Description

Technical Field

[0001] The invention relates to the technical field of dehumidifiers, in particular to a dehumidifier with an auxiliary condensation structure. Background Art

[0002] A dehumidifier, also known as a dehumidifier, moisture absorber, or dehumidifier, is composed of a compressor, a heat exchanger, a fan, a water tank, a casing, and a controller. Its working principle is: the fan draws humid air into the machine, passes through the heat exchanger, and the moisture in the air condenses into water droplets. The treated dry air is discharged out of the machine, and this cycle reduces the indoor humidity.

[0003] In the prior art, for example, the Chinese patent number is CN204034526U, which discloses a dehumidifier, which includes a housing, a dehumidification wheel, a heater, and a heat exchanger. The housing has an installation space, and an air inlet and an air outlet connected to the installation space. The dehumidification wheel is arranged in the installation space, and is used to absorb moisture in the air entering from the air inlet. The heater is used to heat the dehumidification wheel. The heat exchanger condenses the moisture generated by the heater heating the dehumidification wheel into water, and the heat exchanger includes a polygonal first tube body, and a plurality of second tube bodies, and the channel cross-sectional area of ​​each second tube body is smaller than the channel cross-sectional area of ​​the first tube body. By providing the first tube body to cooperate with the second tube body, a larger heat exchange area can be provided, thereby improving the heat exchange efficiency.

[0004] However, in the prior art, in addition to increasing the power of the compressor to improve the energy efficiency of the dehumidifier, the energy efficiency of the dehumidifier can only be improved by increasing the area of ​​the heat exchanger as mentioned above. However, both of these methods will increase the energy consumption of the dehumidifier itself, and the use of a high-power compressor or a large-area heat exchanger will also cause the overall size of the dehumidifier to be too large and increase the production cost of the dehumidifier. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art. A dehumidifier with an auxiliary condensation structure is proposed, so that the dehumidifier can produce more water after being equipped with the condensation structure, so that the dehumidifier can improve its own dehumidification efficiency without increasing the compressor power or increasing the heat exchange area, thereby reducing the energy consumption of the dehumidifier and effectively avoiding the problem of the dehumidifier being too large in overall size and high production cost due to adjusting the compressor or heat exchanger.

[0006] To achieve the above object, the present invention provides the following technical solution: a dehumidifier with an auxiliary condensation structure, comprising:

[0007] A shell, wherein an air inlet and an air outlet are formed on the shell, and an air duct connecting the air inlet and the air outlet is formed inside the shell;

[0008] an evaporator, disposed at the air inlet;

[0009] A condensation component is arranged on a side of the evaporator away from the air inlet and in contact with the evaporator. The condensation component includes a plurality of condensation tubes connected in parallel, each condensation tube includes a hollow heat-conducting tube and a No. 1 connector and a No. 2 connector arranged at both ends of the hollow heat-conducting tube; an air flow port is provided on the No. 1 connector and the No. 2 connector, and the air flow port is communicated with the inner cavity of the hollow heat-conducting tube. The air flow ports of the No. 1 connector and the No. 2 connector are opened in opposite directions, and the gas flow direction of the air flow port is perpendicular to the gas flow direction in the hollow heat-conducting tube. After the air enters the dehumidifier, part of the air enters the evaporator for dehumidification, and part of the air enters the condensation component. The air entering the condensation component contacts the cold air generated by the evaporator and undergoes heat exchange condensation, so that the moisture in the air is fully condensed at the condensation component;

[0010] A radiator is arranged on a side of the condensing assembly away from the evaporator and forms a gap with the condensing assembly; and a compressor is connected to the evaporator.

[0011] Preferably, both the No. 1 connector and the No. 2 connector are provided with connecting sleeves for connecting the hollow heat pipe.

[0012] Preferably, one side of the second connector is connected to a mounting rod, and the other side is provided with a mounting groove matching the mounting rod.

[0013] Preferably, a partition middle plate is provided between the upper and lower ends of the air flow port.

[0014] Preferably, it also includes a control panel, which is arranged on the top of the shell and is used to input control signals.

[0015] Preferably, it also includes an electric control component, which is arranged in a shell below the control panel and electrically connected to the control panel for receiving control signals from the control panel and controlling the operation of the dehumidifier.

[0017] Preferably, it also includes a water tank, which is arranged directly below the fan and is used to collect liquid condensed from the evaporator and the condensation assembly.

[0018] Preferably, a cavity for accommodating a water tank is provided inside the shell.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, through the contact arrangement between the condensation component and the evaporator, after the air enters the dehumidifier, part of the air enters the evaporator for dehumidification, and part of the air enters the condensation component. The air entering the condensation component contacts the cold air generated by the evaporator and undergoes heat exchange condensation, so that the moisture in the air is fully condensed at the condensation component, thereby enabling the dehumidifier to produce more water through the condensation component on the basis of the dehumidification of the original evaporator, so that the dehumidifier installed with the condensation component can increase the dehumidification capacity from 13.5L / day to 15.5L / day, and the energy efficiency from 2.25L / kw.h to 2.583L / kw.h, which significantly improves the energy efficiency of the dehumidifier and reduces the energy consumption of the dehumidifier; and the dehumidifier does not need to use a high-power compressor or increase the area of ​​the heat exchanger to improve its own dehumidification energy efficiency, effectively avoiding the problem of the dehumidifier being too large in overall size and high in production cost due to adjustment of the compressor or the heat exchanger.

[0021] 2. In the present invention, by adopting a condensing component with a special structure, the air can be decelerated when entering the condensing tube, and the flow time of the flowing air in the hollow heat-conducting tube is prolonged, ensuring that the air can fully contact with the cold air generated by the evaporator and perform heat exchange and cooling, thereby achieving sufficient cooling of the air and condensation of water vapor; and the condensing component with a special structure can be adaptively adjusted in size according to the size of the evaporator of the dehumidifier, thereby improving the applicability of the condensing component.

[0022] 3. In the present invention, the radiator and the condensing assembly are spaced apart so that the radiator will not affect the condensing effect of the condensing assembly when working, thereby ensuring the stable operation of the condensing assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1-4 Shown: A dehumidifier with an auxiliary condensation structure, comprising:

[0040] A housing 1, wherein an air inlet 11 and an air outlet 13 are formed on the housing 1, and an air duct connecting the air inlet 11 and the air outlet 13 is formed inside the housing 1;

[0041] an evaporator 3, arranged at the air inlet 11;

[0042] The condensation component 5 is arranged on a side of the evaporator 3 away from the air inlet 11 and in contact with the evaporator 3;

[0043] The radiator 6 is arranged on a side of the condensing component 5 away from the evaporator 3 and forms a gap with the condensing component 5;

[0044] A compressor is connected to the evaporator 3 .

[0045] In this embodiment, the condensation assembly 5 includes a plurality of condensation tubes connected in parallel, each of which includes a hollow heat-conducting tube 51 and a No. 1 connector 52 and a No. 2 connector 54 arranged at both ends of the hollow heat-conducting tube 51; the No. 1 connector 52 and the No. 2 connector 54 are both provided with air flow ports 56, the air flow ports 56 are communicated with the inner cavity of the hollow heat-conducting tube 51, the air flow ports 56 of the No. 1 connector 52 and the No. 2 connector 54 are opened in opposite directions, and the gas flow direction of the air flow ports 56 is perpendicular to the gas flow direction in the hollow heat-conducting tube 51. After the air enters the dehumidifier, part of the air enters the evaporator 3 for dehumidification, and part of the air enters the condensation assembly 5. The air entering the condensation assembly 5 contacts the cold air generated by the evaporator 3 and undergoes heat exchange condensation, so that the moisture in the air is fully condensed at the condensation assembly 5;

[0046] Among them, through the setting of the condensation component 5, after the air enters the shell 1 through the air inlet 11, part of the air is evaporated and dehumidified through the evaporator 3, and part of the air enters the condensation component 5 and contacts the cold air generated by the evaporator 3, so that after the air enters the condensation tube of the condensation component 5, the air in the hollow heat conduction tube 51 will be affected by the temperature difference between the inside and the outside and cool down to produce condensed water, so that the dehumidifier can produce more water through the condensation component 5 on the basis of the original evaporation and dehumidification of the evaporator 3; and under the same power consumption, the more water the dehumidifier produces, the higher its energy efficiency will be. It can be seen that when the condensation component 5 is installed on one side of the evaporator 3 and contacts the evaporator 3, it can help improve the overall dehumidification capacity of the dehumidifier. Therefore, the dehumidifier equipped with the condensation component 5 can effectively improve the energy efficiency of the dehumidifier itself and reduce the energy consumption of the dehumidifier; and the condensation component The setting of 5 does not change the structure of the original parts of the dehumidifier, so the dehumidifier can improve its own dehumidification energy efficiency without using a high-power compressor or increasing the area of ​​the heat exchanger, effectively avoiding the problem of the dehumidifier being too large in overall size and high production cost due to adjusting the compressor or heat exchanger; at the same time, because there is a gap between the radiator 6 and the condensation component 5, the radiator 6 will not affect the condensation effect of the condensation component 5 when it is working; the condensation component 5 with a special structure can make it possible to reduce the speed of air when entering the condensation pipe through the reversely set second connector 54 and the first connector 52 when introducing and exporting air, and prolong the flow time of the flowing air in the hollow heat conduction pipe 51, ensuring that the air can fully contact with the cold air generated by the evaporator 3 and perform heat exchange and cooling, so as to achieve sufficient cooling of the air and condensation of water vapor.

[0047] In this embodiment, the hollow heat pipe 51 is made of a heat-conducting metal pipe, preferably an aluminum pipe, so that the hollow heat pipe 51 can have good thermal conductivity, ensuring that when the air flows in the hollow heat pipe 51, it can exchange heat with the cold air generated by the evaporator 3, ensuring that the air can be fully cooled and condensed into condensed water; the outer shape of the shell 1 can be a cube or a cylinder, and a suitable shape can be selected according to actual needs, and there is no limitation here.

[0048] In this embodiment, the hollow heat pipe 51 can adopt a flat pipe design, which can increase the contact area between hot air and cold air in the hollow heat pipe 51, thereby achieving the purpose of increasing the cooling rate; the hollow heat pipe 51 described in this embodiment is not limited to a flat pipe design, and can also be a round tube or square tube design, as long as it meets the actual use requirements.

[0049] In this embodiment, the compressor is used to compress and transport the refrigerant to the evaporator 3, so that the evaporator 3 can generate cold air; in this embodiment, a refrigerant storage tank is also provided inside the shell 1 for storing the refrigerant, so that the compressor can compress the refrigerant and transport it to the evaporator 3 for use.

[0050] In a specific implementation of this embodiment, it also includes an electric control component 4, which is arranged in the housing 1 below the control panel 2 and is electrically connected to the control panel 2 for receiving control signals from the control panel 2 and controlling the operation of the dehumidifier.

[0051] In a specific implementation of this embodiment, it also includes a fan 7, which is arranged on a side of the radiator 6 away from the condensation component 5, and the fan 7 is electrically connected to the electronic control component 4; wherein the fan 7 can drive the air to enter the air duct from the air inlet 11, and after being cooled and dehumidified by the condensation component 5, the air flows out along the air duct to the air outlet 13, thereby achieving cooling and dehumidification of the air; in this embodiment, the fan 7 can be a centrifugal fan, or other air fans, as long as the air can flow in the air duct through its own rotation.

[0052] In a specific implementation of this embodiment, it also includes a water tank 8, which is arranged directly below the fan 7 and is used to collect the liquid condensed by the evaporator 3 and the condensation component 5; in this embodiment, a cavity 14 for accommodating the water tank 8 is provided inside the shell 1; wherein the cavity 14 is used to accommodate the water tank 8, and a side cover 12 is also provided on the shell 1 on one side of the cavity 14, so that the condensed water droplets generated by the evaporator 3 and the condensation component 5 can be collected in the water tank 8, and the opening of the side cover 12 can facilitate the cleaning of the condensed water in the water tank 8.

[0053] In order to clearly understand the dehumidification capacity and dehumidification energy efficiency of the dehumidifier, take a 250w dehumidifier working for one day in an environment with an ambient humidity of 27°C and an ambient humidity of 60% as an example, the water content of the water tank 8 after dehumidification of the dehumidifier without the condensation component 5 and the dehumidifier with the condensation component 5 is measured, and it is known that the dehumidification capacity of the dehumidifier without the condensation component 5 is 13.5L / day, and the dehumidification capacity of the dehumidifier with the condensation component 5 is 15.5L / day; then according to the energy efficiency calculation formula: EF (energy efficiency) = 1000*dehumidification capacity / (24*power), it can be known that the energy efficiency of the dehumidifier without the condensation component is 1000*13.5 / (24*250)=2.25L / kw.h, while the energy efficiency of the dehumidifier with the condensation component is 1000*15 .5 / (24*250)=2.583L / kw.h. It can be seen that the dehumidifier equipped with the condensing component 5 has higher energy efficiency and lower energy consumption.

[0054] Example 2

[0055] like Figure 3-6 As shown, in this embodiment, the No. 1 connector 52 and the No. 2 connector 54 are both provided with a connecting sleeve 53 for connecting the hollow heat pipe 51; wherein, the provision of the connecting sleeve 53 can improve the connectivity between the No. 1 connector 52 and the No. 2 connector 54 and the hollow heat pipe 51, ensuring that the No. 1 connector 52 and the No. 2 connector 54 can be stably connected to the hollow heat pipe 51.

[0056] Example 3

[0057] like Figure 3-5 As shown, in this embodiment, one side of the No. 2 connector 54 is connected to a mounting clamp rod 55, and the other side is provided with a clamping groove 58 matching the mounting clamp rod 55; wherein the No. 2 connector 54 can realize the disassembly and assembly between multiple No. 2 connectors 54 through the mutual cooperation of the mounting clamp rod 55 and the clamping groove 58, thereby realizing the assembly and use of multiple condensation tubes, so that the condensation assembly 5 can be adaptively adjusted according to the size of the evaporator 3 of the dehumidifier.

[0058] Example 4

[0059] like Figure 5 , 6 As shown, in this embodiment, a partition middle plate 57 is provided between the upper and lower ends of the air flow port 56; wherein, the provision of the partition middle plate 57 can effectively separate and guide the incoming and outgoing air, thereby achieving a deceleration of the flowing air, thereby extending the time of the flowing air in the hollow heat pipe 51, and ensuring that the air can be adequately cooled.

[0060] In summary, the present invention provides a dehumidifier with an auxiliary condensation structure. Through the contact setting of the condensation component 5 and the evaporator 3, after the air enters the dehumidifier, part of the air enters the evaporator 3 for dehumidification, and part of the air enters the condensation component 5, so that the air entering the condensation component 5 can contact the cold air generated by the evaporator 3 and undergo heat exchange condensation, so that the moisture in the air is fully condensed at the condensation component 5, and then the dehumidifier can produce more water through the condensation component 5 on the basis of the dehumidification of the original evaporator 3, thereby improving the energy efficiency of the dehumidifier, reducing the energy consumption of the dehumidifier, and effectively avoiding the problem of excessive overall size and high production cost of traditional dehumidifiers due to adjustment of the compressor or heat exchanger.
