[0003] However, the instant heating device with the above structure still has the following deficiencies: (1) The above instant heating water dispenser is provided with a circuit board for controlling the pipeline heater. During operation, some electrical components on the circuit board need to dissipate heat. The existing water dispenser realizes the heat dissipation of the circuit board by setting a cooling fan at the position corresponding to the circuit board on the casing. However, this method adds a component of the cooling fan, increases the overall cost of the product and the overall installation of the product. In addition, the heat dissipation effect of this heat dissipation method is also relatively average. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the above-mentioned prior art, and to provide an instant heating device that is convenient for the circuit board to dissipate heat and has a relatively simple overall structure of the product.

[0005] The purpose of the present invention is achieved as follows: An instant heating device, comprising a frame body, an instant heating pipe and a circuit board. The circuit board and the instant heating pipe are both fixed on the frame body and the circuit board is electrically connected to the instant heating pipe. One end of the instant heating pipe is connected with a water inlet pipeline, and the other end of the instant heating pipe is provided with a hot water outlet. The feature is that it further comprises a thermostat. One end of the thermostat is close to the instant heating pipe, and the other end of the thermostat is connected to the circuit board. A comprehensive water tank is arranged on the water inlet pipeline, and the inner cavity of the comprehensive water tank is communicated with the water inlet pipeline. One end of an electrical component on the circuit board is fixed with a heat dissipation piece. The heat dissipation piece is placed on the comprehensive water tank and a part of the heat dissipation piece extends into the inner cavity of the comprehensive water tank. For this instant heating device, the comprehensive water tank on the water inlet pipeline cooperates with the heat dissipation piece of the electrical component to realize the heat exchange between the water in the comprehensive water tank and the heat dissipation piece, which not only realizes the heat dissipation of the heat dissipation piece and is beneficial to the stable operation of the electrical component, but also has a certain preheating effect on the water in the comprehensive water tank. At the same time, the heat dissipation of the electrical component can be realized without adding a heat dissipation device such as a fan, making the overall structure of the product relatively simple. Moreover, the thermostat and the circuit board are relatively compact, reducing the overall volume of the product.

[0006] The object of the present invention can also be solved by the following technical measures: Specifically further, the comprehensive water tank comprises a box body and an upper cover. The inner cavity is opened on the box body and the upper cover covers the upper opening of the inner cavity. The heat dissipation piece is placed on the upper cover and a part of the heat dissipation piece passes through the upper cover and extends into the inner cavity, so as to facilitate the direct contact between the heat dissipation piece and the water in the inner cavity. At the same time, the structure of the comprehensive water tank is relatively simple and its implementation is relatively easy.

[0007] Specifically further, it further comprises a dry-burning prevention detection piece. The dry-burning prevention detection piece is placed on the upper cover and the dry-burning prevention detection piece is electrically connected to the circuit board. If the dry-burning prevention detection piece detects that there is no water passing through the comprehensive water tank, that is, the water inlet pipeline does not transport water to the instant heating pipe, the dry-burning prevention detection piece gives a signal to the circuit board, so that the circuit board controls the heating pipe to stop working, thereby avoiding the dry burning of the heating pipe.

[0008] Specifically further, an upper surrounding wall extends upward from the upper part of the upper cover. An installation recess is enclosed inside the upper surrounding wall. A through hole is opened at the bottom of the installation recess. The dry-burning prevention detection piece is placed on the installation recess and the detection head of the dry-burning prevention detection piece passes downward through the through hole and extends into the inner cavity, so as to facilitate the dry-burning prevention detection piece to directly and stably detect whether there is water passing through the inner cavity. At the same time, the installation recess provides a stable installation space for the dry-burning prevention detection piece, which is beneficial to the stable operation of the dry-burning prevention detection piece.

[0009] Specifically, further, the heat dissipation member is a T-shaped aluminum radiator. The upper cover extends upward to form a hollow placement portion. The upper part of the aluminum radiator is placed on the hollow placement portion, and the lower part of the aluminum radiator extends into the inner cavity. The electrical components are connected to the upper part of the aluminum radiator. The hollow placement portion can not only realize the installation of the aluminum radiator on the upper cover, but also enable the lower part of the aluminum radiator to extend into the inner cavity. Its structural setting is ingenious and the implementation effect is good.

[0010] Specifically, further, the water inlet pipeline includes a first water pipe and the comprehensive water tank. The first water pipe is fixed on the frame. One end of the first water pipe is connected to one end of the instant heating pipe, and the other end of the first water pipe is connected to the box body. The inner cavity of the box body is communicated with an external water source. The comprehensive water tank can act as an intermediate transmission carrier of the external water source, so that the water inlet pipeline can achieve better heat exchange and water inlet detection functions. At the same time, the comprehensive water tank realizes the water connection with the instant heating pipe through the first water pipe, and its implementation effect is better.

[0011] Specifically, further, it further includes a second water pipe and a fixing wall. The fixing wall is connected to the frame, and the two sides of the fixing wall are respectively connected to the first water pipe and the second water pipe. One end of the second water pipe is connected to an external water source, and the other end of the second water pipe is connected to the comprehensive water tank. The first water pipe and the second water pipe are arranged on both sides of the fixing wall in a left-right parallel manner. It is convenient for the box body to be connected to the external water source through the second water pipe to realize the diversified setting of the water inlet position of the water inlet pipeline. Moreover, the fixing wall can simultaneously realize the installation and fixation of the first water pipe and the second water pipe on the frame.

[0012] Specifically, further, the circuit board is fixed on the upper part of the frame, the first water pipe is fixed on the lower part of the frame, the comprehensive water tank is connected to the upper end of the first water pipe and the comprehensive water tank is located in the middle of the frame. One end of the electrical component is connected to the lower part of the circuit board, and the other end of the electrical component extends downward out of the circuit board. The lower surface of the electrical component is connected with the heat dissipation member. So that the circuit board, the comprehensive water tank and the first water pipe are arranged on the frame in an upper-middle-lower position relationship. This position relationship setting is ingenious and is convenient for the heat dissipation member of the electrical component on the circuit board to cooperate with the comprehensive water tank.

[0013] Specifically, further, it further includes a water pump. A partition portion is provided on the inner cavity, so that the inner cavity is divided into a detection space and a heat exchange space. The dry-burning prevention detection member is located above the detection space. A part of the heat dissipation member extends into the heat exchange space. The water pump is fixed on the frame, and the inlet of the water pump is communicated with the detection space, and the outlet of the water pump is communicated with the heat exchange space. By dividing the inner cavity into two independent spaces through the partition portion, it is beneficial to the independent and stable implementation of the detection by the dry-burning prevention detection member and the heat exchange by the heat dissipation member. Moreover, through the water pump, the water connection between the detection space and the heat exchange space is realized, and it also enables the water inlet pipeline to stably supply water to the instant heating pipe.

[0014] Specifically, further, it further includes an elastic electrode hoop. The elastic electrode hoop is sleeved on the outer periphery of the instant heating tube, and the elastic electrode hoop is electrically connected to the circuit board. An elastic opening is provided on the elastic electrode hoop. The frame body includes a connected left shell and a right shell. A left limiting portion is provided on the left shell, and a right limiting portion is provided on the right shell. The portion of the elastic electrode hoop located on the left side of the elastic opening abuts against the left limiting portion, and the portion of the elastic electrode hoop located on the right side of the elastic opening abuts against the right limiting portion. The elastic electrode hoop is restricted and fixed through the cooperation of the left limiting portion and the right limiting portion, so that the elastic electrode hoop can be stably installed on the outer periphery of the instant heating tube, that is, the elastic electrode hoop can be fixed on the instant heating tube through the connected left shell and right shell. Its setting is ingenious and the implementation effect is good.

[0015] Specifically, further, The beneficial effects of the present invention are as follows: (1) For this instant heating device, the comprehensive water tank on the water inlet pipeline is used in cooperation with the heat dissipation part of the electrical components to realize the heat exchange between the water in the comprehensive water tank and the heat dissipation part. It not only realizes the heat dissipation of the heat dissipation part, which is beneficial to the stable operation of the electrical components, but also has a certain preheating effect on the water in the comprehensive water tank. At the same time, the heat dissipation of the electrical components can be realized without adding a heat dissipation device such as a fan, making the overall structure of the product relatively simple. Moreover, the thermostat and the circuit board are relatively compact, reducing the overall volume of the product.

[0016] (2) The comprehensive water tank can act as an intermediate transmission carrier for the external water source, so that the water inlet pipeline can realize better heat exchange and water inlet detection functions. At the same time, the comprehensive water tank is connected to the instant heating tube through the first water pipe, and its implementation effect is good.

[0017] (3) The elastic electrode hoop is restricted and fixed through the cooperation of the left limiting portion and the right limiting portion, so that the elastic electrode hoop can be stably installed on the outer periphery of the instant heating tube, that is, the elastic electrode hoop can be fixed on the instant heating tube through the connected left shell and right shell.
