Description

Technical Field

[0001] The invention relates to the field of dehumidification equipment, in particular to a multifunctional dehumidifier. Background Art

[0002] In the related art, dehumidifiers mainly include heating dehumidifiers and cooling dehumidifiers. The heating dehumidifier is an integrated machine with a condenser and an evaporator in the casing. The indoor air dissipates heat and cools down through the evaporator to reduce the water content, and then absorbs heat and heats up through the condenser to become dry hot air; the dry hot air is hotter than the indoor air, and it will increase the indoor temperature when it is discharged into the room. The cooling dehumidifier (such as an air conditioner) is a split machine, with the condenser placed outdoors and the evaporator placed indoors. The indoor air dissipates heat and cools down through the evaporator to reduce the water content and become dry cold air. The dry cold air is lower than the indoor air, and it will decrease the indoor temperature when it is discharged into the room; the outdoor air absorbs heat from the condenser and then dissipates it outdoors. As can be seen from the above, the heating dehumidifier can only heat up and dehumidify, but not cool down; while the cooling dehumidifier can only cool down and dehumidify, but not heat up and dehumidify. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a multifunctional dehumidifier that can have both heating and dehumidification functions and cooling and dehumidification functions.

[0004] The multifunctional dehumidifier according to the first aspect of the present invention comprises a second air duct, in which an evaporator and a second condenser are arranged in sequence along the wind direction, outside air enters the second air duct through the second air inlet, dissipates heat and cools down through the evaporator to precipitate water vapor, then absorbs heat and heats up through the second condenser, and is discharged through the second air outlet, comprising a first air duct, the first air duct and the second air duct are parallel, a first condenser is arranged in the first air duct, the first condenser is connected to the second condenser, the refrigerant flows into the first condenser for the first heat release and then flows into the second condenser for the second heat release, outside air enters the first air duct through the first air inlet, passes through the first condenser and carries the heat released by the first condenser and is discharged through the first air outlet.

[0005] The multifunctional dehumidifier according to the embodiment of the present invention has at least the following beneficial effects: when dehumidification without heating is required, the user installs the multifunctional dehumidifier in two separated processing areas, and places the second air duct outlet to exhaust air toward the room; then places the first air duct outlet to exhaust air toward the outside, and the heat released by the first condenser for primary heat release will be discharged to the outside without affecting the room temperature. Because the second condenser only performs secondary heat release, the heat released is less than or equal to the heat absorbed by the evaporator, which makes the heat received by the wind in the second condenser less than or equal to the heat lost in the evaporator, so the outlet air temperature is not greater than the inlet air temperature, and the exhaust air into the room will not significantly change the original temperature of the room, thus achieving dehumidification without heating.

[0006] When heating and dehumidification are required, the user places the multifunctional dehumidifier as a whole indoors, and places the second air duct outlet and the first air duct outlet to exhaust air towards the indoor room. Before leaving the second air duct outlet, the air outlet from the second air duct first passes through the evaporator to dissipate heat and cool down, and then passes through the second condenser to absorb heat and heat up. Before leaving the first air duct inlet, the air outlet from the first air duct only passes through the first condenser to absorb heat and heat up. Because the total heat supplied by the second condenser and the first condenser to the second air duct outlet and the first air duct outlet respectively is greater than the heat absorbed by the evaporator from the second air duct outlet, the air outlet from the second air duct and the first air duct outlet are discharged into the room together, which will cause the indoor temperature to rise.

[0007] According to some embodiments of the present invention, the second air duct inlet and the second air duct outlet are both facing the dehumidifier, and the wind flow direction in the second air duct is: entering from the second air duct inlet in the reverse direction, first turning to the horizontal direction and then turning to be blown out from the second air duct outlet in the forward direction. Dust in the air outside the machine falls due to its own weight and is not easy to float into the dehumidifier through the second air duct outlet and the second air duct inlet.

[0008] According to some embodiments of the present invention, the evaporator and the second condenser are arranged in a dehumidifier body, and the multifunctional dehumidifier includes: an air inlet turning pipe, a starting end of which serves as an air inlet of the second air duct, turns from the back to the side, and the end is connected to the dehumidifier body at the first side wall of the dehumidifier body; an air outlet turning pipe, a starting end of which is connected to the dehumidifier body at the second side wall of the dehumidifier body, turns from the side to the front, and the end of which serves as an air outlet of the second air duct.

[0009] According to some embodiments of the present invention, the air inlet turning pipe is installed on the first side wall of the dehumidifier body, and the air outlet turning pipe is installed on the second side wall of the dehumidifier body.

[0010] According to some embodiments of the present invention, it includes a first heat exchange box, which is installed on the back wall of the dehumidifier body, the first air duct is opened in the first heat exchange box, the first air duct outlet is opened on the back wall of the first heat exchange box, and the first air duct inlet is opened on the side wall of the first heat exchange box.

[0011] According to some embodiments of the present invention, there are multiple air inlets of the first air duct, which are respectively opened on multiple side walls of the first heat exchange box.

[0012] According to some embodiments of the present invention, fans are installed in both the second air duct and the first air duct, and the two fans drive the external air to enter the first air duct and the second air duct respectively for heat dissipation.

[0013] According to some embodiments of the present invention, a compressor and an expansion valve are included, wherein the compressor is connected to the first condenser, and the first condenser is connected to the second condenser; the second condenser is connected to the expansion valve, and the expansion valve is connected to the evaporator, and the evaporator is connected to the compressor.

[0014] According to some embodiments of the present invention, an auxiliary evaporator is provided on the evaporator, and the two are connected to each other.

[0015] According to some embodiments of the present invention, a partition plate is provided between the second air duct and the first air duct.

[0016] The multifunctional dehumidifier according to the embodiment of the present invention has at least the following beneficial effects: the partition plate separates the first air duct and the second air duct to separate the air in the two air ducts so as to avoid heat exchange between the two air ducts as much as possible.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0025] like Figure 3 and Figure 4 As shown, the multifunctional dehumidifier according to the first embodiment of the present invention comprises a second air duct 18, in which an evaporator 13 and a second condenser 12 are arranged in sequence along the wind direction, and the outside air enters the second air duct 18 through the second air duct inlet 2, dissipates heat and cools down through the evaporator 13 to precipitate water vapor, and then absorbs heat and heats up through the second condenser 12, and is discharged through the second air duct outlet 1, comprising a first air duct 17, the first air duct 17 and the second air duct 18 are arranged in parallel, a first condenser 8 is arranged in the first air duct 17, and the first condenser 8 is connected to the second condenser 12, the refrigerant flows into the first condenser 8 for the first heat release, and then flows into the second condenser 12 for the second heat release, the outside air enters the first air duct 17 through the first air duct inlet 16, passes through the first condenser 8 and carries the heat released by the first condenser 8 and is discharged through the first air duct outlet 15.

[0026] Specifically, when dehumidification without heating is required, the user installs the multifunctional dehumidifier in two separated treatment areas, and places the second air duct outlet 1 to exhaust air toward the room; then places the first air duct outlet 15 to exhaust air toward the outside, and the heat released by the first condenser 8 for primary heat release will be discharged to the outside without affecting the room temperature. Because the second condenser 12 only performs secondary heat release, the heat released is less than or equal to the heat absorbed by the evaporator 13, which makes the heat received by the wind in the second condenser 12 less than or equal to the heat lost in the evaporator 13, so the outlet air temperature is not greater than the inlet air temperature, and the exhaust air into the room will not significantly change the original temperature of the room, thus achieving dehumidification without heating. When heating and dehumidification are required, the user places the multifunctional dehumidifier as a whole indoors, and places the second air duct outlet 1 and the first air duct outlet 15 to exhaust air towards the indoor room. The air discharged from the second air duct 18 first passes through the evaporator 13 to dissipate heat and cool down before leaving the second air duct outlet 1, and then passes through the second condenser 12 to absorb heat and heat up. The air discharged from the first air duct 17 only passes through the first condenser 8 to absorb heat and heat up before leaving the first air duct air inlet 16. Because the total heat supplied by the second condenser 12 and the first condenser 8 to the air outlet of the second air duct 18 and the air outlet of the first air duct 17 respectively is greater than the heat absorbed by the evaporator 13 from the air outlet of the second air duct 18, the air outlet of the second air duct 18 and the air outlet of the first air duct 17 are discharged into the room together, which will cause the indoor temperature to rise.

[0027] In some specific embodiments of the present invention, the second air duct inlet 2 and the second air duct outlet 1 are both facing the dehumidifier, and the airflow direction in the second air duct 18 is: entering from the second air duct inlet 2 in the reverse direction, first turning horizontally and then turning to be blown out from the second air duct outlet 1 in the forward direction.

[0028] Specifically, dust in the air outside the dehumidifier falls due to its own weight and is not easily blown into the dehumidifier through the second air duct outlet 1 and the second air duct inlet 2 .

[0029] In some embodiments of the present invention, the evaporator 13 and the second condenser 12 are arranged in the dehumidifier body 3, and the multifunctional dehumidifier includes: an air inlet turning pipe 23, whose starting end pipe opening serves as the second air duct air inlet 2, turns from the back to the side, and the end is connected to the dehumidifier body 3 at the first side wall 5 of the dehumidifier body; an air outlet turning pipe 24, whose starting end is connected to the dehumidifier body 3 at the second side wall of the dehumidifier body 3, turns from the side to the front, and the end pipe opening serves as the second air duct air outlet 1.

[0030] In some embodiments of the present invention, the air inlet turning pipe 23 is installed on the first side wall 5 of the dehumidifier body, and the air outlet turning pipe 24 is installed on the second side wall of the dehumidifier body 3.

[0032] In some embodiments of the present invention, there are multiple first air duct air inlets 16 , which are respectively opened on multiple side walls of the first heat exchange box 20 .

[0033] In some embodiments of the present invention, fans are installed in both the second air duct 18 and the first air duct 17 .

[0034] Specifically, two fans drive the external air to enter the first air duct 17 and the second air duct 18 respectively for heat dissipation.

[0035] In some embodiments of the present invention, a compressor and an expansion valve are included, the compressor is connected to the first condenser 8, the first condenser 8 is connected to the second condenser 12; the second condenser 12 is connected to the expansion valve, the expansion valve is connected to the evaporator 13, and the evaporator 13 is connected to the compressor.

[0036] In some embodiments of the present invention, an auxiliary evaporator 13 is provided on the evaporator 13, and the two are connected to each other.

[0037] In some embodiments of the present invention, a partition plate is provided between the second air duct 18 and the first air duct 17 .

[0038] Specifically, the partition plate separates the air in the first air duct 17 and the second air duct 18 to avoid heat exchange between the two air ducts as much as possible.

[0039] Reference below Figure 1~Figure 5 The multifunctional dehumidifier according to the embodiment of the present invention is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0040] like Figure 4 As shown, the multifunctional dehumidifier of the present invention comprises a dehumidifier body 3, a second air duct 18 is provided in the dehumidifier body 3, and an air inlet turning pipe 23, a second heat exchange box 14, a second fan 7 and an air outlet turning pipe 24 are sequentially arranged in the second air duct 18 according to the direction of the air flow 21 in the second air duct. The air inlet turning pipe 23 is installed on the first side wall 5 of the dehumidifier body (see Figure 1 ), the beginning of the pipe opening is used as the second air duct inlet 2, turning from the back to the horizontal direction, and the end passes through the first side wall 5 of the dehumidifier body to connect to the dehumidifier body 3 and then passes through the first side wall 10 of the second heat exchange box (see Figure 3 ) is connected to the second heat exchange box 14. The second heat exchange box 14 is provided with an evaporator 13 and a second condenser 12 in sequence according to the direction of the wind flow 21 in the second air duct (see Figure 3 ). The left side wall of the second heat exchange box 14 is provided with an opening, and the second fan 7 is installed on the opening. The left wall of the dehumidifier body is provided with an outlet turning pipe 24, the starting end of which passes through the left wall (second side wall) of the dehumidifier body from the inside of the dehumidifier body 3, turns from the horizontal direction to the positive direction, and the terminal end of the pipe serves as the second air duct outlet 1. The wind flow 21 in the second air duct enters the second air duct 18 from the second air duct air inlet 2, enters the second heat exchange box 14 through the air inlet turning pipe 23, reaches the evaporator 13 for heat dissipation and cooling to precipitate water vapor, and then reaches the second condenser 12 for isohybrid heat absorption and temperature rise, and then is discharged through the outlet turning pipe 24.

[0041] like Figure 4 As shown, a first heat exchange box 20 is mounted on the back wall of the dehumidifier body 3, a first air duct 17 is provided in the first heat exchange box 20, a first air duct outlet 15 is provided on the back wall of the first heat exchange box 20, and a first fan 4 is provided on the first air duct outlet 15; there are a plurality of first air duct inlets 16, which are respectively provided on the three side walls of the first heat exchange box 20 (see FIG. Figure 1 and Figure 2 The back wall 19 of the dehumidifier body serves as a partition plate to separate the second air duct 18 from the first air duct 17. The first condenser 8 is installed in the first air duct 17 of the first heat exchange box 20, and the first condenser 8 is connected to the second condenser 12.

[0042] like Figure 5 As shown, a compressor and an expansion valve are also provided in the main body of the dehumidifier. The refrigerant flows from the compressor to the first condenser, the second condenser, the filter, the expansion valve and the first auxiliary evaporator in sequence, and then flows to the evaporator and the second auxiliary evaporator respectively. The refrigerant in the evaporator flows to the compressor and the second auxiliary evaporator respectively, and the refrigerant in the second auxiliary evaporator flows to the second condenser. The first condenser releases heat for the first time in the first air duct, and the second condenser releases heat for the second time in the second air duct. The heat exchange area and volume of the second condenser 12 are designed by the condensation temperature at the outlet of the first condenser 8 and the temperature and air volume of the fluid after the evaporator 13 in the first air duct 17, so that the cold amount of the fluid after flowing through the evaporator 13 can be partially neutralized to achieve the function of regulating the cold amount. At the same time, a good supercooling effect is also achieved on the condensation end, which greatly improves the dehumidification capacity and efficiency of the unit.

[0043] If dehumidification without heating is required, the user installs the multifunctional dehumidifier in two separated processing areas, and places the second air duct outlet 1 to exhaust air toward the indoor room, places the first heat exchange box 20 toward the outdoors, and places the first air duct outlet 15 toward the outdoors. The outdoor air is driven by the first fan 4 to enter the first air duct 17 through the first air duct inlet 16, and then passes through the first condenser 8 to perform primary cooling of the refrigerant inside (that is, the first condenser 8 performs primary heat release). The wind flow 22 in the first air duct will cause its own temperature to rise after helping the refrigerant to cool down. However, since it is discharged to the outdoors through the first air duct outlet 15, it will not cause the room temperature to rise. Since the temperature of the refrigerant in the first condenser 8 has been lowered after receiving primary cooling, the heat released after flowing into the second condenser 12 for secondary cooling (i.e., the second condenser 12 performs secondary heat release) is small; the airflow 21 in the second air duct only receives the heat released by the second condenser 12 for the secondary heat release, and the received heat is less than or equal to the heat lost at the evaporator 13. Therefore, the outlet air temperature of the second air duct 18 is not greater than the inlet air temperature, and the air discharged from the second air duct 18 into the room will not significantly change the original temperature of the room, thereby achieving dehumidification without heating.

[0044] If the room temperature needs to be raised during dehumidification, the user places the multifunctional dehumidifier as a whole indoors, and places the second air duct outlet 1 and the first air duct outlet 15 facing the indoors. This allows the heat generated by the second condenser 12 and the first condenser 8 to be discharged into the indoors along with the wind flow 21 in the second air duct and the wind flow 22 in the first air duct. The total heat of the primary heat release and the secondary heat release is greater than the heat absorbed by the evaporator 13 from the wind flow 21 in the second air duct. Therefore, this placement can increase the indoor temperature.

[0045] The multifunctional dehumidifier according to the embodiment of the present invention can achieve at least the following effects by such arrangement: when dehumidification without heating is required, the user installs the multifunctional dehumidifier in two separated processing areas, and places the second air duct outlet 1 to exhaust air toward the room; then places the first air duct outlet 15 to exhaust air toward the outside, and the heat released by the first condenser for primary heat release will be discharged to the outside without affecting the room temperature. Because the second condenser 12 only performs secondary heat release, the heat released is less than the heat absorbed by the evaporator 13, which makes the heat received by the wind in the second condenser 12 less than or equal to the heat lost in the evaporator 13, so the outlet air temperature is not higher than the inlet air temperature, and the outlet air discharged into the room will not significantly change the original room temperature, thus achieving dehumidification without heating. When heating and dehumidification are required, the user places the multifunctional dehumidifier as a whole indoors, and places the second air duct outlet 1 and the first air duct outlet 15 to exhaust air towards the indoor room. The air discharged from the second air duct 18 first passes through the evaporator 13 to dissipate heat and cool down before leaving the second air duct outlet 1, and then passes through the second condenser 12 to absorb heat and heat up. The air discharged from the first air duct 17 only passes through the first condenser to absorb heat and heat up before leaving the first air duct inlet 16. Because the total heat supplied by the second condenser 12 and the first condenser to the second air duct 18 and the first air duct 17 respectively is greater than the heat absorbed by the evaporator 13 from the second air duct 18, the air discharged from the second air duct 18 and the first air duct 17 together into the indoor room will cause the indoor temperature to rise.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
