Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidification equipment, in particular to a dehumidifier. Background Art

[0002] The fresh air processing path of the existing dehumidifier cannot be changed at will after design and production, that is, the fresh air to be dehumidified must pass through the fresh air inlet, filter, first-level surface cooler, first-level rotor and first-level fan in sequence before the low-humidity gas can be transported to the environment to be dehumidified.

[0003] However, the moisture content and temperature of outdoor fresh air are constantly changing, especially in winter, when the temperature and humidity of the fresh air are extremely low, even exceeding the cooling and dehumidification capabilities of the surface cooler. At this time, the surface cooler not only fails to achieve the cooling and dehumidification effects, but also causes a pressure drop of 100 to 300 Pa to the fresh air. As a result, the fan needs to increase energy consumption when supplying air to offset the pressure drop caused by the surface cooler. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to provide a dehumidifier capable of adjusting the fresh air path according to the temperature and humidity of the fresh air.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The air path adjustment assembly includes at least two surface coolers whose working surfaces are parallel to the fresh air flow direction;

[0008] The surface cooler is hinged with a first damper and a second damper;

[0014] Along the fresh air flow direction, the first electric rotating shaft and the second electric rotating shaft are respectively arranged on both sides of the surface cooler;

[0015] The first electric rotating shaft or the second electric rotating shaft on the adjacent surface coolers are arranged opposite to each other;

[0016] The first electric rotating shaft is arranged at one end of the surface cooler close to the filter;

[0017] The second electric rotating shaft is arranged at one end of the surface cooler close to the dehumidification rotating wheel;

[0042] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0043] The most critical concept of the utility model is that the surface cooler, the first air door and the second air door can divide the shell into two independent parts. At this time, the fresh air can flow through the surface cooler and complete the preliminary cooling and dehumidification work; when the temperature and humidity meter detects that the temperature and humidity values ​​of the fresh air are lower than the set values, the first air door and the second air door are opened, so that the fresh air can be directly dehumidified by the subsequent equipment that can deeply dehumidify, thereby achieving energy-saving effects.

[0044] Please refer to Figures 1 to 3 The dehumidifier provided by the utility model comprises a housing 1, and a temperature and humidity meter 2 and an air path adjustment component 3 which are sequentially arranged in the housing 1 along the flow direction of fresh air;

[0045] The air path regulating assembly 3 includes at least two surface coolers 31 whose working surfaces are parallel to the fresh air flow direction;

[0046] The surface cooler 31 is hinged with a first damper 311 and a second damper 312;

[0047] When the cooler 31 is working, the cooler 31 , the first damper 311 and the second damper 312 separate the housing 1 into two parts.

[0048] From the above description, it can be seen that the beneficial effects of the utility model are: providing a dehumidifier, when working normally, the shell 1 can be separated into two independent parts by the surface cooler 31, the first air door 311 and the second air door 312, at this time, the fresh air can flow through the surface cooler 31, and complete the preliminary cooling and dehumidification work; when the thermometer and humidity meter 2 detects that the temperature and humidity values ​​of the fresh air are lower than the set values, the first air door 311 and the second air door 312 are opened, so that the fresh air is directly dehumidified by the subsequent equipment that can perform deep dehumidification; compared with the existing dehumidifier, it can detect the temperature and humidity values ​​of the gas to be dehumidified in real time, and automatically determine whether it is necessary to use the surface cooler 31 for preliminary dehumidification work, so that when the gas parameters cannot meet the dehumidification conditions of the surface cooler 31, the dehumidification path can be changed, thereby achieving the effect of energy saving and emission reduction.

[0049] Further, the number of the surface coolers 31 may be three;

[0050] The surface cooler 31 is stacked in the housing 1 in a direction perpendicular to the flow of fresh air;

[0051] When the surface cooler 31 is working, the two ends of the surface cooler 31 in the middle are sealed and connected to the surface coolers 31 on both sides through the first air door 311 or the second air door 312 respectively;

[0052] The surface cooler 31 located on the outside is sealedly connected to the housing 1 through the first damper 311 or the second damper 312 .

[0053] It can be seen from the above description that in order to improve the condensation and dehumidification efficiency of the dehumidifier, this connection method can provide a certain design idea by setting multiple surface coolers 31 inside the dehumidifier according to actual needs, and the number of surface coolers is not limited to two or three. When more surface coolers need to be set, multiple surface coolers can be combined according to the above connection method.

[0054] Furthermore, a filter 4 and a dehumidification wheel 5 are sequentially arranged inside the housing 1 along the fresh air flow direction;

[0055] The temperature and humidity meter 2 is arranged at the air inlet end of the filter 4;

[0056] The air passage adjustment component 3 is arranged between the filter 4 and the dehumidification wheel 5 .

[0057] From the above description, it can be seen that the design has made specific modifications to the overall structure of the dehumidifier. The filter 4 filters out dust impurities mixed in the fresh air, which can protect the relevant components inside the dehumidifier and increase the overall service life; the dehumidification wheel 5 can perform deep dehumidification on the fresh air after preliminary dehumidification or when the humidity is lower than that which the surface cooler 31 can handle, thereby ensuring that the air quality in the environment meets the requirements of daily work.

[0058] Furthermore, the air duct adjustment assembly 3 further includes a first electric rotating shaft 313 and a second electric rotating shaft 314;

[0059] Along the fresh air flow direction, the first electric rotating shaft 313 and the second electric rotating shaft 314 are respectively arranged on both sides of the surface cooler 31;

[0060] The first electric rotating shafts 313 on the adjacent surface coolers 31 are arranged opposite to each other;

[0061] The second electric rotating shafts 314 on the adjacent surface coolers 31 are arranged opposite to each other;

[0062] The first electric rotating shaft 313 is disposed at one end of the surface cooler 31 close to the filter 4;

[0063] The second electric rotating shaft 314 is disposed at one end of the surface cooler 31 close to the dehumidification wheel 5;

[0064] The first air door 311 is hinged to the surface cooler 31 through a first electric rotating shaft 313;

[0065] The second air door 312 is hinged to the surface cooler 31 through a second electric rotating shaft 314 .

[0066] Furthermore, the housing 1 is provided with a first stopper 11 and a second stopper 12;

[0067] The first limiting member 11 or the second limiting member 12 is disposed between the surface coolers 31;

[0068] The first stopper 11 is arranged on the turning path of the first damper 311;

[0069] The second limiting member 12 is arranged on the turning path of the second damper 312;

[0070] When the first damper 311 conflicts with the first stopper 11 , and the second damper 312 conflicts with the second stopper 12 , the cooler 31 , the first damper 311 , and the second damper 312 separate the housing 1 into two parts.

[0071] Specifically, sealing components are provided on the contact surface between the first damper 311 and the first limit member 11, and on the contact surface between the second damper 312 and the second limit member 12, so as to prevent the undehumidified gas from flowing directly into the dehumidification wheel 5 through the gap, thereby increasing the working energy consumption of the dehumidification wheel 5. The sealing component can be any commercially available device with a sealing effect, such as a sealing strip or a sealing ring.

[0072] From the above description, it can be seen that the design further optimizes the structure of the air duct regulating component 3, and provides structural support for how the air duct regulating component 3 separates the shell 1 into two parts when the surface cooler 31 is working; by setting the first limit member 11 and the second limit member 12, it can be avoided that the first damper 311 and the second damper 312 are prevented from over-flipping and affecting the effect of the air duct regulating component 3 to separate the shell 1, so that the undehumidified fresh air directly enters the dehumidification wheel 5, thereby increasing the working energy consumption of the dehumidification wheel 5.

[0073] Furthermore, a fresh air valve 6 and a fan 7 are sequentially arranged inside the housing 1 along the fresh air flow direction;

[0074] The temperature and humidity meter 2 is arranged between the fresh air valve 6 and the filter 4;

[0075] The fan 7 is arranged at the air outlet end of the dehumidification wheel 5 .

[0076] From the above description, it can be seen that the fresh air valve 6 can be used to control the flow rate of fresh air, so that the user can adjust the dehumidification amount of the dehumidifier according to the actual dehumidification needs; the fan 7 is the power source of the dehumidifier, and the fan 7 can continuously introduce the humid gas in the environment to be dehumidified into the dehumidifier for dehumidification, thereby ensuring the continuity and stability of the dehumidification work.

[0077] Furthermore, the above-mentioned dehumidifier also includes a controller;

[0078] The fresh air valve 6, the temperature and humidity meter 2, the first electric rotating shaft 313, the second electric rotating shaft 314, the dehumidification wheel 5 and the fan 7 are all electrically connected to the controller.

[0079] From the above description, it can be seen that the controller not only enables users to select or set the appropriate dehumidification mode according to personal needs to meet personalized operations; the controller also enables the various components inside the dehumidifier to perform dehumidification work in an orderly manner, avoiding the dehumidifier from failing to operate normally due to improper operation.

[0080] The dehumidifier of the utility model can be used for daily dehumidification work.

[0081] Please refer to Figures 1 to 3 , Embodiment 1 of the present utility model is:

[0082] A dehumidifier comprises a controller, a shell 1, and a fresh air valve 6, a temperature and humidity meter 2, a filter 4, an air path adjustment component 3, a dehumidification wheel 5 and a fan 7 which are sequentially arranged in the shell 1 along the fresh air flow direction; the air path adjustment component 3 comprises a surface cooler 31 whose two working surfaces are parallel to the fresh air flow direction; a first damper 311 and a second damper 312 are hinged on the surface cooler 31 through a first electric rotating shaft 313 and a second electric rotating shaft 314; that is, the temperature and humidity meter 2 is arranged between the fresh air valve 6 and the filter 4; the air path adjustment component 3 is arranged between the filter 4 and the dehumidification wheel 5; the fan 7 is arranged at the air outlet end of the dehumidification wheel 5; the fresh air valve 6, the temperature and humidity meter 2, the first electric rotating shaft 313, the second electric rotating shaft 314, the dehumidification wheel 5 and the fan 7 are all electrically connected to the controller.

[0083] Along the flow direction of fresh air, the first electric shaft 313 and the second electric shaft 314 are respectively arranged on both sides of the cooler 31; the first electric shaft 313 or the second electric shaft 314 on adjacent coolers 31 are arranged relatively to each other; the first electric shaft 313 is arranged at one end of the cooler 31 close to the filter 4; the second electric shaft 314 is arranged at one end of the cooler 31 close to the dehumidification wheel 5; the first air door 311 is hinged to the cooler 31 through the first electric shaft 313; the second air door 312 is hinged to the cooler 31 through the second electric shaft 314.

[0084] A first limit member 11 and a second limit member 12 are provided on the shell 1; the first limit member 11 or the second limit member 12 is arranged between the surface cooler 31; the first limit member 11 is arranged on the flipping path of the first damper 311; the second limit member 12 is arranged on the flipping path of the second damper 312; when the first damper 311 conflicts with the first limit member 11, and the second damper 312 conflicts with the second limit member 12, the surface cooler 31, the first damper 311 and the second damper 312 separate the shell 1 into two parts.

[0085] The working principle of the utility model is:

[0086] Surface cooler 31 mode: the hot and humid fresh air in the external environment enters the dehumidifier through the fresh air valve 6 under the action of the fan 7, and flows to the air path adjustment component 3 after being filtered by the filter 4; at this time, the first damper 311 and the second damper 312 respectively abut against the first limit member 11 and the second limit member 12, so that the shell 1 is separated into two independent parts; after the fresh air is initially cooled and dehumidified by the surface cooler 31, it flows to the dehumidification wheel 5 for deep dehumidification; finally, it is discharged into the environment to be dehumidified under the negative pressure of the fan 7.

[0087] Direct-through mode: When the thermometer detects that the temperature and humidity of the fresh air are lower than the working conditions of the surface cooler 31, the corresponding start signal is sent to the first electric shaft 313 and the second electric shaft 314 through control, so that the inside of the dehumidifier is completely connected, that is, the fresh air can flow directly to the dehumidification wheel 5 for deep dehumidification. Since the fresh air does not pass through the surface cooler 31, the fan 7 can introduce the dehumidified fresh air into the dehumidified environment at a low power state, thereby achieving the effect of energy saving and emission reduction.

[0088] To sum up, the dehumidifier provided by the utility model can divide the shell into two independent parts through the surface cooler, the first air door and the second air door when working normally. At this time, the fresh air can flow through the surface cooler and complete the preliminary cooling and dehumidification work; when the thermometer and humidity meter detects that the temperature and humidity values ​​of the fresh air are lower than the set values, the first air door and the second air door are opened, so that the fresh air can be directly dehumidified by the subsequent equipment that can deeply dehumidify; compared with the existing dehumidifier, it can detect the temperature and humidity values ​​of the gas to be dehumidified in real time, and automatically determine whether it is necessary to use a surface cooler for preliminary dehumidification work, so that the dehumidification path can be changed when the gas parameters cannot meet the dehumidification conditions of the surface cooler. Since the fresh air does not pass through the surface cooler, the fan can introduce the dehumidified fresh air into the environment to be dehumidified in a low-power state, thereby achieving the effect of energy saving and emission reduction.
