Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pump, and more particularly, to a pump with a heater formed so as to be suitable for use in, for example, a hot-water circulation filter for a domestic bathtub or a filter for an ornamental fish tank.

[0002]

[Prior art]

 As shown in FIG. 3, a conventional pump of this type is usually provided with a tank 2 having a built-in heater above a housing 1 (hereinafter referred to as conventional example A), or as shown in FIG. For example, a tank 2 equipped with a heater 4 for heating a fluid was connected to a fluid discharge pipe 3 (hereinafter referred to as Conventional Example B).

[0003]

[Problems to be solved by the device]

 By the way, the pumps used in the hot-water circulation filtration system for domestic bathtubs and the filtration systems for ornamental fish tanks are installed in a narrow space, so they have a warm water-saving function while saving heat. It is desirable that it be formed so that space can be saved and that the piping connection during installation can be done easily and easily.

However, in the case of the conventional example A, although the installation space is the area occupied by the pump, the upper space of the pump is occupied by the tank containing the heater, so that the upper space of the pump is narrowed. There was a problem that it was unavoidable, and it took time to connect it because it had to be connected to the tank.

In addition, in the case of the conventional example B, a tank for heating hot water as a fluid is placed next to the pump separately from the pump. However, there is a problem that extra space is required and, as in the case of the conventional example A, it takes a lot of time and labor to dispose the tank.

The present invention is intended to solve the problems of such conventional products. Therefore, the technical problem of this plan is that the space around the pump can be saved by making it possible to omit the installation space and the installation space occupied by the tank with a built-in heater for heating the fluid. It is to provide a pump with a heater configured to eliminate the time and effort associated with connecting pipes.

[0007]

[Means for Solving the Problems]

 This proposal adopts the following technical means to solve the above problems. That is, the present invention is a pump in which a fluid suction pipe 5 is provided at a central position on the upper surface of the housing 1, and a discharge pipe 3 for discharging the fluid sucked from the suction pipe 5 is provided in the upper portion of the housing 1. The fluid sent out to the discharge pipe 3 through the internal space S is formed in the internal space S formed by the inner cylinder 6 inside the housing 1 communicating with the suction pipe 5 and the inner peripheral wall of the housing 1. It is characterized in that a heater 7 for heating is provided.

In this case, according to the present invention, it is preferable that the heater 7 is wound around the inner cylinder 6 and formed into a coil shape so that heating can be performed uniformly and efficiently at any position of the internal space S. Yes.

The present invention may also include a sensor 8 for detecting the temperature of the fluid in the internal space S. In this case, there is an advantage that the temperature of the fluid in the internal space S can be directly controlled by the heater 7 by the detection signal from the sensor 8 and the temperature of the fluid to be discharged can be controlled accurately to a desired state.

Further, in the present invention, it is preferable that the fluid discharge pipe 3 is provided on the upper surface of the housing 1 so that the heated hot water flows out smoothly.

[0011]

[Embodiment of the invention]

 An embodiment of the pump of the present invention will be described below with reference to the accompanying drawings. In the pump of the present embodiment of this embodiment, a suction pipe 5 for hot and cold water as a fluid is provided at a central position of the upper surface of a housing 1 formed in a vertical cylindrical shape. Further, a discharge pipe 3 for the fluid sucked from the suction pipe 5 is provided on the upper surface of the pump housing 1.

Reference numeral 6 denotes an inner cylinder that communicates with the suction pipe 5 and is located inside the housing 1. In the internal space S formed by the inner cylinder 6 and the housing 1, a heater 7 for heating the fluid sent to the discharge pipe 3 through the internal space S is arranged. This heater 7 is wound around the inner cylinder 6 in this embodiment, apart from the inner cylinder 6 and concentrically with the inner cylinder 6, and is formed in a coil shape. Reference numeral 7a is a heater terminal.

Reference numeral 8 is a sensor that detects the temperature of the fluid in the internal space S. This sensor 8 is made of, for example, bimetal.

Reference numeral 9 is a drive unit for performing suction and delivery operations of the fluid, and 10 is a motor as an operation source of the drive unit 9. Reference numeral 11 denotes a thermistor. The thermistor 11 is configured to detect the temperature of hot water flowing from the suction pipe 5 and output a signal for turning on the heater 7 when the temperature is lower than a predetermined temperature.

Next, the operation of the pump of the present invention will be described. Hot water as a fluid is sucked from the suction pipe 5 by the action of the drive unit 9 when the motor 10 is driven, and is discharged from the discharge pipe 3 through the inner cylinder 6 and the internal space S. In this process, the heater 7 arranged in the internal space S heats the hot water as a fluid, and the heated fluid is sent out from the discharge pipe 3.

[0016]

[Effect of the invention]

 As described above, the present invention is for heating the fluid sent out to the above-mentioned discharge pipe through this internal space to the internal space formed by the housing and the inner cylinder in the housing communicating with the suction pipe. Since the heater is provided, there is no need to newly provide a tank containing the heater in order to heat the fluid. Therefore, in this plan, the tank with a built-in heater can be omitted, so the installation space and installation space can be saved accordingly, and not only the space around the pump can be saved, but also the time and effort associated with the piping connection to the tank can be saved. It has a practically excellent effect that it can be wiped out.

When the heater is wound around the inner cylinder and formed into a coil shape as described in claim 2, the surface area of the heater can be increased, and the heater can be evenly distributed at any position of the internal space. There is an advantage that heating can be performed efficiently.

When a sensor for detecting the temperature of the fluid in the internal space is provided as described in claim 3, the temperature of the fluid to be discharged can be accurately controlled to a desired state.

Further, when the fluid discharge pipe is provided on the upper surface of the housing as described in claim 4, since the discharge pipe is arranged along the direction in which the suction feed force of the drive unit is applied, As compared with the case where the pipe is formed on the upper side surface of the housing, for example, it is possible to smoothly discharge the heated fluid.
