Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner manufacturing, specifically to an air conditioner and a dust detection device for its air conditioner filter. Background Technology

[0002] In the structure of an air conditioner's indoor unit, the air filter is a crucial component. Its main function is to filter dust, bacteria, and other impurities from the air, ensuring fresh indoor air. Keeping the air filter clean helps improve air conditioning efficiency, indoor air quality, extend the air conditioner's lifespan, save energy, and reduce noise. At the same time, timely replacement or cleaning of the air filter can reduce the maintenance costs of the air conditioning system. A clean and effective filter can reduce the burden on the air conditioning equipment and decrease the likelihood of malfunctions.

[0003] However, the inventors discovered that currently available wall-mounted air conditioners do not have an automatic detection function for the amount of dust accumulation on the filter. Usually, it is necessary to manually disassemble the air conditioner and check the dust condition of the filter to determine whether it needs to be cleaned or replaced. Ordinary users do not pay much attention to the dust condition of the filter, and therefore do not clean the filter for a long time. This leads to environmental pollution, dust clogging the air intake of the air conditioner, and poor cooling effect when the air conditioner is working. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an air conditioner filter dust detection device, so as to solve the problems that manual filter inspection is cumbersome and that users cannot easily understand the dust status of the air conditioner filter.

[0006] In some embodiments, the controller has a preset threshold for dust status. The controller can compare the dust status with the threshold, and when the dust status exceeds the threshold, the controller issues an alarm signal.

[0007] In some embodiments, the air conditioner filter dust detection device further includes a display screen, which is disposed on the outer surface of the air conditioner and connected to the controller. The display screen is used to receive and display the dust status and alarm signals.

[0008] In some embodiments, the air conditioning filter dust detection device further includes a wireless communication module, which is connected to the controller and wirelessly connected to the user's electronic device. The wireless communication module is used to receive and transmit dust status and alarm signals to the electronic device.

[0009] In some embodiments, the transmitter is an infrared LED light, the first signal is the infrared light emitted by the infrared LED light to the air conditioner filter, the receiver is an infrared light detector, and the second signal is the infrared light passing through the filter.

[0010] In some embodiments, the transmitter is a laser, the first signal is the laser beam emitted by the laser to the air conditioner filter, the receiver is a laser beam detector, and the second signal is the laser beam that has passed through the filter.

[0011] In some embodiments, the number of transmitters is one or more.

[0012] In some embodiments, the number of receivers is one or more.

[0013] In some embodiments, the number of transmitters is equal to the number of receivers.

The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0023] Example 1

[0024] Please see Figure 1 and Figure 2 The air conditioning filter dust detection device 110 includes a transmitter 111, a receiver 112, and a controller (not shown in the figure). The transmitter 111, the controller, and the receiver 112 are connected in sequence. The transmitter 111 is disposed on one side of the air conditioning filter 140, and the receiver 112 is disposed on the other side of the air conditioning filter 140. The controller outputs the dust status based on the difference between a first signal emitted by the transmitter 111 and a second signal received by the receiver 112. In this embodiment, both the transmitter 111 and the receiver 112 are fixedly connected to the filter 140.

[0025] Example 2

[0026] Please see Figure 1 and Figure 2 The transmitter 111 is an infrared LED light. The first signal is the infrared light emitted by the infrared LED light onto the air conditioning filter 140. The receiver 112 is an infrared light detector. The second signal is the infrared light passing through the filter 140. After receiving the first and second signals, the controller's internal circuitry analyzes the differences to perform dust detection on the filter 140, thus obtaining the dust status on the filter 140.

[0027] The working principle is as follows: When the air conditioner 100 enters a dirty state, the infrared LED emits a beam of light. The infrared light detector installed on the other side of the air conditioner filter 140 detects different light intensities and outputs different current / voltage signals accordingly. That is, when the filter 140 is severely clogged, the infrared light detector receives a weak light intensity, and when the filter 140 is not clogged, the infrared light detector receives a stronger light intensity, outputting different magnitude current / voltage signals to the controller for comparison.

[0028] Example 3

[0029] Please see Figure 1 and Figure 2 The transmitter 111 is a laser, and the first signal is the laser beam emitted by the laser to the air conditioning filter 140. The receiver 112 is a laser beam detector, and the second signal is the laser beam that has passed through the filter 140. The controller's internal circuitry receives the first and second signals, analyzes the differences, and performs dust detection on the filter 140 to determine its dust status. The working principle is the same as in Embodiment 2, and will not be repeated here.

[0030] Example 4

[0031] Based on embodiments one to three, the controller has a preset threshold for the dust state. The controller can compare the dust state with the threshold. When the dust state exceeds the threshold, the controller issues an alarm signal.

[0032] Example 5

[0033] The dust detection device for the air conditioner filter 140 also includes a display screen (not shown in the figure). The display screen is located on the outer surface of the air conditioner 100 and is connected to the controller. The display screen is used to receive and display the dust status and alarm signals.

[0034] Example 6

[0035] The air conditioner filter 140 dust detection device also includes a wireless communication module (not shown in the figure). The wireless communication module is connected to the controller and wirelessly connected to the user's electronic device. The wireless communication module is used to receive and transmit dust status and alarm signals to the electronic device for the user's convenience.

[0036] It should be noted that this invention does not limit the number of transmitters 111 and receivers 112. The number can be flexibly configured according to system requirements and accuracy. Therefore, the number of transmitters 111 and receivers 112 is at least one, and the number can be equal or unequal. The connection mentioned in this invention can be a wired connection or a wireless connection. Therefore, this invention does not limit the location of the controller, as long as the specific location of the controller does not affect the normal operation of the air conditioner 100.

[0037] Example 7

[0038] Further, please refer to Figure 3 and Figure 4 This utility model also provides an air conditioner 100, which includes at least a front cover 120, an air conditioner body 130, and the aforementioned air conditioner filter dust detection device 110. The front cover 120 and the air conditioner body 130 cover the air conditioner filter dust detection device and the air conditioner filter 140. In this embodiment, the receiver 112 can also be fixed to the front cover 120, and the transmitter 111 can be fixed to the air conditioner body 130.

[0039] The beneficial effects of this utility model are as follows: the air conditioner filter dust detection device is configured as a transmitter, a receiver, and a controller, wherein the transmitter, controller, and receiver are connected in sequence. The transmitter is located on one side of the air conditioner filter, and the receiver is located on the other side of the air conditioner filter. The transmitter is used to send a first signal, and the receiver is used to receive a second signal. Since the controller can compare the difference between the first signal and the second signal, it outputs the dust status of the air conditioner filter, allowing users to easily understand the dust status of the air conditioner filter, thereby achieving the beneficial effects of protecting the air conditioner, improving air conditioner efficiency, improving indoor air quality, extending the life of the air conditioner, saving energy, and reducing noise.
