The temperature difference between the inside and outside of the electric control box is large, and condensation is easy to form on the inner wall of the electric control box, increasing the risk of short circuit and loss of control of the electric control box.

[0003] In order to reduce or avoid condensation in an electric control box, an air conditioner is disclosed in the related art, including a shell, an air outlet and an air inlet are arranged on the shell, a receiving cavity is formed on the side of the shell near the air outlet, the receiving cavity is connected with the air outlet, a fan is arranged in the receiving cavity, and an electric control box is arranged on the side of the receiving cavity near the air outlet. The electric control box further includes: a box body, a sub-air inlet arranged on the side of the box body near the air outlet, and a sub-air outlet arranged on the side of the box body near the receiving cavity. The cooling air from the air outlet enters the box body through the sub-air inlet, and enters the receiving cavity through the sub-air outlet after intersecting with the hot air in the box body.

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The disclosed embodiment provides a duct type air conditioner indoor unit to reduce or avoid condensation in an electric control box when the electric control box is sealed.

[0009] In some embodiments, the indoor unit of a duct-type air conditioner includes a shell, an evaporator and an electrical control box, wherein the shell encloses and defines a accommodating space, the accommodating space is divided into a refrigeration area and a temperature changing area along the width direction of the shell, and the shell is provided with a first air inlet and an air outlet corresponding to the refrigeration area; the evaporator is arranged in the refrigeration area corresponding to the first air inlet and the air outlet; the electrical control box is arranged in the shell, and is arranged outside the accommodating space corresponding to the temperature changing area.

[0010] Since the electric control box and the cooling area inside the shell have a variable temperature area as a buffer, the temperature difference between the inside and outside of the electric control box is reduced, and condensation in the electric control box is alleviated or avoided; the interior of the electric control box is relatively independent of the interior of the shell, and the air flowing through the cooling area or the variable temperature area will not enter the interior of the electric control box, thereby improving the protection effect of the electric control box on the internal circuit boards and wiring terminals.

[0022] In this way, the indoor unit of the duct type air conditioner can have more installation methods and usage methods. When the first air inlet and the second air inlet are used at the same time, the air volume of the indoor unit of the duct type air conditioner can also be increased.

[0023] In some embodiments, the shell further includes a top plate, a bottom plate and a water receiving tray, wherein the water receiving tray corresponds to the refrigeration area and the temperature changing area, and the water receiving tray avoids the installation space; the bottom plate corresponds to the refrigeration area, the temperature changing area and the installation space.

[0024] The water pan is installed in a space-avoiding manner, so that the electric control box can be set to a larger volume and water leakage from the water pan can be reduced or avoided.

[0025] In some embodiments, the shell further includes a partition assembly, a top end of the partition assembly is connected to the top plate, and a bottom plate is connected to the bottom plate, and the partition assembly encloses the accommodating space inwardly and defines the installation space outwardly.

[0026] A partition assembly is provided, which is beneficial to the processing and forming of the shell.

[0027] In some embodiments, the partition assembly includes a transverse partition and a vertical partition. The transverse partition extends along the length direction of the shell and one end is connected to the second side panel; the vertical partition extends along the depth direction of the shell, the front end of the vertical partition is connected to the front panel, and the rear end of the vertical partition is connected to the other end of the transverse partition.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0049] The indoor unit of the duct-type air conditioner can be integrated and installed in the indoor ceiling, which has the advantages of beautiful appearance and saving indoor space. When installing the indoor unit of the duct-type air conditioner, the thickness of the indoor unit of the duct-type air conditioner affects the thickness of the ceiling, and its own depth affects the depth of the ceiling. Therefore, the indoor unit of the duct-type air conditioner is also developing in the direction of thinner and narrower. After the size of the indoor unit of the duct-type air conditioner is further compressed, the integration degree of the electric control box and the air conditioner shell is higher. This also leads to further improvement of the heat exchange between the electric control box and the air conditioner shell. When the temperature difference between the inside and outside of the electric control box is relatively large, condensation is easy to form on the inner and outer walls of the electric control box. If the condensation drips on the computer board or the terminal block, the electric control box is at risk of short circuit and loss of control.

[0050] In order to reduce condensation in an electric control box, a related art discloses an air conditioner, comprising a housing, an air outlet and an air inlet are arranged on the housing, a housing is formed on one side of the housing near the air outlet, the housing is connected to the air outlet, a fan is arranged in the housing, and an electric control box is arranged on the side of the housing near the air outlet. The electric control box further comprises: a box body, a sub-air inlet arranged on the side of the box body near the air outlet, and a sub-air outlet arranged on the side of the box body near the housing chamber. The cooling air from the air outlet enters the box body through the sub-air inlet, and enters the housing chamber through the sub-air outlet after intersecting with the hot air in the box body. By setting up wind circulation between the air outlet, the electric control box, and the housing chamber, the air in the electric control box is made to flow, the temperature in the electric control box is reduced, the temperature difference between the inside and outside of the electric control box is reduced, and the condensation problem on the side wall of the electric control box is solved. The related art reduces condensation in the air conditioner by allowing a part of the air to flow through the electric control box, thereby reducing the temperature difference between the electric control box and the inside of the air conditioner housing. The problem with the related technology is that the interior of the electrical control box is connected to the interior of the shell. When the air conditioner operates in cooling or dehumidification mode in a high humidity environment, water vapor in the air flowing through the electrical control box tends to form condensation inside the electrical control box, increasing the risk of short circuit and loss of control of the computer board or wiring terminals inside the electrical control box.

[0051] The electric control box can better protect the circuit board and the wiring terminals in a closed environment. In order to reduce or avoid condensation in the electric control box, Figure 1-4As shown, the embodiment of the present disclosure provides a duct type air-conditioning indoor unit, which includes a shell 100, an evaporator 200 and an electric control box 300, wherein the shell 100 encloses and defines an accommodation space, and the accommodation space is divided into a refrigeration area 101 and a temperature changing area 102 along the width direction of the shell 100, and the shell 100 is provided with a first air inlet and an air outlet corresponding to the refrigeration area 101; the evaporator 200 is arranged in the refrigeration area 101 corresponding to the first air inlet and the air outlet; the electric control box 300 is arranged in the shell 100, and is arranged outside the accommodation space corresponding to the temperature changing area 102.

[0052] Duct air conditioner, also known as duct air conditioner or duct central air conditioner, is a type of central air conditioner and an upgraded product of traditional air conditioner. It adopts a one-to-one form, that is, one outdoor unit corresponds to one indoor unit, and the indoor and outdoor units are connected by copper pipes, with air as the transmission medium. When working, the outdoor unit draws air into the air supply duct, and after cooling or heating, it is mixed with the return air and transported to the room, thereby adjusting the indoor temperature.

[0053] The duct air conditioner indoor unit provided in the embodiment of the present disclosure is the indoor unit part of the duct air conditioner. The duct air conditioner indoor unit includes a housing 100, and the housing 100 encloses and defines an accommodation space. When the user is facing the air outlet of the duct air conditioner indoor unit, the left and right direction is the length direction of the duct air conditioner indoor unit, the front and back direction is the depth direction of the duct air conditioner indoor unit, and the up and down direction is the height direction of the duct air conditioner indoor unit. The accommodation space of the housing 100 is divided into a refrigeration area 101 and a temperature change area 102 along the length direction. The housing 100 is provided with a first air inlet and an air outlet corresponding to the refrigeration area 101, which are connected to the refrigeration area 101. The evaporator 200 is arranged in the refrigeration area 101. When the duct air conditioner indoor unit is in operation, air enters the refrigeration area 101 from the first air inlet, then flows through the evaporator 200 to exchange heat with the evaporator 200, and then is sent out from the air outlet. That is, the refrigeration area 101 inside the housing 100 is the space where air heat exchange and air flow mainly take place, and since the temperature-changing area 102 is located on one side of the refrigeration area 101, air flow is less. In the refrigeration area 101, heat convection and heat transfer using air as the medium are more, while in the temperature-changing area 102, heat convection and heat transfer using air as the medium are less.

[0054] The electric control box 300 is arranged in the shell 100 and is located outside the accommodating space. The electric control box 300 is arranged corresponding to the temperature-changing area 102, so that there is a temperature-changing area 102 as a buffer between the electric control box 300 and the refrigeration area 101 where the heat exchange is more intense. When the air conditioner is running in cooling mode or dehumidification mode, the heat exchange between the electric control box 300 and the inside of the shell 100 is less, which can reduce the temperature difference between the electric control box 300 and the refrigeration area 101 of the shell 100. Since the heat exchange between the electric control box 300 and the refrigeration area 101 is less, the internal temperature of the electric control box 300 is higher than that of the refrigeration area 101, and the temperature difference between the electric control box 300 and the environment is also smaller. In this way, the formation of condensation on the inner and outer walls of the electric control box 300 when the air conditioner is running in cooling or dehumidification mode is reduced or avoided.

[0055] When using the duct-type air-conditioning indoor unit provided by the embodiment of the present disclosure, since the electric control box and the internal refrigeration area 101 of the shell 100 have the variable temperature area 102 as a buffer, the temperature difference between the inside and outside of the electric control box is reduced, and the condensation phenomenon of the electric control box is alleviated or avoided; the interior of the electric control box is relatively independent of the interior of the shell 100, and the air flowing through the refrigeration area 101 or the variable temperature area 102 will not enter the interior of the electric control box, thereby improving the protection effect of the electric control box on the internal circuit boards and terminal blocks.

[0056] Optionally, the housing 100 is recessed to form an installation space outside the housing 100 , the installation space corresponds to the temperature control area 102 , and the electric control box 300 is disposed in the installation space.

[0057] As an implementation method, the bottom of the housing 100 is recessed upward to form an installation space, and the installation space corresponds to the temperature-changing area 102, so that there is a temperature-changing area 102 as a buffer between the installation space and the cooling area 101. The upward recessed bottom of the housing 100 can make it easy to disassemble and wire the electric control box 300 from the bottom up. For the duct-type air conditioner indoor unit with an integrated inspection port and a return air port, or an inspection port opened at the bottom, it is convenient for users or maintenance personnel to wire the electric control box.

[0058] As another embodiment, the front side of the housing 100 is recessed backward or the left and right sides are recessed inward. These recessed forms of the housing 100 can make the duct-type air conditioner indoor unit have a more neat appearance as a whole, which is conducive to installing the duct-type air conditioner indoor unit in the ceiling. In addition, the housing 100 itself has a strong structural rigidity. Compared with the form in which the electric control box is hung on one side of the housing 100, the recessed form of the housing 100 can improve the overall structural strength of the housing 100 and the electric control box.

[0059] Optionally, the front side of the housing 100 is recessed inward to form an installation space, and the operation direction of the electric control box 300 is located at the front side of the electric control box 300 .

[0060] For the duct type air conditioner indoor unit, the air outlet is usually opened on the front side of the housing 100. The front side of the housing 100 is recessed inwards and the operation direction of the electric control box 300 is also located on the front side, so that the air outlet inspection port of the duct type air conditioner indoor unit can be integrated, which is beneficial to the installation and maintenance of the duct type air conditioner indoor unit, and can make the duct type air conditioner indoor unit have a better overall appearance after the ceiling is completed.

[0061] Optionally, the duct type air conditioner indoor unit further includes an air outlet assembly, and the air outlet assembly covers the electric control box 300 in the length direction.

[0062] The ceiling needs to be provided with an installation window corresponding to the size of the air outlet assembly. The air outlet assembly covers the electric control box 300 in the length direction. Through the installation window, the electric box housing can be easily repaired and wired. This further enables the duct type air conditioner indoor unit to realize an integrated air outlet inspection port, so that the duct type air conditioner indoor unit has a better overall appearance after the ceiling is completed.

[0063] Optionally, the shell includes a front panel 110 and a back panel 120, wherein the front panel 110 is provided with an air outlet, and the electric control box 300 is flush with the front panel 110 at the front side; the back panel 120 is opposite to the front panel 110, and the back panel 120 is provided with a first air inlet.

[0064] The front panel 110 of the housing is provided with an air outlet, and the electric control box 300 is flush with the front panel 110 at the front side. In this way, the duct type air conditioner indoor unit has a more neat and beautiful appearance. In addition, the way in which the electric control box 300 is aligned with the front panel 110 is convenient for maintenance personnel or users to perform maintenance and wiring operations on the electric control box 300. The back panel 120 is provided with a first air inlet, and air flows from the back to the front and flows out from the air outlet of the front panel 110. In this way, the air flow path is clearer and it is not easy to enter the temperature change area 102.

[0065] Optionally, the duct type air conditioner indoor unit further includes a fan 400 , which is fixed to the front panel 110 and located in the refrigeration area 101 , and the fan 400 is assembled and disassembled together with the front panel 110 .

[0066] The fan 400 can be disassembled and assembled from the front of the front panel 110, which is not only convenient for assembling the duct-type air-conditioning indoor unit on the production line, but also allows maintenance personnel to easily disassemble and assemble the duct-type air-conditioning indoor unit after the duct-type air-conditioning indoor unit is installed inside the ceiling.

[0067] Optionally, the shell also includes a first side panel 130 and a second side panel 140, the first side panel 130 is provided with a second air inlet, and the first side panel 130, the first side panel 130, the first part of the front panel 110, and the first part of the back panel 120 form a refrigeration area 101; the second side panel 140 is opposite to the first side panel 130, and the second side panel 140, the second part of the front panel 110, and the second part of the back panel 120 form a temperature change area 102; wherein the evaporator 200 includes a first part and a second part connected by a bend, the first part of the evaporator 200 corresponds to the first air inlet, and the second part corresponds to the second air inlet.

[0068] The first side plate 130 corresponds to the cooling area 101, and the second side plate 140 corresponds to the warming area 102. The first side plate 130 is provided with a second air inlet. In some installation scenarios, only the second air inlet can be used; in other installation scenarios, the first air inlet and the second air inlet are used together to intake air. In this way, the duct-type air conditioner indoor unit can have more installation and use methods. When the first air inlet and the second air inlet are used at the same time, the air volume of the duct-type air conditioner indoor unit can also be increased.

[0069] Optionally, the shell further includes a top plate 160, a bottom plate 170 and a water receiving tray 180, wherein the water receiving tray 180 corresponds to the refrigeration area 101 and the temperature changing area 102, and the water receiving tray 180 avoids the installation space; the bottom plate 170 corresponds to the refrigeration area 101, the temperature changing area 102 and the installation space.

[0070] The bottom plate 170 and the bottom plate 170 are arranged opposite to each other, and the top plate 160 and the bottom plate 170 cover the refrigeration area 101, the temperature-changing area 102 and the installation space. In this way, the indoor unit of the duct-type air conditioner can be better protected. The water receiving pan 180 only corresponds to the refrigeration area 101 and the temperature-changing area 102, and avoids the installation space. In this way, the electric control box can be set to a larger volume, and water leakage of the water receiving pan 180 can be reduced or avoided.

[0071] Optionally, the duct-type air-conditioning indoor unit further includes a water receiving pump, which is disposed in the temperature-changing area 102 , and whose water receiving end extends to the water receiving tray 180 .

[0072] This can improve the space utilization of the temperature changing area 102 .

[0073] Optionally, the shell further includes a partition assembly 150 , the top end of the partition assembly 150 is connected to the top plate 160 , and the bottom plate 170 is connected to the bottom plate 170 , and the partition assembly 150 encloses the accommodating space inwardly and defines the installation space outwardly.

[0074] The partition assembly 150 is used to separate the external installation space from the internal accommodation space. The partition assembly 150 is provided to facilitate the processing and forming of the shell.

[0075] Optionally, a heat insulation layer is provided between the outer wall of the partition assembly 150 and the electric control box 300 .

[0076] In this way, the heat transfer between the refrigeration area 101 and the electric control box 300 can be further reduced, thereby alleviating or avoiding condensation in the electric control box 300 .

[0077] Optionally, the partition assembly 150 includes a transverse partition 151 and a vertical partition 152, wherein the transverse partition 151 extends along the length direction of the shell 100 and one end is connected to the second side panel 140; the vertical partition 152 extends along the depth direction of the shell 100, the front end of the vertical partition 152 is connected to the front panel 110, and the rear end of the vertical partition 152 is connected to the other end of the transverse partition 151.

[0078] The length of the first side plate 130 is equal to the depth of the housing, and the sum of the length of the second side plate 140 and the length of the vertical partition 152 is equal to the depth of the housing. The length of the back plate 120 is equal to the length of the housing, and the sum of the length of the front panel 110 and the length of the horizontal partition 151 is equal to the length of the housing. In this way, the installation space is a missing corner of the entire housing, and the shape is relatively regular, which is conducive to the arrangement and installation of the electric control box 300.

[0079] Optionally, the length of the refrigeration area 101 is equal to that of the front panel 110 , and the length of the temperature changing area 102 is equal to that of the transverse partition 151 .

[0080] In this way, the refrigeration area 101 is a regular space, and the temperature change area 102 is also a regular space, which is conducive to the arrangement of the heat exchanger and the fan 400.

[0081] Optionally, the partition assembly 150 and the top plate 160 are an integral structure.

[0082] This modular design approach is conducive to the assembly of the indoor unit of the duct type air conditioner.

[0084] This can improve the utilization rate of the accommodation space.

[0085] Optionally, the air-conditioning indoor unit further includes a heat insulation board, which is arranged in the accommodating space to separate the accommodating space into a cooling area 101 and a temperature changing area 102 .

[0086] This arrangement can further reduce the heat convection between the cooling area 101 and the temperature changing area 102, thereby reducing the heat exchange between the temperature changing area 102 and the electrical box. When the duct type air conditioner indoor unit is running, the temperature difference between the inside and outside of the electrical control box is small, and condensation is not easy to form.
