Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an air conditioner indoor unit with air cavity-assisted heat exchange. Background Technology

[0002] An air conditioner mainly consists of an indoor unit and an outdoor unit, which work together to achieve cooling, heating, and air conditioning. Typically, the indoor unit includes a casing, a fan assembly (i.e., a cross-flow fan), and a heat exchanger. The casing has an air inlet, an air outlet, and an air cavity connecting the inlet and outlet. The cross-flow fan and heat exchanger are both installed in the air cavity. When the cross-flow fan is running, air is drawn into the air cavity through the inlet, exchanges heat with the heat exchanger, and then flows out through the outlet, thus achieving cooling or heating.

[0003] In existing air conditioner indoor units, the indoor unit casing is mainly made of injection-molded sheet metal, while a small number of air conditioner indoor units use iron alloy sheet metal to make the indoor unit casing.

[0004] When the indoor unit casing uses injection-molded panels, it is typically a split structure, assembled from several large injection-molded panels that interlock. These panels, once joined, form an internal air cavity for mounting the cross-flow fan and heat exchanger. However, in cooling mode, the indoor unit needs to handle condensation on the cooled surfaces and the back. This requires attaching a heat insulation layer to the injection-molded panel on the back of the casing. This insulation layer can be made of polystyrene or similar foamed polymer insulation materials to control and eliminate condensation. Adding this insulation layer affects the appearance of the indoor unit and increases its complexity, assembly difficulty, and cost. Furthermore, plastic insulation layers are not durable, easily deformed, and cannot withstand high-temperature sterilization; in fact, they can promote the growth of bacteria and mold. In addition, the installation of the insulation layer increases the size of the gaps between the two adjacent injection-molded panels of the split-type air conditioner indoor unit; thus, it is also necessary to apply some felt-like material to the injection-molded panel joints to prevent resonance and absorb a small amount of condensation when necessary to prevent water droplets from falling. The installation of felt-like material makes it easier for mold to grow.

[0005] When the indoor unit casing is made of iron alloy sheet metal, this type of air conditioner indoor unit is not common. It is usually used in central air conditioning systems and commercial units that are embedded in the plasterboard of the building or installed on the roof. The fan of this type of air conditioner indoor unit is usually an axial centrifugal fan. Foam material needs to be added to the low-temperature area of ​​the iron alloy sheet metal casing, and foam padding or wrapping is required at the heat exchanger and cold air duct to achieve waterproofing on the back. This also has problems such as affecting the appearance of the air conditioner indoor unit, high cost, mold growth, and inability to withstand high-temperature sterilization. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an air conditioner indoor unit with air cavity assisted heat exchange, so that both the indoor unit casing and the air cavity participate in heat exchange, thereby suppressing condensation in cooling mode and avoiding the mold growth problem caused by the addition of insulation layers, felt, foam and other materials for waterproofing. At the same time, it can make the air outlet temperature more uniform during operation.

[0007] To achieve the above objectives, this utility model provides an air conditioning indoor unit with air cavity assisted heat exchange, including an indoor unit housing, a main air inlet and an air outlet both disposed on the indoor unit housing, an air cavity disposed within the indoor unit housing, and a fan assembly and a heat exchanger both installed in the air cavity. The air cavity connects the main air inlet and the air outlet. At least a portion of the indoor unit housing is a shell heat-conducting part made of thermally conductive material, and the main air inlet is provided on the shell heat-conducting part.

[0008] In cooling mode, the temperature of the air entering the air cavity from the main air inlet is higher than the temperature of the heat-conducting part of the casing. The air at the main air inlet exchanges heat with the heat-conducting part of the casing, which cools the air entering the air cavity and heats the indoor unit casing, making the temperature of the indoor unit casing higher than the dew point of the air around the air cavity.

[0009] Furthermore, an optional solution for the indoor unit of the air conditioner is that the heat-conducting part of the shell is provided with an expanded part, which is a groove structure, a corrugated structure, or a porous honeycomb structure.

[0010] Furthermore, the optional configuration of the indoor unit of the air conditioner is as follows: the material of the heat-conducting part of the shell is aluminum alloy, magnesium alloy, iron alloy, or copper; the heat-conducting part of the shell is a sheet metal part, an extruded part, a stamped part, a die-cast part, or a machined part.

[0011] Furthermore, an optional solution for the indoor unit of the air conditioner is that the indoor unit casing has a split structure, comprising several assembled casing panels;

[0012] The indoor unit housing consists of several shell plates, all of which are made of thermally conductive material.

[0013] Alternatively, among the several shell plates of the indoor unit housing, a portion of the shell plates is a heat-conducting part made of heat-conducting material, while the remaining portion of the shell plates is a resin plate or a plastic plate.

[0014] Furthermore, an optional solution for the indoor unit of the air conditioner is that the surface of the structural components of the indoor unit casing is coated with a coating or covered with a film.

[0015] Furthermore, an optional embodiment of the indoor unit of the air conditioner is that the top and front of the indoor unit casing are provided with heat-conducting parts, so that the top and front of the indoor unit casing are provided with main air inlets.

[0016] Furthermore, an optional embodiment of the indoor unit of the air conditioner is as follows: the back of the indoor unit housing is provided with several densely distributed first auxiliary air inlets, the first auxiliary air inlets are connected to the air cavity and are located near the upper part of the air cavity; the bottom of the indoor unit housing is provided with several second auxiliary air inlets, the back side of the lower part of the air cavity inside the indoor unit housing is provided with an air cavity sidewall, the air cavity sidewall bends and extends toward the air outlet, and the air cavity sidewall is provided with several densely distributed third auxiliary air inlets near the air outlet, the second auxiliary air inlets, the third auxiliary air inlets and the air cavity are connected in sequence.

[0017] Furthermore, an optional embodiment of the air conditioner indoor unit is as follows: the air conditioner indoor unit also includes an air guide plate and air guide blades installed at the air outlet, and the air guide plate and air guide blades are both made of heat-conducting material.

[0018] Furthermore, an optional embodiment of the indoor unit of the air conditioner is that the heat-conducting part of the casing is a thin-walled plate, and the thickness of the heat-conducting part of the casing is no more than 3mm.

[0019] As described above, the air-conditioning indoor unit with air cavity-assisted heat exchange involved in this utility model has the following beneficial effects:

[0020] This application provides a heat-conducting part with excellent thermal conductivity on the indoor unit casing of the air conditioner indoor unit, and a main air inlet is provided on the heat-conducting part. Thus, when the indoor unit is operating in cooling mode, the indoor unit casing has a temperature lower than the indoor air due to the low temperature at the air outlet. Therefore, the temperature of the air entering the air cavity through the main air inlet is higher than the temperature of the heat-conducting part. The air at the main air inlet exchanges heat with the heat-conducting part, preheating the heat-conducting part. The heat-conducting part absorbs heat from the air at the main air inlet and is then heated. The heat-conducting part itself has good thermal conductivity, effectively transferring heat to the entire indoor unit casing, thereby cooling the air entering the air cavity and heating the indoor unit casing. Ultimately, the temperature of the indoor unit casing is higher than the dew point of the air surrounding the air cavity, thus suppressing the formation of condensate. Therefore, this application avoids the need for insulation layers, felt, foam, and other materials in the indoor unit of an air conditioner, and reduces the use of flammable plastics or foam materials, especially given the increasing use of cyclopentane refrigerant, which poses a greater risk due to the presence of flammable foam materials. Thus, this application simplifies the structure and reduces costs while ensuring stable air outlet temperature. It also effectively prevents dust accumulation and mold growth, provides better safety, and improves the energy efficiency of the air conditioner. Furthermore, both the indoor unit casing and the air cavity participate in auxiliary heat exchange, resulting in more uniform air outlet temperature during operation. Attached Figure Description

When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0028] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0029] This application relates to air conditioners, and more particularly to an indoor unit for auxiliary heat exchange in the air cavity of an air conditioner.

[0030] like Figure 1 and Figure 2As shown, the air conditioning indoor unit with air cavity assisted heat exchange involved in this application includes an indoor unit housing 10, a fan assembly 50, and a heat exchanger 60; the indoor unit housing 10 is provided with a main air inlet 20 and an air outlet 30 that are connected inside and out, and the air outlet 30 is located at the lower end of the indoor unit housing 10; an air cavity 40 is provided inside the indoor unit housing 10, and the air cavity 40 connects between the main air inlet 20 and the air outlet 30; an air cavity structure for forming the air cavity 40 is fixed inside the indoor unit housing 10, and the air cavity structure near the front of the air cavity 40 is defined as the first air cavity structure 13, and the air cavity structure near the back of the air cavity 40 is defined as the second air cavity structure 14; the fan assembly 50 and the heat exchanger 60 are both installed in the air cavity 40, and the fan assembly 50 is preferably a cross-flow fan. In particular, as Figures 3 to 6 As shown, at least a portion of the indoor unit casing 10 is a heat-conducting part 11 made of a heat-conducting material, thus the heat-conducting part 11 has good thermal conductivity, and a main air inlet 20 is provided on the heat-conducting part 11. When the indoor unit of the air conditioner is running, under the action of the fan assembly 50, indoor air is drawn into the air cavity 40 through the main air inlet 20. After heat exchange with the heat exchanger 60 in the air cavity 40, the indoor air flows out from the air outlet 30, achieving cooling in cooling mode or heating in heating mode.

[0031] Furthermore, when the indoor unit of the air conditioner is running in cooling mode, the indoor unit casing 10 has a temperature lower than the indoor air due to the low temperature at the air outlet 30. That is, the temperature of the indoor unit casing 10 is lower than the temperature of the indoor air in cooling mode. Therefore, the temperature of the air entering the air cavity 40 at the main air inlet 20 is higher than the temperature of the casing heat-conducting part 11. The air at the main air inlet 20 exchanges heat with the casing heat-conducting part 11. The air entering the air cavity 40 from the main air inlet 20 preheats the casing heat-conducting part 11. The casing heat-conducting part 11 absorbs the heat from the air at the main air inlet 20 and is heated up. The casing heat-conducting part 11 itself has good thermal conductivity, which effectively transfers heat to the entire indoor unit casing 10, and the entire indoor unit casing 10 is heated up. Thus, this application cools the air entering the air cavity 40 and simultaneously heats the indoor unit casing 10. Both the indoor unit casing 10 and the air cavity 40 participate in auxiliary heat exchange, thereby achieving a temperature of the indoor unit casing 10 that is closer to room temperature (or the temperature at the main air inlet 20) and a temperature of the indoor unit casing 10 that is higher than the dew point of the air surrounding the air cavity 40. This suppresses the generation of condensate and overcomes the condensate problem of the air conditioner indoor unit when operating in cooling mode at a low cost.

[0032] Because this application reliably suppresses condensation generation in cooling mode, it eliminates the need for insulation layers, felt, foam, or other structures in the indoor unit to prevent condensation dripping. This reliably avoids the use of flammable plastics or foam materials in the indoor unit, especially given the increasing use of cyclopentane refrigerant, which poses a greater risk due to the presence of flammable foam materials. Thus, this application simplifies the structure and reduces costs while ensuring stable air outlet temperature, effectively preventing dust accumulation and mold growth, and providing better safety. Furthermore, eliminating the need for an insulation layer on the back of the indoor unit improves its appearance and simplifies assembly, preventing large gaps and slits caused by the insulation layer, ultimately improving energy efficiency. Additionally, both the indoor unit casing 10 and the air cavity 40 participate in auxiliary heat exchange, resulting in more uniform air outlet temperature during operation.

[0033] Furthermore, the indoor unit of the air conditioner also includes an air guide plate and air guide blades installed at the air outlet 30, both of which are made of heat-conducting material. The first air cavity structure 13 and the second air cavity structure 14 are also made of heat-conducting material.

[0034] Furthermore, the materials of the housing heat-conducting part 11, the first air cavity structure 13, the second air cavity structure 14, the air guide plate, and the air guide blades are all aluminum alloy, magnesium alloy, iron alloy, or copper, etc., which not only facilitates heat exchange but also strengthens the structure of the indoor unit housing 10. The housing heat-conducting part 11, the first air cavity structure 13, and the second air cavity structure 14 are all thin-walled plates, with a thickness of no more than 3mm. Preferably, the processing methods for the housing heat-conducting part 11, the first air cavity structure 13, the second air cavity structure 14, the air guide plate, and the air guide blades, which are made of metal and have good thermal conductivity, include, but are not limited to, sheet metal, extrusion, stamping, die casting, and machining. Correspondingly, the housing heat-conducting part 11, the first air cavity structure 13, the second air cavity structure 14, the air guide plate, and the air guide blades are all sheet metal parts, or extruded parts, or stamped parts, or die-cast parts, or machined parts.

[0035] Furthermore, such as Figure 3 , Figure 4 and Figure 6As shown, the heat-conducting part 11 of the housing has an expanded area 12. The expanded area 12 increases the surface area of ​​the heat-conducting part 11, improving the heat exchange efficiency between the heat-conducting part 11 and the air at the main air inlet 20, and more reliably controlling the generation of condensate during cooling. Preferably, the expanded area 12 is a grooved structure, increasing the surface area of ​​the heat-conducting part 11 through densely spaced grooves. Alternatively, the expanded area 12 is a corrugated structure, giving the heat-conducting part 11 a corrugated surface at the expanded area 12, further increasing the surface area. Alternatively, the expanded area 12 is a porous honeycomb structure, increasing the surface area of ​​the heat-conducting part 11 through a porous design. In this embodiment, the expanded area 12 is provided at the lower end of the front side of the indoor unit housing 10 (i.e., near the air outlet 30) and the upper end of the back side of the indoor unit housing 10, achieving better heat exchange efficiency and improving the efficiency of auxiliary heat exchange.

[0036] Furthermore, the indoor unit housing 10 can be either an integral structure or a split structure. When the indoor unit housing 10 is an integral structure, the entire indoor unit housing 10 is made of a metal material with good thermal conductivity, such as aluminum alloy, magnesium alloy, iron alloy, or copper, and the entire indoor unit housing 10 constitutes the housing heat-conducting part 11. When the indoor unit housing 10 is a split structure, the indoor unit housing 10 is assembled from several housing plates; in this case, all of the several housing plates of the indoor unit housing 10 are housing heat-conducting parts 11 made of thermally conductive material, and the entire indoor unit housing 10 constitutes the housing heat-conducting part 11; or, among the several housing plates of the indoor unit housing 10, a portion of the housing plates are housing heat-conducting parts 11 made of thermally conductive material, and the remaining portion of the housing plates are resin plates or plastic plates, then the indoor unit housing 10 is composed of materials such as aluminum alloy, magnesium alloy, iron alloy, or copper combined with other resin or plastic materials.

[0037] Preferably, such as Figures 3 to 6 As shown, in this embodiment, the top and front of the indoor unit housing 10 are provided with a housing heat conduction part 11, so that the top and front of the indoor unit housing 10 are provided with a main air inlet 20 that runs through the inside and outside.

[0038] Furthermore, the structural components of the indoor unit housing 10 are coated with a coating or a film. The coating or film can be made of resin or ceramic. The coating or film is used to balance heat exchange and stabilize the temperature of the indoor unit housing 10. The coating or film enhances the aesthetics of the indoor unit housing 10, thereby improving the overall appearance of the air conditioner indoor unit. In particular, the coating or film balances the heat exchange between the indoor unit housing 10 and the air at the main air inlet 20, conducting heat between the suction end and the outlet end of the fan assembly 50. The structural components forming the air cavity 40 in the indoor unit housing 10 contact the suction end and the outlet end of the fan assembly 50, that is, contact the inlet and outlet ends of gases with different temperatures, achieving the purpose of assisting heat exchange. When the fan assembly 50 is working, it preheats or precools the indoor air, resulting in better uniformity of the outlet air temperature and a softer feel. It also controls the generation of condensate during cooling.

[0039] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, the back of the indoor unit housing 10 is provided with several densely distributed first auxiliary air inlets 70. The first auxiliary air inlets 70 are through holes that run through the inside and outside. The first auxiliary air inlets 70 are connected to the air cavity 40 and are located near the upper part of the air cavity 40 to improve the heat exchange efficiency between the upper part of the indoor unit housing 10 and the air.

[0040] Furthermore, such as Figures 1 to 4 As shown, the bottom of the indoor unit housing 10 is a flat plate structure with several second auxiliary air inlets 80 spaced apart on the left and right. The second auxiliary air inlets 80 are through holes that run through the inside and outside. The indoor unit housing 10 has an air cavity sidewall 90 on the back side of the lower section of the air cavity 40. The air cavity sidewall 90 is part of the second air cavity structure 14. The air cavity sidewall 90 bends downward toward the air outlet 30. Several densely distributed and through third auxiliary air inlets 91 are opened on the air cavity sidewall 90 near the air outlet 30. The second auxiliary air inlets 80, the third auxiliary air inlets 91 and the air cavity 40 are connected in sequence. Utilizing the Bernoulli effect, indoor air is drawn in at the second auxiliary air inlet 80. The indoor air then enters the air cavity 40 near the air outlet 30 through the third auxiliary air inlet 91. The cooled indoor air is premixed with the hot air (heating mode) or cold air (cooling mode) at the air outlet 30 to achieve better preheating and precooling, making the air temperature and humidity at the air outlet 30 of the air conditioner more stable and providing a better user experience.

[0041] In summary, this application uses a metal plate with good thermal conductivity for the indoor unit casing 10, or a combination of metal plate with metal sheets, metal film, metal mesh, plastic and coating, to efficiently exchange heat with the periphery of the main air inlet 20 and the air cavity 40 near the air outlet 30. This can suppress the generation of condensate in the cooling mode and preheat or precool the air at the air outlet 30, achieving greater heat exchange power with the same indoor unit volume and reducing the size of the air conditioner with the same power.

[0042] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
