Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit of a duct type air conditioner and an air conditioner. Background Art

[0002] An air conditioner refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in the environment of a building or structure. A duct air conditioner is one type of air conditioner, and it mainly supplies air to the room through a duct.

[0003] Currently, duct air conditioners include two types: blowing air conditioners and sucking air conditioners. Among them, the sucking air conditioner generally includes two parts: an indoor unit and an outdoor unit. The indoor unit sucks air, and after the air exchanges heat through the indoor heat exchanger, it becomes cold air. The cold air then passes through the air duct composed of the indoor box body, the fan system located in the indoor box body, and the motor system located in the indoor box body, and then is discharged from the indoor air outlet. During this process, the fan system, the motor system located in the indoor box body, and the outer wall of the air duct in contact with the cold air may all generate condensed water.

[0004] Duct air conditioners are generally installed inside the ceiling. Therefore, if the drainage of the duct air conditioner is not smooth, the condensed water in its water receiving tray is likely to escape and drip onto the ceiling, polluting the ceiling. Moreover, for the sucking air conditioner, since the cold air passes through the entire indoor box body, condensed water is easily generated on the outer wall of the indoor box body and directly drips onto the ceiling, polluting the ceiling. Summary of the Utility Model

Specific Embodiments

[0050] The following further describes in detail the specific embodiments of the present application with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0051] In the description of the present application, it should be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. The terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0052] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "height", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. in the present application is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0053] In the description of the present application, it should be understood that the terms "first" and "second" in the present application are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0054] In the present application, the air conditioner performs a refrigeration cycle or a heating cycle through a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle and the heating cycle include a series of processes such as compression, condensation, expansion, and evaporation. By the endothermic or exothermic process of the refrigerant, cold or heat is provided to the indoor space to adjust the temperature of the indoor space.

[0055] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0056] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0057] The air conditioner of the present application includes an indoor unit of the air conditioner and an outdoor unit of the air conditioner. The outdoor unit of the air conditioner includes a part of the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes an indoor heat exchanger. The expansion valve can be provided in the indoor unit of the air conditioner or the outdoor unit of the air conditioner.

[0058] The indoor heat exchanger and the outdoor heat exchanger serve as condensers or evaporators. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the refrigeration mode.

[0059] The directions described in this document are based on the direction in which the user faces the air conditioner. Among them, the left and right sides are distinguished according to the direction in which the user faces the air conditioner. The side facing the user when the air conditioner is in use is defined as the front side, and the opposite side is defined as the rear side. The upper and lower sides are defined when the air conditioner is operating normally to distinguish between up and down.

[0060] The following refers to Figures 1 - 12 Describe the ducted air conditioner indoor unit (hereinafter referred to as the air conditioner indoor unit 110) of the embodiment of the present application. It includes a body 1. The outer contour of the body 1 is a cuboid structure. The body 1 is provided with an indoor air inlet 2 and an indoor air outlet 3. The indoor air inlet 2 and the indoor air outlet 3 are respectively arranged at both ends of the body 1 in its width direction (i.e., the front-rear direction). The indoor air outlet 3 conveys the cold air generated by the air conditioner indoor unit 110 to each area in the room through a connecting ventilation pipe. An installation opening 4 is provided on the lower side of the body 1 to facilitate the assembly of the air conditioner indoor unit 110 through the installation opening 4.

[0061] A fan 5 and an indoor heat exchanger 6 are arranged inside the body 1. Among them, the fan 5 is arranged at the indoor air outlet 3, and the indoor heat exchanger 6 is arranged at the indoor air inlet 2. In this way, through the operation of the fan 5, air is sucked into the interior of the body 1 from the indoor air inlet 2. Then, the air reaches the indoor heat exchanger 6, is heated or cooled by the indoor heat exchanger 6, and then the air is sucked into the fan 5 and sent out from the indoor air outlet 3.

[0062] Of course, in addition to the fan 5 and the indoor heat exchanger 6, a motor system, pipelines, etc. can also be arranged inside the body 1 to cooperate with the fan 5 and the indoor heat exchanger 6 to meet the components for the operation of the indoor unit. It can be understood that when the air conditioner indoor unit 110 operates for refrigeration, the air is sucked into the body 1 and then exchanges heat at the indoor heat exchanger 6 to form cold air. In this way, most of the component shells inside the body 1 are in contact with the cold air, and the outer shell of the body 1 itself is also continuously in contact with the cold air. Therefore, there is a possibility of condensation water generation both inside the body 1 and on the outer wall of the body 1.

[0063] Therefore, the air conditioner indoor unit 110 of this embodiment is also equipped with a first water receiving tray 7, and a first drain port 8 for draining water is provided on the first water receiving tray 7. The body 1 is arranged inside the first water receiving tray 7, and there is a first gap 9 between the outer side wall of the body 1 and the first water receiving tray 7. Moreover, the first water receiving tray 7 is connected to the lower side of the body 1 and covers the installation opening 4, so that the first water receiving tray 7 and the body 1 cooperate to form an air duct 10 for air flow.

[0064] It should be noted that the housing 1 is arranged in the first water receiving tray 7, and it is not required that the first water receiving tray 7 covers the entire outer wall of the housing 1. Considering that the indoor air inlet 2 and the indoor air outlet 3 are respectively arranged at both ends of the housing 1 in the front and rear directions, the arrangement height of the first water receiving tray 7 is preferably such that it does not affect the passage of air through the indoor air inlet 2 and the indoor air outlet 3.

[0065] By providing a first gap 9 between the outer side of the body 1 and the first water receiving tray 7, the edge of the first water receiving tray 7 will exceed the outer wall of the body 1. In this way, even if condensation water is attached to the outer wall of the body 1, the condensation water can only fall into the first water receiving tray 7 and will not fall on the ceiling.

[0066] Moreover, based on the fact that the first water receiving tray 7 is connected to the lower side of the body 1 and the mounting port 4 of the cover body 1, the first water receiving tray 7 and the body 1 will form an air duct 10 for air flow, so that the air sucked into the body 1 by the fan 5 cannot escape from the outside of the body 1. After the air enters the body 1 from the indoor air inlet 2, it will flow to the fan 5 through the indoor heat exchanger 6 under the constraints of the first water receiving tray 7 and the body 1 itself and under the suction of the fan 5, and then be discharged from the indoor air outlet 3 through the fan 5.

[0067] Of course, after the first water receiving tray 7 and the machine body 1 cooperate to form the air duct 10, the cold air generated by the indoor heat exchanger 6 will also contact the first water receiving tray 7. Therefore, the first water receiving tray 7 can be connected with a heat preservation member 11, such as a heat insulation sponge. The heat preservation member 11 is arranged on the outer side of the first water receiving tray 7 and wraps the first water receiving tray 7.

[0068] Compared with wrapping the heat insulation sponge on the outer side of the body 1, the air conditioner indoor unit 110 of this embodiment can use the first water receiving pan 7 to receive the condensation water generated by the outer wall of the body 1, based on the setting of the first water receiving pan 7. Therefore, the air conditioner indoor unit 110 of this embodiment can only set the insulation member 11 on the outer side of the first water receiving pan 7, so that the area of ​​the insulation member 11 can be reduced. Moreover, the position where the first water receiving pan 7 contacts the cold air is on the lower side of the body 1, so the position where the first water receiving pan 7 is easily affected by the cold and condensation water is generated will be at the bottom of the first water receiving pan 7. Generally speaking, after the air conditioner indoor unit 110 is installed on the ceiling of the user's home, the first water receiving pan 7 is installed on the ceiling, and the bottom of the first water receiving pan 7 is in contact with the ceiling. The insulation member 11 arranged at the bottom of the first water receiving pan 7 is not easy to be touched or damaged, and the condensation water generated by the first water receiving pan 7 is not easy to slide onto the ceiling of the user's home.

[0069] In order to ensure the tightness of the air duct 10 and avoid air leakage in the air duct 10, refer to Figures 5 - 6, as an example of this embodiment, a first folding portion 1a may be provided on the lower side of the body 1. The first folding portion 1a is arranged around the installation opening 4 and is parallel to the upper surface of the first water receiving tray 7. Moreover, the first folding portion 1a is connected to the upper surface of the first water receiving tray 7, and a seal 12 is provided between the first folding portion 1a and the first water receiving tray 7.

[0070] The first folding portion 1a can increase the contact area between the body 1 and the first water receiving tray 7. According to the cooperation requirements between the body 1 and the first water receiving tray 7, the first folding portion 1a can extend towards the inside of the body 1, or, as Figure 6 described, extend towards the outside of the body 1. Moreover, according to the specification parameters of the body 1, the first water receiving tray 7, the blower 5, etc., the first folding portion 1a can be configured with a corresponding width so that the contact area between the body 1 and the first water receiving tray 7 can meet the connection stability of the two. By providing a seal 12 between the first folding portion 1a and the first water receiving tray 7, the seal 12 can seal the connection position between the lower side of the body 1 and the first water receiving tray 7, ensuring the airtightness of the air duct 10. Of course, the seal 12 can also be selected as heat-insulating and heat-preserving sponge to facilitate meeting the requirements of the airtightness and heat preservation of the air duct 10.

[0071] Refer to Figures 2 - 11 , as an example of this embodiment, the first water receiving tray 7 includes a base portion 7a and a surrounding portion 7b. Among them, the base portion 7a is a flat plate structure. The base portion 7a is connected to the lower side of the body 1 and covers the installation opening 4, so that the upper surface of the base portion 7a forms the wall surface of the air duct 10. The surrounding portion 7b surrounds the periphery of the base portion 7a, and the surrounding portion 7b protrudes upwards from the upper surface of the base portion 7a. Moreover, the first drain port 8 is provided on the surrounding portion 7b.

[0072] It can be understood that the upper surface of the base portion 7a is both the wall surface of the air duct 10 and the end face for receiving condensed water. The outer wall of the body 1 divides the upper surface of the base portion 7a into an inner region and an outer region. Among them, the inner region forms the wall surface of the air duct 10, and the outer region is outside the outer wall of the body 1, so that the condensed water adhering to the outer wall of the body 1 can fall into this outer region and be received by the first water receiving tray 7.

[0073] Based on the foregoing design of the first water receiving tray 7, a first gap 9 will be formed between the body 1 and the surrounding portion 7b. Moreover, considering the space required for receiving condensed water and avoiding the volume of the first water receiving tray 7 being too large and occupying too much space, the length of the first gap 9 is L, and 10 ≤ L ≤ 15 mm.

[0074] It can be understood that the first gap 9 is only used to reflect the relative position where the edge of the first water receiving tray 7 extends beyond the outer wall of the body 1, and the distance between the outer wall of the body 1 and the first water receiving tray 7 does not necessarily meet the length limit of the first gap 9. For example, the corners on the outer side of the body 1 can be configured as chamfered structures or rounded structures, so that the distance between the corners and the first water receiving tray 7 is increased. At this time, the distance between the corners of the body 1 and the first water receiving tray 7 may be greater than 15 mm.

[0075] The indoor heat exchanger 6 is arranged inside the body 1 to exchange heat with the air entering the body 1. Generally speaking, condensed water is likely to adhere to the outer wall of the indoor heat exchanger 6. Therefore, referring to Figures 2 - 10 , as an example of this embodiment, a second water receiving tray 13 can be provided inside the body 1, the indoor heat exchanger 6 is arranged inside the second water receiving tray 13, and the second water receiving tray 13 is provided with a second drain port 14 for draining water, and the second drain port 14 is communicated to the outside of the body 1 through a pipeline. By providing the second water receiving tray 13, the condensed water adhering to the outer surface of the indoor heat exchanger 6 will be collected by the second water receiving tray 13 and discharged to the outside of the body 1 through the second drain port 14.

[0076] Similar to the first water receiving tray 7, the indoor heat exchanger 6 is arranged inside the second water receiving tray 13, and it is not required that the second water receiving tray 13 wraps the entire outer wall of the indoor heat exchanger 6. Considering that the indoor air inlet 2 and the indoor air outlet 3 are respectively arranged at both ends of the body 1 in the front-rear direction, the arrangement height of the second water receiving tray 13 is also preferably such that it does not affect the passage of air between the indoor air inlet 2 and the indoor air outlet 3.

[0077] Considering the possible risk of blockage of the second water receiving tray 13, resulting in the overflow of the condensed water generated by the indoor heat exchanger 6 into the air duct 10, referring to Figures 2 - 10 , as an example of this embodiment, the second water receiving tray 13 can be arranged adjacent to the indoor air inlet 2, and the top of the second water receiving tray 13 is communicated with the indoor air inlet 2. The second water receiving tray 13 has an overflow part 13a, and the overflow part 13a is close to the indoor air inlet 2; and, the indoor heat exchanger 6 is arranged adjacent to the overflow part 13a and has a second gap 15 with the overflow part 13a, so that the indoor heat exchanger 6 is arranged on the front side of the indoor air inlet 2.

[0078] In the case of blockage of the second water receiving tray 13, after the condensed water accumulates to a certain liquid level height in the second water receiving tray 13, it will reach the indoor air inlet 2. At this time, the condensed water in the second water receiving tray 13 can overflow to the outside of the body 1 through the indoor air inlet 2 and enter the first water receiving tray 7. In this way, even if the second water receiving tray 13 encounters blockage, the condensed water in the second water receiving tray 13 will not directly overflow to the ceiling of the user's home.

[0079] It is understandable that a second gap 15 is arranged between the indoor heat exchanger 6 and the overflow portion 13a, which can make there be a certain spacing distance between the indoor heat exchanger 6 and the overflow portion 13a. The internal space of the second water receiving tray 13 corresponding to this spacing distance can communicate with the indoor air inlet 2. In the case where the second water receiving tray 13 is blocked, the condensed water will flow in the second water receiving tray 13, enter the internal space corresponding to the second gap 15, and reach the indoor air inlet 2 through the second gap 15.

[0080] In the case where the indoor heat exchanger 6 is arranged on the front side of the indoor air inlet 2, in order to enable the indoor heat exchanger 6 to be connected and fixed to the machine body 1, refer to Figures 2 - 4 , as an example of this embodiment, the machine body 1 can be connected with a mounting member 16. The mounting member 16 is arranged at the indoor air inlet 2 and extends towards the inside of the machine body 1. The indoor heat exchanger 6 is connected to the mounting member 16 to achieve connection and fixation with the machine body 1. Moreover, there is an overflow channel 17 communicating with the second gap 15 between the mounting member 16 and the inner bottom wall of the second water receiving tray 13.

[0081] Generally speaking, the projection of the indoor heat exchanger 6 on the second water receiving tray 13 will be smaller than the internal space of the second water receiving tray 13 itself to ensure that the condensed water on the outer surface of the indoor heat exchanger 6 can all fall into the second water receiving tray 13. Therefore, the indoor heat exchanger 6 is generally separated from and does not contact the inner side wall of the second water receiving tray 13. In this way, the condensed water in the second water receiving tray 13 can also flow around the indoor heat exchanger 6, enabling the condensed water in the second water receiving tray 13 to flow towards the second drain port 14 and be discharged outside the machine body 1. And, in the case where the second water receiving tray 13 is blocked, the condensed water in the second water receiving tray 13 can also enter the space corresponding to the second gap 15 through the overflow channel 17 and reach the indoor air inlet 2 through the second gap 15.

[0082] Refer to Figures 2 - 12 , as an example of this embodiment, the indoor unit 110 of this air conditioner further includes a connecting member 18; the connecting member 18 is arranged between the outer side wall of the machine body 1 and the first water receiving tray 7 to connect and fix the first water receiving tray 7 to the machine body 1. Specifically, as an example of this embodiment, the connecting member 18 can include a first connecting portion 18a, a second connecting portion 18b, and a third connecting portion 18c, where

[0083] the first connecting portion 18a is attached to the inner side of the peripheral edge portion 7b of the first water receiving tray 7; the second connecting portion 18b is attached to the outer peripheral side of the machine body 1; the third connecting portion 18c is connected between the first connecting portion 18a and the second connecting portion 18b and has a gap with the first water receiving tray 7.

[0084] The first connection part 18a and the second connection part 18b can be connected and fixed to the first water receiving tray 7 and the machine body 1 by fasteners such as bolts and rivets. Generally speaking, there are multiple connection members 18, and the multiple connection members 18 are evenly arranged on the peripheral side of the machine body 1, so that the machine body 1 and the first water receiving tray 7 are tightly connected.
