Abstract
Description
Technical Field
[0001] The utility model relates to the field of dehumidifiers, in particular to industrial dehumidifiers. Background Art
[0002] Patent document CN 116147085 A discloses a dust-proof industrial dehumidifier. The dehumidifier has an air duct within the body, with both ends leading to the outside of the body and connecting to the outside world. A heat exchanger, fan, and filter cloth are installed within the duct along the airflow direction. The fan draws outside air into the duct, where it moves to the filter cloth for filtration, then to the heat exchanger for dehumidification, before being discharged outside. While the filter cloth can filter dust from the air, it accumulates over time, requiring regular manual cleaning. However, the filter cloth can sometimes become covered with dust before the cleaning deadline. Excessive dust accumulation not only results in poor filtering effectiveness but also blocks the air duct, resulting in poor dehumidification. Utility Model Content
[0003] The utility model aims to provide an industrial dehumidifier, which can respond when the air duct is blocked, avoiding continuing dehumidification in this state, thereby avoiding poor dehumidification effect.
[0004] In order to solve the above problems, the technical solution of the utility model is:
[0005] An embodiment of the present utility model provides an industrial dehumidifier, in which an air duct is opened inside the body, and both ends of the air duct lead to the outside of the body to form an air inlet and an air outlet respectively. A dehumidification component and a fan are provided in the air duct. The air outside the body is driven by the fan to enter the air duct through the air inlet, is dehumidified by the dehumidification component and then discharged through the air outlet. The dehumidifier also includes a pressure difference switch and a response component.
[0006] The pressure differential switch is provided with a first probe and a second probe. The first probe is located in the air duct and detects wind pressure. The second probe is located outside the air duct and detects atmospheric pressure. The response element is connected to the pressure differential switch, and the response element can make a preset response according to the detection result of the pressure differential switch.
[0007] Furthermore, the response component includes an alarm, which is connected to the pressure difference switch signal. When the pressure difference between the first probe and the second probe is greater than a preset value, the pressure difference switch triggers the alarm.
[0008] Furthermore, the air inlet and / or the air outlet are provided on the side wall of the industrial dehumidifier body.
[0009] Furthermore, the air outlet is specifically provided on the front side wall of the industrial dehumidifier body, and / or the air inlet is specifically provided on the back side wall of the industrial dehumidifier body.
[0010] Furthermore, a filter is installed in the air duct.
[0011] Furthermore, the dehumidification component includes an evaporator and a condenser, and the evaporator and the condenser are arranged in sequence in the air duct according to the air flow direction.
[0012] Furthermore, the fan is located between the condenser and the air outlet.
[0013] Furthermore, the dehumidification component also includes an expansion valve, a filter and a compressor, the compressor is connected to the condenser, the condenser is connected to the expansion valve, the expansion valve is connected to the filter, the filter is connected to the evaporator, and the evaporator is connected to the compressor.
[0014] Furthermore, a partition is provided in the machine body, which divides the inner cavity of the machine body into an air duct and an installation cavity. The differential pressure switch is installed in the installation cavity, and the first probe passes through the partition and enters the air duct.
[0015] Furthermore, the second probe is specifically arranged in the installation cavity.
[0016] The beneficial effects of the technical solutions provided in the embodiments of the present application include at least:
[0017] Under normal circumstances, the differential pressure switch detects a pressure difference between the air duct and the ambient atmospheric pressure that is less than the set value. Once the pressure difference exceeds the set value, the differential pressure switch sends a signal to the response element, which then responds with a pre-set response. This prevents the dehumidifier from continuing to dehumidify when the air duct is blocked, thus preventing poor dehumidification performance.
[0018] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1
[0029] An embodiment of the present utility model provides an industrial dehumidifier, in which an air duct 6 is opened inside the body, and both ends of the air duct 6 lead to the outside of the body to form an air inlet 1 and an air outlet 5 respectively. A dehumidification component and a fan 4 are provided in the air duct 6. Air 10 outside the body is driven by the fan 4 to enter the air duct 6 through the air inlet 1, is dehumidified by the dehumidification component and then discharged through the air outlet 5. The dehumidifier also includes a pressure difference switch 8 and a response component.
[0030] The differential pressure switch 8 is provided with a first probe 9 and a second probe 16. The first probe 9 is located in the air duct 6 and is used to detect wind pressure. The second probe 16 is located outside the air duct and is used to detect atmospheric pressure. The response member is connected to the differential pressure switch 8, and the response member can make a preset response according to the detection result of the differential pressure switch 8 to prevent the industrial dehumidifier from continuing to dehumidify when the air duct is blocked, thereby avoiding poor dehumidification effect.
[0031] It should be understood that the industrial dehumidifier of this embodiment is used to dehumidify the air, and an inner cavity is provided in the body of the dehumidifier. Figure 3 As shown, the industrial dehumidifier of the present invention is provided with a partition 11 to separate the inner cavity of the body into an air duct 6 and an installation cavity 7. The air duct 6 is for the air outside the body to enter and leave the industrial dehumidifier, and the installation cavity 7 is used to install some components of the industrial dehumidifier. Figure 1 As shown, the front end of the air duct 6 extends outside the body, forming an air outlet 5 on the front side wall of the body. The rear end of the air duct 6 extends outside the body, forming an air inlet 1 on the back side wall of the body. The air inlet 1 is equipped with a filter 15. The evaporator 2, condenser 3 and fan 4 are arranged in the air duct 6 in the direction of air flow 10.
[0032] According to the industrial dehumidifier provided by the embodiment of the present invention, the dehumidification component also includes an expansion valve 13, a filter and a compressor 12. The compressor 12 is connected to the condenser 3, the condenser 3 is connected to the expansion valve 13, the expansion valve 13 is connected to the filter, the filter is connected to the evaporator, and the evaporator 2 is connected to the compressor 12.
[0033] Specifically, mounting cavity 7 houses an expansion valve 13, a filter (not shown), and a compressor 12. Compressor 12 is connected to condenser 3, which is connected to expansion valve 13, which is connected to filter 13, which is connected to evaporator 2, which is connected to compressor 12. This creates a refrigerant cycle, serving as a dehumidification component. Air 10, driven by fan 4, enters air duct 6 through air inlet 1, where it is dehumidified by evaporator 2 and condenser 3 before being discharged through air outlet 5.
[0034] It should be noted that the mounting cavity 7 is provided with a pressure differential switch 8 and an alarm 17 which are electrically connected to each other. Figure 2 and Figure 4 As shown, the first probe 9 of the differential pressure switch 8 passes through the partition 11 and enters the air duct 6, and the second probe 16 is located in the installation cavity 7. The second probe 16 detects atmospheric pressure, and the first probe 9 detects the wind pressure generated by the flow of air 10. If the filter 15 is seriously accumulated with dust and becomes blocked, there will be a difference in air pressure between the air duct 6 and the installation cavity 7. When the difference reaches a preset level, the difference between the first probe 9 and the second probe 16 will be greater than the preset value. At this time, the differential pressure switch 8 triggers the alarm 17, which acts as a response component and issues an alarm to notify the staff to clean the filter 15.
[0035] After the filter screen 15 is cleaned, on the one hand, a better filtering effect is restored, and on the other hand, the air duct 6 can be unblocked, and the dehumidification effect of this industrial dehumidifier will be restored to a better state. In addition, after the air duct 6 is unblocked, the pressure difference detected by the pressure difference switch 8 will also be restored to be less than the preset value.
[0036] Four lifting legs 14 are mounted on the outer wall of the industrial dehumidifier of the embodiment of the present invention.
[0037] Example 2
[0038] The second embodiment is essentially the same as the first embodiment, except that the alarm 17 in the first embodiment is replaced with a start / stop switch, which controls the start / stop of the entire industrial dehumidifier. If the pressure difference exceeds a preset value, the start / stop switch, acting as a response element, shuts down the industrial dehumidifier and waits for staff to clean the filter 15.
[0039] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
