Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifiers, and particularly to a dehumidifier. Background Art

[0002] The structure of a dehumidifier includes a refrigeration system, a cabinet system, a fan system, and an electric control system. Among them, the refrigeration system operates as follows: The refrigerant enters the compressor and is compressed into a high-temperature and high-pressure refrigerant vapor. Then, it condenses and releases heat in the condenser to become a high-temperature and high-pressure refrigerant liquid. After undergoing an adiabatic throttling process through a throttling component, it becomes a low-temperature and low-pressure refrigerant liquid (or two-phase state), and finally enters the evaporator to evaporate and absorb heat to become a low-temperature and low-pressure refrigerant vapor and then flows back to the compressor, repeating this cycle.

[0003] Based on the above refrigeration system, the air dehumidification process of the dehumidifier is as follows: The fan draws indoor air into the upper housing of the dehumidifier through the air inlet and passes through the evaporator. At this time, the indoor air is cooled and dehumidified in the evaporator to become low-temperature saturated wet air. Then, the low-temperature saturated wet air is heated and dehumidified by the condenser to become dry medium-temperature gas and is discharged into the indoor environment.

[0004] In the related art, the fan of the dehumidifier is generally a constant-speed motor, which is provided with high / low wind speed gears or high / mid / low wind speed gears. As a result, when the constant-speed motor is at a certain gear, the air volume flowing through the evaporator is approximately the same under different indoor thermal and humidity environments. Furthermore, the dehumidification amount cannot be effectively controlled, and the user's usage requirements cannot be better met, affecting the user's comfort. Summary of the Invention

[0035] The following details the embodiments of the present invention. The embodiments described with reference to the drawings are exemplary. The following refers to Figures 1 - 8Describe the dehumidifier 100 according to an embodiment of the present invention.

[0036] As Figures 1 - 8 shown, the dehumidifier 100 according to an embodiment of the present invention includes: a compressor, a condenser 2, a throttling device, an evaporator 1, an air volume regulating plate 7, a temperature sensor 4, a humidity sensor 5, and a controller 6.

[0037] Specifically, the refrigerant circulates in a refrigerant circuit formed in the order of the compressor, the condenser 2, the throttling device, and the evaporator 1 in the refrigeration cycle. Among them, the evaporator 1 and the condenser 2 are arranged at intervals to define an air flow channel 3 between the evaporator 1 and the condenser 2. The air volume regulating plate 7 is rotatably provided at the entrance of the air flow channel 3 for adjusting the opening degree of the entrance of the air flow channel 3. The temperature sensor 4 is used to detect the temperature of the indoor environment. The humidity sensor 5 is used to detect the humidity of the indoor environment.

[0038] For example, in Figures 1 - 5 the example, the dehumidifier 100 further includes a housing 10. The evaporator 1, the condenser 2, the temperature sensor 4, the humidity sensor 5, and the controller 6 are all arranged inside the housing 10. The housing 10 has an air inlet and an air outlet 101. The evaporator 1 is opposite to the air inlet, and the condenser 2 is located on the side of the evaporator 1 away from the air inlet. Among them, the evaporator 1 is used to absorb heat from the low-temperature and low-pressure refrigerant liquid flowing out of the throttling device into a low-temperature and low-pressure refrigerant gas, and dehumidify and cool the indoor air passing over the evaporator 1. The condenser 2 is used to cool and depressurize the high-temperature and high-pressure refrigerant gas discharged from the compressor into a medium-temperature and medium-pressure refrigerant liquid.

[0039] The controller 6 is configured to:

[0040] S1. Control the air volume regulating plate 7 to open a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5 to adjust the air volume flowing through the evaporator 1.

[0041] The controller 6 may include a storage module 62 and a processing module 61. The storage module 62 is communicatively connected to the processing module 61. The storage module 62 is used to store the opening degrees of the entrances corresponding to the air volumes flowing through the evaporator 1 under different refrigerants, different indoor environment temperatures, and different indoor environment humidities. The processing module 61 is used to obtain the data detected by the temperature sensor 4 and the humidity sensor 5 in real time, retrieve the corresponding opening degrees of the entrances from the storage module 62 according to the obtained temperature and humidity data, and adjust the entrances to the corresponding opening degrees to adjust the air volume flowing through the evaporator 1 to increase the dehumidification amount of the dehumidifier 100.

[0042] When the dehumidifier 100 dehumidifies, the controller 6 controls the air volume adjusting plate 7 to open to the opening degree corresponding to the current temperature and current humidity of the indoor environment. Since there is a cavity between the evaporator 1 and the condenser 2, part of the indoor air flowing into the housing 10 through the air inlet flows through the evaporator 1 to the condenser 2, and the other part directly flows to the condenser 2 through the opening. The condenser 2 can heat the air flowing to it to remove the moisture in the air. Thus, the ventilation volume of the evaporator 1 is reduced, and the ventilation volume in the air flow channel 3 is increased, so that the dehumidification amount of the dehumidifier 100 can be adjusted according to the actual situation (current temperature and current humidity) of the indoor environment. While improving the dehumidification amount, the comfort of the user is ensured, so that the dehumidifier 100 can better meet the usage requirements of the user.

[0043] For the dehumidifier 100 according to an embodiment of the present invention, by arranging the air volume adjusting plate 7 at the entrance of the air flow channel 3 defined by the evaporator 1 and the condenser 2, and the controller 6 is configured to adjust the opening degree of the air volume adjusting plate 7 according to the current temperature and current humidity of the indoor environment. Thus, compared with the traditional dehumidifier, the air volume flowing through the evaporator 1 can be better adjusted according to the actual situation of the indoor environment, so that more air can directly flow to the condenser 2, thereby improving the dehumidification amount of the dehumidifier 100 and better meeting the usage requirements of the user.

[0044] According to some embodiments of the present invention, the dehumidifier 100 further includes a stepping motor 9, and the stepping motor 9 is connected to the air volume adjusting plate 7. S1': When the stepping motor 9 works, the stepping motor 9 drives the air volume adjusting plate 7 to swing to adjust the opening degree of the entrance. As Figure 4 and Figure 5 shown, the stepping motor 9 can be arranged at one end in the length direction of the air volume adjusting plate 7, and the gears of the stepping motor 9 can be divided into multiple gears. The swing angle of the air volume adjusting plate 7 is controlled by different gears of the stepping motor 9 to realize the adjustment of the opening degree of the entrance. By arranging the stepping motor 9, not only can the dehumidification amount of the dehumidifier 100 be effectively improved, but also the operation energy efficiency of the dehumidifier 100 at different temperatures and humidities is improved, effectively saving electricity.

[0045] Specifically, after the processing module 61 receives the data of the current temperature and current humidity of the indoor environment, and finds out the opening angle of the air volume adjusting plate 7 corresponding to it in the storage module 62 according to the received data, then the processing module 61 determines the current value flowing to the stepping motor 9 according to the opening angle information of the air volume adjusting plate 7, and then transmits the above current value to the stepping motor 9 to control the air volume adjusting plate 7 to open the corresponding angle, so as to realize opening the entrance to the corresponding opening degree and increasing the air volume directly flowing to the condenser 2.

[0046] According to some embodiments of the present invention, as Figure 9 shown, the controller 6 is further configured to:

[0047] Before controlling the air volume adjustment plate 7 to open at a corresponding angle to adjust the air volume flowing through the evaporator 1 according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5,

[0048] S0. Determine the refrigerant air volume correction coefficient according to the refrigerant type of the dehumidifier 100. Through this step, the optimal air volume corresponding to different refrigerants during dehumidification can be effectively determined to ensure that the air volume flowing to the evaporator 1 is the optimal air volume.

[0049] Further, as Figure 9 shown, the controller 6 is further configured to:

[0050] After controlling the air volume adjustment plate 7 to open at a corresponding angle to adjust the air volume flowing through the evaporator 1 according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5,

[0051] S2. Determine whether the dehumidifier 100 enters the defrosting mode;

[0052] S3. If the dehumidifier 100 enters the defrosting mode, control the air volume adjustment plate 7 to close the inlet of the air flow channel 3;

[0053] If the dehumidifier 100 does not enter the defrosting mode, re-control the air volume adjustment plate 7 to open at a corresponding angle to adjust the air volume flowing through the evaporator 1 according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5.

[0054] Specifically, when the dehumidifier 100 is in the defrosting mode, by making the opening degree of the inlet of the air flow channel 3 be 0, it can be ensured that the air flowing into the dehumidifier 100 through the air inlet can flow through the evaporator 1 to the condenser 2, so that the air volume passing through the dehumidifier 100 is the largest in the defrosting mode, thereby ensuring the effectiveness of defrosting control and achieving the fastest defrosting. When the dehumidifier 100 is in the non-defrosting mode, the indoor can be dehumidified according to the actual situation of the indoor environment.

[0055] Even further, as Figure 9 shown, the controller 6 is further configured to:

[0056] After the dehumidifier 100 enters the defrosting mode and controls the air volume adjustment plate 7 to close the inlet of the air flow channel 3,

[0057] S4. Determine whether the dehumidifier exits the defrosting mode;

[0058] S5. If the dehumidifier 100 exits the defrosting mode, determine whether the dehumidifier 100 enters the shutdown mode;

[0059] S6. If the dehumidifier 100 enters the shutdown mode, control the air volume adjustment plate 7 to close the inlet of the air flow channel 3;

[0060] If the dehumidifier 100 does not enter the shutdown mode, the air volume adjustment plate 7 is reopened at a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5 to adjust the air volume flowing through the evaporator 1;

[0061] If the dehumidifier 100 does not exit the defrosting mode, the air volume adjustment plate 7 is reopened at a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5 to adjust the air volume flowing through the evaporator 1.

[0062] In step S6, when the dehumidifier 100 exits the defrosting mode and enters the shutdown mode, it indicates that the dehumidifier 100 has completed the dehumidification work. At this time, the air volume adjustment plate 7 is rotated to the initial position to ensure the normal progress of the next dehumidification work. When the dehumidifier 100 does not enter the shutdown mode, it indicates that the dehumidification of the dehumidifier 100 is still in progress. It is necessary to adjust the air volume flowing to the condenser 2 in real time according to the actual situation of the indoor environment, so as to increase the air volume directly flowing to the condenser 2 and reduce the air volume flowing to the evaporator 1, ensuring the dehumidification capacity and dehumidification efficiency of the dehumidifier 100.

[0063] According to some embodiments of the present invention, as Figure 9 shown, the controller 6 is further configured to:

[0064] After determining the refrigerant air volume correction coefficient according to the refrigerant type of the dehumidifier 100,

[0065] S0'. Determine whether the compressor has been continuously running for a first duration;

[0066] If the judgment result is yes, execute the step of controlling the air volume adjustment plate 7 to open at a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5;

[0067] If the judgment result is no, continue to determine whether the compressor has been continuously running for a first duration.

[0068] When the compressor runs continuously for the first duration, the working state of the surface dehumidifier 100 tends to be stable, and the dehumidifier 100 also dehumidifies the indoor environment for a certain period of time. At this time, the current temperature and current humidity of the indoor environment are detected, and the dehumidification situation of the dehumidifier 100 within the first duration can be effectively judged, and then the dehumidification operation is continued according to the actual situation of the indoor environment. When the compressor runs continuously for the first duration, it indicates that the running time of the dehumidifier 100 is short and the dehumidification effect is not obvious. Detecting the current temperature and current humidity of the indoor environment cannot accurately reflect the actual situation of the indoor environment, and the dehumidifier 100 needs to continue for a period of time.

[0069] Further, as Figure 2 shown, the dehumidifier 100 further includes a blower 12, and the blower 12 is used to suck indoor air and flow through the evaporator 1 and the condenser 2 in sequence;

[0070] As Figure 9 shown, the controller 6 is further configured to:

[0071] If the compressor runs continuously for the first duration;

[0072] S11. Judge whether the current rotation speed of the blower 12 is high wind speed;

[0073] S12. If the current rotation speed of the blower 12 is high wind speed, control the air volume regulating plate 7 to open a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5;

[0074] S13. If the current rotation speed of the blower 12 is not high wind speed, judge whether the current rotation speed of the blower 12 is medium wind speed;

[0075] S14. If the current rotation speed of the blower 12 is medium wind speed, control the air volume regulating plate 7 to open a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5;

[0076] S15. If the current rotation speed of the blower 12 is not medium wind speed, judge whether the current rotation speed of the blower 12 is low wind speed;

[0077] S16. If the current rotation speed of the blower 12 is low wind speed, control the air volume regulating plate 7 to open a corresponding angle according to the current temperature of the indoor environment detected by the temperature sensor 4 and the current humidity of the indoor environment detected by the humidity sensor 5.

[0078] For example, in combination with Figure 10, when the fan 12 of the dehumidifier 100 rotates at a high wind speed, the opening angle X1 of the air volume adjustment plate 7 can be determined according to the indoor temperature and humidity, and the stepper motor 9 can be controlled to drive the air volume adjustment plate 7 to rotate to X1 degrees; when the fan 12 of the dehumidifier 100 rotates at a medium wind speed, the opening angle X2 of the air volume adjustment plate 7 can be determined according to the indoor temperature and humidity, and the stepper motor 9 can be controlled to drive the air volume adjustment plate 7 to rotate to X2 degrees; when the fan 12 of the dehumidifier 100 rotates at a low wind speed, the opening angle X3 of the air volume adjustment plate 7 can be determined according to the indoor temperature and humidity, and the stepper motor 9 can be controlled to drive the air volume adjustment plate 7 to rotate to X3 degrees. Among them, X1, X2, and X3 may be equal or unequal. Thus, the ventilation volume of the evaporator 1 can be controlled more precisely, and the air volume flowing directly to the condenser 2 can be increased, so that the dehumidification amount of the dehumidifier 100 can be further increased, and the dehumidification efficiency of the dehumidifier 100 can be further improved.

[0079] According to some embodiments of the present invention, first windshields 8 are respectively provided between the two sides of the evaporator 1 and the condenser 2. An air flow channel 3 is jointly defined among the two first windshields 8, the evaporator 1, and the condenser 2. The air volume adjustment plate 7 is located at the top of the evaporator 1 and the condenser 2. Refer to Figures 2 - 5 , one ends of the two first windshields 8 are respectively connected to the two ends in the length direction of the air volume adjustment plate 7, and the other ends of the two first windshields 8 can be connected to the end plates of the evaporator 1 or the condenser 2 through buckles or screws to ensure the installation reliability of the two first windshields 8. When the dehumidifier 100 dehumidifies, the controller 6 can adjust the opening degree of the inlet by controlling the opening angle of the air volume adjustment plate 7.

[0080] Among them, the length of the air volume adjustment plate 7 should be greater than the distance between the two end plates of the evaporator 1 or the condenser 2, the width of the air volume adjustment plate 7 should be equal to the distance between the condenser 2 and the evaporator 1, and the thickness of the air volume adjustment plate 7 should meet the drop strength requirements of the product. The height of the first windshield 8 should be higher than the heights of the condenser 2 and the evaporator 1, the width of the first windshield 8 should be equal to the distance between the condenser 2 and the evaporator 1, and the thickness of the first windshield 8 should meet the drop strength requirements of the product. Optionally, the gap between the first windshield 8 and the evaporator 1 or the condenser 2 can be sealed with sponge or other materials to avoid air leakage and affect the accuracy of air volume control.

[0081] Of course, the present invention is not limited thereto. In some other embodiments of the present invention, a second wind baffle is provided between the tops of the evaporator 1 and the condenser 2. A common air flow passage 3 is defined among the second wind baffle, the evaporator 1 and the condenser 2. There are a plurality of air volume adjusting plates 7, and the plurality of air volume adjusting plates 7 are respectively arranged between the two sides of the evaporator 1 and the condenser 2. In the description of the present invention, "a plurality of" means two or more. When the dehumidifier 100 dehumidifies, the controller 6 can adjust the opening degree of the inlet by controlling the rotation angle of at least one of the two second wind baffles. At this time, a part of the indoor air flowing into the dehumidifier 100 through the air inlet flows from the side of the condenser 2 to the condenser 2 to ensure the air volume directly flowing to the condenser 2. Optionally, the gap between the second wind baffle and the evaporator 1 or the condenser 2 can be sealed with sponge or other materials to avoid air leakage and affect the accuracy of air volume control.

[0082] According to some embodiments of the present invention, as Figure 7 and Figure 8 shown, the dehumidifier 100 further includes an auxiliary condenser 11. The auxiliary condenser 11 is arranged in the air flow passage 3 and is used for secondary utilization of the air flowing through the evaporator 1, and performing heat exchange on the indoor shunt air entering from the inlet of the air flow passage 3 to realize dehumidification of the indoor shunt air. For example, the auxiliary condenser 11 is located in the cavity between the evaporator 1 and the condenser 2. A part of the air flowing into the housing 10 through the air inlet flows through the evaporator 1 to the auxiliary condenser 11. The auxiliary condenser 11 performs secondary utilization of the air flowing through the evaporator 1. Another part directly flows to the auxiliary condenser 11 from the inlet of the air flow passage 3 to perform heat exchange on the air in the air flow passage 3. The auxiliary condenser 11 can effectively remove a part of the moisture in the air. Finally, all the air flows out from the air outlet 101 after being heated by the condenser 2. The condenser 2 can further remove the moisture in the air, thereby improving the dehumidification capacity of the dehumidifier 100 and the dehumidification efficiency of the dehumidifier 100.

[0083] Furthermore, the auxiliary condenser 11 includes a frame and a plurality of condensate sheets. The plurality of condensate sheets are arranged in the frame. The plurality of condensate sheets are arranged at intervals along the thickness direction of the condensate sheet. A plurality of through holes 111 are formed on each condensate sheet at intervals along the length direction of the condensate sheet. An extension part extending towards one side in the thickness direction of the condensate sheet is provided at the edge of each through hole 111. The plurality of extension parts of the plurality of condensate sheets are respectively opposite along the thickness direction of the condensate sheet to respectively form a plurality of channels. The plurality of channels communicate with the inlet of the air flow passage 3. The indoor air flowing through the evaporator 1 flows through the plurality of condensate sheets to exchange heat with the indoor shunt air in the plurality of channels.

[0084] For example, when the air volume adjustment plate 7 is located at the top of the air flow channel 3, multiple condensate sheets can be arranged at intervals in the width direction of the frame. Two adjacent condensate sheets jointly define a channel. At this time, each condensate sheet is arranged horizontally, that is, the length direction of the condensate sheet is the same as the length direction of the frame, and each channel extends horizontally.
