Problems solved by technology

Its working principle is: the humid air is sucked into the machine by the fan, and passes through the heat exchanger. At this time, the water molecules in the air are condensed into water droplets, and the dry air after treatment is discharged from the machine through the air outlet. This cycle keeps the indoor humidity. At a suitable relative humidity, if the air outlet is covered by clothes or towels during the dehumidifier process, and the hot air from the air outlet cannot be blown out, the internal temperature of the dehumidifier will rise, which may cause the shell of the dehumidifier to deform. Or aging, it is easy to cause the life of the dehumidifier to be affected, so it needs to be improved

Embodiment 1

[0021] like figure 1 , figure 2 As shown, a dehumidifier outlet cover detection device provided in this embodiment includes a controller 1, a first temperature sensor 2 installed at the dehumidifier outlet, and a second temperature sensor 2 installed on the dehumidifier for monitoring the ambient temperature. The sensor 3 is provided with a wind pressure sensor 4 for detecting wind pressure at the fan outlet of the dehumidifier, and the controller 1 is connected with the first temperature sensor 2, the wind pressure sensor 4 and the second temperature sensor 3 respectively. 1 is also connected with alarm device 5 and wireless transmitter 6.

[0022] This embodiment also discloses a method for detecting the covering at the air outlet of a dehumidifier, including using the equipment for detecting the covering at the air outlet of a dehumidifier described in this embodiment, which specifically includes the following steps:

[0023] a. Pre-create a temperature lookup table for...

Embodiment 2

[0039] The general structure of a method for detecting the cover of a dehumidifier air outlet provided by this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, ΔT is 3 degrees, and ΔP is 10 Pa, and In this embodiment, the temperature lookup table for the relationship between the ambient temperature Ta and the air outlet temperature Tc and the temperature lookup table for the relationship between the air outlet temperature Tc and the air outlet wind pressure Tp still use Table 1 and Table 2 in Embodiment 1, In this embodiment, after the dehumidifier has been running for a period of time, the system automatically turns on the detection device at this time. At this time, the current ambient temperature Ta is 4°C collected by the second temperature sensor 3, and the air outlet temperature Tc is found according to Table 1. The maximum value Tcmax of an air outlet temperature corresponding to normal operation is 22°C, and the maximum value of...

Embodiment 3

[0041] The general structure of a method for detecting the cover of a dehumidifier air outlet provided by this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, ΔT is 10 degrees, and ΔP is 15 Pa, and In this embodiment, the temperature lookup table for the relationship between the ambient temperature Ta and the air outlet temperature Tc and the temperature lookup table for the relationship between the air outlet temperature Tc and the air outlet wind pressure Tp still use Table 1 and Table 2 in Embodiment 1, In this embodiment, after the dehumidifier has been running for a period of time, the system automatically turns on the detection device. At this time, the current ambient temperature Ta is collected by the second temperature sensor 3 as 30°C, and the air outlet temperature Tc is found according to Table 1. The maximum value Tcmax of an air outlet temperature corresponding to normal operation is 50°C, and the maximum value of the air...

Abstract

The invention discloses a dehumidifier air outlet covering detection device and detection method. The device comprises a controller, a first temperature sensor arranged at a dehumidifier air outlet and a second temperature sensor arranged on a dehumidifier and used for monitoring environment temperatures. An air pressure sensor is arranged at a fan outlet of the dehumidifier. The controller is connected with the first temperature sensor, the air pressure sensor and the second temperature sensor. An alarm device and a wireless transmission device are connected to the controller. According to the dehumidifier air outlet covering detection device and detection method, changes of the current environment temperatures and the current air pressure condition are detected in real time, then the current air pressure and the current environment temperatures are compared with the air pressure and air outlet temperature under normal conditions, once the data of comparison of the current air pressure and current environment temperatures and the air pressure and air outlet temperature under normal conditions reach the specific range and the process lasts for N minutes, it is indicated that an airoutlet is covered with clothes or other articles, work is stopped in time, and a user is reminded to clear away coverings; and therefore the abnormal conditions of the air outlet can be judged accurately, directly and effectively, finally, dehumidifier shell ageing can be avoided, and the service life of the dehumidifier can be prolonged.

Description

technical field [0001] The invention relates to the technical field of dehumidifier detection, in particular to a dehumidifier air outlet covering detection equipment and detection method. Background technique [0002] Dehumidifiers are also known as dehumidifiers, dryers, and dehumidifiers. They can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers, and belong to a part of the air-conditioning family. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water tank, a casing and a controller. Its working principle is: the humid air is sucked into the machine by the fan, and passes through the heat exchanger. At this time, the water molecules in the air are condensed into water droplets, and the dry air after treatment is discharged from the machine through the air outlet. This cycle keeps the indoor humidity. At a suitable relative humidity, if the air outlet is covered by clothes or towels during...
