Embodiment approach 1

[0055] The following is based on Figure 1 to Figure 7 (b) One embodiment of the present invention will be described.

[0056] figure 1 It is an external appearance perspective view of the heater 1 which is the electric equipment which concerns on 1st Embodiment of this invention. figure 2 yes figure 1 The A-A line view section view. image 3 yes figure 1 The BB line view section view.

[0057] Such as Figure 1 to Figure 3 As shown, the heater 1 has an operating part 2 on the upper surface of the main body, a human sensor 3 and an air outlet 4 on the front of the main body, and a suction port 5 on the back of the main body. The operation unit 2 includes, for example, a switch for switching operation content such as blower operation or heating operation, a switch for switching operation intensity such as strong operation or weak operation, and the like. The human sensor 3 is located at the upper part of the front of the main body, and detects a human body to output ...

Embodiment approach 2

[0098] The following is based on Figure 8 ~ Figure 10 Other embodiments of the present invention will be described. In addition, for the convenience of description, the same reference numerals are assigned to components having the same functions as those described in the above-mentioned embodiments, and description thereof will be omitted.

[0099] Figure 8 It is a block diagram showing the configuration of each element of the air heater 1' according to the second embodiment. A passing judgment unit 36 ​​is added to the human body detection control unit 30' of the air heater 1'.

[0100] The passing determination unit 36 ​​determines that a person has passed by when a person is detected based on the detection signal only within a few seconds (the second predetermined time) within the last 8 seconds of the determination time T0. When passing is judged by the passing judgment unit 36, the operation time determination unit 34′ determines the operation ON time (absence determ...

Abstract

An electrical device is made in view of such problem, and the object, When people stop being truly unless people are, although people are, reducing the situation of carrying out an erroneous decision and stopping operation, as much as possible. A warm air machine (1) which is provided with a human body detecting part (20) and is controlled to be operated by determining human being presence or absence according detecting signals. A motion degree judgment part (32), the human detection within the latest determination time T0, the total time of owner is computed and the degree of a motion of people is judged based on this. A non-detection time measuring part (33) computes the non-detection time from the latest human detection since owner is detected continuously human detection owner is not detected according to the above signals. A presence / absence judgment part (35) is used for determining the presence and absence of human body thorugh comparing the above non-detection time and operation ON time. An operation-time deciding part (34) is used for determining the operation ON time according to the determination of the motion degree judgment part (32).

Description

technical field [0001] The present invention relates to an electrical device that stops or starts to operate by detecting the presence or absence of a person using a human detection sensor. Background technique [0002] Conventionally, pyroelectric sensors are generally used as human detection sensors in such electrical equipment. The electric equipment starts to operate based on the signal detected by the human detection sensor, and when the signal is not detected by the human detection sensor within a certain period of time, it is determined that the electric device does not exist, and the operation is stopped. [0003] However, a pyroelectric sensor is a sensor that detects a human body by virtue of human motion (movement of a heat source). Therefore, if the person does not move for a certain period of time, the presence of the person cannot be detected by the human detection sensor. As a result, even when the person does not move for a certain period of time, the elect...
