Other manufacturers use air to achieve heat storage, but the heat storage capacity is relatively low. weak.

The toothed perforated plate is mostly used in the existing heat storage radiation panels. The principle is that the high-pressure airflow generated by the duct fan enters the radiation panel through the air inlet and enters the toothed area. Because the toothed area has many small holes, a certain damping is formed. , causing the wind to form a vortex in the toothed area, heating the aluminum panel, and forming a certain heat storage, while reducing the wind speed to form a breeze.

However, the air outlet volume in the middle of the heat storage panel is too large, and a backflow is formed in the nearby area, and the air velocity distribution of the panel is uneven, which reduces the user's comfort.

For the methods, products, etc. disclosed in the embodiments, since they correspond to the method parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

Referring to FIGS. 1 to 4 , it is the basis for the improvement of the air outlet device of the air conditioner according to the embodiment of the present invention. In the air outlet device of the air conditioner shown in FIGS. 1 to 4 , the induced air duct 5 is L-shaped. There are the following problems:

First, when the air outlet device of the air conditioner is running, the induced wind will turn 90 degrees at the corner of the induced air duct 5, and the induced wind will collide at the rounded corners on the left and right sides of the curved plate, resulting in the loss of the induced air volume. , resulting in a decrease in air outlet efficiency.

Second, the induced air inlet is on the same side as the air outlet 7 of the air outlet device of the air conditioner, which will cause the air out of the system to be affected by the induced air and be sucked into the induced air duct 5 again, which will affect the air outflow of the system to spread indoors, making the air outlet. The air outlet in 7 cannot fully adjust the indoor air temperature, which reduces the temperature adjustment efficiency.

Third, the overall width of the attracting air duct 5 is too large, which increases the installation area of the attracting device 2 . The overall width of the inducer = the width of the inducer air inlet × 2 + the width of the air outlet = 90 ×

2+300=480mm, where 90 is the width of the induced air inlets on both sides, and 300 is the width of the air outlet.

The present invention is an improvement based on the above-mentioned problems.

Referring to FIGS. 5 to 8 , according to an embodiment of the present invention, the air outlet device of the air conditioner includes an air storage device 1 and an inducement device 2 , and the air storage device 1 includes an air storage chamber 3 and a gas booster connected to the air storage chamber 3 . The speed structure 4, the inducement device 2 includes an inducement air duct 5, a mixing port 6, an air outlet 7 and a heat storage device 8, and the heat storage device 8 is arranged between the outlet of the mixing port 6 and the air outlet 7, and the heat storage device 8 A space for equalizing flow is formed between the side wall of the inducement air duct 5, and the inducement air duct 5 is in a straight line shape, including two oppositely arranged inducement air inlets, and the induced air flows from the inducement air inlet through the inducement air duct 5. The mixing port 6 is mixed with the gas flow accelerated by the gas increasing structure 4 .

The above-mentioned air-conditioning air outlet device can accelerate the formation of negative pressure through the air of the gas speed-increasing structure 4 when the air-conditioning air outlet, so as to form a suction force for the air at the inlet of the induced air duct 5, so that the air outside the air duct 5 is induced. It can enter the mixing port 6 along the induced air duct 5, form a mixture with the accelerated air, induce the mixed air to enter the heat storage device 8, and pass through the heat storage device 8 to equalize the air to intercept a part of the air and intercept it. The rear air flows back on both sides, and passes through the heat storage devices 8 on both sides by pressure, so that the pressure distribution of the air blown out after the heat storage device 8 is more uniform, and the wind speed is more uniform, which improves the user experience.

In addition, the inducement air duct 5 is set in a straight line, and the two inducement air inlets are arranged opposite to each other, and the openings face oppositely and are located on a straight line, which eliminates the 90-degree angle of the inducement air duct 5 from the induced air inlet to the induced air outlet. Turning, so it can overcome the loss of the induced air volume caused by the collision with the rounded corners of the induced wind during a 90-degree turn, so that the induced wind passes through the induced air duct 5 and reaches the mixing port 6 during the process. , the induced wind flow is more balanced and stable, and the mixing with the accelerating wind is also more uniform and stable.

Preferably, the air inlet direction of the induced air inlet is perpendicular to the air outlet direction of the air outlet 7 . Since the windward surface of the heat storage device 8 is perpendicular to the air outlet direction of the air outlet 7, the air inlet direction of the induced air inlet is parallel to the windward surface of the heat storage device 8. As seen from FIG. 5, the induced air inlet is located in the On the windward side of the heat storage device 8, the air outlet 7 is located on the leeward side of the heat storage device 8, so the induced air inlet and the air outlet 7 are located on different sides of the heat storage device 8 respectively, so that the induced air inlet can avoid the air outlet 7, and the system outlet. The wind is not affected by the induced wind, which increases the indoor circulation radius of the air from the induced system and increases the cooling and heating range of the system.

Preferably, the air inlet end surface of the induced air inlet is parallel to the side surface of the heat storage device 8 , and the side surface of the heat storage device 8 is the side wall surface between the windward surface and the leeward surface of the heat storage device 8 .

In this embodiment, the air inlet end face of the induced air inlet is coplanar with the side surface of the heat storage device 8 . Since the air inlet end face of the induction air inlet is coplanar with the side surface of the heat storage device 8, the overall width of the induction device 2 can be reduced, and the installation area can be reduced. Compared with the solution before the improvement, the overall width of the inducement device 2 in this embodiment is the same as the width of the heat storage device 8, which is the width of the heat storage device=the width of the air outlet=300mm, which reduces the production cost and ensures the The equipment is more refined, more miniaturized, and occupies a smaller area.

Preferably, the heat storage device 8 includes heat exchanger fins 9 and heat exchange tubes 10 , the heat exchange tubes 10 contain heat storage materials, and the heat exchanger fins 9 are provided with heat exchanger fins 9 along the thickness direction of the heat exchanger fins 9 . The penetrating communication port 11 .

Since the heat storage device 8 itself includes the heat exchanger fins 9, the air outlet is more uniform, and the uneven air can be evenly distributed. The heat exchanger fins 9 are equivalent to porous media and have certain damping. Part of the air flow passes through the porous media to weaken the strong wind, and the wind speed can be comfortably accepted by the human body. Backflow is generated on the side, and through the heat storage device 8 on both sides through the action of pressure, a stable and uniform air outlet is formed, and the uniformity of the air outlet is improved. Since the heat exchanger fins 9 are provided with the communication ports 11 penetrating the thickness direction of the heat exchanger fins 9 , the spaces between the heat exchanger fins 9 can be communicated, and the air flows through the heat storage device 8 when the air flows through the heat storage device 8 . During the process, a series connection can be formed through the communication port 11, so that the high-pressure air can be balanced to the low pressure, so that the air can be pressure-equalized again in the heat storage device 8, so that the air pressure distribution blown out after the heat storage device 8 is more uniform, The wind speed is more uniform, which improves the user experience.

Specifically, the air storage device 1 of the air outlet device of the air conditioner is connected to the air supply port of the indoor unit, and the cold air or hot air blown from the indoor unit first enters the air storage device 1, and then passes through the air storage device 1 and the inducement device 2. The gas speed-increasing structure 4 between them enters the inducer 2. Since the cross-sectional area of the gas-speed-increasing structure 4 is smaller than that of the air supply port, when the cold air or hot air passes through the gas-increasing structure 4, it will enter the inducement device 2. A negative pressure is formed, so that the indoor air enters the inducement air duct 5 of the inducement device 2 from the inducement inlet of the inducement device 2, and the air entering the inducement air channel 5 exchanges heat with cold air or hot air, and then The heat is exchanged by the heat storage device 8, and then discharged back into the room together through the air outlet 7 of the inducement device 2. With this arrangement, the cold air or hot air blown from the indoor unit can be prevented from being directly discharged into the room, but heat exchange with the indoor air is performed in the inducer 2 first, and then discharged into the room together, so that the cooling can be achieved without The comfortable effect of cold and warm but not hot, improves the user's experience. Among them, the gas storage device 1 is an air storage box. Of course, the gas storage device 1 can also be configured as a gas storage cylinder, a gas storage box, etc. The adjustment and change of the specific structure of the gas storage device 1 does not deviate from the present invention. Both the principle and the scope should be limited within the protection scope of the present invention.

In addition, it should be noted that the cross-sectional area of the gas speed-increasing structure 4 refers to the area of the cross-section through which cold air or hot air passes through the gas-speed-increasing structure 4, and the area of the air supply port refers to the area of the cross-section through which the cold air or hot air passes through the air supply port. . Since the volume of cold air or hot air passing through the gas speed-increasing structure 4 at the same time is the same as the volume of the cold air or hot air passing through the air supply port, and the cross-sectional area of the gas speed-increasing structure 4 is smaller than that of the air supply port, the cold air Or the speed of the hot air passing through the gas increasing structure 4 is greater than the speed passing through the air supply port, so as to realize the increasing speed of the gas and thus form a negative pressure in the inducer 2 to induce indoor air into the inducer 2 .

In this embodiment, the gas speed-increasing structure 4 is a speed-increasing port that communicates the inducement device 2 and the gas storage device 1 . The speed-increasing port can be directly arranged on the side wall of the inducement device 2 or directly in the storage device 1 . on the side wall of the gas device 1. Preferably, an air guide pipe is also provided at the speed-increasing port, and the air-guiding pipe extends toward the mixing port 6, so that the air supply distance of the speed-increasing port can be increased, and a better inducement effect can be achieved. The inner diameter of the air duct should be the same as the diameter of the speed-increasing port.

Preferably, the heat exchanger fins 9 are corrugated sheets, slit sheets or louvers.

Preferably, the heat exchange tube 10 has a double-layer structure, so that a larger heat exchange area can be formed, and more heat storage materials can be stored in the heat storage device 8 to improve the temperature adjustment capability of the heat storage device 8 . The heat exchange tube 10 is, for example, a copper tube.

In one of the embodiments, the heat exchange tubes 10 are U-shaped tubes connected in series, and plugs are provided at the nozzles at both ends of the heat exchange tubes 10 . Two adjacent U-shaped tubes are encapsulated in series through U-shaped elbows, so as to ensure the tightness of the heat storage material. Since the heat storage material is installed in the heat exchange tube 10, and the heat storage material does not need to circulate in other devices, it only needs to be kept in the heat storage device 8, so it is only necessary to plug the two ports of the heat exchange tube with plugs. Hold to form a seal.

In another embodiment, the heat exchange tubes 10 are in a parallel structure, each heat exchange tube 10 is a straight tube, and the port of each heat exchange tube 10 is provided with a plug or at least one of at least each heat exchange tube 10 The ferry is provided with a plug. In this embodiment, the heat exchange tubes 10 are not communicated with each other, and each heat exchange tube 10 is filled with heat storage material.

In another embodiment, the heat exchange tube 10 is a single U-shaped tube, and two ports of each U-shaped tube are respectively provided with plugs or at least one port is provided with a plug. The end of the U-shaped pipe can be sealed at one end and closed at the other end by a plug. The two ports of the U-shaped pipe can also be sealed by the U-shaped elbow.

Preferably, the plurality of communication ports 11 are elongated and extend in the width direction of the heat exchanger fins 9 . By arranging a plurality of elongated communication ports 11, the air communication inside the heat storage device can be more conveniently realized, the uniformity of the gas pressure distribution and the uniformity of the air outlet speed can be ensured.

The heat storage material is paraffin or 65mol% capric acid+35mol% dodecanoic acid and the like. The heat storage material has a large specific heat capacity and a strong heat storage capacity. The phase change heat storage material in the constant temperature defrosting multi-line can be used, or the paraffin wax that is easier to handle can be used.

The material properties of paraffin or 65mol% capric acid + 35mol% dodecanoic acid are shown in the table below:

Referring to Figure 2 and Figure 3, the air first enters the air storage box under the action of the air duct machine, and after filling the air storage box, the gas enters the speed-increasing area, and the gas suddenly accumulates at the outlet section of the speed-increasing port and becomes smaller. , so the accumulation of wind speed increases, and it increases from no more than 6m/s in the air storage box to 7.5m/s at the speed-increasing port, and then enters the mixing port to form a negative pressure. Under the action of the negative pressure, the indoor air is induced The inlet air enters and reaches the mixing port 6 along the induced air duct 5, where it is mixed with the air out of the speed-increasing port, and then the mixed air reaches the heat storage device 8. Under the shielding effect of the heat storage device, part of the The air is blown out after decelerating and depressurizing through the middle part of the heat storage device 8, and another part of the air enters the air equalizing cavity formed between the induced air duct 5 and the heat storage device 8 from both sides, and the gas pressure in the air equalizing cavity is It is decelerated and depressurized through the parts on both sides of the heat storage device 8, and then blown out through the heat storage device 8. Since the flat plane of the heat exchanger fins 9 itself has a rectifying effect, the air flow rate distribution blown out through the heat storage device 8 is more It is uniform and does not produce eddy current and backflow, which effectively improves the air outlet efficiency.

It can be seen from Figure 6 that the overall wind speed of the air blown out after the heat storage device 8 is decompressed and rectified is reduced to below 1.2m/s, and the wind speed of the middle part with the highest wind speed is also reduced to 1m/s On the left and right, except for the middle part corresponding to the mixing port 6 , the wind speed does not exceed 0.5m/s, so the breeze blowing is basically realized, and the user experience is better.
