With reference to the contents shown in FIGS. 1 and 8, the first embodiment of the present invention provides a lid 100 for an ice box, and the lid 100 for the ice box is refrigerated in order to realize sealing of the entire ice box. The purpose is to cover the opening of the main body of the ice box. The lid 100 of the refrigerating box and the main body of the refrigerating box may have a separate structure independent of each other, for example, both of which are detachably connected to each other. When the icebox lid 100 is detachably connected to the icebox body, if the icebox does not need to be sealed in order to achieve sealing of the entire icebox, remove the icebox lid 100 from the icebox body. If the icebox needs to be sealed, the icebox lid 100 can be attached to the icebox body.

As shown in FIGS. 1 and 2, the lid 100 of the ice box includes the first lid 10 and the second lid 20, and also has a cold insulation component between the first lid 10 and the second lid 20. 30 are arranged.

Among them, the method of arranging the cold insulation component 30 includes, but is not limited to, the following two possible implementation forms.

One possible implementation is to place a first groove on the side surface of the first lid 10 close to the cold insulation component 30 (not shown) and a second on the side surface of the second lid 20 close to the cold insulation component 30. Grooves are arranged (not shown) and the cold insulation component 30 is arranged in a space surrounded by a first groove and a second groove.

Specifically, as shown in FIG. 4, the cold insulation component 30 includes an outer case 301 and an inner case 302 arranged inside the outer case 301, of which the inside of the refrigerating box is frozen inside the inner case 302. A cold insulating agent for this purpose is stored, and the refrigerant can be stored in the gap 303 between the outer case 301 and the inner case 302.

To explain, the ice pack is a translucent or opaque viscous gelatinous mixture composed of organic and / and inorganic compounds that absorbs and stores large amounts of cold heat at low temperatures and releases large amounts of cold heat at high temperatures. You can keep yourself and the low temperature environment within a small area around you for a long time.

The refrigerant is a refrigerating device that operates in an indirect cooling system, and is a substance that transfers the heat to be cooled to the evaporating refrigerating agent. Refrigerants are usually liquids and generally do not undergo a phase change during heat transfer. However, some refrigerants are gas or liquid and solid mixtures, such as binary ice.

As one optional embodiment, the inner case 302 and the outer case 301 are detachably connected. As a result, the inner case 302 is taken out in advance and placed in another freezing facility for pre-cooling. At the time of use, the pre-cooled inner case 302 is placed in the outer case 301, and the inner case 302 is cooled by the refrigerant. The cooling time of the inner case 302 can be shortened.

The liquid outlet 3012 is for allowing the heat-exchanged refrigerant to flow out of the outer case 301.

As one optional embodiment, the first lid 10 and / or the second lid 20 may be a heat insulating member. Since the lid 100 of the refrigerating box is a heat insulating lid, it is possible to prevent the cold heat from being released to the outside from the refrigerant in the lid 100 of the refrigerating box, thereby guaranteeing the freezing effect of the thing in the refrigerating box.

Illustratively, the material of the first lid 10 and / or the second lid 20 may be an EPP material.

As a matter of explanation, EPP is an abbreviation for expanded polypropylene, which is an abbreviation for new foamed plastic. Specifically, EPP refers to polypropylene plastic foam material, which is a highly crystalline polymer / gas composite material, which is recyclable and reusable, can be decomposed naturally, and has no risk of plastic pollution. A new, rapidly growing, environmentally friendly compression cushioning insulation.

Outflows from the outer case 301 from the liquid discharge pipe 402, and the other end of the liquid-filled pipe 401 and the other end of the liquid discharge pipe 402 lead to the outside of the lid 100 of the refrigerating box.

When specifically used, as shown in FIG. 7, by connecting the liquid inlet 3011 to the liquid inlet pipe 401 and the liquid outlet 3012 to the liquid discharge pipe 402, the low temperature refrigerant can be supplied from the liquid inlet 3011. It flows into the gap 303 between the outer case 301 and the inner case 302 and flows out of the outer case 301 from the liquid outlet 3012, whereby the inner case 302 can be frozen, and after the inner case 302 is cooled, the liquid inlet The 3011 and the liquid outlet 3012 may be separated from the liquid-filled pipe 401 and the liquid discharge pipe 402, respectively. Since freezing is realized and the cold insulating agent is stored in the inner case 302, the cold insulating agent can transfer the stored cold heat to the refrigerant, thereby extending the freezing time and improving the freezing effect.

In this embodiment, the lid 100 of the refrigerating box also includes a ventilation pipe 50, an air inlet 3013 and an air outlet 3014 are arranged on the outer case 301, and the ventilation pipe 50 penetrates the inside of the cold insulation component 30. Both ends of the ventilation pipe 50 communicate with the air inlet 3013 and the air outlet 3014, respectively, and the air inlet 3013 is for supplying a cooling air flow into the ventilation pipe 50. The outlet 3014 is for the heat-exchanged cooling air flow to flow out.

As an explanation, the hollow arrow in FIG. 7 indicates the direction of the flow of the refrigerant, and the solid arrow indicates the direction of the flow of the cooling air flow.

As a result, cold air is introduced into the ventilation pipe 50 and transmitted to the inner case 302 along the ventilation pipe 50. In this embodiment, a fan 60 is driven so that cold air is transported along a ventilation pipe 50, as compared to a conventional method that relies solely on natural air flow to dissipate cold heat. Adopted to further improve the freezing speed.

In this embodiment, as shown in FIG. 8, the mounting groove 202 is arranged on the side surface of the second lid 20 opposite to the first lid 10, and the mounting groove 202 adapts to the opening edge of the ice box body. Thereby, the sealing between the lid 100 of the refrigerating box and the main body of the refrigerating box is realized.

It can be understood that a refrigerating box body having a similar opening edge is possible even if the refrigerating box body has a different shape or size, and therefore, when the cold storage component 30 is arranged on the lid 100 of the refrigerating box, the said The mounting groove 202 of the icebox lid 100 can be simultaneously adapted to various icebox bodies having different shapes and sizes, which greatly improves adaptability to different icebox bodies.

Further, the shape surrounded by the mounting groove 202 in the embodiment of the present invention may be round, square, polygon, or the like, whereby the ice box body 100 is adapted to the ice box body having different opening edges. To be able to.

By arranging the 202, it is possible to adapt to a refrigerating box body having a different opening edge, an arbitrary shape and an arbitrary size.

As a description, the embodiments of the present invention do not limit the shape and size of the mounting groove 202, and are not limited to the above examples.

Further, as shown in FIGS. 4 and 6, the quick connector 80 may be arranged at one end of the liquid inlet pipe 401 away from the liquid inlet 3011 and one end of the liquid discharge pipe 402 away from the liquid outlet 3012. This makes it easy for the liquid-filled pipe 401 and the liquid-draining pipe 402 to be directly and quickly connected to other pipes communicating with the outside.

A quick connector is a connector that can connect or disconnect pipes without tools. Illustratively, the quick connector 80 in the embodiment of the present invention includes a quick connector for air, a quick connector for oxygen fuel gas, a quick connector for gas and liquid, a quick coupling for hydraulic pressure, a quick connector for inert gas, and a cooling water hot oil. It may be a quick connector for a fuel, a semiconductor quick connector, or the like.
