[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0037] In an increasingly competitive dishwasher industry, sales staff in shopping malls often use ordinary dishwashers to demonstrate their functions, but this fails to show the internal operating logic or visualize the washing results. Furthermore, due to limitations in water supply and drainage in shopping malls, ordinary dishwashers cannot enter the washing stage without a water supply.
[0038] Existing technology provides a dishwasher with a transparent side door, allowing users to observe the rinsing process in the dish rack. However, due to limitations in the water supply and drainage conditions of shopping malls, additional pipes and equipment are needed to meet the water supply and drainage requirements of the dishwasher, which leads to increased advertising costs.
[0039] This utility model mainly introduces a dishwasher for demonstration purposes. The door is made into a transparent structure, allowing consumers to view it directly from the outside. Only the electrical components that provide the user's direct experience of the functionality are retained; other non-displayed parts can be omitted, eliminating the need for circuit control and reducing costs. By connecting the water tray at the bottom of the washing chamber to the rinsing device, the water in the dishwasher can be continuously recycled, avoiding the need for additional piping and equipment due to water restrictions in shopping malls. This effectively reduces the display costs of the dishwasher in shopping malls.
[0040] The dishwasher of this utility model will be described below through specific embodiments.
[0041] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a dishwasher according to an exemplary embodiment of the present invention. See also: Figure 1 The dishwasher includes: a housing 1 and a door 2 movably connected to the housing 1; the door 2 is made of transparent material; the housing 1 includes an inner shell and an outer shell, and the outer shell has an operation button 3 on one side of the door 2, located below the door 2; the inner shell and the door 2 form the washing cavity of the dishwasher; a water tray is provided at the bottom of the washing cavity, and the water tray is connected to the rinsing device.
[0042] It should be noted that the technical solution provided in this embodiment is applicable to scenarios including but not limited to dishwashers in specific practices.
[0043] Specifically, the rinsing device is the same as that in a regular dishwasher, used for rinsing actions in the dishwasher, and will not be described in detail here; the dishwasher in this embodiment is equipped with a water inlet. After manually adding water once through the water inlet, the dishwasher function can be executed multiple times until the water level is low or the dishwasher is removed and then re-installed, at which point manual water addition is required again.
[0044] It is understandable that the dishwasher provided in this embodiment uses a transparent door material, which makes it easy for consumers to view directly from the outside; the water in the dishwasher can be continuously recycled by connecting the water tray at the bottom of the washing cavity to the rinsing device, which avoids the need for additional pipes and equipment due to water restrictions in shopping malls, and can effectively reduce the display cost of the dishwasher in shopping malls.
[0045] In one embodiment, see Figure 2 , Figure 2 This is a schematic diagram of the water receiving tray shown in an exemplary embodiment of the present invention. See also: Figure 2 The water receiving tray includes: a water inlet 4 and a water storage tank 5; the water inlet 4 is connected to the washing inner cavity; the water storage tank 5 is provided with a drain outlet 6, a drain pump bearing port 7 and a circulating water outlet 8; the circulating water outlet 8 is connected to the rinsing device; the drain outlet 6 is provided with a sealing cover; the drain pump bearing port 7 is provided with an end cover 9.
[0046] It should be noted that the water inlet 4 is used to receive the washing water in the washing chamber and let it flow to the water storage tank 5 for temporary storage; the reserved drain outlet 6 is used to drain the water in the dishwasher when the entire marketing process is over and the display is dismantled. During the mall marketing process, both the drain outlet 6 and the drain pump bearing port 7 need to be kept sealed. In malls with water supply and drainage conditions, water can be supplied through the reserved water inlet, and then the drain pump can be installed in the reserved drain pump bearing port 7. The drain outlet 6 can be opened to drain water normally to complete a more complete display process.
[0047] It is understood that the dishwasher provided in this embodiment is connected to the rinsing device through a circulating water outlet, so that the water in the water tank can be continuously circulated by the rinsing device without the need for water inlet and outlet, effectively avoiding the water usage restrictions of shopping malls and effectively reducing the display cost of dishwashers in shopping malls.
[0048] In one embodiment, see Figure 2 The water storage tank 5 includes a water collection part 501 and a water storage part 502 that are connected to each other; the water collection part 501 has a funnel structure and the bottom of the water collection part 501 is connected to the water storage part 502; the drain outlet 6, the drain pump bearing outlet 7 and the circulating water outlet 8 are all located in the water storage part 502.
[0049] It should be noted that the water inlet 4 collects the water received from the washing cavity through the water collection section 501 and into the water storage section 502, so that the water in the dishwasher is temporarily stored in the water storage section 502 for subsequent recycling. Since the water storage section 502 does not need to hold a large amount of water, the storage space of the water storage section 502 is minimized to reduce the space occupied by the water storage section 502 in the entire dishwasher.
[0050] It is understandable that the dishwasher provided in this embodiment, since the water storage section should not be set to an excessively large volume, can effectively increase the water collection area of the water storage section through the funnel structure of the water collection section.
[0051] In one embodiment, see Figure 3 , Figure 3 This is a schematic diagram of the structure of the electrical control box shown in an exemplary embodiment of the present invention. See also: Figure 3 The dishwasher also includes an electrical control box, which is located between the outer shell and the inner shell. The electrical control box includes an electrical control box base 10, an electrical control box top cover 11, a frequency converter drive board 12, and a cooling fan 13. The electrical control box base 10 and the electrical control box top cover 11 are fastened together. The inner wall of the electrical control box base 10 and the inner wall of the electrical control box top cover 11 form the inner cavity of the electrical control box. The frequency converter drive board 12 is located in the inner cavity of the electrical control box. The cooling fan 13 is located on the outer wall of the electrical control box top cover 11. The electrical control box top cover 11 is provided with an air outlet 14. The frequency converter drive board 12 is provided with heat sinks. The position of the air outlet 14 corresponds to the position of the heat sinks. The air inlet of the cooling fan 13 corresponds to the position of the air outlet 14.
[0052] It should be noted that the dishwasher used for demonstration is used frequently, and the inverter drive board 12 in the control box will increase in temperature. If it cannot be effectively cooled, it will cause overheating and damage. The heat of the inverter drive board 12 is first dissipated by the heat sink, and then the heat of the heat sink is discharged from the control box through the air outlet 14 on the top cover 11 of the control box and the cooling fan 13.
[0053] It is understood that the dishwasher provided in this embodiment, by adding a heat dissipation structure to the electrical control box, can effectively dissipate the heat of the frequency converter drive board, effectively reduce overheating damage, and make the dishwasher operate more stably.
[0054] In one embodiment, a heat dissipation vent is provided on the housing, and the heat dissipation vent is located at the air outlet 15 of the cooling fan 13.
[0055] It is understood that the dishwasher provided in this embodiment has heat dissipation vents on its outer casing, which can quickly exhaust the hot air discharged by the cooling fan to the outside of the dishwasher to achieve better heat dissipation.
[0056] In one embodiment, a notch 16 is provided between the base 10 and the top cover 11 of the control box, through which the power connection wire of the frequency converter drive board 12 can pass and the notch 16 can serve as a cooling air inlet inside the control box.
[0057] It is understood that the dishwasher provided in this embodiment uses the wire hole as a cooling air inlet, which can provide the required cooling air to the interior, improve the cooling effect, and effectively reuse the existing equipment structure to reduce processing costs.
[0058] In one embodiment, both the inner and outer shells are made of transparent material.
[0059] It is understood that the dishwasher provided in this embodiment, by using transparent materials for both the inner and outer shells, allows for a better display of the dishwasher's internal operation.
[0060] In one embodiment, operation button 3 is a piano key switch.
[0061] It should be noted that the key switch is a button with a self-locking function. The switch signals for functions such as drainage, washing, main shut-off, and water distribution are input to the internal control unit of the main control board through the key switch to realize the corresponding function display.
[0062] It is understandable that the dishwasher provided in this embodiment allows sales staff to quickly and flexibly operate various functions of the dishwasher via piano key switches, which can effectively improve the speed of function operation.
[0063] In one embodiment, the dishwasher also includes a main control board and a low-voltage switch electrically connected to the main control board. The low-voltage switch is disposed on the door 2 and can contact the housing 1 when the door 2 is opened or closed. The main control board is electrically connected to the washing pump of the rinsing device.
[0064] It should be noted that if the transparent door of the dishwasher is suddenly opened by a consumer or salesperson during a demonstration wash, the high-pressure water jet inside may spray out, potentially wetting people and the surrounding environment, causing unnecessary trouble. The purpose of the low-voltage switch: The moment the door is opened, the low-voltage switch is triggered, sending an electrical signal to the main control board. Upon recognizing the signal, the main control board stops the washing pump.
[0065] It is understood that the technical solution provided in this embodiment can effectively avoid the problem of internal high-pressure water jets being ejected due to non-compliant operations.
[0066] In one embodiment, an overflow switch is provided between the bottom of the inner shell and the bottom of the outer shell, and the overflow switch is electrically connected to the main control board.
[0067] It should be noted that during the dishwasher's demonstration wash cycle, water may leak from the washing chamber. The overflow switch uses a micro switch. When water leaks from the washing chamber and flows between the inner and outer shells on the bottom surface of the casing, it triggers the overflow switch. The overflow switch sends an electrical signal to the main control board. After recognizing the overflow switch signal, the main control board controls the washing pump to stop running and simultaneously sounds an alarm or turns on an alarm light.
[0068] It is understandable that the technical solution provided in this embodiment can quickly detect water leakage problems, enabling staff to deal with them in a timely manner and reduce losses.
