Description

  The present invention relates to a refrigerator having a function capable of easily removing dirt that is difficult to wipe off in a refrigerator.

In recent years, titanium oxide has been generally used as a conventional antifouling functional agent used in automobiles, home appliances, etc., with maintenance-free appeal. However, in order to support titanium oxide on the base material, a binder such as a silicon-based binder or an organic binder is required. If titanium oxide is not uniformly supported on the film surface, the activity is low, and a catalyst for titanium oxide. Damage to the binder due to the effect.

  Titanium oxide does not exhibit an active effect without irradiation of light (ultraviolet rays), and therefore does not exhibit an effect in a dark place such as a refrigerator. Therefore, in the case of a refrigerator, the photocatalyst is used only for external parts. (For example, refer to Patent Document 1).

  Hereinafter, the conventional refrigerator will be described with reference to the drawings.

FIG. 4 is a schematic cross-sectional view of a conventional refrigerator. As shown in FIG. 4, the conventional refrigerator includes a cooler 2, a cold air stirring fan 3, a defrosting heater 4, a door 5 for each room, a handle 6 for each room door, and a warehouse in the freezer compartment 1. Inside, it is comprised from the shelf 7 for warehouses, and the door shelf 8. FIG. Each room door 5 and each door handle 6 are coated with titanium oxide 9 on the surface.

  However, in the above conventional refrigerator, since titanium oxide cannot exhibit an activation effect without irradiation of light (ultraviolet rays), the antifouling function can be applied only to external parts. The effect is not exerted in places always in a dark atmosphere such as As a means for solving this, there is a method of installing an ultraviolet lamp in the cabinet, but in this case, there arises a problem that the resin components in the cabinet are deteriorated by the influence of ultraviolet rays. In addition, as a method of shortening the irradiation time of ultraviolet rays and reducing the effect on resin parts, by adding a phosphorescent-type ultraviolet radiation material to the photocatalyst material, the ultraviolet radiation effect of the phosphorescent material, There is a method of exhibiting the effect even in a dark place, but in this case as well, there is a problem that the resin component is deteriorated due to the influence of ultraviolet rays irradiated from the phosphorescent ultraviolet radiation material.

  The present invention solves the above-mentioned conventional problems, and by applying a hydrophilic coating agent to the internal parts, it exhibits the same effect as the antifouling function due to the hydrophilic action by ultraviolet irradiation of the photocatalyst, An object of the present invention is to provide a refrigerator that can easily clean its surface even when food is attached, and can keep the inside environment for storing food clean.

  In order to solve the above-mentioned problems, the refrigerator of the present invention applies a hydrophilic coating material mainly composed of a titania phosphate to the shelf and door shelves of the refrigerator, and the hydrophilicity of the photocatalyst by ultraviolet irradiation. It exhibits the same effect as the antifouling function due to sexual action, and even if oil-based foods are adhered, the surface can be easily cleaned with water wiping, and the environment in which the food is stored can be kept clean.

  According to the refrigerator of the present invention, the hydrophilic coating material mainly composed of a titania phosphate compound is applied to the refrigerator shelf and the door shelf, and the antifouling due to the hydrophilic action by ultraviolet irradiation of the photocatalyst is applied. Even if oil-based foods adhere, the surface can be easily cleaned by wiping with water, and the internal environment for storing foods can be kept clean.

  The invention of the refrigerator according to claim 1 is such that a hydrophilic coating material mainly composed of a titania phosphate compound is applied to a shelf part and a door shelf part of the refrigerator, and the hydrophilic action by ultraviolet irradiation of the photocatalyst. The same effect as the antifouling function is exhibited, and even if oil-based foods are attached, the surface can be easily cleaned by wiping with water, and the internal environment for storing foods can be kept clean.

  In addition to the invention described in claim 1, the refrigerator invention described in claim 2 is more antifouling in the refrigerator by applying a hydrophilic coating material mainly composed of a titania phosphate compound to the inner wall surface. The range of functions can be expanded, and the environment in which the food is stored can be kept clean.

  In addition to the invention of claim 1 or 2, the invention of the refrigerator according to claim 3 keeps the interior environment for storing food more clean by applying a hydrophilic coating material having an antibacterial effect. Can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, about the same structure as the past, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted. Further, the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic cross-sectional view of a refrigerator according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the refrigerator of the present embodiment includes a cold air inlet 2, a cold air stirring fan 3, a defrosting heater 4, a door 5 for each room, and a handle for each room door. 6 and the inside of the cabinet are composed of a cabinet shelf 7 and a door shelf 8. Further, the interior shelf 7 and the room door shelf 8 of each room are covered with a hydrophilic coating agent 10. The hydrophilic coating agent used here is a titanium phosphate compound or a condensate thereof.

  The film of this hydrophilic coating agent has a water contact angle value of 5 to 10 °. Therefore, even if a liquid seasoning having oil stored in the refrigerator door shelf is spilled on the surface, it can be easily wiped with water. Dirt can be wiped off. As a result, generation of microorganisms such as soot can be prevented in advance.

(Embodiment 2)
FIG. 2 is a schematic cross-sectional view of a refrigerator according to Embodiment 2 of the present invention.

  The surface of the refrigerator inner wall surface portion 11 is coated with the hydrophilic coating agent 10. Note that by applying this hydrophilic coating agent to the refrigerator inner wall surface portion, it is difficult to reach and wipe the inner surface of the refrigerator inner wall. Oil-based dirt adhering to the location can be easily wiped off. As a result, generation of microorganisms such as soot can be prevented in advance.

(Embodiment 3)
FIG. 3 is a schematic cross-sectional view of a refrigerator according to Embodiment 3 of the present invention.

  The refrigerator door 5 for each room, the handle 6 for each room door, and the inner wall surface 11 are coated with a hydrophilic antibacterial coating agent 12. In addition, this hydrophilic antibacterial coating agent is composed of a compound mainly composed of a titania phosphate compound, and by applying it to the target location, it is difficult to reach the inner surface of the inside of the cabinet and oil that adheres to the location that is difficult to wipe off. The anti-bacterial agent that has antibacterial action and that uses antibacterial silver and gold is environmentally friendly and does not affect the human body. The growth of bacteria can be reduced, and the generation of microorganisms such as sputum can be prevented.
