[0002] Dehumidifier is a kind of air dehumidification equipment that is widely used in the market. It is mainly composed of compressor, evaporator, condenser, throttling element and fan.

[0003] During use, existing dehumidifiers sequentially pass air through the evaporator and condenser to achieve dehumidification. However, the air temperature rises after passing through the condenser, causing the temperature inside the room to rise.

[0083] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments 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 making creative efforts should fall within the scope of protection of the present invention.

[0084] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0085] According to an embodiment of the present invention, an embodiment of a cold air type dehumidifier is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0086] The embodiment of the present invention provides a cold air dehumidifier, such as Figure 1 As shown, it includes a casing, an evaporator 100 , a condenser 200 , a throttling element and a compressor 300 . The cold air type dehumidifier also includes a first valve mechanism 10 , a second valve mechanism 20 , a first fan 30 and a second fan 40 .

[0087] The compressor 300 is connected to the evaporator 100 and the condenser 200 respectively, and the evaporator 100 and the condenser 200 are connected via the throttling element.

[0088] The housing is provided with a first air inlet 11, a first air outlet 12, a second air inlet 21, and a second air outlet 22. A first air duct is formed within the housing between the first air inlet 11 and the second air outlet 22. A second valve mechanism 20 is provided on the first air duct, which divides the first air duct into a first air duct A and a first air duct B. The first air duct A is connected to the second air outlet 22, and the first air duct B is connected to the first air inlet 11. The evaporator 100 is provided on the first air duct B, and the condenser 200 and the first fan 30 are provided on the first air duct A. When the second valve mechanism 20 is opened, the first air duct A and the first air duct B are connected. When the second valve mechanism 20 is closed, the first air duct A and the first air duct B are disconnected.

[0089] A third air duct 211 is further formed in the casing between the first air duct A and the second air inlet 21 , and a first valve mechanism A is provided at the connection between the third air duct 211 and the first air duct A for controlling the connection or disconnection between the third air duct 211 and the first air duct A.

[0090] A second air duct 101 is formed between the first air duct B and the first air outlet 12. A first valve mechanism B is provided at the connection between the second air duct 101 and the first air duct B, which is used to control the connection or disconnection between the second air duct 101 and the first air duct B; the second fan 40 is arranged on the second air duct 101.

[0091] The cold air type dehumidifier is provided with a cooling mode and a dehumidification mode. When the cold air type dehumidifier is in the cooling mode, the second valve mechanism 20 is closed, the first valve mechanisms A and B are opened, the first air duct B is connected to the second air duct 101, and the first air duct A is connected to the third air duct 211. The wind entering the first air duct B from the first air inlet 11 passes through the evaporator 100 and is discharged from the first air outlet 12 by the second fan 40. The wind entering the first air duct A from the second air inlet 21 passes through the condenser 200 and is discharged from the second air outlet 22 by the first fan 30.

[0092] When the cold air type dehumidifier is in the dehumidification mode, the second valve mechanism 20 is opened, the first valve mechanisms A and B are closed, the first air duct B is connected to the first air duct A, and the air entering the first air duct B from the first air inlet 11 passes through the evaporator 100 and the condenser 200 in sequence and is discharged from the second air outlet 22 by the first fan 30.

[0093] The present embodiment does not limit the specific structures of the first valve mechanism 10 and the second valve mechanism 20. It is sufficient that the first valve mechanism A can cut off or connect the first air duct A and the third air duct 211, and the first valve mechanism B can cut off or connect the first air duct B and the second air duct 101. Similarly, the second valve mechanism 20 can cut off or connect the first air duct A and the second air duct B.

[0094] It should be noted that the first valve mechanisms A and B can be two parts of the first valve mechanism 10, or they can be two independent first valve mechanisms 10. That is, for the sake of ease of description in this embodiment, the first valve mechanisms are named first valve mechanism A and first valve mechanism B, respectively. In one embodiment, the first valve mechanism includes a left blade and a right blade, and also includes a motor for controlling the rotation of the left blade and the right blade. The left blade is equivalent to the first valve mechanism A, and the right blade is equivalent to the second valve mechanism B. In another embodiment, there are two first valve mechanisms, one named first valve mechanism A and the other named first valve mechanism B. The structures of the first valve mechanism A and the first valve mechanism B can be the same or different, and the two are independently controlled and operated.

[0095] Through the above content, the cold air type dehumidifier is provided with a first valve mechanism 10 and a second valve mechanism 20 that can be opened and closed, so that during the use of the cold air type dehumidifier, the direction of the airflow can be changed by controlling the opening and closing states of the first valve mechanism 10 and the second valve mechanism 20, so that the evaporator 100 and the condenser 200 can be in a relatively independent space. After the evaporator 100 lowers the temperature of the airflow, it is not easily interfered with by the condenser 200, thereby realizing the refrigeration function of the dehumidifier and improving the functionality of the dehumidifier.

[0096] Optionally, the first valve mechanism 10 includes a first transmission shaft and a first folding plate. In one embodiment, one end of the first transmission shaft is connected to an external motor, and the other end is connected to the first folding plate to drive the first folding plate to expand or fold. When the first folding plate is extended to its limit position, the first valve mechanism is closed; when the first folding plate is folded, the first valve mechanism is open.

[0097] When the first valve mechanisms A and B are opened, the first transmission shaft drives the first folding plate to fold by using the drive of an external motor, the first air duct B is connected to the second air duct, and the first air duct A is connected to the third air duct; when the first valve mechanisms A and B are closed, the first transmission shaft drives the first folding plate to unfold by using the drive of an external motor, the first air duct B is disconnected from the second air duct, and the first air duct A is disconnected from the third air duct.

[0098] The second valve mechanism 20 includes a second transmission shaft and a second folding plate. One end of the second transmission shaft is connected to an external motor, and the other end is connected to the second folding plate to drive the second folding plate to expand or fold. When the second folding plate is fully expanded, the second valve mechanism is closed. When the second folding plate is folded, the second valve mechanism is open.

[0099] When the second valve mechanism 20 is opened, the second transmission shaft drives the second folding plate to fold by driving an external motor, and the first air duct A is connected to the first air duct B; when the second valve mechanism is closed, the second transmission shaft drives the second folding plate to unfold by driving an external motor, and the first air duct A is disconnected from the first air duct B.

[0100] Furthermore, it should be noted that the first transmission shaft and the second transmission shaft may be connected to the same external motor or to different external motors, which is not specifically limited in this embodiment. Furthermore, in other embodiments, the first valve mechanism and the second valve mechanism may be provided with internal motors for driving the first transmission shaft and / or the second transmission shaft.

[0101] As described above, both the first valve mechanism 10 and the second valve mechanism 20 use folding plates to control the opening and closing of the air duct. The folding plates have a simple structure and are easy to control, thereby increasing the flexibility of the first valve mechanism 10 and the second valve mechanism 20, simplifying the first valve mechanism 10 and the second valve mechanism 20, and helping to reduce costs.

[0102] Optionally, the first valve mechanism A includes a third transmission shaft, a rotating plate A, and a first drive motor; and the first valve mechanism B includes a fourth transmission shaft, a rotating plate B, and a second drive motor. One end of the third transmission shaft is connected to the rotating plate A, and the other end is connected to the first drive motor.

[0103] When the first valve mechanism A is opened, the first drive motor drives the third transmission shaft to rotate to a first target position, and the first air duct A is connected to the third air duct; when the first valve mechanism A is closed, the first drive motor drives the third transmission shaft to rotate to a second target position, and the first air duct A is disconnected from the third air duct.

[0104] One end of the fourth transmission shaft is connected to the rotating plate B, and the other end is connected to the second drive motor. When the first valve mechanism B is open, the second drive motor drives the fourth transmission shaft to rotate to a third target position, thereby connecting the first air duct B with the second air duct. When the first valve mechanism B is closed, the second drive motor drives the fourth transmission shaft to rotate to a fourth target position, thereby disconnecting the first air duct B from the second air duct.

[0105] The second valve mechanism 20 includes a fifth transmission shaft, a flap, and a third drive motor. One end of the fifth transmission shaft is connected to the flap, and the other end is connected to the third drive motor.

[0106] When the second valve mechanism 20 is opened, the third drive motor drives the fifth transmission shaft to rotate to the fifth target position, and the first air duct A is connected to the first air duct B; when the second valve mechanism is closed, the third drive motor drives the fifth transmission shaft to rotate to the sixth target position, and the first air duct A is disconnected from the first air duct B.

[0107] Similarly, the first drive motor, the second drive motor, and the third drive motor can all be replaced by external motors. That is, in other embodiments, no motors are required in the first valve mechanisms A, B, and the second valve mechanism.

[0108] Through the above content, the first valve mechanism 10 and the second valve mechanism 20 adopt a rotating plate or a flip plate structure, which has a longer life and is not easy to be damaged compared to the folding plate. It is beneficial to reduce the maintenance workload of the cold air type dehumidifier, making it less likely to frequently replace the valve mechanism of the cold air type dehumidifier, saving usage costs.

[0109] Furthermore, it should be noted that in the above-described embodiment, the first valve mechanism 10 and the second valve mechanism 20 both employ the same or similar structures. However, this embodiment is not limited to this. In other words, in some embodiments, the first valve mechanism 10 and the second valve mechanism 20 may employ significantly different structures. For example, the first valve mechanism 10 may employ a folded plate structure, while the second valve mechanism 20 may employ a flap structure; or the first valve mechanism 10 may employ a flap structure, while the second valve mechanism 20 may employ a folded plate structure. Furthermore, the first valve mechanisms A and B may employ different structures.

[0110] The embodiment of the present invention also provides a control method for a cold air dehumidifier, which can be applied in Figure 2The illustrated application environment specifically includes a terminal 001 and a server 002. Terminal 001 and server 002 communicate via a network. In one embodiment, terminal 001 is configured to obtain a mode instruction and transmit the mode instruction to server 002. Server 002 generates a control instruction based on the mode instruction for controlling the internal mechanism of the cold air dehumidifier and transmits the control instruction to the corresponding terminal 001. After receiving the control instruction, terminal 001 controls the internal mechanism of the cold air dehumidifier according to the control instruction, causing the cold air dehumidifier to perform dehumidification or cooling.

[0111] In another embodiment, after the server 002 generates the control instruction, it directly controls the internal mechanism of the cold air type dehumidifier to make the cold air type dehumidifier dehumidify or cool; in other embodiments, after receiving the mode instruction, the terminal 001 generates a control instruction according to the mode instruction, controls the internal mechanism of the cold air type dehumidifier to make the cold air type dehumidifier dehumidify or cool, and then uploads the data to be backed up to the server 002, and the server 002 stores the data.

[0112] That is, the cold air dehumidifier control method in this embodiment can be implemented using terminal 001 or server 002, and this embodiment does not specifically limit this. Specifically, terminal 001 can be, but is not limited to, various smart phones, personal computers, laptops, tablet computers, smart control panels, portable wearable devices, or other devices capable of network connection. Server 002 can be implemented as a standalone server or a server cluster consisting of multiple servers, and this embodiment does not specifically limit this.

[0113] In addition, in one embodiment, one server 002 may be connected to only one terminal 001 , and this embodiment does not specifically limit the number of terminals 001 and servers 002 .

[0114] Next, the control method for the cold air dehumidifier provided by this embodiment will be described by taking the application to electronic equipment as an example. Figure 1 Terminal 001 in . Figure 3 As shown, the method includes the following steps:

[0115] Step S101, obtaining a mode instruction.

[0116] In one embodiment, a mode instruction is used to control a cold air dehumidifier to enter a corresponding mode. For example, in one application scenario, if the mode instruction is a dehumidification instruction, it is used to control the cold air dehumidifier to enter dehumidification mode; in another application scenario, if the mode instruction is a standby instruction, it is used to control the cold air dehumidifier to enter standby mode. That is, this embodiment does not specifically limit the specific structure, content, and mode type of the mode instruction; the purpose is to be able to control the cold air dehumidifier to enter the corresponding mode through the mode instruction. The modes of a cold air dehumidifier may include dehumidification mode, cooling mode, standby mode, power saving mode, etc.

[0117] In one embodiment, a mode command is generated by a user operating an interactive device and transmitted to the electronic device. The interactive device may be a remote control, a keyboard, a touch screen, etc., which is not specifically limited in this embodiment. For ease of understanding, for example, in one application scenario, a user triggers the dehumidification button on a remote control. The remote control generates a dehumidification command and transmits the dehumidification command to the electronic device, so that the electronic device receives the mode command, which is the dehumidification command.

[0118] In another embodiment, the mode instruction is generated by the electronic device. For example, in one application scenario, the electronic device generates a mode instruction of a specified type after monitoring the current time to reach a set time. At this time, the electronic device determines that the mode instruction has been obtained.

[0119] This embodiment does not specifically limit the method for generating and transmitting the mode instruction and the method for the electronic device to obtain the mode instruction.

[0120] Step S102, when the mode instruction is a dehumidification instruction, the first valve mechanisms A and B are controlled to be closed, the second valve mechanism is controlled to be open, and the first air inlet is connected to the second air outlet to form a first air duct.

[0121] In one embodiment, the mode instruction includes a dehumidification instruction. The electronic device determines whether the mode instruction is a dehumidification instruction through model comparison or identifier recognition. For ease of understanding, for example, in one application scenario, a model of a dehumidification instruction is stored in the electronic device. After the electronic device obtains the mode instruction, it compares the mode instruction with the dehumidification instruction model. If the two are the same, the electronic device determines that the obtained mode instruction is a dehumidification instruction. In another application scenario, after the electronic device obtains the mode instruction, it reads the identifier contained in the mode instruction. If the identifier is the same as the preset dehumidification identifier, the electronic device determines that the obtained mode instruction is a dehumidification instruction. This embodiment does not specifically limit this.

[0122] In one embodiment, by changing the opening and closing state of the first valve mechanism and / or changing the opening and closing state of the second valve mechanism, the air inlet position and the air outlet position of the cold air type dehumidifier can be changed, that is, the flow path of the air flow inside the cold air type dehumidifier is changed. For the sake of convenience of description, the flow path of the air flow inside the cold air type dehumidifier is called an air duct.

[0123] Among them, when the first air inlet is connected to the second air outlet, the path of the air flow from the first air inlet to the second air outlet is called the first air duct. Figure 1 As shown, the electronic device controls the second valve mechanism 20 to open, so that the first air inlet 11 is connected to the second air outlet 22; the electronic device controls the first valve mechanisms A and B to close, so that the first air inlet 11 is not connected to other air outlets and other air inlets, so that a first air duct is formed inside the cold air dehumidifier.

[0124] Step S103: Entering a dehumidification control mode to perform dehumidification according to preset dehumidification parameters.

[0125] The dehumidification parameters refer to parameters that need to be set when the cold air dehumidifier is in the dehumidification mode, such as motor speed, dehumidification time, etc., which are not specifically limited in this embodiment.

[0126] The dehumidification control mode refers to the control phase before entering the dehumidification mode, or the control phase of the entire dehumidification process. For ease of understanding, for example, in one application scenario, after the electronic device completes control of the first valve mechanism 10 and the second valve mechanism 20, it also needs to control the evaporator 100, condenser 200, compressor 300, and fan in the cold air dehumidifier. The process of controlling such devices is the dehumidification control mode.

[0127] After the electronic device enters the dehumidification control mode, the device in the cold air dehumidifier is controlled according to the dehumidification parameters, so that the cold air dehumidifier dehumidifies the space in which it is located.

[0128] Step S104, when the mode instruction is a cooling instruction, the first valve mechanism A and B are controlled to open, the second valve mechanism is closed, the first air inlet is connected to the first air outlet, a second air duct is formed between the first air outlet and the first air duct B, the second air inlet is connected to the second air outlet, and a third air duct is formed between the second air inlet and the first air duct A; the wind entering the first air duct B from the first air inlet is discharged from the first air outlet by the second fan through the evaporator, and the wind entering the first air duct A from the second air inlet is discharged from the second air outlet by the first fan through the condenser.

[0129] In one embodiment, the mode instruction also includes a cooling instruction. Specifically, the electronic device can determine whether the mode instruction is a cooling instruction by model comparison or identification recognition, which is the same as the principle of determining the dehumidification instruction and will not be repeated here.

[0130] In one embodiment, if Figure 1 As shown, the electronic device opens the first valve mechanisms A and B to connect the first air inlet 11 with the first air outlet 12, and at the same time connects the second air inlet 21 with the second air outlet 22; the electronic device closes the second valve mechanism 20 to isolate the first air inlet 11 from the second air outlet 22, and at the same time isolates the first air outlet 12 from the second air inlet 21, so that the evaporator 100 and the condenser 200 are relatively independent.

[0131] Step S105: Entering a cooling control mode to perform cooling according to preset cooling parameters.

[0132] The cooling parameters refer to the parameters that need to be set when the cold air dehumidifier is in cooling mode, such as motor speed, dehumidification time, etc., which are not specifically limited in this embodiment.

[0133] Cooling control mode refers to the control phase before entering cooling mode, or the control phase of the entire cooling process. For ease of understanding, for example, in one application scenario, the electronic device enters cooling control mode after completing control of the first and second valve mechanisms. Based on the cooling parameters, the electronic device controls the evaporator, condenser, compressor, and fan within the cold air dehumidifier, enabling the cold air dehumidifier to cool the space in which it is located.

[0134] Through the above steps, the electronic device controls the opening and closing of the first and second valve mechanisms to modify the airflow path within the cold-air dehumidifier, forming a first air duct suitable for dehumidification and a second and third air ducts suitable for cooling. Because the evaporator and condenser are located in separate spaces during the cooling process, the cooling effect of the cold-air dehumidifier is maintained, easily meeting the user's dehumidification and cooling needs, and increasing the dehumidifier's functionality.

[0135] Optionally, controlling the first valve mechanisms A and B to be closed, the second valve mechanism to be open, and the first air inlet to be connected to the second air outlet to form a first air duct includes:

[0136] Step S201 , controlling the first valve mechanisms A and B to close the third air duct and the second air duct respectively.

[0137] The first valve mechanism A is located in the third air duct and is used to open or close the third air duct. When the electronic device controls the first valve mechanism A to close, the first valve mechanism A closes the third air duct, so that the third air duct is not connected to the first air inlet, the first air outlet, and the second air outlet.

[0138] Similarly, in one embodiment, the first valve mechanism B is located within the second air duct and is configured to open or close the second air duct. When the electronic device controls the first valve mechanism B to close, the first valve mechanism B closes the second air duct, disconnecting the second air duct from the first air inlet, the second air inlet, and the second air outlet.

[0139] Step S202: Control the second valve mechanism to open, so that the first air inlet is connected to the second air outlet to form the first air duct.

[0140] The second valve mechanism is located between the evaporator and condenser. When the electronic device controls the second valve mechanism to open, the first air inlet is connected to the second air outlet. It should be noted that since the closure of the first valve mechanism closes both the third and second air ducts, air entering the first air inlet can only flow out of the second air outlet.

[0141] Through the above steps, the first valve mechanisms A and B can close the third and second air ducts, making the first air outlet and the second air inlet relatively independent and unable to communicate with other air inlets or outlets. The second valve mechanism then opens, connecting the first air inlet and the second air outlet, ensuring that airflow in the first air duct passes through the evaporator and condenser sequentially, reducing the humidity of the airflow and ensuring the dehumidification effect of the cold air dehumidifier.

[0142] Optionally, the controlling of the first valve mechanisms A and B to open, the second valve mechanism to close, the first air inlet to communicate with the first air outlet, a second air duct to be formed between the first air outlet and the first air duct B, the second air inlet to communicate with the second air outlet, and a third air duct to be formed between the second air inlet and the first air duct A, comprises:

[0143] Step S203: Control the second valve mechanism to close, so that the first air duct A and the first air duct B are disconnected.

[0144] Among them, after the electronic device closes the second valve mechanism, the first air duct is divided into two parts, namely the first air duct A and the first air duct B, and the evaporator and the condenser are located in the first air duct A and the first air duct B respectively.

[0145] Step S204 , controlling the first valve mechanisms A and B to open, the first air outlet is connected to the first air duct B to form a second air duct, and the second air inlet is connected to the first air duct A to form a third air duct.

[0146] After the electronic device controls the first valve mechanism A to open, affected by the closing of the second valve mechanism, a new ventilation duct, namely the second duct, is formed between the first air outlet and the first air duct B; through, a new ventilation duct, namely the third duct, is formed between the second air inlet and the first air duct A.

[0147] Through the above steps, since the second valve mechanism is located between the evaporator and condenser, the evaporator and condenser can be separated when the second valve mechanism is closed. At the same time, the first valve mechanisms A and B are opened, connecting the first air outlet and the first air inlet. This allows the air in the first channel to be cooled after being processed by the evaporator, thereby achieving a cooling effect.

[0148] Optionally, controlling the first valve mechanisms A and B to close and the second valve mechanism to open includes:

[0149] Step S301 : Control the drivers in the first valve mechanisms A and B to start, drive the first isolation plate to a preset first closed position, and drive the second isolation plate to a preset second closed position.

[0150] In one embodiment, the first valve mechanism includes a driver, a first isolation plate, and a second isolation plate. In one application scenario, the first isolation plate corresponds to the third air duct, and the second isolation plate corresponds to the second air duct. In another application scenario, the first isolation plate corresponds to the second air duct, and the second isolation plate corresponds to the third air duct. This embodiment is not specifically limited to this.

[0151] The electronic device controls the driver of the first valve mechanism to drive the first and second isolation plates. Specifically, the first and second isolation plates can be driven to rotate or translate following the driver, which is not specifically limited in this embodiment.

[0152] The first closed position refers to a position where the first isolation plate can close the corresponding air duct. Similarly, the second closed position refers to a position where the second isolation plate can close the corresponding air duct.

[0153] Step S302: Control the driver in the second valve mechanism to start, and drive the third isolation plate to a preset third open position.

[0154] In one embodiment, the second valve mechanism includes a driver and a third isolation plate. In one application scenario, the electronic device drives the third isolation plate to rotate by controlling the driver. When the third isolation plate rotates to the third open position, the first air inlet is connected to the second air outlet, and the air flow can pass through the evaporator and condenser in sequence from the first air inlet to the second air outlet. In another application scenario, the electronic device drives the third isolation plate to move horizontally by controlling the driver to rise and fall. When the third isolation plate moves to the third open position, the first air inlet is connected to the second air outlet. This embodiment does not specifically limit the driving method of the third isolation plate, nor does it specifically limit the type of driver. It is intended to be able to drive the third isolation plate to the third open position.

[0155] Through the above steps, the first valve mechanism and the second valve mechanism adopt a combination of a driver and an isolation plate, which facilitates accurate and quick control of the first isolation structure and the second valve mechanism, and helps to ensure the cooling efficiency and cooling effect of the cold air dehumidifier.

[0156] Optionally, controlling the first valve mechanisms A and B to open and the second valve mechanism to close includes:

[0157] Step S303: Control the driver in the first valve mechanism to start, drive the first isolation plate to a preset first open position, and drive the second isolation plate to a preset second open position.

[0158] The first open position refers to the position where the first isolation plate opens the corresponding air duct; the second open position refers to the position where the second isolation plate opens the corresponding air duct. The corresponding air duct can be the third air duct or the second air duct, which is not specifically limited in this embodiment.

[0159] Step S304: Control the driver in the second valve mechanism to start, and drive the third isolation plate to a preset third closed position.

[0160] Among them, the electronic device controls the driver in the second valve mechanism to drive the third isolation plate to move. When the third isolation plate reaches the third closed position, the driver in the second valve mechanism stops driving, so that the second isolation plate separates the evaporator and the condenser in two air ducts.

[0161] It should be noted that the first open position, second open position, third open position, first closed position, second closed position, and third closed position can be detected by sensors, such as infrared sensors, radar sensors, and laser sensors, or can be calculated using driver parameters, which is not specifically limited in this embodiment. For ease of understanding, for example, the rotation angle of the first, second, or third isolation plate can be calculated based on the driver's rotational speed and driving time. For another example, if the driver is a stepper motor, the rotation angle can be calculated based on the number of rotations of the stepper motor.

[0162] Through the above steps, the first valve mechanism and the second valve mechanism adopt a combination of a driver and an isolation plate, which facilitates accurate and quick control of the first isolation structure and the second valve mechanism, and helps to ensure the cooling efficiency and cooling effect of the cold air dehumidifier.

[0163] Optionally, the first isolation plate, the second isolation plate and the third isolation plate are all grid-type sealing plates.

[0164] In one embodiment, the grid-type sealing plate includes a grid plate and a bottom plate fixedly connected to the grid plate, so that the first isolation plate, the second isolation plate and the third isolation plate can seal corresponding channels.

[0165] In another embodiment, the grille-type sealing plate includes a frame having a plurality of mutually parallel longitudinal plates fixedly connected thereto, and transverse plates rotatably disposed between adjacent longitudinal plates. When the transverse plates are rotated to a horizontal position, the grille-type sealing plate is in a closed state, and when the transverse plates are rotated to a vertical position, the grille-type sealing plate is in an open state.

[0166] This embodiment does not limit the specific structure of the grid-type sealing plate.

[0167] Through the above steps, the use of a grid-type structure helps to reduce the weight of the first isolation plate, the second isolation plate and the third isolation plate, and improve the strength of the first isolation plate, the second isolation plate and the third isolation plate.

[0168] Alternatively, as Figure 4 As shown, the dehumidification parameters include a first dehumidification time threshold, a second dehumidification time threshold and a first rotation speed threshold.

[0169] The step of entering a dehumidification control mode to perform dehumidification according to preset dehumidification parameters includes:

[0170] Step S501: After the first dehumidification time threshold has passed, start the first fan and control the first fan to reach the first speed threshold.

[0171] The electronic device starts timing after completing the previous control action. When the timing time is equal to the first dehumidification time threshold, the first fan is started and the speed of the first fan is controlled at the same time.

[0172] Step S502: After the second dehumidification time threshold has passed, start the compressor.

[0173] When the speed of the first fan reaches a first speed threshold, the electronic device starts timing. When the timing time is equal to a second dehumidification time threshold, the electronic device transmits a start instruction to the compressor to start the compressor and realize the dehumidification cycle.

[0174] Through the above steps, the electronic device controls the first fan and the compressor according to the dehumidification parameters, so that the cold air dehumidifier enters the dehumidification mode and dehumidifies the air in the space, which helps to ensure the dehumidification effect of the cold air dehumidifier.

[0175] Alternatively, as Figure 4 As shown, the cooling parameters include a first cooling time threshold, a second cooling time threshold, a second rotation speed threshold and a third rotation speed threshold.

[0176] Entering the refrigeration control mode for refrigeration according to the preset refrigeration parameters includes:

[0177] Step S601: After the first cooling time threshold has passed, the first fan is started and controlled to reach the second speed threshold, and the second fan is started and controlled to reach the third speed threshold.

[0178] After completing the previous action, the electronic device starts timing. When the timing reaches a first cooling time threshold, the electronic device starts the first fan and controls the speed of the first fan to reach a second speed threshold; and starts the second fan and controls the speed of the second fan to reach a third speed threshold.

[0179] It should be noted that the first dehumidification time threshold, the second dehumidification time threshold, the first speed threshold, the first cooling time threshold, the second cooling time threshold, the second speed threshold and the third speed threshold are all determined according to actual conditions or actual usage environment, and this embodiment does not make specific limitations.

[0180] Step S602: After the second cooling time threshold has passed, start the compressor.

[0181] When the first fan reaches the second speed threshold and the second fan reaches the third speed threshold, the electronic device starts timing. After the timing time is equal to the second cooling time threshold, the electronic device controls the compressor to start.

[0182] Through the above steps, the electronic device controls the first fan, the second fan and the compressor according to the cooling parameters, so that the cold air dehumidifier enters the cooling mode and cools the air in the space, which helps to ensure the cooling effect of the cold air dehumidifier.

[0183] Optionally, after the acquisition mode instruction, the method further includes:

[0184] Step S701: determine whether the mode instruction matches the current control mode.

[0185] Since the mode command is used to control the cold air dehumidifier to enter a corresponding mode, the mode command can represent a mode of the cold air dehumidifier. For example, when the mode command is a dehumidification command, the mode command can represent that the cold air dehumidifier needs to enter the dehumidification mode; when the mode command is a cooling command, the mode command can represent that the cold air dehumidifier needs to enter the cooling mode.

[0186] Based on this, after obtaining the mode instruction, the electronic device matches the mode instruction with the current control mode. The current control mode refers to the mode that the cold air type dehumidifier is currently in, such as dehumidification mode or cooling mode. In one embodiment, if the mode instruction is used to represent the dehumidification mode, and the current control mode of the cold air type dehumidifier is also the dehumidification mode, the electronic device determines that it matches; otherwise, the electronic device determines that it does not match. Similarly, if the mode instruction is used to represent the cooling mode, and the current control mode of the cold air type dehumidifier is the cooling mode, the two match, otherwise they do not match. That is, when the mode represented by the mode instruction is the same as the current control mode, the electronic device determines that the mode instruction matches the current control mode; if they are not the same, the electronic device determines that the mode instruction does not match the current control mode.

[0187] If the mode instruction does not match the current control mode, steps 702-704 are executed.

[0188] Specifically, the mode instruction does not match the current control mode, which means that the mode of the cold air dehumidifier needs to be switched, for example, the dehumidification mode is switched to the cooling mode or the cooling mode is switched to the dehumidification mode. Figure 5 shown.

[0189] Step S702: Turn off the compressor.

[0190] The electronics first switch off the compressor in preparation for switching modes.

[0191] Step S703 , when the mode instruction is a dehumidification instruction, the first fan and the second fan are turned off, and then the first valve mechanism is controlled to be closed and the second valve mechanism is controlled to be open, thereby entering the dehumidification control mode.

[0192] Specifically, in one embodiment, the electronic device controls the compressor to shut down and begins timing. After the timing reaches a preset first switching duration t1, the electronic device controls the first and second fans to shut down and begins timing. After the timing reaches a preset second switching duration t2, the electronic device controls the first valve mechanisms A and B to close, the second valve mechanism to open, and timing begins again. After the timing reaches a third switching duration t3, the electronic device enters the dehumidification control mode.

[0193] When switching to dehumidification mode, the electronic device first turns off the first and second fans to reduce airflow. The electronic device then controls the first valve mechanisms A and B to close and the second valve mechanism to open, finally entering dehumidification control mode and performing the dehumidification function.

[0194] Step S704 , when the mode instruction is a cooling instruction, the first fan is turned off, and then the first valve mechanism is controlled to open and the second valve mechanism is controlled to close, thereby entering the cooling control mode.

[0195] Specifically, in one embodiment, the electronic device controls the compressor to shut down and begins timing. After the timing reaches a preset fourth switching duration t4, the electronic device turns off the first fan and begins timing. After the timing reaches a preset fifth switching duration t5, the electronic device controls the first valve mechanisms A and B to open, the second valve mechanism to close, and timing begins again. After the timing reaches a preset sixth switching duration t6, the electronic device enters the cooling control mode.

[0196] Through the above steps, the cold air type dehumidifier can switch modes when in operation, thereby meeting the user's usage needs and improving the mode switching functionality of the cold air type dehumidifier.

[0197] In summary, by controlling the first and second valve mechanisms, the air inlet and outlet of the cold air dehumidifier are changed, creating different air ducts within the dehumidifier. When dehumidification is required, the first valve mechanisms A and B are closed, and the second valve mechanism is opened, forming the first air duct. Air entering the cold air dehumidifier passes through the evaporator and condenser in the first air duct, achieving dehumidification. When cooling is required, the first valve mechanisms A and B are opened, and the second valve mechanism is closed. Air entering the first air duct B cools down after passing through the evaporator, and then enters the room through the second air duct, cooling the room. This allows the cold air dehumidifier to have both dehumidification and cooling functions, providing diverse functionality and superior performance.

[0198] The present application also provides a cold air dehumidifier control device. Figure 6 As shown, it includes an acquisition module 1 for acquiring a mode instruction;

[0200] Dehumidification control module 3, used to enter the dehumidification control mode for dehumidification according to preset dehumidification parameters;

[0201] Refrigeration module 4, configured to, when the mode instruction is a cooling instruction, control the first valve mechanisms A and B to open, the second valve mechanism to close, the first air inlet to communicate with the first air outlet, a second air duct to be formed between the first air outlet and the first air duct B, the second air inlet to communicate with the second air outlet, a third air duct to be formed between the second air inlet and the first air duct A; air entering the first air duct B through the first air inlet is discharged from the first air outlet by the second fan through the evaporator, and air entering the first air duct A through the second air inlet is discharged from the second air outlet by the first fan through the condenser;

[0202] The refrigeration control module 5 is used to enter the refrigeration control mode for refrigeration according to preset refrigeration parameters.

[0203] Optionally, the dehumidification module 2 includes a first dehumidification control unit, configured to control the first valve mechanisms A and B to close the third air duct and the second air duct respectively;

[0204] a second dehumidification control unit, configured to control the second valve mechanism to open, so that the first air inlet communicates with the second air outlet to form the first air duct;

[0205] The refrigeration module 4 includes a first refrigeration control unit for controlling the second valve mechanism to close so as to disconnect the first air duct A from the first air duct B;

[0206] The second refrigeration control unit is used to control the opening of the first valve mechanisms A and B, the first air outlet is connected to the first air duct B to form a second air duct, and the second air inlet is connected to the first air duct A to form a third air duct.

[0207] Optionally, the dehumidification parameters include a first dehumidification time threshold, a second dehumidification time threshold and a first rotation speed threshold;

[0208] The dehumidification control module 3 includes a fan control unit, which is used to start the first fan and control the first fan to reach the first speed threshold after the first dehumidification time threshold has passed;

[0209] The compressor control unit is configured to start the compressor after the second dehumidification time threshold has passed.

[0210] Optionally, the cooling parameters include a first cooling time threshold, a second cooling time threshold, a second rotation speed threshold, and a third rotation speed threshold;

[0211] The refrigeration control module 5 includes a fan processing unit, which is used to start the first fan and control the first fan to reach the second speed threshold after the first refrigeration time threshold has passed, and to start the second fan and control the second fan to reach the third speed threshold;

[0212] The compressor processing unit is configured to start the compressor after the second cooling time threshold has passed.

[0213] Optionally, the device further comprises a judgment module, configured to judge whether the mode instruction matches the current control mode;

[0214] Mode switching module, used to shut down the compressor if it does not match.

[0215] And, when the mode instruction is a dehumidification instruction, turning off the first fan and the second fan, and then controlling the first valve mechanism to close and the second valve mechanism to open, thereby entering the dehumidification control mode;

[0216] When the mode instruction is a cooling instruction, the first fan is turned off, and then the first valve mechanism is controlled to open and the second valve mechanism is controlled to close, thereby entering the cooling control mode.

[0217] Through the above structure, after the acquisition module 1 obtains the mode instruction, it can control the air-cooled dehumidifier to enter different control modes according to the type of mode instruction. Among them, when the mode instruction is a dehumidification instruction, the dehumidification module 2 changes the opening and closing states of the first valve mechanism and the second valve mechanism, so that a first air duct is formed inside the cold air dehumidifier, and then the dehumidification control module 3 causes the air-cooled dehumidifier to dehumidify according to the dehumidification parameters. When the mode instruction is a cooling instruction, the cooling module 4 changes the opening and closing states of the first valve mechanism and the second valve mechanism, so that the first air duct is divided into the first air duct A and the first air duct B, wherein the first air duct A is connected to the third air duct, and the first air duct B is connected to the second air duct, and then the cooling control module causes the air-cooled dehumidifier to cool according to the cooling parameters. By controlling the air-cooled dehumidifier, the air-cooled dehumidifier can both dehumidify and cool, and has multiple functions, thereby improving the functionality of the air-cooled dehumidifier.
