Description

Technical Field

[0001] This utility model relates to the field of hot water unit technology, specifically a ventilation and dust prevention structure for hot water units. Background Technology

[0002] Air source heat pump water heaters are energy-saving and environmentally friendly hot water supply devices that can replace boilers and are not limited by resources. They use green and pollution-free refrigerant to absorb heat from the air and produce domestic hot water at temperatures above 50°C through the operation of a compressor. Compared with traditional boiler water heaters, they are more environmentally friendly and have a wider range of applications.

[0003] According to the Chinese Utility Model Application No. CN202321736789.8, an air source heat pump water heater unit was proposed. The utility model describes that "the inclined baffle can block the dust carried in the airflow, the water sprayed from the inclined baffle can clean the dust on the inclined baffle, and the water sprayed from the inclined baffle can adhere to the dust in the airflow, so as to prevent the dust from entering the unit and affecting the heat dissipation of the internal electronic components".

[0004] In this air source heat pump water heater unit, the gap between adjacent inclined baffles is relatively large. When ventilation is performed, dust can still easily enter the interior of the water heater unit through the gap, reducing the heat dissipation effect of the internal electronic components. Improvement is needed. Therefore, a ventilation and dust prevention structure for water heater units is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ventilation and dustproof structure for hot water units, which has advantages such as good ventilation and dustproof effects. It solves the problem that when the gaps between adjacent inclined blocks are large, dust can still easily enter the interior of the hot water unit through the gaps during ventilation, reducing the heat dissipation effect of the internal electronic components of the hot water unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and dustproof structure for a hot water unit, comprising a hot water unit body, a ventilation frame fixedly installed on the side wall of the hot water unit body, ventilation holes opened inside the ventilation frame, an annular plate inserted inside the ventilation frame, a filter screen fixedly installed inside the annular plate, an insertion hole opened on the right side of the ventilation frame, an insertion plate matching the annular plate inserted inside the insertion hole, and a movable door embedded on the left side of the ventilation frame.

[0007] Furthermore, the outer wall of the annular plate is provided with a slot, which matches the insert plate.

[0008] Furthermore, a handle is fixedly installed on the side of the insert plate away from the annular plate, and the handle is located in the middle of the right side of the annular plate.

[0009] Furthermore, the inner bottom wall and inner top wall of the ventilation frame are both fixedly installed with ball bearings, and the side of the ball bearings away from the ventilation frame is in contact with the annular plate.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] This ventilation and dustproof structure for hot water units, by setting up the hot water unit body, ventilation frame, ring plate, filter screen, insert plate and movable door, not only does the ventilation frame work with the filter screen to double filter dust, improving the dustproof effect, but the filter screen is also easy to replace, improving the ventilation effect. Furthermore, when ventilating, dust is less likely to enter the interior of the hot water unit body, improving the heat dissipation effect of the internal electronic components of the hot water unit.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 A ventilation and dustproof structure for a hot water unit in this embodiment includes a hot water unit body 1, a ventilation frame 2 fixedly installed on the side wall of the hot water unit body 1, ventilation holes opened inside the ventilation frame 2, an annular plate 3 inserted inside the ventilation frame 2, a filter screen 4 fixedly installed inside the annular plate 3, an insertion hole opened on the right side of the ventilation frame 2, an insertion plate 5 matching the annular plate 3 inserted inside the insertion hole, and a movable door 6 embedded on the left side of the ventilation frame 2.

[0022] Specifically, the operator first moves the insert plate 5 to the right, causing it to move out of the ventilation frame 2 and the annular plate 3. Then, the replacement annular plate 3 is inserted into the ventilation frame 2 and moved, causing the annular plate 3 inside the ventilation frame 2 to move under force and push open the movable door 6 to move out of the ventilation frame 2. Finally, the insert plate 5 is inserted into the ventilation frame 2 and the replacement annular plate 3, and the movable door 6 is closed, completing the replacement of the filter screen 4. The ventilation frame 2, together with the filter screen 4, performs double filtration of dust, improving the dust prevention effect. During ventilation, dust is less likely to enter the interior of the hot water unit body 1, improving the heat dissipation effect of the electronic components inside the hot water unit 1.

[0023] In this embodiment, the outer wall of the annular plate 3 is provided with a slot, which matches the insert plate 5.

[0024] Specifically, the insert block is inserted into the slot, enhancing the connection stability between the ventilation frame 2, the annular plate 3, and the insert plate 5.

[0025] In this embodiment, a handle is fixedly installed on the side of the insert plate 5 away from the annular plate 3, and the handle is located in the middle position on the right side of the annular plate 3.

[0026] Specifically, holding the handle makes it easier to move the plug 5.

[0027] In this embodiment, the inner bottom wall and inner top wall of the ventilation frame 2 are both fixedly installed with ball bearings 7, and the side of the ball bearings 7 away from the ventilation frame 2 is in contact with the annular plate 3.

[0028] Specifically, the friction between the annular plate 3 and the ball bearing 7 is small, making it easier to move the annular plate 3.

[0029] The working principle of the above embodiments is as follows:

[0030] The operator first holds the handle and moves the insert plate 5 to the right, causing it to move out of the ventilation frame 2 and the annular plate 3. Then, the replacement annular plate 3 is inserted into the ventilation frame 2 and moved, causing the annular plate 3 inside the ventilation frame 2 to move under force and push open the movable door 6 to move out of the ventilation frame 2. The friction between the annular plate 3 and the ball bearing 7 is small. Finally, the insert plate 5 is inserted into the ventilation frame 2 and the replacement annular plate 3, enhancing the connection stability between the ventilation frame 2, the annular plate 3 and the insert plate 5. The movable door 6 is then closed, completing the replacement of the filter screen 4. The ventilation frame 2, together with the filter screen 4, performs dual filtration of dust, improving the dust prevention effect. During ventilation, dust is less likely to enter the interior of the hot water unit 1, improving the heat dissipation effect of the electronic components inside the hot water unit 1.
