifier.

[0104] In some embodiments, the air inlet is located on the front side of the housing 1 .

[0105] In some embodiments, the air inlet is located on the rear side of the housing 1 .

[0106] The air inlet allows air outside the dehumidifier to enter the dehumidifier.

[0107] An air inlet grille is provided at the air inlet to provide air inlet protection.

[0108] In some embodiments, a filtering device is provided at the air inlet.

[0122] When the drain cover 5 is closed, the outer surface of the drain cover 5 is flush with the outer surface of the shell 1, forming an integrated appearance.

[0123] When the drain cover 5 is opened, the external drain port 41 can be connected to a pipeline for external drainage.

[0124] In addition, when the heating body of the dehumidifier works to dry the inside of the dehumidifier, the drain cover 5 can be opened to connect with the outside of the dehumidifier through the external drain port 41, and part of the water vapor generated at the water receiving device 4 can be discharged from the dehumidifier through the external drain port 41 to speed up the discharge of moisture in the dehumidifier.

[0125] Specifically, Fig.12 As shown, the drain cover 5 includes a cover body 51 , a connecting arm 52 and a rotating shaft 53 .

[0126] The cover body 51 is a cover plate whose size matches the inner recess 12. When the drain cover 5 is in a closed state, the shape of the cover body 51 matches the shape of the shell 1. The cover body 51 is connected to the shell 1 and is integrated with it in appearance, thereby realizing the integrity of the dehumidifier appearance.

[0127] The cover 51 is always located outside the housing 1 .

[0128] The connecting arm 52 is connected to the cover body 51 .

[0129] In order to prevent the connection arm 52 from affecting the appearance of the cover body 51 , the connection arm 52 is connected to the inner side of the cover body 51 .

[0130] The rotating shaft 53 is located on the connecting arm 52 .

[0131] The rotating shaft 53 is always located inside the housing 1 , and the connecting arm 52 is used to connect the cover 51 and the rotating shaft 53 .

[0132] One end of the connecting arm 52 is connected to the cover body 51 , and the other end is connected to the rotating shaft 53 .

[0133] like Fig.11As shown, a through hole 13 for the connecting arm 52 to pass through is opened on the shell 1. The through hole 13 is large enough for the connecting arm 52 to pass through, and can provide a movable space for the connecting arm 52 during the rotation of the drain cover 5.

[0134] The movement is a structural component located in the housing 1 , and is generally mounted on the base 2 .

[0135] In some embodiments, the core includes an inner shell located on the support base 3 and installed on the support base 3, and a fan cover shell installed on the inner shell, and the inner shell and the fan cover shell form a fan installation space.

[0136] like Fig.10 , 11 As shown, the dehumidifier core is provided with a first card slot 42 at a position opposite to the housing 1, and the core includes a water receiving device 4. In some embodiments, the water receiving device 4 is provided with a first card slot 42 at a position opposite to the housing 1, and the housing 1 is provided with a second card slot 14 at a position opposite to the water receiving device 4, and the rotating shaft 53 is rotatably mounted in the first card slot 42 and the second card slot 14, and the drainage through hole 11 of the housing 1 is close to the water receiving device 4.

[0137] In some embodiments, a first slot 42 is provided at a portion of the movement support seat 3 opposite to the housing 1 , the drainage hole 11 of the housing 1 is provided close to the support seat 3 , and an external drainage port 41 of the water receiving device 4 extends to the drainage hole 11 .

[0138] In some embodiments, other components of the movement, such as an inner shell, a fan cover, etc., are provided with a second slot 14 at a position opposite to the shell 1, and the drainage hole 11 of the shell 1 is arranged close to other components of the movement (such as an inner shell, a fan cover, etc.), and the external drainage port 41 of the water receiving device 4 extends to the drainage hole 11.

[0139] When assembling the dehumidifier, the water receiving device 4 is installed. When the housing 1 is installed on the movement, the connecting arm 52 and the rotating shaft 53 of the drain cover 5 are passed through the through hole 13 of the housing 1, the rotating shaft 53 is placed at the second slot 14, the housing 1 is placed in place, the rotating shaft 53 enters the first slot 42, and then the housing 1 is fixed. The assembly of the movement and the housing 1 is completed, that is, the assembly of the drain cover 5 is completed simultaneously. There is no need to assemble the drain cover 5 and the housing 1 separately, which avoids the problem of assembly difficulty and damage to the drain cover in the prior art that the drain cover needs to be deformed before it can be assembled with the shaft on the housing.

[0140] The assembly method of the rotating shaft 53 and the first clamping groove 42 and the second clamping groove 14 does not require extrusion and deformation, and the length of the rotating shaft 53 can be further increased to ensure the stability of the assembly of the drain cover 5 and the housing 1 and prevent the drain cover 5 from falling off.

[0141] In some embodiments, the first card slot 42 and the second card slot 14 are arranged opposite to each other. Furthermore, the first card slot 42 and the second card slot 14 are directly opposite to each other, that is, the first card slot 42 and the second card slot 14 are located on the same vertical plane of the rotating shaft.
