Description

Technical Field

[0001] The present invention relates to air conditioning technology, and in particular to an air conditioning outdoor unit and an air conditioning unit. Background Art

[0002] In today's air conditioning industry, for the outdoor heat exchanger of the top-outlet air conditioner, the wind field distribution of the heat exchanger is uneven, and the air volume of the lower heat exchanger is lower than that of the upper heat exchanger. In the heating mode, the frost speed of the lower heat exchanger is faster than that of the upper heat exchanger, resulting in a short steady-state heating time of the whole machine and frequent defrosting. At the same time, due to the large amount of frost on the lower heat exchanger, it may even freeze. When the air conditioner enters the defrost mode, in order to completely remove the frost on the lower heat exchanger, the defrost time will be extended.

[0003] In order to speed up defrosting, the conventional method is to control the fan to reverse when defrosting is basically completed, and use wind to blow away the frost and ice water on the heat exchanger to speed up defrosting. However, conventional wind defrosting cannot perform strong defrosting on the lower heat exchanger, and the defrosting effect is poor. This leads to the increase in air conditioning energy consumption and seriously affects the comfort of users. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0022] In order to solve the technical problem of poor defrosting effect of the air conditioner outdoor unit in the prior art, Figure 1 and Figure 2As shown, the present invention provides an embodiment of a wind grid assembly, which includes a grid body 10 and a wind grid plate 20 installed on the grid body 10, and a heating element 30 is arranged on the wind grid plate 20 located at the lower part of the grid body 10, and the heating element 30 is used to heat the lower part of the heat exchanger during defrosting.

[0023] In order to solve the problem in the prior art that the lower part of the heat exchanger is more prone to frost and more difficult to defrost, the technical solution of the present invention provides a heating element 30 on the wind grid plate 20 at the lower part of the grid body 10. During defrosting, the lower part of the heat exchanger can be heated by the heating element 30, which helps to improve the defrosting efficiency of the lower part of the heat exchanger, ensure the efficient operation of the air conditioner, and improve the comfort of users.

[0024] like Figure 1 As shown, optionally, in the technical solution of this embodiment, the wind grid plate 20 includes a first wind grid plate group 20a and a second wind grid plate group 20b, the first wind grid plate group 20a is installed on the upper part of the grid body 10, the second wind grid plate group 20b is installed on the lower part of the grid body 10, and the heating element 30 is installed on the second wind grid plate group 20b. In this way, the lower part of the heat exchanger can be heated. As an optional embodiment, in the technical solution of this embodiment, the distribution heights of the first wind grid plate group 20a and the second wind grid plate group 20b on the grid body 10 are equal. As other optional embodiments, the distribution heights of the first wind grid plate group 20a and the second wind grid plate group 20b on the grid body 10 may also be unequal.

[0025] More preferably, in order to ensure that the heating element 30 can evenly and fully heat the lower part of the heat exchanger, the heating element 30 is respectively installed on each plate of the second grid plate group 20b. As another optional embodiment, the heating element 30 can also be selectively installed on some plates in the second grid plate group 20b.

[0026] In the technical solution of this embodiment, the wind grid plate 20 located at the upper part of the grid body 10 can be opened and closed. In this way, the outdoor cold air can be prevented from communicating with the space where the heat exchanger is located during defrosting, thereby improving the heat preservation effect; when the defrosting is about to end, the wind grid plate 20 located at the upper part of the grid body 10 is closed, and the fan of the outdoor unit is started to reverse, which can increase the strength of the reverse airflow at the lower part of the heat exchanger and improve the purging effect of frost and ice water at the lower part of the heat exchanger.

[0027] More preferably, in the technical solution of this embodiment, the wind grid plate 20 located at the lower part of the grid body 10 can be opened and closed. Similarly, during defrosting, the outdoor cold air can be prevented from communicating with the space where the heat exchanger is located, thereby improving the heat preservation effect; at the stage when defrosting is about to end, only the wind grid plate 20 located at the lower part of the grid body 10 is opened, and then the fan of the outdoor unit is started to reverse, which can increase the strength of the reverse airflow at the lower part of the heat exchanger and improve the purging effect of frost and ice water at the lower part of the heat exchanger.

[0028] Optionally, in the technical solution of this embodiment, the wind grid assembly further includes a first driving member, which is drivingly connected to the wind grid plate 20 at the upper part of the grid body 10. The wind grid assembly further includes a second driving member, which is drivingly connected to the wind grid plate 20 at the lower part of the grid body 10. Figure 1 As shown, in the technical solution of this embodiment, the driving structure of the first driving member and the second driving member can be: a gear is installed on the rotating shaft of the wind grid plate 20, and then meshed with the gear through the gear belt 40, a driving part is formed on any one of the gears, and the motor is connected to the driving part to drive the gear to rotate, which can drive the other wind grid plates 20 to rotate.

[0029] It should be noted that the lower part of the heat exchanger mentioned above refers to the part of the heat exchanger in the outdoor unit of the air conditioner where the air flow is blocked by other air conditioning components. The lower part of the heat exchanger can be below the middle part of the heat exchanger or near the bottom of the heat exchanger.

[0030] Preferably, in the technical solution of this embodiment, the heating element 30 is an electric heating belt. When in use, the electric heating belt is powered on to generate heat to heat the lower part of the heat exchanger. As another optional embodiment, the heating element 30 may also be a heat radiation belt. The use of a heat radiation belt allows the heat radiation belt to radiate more heat to the lower part of the heat exchanger, thereby improving the defrosting efficiency of the lower part of the heat exchanger.

[0031] The present invention also provides an air conditioner outdoor unit, which includes a heat exchanger and a wind grille assembly installed at the heat exchanger, wherein the wind grille assembly is the above-mentioned wind grille assembly. The air conditioner outdoor unit using the above-mentioned wind grille assembly can heat the lower part of the heat exchanger through the heating element 30 during defrosting, thereby helping to improve the defrosting efficiency of the lower part of the heat exchanger, ensuring the efficient operation of the air conditioner, and improving the comfort of the user.

[0032] More preferably, in the technical solution of this embodiment, the air grille assembly is installed on the inner side of the heat exchanger. In this way, when defrosting is about to end, the fan of the outdoor unit is started to reverse, so that the hot air flow generated by the heating element 30 of the air grille assembly can effectively blow away the frost and ice water at the bottom of the heat exchanger.

[0033] More preferably, the present invention further provides an air conditioning unit, which includes the above-mentioned air conditioning outdoor unit. The air conditioning unit using the above-mentioned air conditioning outdoor unit can improve the defrosting efficiency of the air conditioning unit, thereby improving the comfort of the user.
