Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a dishwasher. Background Technology

[0002] Dishwashers, as devices that automatically clean dishes, are attracting increasing attention. To meet the needs of different users, multi-cavity dishwashers have emerged on the market. These dishwashers achieve functional breakthroughs compared to traditional single-cavity dishwashers by introducing a multi-cavity structural design. They divide the inner drum into multiple independent chambers, each of which can operate independently, thus adapting to diverse washing scenarios.

[0003] While the multi-chamber design expands the functional boundaries of dishwashers, transforming them from simple dishwashing tools into multifunctional kitchen appliances, it also leads to higher water consumption and reduces the user experience. Utility Model Content

[0004] In view of this, the present invention provides a dishwasher to solve the problem that multi-cavity dishwashers consume a lot of water and reduce the user experience.

[0005] In a first aspect, this utility model provides a dishwasher, comprising:

[0006] Multiple working chambers, each of which is provided with a steam outlet and a water return outlet;

[0007] A condensation recovery device is connected to the steam outlet to condense the hot steam in the working chamber into condensate.

[0008] A reflux device is provided, wherein the condensate recovery device is connected to the return water port to guide the condensate to the working chamber for reuse.

[0009] Beneficial effects: Each working chamber is equipped with a steam outlet and a water return outlet. The hot steam generated during the drying process in the working chamber can enter the condensation recovery device through the steam outlet and condense into condensate in the condensation recovery device. This condensate can be used in the washing process of the dishwasher, reducing the amount of water supplied from the outside and reducing water consumption. Moreover, due to the reduction in water demand, the water inlet time is also shortened, improving cleaning efficiency. In addition, the shortened working time of the water inlet solenoid valve can also reduce energy consumption and improve the user experience.

[0010] In one optional embodiment, the condensation recovery device includes:

[0011] A condensation structure serves as the condensation matrix for the hot steam;

[0012] A condensation storage chamber is used to collect condensate formed at the condensation structure; the condensation storage chamber is connected to the return water port through the reflux device.

[0013] Beneficial effects: Hot steam forms condensate at the condensing structure, which is then collected and stored in the condensation storage chamber for easy recycling and reuse as washing water.

[0014] In one optional embodiment, the condensation structure includes:

[0015] The conveying channel has a condensation inlet and a condensation outlet, wherein the condensation inlet is connected to the steam outlet and the condensation outlet is connected to the condensation storage chamber.

[0016] Beneficial effects: Using the conveying channel for transporting hot steam as the condensing substrate results in a simple structure and allows for simultaneous transport and condensation, improving condensation efficiency.

[0017] In one optional embodiment, the condensation recovery device further includes:

[0018] A pneumatic conveyor is installed at the steam outlet to provide the driving force for steam flow.

[0019] Beneficial effects: Compared with the diffusion and circulation method that relies on the steam's own fluidity and density difference, adding wind-powered conveying components can increase the speed of hot steam transportation.

[0020] In one optional embodiment, the bottom surface of the condensation storage chamber is provided with an overflow hole, and a first control valve is provided at the overflow hole.

[0021] Beneficial effects: When there is no working chamber and water is needed, if the condensate level in the condensate storage chamber reaches the water level threshold, or if the condensate is left for too long and may cause bacteria growth and odor, the condensate can be drained through the overflow hole to ensure safety and hygiene.

[0022] In one optional implementation, the dishwasher further includes:

[0023] The condensate storage chamber is connected to the drainage mechanism via a pipeline.

[0024] Beneficial effects: The drainage mechanism can automatically control the discharge of condensate from the condensate storage chamber based on the condensate level or storage time in intelligent control mode, further improving user satisfaction.

[0025] In one alternative embodiment, the plurality of working chambers include a first cleaning chamber and a second cleaning chamber arranged in a stacked manner;

[0026] The condensation recovery device includes a condensation storage chamber and a vertically arranged conveying channel. The condensation inlet of the conveying channel is connected to the steam outlet of the first cleaning chamber and the second cleaning chamber, respectively; the condensation outlet of the conveying channel is connected to the condensation storage chamber.

[0027] Beneficial effects: When two cleaning chambers are set up, hot steam is transported along the vertically set conveying channel and condenses on the inner wall of the conveying channel. The condensate formed can flow directly downward to the condensate storage chamber by gravity, without the need to set up a water pump.

[0028] In one alternative embodiment, a water level sensor is provided inside the condensation storage chamber.

[0029] Beneficial effects: By monitoring the condensate level in the condensate storage chamber in real time, the points where water needs to be taken out and water needs to be drained can be determined in a timely and accurate manner, thereby facilitating automated control.

[0030] In one optional implementation, the reflux device includes:

[0031] The return pipe is connected at both ends to the condensation recovery device and the working chamber, respectively.

[0032] A pumping device is used to provide the driving force for the return of condensate; or, a second control valve is used to recover condensate by gravity.

[0033] Beneficial effects: When the condensate storage chamber is located above the working chamber that requires water, the second control valve of the reflux device can be opened directly, and the condensate can be recycled back to the working chamber by gravity for use; when the condensate storage chamber is located at a lower position, the condensate can be pumped to the working chamber by the pumping device for washing and other processes.

[0034] In one alternative embodiment, the steam outlet is located at the upper part of the working chamber.

[0035] Beneficial effects: Hot steam is relatively light and will concentrate in the upper part of the working chamber. By placing the steam outlet in the upper part of the working chamber, it is easier for the hot steam to flow more quickly from the steam outlet to the condensation and recovery device.

[0053] In view of this, the present utility model is proposed.

[0054] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0055] According to embodiments of the present invention, on the one hand, such as Figure 1 and Figure 2 As shown, a dishwasher is provided, comprising:

[0056] Multiple working chambers, each of which is provided with a steam outlet 1 and a water return port;

[0057] A condensation recovery device is connected to the steam outlet 1 to condense the hot steam in the working chamber into condensate.

[0058] A reflux device is provided, wherein the condensate recovery device is connected to the return water port to guide the condensate to the working chamber for reuse.

[0059] Each working chamber is equipped with a steam outlet 1 and a water return outlet. The hot steam generated during the drying process in the working chamber can enter the condensation recovery device through the steam outlet 1 and condense into condensate in the condensation recovery device. This condensate can be used in the washing process of the dishwasher, reducing the amount of water supplied from the outside and reducing water consumption. Moreover, due to the reduction in water demand, the water inlet time is also shortened, improving cleaning efficiency. In addition, the shortened working time of the water inlet solenoid valve can also reduce energy consumption and improve the user experience.

[0060] In some embodiments, the condensation recovery device includes:

[0061] A condensation structure serves as the condensation matrix for the hot steam;

[0062] The condensation storage chamber 3 is used to collect the condensate formed at the condensation structure; the condensation storage chamber 3 is connected to the return water port through the reflux device.

[0063] Hot steam forms condensate at the condensing structure, which is then collected and stored in the condensation storage chamber 3 for easy recycling and reuse as washing water.

[0064] In some embodiments, the condensation structure includes:

[0065] The conveying channel 2 has a condensation inlet and a condensation outlet. The condensation inlet is connected to the steam outlet 1, and the condensation outlet is connected to the condensation storage chamber 3.

[0066] Using the conveying channel 2 for transporting hot steam as the condensing substrate results in a simple structure and allows for simultaneous transport and condensation, thus improving condensation efficiency.

[0067] In some embodiments, the condensation recovery device further includes:

[0068] A wind-powered conveyor is installed at the steam outlet 1 to provide the driving force for steam flow.

[0069] Compared to the diffusion and circulation method that relies on the steam's own fluidity and density difference, adding wind-powered conveying components can increase the speed of hot steam transport.

[0070] In some embodiments, the bottom surface of the condensation storage chamber 3 is provided with an overflow hole 4, and a first control valve is provided at the overflow hole 4.

[0071] When no working chamber is in operation and water is needed, if the condensate level in the condensate storage chamber 3 reaches the water level threshold, or if the condensate has been left for too long and may cause bacteria growth and odor, the condensate can be drained through the overflow hole 4 to ensure safety and hygiene.

[0072] In some embodiments, the dishwasher further includes:

[0073] The condensate storage chamber 3 is connected to the drainage mechanism via a pipeline.

[0074] The system is equipped with a drainage mechanism that can automatically control the discharge of condensate from the condensate storage chamber 3 based on the condensate level or storage time in intelligent control mode, further improving user satisfaction.

[0075] In some embodiments, the plurality of working chambers include a first cleaning chamber 100 and a second cleaning chamber 200 arranged in a stacked manner;

[0076] The condensation recovery device includes a condensation storage chamber 3 and a vertically arranged conveying channel 2. The condensation inlet of the conveying channel 2 is connected to the steam outlet 1 of the first cleaning chamber 100 and the second cleaning chamber 200, respectively; the condensation outlet of the conveying channel 2 is connected to the condensation storage chamber 3.

[0077] When two cleaning chambers are set up, hot steam is transported along the vertically set conveying channel 2 and condenses on the inner wall of the conveying channel 2. The condensate formed can flow directly downward to the condensate storage chamber 3 by gravity, without the need to set up a water pump.

[0078] In some embodiments, a water level sensor is provided inside the condensation storage chamber 3.

[0079] By monitoring the condensate level in the condensate storage chamber 3 in real time, the points where water needs to be taken out and water needs to be drained can be determined in a timely and accurate manner, thus facilitating automated control.

[0080] In some embodiments, the recirculation device includes:

[0081] The return pipe is connected at both ends to the condensation recovery device and the working chamber, respectively.

[0082] A pumping device is used to provide the driving force for the return of condensate; or, a second control valve is used to recover condensate by gravity.

[0083] When the condensate storage chamber 3 is located above the working chamber that requires water, the second control valve of the reflux device can be opened directly, and the condensate can be recycled back to the working chamber for use by gravity. When the condensate storage chamber 3 is located at a low position, the condensate can be pumped to the working chamber for washing and other processes by the pumping device.

[0084] After the first cleaning chamber 100 completes the cleaning and enters the drying stage, the hot steam in the inner tank is discharged by the fan, which acts as a wind-powered conveyor. When this hot steam comes into contact with the cooler pipe wall of the conveying channel 2, it will condense. The resulting condensate will flow into the pre-designed condensate storage chamber 3 of the second cleaning chamber 200 and be used in the washing process of the second cleaning chamber 200.

[0085] The condensate storage compartment 3, which serves as the collection area, is equipped with a water level sensor, and the dishwasher door has a controllable overflow hole 4 at the bottom. When the second washing chamber 200 has not been used for an extended period, once the condensate in the condensate storage compartment 3 reaches a certain level, the dishwasher will display a prompt message reminding the user to drain the condensate, preventing bacterial growth or unpleasant odors caused by prolonged accumulation. The drained condensate can be used for other purposes.

[0086] In some embodiments, the steam outlet 1 is located at the upper part of the working chamber.

[0087] Since hot steam is relatively light, it will concentrate in the upper part of the working chamber. By placing the steam outlet in the upper part of the working chamber, it is easier for the hot steam to flow more quickly from steam outlet 1 to the condensation and recovery device.

[0088] like Figure 3 As shown, the control method for a dishwasher according to this utility model includes:

[0089] Obtain the water level of the condensate in the condensate storage chamber 3 and determine whether it has reached the preset water level;

[0090] When the condensate water level reaches the preset level, the pumping device is started or the solenoid valve is opened to recycle the condensate water.

[0091] The preset water level is the water level corresponding to the usable value. When the water level of the condensate in the condensate storage chamber 3 reaches the preset water level, it indicates that there is already a relatively large amount of water available, which can provide a considerable amount of water. When the water level is low, there is too little water available, and it is necessary to wait until the water level reaches the preset water level before taking water, so as to effectively reduce the amount of water required.

[0092] Specifically, such as Figure 4 As shown, the control method includes:

[0093] Obtain the water level of the condensate in the condensate storage chamber 3 and determine whether it has reached the water level threshold.

[0094] When the condensate water level reaches the threshold, the user is prompted to drain the condensate water or use the condensate water.

[0095] The water level threshold is the water level value corresponding to the maximum volume of the condensate storage chamber 3. When the condensate water level reaches the water level threshold, it indicates that if more condensate water is introduced, it will overflow. It is necessary to remind the user in time to drain the condensate water or remind the user to use the condensate water to avoid the situation where the condensate water overflows and causes inconvenience to the user.

[0096] Furthermore, the control method further includes:

[0097] If the condensate water level does not reach the water level threshold, the duration of unused condensate water is obtained to determine whether the preset time has been reached.

[0098] When the condensate water has not been used for a preset period of time, the user will be reminded to drain the condensate water.

[0099] To prevent the condensate in the condensate storage chamber 3 from breeding bacteria or deteriorating and producing odors if it is not used for a long time, the condensate in the condensate storage chamber 3 should be drained in time if the water level in the condensate storage chamber 3 has not reached the preset value and the time without using the condensate has reached the preset time, so as to ensure the hygiene and safety of the dishwasher's working chamber.

[0100] Multi-cavity dishwashers incorporate condensate collection and treatment. Water enters the water cup via an external water source, is drawn from the cup by a washing pump, and then sprayed onto the dishes using various spray arms. During the drying stage, the dishwasher uses air intake and exhaust systems to quickly dry the dishes. Because of the increased number of cavities, multi-cavity dishwashers generate more condensate, making condensate recycling essential.

[0101] The following explanation uses a two-chamber dishwasher as an example. During the use of the first cleaning chamber 100 and the second cleaning chamber 200, the condensate generated during the drying stage flows through the delivery channel 2 to the condensate storage chamber 3, which contains a solenoid valve and a flow meter. The solenoid valve controls the pipe connected to the water cup in the second cleaning chamber 200. When the second cleaning chamber 200 is started, the water level in the condensate storage chamber 3 is detected. When the stored water level reaches the usable value, the solenoid valve opens, and the condensate in the condensate storage chamber 3 flows to the water cup in the second cleaning chamber 200. The flow meter records the water volume for subsequent washing processes. Figure 6 As shown, when the condensate in the condensate storage chamber 3 reaches the peak water volume (water level threshold), the display area prompts the user to "drain the condensate" or reminds the user to "use the second cleaning chamber 200 for washing". When the condensate in the condensate storage chamber 3 does not reach the peak water volume, the continuous unused time of the second cleaning chamber 200 is detected. If the continuous unused time is too long, the user is reminded to drain the condensate in time to avoid the problem of condensate from being left for too long and producing odor when the condensate in the condensate storage chamber 3 does not reach the peak water volume and has not been used for a long time. The drained condensate can be used in other water use scenarios for the user.

[0102] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
