Description

Technical Field

[0001] The present invention relates to air conditioning technology, and in particular to a multi-mode controlled dehumidifier and a control method thereof. Background Art

[0002] A multi-mode dehumidifier is an air conditioning device used to regulate air temperature and humidity. Its operating principle is to remove heat from the surrounding air through the evaporator through the evaporation of liquid refrigerant. As the refrigerant evaporates, the temperature of the evaporator drops, and the temperature of the air passing through the evaporator also drops. Consequently, as the temperature around the evaporator drops, moisture in the air condenses and forms dew on the surface of the evaporator. The dehumidified air is then discharged into the room, thereby reducing the humidity in the room. Furthermore, the evaporator and condenser of existing multi-mode dehumidifiers are often arranged side by side. Air first passes through the evaporator, where moisture condenses into liquid water. The air then flows through the evaporator's fins into a water pan, where its temperature drops, before passing through the condenser to absorb heat. This gives existing multi-mode dehumidifiers the characteristics of a heat pump, allowing them to both cool and dehumidify the air using the evaporator's cooling capacity and heat the reduced-humidity air using the heat released by the condenser. This allows them to regulate temperature and humidity, making them widely used in applications with various temperature and humidity requirements.

[0003] However, as living standards improve, people's expectations for indoor living environments are also increasing. Multi-mode dehumidifiers, as devices for regulating air humidity, are also facing increasing demands. Traditional multi-mode dehumidifiers suffer from an irrational distribution of internal components, resulting in a non-compact internal structure and low space utilization. Furthermore, their typically rectangular exterior design, centrifugal impellers, and top-mounted air outlets prevent alternative airflow options, limiting the overall design of multi-mode dehumidifiers.

The top side of the electrical box 11 is provided with a heat dissipation outlet 114 which is connected to the volute inner cavity of the fan assembly 7 and is used to extract the gas inside the electrical box 11 with negative pressure to form a heat dissipation airflow. The corresponding electrical box 11 has a heat dissipation air inlet 115 which is connected to the inner cavity of the shell 1 and the second air inlet 3. Under the negative pressure extraction action of the fan assembly 7, the external air enters the lower inner cavity of the shell 1 from the second air inlet 3, passes through the compressor 12 and the heat dissipation air inlet 115, and cools the electronic components in the electrical box 11 before bulging out from the heat dissipation outlet 114 to form a second airflow channel; the volute side wall near the first air outlet 9 on the fan assembly 7 is also provided with a control volute wall opening and closing, which removes The moist air flow is guided out from the volute guide mechanism 13a at the side wall of the shell 1.

[0026] During operation, when the first air guide mechanism 4 opens the first air inlet 2, the second air guide mechanism 10 opens the first air outlet 9, and the volute wall guide mechanism 13a closes the second air outlet 14, the external air enters from the first air inlet 2 and the second air inlet 3, passes through the first air flow channel and the second air flow channel respectively, and is discharged from the first air outlet 9.

[0027] When the first air guide mechanism 4 closes the first air inlet 2, the second air guide mechanism 10 opens the first air outlet 9, and the volute wall guide mechanism 13a closes the second air outlet 14, the external air enters from the second air inlet 3, and is respectively diverted through the first air flow channel and the second air flow channel, and the dehumidified air flow is discharged from the first air outlet 9, and the evaporator 5 and the condenser 6 enter the purification and dehumidification mode.

[0028] When the humidity is high or the drying room needs to be dehumidified, the first air guide mechanism 4 opens the first air inlet 2, the second air guide mechanism 10 closes the first air outlet 9, and the volute wall guide mechanism 13a opens the second air outlet 14. After the external air enters from the first air inlet 2 and the second air inlet 3, it passes through the first air flow channel and the second air flow channel respectively, and the dehumidified air flow is directionally discharged from the second air outlet 14. The exhaust pipe connected to the second air outlet 14 introduces the directionally discharged dehumidified air flow into the desired location, such as drying inside the wardrobe, drying inside the clothes, drying inside the shoe cabinet or drying inside the shoes; at this time, the evaporator 5 and the condenser 6 enter the directional dehumidification mode.

[0029] like Figure 5 and Figure 6 As shown, the volute guide mechanism 13a includes a volute guide plate 130 and a directional air guide control motor (not shown). The directional air guide motor drives the deflection of the volute guide plate to control the opening and closing of the flow channel corresponding to the second air outlet 14. The second air outlet 14 is also connected to an exhaust pipe (not shown) that directs the directional exhaust dehumidified airflow to the desired location. The exhaust pipe directly directs the dehumidified airflow to the wardrobe, clothes, and shoes.

Both the first air guide mechanism 4 and the second air guide mechanism 10 utilize a connecting rod mechanism and a gear mechanism to drive the synchronous rotation of multiple air guide plates to control the opening and closing of the air outlet and the air inlet or outlet angles. Under relatively limited space conditions, the rotational movement of the air guide plates is achieved within the limited space, avoiding structural interference, achieving a compact structure, and effectively controlling the opening and closing of the air outlet and the air inlet and outlet angles.

[0032] The multi-mode dehumidifier control method includes the following steps: S1. Super dehumidification mode S1.0. The first air guide mechanism 4 opens the first air inlet 2, the second air guide mechanism 10 opens the first air outlet 9, and the volute wall guide mechanism 13a closes the second air outlet 14. The external air is filtered by the HEPA filter 17 at the first air inlet 2 and the second air inlet 3 and then passes through the first air flow channel and the second air flow channel respectively; S1.1. At the same time, compressor 12 performs frequency increase and adjusts to the highest allowable frequency; S1.2. After the air flow in the second air flow channel enters the lower inner cavity of the housing 1, it passes through the compressor 12 and the heat dissipation air inlet 115, cools the electronic components in the electrical box 11, and then bulges out from the heat dissipation outlet 114; S1.3. The second air guide mechanism 10 controls the air guide plate at the first air outlet 9 to be fully opened, and the dehumidified air flow is discharged from the first air outlet 9, and the evaporator 5 and the condenser 6 enter the super dehumidification mode; S2. Purification and dehumidification mode S2.0. The first air guide mechanism 4 closes the first air inlet 2, the second air guide mechanism 10 opens the first air outlet 9, and the volute guide mechanism 13a closes the second air outlet 14; S2.1. The external air is filtered by the HEPA filter 17 at the second air inlet 3 and then flows through the first air flow channel and the second air flow channel respectively; S2.2. At the same time, the compressor 12 operates at the set frequency; S2.3. The air flow in the second air flow channel passes through the compressor 12 and the heat inlet 115, and after the electronic components in the electrical box 11 are cooled by air, it bulges out from the heat outlet 114; S2.4. The second air guide mechanism 10 controls the air guide plate at the first air outlet 9 to be fully opened, and the dehumidified air flow is discharged from the first air outlet 9, and the evaporator 5 and the condenser 6 enter the purification and dehumidification mode; S3. Directional dehumidification mode S3.0. When the humidity is high or the drying room needs to be dehumidified, the first air guide mechanism 4 opens the first air inlet 2, the second air guide mechanism 10 closes the first air outlet 9, and the volute guide mechanism 13a opens the second air outlet 14; S3.1. The second air outlet 14 is connected to the exhaust pipe which is directed to discharge the dehumidified air flow into the desired position; S3.2. The external air is filtered by the HEPA filter 17 at the first air inlet 2 and the second air inlet 3 and then passes through the first air flow channel and the second air flow channel respectively; S3.3. At the same time, the compressor 12 operates at the set frequency; S3.4. The air flow in the second air flow channel passes through the compressor 12 and the heat inlet 115, and after cooling the electronic components in the electrical box 11, it bulges out from the heat outlet 114; S3.5. Directed by the second air outlet 14 to discharge dehumidified air, the exhaust pipe will be dehumidified air flow to the wardrobe, clothes inside, shoe cabinet or shoes inside the drying and dehumidification operation; S3.6. The evaporator 5 and the condenser 6 enter the directional dehumidification mode.

[0033] In this embodiment, when the dehumidifier is not in use at home, dust will enter the dehumidifier from the air outlet or air inlet, and adhere to the air duct inside the dehumidifier or on the evaporator 5 and condenser 6, which makes it difficult to clean. At the same time, it also provides more hiding places for bacteria and viruses, which will inevitably have an adverse effect on the air quality in the home when it is used next time. A first air guide mechanism 4 is provided at the first air inlet 2 to control the opening and closing of the air inlet through multiple air guide plates, and a second air guide mechanism 10 is provided at the first air outlet 9 to control the opening and closing of the air outlet through multiple air guide plates, so that the entire dehumidifier can effectively reduce the possibility of dust entering the interior of the machine when not in use. At the same time, a HEPA filter 17 is also installed at the second air inlet 3 to isolate and reduce noise from the cavity where the compressor 12 is located and to filter and clean the incoming gas. This can effectively reduce the entry of dust or other fine matter in the home into the interior of the machine.

[0034] Moreover, since the current dehumidifiers all use the compressor 12 as the driving source, there will inevitably be a certain amount of vibration noise during their operation. Although the existing technology uses sound insulation cotton and sponge to prevent the risk of noise transmission, the HEPA filter 17 installed at the second air inlet 3 in the present invention can form a partition with the compressor cavity and the air intake cavity, which can effectively reduce the transmission of vibration noise, help the variable frequency dehumidifier to achieve ultra-quiet operation at low frequency and low speed, and effectively improve the operating noise of the dehumidifier.

[0035] At the same time, since the flow rate of incoming air has a significant impact on the performance of the dehumidifier during the dehumidification process, in this embodiment, a first air inlet 2 and a second air inlet 3 with large air flow are respectively provided on the back side of the housing 1. The air guide plate of the first air inlet 2 can be closed. When the super dehumidifier is in operation, the air guide plate of the first air inlet 2 is fully opened. At this time, air will enter the dehumidifier from the air guide plate and the HEPA filter 17. At the same time, the compressor 12 performs a frequency-up operation and adjusts to the highest allowable frequency. The corresponding air guide plate of the first air outlet 9 is also fully opened, and the super dehumidifier can be realized. Of course, the first air inlet 2 is under the opening and closing control of the first air guide mechanism 4, the first air outlet 9 is under the opening and closing control of the second air guide mechanism 10, and the second air outlet 14 is under the opening and closing control of the volute wall guide mechanism 13a, so as to realize the change of the air flow channel at different positions of the whole machine. That is, by closing multiple sets of air guide plates, the switching control of the super dehumidification mode, the purification dehumidification mode and the directional dehumidification mode can be realized, effectively improving the control function of the whole machine.

[0036] In addition, in the variable frequency technology of the dehumidifier, there are components such as inductors and power modules that generate a large amount of heat, which require additional radiators for cooling; in this embodiment, the electrical box 11 and the compressor 12 are arranged side by side at the same position, and air flow channels are added above and below the electrical box 11. The lower end of the electrical box 11 is connected to the chassis, and the upper end of the electrical box 11 is connected to the water receiving tray 8 and the fan volute; specifically: a second air flow channel is connected to the inner cavity of the shell 1 on the lower side of the fan assembly 7. Under the negative pressure extraction action of the fan assembly 7, the external air enters the lower inner cavity of the shell 1 from the second air inlet 3, passes through the compressor 12 and the heat dissipation air inlet 115, and is taken in from the bottom of the chassis through the radiator on the main board and discharged from the upper end, taking away the heat. After the electronic components in the electrical box 1 are cooled by air, they are blown out from the heat dissipation outlet 114 to achieve the purpose of cooling, effectively solving the heat dissipation problem during the power period of the existing variable frequency electrical box 11.

[0037] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Any equivalent changes made based on the shape, structure and principle of the present invention should be included in the scope of protection of the present invention.
