Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a cabinet air conditioner with energy-saving function. Background Art

[0002] Cabinet air conditioners are a common type of air conditioner, usually in the shape of a vertical cabinet, placed on the ground, mainly used to adjust the indoor temperature, and suitable for use in large spaces. Cabinet air conditioners usually have filters at the air inlet to prevent impurities such as dust and lint from being sucked in and adhering to electrical components such as the evaporator, and to prevent the air conditioner from blowing out odorous gases. However, the filter is easily clogged by impurities after long-term use, which hinders air flow and reduces the amount of air entering the evaporator, resulting in reduced refrigeration efficiency and slower cooling speed. At the same time, it forces the compressor to operate at high load for a long time, increasing energy consumption and accelerating component aging. Long-term blockage can also cause problems such as evaporator freezing and condensate leakage. Cabinet air conditioners are usually placed in corners due to their large size, making it inconvenient to move and disassemble them to clean the filters, and traditional cleaning requires shutdown operations, affecting equipment continuity. Summary of the invention

[0003] In order to overcome the shortcomings of existing cabinet air conditioners that it is inconvenient to move and disassemble them to clean the filters, and traditional cleaning requires shutdown operations, which affects the continuity of the equipment, the present invention provides a cabinet air conditioner with energy-saving function.

[0020] A vertical plate 61 is disposed at the lower side of the scraper 6 , and the scraper 6 and the vertical plate 61 are disposed together in an L shape.

[0021] It also includes a wedge-shaped block 103; two wedge-shaped blocks 103 that are symmetrical to each other are fixedly connected to the upper side of the shielding plate 102.

[0022] The scraper blade 201 is arranged to be inclined from the upper rear side to the lower front side.

[0023] A plurality of spring beads 10301 are disposed on opposite sides of the two wedge-shaped blocks 103 ; a rubber block 20101 is disposed on the scraper blade 201 , and the housing 3 is fixedly connected to the scraper blade 201 via the rubber block 20101 .

[0024] It also includes a protective grille 8; the first air inlet 1001 is provided with a protective grille 8, which prevents film-like debris from covering the surface of the filter screen 4.

[0025] It also includes a second driving member 301 and a push piece 302; the second driving member 301 is fixedly connected to the shell 3, and the second driving member 301 is an electric push rod; the output end of the second driving member 301 passes through the shell 3 and the dust storage box 7, and the output end of the second driving member 301 is fixedly connected to the push piece 302; the front side of the dust storage box 7 is provided with an opening, and a blocking block is provided at the opening.

[0026] The surface of the scraper blade 201 is coated with an anti-stick coating to reduce the adhesion between foreign matter and the scraper blade 201 .

[0027] The cleaning process of the cabinet air conditioner with energy-saving function of the present invention is as follows: When working, impurities such as dust and lint in the air are intercepted by the filter 4.

[0028] As time goes by, more impurities will be intercepted on the filter 4. In order to ensure the ventilation effect of the filter 4 and avoid excessive power consumption, the first driving member 5 is regularly controlled to push the scraper 6 to move downward, so that the scraper 6 scrapes downward from the upper side of the filter 4, and the impurities attached to the filter 4 are gradually scraped off. Then the impurities fall downward to the dust storage box 7 for collection, thereby realizing the cleaning of the filter 4 without stopping the machine. When the dust storage box 7 is full of impurities, the sealing block at the front opening of the dust storage box 7 is manually removed, and then the second driving member 301 is controlled to push the push piece 302 to move forward, so that the impurities in the dust storage box 7 are pushed forward to the front opening of the dust storage box 7 through the push piece 302 for discharge.

[0029] It should be noted that in the process of the scraper 6 scraping the filter 4, the area above the scraper 6 is the cleaned area, and the area of ​​the filter 4 located below the scraper 6 is the uncleaned area. Since the fan 2 is continuously sucking, and under the scraping of the scraper 6, the dust impurities on the filter 4 are continuously scraped off and re-adhere to the uncleaned area, but some lighter dust escapes to the surrounding area, and the cleaned area has a large airflow due to being unblocked, which makes it easy for the floating dust to be sucked into the cleaned area and re-attached to the filter 4, affecting the cleaning effect. In order to avoid this situation, the scraper 6 and the vertical plate 61 are arranged in an L shape. In the process of the scraper 6 scraping the filter 4 downward, the area below the scraper 6 is blocked by the vertical plate 61 to block the floating dust, thereby increasing the difficulty of the floating dust escaping upward, which is conducive to ensuring the cleaning effect of the filter 4.

[0030] Furthermore, in order to prevent the dust stored in the dust box 7 from being sucked back by the fan 2 and attached to the filter 4 when the scraper 6 is reset upward, the upper opening of the dust box 7 is blocked by the shielding plate 102. Figure 7 As shown, when the scraper 6 moves down to the vertical plate 61 and contacts the wedge block 103, the scraper 6 continues to move down to squeeze the upper inclined surface of the wedge block 103. Under the squeezing action of the scraper 6, the wedge block 103 and the baffle plate 102 are pushed to slide backward, and the elastic member 101 is compressed, releasing the baffle plate 102 from blocking the upper opening of the dust storage box 7, so that the impurities scraped from the filter 4 can smoothly fall into the dust storage box 7. When the first driving member 5 drives the scraper 6 to reset upward and the scraper 6 is disengaged from the wedge block 103, the elastic member 101 pushes the baffle plate 102 and the wedge block 103 to reset forward.

[0031] It should be noted that during the process of the scraper 6 scraping the filter 4, some impurities fall downward to the upper side of the baffle plate 102 and the scraper blade 201. This part of the impurities is not collected in the dust storage box 7, resulting in being sucked back onto the filter 4 during subsequent operation. When the scraper 6 squeezes and pushes the wedge block 103 and the baffle plate 102 to move backward, the scraper blade 201 moves forward relative to the baffle plate 102, so that the dust on the surface of the baffle plate 102 is scraped off by the scraper blade 201 and falls into the dust storage box 7 to ensure that this part of the dust is collected in the dust storage box 7. Furthermore, since the scraper blade 201 is in a rear upper side and forward downward direction, the dust on the surface of the baffle plate 102 is scraped off by the scraper blade 201 and falls into the dust storage box 7. The side tilted setting makes it difficult for dust to accumulate on the upper side of the scraper blade 201, and it falls along the inclined surface to the upper side of the baffle plate 102. In the process of the scraper blade 201 scraping the baffle plate 102, since the scraper blade 201 is connected to the shell 3 through the rubber block 20101, the scraper blade 201 will contact and squeeze the spring bead 10301. When the scraper blade 201 passes over the spring bead 10301, the spring bead 10301 pops outward and hits the scraper blade 201, causing the scraper blade 201 to vibrate continuously, thereby effectively promoting the shaking off of impurities on the upper side of the scraper blade 201, and avoiding the impurities from continuing to accumulate on the scraper blade 201.

[0032] According to the above workflow, we can know that the present invention has the following effects: By periodically controlling the first driving member 5 to push the scraper 6 to move downward, the scraper 6 can scrape downward from the upper side of the filter 4 to gradually scrape off the impurities attached to the filter 4, and then the impurities fall downward to the dust storage box 7 for collection, thereby achieving the cleaning of the filter 4 without stopping the machine, ensuring the air permeability of the filter 4, and preventing the filter 4 from being easily blocked by impurities after long-term use, hindering the air flow, reducing the air volume entering the evaporator, resulting in a decrease in refrigeration efficiency and a slow cooling speed, and forcing the compressor to run at high load for a long time, increasing energy consumption and accelerating component aging, which is beneficial to energy saving.

[0033] The upper opening of the dust box 7 is thus blocked by the baffle plate 102 to prevent the dust stored in the dust box 7 from being re-sucked by the fan 2 and attached to the filter 4. When the scraper 6 moves down to the vertical plate 61 and contacts the wedge block 103, the scraper 6 pushes the wedge block 103 and the baffle plate 102 to slide backward, releasing the baffle plate 102 from blocking the upper opening of the dust box 7, so that impurities scraped from the filter 4 fall smoothly into the dust box 7. When the first driving member 5 drives the scraper 6 to reset upward and the scraper 6 is disengaged from the wedge block 103, the elastic member 101 pushes the baffle plate 102 and the wedge block 103 to reset forward.

[0034] When the scraper 6 squeezes and pushes the wedge block 103 and the baffle plate 102 to move backward, the scraper blade 201 moves forward relative to the baffle plate 102, so that the dust falling on the surface of the baffle plate 102 is scraped off by the scraper blade 201 and falls into the dust storage box 7, so as to ensure that this part of the dust is collected in the dust storage box 7 to avoid being sucked back onto the filter 4 during subsequent operation. In the process of the scraper blade 201 scraping the baffle plate 102, the scraper blade 201 will contact and squeeze the spring bead 10301, so that the scraper blade 201 continues to vibrate, thereby effectively promoting the shaking off of impurities on the upper side of the scraper blade 201 to avoid the continuous accumulation of impurities on the scraper blade 201.

[0035] The additional technical effects of the present invention are as follows: Among them, Figure 4 As shown, a protective grille 8 is provided at the first air inlet 1001 for protection, thereby preventing foreign objects from entering the housing 3 through the first air inlet 1001 and causing damage to parts in the housing 3.

[0036] Example 2 On the basis of Example 1, Figure 2-Figure 5 As shown, a second air inlet 1002 is arranged on the right side of the cabinet 1, and the first air inlet 1001 is connected to the second air inlet 1002; the protective grille 8 is inclined from the left rear side to the right front side, and the first air inlet 1001 and the second air inlet 1002 are both located on the outside of the protective grille 8.

[0037] It also includes a ventilation duct 401 ; the upper side of the shell 3 is connected to the ventilation duct 401 ; the ventilation duct 401 runs through the cabinet 1 .

[0038] The workflow of the above embodiment is as follows: Since the present invention is usually placed against a wall for use, when the first air inlet 1001 is close to other objects such as walls or curtains, this will cause the air flow path to be narrow, and even cause the first air inlet 1001 to be blocked, thereby seriously affecting the amount of air entering the first air inlet 1001, which is not conducive to energy saving. The protective grille 8 is inclined from the left rear side to the right front side. When the first air inlet 1001 is blocked, air is inhaled from the second air inlet 1002, and at the same time, air is inhaled through the ventilation duct 401, thereby effectively ensuring the amount of air blown out, allowing the present invention to operate normally, avoiding long-term high-load operation of the compressor, and is conducive to energy saving.

[0039] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
