Abstract

Proposed is a blender which detects whether a container lid is closed by transmitting an electrical signal through a transparent film. The blender according to the present disclosure comprises a container body in which food is accommodated; a main body provided under the container body so as to support the container body; the container lid detachably mounted on the upper surface of the container body so as to open and close the upper side of the container body; and a detection system which detects whether the container lid is mounted on the container body, wherein the detection system includes a transparent electrode film configured to have multiple layers so as to guide the flow of electricity. Therefore, the blender has the advantage of preventing an assembly defect without damaging the appearance of the container body formed of a transparent material.

First claim

The invention claimed is:

1 . A blender comprising:
a container body in which food is accommodated; a main body to support the container body; a container lid detachably mounted on an upper surface of the container body so as to open and close the upper surface of the container body; and a detection system which detects whether the container lid is mounted on the container body, wherein the detection system comprises a transparent electrode film to guide a flow of electricity, the transparent electrode film having multiple layers, the transparent electrode film comprising a transmission member which transmits the flow of electricity, and a base film on which the transmission member is provided.

2 . The blender of claim 1 , wherein the transparent electrode film comprises a cover film provided at one side of the transmission member, which covers the transmission member.

3 . The blender of claim 2 , comprising a fixing member which allows the transparent electrode film to be fixed to the container body.

4 . The blender of claim 3 , wherein one surface of the fixing member is in contact with one surface of the cover film.

5 . The blender of claim 2 , wherein the transparent electrode film comprises an adhesive member provided between the transmission member and the cover film such that the transmission member and the cover film are coupled to each other.

6 . The blender of claim 1 , wherein the transparent electrode film comprises a coating layer formed on an end of the transmission member so as to prevent corrosion of the end of the transmission member.

7 . The blender of claim 1 , wherein the transparent electrode film is a single integral member configured such that a first end of the transparent electrode film is connected with a second end of the transparent electrode film with no break in between.

8 . The blender of claim 1 , wherein the transparent electrode film comprises a main part attached to the container body, a first bent part formed by bending and extending from a first end of the main part, and a second bent part formed by bending and extending from a second end of the main part.

9 . The blender of claim 8 , comprising a support part provided at the first bent part so as to supplement resistance against external force.

10 . The blender of claim 9 , wherein the support part protrudes from the first bent part.

11 . The blender of claim 10 , wherein the support part includes a tear prevention groove to prevent damage or tearing of the support part due to bending between the main part and the first bent part.

12 . The blender of claim 9 , comprising a reinforcement piece provided on one side of the support part so as to supplement rigidity of the support part.

13 . The blender of claim 1 , comprising a reinforcement piece provided at the transparent electrode film so as to supplement rigidity of the transparent electrode film.

14 . The blender of claim 1 , wherein an end of the transparent electrode film is coupled to an end part of the container body by a hook fastener.

15 . The blender of claim 14 , wherein the end of the transparent electrode film comprises a hook groove in which a hook of the hook fastener is inserted.

16 . The blender of claim 1 , wherein the transmission member is printed on the base film.

17 . The blender of claim 16 , wherein the transmission member is formed from a silver paste material.
