Description

Technical Field

[0001] This utility model belongs to the technical field of dehumidifier control unit, specifically relating to a dehumidifier logic control unit. Background Technology

[0002] A dehumidifier is a device that reduces air humidity by cooling. It typically consists of a compressor, heat exchanger, fan, water tank, casing, and control system. The working principle is that the fan draws humid air into the machine, and the heat exchanger condenses the water molecules in the air into water droplets, thereby reducing the absolute humidity in the air, improving environmental comfort, and preventing mold growth.

[0003] The control system is the core component that controls the operation of the dehumidifier, and the dehumidifier logic control unit is also the core part of the control system. The dehumidifier logic control unit is mainly used to control the operating status of the dehumidifier.

[0004] In the existing technology, most dehumidifier logic control units have relatively simple control logic, lack shutdown time settings, and cannot control the shutdown time. As a result, they cannot control the internal heat dissipation of the dehumidifier, which can easily cause damage to the dehumidifier. At the same time, they lack high temperature protection functions and cannot protect the dehumidifier from high temperature shutdown, making the dehumidifier logic control unit less safe and reliable to use.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a dehumidifier logic control unit.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figures 1 to 3 As shown, a dehumidifier logic control unit in one embodiment of the present invention includes: a main control chip.

[0027] like Figures 2 to 3 As shown, the main control chip consists of a PCB board 1, multiple wire terminals 2, several capacitors 3 and a common-mode inductor filter 4. The multiple wire terminals 2 are fixedly mounted on both sides of the PCB board 1, the capacitors 3 are fixedly mounted on the top of the PCB board 1, and the common-mode inductor filter 4 is fixedly mounted on the top of the PCB board 1.

[0028] Specifically, the outer side of the PCB board 1 has multiple mounting bolt holes. By providing mounting bolt holes, it is easy to use screws to mount the PCB board 1 into the dehumidifier.

[0029] like Figure 1 As shown, the main control chip has an external DC-DC module connected to its power interface, and an AC-DC module is connected to one side of the DC-DC module. The AC-DC module is connected to an external 220V AC power supply.

[0030] like Figure 1 As shown, the digital signal interface of the main control chip is connected to a temperature detection unit, a manual gear detection unit, and an automatic gear detection unit.

[0031] like Figure 1 As shown, the temperature detection unit, manual gear detection unit, and automatic gear detection unit are all connected to a half-wave rectifier module.

[0032] like Figure 1 As shown, the temperature detection unit is used to detect the internal temperature of the dehumidifier. The temperature detection unit works with the half-wave rectifier module to generate a temperature signal. The high-temperature protection status of the dehumidifier is determined by detecting the temperature of the motor inside the dehumidifier through the temperature detection unit.

[0033] like Figure 1 As shown, the manual mode detection unit is used to detect the manual mode signal of the dehumidifier. The manual mode detection unit works with the half-wave rectifier module to generate a manual switch signal. This generated manual switch signal controls the manual dehumidification mode of the dehumidifier.

[0034] like Figure 1 As shown, the automatic gear detection unit is used to detect the automatic gear signal of the dehumidifier. The automatic gear detection unit works with the half-wave rectifier module to generate an automatic switching signal. This generated automatic switching signal controls the automatic dehumidification mode of the dehumidifier.

[0035] like Figure 1 As shown, the digital signal interface of the main control chip is also connected to the fan control unit, motor control unit, heater control unit, and temperature controller control unit. Each of the fan control unit, motor control unit, heater control unit, and temperature controller control unit is connected to a relay.

[0036] like Figure 1 As shown, the fan control unit is connected to a relay contact, and the other relay contact is connected to a fan interface. The entry of outside air and the heat dissipation of the motor inside the dehumidifier are controlled by controlling the fan's operation.

[0037] like Figure 1 As shown, the motor control unit is connected to the relay contacts, and the other contact of the relay is connected to the motor interface. The dehumidification status of the dehumidifier is controlled by controlling the operation of the motor.

[0038] like Figure 1 As shown, the heater control unit is connected to the relay contacts, and the other contact of the relay is connected to the heater interface. The temperature controller control unit is connected to the relay contacts, and the other contact of the relay is connected to the temperature controller interface.

[0039] In practical use, when the dehumidifier needs to run in manual dehumidification mode, the main control chip detects the manual switch signal and transmits the fan control signal, heater control signal, and motor control signal to the fan interface, heater interface, and motor interface in the dehumidifier through the interface circuit of the main control chip. By controlling the operation of the fan, heater, and motor, the dehumidifier is controlled to perform manual dehumidification.

[0040] When the dehumidifier needs to operate in automatic dehumidification mode, the main control chip detects the automatic switch signal and transmits the fan control signal, heater control signal, and motor control signal to the fan interface, heater interface, and motor interface in the dehumidifier through the interface circuit of the main control chip. By controlling the operation of the fan, heater, and motor, the dehumidifier is controlled to perform automatic dehumidification.

[0041] When the main control chip receives a stop switch signal, it immediately cuts off the heater control signal, and the dehumidifier's heater stops heating. In order to ensure sufficient heat dissipation of the dehumidifier, the main control chip cuts off the fan control signal and motor control signal after the fan and motor have been running for a period of time, thereby controlling the operation of the fan and motor.

[0042] Meanwhile, during the use of the dehumidifier, the internal temperature of the dehumidifier can be detected by the temperature detection unit. When the internal temperature of the dehumidifier is higher than 85℃, the main control chip controls the dehumidifier to automatically stop working, thereby protecting the dehumidifier from high temperature shutdown.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
