Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

It should be noted that the type of the indoor unit 100 of the air conditioner according to the embodiment of the present invention is not limited, and the indoor unit may be, for example, an on-hook air conditioner, a cabinet air conditioner, or the like. For simplicity of description, only the air conditioning indoor unit 100 according to the embodiment of the present invention is described as an example of a hollow wall-mounted air conditioning indoor unit 100, and after reading the technical solutions described below, it is obvious that the air conditioning indoor unit 100 according to the embodiment of the present invention can also be embodied in other types of air conditioning indoor units 100, and details are not described herein.

An air conditioning indoor unit 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, an air conditioning indoor unit 100 according to an embodiment of the present invention includes: the water-saving air conditioner comprises a machine shell assembly 1, a heat exchanger component (not shown), a fan component (not shown) and a water-receiving tray 2. The cabinet assembly 1 includes a chassis 11, a face frame 12, and a panel (not shown), wherein the face frame 12 is connected to the chassis 11 and defines an installation space 13, the panel is disposed on the face frame 12, and the heat exchanger component and the fan component are disposed in the installation space 13. Therefore, the installation space 13 defined by the face frame 12 and the chassis 11 can better accommodate the heat exchanger component and the fan component, so that the shell assembly 1 has a good protection effect on the heat exchanger component and the fan component, and the operation stability and the anti-interference capability of the heat exchanger component and the fan component can be improved.

The panel can be arranged to prevent the heat exchanger and the fan from being exposed in the installation space 13, so as to improve the appearance of the indoor unit 100. On the other hand, the panel can better prevent dirt such as dust in the indoor space from entering the installation space 13, so as to keep the installation space 13 clean and sanitary, and is beneficial to creating a clean and healthy breathing environment for users. Meanwhile, adverse effects on the heat exchanger component and the fan component due to dust accumulation are prevented, so that the operation stability of the heat exchanger component and the fan component is further improved.

Further, the fan component can drive the air to flow, so that the air in the installation space 13 and the indoor space is forced to circulate, and the heat exchanger component can exchange heat with the air flowing through the heat exchanger component well. For example, the heat exchanger component may release heat to the air when the indoor unit 100 is in the heating mode, and may absorb heat from the air when the air conditioner is in the cooling mode.

Specifically, in the process of adjusting the temperature of the indoor unit 100 of the air conditioner, the fan component may drive the air in the indoor space to enter the installation space 13, and the air contacts the heat exchanger component to exchange heat, so as to complete the temperature rise or temperature reduction adjustment of the air, and then the air after temperature rise or temperature reduction adjustment is discharged from the installation space 13 and into the indoor space under the driving of the fan component, so as to gradually complete the temperature adjustment of the indoor space.

Wherein, the water pan 2 is arranged below the heat exchanger component. It can be understood that, during the operation of the indoor unit 100, for example, when the indoor unit 100 is in the cooling mode, when the air in the indoor space contacts the heat exchanger component, the temperature of the heat exchanger component is low, so that the water vapor in the air is easily condensed on the surface of the heat exchanger component, thereby generating condensed water. Therefore, during operation of the indoor unit 100, the condensed water generated in the heat exchanger member may drip down along the heat exchanger member and into the water receiving tray 2. Therefore, the condensed water generated during the operation of the indoor unit 100 of the air conditioner can be collected well through the water receiving tray 2, so that the risk that the condensed water directly drips from the indoor unit 100 of the air conditioner is avoided.

Furthermore, a drain hole 21 is provided on the water pan 2. That is, the condensed water collected in the drain pan 2 can be drained out of the drain pan 2 through the drain hole 21. Specifically, the water containing space on one end of the drain hole 21 is communicated with the water receiving tray 2, and the other end of the drain hole 21 can be communicated with the drainage pipeline, so that the condensed water collected by the water receiving tray 2 can be drained into the drainage pipeline through the drain hole 21 in time, and the condensed water is prevented from being remained in the water receiving tray 2 for a long time.

Therefore, the condensed water can be well prevented from overflowing from the water receiving disc 2 beyond the upper limit of the capacity of the water receiving disc 2, so that the direct dripping of the overflowed condensed water from the indoor unit 100 of the air conditioner and the safety risk of the circuit contact with the indoor unit 100 of the air conditioner are avoided, and the safety of the indoor unit 100 of the air conditioner can be improved. Secondly, bacteria or sludge which pollute the internal environment of the indoor unit 100 of the air conditioner due to the residual condensed water can be better avoided, and a clean and healthy breathing environment is favorably created for users.

As shown in fig. 3 and 4, a maintenance hole 121 is formed in the face frame 12, and the drainage hole 21 is observed or dredged through the maintenance hole 121. It can be understood that, in the operation process of the indoor unit 100 of the air conditioner, dirt such as dust in indoor air enters the indoor unit 100 of the air conditioner along with the airflow, and then enters the water pan 2 along with the condensed water when the water vapor condenses, and along with the increase of the accumulated amount of dirt, the blockage of the drain hole 21 is easily caused, and the drainage of the water pan 2 is further affected.

Therefore, through setting up maintenance hole 121 for the user can directly observe and learn whether wash port 21 blocks up at present, when wash port 21 takes place to block up, the user can use dredging tool 3 to stretch into maintenance hole 121 to clear up the foreign matter in wash port 21 fast, thereby realize the mediation operation of wash port 21, in order to guarantee that wash port 21 can discharge water smoothly. This reduces the difficulty in observing and dredging the drain hole 21, and thus can reduce the difficulty in maintaining the indoor air conditioning unit 100.

Moreover, since the maintenance hole 121 is located on the face frame 12, the face frame 12 does not need to be detached from the indoor unit 100 of the air conditioner during the observation and dredging process of the drain hole 21, thereby reducing the steps in the maintenance process of the drain hole 21, and further reducing the difficulty in maintenance of the indoor unit 100 of the air conditioner.

It should be noted that the dredging tool 3 can be an elongated object, such as a screwdriver, as shown in fig. 5-7, which is sequentially inserted through the maintenance hole 121 and the drainage hole 21 to remove the foreign matter in the drainage hole 21; the dredging tool 3 can also be a water spraying device, part of the water spraying device extends into the maintenance hole 121, and the water outlet end of the water spraying device is close to the drain hole 21 so as to clean foreign matters in the drain hole 21 through water spraying impact; the dredging tool 3 can also be an air blowing device, such as an air blowing gun or a dust blowing gun, wherein a part of the air blowing gun extends into the maintenance hole 121, and an air outlet end of the air blowing gun is close to the drain hole 21 so as to clean foreign matters in the drain hole 21 through the impact of air outlet. There is no particular limitation on the type of pull through 3.

According to the air-conditioning indoor unit 100 provided by the embodiment of the utility model, the maintenance hole 121 capable of observing or dredging the drain hole 21 is formed on the face frame 12, so that a user can directly observe whether foreign matter blockage exists in the drain hole 21 through the maintenance hole 121 without detaching the face frame 12, and when the foreign matter blockage exists in the drain hole 21, the user can quickly clean the foreign matter in the drain hole 21 through the maintenance hole 121, so that the dredging difficulty of the drain hole 21 can be reduced, and the maintenance difficulty of the air-conditioning indoor unit 100 can be further reduced.

In some embodiments of the utility model, the panel is switchable between an open state and a closed state. That is, the panel may be adjusted to an open state or a closed state according to a use requirement. In some examples of the utility model, the faceplate may be removably attached to the face frame 12, i.e., the faceplate may be completely removed from the face frame 12, e.g., the faceplate may be secured to the face frame 12 by a snap-fit. Therefore, in the process of daily maintenance or repair of the heat exchanger part or the fan part in the face frame 12, the panel is directly and completely detached from the face frame 12, so that the panel can be well prevented from interfering the operation of maintenance personnel, and meanwhile, the panel can be prevented from shielding part of parts of the air-conditioning indoor unit 100, and the maintenance difficulty of the air-conditioning indoor unit 100 can be reduced.

In other examples of the utility model, the panel may be movably connected to the face frame 12, for example, one end of the panel may be pivotally connected to the face frame 12, i.e., the panel may be pivotally connected to the face frame 12. In one specific example, the upper end of the panel is pivotally connected to the face frame 12 so that the panel can be rotated by a certain angle about the connection position of the panel to the face frame 12, thereby completing the switching of the open state and the closed state. Thus, the difficulty of switching the panel between the open state and the closed state is reduced.

Wherein, when the panel is in the closed state, the panel shields the maintenance hole 121. Specifically, when the panel is in the closed state, the panel can be better shielded at the end of the maintenance hole 121 far from the water discharge hole 21. Therefore, when the panel is in a closed state, the maintenance hole 121 can be prevented from being exposed, and the influence of the maintenance hole 121 on the appearance of the air conditioning indoor unit 100 can be avoided. Meanwhile, the panel in the closed state can better prevent dirt such as dust in the external space from directly entering the installation space 13 or the water receiving tray 2 through the maintenance hole 121, so that the blockage of the drain hole 21 caused by dust accumulation can be avoided, the cleanness and the sanitation of the inside of the indoor unit 100 of the air conditioner can be kept, and a healthy and safe breathing environment can be created for a user.

Further, the maintenance hole 121 is visible from the outside when the panel is in the open state. The outer portion here means a side of the face frame 12 away from the water discharge hole 21, i.e., an outer side of the face frame 12. That is, when the panel is in the open state, the user or the maintenance person can directly observe the state of the drainage hole 21 through the maintenance hole 121 from the side of the face frame 12 away from the drainage hole 21, that is, the outer side of the face frame 12, and can dredge the drainage hole 21 by the dredging tool 3 passing through the maintenance hole 121 when the drainage hole 21 is blocked by the foreign matter, so that the dredging difficulty of the drainage hole 21 can be reduced, and the maintenance difficulty of the air-conditioning indoor unit 100 can be reduced.

Specifically, when the indoor unit 100 of the air conditioner is in the normal operation state, the panel is in the closed state, so that the appearance attractiveness of the indoor unit 100 of the air conditioner is improved, and meanwhile, the cleanness and sanitation inside the indoor unit 100 of the air conditioner are favorably kept, so that a healthy and safe breathing environment can be created for users. When maintenance of the drain hole 21 is required, the panel is switched from the closed state to the open state, so that a user or a maintenance person can directly observe or dredge the drain hole 21 through the maintenance hole 121, the face frame 12 does not need to be detached, and maintenance difficulty of the drain hole 21 is low.

In some embodiments of the present invention, the inner diameter of the maintenance hole 121 increases in a direction from the outside of the face frame 12 to the inside of the face frame 12. The outer side of the face frame 12 refers to the side of the face frame 12 away from the water-receiving tray 2, the inner side of the face frame 12 refers to the side of the face frame 12 close to the water-receiving tray 2, and the maintenance hole 121 extends from the side of the face frame 12 away from the water-receiving tray 2 to the side close to the water-receiving tray 2. That is, the inner diameter of the maintenance hole 121 increases in the extending direction of the maintenance hole 121 toward the drain pan 2.

From this, because the internal diameter of the inboard of maintenance hole 121 is big for the internal diameter of outside for dredging tool 3 makes dredging tool 3 can have certain swing range like the elongated thing stretches into maintenance hole 121 back, thereby finely tunes dredging tool 3's orientation, makes dredging tool 3 can accurately reach wash port 121 department, reduces dredging tool 3 and wash port 21's the alignment degree of difficulty, thereby can reduce wash port 21's the clearance mediation degree of difficulty.

In some embodiments of the present invention, as shown in fig. 3 and 4, the maintenance hole 121 includes a through section 1211 and a diverging section 1212 connected to each other, the diverging section 1212 is adjacent to the inner side of the face frame 12 relative to the through section 1211, and the inner diameter of the through section 1211 is constant and the inner diameter of the diverging section 1212 is gradually increased in a direction from the outer side of the face frame 12 to the inner side of the face frame 12. That is, the diverging section 1212 is disposed adjacent to the drainage hole 21 relative to the straight section 1211, the straight section 1211 is located on the side of the diverging section 1212 away from the drainage hole 21, the end of the diverging section 1212 away from the drainage hole 21 is communicated with the end of the straight section 1211 adjacent to the diverging section 1212, the inner diameter of the end of the diverging section 1212 communicated with the straight section 1211 is the minimum, and the inner diameter of the end of the diverging section 1212 away from the straight section 1211 is the maximum.

From this for dredging tool 3 is back like the slender thing stretches into divergent section 1212, dredging tool 3 can have certain swing range, thereby finely tune dredging tool 3's orientation, makes dredging tool 3 can accurately stretch to wash port 121 department, reduces dredging tool 3 and wash port 21's the degree of difficulty of aiming at, thereby can reduce wash port 21's the clearance mediation degree of difficulty. Secondly, while ensuring a certain swing amplitude of the dredging tool 3, the maintenance hole 121 is an opening with a smaller inner diameter when viewed from the outside of the face frame 12 by providing the through section 1211 with a smaller inner diameter.

Optionally, the inner diameter of the through section 1211 ranges from 6.5 to 8.5 mm. That is, the inner diameter of the through section 1211 may be set to be between 6.5 and 8.5mm, for example, the inner diameter of the through section 1211 may be set to be 7mm, the inner diameter of the through section 1211 may be set to be 8mm, and the like, which is not particularly limited herein. Thereby, the amplitude of the oscillation of the pull through 3 is controlled while it is ensured that the pull through 3 can have a certain amplitude of oscillation within the through section 1211.

Specifically, in the related art, the diameter of the screwdriver used by the serviceman is about 6.5 mm. That is, the maintenance person may directly insert the maintenance hole 121 using a screwdriver to dredge the drainage hole 21. Therefore, when the maintenance personnel dredge the drain hole 21, the maintenance personnel do not need to prepare an additional dredging tool 3, and only need to use a screwdriver as the dredging tool 3, so that the maintenance personnel can clean and dredge the drain hole 21 more conveniently.

In addition, because the internal structure of the indoor unit 100 is compact, by setting the inner diameter of the through section 1211 to be not more than 8.5mm, the risk that the dredging tool 3 has a large swing amplitude in the maintenance hole 121 and collides with the inside of the indoor unit 100, such as a heat exchanger component or a fan component, due to the large inner diameter of the through section 1211 can be well avoided, and thus the safety of the maintenance process of the drain hole 21 is ensured.

Optionally, the length of the diverging section 1212 is not less than the length of the through section 1211. The length here refers to the extension length of the divergent section 1212 or the straight section 1211 on the face frame 12 in the direction from the outer side to the inner side of the face frame 12. That is, in the direction from the outer side to the inner side of the face frame 12, the extending length of the divergent section 1212 is longer than the length of the through section 1211, or the extending length of the through section 1211 is equal to the extending direction of the divergent section 1212.

Therefore, the swing amplitude of the dredging tool 3 can be increased well, the flexibility of orientation adjustment of the dredging tool 3 is improved, the alignment difficulty of the dredging tool 3 and the drain hole 21 is further reduced, and the cleaning and dredging difficulty of the drain hole 21 can be reduced.

In some embodiments of the present invention, the inner diameter of the maintenance hole 121 gradually increases in a direction from the outside of the face frame 12 to the inside of the face frame 12. The outer side of the face frame 12 refers to the side of the face frame 12 away from the water-receiving tray 2, and the inner side of the face frame 12 refers to the side of the face frame 12 close to the water-receiving tray 2. That is to say, the maintenance hole 121 extends from the side of the face frame 12 away from the water collector 2 to the side of the face frame 12 close to the water collector 2, the inner diameter of the end of the maintenance hole 121 away from the water collector 2 is the smallest, and the inner diameter of the end of the maintenance hole 121 close to the water collector 2 is the largest.

Therefore, while ensuring that the dredging tool 3 has a certain swing amplitude, the inner diameter of one end of the maintenance hole 121 far away from the water pan 2 is set to be minimum, so that the maintenance hole 121 is an opening with a smaller inner diameter when being observed from the outer side of the face frame 12. Secondly, the difficulty of opening the maintenance hole 121 is reduced, and the production efficiency of the indoor unit 100 of the air conditioner is improved.

In some embodiments of the utility model, the service hole 121 is disposed coaxially with the drainage hole 21. That is, the axis of the maintenance hole 121 is collinear with the axis of the drain hole 21. Specifically, when the cleaning dredging of the drain hole 21 is required, the dredging tool 3 is inserted into the maintenance hole 121, and the dredging tool 3 is pushed to move toward the drain hole 21. Because the maintenance hole 121 and the drain hole 21 are coaxially arranged, when the dredging tool 3 moves towards the direction close to the drain hole 21 along the maintenance hole 121, one end of the dredging tool 3 close to the drain hole 21 can be directly inserted into the drain hole 21, that is, the dredging tool 3 does not need to be aligned with the drain hole 21, so that the maintenance steps of the drain hole 21 can be simplified, the maintenance difficulty of the drain hole 21 is reduced, and the cleaning and dredging efficiency of the drain hole 21 is improved.

In some embodiments of the utility model, the service hole 121 is disposed higher than the drain hole 21. The higher here means that the height of the maintenance hole 121 is higher than the height of the drainage hole 21 in the vertical direction. It will be appreciated that, in order to ensure the drainage of the drip pan 2, the drainage hole 21 is usually formed in the bottom plate 11 of the drip pan 2, that is, the drainage hole 21 is not higher than the bottom of the drip pan 2 in the vertical direction, so that the peripheral wall of the drip pan 2 is higher than the drainage hole 21. From this, through being higher than the wash port 21 setting with maintenance hole 121, can avoid better keeping out being sheltered from by the perisporium of water collector 2 between maintenance hole 121 and the wash port 21, when guaranteeing that wash port 21 can the drainage of water collector 2 bottom, guarantee through maintenance hole 121 can directly observe or dredge wash port 21, rationally distributed, can reduce the degree of difficulty of observing wash port 21 or dredging wash port 21 betterly.

In one specific example, the water pan 2 is disposed on the bottom plate 11, the drain hole 21 is disposed at the lowest position of the bottom wall of the bottom plate 11, and the drain hole 21 extends obliquely upward in a direction toward the face frame 12. Wherein, the water collector 2 can be integrated with the chassis 11, namely a part of the chassis 11 forms the water collector 2, thereby saving the assembly process of the water collector 2 and the chassis 11 better and ensuring the firm connection of the water collector 2 and the chassis 11.

It should be noted that the swing amplitude of the dredging tool 4 in the maintenance hole 121 and the inclination angle of the drainage hole 21 can be flexibly set according to actual conditions, so as to ensure that the swing adjustment of the dredging tool 4 in the maintenance hole 121 can be aligned with the drainage hole 21, and no specific limitation is made here.

In some embodiments of the present invention, as shown in fig. 8 to 10, the indoor unit 100 further includes: a closing member 4 for opening and closing the maintenance hole 121. The opening of the maintenance hole 121 means that the blocking member 4 does not block the maintenance hole 121 and the drainage hole 21 can be observed or dredged through the maintenance hole 121, and the closing of the maintenance hole 121 means that the blocking member 4 blocks the maintenance hole 121, for example, the blocking member 4 can be filled in the maintenance hole 121, and the drainage hole 21 cannot be observed or dredged through the maintenance hole 121.

Specifically, when the indoor unit 100 of the air conditioner is in a normal operation state, the panel is in a closed state, and the blocking member 4 closes the maintenance hole 121 (as shown in fig. 13), so that dirt such as dust is blocked from entering the installation space 13 or the water pan 2 through the maintenance hole 121, the blockage of the drain hole 21 caused by the accumulation of the dust can be avoided, the cleanness and sanitation inside the indoor unit 100 of the air conditioner can be kept, and a healthy and safe breathing environment can be created for a user.

When the heat exchanger component or the fan component needs to be maintained, the panel is switched from the closed state to the open state, the blocking piece 4 keeps closing the maintenance hole 121, and the maintenance hole 121 is prevented from being visually observed from the outer side of the face frame 12. When maintenance of the drain hole 21 is required, the panel is switched to an open state, and then the plugging piece 4 is operated to open the maintenance hole 121, so that a user or a maintenance person can directly observe or dredge the drain hole 21 through the maintenance hole 121, and the face frame 12 does not need to be detached, and maintenance difficulty of the drain hole 21 is low. After the maintenance of the drain hole 21 is completed, the maintenance hole 121 is closed using the block 4, and the panel is switched to the closed state.

In some embodiments of the present invention, the blocking member 4 is detachably provided on the face frame 12, and at least a portion of the blocking member 4 is accommodated in the maintenance hole 121 when the blocking member 4 closes the maintenance hole 121. When the blocking member 4 closes the maintenance hole 121, a part of the blocking member 4 may be accommodated in the maintenance hole 121, or the entire blocking member 4 may be accommodated in the maintenance hole 121, which is not limited herein. Therefore, the maintenance hole 121 can be better blocked by the blocking piece 4 positioned in the maintenance hole 121, dirt such as dust can be blocked to enter the water receiving tray 2 through the maintenance hole 121 to be butted, and the maintenance hole 121 can be prevented from being visually observed from the outer side of the face frame 12. In addition, when the maintenance hole 121 needs to be opened, the plugging member 4 is detached from the face frame 12, and the operation is simple.

Therefore, when the plugging piece 4 opens the maintenance hole 121, the plugging piece 4 is kept connected with the face frame 12, so that the risk that the plugging piece 4 drops after opening the maintenance hole 121 can be well avoided.

In some embodiments of the present invention, as shown in fig. 10 to 12, the blocking piece 4 includes a main body portion 42 and a cap 41, the main body portion 42 is adapted to be received in the maintenance hole 121, the cap 41 is located on the outer side of the face frame 12, a part of the projection of the cap 41 on the reference plane is located outside the projection of the maintenance hole 121 on the reference plane, and the reference plane is perpendicular to the central axis of the maintenance hole 121. That is, when the closing member 4 closes the maintenance hole 121, the main body portion 42 is positioned inside the maintenance hole 121 to close the maintenance hole 121, and a part of the cap 41 is positioned outside the maintenance hole 121 in the radial direction of the maintenance hole 121. Therefore, by arranging the part of the cap 41 outside the maintenance hole 121, the cap 41 can be better blocked from entering the maintenance hole 121, so that the situation that the plugging piece 4 is completely accommodated in the maintenance hole 121 and is inconvenient to detach when being installed can be better avoided.

Further, the outer peripheral edge portion of the cap 41 is disposed apart from the face frame 12. That is, a certain gap is provided between the side wall of the outer peripheral edge portion of the cap 41 close to the body portion 42 and the outer side wall of the face frame 12, and the outer side wall of the face frame 12 refers to the side of the face frame 12 away from the water pan 2. Therefore, a user or a maintenance person can stretch a tool or a hand into a gap between the peripheral edge part of the cap 41 and the face frame 12, so that the cap 41 is tilted towards a direction away from the face frame 12, the main body part 42 is driven to be separated from the maintenance hole 121, the maintenance hole 121 is opened to observe or dredge the drainage hole 21, and the difficulty in disassembling the plugging piece 4 is reduced.

In some embodiments of the utility model, the block piece 4 is formed with an auxiliary groove for assisting in the removal of the block piece 4; or an auxiliary space 43 for assisting the removal of the block piece 4 is defined between the block piece 4 and the outer side wall of the face frame 12. Therefore, a user or a maintenance person can detach the plugging member 4 from the face frame 12 by using a tool or a hand through the auxiliary groove or the auxiliary space 43 to open the maintenance hole 121 to observe or dredge the drainage hole 21, and the detachment difficulty of the plugging member 4 is reduced.
