[0048] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the dehumidifier includes a housing 100, a plurality of refrigeration parts 200 and a fan mechanism 300. The housing 100 is provided with an air outlet 110 and a plurality of air inlets 120 arranged side by side; the plurality of refrigeration parts 200 are arranged side by side in the housing 100 corresponding to the plurality of air inlets 120, each refrigeration part 200 includes two oppositely arranged refrigeration side surfaces 210, the two oppositely arranged refrigeration side surfaces 210 are respectively located on both sides of the air inlet 120, and the refrigeration side surfaces 210 are used to provide cooling capacity, and a cooling air duct 220 is arranged between the two oppositely arranged refrigeration side surfaces 210, and the cooling air duct 220 is connected between the air outlet 110 and the corresponding air inlet 120; the fan mechanism 300 is used to suck the airflow outside the housing 100 into the cooling air duct 220 through the plurality of air inlets 120 and then discharge it out of the housing 100 through the air outlet 110.

[0049] Since the dehumidifier of this embodiment has a refrigeration unit 200, each refrigeration unit 200 has two refrigeration sides 210 located on both sides of the air inlet 120 and arranged oppositely for providing coldness, and the two refrigeration sides 210 arranged oppositely are used to directly construct a cold supply air duct 220 connected to the air inlet 120. Compared with the prior art, the dehumidifier of the present invention does not need to set up a larger air duct to place the dehumidification component, and under the action of the fan mechanism 300, the airflow will completely flow through the cold supply air duct 220, and the coldness provided by the refrigeration side 210 will cool down the condensed water and remove the water in the airflow, thereby realizing the dehumidification process. Compared with the prior art, the effective airflow volume cooled by the dehumidification component (cold supply air duct 220) will be greatly increased. Therefore, this embodiment can allow the dehumidifier to have a smaller volume, and ensure the dehumidification capacity and dehumidification performance of the dehumidifier, thereby improving the user experience.

[0050] Furthermore, since the dehumidifier of this embodiment has multiple air inlets 120 and refrigeration units 200, and multiple cooling air ducts 220 are arranged side by side, when the total air inlet area of ​​the air inlet 120 and the cooling air duct 220 is constant, the contact area between the airflow flowing through the cooling air duct 220 and the refrigeration side surface 210 will be further increased. Therefore, the dehumidification performance of the dehumidifier of this embodiment can be further improved.

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In the present embodiment, the dehumidifier further includes a plurality of heating parts 400, and the plurality of heating parts 400 are arranged side by side in the shell 100, and each heating part 400 includes two oppositely arranged heating sides 410, and the heating sides 410 are used to provide heat, and a heating air duct 420 is arranged between the two oppositely arranged cooling sides 210, and the heating air duct 420 is connected between the cooling air duct 220 and the air outlet 110; and the fan mechanism 300 is also used to guide the airflow after flowing into the cooling air duct 220 to flow through the heating air duct 420 and then be discharged from the shell 100 through the air outlet 110.

[0052] It can be understood that since the airflow, after being cooled by the cooling air duct 220, is directly discharged from the shell 100 to the indoor space, the ambient temperature of the indoor space will be lowered. Therefore, through the setting of the refrigeration unit 200 and the heating air duct 420, under the action of the fan mechanism 300, the cooled airflow will also flow through the heating air duct 420 and be heated, and finally flow into the indoor space, so as to effectively avoid the dehumidified airflow being discharged into the indoor space and affecting the ambient temperature of the indoor space, thereby ensuring the comfort level of the ambient temperature of the indoor space.

[0053] Reference Figure 3 and Figure 5 In this embodiment, the fan mechanism 300 is also used to suck the airflow outside the shell 100 into the heating air duct 420 through the air inlet 120, and guide the airflow to flow through the cooling air duct 220 and then be discharged from the shell 100 through multiple air inlets 120.

[0054] It is understandable that when the dehumidifier is in continuous operation, frost may form on the refrigeration part 200, thereby affecting the cooling effect of the refrigeration side 210 on the airflow, greatly reducing the dehumidification performance of the dehumidifier. Furthermore, in this embodiment, the fan mechanism 300 can also cause the airflow outside the shell 100 to be first sucked into the heating air duct 420 through the air outlet 110 and then heated, and then flow through the cooling air duct 220 to defrost the two opposite refrigeration sides 210 of the refrigeration part 200, and finally be discharged from the shell 100 through multiple air inlets 120, thereby realizing the defrosting process to ensure the normal dehumidification function of the dehumidifier and the dehumidification performance of the dehumidifier.

[0055] In addition, when the dehumidifier is operating the defrosting function, the heating unit 400 may not operate.

[0056] Reference Figure 3 In this embodiment, a plurality of heating units 400 and a plurality of cooling units 200 are arranged alternately, so that the heating air ducts 420 and the cooling air ducts 220 are arranged alternately side by side.

[0057] It can be understood that by arranging a plurality of heating parts 400 and a plurality of cooling parts 200 alternately, so that the heating air duct 420 and the cooling air duct 220 are alternately arranged side by side, the heating part 400 (heating air duct 420) and the cooling part 200 (cooling air duct 220) can be highly integrated together, and such a clever and reasonable design can further reduce the space occupied by the cooling part 200 and the heating part 400. Therefore, this embodiment can further allow the dehumidifier to have a smaller volume and improve the user experience.

[0058] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the air outlet 110 is located at the top of the shell 100, and multiple air inlets 120 are arranged on the front side of the shell 100 along the left-right direction, and each air inlet 120 extends in the up-down direction. A connecting air cavity 130 connecting the heating air duct 420 and the cooling air duct 220 is provided in the shell 100. The connecting air cavity 130 includes a first connecting cavity 131 and a second connecting cavity 132 that are connected to each other. The first connecting cavity 131 is located behind the cooling air duct 220, and the second connecting cavity 132 is located behind the multiple heating air ducts 420.

[0059] It can be known that, by setting the connecting air cavity 130 and its position, the airflow can flow through the entire cooling air duct 220 and then enter the heating air duct 420, thereby ensuring the cooling effect of the refrigeration unit 200 on the airflow flowing through the cooling air duct 220, avoiding the waste of cold energy and ensuring the dehumidification performance of the dehumidifier.

[0060] Reference Figure 4 or Figure 5 In this embodiment, the rear wall of the first connecting cavity 131 and the top wall of the first connecting cavity 131, the rear wall of the first connecting cavity 131 and the bottom wall of the second connecting cavity 132, and the front wall of the second connecting cavity 132 and the bottom wall of the second connecting cavity 132 are all connected by an arc wall 160.

[0061] It can be understood that, by setting the arc wall 160, the airflow can be well guided when the dehumidifier in the following embodiments is running the dehumidification function and the defrost function, effectively avoiding the loss of the airflow during the flow process, and ensuring the dehumidification performance of the dehumidifier.

[0062] In some variant embodiments, the dehumidifier includes a condenser and an evaporator, and the condensing fins of the condenser are arranged side by side in the left-right direction in the housing 100, and each condensing fin of the condenser is arranged in the up-down direction, and a heating part 400 is formed between two adjacent condensing fins, and two oppositely arranged heating sides 410 are two opposite sides of two adjacent condensing fins; the evaporating fins of the evaporator are arranged side by side in the left-right direction in the housing 100, and each evaporating fin of the evaporator is arranged in the up-down direction, and a refrigerating part 200 is formed between two adjacent evaporating fins, and two oppositely arranged heating sides 410 are two opposite sides of two adjacent evaporating fins. Then, the construction of the refrigerating part 200, the refrigerating side 210, the heating part 400, and the heating side 410 in the above embodiments can be realized to achieve the beneficial technical effects described in some of the above embodiments.

[0063] In order to make the dehumidifier have a smaller volume, the condensing fins and the evaporating fins can be arranged alternately in pairs, so that the heating part 400 (heating air duct 420) and the refrigeration part 200 (cooling air duct 220) can be highly integrated to achieve the beneficial technical effects of the above embodiment.

[0064] In some other variant embodiments, the difference from the above variant embodiments is that the condenser can be replaced by an electric heating structure including heating fins. Similarly, the beneficial technical effects described in the above embodiment can be achieved.

[0065] Reference Figure 2 and Figure 3 In this embodiment, the dehumidifier includes a plurality of semiconductor refrigeration sheets 500, which are stacked side by side in the left-right direction in the shell 100, and each semiconductor refrigeration sheet 500 is arranged in the up-down direction, the cooling side 210 is the cooling end surface of the semiconductor refrigeration sheet 500, and the heating side 410 is the heat dissipation end surface of the semiconductor refrigeration sheet 500.

[0066] It can be understood that by alternating the cooling end faces and the heat dissipation end faces of multiple semiconductor cooling plates 500, the construction of the cooling part 200, the cooling side 210, the heating part 400, and the heating side 410 in the above embodiments can be realized to achieve the beneficial technical effects described in the above embodiments.

[0067] At the same time, this embodiment makes full use of the heat dissipation end of the semiconductor cooling sheet 500, and there is no need to separately set up an additional heating mechanism (such as the condenser of the aforementioned variant embodiment) to save the energy consumed by the additional heating mechanism, ensure the energy saving of the dehumidifier, and further reduce the width of the highly integrated heating part 400 (heating air duct 420) and the cooling part 200 (cooling air duct 220). Therefore, this embodiment can further allow the dehumidifier to have a smaller volume and improve the user experience; in addition, compared with heat exchange components such as condensers and evaporators, the semiconductor cooling sheet 500 itself does not need to be provided with a heat-conducting copper tube or other structures that are passed through the fins. The space volume occupied by the semiconductor cooling sheet 500 can be smaller, which can further allow the dehumidifier to have a smaller volume and improve the user experience. It should also be noted that the dehumidifier can have a smaller volume. In other words, compared with the existing structure, the number of semiconductor cooling sheets 500 can be set more under the same equipment volume to effectively ensure the dehumidification performance of the dehumidifier and improve the user experience.

[0068] Moreover, compared with the aforementioned modified embodiments or the prior art, the present embodiment utilizes semiconductor refrigeration plates 500 to construct the refrigeration section 200, the refrigeration side 210, the heating section 400, and the heating side 410, and does not provide components such as heat-conducting fins, thereby reducing the heat loss between the semiconductor refrigeration plates 500 and the fins. The airflow in the cooling air duct 220 and the heating air duct 420 can directly contact the refrigeration end surface or the heat dissipation end surface of the semiconductor refrigeration plates 500, thereby ensuring the cooling and heating effects of the dehumidifier.

[0069] Reference Figure 2 and Figure 3 In this embodiment, the left and right side plates of the housing 100 may be the leftmost and rightmost semiconductor cooling plates 500 among a plurality of semiconductor cooling plates 500 arranged in the left-right direction.

[0070] Furthermore, the number of semiconductor refrigeration sheets 500 can be 59. Such a number of semiconductor refrigeration sheets 500 can well meet the dehumidification performance requirements of users of dehumidifiers in the home field, and this number of semiconductor refrigeration sheets 500 can form 29 cooling air ducts 220 and 29 heating air ducts 420, and then the left and right end surfaces of the shell 100 can be the cooling end surface and the heat dissipation end surface of the semiconductor refrigeration sheet 500, respectively.

[0071] Reference Figure 2 and Figure 3In this embodiment, the semiconductor cooling sheet 500 may have a length L of 150 mm, a width M of 150 mm, and a thickness K of 4 mm. The semiconductor cooling sheet 500 of this size can well meet the volume and dehumidification performance requirements of users of dehumidifiers in the home field. The distance H between any two semiconductor cooling sheets 500 may be 1.25 mm, so as to effectively ensure the cooling effect and heating effect of the cooling air duct 220 and the heating air duct 420 on the air flow passing through.

[0072] In this embodiment, the dehumidifier includes a temperature sensor, which is arranged on the semiconductor refrigeration chip 500 to monitor the temperature of the semiconductor refrigeration chip 500. When the temperature of the semiconductor refrigeration chip 500 is within the set temperature range of frosting, the dehumidifier starts to run the dehumidification function.

[0073] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the housing 100 includes a front panel 140 located at the front side thereof, and a plurality of air inlets 120 are located on the front panel 140; the dehumidifier further includes a first air duct baffle 610 and a second air duct baffle 620, the first air duct baffle 610 is disposed in the housing 100, the first air duct baffle 610 is shielded below the plurality of semiconductor cooling sheets 500, and a heat through hole 610 connected to the second connecting cavity 132 is provided at a position corresponding to the heating air duct 420 on the first air duct baffle 610 1; the second air duct baffle 620 is arranged in the shell 100, the second air duct baffle 620 blocks the top of the plurality of semiconductor cooling sheets 500, and an air supply hole 621 connected to the air outlet 110 is opened on the second air duct baffle 620 at a position corresponding to the heating air duct 420; and the cooling air duct 220 is located between the first air duct baffle 610, the second air duct baffle 620 and the two cooling side surfaces 210; the heating air duct 420 is located between the front panel 140 and the two heating side surfaces 410.

[0074] It can be understood that, by setting the front side plate, the first air duct baffle 610 and the second air duct baffle 620, the construction of the above-mentioned cooling air duct 220 and the heating air duct 420 is realized, the connection between the cooling air duct 220 and the first connecting chamber 131 in the above-mentioned embodiment, the connection between the heating air duct 420, the first connecting chamber 131, the second connecting chamber 132 and the air supply chamber 150 of the following embodiment, and the requirement of the above-mentioned embodiment to first enter the cooling air duct 220 through the air inlet 120; at the same time, It is found that during the dehumidification process of the dehumidifier, the airflow flows in sequence along the flow path of the air inlet 120, the cooling air duct 220, the first connecting chamber 131 (, the second connecting chamber 132), the heating air duct 420, and the air outlet 110, thereby ensuring the normal operation of the dehumidification function of the dehumidifier, or the airflow flows in sequence along the flow path of the air outlet 110, the heating air duct 420, (the second connecting chamber 132,) the first connecting chamber 131, and the air inlet 120, thereby ensuring the normal operation of the defrosting function of the dehumidifier.

[0075] In the modified embodiment, the difference from the above embodiment is that the dehumidifier also includes a third air duct baffle, which is arranged in the shell 100, the third air duct baffle is arranged relative to the front panel 140, and the third air duct baffle is located behind the multiple semiconductor refrigeration plates 500, and a cooling hole connected to the first connecting cavity 131 is arranged on the third air duct baffle corresponding to the cooling air duct 220; the heating air duct 420 is located between the third air duct baffle, the front panel 140 and the two heating sides 410.

[0076] It can be understood that, by setting the third air duct baffle, the connection of the heating air duct 420 through the first connecting chamber 131 is blocked, and then during the dehumidification process of the dehumidifier, the air flow will flow in sequence according to the flow path of the air inlet 120, the cooling air duct 220, the first connecting chamber 131, the second connecting chamber 132, the heating air duct 420, and the air outlet 110, thereby ensuring the normal operation of the dehumidification function of the dehumidifier, or the air flow will flow in sequence according to the flow path of the air outlet 110, the heating air duct 420, the second connecting chamber 132, the first connecting chamber 131, the cooling air duct 220, and the air inlet 120, thereby ensuring the defrosting function of the dehumidifier Normal operation; at the same time, the setting of the third air duct wind shield can effectively avoid interference between the airflow flowing from the cooling air duct 220 through the first connecting chamber 131 to the heating air duct 420 during the operation of the dehumidification function of the dehumidifier, and the airflow flowing from the cooling air duct 220 through the first connecting chamber 131 and the second connecting chamber 132 to the heating air duct 420, and avoid interference between the airflow flowing from the heating air duct 420 through the first connecting chamber 131 to the cooling air duct 220 during the operation of the defrost function of the dehumidifier, and the airflow flowing from the heating air duct 420 through the second connecting chamber 132 and the first connecting chamber 131 to the cooling air duct 220.

[0077] Reference Figure 6 , Figure 7 and Figure 8 In this embodiment, the front side plate, the first air duct baffle 610, the second air duct baffle 620 (and the third air duct baffle) are all provided with limiting protrusions 630 arranged along the arrangement direction of the plurality of semiconductor cooling sheets 500, and the limiting protrusions 630 are used to maintain the distance between the semiconductor cooling sheets 500.

[0078] Reference Figure 2 and Figure 4 In this embodiment, the fan mechanism 300 includes a cross-flow fan 310 ; and, an air supply cavity 150 communicating with the air supply hole 621 and the air outlet 110 is further provided in the housing 100 , and the cross-flow fan 310 is rotatably disposed in the air supply cavity 150 .

[0079] It can be understood that in this embodiment, the housing 100 directly forms the air duct structure of the fan mechanism 300. Under such a structure, the dehumidifier can switch the flow direction of the airflow in the dehumidification function and the defrost function by switching the forward and reverse rotation of the fan mechanism 300. In addition, the fan mechanism 300 can also be a fan mechanism 300 independent of the housing 100, by connecting the fan air inlet 120 of the fan mechanism 300 to the air outlet 110, or connecting the fan air outlet 110 of the fan mechanism 300 to the air inlet 120. The dehumidifier can also switch the flow direction of the airflow in the dehumidification function and the defrost function by switching the forward and reverse rotation of the fan mechanism 300; the dehumidifier can also add components such as a flip mechanism to drive the fan air inlet 120 and the fan air outlet 110 to interchange and connect, so as to achieve the switching of the flow direction of the airflow in the dehumidification function and the defrost function.

[0080] Furthermore, when the dehumidifier is operating the dehumidification function, the rotation speed of the fan mechanism 300 can be 1400 rpm to ensure the dehumidification effect of the dehumidifier.

[0081] In addition, the fan mechanism 300 can be set to three speed gears of high, medium and low. The high wind speed can be 1680 rpm, the medium wind speed can be 1400 rpm, and the low wind speed can be 610 rpm, so that the dehumidifier can provide different air volumes, so that the dehumidifier has more working conditions and effectively meets the user's usage scenarios and the use of multiple types of users.

[0082] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment, the dehumidifier includes a water storage tank 700, which is disposed at the bottom of the housing 100, and the top of the water storage tank 700 is connected to the cooling air duct 220. The water storage tank 700 is used to receive condensed water cooled in the air flow in the cooling air duct 220. Furthermore, the dehumidifier of this embodiment can prevent condensed water from leaking into the indoor space during operation, thereby ensuring the user experience of the dehumidifier.

[0083] In addition, the top of the water storage barrel 700 is connected to the cooling air duct 220 by connecting to the air cavity 130. When the dehumidifier is operating the dehumidification function, condensed water in the cooling air duct 220 or water after the frost in the cooling air duct 220 melts when the dehumidifier is operating the defrosting function can flow along the cooling air duct 220 through the connecting air cavity 130 and enter the water storage barrel 700.
