Description

Technical Field

[0002] With the development of society and the continuous improvement of people's living standards, various air-conditioning devices have become one of the indispensable electrical appliances in people's daily lives. Various air-conditioning devices can help people reach an adaptable temperature when the environmental temperature is too high or too low. Currently, the air-conditioning devices mainly include various types of air conditioners and fans.

[0003] Among them, the air conditioners can be divided into floor-standing, wall-mounted, ceiling-mounted, etc. according to the different settings of the indoor units. The indoor unit of the floor-standing air conditioner is mainly used in places with large areas such as living rooms, schools, hospitals, etc., and can quickly provide more cooling or heating capacity to these places, so that the environmental temperature can meet the comfort requirements of users as soon as possible. However, the heat exchanger of the existing indoor unit of the floor-standing air conditioner often uses the heat exchanger tray component as the main support of the heat exchanger, and the air inlet grille is generally designed with separate components such as a filter screen track, resulting in a large number of components, many installation overlapping surfaces, and it is difficult to effectively control the problem of thermal expansion and contraction noise. If the air inlet grille is integrated, due to the problem formed by the ejection lifter of the mold, the filter screen track structure cannot be made. In addition, the distance between the air inlet grille and the heat exchanger of the existing indoor unit of the floor-standing air conditioner is relatively close, and there is often a risk that the air inlet grille is deformed and touches the heat exchanger when transported and dropped. Moreover, the internal components, such as the elbow part of the heat exchanger, can often be seen through the air inlet grille from the rear of the indoor unit of the floor-standing air conditioner, affecting the visual effect of the whole machine. Summary of the Invention

[0004] An object of the present invention is to effectively slow down the transportation impact and avoid the risk of deformation of the elbow of the heat exchanger caused by transportation and dropping by arranging a baffle between the heat exchanger and the air inlet grille.

[0005] A further object of the present invention is to achieve the integration of the air inlet grille while taking into account the support strength, and the baffle structure realizes the function of the filter screen track.

[0017] Furthermore, for the indoor unit of the vertical air conditioner of the present invention, the air inlet grille includes a main body portion and support portions on the left and right sides of the main body portion.

[0018] Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more clear about the above and other objects, advantages and features of the present invention. Brief Description of the Drawings

[0019] Some specific embodiments of the present invention will be described in detail hereinafter with reference to the drawings in an exemplary but not limiting manner. The same reference numerals in the drawings denote the same or similar components or parts. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0022] Figure 3 is a cross-sectional view of an indoor unit of a vertical air conditioner according to an embodiment of the present invention. Detailed Description of the Embodiments

[0023] This embodiment provides an indoor unit of a vertical air conditioner. By arranging a baffle between the heat exchanger and the air inlet grille, the transportation impact can be effectively reduced, and it can be avoided that the deformation of the air inlet grille caused by transportation drop collides with the heat exchanger, thereby ensuring the working reliability of the indoor unit of the vertical air conditioner and improving the user experience. Figure 1 is a front view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention, Figure 2 is a side view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention, Figure 3 is a cross-sectional view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. As Figures 1 to 3 shown, the indoor unit 100 of the air conditioner in this embodiment generally may include: a housing 110, a heat exchanger 120, and a baffle 140.

[0024] Wherein, a cavity 111 is defined inside the housing 110, and the housing 110 includes an air inlet grille 115. The heat exchanger 120 may be disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111. The baffle 140 may be disposed between the heat exchanger 120 and the air inlet grille 115 and configured to fix the heat exchanger 120 and the air inlet grille 115 and act as a buffer.

[0025] As mentioned above, the distance between the air inlet grille and the heat exchanger of the current vertical air conditioner indoor unit is relatively close. If it drops during transportation, there is often a risk that the air inlet grille deforms and touches the heat exchanger. The vertical air conditioner indoor unit 100 of this embodiment can effectively reduce the transportation impact by arranging a baffle 140 between the heat exchanger 120 and the air inlet grille 115, and can avoid the collision between the deformed air inlet grille 115 and the heat exchanger 120 caused by transportation drops, ensuring the working reliability of the vertical air conditioner indoor unit 100 and improving the user experience.

[0026] It should be noted that the vertical air conditioner indoor unit 100 in this embodiment, as a type of split air conditioner, can be widely used in places such as homes and offices. The vertical air conditioner indoor unit 100 has advantages such as large power and strong wind force compared with the wall-mounted air conditioner indoor unit, and the price starting point is relatively higher. The vertical air conditioner indoor unit 100 is usually suitable for indoor environments with a relatively large area. For example, if the living room area is relatively large, it is best to choose the vertical air conditioner indoor unit 100 to ensure good cooling, heating, and air supply effects.

[0027] However, the air inlet grille of the existing vertical air conditioner indoor unit is generally designed with separate components such as filter tracks, resulting in a large number of components, many installation lapping surfaces, and difficult effective control of the thermal expansion and contraction volume problems. The vertical air conditioner indoor unit 100 of this embodiment can well solve the above problems through a unique structural setting. In a specific embodiment, as Figure 3 shown, the air inlet grille 115 can include a main body portion 151 and support portions 152 on both the left and right sides of the main body portion 151. That is to say, the main body portion 151 and the support portions 152 on both the left and right sides of the main body portion 151 are integrally formed as the air inlet grille 115, realizing the integration of the air inlet grille 115, reducing components and optimizing the structure.

[0028] In a preferred embodiment, the main body portion 151 and the support portions 152 on both the left and right sides of the main body portion 151 can both be made of plastic material, that is, the entire air inlet grille 115 is made of plastic material. Compared with the traditional air inlet grille with two sheet metal columns on the left and right for column support, the main body portion 151 and the support portions 152 on both the left and right sides of the main body portion 151 in this embodiment are made of the same plastic material, which is convenient for realizing the integration of the air inlet grille 115 and taking into account the support strength at the same time.

[0029] In addition, the baffle 140 may have a flat plate portion 141 near the side of the air inlet grille 115 and a convex portion 142 near the side of the heat exchanger 120. In a specific embodiment, the heat exchanger 120 is V-shaped and bent backward. And, the heat exchanger 120 may include a tube sheet 121 and elbows 122 at both ends of the tube sheet 121. The convex portion 142 is fixed to the tube sheet 121, and the front end of the flat plate portion 141 is fixed to the support portion 152 on the right side. Since both the convex portion 142 and the flat plate portion 141 are part of the baffle 140, and the convex portion 142 is fixed to the tube sheet 121, in fact, the baffle 140 is fixed to the heat exchanger 120; the front end of the flat plate portion 141 is fixed to the support portion 152 on the right side, in fact, the baffle 140 is fixed to the air inlet grille 115. That is to say, the baffle 140 is fixed to the heat exchanger 120 and the air inlet grille 115 respectively, so that the heat exchanger 120 and the air inlet grille 115 are indirectly fixed together.

[0030] For the indoor unit 100 of the vertical air conditioner in this embodiment, considering the optimal utilization efficiency of the heat exchanger 120, the elbows 122 of the heat exchanger 120 are relatively close to the air inlet grille 115 on the right side, and there is a risk that the air inlet grille 115 is deformed and touches the elbows 122 during transportation and dropping. That is to say, setting the baffle 140 between the heat exchanger 120 and the air inlet grille 115 to achieve the function of buffering during dropping actually avoids the collision between the elbows 122 of the heat exchanger 120 and the air inlet grille 115, resulting in component damage, and effectively reduces various impacts during the transportation process.

[0031] The indoor unit 100 of the vertical air conditioner may further include: a filter screen (not shown in the figure), which is arranged at the air inlet grille 115 and is configured to perform primary filtration on the air entering the cavity 111. And, the baffle 140 is also configured to: serve as a track for the filter screen, so that the filter screen can slide in and be installed. Due to the problem formed by the ejection lifter of the mold, the integrated air inlet grille 115 cannot be made into a filter screen track structure. Therefore, it is very important that the baffle 140 in this embodiment serves as a track for the filter screen, which can enable the filter screen to slide in and be installed.

[0032] In addition, usually, the internal components can be seen through the air inlet grille from the rear of the current indoor unit of the vertical air conditioner, such as the elbow part of the heat exchanger, which affects the overall visual effect of the whole machine. The baffle 140 of the indoor unit 100 of the vertical air conditioner in this embodiment can also be configured to: serve as an object to block the elbows 122, so as to avoid seeing the elbows 122 from behind the air inlet grille 115. That is to say, for the indoor unit 100 of the vertical air conditioner in this embodiment, by setting the baffle 140, a single component can achieve multiple functions, effectively simplifying the structure of the indoor unit 100 of the vertical air conditioner and effectively improving the overall visual effect of the indoor unit 100 of the vertical air conditioner.

[0033] The heat exchanger of the existing vertical air conditioner indoor unit often uses the heat exchanger tray component as the main support of the heat exchanger. The vertical air conditioner indoor unit 100 of this embodiment may further include: an air duct assembly 150, disposed at the rear side of the heat exchanger 120 and configured to fix the heat exchanger 120 to the air inlet grille 115. That is to say, the vertical air conditioner indoor unit 100 of this embodiment does not need to additionally provide a tray component to support the heat exchanger 120, but uses the air duct assembly 150 that originally needs to be provided to realize the fixation of the heat exchanger 120, further reducing the number of components and simplifying the structure.

[0034] It should be emphasized that the air duct assembly 150 can fix the heat exchanger 120 to the air inlet grille 115, and as mentioned above, the baffle 140 can indirectly fix the heat exchanger 120 and the air inlet grille 115 together. Through the air duct assembly 150 and the baffle 140, double fixation of the heat exchanger 120 and the air inlet grille 115 is achieved, effectively playing a strengthening role, improving the connection stability, and further reducing the risks of collision and impact that may occur during transportation and dropping.

[0035] In a specific embodiment, the housing 110 may further include: a front door panel 112, and the front door panel 112 is connected to the air inlet grille 115. An air inlet 116 is provided on the air inlet grille 115 and configured to allow the air in the indoor environment to enter the cavity 111 through the air inlet 116. In fact, the housing 110 may include a front door panel 112 and a rear panel 119, and the air inlet grille 115 may be provided on the rear panel 119. The filter provided at the air inlet 116 of the air inlet grille 115 can preliminarily filter the air entering the cavity 111 through the air inlet 116, improving the cleanliness of the interior of the vertical air conditioner indoor unit 100 and the finally discharged air.

[0036] In addition, the housing 110 may further include panels such as a top panel and a bottom panel. The setting of the top panel and the bottom panel can make the overall integrity of the vertical air conditioner indoor unit 100 better and make the vertical air conditioner indoor unit 100 more stable when installed in the indoor environment. The front door panel 112 and the rear panel 119 of the vertical air conditioner indoor unit 100 of this embodiment can be directly connected without additionally providing side panels. In some other embodiments, the housing 110 may further include side panels, and the side panels may include a left side panel and a right side panel, which are respectively connected to the front door panel 112 and the rear panel 119.

[0037] In a preferred embodiment, the housing 110 of the vertical air conditioner indoor unit 100 may further include a front scroll tongue 114 and a rear scroll tongue 113, and an air outlet 117 is formed between the front scroll tongue 114 and the rear scroll tongue 113. The front end of the front scroll tongue 114 is connected to the front door panel 112, and the front end of the rear scroll tongue 113 is also connected to the front door panel 112. The formation of the air outlet 117 between the front scroll tongue 114 and the rear scroll tongue 113 can also be reflected on the front door panel 112. One end of the heat exchanger 120 can be close to the front door panel 112 on the side of the front scroll tongue 114, and the other end can be located behind the rear scroll tongue 113.

[0038] As mentioned above, the heat exchanger 120 is disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111. When the vertical air conditioner indoor unit 100 operates in the cooling mode, the air heated by the heat exchanger 120 is cold air, and after being sent to the indoor environment through the air outlet 117, the temperature of the indoor environment can be reduced, making the user feel cool. When the vertical air conditioner indoor unit 100 operates in the heating mode, the air heated by the heat exchanger 120 is hot air, and after being sent to the indoor environment through the air outlet 117, the temperature of the indoor environment can be increased, making the user feel warm.

[0039] In a specific embodiment, the vertical air conditioner indoor unit 100 can turn on the cooling mode or the heating mode after receiving the user's turn-on trigger signal. More specifically, it can receive the turn-on trigger signal sent by the user through the display device, voice device, remote control of the vertical air conditioner indoor unit 100, or the mobile terminal bound to the vertical air conditioner indoor unit 100. The mobile terminal can be a portable intelligent device, such as a smart phone, a tablet computer, etc.

[0040] The heat exchanger 120 can be disposed at a position in the cavity 111 close to the air inlet 116, and the shape of the heat exchanger 120 can be matched with the air inlet 116, so that the air entering the cavity 111 through the air inlet 116 can be completely exchanged heat by the heat exchanger 120, improving the heat exchange efficiency. Specifically, the heat exchanger 120 of the vertical air conditioner indoor unit 100 in this embodiment can be V-shaped and bent backward. The V-shaped heat exchanger 120 can effectively increase the heat exchange area and improve the heat exchange efficiency.

[0041] In addition, a blower fan 130 may be disposed in the cavity 111 inside the housing 110, in front of the heat exchanger 120. The blower fan 130 can send the air heated by the heat exchanger 120 to the indoor environment through the air outlet 117. The fans of the vertical air conditioner indoor unit 100 mainly include three types: centrifugal, cross-flow, and axial-flow. Among them, the air inside the centrifugal fan is affected by the centrifugal force, generating a vacuum degree in the center of the impeller. The inhaled air turns 90° at the impeller inlet and then enters the flow channel formed by the blades, obtaining kinetic energy and pressure energy under the action of the blades. The airflow discharged from the blade channel enters the volute, and after concentration and diversion, it is discharged from the outlet of the centrifugal fan.

[0042] The cross-flow fan can also be called a tubular fan. The airflows radially enter the blade grid from the open part of the impeller, pass through the inside of the impeller, and are discharged into the volute from the other blade grid, forming the working airflows. The airflows in the axial-flow fan flow axially inside the impeller. Each of the above three types of fans has its own advantages and disadvantages and can be set according to the actual situation. However, no matter which type of fan is used, it can send the air heated by the heat exchanger 120 to the indoor environment through the air outlet 117 to adjust the temperature of the indoor environment.

[0043] The blower fan 130 may also be correspondingly provided with a motor configured to drive the blower fan 130 to rotate. And the air supply speed of the vertical air conditioner indoor unit 100 can be adjusted by adjusting the rotation speed of the motor driving the blower fan 130. In a preferred embodiment, the blower fan 130 may be a tubular fan. This is because the axial length of the tubular fan is not restricted, and the length of the impeller can be arbitrarily selected according to different usage requirements. Moreover, the airflows pass through the impeller, being affected by the force of the blades twice, so the airflows can reach a long distance and the air supply is relatively far. In addition, the tubular fan has no turbulent flow, the air outlet is uniform, and the noise is low, which can effectively improve the user experience.

[0044] In a specific embodiment, a horizontal swing blade (not shown in the figure) and a vertical swing blade 118 may also be provided at the air outlet 117. The vertical swing blade 118 can be configured to adjust the left-right air supply direction at the air outlet 117, and the horizontal swing blade can be configured to adjust the up-down air supply direction at the air outlet 117. In a specific embodiment, the horizontal swing blade and the vertical swing blade 118 are configured to adjust the specific posture according to the air supply mode. For example, the air supply mode may include a variety of different air supply instructions, and the horizontal swing blade and the vertical swing blade 118 can adjust the specific posture according to different air supply instructions.

[0045] More specifically, the specific postures of the vertical swing blades 118 may include facing left, facing middle, and facing right. The specific postures of the horizontal swing blades include facing up, facing middle, and facing down. In a preferred embodiment, the horizontal swing blades and the vertical swing blades 118 can also adjust the specific angle of the air outlet to achieve different air volumes. For example, even when facing left, the air outlet angles of the vertical swing blades 118 can be different. Even when facing up, the air outlet angles of the horizontal swing blades can be different.

[0046] Regarding the specific postures of the horizontal swing blades, it should be noted that when the horizontal swing blades face up, the indoor unit 100 of the floor-standing air conditioner realizes upward air outlet, which is more suitable for the situation where the indoor unit 100 of the floor-standing air conditioner operates in the cooling mode. Since the cold air is sent out by the indoor unit 100 of the floor-standing air conditioner in the cooling mode, according to the characteristics of the cold air, it will gradually sink after being blown upward, so that the temperature of the entire indoor environment can be reduced. The prevention of direct blowing of cold air can also effectively avoid situations such as headaches and colds for users.

[0047] When the horizontal swing blades face down, the indoor unit 100 of the floor-standing air conditioner realizes downward air outlet, which is more suitable for the situation where the indoor unit 100 of the floor-standing air conditioner operates in the heating mode. Since the hot air is sent out by the indoor unit 100 of the floor-standing air conditioner in the heating mode, according to the characteristics of the hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. Blowing the hot air downward can also blow more effectively towards the user, making the user feel warm and comfortable.

[0048] In addition, an air outlet deflector (not shown in the figure) can be provided at the air outlet 117, configured to open and close the air outlet 117. When the air outlet deflector opens the air outlet 117, the air guided by the horizontal swing blades and the vertical swing blades can be sent to the indoor environment. If the air outlet deflector closes the air outlet 117, no air will blow out at the air outlet 117. Generally, when the indoor unit 100 of the floor-standing air conditioner is turned off, the air outlet deflector can close the air outlet 117 to prevent external dust from entering the inside of the housing 110 through the air outlet 117, effectively ensuring the cleanliness inside the housing 110.

[0049] In summary, the indoor unit 100 of the floor-standing air conditioner in this embodiment includes: a housing 110, with a cavity 111 defined inside it, and the housing 110 includes an air inlet grille 115; a heat exchanger 120, disposed in the cavity 111, configured to exchange heat for the air entering the cavity 111; and a baffle 140, disposed between the heat exchanger 120 and the air inlet grille 115, configured to fix the heat exchanger 120 and the air inlet grille 115 and play a buffering role. By providing the baffle 140 between the heat exchanger 120 and the air inlet grille 115, the transportation impact can be effectively reduced, and it can be avoided that the deformation of the air inlet grille 115 caused by transportation drops collides with the heat exchanger 120, ensuring the working reliability of the indoor unit 100 of the floor-standing air conditioner and improving the user experience.

[0050] Furthermore, for the indoor unit 100 of the vertical air conditioner according to this embodiment, the air inlet grille 115 includes a main body portion 151 and support portions 152 on the left and right sides of the main body portion 151. It changes the traditional support of the air inlet grille columns from two sheet metal columns on the left and right to the support portions 152 and the main body portion 151 as a single component, achieving the integration of the air inlet grille 115 while taking into account the support strength. The filter screen is arranged at the air inlet grille 115 and is configured to perform primary filtration on the air entering the cavity 111. Moreover, the baffle 140 is also configured to: serve as a track for the filter screen so that the filter screen can slide in for installation, and the baffle 140 realizes the function of the filter screen track; the baffle 140 is also configured to: serve as an obstacle to the elbow 122 to prevent the elbow 122 from being seen from behind the air inlet grille 115. By arranging the baffle 140, a single component can achieve multiple functions, effectively simplifying the structure of the indoor unit 100 of the vertical air conditioner and effectively improving the overall visual effect of the indoor unit 100 of the vertical air conditioner.
