Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically relating to a dishwasher that can automatically open the door to dry the washed dishes in the inner tub, particularly relating to an automatic door opening and drying control method for a dishwasher, and also relating to a dishwasher using the above-mentioned drying control method. Background Technology

[0002] With the increasing electrification of housework, my country's dishwasher market has great development potential. Dishwashers are devices that can automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks, which not only reduces the labor intensity of users but also improves the cleanliness of tableware.

[0003] In addition to washing, dishwashers also have a drying function. After the washing cycle is completed, the dishwasher continues to dry the dishes. After the washing cycle ends, the door opens automatically to allow the moisture in the inner tank to gradually escape, and the dishes are dried by the residual heat of the washing chamber. This not only dries the dishes quickly, but also does not increase power consumption at all, thus improving the drying efficiency of the dishwasher.

[0004] Most existing dishwashers have an automatic door opening function. During the drying cycle, the door opens automatically to gradually expel moisture from the inner drum. However, if the dishwasher door remains open continuously in this design, the temperature inside the drum drops rapidly. Water on the surface of the dishes doesn't evaporate quickly enough and tends to remain, resulting in poor drying. Therefore, current dishwasher drying processes suffer from a trade-off between drying efficiency and drying effectiveness.

[0005] In view of the above-mentioned technical deficiencies, this application is hereby submitted. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a drying control method for a dishwasher, so as to achieve the purpose of accelerating the drying efficiency of the dishwasher and preventing the formation of condensate in the inner tank.

[0007] To solve the aforementioned technical problem and achieve the aforementioned technical effect, the basic design concept of the technical solution adopted by the present invention is as follows: A drying control method for a dishwasher includes: controlling the dishwasher door to open and close intermittently during a drying program, and using the open door to intermittently ventilate the dishwasher drum.

[0008] Furthermore, while the dishwasher is performing the drying cycle, the following steps are performed alternately: S1. The dishwasher door is opened until the door closing conditions are met; S2. The dishwasher door closes until the conditions for opening the door are met; Repeat the dishwasher door opening step S1 and closing step S2 as described above until the conditions for ending the dishwasher drying program are met, at which point the dishwasher drying program ends.

[0009] Furthermore, the door closing conditions include the dishwasher door being open for a set duration t1n, and / or the temperature drop inside the dishwasher tub reaching a set value ΔTn1, and / or the temperature inside the dishwasher tub reaching a set value Tn1.

[0010] Furthermore, the door opening conditions include the dishwasher door closing time reaching a set duration t2n, and / or the dishwasher inner tub temperature reaching a set degree ΔTn2, and / or the dishwasher inner tub temperature reaching a set degree Tn2.

[0011] Furthermore, the drying end conditions include the dishwasher door being opened for a cumulative period of time t', and / or the internal temperature of the dishwasher tub decreasing to a set temperature T0, and / or the dishwasher door being opened a cumulative number of times N.

[0012] Furthermore, during the drying program of the dishwasher, the dishwasher door is controlled to open for a certain period of time t1n and close for a certain period of time t2n until the number of times the dishwasher door is opened reaches the set number N, at which point the drying program ends.

[0013] Furthermore, during the drying cycle of the dishwasher, the dishwasher door is controlled to open and close at varying frequencies; the varying frequencies are any or a combination of the duration t1n of each door opening and the duration t2n of each door closing.

[0014] Furthermore, the duration t1n of each door opening of the dishwasher is greater than the duration t1n-1 of the previous door opening; the duration t2n of each door closing of the dishwasher is less than the duration t2n-1 of the previous door closing.

[0015] Furthermore, during the drying cycle of the dishwasher, the dishwasher door is controlled to open and close at varying intervals with varying opening widths.

[0016] Furthermore, the opening range Hn of the dishwasher door in each iteration is greater than the opening range Hn-1 of the previous iteration; preferably, the dishwasher door is installed on the dishwasher body in an outward flip-open manner, and the opening angle An of the dishwasher door in each iteration is greater than the opening range An-1 of the previous iteration.

[0017] Furthermore, during the drying process of the dishwasher, the dishwasher door is controlled to open and close intermittently for at least one period of time; Preferably, the dishwasher door is controlled to open and close at intervals, at least during the beginning and end of the drying cycle.

[0018] Furthermore, the dishwasher's drying process is divided into multiple time periods: the first time period, the second time period, ... the nth time period... During different periods of the dishwasher's drying program, control the dishwasher to open and close the door at different intervals using different door opening modes; In each door opening mode, the opening duration Tn1, closing duration Tn2, and opening width Hn of each door opening are all the same.

[0019] Furthermore, before the dishwasher executes the drying program, it determines whether the conditions for intermittent door opening drying are met; if so, the intermittent door opening drying program is started, controlling the door to open and close intermittently; if not, the door-closed drying program or the normally open door drying program is executed.

[0020] Furthermore, before the dishwasher executes the drying program, it determines whether the ambient temperature of the dishwasher is greater than the set value; if so, it executes the normally open door drying program, controlling the door to open until the drying program ends; if not, it executes the intermittent door drying program, controlling the door to open and close intermittently.

[0021] Furthermore, during the interval door-opening drying program, the dishwasher turns on the air intake fan during the door opening period, and uses the air intake duct to draw air into the dishwasher's inner drum.

[0022] Furthermore, during the interval door-opening drying program, the temperature inside the dishwasher is detected when the door is closed; if the temperature inside the dishwasher is lower than the minimum set temperature, the gas inside the dishwasher is heated until the temperature inside the dishwasher reaches the set optimal drying temperature. Preferably, heating the inner liner includes introducing hot air into the inner liner and / or directly heating the airflow inside the inner liner.

[0023] The present invention also provides a dishwasher, comprising: a main body, an inner tub for placing tableware, and a door installed on the main body for opening and closing the inner tub; an automatic door opening mechanism installed on the main body for automatically opening or closing the door, and drying the tableware in the inner tub using any of the above-described dishwasher drying control methods.

[0024] Furthermore, a water temperature sensor is installed on the dishwasher's water inlet pipe to detect the water temperature entering the dishwasher.

[0025] Furthermore, the dishwasher itself is equipped with a temperature sensor to detect the temperature inside the dishwasher tub.

[0026] The technical solution described in this invention has the following advantages over the prior art: By employing the aforementioned control methods, the dishwasher utilizes a spaced-out door design to ventilate the inner drum, preventing the temperature inside from dropping too rapidly. This avoids issues such as condensation on the dishes, representing a significant technological advancement that allows the dishwasher to efficiently dehumidify and dry even at low temperatures. Furthermore, the driving force generated by opening and closing the door creates an airflow at the drum's opening, accelerating ventilation between the drum and the outside environment and greatly improving the dishwasher's drying efficiency.

[0027] At the same time, the method of the present invention is simple, effective, and suitable for widespread use.

[0028] To make the design concept of the technical solution of the present invention clearer and to facilitate further understanding of its beneficial effects, some specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] For example Figure 1 As shown in the illustration, this invention introduces a dishwasher, comprising: a main body 1, with an inner tub 4 inside the main body 1. The inner tub 4 is hollow, forming a cavity for placing tableware. The inner tub 4 is equipped with washing structures such as spray arms. The dishwasher is connected to a water inlet pipe. The dishwasher uses water, automatically added or manually added additives to form a washing mixture. The washing mixture is sprayed into the inner tub 4 through the washing structures such as the spray arms, thereby cleaning the tableware placed in the inner tub 4. One side of the dishwasher main body 1 has an outwardly opening door 2. The door 2 can open by flipping outwards, by pulling up and down, or by any other existing form. The door 2 is located at the opening of the dishwasher inner tub 4. When the door 2 is closed, it closes the opening of the dishwasher inner tub 4; when the door 2 is open, it opens the opening of the dishwasher inner tub. This allows the opening of the dishwasher inner tub to either form a sealed washing chamber through the opening and closing action of the door, or to be directly connected to the outside.

[0036] For ease of description in this invention, such as Figure 1As shown, the dishwasher door 2 is located on the front side of the main body 1. The door 2 is a hinged door that is connected to the main body 1 at the bottom via a horizontal rotating shaft. The front side of the dishwasher body 1 is provided with an automatic door opening mechanism 3. The automatic door opening mechanism 3 includes a locking hook that can automatically extend and retract forward. The end of the locking hook is hooked to the upper side of the door 2, so that the locking hook automatically extends outward under the drive of the motor, causing the upper end of the door 2 to flip outward and open. This causes the door 2 to flip outward at a certain angle and open a certain gap, allowing the interior of the inner tub 4 to communicate with the outside through the opening gap for ventilation and drying of the tableware in the inner tub 4.

[0037] Of course, the automatic door opening mechanism 3 in this invention can also adopt other forms in the prior art, and is not limited to the above structure. Any existing structure that can automatically control the door 2 to open or close after receiving a trigger signal can be applied to the control method described in this invention.

[0038] In this embodiment of the invention, a water temperature sensor is provided on the dishwasher's water inlet pipe to detect the water temperature entering the dishwasher; preferably, a temperature sensor is provided on the dishwasher body to detect the temperature inside the dishwasher's inner tub.

[0039] like Figures 1 to 5 As shown in the embodiment of the present invention, a drying control method applied to the above-mentioned dishwasher is introduced, including: when the dishwasher is performing a drying program, controlling the dishwasher door to open and close intermittently, and using the open door to intermittently ventilate the dishwasher inner tub.

[0040] By employing the aforementioned control methods, the dishwasher utilizes a spaced-out door design to ventilate the inner drum, preventing the temperature inside from dropping too rapidly. This avoids issues such as condensation on the dishes, representing a significant technological advancement that allows the dishwasher to efficiently dehumidify and dry even at low temperatures. Furthermore, the driving force generated by opening and closing the door creates an airflow at the drum's opening, accelerating ventilation between the drum and the outside environment and greatly improving the dishwasher's drying efficiency.

[0041] like Figure 2 As shown in this embodiment of the invention, when the dishwasher performs the intermittent door-opening drying program, the following steps are performed alternately: S1. The dishwasher door is opened until the door closing conditions are met; S2. The dishwasher door closes until the conditions for opening the door are met; Repeat the dishwasher door opening step S1 and closing step S2 as described above until the conditions for ending the dishwasher drying program are met, at which point the dishwasher drying program ends.

[0042] In this embodiment of the invention, the door closing conditions include any or a combination of the following: the dishwasher door opening time reaches a set duration t1n, and / or the temperature drop inside the dishwasher tub reaches a set degree ΔTn1, and / or the temperature inside the dishwasher tub reaches a set degree Tn1; that is, the door closing action is performed when the dishwasher door opening time reaches the set duration t1n, and / or when the temperature drop inside the dishwasher tub reaches the set degree ΔTn1, and / or when the temperature inside the dishwasher tub reaches the set degree Tn1. In this embodiment of the invention, the door closing conditions corresponding to each opening of the dishwasher door can be the same or different. For example, the door opening time reaching the set duration t1n can be set differently for each opening of the dishwasher door, the temperature drop inside the dishwasher tub reaching the set degree ΔTn1 can be set differently, and the temperature inside the dishwasher tub reaching the set degree Tn1 can be set differently, etc.

[0043] In this embodiment of the invention, the door opening conditions include any or a combination of the following: the dishwasher door closing time reaches a set duration t2n, and / or the dishwasher inner tub temperature reaches a set degree ΔTn2, and / or the dishwasher inner tub temperature reaches a set degree Tn2, etc.; that is, the door opening action is performed when the dishwasher door closing time reaches the set duration t2n, and / or when the dishwasher inner tub temperature reaches the set degree ΔTn2, and / or when the dishwasher inner tub temperature reaches the set degree Tn2. In this embodiment of the invention, the opening conditions corresponding to each closing of the dishwasher door can be the same or different. For example, the set duration t2n of the door closing time corresponding to each closing of the dishwasher can be set differently, the set degree ΔTn2 of the dishwasher inner tub temperature can be set differently for each closing of the dishwasher, and so on.

[0044] In this embodiment of the invention, the drying end condition includes any one or a combination of the following: the dishwasher door being opened for a cumulative period of time t', and / or the internal temperature of the dishwasher tub decreasing to a set temperature T0, and / or the dishwasher door being opened a cumulative number of times N. Example

[0045] like Figure 3 As shown in the figure, this embodiment introduces a method for controlling the opening and drying of a dishwasher, which includes: Step S101: The dishwasher executes the drying program; Step S102: Compare the ambient temperature T obtained by the dishwasher with the preset value in the dishwasher system; When the ambient temperature is greater than the preset value, execute step S103 and run the normally open door drying program; When the ambient temperature is lower than the preset value, execute step S104 and run the interval door opening drying program; Step S103: Run the normally open door drying program. The dishwasher door will remain open until the door is open for the set time t0. Then, proceed to step S105. Step S104: Run the interval door opening drying program. The dishwasher door will cycle through opening and closing multiple times until the dishwasher door is opened a set number N times. Then, proceed to step S105. Step S105: The dishwasher door closes and the dishwasher drying program ends.

[0046] In this embodiment, while the dishwasher is performing step S104, the following steps are performed alternately. S11. The dishwasher door opens until the door opening time reaches the set time t1n. S21. The dishwasher door closes until the door closing time reaches the set time t2n; Repeat the dishwasher door opening step S11 and closing step S21 as described above until the dishwasher door opening step S11 is executed a set number of times N. Then, execute step S105 and the dishwasher door opening and drying program ends.

[0047] In this embodiment, the set time t1n in each step S11 and the set time t2n in each step S21 of the dishwasher are set to the same or different. Preferably, the set time t1n in each step S11 of the dishwasher increases sequentially and the set time t2n in each step S21 decreases sequentially to further improve the drying efficiency of the dishwasher.

[0048] In this embodiment, the ambient temperature is the inlet water temperature detected during the washing program run before the dishwasher executes the drying program. Example

[0049] This embodiment also has the following technical features based on the above embodiments: This embodiment introduces a method for controlling the door opening and drying of a dishwasher. When the dishwasher executes an intermittent door opening and drying program, the dishwasher door is controlled to open and close at varying frequencies. The varying frequencies include any or a combination of the duration t1n of each door opening and the duration t2n of each door closing, which are different values.

[0050] Preferably, in order to further improve the drying effect and reduce the generation of condensate in the inner tank, the following settings can be made: the duration t1n of each door opening of the dishwasher is greater than the duration t1n-1 of the previous door opening; the duration t2n of each door closing of the dishwasher is less than the duration t2n-1 of the previous door closing. Example

[0051] This embodiment also has the following technical features based on the above embodiments: This embodiment introduces a method for controlling the door opening and drying of a dishwasher. When the dishwasher executes an intermittent door opening and drying program, the dishwasher door is controlled to open and close at varying intervals. These varying opening intervals refer to different values ​​in the opening distance between the dishwasher door and the dishwasher body during each door opening.

[0052] Preferably, in order to further improve the drying effect and reduce the generation of condensate in the inner tank, the following settings can be made: the opening range Hn of the dishwasher door each time is greater than the opening range Hn-1 of the previous time.

[0053] In embodiments of the present invention, such as Figure 1 As shown, taking the dishwasher with an outward-opening, flip-up door on the front as an example, the discussion will proceed. The door is located on the front of the dishwasher body, corresponding to and covering the opening of the inner tub on the front side of the body. The lower end of the door is rotatably hinged to the dishwasher body, and the upper end of the door can flip outward to open the opening of the inner tub. When the dishwasher performs the intermittent door-opening drying program, the opening angle An of the dishwasher door in each cycle is greater than the opening range An-1 of the previous cycle. Example

[0054] This embodiment also has the following technical features based on the above embodiments: like Figure 4 As shown in the figure, this embodiment introduces a method for controlling the intermittent door opening and drying of a dishwasher, which includes: The dishwasher's intermittent door-opening drying program is divided into multiple time periods, namely the first time period, the second time period, ... the nth time period...; During the first period of the dishwasher's drying program, the dishwasher is controlled to open and close the door intermittently in the first interval door opening mode; During the second period of the dishwasher's drying program, the dishwasher is controlled to open and close the door intermittently in a second interval door opening mode. … During the nth period of the dishwasher's drying program, the dishwasher is controlled to open and close the door at intervals in the nth interval opening mode. … In this embodiment, at least one of the opening duration t1n, closing duration t2n, and opening amplitude Hn of the dishwasher door in each interval opening mode is different from the corresponding items in other interval opening and closing modes. Preferably, the opening duration t1n, closing duration t2n, and opening amplitude Hn of each dishwasher door opening included in each interval opening mode are set to be the same as the corresponding items of other dishwasher door openings in this interval opening mode. Example

[0055] This embodiment also has the following technical features based on the above embodiments: This embodiment introduces a drying control method for a dishwasher. When the dishwasher is performing a drying program, an intermittent door opening mode is executed for at least one time period to control the dishwasher door to open and close intermittently, so as to achieve the effect of intermittent air exchange in the dishwasher inner tub during at least one time period.

[0056] Preferably, at least at the beginning of the drying cycle, the dishwasher operates in an intermittent door opening mode, controlling the dishwasher door to open and close intermittently to allow moisture from the washing process to be quickly expelled. Simultaneously, to ensure that no moisture remains in the dishwasher drum at the end of the drying cycle, the dishwasher operates in an intermittent door opening mode, controlling the dishwasher door to open and close intermittently to allow all moisture from the dishwasher to be expelled.

[0057] In this embodiment, during other periods of the dishwasher's drying program, the door can be controlled to be either normally closed or normally open. Example

[0058] This embodiment also has the following technical features based on the above embodiments: like Figure 5 As shown in the figure, this embodiment introduces a drying control method for a dishwasher, which includes determining whether the conditions for intermittent door opening drying are met before the dishwasher executes the drying program; if so, the intermittent door opening drying program is started, and the door is controlled to open and close intermittently; if not, the door-closed drying program or the normally open door drying program is executed.

[0059] In this embodiment, the intermittent door-opening drying conditions include any or a combination of the following: whether the dishwasher ambient temperature is lower than the minimum set temperature, whether the dishwasher inner tub temperature is higher than the maximum set temperature, and whether there are any obstacles outside the dishwasher door. That is, when any or a combination of, or all of, the conditions such as the dishwasher ambient temperature being higher than the minimum set temperature, the dishwasher inner tub temperature being higher than the maximum set temperature, and the absence of obstacles outside the dishwasher are met, the dishwasher will start executing the intermittent door-opening drying program.

[0060] In this embodiment, after the dishwasher completes the washing program, it is determined whether to execute the intermittent door-opening drying program; if yes, it is determined whether the intermittent door-opening drying conditions are met; if yes, the dishwasher intermittent door-opening drying program is executed; if no, the dishwasher regular drying program is executed. The regular drying program can be a door-closed drying program or a door-open drying program.

[0061] In this embodiment, determining whether to execute the intermittent door-opening drying program includes using information selected by the user on the dishwasher and / or a determination result automatically generated by the dishwasher based on detection parameters.

[0062] For example: The dishwasher determines whether to perform the intermittent door-opening drying program based on the operating mode selected by the user; that is, the user pre-selects whether to perform the intermittent door-opening drying program on the dishwasher.

[0063] For example: The dishwasher obtains the ambient temperature and the internal temperature of the inner drum. When the ambient temperature is higher than the minimum set temperature and the internal temperature of the inner drum is lower than the maximum set temperature, it determines to execute the intermittent door opening drying program.

[0064] Of course, in this embodiment of the invention, the method for determining whether to execute the intermittent door-opening drying program is not limited to the above-described scheme, and any other method can be used: for example, the dishwasher obtains the ambient temperature and the internal temperature of the inner drum, and determines to execute the intermittent door-opening drying program when the difference between the ambient temperature and the internal temperature of the inner drum is less than a preset difference, etc. Furthermore, in this embodiment of the invention, the above determination methods can be combined to allow the determination method to be either manually selected by the user or automatically determined by the dishwasher.

[0065] In this embodiment of the invention, when the dishwasher determines that it will not execute the intermittent door-opening drying program, the dishwasher executes a conventional drying program with the door always closed and not automatically opened. Example

[0066] This embodiment, based on the above embodiments, also has the following technical features: In this embodiment, the dishwasher body is provided with an air inlet duct, with its two ends connected to the dishwasher inner tub and the outside of the dishwasher, respectively. An air inlet fan is installed inside the air inlet duct to draw air into the dishwasher inner tub when the air inlet fan is turned on. During the interval door-opening drying program, when the door is open, the air inlet fan is turned on to draw air into the dishwasher inner tub through the air inlet duct, accelerating the airflow in the dishwasher inner tub to flow outward from the opened door.

[0067] In this embodiment, the dishwasher is also equipped with a heating structure for heating the gas inside the dishwasher tub. This heating structure can be a heater installed in the air inlet duct to heat the incoming airflow into the tub, or a heater directly installed in the tub to heat the gas inside, etc. During the intermittent door-opening drying program, the temperature inside the dishwasher tub is monitored during the door-closing period. When the temperature inside the tub is lower than the minimum set temperature, the heating structure is activated to heat the inside of the tub until the temperature reaches the set optimal drying temperature.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
