Description

Technical Field

[0001] This utility model relates to the field of dehumidification equipment technology, specifically to a multi-functional dehumidifier. Background Technology

[0002] In related technologies, dehumidifiers mainly include heating dehumidifiers and cooling dehumidifiers. Heating dehumidifiers are integrated units, with a condenser and evaporator inside the casing. Indoor air cools down by dissipating heat through the evaporator, reducing its moisture content, and then warms up by absorbing heat in the condenser, becoming dry, hot air. This dry, hot air is warmer than the indoor air, and its discharge into the room raises the room temperature. Cooling dehumidifiers (like air conditioners) are split units, with the condenser placed outdoors and the evaporator indoors. Indoor air cools down by dissipating heat through the evaporator, reducing its moisture content, becoming dry, cold air. This dry, cold air is cooler than the indoor air, and its discharge into the room lowers the room temperature. Outdoor air absorbs heat from the condenser and then dissipates outdoors. Therefore, heating dehumidifiers can only dehumidify by heating, not by cooling; while cooling dehumidifiers can only dehumidify by cooling, not by heating. Utility Model Content

[0003] In view of this, the present invention provides a multifunctional dehumidifier to solve the problem that dehumidifiers in related technologies can only dehumidify by heating or only dehumidifying by cooling.

[0004] This utility model provides a multifunctional dehumidifier, including:

[0005] The first air duct is equipped with a first condenser and has a first air duct inlet and a first air duct outlet.

[0006] The second air duct is parallel to the first air duct. An evaporator and a second condenser are arranged in sequence along the airflow direction in the second air duct. The first condenser and the second condenser are connected. The refrigerant flows into the first condenser for primary heat release and then flows into the second condenser for secondary heat release. The second air duct has a second air duct inlet and a second air duct outlet.

[0007] The multi-functional dehumidifier has two operating modes: operating mode one and operating mode two.

[0008] In operating mode one, the air outlet of the first air duct faces outwards to exhaust air, and the air outlet of the second air duct faces inwards to exhaust air.

[0009] In operating mode two, the multi-functional dehumidifier is installed indoors, with both the first air duct outlet and the second air duct outlet facing indoors to exhaust air.

[0010] Beneficial effects: In operating mode one, the first air duct outlet faces outdoors for exhaust. Outside air enters the first air duct through the first air duct inlet, carries the heat released by the first condenser, and is then discharged through the first air duct outlet. The heat released by the first condenser during primary heat release is discharged outdoors without affecting the room temperature. Outside air enters the second air duct through the second air duct inlet, cools down through the evaporator to precipitate water vapor, and then absorbs heat and heats up through the second condenser before being discharged through the second air duct outlet. Because the second condenser only performs secondary heat release, the amount of heat released is less than or equal to the amount of heat absorbed by the evaporator. This means that the heat received by the air in the second condenser is less than or equal to the heat lost in the evaporator, so the outlet air temperature is not higher than the inlet air temperature. Therefore, the exhaust air will not significantly change the original indoor temperature, achieving dehumidification without raising the temperature. In operating mode two, the user places the entire multi-functional dehumidifier indoors, aligning both the second and first air duct outlets to exhaust air into the room. Before leaving the second air duct outlet, the air exiting the second air duct first cools down by passing through the evaporator and then absorbs heat to warm up by passing through the second condenser. The air exiting the first air duct only absorbs heat to warm up by passing through the first condenser before leaving the first air duct inlet. Because the total heat supplied to the second and first air duct outlets by the second and first condensers respectively is greater than the heat absorbed by the evaporator from the second air duct outlet, the combined exhaust of the second and first air duct outlets into the room causes the room temperature to rise. Therefore, this multi-functional dehumidifier can achieve both dehumidification without raising the temperature and dehumidification with raising the temperature.

[0011] In one optional embodiment, both the second air duct inlet and the second air duct outlet face the front of the multi-functional dehumidifier. The airflow direction in the second air duct is as follows: it enters from the back of the second air duct inlet, first turns to the horizontal, and then turns to blow out from the front of the second air duct outlet.

[0012] In one optional embodiment, the multifunctional dehumidifier includes a dehumidifier body, an inlet deflector pipe, and an outlet deflector pipe. The evaporator and the second condenser are disposed inside the dehumidifier body. The starting end of the inlet deflector pipe serves as the air inlet of the second air duct. The inlet deflector pipe turns laterally from the back direction. The end of the inlet deflector pipe is connected to the interior of the dehumidifier body on the first side wall of the dehumidifier body. The starting end of the outlet deflector pipe is connected to the interior of the dehumidifier body on the second side wall of the dehumidifier body. It turns from the lateral direction to the forward direction. The ending end of the outlet deflector pipe serves as the air outlet of the second air duct.

[0013] In one alternative embodiment, the air inlet deflector is mounted on the first side wall of the dehumidifier body, and the air outlet deflector is mounted on the second side wall of the dehumidifier body.

[0014] In one optional embodiment, the multi-functional dehumidifier further includes a first heat exchange box, which is installed on the back wall of the dehumidifier body. The first air duct is opened inside the first heat exchange box, the air outlet of the first air duct is opened on the back wall of the first heat exchange box, and the air inlet of the first air duct is opened on the side wall of the first heat exchange box.

[0015] And / or, the dehumidifier body is provided with a second heat exchange box, the end of the air inlet deflector pipe passes through the first side wall of the dehumidifier body and enters the interior of the second heat exchange box, and the evaporator and the second condenser are arranged sequentially along the airflow direction inside the second heat exchange box.

[0016] In one alternative implementation, the first air duct has multiple air inlets, which are respectively opened on multiple side walls of the first heat exchange box.

[0017] In one alternative implementation, a first fan is installed in the first air duct, and a second fan is installed in the second air duct.

[0018] In one alternative embodiment, the multi-functional dehumidifier further includes a compressor and an expansion valve, the compressor being connected to the first condenser, the first condenser being connected to the second condenser; the second condenser being connected to the expansion valve, the expansion valve being connected to the evaporator, and the evaporator being connected to the compressor.

[0019] In one alternative embodiment, the evaporator is provided with an auxiliary evaporator, and the evaporator and the auxiliary evaporator are in communication with each other.

[0020] In one alternative implementation, a partition plate is provided between the second air duct and the first air duct. Attached Figure Description

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0034] According to an embodiment of this utility model, a multi-functional dehumidifier is provided, including a first air duct 17 and a second air duct 18. The first air duct 17 contains a first condenser 8 and has a first air duct inlet 16 and a first air duct outlet 15. The second air duct 18 is parallel to the first air duct 17, and within the second air duct 18, along the airflow direction, an evaporator 13 and a second condenser 12 are sequentially arranged. The first condenser 8 and the second condenser 12 are connected. Refrigerant flows into the first condenser 8 for primary heat release and then flows into the second condenser 12 for secondary heat release. The second air duct 18 has a second air duct inlet 2 and a second air duct outlet 1. The multi-functional dehumidifier has an operating mode one and an operating mode two. In operating mode one, the first air duct outlet 15 exhausts air outdoors, and the second air duct outlet 1 exhausts air indoors. In operating mode two, the multi-functional dehumidifier is located indoors, and both the first air duct outlet 15 and the second air duct outlet 1 exhaust air indoors.

[0035] In this embodiment, during operation mode one, the first air outlet 15 faces outwards to exhaust air. Outside air enters the first air duct 17 through the first air inlet 16, carries the heat released by the first condenser 8, and is then discharged through the first air outlet 15. The heat released by the first condenser 8 during primary heat release is discharged outdoors without affecting the room temperature. Outside air enters the second air duct 18 through the second air inlet 2, cools down through the evaporator 13 to precipitate water vapor, then absorbs heat and heats up through the second condenser 12 before being discharged through the second air outlet 1. Because the second condenser 12 only performs secondary heat release, the amount of heat released is less than or equal to the amount of heat absorbed by the evaporator 13. This means that the heat received by the air in the second condenser 12 is less than or equal to the heat lost in the evaporator 13. Therefore, the outlet air temperature is not greater than the inlet air temperature, and the exhaust air will not significantly change the original indoor temperature, achieving dehumidification without raising the temperature. In operating mode two, the user places the entire multi-functional dehumidifier indoors, aligning both the second air duct outlet 1 and the first air duct outlet 15 to exhaust air into the room. Before leaving the second air duct outlet 18, the air exiting the second air duct first passes through the evaporator 13 to dissipate heat and cool down, then passes through the second condenser 12 to absorb heat and warm up. The air exiting the first air duct 17 only passes through the first condenser 8 to absorb heat and warm up before leaving the first air duct inlet 16. Because the total heat supplied by the second condenser 12 and the first condenser 8 to the second air duct outlet 18 and the first air duct outlet 17 respectively is greater than the heat absorbed by the evaporator 13 from the second air duct outlet 18, the combined exhaust of the air from the second air duct outlet 18 and the first air duct outlet 17 into the room causes the room temperature to rise. Therefore, this multi-functional dehumidifier can achieve both dehumidification without raising the temperature and dehumidification with raising the temperature.

[0036] Specifically, when dehumidification without heating is required, the user installs the multi-functional dehumidifier in two separate processing areas. The second air duct inlet 2 faces indoors, and indoor air enters the second air duct 18 through the second air duct inlet 2. The second air duct outlet 1 is positioned to exhaust air into the room. The first air duct inlet 16 faces outdoors, and the first air duct outlet 15 exhausts air outdoors. When dehumidification with heating is required, the user places the entire multi-functional dehumidifier indoors, with the first air duct inlet 16, the first air duct outlet 15, the second air duct inlet 2, and the second air duct outlet 1 all facing indoors.

[0037] In some specific embodiments of this utility model, the second air duct inlet 2 and the second air duct outlet 1 both face the front of the multi-functional dehumidifier. The airflow 21 in the second air duct is directed as follows: it enters from the back of the second air duct inlet 2, turns laterally, and then turns to blow out from the front of the second air duct outlet 1.

[0038] Specifically, dust in the outside air falls due to its own weight and is less likely to drift into the multi-functional dehumidifier through the second air outlet 1 and the second air inlet 2.

[0039] In some embodiments of this utility model, the multifunctional dehumidifier includes a dehumidifier body 3, an inlet deflector pipe 23, and an outlet deflector pipe 24. The evaporator 13 and the second condenser 12 are disposed inside the dehumidifier body 3. The beginning of the inlet deflector pipe 23 serves as the second air duct inlet 2, which turns laterally from the back and the end is connected to the dehumidifier body 3 inside the first side wall 5 of the dehumidifier body. The beginning of the outlet deflector pipe 24 is connected to the dehumidifier body 3 inside the second side wall 6 of the dehumidifier body, which turns laterally to the front and the end of the outlet deflector pipe 24 serves as the second air duct outlet 1.

[0040] Specifically, by setting up the inlet deflector 23 and the outlet deflector 24, the outside air can flow along a predetermined path, allowing the airflow to fully exchange heat with the evaporator 13 and the second condenser 12. Furthermore, it ensures that both the second air duct inlet 2 and the second air duct outlet 1 face the front of the multi-functional dehumidifier, thus enabling the second air duct 18 and its internal components to function as an indoor unit.

[0041] Specifically, the first sidewall 5 of the dehumidifier body is adjacent to the second sidewall 6 of the dehumidifier body. In one embodiment (not shown in the figure), the first sidewall 5 of the dehumidifier body is opposite to the second sidewall 6 of the dehumidifier body.

[0042] In some embodiments of this utility model, the air inlet deflector 23 is mounted on the first side wall 5 of the dehumidifier body, and the air outlet deflector 24 is mounted on the second side wall 6 of the dehumidifier body.

[0043] In some embodiments of this utility model, the multifunctional dehumidifier further includes a first heat exchange box 20, which is mounted on the back wall 19 of the dehumidifier body. A first air duct 17 is opened inside the first heat exchange box 20, an air outlet 15 of the first air duct is opened on the back wall of the first heat exchange box 20, and an air inlet 16 of the first air duct is opened on the side wall of the first heat exchange box 20; and / or, a second heat exchange box 14 is provided inside the dehumidifier body 3, and the end of the air inlet deflector 23 passes through the first side wall 5 of the dehumidifier body and enters the interior of the second heat exchange box 14. An evaporator 13 and a second condenser 12 are arranged sequentially along the airflow direction inside the second heat exchange box 14.

[0044] Specifically, since the first heat exchange box 20 is installed on the back wall 19 of the dehumidifier body, the first air duct 17 is opened inside the first heat exchange box 20, the first air duct outlet 15 is opened on the back wall of the first heat exchange box 20, and the first air duct inlet 16 is opened on the side wall of the first heat exchange box 20, it is convenient for the first heat exchange box 20 to be used as an outdoor unit and the dehumidifier body 3 to be used as an indoor unit when dehumidification is not heated.

[0045] In some embodiments of this utility model, there are multiple first air duct inlets 16, which are respectively opened on multiple side walls of the first heat exchange box 20.

[0046] In some embodiments of this utility model, a first fan 4 is installed in the first air duct 17, and a second fan 7 is installed in the second air duct 18.

[0047] Specifically, the first fan 4 drives outside air into the first air duct 17 for heat exchange, and the second fan 7 drives outside air into the second air duct 18 for heat exchange.

[0048] In some embodiments of this utility model, the multi-functional dehumidifier further includes a compressor and an expansion valve. The compressor is connected to a first condenser 8, and the first condenser 8 is connected to a second condenser 12. The second condenser 12 is connected to an expansion valve, the expansion valve is connected to an evaporator 13, and the evaporator 13 is connected to the compressor.

[0049] In some embodiments of this utility model, an auxiliary evaporator is provided on the evaporator 13, and the evaporator 13 and the auxiliary evaporator are interconnected.

[0050] Specifically, one or more auxiliary evaporators can be provided. For example, there are two auxiliary evaporators, namely a first auxiliary evaporator and a second auxiliary evaporator. The first auxiliary evaporator and the second auxiliary evaporator are respectively connected to the evaporator 13, and the first auxiliary evaporator and the second auxiliary evaporator can be connected to each other.

[0051] In some embodiments of this utility model, a partition plate is provided between the second air duct 18 and the first air duct 17.

[0052] Specifically, the partition separates the air in the first air duct 17 and the second air duct 18 to minimize heat exchange between them.

[0053] The following is for reference. Figures 1-5 A multifunctional dehumidifier according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0054] like Figure 4 As shown, this utility model of a multi-functional dehumidifier includes a dehumidifier body 3. A second air duct 18 is provided inside the dehumidifier body 3. Following the airflow direction 21 within the second air duct 18, an inlet deflector pipe 23, a second heat exchange box 14, a second fan 7, and an outlet deflector pipe 24 are sequentially arranged within the second air duct 18. The inlet deflector pipe 23 is installed on the first side wall 5 of the dehumidifier body (see...). Figure 1 Its initial pipe opening serves as the second air duct inlet 2, turning laterally from the back, and its end passes through the first side wall 5 of the dehumidifier body and enters the dehumidifier body 3, then passes through the first side wall 10 of the second heat exchange box (see...). Figure 3 The evaporator 13 and the second condenser 12 are connected to the second heat exchange box 14. Inside the second heat exchange box 14, an evaporator 13 and a second condenser 12 are arranged sequentially according to the airflow direction 21 in the second air duct (see...). Figure 3An opening is made on the left side wall of the second heat exchange box 14, and the second fan 7 is mounted on this opening. An air outlet deflector duct 24 is installed on the left wall of the dehumidifier body 3. Its starting end passes through the left wall (second side wall) of the dehumidifier body 3 from inside the dehumidifier body 3, turning from a horizontal direction to a positive direction. Its end opening serves as the air outlet 1 of the second air duct. The airflow 21 in the second air duct enters the second air duct 18 from the second air duct inlet 2, enters the second heat exchange box 14 through the air inlet deflector duct 23, reaches the evaporator 13 for heat dissipation and cooling to precipitate water vapor, then reaches the second condenser 12 for equal humidity heat absorption and temperature rise, and is then discharged through the air outlet deflector duct 24.

[0055] like Figure 4 As shown, a first heat exchange box 20 is mounted on the back wall 19 of the dehumidifier body. A first air duct 17 is opened inside the first heat exchange box 20. The air outlet 15 of the first air duct is opened on the back wall of the first heat exchange box 20, and a first fan 4 is mounted on the air outlet 15. There are multiple air inlets 16 of the first air duct, which are respectively opened on the three side walls of the first heat exchange box 20 (see...). Figure 1 and Figure 2 The back wall 19 of the dehumidifier body acts as a partition to separate the second air duct 18 and the first air duct 17. The first air duct 17 of the first heat exchange box 20 contains the first condenser 8, which is connected to the second condenser 12.

[0056] like Figure 5 As shown, the dehumidifier body 3 also includes a compressor and an expansion valve. Refrigerant flows sequentially from the compressor to the first condenser 8, the second condenser 12, the filter, the expansion valve, and the first auxiliary evaporator, then to the evaporator 13 and the second auxiliary evaporator. Refrigerant in the evaporator 13 flows to the compressor and the second auxiliary evaporator, while refrigerant in the second auxiliary evaporator flows to the second condenser 12. The first condenser 8 releases heat initially in the first air duct 17, and the second condenser 12 releases heat a second time in the second air duct 18. The heat exchange area and volume of the second condenser 12 are designed based on the condensation temperature at the outlet of the first condenser 8 and the temperature and flow rate of the fluid after the evaporator 13 in the first air duct 17. This allows for partial neutralization of the cold air flowing through the evaporator 13, achieving the effect of regulating the cold air volume. Simultaneously, it also provides excellent subcooling at the condenser end, significantly improving the unit's dehumidification capacity and efficiency.

[0057] If dehumidification without heating is required, the user should install the multi-functional dehumidifier in a separate processing area, with the second air duct outlet 1 facing indoor exhaust, the first heat exchange box 20 facing outdoors, and the first air duct outlet 15 facing outdoors. 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 undergoes primary cooling of the refrigerant inside the first condenser 8 (i.e., the first condenser 8 performs primary heat release). The airflow 22 in the first air duct helps to cool the refrigerant, which causes it to heat up. However, since it is exhausted outdoors through the first air duct outlet 15, it will not cause the room temperature to rise. Since the refrigerant in the first condenser 8 has already cooled down after primary cooling, it flows into the second condenser 12 to undergo secondary cooling (i.e., the second condenser 12 performs secondary heat release), releasing a small amount of heat. The airflow 21 in the second air duct only receives the heat released by the second condenser 12 during 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. As a result, the air outlet air from the second air duct 18 will not significantly change the original indoor temperature when it is discharged into the room, thus achieving dehumidification without raising the temperature.

[0058] If a higher room temperature is needed during dehumidification, the user places the entire multi-functional dehumidifier indoors, with the second air outlet 1 and the first air outlet 15 facing inwards. This ensures that the heat generated by the second condenser 12 and the first condenser 8 is exhausted into the room along with the airflow 21 and 22 in the second and first air ducts. The total heat generated by the primary and secondary heat releases is greater than the heat absorbed by the evaporator 13 from the airflow 21 in the second air duct. Therefore, this arrangement can raise the room temperature.

[0059] According to the embodiments of this utility model, the multi-functional dehumidifier, through the following configuration, can achieve at least the following effects: When dehumidification without heating is required, the user installs the multi-functional dehumidifier in a separate processing area, aligning the second air duct outlet 1 towards the indoor exhaust; then, the first air duct outlet 15 is aligned towards the outdoor exhaust. The heat released by the first condenser 8 during primary heat release is discharged outdoors without affecting the room temperature. Because the second condenser 12 only performs secondary heat release, the amount of heat released is less than the amount of heat absorbed by the evaporator 13. This results in the heat received by the air in the second condenser 12 being less than or equal to the heat lost in the evaporator 13. Therefore, the outlet air temperature is not higher than the inlet air temperature, and the exhaust air will not significantly change the original indoor temperature, achieving dehumidification without heating. When heating and dehumidification are required, the user places the entire multi-functional dehumidifier indoors, with both the second air duct outlet 1 and the first air duct outlet 15 facing the room for exhaust. Before leaving the second air duct outlet 1, the air from the second air duct 18 first passes through the evaporator 13 to dissipate heat and cool down, and then passes through the second condenser 12 to absorb heat and heat up. Before leaving the first air duct inlet 16, the air from the first air duct 17 only passes through the first condenser 8 to absorb heat and heat up. Because the total heat supplied by the second condenser 12 and the first condenser 8 to the second air duct outlet 18 and the first air duct outlet 17 is greater than the heat absorbed by the evaporator 13 from the second air duct outlet 18, the air from the second air duct outlet 18 and the first air duct outlet 17 together being discharged into the room will cause the room temperature to rise.
