Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an embedded type air-conditioning indoor unit. Background Art

[0002] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners consist of a vapor compression refrigeration cycle system consisting of an evaporator, condenser, compressor, throttling device, and other necessary components. The air conditioner outputs cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0003] The embedded air conditioner indoor unit is a new type of air conditioner indoor unit, which is used for embedded installation. For example, it is embedded in the kitchen cabinet, cabinets in other rooms or other chamber structures. After the cabinet door is opened, the air inlet and outlet on the front side of the embedded air conditioner indoor unit are exposed for air intake and exhaust.

[0004] However, in some households, the size of the cabinets for embedded air conditioners is limited, and the size of embedded air conditioners cannot be uniformly designed to be larger, so it is difficult to integrate the fresh air function. In addition, the air conditioning efficiency of the embedded embedded air conditioner indoor unit is always low, and no good solution can be found. Utility Model Content

[0005] The purpose of the utility model is to provide a built-in air-conditioning indoor unit which overcomes the above problems or at least partially solves the above problems.

[0006] The utility model aims to solve the problem that the size of the embedded air conditioner cannot be uniformly designed to be large and it is difficult to integrate the fresh air function.

[0010] A fresh air module is used to introduce outdoor fresh air into the indoor environment. The fresh air module includes a shell, and the shell is provided with at least one second connection part. Each second connection part is detachably connected to one first connection part to achieve a detachable connection between the fresh air module and the indoor unit body.

[0011] Optionally, each of the first connecting portions is a snap-on hole; and

[0012] Each of the second connecting parts is a buckle, and the buckle is buckled in the buckle hole.

[0013] Optionally, each of the second connecting parts comprises:

[0014] A first section extending from a surface of the housing; and

[0015] The second section extends downward from the end of the first section away from the housing.

[0016] Optionally, the fresh air module is arranged at a lateral side end of the indoor unit body; and

[0017] The number of the first connecting parts is two and they are arranged in the up-down direction.

[0018] Optionally, the housing is provided with a fresh air outlet; and

[0019] The fresh air module also includes a fresh air fan and a fresh air inlet pipe, one end of the fresh air inlet pipe is connected to the outdoor environment, and the other end is connected to the shell. The fresh air fan is used to force outdoor fresh air to enter the shell through the fresh air inlet pipe and then blow out through the fresh air outlet.

[0020] Optionally, an air inlet for air intake is provided on the first side surface of the housing, and the air inlet and the air outlet are arranged side by side;

[0021] The embedded air conditioner indoor unit further includes a first panel movably mounted on the housing; and

[0022] The first panel has a closed position for closing the air inlet, and has an open position between the air inlet and the air outlet, so that in the open position, the air inlet is allowed to take in air, and the incoming airflow of the air inlet is isolated from the outgoing airflow of the air outlet to avoid mixing of the incoming airflow and the outgoing airflow.

[0023] Optionally, the first side of the first panel is rotatably mounted on the housing; and

[0024] The first side is adjacent to a side of the air inlet that is adjacent to the air outlet, so that when the first panel is in the open position, the first side is located between the air inlet and the air outlet.

[0025] Optionally, the air inlet is located above the air outlet; and

[0026] The first side is a bottom side of the first panel.

[0027] Optionally, the embedded air conditioner indoor unit further includes:

[0028] At least one drive device, each of the drive devices comprising:

[0029] A driving motor, fixedly installed inside the housing; and

[0030] A connecting rod, a first end of which is fixedly connected to the rotating shaft of the driving motor, and a second end of which is slidably mounted on the first panel;

[0031] When the driving motor drives the connecting rod to swing back and forth, the second end of the connecting rod moves toward or away from the air outlet, thereby driving the first panel to close or open the air inlet.

[0033] A roller is installed at the second end of each connecting rod, and the roller can be slidably inserted into the slide groove, so that when the connecting rod swings, the second end of the connecting rod slides along the length direction of the slide groove, thereby driving the first panel to close or open the air inlet.

[0034] The embedded air conditioner indoor unit of the utility model includes an indoor unit body and a fresh air module. The fresh air module is detachably connected to the indoor unit body. When the cabinet used to install the embedded air conditioner indoor unit is large enough, the fresh air module can be installed to enable the embedded air conditioner indoor unit to have a fresh air function. When the size of the cabinet used to install the embedded air conditioner indoor unit is limited, the fresh air module can be installed without installing it. As can be seen from the above, the embedded air conditioner indoor unit of the utility model allows users to choose whether to integrate the fresh air function, and the usage scenarios are more diverse.

[0035] Furthermore, the inventor of the utility model discovered through research that the reason why the existing embedded air-conditioning indoor unit has low air conditioning efficiency is related to the air intake method of the embedded air-conditioning indoor unit. The embedded air-conditioning indoor unit adopts the front airflow form, and the air inlet and the air outlet are arranged adjacent to each other and are very close. This causes a part of the outlet air flow to mix with the inlet air flow and flow back into the casing from the air inlet. Taking the cooling mode as an example, the temperature of these outlet air flows is relatively low in itself, and their mixing with the inlet air flow will cause the overall temperature of the inlet air flow to become lower, lowering the heat exchange rate between the inlet air flow and the heat exchanger, causing the heat exchanger to be unable to fully exert its heat exchange capacity, reducing its heat exchange efficiency, and further causing the air conditioning efficiency to decrease.

[0036] The embedded air conditioner indoor unit of the utility model is specially designed with a first panel, which has a closed position for closing the air inlet, and an open position between the air inlet and the air outlet. In the open position, the first panel opens the air inlet to allow air to enter the air inlet, and isolates the air inlet airflow of the air inlet from the air outlet airflow of the air outlet to avoid mixing of the air inlet airflow and the air outlet airflow, and to avoid mixing of the heat exchange airflow into the air inlet airflow, thereby ensuring the heat exchange efficiency of the heat exchanger and improving the energy efficiency of the air conditioner. In the closed position, the first panel closes the air inlet, which can prevent external dust and impurities from entering the interior of the casing through the air inlet, making the interior of the casing cleaner.

[0037] Furthermore, the embedded air conditioner indoor unit of the utility model also includes a windshield, which is rotatably mounted on the housing to open and close the air outlet and guide the flow direction of the outlet airflow. When the windshield is in a position to close the air outlet, it is located between the air inlet and the air outlet, thereby separating the air inlet airflow from the air inlet and the air outlet airflow, preventing the heat exchange airflow from mixing with the air inlet airflow, ensuring the heat exchange efficiency of the heat exchanger, and thus improving the energy efficiency of the air conditioner.

[0056] The embodiment of the utility model provides a built-in air-conditioning indoor unit.

[0057] The indoor unit of the built-in air conditioner is the indoor part of the split air conditioner or the indoor terminal model of the central air conditioner, which is used to adjust the indoor air, specifically, including adjusting the temperature, humidity, air quality of the air, humidifying, dehumidifying the indoor air, introducing fresh air, etc. The air conditioner can form a vapor compression refrigeration cycle system with an evaporator, condenser, compressor, throttling device and other necessary components to output cold air / hot air through the fan to achieve cooling and heating of the indoor environment.

[0058] Figure 1 It is a structural schematic diagram of an embedded air conditioner indoor unit according to an embodiment of the utility model; Figure 2 yes Figure 1 The structural schematic diagram of the indoor unit body 100 in the embedded type air conditioner indoor unit is shown; Figure 3 yes Figure 1 A schematic structural diagram of a fresh air module 300 in an embedded air-conditioning indoor unit is shown.

[0059] like Figures 1 to 3 As shown, the embedded air-conditioning indoor unit of the embodiment of the utility model may generally include an indoor unit body 100 and a fresh air module 300.

[0060] The embedded air conditioner indoor unit is embedded, and is used to be embedded in a preset chamber. The air inlet 11 and the air outlet 12 face the opening of the chamber to exchange air with the external space of the chamber. The chamber can be a chamber of a cabinet. The cabinet may include a cabinet body and a cabinet door, the cabinet body defines a chamber and has an opening, and the cabinet door is movably arranged on the cabinet body to open and close the opening.

[0061] The indoor unit body 100 has a housing 10, and the housing 10 is provided with an air outlet 12. The indoor unit body 100 is used to output a heat exchange airflow to the indoor environment through the air outlet 12 to adjust the indoor environment air. The housing 10 is used to accommodate the main components of the embedded air conditioner indoor unit, including a fan, an indoor heat exchanger, an electric control module, etc. The housing 10 is used to be embedded in a cabinet or other structure with a chamber, and its front side is exposed to the outside. This embodiment does not limit the shape of the housing 10. Figure 1 The case 10 is shown as a horizontally long strip. In addition, the case 10 can also be an upright column, square or other shapes. The case 10 has a top plate constituting its top structure and a front plate constituting its front structure. The top plate and the front plate face upward and forward respectively. The case 10 is provided with at least one first connecting portion 16.

[0062] The fresh air module 300 is used to introduce outdoor fresh air into the indoor environment. The fresh air module 300 includes a shell 310. The shell 310 is provided with at least one second connection part 350. Each second connection part 350 is detachably connected to a first connection part 16 to achieve a detachable connection between the fresh air module 300 and the indoor unit body 100.

[0063] The embedded air conditioner indoor unit of the embodiment of the utility model comprises an indoor unit body 100 and a fresh air module 300. The fresh air module 300 is detachably connected to the indoor unit body 100. When the cabinet used to install the embedded air conditioner indoor unit is large enough, the fresh air module 300 can be installed to enable the embedded air conditioner indoor unit to have a fresh air function. When the size of the cabinet used to install the embedded air conditioner indoor unit is limited, the fresh air module 300 can be selected not to be installed. As can be seen from the above, the embedded air conditioner indoor unit of the utility model allows users to choose whether to integrate the fresh air function, and the usage scenarios are more abundant.

[0064] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, each first connection portion 16 is a snap-fit ​​hole. Each second connection portion 350 is a snap-fit, which is snap-fitted to the snap-fit ​​hole. Figure 3 As shown, each second connection part 350 may include a first section 351 and a second section 352, wherein the first section 351 extends from the surface of the housing 310, and the second section 352 extends downward from the end of the first section 351 away from the housing 310. That is, the second connection part 350 is "L" shaped, so that when the operator removes the fresh air module 300, he only needs to lift the fresh air module 300 upward to separate the second connection part 350 from the first connection part 16, which is very convenient. In other embodiments, the first connection part 16 may be a buckle, and the second connection part 350 may be a snap-on hole.

[0065] In some embodiments of the present invention, Figure 1 As shown, the fresh air module 300 is disposed at the lateral side of the indoor unit body 100, that is, the left end or the right end of the indoor unit body 100. Figure 2 As shown, there are two first connection parts 16 arranged in the up-down direction to make the clamping more stable.

[0066] In some embodiments of the present invention, Figure 3 As shown, the housing 310 is provided with a fresh air outlet 311. The fresh air module 300 further includes a fresh air blower 330 and a fresh air inlet pipe 320, one end of the fresh air inlet pipe 320 is connected to the outdoor environment, and the other end is connected to the housing 310, and the fresh air blower 330 is used to promote outdoor fresh air to enter the housing 310 through the fresh air inlet pipe 320, and then blow out through the fresh air outlet 311.

[0067] Figure 4 It is a structural schematic diagram of an indoor unit body 100 of an embedded type air conditioner indoor unit according to an embodiment of the utility model; Figure 5 yes Figure 4 The indoor unit body 100 is shown as a schematic diagram of a state when the first panel 20 is in an open position; Figure 6 yes Figure 5 Schematic side view of the indoor unit body 100 is shown.

[0068] like Figures 4 to 6 As shown, the embedded air conditioner indoor unit of the embodiment of the utility model further includes a first panel 20. An air inlet 11 for air intake is provided on the first side surface of the casing 10, and the air inlet 11 and the air outlet 12 are arranged side by side.

[0069] The first panel 20 is movably mounted on the housing 10. The first panel 20 has a closed position for closing the air inlet 11, such as Figure 4 , and has an open position between the air inlet 11 and the air outlet 12, such as Figure 5 Thus, when in the open position, the air inlet 11 is allowed to enter, and the air inlet flow of the air inlet 11 is isolated from the air outlet flow of the air outlet 12 to prevent the air inlet flow from mixing with the air outlet flow.

[0070] like Figures 4 to 6 As shown, the aforementioned first side surface is the front surface. Of course, in other embodiments, the aforementioned first side surface may also be a lateral side surface, a lower surface or an upper surface, which is not limited in the embodiments of the present utility model.

[0071] The fan is disposed in the housing 10 to force the air outside the housing 10 to enter the housing 10 through the air inlet 11 to form an air inlet airflow. The embodiment of the utility model does not limit the form of the fan. The fan can be various forms such as cross-flow type, axial flow type, centrifugal type, etc.

[0072] The indoor heat exchanger is arranged in the housing 10, and is used to exchange heat with the incoming air flow in the housing 10 to form a heat exchange air flow. When the air conditioner operates in a cooling mode, the heat exchange air flow is a cold air flow. When the air conditioner operates in a heating mode, the heat exchange air flow is a hot air flow. Of course, the air conditioner can have only a cooling function, or have both cooling and heating functions.

[0073] The indoor heat exchanger, the throttling device, the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the outdoor unit of the air conditioner are connected through pipelines to form a vapor compression refrigeration cycle system. The compressor is usually a rolling rotor compressor. The throttling device may include a capillary tube and an electronic expansion valve. For heat pump air conditioners, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between cooling mode and heating mode.

[0074] For heat pump air conditioners, in cooling mode, the indoor heat exchanger acts as an evaporator, and in heating mode, the indoor heat exchanger acts as a condenser.

[0075] An air duct is formed inside the housing 10, and the outlet of the air duct is connected to the air outlet 12, so as to allow the heat exchange air in the housing 10 to be blown out of the housing 10 through the air outlet 12. Under the action of the fan, the indoor air enters the housing 10 through the air inlet 11, and after completing the forced convection heat exchange with the indoor heat exchanger, forms a heat exchange airflow, which is guided by the air duct 15 and blown from the air outlet 12 to the indoor environment.

[0076] The inventor of the embodiment of the utility model has found through research that the reason why the existing embedded air conditioner indoor unit has low air conditioning efficiency is related to the air intake method of the embedded air conditioner indoor unit. The embedded air conditioner indoor unit adopts the front airflow form, and the air inlet 11 and the air outlet 12 are arranged adjacent to each other and the distance is very close. This causes a part of the outlet air flow to mix with the inlet air flow and flow back from the air inlet 11 into the housing 10.

[0077] Taking the cooling mode as an example, the temperature of these outlet air flows is relatively low in itself. When the outlet air flows into the inlet air flow, the overall temperature of the inlet air flow will become lower, which will reduce the heat exchange rate between the inlet air flow and the heat exchanger, causing the heat exchanger to be unable to fully utilize its existing heat exchange capacity, thereby reducing its heat exchange efficiency, and further causing the air conditioner's functional energy efficiency to decrease.

[0078] In order to solve this technical problem, the embedded air conditioner indoor unit of the embodiment of the utility model is specially designed with a first panel 20, which has a closed position for closing the air inlet 11, and has an open position between the air inlet 11 and the air outlet 12. In the open position, the first panel 20 opens the air inlet 11 to allow air to enter the air inlet 11, and isolates the air inlet airflow of the air inlet 11 from the air outlet airflow of the air outlet 12 to avoid mixing of the air inlet airflow and the air outlet airflow, and to avoid mixing of the heat exchange airflow into the air inlet airflow, thereby ensuring the heat exchange efficiency of the heat exchanger and improving the energy efficiency of the air conditioner. In the closed position, the first panel 20 closes the air inlet 11, which can prevent dust and impurities from entering the interior of the casing 10 through the air inlet 11, so that the cleanliness of the interior of the casing 10 is better.

[0079] Furthermore, the embedded air conditioner indoor unit of the embodiment of the utility model can also adjust the air intake volume of the air inlet 11 by adjusting the opening of the first panel 20, thereby achieving adjustable air intake volume.

[0080] In some embodiments of the present invention, the first side 201 of the first panel 20 is rotatably mounted on the housing 10. Furthermore, the first side 201 is adjacent to a side of the air inlet 11 adjacent to the air outlet 12, so that when the first panel 20 is in the open position, the first side 201 is located between the air inlet 11 and the air outlet 12, and is closer to the housing 10, so as to more thoroughly isolate the inlet airflow and the outlet airflow.

[0081] Preferably, reference Figure 5 and Figure 6 , the air inlet 11 can be located above the air outlet 12, and the first side 201 is the bottom side of the first panel 20. The bottom side is adjacent to the top side of the air outlet 12.

[0082] The top edge 202 of the first panel 20 is a free end. In this way, the first panel 20 as a whole rotates around the first edge 201. In this way, when the air conditioner is running in cooling mode, the indoor hot air with relatively low density can be more suspended above the room, and it is easier to enter the housing 10 from the air inlet 11 located higher.

[0083] Further, the first panel 20 is configured so that when it is in the open position, the angle a between it and the first side surface is between 20° and 60°, that is, 20°≤a≤60°, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°. Preferably, 30°≤a≤50°.

[0084] When a is designed to be too large, it will occupy too much space. When a is designed to be too small, it will easily affect the air intake, thereby affecting the operating capacity of the air conditioner. The embodiment of the utility model reasonably limits the range of a, so as to minimize the impact on the air intake of the air conditioner.

[0085] The embodiment of the utility model enables the first panel 20 to be rotatably arranged, and its installation structure is simpler, the cost is lower, and the reliability is stronger.

[0086] Of course, in other embodiments of the present invention, the first panel 20 can be installed on the housing 10 in a translational manner, or installed on the housing 10 in a planar motion manner, and the planar motion is a composite motion of translational motion and rotation. Those skilled in the art can reasonably design the motion mode and motion path of the first panel 20, which will not be described in detail here.

[0087] Figure 7 yes Figure 6 A magnified image of point A; Figure 8 Figure 4 The indoor unit body 100 is a schematic structural diagram after the first panel 20 is removed.

[0088] In some embodiments of the present invention, Figures 6 to 8 As shown, the embedded air conditioner indoor unit further includes at least one driving device 40, each driving device 40 is installed between the casing 10 and the first panel 20, and is used to controllably drive the first panel 20 to move between an open position and a closed position.

[0089] The driving device 40 can be connected to the controller of the air conditioner to be controlled by the controller. When the air conditioner is turned on, the controller can control the driving device 40 to operate and drive the first panel 20 from the closed position to the open position. When the air conditioner is turned off, the controller can control the driving device 40 to operate and drive the first panel 20 from the open position to the closed position.

[0090] The number of the driving device 40 may be one or more.

[0091] For example, for Figures 4 to 8 The long strip-shaped first panel 20 shown can be provided with two driving devices 40 , so that the two driving devices 40 are respectively connected to the two lateral ends of the first panel 20 , and the two driving devices 40 move synchronously.

[0092] Specifically, in some embodiments of the present invention, Figures 6 to 8 As shown, each driving device 40 includes a driving motor 41 and a connecting rod 42 .

[0093] The driving motor 41 is fixedly installed inside the housing 10. The first end of the connecting rod 42 is fixedly connected to the rotating shaft of the driving motor 41, and the second end is slidably installed on the first panel 20. In this way, the connecting rod 42 and the first panel 20 constitute a crank slider mechanism. When the driving motor 41 drives the connecting rod 42 to swing back and forth, the second end of the connecting rod 42 moves toward or away from the air outlet 12, thereby driving the first panel 20 to close or open the air inlet 11.

[0094] like Figure 8 As shown, the first side panel of the housing 10 may be provided with a clearance groove 13 , the driving motor 41 is located inside the housing 10 , and the connecting rod 42 extends to the outside of the housing 10 through the clearance groove 13 .

[0095] The driving motor 41 is preferably a stepping motor capable of controlled forward and reverse rotation, so as to facilitate fine adjustment of the rotation angle of the first panel 20 .

[0096] Specifically, Figure 6 and Figure 7 As shown, the inner side of the first panel 20 facing the air inlet 11 has at least one slide groove 210. A roller 43 is installed at the second end of each connecting rod 42, and the roller 43 is slidably inserted into the slide groove 210, so that when the connecting rod 42 swings, the second end of the connecting rod 42 slides along the length direction of the slide groove 210, thereby driving the first panel 20 to close or open the air inlet 11.

[0097] like Figure 7 As shown, the inner side of the first panel 20 may be provided with a long strip 21, which is spaced apart from the inner side of the first panel 20, and the space between the long strip 21 and the first panel 20 forms a slide groove 210. Both ends of the long strip 21 are bent toward the first panel 20 to be connected to the first panel 20.

[0098] Furthermore, the long board 21 and the first panel 20 may be formed as an integral piece to reduce the cost.

[0099] In some embodiments, each roller 43 can be rotatably mounted on the second end of the connecting rod 42, so that when the driving motor 41 drives the first panel 20 to rotate, the roller 43 rolls in the slide groove 210, and its movement is smoother and less noisy.

[0100] Of course, in other embodiments, the roller 43 may be fixedly connected to the second end of the connecting rod 42 , and when the driving motor 41 drives the first panel 20 to rotate, the roller 43 slides in the sliding groove 210 .

[0101] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the embedded air conditioner indoor unit also includes a wind shield 50.

[0102] The wind shield 50 is rotatably mounted on the housing 10 to open and close the air outlet 12 and guide the flow direction of the airflow. When the wind shield 50 is in a position to close the air outlet 12, it is located between the air inlet 11 and the air outlet 12, thereby separating the airflow of the air inlet 11 from the airflow of the air outlet 12.

[0103] When the wind shield 50 is in the position of closing the air outlet 12, as shown in FIG. Figure 5 , which is located between the air inlet 11 and the air outlet 12, so as to better separate the inlet airflow of the air inlet 11 from the outlet airflow of the air outlet 12, avoid the heat exchange airflow from mixing with the inlet airflow, ensure the heat exchange efficiency of the heat exchanger, and thus improve the energy efficiency of the air conditioner.

[0104] For example Figure 5 As shown, the air outlet 12 and the air inlet 11 are opened at the front side of the housing 10, and the air outlet 12 is located below the air inlet 11. The wind shield 50 can be rotatably installed on the housing 10 around a transverse axis so as to be rotated to a wind shielding position extending forward from the upper side of the air outlet 12, thereby separating the inlet air flow from the heat exchange air flow to prevent the outlet air flow from mixing with the inlet air flow, as shown in FIG. Figure 5 .

[0105] like Figure 5 As shown, the wind shield 50 can be extended horizontally when in the wind shielding position. The wind shield 50 can also have a position to close the air outlet 12, such as Figure 4 .like Figure 5 As shown, the rotation axis of the wind deflector 50 can be located at its end, and adjacent to the upper edge of the air outlet 12, so as to rotate between the closed position and the windproof position. In addition, the wind outlet angle and the air volume of the air outlet 12 can also be adjusted by adjusting the rotation angle of the wind deflector 50.

[0106] Furthermore, the embedded air conditioner indoor unit further comprises a guide plate, the end of which is rotatably mounted on the housing 10, and the rotation axis of which extends transversely and is close to the lower side of the air outlet 12, so as to adjust the air outlet direction of the air outlet 12. In this way, the wind shield 50 and the guide plate form a "double-open" mode, and the two can adjust the air outlet direction and air volume together or independently.

[0107] In some embodiments, Figure 8 As shown, at least one filter 18 may be provided at the air inlet 11, and each filter 18 is used to filter the air entering the housing 10 through the air inlet 11 to remove dust and impurities therein.
