Description

Technical Field

[0001] The utility model belongs to the field of fresh air, and particularly relates to a dehumidifying device with switchable air intake. Background Art

[0002] The dehumidifying device is used to dry the air entering the room from the outside, and is widely used in daily life.

[0003] At present, the dehumidifying device includes a condensing pipe and a regeneration runner. The condensing pipe condenses the air entering from the outside, and then adsorbs moisture through the regeneration runner to achieve the dehumidification function. And this method can also remove certain pollutants contained in the air, but this way of pollutant removal cannot completely remove all pollutants. Therefore, the air entering the room from the dehumidifying device often contains pollutants that have not been eliminated in time. Therefore, when people stay in such an environment for a long time, they are easily affected by the above-mentioned microorganisms, causing health problems such as cough, asthma and respiratory infections. Therefore, dehumidifying devices with self-disinfection functions have emerged on the market. Among them, ultraviolet lamp disinfection has become a common method of disinfection because of its high sterilization efficiency, no side effects, small floor area, and deodorizing effect. However, the air flow of the existing dehumidifying device passing through the ultraviolet lamp has a short time, resulting in the dried gas not reaching the effective ultraviolet lamp irradiation time, so that the disinfection effect cannot be well achieved. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a dehumidifying device with switchable air intake, which can significantly reduce the pollutants entering the room from the dehumidifying device.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A dehumidifying device with switchable air intake is used to dry the humid air entering from the outdoor side and output dry air to the indoor side. It is characterized in that it includes: a casing having a dehumidification inlet and a dehumidification outlet, the dehumidification outlet opening to the indoor side, and taking the direction from the dehumidification inlet to the dehumidification outlet in the casing as the drying direction; a molecular sieve runner rotatably arranged inside the casing; a condensing pipe group and a regeneration component, the condensing pipe group and the molecular sieve runner are arranged in sequence along the drying direction. The molecular sieve runner has a dehumidification area and a regeneration area that are cyclically converted by rotation. The humid air passes through the dehumidification area and is adsorbed with moisture to form dry air. The regeneration component includes a regeneration fan that blows hot air towards the regeneration area, and the hot air evaporates and blows out the moisture in the regeneration area. Among them, the dehumidifying device with switchable air intake further includes a two-way three-way valve, and the indoor side and the outdoor side are selectively connected to the dehumidification inlet through the two-way three-way valve.

[0007] Preferably, the present utility model further includes a disinfection unit. The two-way three-way valve is communicated with the dehumidification inlet through the disinfection unit. The disinfection unit has a disinfection housing, and the disinfection housing is formed with a disinfection inlet, a disinfection outlet, and a gas retention channel. The gas retention channel extends circuitously, and the disinfection inlet and the disinfection outlet are communicated through the gas retention channel. And an ultraviolet disinfection lamp is hung on the inner wall of the gas retention channel. The disinfection inlet is communicated with the two-way three-way valve, and the disinfection outlet is communicated with the dehumidification inlet.

[0008] Preferably, the disinfection unit further includes a plurality of circuitous baffles. The plurality of circuitous baffles are all located inside the disinfection housing. The plurality of circuitous baffles form a plurality of circuitous openings in the inner cavity of the disinfection housing by blocking, and the plurality of circuitous openings are staggered, thereby forming a circuitously extending gas retention channel. The ultraviolet disinfection lamp is hung on the surface of the circuitous baffle.

[0009] Further, the disinfection inlet is larger than the disinfection outlet, and the disinfection unit further has a disinfection guide fan, and the disinfection guide fan is arranged at the disinfection inlet.

[0010] Further, the present utility model further includes a communication module, a control module, and a user terminal. The control module is signal-connected to the two-way three-way valve, the communication module is signal-connected to the control module, the user terminal is used to send a switching signal, the communication module is used to receive the switching signal and transmit it to the control module, and the control module is used to control the two-way three-way valve to act, so as to alternatively connect the indoor side with the disinfection inlet and the outdoor side with the disinfection inlet.

[0011] Preferably, the condenser tube group includes a water receiving shell and a coiled condenser tube fixed inside the water receiving shell. The water receiving shell is fixed inside the machine shell. The coiled condenser tube is hollow and its outer surface is continuous with the inner wall of the water receiving shell. The coiled condenser tube is communicated with the cold water supply end of an external air source heat pump through the internal channel of the water receiving shell.

[0012] Further, both ends of the coiled condenser tube are communicated with the external air source heat pump through the internal channel of the water receiving shell, so that cold water continuously flows into the coiled condenser tube from the air source heat pump as a refrigerant to exchange heat and condense the humid air flowing through. The cold water heated in the coiled condenser tube finally flows back to the air source heat pump.

[0013] Preferably, the present utility model further includes an inner shell bracket and a driving motor. The inner shell bracket is fixed inside the machine shell. The axes of the driving motor and the molecular sieve rotor are parallel and are rotatably arranged on the inner shell bracket. A tension wheel is fixed on the output shaft of the driving motor, and the tension wheel and the molecular sieve rotor are synchronously driven by a synchronous belt.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. Since the dehumidifying device with switchable intake air of the present utility model includes a casing, a molecular sieve rotor, a condensing tube group, a regeneration assembly and a two-position three-way valve, the casing has a dehumidifying inlet, a dehumidifying outlet and a drying direction. The molecular sieve rotor is rotatably arranged inside the casing. The condensing tube group and the molecular sieve rotor are arranged in sequence along the drying direction. The molecular sieve rotor has a dehumidifying area and a regeneration area that are cyclically converted by rotation. Moist air passes through the dehumidifying area and is adsorbed with moisture to form dry air. The regeneration assembly includes a regeneration fan that blows hot air towards the regeneration area. The hot air evaporates and blows out the moisture in the regeneration area. The indoor side and the outdoor side are selectively connected to the dehumidifying inlet through the two-position three-way valve. Therefore, after the present utility model operates for a predetermined time, it can perform intake air conversion between the outdoor side and the indoor side. And the indoor side has had pollutants removed in the dehumidifying device for a predetermined time relative to the outdoor side, so it contains fewer pollutants than the outdoor side air. Thus, compared with the dehumidifying device that only introduces air from the outdoor side, the present utility model can significantly reduce the pollutants entering the indoor side of the dehumidifying device.

[0016] 2. Since the present utility model further includes a disinfection unit, the two-position three-way valve is connected to the dehumidifying inlet through the disinfection unit. The disinfection unit has a disinfection casing, and the disinfection casing is formed with a disinfection inlet, a disinfection outlet and a gas retention channel. The gas retention channel extends circuitously. The disinfection inlet and the disinfection outlet are connected through the gas retention channel, and an ultraviolet disinfection lamp is hung on the inner wall of the gas retention channel. The disinfection inlet is connected to the two-position three-way valve, and the disinfection outlet is connected to the dehumidifying inlet. Therefore, the present utility model makes the air stay in the disinfection casing for a longer time through the circuitously extending gas retention channel, thereby prolonging the irradiation time of the ultraviolet lamp on the gas in the gas retention channel, and further achieving a better disinfection effect.

[0017] 3. Since the disinfection inlet of the present utility model is larger than the disinfection outlet, the intake air volume of the present utility model is larger than the outlet air volume, thereby further increasing the time for the air to stay in the disinfection casing.

[0018] 4. Since both ends of the coiled snake condensing tube of the present utility model are connected to an external air source heat pump through the internal channel of the water receiving shell, the coiled snake condensing tube continuously flows in cold water from the air source heat pump as a refrigerant to exchange heat and condense the moist air flowing through it. The cold water heated in the coiled snake condensing tube finally flows back to the air source heat pump. Therefore, before the molecular sieve rotor of the present utility model dries the moist air, cold water provided by the external air source heat pump is used as a refrigerant, and the coiled snake condensing tube is used to perform condensation pre-drying on the moist air to be dried, thereby significantly improving the dehumidifying effect.

Detailed implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following embodiments are used to specifically illustrate the dehumidification device with air intake switchable of the present utility model in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are used to help understand the present utility model, but do not constitute a limitation to the present utility model.

[0026] As Figure 1 shown, the dehumidification device 100 with air intake switchable in this embodiment is used to dry the humid air entering from the outdoor side and output dry air to the indoor side.

[0027] The dehumidification device 100 with air intake switchable includes a housing 10, a driving motor 20, a molecular sieve rotor 30, a condenser tube group 40, a regeneration component 50, a two-way three-way valve V, a communication module (not shown in the drawings), a control module (not shown in the drawings), a user terminal (not shown in the drawings), and a disinfection unit 60.

[0028] Either the indoor side or the outdoor side is communicated with the disinfection unit 60 through the two-way three-way valve V, and the two-way three-way valve V is communicated with the housing 10 through the disinfection unit 60, and the housing 10 is open to the indoor side.

[0029] The control module is signal-connected to the two-position three-way valve V, the communication module is signal-connected to the control module, the user terminal is used to send a switching signal, the communication module is used to receive the switching signal and transmit it to the control module, and the control module is used to control the operation of the two-position three-way valve V, so as to alternatively connect the indoor side to the disinfection unit 60 and the outdoor side to the disinfection unit 60. In this embodiment, the user issues a switching signal by manually operating the user terminal.

[0030] As Figure 2 shown, the disinfection unit 60 has a disinfection housing 61, a bypass baffle 62, an ultraviolet disinfection lamp 63, and a disinfection guide fan 64.

[0031] The disinfection housing 61 is hollow, and a disinfection inlet 61a and a disinfection outlet 61b are respectively formed on opposite sides of the surface of the disinfection housing 61. The disinfection inlet 61a is communicated with the two-position three-way valve V, and the disinfection outlet 61b is communicated with the housing 10.

[0032] The number of the bypass baffles 62 is multiple. The multiple bypass baffles 62 are all located inside the disinfection housing 61. The multiple bypass baffles 62 form a plurality of bypass openings 62a in the inner cavity of the disinfection housing 61 by blocking. The plurality of bypass openings 62a are staggered, so as to form a bypass-extending stagnant air channel (not shown in the drawing), and the disinfection inlet 61a and the disinfection outlet 61b are communicated through the stagnant air channel. In this embodiment, the inner cavity of the disinfection housing 61 is in a rectangular shape, the bypass baffle 62 is in a rectangular plate shape, the bypass baffle 62 is arranged between the opposite inner side walls of the disinfection housing 61, and one end of the bypass baffle 62 is continuously closed with one inner side wall of the disinfection housing 61, and the other end is spaced from one inner side wall of the disinfection housing 61 by a predetermined space, so as to form a bypass opening 62a. Thus, the bypass openings 62a are staggered in the corresponding directions of the multiple bypass baffles 62. Furthermore, the multiple bypass baffles 62 divide the inner cavity of the disinfection housing 61 into a bypass-extending stagnant air channel, and when the gas flows out of the disinfection housing 61 through the stagnant air channel, it stays for a longer time.

[0033] The passing area of the disinfection inlet 61a is larger than the passing area of the disinfection outlet 61b, so that the amount of gas flowing through the disinfection inlet 61a in the same time is greater than the amount of gas flowing through the disinfection outlet 61b, thereby further increasing the residence time of the gas when flowing out of the disinfection housing 61 through the stagnant air channel.

[0034] The ultraviolet disinfection lamp 63 is hung on the surface of the bypass baffle 62. Specifically, the ultraviolet disinfection lamps 63 are hung on the opposite two side surfaces of each bypass baffle 62.

[0035] The disinfection guide fan 64 is arranged at the disinfection inlet 61a.

[0036] As Figure 3As shown in the figure, the casing 10 has a dehumidification inlet 11, a dehumidification outlet 12, and a dehumidification diversion fan 13. The dehumidification outlet 11 is opened to the indoor side through the disinfection unit 60 and the two-way three-way valve V. The direction from the dehumidification inlet 11 to the dehumidification outlet 12 inside the casing 10 is defined as the drying direction D. Specifically, the dehumidification diversion fan 13 is arranged at the dehumidification inlet 11, and the dehumidification inlet 11 communicates with the disinfection outlet 61b.

[0037] Specifically, the condenser tube group 40 and the molecular sieve rotor 30 are arranged in sequence along the drying direction D.

[0038] As Figure 4 shown in the figure, the condenser tube group 40 includes a water receiving shell 41 and a coiled condenser tube 42.

[0039] The inner cavity of the water receiving shell 41 is open upward. The coiled condenser tube 42 is hollow and its outer surface is continuous with the inner wall of the water receiving shell 41. The coiled condenser tube 42 communicates with the cold water supply end P1 of an external air source heat pump through the internal channel (not shown in the drawings) of the water receiving shell 41.

[0040] Both ends of the coiled condenser tube 42 communicate with the external air source heat pump through the internal channel of the water receiving shell 41. Thus, the coiled condenser tube 42 continuously receives the fluid as the refrigerant from the air source heat pump, condenses the external air flow passing through it. The fluid after heat exchange in the coiled condenser tube 4 finally returns to the air source heat pump through the cold water return end P2. Specifically, the outer surface of the casing 10 has two quick connectors P3. The air source heat pump has an outflow end (not shown in the drawings) and a return end (not shown in the drawings). The outflow end communicates with one quick connector P3, this quick connector P3 communicates with one end of the coiled condenser tube 42, the other end of the coiled condenser tube 42 communicates with the other quick connector P3, and the other quick connector P3 communicates with the cold water return end P2.

[0041] As Figure 5 shown in the figure, the molecular sieve rotor 30 is rotatably arranged inside the casing 10 and is arranged across the drying direction D. The molecular sieve rotor 30 has a dehumidification area 30a and a regeneration area 30b that are cyclically converted by rotation. Specifically, for the continuous use of the molecular sieve rotor 30, the molecular sieve rotor 30 after adsorbing moisture should be evaporated and dehydrated so that the molecular sieve rotor 30 can return to the dry state. The relative positions of the dehumidification area 30a and the regeneration area 30b with respect to the casing 10 remain unchanged, and the molecular sieve rotor 30 rotates to cyclically convert the dehumidification area 30a and the regeneration area 30b.

[0042] Specifically, an inner bracket of the casing (not shown in the drawings) is also fixedly provided inside the casing 10. The axes of the driving motor 20 and the molecular sieve rotor 30 are parallel and are rotatably arranged on the inner bracket of the casing. A tension pulley (not shown in the drawings) is fixedly provided on the output shaft of the driving motor 20. Synchronous transmission is achieved between the circumference of the tension pulley and the circumference of the molecular sieve rotor 30 by winding a synchronous belt (not shown in the drawings). Thus, the driving motor 20 drives the molecular sieve rotor 30 to rotate by rotation.

[0043] The regeneration assembly 50 includes a regeneration housing 51, a regeneration fan 52, and a heating wire 53.

[0044] One end of the regeneration housing 51 covers the regeneration area 32, and the other end is open to the outside of the housing 10. Specifically, the regeneration housing 51 is located between the molecular sieve rotor 30 and the dehumidification outlet.

[0045] Both the heating wire 53 and the regeneration fan 52 are located inside the regeneration housing 51. The heating wire 53 is used to heat the air inside the regeneration housing 51, and the regeneration fan 52 is used to blow the heated air through the regeneration area 30b. Specifically, the air sequentially flows through the heating wire 53 and the regeneration fan 52 inside the regeneration housing 51, that is, the regeneration fan 52 is closer to the regeneration area 23b inside the regeneration housing 51.

[0046] Specifically, the regeneration assembly 50 further includes a moisture discharge channel 54. The moisture discharge channel 54 and the regeneration housing 51 are respectively located on opposite sides of the regeneration area 23b. One end of the moisture discharge channel 54 covers the regeneration area 32, and this end corresponds to the end of the regeneration housing 51 facing each other, that is, the regeneration fan 52 blows hot air towards the regeneration area 32. The hot air evaporates the moisture in the regeneration area 30b containing moisture and blows it into the interior of the moisture discharge channel 54. In this embodiment, the other end of the moisture discharge channel 54 is open to the outside of the housing 10, that is, the gas mixed with moisture is discharged to the outside of the housing 10.

[0047] The above embodiments are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by those of ordinary skill in the art without creative labor within the scope of the appended claims still fall within the protection scope of this patent.
