[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0037] The utility model proposes an air conditioner indoor unit 100 for an air conditioner. The air conditioner includes an air conditioner outdoor unit 200 and an air conditioner indoor unit 100, and a flexible connection assembly 300 connects the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 respectively. The air conditioner can be a split air conditioner that is convenient for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit 100 and the outdoor heat exchanger of the air conditioner outdoor unit 200, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 respectively, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the utility model can also be an ordinary split air conditioner or an integrated air conditioner.

[0038] See also Figures 1 to 6 In one embodiment of the utility model, an air-conditioning indoor unit 100 includes a casing 1, a water pump 2, a first drain pipe 3 and a second drain pipe 4, and a drain groove 12 is provided in the casing 1; the water pump 2 is arranged in the casing 1, and the water pump 2 has a water inlet end and a water outlet end, and the water inlet end is connected to the drain groove 12; one end of the first drain pipe 3 is connected to the water outlet end, and the other end is connected to the external space of the casing 1; one end of the second drain pipe 4 is connected to the water outlet end, and the other end is connected to the air-conditioning outdoor unit 200.

[0039] Specifically, the drainage trough 12 is used to collect and store the condensed water generated by the indoor heat exchanger in the air-conditioning indoor unit 100, and the water pump 2 is used to extract the condensed water in the drainage trough 12, so the water inlet end of the water pump 2 is connected to the drainage trough 12, one end of the second drainage pipe 4 is connected to the water outlet end, and the other end is connected to the air-conditioning outdoor unit 200. In the prior art, the condensed water generated by the indoor heat exchanger is stored in the drainage trough 12 and then discharged to the air-conditioning outdoor unit 200 through the second drainage pipe 4 to cool the outdoor heat exchanger. However, this method often makes it difficult to ensure that the condensed water is discharged from the air-conditioning outdoor unit 200 in time. For example, when the air conditioner is working for a long time, the condensed water may leak, which may cause the air-conditioning outdoor unit 200 to drip accidentally. In some application scenarios of split air conditioners, when the air-conditioning indoor unit 100 and the air-conditioning outdoor unit 200 are both placed on the indoor floor for operation, the condensed water will wet the floor. Therefore, a first drain pipe 3 is provided, one end of which is connected to the water outlet, and the other end is connected to the external space of the casing 1, that is, the first drain pipe 3 is directly connected to the external space of the air conditioner without passing through the air conditioner outdoor unit 200, so as to directly discharge the condensed water of the air conditioner indoor unit 100 to the outside, and the first drain pipe 3 can be extended and bent arbitrarily, so as to realize the discharge of the condensed water to any position of the external space, or to recover the condensed water through another container, so as to facilitate the discharge of the condensed water. Moreover, the length and bending shape of the first drain pipe 3 can be arranged according to the actual installation scene, so that the extension path and bending angle of the first drain pipe 3 can be adjusted, so as to facilitate the user to arrange the first drain pipe 3 according to their own needs, so as to facilitate the drainage of the indoor unit of the air conditioner.

[0040] For a split-type air conditioner, if the user needs to move the air conditioner midway, it is often necessary to drain the condensed water from the air conditioner indoor unit 100 in advance. At this time, the condensed water in the drain trough 12 can be directly pumped out using the water pump 2 and the first drain pipe 3, further facilitating the discharge of the condensed water. The water outlet ends are connected simultaneously through the first drain pipe 3 and the second drain pipe 4, respectively, and the proportion of condensed water pumped into the first drain pipe 3 and the second drain pipe 4 by the water pump 2 can be reasonably allocated, thereby facilitating the discharge of the condensed water and reducing the possibility of accidental water seepage in the air conditioner outdoor unit 200.

[0041] Among them, the water pump 2 can be arranged inside the casing 1 or outside the casing 1. If the water pump 2 is arranged outside the casing 1, it is helpful to realize the miniaturization of the air conditioner. At this time, the water inlet end of the water pump 2 is connected to the drain groove 12 through a pipeline, and the first drain pipe 3 and the second drain pipe 4 are correspondingly arranged outside the casing 1; if the water pump 2 is arranged inside the casing 1, it is helpful to move the air conditioner. At this time, the water inlet end of the water pump 2 can be connected to the drain groove 12 through a pipeline, or it can be directly arranged in the drain groove 12, and the corresponding part of the first drain pipe 3 and / or the second drain pipe 4 is arranged in the casing 1, and the other part passes through the casing 1 to communicate with the external space or the air conditioner outdoor unit 200. It should be noted that the outdoor space is any space other than the air conditioner. The first drain pipe 3 can be directly connected to the water outlet end, or it can be indirectly connected to the water outlet end, such as through a pipeline. The second drain pipe 4 can be directly connected to the water outlet end, or it can be indirectly connected to the water outlet end, such as through a pipeline.

[0042] In an embodiment of the utility model, the flexible connection assembly 300 includes a sleeve and a flexible refrigerant pipe arranged in the sleeve, one end of the second drain pipe 4 is connected to the water outlet, and the other end is inserted into the sleeve to connect to the air conditioner outdoor unit 200. Specifically, for a split air conditioner, the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 need to be connected through a flexible refrigerant pipe and an electric wire. In order to conveniently discharge the condensed water generated by the air conditioner indoor unit 100 into the room, the second drain pipe 4 is usually introduced into the air conditioner outdoor unit 200 together with the flexible refrigerant pipe and the electric wire, thereby facilitating the connection between the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 and facilitating the secondary use of the condensed water. Therefore, one end of the second drain pipe 4 is connected to the water outlet, and the other end is inserted into the sleeve.

[0043] In other embodiments, the flexible connection assembly 300 includes a flexible refrigerant pipe, an energized wire, and a sleeve sleeved on the flexible refrigerant pipe and the energized wire. One end of the second drain pipe 4 is connected to the water outlet, and the other end is passed through the sleeve to connect to the air conditioner outdoor unit 200.

[0044] See also Figure 1 In the embodiment of the utility model, a first drain valve 31 or a first drain plug is provided at the other end of the first drain pipe 3. Specifically, the first drain valve 31 or the first drain plug is provided at one end of the first drain pipe 3 away from the water pump 2, so as to control the opening or closing of the first drain pipe 3, thereby facilitating the user to select the discharge method of the condensed water of the air conditioner indoor unit 100, and facilitating the user's use.

[0045] In another embodiment of the present invention, a first drain valve 31 or a first drain plug may also be provided on the second drain pipe 4, thereby further facilitating the user to select a discharge method for condensed water of the air-conditioning indoor unit 100, thereby facilitating user use.

[0046] In order to facilitate the connection between the first drain pipe 3, the second drain pipe 4 and the water outlet, in the embodiment of the utility model, the first drain pipe 3 includes a main drain section 32 and a sub-drain section 33, one end of the main drain section 32 is connected to the water outlet, and the sub-drain section 33 and the second drain pipe 4 are both connected to the other end of the main drain section 32. Specifically, the main drain section 32 is used to simultaneously connect the sub-drain section 33 and the second drain pipe 4, that is, the first drain pipe 3 and the second drain pipe 4 share a part of the pipe section. Compared with the first drain pipe 3 and the second drain pipe 4 being connected to the water outlet separately, this solution not only facilitates the connection between the first drain pipe 3, the second drain pipe 4 and the water outlet, but also saves part of the pipe section, thereby helping to reduce the occupied space of the air conditioner indoor unit 100 and helping to miniaturize the air conditioner indoor unit 100.

[0047] Therefore, the main drainage section 32 is generally arranged inside the casing 1, and the branch drainage section 33 is at least partially located outside the casing 1. The length and bending shape of the branch drainage section 33 can be arranged according to the actual installation scenario.

[0048] In another embodiment of the utility model, the second drain pipe 4 includes a main drain section 32 and a branch drain section 33, one end of the main drain section 32 is connected to the water outlet, and the branch drain section 33 and the first drain pipe 3 are both connected to the other end of the main drain section 32.

[0049] In another embodiment of the utility model, the water outlet includes a first water outlet and a second water outlet, one end of the first drain pipe 3 is connected to the first water outlet, and the other end is connected to the external space of the casing 1, one end of the second drain pipe 4 is connected to the first water outlet, and the other end is connected to the air conditioner outdoor unit 200.

[0050] To further facilitate the installation of the first drain pipe 3 and the second drain pipe 4, in the embodiment of the present utility model, please refer to Figure 1 and Figure 2 The sub-drainage section 33 and the second drain pipe 4 are connected to the main drain section 32 through the three-way joint 34, so as to facilitate the connection between the sub-drainage section 33, the second drain pipe 4 and the main drain section 32. In this embodiment, the second drain pipe 4 extends upward to the top of the air conditioner indoor unit 100 and then passes through the casing 1, so the height of the three-way joint 34 should be located between the drain groove 12 and the top of the air conditioner indoor unit 100, that is, the three-way joint 34 is located in the casing 1.

[0051] See also Figure 1 , Figure 4 and Figure 5In the embodiment of the utility model, the housing 1 includes a chassis 11, the drain trough 12 and the water pump 2 are both arranged on the chassis 11, and the chassis 11 is provided with a plurality of stoppers 13, and the plurality of stoppers 13 fix a portion of the first drain pipe 3 to the chassis 11. Specifically, since the drain trough 12 is used to collect and store condensed water, the drain trough 12 is at least partially arranged below the indoor heat exchanger, so the housing 1 includes the chassis 11, the drain trough 12 is arranged on the chassis 11, and the water pump 2 is also arranged on the chassis 11, so as to facilitate the absorption of the condensed water in the drain trough 12. In order to realize the miniaturization of the air conditioner indoor unit 100, the water pump 2 can be installed using the remaining space on the chassis 11. Correspondingly, at least a portion of the main drainage section 32 of the first drain pipe 3 is fixed on the chassis 11 and extends on the chassis 11. Therefore, a plurality of limit members 13 are provided on the chassis 11. The plurality of limit members 13 are arranged at intervals along the extension direction of the main drainage section 32, thereby fixing the main drainage section 32 to the chassis 11 and reducing the possibility of accidental movement of the main drainage section 32.

[0052] Further, in the embodiments of the present invention, please refer to Figure 4 and Figure 5 The plurality of limiting members 13 include a first limiting member 14, on which a limiting groove is provided, and the first drain pipe 3 is clamped in the limiting groove. Specifically, the first limiting member 14 can be configured as a support baffle provided on the chassis 11, and the limiting groove is provided on the support baffle, so that the first drain pipe 3 can be fixed and the installation of the first drain pipe 3 is convenient; the first limiting member 14 can also be configured as two supporting parts provided on the chassis 11, and the two supporting parts and the chassis 11 are enclosed together to form the limiting groove.

[0053] In another embodiment of the present invention, please refer to Figure 4 , the plurality of stoppers 13 include a second stopper 15, and the second stopper 15 presses the first drain pipe 3 against the chassis 11. Specifically, since the first drain pipe 3 is arranged on the chassis 11, in order to ensure that the first drain pipe 3 is installed in close contact with the chassis 11 and reduce the height installation space of the first drain pipe 3, the chassis 11 is provided with a plurality of second stoppers 15 arranged at intervals, and the second stopper 15 presses the first drain pipe 3 against the chassis 11, thereby ensuring the fixation of the first drain pipe 3.

[0054] In yet another embodiment of the present invention, please refer to Figure 5, the plurality of limiting members 13 include a plurality of third limiting members 16 disposed at intervals, and two adjacent third limiting members 16 are disposed at an angle to jointly form a limiting channel for the first drain pipe 3 to pass through. Specifically, when the first drain pipe 3 extends to the edge of the chassis 11, in order to facilitate the first drain pipe 3 to bend and extend upward, the plurality of third limiting members 16 are disposed at intervals, and two adjacent third limiting members 16 are disposed at an angle, so that the plurality of third limiting members 16 are alternately staggered, thereby forming a limiting channel, and further ensuring the fixation of the first drain pipe 3.

[0055] To facilitate the setting of pump 2, please refer to Figure 1 and Figure 3 In the embodiment of the utility model, an indoor heat exchanger is also provided in the housing 1, and the drainage groove 12 includes a first drainage area 121 and a second drainage area 122 which are connected to each other. The first drainage area 121 is correspondingly arranged below the indoor heat exchanger, and the second drainage area 122 is located on one side of the indoor heat exchanger. The water pump 2 is arranged in the second drainage area 122. Specifically, the first drainage area 121 is arranged below the indoor heat exchanger, and is mainly used to receive the condensed water generated by the indoor heat exchanger. The second drainage area 122 is connected to the first drainage area 121, and the water pump 2 is arranged in the second drainage area 122, so as to absorb the water in the drainage groove 12. In order to facilitate the water pump 2 to absorb the water in the drainage groove 12, the height of the second drainage area 122 is less than or equal to the height of the first drainage area 121, so as to reduce the possibility of condensed water accumulating in the first drainage area 121 and improve the absorption rate of the water pump 2 to the first drainage area 121.

[0056] The second drainage area 122 is located on one side of the indoor heat exchanger, that is, at any position except below the indoor heat exchanger, so as to facilitate the installation of the water pump 2 and help to utilize other spaces of the air conditioner indoor unit 100. Therefore, the first drainage area 121 and the second drainage area 122 can be arranged at intervals, and the two are connected through the drainage channel 123.

[0057] Furthermore, the first drainage area 121 is provided with a drainage hole 124 connected to the outside of the housing 1, and the drainage hole 124 is located on the side of the first drainage area 121 facing the side of the housing 1. That is, the drainage hole 124 is located on the side of the housing 1. Since the drainage groove 12 is mainly used to receive the condensed water generated by the indoor heat exchanger, the first drainage area 121 is located below the indoor heat exchanger. If the drainage hole 124 is correspondingly located in the first drainage area 121, it is helpful to reduce the water flow path and facilitate the condensed water to be discharged from the drainage hole 124. Moreover, the drainage hole 124 is located on the side of the first drainage area 121 facing the side of the housing 1, which is convenient for the condensed water to be discharged smoothly from the drainage hole 124 compared to being located below the first drainage area 121 (the bottom of the first drainage area 121 is the bottom of the housing 1, which often does not have enough installation space, resulting in poor drainage at the drainage hole 124).

[0058] See also Figure 1 and Figure 3 In the embodiment of the utility model, the drain groove 12 is provided with a drain hole 124 connected to the outside of the housing 1, and the drain hole 124 is provided with a second drain valve or a second drain plug 17. Specifically, the drain hole 124 is directly connected to the outside of the housing 1, so that the condensed water in the drain groove 12 can be directly discharged. When the amount of condensed water in the drain groove 12 is small, it can be directly discharged through the drain hole 124 without starting the water pump 2. However, this drainage method often requires tilting the air conditioner indoor unit 100 at a certain angle, which is inconvenient to operate. The drain hole 124 is provided with a second drain valve or a second drain plug 17 to control the conduction of the drain hole 124, so that the user can choose the discharge method of the condensed water of the air conditioner indoor unit 100.

[0059] The utility model also proposes an air conditioner, which includes an air-conditioning indoor unit 100. The specific structure of the air-conditioning indoor unit 100 refers to the above-mentioned embodiment. Since the air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0060] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
