Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit, a sterilization control method, a control device, an air conditioner and a storage medium. Background Art

[0002] Current air conditioners are generally equipped with negative ions, but the effect of negative ions on sterilization and disinfection of the air conditioner is far from enough. In addition to negative ions, our air conditioners are also equipped with filters. The function of the indoor filter of the hanging machine is mainly to filter out dust and impurities in the air intake of the indoor machine. It is worth noting that the filter does not have the function of disinfection and sterilization. On the contrary, over time, the filter that accumulates dust will breed bacteria and other harmful substances. Dust and other substances will also enter the indoor machine through the position of the middle frame filter, and the dust inside the indoor machine is not easy to clean. Summary of the invention

[0003] The problem solved by the present invention is how to prevent dust from accumulating at the air inlet of the air conditioner, and the air conditioner can be self-cleaned intelligently to make the air blown out healthier.

[0004] To solve the above problems, the present invention provides an air-conditioning indoor unit, comprising an air inlet and a front panel; the air-conditioning indoor unit also comprises a cover plate and a cover plate driving device; the cover plate driving device drives the cover plate to move between the air inlet and the front panel so that the cover plate can open or close the air inlet.

[0005] The present invention adopts a cover plate driving device to drive the cover plate to move back and forth, so that when the air conditioner is in a turned-off state, the cover plate moves to above the air inlet of the air conditioner, preventing external dust from falling into the filter net from above the air inlet when the air conditioner is idle; it plays a dust-proof role and makes the air blown out by the air conditioner healthier.

[0006] Furthermore, a sterilization device is provided on one side of the cover plate covering the air inlet, a filter screen is provided at the air inlet, and the cover plate can cover the filter screen.

[0007] During the movement of the cover, by adjusting the placement of the cover, the ultraviolet lamp group can sterilize the indoor air and the inside of the air-conditioning indoor unit; realize the switching of different sterilization modes and increase the sterilization range; the filter is used to filter dust; the cover is set to cover the filter to play a dust-blocking role and prevent external dust from falling into the filter from the air inlet.

[0008] Furthermore, the air conditioner indoor unit includes an air inlet panel, and the cover plate driving device can drive the cover plate to be positioned at an angle of 45°-75° with the air inlet panel.

[0009] By driving the cover plate to be positioned at an angle of 45°-75° with the air inlet panel, ultraviolet rays can be better irradiated into the room for sterilization during indoor sterilization.

[0010] Furthermore, the cover plate driving device includes: a stepper motor, which is arranged at one end of the air-conditioning housing; a connecting rod, one end of which is fixedly connected to the cover plate; wherein the stepper motor is used to drive the connecting rod to rotate around the other end of the connecting rod.

[0011] The connecting rod is connected between the stepping motor and the cover plate, so that when the stepping motor rotates, the connecting rod drives the cover plate to rotate around the output shaft of the stepping motor, thereby realizing the movement of the cover plate.

[0012] Furthermore, the connecting rod includes: a first connecting rod and a second connecting rod, the first connecting rod is vertically fixedly connected to the second connecting rod, and the first connecting rod is fixedly connected to the cover plate; wherein an axial hole is arranged at the end of the second connecting rod, the axial hole is sleeved on the output shaft of the stepper motor, and a moving gap is formed between the second connecting rod and the cover plate.

[0013] The first connecting rod is vertically fixedly connected to the second connecting rod, so that the connecting rod is L-shaped, which facilitates the cover plate to rotate through the connecting rod; at the same time, the setting of the moving gap increases the rotation range of the cover plate; thereby increasing the sterilization range of the ultraviolet lamp group at different rotation angles of the cover plate.

[0014] Furthermore, the connecting rod is an electric telescopic rod, one end of the electric telescopic rod is fixedly connected to the cover plate, and the other end of the electric telescopic rod is fixedly connected to the stepping motor.

[0015] By setting the connecting rod as an electric telescopic rod, the rotation of the cover plate can be better achieved.

[0016] Furthermore, the air conditioner indoor unit is provided with a human body sensing device, and the human body sensing device is used to detect whether there is a user in the room.

[0017] The human body sensing device is set up to identify whether there is someone in the room before sterilization, thereby improving the safety of sterilization and improving the intelligent sterilization level of the device.

[0018] Furthermore, the human body sensing device is an infrared sensor or an image sensor.

[0019] The setting of the infrared sensor or the image sensor is easy to install and can identify whether a user is present with high recognition accuracy.

[0020] Furthermore, the cover plate is made of PVC material.

[0021] Made of PVC material, it has low cost, good flame retardancy, wear resistance, light weight and is easy to install.

[0022] The present invention also provides a sterilization control method for an air-conditioning indoor unit, using the air-conditioning indoor unit described in any of the above preferred items, wherein the indoor unit sterilization mode includes an air-conditioning internal sterilization mode and an indoor sterilization mode; wherein, when the air-conditioning internal sterilization mode is executed, the cover plate covers the air inlet, and the interior of the air-conditioning is sterilized by using the sterilization device arranged on the inner side of the cover plate; when the indoor sterilization mode is executed, the cover plate is lifted, the air-conditioning ventilation mode is turned on, and the air-conditioning ventilation mode is turned on by using the sterilization device arranged on the inner side of the cover plate.

[0023] The sterilization device sterilizes the indoor air.

[0024] It is understandable that users can turn on the sterilization mode according to sterilization needs. When the air conditioner indoor unit performs indoor sterilization or internal sterilization mode, the room and / or the inside of the air conditioner indoor unit are sterilized to make the air blown out by the air conditioner healthier; at the same time, it is also more energy-saving and environmentally friendly.

[0025] Furthermore,

[0026] When the sterilization mode is turned on, detect whether there is a user in the room;

[0027] When there is a user in the room, the air conditioner internal sterilization mode is executed;

[0028] When there is no user in the room, get the time interval from the last sterilization .

[0029] It can be understood that when the presence of someone is detected in the indoor sensing area, the cover plate maintains the position when the air conditioner is turned off, that is, it covers the top of the air inlet, so that a closed space is formed inside the air conditioner indoor unit to perform internal sterilization of the air conditioner indoor unit, thereby preventing ultraviolet rays from leaking out and causing harm to people in the sensing area during the internal sterilization process.

[0030] Furthermore,

[0031] When the time interval Greater than the preset time interval , the internal sterilization mode begins to be executed;

[0032] When the air conditioner internal sterilization mode is executed for a preset time Then, enter the indoor sterilization mode;

[0033] When the indoor sterilization mode is executed After a certain time, the sterilization mode is turned off;

[0034] When the time interval Less than or equal to the preset time interval When the sterilization mode is turned off, the cover is controlled to move to the front of the front panel, and the normal working mode of the air conditioner is turned on.

[0035] On the one hand, it prevents people from being in the sensing area to avoid the harm of ultraviolet rays to the human body during indoor sterilization; on the other hand, by comparing the time interval and preset time intervals , to determine whether to execute the indoor sterilization mode; when the time interval is detected Less than or equal to the preset time interval When it is, it means that the sterilization time is too short, and sterilization is not needed temporarily. The sterilization mode is turned off and the normal working mode is started to save energy and electricity; on the contrary, the cover plate is rotated to an angle of 60° with the horizontal plane where the air inlet is located, and the air guide plate is opened to allow ultraviolet rays to directly irradiate the indoor environment for indoor sterilization, making sterilization more economical, reasonable, scientific and effective.

[0036] Furthermore, ,in: To detect indoor wind speed, is the volume of the room space, is the correction factor, and .

[0037] By obtaining different room volumes V and the detected indoor wind speed, the preset sterilization time is calculated. , ensuring the sterilization effect in rooms of different sizes and indoor wind speeds. The correction coefficient K is a correction value provided based on the influence of other external factors to ensure the effectiveness of air conditioning sterilization under the influence of different environmental factors.

[0038] Furthermore, when the normal working mode of the air conditioner is turned on, the cover plate moves to the front of the front panel; when the air conditioner indoor unit is in a closed state, the cover plate covers the air inlet.

[0039] It is understandable that when the normal working mode is turned on, the cover plate moves to the front of the front panel, which facilitates air circulation and improves the efficiency of normal working modes such as air conditioning cooling, heating or dehumidification. When the air conditioner indoor unit is in the off state, the cover plate covers the air inlet, preventing external dust from falling into the air inlet.

[0040] Furthermore, when the indoor sterilization mode is turned on, the cover is lifted by 45°-75° to facilitate direct ultraviolet radiation into the room.

[0041] The present invention further provides an air conditioning control device, which is used to control the air conditioning indoor unit described in any one of the above preferred items, comprising:

[0042] A first execution module, configured to control the cover plate to cover the air inlet when executing an air conditioner interior sterilization mode, and sterilize the interior of the air conditioner using a sterilization device disposed on the inner side of the cover plate;

[0043] The first execution module is used to control the cover plate to be lifted, turn on the air conditioning and ventilation mode, and sterilize the indoor air using the sterilization device arranged on the inner side of the cover plate when the indoor sterilization mode is executed.

[0044] The present invention also provides a storage medium, which stores a computer program. When the computer program is read and executed by a processor, the air conditioner indoor unit where the storage medium is located is controlled to implement the sterilization control method described in any of the above preferred items.

[0045] The present invention also provides an air conditioner, characterized by comprising the air conditioner indoor unit described in any one of the above preferred items.

[0046] The present invention has the following beneficial effects:

[0047] 1) When the air conditioner is turned off, the cover can be moved to the top of the air inlet of the air conditioner and closed to prevent external dust from falling into the filter from the air inlet, playing a dust-proof role and making the air blown out by the air conditioner healthier;

[0048] 2) The ultraviolet lamp group is set on a movable cover. By adjusting the placement of the cover, the indoor air and the inside of the air conditioner indoor unit can be sterilized; the switching of different sterilization modes is realized and the sterilization range is increased;

Figure 4-5As shown, when the air conditioner indoor unit 100 is in the open state, the cover plate 102 moves to the front of the front panel 201. This embodiment adopts a movable cover plate 102. When the air conditioner is in the off state, the cover plate 102 moves to the top of the air inlet 702 of the air conditioner and covers the air inlet 702 to prevent external dust from falling into the filter 401 from the air inlet 702 when the air conditioner is idle; it plays a role in dust prevention and makes the air blown out by the air conditioner healthier.

[0068] Further, such as Figure 5 As shown, an air guide plate 106 is also provided at the front panel 201 , and an air outlet is provided at the air guide plate 106 .

[0069] Embodiment 2:

[0070] like Figure 1 As shown, the air-conditioning indoor unit 100 also includes a cover plate driving device, an air inlet panel 202, and a connecting rod 701; the air inlet panel 202 is located at the top of the air-conditioning indoor unit 100; the cover plate driving device is, for example, a stepper motor 103, and the stepper motor 103 is installed below the air inlet panel 202; the stepper motor 103 is connected to the cover plate 102 through the connecting rod 701, so that the cover plate 102 rotates around the output shaft of the stepper motor 103 under the action of the stepper motor 103.

[0071] Specifically, Figure 1 and Figure 6 As shown, the stepper motor 103 is arranged at one end of the air-conditioning housing 101, and is close to the side of the air inlet 702; the connecting rod 701 includes: a first connecting rod 7011 and a second connecting rod 7012, one end of the first connecting rod 7011 is fixedly connected to the cover plate 102 covering one side of the air inlet 702; the other end is vertically fixedly connected to one end of the second connecting rod 7012, and the other end of the second connecting rod 7012 is provided with an axial hole 703, which is fixedly connected to the output shaft of the stepper motor 103 through the axial hole 703.

[0072] Furthermore, a moving gap 704 is formed between the second connecting rod 7012 and the cover plate 102 , so that the front panel 201 can enter the moving gap 704 during the rotation of the cover plate 102 , thereby realizing the rotation of the cover plate 102 at different angles and increasing the rotation range of the cover plate 102 .

[0073] Furthermore, the length of the moving gap 704 is smaller than the width of the cover plate 102 , and the width of the moving gap 704 is larger than the thickness of the front panel 201 , so that the cover plate 102 can be rotated to the front of the front panel 201 .

[0074] Embodiment 3:

[0075] like Figure 7 As shown, the connecting rod 701 includes: a first connecting rod 7011 and a second connecting rod 7012 , and an axial hole 703 provided at the end of the second connecting rod 7012 .

[0076] Specifically, the stepper motor 103 is provided with an output shaft 1031, which passes through the air conditioner housing 101 and is vertically fixedly connected to one end of the second connecting rod 7012 through the shaft hole 703. The second connecting rod 7012 is an electric telescopic rod, and the other end of the second connecting rod 7012 is vertically fixedly connected to one end of the first connecting rod 7011; the other end of the first connecting rod 7011 is fixedly connected to one side of the cover plate 102. The air conditioner indoor unit 100 is also provided with a second connecting rod 7012 and a first connecting rod 7011 on the other side relative to the stepper motor 103, one end of the first connecting rod 7011 is fixedly connected to the other side of the cover plate 102, and the other end of the first connecting rod 7011 is connected to one end of the second connecting rod 7012; the other end of the second connecting rod 7012 is rotatably connected to a rotating shaft horizontally arranged in the air conditioner indoor unit 100; the rotating shaft can rotate in the horizontal direction.

[0077] When the indoor sterilization work is started, the second connecting rods 7012 on both sides extend upward to lift the cover plate 102 to reach the rotation height; the stepper motor 103 rotates in the first direction, such as forward rotation, so that the cover plate 102 rotates to the indoor sterilization angle to perform indoor sterilization;

[0078] When the normal working mode is turned on, the second connecting rods 7012 on both sides extend upward to lift the cover plate 102 to reach the rotation height; the stepper motor 103 rotates in the first direction, such as forward rotation, so that the cover plate 102 rotates to the front of the front panel 201;

[0079] When the air conditioner indoor unit 100 is turned off, the stepper motor 103 rotates in the second direction, such as reverse rotation, so that the cover plate 102 rotates to above the air inlet 702; at this time, the second connecting rods 7012 on both sides shrink downward, and the cover plate 102 covers the air inlet 702.

[0080] Embodiment 4:

[0081] like Figure 6 As shown, a sterilization device is provided on one side of the cover plate 102 covering the air inlet 702. The sterilization device may be, for example, an ultraviolet lamp group 104. The ultraviolet lamp groups 104 are interconnected by electric wires 105. The setting of the ultraviolet lamp group 104 can sterilize the room and the interior of the air conditioner indoor unit 100.

[0082] Specifically, when the cover plate 102 moves to the air inlet 702 and covers the air inlet 702, the ultraviolet lamp group 104 is driven to move into the air inlet 702, and the ultraviolet lamp group 104 is turned on to execute the internal sterilization mode of the air conditioner indoor unit 100, thereby achieving the effect of sterilizing the inside of the air conditioner indoor unit 100; Fig. 9As shown, when the cover plate 102 moves and rotates to form an angle of 60° with the air inlet panel 202, the indoor sterilization mode is executed, and the ultraviolet lamp group 104 sterilizes the room. By adjusting the placement of the cover plate 102, the switching of different sterilization modes is realized and the sterilization range is increased.

[0083] Furthermore, the ultraviolet lamp group 104 is embedded in the cover plate 102 to facilitate the rotation of the cover plate 102.

[0084] Furthermore, in internal sterilization mode,

[0085] like Figure 8 As shown, the cover plate 102 covers the air inlet 702, and the interior of the air-conditioning indoor unit 100 is sealed. On the one hand, it prevents the internal ultraviolet rays from irradiating the user and affecting the user's health; on the other hand, the closed sterilization environment greatly improves the internal sterilization and cleaning effect of the air-conditioning indoor unit 100.

[0086] Furthermore, in indoor sterilization mode,

[0087] like Fig. 9 As shown, the cover plate 102 and the air inlet panel 202 form a 60° angle, so that ultraviolet rays can irradiate the room and sterilize the indoor air; the setting of the 60° angle reduces the gap between the cover plate 102 and the front panel 201 of the air conditioner indoor unit 100, and at the same time, raises the irradiation angle of the ultraviolet lamp group 104 to prevent ultraviolet rays from passing through the gap between the cover plate 102 and the front panel 201 of the air conditioner indoor unit 100 and irradiating the user, affecting health. For example, when the air conditioner indoor unit 100 is in the indoor sterilization mode, the angle between the cover plate 102 and the horizontal plane of the air inlet panel 202 can also be as follows: Fig.10 The 45° angle shown in the figure; or other angles such as 50°, 55°, 65°, 70°, 75°, etc. The specific angle setting during the indoor sterilization mode can be set according to different installation environments and installation requirements. The corresponding safety angle setting can ensure the safety of ultraviolet radiation while sterilizing and disinfecting the indoor air.

[0088] Furthermore, in normal working mode,

[0089] like Fig.11 As shown, the cover 102 is rotated to the front of the front panel 201 under the action of the stepper motor 103. At this time, the ultraviolet lamp group 104 is located between the cover 102 and the front panel 201. At this time, the air inlet 702 is in a fully open state, which speeds up the air circulation inside the air-conditioning indoor unit 100 and the room, and improves the working efficiency of the air-conditioning in cooling, heating or dehumidification modes.
