Description

Technical Field

[0001] This invention belongs to the field of air conditioning, specifically relating to evaporator components, air conditioners, and control methods. Background Technology

[0002] like Figure 1 As shown in the figure, the layout of the three-stage evaporator in the indoor unit of the existing air conditioner includes a first-stage evaporator 1, a second-stage evaporator 4, and a third-stage evaporator 5. The heating element 2 is installed in the triangular area formed by the first-stage evaporator 1, the second-stage evaporator 4, and the cross-flow fan 3. In the cooling mode of the air conditioner, the evaporator cools the air entering the indoor unit and then discharges it. The heating element is located on the air outlet path of the first-stage evaporator 1 and the second-stage evaporator 4. Due to the different outlet air temperatures at different locations of the evaporator, condensation will form around the heating element due to the interaction of hot and cold air. The condensation drips down onto the cross-flow fan 3 or is directly discharged from the exhaust vent of the indoor unit, which is the phenomenon of water blowing.

[0003] To address the aforementioned issues, the current main solutions involve adjusting and optimizing the shape and installation position of the heating element 2, or using relevant technical means to adjust the uniformity of the evaporator outlet air temperature. However, it is difficult to completely avoid temperature unevenness when the compressor frequency changes. Furthermore, because the heating element 2 is located in the area between the evaporator and the cross-flow fan 3, the proximity between them is limited by the overall structural space of the indoor unit. This may affect the cross-flow fan 3 during heating. Additionally, the heating element 2 is located on the evaporator's outlet air path, requiring the air to pass through the evaporator before reaching the heating element 2, which creates air resistance, affecting airflow and generating noise. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an evaporator assembly, an air conditioner and a control method to solve the problems of water blowing and air resistance caused by the heating tube being installed on the air outlet path of the evaporator.

[0005] According to embodiments of the present invention, the present invention adopts the following technical solution:

[0006] An evaporator assembly includes at least two evaporator sections. The joints are located between adjacent evaporator ends and between the evaporator ends and the air conditioner housing. At least one joint is provided with an air inlet channel. An electric auxiliary heating element is installed in the air inlet channel. The air inlet end of the air inlet channel is provided with a baffle that can close the air inlet end. The baffle has a closed state that completely closes the air inlet channel and an open state that opens the air inlet channel. When the baffle is in the closed state, air passes only through the evaporator. When the baffle is in the open state, air passes through both the evaporator and the air inlet channel.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. Set up an air inlet channel at the joint between adjacent evaporators and place the electric auxiliary heating element in the air inlet channel. When the baffle is in the open state, the air in the air inlet channel can flow through the electric auxiliary heating element, while the air flowing through the evaporator will not flow through the electric auxiliary heating element again.

[0009] This design significantly reduces the amount of airflow passing through the electric auxiliary heating element in cooling mode, thereby minimizing condensation. It also allows for a larger installation position of the electric auxiliary heating element compared to existing technologies, increasing the distance between it and the cross-flow fan, reducing its impact on the fan. Furthermore, the absence of secondary airflow reduces wind resistance and noise. In heating mode, the airflow through the electric auxiliary heating element bypasses the evaporator, resulting in a larger airflow and better heating performance.

[0010] 2. When the baffle is open, the outside air can directly enter the air conditioner through the air intake duct and be exhausted. Compared with entering the air conditioner through the evaporator, the air duct resistance is small, which is suitable for the air supply mode of the air conditioner and can increase the air supply volume without changing the power consumption.

[0011] Furthermore, the baffle is connected to a rotating shaft, and the baffle is set to swing around the axis of the rotating shaft as the swing center.

[0012] Furthermore, the end of the evaporator located on the air inlet channel side is provided with a seal, which is used to abut against the end of the baffle to form a seal.

[0013] Furthermore, when the baffle is in the closed state, an angle α is formed between the baffle and the horizontal plane, and α≠0° or α≠180°.

[0014] Furthermore, both sides of the electric auxiliary heating element are provided with guide parts, which are inclined, and the side of the guide part facing the air inlet end of the air inlet channel is inclined towards the axis of the air inlet channel.

[0015] Furthermore, the distance between the electric auxiliary heating element and the baffle is d1, where d1 ≥ 10 mm; the distance between the electric auxiliary heating element and the evaporator is d2, where d2 ≥ 5 mm.

[0016] Furthermore, a temperature sensor is installed inside the air intake duct to detect the temperature of the air after it has been heated by the electric auxiliary heating element.

[0017] Furthermore, when the electric auxiliary heating element is located above one section of the evaporator, the projection of the lower end or lowest point of the electric auxiliary heating element is located within the end of the evaporator.

[0018] According to embodiments of the present invention, the present invention also employs the following technical solutions:

[0019] An air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes a casing and an evaporator assembly. The casing has an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. A cross-flow fan is installed in the air duct, and the evaporator assembly is also installed in the air duct. The air in the air duct passes through the evaporator assembly and the cross-flow fan in sequence before being discharged.

[0020] According to embodiments of the present invention, the present invention also employs the following technical solutions:

[0021] Control methods, applied to evaporator components, or applied to air conditioners;

[0022] In cooling, heating, and ventilation modes, adjust the baffle to be open or closed according to the indoor temperature requirements. When the baffle is open, adjust the opening angle of the baffle.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In existing technologies, to improve user comfort in cooling mode, a diversion area is set up in the air conditioning duct to mix the air in the diversion area with the cold air in the duct, thereby increasing the outlet air temperature and preventing direct cold air blowing. However, this structure is relatively complex and requires an additional diversion fan structure. Based on the structural setup and control method of this solution, in cooling mode, the outlet air temperature of the duct can be adjusted by opening a baffle, ensuring that the temperature blowing onto the human body is not too low and without affecting the original efficiency of the duct.

[0025] 2. In the air supply mode, the baffle is open, and the external air can directly enter the air duct through the air inlet channel. Compared with entering the air duct through the evaporator, the air duct resistance is small, and the air supply volume can be increased without changing the power consumption.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments are given.

[0039] In a first aspect, embodiments of the present invention disclose an evaporator assembly, specifically including the following embodiments:

[0040] like Figure 2 , Figure 5 As shown, the evaporator assembly includes at least two evaporator sections. The joints 12 are located between the ends of adjacent evaporators and between the ends of the evaporators and the housing 6 of the air conditioner. At least one joint 12 is provided with an air inlet channel 10. An electric auxiliary heating element 11 is installed in the air inlet channel 10. In actual design, the electric auxiliary heating element 11 can be a conventional structure that can achieve electric heating, such as an electric heating tube, an electric heating plate, or an electric heating rod.

[0041] The air inlet duct 10 is provided with a baffle 9 that can close the air inlet end. The baffle 9 has a closed state that completely closes the air inlet duct 10 and an open state that opens the air inlet duct 10. When the baffle 9 is in the closed state, the air only passes through the evaporator. When the baffle 9 is in the open state, the air passes through the evaporator and the air inlet duct 10 at the same time.

[0042] Specifically, two design methods for baffle 9 are given below:

[0043] A. Combination Figure 3 As shown, the baffle 9 is connected to the rotating shaft 13. The baffle 9 swings with the axis of the rotating shaft 13 as the swing center. In the actual design process, the rotating shaft 13 is driven to rotate by a motor or micro motor to drive the baffle 9 to swing. The angle of the swing of the baffle 9 can be controlled according to the requirements, thereby controlling the angle at which the baffle 9 opens the air inlet channel 10.

[0044] B. The baffle 9 is slidably mounted at the air inlet end of the air inlet channel 10. In actual design, the baffle 9 is controlled by a micro cylinder. The sliding direction of the baffle 9 is not limited, as long as the baffle 9 can open the air inlet channel 10. Figure 4 As shown, the air inlet channel 10 is vertical, so the sliding direction of the baffle 9 can be vertical, horizontal or diagonal, all of which can achieve the purpose of opening the air inlet channel 10.

[0045] You can choose either design method A or design method B according to the actual situation. In the following examples, design method A will be used as an example for illustration.

[0046] In another embodiment of the present invention, the evaporator is provided with three sections, including a first evaporator 1 arranged in a triangular pattern, a second evaporator 4, and a third evaporator 5 arranged vertically. In actual design, the third evaporator 5 is not required to be completely vertical and can be slightly tilted. Of course, all evaporators can be arranged according to the actual space layout. This embodiment only provides one example. The air inlet channel 10 then has the following four design methods:

[0047] C. For example Figure 3 As shown, the air inlet channel 10 is located between the first evaporator 1 and the second evaporator 4. The air inlet channel 10 is vertical, and the baffle 9 is located at the upper end of the air inlet channel 10. In actual design, the axis of the air inlet channel 10 is not required to be vertical; it can also be inclined, depending on the space design between the first evaporator 1 and the second evaporator 4.

[0048] D. If the air inlet channel 10 is located between the second evaporator 4 and the third evaporator 5, then the air inlet channel 10 is horizontal, and the baffle 9 is located at the right end of the air inlet channel 10 (see...). Figure 6 (as shown in the direction). In actual design, the axis of the air inlet channel 10 is not required to be horizontal, and can also be inclined, depending on the space design between the second evaporator 4 and the third evaporator 5.

[0049] E. The air inlet channel 10 is located between the end of the first evaporator 1 and the shell 5, and the baffle 9 is located between the end of the first evaporator 1 and the shell 6. See Figure 8 , Figure 9 As shown.

[0050] F. The air inlet channel 10 is located between the end of the third-stage evaporator 5 and the shell 6, and the baffle 9 is located between the lower end of the third-stage evaporator 1 and the shell 6. See Figure 10 , Figure 11 As shown.

[0051] Design method C, D, E, or F can be selected according to the actual situation, or these design methods can be combined arbitrarily, that is, air inlet channels 10 can be set at any two, three, or four joints 12. In actual design, the evaporator can also be set with only two sections or more sections, and the design of the air inlet channel 10 can also be carried out in various ways with reference to the design method in this embodiment.

[0052] Based on design method D, when the electric auxiliary heating element 11 is located above one section of the evaporator, the projection of the lower end or lowest point of the electric auxiliary heating element 11 lies within the end of that evaporator. Specifically, in conjunction with... Figure 6 As shown, the electric auxiliary heating element 11 is located above the third evaporator 5, and the projection of the lower end of the electric auxiliary heating element 11 is located inside the upper end of the third evaporator 5. With this design, even if there is a condensation effect on the electric auxiliary heating element 11, the water passing through the electric auxiliary heating element 11 will fall downward into the third evaporator 5, and will not cause a water blowing phenomenon.

[0053] In another embodiment of the invention, combined with Figure 3 As shown, the end of the evaporator located on one side of the air inlet channel 10 is provided with a sealing element 14. The sealing element 14 is used to abut against the end of the baffle 9 to form a seal. Specifically, the sealing element 14 can be a flexible plastic film (plastic roll, rubber, etc.) fixed to the end of the evaporator. When the end of the baffle 9 abuts against the sealing element 14, a seal can be achieved. By setting the sealing element 14, when the baffle 9 is in the closed state, the noise caused by air entering through the gap at both ends of the baffle 9 is reduced.

[0054] In another embodiment of the invention, when the baffle 9 is in the closed state, an angle α is formed between the baffle 9 and the horizontal plane, and α ≠ 0° or α ≠ 180°. That is, the baffle 9 is not horizontally set, thereby preventing water droplets from dripping downwards when condensation occurs on the baffle 9. When the baffle 9 is tilted, water droplets will enter the evaporator located at the lower end of the baffle 9 along the tilted surface of the baffle 9. Especially based on design method C, such as Figure 3 As shown, the right end of the baffle 9 is tilted downwards, so the water droplets on the baffle 9 can be guided into the second evaporator 4 and discharged.

[0055] In another embodiment of the invention, combined with Figure 4 , Figure 6 As shown, the electric auxiliary heating element 11 has guide portions 15 on both sides. The guide portions 15 are inclined, and the side of the guide portion 15 facing the air inlet end of the air inlet channel 10 is inclined towards the axis of the air inlet channel 10. The arrangement of the guide portions 15 makes the air flow into the air inlet channel 10 smoother, as detailed below:

[0056] Based on design method C, such as Figure 4 As shown, the cross-section of the electric auxiliary heating element 11 is triangular, and the three corners of the electric auxiliary heating element 11 are all arc-shaped. The guide parts 15 on both sides are parallel to the sides of the first evaporator 1 and the second evaporator 4, respectively. When the baffle 9 is in the open state, the air enters from the upper end of the air inlet channel 10 and can enter along the guide parts 15.

[0057] Based on design method D, such as Figure 6 As shown, the cross-section of the electric auxiliary heating element 11 is trapezoidal, and an extension is provided on one side of the long side of the trapezoid. However, the projection of the lower end of the extension is located in the third section of the evaporator 5 below it.

[0058] In another embodiment of the present invention, the distance between the electric auxiliary heating element 11 and the baffle 9 is d1, where d1 ≥ 10 mm. The distance between the electric auxiliary heating element 11 and the evaporator is d2, where d2 ≥ 5 mm. By setting the distance between the electric auxiliary heating element 11 and the baffle 9 and the evaporator, the influence of the electric auxiliary heating element 11 on the baffle 9 and the evaporator during heating is reduced.

[0059] In another embodiment of the invention, combined with Figure 2 As shown, a temperature sensor 16 is installed inside the air inlet channel 10. The temperature sensor 16 is used to detect the temperature of the air after it has been heated by the electric auxiliary heater 11. Specifically, the temperature sensor 16 can be any existing temperature sensor. By detecting the temperature inside the air inlet channel 10, the heating effect of the electric auxiliary heater 11 can be determined. This allows the user to choose to increase the power of the electric auxiliary heater 11 or adjust the angle of the baffle 9. For example, in heating mode, when the electric auxiliary heater 11 needs to be turned on, the air entering from the air inlet channel 10 is heated by the electric auxiliary heater 11 and then discharged. If the temperature detected by the temperature sensor 16 is low, it means that the power of the electric auxiliary heater 11 is low and cannot effectively heat the incoming air. In this case, the angle of the baffle 9 can be adjusted to reduce the opening angle range of the air inlet channel 10, thereby reducing the amount of air entering the air inlet channel 10 and decreasing the amount of air that needs to be heated by the electric auxiliary heater 11, thus increasing the air temperature.

[0060] In the actual design process, the temperature sensor 16 can be connected to the air conditioning control system, which makes it easier to adjust the angle of the baffle 9.

[0061] Secondly, embodiments of the present invention disclose an air conditioner, specifically including the following embodiments:

[0062] Combination Figure 2 , Figure 5 As shown, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes a housing 6 and an evaporator assembly as described in any of the above embodiments. The housing 6 has an air inlet 7 and an air outlet 8. An air duct is formed between the air inlet 7 and the air outlet 8. A cross-flow fan 3 is installed in the air duct. The evaporator assembly is also installed in the air duct. The air in the air duct passes through the evaporator assembly and the cross-flow fan 3 in sequence before being discharged.

[0063] by Figure 2 Taking the direction shown in the figure as an example, the air inlet 7 is at the upper end of the housing 6, and the air outlet 8 is at the lower end of the housing 6. The specific structural settings of the air inlet 7 and the air outlet 8 can be designed with reference to the indoor unit in the existing technology, that is, the air in the duct flows from top to bottom.

[0064] Based on design method D, since the air inlet duct 10 is designed on the side and the air inlet 7 is on top, in order to allow the air to enter the air inlet duct 10 more smoothly, the rotating shaft 13 is set near the bottom of the baffle 9. The baffle 9 is swung clockwise, so that the upper end of the baffle 9 swings to form a... Figure 7 In the state shown, the air entering from the upper air inlet 7 can be more smoothly guided into the air intake channel 10.

[0065] Based on design method E, since the layout of the first evaporator 1 is such that the left end is inclined downwards, the baffle 9 is also inclined and is in the closed state. Figure 9 When the dashed line represents the closed state of baffle 9, the right end of baffle 9 presses against the side of the first evaporator 1. With the air inlet 7 at the top, to ensure smoother airflow into the air inlet channel 10, the rotating shaft 13 is mounted on the left side of the housing 6. Rotating baffle 9 counterclockwise will open it, with the baffle 9 in the open state near the housing 6. Figure 9 As shown, it will not obstruct airflow into the air inlet channel 10. In this embodiment, the seal 14 is L-shaped and covers the corner of the end of the first evaporator 1.

[0066] Based on design method F, the right end of baffle 9 is hinged to housing 6, and baffle 9 is in the closed state. Figure 11 When the baffle 9 is in the closed state (the dotted line represents the baffle), the left end of the baffle 9 rests against the lower end of the third-stage evaporator 5. When the baffle 9 is in the open state, the left end of the baffle 9 tilts downwards. Figure 11As shown, it has a guiding effect on the airflow, causing the air entering from above to flow to the left after entering the air intake channel 10. In this embodiment, the seal 14 is L-shaped and covers the corner of the end of the third evaporator 5.

[0067] In the actual design process, the distance between the electric auxiliary heating element 11 and the shell 6 is greater than 10mm to avoid heat from affecting and damaging the shell 6.

[0068] Thirdly, embodiments of the present invention disclose a control method, specifically including the following embodiments:

[0069] The control method is applied to the evaporator assembly as described in any of the above embodiments, or to the air conditioner as described in the above embodiments. In cooling, heating, and air supply modes, the baffle 9 is adjusted to be in an open or closed state according to the indoor temperature requirement. When the baffle 9 is in the open state, the opening angle of the baffle 9 is adjusted.

[0070] Specifically, in heating mode, the baffle 9 is adjusted to be open or closed according to the indoor temperature. When the evaporator can sufficiently heat the air to meet the heating demand, the baffle 9 does not need to be opened. When the baffle 9 is open, the opening angle of the baffle 9 is adjusted according to the temperature detected by the temperature sensor 16.

[0071] In cooling mode, after the indoor temperature reaches the preset temperature for 15-30 minutes, adjust the baffle 9 to open, so that the air in the air inlet channel 10 and the air in the duct mix, adjust the air outlet temperature of the duct, so that the temperature blown on the human body is not too low, and the original efficiency of the duct is not affected.

[0072] When the indoor temperature rises above the preset temperature for a period of time, specifically, when the indoor temperature rises above the preset temperature by 1°C and lasts for 5 minutes, the baffle 9 is turned off. At this time, the air is only blown out after being cooled by the evaporator, which lowers the indoor temperature again.

[0073] In the air supply mode, with the baffle 9 in the open position, external air can directly enter the air duct through the air inlet channel 10. Compared to entering the air duct through the evaporator, the air duct resistance is small, and the air supply volume can be increased without changing the power consumption.

[0074] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
