Description

Technical Field

[0001] This invention relates to the field of dehumidification equipment technology, and more specifically, to a dehumidifier. Background Technology

[0002] A composite dehumidifier that combines rotary dehumidification and dual-electrode (evaporator and condenser) dehumidification typically places the rotary dehumidification module between the evaporator and condenser. This allows the air to first pass through the evaporator to condense water, and then pass through the rotary dehumidifier to further extract moisture, thus achieving a better dehumidification effect.

[0003] However, when the rotary dehumidification module is running, the electric heating box generates a high temperature, and the gap between it and the condenser is small, resulting in excessively high local temperature of the condenser, which affects the heat dissipation of the condenser and reduces the overall dehumidification effect. Summary of the Invention

[0004] The main objective of this invention is to provide a dehumidifier that solves the problem of excessively high local temperatures in the condenser caused by the electric heating box in existing dehumidifiers.

[0005] To achieve the above objectives, the present invention provides a dehumidifier, including an evaporator, a water tray, and a rotary dehumidification assembly. The water tray is used to receive condensate generated by the evaporator and the rotary dehumidification assembly. The rotary dehumidification assembly includes a rotary disc and a heating element for heating the rotary disc. The dehumidifier further includes a water-dispensing element, at least a portion of which is disposed within the water tray. The water-dispensing element is rotatably disposed to dispense condensate from the water tray onto the heating element.

[0006] Furthermore, the dehumidifier also includes: a drive unit having a first output end, the first output end being connected to a water-spraying component so that the first output end drives the water-spraying component to rotate.

[0007] Furthermore, the water-spraying component is a flywheel.

[0008] Furthermore, the heating component includes a heating box and a heating element disposed within the heating box; the water-spraying component sprays condensate from the water tray onto the heating box; the rotary dehumidification assembly also includes a kettle, an air duct, and a fan blade; the kettle is disposed between the evaporator and the rotary disc, with the kettle's air inlet facing the rotary disc; the first air inlet of the air duct is connected to the kettle, and the first air outlet of the air duct is connected to the second air inlet of the heating box; the fan blade is rotatably disposed within the air duct; the second air outlet of the heating box is facing the rotary disc; the driving component has a second output end, which rotates synchronously with the first output end, and the second output end passes through the air duct wall and connects to the fan blade, so that the second output end drives the fan blade to rotate.

[0009] Furthermore, the drive unit is mounted on the duct wall and located on the outside of the duct.

[0010] Furthermore, the dehumidifier also includes: a controller; a liquid level detection component, which is connected to the controller in communication. The liquid level detection component is used to detect the height of the liquid level in the water receiving tray. When the liquid level detection component detects that the liquid level in the water receiving tray has reached the preset height, the controller controls the rotary dehumidification component to start working.

[0011] Furthermore, the liquid level detection component includes a float and a liquid level switch. The float is set inside the water receiving tray. The detection head of the liquid level switch is used to detect the float. When the detection head of the liquid level switch detects the float, the liquid level in the water receiving tray reaches a preset height.

[0012] Furthermore, the water receiving tray is equipped with a placement slot for placing the float, and the placement slot is connected to the space inside the water receiving tray.

[0013] Furthermore, the dehumidifier also includes a condenser having a notch, and a heating element inserted into the notch so that the condenser is arranged around the heating element.

[0014] Furthermore, a first drainage rib is provided on the side wall of the water receiving tray, which is used to guide the splashed condensate back into the water receiving tray.

[0015] Furthermore, the dehumidifier also includes a water baffle, which is connected to the water tray and covers the heating element and the water spraying element to prevent splashing condensate.

[0016] Furthermore, a second drainage rib is provided on the inner wall of the water baffle, which is used to guide the splashed condensate back into the water receiving pan.

[0017] Furthermore, the dehumidifier also includes: a controller; a temperature sensor, which is installed on the heating box of the heating component. The temperature sensor is used to detect the temperature of the heating box. The temperature sensor is connected to the controller. When the temperature sensor detects that the temperature of the heating box is greater than the preset limit temperature, the controller controls the rotary dehumidification component to stop working.

The water receiving tray is used to receive condensate generated by the evaporator and the rotary dehumidification assembly. The rotary dehumidification assembly includes a rotary disc and a heating component for heating the rotary disc. At least a portion of the water spraying component is disposed within the water receiving tray and is rotatably disposed to spray the condensate in the water receiving tray onto the heating component. In this way, the condensate can cool the heating component, reducing the surface temperature of the heating component. Therefore, the heating component will not transfer heat to other components, thereby solving the problem of excessively high local condenser temperature caused by the electric heating box in existing dehumidifiers.

[0033] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] This invention provides a dehumidifier; please refer to [the relevant documentation]. Figures 1 to 10 The dehumidifier includes an evaporator 10, a water tray 20, and a rotary dehumidifier assembly 30. The water tray 20 is used to receive condensate generated by the evaporator 10 and the rotary dehumidifier assembly 30. The rotary dehumidifier assembly 30 includes a rotary disc 31 and a heating element 32 for heating the rotary disc 31. The dehumidifier also includes a water-spraying element 40, at least a portion of which is disposed within the water tray 20. The water-spraying element 40 is rotatably disposed to spray the condensate in the water tray 20 onto the heating element 32.

[0036] The dehumidifier of the present invention includes an evaporator 10, a water receiving tray 20, a rotary dehumidification assembly 30, and a water spraying component 40. The water receiving tray 20 is used to receive condensate generated by the evaporator 10 and the rotary dehumidification assembly 30. The rotary dehumidification assembly 30 includes a rotary disc 31 and a heating component 32 for heating the rotary disc 31. At least a portion of the water spraying component 40 is disposed within the water receiving tray 20. The water spraying component 40 is rotatably disposed to spray the condensate in the water receiving tray 20 onto the heating component 32. In this way, the condensate can cool the heating component 32, reducing the surface temperature of the heating component 32. Therefore, the heating component 32 will not transfer heat to other components. Specifically, the heating component 32 will not transfer heat to the condenser, thereby solving the problem of excessively high local temperature of the condenser caused by the electric heating box in the prior art dehumidifier, ensuring the heat dissipation effect of the condenser, and thus ensuring the dehumidification effect.

[0037] In this embodiment, the dehumidifier further includes a drive unit 50 having a first output end 51, which is connected to a water-spraying component 40 so that the first output end 51 drives the water-spraying component 40 to rotate. The first output end 51 of the drive unit 50 provides rotational power to the water-spraying component 40 so that the water-spraying component 40 sprays condensate in the water receiving tray 20 onto the heating component 32.

[0038] Optionally, the water-spraying component 40 is a flywheel. Specifically, the edge of the flywheel is provided with multiple teeth spaced apart along the circumference of the flywheel, and each tooth protrudes from the flywheel to drive a larger area of ​​condensate and enhance the water cooling effect.

[0039] In this embodiment, the heating component 32 includes a heating box 33 and a heating element disposed within the heating box 33. The water-spraying component 40 sprays condensate from the water tray 20 onto the heating box 33. The rotary dehumidification assembly 30 also includes a kettle 34, an air duct 35, and a fan blade 36. The kettle 34 is disposed between the evaporator 10 and the rotary disc 31. The air inlet of the kettle 34 is opposite to the rotary disc 31. The first air inlet of the air duct 35 is connected to the kettle 34, and the first air outlet of the air duct 35 is connected to the second air inlet of the heating box 33. The fan blade 36 is rotatably disposed within the air duct 35. The second air outlet of the heating box 33 is opposite to the rotary disc 31. The driving component 50 has a second output end 52, which rotates synchronously with the first output end 51. The second output end 52 passes through the air duct wall of the air duct 35 and is connected to the fan blade 36, so that the second output end 52 drives the fan blade 36 to rotate. In this way, the water-spraying component 40 and the fan blade 36 share the drive component 50, without adding a new drive component, thus saving costs.

[0040] In practical implementation, the second output end 52 of the drive component 50 drives the fan blade 36 to rotate, thereby driving the gas circulation inside the rotary dehumidification assembly 30. The water vapor driven by the rotation of the fan blade 36 circulates sequentially through the kettle 34, the air duct 35, the heating component 32, and the rotary disc 31. Figure 4 As shown by the dashed line in the image.

[0041] In practice, the kettle 34 is close to the evaporator 10, where the temperature is lower. Water vapor enters the kettle 34 and condenses into water, which eventually flows into the water collection tray 20 for accumulation.

[0042] Specifically, the drive unit 50 is a dual-shaft extension motor.

[0043] In this embodiment, the drive unit 50 is disposed on the wall of the air duct and located outside the air duct 35. This arrangement does not affect the passage of water vapor through the air duct 35 and makes reasonable use of the space between the rotary dehumidifier assembly 30 and the water receiving tray 20.

[0044] In this embodiment, the dehumidifier further includes: a controller; and a liquid level detection component 60, which is communicatively connected to the controller. The liquid level detection component 60 is used to detect the height of the liquid level in the water receiving tray 20. When the liquid level detection component detects that the liquid level in the water receiving tray 20 reaches a preset height, the controller controls the rotary dehumidification component 30 to start working. In this way, when the rotary dehumidification component 30 is working, the liquid level in the water receiving tray 20 can ensure that the water spraying component 40 can spray condensate onto the heating component 32 to cool the heating component 32.

[0045] In this embodiment, the liquid level detection component 60 includes a float 61 and a liquid level switch 62. The float 61 is disposed in the water receiving tray 20. The detection head of the liquid level switch 62 is used to detect the float 61. When the detection head of the liquid level switch 62 detects the float 61, the liquid level in the water receiving tray 20 reaches a preset height.

[0046] In practice, the cooperation between float 61 and level switch 62 ensures that when the liquid level in the water receiving tray 20 reaches the preset height, the controller can detect the signal that the preset height has been reached.

[0047] In this embodiment, the water receiving tray 20 is provided with a placement groove 21 for placing the float 61, and the placement groove 21 is connected to the space inside the water receiving tray 20. In this way, the condensate in the water receiving tray 20 can make the float 61 in the placement groove 21 float up, so that the level switch 62 can detect the float 61 when it floats to a preset height.

[0048] Specifically, the placement tank 21 and the water pumping component 40 are located on opposite sides of the heating component 32.

[0049] In this embodiment, the dehumidifier further includes a condenser 70 with a notch 71, and a heating element 32 inserted into the notch 71 so that the condenser 70 is arranged around the heating element 32. This arrangement avoids an excessively large contact area between the heating element 32 and the condenser 70, thereby reducing the impact on the temperature of the condenser 70.

[0050] Specifically, notch 71 forms a first end face and a second end face on condenser 70. The first end face and the second end face are inclined to each other. The first end face is opposite to the heating element 32, and the second end face is opposite to the heating element 32.

[0051] Specifically, the kettle 34 and the rotating disc 31 are positioned between the evaporator 10 and the condenser 70.

[0052] In this embodiment, a first drainage rib 22 is provided on the side wall of the water receiving tray 20. The first drainage rib 22 is used to guide the splashed condensate back into the water receiving tray 20. This allows the condensate to be reused.

[0053] Optionally, at least two first drainage ribs 22 are provided on the side wall of the water receiving tray 20. This arrangement ensures that water droplets splashing onto the inner wall of the water receiving tray 20 will flow into the water receiving tray along the first drainage ribs.

[0054] Optionally, the water-spraying component 40 is provided with first drainage ribs 22 on both the left and right sides, wherein the left and right sides of the water-spraying component 40 are... Figure 9 The water droplets splashing onto the inner wall of the water receiving tray 20 will flow into the water receiving tray along the first guide rib.

[0055] Specifically, the water receiving tray 20 includes a water storage tank 23, an inclined surface 24, and a drain outlet 25. The inclined surface 24 is inclined relative to the bottom surface of the water storage tank 23 and to the horizontal plane. The inclined surface 24 has a first end and a second end that are opposite to each other along its extension direction. The first end of the inclined surface 24 is connected to the bottom surface of the water storage tank 23, and the second end of the inclined surface 24 is higher than the first end of the inclined surface 24. After the dehumidifier is started, the water condensed on the evaporator 10 flows into the water storage tank 23 along the inclined surface 24. The drain outlet 25 is provided on the inclined surface 24 to drain the condensate in the water receiving tray 20. The placement groove 21, the water pumping component 40, and the first drainage rib 22 are all located inside the water storage tank 23.

[0056] In specific implementation, the drain outlet 25 is set to a height higher than the preset height of the liquid level in the water receiving tray; optionally, the difference between the drain outlet 25 and the preset height of the liquid level in the water receiving tray is greater than or equal to 5mm, so as to satisfy the condition that the liquid level in the water receiving tray is higher than the lowest point of the water pumping component, so that the water pumping component can drive the condensate to the heating box.

[0057] In this embodiment, the dehumidifier further includes a water baffle 80, which is connected to the water receiving tray 20. The water baffle 80 covers the heating element 32 and the water spraying element 40 to prevent splashing condensate.

[0058] Specifically, the level switch 62 is installed on the inner wall of the baffle cover 80.

[0059] In this embodiment, a second drainage rib 81 is provided on the inner wall of the water baffle cover 80. The second drainage rib 81 is used to guide the splashed condensate back into the water receiving pan 20. This allows the condensate to be reused.

[0060] Specifically, the first guide rib 22 is positioned below the water-spraying component 40, while the second guide rib 81 is positioned above the water-spraying component 40. This arrangement ensures that water droplets splashing onto the water baffle and the inner wall of the water receiving tray will flow into the water receiving tray along the guide ribs.

[0061] Optionally, at least two second drainage ribs 81 are provided on the inner wall of the water baffle 80. This arrangement ensures that water droplets splashing onto the inner wall of the water baffle will flow into the water receiving tray along the second drainage ribs.

[0062] Optionally, a second guide rib 81 is provided on both the left and right sides of the water-spraying component 40, wherein the left and right sides of the water-spraying component 40 are... Figure 10 The water flow is directed left and right. This design ensures that water droplets splashing onto the inner wall of the baffle cover will flow into the water collection tray along the second guide rib. In this embodiment, the dehumidifier also includes: a controller; and a temperature sensor, which is installed on the heating box 33 of the heating component 32. The temperature sensor is used to detect the temperature of the heating box 33 and is communicatively connected to the controller. When the temperature sensor detects that the temperature of the heating box 33 is greater than a preset limit temperature, the controller controls the rotary dehumidification assembly 30 to stop working. This avoids damage to the dehumidifier caused by the rotary dehumidification assembly 30 continuing to work when the temperature of the heating box 33 is overheated.

[0063] In practice, the temperature sensor reads the temperature once per minute. When the temperature sensor detects that the temperature of the heating box 33 is lower than the preset limit temperature and the liquid level detection component 60 detects that the liquid level in the water receiving tray 20 has reached the preset height, the rotary dehumidification component 30 continues to work. During the operation of the dehumidifier, the user can press the power off button at any time, and the rotary dehumidification component 30 will stop operating.

[0064] Optionally, the heating element 32 is an electric heating element.

[0065] Specifically, the evaporator 10, the rotary dehumidifier assembly 30, and the condenser 70 are all mounted on the water receiving tray 20.

[0066] Specifically, the dehumidifier of this application is a composite dehumidifier with a rotary dehumidification component and a dual-phase dehumidification system. In practice, after the user turns on the dehumidifier, the compressor of the composite dehumidifier starts working, while the rotary dehumidification component does not work. Ordinary dual-phase dehumidification is performed first. When the condensate in the water tank of the drip tray reaches the preset height, the level switch is turned on, the rotary dehumidification component works, and the water pumping component works at the same time to cool the heating box. During the operation of the rotary dehumidification component, the temperature sensor monitors the temperature T of the heating box. When T>T0 (T0 is the preset limit temperature), the rotary dehumidification component stops operating.

[0067] The present invention has the following beneficial effects:

[0068] The drive unit 50 uses a dual-shaft extension motor, with the water-spraying component 40 and the fan blades 36 of the rotary dehumidification assembly 30 installed on both sides respectively. When the rotary dehumidification assembly 30 is activated, the water-spraying component 40 works, spraying the condensate collected in the water tray 20 onto the heating box 33, which plays a role in condensation and heat dissipation. The drive unit 50 is shared with the fan blades 36, without the need for an additional motor, saving costs. A condenser 70 with a notch 71 is used to reduce the contact area between the condenser 70 and the heating box 33, thereby reducing the impact of the heating box 33 on the temperature of the condenser 70. The corners of the water tray 20 and the water baffle 80 are provided with a first drainage rib 22 and a second drainage rib 81 to guide the water droplets thrown to the corners by the water-spraying component 40 back to the water tray 20. With the help of the control program, under suitable conditions, the rotary dehumidification assembly 30 is turned on for dehumidification, reducing power consumption and improving energy efficiency.

[0069] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0070] The dehumidifier of the present invention includes an evaporator 10, a water receiving tray 20, a rotary dehumidification assembly 30, and a water spraying component 40. The water receiving tray 20 is used to receive condensate generated by the evaporator 10 and the rotary dehumidification assembly 30. The rotary dehumidification assembly 30 includes a rotary disc 31 and a heating component 32 for heating the rotary disc 31. At least a portion of the water spraying component 40 is disposed in the water receiving tray 20. The water spraying component 40 is rotatably disposed to spray the condensate in the water receiving tray 20 onto the heating component 32. In this way, the condensate can cool the heating component 32, thereby reducing the surface temperature of the heating component 32. Therefore, the heating component 32 will not transfer heat to other components, thus solving the problem of excessively high local temperature of the condenser caused by the electric heating box in the prior art dehumidifier.
