Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to an air conditioner. Background Art

[0002] With the change of people's lifestyle, air conditioning has become the choice of thousands of households in the hot summer. Among them, the problem of indoor condensation is one of the hot issues that consumers are concerned about.

[0003] The principle of condensation is as follows: the state of water vapor in humid air is determined by its partial pressure PV and the temperature t of the humid air, that is, point a on the water vapor PV diagram ( Figure 1 ); For unsaturated moist air, if the water vapor partial pressure PV is kept constant and the air is cooled to lower its temperature, although the water vapor content in the moist air will not change, the state of the water vapor will change along the PV constant pressure line a-c and reach saturation at point c. The temperature at point c is called the dew point temperature, expressed as t d It means that it is the saturation temperature for the water vapor partial pressure PV. If the temperature drops further, condensation will occur. Therefore, controlling the outlet air temperature and preventing the outlet air temperature from being too low is an important means to prevent condensation problems.

[0004] At the same time, as people's living standards improve, consumers pay more and more attention to health, including air quality. In order to meet consumer requirements, air purification parts are added when developing air conditioners. However, the better the purification effect of such parts, the greater the density, the greater the wind resistance, which reduces the air volume and leads to lower air outlet temperature, which poses a risk of condensation in the air conditioner.

[0005] Therefore, how to combine solving the condensation problem with improving the purification effect is an important issue in air-conditioning development. Summary of the invention

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0033] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0034] The present invention provides an air conditioner, please refer to Figures 2 to 10 , including a shell 10, a fan and a driving member, the driving member is connected to the fan, and the air conditioner also includes: a high-density filter 20 or a low-density filter, both of which are detachably connected to the shell 10; a detection member 30, used to detect whether the high-density filter 20 or the low-density filter is installed on the shell 10, and when it is detected that the high-density filter 20 is installed on the shell 10, the driving member is controlled to operate at a first speed; when it is detected that the low-density filter is installed on the shell 10, the driving member is controlled to operate at a second speed; wherein the first speed is greater than the second speed.

[0035] The air conditioner of the present invention is provided with a high-density filter 20 or a low-density filter, and the detection member 30 is used to detect whether the high-density filter 20 or the low-density filter is installed on the housing 10. When the detection member 30 detects that the high-density filter 20 is installed on the housing 10, the driving member is controlled to run at a first speed, that is, to increase the speed, which can optimize the purification effect and reduce the generation of condensation; when the detection member 30 detects that the low-density filter is installed on the housing 10, the driving member is controlled to run at a second speed, that is, to reduce the speed, thereby reducing noise and improving consumer satisfaction. The air conditioner solves the problem that the air conditioner in the prior art is prone to generate condensation.

[0036] It should be noted that high density and low density are relative to the impact on air volume. The high-density filter 20 has a great impact on the air volume. After the use of the high-density filter 20, the air volume will drop by more than 3%; the impact of the low-density filter on the air volume is within 3%, that is, the air volume drops by less than or equal to 3% after using the low-density filter.

[0037] Specifically, the driving member is a motor.

[0038] In the first embodiment, the air conditioner further comprises: a to-be-detected member 40, which is arranged on the high-density filter 20, and the detection member 30 is used to detect the to-be-detected member 40, so as to control the driving member to operate at a first speed when the detection member 30 detects the to-be-detected member 40; and to control the driving member to operate at a second speed when the detection member 30 does not detect the to-be-detected member 40. In a specific implementation, the air conditioner determines whether the air conditioner has a high-density filter 20 through the to-be-detected member 40.

[0039] In the first embodiment, the high-density filter 20 includes a filter body 21 and a frame 22 disposed around the filter body 21 ; the detected member 40 is detachably connected to the frame 22 ; or, the detected member 40 is integrally formed with the frame 22 .

[0040] In the first embodiment, the detection member 40 includes a connecting portion 41 and a triggering portion 42 disposed on the connecting portion 41 . The connecting portion 41 is connected to the high-density filter 20 , and the detection member 30 is used to detect the triggering portion 42 .

[0041] Specifically, the connecting portion 41 is a buckle, and the connecting portion 41 is snap-fitted with the frame 22. Such a configuration facilitates the installation of the component to be detected.

[0042] Optionally, the to-be-detected member 40 may be made of plastic or stainless steel.

[0043] In the first embodiment, the detection member 30 is a photoelectric switch or a micro switch.

[0044] Specifically, the micro switch has a driving rod 31. When the detected part 40 pushes the driving rod 31 to a predetermined position, the micro switch is turned on to control the driving part to run at a first speed; when the detected part 40 is separated from the driving rod 31, the micro switch is turned off; wherein, an insulating sleeve is provided on the driving rod 31.

[0045] Optionally, the insulating sleeve is made of plastic.

[0046] In specific implementation, when the micro switch is turned on, it indicates that the air conditioner is installed with a high-density filter 20, so as to control the driving part to run at a first speed; when the micro switch is turned off, it indicates that the air conditioner is installed with a low-density filter, so as to control the driving part to run at a second speed. The two states of the micro switch on and off correspond to different motor speeds, so that the air conditioner can ensure that no condensation problem occurs whether the high-density filter 20 is present or not.

[0047] In specific implementation, when the air conditioner is equipped with a high-density filter 20, the weight of the high-density filter 20 and the buckling structure of the filter mounting frame 60 and the housing 10 are used to press the detection member 40 downward as a whole, and the trigger portion 42 on the detection member 40 touches the driving rod 31 of the micro switch. When the detection member 40 is pressed downward as a whole to a certain extent, the micro switch starts to operate, that is, the micro switch is turned on.

[0048] In the first embodiment, the air conditioner includes a mounting box 50, which is arranged on the housing 10; the detection member 30 is arranged in the mounting box 50; the mounting box 50 is provided with an avoidance hole 51; when the detection member 30 is a micro switch, the detection member 40 is abutted against the driving rod 31 of the micro switch through the avoidance hole 51; when the detection member 30 is a photoelectric switch, the detection member 40 enters the mounting box 50 through the avoidance hole 51, so that the detection end of the photoelectric switch detects the detection member 40.

[0049] Specifically, the micro switch has a line interface, and the line interface of the micro switch is wrapped by an insulating member, and the insulating member is provided with a line hole for routing.

[0050] Optionally, the insulating element is made of plastic.

[0051] In specific implementation, the circuit interface and driving rod 31 of the micro switch cannot be touched, so the installation box 50 is designed, and the circuit interface of the micro switch is wrapped by an insulating member, leaving only one wire hole for wiring, so as to avoid touching the circuit interface of the micro switch; at the same time, the driving rod 31 of the micro switch is protected by an insulating sleeve to ensure that the driving rod 31 of the micro switch will not be directly touched. Such a setting improves electrical safety.

[0052] In the second embodiment, the housing 10 has an air inlet, and a high-density filter 20 or a low-density filter is arranged at the air inlet; the detection member 30 is an air volume detection member, and the air volume detection member is arranged on the inner side of the air inlet to detect the air volume entering the housing 10. When the air volume detection member detects that the air volume is less than the preset air volume, the driving member is controlled to operate at a first speed; when the air volume detection member detects that the air volume is greater than the preset air volume, the driving member is controlled to operate at a second speed. In specific implementation, the size of the air volume is used to determine whether the high-density filter 20 or the low-density filter is arranged at the air inlet. When the high-density filter 20 is arranged, due to the large wind resistance of the high-density filter 20, the air volume detected by the air volume detection member will be less than the preset air volume, thereby increasing the speed of the driving member to increase the air volume and reduce condensation.

[0053] Specifically, the air volume detection component includes an anemometer, which is used to detect the wind speed. The air volume detection component multiplies the detected wind speed by the cross-sectional area of ​​the air inlet to calculate the air volume, so as to compare the air volume with the preset air volume.

[0054] In the second embodiment, the air conditioner also includes an installation box 50, which is arranged on the shell 10; part of the structure of the detection member 30 is arranged in the installation box 50, and the installation box 50 is provided with an avoidance hole 51, and the detection end of the detection member 30 extends out of the installation box 50 through the avoidance hole 51 to detect the wind speed.

[0055] In this embodiment, the air conditioner further includes an installation box 50, and the detection member 30 is arranged in the installation box 50; the housing 10 has an installation recess 11, and at least part of the installation box 50 is arranged in the installation recess; and / or, the installation box 50 is provided with a first fastening hole 52, and the housing 10 is provided with a second fastening hole, and the installation box 50 is fixedly connected to the housing 10 by fasteners inserted in the first fastening hole 52 and the second fastening hole. Such an arrangement enables the detection member 30 to be arranged safely and reliably to play a detection role.

[0056] Specifically, the housing 10 includes a panel body, and the mounting recess 11 is disposed on the panel body.

[0057] In specific implementation, one end of the installation box 50 is inserted into the installation recessed portion 11 reserved on the panel body, and the other end is fixed with screws, so that the entire installation box 50 is simply and reliably fixed on the panel body.

[0058] In this embodiment, the air conditioner further includes: a filter mounting frame 60 detachably connected to the housing 10 ; wherein the high-density filter 20 and the low-density filter are both detachably connected to the filter mounting frame 60 .

[0059] Specifically, the high-density filter screen 20 and the low-density filter screen are both snap-connected to the filter mounting frame 60 .

[0060] Specifically, in other embodiments, the component to be detected 40 may be disposed on the filter mounting frame 60 .

[0061] Specifically, the micro switch and the mounting box are not necessarily separate, and can be made into an integral whole.

[0062] In specific implementation, when there is a high-density filter 20, the micro switch is triggered to start the action, and the controller program automatically increases the motor speed to prevent condensation problems. When there is no high-density filter (i.e., a low-density filter is installed), the micro switch is not triggered and does not work, and the controller program controls the motor to run at a default lower speed, thereby improving consumer satisfaction with the product. In other embodiments, it is not necessary to use the detection part signal control, and the remote control can be automatically switched to achieve the change of the driving part speed.

[0063] The present application solves the technical problem that the air conditioner can only choose between the condensation effect and the purification effect, but cannot have both.

[0064] The beneficial effect of the present application is that when the air conditioner is installed with a high-density filter 20, the motor speed is appropriately increased, which can not only optimize the purification effect but also ensure reliable condensation; when there is no high-density filter 20, that is, the air conditioner is installed with a low-density filter, the motor speed is appropriately reduced, reducing noise and improving consumer satisfaction.

[0065] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0066] The air conditioner of the present invention is provided with a high-density filter 20 or a low-density filter, and the detection member 30 is used to detect whether the high-density filter 20 or the low-density filter is installed on the housing 10. When the detection member 30 detects that the high-density filter 20 is installed on the housing 10, the driving member is controlled to run at a first speed, that is, to increase the speed, which can optimize the purification effect and reduce the generation of condensation; when the detection member 30 detects that the low-density filter is installed on the housing 10, the driving member is controlled to run at a second speed, that is, to reduce the speed, thereby reducing noise and improving consumer satisfaction. The air conditioner solves the problem that the air conditioner in the prior art is prone to generate condensation.
