Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a water purifier with a front-mounted forced exhaust heat dissipation system. Background Art

[0002] An embedded water purifier is a kitchen appliance product integrating multiple water outlet modes, with functions such as making hot water, ice water, and soda water. Among them, the refrigeration function is realized by a compressor module. However, when the compressor works, heat is generated, and the heat cannot be effectively discharged in the limited internal space between the machine and the cabinet, thereby reducing its refrigeration effect or causing overheating shutdown.

[0003] The heat dissipation methods of existing products generally adopt the following two types:

[0004] 1. A heat dissipation fan is installed on the back panel of the product. The fan draws high-temperature air from the inside of the product and blows it out towards the back panel of the cabinet. However, due to the diversity and limitations of the cabinet space, such as less clearance space between the cabinet and the product, the heat dissipation effect is still not good, resulting in a decrease in refrigeration efficiency or overheating shutdown.

[0005] 2. Exhaust heat dissipation holes are provided at the top or back of the product shell and other positions. When refrigerating, the high-temperature air in the product passes through the condenser heat dissipation fan supporting the compressor and blows the hot air outside the product. However, due to the uncertainty of the layout position of the fan, the gas flow direction, and the limitations of the cabinet space, the heat dissipation effect is often not good, resulting in a decrease in refrigeration efficiency or overheating shutdown.

Detailed Embodiments

[0024] The following embodiments are used to illustrate the present utility model, but the present utility model is not limited by these embodiments. Any modification to the specific embodiments of the present utility model or equivalent replacement of some technical features without departing from the spirit of the present utility model shall fall within the scope of the technical solutions claimed by the present utility model.

[0025] Embodiment 1

[0026] Referring to Figures 1-3 , this embodiment provides a water purifier with a front-mounted forced exhaust heat dissipation system, including a housing assembly 1, a refrigeration device (not shown in the figure), a cooling fan 3, and a water circuit system (not shown in the figure). A water receiving cavity 11 with a front opening is recessed on the front surface of the housing assembly 1. An air outlet part 12 through which hot air can pass is arranged on the top cavity wall or side cavity wall of the water receiving cavity 11. The air outlet part 12 is connected to the external atmosphere through the water receiving cavity 11, so that hot air can be discharged from the water receiving cavity 11 through the air outlet part 12, further improving the utilization rate of the water receiving cavity 11, and the product exhaust heat dissipation is not affected by the gap space between the cabinet and the product. An air inlet part 13 through which cold air can pass is arranged on the bottom or side wall of the housing assembly 1, and the interior of the housing assembly 1 is connected to the external atmosphere through the air inlet part 13.

[0027] The refrigeration device is arranged inside the housing assembly 1 and is used to refrigerate the water in the water circuit system. During the refrigeration process of the refrigeration device, heat is generated. If this part of the heat cannot be effectively discharged from the product, it will reduce its refrigeration effect or cause overheating shutdown. To avoid overheating of the internal temperature of the product, which may lead to a decrease in refrigeration efficiency or shutdown, a cooling fan 3 is installed on the outer surface of the water receiving cavity 11 inside the housing assembly 1. The suction port of the cooling fan 3 is connected to the inside of the housing assembly 1, and the exhaust port of the cooling fan 3 is connected to the air outlet part 12. In this way, the air outlet part 12 can be connected to the inside of the housing assembly 1 through the cooling fan 3.

[0028] In this embodiment, the air inlet part 13, the inside of the housing assembly 1, the cooling fan 3, the air outlet part 12, and the water receiving cavity 11 together form a front-mounted forced exhaust heat dissipation system. Through the front-mounted forced exhaust heat dissipation system, the high-temperature air during the refrigeration of the product is discharged from the water receiving cavity 11 through the air outlet part 12, replacing the air inside and outside the housing assembly 1, avoiding overheating of the internal temperature of the product, which may lead to a decrease in refrigeration efficiency or shutdown, improving the heat dissipation effect and refrigeration efficiency of the product, and at the same time being compatible with a smaller cabinet installation space, not limited by the cabinet installation space.

[0029] Since the high-temperature air is discharged from the water receiving cavity 11 through the air outlet part 12, to improve the user experience and prevent the heat dissipation process from affecting the user's water receiving experience, through program setting, the cooling fan 3 is controlled to turn off when the user takes water, and 5 seconds after the water taking is completed, the cooling fan 3 is restarted and works according to the intelligent start-stop logic to limitedly reduce the influence of hot air on the ambient temperature. Among them, the intelligent start-stop logic is specifically: using program setting, the cooling fan 3 dissipates heat in a pulse mode of "on for 3 seconds and off for 5 seconds".

[0030] In this embodiment, the specific operation logic of the front-mounted forced exhaust heat dissipation system is as follows:

[0031] S1, When the water purifier turns on the chilled water function, the refrigeration device starts, and the cooling fan 3 starts synchronously;

[0032] S2, Determine whether the user is making ice water. If so, execute step S3; if not, execute step S4;

[0033] S3, The cooling fan 3 is turned off. After 5 seconds of completing the production of ice water, the cooling fan 3 is restarted and transferred to step S4;

[0034] S4, Determine whether the ice water temperature reaches the set temperature point. If not, continue to execute this step; if so, transfer to the next step;

[0035] S5, Turn off the refrigeration device, and the cooling fan 3 is turned off 30 seconds after the refrigeration device is turned off.

[0036] Reference Figures 1-3, in this embodiment, the air outlet part 12 is arranged on the top cavity wall of the water receiving cavity 11. The air outlet part 12 is composed of a plurality of air outlet holes arranged at intervals, and the air outlet holes can be any one of round holes, strip holes or special-shaped holes; the cooling fan 3 is detachably installed on the outer surface of the top of the water receiving cavity 11, so as to make full use of the space of the housing assembly 1 above the water receiving cavity 11. Refer to Figure 3 , when the refrigeration device generates heat during operation, the cooling fan 3 is turned on, and the air blows from top to bottom, extracting the hot air accumulated inside the housing assembly 1 from the front edge of the product outer door, so that the temperature inside and outside the product reaches equilibrium.

[0037] Furthermore, the air inlet part 13 and at least part of the refrigeration device are both arranged close to the water receiving cavity 11, so that the heat dissipation path can be shortened, facilitating the cooling fan 3 to quickly extract the heat generated by the operation of the refrigeration device out of the product, effectively improving the heat dissipation efficiency.

[0038] In this embodiment, the air inlet part 13 is arranged at the bottom of the housing assembly 1. The air inlet part 13 is composed of a plurality of air inlet holes arranged at intervals, and the air inlet holes can be any one of circular holes, rectangular holes, strip holes or special-shaped holes. The refrigeration device includes a compressor 21, a condenser 22, a condensing fan 23 and an evaporator (not shown in the figure). The condenser 22 is installed on the inner surface of the bottom of the housing assembly 1 and covers all of the air inlet part 13. The compressor 21 is arranged outside the condenser 22 and is connected to the evaporator through the condenser 22. The cooling fan 3 is installed on the condenser 22. The air suction port of the condensing fan 23 is connected to the air inlet part 13 through the condenser 22, and the air discharge port of the condensing fan 23 is connected to the inside of the housing assembly 1. In this way, through the condensing fan 23, the heat generated by the operation of the compressor 21 is blown from bottom to top, so that the heat accumulates at the top of the housing assembly 1 and is discharged through the cooling fan 3.

[0039] The refrigeration device further includes a fixing bracket 24. The fixing bracket 24 covers the outside of the condenser 22 from top to bottom and is connected to the bottom of the housing assembly 1. The compressor 21 is installed on the top of the fixing bracket 24, so that the compressor 21 is stacked directly above the condenser 22 through the fixing bracket 24. At this time, the compressor 21 and the condenser 22 are arranged at intervals in the height direction, with a reasonable layout, which is beneficial to reducing the occupied space. The cooling fan 3 is installed on the top of the condenser 22 and is located inside the fixing bracket 24. Ventilation openings 241 are provided on the top and / or side walls of the fixing bracket 24. The air discharge port of the condensing fan 23 is connected to the inside of the housing assembly 1 through the ventilation openings 241. In this way, the compressor 21, the condensing fan 23 and the condenser 22 are arranged at intervals in the height direction, with a reasonable layout, which is beneficial to reducing the occupied space. At the same time, the heat generated by the operation of the compressor 21 is blown from bottom to top, so that the heat accumulates at the top of the housing assembly 1.

[0040] Further, the water circuit system includes an ice water tank 41 and a water outlet nozzle 42. The water outlet nozzle 42 is disposed on the top cavity wall of the water receiving cavity 11. The ice water tank 41 is disposed inside the housing assembly 1 and is connected to the water outlet nozzle 42. The refrigeration device is used to make the water in the ice water tank 41 into ice water. In this embodiment, the evaporator of the refrigeration device is disposed on the ice water tank 41, and this evaporator is used to make the water in the ice water tank 41 into ice water.

[0041] In this embodiment, the ice water tank 41 is disposed on the side of the compressor 21 away from the water receiving cavity 11, so that the ice water tank 41 is away from the heat dissipation path, avoiding accelerating the heat convection on the outer surface of the ice water tank 41 during the heat dissipation process, and thus facilitating the reduction of the energy loss of the ice water tank 41. It should be particularly noted that a partition can be added between the ice water tank 41 and the compressor 21 to separate the ice water tank 41 from the compressor 21, thereby facilitating the reduction of the heat convection between the two.

[0042] The water circuit system further includes a fixed support 43 and a water pump 44. The fixed support 43 is disposed outside the side of the compressor 21 away from the water receiving cavity 11 and is connected to the bottom of the housing assembly 1. The ice water tank 41 is installed on the top of the fixed support 43. The water pump 44 is disposed inside the fixed support 43 and is connected to the ice water tank 41. At this time, the ice water tank 41 and the water pump 44 are arranged at intervals in the vertical direction, with a reasonable layout, which is conducive to reducing the occupied space.

[0043] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
