A hinge pin 23 is vertically extended from the refrigerator body 2 and pivotally supports one end of the refrigerator compartment door 18. The refrigerator compartment door 18 rotates around the hinge pin 23 and can be opened and closed. The vegetable compartment door 19, the ice making compartment door 20, the switching compartment door 21, and the freezer compartment door 22 are drawer type doors that can be opened and closed by sliding in the forward direction.

  The refrigerator compartment door 18 is provided with a recess 24, and an operation unit 25 is disposed in the recess 24. In the case of the present embodiment, the operation unit 25 uses an electrostatic sensor 26, and a material obtained by applying a chromium plating to a plastic material such as an ABS resin is used. Note that the material of the operation unit 25 may be conductive, and an aluminum extrusion material, a stainless steel plate, or the like can also be used. At this time, the outer periphery 27 of the recess is disposed on the front side of the door with respect to the operation unit 25. Further, at least a part of the operation unit 25 is disposed on the substantially opposite side from the rotation axis centering on the hinge pin 23, that is, on the counter-rotation axis side with respect to the center line of the refrigerator compartment door 18. The arrangement height of the operation unit 25 is set in a range of 900 mm to 1300 mm from the floor surface.

  An operation means 28 is provided on the upper part of the refrigerator body 2 to operate the push rod 29. Although not shown, as the operation means 28, a motor-driven actuator or a solenoid-type drive device is used.

  A control unit 30 is provided on the back surface of the refrigerator main body 2, and the operation unit 25 and the control unit 30, and the control unit 30 and the operation means 28 are electrically connected.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when a hand touches the operation unit 25, the electrically connected control unit 30 determines contact detection based on a predetermined determination value. When it is determined that there is contact, an operation signal is sent to the operation means 28 which is also electrically connected. Upon receiving the operation signal, the operation means 28 drives the motor or solenoid, pushes the push rod 29 toward the refrigerating room door 18 and opens the refrigerating room door 18.

  At this time, the outer periphery 27 of the recess is arranged on the front side of the door with respect to the operation unit 25 and operates without any problem when the operation unit 25 is intentionally touched with a finger. In the case where a portion that is dimensionally larger than the width of the concave portion 24 comes into contact with the vicinity of the operation portion, it is possible to prevent the first contact with the outer periphery 27 of the concave portion and the direct contact with the operation portion 25.

  In addition, the operation part 25 may be provided in the partition part comprised between doors.

  The operation unit 25 is provided on the substantially opposite side to the rotation axis of the refrigerating room door 18, but is usually a position where a handle for opening and closing the door exists in the case of a conventional refrigerating room door. The door movement when touched can be easily analogized and predicted. If the operation unit 25 is provided only in the vicinity of the rotation axis, the door opening operation and the actual door operation are very unnatural, and the behavior is unexpected. Therefore, by arranging the operation unit 25 in this manner, an unintended door operation can be prevented.

  Moreover, although the operation part 25 is arrange | positioned in the range of 900 mm-1300 mm from a floor surface, this is that the distance from the floor surface of a standard Japanese woman (height 155 cm) to an elbow is 970 mm, This is set considering that the distance from the floor to the shoulder is 1265 mm. The lower limit dimension of 900 mm is a range that can be reached when a woman bends the elbow lightly, and lifting the arm above the shoulder is physically burdensome, so the upper limit dimension is set to 1300 mm, and the operating range 25 is disposed. It was determined.

  At this time, even if the operation unit 25 is arranged over almost the entire height of the refrigerator compartment door 18, it is possible to operate while reducing the physical burden. In this embodiment, however, the operation unit 25 has a conductive material such as a resin-plated product. If the size of the operation unit 25 is increased, cost increases unnecessarily. Therefore, the operation unit 25 is arranged in a range that is considered to be operated most frequently.

  Moreover, although the electrostatic sensor 26 is used for the operation part 25, the characteristic of an electrostatic sensor is that operation is possible with a very light touch feeling without being displaced at the time of operation. In the present embodiment, since a countermeasure for preventing malfunction is applied to the operation unit 25, the highly sensitive electrostatic sensor 26 can be used for the operation unit 25.

  As described above, in the present embodiment, the concave portion for disposing the operation portion is provided on the front surface of the refrigerator body, and the outer periphery of the concave portion is disposed on the front side of the door from the operation portion. However, direct contact with the operation unit can be prevented, and unintended door movement can be prevented. As a result, it is possible to prevent a situation where the operation is continued while the door is open and to maintain the freshness of the food. In addition, there is an effect of preventing the storage room from condensing with the door open.

  Moreover, in this Embodiment, by providing an operation part in a door, the arrangement | positioning location of an operation part can be recognized clearly, and the operation | movement of the door which is not intended can be prevented.

  Further, in the present embodiment, the door is a rotary type, and the operation part is provided on the substantially opposite side of the rotation shaft, so that it is easy to predict the door operation at the time of operation, and the unintended door operation is prevented. be able to.

  Moreover, in this Embodiment, the low-cost operation part can be provided, ensuring favorable operativity by setting the arrangement | positioning height from the floor surface of an operation part in the range of 900 mm-1300 mm. .

  In the present embodiment, since an electrostatic sensor is used for the operation unit, an operation signal can be generated simply by touching, and a good operational feeling can be obtained.

  In the present embodiment, the operation means for opening the door has been described. However, the present invention is not limited to the case of opening the door, and an operation means for performing the door closing operation may be used. As an operation means for performing the closing operation, for example, a geared motor (not shown) provided in the vicinity of the hinge pin 23 can be considered. Further, in the case of a drawer type door, a combination of a motor and a rack and pinion structure (not shown) is also conceivable.
