Description

Technical Field

[0001] The invention relates to a deep dehumidification device, in particular to a split variable frequency direct expansion temperature regulating deep dehumidification device, belonging to the technical field of air dehumidification. Background Art

[0002] In a variable frequency direct expansion thermostatic dehumidifier, the refrigerant is first compressed into a high temperature and high pressure gas in the compressor, and then transported to the evaporator through a pipeline. In the evaporator, the refrigerant changes from gas to liquid, and in this process it absorbs the heat of the surrounding air (indoor air, etc.), thereby achieving a cooling effect. When dehumidifying, the humid air passes through the evaporator, and the water vapor in the air condenses into liquid water when it is cooled, and is discharged through the drainage device, thereby reducing the humidity of the air;

[0003] In the prior art, for example, the invention with application number 202011127570.9 discloses a dehumidification device that automatically adjusts the dehumidification intensity according to the air humidity. In order to solve the problem that most traditional air dehumidifiers do not evaluate or detect the air humidity and do not intelligently change the intensity of the dehumidification work according to the air humidity conditions, and cannot achieve a good air humidity balance, the constant air dehumidification intensity of the auxiliary dehumidification device is used to perform a certain evaluation of the moisture content in the air, and the intensity of the main dehumidification device is changed according to the humidity in the air. In addition, the device can perform regular detection of the air humidity within a certain period of time, and intelligently adjust the air dehumidification intensity according to each detection result, thereby better ensuring the air dehumidification effect. It has a high degree of automation and a clear working cycle. It will issue an alarm when the air humidity is too high, which is conducive to users taking corresponding measures in time.

[0004] Similar to the above application, there are still some shortcomings:

[0005] By collecting condensed water and cooperating with the transmission mechanism to automatically control the rotation speed of the fan, the fan continuously rotates back and forth at high and low speeds. Although it can automatically adjust the intensity of dehumidification, the speed of the fan continues to change during use. Even in a high-humidity environment, the fan cannot be guaranteed to run at a constant high speed, which greatly affects the dehumidification rate. In addition, during the use of the device, it is impossible to automatically adjust the temperature when the ambient temperature is low, and the functionality of use is low.

[0006] Therefore, a split variable frequency direct expansion temperature regulating deep dehumidification device is designed to optimize the above problems. Summary of the invention

[0032] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0033] like Figure 1-Figure 8As shown, this embodiment provides a split variable frequency direct expansion temperature regulating deep dehumidification device, including an outdoor unit and a box body 1 installed indoors, a first air inlet 3 is provided on one side of the end of the box body 1, a second air inlet 4 is provided on the other side of the end of the box body 1, a partition 2 is vertically installed at one end of the box body 1 near the first air inlet 3, the first air inlet 3 and the second air inlet 4 are respectively located on both sides of the partition 2, an exhaust port 5 is provided at one end of the box body 1 away from the second air inlet 4, a fan 6 is installed at one end of the box body 1 near the exhaust port 5, and a distance is left between the fan 6 and the end of the partition 2, and the middle position of the box body 1 along the width An evaporator 7 is installed in the direction of degree, and the evaporator 7 passes through the partition 2. The refrigerant compressed in the outdoor unit is connected with the evaporator 7 through a pipeline. A water collecting bin 8 is provided at the bottom of the evaporator 7. One end of the water collecting bin 8 is connected to the outside of the box body 1. A control bin 9 is provided at the bottom of the partition 2 near the first air inlet 3. A frequency converter 10 electrically connected to the fan 6 is installed inside the control bin 9. A rotating control mechanism 11 for controlling the rotation of a knob on the frequency converter 10 is provided inside the water collecting bin 8. An air intake constant adjustment mechanism is provided on one side of the partition 2 near the first air inlet 3 and above the control bin 9, and a temperature control mechanism is provided inside the box body 1.

[0034] Overall working principle: During use, indoor air enters the interior of the box body 1 through the first air inlet 3 and the second air inlet 4. After passing through the evaporator 7, the moisture in the air condenses into water droplets and flows into the water collection bin 8. The presence of the partition 2 in the box body 1 divides the box body 1 into two different areas. When the gas flows in through the first air inlet 3, the air intake volume is less than the air intake volume from the second air inlet 4. In addition, due to the presence of the air volume constant adjustment mechanism, it can ensure that even if the power of the fan 6 changes, the amount of gas entering from the first air inlet 3 remains the same. The device is based on the principle of constant air volume adjustment. The moisture in the constant air intake volume entering from the first air inlet 3 is used as the evaluation standard to determine the air humidity, and the water droplets after the gas entering from the first air inlet 3 is condensed by the evaporator 7 are collected by the rotating control mechanism 11, and are continuously discharged into the water collection bin 8 during the collection process. When the water production rate is greater than the discharge rate, the rotating control mechanism 11 will control the rotation of the knob on the inverter 10 to increase the power of the fan 6, increase the speed of the fan 6, and perform rapid dehumidification. In addition, during the use of the device, if the ambient temperature is low, the temperature control mechanism can be used to increase the temperature of the exhaust gas.

[0035] In this embodiment, the rotation control mechanism 11 includes a collecting bucket 21, a strip drainage groove 22, a return spring 23, a baffle 24, a connecting rod 26, a first rack 28 and a gear 29. The collecting bucket 21 is located below the drain outlet inside the water collecting bin 8, and the collecting bucket 21 is located on the side of the partition 2 close to the first air inlet 3. A strip drainage groove 22 is vertically opened on the side of the collecting bucket 21. A baffle 24 is vertically installed on the inner top of the water collecting bin 8, and the baffle 24 is slidably connected to the collecting bucket 21 and fits on the outer side of the strip drainage groove 22. A return spring 23 is provided on the bottom of the collecting bucket 21 away from the strip drainage groove 22. A connecting rod 26 is fixedly fixed on the side of the collecting bucket 21 close to the return spring 23, and the connecting rod 26 extends to the inside of the control bin 9. A gear 29 is fixed on the adjusting knob at the end of the inverter 10. A first rack 28 meshing with the outer side of the gear 29 is fixed on the end of the connecting rod 26. In the initial state, the first rack 28 is located at the inner top of the control bin 9.

[0036] Local working principle: water droplets entering the housing 1 from the first air inlet 3 and condensed by the evaporator 7 fall into the interior of the collecting bucket 21. In the initial state, the collecting bucket 21 is in contact with the top of the water collecting bin 8, and the strip drainage groove 22 is not completely covered by the baffle 24. When the condensed water falls into the interior of the collecting bucket 21, it will directly flow into the water collecting bin 8 through the strip drainage groove 22. If the amount of water generated by condensation is greater than the water flowing out of the strip drainage groove 22, the collecting bucket 21 will move downward until the amount of condensed water generated is the same as the amount discharged from the drainage groove 22. Only then will the collecting bucket 21 be in a balanced state. When the collecting bucket 21 moves downward, it means that the humidity in the environment is high. In the process of the collecting bucket 21 moving downward, the first rack 28 will be controlled to move downward through the connecting rod 26. The first rack 28 drives the gear 29 to rotate, thereby automatically adjusting the inverter 10, increasing the speed of the fan 6, and accelerating the dehumidification rate.

[0037] In this embodiment, a vertical rod 25 is vertically fixed between the upper and lower ends of the water collecting bin 8. The vertical rod 25 passes through the reset spring 23 and is slidably connected to the side of the collecting bucket 21. A through groove 27 is vertically opened on one side of the water collecting bin 8 close to the control bin 9, and the connecting rod 26 passes through the inside of the through groove 27.

[0038] Partial working principle: When the collecting bucket 21 moves downward, it moves vertically downward along the height direction of the vertical rod 25 to ensure the stability of the collecting bucket 21. When the connecting rod 26 moves downward, it moves vertically inside the through groove 27.

[0039] In this embodiment, the strip-shaped drainage groove 22 is disposed at one end of the collecting hopper 21 , and the bottom end of the strip-shaped drainage groove 22 is an inclined surface, and the bottom end of the inclined surface faces the strip-shaped drainage groove 22 .

[0040] Partial working principle: Due to the inclined design of the bottom end of the collecting bucket 21, the condensed water can be easily collected and discharged.

[0041] In this embodiment, the constant air intake adjustment mechanism includes a rotating rod 32, a wind shield 12 and an angle adjustment assembly 13. The rotating rod 32 is rotatably installed on the side of the partition 2 close to the first air inlet 3, and the other end of the rotating rod 32 is rotatably connected to the side of the box body 1. The wind shield 12 is fixedly installed on the rotating rod 32, and an angle adjustment assembly 13 is provided below the wind shield 12 to control the wind shield 12 to rotate with the rotating rod 32.

[0042] Local working principle: In the initial state, the wind shield 12 is attached to the top of the box body 1 and is in a fully open state. When the speed of the fan 6 increases, the angle adjustment component 13 will control the wind shield 12 to rotate downward along with the rotating rod 32 to reduce the size of the air inlet formed by the partition 2, the wind shield 12, the side of the box body 1 and the control compartment 9, ensuring that the first air inlet 3 can take in a constant air volume.

[0043] In this embodiment, the angle adjustment assembly 13 includes a slide groove 33, a slider 34 and a pull rod 35. The slide groove 33 is opened at the bottom of the wind shield 12 along the length direction of the box body 1. The slider 34 is slidably installed inside the slide groove 33. The bottom of the slider 34 is hingedly installed with a pull rod 35. The pull rod 35 is vertically inserted into the interior of the control compartment 9 and is slidably connected to the control compartment 9. The bottom end of the pull rod 35 is fixed on the first rack 28.

[0044] Local working principle: When the first rack 28 moves downward to adjust the inverter 10, a downward force is applied to the pull rod 35, and the pull rod 35 pulls the slider 34 downward. The slider 34 slides inside the slide groove 33 and drives the windshield 12 to tilt downward.

[0045] In this embodiment, the temperature control mechanism includes an electric heater 14, a bimetallic temperature control switch 15, an adjustable resistor 16 and a contact translation assembly 17. The electric heater 14 is installed at one end of the box body 1 close to the fan 6, the bimetallic temperature control switch 15 is installed at one end of the side of the partition 2 close to the first air inlet 3, and the adjustable resistor 16 is installed inside the control compartment 9. The electric heater 14, the bimetallic temperature control switch 15 and the adjustable resistor 16 are connected in series, and a contact translation assembly 17 is provided on the side of the adjustable resistor 16.

[0046] Local working principle: When the intake air temperature is low, the bimetallic temperature control switch 15 is reset and closed, and the circuit consisting of the electric heater 14, the bimetallic temperature control switch 15 and the adjustable resistor 16 is turned on. At this time, the adjustable resistor 16 is in the maximum resistance state, and the electric heater 14 generates a certain amount of heat to heat the exhaust gas.

[0047] In this embodiment, the contact translation assembly 17 includes a second rack 30 and a fixed block 31. The second rack 30 is vertically slidably arranged inside the control compartment 9 and meshes with the side of the gear 29. The side of the second rack 30 is vertically fixed with a fixed block 31, and the fixed block 31 is connected to the contact on the adjustable resistor 16.

[0048] Local working principle: In the initial state, the second rack 30 is in contact with the bottom end of the control chamber 9 due to its own gravity. When the speed of the fan 6 increases, the first rack 28 drives the rotation of the gear 29, and the gear 29 is meshed with the second rack 30, so the upward movement of the second rack 30 is controlled. In the process of the second rack 30 moving upward, the contact on the adjustable resistor 16 is dragged to slide, thereby reducing the resistance of the adjustable resistor 16. At this time, the current in the circuit will increase, and the electric heater 14 will generate more heat to ensure the heating temperature of the gas during discharge.

[0049] In this embodiment, a filter screen 18 is vertically installed at one end of the box body 1 away from the fan 6, and the filter screens 18 are respectively located on both sides of the partition 2. A sealing cover 19 is hingedly installed on the top of the box body 1 and above the filter screen 18. A locking mechanism 20 for positioning the sealing cover 19 is provided on the top of the box body 1.

[0050] Partial working principle: When external air enters the interior of the box 1, it will first be filtered through the filter 18 and then condensed and dehumidified, which not only improves the functionality of the device, but also prevents dust from adhering to the evaporator 7, ensuring the dehumidification effect.

[0051] In this embodiment, the locking mechanism 20 includes a mounting block 36, a receiving groove 37, a trapezoidal plug block 38, a squeezing spring 39, a cross bar 40 and a pull block 41. The mounting block 36 is fixed to the top of the box body 1. A receiving groove 37 is provided at the bottom of the mounting block 36 close to the sealing cover 19. A trapezoidal plug block 38 is horizontally slidably installed inside the receiving groove 37. A squeezing spring 39 is provided between the end of the trapezoidal plug block 38 and the inner end of the receiving groove 37. A cross bar 40 is fixed to one end of the trapezoidal plug block 38 close to the squeezing spring 39. The cross bar 40 passes through the inside of the squeezing spring 39 and slides out from the end of the mounting block 36. A pull block 41 is fixed to the end of the cross bar 40.

[0052] Partial working principle: During the closing process of the sealing cover 19, the trapezoidal plug block 38 can be directly contacted with the inclined surface thereof, and the trapezoidal plug block 38 can be squeezed into the inside of the receiving groove 37. After the sealing cover 19 is closed, the trapezoidal plug block 38 is reset under the elastic force of the squeezing spring 39, and is pressed on the top of the sealing cover 19 for limiting. When the sealing cover 19 is opened, the pull block 41 drives the cross bar 40 and the trapezoidal plug block 38 to move, and the trapezoidal plug block 38 is pulled into the inside of the receiving groove 37, and then the sealing cover 19 is opened.
