Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and more specifically, to a dishwasher with steam condensation recovery. Background Technology

[0002] During the washing process, dishwashers need to heat the water, and the inner drum of the dishwasher will generate steam. Currently, dishwashers on the market usually exhaust steam from the rear, side, or front. This can cause the customer's cabinet to be in a warm and humid environment for a long time, which may lead to corrosion. Alternatively, the high temperature steam generated from the front vent may pose a risk of burns. Directly discharged steam will also condense and accumulate quickly on the customer's countertop, forming water stains on the floor, affecting the customer experience and posing a risk of slipping. Moreover, the colder the weather, the more clearly the steam is visible, which greatly affects the user experience.

[0003] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dishwasher with steam condensation recovery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steam condensation and recovery dishwasher includes an inner tub and a door. The door is hinged to the lower edge of the opening of the inner tub. The door includes an inner door and an outer door. A recovery pipe is provided between the inner door and the outer door. The two ends of the recovery pipe are located at the upper and lower parts of the inner door, respectively, and are connected to the inner tub. Steam generated in the inner tub is transferred into the recovery pipe and dissipates heat outward through the pipe wall to form condensate. The condensate flows back into the inner tub.

[0007] Furthermore, the recovery pipe is equipped with a fan for drawing steam from the inner liner into the recovery pipe.

[0008] Furthermore, the recycling tube is installed on the inner door, and the recycling tube is a hollow tubular structure with foldable and telescopic properties.

[0009] Furthermore, the recovery pipe includes a steam inlet and a drain section for communicating with the inner liner, and a deformable section with foldable and telescopic properties. The upper part of the inner door has a steam vent hole. The steam inlet is installed at the steam vent hole and communicates with the inner liner through the steam vent hole. One end of the drain section is bent downwards toward the opening of the inner liner.

[0010] Furthermore, the inner liner has a bottom plate that extends upward toward the opening of the inner liner and forms an extension edge, with the port of the drain section located inside the extension edge.

[0011] Furthermore, a baffle is installed on the inner door at the position corresponding to the extended edge, the end of the extended edge abuts against the inner wall of the baffle, and one end of the drainage part passes through the baffle.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up a recovery pipe, the steam generated in the inner drum during the dishwasher washing process can be transferred into the recovery pipe and dissipated to the outside through the pipe wall to form condensate. The condensate flows back into the inner drum, which solves the problems of steam exhaust causing the customer's cabinet to be in a hot and humid environment for a long time and thus corroding, and the risk of burns caused by high temperature steam generated at the front steam outlet. It also solves the problems of steam exhaust causing condensation and accumulation on the customer's countertop and water stains on the floor.

[0014] 2. In this utility model, the recovery tube is a hollow tubular structure with foldable and telescopic properties. On the one hand, the recovery tube can be telescopic to meet the needs of dishwashers of different heights and sizes at the same time. On the other hand, the recovery tube can be stretched to increase the flow path of steam, improve the condensation effect, and convert as much steam as possible into condensate.

[0015] 3. In this utility model, by setting a baffle, the steam is condensed and prevented from entering the door body. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: A dishwasher with steam condensation recovery, such as Figures 1-6 As shown, it includes an inner liner 1 and a door 2. The door 2 is installed on the lower edge of the opening of the inner liner 1 by a hinge 5. The door 2 includes an inner door 201 and an outer door 202. The inner door 201 covers the opening of the inner liner 1, while the outer door 202 mainly serves to decorate and install the display panel.

[0025] Furthermore, such as Figure 2 As shown, a recovery pipe 3 is provided between the inner door 201 and the outer door 202. The two ends of the recovery pipe 3 are located at the upper and lower parts of the inner door 201, respectively, and are connected to the inner tub 1. By setting up the recovery pipe 3, the steam generated in the inner tub 1 during the dishwasher's washing process can be transferred into the recovery pipe 3 through one end. As the steam flows to the other end of the recovery pipe 3, it dissipates heat through the pipe wall, forming condensate. The condensate then flows back into the inner tub 1 through the other end of the recovery pipe 3. This method solves the problems of steam venting causing the customer's cabinet to be in a hot and humid environment for a long time, leading to corrosion, and the risk of burns from high-temperature steam generated at the front steam vent. It also solves the problems of steam condensation on the customer's countertop and water stains on the floor caused by steam venting.

[0026] Specifically, a fan 301 is installed inside the recovery pipe 3. The fan 301 is used to draw steam from the inner liner 1 into the recovery pipe 3. At the same time, under the action of the fan 301, the steam flows to the other end of the recovery pipe 3 to avoid the steam accumulating at one end of the recovery pipe 3.

[0027] The recycling tube 3 is installed on the inner door 201. The recycling tube 3 is a hollow tubular structure with foldable and telescopic properties. This design allows for the simultaneous installation of dishwashers with different heights by extending and retracting the recycling tube 3. Furthermore, as... Figure 3 As shown, the recovery pipe 3 can be stretched to increase the flow path of steam, improve the condensation effect, and convert as much steam as possible into condensate.

[0028] As a preferred option, such as Figure 2 , Figure 3 and Figure 6As shown, the recovery pipe 3 includes a steam inlet 302, a deformation section 303, and a drainage section 304. The two ends of the deformation section 303 are connected to the steam inlet 302 and the drainage section 304, respectively. Both the steam inlet 302 and the drainage section 304 are connected to the inner liner 1. The fan 301 is installed inside the steam inlet 302. The deformation section 303 adopts a corrugated structure, which gives it foldable and telescopic properties. The deformation section 303 can be a corrugated pipe.

[0029] Specifically, the upper part of the inner door 201 is provided with a steam vent 203, and the steam inlet 302 is installed in the steam vent 203 and communicates with the inner liner 1 through the steam vent 203. One end of the drain 304 is downward and bent toward the opening of the inner liner 1. The steam inlet 302 is connected to the inner liner 1 through the steam vent 203. Under the action of the fan 301, the steam generated in the inner liner 1 is transferred to the steam inlet 302. The condensate formed after the steam condenses flows back to the inner liner 1 through the drain 304. At the same time, when the steam discharge is too large, since one end of the drain 304 faces the inner liner 1, it will not directly discharge steam to the outside, avoiding the safety hazard of high temperature steam scalding customers.

[0030] It should be noted that the inner tub 1 and the lower edge of the door 2 in dishwashers currently on the market are not completely sealed; that is, there is a certain gap between the bottom plate 101 of the inner tub 1 and the lower edge of the inner door 201 of the door 2. Therefore, in this embodiment of the dishwasher, if... Figure 4 and Figure 5 As shown, the bottom plate 101 extends upward toward the opening of the inner liner 1 and forms an extension edge 102. The port of the drain section 304 is located inside the extension edge 102. By setting the extension edge 102, the condensate flowing out of the drain section 304 can flow back into the inner liner 1 under the guiding effect of the extension edge 102.

[0031] Because there may be too much high-temperature steam that cannot be completely condensed into condensate in the recovery pipe 3, this embodiment installs a baffle 4 on the inner door 201 to condense the steam and prevent it from entering the door body 2. Specifically:

[0032] like Figure 5 As shown, a baffle 4 is installed on the inner door 201 at the position corresponding to the extension edge 102. The end of the extension edge 102 abuts against the inner wall of the baffle 4, and one end of the drain part 304 passes through the baffle 4. When steam is discharged from the drain part 304 of the recovery pipe 3, it will rise. Since the extension edge 102 abuts against the baffle 4, the steam cannot be discharged and accumulates at the baffle 4. The steam contacts the baffle 4 and dissipates heat outward through the baffle 4 to form condensate. The condensate drips onto the extension edge 102 and flows back to the inner liner 1 through the extension edge 102. At the same time, since the extension edge 102 and the baffle 4 abut against each other, the condensate remaining on the inner wall of the baffle 4 will be scraped into the inner liner 1 by the extension edge 102 when the door 2 is opened.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
