[0035] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-6 A dishwasher with a dehumidification device is shown, comprising a dishwasher body 1 and a dehumidification device 2, wherein the dehumidification device 2 comprises a semi-permeable membrane moisture absorption structure 3 and a water vapor evaporation structure 4, an inner cavity is formed in the dishwasher body 1, the semi-permeable membrane moisture absorption structure 3 is arranged in the inner cavity, the water vapor evaporation structure 4 is arranged on the dishwasher body 1, a water outlet end of the semi-permeable membrane moisture absorption structure 3 is communicated with a water inlet end of the water vapor evaporation structure 4, and a water inlet end of the semi-permeable membrane moisture absorption structure 3 is communicated with a water outlet end of the water vapor evaporation structure 4.

[0038] The present invention provides a dishwasher with a dehumidification device, which absorbs moisture in the inner cavity of the dishwasher through a semipermeable membrane moisture absorption structure 3, and the mixed solution of moisture absorption solution and water absorbed by the semipermeable membrane moisture absorption structure 3 is passed into a water vapor evaporation structure 4 through the water outlet of the semipermeable membrane moisture absorption structure 3, and the water vapor evaporation structure 4 heats and evaporates the mixed solution of moisture absorption solution and water, and after the water evaporates to remove the remaining moisture absorption solution, the moisture absorption solution is transported back to the semipermeable membrane moisture absorption structure 3 through the water outlet of the water vapor evaporation structure 4. The moisture absorption solution in the semipermeable membrane moisture absorption structure 3 can be recycled, with low cost, good moisture absorption effect on the inner cavity of the dishwasher, and avoids the situation that the moisture in the inner cavity of the dishwasher is not discharged in time, resulting in moisture accumulation, bacterial growth, etc.

[0039] Preferably, the water outlet of the semipermeable membrane moisture absorption structure 3 is connected to the water inlet of the water vapor evaporation structure 4 through a first pipe 31, and the water inlet of the semipermeable membrane moisture absorption structure 3 is connected to the water outlet of the water vapor evaporation structure 4 through a second pipe 32. A water pump 311 is also provided on the first pipe 31, and when the water pump 311 is working, the water in the semipermeable membrane moisture absorption structure 3 can be pumped into the water vapor evaporation structure 4.

[0040] In this embodiment, the semipermeable membrane hygroscopic structure 3 includes a semipermeable membrane pipe 30, and a hygroscopic solution is injected into the semipermeable membrane pipe 30. The semipermeable membrane pipe 30 is a pipe made of a semipermeable membrane material. By utilizing the properties of the semipermeable membrane material, which only allows the permeation of solvents or solvents and small molecular solutes but does not allow excessive molecular solutes, the hygroscopic solution is injected into the semipermeable membrane pipe 30, and the hygroscopic solution cannot pass through the pipe wall of the semipermeable membrane pipe 30 from the inside of the semipermeable membrane pipe 30 to flow out of the semipermeable membrane pipe 30, but the water molecules outside the semipermeable membrane pipe 30 can pass through the pipe wall of the semipermeable membrane pipe 30 to enter the semipermeable membrane pipe 30.

[0041] The boiling point of the hygroscopic solution used must be much higher than that of water, so that when the water in the semipermeable membrane tube 30 is input into the water vapor evaporation structure 4, the water is evaporated while the hygroscopic solution is not evaporated when the water and the hygroscopic solution are separated by heating.

[0042] The hygroscopic solution includes a lithium bromide solution, a lithium chloride solution, or a calcium chloride solution. The boiling point of the lithium bromide solution, the lithium chloride solution, or the calcium chloride solution is much higher than the boiling point of water, that is, in the water vapor evaporation structure 4, by heating the mixed solution of the hygroscopic solution and water to a set temperature, when the boiling point of water or slightly higher than the boiling point of water is reached, water can be separated from the hygroscopic solution. In this embodiment, the set temperature is 100°-120°. The heated hygroscopic solution flows back into the semipermeable membrane hygroscopic structure 3, because the higher the temperature of the hygroscopic solution, the lower the unsaturation, and the better it can absorb water vapor.

[0043] The semipermeable membrane pipe 30 is arranged in a spiral shape, which can increase the contact area between the semipermeable membrane pipe 30 and the outside and save space.

[0044] The cross section of the semipermeable membrane pipe 30 is in the shape of a half gear. That is, the cross section of the semipermeable membrane is in the shape of a semicircle, and a fin structure is protruding on the arc of the semicircle. The end of the semipermeable membrane pipe 30 along the vertical smooth cross section is used to connect with the inner wall of the dishwasher, which is convenient for installing the semipermeable membrane pipe 30 on the inner wall of the dishwasher. The fin structure extends toward the inner cavity of the dishwasher, which can effectively increase the contact area between the semipermeable membrane pipe 30 and the inner cavity of the dishwasher.

[0045] The water vapor evaporation structure 4 includes an evaporation chamber 41 . A water inlet and a water outlet of the water vapor evaporation structure 4 are both arranged on the evaporation chamber 41 . A heating structure 411 is arranged on the evaporation chamber 41 .

[0046] The water vapor evaporation structure 4 includes a shell 42 and an evaporation plate 43, the left edge and the right edge of the evaporation plate 43 are respectively connected to the inner wall of the shell 42, the front end edge of the evaporation plate 43 extends upward to form a first baffle 431, the rear end edge of the evaporation plate 43 extends upward to form a second baffle 432, and the evaporation chamber 41 is formed between the evaporation plate 43 and the first baffle 431 and the second baffle 432.

[0047] The left edge of the evaporation tray 43 is connected to the left side wall of the shell 42, and the right edge of the evaporation tray 43 is connected to the right side wall of the shell 42. The evaporation chamber 41 is formed between the evaporation tray 43 and the first baffle 431, the second baffle 432, the left side wall of the shell 42, the right side wall of the shell 42, and the top wall of the shell 42.

[0048] The water vapor evaporation structure 4 also includes an axial flow fan 44, which is arranged at the lower end of the evaporation plate 43, and a first air inlet channel 5 is formed between the first baffle 431 of the evaporation plate 43 and the shell 42, and a second air inlet channel 6 is formed between the second baffle 432 of the evaporation plate 43 and the shell 42. The first air inlet channel 5 and the second air inlet channel 6 connect the axial flow fan 44 with the evaporation chamber 41.

[0049] The front end of the top of the shell 42 protrudes upward to form a first arch bridge portion 421, and the rear end of the top of the shell 42 protrudes upward to form a second arch bridge portion 422. The first air inlet channel 5 includes a first air guide portion 51 formed between the first baffle plate 431 and the first arch bridge portion 421, and the second air inlet channel 6 includes a second air guide portion 61 formed between the second baffle plate 432 and the second arch bridge portion 422. The cross section of the first arch bridge portion 421 or the second arch bridge portion 422 is "n" shaped. The first baffle plate 431 is below the first arch bridge portion 421, and the second baffle plate 432 is below the second arch bridge portion 422.

[0050] The first air inlet channel 5 includes a first air inlet gap 52 formed between the first baffle plate 431 and the front side wall of the shell 42, and the first air inlet gap 52 is connected to the first air guide portion 51. The second air inlet channel 6 also includes a second air inlet gap 62 formed between the second baffle plate 432 and the rear side wall of the shell 42, and the second air inlet gap 62 is connected to the second air guide portion 61.

[0051] An air inlet space is formed between the axial flow fan 44 and the evaporation plate 43. The air blown out by the axial flow fan 44 can enter the evaporation chamber 41 from the first air inlet gap 52 through the first air guide 51, or enter the evaporation chamber 41 from the second air inlet gap 62 through the second air guide 61 after passing through the air inlet space. This can accelerate the evaporation of water vapor.

[0052] The housing 42 is also provided with a steam outlet 45 , which is in communication with the evaporation chamber 41 , and the steam outlet 45 is provided with a solenoid valve 451 . The solenoid valve 451 is used to open or close the steam outlet 45 .

[0053] Preferably, a dehumidification sensor is provided in the inner cavity of the dishwasher for detecting the humidity in the inner cavity of the dishwasher.

[0054] When the dishwasher enters the drying program, the water pump 311 works, the solenoid valve 451 opens the steam outlet 45, and the water vapor in the inner cavity of the dishwasher is absorbed by the hygroscopic solution in the semipermeable membrane pipe 30. Under the action of the water pump 311, the mixture of water and hygroscopic solution enters the water vapor evaporation structure 4 through the first pipe 31. The heating structure 411 in the water vapor evaporation structure 4 evaporates the water in the mixture of water and hygroscopic solution, and the water vapor is discharged from the steam outlet 45. The hygroscopic solution flows back to the semipermeable membrane pipe 30 through the second pipe 32, thereby circulating. After the hygroscopic solution is heated and returns to the semipermeable membrane pipe 30, its temperature is higher and the unsaturation is lower, so it can better absorb water vapor. When the dehumidification sensor detects that the humidity in the inner cavity of the dishwasher is lower than the preset value, the dishwasher exits the drying program and stops the cycle.

[0055] Embodiment 2:

[0056] like Figure 7 , a control method for a dishwasher with a dehumidification device, comprising the following steps:

[0057] Step S101, controlling the water vapor evaporation structure to operate at a first preset power and the water pump to operate at a second preset power;

[0058] Step S102, detecting whether the working power of the water vapor evaporation structure changes;

[0059] If yes, go to step S103; if no, return to step S101;

[0060] Step S103, adjusting the working power of the water pump according to the changing working power of the water vapor evaporation structure.

[0061] In step S101, the water vapor evaporation structure operates at a first preset power, where the first preset power is the operating power of the heating structure in the water vapor evaporation structure.

[0062] When the water vapor evaporation structure works at the first preset power and the water pump works at the second preset power, it can be ensured that when the water pump draws the mixture of water and hygroscopic solution in the semipermeable membrane hygroscopic structure into the water vapor evaporation structure, the semipermeable membrane hygroscopic structure still has hygroscopic solution, and it can also be ensured that the mixture of water and hygroscopic solution drawn into the water vapor evaporation structure can have all or most of the water therein removed in the water vapor evaporation structure and then flow back into the semipermeable membrane hygroscopic structure.

[0063] The water pump is controlled to operate at the second preset power to avoid excessive power of the water pump, which causes the hygroscopic solution in the semipermeable membrane hygroscopic structure to be pumped into the water vapor evaporation structure before absorbing the moisture in the inner cavity of the dishwasher, resulting in poor moisture absorption effect; and to avoid excessive power of the water pump, which causes the hygroscopic solution to fully absorb the moisture in the inner cavity of the dishwasher but not yet be pumped into the water vapor evaporation structure, resulting in low moisture absorption efficiency.

[0064] The water vapor evaporation structure is controlled to operate at a first preset power to avoid the water vapor evaporation structure power being too high, resulting in the water vapor evaporation structure temperature being too high, causing waste of resources, or causing the boiling point of the hygroscopic solution to be reached, causing the hygroscopic solution to be evaporated; and to avoid the water vapor evaporation structure power being too low, resulting in the mixed liquid of water and hygroscopic solution entering the water vapor evaporation structure, and the water therein flowing back into the semipermeable membrane hygroscopic structure before being completely or mostly evaporated, resulting in poor hygroscopic effect and low hygroscopic efficiency.

[0065] The first preset power and the second preset power are preset values ​​obtained after multiple experiments before the dishwasher with a dehumidification device leaves the factory. It is a working state in which the water vapor evaporation structure and the semi-permeable membrane moisture absorption structure can cooperate well with each other, ensuring that the water vapor in the inner cavity of the dishwasher can be efficiently removed.

[0066] In step S103, the working power of the water pump is adjusted according to the changed working power of the water vapor evaporation structure to ensure the moisture absorption effect and ensure that the water vapor in the inner cavity of the dishwasher can be removed efficiently.

[0067] In step S103, the steps of adjusting the working power of the water pump according to the changed working power of the water vapor evaporation structure are specifically as follows:

[0068] When the working power of the water vapor evaporation structure increases by the first preset value, the working power of the water pump is controlled to increase by the second preset value.

[0069] Ensure the moisture absorption effect and ensure that the water vapor in the inner cavity of the dishwasher can be removed efficiently.

[0070] The first preset value is 80-110 rpm, and the second preset value is 8-12% of the second preset power. In this embodiment, the first preset value is 100 rpm, and the second preset value is 10% of the second preset power.

[0071] After step S103, the following steps are also included:

[0072] Step S104, detecting whether the humidity in the inner cavity of the dishwasher is less than a preset humidity;

[0073] If yes, go to step S105; if no, return to step S103;

[0074] Step S105, controlling the water pump to turn off.

[0075] The water vapor evaporation structure is provided with a steam outlet for discharging water vapor. After the water pump is controlled to be turned off in step S105, the steam outlet can be controlled to be closed after a preset time has passed. The preset time is 2-10 minutes. In this embodiment, the preset time is 5 minutes.

[0076] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
