Patent Description:
Generally, a blender is referred to as a mixer or crusher, and is mainly used for crushing or chopping food contained in a container body by rotating blades by the rotation of a motor.

In a normal blender, a main body having a motor operated by electricity is located at the lower side of the blender. The container body for receiving food is seated on the upper side of such a main body. Blades for crushing or chopping food are provided inside the container body, and are rotated by the rotational force of the motor.

Accordingly, when a user drives the motor by using a manipulation button or a knob of the main body after putting food in the container body, the blades receiving the rotational force generated by the motor crush or chop food contained inside the container body.

Various types of blenders have recently been developed in accordance with a user's desire to facilitate the food intake of office workers due to their busy daily life. That is, a small hand blender has been developed, and a slightly larger blender has been developed that allows food to be crushed in a large capacity or at high speed.

Furthermore, a vacuum blender which cuts or crushes food by vacuumizing the inside of the container body is also disclosed such that a food material received in the container body of the blender can be processed in a fresher state.

However, each of the various types of blenders is provided with electronic parts such as a motor assembly and at least one PCB module for controlling the operation of the blender. Furthermore, during the operation of the blender, heat is generated in the motor assembly or the PCB module, and malfunction thereof may occur.

In addition, as for a manipulation part composed of a touch button, a PCB provided under the manipulation part is moved, and thus the manipulation sensitivity of the manipulation part is decreased, and manipulation thereof is not accurately sensed and performed. That is, in in <CIT> or <CIT>, a manipulation panel provided under a display part which is manipulated by a user or displays is not securely held, and thus the manipulation of the display part by a user is not accurately transmitted to the manipulation panel or a manipulation error thereof occurs. Additionally, due to the sagging of an outer casing, malfunction of the blender may occur.

<CIT> relates to a blender which comprises: a jar in which a blade module is placed; a body in which the jar is seated and which has an opened lower surface; a motor assembly inside the body for rotating the blade module; a cooling fan at the lower end of a rotary shaft of the motor assembly and rotating when the motor assembly is driven to force air flow in the inside of the body; a PCB module placed between the circumferential surface of the body and the motor assembly; a base plate which blocks the opened lower surface of the body and includes a plate suction port via which air is sucked into the inside of the body, and a plate drain port via which air is discharged to the outside of the body; and an air guide which connects the motor assembly to the plate drain port to thereby form a discharge path of air, wherein the PCB module is placed at the upper side of the plate suction port and is cooled by the sucked air.

The support means <NUM> may function to block the downward movement of the touch module <NUM>. That is, the support means <NUM> may be provided under the touch module <NUM> and may prevent the touch module <NUM> from sagging or moving downward when a user presses or touches the touch manipulation part <NUM>. Accordingly, due to the prevention of the downward movement of the touch module <NUM>, when a user presses or touches the touch manipulation part <NUM>, the signal of the touch manipulation part <NUM> may be accurately received and transmitted to the touch module <NUM>, and a user's touch feeling may be improved.

The touch module <NUM> may be held by the PCB holder <NUM>, and the support means <NUM> may be provided under the PCB holder <NUM>. That is, as illustrated in <FIG>, the PCB holder <NUM> having the shape of a flat plate having predetermined size and thickness may be provided under the touch module <NUM> and the display module <NUM> (above the touch module <NUM> and the display module <NUM> in <FIG> and <FIG>), and the touch module <NUM> and the display module <NUM> may be placed to be supported on the upper surface of such a PCB holder <NUM> (on a lower surface thereof in <FIG> and <FIG>).

The PCB holder <NUM> may be coupled to the inner casing <NUM>. That is, the PCB holder <NUM> may be configured to be mounted to the lower part of the upper surface of the inner casing <NUM> by at least one screw (an upper part thereof in <FIG> and <FIG>).

The support means <NUM> may be provided on an end of the heat dissipation frame <NUM> which fixedly supports the heat dissipation member <NUM> provided inside the main body <NUM>. More specifically, as described above, the heat dissipation frame <NUM> may be installed to cover the upper and lower ends of the heat dissipation member <NUM> and may fixedly support the heat dissipation member <NUM>, and the support means <NUM> may be provided on the upper end of the front end part of such a heat dissipation frame <NUM>.

As illustrated in <FIG>, the support means <NUM> may be formed by protruding sideward or upward from the upper end of the heat dissipation frame <NUM>, and such a support means <NUM> may be installed to have an upper end in close contact with the lower surface of the PCB holder <NUM>.

As illustrated in <FIG>, at least one groove may be formed in the support means <NUM>. That is, at least one groove which is depressed may be formed on the upper surface of the support means <NUM>, or at least one groove recessed inward from a side surface of the support means <NUM> may be formed on the upper surface of the support means <NUM>. Accordingly, when the groove is formed in the support means <NUM>, the support means <NUM> may be decreased in weight and material cost while supporting the PCB holder <NUM>.

In addition, the support means <NUM> may include at least one rib. That is, as illustrated in <FIG>, the support means <NUM> may be provided with at least one rib protruding upward, and such a rib may be configured to have an upper end in contact with the PCB holder <NUM>.

Furthermore, a support member <NUM> may be provided under the upper surface of the main body casing <NUM> such that the sagging of the main body casing <NUM> is prevented even when the upper surface of the main body casing <NUM> is pressed by a user.

<FIG> illustrates a bottom cutaway perspective view of a state in which the right portion of the main body <NUM> is partially cut. As illustrated in the drawing, the support member <NUM> which prevents the sagging of the main body casing <NUM> may be provided under the upper surface of the main body casing <NUM> constituting the exterior of the main body <NUM>.

Even when the upper surface of the main body casing <NUM> is pressed by a user, the one or more support member <NUM> may prevent the sagging of the main body casing <NUM>, and thus the malfunction of the touch manipulation part <NUM> may be prevented.

As illustrated in <FIG>, the support member <NUM> may include at least one rib.

Meanwhile, as described above, the main body casing <NUM> may be composed of the inner casing <NUM> and the outer casing <NUM> provided respectively at inner and outer sides thereof, and the support member <NUM> may be configured to support the upper surface of the inner casing <NUM>.

More specifically, as illustrated in <FIG>, the support member <NUM> may be provided between the heat dissipation frame <NUM> which fixedly supports the heat dissipation member <NUM> provided inside the main body <NUM> and the inner casing <NUM>. So the support member <NUM> may be mounted on the heat dissipation frame <NUM> to be provided between the heat dissipation frame <NUM> and the lower surface o the inner body casing.

Accordingly, when the inner casing <NUM> is securely supported by the support member <NUM>, the overall upper surface of the main body casing <NUM> may be naturally prevented from sagging since the outer casing <NUM> is in contact with the inner casing <NUM>.

In addition, as illustrated in <FIG>, the lower end of the heat dissipation frame <NUM> may be in contact with the base plate <NUM>, and the base plate <NUM> may be in contact with the base end <NUM>. Accordingly, the associated parts may be connected to each other to be in contact with each other from the upper surface of the main body casing <NUM> to the base end <NUM>, so the upper surface of the main body casing <NUM> may be prevented from being pressed or sagging. Accordingly, the malfunction of the blender may be completely prevented.

Hereinafter, the operation of the blender of the present disclosure having the above configuration will be described with reference to the accompanying drawings.

When the container body <NUM> is seated on the main body <NUM>, the blender is in a state of <FIG>, and in this state, the use of the blender of the present disclosure starts.

First, in order for a user to use the blender, power supply from the outside may be required, and this power supply may be wirelessly performed by the wireless power module <NUM>. That is, power supply from the outside may be performed in a method of using an induced electromotive force, and of course, power supply may be performed by wire.

The power of the wireless power module <NUM> may be supplied to parts which require power, such as the motor assembly <NUM>, the touch manipulation part <NUM>, and the power transmission means <NUM>, and a user may manipulate the starting or stopping of the blender by manipulating the touch manipulation part <NUM> or the knob <NUM>.

For example, when a user is intended to start crushing food by manipulating the touch manipulation part <NUM> or the knob <NUM>, the motor assembly <NUM> may be required to be operated to rotate the blades of the blade assembly <NUM>.

However, in this case, the detection system may determine whether the container lid <NUM> is closed, and when the container lid <NUM> is opened, the motor assembly <NUM> and the blade assembly <NUM> may not operate.

Specifically, since the reed switch <NUM> is normally turned off, the power reception means <NUM>, the reed switch <NUM>, and the light transmission module <NUM> may not form a closed circuit in the container body <NUM>, and thus the light reception means <NUM> may not receive light.

Accordingly, when the light reception means <NUM> does not receive light, due to such a signal, the supply of power to the motor assembly <NUM> may be blocked.

In this state, when the container lid <NUM> is closed, the permanent magnet <NUM> of the container lid <NUM> may approach the reed switch <NUM>, and thus the reed switch <NUM> may be turned on. Accordingly, the power reception means <NUM>, the reed switch <NUM>, and the light transmission module <NUM> may formed a closed circuit, so the light reception means <NUM> may receive light generated by the light transmission module <NUM>.

In this case, the closing of the container lid <NUM> may be detected, and according to the manipulation of a user, the operation of the motor assembly <NUM> may start and food inside the container body <NUM> may be crushed. Of course, in this case, the mounting of the container body <NUM> to the main body <NUM> may be detected by the container body detection switch <NUM>, and the operation of the motor assembly <NUM> may start.

In addition, in this case, the operation state of the blender of the present disclosure may be displayed through the display part <NUM> to the outside, and thus a user may visually recognize the operation state or time of the blender.

Meanwhile, when a user opens or closes the container lid <NUM> of the container body <NUM>, the user may open or close the container lid <NUM> by gripping the upper half part of the cap <NUM> with the hand. The container lid <NUM> may be in close contact with and held on the upper surface of the container body <NUM> by a user pushing the container lid <NUM> downward from a side above the container lid <NUM>. In this case, a gap between the container lid <NUM> and the container body <NUM> may be covered by the gasket <NUM> provided on the outer surface of the container lid <NUM>.

Furthermore, the cap <NUM> mounted to the center portion of the container lid <NUM> may be removed therefrom by a user, and this is possible when a user grips the upper end of the cap <NUM> and rotates the cap <NUM> as described above.

When the cap <NUM> is removed from the container lid <NUM>, a user may insert food into the container body <NUM> through the lid hole <NUM>, and may control food inside the container body <NUM> with a rod passing through the lid hole <NUM>.

Due to the operations of the motor assembly <NUM> and the blade assembly <NUM>, food contained inside the container body <NUM> may be crushed or mixed and the work intended by a user may be completed. In this case, a user may move the container body <NUM> upward from the main body <NUM> to be removed therefrom, and then may open the container lid <NUM> to take out food contained inside the container body <NUM>.

In addition, according to the operation of the motor assembly <NUM>, the cooling fan <NUM> connected to the lower end of the motor shaft <NUM> may rotate.

When the cooling fan <NUM> rotates, external air may be introduced into the main body <NUM> and then may be discharged back to a side under the main body <NUM>.

Specifically, according to the rotation of the cooling fan <NUM>, external air of the side under the main body <NUM> may be introduced upward along the air introduction hole <NUM> formed in a position adjacent to the right end of the base end <NUM>.

The external air introduced along the air introduction hole <NUM> may flow upward along the air introduction guide hole <NUM> of the base plate <NUM> and may pass through and exchange heat with the PCB module (the inverter PCB module <NUM>) and the heat dissipation member <NUM> provided above the base plate <NUM>. That is, the PCB module (the inverter PCB module <NUM>) and the heat dissipation member <NUM> may exchange heat with external air to be cooled.

Next, the external air may be collected in the center of the inner upper side of the main body <NUM>, and may be introduced through the housing holes <NUM> formed in the upper surface of the motor housing <NUM> into the motor assembly <NUM>.

The air introduced into the motor assembly <NUM> may exchange heat with the coil of the inside of the motor <NUM> so as to cool the motor <NUM>, and continuously may be discharged to the lower side of the motor assembly <NUM> and may be introduced into the air guide <NUM>.

Air discharged laterally from the inside of the air guide <NUM> by the cooling fan <NUM> may flow to the left of the air guide <NUM>, and may pass through the air discharge guide hole <NUM> formed in a position adjacent to the left end of the base plate <NUM> to flow downward, and continuously, may pass through the air discharge hole <NUM> formed in a position adjacent to the left end of the base end <NUM> to be discharged to a side under the main body <NUM>.
