Description

Technical Field

[0001] The present invention relates to the technical field related to electrical equipment, and in particular to a door washing mechanism and a washing device with bottom air intake and drying. Background Art

[0002] There are many different types of washing machines. For example, most washing machines have a single drum for washing and / or drying, and do not have a separate washing chamber for washing single or small pieces of clothing. Of course, some manufacturers have proposed washing machines with door-type washing chambers that can independently wash single or small pieces of clothing, but these only provide simple washing functions and do not provide further comprehensive technical solutions.

[0003] As a result, although the washing machine has the function of door washing, when washing is performed in the door structure, there is still the problem of poor washing effect and no drying function. Summary of the Invention

[0004] The main purpose of the present invention is to provide a door washing mechanism and a washing device with bottom air inlet and drying, so as to solve the problem that the washing devices in the prior art have poor cleaning effect and no drying function.

[0005] To achieve the above objectives, according to one aspect of the present invention, a door washing mechanism and a washing device with bottom air inlet and drying are provided. The door washing mechanism with bottom air inlet and drying comprises a door structure having a door washing chamber; an air duct structure having an air outlet communicating with the door washing chamber and located at the bottom of the door washing chamber; and a heating assembly mounted within the air duct structure.

[0006] Furthermore, the air inlet of the air duct structure is higher than the air outlet in the height direction of the door structure.

[0007] Furthermore, the heating component is close to the bottom of the door washing cavity relative to the top of the door washing cavity in the height direction of the door structure.

[0008] Furthermore, the duct structure includes a duct body, the duct body has an air outlet, the heating component is arranged inside the duct body, and the heating component and the air inlet end of the duct body are spaced apart so that a waterless pipe section is formed between the heating component and the air inlet end; a fan, the fan is arranged at the air inlet end of the duct body and supplies air into the duct body, and the heating component and the fan are located at both ends of the waterless pipe section.

[0009] Furthermore, the air duct body extends along the circumference of the door structure to form an arc-shaped tubular structure.

[0010] Furthermore, the distance between the air inlet end of the air duct body and the top of the door structure is smaller than the distance between the air inlet end of the air duct body and the bottom of the door structure.

[0011] Furthermore, the door washing mechanism with bottom air inlet drying also includes a driving member, which is installed inside the electrical cavity of the door structure; a pulsator, which is arranged inside the door washing cavity, and the driving member is connected to the pulsator, and the driving member drives the pulsator to move to stir the laundry inside the door washing cavity.

[0012] Furthermore, the door washing mechanism with bottom air inlet drying also includes a bracket, which is arranged inside the door washing cavity and above the air outlet of the air duct structure; a drain outlet is also provided on the door structure, which is connected to the door washing cavity and is located below the bracket, and the bracket is located below the impeller.

[0013] According to another aspect of the present invention, a washing device is provided. The washing device includes a complete machine having an opening and an outer drum washing chamber connected to the opening; and a door washing mechanism, the door washing mechanism being openably and closably disposed at the opening and being the aforementioned bottom-inlet drying door washing mechanism.

[0014] Furthermore, the washing device is a washing machine or a washer-dryer.

[0015] Applying the technical solution of the present invention, the washing device includes a complete machine and a door washing mechanism with bottom air inlet and drying. The complete machine has an outer drum washing chamber. The outer drum washing chamber and the chamber of the door washing mechanism with bottom air inlet and drying cooperate to form two independent chambers. Both independent chambers can be used for washing and drying. When there is no water in the door washing chamber, the air duct structure can work so that the wind in the air duct structure is heated by the heating component and blown into the door washing chamber from the air outlet, thereby drying the laundry in the door washing chamber; if there is no laundry in the door washing chamber at this time, the heated gas can also dry the water vapor in the door washing chamber, thereby avoiding the breeding of bacteria. When there is water in the door washing chamber and the air duct structure is working, the wind in the air duct structure can be heated by the heating component and blown into the door washing chamber from the air outlet, thereby performing hot bubble washing on the laundry in the door washing chamber, thereby improving the cleaning effect. Of course, if there is water in the door washing cavity and the air duct structure does not supply air into the door washing cavity, under the action of gravity, the washing water in the door washing cavity will flow back into the air duct structure through the air outlet of the air duct structure. When the water level reaches a certain condition, the heating component is used to heat the water, which can quickly dissolve the detergent and quickly remove stains on clothes, thereby enhancing the washing effect and improving the washing efficiency.

DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0028] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0029] In order to solve the problem that the washing device in the prior art has poor washing effect and no drying function, the present invention provides a door washing mechanism and a washing device with bottom air inlet and drying. The washing device can be used for industrial washing as well as household washing.

[0030] like Figures 1 to 7 As shown, the washing device includes a complete machine 1100 and a door washing mechanism. The complete machine 1100 has an opening and an outer drum washing chamber 1110 connected to the opening. The door washing mechanism is openably and closably arranged at the opening. Among them, the door washing mechanism is the door washing mechanism with bottom air intake and drying described below.

[0031] Specifically, the washing device is a washing machine or a washer-dryer.

[0032] Furthermore, the washing machine is a drum washing machine.

[0033] Of course, the washing device may also be a dishwasher or other similar products for washing laundry.

[0034] like Figures 1 to 3 As shown, the door washing mechanism with bottom air inlet drying includes a door structure, an air duct structure 500 and a heating component 700. The door structure has a door washing cavity 1020; the air outlet 530 of the air duct structure 500 is connected to the door washing cavity 1020, and the air outlet 530 is located at the bottom of the door washing cavity 1020; the heating component 700 is installed inside the air duct structure 500.

[0035] Specifically, the washing device includes a complete machine 1100 and a door washing mechanism with bottom air intake and drying. The complete machine 1100 has an outer drum washing chamber 1110. The outer drum washing chamber 1110 and the cavity of the door washing mechanism with bottom air intake and drying cooperate to form two independent chambers, and both independent chambers can be used for washing and drying. When there is no water in the door washing chamber 1020, the air in the air duct structure 500 is heated by the heating component 700 and blown into the door washing chamber 1020 through the air outlet 530, thereby drying the laundry in the door washing chamber 1020; if there is no laundry in the door washing chamber 1020 at this time, the heated gas can also dry the water vapor in the door washing chamber 1020, thereby preventing the growth of bacteria. When there is water in the door washing cavity 1020 and the air duct structure 500 is working, the air in the air duct structure 500 can be heated by the heating component 700 and blown into the door washing cavity 1020 through the air outlet 530, thereby performing hot bubble washing on the laundry in the door washing cavity 1020, thereby improving practicality. Of course, if there is water in the door washing cavity 1020 and the air duct structure 500 does not supply air to the door washing cavity 1020, under the action of gravity, the washing water in the door washing cavity 1020 will flow back into the air duct structure 500 through the air outlet 530 of the air duct structure 500, so that when the water level reaches a certain condition, the heating component 700 is used to heat the water, which can quickly dissolve the detergent and quickly remove stains on the clothes, thereby enhancing the washing effect and improving the washing efficiency.

[0036] It should be noted that the door structure also has an electrical cavity 1010 isolated from the door washing cavity 1020 , and the air duct structure 500 is arranged inside the electrical cavity 1010 .

[0037] like Figures 1 to 6 As shown, the air inlet of the air duct structure 500 is higher than the air outlet 530 in the height direction of the door structure.

[0038] Specifically, air enters from the air inlet of the air duct structure 500 and enters the door washing cavity 1020 along the air duct structure through the air outlet 530. At the same time, the air inlet is higher than the air outlet 530 to prevent water from flowing back into the door washing cavity 1020 and flowing out from the air inlet.

[0039] like Figures 1 to 2 As shown, the door structure includes a panel 100, a partition 200 and a bowl body 300. The partition 200 is arranged between the bowl body 300 and the panel 100, so that an electrical cavity 1010 is formed between the panel 100 and the partition 200, and a door washing cavity 1020 is formed between the partition 200 and the bowl body 300. The air duct structure 500 is arranged in the electrical cavity 1010, and the partition 200 is provided with a through hole, which is close to the bottom position of the partition 200, and the air outlet 530 of the air duct structure 500 is connected to the through hole.

[0040] Specifically, the air outlet 530 of the air duct structure 500 abuts against the partition 200 and communicates with the through hole, so that the water inside the door washing cavity 1020 can enter the interior of the air duct structure 500 but cannot enter the interior of the electrical cavity 1010; at the same time, during the drying effect, the wind inside the air duct structure 500 can enter the interior of the door washing cavity 1020.

[0041] It should be noted that the form is not limited to opening a through hole on the partition 200. The air duct structure 500 can also partially penetrate the partition 200 and extend into the interior of the door washing cavity 1020. The air outlet 530 is set on the air duct structure 500 that extends into the interior of the door washing cavity 1020. At this time, water enters the interior of the air duct structure 500 through the air outlet 530. The air duct structure 500 can separate the water from the electrical cavity 1010. The air outlet 530 is set vertically upward so that during the drying effect, the heated air flows directly upward through the air outlet 530 to perform the drying effect, thereby improving the drying efficiency.

[0042] In this embodiment, a loading port 400 is provided on the door structure, and laundry is loaded into the door washing cavity 1020 through the loading port 400. Two implementation methods are provided according to the different positions of the loading port 400, as follows.

[0043] like Figures 1 to 6 In the specific embodiment shown, the delivery port 400 is located on the panel side, and the delivery port 400 passes through the panel 100 and the partition 200 in sequence and is connected to the door washing chamber 1020.

[0044] Specifically, the delivery port 400 forms a delivery channel 410 between the panel 100 and the partition 200 to isolate the delivery port 400 from the electrical cavity 1010 . A delivery door 900 is openably and closably provided at the delivery port 400 to block or avoid the delivery port 400 .

[0045] In a specific embodiment not shown in the figures, a placement port 400 is provided on the bowl body 300 , and the placement port 400 is communicated with the door washing cavity 1020 .

[0046] Specifically, the door washing mechanism with bottom air inlet and drying further includes a delivery door 900 , which can be opened and closed at the delivery port 400 to block or avoid the delivery port 400 .

[0047] like Figure 6As shown, an air inlet 210 and an exhaust hole 230 are provided on the door structure. The air inlet 210 is provided on the partition 200, and the air inlet 210 is connected to the electrical chamber 1010. An exhaust hole 230 is also provided on the partition 200, and the exhaust hole 230 is connected to the door washing chamber 1020. The exhaust hole 230 is located above the highest water level. The highest water level is the highest position that water can reach after water flows into the door washing chamber 1020, which is the highest water level.

[0048] Inevitably, if there is a maximum water level, there must be a minimum water level. The minimum water level refers to the lowest water level height under which washing can be completed in the door washing chamber 1020. According to the type and volume of the laundry, the water level is adjusted between the maximum water level and the minimum water level to fully clean the laundry.

[0049] It should be noted that the air inlet 210 can be set on the partition 200, or on the panel 100, or on both the partition 200 and the panel 100; the exhaust hole 230 can be set on the partition 200, or on the bowl body 300, or on both the partition 200 and the bowl body 300.

[0050] Specifically, the air inlet 210 delivers air to the air duct structure 500, which then exhausts the air through the air outlet 530 into the door washing chamber 1020 for washing or drying, and then exhausts the air through the exhaust vent 230. During the drying process, the hot air discharged from the air outlet 530 of the air duct structure 500 dries the laundry and evaporates the moisture in the laundry before being exhausted through the exhaust vent 230.

[0051] like Figure 2 and Figure 5 As shown, the air outlet 530 of the air duct structure 500 includes a plurality of microporous structures arranged at intervals. The wind in the air outlet 530 passes through the plurality of microporous structures and enters the interior of the door washing cavity 1020. The plurality of microporous structures allow the wind to enter the interior of the door washing cavity 1020 evenly to improve the effect of hot bubble washing or drying.

[0052] Specifically, the plurality of microporous structures are arranged at intervals along the extension direction of the air duct structure 500 , and the extension direction of the air duct structure 500 refers to the direction in which the air duct body 520 extends from the air inlet end to a direction away from the air inlet end.

[0053] Preferably, the diameter of a single microporous structure is 3 mm to 5 mm.

[0054] It should be noted that when the multiple micropores are arranged along the extension direction of the air duct structure 500, the apertures increase sequentially to ensure that the air output of the micropores is the same.

[0055] like Figure 6As shown, the heating assembly 700 is close to the bottom of the door washing cavity 1020 relative to the top of the door washing cavity 1020 in the height direction of the door structure.

[0056] Specifically, the heating component 700 is close to the bottom of the door washing cavity 1020 so that when it is necessary to heat the water inside the door washing cavity 1020, sufficient water can be introduced into the door washing cavity 1020. At this time, the water flows back into the interior of the air duct structure 500, and the water submerges the heating component 700. When the heating component 700 is working, it can heat the water.

[0057] Furthermore, the heating assembly 700 includes a heating wire, which is coiled on the inner wall of the air duct structure 500 .

[0058] Furthermore, the heating component 700 is not limited to a heating wire and may be other structures that can achieve a heating effect, such as a heating rod.

[0059] It should be noted that since the heating component 700 has the function of heating water, when the heating component 700 is an electric temperature controller, the heating component 700 includes a heating element, a heating circuit and a temperature controller. The heating element is connected to the temperature controller through the heating circuit. The heating circuit and the temperature controller are both arranged inside the electrical cavity 1010 to avoid contact with water.

[0060] like Figures 1 to 6 As shown, the air duct structure 500 includes an air duct body 520 and a fan 510. The air duct body 520 has an air outlet 530. The heating component 700 is arranged inside the air duct body 520. The heating component 700 and the air inlet end of the air duct body 520 are spaced apart so that a waterless pipe section is formed between the heating component 700 and the air inlet end; the fan 510 is arranged at the air inlet end of the air duct body 520 and supplies air into the air duct body 520. The heating component 700 and the fan 510 are located at both ends of the waterless pipe section.

[0061] Specifically, the water inside the door washing cavity 1020 may enter the interior of the air duct structure 500 along the air outlet 530 of the air duct structure 500. Therefore, the heating component 700 is not set at the top of the air duct body 520 to prevent the heating component 700 from coming into contact with water. The heating component 700 and the air inlet end of the air duct body 520 are spaced apart, and a water-free pipe section is formed between the heating component 700 and the air inlet end of the air duct body 520. There is no water inside the water-free pipe section to prevent water from coming into contact with the fan 510 and causing a malfunction of the fan 510.

[0062] like Figures 1 to 6 As shown, the air duct body 520 extends along the circumference of the door structure to form an arc-shaped tubular structure.

[0063] Specifically, the air duct body 520 is configured as an arc-shaped tubular structure to prevent the air duct body 520 from affecting the internal space of the door structure and facilitate disassembly for maintenance and replacement.

[0064] Furthermore, the distance between the air inlet end of the air duct body 520 and the top of the door structure is smaller than the distance between the air inlet end of the air duct body 520 and the bottom of the door structure.

[0065] It should be noted that the air inlet 210 is communicated with the air inlet of the fan 510 to provide an air source for the fan 510 .

[0066] like Figures 4 and 5 As shown, the door washing mechanism with bottom air inlet drying also includes a driving member 610 and a pulsator 620. The driving member 610 is installed inside the electrical cavity 1010, and the pulsator 620 is arranged inside the door washing cavity 1020 and is located below the highest water level. The driving member 610 is driven and connected to the pulsator 620, and the driving member 610 drives the pulsator 620 to move to stir the laundry inside the door washing cavity 1020.

[0067] Specifically, it is not limited to the structure of the pulsator 620, and can also be other structures that can achieve agitation of the laundry. The driving member 610 includes a motor, and the driving member 610 can also be a rotating cylinder, etc., whichever can provide a rotational power source.

[0068] like Figure 6 As shown, the door washing mechanism with bottom air inlet and drying further includes a bracket 800 , which is disposed in the door washing cavity 1020 and above the air outlet 530 of the air duct structure 500 .

[0069] Specifically, the support 800 separates the laundry from the air outlet 530 of the air duct structure 500 to prevent the laundry from blocking the air outlet 530 . Meanwhile, the laundry on the support 800 facilitates the air duct structure 500 to dry the laundry.

[0070] like Figure 1 and Figure 4 As shown, a drain outlet 220 is further provided on the door structure, which is connected to the door washing chamber 1020 and is located below the bracket 800 .

[0071] Specifically, the bracket 800 separates the laundry from the drain outlet 220 to prevent the laundry from blocking the drain outlet 220 .

[0072] It should be noted that the drain outlet 220 is provided on the partition 200 and is located at the lowest point of the partition 200 in the vertical direction, so as to facilitate the full discharge of water inside the door washing cavity 1020 .

[0073] Inevitably, the door washing mechanism with bottom air inlet and drying also has a water inlet, which is provided on the partition 200 and communicates with the door washing cavity 1020 so that water can enter the interior of the door washing cavity 1020. A water inlet valve is provided on the water inlet to control water inlet, and a drain valve is provided on the drain port 220 to control drainage.

[0074] In this embodiment, the door washing mechanism with bottom air inlet and drying also includes a temperature control component, which senses the water temperature. The temperature control component is electrically connected to the temperature controller of the heating component 700. When the water temperature reaches the preset temperature of the temperature control component, the temperature control component controls the heating element of the heating component 700 to stop heating.

[0075] Specifically, the temperature control component includes at least one of a water temperature sensor and a temperature limiter.

[0076] It should be noted that when the temperature control switch is a water temperature sensor, its preset temperature can be adjusted; when the temperature control switch is a temperature limiter, its preset temperature can only be one temperature.

[0077] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0078] 1. The washing device includes a complete machine 1100 and a door-body washing mechanism with bottom air inlet and drying. The complete machine 1100 has an outer drum washing chamber 1110. The outer drum washing chamber 1110 and the chamber of the door-body washing mechanism with bottom air inlet and drying cooperate to form two independent chambers, both of which can be used for washing and drying. Among them, the air outlet 530 of the air duct structure 500 of the door-body washing mechanism with bottom air inlet and drying is set below the lowest water level. In this way, when there is no water in the door-body washing chamber 1020, the air in the air duct structure 500 can be heated by the heating component 700 and blown into the door-body washing chamber 1020 through the air outlet 530 through the operation of the air duct structure 500, thereby drying the laundry in the door-body washing chamber 1020. If there is no laundry in the door-body washing chamber 1020 at this time, the heated air can also dry out the moisture in the door-body washing chamber 1020, thereby preventing the growth of bacteria. When there is water in the door washing cavity 1020 and the air duct structure 500 is working, the air in the air duct structure 500 can be heated by the heating component 700 and blown into the door washing cavity 1020 through the air outlet 530, thereby performing hot bubble washing on the laundry in the door washing cavity 1020, thereby improving practicality. Of course, if there is water in the door washing cavity 1020 and the air duct structure 500 does not supply air to the door washing cavity 1020, under the action of gravity, the washing water in the door washing cavity 1020 will flow back into the air duct structure 500 through the air outlet 530 of the air duct structure 500, so that when the water level reaches a certain condition, the heating component 700 is used to heat the water, which can quickly dissolve the detergent and quickly remove stains on the clothes, thereby enhancing the washing effect and improving the washing efficiency.

[0079] 2. A bracket 800 is provided to prevent laundry from blocking the air outlet 530 and the drain outlet 220 of the air duct structure 500, thereby ensuring normal washing and drying operations.

[0080] 3. A temperature control component is provided to control the water temperature inside the door washing cavity 1020 by a preset temperature value to achieve a good washing effect and avoid damage to the laundry due to overheating.

[0081] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
