Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner with a pre-installed connecting pipe, an embedded air conditioner and an indoor unit thereof. Background Art

[0002] With the development of science and technology, people's living standards have been continuously improved, and the ownership of air conditioners is increasing.

[0003] Currently, in the prior art, the installation process of a wall-mounted air conditioner is as follows: First, connect the connecting pipe of the air conditioner to the indoor unit, then one person lifts the indoor unit, and another person picks up the connecting pipe and passes the connecting pipe through a pre-set wall-piercing hole. Finally, hang the indoor unit on the wall. Such an installation method requires at least two people for installation, resulting in a waste of human resources. Moreover, as the types of air conditioners become more diverse, users also pay more attention to the aesthetics of household appliances such as air conditioners, and pay more attention to the fit or integration of household appliances such as air conditioners with the home decoration style. Furthermore, users will need to inlay the indoor unit of the air conditioner in the cabinet, and inlaid air conditioners have thus appeared on the market. However, during the installation of an inlaid air conditioner, one person needs to pass the connecting pipe that has been connected to the indoor unit out of the cabinet cavity of the cabinet to the outside of the cabinet. At this time, due to reasons such as the narrow space in the cabinet cavity, the other person who is holding the air conditioner needs to continuously change positions, angles, etc. as the angle at which the connecting pipe passes through the cabinet changes. After the connecting pipe passes through the cabinet, then pass the connecting pipe through the wall-piercing hole, and finally install the indoor unit into the cabinet. Such an entire inlaid process is cumbersome and complex, not only wasting human resources, but also resulting in a longer installation time and an increased installation difficulty. Even, due to the narrow space in the cabinet cavity and the overall long length of the indoor unit connected to the connecting pipe, it may cause the indoor unit to be unable to be inlaid into the cabinet.

[0067] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 andFigure 5 In this embodiment, the indoor unit of the embedded air conditioner is used to be installed in the cabinet cavity 810 of the cabinet 800. The cabinet 800 has a cabinet opening 820 opened forward, and the cabinet opening 820 communicates with the cabinet cavity 810. The indoor unit of the embedded air conditioner includes a housing 100 and an indoor heat exchanger 200.

[0068] A pipe passing opening 110 is provided on the rear side wall of the housing 100, and a pipe passing space 120 extending in the front-rear direction is provided in the housing 100. The pipe passing space 120 communicates with the front of the pipe passing opening 110.

[0069] The indoor heat exchanger 200 is arranged in the housing 100. The indoor heat exchanger 200 is connected with a connecting pipe 300. The connecting pipe 300 includes a connecting end 310 located in front of the pipe passing space 120. The pipe passing opening 110 and the pipe passing space 120 are used to allow the connection pipe 400 of the embedded air conditioner to pass through the housing 100 from the rear side forward to the connecting end 310. The connecting end 310 is used to connect the connection pipe 400. The housing 100 includes a front cover 130 located in front of the indoor heat exchanger 200 and the connecting end 310. The front cover 130 is used to allow the connecting end 310 to be exposed in front of the indoor unit when the front cover 130 is detached from the indoor unit.

[0070] For the indoor unit of the embedded air conditioner of the present utility model, since a pipe passing opening 110 is provided on the rear side wall of the housing 100, a pipe passing space 120 communicating with the front of the pipe passing opening 110 is provided in the housing 100, and the connecting end 310 of the connecting pipe 300 connecting the indoor heat exchanger 200 extends to the front of the pipe passing space 120, the pipe passing opening 110 and the pipe passing space 120 can allow the connection pipe 400 of the embedded air conditioner to pass through the housing 100 from the rear side forward to the connecting end 310 and be connected to the connecting end 310. Moreover, when the front cover 130 is detached from the indoor unit, the connecting end 310 can be exposed in front of the indoor unit.

[0071] Furthermore, during the installation process of the indoor unit of the embedded air conditioner of the present utility model, the installer can first pass one end of the connection pipe 400 through the wall hole, pass the other end of the connection pipe 400 into the cabinet cavity 810 of the cabinet 800, then place the indoor unit into the cabinet cavity 810, pass the connection pipe 400 through the pipe passing opening 110 and the pipe passing space 120 from the rear side of the housing 100 forward, then open the front cover 130 to connect the connection pipe 400 and the connecting pipe 300, and finally fix the indoor unit in the cabinet cavity 810, or after passing the connection pipe 400 through the pipe passing opening 110 and the pipe passing space 120, first fix the indoor unit in the cabinet cavity 810, and finally open the front cover 130 to connect the connection pipe 400 and the connecting pipe 300. The entire installation process can be completed by only one person.

[0072] Therefore, the utility model can reduce the number of installers required for the installation of the indoor unit of the embedded air conditioner, save human resources, and reduce the installation cost. At the same time, the installation process of the indoor unit of the embedded air conditioner can be simplified, and the installation time and installation difficulty can be reduced.

[0073] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in this embodiment, the pipe passing space 120 and the connecting pipe 300 are located at the same end in the length direction of the indoor heat exchanger 200; and, the connecting pipe 300 includes a connecting section 320 extending in the up and down direction, the connecting end 310 is located at the top end of the connecting section 320, and the top end of the connecting section 320 extends to the pipe passing space 120.

[0074] It can be understood that, since the distance between the end of the indoor heat exchanger and the inner side surface of the housing 100 is relatively narrow, the connecting section 320 of the connecting pipe 300 can be arranged to extend in the up and down direction, so that the length of the connecting section 320 is as long as possible, which is convenient for the installer to operate the connection between the connecting pipe 300 and the on-line pipe 400, and ensures that the indoor unit has a low installation difficulty. And, the connecting end 310 of the connecting pipe 300 extends to the pipe passing space 120, so as to further facilitate the installer to operate the connection between the connecting pipe 300 and the on-line pipe 400, and ensure that the indoor unit has a low installation difficulty.

[0075] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in this embodiment, the indoor unit of the embedded air conditioner includes a refrigerant distributor 510 and a liquid collector 520.

[0076] The refrigerant distributor 510 and the liquid collector 520 are respectively connected to two flow ports of the indoor heat exchanger 200; and, the number of the connecting pipes 300 and the on-line pipes 400 is correspondingly set to two, and the two connecting pipes 300 are respectively connected to the indoor heat exchanger 200 through the refrigerant distributor 510 and the liquid collector 520; and, the length L of the connecting section 320 of one of the two connecting pipes 300 in the up and down direction is greater than the length H of the connecting section 320 of the other in the up and down direction.

[0077] It can be understood that, in the refrigeration system of the air conditioner, the actual number of the on-line pipes 400 is two. Furthermore, the actual number of the connecting pipes 300 is correspondingly two, and the two connecting pipes 300 need to be respectively connected to the indoor heat exchanger 200 through the refrigerant distributor 510 and the liquid collector 520 to ensure the normal operation of the refrigeration system of the air conditioner.

[0078] Moreover, by setting the connecting segments 320 of the two connecting pipes 300 to different lengths, it is possible to avoid the situation where the two connecting pipes 300 interfere with each other when connecting to the connecting pipes 400 (when the connecting pipes 300 and 400 are connected by welding, or when a flared structure needs to be provided at the connecting end 310 of the connecting pipe 300 to set up the connector 330), which facilitates the installer to operate the connection between the connecting pipe 300 and the connecting pipe 400, and ensures that the indoor unit has a low installation difficulty.

[0079] Specifically, the length L of the connecting segment of the connecting pipe connected to the accumulator can be greater than the length H of the connecting segment of the connecting pipe connected to the distributor to ensure the stable and efficient operation of the refrigeration system of the air conditioner.

[0080] Refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In this embodiment, the connecting end 310 is provided with a connector 330 for connecting the connecting pipe 400.

[0081] It can be understood that through the setting of the connector 330, the connecting pipe 300 can be quickly connected to the connecting pipe 400. And the connector 330 can be a nut connector or a ball socket quick connector.

[0082] Refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In this embodiment, the indoor unit of the embedded air conditioner includes a heat exchange protection member 610.

[0083] The heat exchange protection member 610 is arranged at the pipe passing opening 110. The heat exchange protection member 610 includes a shielding plate 611 extending forward from the pipe passing opening 110. The shielding plate 611 shields between the indoor heat exchanger 200 and the pipe passing space 120. The heat exchange protection member 610 is used to limit the contact between the connecting pipe 400 and the indoor heat exchanger 200.

[0084] It should be noted that the indoor heat exchanger 200 includes a plurality of heat exchange fins 210 arranged side by side in the horizontal direction and heat exchange pipes 220 horizontally penetrating through the plurality of heat exchange fins 210. The heat exchange pipes 220 include bent segments 221. The bent segments 221 protrude from the heat exchange fins 210 of the adjacent pipe passing spaces 120. These bent segments 221 are of the adjacent pipe passing spaces 120 and are relatively numerous.

[0085] Furthermore, through the arrangement of the heat exchange protection member 610, when the connection pipe 400 is passed forward through the pipe passing port 110 and the pipe passing space 120 at the rear side of the housing 100, the situation that the connection pipe 400 abuts against the indoor heat exchanger 200 and cannot be passed through to the connection end 310 can be avoided. This facilitates the installation of the indoor unit by the installer and further reduces the installation difficulty of the indoor unit.

[0086] Meanwhile, through the arrangement of the heat exchange protection member 610, the connection pipe 400 can be prevented from abutting against the indoor heat exchanger 200 and causing damage to each other, ensuring that the installation of the indoor unit can proceed smoothly.

[0087] In addition, the heat exchange protection member 610 can specifically be arranged on the base 140.

[0088] Referring to Figure 6 , in this embodiment, the indoor unit of the embedded air conditioner includes an indoor fan 710.

[0089] The indoor fan 710 is arranged inside the housing 100. The indoor fan 710 is located below the indoor heat exchanger 200. The indoor fan 710 is used to cause the air flow in the indoor space to enter the housing 100, exchange heat with the indoor heat exchanger 200, and then flow out of the housing 100 into the indoor space.

[0090] Referring to Figure 5 and Figure 6 , in this embodiment, the indoor heat exchanger 200 includes a top-rear heat exchange section 230 that is inclined above and behind the indoor fan 710, and the baffle 611 is arranged corresponding to the top-rear heat exchange section 230.

[0091] It can be understood that after keeping the connection pipe 400 parallel to the pipe passing space 120, the connection pipe 400 can be smoothly passed forward through the pipe passing port 110 and the pipe passing space 120 at the rear side of the housing 100, and the situation that the connection pipe 400 abuts against the indoor heat exchanger 200 is less likely to occur. When initially passing the connection pipe 400 through the pipe passing port 110 and the pipe passing space 120, the probability that the connection pipe 400 abuts against the indoor heat exchanger 200 is relatively high. Therefore, the heat exchange protection member 610 can be arranged in the rear section of the pipe passing space 120, that is, the baffle 611 can be arranged only corresponding to the top-rear heat exchange section 230.

[0092] In addition, the indoor heat exchanger 200 may further include a top-front heat exchange section 240 and a front heat exchange section 250. The top-front heat exchange section 240 is inclined above and in front of the indoor fan 710, and the front heat exchange section 250 is arranged in front of the indoor fan 710. This enables the entire indoor heat exchanger 200 to surround the indoor fan 710, ensuring the heat exchange efficiency of the indoor heat exchanger 200.

[0093] Referring to Figure 4And Figure 5 , in this embodiment, the indoor unit of the embedded air conditioner includes a fan drive motor 720.

[0094] The fan drive motor 720 is disposed within the housing 100. The fan drive motor 720 is drivingly connected to the indoor fan 710, and the fan drive motor 720 is located below the pipe passing space 120.

[0095] The pipe passing space 120 is located between the housing 100, the indoor heat exchanger 200, and the fan drive motor 720. The indoor heat exchanger 200 is located on one side of the pipe passing space 120 in the left - right direction, and the housing 100 is located on the other side of the pipe passing space 120 in the left - right direction and above the pipe passing space 120.

[0096] It can be understood that the construction of the pipe passing space 120 is achieved through the above - mentioned housing 100, indoor heat exchanger 200, and fan drive motor 720.

[0097] Refer to Figure 4 and Figure 5 , in this embodiment, the indoor unit of the embedded air conditioner includes a motor protection housing 620.

[0098] The motor protection housing 620 covers the upper part of the fan drive motor 720, and the motor protection housing 620 is located below the pipe passing space 120. The motor protection housing 620 is used to limit the contact between the connecting pipe 400 and the fan drive motor 720.

[0099] It can be understood that through the setting of the motor protection housing 620, when the connecting pipe 400 passes forward through the pipe passing opening 110 and the pipe passing space 120 at the rear side of the housing 100, the situation that the connecting pipe 400 cannot pass through to the connection end 310 due to contacting the fan drive motor 720 can be avoided. This facilitates the installation of the indoor unit by the installer and further reduces the installation difficulty of the indoor unit.

[0100] Meanwhile, through the setting of the motor protection housing 620, the connecting pipe 400 can be prevented from contacting the indoor heat exchanger 200 and causing damage to each other, ensuring the smooth progress of the installation of the indoor unit.

[0101] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , in this embodiment, the housing 100 further includes a base 140 and a peripheral frame 150.

[0102] The pipe passing opening 110 is formed in the base 140, and both the indoor fan 710 and the indoor heat exchanger 200 are disposed on the base 140.

[0103] The outer frame 150 includes an upper top plate 151 surrounding above the base 140, a lower bottom plate 152 surrounding below the base 140, a left side plate 153 surrounding the left side of the base 140, and a right side plate 154 surrounding the right side of the base 140. The front cover 130 is connected to the front of the base 140 and the outer frame 150.

[0104] Moreover, the upper top plate 151 is connected between the left side plate 153 and the right side plate 154, the lower bottom plate 152 is connected between the left side plate 153 and the right side plate 154, and the upper top plate 151 is located above the lower bottom plate 152.

[0105] The pipe passing space 120 is located between the left side plate 153 and the indoor heat exchanger 200, and between the upper top plate 151 and the fan driving motor 720.

[0106] It can be understood that through the specific setting of the housing 100, the indoor unit can be embedded into the cabinet cavity 810. Specifically, the base 140 can be fixed to the rear side wall of the cabinet cavity 810, and the outer frame 150 can be placed on the inner bottom surface of the cabinet cavity 810, so that the gravity of the entire indoor unit is evenly distributed to each part of the cabinet 800, ensuring the connection strength between the indoor unit and the cabinet 800, and at the same time avoiding the deformation of the cabinet 800 due to the single connection method with the indoor unit (for example, the indoor unit is only connected to the rear side of the cabinet cavity 810 / only placed on the inner bottom surface of the cabinet cavity 810).

[0107] Furthermore, the passing space can be constructed on the above-mentioned housing 100.
