Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to an indoor unit and air conditioning unit. Background Technology

[0002] In recent years, residential central air conditioning has seen a continuous increase in market share due to its advantages of aesthetically pleasing installation and small footprint, with ceiling-mounted indoor units. Kitchen air conditioners, as a new type of air conditioning product, are attracting widespread consumer attention. Ceiling-mounted kitchen air conditioners, using a full ceiling (the entire kitchen ceiling is suspended), are becoming increasingly popular. However, users typically place the indoor unit directly above the stove, resulting in an excessively thick ceiling that can make users feel cramped. Furthermore, grease and impurities from the stove can clog the air intake of the kitchen air conditioner, reducing its heat exchange efficiency. Additionally, condensation produced by the indoor unit during cooling can drip onto the stove or users, reducing their comfort. Summary of the Invention

[0003] In order to solve the technical problems of excessive space occupation and low heat exchange efficiency of existing kitchen air conditioner indoor units, which lead to a decrease in user comfort, an indoor unit and air conditioning unit are provided that utilizes spacing to increase the horizontal dimension to reduce the height and keep the air inlet away from oil fumes.

[0004] An indoor unit, comprising: First heat exchange section; The second heat exchange section for dehumidification is disposed on one side of the first heat exchange section in the horizontal direction, and there is a gap between the first heat exchange section and the second heat exchange section. After entering the indoor unit, the gas flows through the second heat exchange section and the first heat exchange section in sequence before being discharged from the indoor unit.

[0005] The first heat exchange section includes a first housing, the second heat exchange section includes a second housing, and a connecting pipe is provided between the first housing and the second housing.

[0006] The connecting pipeline includes flexible air ducts.

[0007] The first housing has a first air outlet on its bottom surface and a first air inlet on its side surface. The second housing has a second air inlet on its bottom surface and a second air outlet on its side surface. The first air inlet and the second air outlet are connected by the connecting pipe.

[0008] The first heat exchange section further includes a first heat exchanger and a fan. The first heat exchanger and the fan are arranged side by side in the first housing along the thickness direction of the first housing. The first air outlet is located below the first heat exchanger or below the fan.

[0009] The first heat exchange section includes a first plate heat exchanger, and the plane in which the first plate heat exchanger is located is parallel to the horizontal plane.

[0010] The second heat exchange section further includes a second heat exchanger and a water receiving tray. Both the second heat exchanger and the water receiving tray are disposed inside the second housing, and the water receiving tray is located below the second heat exchanger.

[0011] The second heat exchange section includes a second plate heat exchanger, and the plane in which the second plate heat exchanger is located is perpendicular to the horizontal plane.

[0012] The indoor unit includes a housing, and the first heat exchange part and the second heat exchange part are both disposed inside the housing. The first heat exchange part is located at one end of the housing in the horizontal direction, and the second heat exchange part is located at the other end of the housing in the horizontal direction.

[0013] The indoor unit also includes a flexible air duct, which is disposed between the first heat exchange section and the second heat exchange section, and the flexible air duct constitutes part of the outer shell.

[0014] The first heat exchange section includes a first heat exchanger, and the second heat exchange section includes a second heat exchanger. The first heat exchanger and the second heat exchanger are arranged in parallel.

[0015] An air conditioning unit includes the indoor unit described above.

[0016] The indoor unit and air conditioning unit provided by this invention horizontally arrange the first and second heat exchange sections with a gap between them, utilizing horizontal space to replace vertical space, thereby reducing the space occupied by the indoor unit and the required ceiling height. Simultaneously, the horizontal gap creates a distance between the air outlet and return air inlet of the indoor unit. While ensuring effective heat exchange between the air outlet and stoves, the return air inlet is kept as far away as possible from pollution sources such as stoves, preventing oil fume contamination of the unit and reducing the frequency of filter cleaning. The second heat exchange section also dehumidifies the air, preventing condensate from dripping onto stoves or users and affecting user comfort. Furthermore, the first heat exchange section does not require dehumidification and can be horizontally arranged, further reducing the required ceiling height. The flexible duct facilitates adjustment of the positions of the indoor unit's air outlet and return air inlet, and the flexible duct can be folded for convenient transportation of the indoor unit.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0019] like Figure 1 The indoor unit shown includes: a first heat exchange section 1; and a second heat exchange section 2 for dehumidification. The second heat exchange section 2 is disposed on one side of the first heat exchange section 1 in a horizontal direction, and there is a gap between the first heat exchange section 1 and the second heat exchange section 2. After entering the indoor unit, the gas flows sequentially through the second heat exchange section 2 and the first heat exchange section 1 before being discharged from the indoor unit. By horizontally arranging the first heat exchange section 1 and the second heat exchange section 2 with a gap, the horizontal space is used to replace the vertical space, thereby reducing the space occupied by the indoor unit and reducing the height required for the ceiling. At the same time, the horizontal gap ensures that there is a distance between the air outlet and the return air outlet of the indoor unit. While ensuring effective heat exchange between the air outlet and the stove, the return air outlet is kept as far away from the stove and other pollution sources as possible, thereby preventing oil fume pollution of the unit and reducing the frequency of filter cleaning. The second heat exchange section 2 can also dehumidify the gas, preventing condensate from dripping onto the stove or the user and affecting the user's comfort.

[0020] The first heat exchange unit 1 includes a first housing 11, and the second heat exchange unit 2 includes a second housing 21. A connecting pipe 3 is provided between the first housing 11 and the second housing 21. By setting the first housing 11 and the second housing 21, the first heat exchange unit 1 and the second heat exchange unit 2 are configured as separate units. Users can arrange the first heat exchange unit 1 and the second heat exchange unit 2 according to actual needs, thereby reducing the space occupied by the indoor unit. At the same time, the connecting pipe 3 ensures the normal operation of the indoor unit.

[0021] Preferably, the connecting pipe 3 includes a flexible duct. This facilitates the adjustment of the positions of the indoor unit's air outlet and return air inlet. The horizontal and / or vertical bends of the flexible duct can be used to increase the arrangement range of the second heat exchange section 2, further keeping the indoor unit's return air inlet away from appliances such as stoves, reducing the possibility of the indoor unit being contaminated. At the same time, the flexible duct can be folded to facilitate the transportation of the indoor unit.

[0022] Since ceiling-mounted air conditioners generally require air to enter and exit from the bottom, a first air outlet 12 is provided on the bottom surface of the first housing 11, a first air inlet 13 is provided on the side surface of the first housing 11, a second air inlet 22 is provided on the bottom surface of the second housing 21, and a second air outlet 23 is provided on the side surface of the second housing 21. The first air inlet 13 and the second air outlet 23 are connected through the connecting pipe 3.

[0023] The first heat exchange section 1 further includes a first heat exchanger 14 and a fan 15. The first heat exchanger 14 and the fan 15 are arranged side by side in the first housing 11 along the thickness direction of the first housing 11. The first air outlet 12 is located below the first heat exchanger 14 or below the fan 15. The fan 15 can force the gas to enter the second housing 21 from the second air inlet 22 of the second heat exchanger, and then pass through the second heat exchange section 2, the connecting pipe 3, the first air inlet 13, the first heat exchanger 14, the fan 15 and the first air outlet 12 in sequence before being discharged from the indoor unit. At the same time, the second heat exchange section 2 and / or the first heat exchanger 14 can perform heat exchange and dehumidification operations on the gas, thereby completing the gas heat exchange cycle.

[0024] The first heat exchange section 1 includes a first plate heat exchanger, and the plane of the first plate heat exchanger is parallel to the horizontal plane. By utilizing the first plate heat exchanger, the vertical dimension of the first heat exchange section 1 is minimized as much as possible, thereby reducing the space occupied by the indoor unit.

[0025] Preferably, the first heat exchange section 1 is the main heat exchange section for heating or cooling the gas, and the second heat exchange section 2 is used for pre-cooling or dehumidifying the gas.

[0026] Specifically, the second heat exchange section 2 further includes a second heat exchanger 24 and a water collection tray 25. Both the second heat exchanger 24 and the water collection tray 25 are disposed within the second housing 21, with the water collection tray 25 located below the second heat exchanger 24. The second heat exchanger 24 is used to pre-cool or dehumidify the gas. Condensation is generated when the gas passes through the second heat exchanger 24, and the water collection tray 25 is provided to collect this condensation. Furthermore, the dehumidification of the gas by the second heat exchange section 2 prevents condensation from forming at the first heat exchange section 1 and dripping onto the stove or the user, thus ensuring user comfort.

[0027] Since the second heat exchange section 2 is used for dehumidifying the gas, it requires a relatively small cooling capacity. Furthermore, to reduce the size of the drip tray 25, the second heat exchange section 2 includes a second plate heat exchanger, the plane of which is perpendicular to the horizontal plane. By reducing the cooling capacity required for dehumidifying the gas, the size of the drip tray 25 is reduced, thus preventing the drip tray 25 from obstructing the gas flow area and effectively increasing the dehumidification and heat exchange efficiency of the indoor unit.

[0028] In another embodiment, the indoor unit includes a housing, with both the first heat exchanger 1 and the second heat exchanger 2 disposed within the housing. The first heat exchanger 1 is located at one end of the housing in the horizontal direction, and the second heat exchanger 2 is located at the other end of the housing in the horizontal direction. That is, both the first heat exchanger 1 and the second heat exchanger 2 are disposed within the same housing. By flattening the housing design, the horizontal dimension of the housing is increased, thereby reducing the vertical dimension of the housing, thus reducing the space occupied by the indoor unit and making full use of the integrated ceiling.

[0029] The indoor unit also includes a flexible duct, which is disposed between the first heat exchange section 1 and the second heat exchange section 2, and forms part of the outer casing. The flexible duct facilitates the adjustment of the positions of the air outlet and return air inlet of the indoor unit. Horizontal and / or vertical bends of the flexible duct can be used to increase the applicability of the outer casing, further keeping the return air inlet of the indoor unit away from stoves, reducing the possibility of contamination. At the same time, the flexible duct can be folded for convenient transportation of the indoor unit.

[0030] The first heat exchange section 1 includes a first heat exchanger 14, and the second heat exchange section 2 includes a second heat exchanger 24. The first heat exchanger 14 and the second heat exchanger 24 are arranged in parallel.

[0031] When the outdoor unit of the air conditioning unit used in the indoor unit is a three-pipe outdoor unit, the first heat exchange section 1 can be connected to the high-pressure gas pipe and the liquid pipe for heating, and the second heat exchange section 2 can be connected to the low-pressure gas pipe and the liquid pipe for cooling and dehumidification. This allows for multiple heat exchange modes, such as standalone cooling mode (using the first heat exchange section 1 for cooling alone or using both the first heat exchange section 1 and the second heat exchange section 2 for cooling simultaneously), standalone heating mode (using the first heat exchange section 1 for heating alone), dehumidification mode (using the second heat exchange section 2 for cooling and dehumidification alone), and reheat dehumidification mode (using the first heat exchange section 1 for heating and the second heat exchange section 2 for cooling simultaneously).

[0032] An air conditioning unit includes the indoor unit described above.

[0033] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
