DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 A waste heat utilization device for a refrigerator shown in the figure comprises:

[0026] A collecting hood 1, a through opening 2 is opened on one side of the collecting hood 1, a heat-insulating pipe 3 is fixedly connected to the opening of the side through opening 2 of the collecting hood 1, and a fan 4 is fixedly installed inside the heat-insulating pipe 3;

[0027] The heat exchange device includes an insulation bin 5 and a heat conducting bin 9. The bottom of the insulation bin 5 is fixedly connected with a bottom plate 6. The end of the insulation pipe 3 away from the collecting cover 1 passes through and is fixedly connected to the lower side of the insulation bin 5. The upper side of the side of the insulation bin 5 is fixedly connected with an exhaust pipe 7. The top of the insulation bin 5 is fixedly connected with an annular cover 8. The outer side of the heat conducting bin 9 is fixedly connected with a guide plate 10. The outer side of the guide plate 10 is fixedly connected to the inner wall of the insulation bin 5. The upper and lower sides of the outer walls of the insulation bin 5 and the heat conducting bin 9 are respectively passed through and fixedly connected with a water inlet pipe 12 and a water outlet pipe 13. After the hot air enters the insulation bin 5, the heat is transferred to the heat conducting bin 9 to heat the water inside the heat conducting bin 9 and utilize the waste heat.

[0028] Furthermore, the guide plate 10 is in the shape of a spiral plate, so that the hot air can flow upward in a spiral, thereby prolonging the contact time with the heat transfer chamber 9 and improving the heat exchange effect.

[0029] Furthermore, a socket 11 is provided on the top of the heat-conducting bin 9, and an upper cover 16 is movably installed on the top of the heat-conducting bin 9. A plug rod 17 is fixedly connected to the bottom of the upper cover 16. The plug rod 17 is slidably inserted into the inner wall of the socket 11. The bottom of the upper cover 16 fits the top of the heat-conducting bin 9. The upper cover 16 covers the heat-conducting bin 9 to keep warm and is detachable.

[0030] Furthermore, a fixing rod 15 is fixedly connected to the top of the upper cover 16, a motor 14 is fixedly connected to the top of the fixing rod 15, a connecting shaft 18 is fixedly connected to the output shaft end of the motor 14, a paddle 19 is fixedly connected to the surface of the connecting shaft 18, and the connecting shaft 18 passes through the middle part of the upper cover 16 for rotation. The connecting shaft 18 and the paddle 19 rotate to stir the water in the heat transfer chamber 9, so that the heat distribution is more uniform, thereby improving the heating effect.

[0031] Furthermore, connecting plates 20 are fixedly connected to both sides of the collecting hood 1, pillars 21 are fixedly connected to the bottom of the connecting plates 20, and supporting plates 22 are fixedly connected to the bottom of the pillars 21. The pillars 21 and the supporting plates 22 play a role of lifting and supporting.

[0032] Furthermore, the cross-sectional shape of the collecting hood 1 is a right-angled trapezoid, and after the hot air enters the collecting hood 1 , it can be gathered in the upper area inside the collecting hood 1 , so that the fan 4 can be easily inhaled.

[0033] Furthermore, the interface between the insulation pipe 3 and the insulation chamber 5 is located below the guide plate 10 , and after the hot air enters the insulation chamber 5 , it starts to spirally rise from the bottom of the guide plate 10 .

[0034] Through the above technical solution:

[0035] Cold water is transported into the heat transfer bin 9 through the water inlet pipe 12, and the collecting hood 1 is placed above the refrigerator. The pillars 21 and the support plates 22 play a supporting and lifting role. The heat of the refrigerator body is discharged and rises into the collecting hood 1, and then is concentrated on the upper side of the collecting hood 1 and is sucked into the insulation pipe 3 by the fan 4. The hot air is discharged through the insulation pipe 3 to the area below the guide plate 10 on the lower side of the inside of the insulation bin 5, and then the hot air spirally rises along the surface of the guide plate 10. During the rising process, it fully contacts the heat transfer bin 9 and conducts the heat to the heat transfer bin 9 to heat the water inside the heat transfer bin 9. The motor 14 is turned on to drive the connecting shaft 18 and the paddles 19 to rotate, so as to stir the water inside the heat transfer bin 9, so that the heat distribution in the water is more even, thereby improving the efficiency of heat conduction. As a result, when the hot air flows to the top of the guide plate 10, most of the heat has been transferred to the water in the heat transfer chamber 9, the air temperature drops sufficiently, and then is discharged to the external environment through the exhaust pipe 7, which will not affect the external temperature and make full use of the heat. This solves the problem that most of the existing refrigerators directly dissipate the heat of the main body to the external air, resulting in increased temperature and reduced comfort of the working environment, and the heat is wasted and not environmentally friendly. When hot water is needed, the valve of the water outlet pipe 13 is opened, and the hot water in the heat transfer chamber 9 flows out through the water outlet pipe 13 for use. The upper cover 16 covers the heat transfer chamber 9 to play a role of heat preservation, and the upper cover 16 can be removed from the heat transfer chamber 9, which is convenient for cleaning the inside of the heat transfer chamber 9 and the connecting shaft 18 and the paddle 19.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
