Description

Technical Field

[0001] This application relates to the field of washing machine technology, specifically a washing machine water tank coil heating device. Background Technology

[0002] The tunnel-type continuous washing machine (laundry dragon) mainly consists of an automatic weighing loader, washing cages, a press dryer, a shuttle, and a through-type dryer. The automatic weighing loader can quantitatively and qualitatively load the linens to be washed; the washing cage is the core component, with multiple washing chambers designed to efficiently wash the linens; the press dryer is used to remove the water from the washed linens; the shuttle automatically sends the pressed linens into the dryer; and the through-type dryer dries the linens. All parts work together to realize a continuous automated process from washing, dehydration to drying of linens. It has the advantages of high efficiency, energy saving, environmental protection, and hygiene, and can greatly improve laundry efficiency and quality. It is widely used in various large-scale laundry facilities.

[0003] However, the washing water in the washing machine's tank is pumped into the washing machine, and the temperature of the washing water in the tank is measured by a temperature sensor. The normal temperature of the water in the tank is relatively low, which is not conducive to the proper functioning of the detergent and causes waste in terms of customer costs. However, with the development of detergents, it is required that the temperature of the washing water in the tank should not exceed 42 degrees Celsius, which is more conducive to the proper functioning of the detergent and saves costs. In extremely cold places where the water temperature is generally low, the washing water temperature in the tank is prone to being too low or even freezing, which makes it difficult for the detergent to dissolve in the water, thus reducing the washing effect of the linens.

[0004] Therefore, it is necessary to provide a washing machine water tank coil heating device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] The purpose of this invention is to provide a water tank coil heating device for a washing machine to solve the problems mentioned in the background art.

[0007] The technical solution adopted by this application to solve its technical problem is:

[0008] A washing machine water tank coil heating device includes a washing machine water tank, in which a heating component for heating washing water is installed. The heating component includes an angle seat valve, a coil, and a bracket. The bracket is fixedly installed on the bottom surface of the water tank. The coil is fixedly installed on the bottom of the water tank via the bracket. The angle seat valve is connected to one end of the coil via a flange. The top of the angle seat valve is provided with a steam inlet. Steam flows through the angle seat valve in the coil to heat the washing water in the water tank.

[0009] The other end of the coil is connected to one end of the shut-off valve via a flange, and the other end of the shut-off valve is connected to the drain valve.

[0010] Preferably, the coil is mounted on the bracket in a tortuous path.

[0011] Preferably, the bracket includes an upper fixed frame and a lower fixed frame, the two ends of the upper fixed frame and the lower fixed frame are fixedly installed by screws, and the coil is clamped and installed in the gap between the upper fixed frame and the lower fixed frame.

[0012] Preferably, a temperature sensor is fixedly installed on the side wall of the water tank.

[0013] Preferably, a water pump is fixedly installed on the side wall of the water tank. The water inlet of the water pump is fixedly installed to the side wall of the water tank through a water suction pipe, and the end of the water suction pipe is placed on the inner bottom of the water tank. The water pump draws washing water from the water tank through the water suction pipe and provides washing water to the washing chamber of the washing machine through the water outlet.

[0014] Preferably, a liquid level sensor is installed on the top of the water tank, a water inlet is provided on the side wall of the water tank, a water replenishment port is provided on one side wall of the water tank, and an overflow port is provided on the other side wall of the water tank. An overflow chamber is fixedly connected to the inner side wall of the water tank located at the overflow port.

[0015] Preferably, a drain valve is installed at the bottom of the water tank.

[0016] The beneficial effects of this application are:

[0017] 1. In this solution, a heating assembly is formed by angle seat valves, coils, and brackets. Steam flows inside the coils, and the washing water is heated by heat transfer. The coils are installed in a tortuous path, which increases the contact area with the washing water and improves the heating efficiency. Even in extremely cold environments, the water temperature can be quickly raised to a suitable range to ensure that the detergent dissolves properly and to guarantee the washing effect of the linens.

[0018] 2. In addition, the temperature sensor can monitor the temperature of the washing water in the tank in real time and flexibly adjust the working status of the heating component. When the water temperature is lower than the set value, the steam flow is increased to raise the water temperature; when it is higher than the set value, the heating is reduced or stopped. This ensures that the water temperature is stable within the range of no more than 42 degrees Celsius, which not only meets the temperature requirements for the detergent to play its best role and promotes the detergent to fully dissolve in the water, but also avoids energy waste caused by excessively high water temperature, thereby saving customer costs.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0031] Please see Figure 1-5 The embodiments provided by this utility model are as follows:

[0032] like Figure 1 As shown, a washing machine water tank coil heating device includes a washing machine water tank 1, which serves as the core container of the entire device and holds the washing water. A water pump 5 is fixedly installed on the side wall of the water tank 1. The water inlet of the water pump 5 is fixedly installed to the side wall of the water tank 1 through a water suction pipe 52, and the end of the water suction pipe 52 is placed on the inner bottom of the water tank 1. The water pump 5 draws washing water from the water tank 1 through the water suction pipe 52 and provides washing water to the washing chamber of the washing machine through the water outlet 51. The water pump 5 is connected to the water tank 1 through the water suction pipe 52. When the water pump 5 starts, the centrifugal force generated by the rotation of the impeller creates a negative pressure in the water suction pipe 52, thereby drawing out the washing water at the bottom of the water tank 1. The outlet 51 of the water pump 5 is connected to the washing chamber of the washing machine. Under pressure, the washing water is transported to the washing chamber through the pipe to meet the water volume and water pressure requirements of the washing machine during the washing process. The water pump 5 realizes the directional circulation of washing water between the water tank 1 and the washing chamber, ensuring the continuous operation of the washing machine.

[0033] A liquid level sensor 9 is installed on the top of water tank 1. A water inlet 2 is located on the side wall of water tank 1, a water replenishment inlet 3 is located on one side wall of water tank 1, and an overflow outlet 4 is located on the other side wall of water tank 1. An overflow chamber 41 is fixedly connected to the inner wall of water tank 1 located at the overflow outlet 4. A drain valve 8 is installed at the bottom of water tank 1. The liquid level sensor 9 is installed on the top of water tank 1. By detecting the liquid level in water tank 1, the sensor converts the signal into an electrical signal and transmits it to the control system. When the water level in water tank 1 is lower than the set lower limit, the control system issues a command to open the water inlet 2, allowing external water to flow into water tank 1 for replenishment. The water replenishment inlet 3 is for manual or other control-based additional water replenishment in special circumstances, such as a rapid drop in water level. When the water level in water tank 1 reaches or exceeds the set upper limit, washing water flows into the overflow chamber 41 through the overflow outlet 4, preventing water tank 1 from overflowing due to excessive water level and ensuring safe system operation.

[0034] like Figures 2-5 As shown, a heating assembly 7 for heating washing water is installed in the water tank 1. The heating assembly 7 includes an angle seat valve 71, a coil 72, and a bracket 73. The bracket 73 is fixedly installed on the bottom surface of the water tank 1. The coil 72 is fixedly installed at the bottom of the water tank 1 through the bracket 73. The bracket 73 provides a stable support structure for the coil 72. The angle seat valve 71 is installed by connecting to one end of the coil 72 through a flange. The top of the angle seat valve 71 is provided with a steam inlet 711. Steam flows through the angle seat valve 71 in the coil 72 to heat the washing water in the water tank 1. Specifically, the coil 72 is installed on the bracket 73 in a tortuous path to increase the contact area with the washing water in the water tank 1.

[0035] The other end of the coil 72 is connected to one end of the gate valve 74 via a flange, and the other end of the gate valve 74 is connected to the steam trap 75.

[0036] Angle seat valve 71 is connected to one end of coil 72 via a flange. When steam enters angle seat valve 71 through steam inlet 711, it enters coil 72 under pressure. Since the outside of coil 72 is the washing water in water tank 1, according to the principle of heat transfer, the heat of the steam is transferred to the washing water through the wall of coil 72, thus heating the washing water. Shut-off valve 74 controls the flow of steam in coil 72. When heating needs to be stopped, shut-off valve 74 is closed to block the steam from entering. Drain valve 75 is used to drain the water condensed from the steam in coil 72, preventing the accumulation of condensate from affecting the heating effect of the steam and the normal operation of coil 72.

[0037] The bracket 73 includes an upper fixed frame and a lower fixed frame. The two ends of the upper fixed frame and the lower fixed frame are fixedly installed by screws. The coil 72 is clamped and installed in the gap between the upper fixed frame and the lower fixed frame. When installing the coil 72, the coil 72 is placed in the gap between the upper fixed frame and the lower fixed frame, and the upper and lower fixed frames are tightened by screws to fix the coil 72 firmly on the bracket 73. This allows the coil 72 to maintain a stable position in the water tank 1 and prevents displacement or shaking under conditions such as steam heating and water flow impact.

[0038] To better control the water temperature in the water tank 1, a temperature sensor 6 is fixedly installed on the side wall of the water tank 1. Through built-in temperature sensing elements, such as thermocouples and thermistors, the sensor detects the temperature change of the washing water in the water tank 1. The temperature sensing element converts the temperature signal into an electrical signal and transmits it to the control system. The control system compares the received temperature signal with the set temperature value. When the actual water temperature is lower than the set value, the control system controls the heating component 7 to increase the heating intensity, such as by increasing the steam flow. When the actual water temperature is higher than the set value, the control system controls the heating component 7 to reduce heating or stop heating, thereby achieving precise control of the washing water temperature in the water tank 1.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
