Description

Technical Field

[0001] This invention relates to the field of air conditioning, specifically to a wall-mounted air conditioner with an upper air outlet and an air outlet mode switching function. Background Technology

[0002] With the continuous improvement of living standards, consumers have higher requirements for the health, comfort, and appearance of air conditioners. Currently, conventional wall-mounted air conditioners on the market (see...) Figure 14 The blades can only achieve a left-right or up-down swing effect, making it difficult to prevent strong airflows from blowing directly on people (see...). Figure 13 The discomfort caused by this, especially during sleep, can easily lead to colds and fevers.

[0003] In hot summer weather, when air conditioners are running in cooling mode, the denser cold air tends to sink in indoor environments. Therefore, even with airflow guides or sweeping devices at the indoor unit's air outlet, the cold air blown out can still cause discomfort for users. This is especially true when the indoor temperature is high and rapid cooling is urgently needed, and the indoor space is small, leaving users with no way to avoid direct blasts of cold air from the air conditioner, significantly reducing the user experience.

[0004] The pain point is that elderly people, women, and children with weaker constitutions are very prone to physical discomfort in the summer. In addition, the cold air from conventional air conditioners on the market can blow onto the head, neck, and joints, causing discomfort. This has led to many elderly people saying, "I don't need air conditioning. I don't need to turn on the air conditioner. I only need an electric fan." This is a common occurrence around us.

[0005] In winter, when the weather is cold and the air conditioner is in heating mode, the temperature at the air outlet is much higher than the indoor air temperature. Therefore, the density of the air outlet is less than the density of the indoor air. This causes the less dense hot air to rise, meaning that the hot air cannot reach the ground. The lower levels of the room where people are active do not receive enough heat, and the temperature rises less. Meanwhile, the temperature in the upper levels of the room rises higher and higher. This is the main reason why people generally say that the air conditioner has poor heating effect and poor comfort.

[0006] The problem is that the hot air cannot be blown directly to the ground to form a heat circulation. Instead, the hot air blows directly onto the head and face, making people feel drowsy. This is the opposite of the optimal state for the human body, where the feet are warm and the head is cool. The poor experience means that although every household has installed air conditioning, the usage rate of air conditioning in winter is very low. This is far from the original intention of buying air conditioning to have a warm winter, leaving many users to rely on their own bodies to get through the winter.

[0007] As people's demands for air conditioning comfort increase, the market demand for zero-wind-feel air conditioners is growing stronger. Other solutions adopted by competitors in the market include:

[0008] 1. Temporary External Windshield Method: Some windshield products for air conditioners have appeared on the market. These products are usually fixedly installed at the air outlet of the air conditioner to prevent the air coming out of the outlet from blowing directly on the user. When in use, the temporary external windshield needs to be manually fixed to the air outlet of the air conditioner. When not in use, the windshield needs to be manually folded to the side of the air conditioner.

[0009] 2: Adjustable wind shield with holes: This method of preventing direct airflow by opening holes in the wind shield can achieve the effect of preventing direct airflow. However, when it is not necessary to prevent direct airflow, but requires air guidance or long-distance air delivery, the through holes on the air guide plate can be adjusted to open or close.

[0010] 3. Windproof curtain method: The air conditioner is equipped with a windproof device at the air outlet. The windproof curtain blocks the air coming out of the air outlet and prevents the wind from blowing towards the user.

[0011] In conclusion, to avoid the discomfort caused by conventional wall-mounted air conditioners blowing cooling and heating air directly at people, we need to improve the product experience rather than adding ineffective and cumbersome external components. We need to address this pain point by starting with the principles of airflow and solving the root cause of the problem. Summary of the Invention

[0012] The purpose of this invention is to provide a wall-mounted air conditioner with an upper air outlet and an air outlet mode switching function, so as to solve the problems mentioned in the background art.

[0013] To achieve the above objectives, the present invention provides the following technical solution: a wall-mounted air conditioner with an upper air outlet and an air outlet mode switching, comprising an indoor unit casing with a panel, an evaporator installed inside the indoor unit casing, a filter and sterilization module, and an air inlet and an upper air outlet opened on the indoor unit casing, wherein the air inlet is located on the top or back side of the indoor unit casing, the upper air outlet is located on the upper front side of the indoor unit casing, an air outlet component is installed on the upper air outlet, a cross-flow air duct is formed between the upper air outlet and the air inlet, and a cross-flow fan is installed inside the cross-flow air duct; the air outlet component includes an air outlet louver unit, an electric push rod, and an air outlet sealing plate, wherein the air outlet louver unit has an air outlet frame, multiple vertical louvers movably connected to the inner side of the air outlet frame by pins, a connecting column fixed to the upper side of the vertical louvers, and a moving strip fitted on the connecting column at the front end of the multiple vertical louvers.

[0014] Preferably, a rack A is provided on the rear side of the moving strip, and a gear drive structure A that meshes with the rack A is provided on the inner side of the indoor unit housing.

[0015] Preferably, the electric push rod is fixed inside the rear side of the indoor unit housing, and the shaft end of the electric push rod is connected to the air outlet sealing plate. The position of the air outlet sealing plate corresponds to the position of the upper air outlet. The air outlet sealing plate can move with the electric push rod and approach or move away from the upper air outlet.

[0016] Preferably, the air outlet louver unit also has horizontal louvers, a gear drive structure B, and a rack B, wherein the gear drive structure B is installed inside the left side of the indoor unit casing; the side of the air outlet frame near the gear drive structure B is provided with a vertical adjustment groove, and a hinge bracket is provided in front of the adjustment groove. The hinge bracket includes a horizontal bracket and two side brackets hinged to the ends of the horizontal bracket. A rack B is provided in the middle of the horizontal bracket, and the rack B can mesh with the gear drive structure B. A sliding column is connected to the hinge of the horizontal bracket and the side bracket, and the sliding column extends into the adjustment groove of the air outlet frame.

[0017] Preferably, there are two sets of horizontal louvers, which are mounted on the inside of the upper air outlet by pins. The end of the side bracket of the hinge bracket is connected to the middle of the horizontal louvers. In the cooling mode, the hinge bracket can drive the horizontal louvers to deflect through the side bracket when the gear drive structure B is started, so that the horizontal louvers swing and the cold air is output to the upper side in parallel from the upper air outlet. The cold air is close to the upper ceiling of the house.

[0018] Preferably, the right side of the indoor unit casing is also equipped with a gear drive structure C that drives the air outlet louver unit to move. A rack C is connected to the side of the air outlet frame away from the gear drive structure B, and the rack C cooperates with the gear drive structure C. In the air conditioning heating mode, the gear drive structure C can mesh with the rack C and move the air outlet frame outward to the upper air outlet. At the same time, the gear drive structure B starts and drives the horizontal louvers to deflect through the side bracket. At this time, hot air is vertically output from the upper air outlet to the lower side, and the hot air is close to the ground.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention places the air conditioner's air outlet at the top of the air conditioner. During cooling operation, this effectively prevents the air from blowing directly onto people, thus avoiding discomfort in the head, neck, and joints. The top-mounted air outlet allows the airflow to be closer to the upper part of the ceiling, creating a Coanda effect that directs air upwards, allowing cool air to flow along the ceiling. Utilizing the principle that denser cold air naturally sinks, this design prevents direct airflow, creating air convection and resulting in a more even and comfortable decrease in indoor temperature.

[0021] 2. During heating operation, the density of the hot air outlet is less than that of the indoor air, causing the less dense hot air to rise and fail to reach the ground. This results in insufficient heat reaching the lower levels of the room where people are active. Therefore, by switching modes, the air outlet sealing plate is moved backward and the air outlet is opened. At this time, by adjusting the gear drive structure C to mesh with the rack C, the air outlet frame is moved outward to the upper air outlet. Then, the air outlet louver unit is deflected, enabling the downward hot air to flow vertically downward and creating a Coanda effect. The hot air directly reaches the ground and forms air convection, resulting in a more even and sustained temperature in the room.

[0022] 3. The air outlet component of this invention can be controlled and linked with the air conditioning control system, and automatically adjusts as the heating / cooling mode is switched, which can improve the product experience, and the overall body is beautiful and elegant.

[0041] Please see Figure 1-12This invention provides a technical solution: a wall-mounted air conditioner with an upper air outlet and an air outlet mode switching, comprising an indoor unit housing 1 with a panel, an evaporator installed inside the indoor unit housing 1, a filter and sterilization module, and an air inlet 2 and an upper air outlet 3 opened on the indoor unit housing 1, wherein the air inlet 2 is located on the top or back side of the indoor unit housing 1, the upper air outlet 3 is located on the upper front side of the indoor unit housing 1, an air outlet component is installed on the upper air outlet 3, a cross-flow air duct is formed between the upper air outlet 3 and the air inlet 2, and a cross-flow fan wheel 5 is installed in the cross-flow air duct; the air outlet component includes an air outlet louver unit, an electric push rod 11, and an air outlet sealing plate 12, wherein the air outlet louver unit has an air outlet frame 6, multiple vertical louvers 7 movably connected to the inner side of the air outlet frame 6 by a pin, a connecting column 4 fixed to the upper side of the vertical louvers 7, and a moving strip 8 fitted on the connecting column 4 at the front end of the multiple vertical louvers 7.

[0042] In this embodiment, a rack A9 is provided on the rear side of the moving strip 8, and a gear drive structure A10 that meshes with the rack A9 is provided on the inner side of the indoor unit housing 1. The rack A9 is moved by the gear drive structure A10, which can cause the rack A9 to drive the vertical louvers 7 on it to deflect through the connecting column 4, thereby realizing the adjustment of the left and right angles of the vertical louvers 7, and thus realizing the adjustment of the blowing direction.

[0043] In this embodiment, the electric push rod 11 is fixed inside the rear side of the indoor unit housing 1. The shaft end of the electric push rod 11 is connected to the air outlet sealing plate 12. The position of the air outlet sealing plate 12 corresponds to the position of the upper air outlet 3. The air outlet sealing plate 12 can move with the electric push rod 11 and approach and move away from the upper air outlet 3.

[0044] In this embodiment, the air outlet louver unit also has a horizontal louver 16, a gear drive structure B13, and a rack B14. The gear drive structure B13 is installed inside the left side of the indoor unit housing 1. The air outlet frame 6 has a vertical adjustment groove 17 on the side near the gear drive structure B13. A hinge bracket 15 is provided on the front side of the adjustment groove 17. The hinge bracket 15 includes a horizontal bracket and two side brackets hinged to the ends of the horizontal bracket. A rack B14 is provided in the middle of the horizontal bracket. The rack B14 can mesh with the gear drive structure B13. A sliding column 18 is connected at the hinge of the horizontal bracket and the side bracket. The sliding column 18 extends into the adjustment groove 17 of the air outlet frame 6.

[0045] In this embodiment, there are two sets of horizontal louvers 16, which are mounted on the inner side of the upper air outlet 3 by means of pins. The end of the side bracket of the hinge bracket 15 is connected to the middle of the horizontal louvers 16. In the cooling mode, the hinge bracket 15 can drive the horizontal louvers 16 to deflect through the side bracket when the gear drive structure B13 is started, so that the horizontal louvers 16 swing and the cold air is output to the upper side in parallel from the upper air outlet 3. The cold air is close to the upper ceiling of the house.

[0046] like Figure 4 As shown, in this embodiment, the right side of the indoor unit casing 1 is also equipped with a gear drive structure C19 that drives the air outlet louver unit to move downward. The side of the air outlet frame 6 away from the gear drive structure B13 is connected to a rack C20, and the rack C20 cooperates with the gear drive structure C19. In the air conditioning heating mode, the gear drive structure C19 can mesh with the rack C20 and move the air outlet frame 6 (air outlet louver unit) outward from the upper air outlet (3); at the same time, the gear drive structure B13 starts to drive the horizontal louver 16 to deflect through the side bracket. At this time, the hot air is vertically output from the upper air outlet 3 to the lower side, and the hot air is close to the ground.

[0047] Cooling mode:

[0048] Step 1: Connect the air conditioner to the power supply;

[0049] Step 2: Turn on the air conditioner using a remote control (or mobile phone remote control), wherein the air outlet sealing plate 12 is opened by moving the electric push rod 11;

[0050] Step 3: Select the air conditioning cooling mode. In cooling mode, when the gear drive structure B13 starts, it drives the horizontal louvers 16 to deflect via the side bracket, causing the horizontal louvers 16 to swing. At this time, cold air is output horizontally upwards from the upper air outlet 3 (e.g., Figure 7 , 10 As shown), the cold air is close to the upper part of the ceiling of the house;

[0051] Step 4: Adjust the vertical louvers to angle 7.

[0052] Step 5: Adjust the set cooling temperature.

[0053] Heating mode:

[0054] Step 1: Connect the air conditioner to the power supply;

[0055] Step 2: Turn on the air conditioner using a remote control (or mobile phone remote control), wherein the air outlet sealing plate 12 is opened by moving the electric push rod 11;

[0056] Step 3: Select the air conditioning heating mode. The gear drive structure C19 meshes with the rack C20 on the side of the air outlet frame 6, causing the entire air outlet frame 6 to move outwards beyond the upper air outlet 3. Simultaneously, the gear drive structure B13 starts, driving the horizontal louvers 16 to deflect via the side bracket. At this time, hot air is vertically output from the upper air outlet 3 to the lower side (e.g., Figure 9 , 11 (As shown), the hot air is close to the ground;

[0057] Step 4: Adjust the vertical louvers to angle 7.

[0058] Step 5: Adjust the set heating temperature.

[0059] This invention effectively prevents the air from blowing directly onto people during cooling operation, thus avoiding discomfort in the head, neck, and joints. The top-mounted air outlet (top air outlet 3) allows the air to be closer to the upper part of the ceiling, creating a Coanda effect that directs airflow upwards, allowing cool air to flow along the ceiling. Utilizing the principle that denser cold air naturally sinks, this design prevents direct airflow and creates air convection, resulting in a more even and comfortable decrease in indoor temperature.

[0060] When the present invention is in heating mode, the density of the hot air outlet is less than that of the indoor air, causing the less dense hot air to rise and fail to reach the ground, resulting in insufficient heat for the lower levels of the room where people are active. Therefore, by switching modes, the air outlet sealing plate 12 is moved downward and the upper air outlet 3 is opened. At this time, the gear drive structure C19 drives the air outlet frame 6 to move outward and adjusts the deflection of the air outlet louver unit, so that the downward hot air can be directed vertically downward and the airflow can form a Coanda effect, allowing the hot air to directly reach the ground and form air convection, making the room temperature more even and the heat more lasting.

[0061] The entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0062] It is worth noting that the air outlet mode switching involved in this invention refers to the different air outlet methods adopted by the air conditioner in cooling / heating mode (cold air is output horizontally upwards, and hot air is output vertically downwards).

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
