Description

Washing machine with local prewash function

Technical field

The invention belongs to the field of cleaning equipment, and particularly relates to a washing machine with a partial pre-washing function.

Background technique

In real life, people often need to perform special treatments on parts when cleaning clothes, such as collars and cuff positions in shirts. It is difficult to completely clean the dirt in these places unless special local cleaning is used in advance; Other local stains such as lipstick marks, oil stains, and wine stains also need to be cleaned separately. At present, the washing machines on the market cannot be partially pre-washed, and the washing effect on stubborn stains is poor. However, if the hands are laborious and hurt the clothes, the detergent will easily cause environmental pollution and other disadvantages.

Ultrasonic cleaning is the use of ultrasonic cavitation in the liquid (water molecule blasting), acceleration and direct flow to the liquid and dirt directly and indirectly, so that the dirt layer is dispersed, emulsified, peeled to achieve the purpose of cleaning . The current ultrasonic cleaning needs to be transmitted in a liquid in order to achieve the effect of cleaning the object to be cleaned. In the prior art, the ultrasonic cleaning technology uses an ultrasonic cleaning machine as a container, and the components to be cleaned are immersed therein, and the purpose of cleaning is achieved under the action of ultrasonic waves.

However, unlike the stains on the surface of rigid items, which are prone to vibration and drop, clothing is generally made of various fibers, which has a soft texture and has the effect of absorbing ultrasonic waves. The ultrasonic washing device has a large loss of ultrasonic waves when washing clothes; Generally, the washing device uses a high-frequency ultrasonic cleaning device issued by an ultrasonic transducer to vibrate the liquid in the cleaning tank to generate many tiny high-frequency air bubbles. These small air bubbles constantly hit the surface of the clothes being washed, and the stains on the surface of the clothes being washed. , Oil stains and other resonance, so that stains, oil stains fall off. For cloths such as clothing, the stains of cotton products are adsorbed inside, or have penetrated into their molecular or atomic tissues. High-frequency air bubbles can only cause resonance on the surface of the clothing. The laundry placed directly in the washing tank has a limited cleaning effect, and it is even less ideal for local stubborn stains.

Application document 201410354696.8 discloses a solution for assisting laundry using an ultrasonic generator. This solution additionally provides a washing tank on the cover plate of the washing machine. Due to the large volume of the washing tank, the space of the washing machine is excessively occupied. When the cleaning tank is used for ultrasonic cleaning, it is not convenient to take out large pieces of laundry in the washing tub, which is extremely inconvenient to use, and the ultrasonic sounding device can be directly seen on the workbench of the washing machine. The function of ultrasonic washing, but affects the overall appearance of the washing machine, and is not conducive to the protection of the ultrasonic sounding device.

Example 1

As shown in Figures 1-6, the object of the present invention is to provide a washing machine with a partial prewash function. The washing machine includes an ultrasonic washing device; the ultrasonic washing device includes an ultrasonic generating device 6 connected to each other and a washing tank 7 located at a lower portion of the ultrasonic generating device 6, and the two are connected to each other through a rotatable connection device 5. The ultrasonic washing device is rotatably connected to the control panel base 1 of the washing machine through the rotatable connection device 5. The control panel base 1 has a receiving space 3 for receiving the ultrasonic washing device. As shown in Figs. 1 and 3, the ultrasonic washing device is provided in the accommodation space 3 in a rotatable manner.

The ultrasonic washing device adopts the ultrasonic washing method to independently perform the pretreatment or laundry washing of the clothes; the accommodation space 3 is used to conceal the ultrasonic washing device on the washing machine. The rotatable connection device 5 in this embodiment is connected to the bottom surface of the accommodation space 3, and the ultrasonic generating device 6 can rotate around the rotatable connection device 5 so as to be rotated in / out from the accommodation space opening 9 The accommodation space 3.

As shown in the figure, the accommodating space 3 is recessed from the upper surface of the control panel base 1 and is located between the clothing input port 2 of the control panel base 1 and the outer peripheral wall 4 of the control panel base. The side wall of 3 is opened to the laundry input port 2, and the ultrasonic washing device is screwed into / out of the storage space through the storage space opening 9.

Preferably, the rotatable connection device 5 in this embodiment is a rotating shaft connection device connected to the bottom surface of the receiving space 3.

In order to enable the ultrasonic washing device to be hidden after being screwed into the accommodating space 3, the width of the ultrasonic generating device 6 in this embodiment is not greater than the width of the accommodating space 3. The width of the accommodating space 3 refers to the accommodating space. The distance between the accommodation space opening 9 of the space and the side wall of the accommodation space 3 opposite the opening. Such a design makes the ultrasonic generating device 6 fully screwed into the accommodating space 3, and does not cause any blocking to the clothing insertion opening 2, and meets the requirements of the laundry machine for placing large pieces of clothing. Further, the total width of the ultrasonic washing device including the cleaning tank 7 is smaller than the width of the accommodating space 3, thereby improving the shielding effect of the equipment.

In order to further optimize the hiding effect of the accommodating space 3 on the ultrasonic washing device, as shown in FIG. 5, the height of the ultrasonic washing device is not higher than the height of the sidewall of the accommodating space. The ultrasonic washing device does not affect the opening and closing of the upper cover of the washing machine, and can completely cover the ultrasonic washing device when the upper cover of the washing machine is closed. Thus, the integrity of the appearance of the washing machine is guaranteed.

As shown in FIG. 1, FIG. 3 and FIG. 6, the ultrasonic washing device is provided with a limited position and a working position according to a positional relationship between the ultrasonic generating device and the storage space. As shown in FIG. 3, when the ultrasonic generating device 6 is fully screwed into the accommodating space 3, the ultrasonic washing device is in a limiting position; as shown in FIG. 1 or FIG. 6, when the ultrasonic generating device 6 is After rotating around the rotatable connection device 5 and at least rotating out of the accommodating space 3, the ultrasonic washing device is in a working position. The ultrasonic washing device provides a local pre-wash function for laundry when in the working position.

When the rotatable connection devices of the ultrasonic washing device are located on the left and right side walls of the control panel base, the rotation angle of the ultrasonic washing device when switching from the limit position to the working position is not more than 180 degrees.

However, as shown in the figure of this embodiment, when the rotatable device is disposed at one corner of the control panel seat of the washing machine, the angle of rotation of the ultrasonic washing device when switching from the limit position to the working position is not greater than 90 degrees.

As shown in FIGS. 1, 3, and 6, the clothes insertion opening 2 of the control panel base of this embodiment is located in the middle of the control panel base 1 whose cross-section outer edge is a quadrilateral, and the control panel 8 of the washing machine is installed. On the control panel base 1 and close to one side of the quadrilateral, the outer peripheral wall corresponding to the side is the first side; the accommodation space is located on the control panel base opposite and / or adjacent to the first side. Between the outer peripheral wall and the clothing insertion opening. That is to say, the placement position of the ultrasonic cleaning device is placed inside the tray seat on the side other than the side where the control panel is located. This is because there are many control wires or interfaces in the side wall space where the control panel is located. The space is very limited, which is not conducive to providing accommodation space for the ultrasonic washing device. At the same time, from the perspective of convenience, the arrangement of the rotatable device in any one of the two corners of the control panel base near the back plate as in the present invention can make the accommodation space set in the control On the upper surfaces of both sides of the disk base and the back side, the relatively large installation space at the corners of the disk base is fully utilized, thereby making the installation structure more compact.

Example 2

This embodiment is a supplement to Embodiment 1. As shown in FIGS. 1 to 5, this embodiment discloses a washing machine with a partial pre-wash function using a control panel seat of the washing machine according to Embodiment 1. The washing machine includes an ultrasonic washing device as in Embodiment 1. The control panel base 1 has an accommodating space 3 accommodating the ultrasonic washing device, and the ultrasonic washing device is rotatably provided in the accommodating space 3. Inside.

The washing bucket and the ultrasonic washing device of the washing machine of this embodiment can work independently. The washing bucket is used to wash the entire piece of large-scale laundry. The ultrasonic washing device is mainly used to clean some parts of the clothing that are not easily cleaned. Such as collars, cuffs, clothing edges, etc., pretreatment or separate ultrasonic washing, can also be used to clean local stains on clothing or soft materials in order to achieve the effect of quickly removing stubborn stains.

The washing machine in this embodiment may be any kind of washing machine such as a drum washing machine, a pulsator washing machine, and a double drum washing machine.

For convenience of description, this embodiment is described by using a pulsator washing machine as an example:

The ultrasonic generating device 6 in this embodiment is fixedly connected to the cleaning tank 7 through a rotatable connection device 5. The cleaning tank 7 moves integrally with the ultrasonic generating device 6 and maintains a fixed relative position relationship with each other. As shown in FIG. 1 to FIG. 5, the ultrasonic cleaning device is provided with a limited position and a working position according to a positional relationship between the ultrasonic generating device 6 and the storage space 3. As shown in FIG. 3, when the ultrasonic generating device 6 is fully screwed into the accommodating space 3, the ultrasonic cleaning device is in a limiting position; as shown in FIG. 1 or FIG. 6, when the ultrasonic generating device is around After the rotatable connection device is rotated and at least rotated out of the accommodating space, the ultrasonic washing device is in a working position that provides ultrasonic pre-washing of clothes.

In the washing machine of the present invention, the ultrasonic washing device is concealed and installed on the washing machine. When not in use, it is hidden in the accommodating space of the control panel seat of the washing machine. The appearance of the washing machine is complete, and there is no ultrasonic washing device. The ultrasonic cleaning device is turned out to expose the ultrasonic generating device 6 and the cleaning tank 7 and perform ultrasonic cleaning. In this way, the integrity of the appearance of the washing machine can be maintained, and the obstruction and influence on the normal washing of the washing machine can be avoided, which is convenient for users.

In a further solution, the ultrasonic washing device includes an ultrasonic generating device 6 and a washing liquid cleaning tank 7 for containing washing liquid. The ultrasonic generating device 6 has an ultrasonic generating device that generates vibrations, and the ultrasonic generating device faces the cleaning tank 7; The device 6 and the cleaning tank 7 are rotatably installed on the control panel base 1 through a rotatable connection device 5 so as to be rotated out for ultrasonic washing or retracted and hidden according to the needs of use.

After at least part of the laundry to be washed is placed between the ultrasonic generating device 6 and the washing tank 7, the laundry to be wetted by the washing liquid in the washing tank 7, may be completely wetted or partially wetted; the top surface of the laundry after washing is soaked In contact with the ultrasonic generating device of the ultrasonic generating device 6, when the ultrasonic generating device 6 is working, the stains of the laundry to be resonated with the ultrasonic generating device, and at the same time, the resonance can reach the deep layers of the clothing fibers, and the stubborn stains on the surface of the clothes and the deep layers can follow the ultrasonic The vibration wave is dropped due to resonance, so the effect of removing stains is better.

The clothes do not need to be completely immersed in the washing tank 7, they only need to contact the ultrasonic generating device of the ultrasonic generating device 6 to reach resonance after soaking, so as to achieve the effect of thorough cleaning. Since this solution only needs to soak the clothes and does not need to place the ultrasonic generating device in the liquid to generate resonance, only a small amount of liquid is needed, the required washing tank 7 is also shallow, and its depth only needs to be greater than the thicker clothes. Therefore, the volume requirement of the cleaning tank 7 is very small, and only a small amount of water is needed to achieve a good cleaning effect, which can save space and greatly save water consumption, and the cleaning process is convenient and fast.

The ultrasonic generating device of the ultrasonic generating device 6 is in contact with the liquid surface in the washing tank 7 or has a certain distance. The interval is such that when the upper surface of the laundry to be in contact with the ultrasonic generating device, at least the lower surface of the laundry to be in contact with The level of the washing liquid is in contact.

The liquid level of this solution can be a fixed level liquid level reached after the washing liquid enters the cleaning tank 7, and the height of the liquid level can be set according to the size of the cleaning tank 7.

When the ultrasonic generating device of the ultrasonic generating device 6 is in contact with the liquid surface in the washing tank 7, the laundry to be fully wetted in the cleaning tank 7, and the upper surface of the laundry to be in contact with the ultrasonic generating device. When the ultrasonic generator 6 is working, the ultrasonic vibration directly reaches the clothes, which reduces the consumption of ultrasonic waves. At the same time, the high-frequency ultrasonic waves it emits vibrate the liquid infiltrated in the laundry, generating many tiny high-frequency bubbles. These small bubbles are constantly hitting. The surface and the inner layer of the laundry are resonated with the stains on the surface and the inner layer of the laundry to cause the stains to fall off.

When the ultrasonic generating device of the ultrasonic generating device 6 and the liquid surface in the washing tank 7 have a certain distance, the distance needs to be the largest when the upper surface of the laundry to be in contact with the ultrasonic generating device, the lower surface of the laundry and the washing liquid Liquid level contact. In this way, it can ensure that the laundry to be infiltrated with the washing liquid continuously, so as to achieve resonance during the ultrasonic operation, and achieve the effect of cleaning.

Two working positions.

This setting enables the ultrasonic generator to have more new options when pre-washing clothes. When there is a large piece of clothing, the ultrasonic generator can be placed in the second working position through the rotation of the rotatable connection device. At this time, the ultrasonic generating device 6 and the washing tank 7 are staggered from each other, so that the pre-washing operation of such clothes can be more conveniently processed.
