Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a dehumidifier. Background Technology

[0002] Air conditioning equipment, used in work, life, and entertainment, is becoming increasingly popular among users, and its market share is also growing. Examples include air conditioners, dehumidifiers, and humidifiers. Dehumidifiers, in particular, effectively provide people with a suitable humidity environment.

[0003] Currently, existing dehumidifiers all have large air ducts inside their casings, and dehumidification components are arranged inside the air ducts. This results in a large overall size of the dehumidifier, but the effective airflow through the dehumidification components is small, which further leads to a small dehumidification capacity and poor dehumidification performance, greatly reducing the user experience. Summary of the Invention

[0004] One object of the present invention is to provide a dehumidifier that can solve at least one of the defects in the prior art.

[0005] A further objective of this invention is to allow dehumidifiers to have a smaller size while maintaining their dehumidification capacity and performance, thereby improving the user experience.

[0006] Specifically, the present invention provides a dehumidifier, comprising:

[0007] The housing has an air outlet and multiple air inlets arranged side by side.

[0008] Multiple refrigeration units are arranged side by side in the housing, corresponding to multiple air inlets. Each refrigeration unit includes two oppositely arranged refrigeration sides, which are located on both sides of the corresponding air inlet. The refrigeration sides are used to provide cooling capacity. A cooling air duct is provided between the two oppositely arranged refrigeration sides, and the cooling air duct is connected between the air outlet and the corresponding air inlet.

[0009] The fan mechanism is used to draw airflow from outside the casing into the cooling duct through multiple air inlets and then discharge it from the casing through the air outlet.

[0010] Furthermore, dehumidifiers also include:

[0011] Multiple heating elements are arranged side-by-side within the housing. Each heating element includes two opposing heating sides and a cooling side for providing heat. A heating air duct is provided between the two opposing cooling sides, and the heating air duct connects to the cooling air duct and the air outlet.

[0012] The fan mechanism is also used to guide the airflow that flows into the cooling duct through the heating duct and then out of the casing through the air outlet.

[0013] Furthermore, the fan mechanism is also used to draw airflow from outside the casing into the heating duct through the air outlet, and guide the airflow through the cooling duct before discharging it from the casing through multiple air inlets.

[0014] Furthermore, multiple heating units and multiple cooling units are arranged alternately, so that heating air ducts and cooling air ducts are arranged alternately side by side.

[0015] Furthermore, the air outlet is located at the top of the housing, and multiple air inlets are arranged in the left-right direction on the front side of the housing, with each air inlet extending in the up-down direction. The housing is provided with a connecting air cavity that connects the heating air duct and the cooling air duct. The connecting air cavity includes a first connecting cavity and a second connecting cavity that are connected to each other. The first connecting cavity is located behind the cooling air duct, and the second connecting cavity is located behind the multiple heating air ducts.

[0016] Furthermore, the rear wall and top wall of the first connecting cavity, the rear wall of the first connecting cavity and the bottom wall of the second connecting cavity, and the front wall of the second connecting cavity and the bottom wall of the second connecting cavity are all connected by arc-shaped walls.

[0017] Furthermore, dehumidifiers include:

[0018] Multiple thermoelectric coolers are stacked side-by-side in the housing along the left-right direction, and each thermoelectric cooler is arranged in the up-down direction. The cooling side is the cooling end face of the thermoelectric cooler, and the heating side is the heat dissipation end face of the thermoelectric cooler.

[0019] Furthermore, the housing includes a front panel located on its front side, and multiple air inlets are located on the front panel;

[0020] Dehumidifiers also include:

[0021] The first air duct baffle is set inside the housing, shielding the area below multiple semiconductor cooling chips, and a heat-through hole is opened on it corresponding to the position of the heating air duct, which connects to the second connecting cavity.

[0022] The second air duct baffle, located inside the housing, shields the area above multiple semiconductor cooling chips, and has air supply holes corresponding to the heating air duct positions, connecting to the air outlet; furthermore...

[0023] The cooling air duct is located between the first air duct baffle, the second air duct baffle, and the two cooling sides;

[0024] The heating duct is located between the front panel and the two heating sides.

[0025] Furthermore, the fan mechanism includes a cross-flow fan; and,

[0026] The housing also has an air supply cavity that connects the air supply hole and the air outlet, and the cross-flow fan is rotatably installed in the air supply cavity.

[0027] Furthermore, dehumidifiers include:

[0028] A water storage tank is located at the bottom of the shell, with its top connected to the cooling air duct. It is used to collect the condensate that is cooled in the airflow within the cooling air duct.

[0029] The dehumidifier of this invention, having a refrigeration unit, each refrigeration unit has two refrigeration sides located on either side of the air inlet and arranged opposite each other to provide cooling capacity. These two opposing refrigeration sides directly construct a cooling air duct connecting to the air inlet. Compared to existing technologies, the dehumidifier of this invention does not require a large air duct to house the dehumidification components. Under the action of the fan mechanism, the airflow completely flows through the cooling air duct and is cooled by the cooling capacity provided by the refrigeration sides, producing condensate to remove water from the airflow and achieve dehumidification. Compared to existing technologies where the effective airflow is cooled through the dehumidification components (cooling air duct), the effective airflow is significantly increased. Therefore, this invention allows for a smaller dehumidifier while maintaining dehumidification capacity and performance, improving the user experience.

[0030] Furthermore, in the dehumidifier of the present invention, since it has multiple air inlets and a cooling section, and thus multiple cooling air ducts arranged side by side, the contact area between the airflow flowing through the cooling air ducts and the cooling side is further increased when the total air inlet area of ​​the air inlets and cooling air ducts is constant. Therefore, the dehumidification performance of the dehumidifier of the present invention can be further improved.

[0048] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the dehumidifier includes a housing 100, multiple refrigeration units 200, and a fan mechanism 300. The housing 100 is provided with an air outlet 110 and multiple air inlets 120 arranged side-by-side. The multiple refrigeration units 200 are arranged side-by-side within the housing 100 corresponding to the multiple air inlets 120. Each refrigeration unit 200 includes two opposing refrigeration sides 210, located on either side of the air inlet 120, and the refrigeration sides 210 are used to provide cooling capacity. A cooling air duct 220 is provided between the two opposing refrigeration sides 210, connecting the air outlet 110 and the corresponding air inlet 120. The fan mechanism 300 is used to draw airflow from outside the housing 100 through the multiple air inlets 120 into the cooling air duct 220 and then discharge it from the housing 100 through the air outlet 110.

[0049] Because the dehumidifier of this embodiment has a refrigeration unit 200, each refrigeration unit 200 has two refrigeration side surfaces 210 located on both sides of the air inlet 120 and arranged opposite each other for providing cooling capacity. These two oppositely arranged refrigeration side surfaces 210 directly construct a cooling air duct 220 connecting to the air inlet 120. Compared to the prior art, the dehumidifier of this invention does not require a large air duct to house the dehumidification components. Furthermore, under the action of the fan mechanism 300, the airflow completely flows through the cooling air duct 220 and is cooled by the cooling capacity provided by the refrigeration side surfaces 210, producing condensate to remove water from the airflow and achieve the dehumidification process. Compared to the prior art, the effective airflow cooled by the dehumidification components (cooling air duct 220) is greatly increased. Therefore, this embodiment allows the dehumidifier to have a smaller size while ensuring the dehumidification capacity and performance, thus improving the user experience.

[0050] Furthermore, since the dehumidifier of this embodiment has multiple air inlets 120 and cooling units 200, and multiple cooling air ducts 220 arranged side by side, the contact area between the airflow through the cooling air ducts 220 and the cooling side 210 is further increased when the total air intake area of ​​the air inlets 120 and the cooling air ducts 220 is constant. 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 this embodiment, the dehumidifier also includes multiple heating units 400, which are arranged side by side inside the housing 100. Each heating unit 400 includes two oppositely arranged heating sides 410, which are used to provide heat. A heating air duct 420 is provided 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. In addition, the fan mechanism 300 is also used to guide the airflow that flows into the cooling air duct 220 to flow through the heating air duct 420 and then be discharged from the housing 100 through the air outlet 110.

[0052] Understandably, if the airflow, after being cooled by the cooling duct 220, were directly discharged from the casing 100 into the indoor space, it would lower the ambient temperature of the indoor space. Therefore, through the configuration of the cooling unit 200 and the heating duct 420, under the action of the fan mechanism 300, the cooled airflow will also flow through the heating duct 420 and be heated before finally flowing into the indoor space. This effectively prevents the dehumidified airflow from affecting the ambient temperature of the indoor space after it is discharged into the indoor space, thus ensuring the comfort level of the indoor ambient temperature.

[0053] Reference Figure 3 and Figure 5 In this embodiment, the fan mechanism 300 is also used to draw airflow outside the housing 100 into the heating air duct 420 through the air inlet 120, and guide the airflow through the cooling air duct 220 and then discharge it out of the housing 100 through multiple air inlets 120.

[0054] Understandably, when a dehumidifier is operating continuously, frost may form on the cooling section 200, affecting the cooling effect of the cooling side 210 on the airflow and significantly reducing the dehumidifier's dehumidification performance. Therefore, in this embodiment, the fan mechanism 300 can also cause the airflow outside the housing 100 to be drawn into the heating duct 420 through the air outlet 110 and heated, then flow through the cooling duct 220 to defrost the two opposing cooling sides 210 of the cooling section 200, and finally be discharged from the housing 100 through multiple air inlets 120, thus achieving the defrosting process and ensuring the normal dehumidification function and performance of the dehumidifier.

[0055] In addition, the heating unit 400 may not need to operate during the defrosting function of the dehumidifier.

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

[0057] It is understandable that by alternating the arrangement of multiple heating units 400 and multiple cooling units 200, and by alternately arranging the heating duct 420 and cooling duct 220 side-by-side, the heating units 400 (heating duct 420) and cooling units 200 (cooling duct 220) can be highly integrated. This ingenious and reasonable design can further reduce the space occupied by the cooling units 200 and heating units 400. Therefore, this embodiment can further allow the dehumidifier to have a smaller size, improving 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 housing 100, and multiple air inlets 120 are arranged in the left-right direction on the front side of the housing 100, and each air inlet 120 extends in the up-down direction. The housing 100 is provided with a connecting air cavity 130 that connects the heating air duct 420 and the cooling air duct 220. 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 is understood that by setting the connecting air cavity 130 and its position, the airflow can flow through the entire cooling air duct 220 before entering the heating air duct 420, thereby ensuring the cooling effect of the cooling unit 200 on the airflow flowing through the cooling air duct 220, avoiding the waste of cooling capacity, and ensuring the dehumidification performance of the dehumidifier.

[0060] Reference Figure 4 or Figure 5 In this embodiment, the rear wall and 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-shaped wall 160.

[0061] It is understandable that by setting the arc-shaped wall 160, the airflow can be well guided when the dehumidifier in the following embodiment is running the dehumidification and defrosting functions, effectively avoiding the loss of airflow during the flow process and ensuring the dehumidification performance of the dehumidifier.

[0062] In some modified embodiments, the dehumidifier includes a condenser and an evaporator. The condenser's condenser fins are arranged side-by-side in the left-right direction within the housing 100, and each condenser fin is arranged vertically. A heating section 400 is formed between two adjacent condenser fins, and two opposing heating sides 410 are the opposite sides of two adjacent condenser fins. Similarly, the evaporator's evaporator fins are arranged side-by-side in the left-right direction within the housing 100, and each evaporator fin is arranged vertically. A cooling section 200 is formed between two adjacent evaporator fins, and two opposing heating sides 410 are the opposite sides of two adjacent evaporator fins. This allows for the construction of the cooling section 200, cooling side 210, heating section 400, and heating side 410 in the above embodiments, achieving the beneficial technical effects described in some of the above embodiments.

[0063] Furthermore, in order to make the dehumidifier smaller in size, the condenser fins and evaporator fins can be arranged alternately in pairs, thereby highly integrating the heating section 400 (heating air duct 420) and the cooling section 200 (cooling air duct 220) together, achieving the beneficial technical effects of the above embodiments.

[0064] In some other variations, the difference from the variations described above is that the condenser can be replaced with an electrically heated structure including heating fins. The beneficial technical effects described in this embodiment can be achieved similarly.

[0065] Reference Figure 2 and Figure 3 In this embodiment, the dehumidifier includes multiple semiconductor cooling chips 500, which are stacked side by side in the left-right direction within the housing 100. Each semiconductor cooling chip 500 is arranged in the up-down direction. The cooling side 210 is the cooling end face of the semiconductor cooling chip 500, and the heating side 410 is the heat dissipation end face of the semiconductor cooling chip 500.

[0066] It is understood that by arranging multiple semiconductor cooling chips 500 with alternating cooling end faces and heat dissipation end faces, the cooling section 200, cooling side 210, heating section 400, and heating side 410 in the above embodiments can be constructed to achieve the beneficial technical effects described in the above embodiments.

[0067] Meanwhile, this embodiment fully utilizes the heat dissipation end of the thermoelectric cooler 500, eliminating the need for a separate additional heating mechanism (such as the condenser in the aforementioned modified embodiment), thus saving the energy consumed by the additional heating mechanism and ensuring the energy efficiency of the dehumidifier. It also further reduces the width of the integrated heating unit 400 (heating air duct 420) and cooling unit 200 (cooling air duct 220), allowing for a smaller dehumidifier size and improved user experience. Furthermore, compared to heat exchange components such as condensers and evaporators, the thermoelectric cooler 500 itself does not require heat-conducting copper pipes or other structures passing through the fins, allowing for a smaller space occupied by the thermoelectric cooler 500, further enabling a smaller dehumidifier size and improved user experience. It should also be noted that the smaller size of the dehumidifier means that, compared to existing structures, more thermoelectric coolers 500 can be installed within the same device volume, effectively ensuring the dehumidification performance and improving the user experience.

[0068] Furthermore, compared to the aforementioned modified embodiments or prior art, this embodiment utilizes a semiconductor refrigeration chip 500 to construct the cooling section 200, cooling side 210, heating section 400, and heating side 410, without setting up components such as heat-conducting fins, thereby reducing heat loss between the semiconductor refrigeration chip 500 and the fins. The airflow in the cooling duct 220 and heating duct 420 can directly contact the cooling end face or heat dissipation end face of the semiconductor refrigeration chip 500, 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 can be the leftmost and rightmost two of a plurality of semiconductor cooling chips 500 arranged in the left-right direction.

[0070] Furthermore, the number of semiconductor cooling chips 500 can be 59. This number of semiconductor cooling chips 500 can well meet the dehumidification performance requirements of dehumidifier users in the home field. Moreover, this number of semiconductor cooling chips 500 can form 29 cooling air ducts 220 and 29 heating air ducts 420. Thus, the left and right end faces of the housing 100 can be the cooling end face and the heat dissipation end face of the semiconductor cooling chip 500, respectively.

[0071] Reference Figure 2 and Figure 3In this embodiment, the semiconductor cooling chip 500 can have a length L of 150 mm, a width M of 150 mm, and a thickness K of 4 mm. This size of semiconductor cooling chip 500 can well meet the size and dehumidification performance requirements of dehumidifier users in the home field. The distance H between any two semiconductor cooling chips 500 can be 1.25 mm to effectively ensure the cooling and heating effects of the airflow passing through the cooling air duct 220 and the heating air duct 420.

[0072] In this embodiment, the dehumidifier includes a temperature sensor, which is disposed on the thermoelectric cooler 500 to monitor the temperature of the thermoelectric cooler 500. When the temperature of the thermoelectric cooler 500 is within the set temperature range for frosting, the dehumidifier starts to operate 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 on its front side, and a plurality of air inlets 120 are located on the front panel 140; the dehumidifier also includes a first air duct baffle 610 and a second air duct baffle 620. The first air duct baffle 610 is disposed inside the housing 100 and covers the underside of a plurality of semiconductor cooling chips 500. A heat-through hole 61 communicating with the second connecting cavity 132 is opened on the first air duct baffle 61 at a position corresponding to the heating air duct 420. 1; The second air duct baffle 620 is disposed inside the housing 100. The second air duct baffle 620 covers the top of multiple semiconductor cooling chips 500, and the second air duct baffle 620 has an air outlet 621 connected to the air outlet 110 at the 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 panels 210; the heating air duct 420 is located between the front panel 140 and the two heating side panels 410.

[0074] It is understandable that the construction of the aforementioned cooling air duct 220 and heating air duct 420 is achieved through the arrangement of the front side plate, the first air duct baffle 610, and the second air duct baffle 620. This includes the connection between the cooling air duct 220 and the first connecting cavity 131 in the above embodiment, the connection between the heating air duct 420, the first connecting cavity 131, the second connecting cavity 132, and the air supply cavity 150 in the following embodiment, and the requirement in the above embodiment that the air first enters the cooling air duct 220 through the air inlet 120; simultaneously... During the dehumidification process, the airflow follows the flow path of air inlet 120, cooling air duct 220, first connecting cavity 131 (and second connecting cavity 132), heating air duct 420, and air outlet 110 in sequence to ensure the normal operation of the dehumidification function. Alternatively, the airflow follows the flow path of air outlet 110, heating air duct 420, (second connecting cavity 132), first connecting cavity 131, and air inlet 120 in sequence to ensure the normal operation of the defrosting function.

[0075] In a modified embodiment, the difference from the above embodiment is that the dehumidifier further includes a third air duct baffle, which is disposed inside the housing 100, is disposed opposite to the front panel 140, and is located behind the plurality of semiconductor cooling chips 500. A cooling hole is provided on the third air duct baffle corresponding to the position of the cooling air duct 220, which connects to the first connecting cavity 131; the heating air duct 420 is located between the third air duct baffle, the front panel 140, and the two heating sides 410.

[0076] Understandably, by setting up the third air duct baffle, the connection between the heating air duct 420 and the first connecting cavity 131 is blocked. Therefore, during the dehumidification process, the airflow will flow sequentially through the air inlet 120, cooling air duct 220, first connecting cavity 131, second connecting cavity 132, heating air duct 420, and air outlet 110, ensuring the normal operation of the dehumidifier's dehumidification function. Alternatively, the airflow can flow sequentially through the air outlet 110, heating air duct 420, second connecting cavity 132, first connecting cavity 131, cooling air duct 220, and air inlet 120, ensuring the dehumidifier's defrosting function. Normal operation; at the same time, the setting of the third air duct baffle can effectively avoid the interference between the airflow from the cooling air duct 220 through the first connecting cavity 131 to the heating air duct 420 and the airflow from the cooling air duct 220 through the first connecting cavity 131 and the second connecting cavity 132 to the heating air duct 420 during the dehumidification function operation, as well as the interference between the airflow from the heating air duct 420 through the first connecting cavity 131 to the cooling air duct 220 and the airflow from the heating air duct 420 through the second connecting cavity 132 and the first connecting cavity 131 to the cooling air duct 220 during the defrosting function operation.

[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 chips 500, and the limiting protrusions 630 are used to maintain the distance between the semiconductor cooling chips 500.

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

[0079] It is understood that in this embodiment, the housing 100 directly forms the air duct structure of the fan mechanism 300. With this structure, the dehumidifier can switch the airflow direction in the dehumidification and defrosting functions by switching the forward and reverse rotation of the fan mechanism 300. Alternatively, the fan mechanism 300 can be independent of the housing 100, by connecting the fan inlet 120 of the fan mechanism 300 to the outlet 110, or by connecting the fan outlet 110 of the fan mechanism 300 to the inlet 120. Similarly, the dehumidifier can switch the airflow direction in the dehumidification and defrosting functions by switching the forward and reverse rotation of the fan mechanism 300. The dehumidifier can also be equipped with components such as a flipping mechanism to drive the fan inlet 120 and the fan outlet 110 to interchange and connect, thereby achieving the switching of the airflow direction in the dehumidification and defrosting functions.

[0080] Furthermore, during the dehumidification process, the fan mechanism 300 can rotate at 1400 rpm to ensure the dehumidification effect of the dehumidifier.

[0081] In addition, the fan mechanism 300 can be set to three speed levels: high, medium, and low. The high speed can be 1680 rpm, the medium speed can be 1400 rpm, and the low speed can be 610 rpm, so that the dehumidifier can provide different air volumes, enabling the dehumidifier to have more operating conditions and effectively meet the user's usage scenarios and the needs of various 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. The top of the water storage tank 700 is connected to the cooling air duct 220. The water storage tank 700 is used to collect the condensate cooled in the airflow within the cooling air duct 220. Therefore, the dehumidifier of this embodiment can prevent condensate from leaking into the indoor space during operation, ensuring a better user experience.

[0083] In addition, the top of the water storage tank 700 can be connected to the cooling air duct 220 by connecting the air cavity 130. During the dehumidification process, the condensate in the cooling air duct 220 or the water after the frost in the cooling air duct 220 melts during the defrosting process can flow along the cooling air duct 220 through the connecting air cavity 130 and enter the water storage tank 700.

[0084] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
