Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to an air conditioner. Background Technology

[0002] If a user accidentally touches the high-speed fan of an air conditioner while it is running, it can cause personal injury.

[0003] Some wall-mounted air conditioners have protective nets at their air outlets to protect the fan and prevent users from touching it. However, current protective nets are either fixed to the air outlet with screws or with additional plastic parts attached to both ends of a wire mesh. These two methods are not only inefficient to assemble but also require additional parts. If these additional parts become loose, the protective net will be unstable, and finding matching parts is difficult, leading to higher costs.

[0004] Another part is fixed to the body by clips. The clip structure is complicated and the ease of assembly still needs to be improved. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an air conditioner that makes the installation and removal of the protective net's clips very convenient and reduces maintenance costs.

[0006] An air conditioner according to an embodiment of this application includes: a main body. The main body includes: a housing, the interior of which is formed a cavity, and a heat exchange air inlet and a heat exchange air outlet formed on the housing, the heat exchange air outlet being a protective air outlet; and a base disposed within the cavity, on which a volute air duct is formed.

[0007] The air conditioner also includes a heat exchange fan, which is disposed within the volute air duct.

[0008] The air conditioner also includes a protective net, which is installed at the protective air vent.

[0009] The main body has a positioning hole on one side of the protective air vent and a first buckle on the other side. The protective net has a positioning post on one side and a second buckle on the other side. The positioning post is inserted into the positioning hole, and the second buckle engages with the first buckle.

[0010] The first buckle includes two limiting ribs, and a limiting groove and a flared opening are formed between the two limiting ribs in sequence. The width of the flared opening gradually increases in the direction away from the limiting groove, and it is the inlet and outlet opening of the limiting groove.

[0011] The second latching part includes a retaining rib, which is located within the limiting groove.

[0012] According to the air conditioner embodiment of this application, the protective net is pre-positioned on one side by utilizing the cooperation of the positioning hole and the positioning post. Then, the entire protective net is rotated around the positioning hole to reach the snap-fit ​​position, making positioning simple. In particular, the flared design allows the retaining rib to easily snap into the wider flared opening after rotating with the protective net, facilitating insertion and reducing the chance of misinstallation. The limiting groove formed by two limiting ribs, with its rib structure, makes the limiting ribs easily deformable under force, thus reducing the chance of jamming when inserting them into the limiting groove from the flared opening. Therefore, the overall assembly of the protective net is very convenient.

[0013] In some embodiments, the first latching portion further includes a positioning block, the positioning block being located on the side of the limiting groove away from the positioning hole, and the locking rib abutting against the positioning block.

[0014] Specifically, the end of the retaining rib is formed into a hook, and the retaining rib abuts against the positioning block through the hook.

[0015] In some embodiments, the second latching portion further includes a positioning rib, which connects to the latching rib and abuts against the side of the limiting rib facing the positioning hole.

[0016] Specifically, the positioning rib extends along the arrangement direction of the two limiting ribs, and the positioning rib abuts against the two limiting ribs.

[0017] In some embodiments, a throat is formed between the two limiting ribs, and the width of the throat is smaller than the width of the retaining rib.

[0018] In some embodiments, the base forms an air duct outlet at one end of the volute air duct, the air duct outlet is disposed toward the heat exchange air outlet, and the positioning hole and the first snap-fit ​​portion are formed on the base and located on both sides of the air duct outlet.

[0019] Specifically, a support rib is formed on the base, and the support rib and the first buckle part are arranged sequentially along the edge of the air duct outlet, and the housing overlaps the support rib.

[0020] Furthermore, the surface of the supporting rib facing the air duct outlet is the first supporting surface, and the housing overlaps on the first supporting surface;

[0021] The distance between the limiting rib and the air duct outlet is greater than the distance between the first support surface and the air duct outlet;

[0022] The second latching part is located on the side of the first support surface away from the air duct outlet.

[0023] Furthermore, the housing is provided with a clearance notch to avoid the retaining rib.

[0024] Optionally, the supporting ribs and the limiting ribs are spaced apart;

[0025] The end of the supporting rib facing the limiting rib forms a step, and the step has a second supporting surface for supporting the second buckle portion. The distance between the second supporting surface and the air duct outlet is greater than the distance between the first supporting surface and the air duct outlet.

[0051] Some embodiments of this application provide an air conditioner 10000.

[0052] Typically, an air conditioner 10000 is a split-type air conditioner, which includes an indoor unit and an outdoor unit. The indoor and outdoor units are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0053] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling device. The compressor, outdoor heat exchanger, throttling device, and indoor heat exchanger form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers. Some air conditioners can operate in a cooling mode, while others can also operate in a heating mode.

[0054] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0055] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner 10000, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner 10000, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0056] In some embodiments, the outdoor heat exchanger may include heat exchange fins to increase the contact area between outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0057] The outdoor fan is configured to draw in outside air into the outdoor unit and expel the outdoor air, which has been heated by the outdoor heat exchanger, to the outside. The outdoor fan provides power for the flow of outdoor air.

[0058] A throttling device connects the outdoor and indoor heat exchangers. It regulates the refrigerant pressure flowing through both devices, thereby controlling the refrigerant flow rate between them. The flow rate and pressure of the refrigerant between the outdoor and indoor heat exchangers affect their heat exchange performance. The throttling device can be a throttling tube, an electronic valve, etc. When the throttling device is an electronic valve, its opening is adjustable to regulate the refrigerant flow rate and pressure.

[0059] In some designs, the air conditioner 10000 may include a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 10000 can perform a cooling mode or a heating mode.

[0060] An indoor heat exchanger is configured to exchange heat between indoor air and a refrigerant transported within the indoor heat exchanger. In some embodiments, the indoor heat exchanger may include heat exchange fins to increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0061] The heat exchange fan is configured to draw indoor air into the indoor unit and deliver the indoor air, after heat exchange with the indoor heat exchanger, into the room, providing power for the flow of indoor air.

[0062] Air conditioner 10000 may include a control device, which is mainly used to control the operating frequency of the compressor and the opening degree of the throttling device. Some control devices can also control the speed of the outdoor fan and the speed of the heat exchange fan. The control device is connected to the compressor, the throttling device, the motor driving the outdoor fan, and the common motor 42 driving the heat exchange fan via a data cable to transmit communication information.

[0063] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC), and may be configured to perform the corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device.

[0064] Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), card, stick, or keyboard drive).

[0065] Currently, the air conditioner 10000 is equipped with a heat exchange air inlet 101 and a heat exchange air outlet 102, which inevitably leads to people accidentally sticking their fingers into them, causing personal injury. In order to solve the above problem, some embodiments of this application provide an air conditioner 10000 that is equipped with a protective net 5 at the dangerous air outlet to avoid personal injury.

[0066] Here, air conditioner 10000 is an indoor unit. Optionally, air conditioner 10000 is a wall-mounted air conditioner, which is typically installed on a wall, for example, in the upper area of ​​an indoor wall. Of course, this application does not exclude the possibility that in some embodiments, air conditioner 10000 may be a cabinet air conditioner or a portable air conditioner, etc.

[0067] The air conditioner 10000 according to an embodiment of this application is described in detail below with reference to the accompanying drawings.

[0068] Reference Figures 1-3 According to an embodiment of this application, the air conditioner 10000 includes a main body 1000, which includes a housing 1. A cavity V1 is formed inside the housing 1, and a heat exchange air inlet 101 and a heat exchange air outlet 102 are formed on the housing 1. The housing 1 can play a protective role and constitutes the overall external structure of the air conditioner 10000.

[0069] Typically, the casing 1 is a long, rectangular shell. When the air conditioner 10000 is a wall-mounted air conditioner, the length of the casing 1 is set horizontally, that is, the casing 1 is installed on the wall laterally. In actual products, in order to drain condensate, in some embodiments the casing 1 is installed on the wall laterally, and at a small angle to the horizontal plane.

[0070] The main body 1000 also includes an indoor heat exchanger (not shown in the figure), which is disposed within the accommodating cavity V1. As described above, the indoor heat exchanger is a loop in the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger to cool or heat the air flowing through its surface. In the air conditioner 10000, the indoor heat exchanger typically extends along the length of the casing 1. For example, the indoor heat exchanger is a two-fold or three-fold heat exchanger, with each fold being a plate-like structure extending along the length.

[0071] Reference Figure 3 and Figure 4The main body 1000 also includes a base 3, which is located within the accommodating cavity V1. The base 3 is an internal mounting support structure of the main body 1000, and the indoor heat exchanger can be mounted on the base 3. For example, a volute air duct V03 is formed on the base 3. After the indoor air enters the casing 1, the flow direction is guided by the volute air duct V03, ensuring that the indoor air encounters less resistance when flowing through the indoor heat exchanger.

[0072] The wall-mounted air conditioner 10000 also includes a heat exchange fan, which is installed inside the volute air duct V03. When the heat exchange fan rotates, it allows the air inside the air conditioner to exchange heat with the indoor space.

[0073] In some embodiments, the heat exchange fan is, for example, a cross-flow fan, which has low noise and large air volume. The air velocity of the cross-flow fan is more evenly distributed along its axial direction, which is beneficial for increasing the air delivery distance and range. Moreover, when a cross-flow fan is used and is arranged along the length of the heat exchange fan, it is beneficial for the driven airflow to flow through the entire indoor heat exchanger, ensuring the balance of heat exchange efficiency across all parts of the indoor heat exchanger.

[0074] By providing a heat exchange outlet 102 and a heat exchange inlet 101 in the casing 1, indoor air can be drawn into the casing 1 through the heat exchange inlet 101 when the heat exchange fan is running. After the indoor air exchanges heat with the indoor heat exchanger, the heat-exchanged air is sent back into the room through the heat exchange outlet 102.

[0075] Therefore, the indoor ambient temperature can be regulated. The indoor heat exchanger can be used as an evaporator to provide cooling airflow to the indoor space through the heat exchange outlet 102, or the indoor heat exchanger can be used as a condenser to provide heating airflow to the indoor space through the heat exchange outlet 102.

[0076] In some embodiments, the heat exchange outlet 102 is a protective air outlet. (Refer to...) Figure 3 and Figure 4 The air conditioner 10000 also includes a protective net 5, which is located at the protective air vent. This effectively prevents the user from touching the heat exchange fan through the protective air vent. The protective net 5 can be installed on the casing 1 or on the base 3.

[0077] Reference Figure 3 and Figure 4 The main body 1000 has a positioning hole 130 on one side of the protective air vent and a first buckle part 140 on the other side. The protective net 5 has a positioning post 51 on one side and a second buckle part 52 on the other side. The positioning post 51 is inserted into the positioning hole 130, and the second buckle part 52 is engaged with the first buckle part 140.

[0078] The first latching part 140 includes two limiting ribs 141, with a limiting groove 142 and a flared opening 144 formed sequentially between the two limiting ribs 141. The flared opening 144 gradually increases in width in the direction away from the limiting groove 142 and serves as the inlet and outlet opening for the limiting groove 142. The second latching part 52 includes a locking rib 521, which is located within the limiting groove 142.

[0079] When assembling the protective net 5, the positioning post 51 on one side of the protective net 5 can be inserted into the positioning hole 130 of the main body 1000 first. Then, the entire protective net 5 can be rotated around the positioning hole 130 until it reaches the first snap-fit ​​part 140. At this point, simply insert the snap-fit ​​521 from the flared opening 144 into the limiting groove 142 to complete the snap-fit ​​connection between the second snap-fit ​​part 52 and the first snap-fit ​​part 140. The snap-fit ​​action is smooth and the operation is simple.

[0080] This snap-fit ​​assembly method eliminates the need for additional screws and plastic parts, saving on the number of components and avoiding the risk of parts falling off or the protective net 5 shaking during use, thus making the protective net 5 more stable and durable. Moreover, the reduced number of components lowers the cost and makes maintenance easier.

[0081] By utilizing the cooperation between the positioning hole 130 and the positioning post 51, the protective net 5 is pre-positioned on this side. Then, the entire protective net 5 is rotated around the positioning hole 130 to reach the snap-fit ​​position, making positioning simple. In particular, the design of the flared opening 144 allows the retaining rib 521 to easily snap into the wider flared opening 144 after rotating with the protective net 5, facilitating insertion and reducing the chance of misinstallation. The two limiting ribs 141 form a limiting groove 142. The rib structure makes the limiting ribs 141 easily deformable under stress, thus reducing the chance of jamming when inserting them into the limiting groove 142 from the flared opening 144. Therefore, the overall assembly of the protective net 5 is very convenient.

[0082] Specifically, two limiting ribs 141 are spaced apart laterally along the main body 1000, and a retaining rib 521 is inserted between the two limiting ribs 141. The two limiting ribs 141 restrict the retaining rib 521 laterally, thereby restricting the protective net 5 laterally.

[0083] Optionally, the two limiting ribs 141 are symmetrically arranged, for example in Figure 6 and Figure 8 The two limiting ribs 141 are symmetrical about the left and right, with a simple shape and easy processing. Alternatively, the two limiting ribs 141 can be Y-shaped.

[0084] In some embodiments, such as Figures 5-9As shown, a throat 143 is formed between the two limiting ribs 141, and the width of the throat 143 is smaller than the width of the retaining rib 521. This arrangement prevents the retaining rib 521 from coming out of the limiting groove 142 from the throat 143. The limiting rib 141 can restrict the retaining rib 521 at this location, thereby preventing the entire protective net 5 from loosening.

[0085] Specifically, on the two limiting ribs 141, at the throat 143, protrusions are formed that extend toward each other, and the throat 143 is formed between the two protrusions.

[0086] Since the throat 143 is restricted by two limiting ribs 141, when the retaining rib 521 moves to the throat 143, only a slight force is needed to deform the limiting ribs 141, and the retaining rib 521 can be moved into the limiting groove 142. Afterwards, the limiting ribs 141 return to their original shape, thus restricting the retaining rib 521 within the limiting groove 142.

[0087] To prevent the protective net 5 from coming loose in the other direction, further restrictive structures are also provided in this application.

[0088] In some specific embodiments, such as Figure 6 As shown, the first latching part 140 also includes a positioning block 145, which is located on the side of the limiting groove 142 away from the positioning hole 130, and the locking rib 521 abuts against the positioning block 145. In this way, the protective net 5 is locked and limited by the two limiting ribs 141 in one direction, and in the other direction, the protective net 5 is locked and limited by the positioning hole 130 and the positioning block 145, so the protective net 5 is actually limited in both directions.

[0089] Specifically, the end of the retaining rib 521 forms a hook 522, and the retaining rib 521 abuts against the positioning block 145 through the hook 522. In this way, the hook 522 can increase the contact area with the positioning block 145 and improve the stability of the stop. Moreover, setting the end of the retaining rib 521 with a hook can improve the safety when the protective net 5 is removed.

[0090] Optionally, the retaining rib 521 and the hook 522 are L-shaped.

[0091] In other specific embodiments, such as Figure 8 As shown, the second latching part 52 further includes a positioning rib 523, which connects to the locking rib 521 and abuts against the side of the limiting rib 141 facing the positioning hole 130. In this way, the protective net 5 is latched and limited by the two limiting ribs 141 in one direction, and in the other direction, the protective net 5 is latched and limited by the positioning hole 130 and the limiting rib 141, thus effectively limiting the protective net 5 in both directions.

[0092] Specifically, the positioning rib 523 extends along the arrangement direction of the two limiting ribs 141, and the positioning rib 523 abuts against the two limiting ribs 141. In this way, the two limiting ribs 141 simultaneously support the positioning rib 523, making the positioning more reliable and preventing inaccurate positioning due to skewing.

[0093] Optionally, the retaining rib 521 and the positioning rib 523 are arranged in a cross shape.

[0094] In some embodiments, the protective net 5 includes multiple horizontal ribs and multiple vertical ribs. The positioning post 51 can be an extension of the vertical rib, and the clamping rib 521 can be another extension of the vertical rib. In this way, the overall structure of the protective net 5 is simple, easy to process, and has a low cost.

[0095] Specifically, both the horizontal and vertical ribs can be made of iron wire.

[0096] In some embodiments, such as Figure 3 and Figure 4 As shown, the base 3 forms an air duct outlet 301 at one end of the volute air duct V03. The air duct outlet 301 is positioned facing the heat exchange air outlet 102. The positioning hole 130 and the first snap-fit ​​part 140 are formed on the base 3 and are located on both sides of the air duct outlet 301. This allows the protective net 5 to be hidden inside the housing 1, improving the aesthetics.

[0097] Specifically, such as Figure 9 As shown, a support rib 32 is formed on the base 3. The support rib 32 and the first snap-fit ​​part 140 are arranged sequentially along the edge of the air duct outlet 301, and the housing 1 overlaps on the support rib 32. This arrangement allows one side of the first snap-fit ​​part 140 to be assembled with the housing 1 through the support rib 32, reducing air leakage gaps.

[0098] Specifically, the surface of the support rib 32 facing the air duct outlet 301 is the first support surface 321, and the housing 1 is attached to the first support surface 321.

[0099] The distance between the limiting rib 141 and the air duct outlet 301 is greater than the distance between the first support surface 321 and the air duct outlet 301. The second latching part 52 is located on the side of the first support surface 321 away from the air duct outlet 301.

[0100] by Figure 6 and Figure 8 For example, the first support surface 321 is the upper side of the limiting rib 141. The first support surface 321 is higher than the upper side of the second buckle part 52. The second buckle part 52 will not prevent the housing 1 from overlapping the first support surface 321.

[0101] Furthermore, the housing 1 is provided with a clearance notch 108 to avoid the retaining rib 521. It can be understood that the position of the clearance notch 108 corresponds to the position of the retaining rib 521, which is beneficial to use the housing 1 to seal the second snap part 52 and further reduce the air leakage gap.

[0102] Optionally, the side of the clearance notch 108 has a guide slope, so that when the housing 1 is assembled, the clearance notch 108 can be easily covered on the retaining rib 521. In this way, the retaining rib 521 is also confined within the clearance notch 108, that is, the housing 1 presses down the second buckle part 52, making the protective net 5 more secure.

[0103] In some specific embodiments, such as Figure 6 and Figure 8 As shown, the support ribs 32 and the limiting ribs 141 are spaced apart. The end of the support rib 32 facing the limiting rib 141 forms a step 33. The step 33 has a second support surface 331 for supporting the second latching part 52. The distance between the second support surface 331 and the air duct outlet 301 is greater than the distance between the first support surface 321 and the air duct outlet 301. In other words, the support ribs 32, by being spaced apart, avoid a certain amount of space to accommodate the second latching part 52 of various structures, reducing the probability of the second latching part 52 getting stuck at this location.

[0104] Among them, by setting a step 33, the step 33 has a second support surface 331. When the second buckle part 52 is provided with a positioning rib 523, the positioning rib 523 can abut against the second support surface 331, so as to prevent the positioning rib 523 from being skewed and improve the reliability of limiting the protective net 5.

[0105] In some specific embodiments, the base 3 is provided with a water receiving groove 34, the opening of which faces upward, and the bottom of the positioning hole 130 protrudes into the water receiving groove 34. This prevents damage to the base 3 caused by the thin wall thickness of the positioning hole 130. Thus, the positioning hole 130 can support the protective net 5 even when it is repeatedly disassembled and reassembled.

[0106] Specifically, the bottom of the positioning hole 130 protrudes from the bottom wall of the water receiving tank 34.

[0107] In some specific embodiments, the base 3 is provided with a water receiving groove 34, and a positioning hole 130 is integrally formed on the base 3. The axial direction of the positioning hole 130 is consistent with the depth direction of the water receiving groove 34. It can be understood that the depth direction of the water receiving groove 34 is consistent with the main demolding direction of the base 3. Therefore, aligning the axial direction of the positioning hole 130 with the depth direction of the water receiving groove 34 is also beneficial for the demolding of the positioning hole and for the manufacturing of the base 3.

[0108] Specifically, the positioning hole 130 is a round hole. Optionally, the opening of the positioning hole 130 has a guide bevel to facilitate the insertion of the positioning pin 51 into the positioning hole 130.

[0109] In some embodiments of this application, the air conditioner 10000 further includes a baffle plate, the left and right ends of which are pivotally connected to the housing 1. The baffle plate is rotatable relative to the housing 1. When the baffle plate is rotated to the open state, the heat exchange air outlet 102 is exposed, facilitating airflow from the heat exchange air outlet 102. When the baffle plate is rotated to the closed state, the heat exchange air outlet 102 is blocked, preventing debris, flying insects, etc., from entering the air conditioner 10000 when the air conditioner 10000 is not in operation.

[0110] Other components of the air conditioner 1000 according to the embodiments of the present utility model, such as the controller, are known in their structure and principle to those skilled in the art and will not be described in detail here.

[0111] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0112] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
