Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and in particular relates to a humidity detection component, an air conditioner indoor unit, an air conditioner and a control method thereof. Background Art

[0002] With the maturation and advancement of current technology and the diversification of user needs, the range of air conditioner functions has rapidly expanded. Currently, many models include dehumidification functions, using a display (also known as a display panel) to display humidity values. To accurately measure humidity values, a through-hole structure is required at the location corresponding to the humidity sensor on the display to maintain air circulation and ensure accurate humidity measurement. However, in humid and rainy areas, the humidity sensor's long-term exposure to moist air can significantly reduce the lifespan of the electronic components, hindering the long-term use of the air conditioner. The present invention addresses this conflicting requirement: the sensor must be exposed to moist air for accurate measurements, while also preventing the long-term corrosion of the electrical components by moist air. Summary of the Invention

[0003] Therefore, the present invention provides a humidity detection component, an air conditioner indoor unit, an air conditioner and a control method thereof, which can solve the technical problem in the prior art that in order to accurately detect the air humidity, the humidity detection board is placed in a humid environment for a long time, resulting in the service life of the electronic components of the humidity detection board being reduced due to long-term erosion by humid air.

[0004] In order to solve the above problems, the present invention provides a humidity detection component for use in air conditioning equipment, the humidity detection component comprising:

[0007] In some embodiments,

[0008] The drying shielding component includes a drying box and a driving component for driving the drying box to translate. The drying box has an opening. When the drying shielding component is in the drying position, the air flow hole is inside the drying box. When the drying shielding component is in the humidity detection position, the air flow hole is outside the drying box. The drying shielding component switches between the drying position and the humidity detection position via the opening.

[0009] In some embodiments, the humidity detection component further includes:

[0010] An air conditioning panel body is provided with an installation groove, the humidity detection plate is assembled in the installation groove, the drying shielding component further includes a sliding base, the drying box and the sliding base are detachably connected, the sliding base is slidably connected to the air conditioning panel body, and the driving component drives the drying box to translate by driving the sliding base.

[0011] In some embodiments,

[0012] The sliding base comprises a bottom plate and a vertical plate which are perpendicular to each other, and the drying box comprises side walls which are parallel to the vertical plates. The side walls and the vertical plates are connected integrally via a snap-fit structure.

[0013] In some embodiments,

[0014] The buckle structure includes a fixing protrusion and two fixing hooks on the side wall. The two fixing hooks are arranged at intervals in the horizontal direction, and the fixing protrusion is located on the side of the two fixing hooks close to the bottom plate to form a triangular arrangement with the two fixing hooks. The vertical plate has an elastic arm that elastically buckles with the fixing protrusion. When the sliding base is assembled with the drying box, the end surface of the vertical plate away from the bottom plate is located in the hooking grooves of the two fixing hooks, so that the drying box is connected to the sliding base under the joint action of the fixing hooks, the fixing protrusion and the elastic arm.

[0015] In some embodiments,

[0016] The air conditioning panel body is constructed with two parallel and spaced sliding grooves, and rollers are provided on opposite sides of the bottom plate, the rollers slide in the sliding grooves, and the two parallel groove walls of the sliding grooves are spaced apart along the height direction of the vertical plate; and / or,

[0017] A rack extending along the sliding translation direction of the drying box is provided on the wall surface of the bottom plate away from the drying box.

[0018] In some embodiments,

[0019] The drying structure is detachably placed in the drying box; and / or the detection circuit board further has a display module.

[0020] The present invention also provides an indoor unit of an air conditioner, comprising the above-mentioned humidity detection component.

[0021] In some embodiments, the air conditioner indoor unit includes a heat exchanger. When the humidity detection assembly further includes an air conditioner panel body, the mounting groove is located above the heat exchanger and on the air inlet side of the heat exchanger.

[0022] The present invention also provides an air conditioner, comprising the above-mentioned air conditioner indoor unit.

[0023] The present invention also provides a method for controlling an air conditioner, which is used to control the above-mentioned air conditioner, comprising the following steps:

[0024] Get control instructions;

[0025] When the acquired control instruction is a detection plate dehumidification instruction, the drying shielding component is controlled to be in the drying position; or

[0026] When the acquired control instruction is a humidity detection instruction, the drying shielding component is controlled to be in the humidity detection position.

[0027] In some embodiments,

[0028] When the real-time relative humidity P1 of the air detected by the humidity sensor is greater than the preset humidity value P and the maintenance time is longer than the first time T, the dehumidification instruction of the detection plate is automatically issued; or,

[0029] The user triggers the dehumidification instruction of the detection plate.

[0030] In some embodiments,

[0031] When the real-time relative humidity P2 of the air detected by the humidity sensor is less than the preset humidity value P, the humidity detection instruction is automatically issued; or,

[0032] The user triggers the humidity detection instruction.

[0033] The present invention provides a humidity detection component, an air conditioner indoor unit, an air conditioner and a control method thereof, which have the following beneficial effects:

[0034] By providing a drying shielding component, the detection circuit board is placed in a dry position when dehumidification is required. The drying shielding component can block the air flow holes, thereby reducing the contact between the water vapor in the external environment and the detection circuit board. At the same time, the drying structure of the drying shielding component can also dry the air near the detection circuit board and reduce the air humidity around the detection circuit board, thereby effectively preventing the detection circuit board from being in a high humidity environment for a long time, which would cause the service life of the electronic components on the detection board to be reduced due to long-term erosion by humid air.

[0035] The drying box with an opening on one side can completely place the air flow hole inside the box cavity when drying is required, forming a relatively dry space near the air flow hole, effectively preventing the air inside the test circuit board from drying out;

[0036] The air conditioner panel body serves as a common assembly carrier for the humidity detection plate and the drying box, making the humidity detection assembly of the present invention more compact in structure. The drying box and the sliding base are connected in a detachable manner. This also facilitates the removal of the drying box from the sliding base when the drying effect of the drying box decreases and the drying structure needs to be replaced, thereby facilitating replacement of the drying structure.

[0037] The side wall and the vertical plate are connected by the aforementioned triangular fixed protrusions, two fixed hooks, and elastic arms to form a reliable locking of the drying box and the sliding base in the height direction, and the side wall and the vertical plate are also connected in the horizontal direction to ensure that the two are securely locked in the horizontal direction.

[0054] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] 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 "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0056] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0057] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0058] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0059] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0060] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0061] See also Figures 1 to 8 As shown, according to an embodiment of the present invention, a humidity detection component is provided for use in air conditioning equipment. The aforementioned air conditioning equipment may be, for example, an air conditioner indoor unit, a dehumidifier, or other equipment that requires a humidity detection device. The humidity detection component includes:

[0062] The humidity detection board 1 includes a mounting plate 11 and a detection circuit board (not labeled in the figure) connected to the mounting plate 11. The mounting plate 11 has an airflow hole 111. The humidity sensor of the detection circuit board is arranged in the airflow hole 111. It can be understood that the detection circuit board has corresponding electrical components and corresponding printed circuits. The humidity sensor detects the real-time relative humidity of the airflow circulating around it, and feeds the corresponding detection value back to the corresponding electrical component for necessary processing, and then executes the response strategy. This is a conventional technology in the field. The present invention does not intend to protect the specific structure and implementation of the detection circuit board. Therefore, it is not described here.

[0063] The drying shielding component 2 has a drying structure 23, and has a drying position that blocks the airflow circulation hole 111 to dry the airflow around the humidity sensor, and a humidity detection position away from the airflow circulation hole 111 to allow the airflow to flow into the airflow circulation hole 111. It can be understood that the drying shielding component 2 can be driven to switch between the aforementioned drying position and humidity detection position to adapt to different working conditions.

[0064] In this technical solution, by providing a drying shielding component 2, the detection circuit board is placed in a dry position when it needs to be dehumidified. It can block the air flow hole 111, thereby reducing the contact between water vapor from the external environment and the detection circuit board. At the same time, the drying structure 23 of the drying shielding component 2 can also dry the air near the detection circuit board and reduce the air humidity around the detection circuit board, thereby effectively preventing the detection circuit board from being in a high-humidity environment for a long time, which causes the service life of the electronic components on the detection board to be reduced due to long-term erosion by humid air.

[0065] It should be noted that the detection circuit board in the present application is wrapped in the mounting plate body 11 , and the position where it communicates with the outside is the aforementioned air flow hole 111 .

[0066] In a specific embodiment, the drying shielding component 2 includes a drying box 21 and a driving component (not shown in the figure) for driving the drying box 21 to translate. The drying box 21 has an opening 210. When the drying shielding component 2 is in the drying position, the air flow hole 111 is inside the drying box 21. When the drying shielding component 2 is in the humidity detection position, the air flow hole 111 is outside the drying box 21, and the drying shielding component 2 switches between the drying position and the humidity detection position via the opening 210.

[0067] In this technical solution, the drying box 21 having an opening 210 on one side can completely place the air flow hole 111 in the inner cavity of the drying box 21 when drying is required, thereby forming a relatively dry space near the air flow hole 111, effectively preventing the air in the detection circuit board from drying out.

[0068] At this time, as a preferred embodiment, the drying structure 23 is a desiccant detachably placed in the drying box 21, that is, the desiccant is placed in the internal space of the drying box 21, so that it is convenient to replace the drying structure 23 in time when the drying effect is not good, thereby ensuring a long-lasting and effective drying effect.

[0069] In a specific embodiment, the humidity detection component also includes: an air conditioning panel body 3, an installation groove 31 is constructed on the air conditioning panel body 3, the humidity detection plate 1 is assembled in the installation groove 31, the drying shielding component 2 also includes a sliding base 22, the drying box 21 and the sliding base 22 are detachably connected, the sliding base 22 is slidably connected to the air conditioning panel body 3, and the driving component drives the drying box 21 to move horizontally by driving the sliding base 22.

[0070] In this technical solution, on the one hand, the air conditioning panel body 3 serves as a common assembly carrier for the humidity detection plate 1 and the drying box 21, which can make the humidity detection component of the present invention more compact in structure; on the other hand, a detachable connection method is adopted between the drying box 21 and the sliding base 22, which also makes it convenient to remove the drying box 21 from the sliding base 22 when the drying effect of the drying box 21 is reduced and the drying structure 23 needs to be replaced, thereby facilitating the replacement of the drying structure 23.

[0071] See also Figures 3 to 6 As shown, in a specific embodiment, the sliding base 22 has a bottom plate 221 and a vertical plate 222 that are perpendicular to each other. Specifically, the vertical plate 222 is also roughly perpendicular to the bottom wall of the mounting groove 31. The drying box 21 has a side wall 211 parallel to the vertical plate 222. The side wall 211 and the vertical plate 222 are connected as a whole by a snap-fit structure.

[0072] In this technical solution, the drying box 21 and the sliding base 22 are detachably connected by a snap-fit connection, which facilitates assembly and disassembly of the two.

[0073] In some embodiments, as a specific example, the snap-fit structure includes a fixed protrusion 212 and two fixed hooks 213 on the side wall 211, the two fixed hooks 213 are arranged at intervals in the horizontal direction, and the fixed protrusion 212 is located on the side of the two fixed hooks 213 close to the bottom plate 221 to form a triangular arrangement with the two fixed hooks 213, and the vertical plate 222 has an elastic arm 223 that elastically buckles with the fixed protrusion 212. When the sliding base 22 is assembled with the drying box 21, the end surface of the vertical plate 222 away from the bottom plate 221 is in the hooking groove of the two fixed hooks 213, so that the drying box 21 is reliably connected to the sliding base 22 under the joint action of the fixed hook 213, the fixed protrusion 212, and the elastic arm 223.

[0074] In this technical solution, on the one hand, the side wall 211 and the vertical plate 22 are securely locked in the height direction by the aforementioned triangularly arranged fixing protrusions 212, two fixing hooks 213, and elastic arms 223. At the same time, the side wall 211 and the vertical plate 22 are securely locked in the horizontal direction by the horizontally fitting connection between the side wall 211 and the vertical plate 22. It should be noted that, see Figure 4 and Figure 5 As shown, a slot is provided below the elastic arm 223 on the vertical plate 22 , and the aforementioned fixing protrusion 212 is inserted into the slot, thereby limiting the left-right movement of the drying box 21 .

[0075] During installation, the two fixing hooks 213 of the drying box 21 are first overlapped on the top surface of the vertical plate 22, and the drying box 21 is pressed downward. The elastic properties of the elastic arms 223 of the vertical plate 22 are then used to abut against the fixing protrusions 212 of the drying box 21. At this time, under the combined action of the aforementioned structures, the freedom of the drying box 21 in six directions is completely restricted. When the air conditioner has been in operation for a long period of time and the drying structure 23 in the drying box 21 needs to be replaced regularly, the disassembly process of the drying box 21 is similar. After the elastic arms 223 are separated from the fixing protrusions 212, the two fixing hooks 213 are separated from the vertical plate 22, which is easy to operate.

[0076] See also Figure 2As shown, in some embodiments, two parallel and spaced sliding grooves 32 are constructed on the air-conditioning panel body 3, and rollers 224 are provided on opposite sides of the bottom plate 221. The rollers 224 slide in the sliding grooves 32, and the two parallel groove walls of the sliding grooves 32 are spaced apart along the height direction of the vertical plate 222. In this technical solution, the bottom plate 221 is slidingly connected to the air-conditioning panel body 3 through the rollers 224 respectively provided on its two sides, and has a smaller sliding contact surface. On the one hand, it can ensure smooth position switching of the drying box 21, and on the other hand, it can also reduce the loss of components caused by friction caused by sliding translation; more importantly, the two parallel groove walls of the aforementioned sliding grooves 32 are spaced apart along the height direction of the vertical plate 222, which can ensure the reliability of the sliding connection during the removal of the drying box 21 from the sliding base 22, and prevent the sliding base 22 from being disconnected from the air-conditioning panel body 3 during the removal process.

[0077] The bottom plate 221 is away from the wall of the drying box 21 (with Figure 3 The orientation shown is for reference only, i.e., a rack 225 extending along the sliding translation direction of the drying box 21 is provided on the bottom surface of the bottom plate 221. Two racks 225 can be provided, and the two aforementioned racks 225 are respectively spaced apart and arranged on opposite sides of the bottom plate 221. In this way, correspondingly, the aforementioned driving component can be, for example, a rotary motor, and the gear sleeved on the rotating shaft of the rotary motor is engaged with the aforementioned racks 225 respectively, so that the rotation of the rotary motor can be converted into the translational sliding of the drying box 21, and the position switching is reliable and smooth.

[0078] In a preferred embodiment, the detection circuit board also has a display module, which is electrically connected to the detection circuit board through an existing circuit design. It can be used to display the real-time humidity detected by the humidity sensor. In a more preferred embodiment, the display module can also be configured with a corresponding display light (such as an LED light). The display light turns on and off to prompt the user whether the air humidity near the detection circuit board is in a high humidity environment, so as to prompt the user to perform necessary operations.

[0079] According to an embodiment of the present invention, there is also provided an air conditioner indoor unit, comprising the above-mentioned humidity detection component.

[0080] In some embodiments, the air conditioner indoor unit includes a heat exchanger, and when the humidity detection component also includes an air conditioner panel body 3, the mounting groove 31 is located above the heat exchanger and on the air inlet side of the heat exchanger, so that the installation position of the humidity detection component has a larger space and can detect the humidity of the incoming air flow more accurately. It is understandable that the air conditioner indoor unit also includes a panel (also called a decorative panel) located on the outside of the aforementioned air conditioner panel body 3, which is detachably assembled on the outside of the air conditioner panel body 3 to block part of the structure of the humidity detection component and enhance the appearance of the air conditioner indoor unit. The panel has a corresponding window to allow the user to view the information on the display module of the humidity detection component having a display module. When the aforementioned humidity detection component needs to be maintained, for example, when the drying structure 23 in the drying box 21 needs to be replaced, the panel can be removed from the air conditioner panel body 3, and then the disassembly and assembly can be performed according to the aforementioned disassembly and assembly steps of the drying box 21.

[0081] According to an embodiment of the present invention, there is further provided an air conditioner, comprising the above-mentioned air conditioner indoor unit.

[0082] According to an embodiment of the present invention, there is also provided a method for controlling an air conditioner, for controlling the above-mentioned air conditioner, comprising the following steps:

[0083] Get control instructions;

[0084] When the acquired control instruction is a detection plate dehumidification instruction, the drying shielding component 2 is controlled to be in the drying position; or,

[0085] When the acquired control instruction is a humidity detection instruction, the drying shielding component 2 is controlled to be in the humidity detection position.

[0086] In this technical solution, when the detection circuit board needs to be dehumidified, it is placed in a dry position, which can block the air flow hole 111, thereby reducing the contact between the water vapor in the external environment and the detection circuit board. At the same time, the drying structure 23 of the drying shielding component 2 can also dry the air near the detection circuit board and reduce the air humidity around the detection circuit board, thereby effectively preventing the detection circuit board from being in a high humidity environment for a long time, which causes the service life of the electronic components on the detection board to be reduced due to long-term erosion of moist air.

[0087] The issuance of the aforementioned detection board dehumidification instruction can be automatically triggered or manually triggered according to personal needs. Specifically, the automatic trigger is when the real-time relative humidity P1 of the air detected by the humidity sensor is greater than the humidity preset value P and the maintenance time is longer than the first time T. At this time, it is determined that the detection circuit board is easily damaged if it is in such a humid environment for a long time. Therefore, the detection board dehumidification instruction is automatically issued; and the manual trigger can be that the user triggers the corresponding control button to trigger the detection board dehumidification instruction.

[0088] By the same token, the aforementioned humidity detection instruction can also be triggered automatically or manually according to personal needs. Specifically, automatic triggering means that when the real-time relative humidity P2 of the air detected by the humidity sensor is less than the preset humidity value P, the humidity detection instruction is automatically issued; and manual triggering means that the user triggers the corresponding control button to trigger the humidity detection instruction.

[0089] The aforementioned preset humidity value P and the first time T can be set by the user according to actual needs, for example, it can be 70%, and the aforementioned first time can be 30 minutes.

[0090] In another embodiment, when the aforementioned drying box 21 is in the drying position, the display light in the display module can be in a flashing state to remind the user that the detection circuit board needs to be moisture-proofed at this time. At this time, the user can decide whether to perform further moisture-proof operations based on his own judgment, thereby improving the human-computer interaction experience.

[0091] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
