[0041] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment," "in some embodiments," or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0042] Please also refer to Figures 1 to 10 The dehumidifier with oblique air outlet provided by the embodiment of the present invention is now described. Figure 1 、 Figure 2 、 Figure 3 and Figure 5The dehumidifier with oblique air outlet provided by the embodiment of the present invention includes a shell 1, an evaporator 2, a condenser 3, a compressor 4 and a volute fan 5. The shell 1 is provided with an air inlet 11 for introducing moist air from the room and an air outlet 12 for discharging dry air into the room. The air inlet 11 is a mesh-type air outlet or a grille-type air outlet provided on the side of the shell 1. The shell 1 is provided with an external circulation air duct connected to the air inlet 11. The volute fan 5 is arranged inside the shell 1. The centrifugal air duct 511 of the volute fan 5 is connected to the air duct, and the exhaust air duct 512 of the volute fan 5 is connected to the air outlet 12. The evaporator 2 is arranged in the external circulation air duct. The evaporator 2 is used to evaporate the liquid refrigerant to form a gaseous refrigerant, and to reduce the temperature of the air by absorbing heat in the air, so that the moisture in the air is adsorbed on the aluminum foil of the evaporator 2 to reduce the absolute humidity in the air. The condenser 3 is arranged in the external circulation air duct, and the condenser 3 is used to condense the gaseous refrigerant to form a liquid refrigerant, and heat the air processed by the evaporator 2 to reduce the relative humidity in the air. The compressor 4 is arranged in the external circulation air duct, and the compressor 4 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant, so as to provide power for the internal circulation of the refrigerant in the loop formed by the evaporator 2, the compressor 4 and the condenser 3 in series. The volute fan 5 is arranged in the shell 1 and is close to the air outlet 12. The volute fan 5 is used to transport the indoor air to the air outlet 12 through the air inlet 11, and provide power for the external circulation of the indoor air in the loop of the external circulation air duct. It should be noted that, in the dehumidifier, the internal circulation working principle of the dehumidifier constructed by the evaporator 2, the condenser 3 and the compressor 4 is a mature existing technology and will not be elaborated here. Since the air outlet 12 is located on the side of the shell 1 and close to the top of the shell 1, the exhaust duct 512 extends obliquely upward from the center of the shell 1 toward the air outlet 12, so that the dry air treated by the evaporator 2 and the condenser 3 can be discharged obliquely upward into the room through the air outlet 12. Compared with the vertical upward exhaust of the air outlet 12 on the top of the casing, the exhausted dry air can be transmitted to a farther position, which is conducive to promoting the circulation of indoor air and achieving the requirement of quickly reducing indoor humidity. It can also avoid the dry air discharged from the air outlet 12 from blowing directly on people, thereby improving user comfort.

[0043] Please refer to further Figures 1 to 4The dehumidifier with oblique air outlet provided by the embodiment of the present invention is compared with the prior art. By arranging the air outlet 12 on the side of the shell 1 and near the top of the shell 1, an exhaust duct 512 connected to the air outlet 12 is provided at the volute tongue part of the volute fan 5. Since the exhaust duct 512 is arranged to extend obliquely upward from the central position inside the shell 1 toward the air outlet 12, the dry air processed by the evaporator 2 and the condenser 3 can be guided obliquely upward by the exhaust duct 512 and finally discharged obliquely upward into the room through the air outlet 12. Compared with the vertical upward exhaust of the air outlet 12 on the top of the casing, the exhausted dry air can be transmitted to a farther position, which is beneficial to promoting the circulation of indoor air and achieving the requirement of quickly reducing the indoor humidity. It can also avoid the dry air exhausted from the air outlet 12 from directly blowing on people, thereby improving the comfort of users.

[0044] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the external circulation air duct includes a dehumidification chamber 13 that is connected to the air inlet 11 and is used to install the evaporator 2 and the condenser 3, and an installation chamber 14 that is connected to the dehumidification chamber 13 and is used to install the compressor 4. The volute fan 5 is located in the installation chamber 14 and is adjacent to the top of the installation chamber 14. The installation chamber 14 is connected to the air suction port of the volute fan 5. In this embodiment, the installation chamber 14 for installing the compressor 4 is provided in the external circulation air duct loop. Since the installation chamber 14 is respectively connected to the dehumidification chamber 13 and the air suction channel of the volute fan 5, under the action of the volute fan 5, the indoor air is sequentially transported to the air outlet 12 via the air inlet 11, the dehumidification chamber 13, the installation chamber 14, the air suction channel, the centrifugal air duct 511, and the exhaust air duct 512. The air in dehumidification chamber 13, dehumidified by evaporator 2 and condenser 3, cools compressor 4 as it flows through mounting chamber 14. This effectively removes the heat generated by compressor 4, effectively lowering its temperature and preventing the dehumidifier from malfunctioning due to excessively high exhaust pressure and temperature when compressor 4 operates in a high-temperature environment. Furthermore, the heat generated by compressor 4 can be used to reheat the dehumidified air, further reducing the relative humidity in the air and thereby improving the dehumidification efficiency and effectiveness of the dehumidifier.

[0045] Please refer to Figure 2 、 Figure 7 and Figure 8In some embodiments, the volute fan 5 includes a volute body 51 with a centrifugal air duct 511 and an exhaust air duct 512 inside, a centrifugal wind wheel 52 arranged in the centrifugal air duct 511 and a motor for driving the centrifugal wind wheel 52 to work, the motor is arranged on the volute body 51, and the volute body 51 is provided with a first air suction port 513 and a second air suction port 514 connected to the centrifugal air duct 511, the first air suction port 513 and the second air suction port 514 together constitute an air suction channel, and the first air suction port 513 and the second air suction port 514 are respectively connected to the installation cavity 14.

[0046] Please refer to Figure 3 、 Figure 7 and Figure 8 In some embodiments, the first air intake port 513 and the second air intake port 514 are relatively arranged at the two ends of the volute body 51 in the axial direction, and the motor is installed on the side of the volute body 51 with the first air intake port 513, and the air intake area of ​​the first air intake port 513 is larger than the air intake area of ​​the second air intake port 514. Through the above-mentioned structural arrangement, compared with the traditional double-suction volute fan 5 with the same air intake area of ​​the first air intake port 513 and the second air intake port 514 on both sides, due to the increase in the area of ​​the first air intake port 513 on the side of the volute body 51 with the motor, the adverse effects of the reduction in air intake area and increase in wind resistance on one suction side of the volute body 51 due to the installation of the motor are reduced, so that the air intake volume on the side of the volute body 51 with the motor tends to increase, thereby reducing the difference in air intake volume on the two suction sides of the volute body 51, ensuring that the air intake on both sides of the volute body 51 is more balanced, which is conducive to reducing wind noise.

[0047] It can be understood that in some embodiments, in order to reduce wind resistance and wind noise, the exhaust area of ​​the exhaust duct 512 is greater than or equal to the sum of the air inlet area of ​​the first air intake port 513 and the air inlet area of ​​the second air intake port 514, so that the air volume entering from the first air intake port 513 and the second air intake port 514 can be discharged to the air outlet 12 in a timely and rapid manner through the exhaust duct 512.

[0048] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, in order to further reduce wind resistance and wind noise, the diameter of the exhaust duct 512 is greater than or equal to the radius of the centrifugal wind wheel 52, the diameter of the exhaust duct 512 is smaller than the diameter of the centrifugal wind wheel 52, and the axial length of the exhaust duct 512 is greater than or equal to the diameter of the exhaust duct 512.

[0049] Please refer to Figure 1 、 Figure 2 and Figure 3In some embodiments, the dehumidifier with oblique air outlet also includes a water tank 50 arranged at the top of the shell 1, the compressor 4 is located at the bottom of the shell 1, and the volute fan 5 is located between the water tank 50 and the compressor 4, which is conducive to a more compact internal structure layout of the dehumidifier and does not affect the setting size of the top water tank 50.

[0050] Please refer to Figure 1 、 Figure 5 and Figure 6 In some embodiments, the housing 1 further includes a dry shoe chamber 6 and a dry shoe passage 7 connecting the dry shoe chamber 6 with the exhaust duct 512. The housing 1 is also provided with a switch door 8 for opening or closing the inlet 30 of the dry shoe chamber 6, a damper 10 for opening or closing the air outlet 12, and a dry shoe valve 9 for opening or closing the dry shoe passage 7. When the switch door 8 closes the inlet 30 of the dry shoe chamber 6 and the damper 10 is open, the dry shoe valve 9 closes the dry shoe passage 7 due to the negative pressure generated by the volute fan 5 in the exhaust duct 512, and the dehumidifier now operates in dehumidification mode. When the switch door 8 opens the inlet 30 of the shoe drying chamber 6 and the damper 10 is in the closed state, the shoe drying valve 9 opens the shoe drying passage 7 under the action of the wind pressure generated by the volute fan 5 in the exhaust duct 512. At this time, the exhaust duct 512 is connected to the shoe drying chamber 6 through the shoe drying passage 7, and the volute fan 5 can blow dry air into the shoe drying passage 7 to dry the shoes in the shoe drying chamber 6 with the dry air.

[0051] It can be understood that in some embodiments, in order to meet the practical needs of users to reasonably adjust the blowing angle and blowing air volume according to usage requirements, the damper 10 is an air outlet guide blade that can adjust the air outlet size and air outlet angle.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the angle between the center line of the exhaust duct 512 and the horizontal plane is 45° to 60°, which can enable the dry air treated by the evaporator 2 and the condenser 3 to be finally discharged obliquely upward into the room through the air outlet 12 under the oblique upward guidance of the exhaust duct 512, which is beneficial for transmitting the exhausted dry air to a farther location, promoting the circulation of indoor air, achieving the requirement of quickly reducing indoor humidity, and avoiding the dry air discharged from the air outlet 12 from blowing directly on people, thereby improving user comfort.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 9 and Figure 10In some embodiments, the dehumidifier with oblique air outlet further includes a water receiving tray 60 provided at the bottom of the evaporator 2, a water tank 50 for storing condensed water, and a water pump 20 for transferring the condensed water in the water receiving tray 60 to the water tank 50. The water tank 50 is provided at the top of the housing 1, and the water pump 20 is placed in the water receiving tray 60. The water pump 20 is connected to the water tank 50 through a water pipe. In order to facilitate the movement of the dehumidifier, four casters 40 are also provided at the bottom of the housing 1.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
