Patent Description:
The present disclosure generally relates to a blender, more particularly, to a blender, wherein a blender body operates when closure of a container lid is detected.

<CIT> describes a blending system that includes a base that is selectively and operatively engaged with a container. The base may include a near field communications chip that may communicate with a near field communications chip of a cutting disc. The cutting disc identifies a type of the cutting disc, a position of a chute of a lid or both.

<CIT> describes a food processing apparatus which is for simplifying a structure by connecting safety devices using a contactless method for detecting temperature of a container or a combination state of the container with a main body. A food processing apparatus comprises a container, a main body, safety devices, and a control unit.

<CIT> describes a kitchen device including: a base having a mechanism that is operated using electrical power to cause processing of food; a vessel removably mounted on the base and including a bottom wall, a side wall extending upwardly from the bottom wall to a rim so as to provide a space to receive the food to be processed, with the rim surrounding an opening to the space; a lid removably coupled to the rim so as to at least partially close the opening; and an interlock system operatively associated with the mechanism to permit the delivery of the electric power to the mechanism, the system including a first interlock circuit and a second interlock circuit, wherein delivery of the electric power to the mechanism is permitted by the completion of the first interlock circuit and activation of the second interlock circuit.

Generally, a blender is a household appliance that chops or crushes food received in a container body by blades rotated by an electric motor.

In such a blender, the container body is seated on the upper surface of a blender body in which the motor is provided, and when the container body is seated, the blades provided in the container body are connected to a rotating shaft of the motor, and are then rotated.

After a user puts food inside the container body through an open portion of the container body and closes a lid thereof, the user drives the motor by manipulating the blender body to rotate the blades so that food is crushed.

The container lid closes the open portion of the container body to protect food inside the container body. For safety during operation of the blender, the blades are not rotated when the container lid does not close the container body. That is, to prevent accidents due to the blades, the blades are preferably allowed to be rotated only when closure of the container lid is detected.

Conventional methods of detecting the closure of the container lid have been variously proposed.

For example, in prior arts, a push rod physically connecting the container body with the blender body is provided, and when the container lid closes the container body, the container lid presses the push rod. A press detection part of the blender body detects the press, and detects the closure of the container lid.

However, the push rod and the press detection part are required to be separately installed, and the press detection part may be contaminated due to moisture or food that may enter the press detection part.

In addition, the push rod of the container body and the press detection part of the blender body are required to be installed at positions corresponding to each other, so there is a problem that the container body is required to be mounted only in a specific direction.

Furthermore, the push rod is required to be installed along the container body in the longitudinal direction thereof from the container body to the blender body, so the design of the transparent container body is spoiled.

Recently, in order to solve this problem, a technique of detecting the closure of the container lid by the blender body by using wireless communication or electromagnetic coupling between the container body and the blender body has been disclosed.

For example, in <CIT>, when the container lid closes the container body, a blender detecting the closure of the container lid by the blender body by using a wireless communication module is disclosed.

However, in such a prior art, the wireless communication module is required, and a separate power supply is required to be provided in the container body so as to drive the wireless communication module.

In <CIT> an interlocking blending device is disclosed, wherein a transmitting coil and a receiving coil are arranged in a blender body, and a receiving coil and a transmitting coil are arranged in a container body so as to correspond to the transmitting coil and receiving coil, respectively, and when the container lid closes the container body, power is transmitted to the receiving coil of the container body through the transmitting coil of the blender body, and in turn, the power is transmitted to the receiving coil of the blender body through the transmitting coil of the container body, so that the blender body detects the closure of the container lid.

However, in such a prior art, two coils, that is, the transmitting coil and the receiving coil, are required to be installed in each of the blender body and the container body, and a device analyzing power received by the receiving coil of the blender body is required.

Additionally, two coils are arranged in each of the blender body and the container body, and when electric current flows through each coil, induced currents change due to interference between magnetic fields induced in the coils. Accordingly, it is difficult to accurately analyze power received by the receiving coil of the blender body.

Furthermore, power is transmitted from the transmitting coil of the blender body to the receiving coil of the container body, and, due to the closure of the container lid, the power is transmitted from the transmitting coil of the container body to the receiving coil of the blender body. In order to allow the receiving coil of the blender body to receive effective power, high power is required to be transmitted from the transmitting coil of the blender body to the receiving coil of the container body.

In addition, to electrically connect a container lid detection circuit with the blender body, a conductive member is installed along the transparent container body, and thus the design of the transparent container body is spoiled.

The inductive coupling may be selectively performed between the first inductive coil <NUM> and the second inductive coil <NUM> under a specific condition.

When the intensity of an electric current applied to the first inductive coil <NUM> changes, the magnetic field in the first inductive coil <NUM> is changed, and a magnetic flux passing through the second inductive coil <NUM> is changed due to the inductive coupling between the first inductive coil <NUM> and the second inductive coil <NUM>, so an induced electromotive force may be generated in the second inductive coil <NUM>.

The positions and arrangement of the first and second inductive coils <NUM> and <NUM> may be determined such that the inductive coupling is appropriately performed therebetween.

The container body <NUM> may include the transmission module <NUM> provided at the second side of the lower portion thereof, the transmission module transmitting a signal to the outside. In the embodiment, the transmission module <NUM> may be provided at the side of the lower surface of the second coil PCB module <NUM>.

The light source may include an LED light source, and the light sensor may be embodied as a semiconductor device, a photodiode, or a phototransistor, etc..

The detection module <NUM> may be provided on the upper end portion of the container body <NUM>. In the embodiment, the detection module <NUM> may be provided between the outer container body <NUM> and the inner container body <NUM> on the upper end portion of the container body <NUM>. The detection module <NUM> may be embodied in the form that the switch 151a to be described later is mounted to the PCB substrate.

The triggering member <NUM> may be provided at a side of the side surface of the container lid <NUM>. When the container lid <NUM> is closed on the container body <NUM>, the triggering member <NUM> may be arranged to approach the detection module <NUM> within a predetermined distance at height substantially equal to the height of the detection module <NUM>.

The switch 151a of the detection module <NUM> can be turned on when the container lid <NUM> is closed on the container body <NUM> and the triggering member <NUM> of the container lid <NUM> approaches within a predetermined distance. Accordingly, the detection module <NUM> can perform the function of detecting the closure of the container lid.

In the embodiment, the triggering member <NUM> may be a magnetic material, and the switch 151a may be a reed type switch.

In the embodiment, the reed switch is maintained to be initially off, and then can be turned on when the magnetic material approaches the reed switch within the predetermined distance.

The detection module <NUM> and the second coil PCB module <NUM> can be connected to each other by the conductive member <NUM> made of a transparent material. Specifically, the conductive member <NUM> of a transparent material can electrically connect the switch 151a of the detection module <NUM> to the second inductive coil <NUM> of the second coil PCB module <NUM>.

In the embodiment of the present disclosure, the conductive member <NUM> may include the transparent electrode film (ITO). The transparent electrode film (ITO) is a transparent material, and may be a material that can conduct electric current.

The transparent electrode film (ITO) may be provided at various positions. As in this embodiment, the transparent electrode film may be provided between the outer container body <NUM> and the inner container body <NUM>. Preferably, the transparent electrode film may be attached to the inner surface of the outer container body <NUM> or to the outer surface of the inner container body <NUM>.

For another example, the transparent electrode film (ITO) may be attached to the outer surface of the outer container body <NUM>. In this case, the transparent electrode film (ITO) is coated with a transparent coating material so that the transparent electrode film is protected from the outside.

The transparent electrode film (ITO) may be arranged in the longitudinal direction of the container body <NUM> from the detection module <NUM> of the upper portion of the container body <NUM> to the second coil PCB module <NUM> of the lower portion of the container body <NUM>. Due to the application of such a transparent electrode film (ITO), the transparency of the container body <NUM> of a transparent material can be maintained.

Meanwhile, the second inductive coil <NUM>, the switch 151a, and the transmission module <NUM> are electrically connected in series to each other. Accordingly, the supply of power from the second inductive coil <NUM> to the transmission module <NUM> according to the turning on/off of the switch 151a can be performed and stopped.

In this case, when power is supplied from the second inductive coil <NUM> to the transmission module <NUM>, a conversion module <NUM> may be selectively included to convert the power into power or signal form which can be used in the transmission module <NUM>. The conversion module <NUM> may be mounted to the second coil PCB module <NUM>.

When the transmission module <NUM> uses power generated from the second inductive coil <NUM> as it is, the conversion module <NUM> may not be arranged. In the embodiment, the conversion module <NUM> converts an alternating current voltage generated in the second inductive coil <NUM> into a direct current voltage required for the transmission module <NUM>, and supplies the direct current voltage.

<FIG> is a view illustrating an example of the equivalent circuit diagram of the blender of <FIG>, and <FIG> is a view illustrating another example of the equivalent circuit diagram of the blender of <FIG>.

Referring to the drawings, in the blender body <NUM>, the first inductive coil <NUM> may be connected to the power supply <NUM>, and the receiving module <NUM> may be connected to the controller <NUM> and the motor <NUM>.

The power supply <NUM> supplies an electric current to the first inductive coil <NUM>, and the magnetic field may be formed in the first inductive coil <NUM> by the supplied electric current.

The intensity of the electric current supplied to the first inductive coil <NUM> from the power supply <NUM> is controlled, so the change of the magnetic field of the first inductive coil <NUM> can be induced.

In the container body <NUM>, the second inductive coil <NUM> may be connected to the detection module <NUM> and the transmission module <NUM>. The second inductive coil <NUM> may be connected to the transmission module <NUM> and the detection module <NUM> selectively through the conversion module <NUM>.

In this case, in the embodiment, the connection between the second inductive coil <NUM> and the detection module <NUM> may be performed by the conductive member <NUM> of a transparent material.

The detection module <NUM> may include the switch 151a. In the embodiment, such a switch 151a may include the reed switch.

The operation of the blender will be described by an equivalent circuit diagram.

When the container lid <NUM> is not closed on the container body <NUM>, the detection module <NUM> does not detect the triggering member <NUM>, and the switch 151a is maintained to be turned off.

When the switch 151a is turned off, the second inductive coil <NUM>, the switch 151a, and the transmission module <NUM> do not form a closed circuit, so the inductive coupling is not performed between the first inductive coil <NUM> and the second inductive coil <NUM>.

When the container lid <NUM> is closed on the container body <NUM>, the triggering member <NUM> is in the state of approaching the detection module <NUM> within a predetermined distance, and the switch 151a can be turned on by the triggering member <NUM>.

When the switch 151a is turned on, a closed circuit can be formed between the second inductive coil <NUM>, the switch 151a, and the transmission module <NUM>, which are connected to each other in series.

Accordingly, when the closed circuit is formed, the inductive coupling is performed between the first inductive coil <NUM> and the second inductive coil <NUM>, and power induced in the second inductive coil <NUM> can be supplied to the transmission module <NUM>.

The transmission module <NUM> can transmit a signal to the outside according to the supply of the power. Accordingly, the receiving module <NUM> may receive the signal transmitted by the transmission module <NUM>.

As illustrated in the drawings, as required, the power induced in the second inductive coil <NUM> is selectively converted to power required for the transmission module <NUM> by the conversion module <NUM>, and the converted power can be supplied to the transmission module <NUM>.

<FIG> are views in which the position of the conversion module <NUM> is illustrated differently.

When the receiving module <NUM> receives a signal, the signal can be transmitted to the controller <NUM>. The controller <NUM> can drive the motor <NUM> only when the closure of the container lid is detected due to the reception of such a signal.

Accordingly, in the embodiment, in the state of the opening of the container lid, the receiving module <NUM> cannot receive the signal, so the controller <NUM> does not drive the motor <NUM>. The receiving module <NUM> can receive the signal only in the state of the closure of the container lid, so the controller <NUM> can drive the motor <NUM>.

Accordingly, the blender <NUM> may be allowed to be operated only under the specific condition of the closure of the container lid.

<FIG> is a detailed circuit diagram of <FIG>. Referring to <FIG>, the power supply <NUM> according to the embodiment of the present disclosure may include at least one of a filter <NUM>, a regulator <NUM>, an oscillator <NUM>, and an inverter <NUM>.

The filter <NUM> can remove noise included in Vdc input from the power supply (not shown) inside the blender body <NUM>, and the Vdc from which noise is removed can be input to the inverter <NUM>. In the embodiment, the filter <NUM> can output 12Vdc.

The regulator <NUM> outputs the Vdc by converting the Vdc output from the filter <NUM> into a lower Vdc. In the embodiment, the regulator <NUM> outputs the Vdc by lowering 12Vdc to 5Vdc.

The oscillator <NUM> can generate a pulse for an AC signal with respect to the DC voltage output from the regulator <NUM>. In the embodiment, the oscillator <NUM> can generate a pulse of <NUM>.

The inverter <NUM> can change the Vdc output through the filter <NUM> into an alternating current (AC) voltage by turning on/off of the switch according to the pulse of the AC signal, and supply the AC current to the first inductive coil <NUM>.

In the embodiment, the AC current is applied to the first inductive coil <NUM>, and the magnetic field formed in the first inductive coil <NUM> is changed. Due to the change of the magnetic field, the inductive coupling is performed between the first inductive coil <NUM> and the second inductive coil <NUM>.

The conversion module <NUM> may include a rectifier <NUM> and an LDO part <NUM>.

The rectifier <NUM> may convert the AC power induced in the second inductive coil <NUM> into DC power.

When the DC power output from the rectifier <NUM> is unstable due to various factors, the LDO part <NUM> stabilizes the output DC power, and supplies the stabilized DC power to the transmission module <NUM>. In this embodiment, the LDO part <NUM> may control such that the actual output value of DC power follows a reference output value.

The transmission module <NUM> can transmit the signal to the outside with the received DC power.

The switch 151a of the detection module <NUM> can open and close the circuit between the second inductive coil <NUM> and the transmission module <NUM>. The power induced in the second inductive coil <NUM> can be transmitted to the transmission module <NUM> only when the switch 151a is turned on.

A capacitor <NUM> and the first inductive coil <NUM> of the power supply <NUM>, and capacitors <NUM> and <NUM> and the second inductive coil <NUM> of the conversion module <NUM> can constitute a resonator.

<FIG> is a flowchart illustrating the process of detecting the closure of the container lid by the blender body according to the embodiment of the present disclosure.

Referring to <FIG>, in the embodiment, when the container lid <NUM> is closed on the container body <NUM> at S101, the switch 151a of the detection module <NUM> can be turned on by the triggering member <NUM> provided inside the side surface of the container lid <NUM> at S103.

When the switch 151a is turned on, the switch 151a, the second inductive coil <NUM>, and the transmission module <NUM> forms a closed circuit, and the inductive coupling can be performed between the first inductive coil <NUM> and the second inductive coil <NUM> at S105.

Due to such inductive coupling, power can be generated in the second inductive coil <NUM> at S107, and the generated power can be supplied to the transmission module <NUM> at S109.

The transmission module <NUM> can transmit a signal by using the supplied power at S111, and the receiving module <NUM> can receive the signal at S113.
