Abstract
Description
Technical Field
[0001] The present application relates to the field of household appliance technology, and in particular to a dishwasher inner tank and a dishwasher. Background Art
[0002] Household dishwashers have greatly improved people's quality of life and effectively reduced housework time. In addition to the cleaning function, household dishwashers also have a drying function. The drying function of household dishwashers can effectively prevent dishes from dripping and getting moldy, and increase the cleanliness and convenience of household dishes.
[0003] The drying methods of household dishwashers can be mainly divided into residual temperature drying, heat exchange drying, hot air drying, automatic door drying and zeolite drying. Residual temperature drying uses the residual temperature after high-temperature washing to dry dishes; heat exchange drying adds a condensing device on the basis of residual temperature drying, which is equivalent to increasing the temperature difference. The dishes can be dried well, but there will be water vapor on the inner wall, and the dishes cannot be stored for a long time; hot air drying is similar to the principle of a hair dryer, blowing hot air into the cavity to take away the water vapor, which has a good effect, but a little more noise and consumes more electricity; automatic door drying, after washing is completed, the residual temperature is used for drying first. When the cavity reaches a certain temperature, a gap is automatically opened to take away the water vapor by the temperature difference between the inside and the outside. The effect is good and energy-saving, but it is not suitable for humid areas. In addition to considering the function, cleaning and drying effect, daily energy consumption is also a key consideration for consumers when purchasing household dishwashers.
[0004] In order to reduce water stains on dishes after washing and lower the drying cost of the dishwasher, we propose a dishwasher liner and a dishwasher. Utility Model Content

[0008] By adopting the above technical solution, the inner tank of the dishwasher cleans the dishes with hot water. After the cleaning is completed, the inner tank of the dishwasher still has a relatively high residual temperature. At this time, the heating element not only heats the inner tank body, but also heats the cavity between the inner tank body and the heat insulation cover, so that the cavity forms a relatively high temperature insulation layer, so that the residual temperature in the inner tank body will not be lost. At this time, the dishes inside the dishwasher can be residual temperature dried by the residual temperature after washing and the temperature of the heating element. The insulation layer formed by the heating element effectively prolongs the residual temperature drying time of the dishes, so that after the residual temperature drying is completed, the water stains on the dishes are effectively reduced, and the residual temperature of the inner tank body is effectively preserved by cavity heating, which effectively saves energy, reduces water stains on the dishes after washing, and reduces the drying cost of the dishwasher.

[0014] A dishwasher comprises the dishwasher inner container and outer container as described in any one of the above, wherein the dishwasher inner container is connected to the outer container so that the dishwasher inner container is located inside the outer container.
[0015] By adopting the above technical solution, the dishwasher can insulate the residual temperature of the inner tank body through the heat insulation cover and the cavity, so that the dishwasher can use the residual temperature of the inner tank body after washing to dry the dishes for a long time, effectively ensuring that there are minimal water stains on the dishes, and the energy consumed by heating the cavity through the heating element is less than the free gradient loss of heat from the inner tank body.
[0016] Preferably, a second cavity is provided between the inner container of the dishwasher and the outer shell.
[0017] Preferably, the housing comprises a dishwashing door, and the dishwashing door is provided with an automatic door opening mechanism.
[0018] Preferably, the dishwasher further comprises an external water pipe portion, wherein the external water pipe portion is located between the inner tank body and the heat insulation cover.
[0019] Preferably, the outer water pipe portion may be square or rectangular.
[0020] In summary, the present application includes at least one of the following beneficial technical effects:
[0021] 1. The dishwasher uses hot water to clean the dishes. After cleaning, the dishwasher still has a relatively high residual temperature. At this time, the heating element heats the cavity between the inner tank body and the heat insulation cover, so that the cavity forms a relatively high temperature insulation layer, so that the residual temperature in the inner tank body will not be lost. At this time, the dishes in the dishwasher can be dried with the residual temperature after washing. The insulation layer formed by the heating element effectively prolongs the residual temperature drying time of the dishes, effectively reduces the water stains on the dishes, and effectively preserves the residual temperature of the inner tank body through cavity heating, which effectively saves energy, reduces the water stains on the dishes after washing, and reduces the drying cost of the dishwasher;

[0030] The following is combined with Figure 1-6 This application is described in further detail.
[0031] Example 1
[0032] The embodiment of the present application discloses a dishwasher inner tank.
[0033] Reference Figure 1 , Figure 2 and Figure 3 , including an inner liner body 1 and a heat insulation cover 2, the heat insulation cover 2 includes a first heat insulation cover and a second heat insulation cover, the first heat insulation cover is sleeved on the inner liner body 1, and the second heat insulation cover is clamped on the first heat insulation cover, the first heat insulation cover and the second heat insulation cover jointly cover the inner liner body 1, so that the inner liner body 1 is surrounded by the heat insulation cover 2, thereby ensuring that the temperature of the inner liner body 1 is effectively kept warm, and a cavity 3 is provided between the heat insulation cover 2 and the inner liner body 1, and the cavity 3 is filled with air, so that the inner liner body 1 is not only insulated and heat-insulated by the heat insulation cover 2, but also kept warm by the cavity 3 between the heat insulation cover 2 and the inner liner body 1.
[0034] refer to Figure 4 The lower part of the outer wall of the inner tank body 1 is screwed with a heating element 4, and the heating element 4 is in a strip shape. The strip-shaped heating element 4 is arranged in close contact with the inner tank body 1, so that the inner tank body 1 is heated and the cavity 3 is heated by the heating belt. The heated cavity 3 effectively prevents the heat loss in the inner tank body 1, and due to the principle that hot air floats and cold air sinks, by installing the heating element 4 at the lower part of the inner tank body 1, it is convenient to make the heated hot air float, thereby effectively increasing the rate at which the hot air spreads throughout the cavity 3, and increasing the reaction rate of the heating cavity 3 to keep warm.
[0035] The inner tank body 1 includes a cleaning cavity for placing and cleaning dishes. The dishwasher inner tank 5 cleans the dishes with hot water. After cleaning, the dishwasher inner tank 5 still has a relatively high residual temperature. At this time, the heating element 4 heats the inner tank body 1 and the cavity 3, so that the inner tank body 1 maintains the temperature for drying the dishes, and the cavity 3 forms a relatively high temperature insulation layer, so that the residual temperature in the inner tank body 1 will not be lost. At this time, the dishes inside the dishwasher can be dried with the residual temperature after washing. The heating of the inner tank body 1 by the heating element 4 and the insulation layer formed by the cavity 3 effectively extend the residual temperature drying time of the dishes, and the water stains on the dishes are effectively reduced. The residual temperature of the inner tank body is effectively preserved by heating the cavity 3, and there is no need to add an additional drying mechanism, which effectively saves drying costs.
[0036] Furthermore, in this embodiment, the heating element 4 can also be installed on the heat insulation cover 2, and the heating element 4 can also be arranged between the heat insulation cover 2 and the inner tank body 1, as long as the inner tank body 1 and the air in the cavity 3 can be heated.
[0037] Furthermore, in this embodiment, the heating element 4 can also be a dispersed spiral tube or sheet. The heating element 4 is arranged in close contact with the inner tank body 1. The heating element 4 can also be evenly distributed on the inner tank body 1. It is only necessary for the heating element 4 to evenly heat the cavity 3.
[0038] Furthermore, in this embodiment, the heating element 4 can also be arranged in the middle and lower parts of the cavity 3, which are conducive to the rapid flow of heated air, effectively increasing the rate at which hot air spreads throughout the cavity 3, and increasing the reaction rate of heating and keeping the cavity 3 warm.
[0039] Further, in this embodiment, reference Figure 5 and Figure 6 The heating element 4 protrudes outward, so that the heating element 4 has a larger heat dissipation area, thereby enabling the heating element 4 to quickly heat the air in the cavity 3.
[0040] Furthermore, in this embodiment, a drying mechanism may be provided on the inner tank body 1, so that after the dishes in the inner tank body 1 are washed at high temperature, the dishes also undergo a special drying process, and the drying process may be heat exchange drying, hot air drying, or zeolite drying. At this time, the heating element 4 serves as an insulation process to assist the drying process.
[0041] Example 2
[0042] The embodiment of the present application discloses a dishwasher.
[0043] refer to Figure 1 , Figure 2 and Figure 3 , including the above-mentioned dishwasher liner 5 and shell 6, the dishwasher liner 5 includes an inner liner body 1 and a heat insulation cover 2, the heat insulation cover 2 is sleeved on the inner liner body 1, and a cavity 3 is provided between the heat insulation cover 2 and the inner liner body 1, and a heating element 4 is screwed in the cavity 3, so that the heating element 4 heats the air in the cavity 3 to form a high-temperature insulation layer, the shell 6 is sleeved on the heat insulation cover 2, and a second cavity 7 is provided between the shell 6 and the heat insulation cover 2. The dishwasher insulates the residual temperature of the inner liner body through the heat insulation cover 2 and the cavity 3, so that the dishwasher can dry the dishes for a long time with the residual temperature of the inner liner body 1 after washing, effectively ensuring that there are minimal water stains on the dishes, and the energy consumption of heating the cavity 3 by the heating element 4 is less than the free loss of heat of the inner liner body, and the second cavity 7 further reduces the heat loss of the inner liner body through air insulation, effectively saving energy.
[0044] The inner tank 5 of the dishwasher has a cleaning cavity, which is used to place and clean dishes. The dishwasher also includes a water tank, a water tank heating mechanism, a water pipe and a spray arm. The water tank is arranged at the lower part of the dishwasher, and the water tank heating mechanism is arranged on the water tank. The water tank heating mechanism maintains the water to be cleaned in the water tank at a certain temperature. Under normal circumstances, the washing temperature of the dishwasher is 70℃-90℃, and the cleaning temperature is 55℃-65℃. The spray arm is arranged in the cleaning cavity, one end of the water pipe is connected to the water tank, and the other end is connected to the spray arm, so that the spray arm draws water in the water tank to clean the dishes in the cleaning cavity.
[0045] refer to Figure 4The spray arm includes an upper spray arm, a middle spray arm and a lower spray arm.

The outer water pipe part 9 is rectangular / square, so that the outer water pipe part 9 fits the inner tank body 1. Since the inner tank body 1 is hot, the heating element 4 heats the inner tank body 1 and the cavity 3. Therefore, the outer water pipe part 9 is arranged on the outer wall of the inner tank body 1 to minimize the heat loss of water in the outer water pipe part 9 and effectively keep warm.
[0046] Furthermore, in this embodiment, the shell also includes a dishwashing door 8, which is rotatably connected to the cleaning chamber, so that the user can open or close the cleaning chamber by rotating the dishwashing door 8. The dishwashing door 8 can also be provided with a door opening mechanism, so that the dishwashing door 8 automatically opens after the dishes have gone through the drying process, allowing the cleaning chamber to exchange air with the outside world and quickly taking away the air containing water vapor in the cleaning chamber.
[0047] Furthermore, in this embodiment, the outer water pipe portion 9 may also be flat, as long as the heat loss of the outer water pipe portion 9 is reduced.
