Description

Technical Field

[0001] The utility model relates to the technical field related to refrigeration equipment, and in particular to a protective cover for a temperature controller in a refrigerator. Background Art

[0002] The refrigerator thermostat is a control device used to control the temperature of the refrigerator. Since most thermostats are exposed in the refrigerator, and there are various other components, pipes or connecting wires inside the refrigerator in addition to the thermostat, the overall density is relatively high. This also causes the metal parts on the pipes and other components inside the refrigerator to easily approach or touch the thermostat pins, which also causes arcing near the thermostat pins, which may further cause fire incidents. In addition, as a refrigeration equipment, the refrigerator has a lot of humidity inside and is prone to condensation. The lack of protection for the thermostat is also prone to short circuit and fire after the condensed water drops onto the pins, posing a great safety hazard. For this reason, some thermostats are equipped with protective covers to isolate the thermostat from other components and to isolate condensed water.

[0003] However, the existing protective covers are generally divided into two types, one is a sealed protective cover, and the other is a protective cover with heat dissipation holes. However, the sealed protective cover will affect the heat dissipation of the thermostat, while the protective cover with heat dissipation holes is not comprehensive enough in protecting condensed water. In addition, other components inside the refrigerator will also generate heat. Setting heat dissipation holes on the protective cover cannot achieve a good heat dissipation effect. Therefore, it is necessary to propose a protective cover that can both provide closed protection for the thermostat and ensure heat dissipation of the thermostat. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a protective cover which can not only seal and protect the thermostat but also ensure the heat dissipation of the thermostat.

[0005] The utility model is implemented by the following technical scheme: a panel cover and a cover shell arranged on the panel cover, wherein a first ventilation frame and a second ventilation frame are respectively arranged in the cover shell, one end of the first ventilation frame and the second ventilation frame both penetrate the panel cover and extend to the outside of the cover shell, and two first guide plates and two second guide plates are arranged in the cover shell, the two first guide plates respectively correspond to the first ventilation frame and the second ventilation frame, the two first guide plates are both inclined toward one side of the panel cover, and the two second guide plates are inclined relative to each other, so that the outside wind entering the cover shell can form a circulation to smoothly bring out the heat in the cover shell, thereby further improving the heat dissipation effect of the thermostat when there is wind.

[0006] As a further improvement of the above solution, two rectangular openings are provided on the panel cover, and the first ventilation frame and the second ventilation frame respectively penetrate the corresponding rectangular openings and contact the corresponding inner walls of the rectangular openings.

[0007] As a further improvement of the above solution, a dustproof net is arranged in the first ventilation frame.

[0008] As a further improvement of the above solution, an extension groove is provided at one end of the first ventilation frame located in the cover shell.

[0009] As a further improvement of the above solution, a blocking cover is provided at one end of the second ventilation frame outside the cover, and a through opening is provided at the bottom of the blocking cover.

[0010] As a further improvement of the above solution, a side of the blocking cover facing away from the cover shell is sloped.

[0011] As a further improvement of the above solution, the panel cover is provided with convex ribs, and the cover shell is provided with positioning grooves matched with the convex ribs.

[0012] As a further improvement of the above solution, a threading hole is provided on one side of the cover shell, and a rubber ring is provided in the threading hole.

[0013] As a further improvement of the above solution, the two first guide plates are inclined at an angle of forty-five degrees toward one side of the panel cover, and the two second guide plates are inclined at an angle of forty degrees relative to each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The first ventilation frame and the second ventilation frame that penetrate the panel cover form a heat dissipation channel of the thermostat protective cover. Compared with the conventional heat dissipation structure design in which the heat dissipation holes are set on the inner wall of the protective cover, the heat dissipation structure directly passes through the panel cover to communicate with the outside world, which makes the thermostat not affected by the moisture inside the refrigerator, condensed water droplets, other components and heat emitted by other components, while ensuring heat dissipation;

[0016] By arranging two first guide plates and two second guide plates in the cover, when air from the outside enters the cover through the first ventilation frame, it can form a circulation along the thermostat in the cover and discharge the heat in the cover through the second ventilation frame, thereby making use of the wind from the outside to improve the heat dissipation effect of the thermostat in the cover.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Please combine Figures 1 to 5 , a protective cover for a thermostat in a refrigerator, comprising a panel cover 1 and a cover shell 3 arranged on the panel cover 1, wherein a first ventilation frame 4 and a second ventilation frame 7 are respectively arranged in the cover shell 3, and one end of the first ventilation frame 4 and the second ventilation frame 7 both penetrate the panel cover 1 and extend outside the cover shell 3, and two first guide plates 9 and two second guide plates 10 are arranged in the cover shell 3, and the two first guide plates 9 correspond to the first ventilation frame 4 and the second ventilation frame 7 respectively, and the two first guide plates 9 are inclined at a forty-five degree angle toward one side of the panel cover 1, and the two second guide plates 10 are inclined at a forty-degree angle relative to each other, so that the outside wind can enter the cover shell 3 to form a circulation to smoothly bring out the heat in the cover shell 3, so that the heat dissipation effect of the thermostat can be further improved when there is wind, and a fixing frame for fixing the thermostat is arranged on the panel cover 1, which enables the thermostat to be fixed to the panel cover 1 by screws, and four nut columns are arranged on the panel cover 1, and four connecting rings corresponding to the nut columns are arranged on the cover shell 3, so that the cover shell 3 can be connected to the panel cover 1 by screws.

[0026] Two rectangular openings 2 are provided on the panel cover 1 , and the first ventilation frame 4 and the second ventilation frame 7 respectively penetrate the corresponding rectangular openings 2 and contact the inner walls of the corresponding rectangular openings 2 .

[0027] Through the above technical solution, the two rectangular openings 2 are used as reserved openings of the panel cover 1, which allow the first ventilation frame 4 and the second ventilation frame 7 in the cover shell 3 to be connected to the outside world, thereby forming a heat dissipation channel to ensure the heat dissipation of the thermostat.

[0028] A dustproof net 5 is arranged inside the first ventilation frame 4 .

[0029] Through the above technical solution, in order to prevent external dust from entering the housing 3, the housing 3 can be isolated by the dustproof net 5, thereby ensuring ventilation and heat dissipation while isolating dust.

[0030] An extension groove 6 is provided at one end of the first ventilation frame 4 located in the housing 3 .

[0031] Through the above technical solution, due to the more complex external environment, water may splash into the first ventilation frame 4 and then flow into the cover 3 through the first ventilation frame 4. In order to avoid this situation, an extension groove 6 is provided on the first ventilation frame 4 to prevent water stains falling into the first ventilation frame 4 from flowing into the cover 3.

[0032] A blocking cover 8 is provided at one end of the second ventilation frame 7 outside the housing 3 , and a through opening is provided at the bottom of the blocking cover 8 .

[0033] Through the above technical scheme, when there is wind from the outside, that is, airflow blows into the cover 3, the blocking cover 8 blocks the second ventilation frame 7 to a certain extent, so that the second ventilation frame 7 cannot take in air and serves as an air outlet in the airflow circulation and heat dissipation, while the first ventilation frame 4 serves as an air inlet, so that when the wind from the outside blows, it enters the cover 3 from the first ventilation frame 4, and then circulates in the cover 3 and is discharged through the second ventilation frame 7, thereby avoiding the problem that the wind from the outside enters the cover 3 through the first ventilation frame 4 and the second ventilation frame 7 at the same time, resulting in the airflow in the cover 3 cannot be discharged, and when there is no wind outside, the blocking cover 8 will not limit the normal dissipation of heat in the cover 3, so that the first ventilation frame 4 and the second ventilation frame 7 can both be used as heat dissipation outlets under windless conditions.

[0034] The side of the blocking cover 8 facing away from the housing 3 is in a slope shape.

[0035] Through the above technical solution, the sloped structure has a guiding effect, so that the external airflow enters the cover 3, circulates once and is discharged through the second ventilation frame 7. After contacting the baffle cover 8, it can be smoothly discharged through the opening at the bottom of the baffle cover 8, thereby making the discharge of the airflow smoother.

[0036] The panel cover 1 is provided with a convex rib 11 , and the cover shell 3 is provided with a positioning groove 12 matched with the convex rib 11 .

[0037] Through the above technical solution, the convex rib 11 can be used as a positioning structure of the cover shell 3, and it cooperates with the positioning groove 12 to improve the sealing performance when the panel cover 1 and the cover shell 3 are combined.

[0038] A threading hole is provided on one side of the cover shell 3, and a rubber ring is provided in the threading hole.

[0039] Through the above technical solution, the threading hole makes the cover 3 not limit the temperature sensing line of the thermostat, so that it can extend normally to the outside of the cover 3, and the rubber ring can avoid the gap between the threading hole and the temperature sensing line.

[0040] The implementation principle of a protective cover for a temperature controller in a refrigerator in an embodiment of the present application is as follows:

[0041] The first ventilation frame 4 and the second ventilation frame 7 that penetrate the panel cover 1 form a heat dissipation channel of the thermostat protective cover. Compared with the conventional heat dissipation structure design in which the heat dissipation holes are set on the inner wall of the protective cover, the heat dissipation structure directly passes through the panel cover 1 to communicate with the outside world, so that the thermostat is not affected by the moisture inside the refrigerator, condensed water droplets, other components and heat emitted by other components, while ensuring its own heat dissipation;

[0042] When there is air flow from the outside, the external air flow enters the inside of the cover shell 3 through the first ventilation frame 4, and then when the air flow hits the first guide plate 9 at the top, it will go toward the second guide plate 10 at the top under the guidance of the first guide plate 9, and when the air flow hits the second guide plate 10 at the top, it will be guided to the second guide plate 10 at the bottom, and then guided by the second guide plate 10 to the first guide plate 9 at the bottom, and then discharged through the second ventilation frame 7 under the guidance of the first guide plate 9 at the bottom, so that the external air flow entering the cover shell 3 can form a circulation in the cover shell 3, so that when there is air flow from the outside, the heat in the cover shell 3 can be more easily discharged, thereby improving the heat dissipation effect of the thermostat.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
